示例性的，第一信道状态信息，例如下述实施例中所说的用于衡量信道传输上行数据时的情况的信道状态信息。在一种可能的情况中，信道状态信息包括但不限于信道中的通信信号、干扰信号强度等。Exemplarily, the first channel state information is, for example, the channel state information used to measure the situation when the channel transmits uplink data in the following embodiments. In a possible situation, the channel state information includes but is not limited to the communication signal and interference signal strength in the channel.
示例性的，设定周期，例如下述实施例中所说的在该信道发射信号的周期等。Exemplarily, a period is set, such as the period of transmitting a signal on the channel as described in the following embodiments.
示例性的，发射功率限制值，例如下述实施例中所说的pLimit。Exemplarily, the transmission power limit value, for example, pLimit mentioned in the following embodiments.
示例性的，电磁波吸收比值限制值，例如下述实施例中所说的SAR限制值。Exemplarily, the electromagnetic wave absorption ratio limit value is, for example, the SAR limit value mentioned in the following embodiments.
这样，通过识别当前的业务场景是否为增强型移动带宽和/或高可靠低时延通信的第一业务，进而在确定当前业务为第一业务时，在第一业务的整个作业过程中周期性地评估第一业务对应的第一信道在当前周期内的第一发射功率和该周期内第一信道对应的功率回退值，进而根据第一发射功率、功率回退值，以及电子设备当前所在区域对应的发射功率限制值，动态调整第一发射功率，以获得适合该周期的第一目标发射功率，最终以第一目标发射功率，在第一信道中发射信号，从而使得第一业务的整个作业过程，不仅能够以合适的发射功率发射信号，保证通信质量，同时又可以确保用户处于安全的电磁辐射范围。In this way, by identifying whether the current service scenario is the first service of enhanced mobile bandwidth and/or highly reliable and low-latency communication, and then when it is determined that the current service is the first service, the first transmission power of the first channel corresponding to the first service in the current cycle and the power backoff value corresponding to the first channel in the cycle are periodically evaluated during the entire operation process of the first service, and then according to the first transmission power, the power backoff value, and the transmission power corresponding to the area where the electronic device is currently located, The rate limit value is determined, and the first transmission power is dynamically adjusted to obtain the first target transmission power suitable for the period. Finally, the signal is transmitted in the first channel with the first target transmission power, so that the entire operation process of the first service can not only transmit the signal with the appropriate transmission power to ensure the communication quality, but also ensure that the user is in a safe electromagnetic radiation range.
根据第一方面，根据第一信道状态信息，确定第一信道在当前周期的功率回退值，包括：根据第一信道状态信息，确定第一信道在当前周期的上行调度率；根据上行调度率，确定第一信道在当前周期的上行占比；根据上行占比，确定第一信道在当前周期的功率回退值。According to the first aspect, based on the first channel state information, the power backoff value of the first channel in the current period is determined, including: based on the first channel state information, determining the uplink scheduling rate of the first channel in the current period; based on the uplink scheduling rate, determining the uplink proportion of the first channel in the current period; based on the uplink proportion, determining the power backoff value of the first channel in the current period.
通过根据当前评估周期内的第一信道状态信息确定第一信道在该周期内需要回退的功率值，从而保证在第一发射功率的基础上，回退该功率回退值得到的第一目标发射功率能够始终小于发射功率限制值，进而确保电子设备以调整获得的第一目标发射功率发射信号时产生的电磁辐射在安全范围内，保证用户安全。By determining the power value that needs to be backed off for the first channel within the current evaluation period based on the first channel status information within the period, it is ensured that, on the basis of the first transmission power, the first target transmission power obtained by backing off the power back-off value can always be less than the transmission power limit value, thereby ensuring that the electromagnetic radiation generated when the electronic device transmits a signal with the adjusted first target transmission power is within a safe range, thereby ensuring user safety.
根据第一方面，或者以上第一方面的任意一种实现方式，根据第一发射功率、功率回退值和发射功率限制值，确定第一目标发射功率，包括：在第一发射功率大于发射功率限制值时，控制第一发射功率，回退所述功率回退值，得到第一目标发射功率；其中，第一目标发射功率小于发射功率限制值。According to the first aspect, or any implementation method of the first aspect above, a first target transmit power is determined based on the first transmit power, the power backoff value and the transmit power limit value, including: when the first transmit power is greater than the transmit power limit value, controlling the first transmit power, backing off the power backoff value, and obtaining the first target transmit power; wherein the first target transmit power is less than the transmit power limit value.
由此，在当前周期内确定的第一信道支持的第一发射功率大于发射功率限制值时，才控制第一发射功率回退根据第一信道状态信息确定的功率回退值，这样既可确保用户处于安全的电磁辐射范围，又能够避免在每个周期都将第一发射功率回退确定的功率回退值，从而保证了通信质量。Therefore, when the first transmission power supported by the first channel determined in the current cycle is greater than the transmission power limit value, the first transmission power is controlled to fall back to the power backoff value determined according to the first channel state information. This can not only ensure that the user is in a safe electromagnetic radiation range, but also avoid falling back the first transmission power to the determined power backoff value in each cycle, thereby ensuring communication quality.
根据第一方面，或者以上第一方面的任意一种实现方式，控制第一发射功率，回退所述功率回退值，得到第一目标发射功率，包括：根据功率回退值确定当前周期对应的发射功率调整步长，发射功率调整步长小于功率回退值；根据发射功率调整步长，在当前周期内，控制第一发射功率逐步回退，直至回退功率回退值；将回退功率回退值后的第一发射功率作为第一目标发射功率。According to the first aspect, or any one of the implementation methods of the first aspect above, the first transmit power is controlled, the power backoff value is backed off, and the first target transmit power is obtained, including: determining the transmit power adjustment step corresponding to the current period according to the power backoff value, the transmit power adjustment step is less than the power backoff value; according to the transmit power adjustment step, within the current period, the first transmit power is controlled to gradually backoff until the power backoff value is backed off; and the first transmit power after the power backoff value is backed off is used as the first target transmit power.
由此，通过确定小于功率回退值的发射功率调整步长，即小步长，进而根据小步长控制第一发射功率逐步回退，直至回退功率回退值，从而在将第一发射功率发射信号对应的电磁辐射控制到安全范围的同时，也可以避免用户体验的突然变差，使得用户体验变化过程平滑。Therefore, by determining a transmission power adjustment step that is smaller than the power backoff value, that is, a small step, and then controlling the first transmission power to gradually back off according to the small step until the power backoff value is reached, the electromagnetic radiation corresponding to the first transmission power transmission signal is controlled to a safe range while avoiding a sudden deterioration in user experience, thereby making the user experience change process smooth.
根据第一方面，或者以上第一方面的任意一种实现方式，根据功率回退值确定当前周期对应的发射功率调整步长，包括：根据功率回退值和当前周期的时长，确定发射功率调整步长。According to the first aspect, or any implementation of the first aspect above, determining the transmit power adjustment step corresponding to the current period according to the power backoff value includes: determining the transmit power adjustment step according to the power backoff value and the duration of the current period.
示例性的，根据功率回退值和当前周期的时长，确定发射功率调整步长的方式，例如为根据功率回退值和当前周期的时长求取单位时间的均值。这样，在基于发射功率调整步长调整发射功率时，可以匀速降低发射功率，使得用户体验过程更加平滑。Exemplarily, the method of determining the transmission power adjustment step length according to the power backoff value and the duration of the current cycle is, for example, to obtain the average per unit time according to the power backoff value and the duration of the current cycle. In this way, when adjusting the transmission power based on the transmission power adjustment step length, the transmission power can be uniformly reduced, making the user experience process smoother.
根据第一方面，或者以上第一方面的任意一种实现方式，根据第一发射功率、功率回退值和发射功率限制值，确定第一目标发射功率，还包括：在第一发射功率不大于发射功率限制值时，将第一发射功率作为第一目标发射功率。According to the first aspect, or any implementation method of the first aspect above, the first target transmit power is determined according to the first transmit power, the power backoff value and the transmit power limit value, and also includes: when the first transmit power is not greater than the transmit power limit value, the first transmit power is used as the first target transmit power.
由此，在第一发射功率不大于发射功率限制值的情况下，即便根据第一信道状态信息确定的了功率回退值，也可以不对第一发射功率进行调整，而是直接以第一发射功率发射信号，这样在确保用户处于安全的电磁辐射范围的情况下，又能够使电子设备当前有一个较高的发射功率，保证了通信质量，进而保证了用户使用体验。Therefore, when the first transmit power is not greater than the transmit power limit value, even if the power backoff value is determined according to the first channel state information, the first transmit power may not be adjusted, but the signal may be directly transmitted at the first transmit power. In this way, while ensuring that the user is in a safe electromagnetic radiation range, the electronic device can currently have a higher transmit power, thereby ensuring the communication quality and further ensuring the user experience.
根据第一方面，或者以上第一方面的任意一种实现方式，识别当前业务为第一业务，包括：获取电子设备当前产生的数据流；对数据流进行业务识别，确定提供数据流的应用；根据应用的属性，确定应用对应的业务关注的网络特性；在业务关注的网络特性满足增强型移动宽带和/或高可靠低时延通信的网络特性时，确定当前业务为第一业务。According to the first aspect, or any implementation method of the first aspect above, identifying the current service as the first service includes: obtaining the data stream currently generated by the electronic device; performing service identification on the data stream to determine the application providing the data stream; determining the network characteristics of the service corresponding to the application based on the attributes of the application; when the network characteristics of the service meet the network characteristics of enhanced mobile broadband and/or high-reliability and low-latency communication, determining that the current service is the first service.
示例性的，增强型移动带宽的网络特性，例如下述实施例中所说的更大的网络吞吐量、更高的峰值速率、低延时等。Exemplary network characteristics of enhanced mobile bandwidth include, for example, greater network throughput, higher peak rate, low latency, etc. as described in the following embodiments.
示例性的，高可靠低时延通信的网络特性，例如下述实施例中所说的高可靠性和超低时延等。Exemplary network characteristics of high-reliability and low-latency communications include, for example, high reliability and ultra-low latency as described in the following embodiments.
根据第一方面，或者以上第一方面的任意一种实现方式，方法还包括：识别当前业务为第二业务，第二业务关注的网络特性与第一业务关注的网络特性不相同；在第二业务的作业过程中，采用限制发射功率峰值或限制平均时间内的发射功率的方式，调整第二业务对应的第二信道的第二发射功率；根据调整后的第二发射功率，在第二信道发射信号。According to the first aspect, or any implementation method of the first aspect above, the method also includes: identifying that the current service is a second service, and the network characteristics that the second service focuses on are different from the network characteristics that the first service focuses on; during the operation of the second service, adjusting the second transmission power of the second channel corresponding to the second service by limiting the transmission power peak or limiting the transmission power within the average time; and transmitting a signal on the second channel according to the adjusted second transmission power.
这样，对于网络要求低于第一业务的业务(第二业务)，直接采用限制发射功率峰值或限制平均时间内的发射功率的方式，调整发射功率，确保了电磁辐射能够始终处于安全的电磁辐射范围，保证了用户安全。In this way, for services (second services) with lower network requirements than the first service, the transmission power is adjusted directly by limiting the transmission power peak or limiting the transmission power within the average time, ensuring that the electromagnetic radiation can always be within a safe electromagnetic radiation range and ensuring user safety.
根据第一方面，或者以上第一方面的任意一种实现方式，调整第二业务对应的第二信道的第二发射功率，包括：以一步到位式调整方式，将第二发射功率调整至设定的发射功率峰值或设定的平均时间内对应的发射功率，设定的发射功率峰值和平均时间内对应的发射功率均小于发射功率限制值。According to the first aspect, or any implementation method of the first aspect above, the second transmission power of the second channel corresponding to the second service is adjusted, including: adjusting the second transmission power to a set transmission power peak value or a corresponding transmission power within a set average time in a one-step adjustment manner, and the set transmission power peak value and the corresponding transmission power within the average time are both less than the transmission power limit value.
由此，通过一步到位式调整方式，使得电磁辐射能够尽快降到安全的电磁辐射范围，保证了用户安全。Therefore, through a one-step adjustment method, electromagnetic radiation can be reduced to a safe electromagnetic radiation range as quickly as possible, ensuring user safety.
根据第一方面，或者以上第一方面的任意一种实现方式，在当前周期内，以第一目标发射功率，在第一信道中发射信号之前，方法还包括：确定第一信道是否是无线资源控制状态为业务态的物理随机接入信道PRACH；在第一信道不是业务态的PRACH时，确定第一业务对应的发射信号是否是信道探测参考信号SRS；在第一业务对应的发射信号不是SRS时，确定第一信道是否是物理上行链路控制信道PUCCH；在第一信道是PUCCH时，确定PUCCH中是否有调度请求SR信号；在PUCCH中没有SR信号时，确定PUCCH中是否有混合自动重传请求HARQ信号；在PUCCH中没有HARQ信号时，确定PUCCH中是否有用于衡量传输下行数据的第二信道状态信息；在PUCCH中没有第二信道状态信息时，执行在当前周期内，以第一目标发射功率，在第一信道中发射信号的步骤。According to the first aspect, or any implementation method of the first aspect above, within the current period, at the first target transmission power, before transmitting a signal in the first channel, the method also includes: determining whether the first channel is a physical random access channel PRACH with a wireless resource control state of a service state; when the first channel is not a PRACH in a service state, determining whether the transmission signal corresponding to the first service is a channel sounding reference signal SRS; when the transmission signal corresponding to the first service is not SRS, determining whether the first channel is a physical uplink control channel PUCCH; when the first channel is PUCCH, determining whether there is a scheduling request SR signal in the PUCCH; when there is no SR signal in the PUCCH, determining whether there is a hybrid automatic repeat request HARQ signal in the PUCCH; when there is no HARQ signal in the PUCCH, determining whether the PUCCH whether there is second channel state information for measuring the transmission of downlink data in the PUCCH; when there is no second channel state information in the PUCCH, executing the step of transmitting a signal in the first channel with the first target transmit power within the current period.
由此，在以第一目标发射功率发射信号前，通过进一步判断第一通道是否为处于特定状态，或者含有特定信号的重要信道，如PRACH，PUCCH等，进而在确定第一信道不是特定的重要信道时，才在当前周期内，以第一目标发射功率，在第一信道中发射信号，从而可以避免这些重要信道的发射功率被调整，进而保证了重要信道的业务能够正常进行。Therefore, before transmitting a signal with the first target transmission power, it is further determined whether the first channel is in a specific state, or is an important channel containing a specific signal, such as PRACH, PUCCH, etc., and only when it is determined that the first channel is not a specific important channel, the signal is transmitted in the first channel with the first target transmission power within the current cycle, thereby avoiding the transmission power of these important channels from being adjusted, thereby ensuring that the services of the important channels can proceed normally.

由此，在第一信道为特定的重要信道时，直接以第一信道当前支持的第一发射功率发射信息，从而保证了该信道对应的业务的正常进行。Therefore, when the first channel is a specific important channel, information is directly transmitted with the first transmission power currently supported by the first channel, thereby ensuring the normal operation of the service corresponding to the channel.
根据第一方面，或者以上第一方面的任意一种实现方式，方法还包括：在第一业务对应的发射信号是SRS时，在当前周期内，以第一发射功率，在第一信道中发射信号。According to the first aspect, or any implementation of the first aspect above, the method further includes: when the transmission signal corresponding to the first service is SRS, transmitting the signal in the first channel with the first transmission power within the current period.

由此，在第一信道为特定的重要信道时，直接以第一信道当前支持的第一发射功率发射信息，从而保证了该信道对应的业务的正常进行。Therefore, when the first channel is a specific important channel, information is directly transmitted with the first transmission power currently supported by the first channel, thereby ensuring the normal operation of the service corresponding to the channel.
根据第一方面，或者以上第一方面的任意一种实现方式，方法还包括：在PUCCH中有HARQ信号时，在当前周期内，以第一发射功率，在第一信道中发射信号。According to the first aspect, or any implementation of the first aspect above, the method further includes: when there is a HARQ signal in the PUCCH, transmitting the signal in the first channel with the first transmission power in the current cycle.
由此，在第一信道为特定的重要信道时，直接以第一信道当前支持的第一发射功率发射信息，从而保证了该信道对应的业务的正常进行。Therefore, when the first channel is a specific important channel, information is directly transmitted with the first transmission power currently supported by the first channel, thereby ensuring the normal operation of the service corresponding to the channel.
根据第一方面，或者以上第一方面的任意一种实现方式，方法还包括：在PUCCH中有第二信道状态信息时，在当前周期内，以第一发射功率，在第一信道中发射信号。According to the first aspect, or any implementation of the first aspect above, the method further includes: when there is second channel state information in the PUCCH, transmitting a signal in the first channel with the first transmission power within the current period.
由此，在第一信道为特定的重要信道时，直接以第一信道当前支持的第一发射功率发射信息，从而保证了该信道对应的业务的正常进行。Therefore, when the first channel is a specific important channel, information is directly transmitted with the first transmission power currently supported by the first channel, thereby ensuring the normal operation of the service corresponding to the channel.
第二方面，本申请提供一种发射功率的调整方法。该方法应用于电子设备，包括：在电子设备执行业务的过程中，按照设定周期获取电子设备当前执行的业务对应的信道的传输上行数据的信道状态信息；根据信道状态信息，确定信道在当前周期支持的发射功率；根据信道状态信息，确定信道在当前周期的功率回退值；根据发射功率、功率回退值和发射功率限制值，调整发射功率，发射功率限制值根据电子设备所在区域的电磁波吸收比值限制值确定；确定信道是否是无线资源控制状态为业务态的物理随机接入信道PRACH；在信道不是业务态的PRACH时，确定业务对应的发射信号是否是信道探测参考信号SRS；在业务对应的发射信号不是SRS时，确定信道是否是物理上行链路控制信道PUCCH；在信道是PUCCH时，确定PUCCH中是否有调度请求SR信号；在PUCCH中没有SR信号时，确定PUCCH中是否有混合自动重传请求HARQ信号；在PUCCH中没有HARQ信号时，确定PUCCH中是否有用于衡量传输下行数据的信道状态信息；在PUCCH中没有用于衡量传输下行数据的信道状态信息时，在当前周期内，以调整后的发射功率，在信道中发射信号；否则，在当前周期内，直接以信道在当前周期支持的发射功率，在信道中发射信号。In the second aspect, the present application provides a method for adjusting the transmission power. The method is applied to an electronic device, including: in the process of the electronic device executing a service, obtaining the channel state information of the uplink data transmitted by the channel corresponding to the service currently executed by the electronic device according to a set period; determining the transmission power supported by the channel in the current period according to the channel state information; determining the power backoff value of the channel in the current period according to the channel state information; adjusting the transmission power according to the transmission power, the power backoff value and the transmission power limit value, and the transmission power limit value is determined according to the electromagnetic wave absorption ratio limit value of the area where the electronic device is located; determining whether the channel is a physical random access channel PRACH with a wireless resource control state in a service state; when the channel is not a PRACH in a service state, determining whether the transmission signal corresponding to the service is a channel sounding reference signal SRS; When the transmission signal corresponding to the service is not SRS, determine whether the channel is the physical uplink control channel PUCCH; when the channel is PUCCH, determine whether there is a scheduling request SR signal in the PUCCH; when there is no SR signal in the PUCCH, determine whether there is a hybrid automatic repeat request HARQ signal in the PUCCH; when there is no HARQ signal in the PUCCH, determine whether there is channel state information for measuring the transmission of downlink data in the PUCCH; when there is no channel state information for measuring the transmission of downlink data in the PUCCH, transmit the signal in the channel with the adjusted transmission power in the current period; otherwise, transmit the signal in the channel directly with the transmission power supported by the channel in the current period in the current period.
这样，不考虑电子设备当前执行的业务具体为哪一类型的业务，在当前业务的整个作业过程中，均周期性地评估该业务对应的信道在当前周期内的发射功率和该周期内信道对应的功率回退值，进而根据发射功率、功率回退值，以及电子设备当前所在区域对应的发射功率限制值，动态调整发射功率，实现了对电子设备可执行的所有业务的动态调整。In this way, regardless of the specific type of service currently executed by the electronic device, during the entire operation process of the current service, the transmission power of the channel corresponding to the service in the current period and the power backoff value corresponding to the channel in the period are periodically evaluated, and then the transmission power is dynamically adjusted according to the transmission power, the power backoff value, and the transmission power limit value corresponding to the current area of the electronic device, thereby realizing dynamic adjustment of all services that can be executed by the electronic device.
此外，在根据调整后的发射功率在信道中发射信号前，通过进一步判断信道是否为处于业务态的PRACH，以及是否为没有传输SR信号、HARQ信号、用于衡量传输下行数据的信道状态信息的信道，在确定满足上述判断时，才根据调整后的发射功率在信道中发射信号，否则直接以当前信道支持的发射功率，在该信道中发射信号，即不调整发射功率。由此做到了既保证用户处于安全的电磁辐射范围，又能够兼顾最重要信道的发射功率需求，保证了重要信道的通信质量。In addition, before transmitting signals in the channel according to the adjusted transmit power, it is further determined whether the channel is a PRACH in service state, and whether it is a channel that does not transmit SR signals, HARQ signals, and channel state information used to measure downlink data transmission. Only when it is determined that the above judgments are met, the signal is transmitted in the channel according to the adjusted transmit power, otherwise the signal is directly transmitted in the channel with the transmit power supported by the current channel, that is, the transmit power is not adjusted. In this way, it is ensured that users are in a safe electromagnetic radiation range, and the transmit power requirements of the most important channels are taken into account, ensuring the communication quality of important channels.

随着通信技术和终端技术的发展，电子设备可以实现的功能越来越多。电子设备在为用户的日常生活和办公带来便利的同时，也让用户接触到了更多的电磁辐射。With the development of communication technology and terminal technology, electronic devices can realize more and more functions. While electronic devices bring convenience to users' daily life and office, they also expose users to more electromagnetic radiation.
由于电磁辐射会造成电磁污染，影响人体健康。目前为了降低电磁辐射，在一些可能的实现方式中，会通过采取电磁屏蔽措施的方式来减少电磁辐射能量，进而改善电磁环境。但是，由于电磁屏蔽措施的方式需要考虑材料，甚至需要在电子设备中增加额外的器件，因此实现成本相对较高。故而，在另一些可能的实现方式中，会在产品设计时，通过采取各类技术措施，从源头降低电磁辐射能量。Electromagnetic radiation can cause electromagnetic pollution and affect human health. At present, in order to reduce electromagnetic radiation, in some possible implementation methods, electromagnetic shielding measures are taken to reduce electromagnetic radiation energy and thus improve the electromagnetic environment. However, since electromagnetic shielding measures need to consider materials and even need to add additional devices to electronic devices, the implementation cost is relatively high. Therefore, in other possible implementation methods, various technical measures are taken during product design to reduce electromagnetic radiation energy from the source.
关于从源头降低电磁辐射能量的方式，例如可以通过调整电磁波吸收比值(Specific Absorption Rate，SAR)来实现。Regarding ways to reduce electromagnetic radiation energy from the source, for example, it can be achieved by adjusting the electromagnetic wave absorption ratio (Specific Absorption Rate, SAR).
需要说明的是，SAR是一个标准量，用来测量人体组织对手机等电子设备产生的电磁能量的吸收。SAR的单位是W/Kg(瓦/千克)。SAR越大，电磁辐射对用户的影响越大；反之则影响较小。It should be noted that SAR is a standard quantity used to measure the absorption of electromagnetic energy generated by mobile phones and other electronic devices by human tissue. The unit of SAR is W/Kg (watt/kilogram). The larger the SAR, the greater the impact of electromagnetic radiation on the user; otherwise, the impact is smaller.
此外，还需要说明的是，由于手机、平板等电子设备在进入市场时，需要满足当地的法律法规标准，如产品进入中国市场时需要进行中国强制认证(China Compulsory Certification，CCC)，产品进入欧洲市场时需要进行欧洲统一(ConformiteEuropeenne，CE)认证，产品进入美国市场时需要进行美国联邦通信委员会(Federal Communication Commission，FCC)认证。而不同的国家和地区都制定了相应的强制管理要求，并设置了SAR限制值。其中，SAR限制值是指6分钟内，每千克人体组织最多被允许吸收的电磁波辐射量(电磁能量)。In addition, it should be noted that when mobile phones, tablets and other electronic devices enter the market, they need to meet local laws, regulations and standards. For example, when products enter the Chinese market, they need to undergo China Compulsory Certification (CCC), when products enter the European market, they need to undergo Conformite Europeenne (CE) certification, and when products enter the US market, they need to undergo Federal Communications Commission (FCC) certification. Different countries and regions have formulated corresponding mandatory management requirements and set SAR limit values. Among them, the SAR limit value refers to the maximum amount of electromagnetic wave radiation (electromagnetic energy) allowed to be absorbed per kilogram of human tissue within 6 minutes.
对于不同的国家和地区，由于其设置管理要求(衡量标准)不同，故而SAR限制值也有所不同。例如，对于美国，其采用的衡量标准为以1克(g)为质量单位，设置的SAR限制值为1.6W/Kg；对于欧盟和中国，其采用的衡量标准为以10g为质量单位，设置的SAR限制值为2.0W/Kg。即，电子设备在进入不同的市场时，实际的SAR不超过该地区设置的SAR限制值即可。Different countries and regions have different management requirements (measurement standards) and therefore different SAR limits. For example, the United States uses 1 gram (g) as the mass unit, and the SAR limit is set at 1.6W/Kg; the European Union and China use 10g as the mass unit, and the SAR limit is set at 2.0W/Kg. That is, when electronic devices enter different markets, the actual SAR does not exceed the SAR limit set in that region.
举例来说，在用户将手机这一电子设备靠近头部的场景下，当电子设备使用功率值为P的发射功率，通过电子设备的天线(如图4中示出的天线1)发射信号时，其测试结果的SAR分布图可如图1所示。For example, in a scenario where a user holds a mobile phone, an electronic device, close to his head, when the electronic device uses a transmission power with a power value of P to transmit a signal through the antenna of the electronic device (antenna 1 shown in Figure 4), the SAR distribution diagram of the test results may be as shown in Figure 1.
以颜色越深的区域，SAR越大，其电磁辐射也越大为例。在图1所示的SAR分布图，区域1中的SAR最大。因此，只要保证区域1的SAR不超过该地区的SAR限制值，就可以保证图1所示场景(用户将手机这一电子设备靠近头部的场景)下，电子设备的天线使用P的发射功率发射信号符合该地区针对SAR的法规要求。For example, the darker the area, the greater the SAR and the greater the electromagnetic radiation. In the SAR distribution diagram shown in Figure 1, the SAR in area 1 is the largest. Therefore, as long as the SAR in area 1 does not exceed the SAR limit value of the area, it can be guaranteed that in the scenario shown in Figure 1 (the user holds the mobile phone, an electronic device, close to the head), the antenna of the electronic device uses a transmission power of P to transmit signals that meet the regulatory requirements for SAR in the area.
基于此可知，从源头降低电磁辐射能量的方式，具体可以通过降低电磁波吸收比值(Specific Absorption Rate，SAR)来实现。而SAR的降低，则可以通过调整天线的发射功率实现。即，通过调整天线的发射功能，可以达到降低电子设备的电磁辐射的效果。但是，降低天线的发射功率，可能会带来通信质量的降低，而目前为了提升网络的上行覆盖和速率，运营商在多个频段提出了高功率(高发射功率)电子设备的标准化需求。因此，当电子设备的发射功率上升后，若上下行资源配比不合适，就会导致SAR无法满足区域要求，即无法降低SAR，进而无法降低电磁辐射，影响人体健康。Based on this, we can know that the way to reduce electromagnetic radiation energy from the source can be achieved by reducing the electromagnetic wave absorption ratio (Specific Absorption Rate, SAR). The reduction of SAR can be achieved by adjusting the transmission power of the antenna. That is, by adjusting the transmission function of the antenna, the effect of reducing the electromagnetic radiation of electronic equipment can be achieved. However, reducing the transmission power of the antenna may lead to a decrease in communication quality. At present, in order to improve the uplink coverage and rate of the network, operators have put forward standardized requirements for high-power (high transmission power) electronic equipment in multiple frequency bands. Therefore, when the transmission power of electronic equipment increases, if the uplink and downlink resource ratio is not appropriate, it will cause SAR to fail to meet regional requirements, that is, SAR cannot be reduced, and electromagnetic radiation cannot be reduced, which affects human health.
因此，如何合理调整天线的发射功率，从而既可确保用户处于安全的电磁辐射范围，又不影响用户体验是目前亟需解决的问题。Therefore, how to reasonably adjust the antenna's transmission power to ensure that users are within a safe electromagnetic radiation range without affecting the user experience is a problem that needs to be solved urgently.
目前，在一些可能的实现方式中，会通过限制发射功率峰值(Peak Tx Power)，或者限制平均时间内的发射功率(time average power)的方式控制电子设备上行发射功率，从而达到降低SAR，以使用户处于安全的电磁辐射范围。Currently, in some possible implementation methods, the uplink transmission power of electronic devices is controlled by limiting the peak transmission power (Peak Tx Power) or limiting the transmission power in average time (time average power), so as to reduce SAR and keep users within a safe electromagnetic radiation range.
如图2A所示，在“07：35.3”至“08：30.3”这一时间范围内，如果当前使用场景对应的SAR的法规要求对应的最大发射功率(PLimit)为16。基于上述限制方式，为了确保发射功率能够始终小于PLimit，会设置一个小于PLimit的发射功率峰值，比如介于14～16之间，如15，则在该时间范围内，电子设备只能以15的发射功率发射信号。As shown in FIG2A , within the time range of “07:35.3” to “08:30.3”, if the maximum transmission power (PLimit) corresponding to the SAR regulatory requirements of the current usage scenario is 16. Based on the above restriction method, in order to ensure that the transmission power can always be less than PLimit, a transmission power peak value less than PLimit is set, such as between 14 and 16, such as 15. In this time range, the electronic device can only transmit signals at a transmission power of 15.
继续参见图2A，示例性的，如果在“08：30.3”这一时刻后，至“09：30.1”这一时刻，使用场景对应的SAR的法规要求发生了变化，为了满足该场景下对应的SAR的法规要求，发射功率峰值需要从15调整为10，具体为电子设备直接从使用15的发射功率发射信号变为使用10的发射功率发射信号。Continuing to refer to FIG. 2A , for example, if the regulatory requirements for SAR corresponding to the usage scenario change after the moment “08:30.3” to the moment “09:30.1”, in order to meet the regulatory requirements for SAR corresponding to the scenario, the peak transmission power needs to be adjusted from 15 to 10. Specifically, the electronic device directly changes from transmitting signals using a transmission power of 15 to transmitting signals using a transmission power of 10.
应当理解地是，上述说明仅是为了更好地理解本实施例的技术方案而列举的示例，不作为对本实施例的唯一限制。限制平均时间内的发射功率的实现方式与此类似，此处不再赘述。It should be understood that the above description is only an example for better understanding the technical solution of this embodiment, and is not the only limitation to this embodiment. The implementation method of limiting the transmit power within the averaging time is similar to this, and will not be repeated here.
通过上述示例可知，这种调整发射功率的方式，虽然可以达到降低SAR，以使用户处于安全的电磁辐射范围。但是，会导致发射功率骤降，进而导致电子设备当前进行的业务出现卡顿，电子设备的界面出现花屏，严重影响用户体验。From the above examples, we can see that this method of adjusting the transmit power can reduce SAR to keep users within a safe electromagnetic radiation range. However, it will cause a sudden drop in transmit power, which will cause the current services of the electronic device to freeze and the interface of the electronic device to become distorted, seriously affecting the user experience.
此外，上述调整发射功率的方式中设置的发射功率峰值或者限制平均时间内的发射功率，一旦设置后，对所有信道都起作用。这就导致部分重要的信道，如轮发信道探测参考信号(Sounding Reference Signal，SRS)的信道，发射的SRS受到影响，进而无法完成对应的业务。In addition, the peak transmit power or the transmit power within the limited average time set in the above-mentioned method of adjusting transmit power, once set, will be effective for all channels. This will cause some important channels, such as the channel that transmits the channel sounding reference signal (SRS) in turn, to be affected in transmitting SRS, and thus the corresponding services cannot be completed.
如图2B所示，在N41频率的SRS需要以15，甚至15以上，如20的发射功率轮发SRS时，如果电子设备当前使用场景或所处地区对应的SAR的法规要求限制PLimit为14。基于上述限制方式，为了确保发射功率能够始终小于PLimit，会设置一个小于PLimit的发射功率峰值，比如10。那么在“17：18.0”至“17：34.1”这一时间段内，电子设备将一直按照10的发射功率轮发SRS，这就导致电子设备无法基于SRS完成对应的业务，如估计上行信道频域信息，做频率选择性调度；以及，无法用于估计下行信道，做下行波束赋形。As shown in FIG2B , when the SRS of the N41 frequency needs to be transmitted in rotation at a transmission power of 15, or even higher than 15, such as 20, if the SAR regulations corresponding to the current usage scenario of the electronic device or the area in which it is located require to limit PLimit to 14. Based on the above restriction method, in order to ensure that the transmission power can always be less than PLimit, a transmission power peak value less than PLimit will be set, such as 10. Then, in the time period from "17:18.0" to "17:34.1", the electronic device will continue to transmit the SRS at a transmission power of 10, which makes it impossible for the electronic device to complete the corresponding services based on the SRS, such as estimating the frequency domain information of the uplink channel and performing frequency selective scheduling; and it cannot be used to estimate the downlink channel and perform downlink beamforming.
应当理解地是，上述说明仅是为了更好地理解本实施例的技术方案而列举的示例，不作为对本实施例的唯一限制。限制平均时间内的发射功率的实现方式与此类似，此处不再赘述。It should be understood that the above description is only an example for better understanding the technical solution of this embodiment, and is not the only limitation to this embodiment. The implementation method of limiting the transmit power within the averaging time is similar to this, and will not be repeated here.
有鉴于此，本申请实施例提供了一种发射功率的调整方法，通过确定当前业务场景对通信质量的要求，进而根据不同业务场景对通信质量的要求，在整个业务过程中周期性评估发射功率，并采用小步长的方式控制上行最大发射功率，从而避免了用户体验的突然变差，使用户体验变化过程更加平滑，做到了既不影响用户体验，又可确保用户处于安全的电磁辐射范围。In view of this, an embodiment of the present application provides a method for adjusting the transmission power. By determining the requirements of the current business scenario for communication quality, and then according to the requirements of different business scenarios for communication quality, the transmission power is periodically evaluated during the entire business process, and the maximum uplink transmission power is controlled in a small step size, thereby avoiding a sudden deterioration in user experience and making the user experience change process smoother, thereby achieving the goal of not affecting the user experience and ensuring that the user is within a safe electromagnetic radiation range.

所谓uRLLC，即高可靠低时延通信(Ultra-reliable and Low Latency Communication)，它负责核心关注网络的高可靠性和超低时延，即具备高可靠性和超低时延的网络特性，在实际应用中主要针对音视频通话/会议，语音通话等业务。The so-called uRLLC, namely Ultra-reliable and Low Latency Communication, is responsible for the high reliability and ultra-low latency of the network, that is, the network characteristics of high reliability and ultra-low latency. In actual applications, it is mainly aimed at audio and video calls/conferences, voice calls and other services.
所谓mMTC，即海量机器通信(Massive MachineType Communication)，它具有巨大的连接数量，以支持海量物联网设备的网络特性，在实际应用中主要针对物联网(Internet of Things，简称IoT)设备。The so-called mMTC, namely Massive Machine Type Communication, has a huge number of connections to support the network characteristics of massive IoT devices. In practical applications, it is mainly aimed at IoT (Internet of Things) devices.
此外，应当理解的，上述所说的IoT设备，例如可以是智能音响、冰箱、空调、电视等各种可以接入5G无线网络的智能设备。In addition, it should be understood that the IoT devices mentioned above can be, for example, smart speakers, refrigerators, air conditioners, televisions and other smart devices that can access the 5G wireless network.
基于上述对三大核心应用场景的描述，具体到本实施例中，第一业务具体为上述eMBB和/或uRLLC场景下的业务。第二业务为mMTC场景下的业务。Based on the above description of the three core application scenarios, specifically in this embodiment, the first service is specifically a service in the above eMBB and/or uRLLC scenario. The second service is a service in the mMTC scenario.
示例性的，在一些可能的实现方式中，第一业务例如为语音通话业务、音视频通话/会议业务、直播业务、游戏业务等。第二业务例如为对智能家居的控制业务。Exemplarily, in some possible implementations, the first service is, for example, a voice call service, an audio and video call/conference service, a live broadcast service, a game service, etc. The second service is, for example, a smart home control service.
关于第一业务和第二业务的识别，在一些可能的实现方式中，例如可以是通过获取电子设备当前产生的数据流。然后通过对数据流进行业务识别，进而确定该数据流来自哪一应用。接着，在确定提供该数据流的应用后，通过根据该应用的属性便可以确定该应用对应的业务所关注的网络特性。最终，通过判断该业务关注的网络特性便可以确定当前的业务是第一业务，还是第二业务。Regarding the identification of the first service and the second service, in some possible implementations, for example, the data stream currently generated by the electronic device can be obtained. Then, the service of the data stream is identified to determine which application the data stream comes from. Then, after determining the application providing the data stream, the network characteristics of the service corresponding to the application can be determined based on the attributes of the application. Finally, by judging the network characteristics of the service, it can be determined whether the current service is the first service or the second service.
通过上述对eMBB、uRLLC、mMTC这三种核心应用的网络特性的描述可知，在第一业务为eMBB和/或uRLLC场景下的业务，第二业务为mMTC场景下的业务时，第一业务关注的网络特性和第二业务关注的网络特性是不相同的。具体为，第一业务关注eMBB和/或uRLLC的网络特性，第二业务关注mMTC的网络特性。基于此，在根据提供数据流的应用的属性，确定该应用对应的业务所关注的网络特性后，通过确定当前业务所关注的网络特性是满足eMBB和/或uRLLC的网络特性，还是满足mMTC的网络特性，便可以快速确定当前业务是第一业务，还是第二业务。Through the above description of the network characteristics of the three core applications of eMBB, uRLLC, and mMTC, it can be known that when the first service is a service in the eMBB and/or uRLLC scenario, and the second service is a service in the mMTC scenario, the network characteristics that the first service focuses on and the network characteristics that the second service focuses on are different. Specifically, the first service focuses on the network characteristics of eMBB and/or uRLLC, and the second service focuses on the network characteristics of mMTC. Based on this, after determining the network characteristics that the service corresponding to the application focuses on according to the attributes of the application that provides the data stream, by determining whether the network characteristics that the current service focuses on meet the network characteristics of eMBB and/or uRLLC, or meet the network characteristics of mMTC, it is possible to quickly determine whether the current service is the first service or the second service.
示例性的，在当前业务所关注的网络特性满足eMBB和/或uRLLC的网络特性时，确定当前业务为第一业务。Exemplarily, when the network characteristics concerned by the current service meet the network characteristics of eMBB and/or uRLLC, the current service is determined to be the first service.
示例性的，在当前业务所关注的网络特性满足mMTC的网络特性时，确定当前业务为第二业务。Exemplarily, when the network characteristics concerned by the current service meet the network characteristics of mMTC, the current service is determined to be the second service.
应当理解地是，上述说明仅是为了更好地理解本实施例的技术方案而列举的示例，不作为对本实施例的唯一限制。It should be understood that the above description is merely an example listed for a better understanding of the technical solution of this embodiment, and is not intended to be the sole limitation to this embodiment.
此外，需要说明的是，关于业务类型的划分，在实际应用中可以根据实际的业务需求进行划分，本实施例对此不作限制。In addition, it should be noted that the classification of service types can be carried out according to actual service requirements in practical applications, and this embodiment does not impose any limitation on this.
此外，还需要说明的是，具体到本实施例中，对于第一业务采用的是一种发射功率的调整方式(后续称为调整方式1)，如步骤102至步骤105所示方式；对于第二业务采用的是另一种发射功率的调整方式(后续称为调整方式2)，如步骤107所示的方式，即图2A和图2B所示实施例中描述的限制发射功率峰值或限制平均时间内的发射功率的方式。In addition, it should be noted that, specifically in this embodiment, a transmission power adjustment method (hereinafter referred to as adjustment method 1) is adopted for the first service, as shown in steps 102 to 105; another transmission power adjustment method (hereinafter referred to as adjustment method 2) is adopted for the second service, as shown in step 107, that is, the method of limiting the transmission power peak or limiting the transmission power within the average time described in the embodiments shown in Figures 2A and 2B.
基于此，在确定当前业务为第一业务时，将执行步骤102。反之，在确定当前业务为第二业务时，则执行步骤108。Based on this, when it is determined that the current service is the first service, step 102 is executed. On the contrary, when it is determined that the current service is the second service, step 108 is executed.
102，在第一业务的作业过程中，按照设定周期获取第一业务对应的第一信道的传输上行数据的第一信道状态信息。102. During the operation of the first service, first channel state information of uplink data transmission of a first channel corresponding to the first service is obtained according to a set period.
为了便于说明，本实施例将第一业务对应的信道称为第一信道，第二业务对应的信道称为第二信道。然在实际应用中，基于不同的复用方式，如频分复用、时分复用、码分复用等，同一信道既可以发送第一业务对应的发射信号(射频信号)，也可以发送第二业务对应的发射信号(射频信号)。故而，在一些可能的实现方式中，第一信道和第二信道可以为同一信道。即，“第一”信道和“第二”信道仅用于区别不同业务对应的信道，不对信道本身构成限定。For ease of explanation, in this embodiment, the channel corresponding to the first service is referred to as the first channel, and the channel corresponding to the second service is referred to as the second channel. However, in actual applications, based on different multiplexing methods, such as frequency division multiplexing, time division multiplexing, code division multiplexing, etc., the same channel can send both the transmission signal (RF signal) corresponding to the first service and the transmission signal (RF signal) corresponding to the second service. Therefore, in some possible implementations, the first channel and the second channel can be the same channel. That is, the "first" channel and the "second" channel are only used to distinguish the channels corresponding to different services, and do not constitute a limitation on the channel itself.
关于上述所说的设定周期，例如为第一业务对应的发射周期，也可以为根据业务需求设置的固定周期，本实施例对此不作限制。The setting period mentioned above, for example, the transmission period corresponding to the first service, may also be a fixed period set according to service requirements, and this embodiment does not impose any limitation on this.
此外，关于上述所说的第一信道状态信息，具体为也用于衡量第一信道传输上行数据时，第一信道情况的信道信息，即通常所说的CSI(Channel State Information)。In addition, the first channel state information mentioned above is specifically channel information used to measure the condition of the first channel when the first channel transmits uplink data, which is commonly referred to as CSI (Channel State Information).
示例性的，在一些可能的实现方式中，该第一信道状态信息例如可以包括第一信道中的通信信号强度和干扰信号强度等信息。Exemplarily, in some possible implementations, the first channel state information may include, for example, information such as communication signal strength and interference signal strength in the first channel.
应当理解地是，上述说明仅是为了更好地理解本实施例的技术方案而列举的示例，不作为对本实施例的唯一限制。It should be understood that the above description is merely an example listed for a better understanding of the technical solution of this embodiment, and is not intended to be the sole limitation to this embodiment.
103，根据第一信道状态信息，确定第一信道在当前周期支持的第一发射功率。103. Determine, according to the first channel state information, a first transmit power supported by the first channel in a current period.
示例性的，在第一信道状态信息为上述所说的第一信道中的通信信号强度和干扰信号强度等信息时，第一发射功率的确认即为根据第一信道中的通信信号强度和干扰信号强度等信息确定。Exemplarily, when the first channel state information is the communication signal strength and interference signal strength in the first channel mentioned above, the confirmation of the first transmit power is determined based on the communication signal strength and interference signal strength in the first channel.
此外，需要说明的是，关于第一信道状态信息，以及后续所说的第二信道状态信息、信道状态信息等，均为电子设备中的Modem获取，然后上报给AP测的发射功率调整模块的。In addition, it should be noted that the first channel state information, as well as the second channel state information and channel state information mentioned later, are all acquired by the Modem in the electronic device and then reported to the transmit power adjustment module measured by the AP.
104，根据第一信道状态信息，确定第一信道在当前周期的功率回退值。104. Determine a power backoff value of the first channel in a current period according to the first channel state information.
示例性的，在一些可能的实现方式中，可以先根据第一信道状态信息，确定第一信道在当前周期的上行调度率。然后根据上行调度率，确定第一信道在当前周期的上行占比。最后根据上行占比，确定第一信道在当前周期的功率回退值。Exemplarily, in some possible implementations, the uplink scheduling rate of the first channel in the current cycle may be determined based on the first channel state information. Then, the uplink proportion of the first channel in the current cycle may be determined based on the uplink scheduling rate. Finally, the power backoff value of the first channel in the current cycle may be determined based on the uplink proportion.
所谓上行占比，指的是基站为电子设备进行传输资源配置时，上行信息的传输资源对应的时长在一个时间窗中的比例。一个时间窗包含若干单位信息传输时间，时间窗可以是任一时间长度，本申请对时间窗的时长不作具体限制。The so-called uplink ratio refers to the proportion of the duration of the uplink information transmission resources in a time window when the base station configures transmission resources for electronic devices. A time window contains several units of information transmission time, and the time window can be of any time length. This application does not impose specific restrictions on the duration of the time window.
此外，还需要说明的是，基站在为电子设备配置传输资源时，可以配置上行信息(上行数据/内容)的传输资源和下行信息的传输资源。In addition, it should be noted that when the base station configures transmission resources for the electronic device, it can configure transmission resources for uplink information (uplink data/content) and transmission resources for downlink information.
例如，上行占比为100％，表示在一个时间窗内，100％的时域资源被配置为上行信息的传输资源。又例如，上行占比为50％，表示在一个时间窗内，50％的时域资源被配置为上行信息的传输资源。For example, an uplink proportion of 100% means that within a time window, 100% of the time domain resources are configured as transmission resources for uplink information. For another example, an uplink proportion of 50% means that within a time window, 50% of the time domain resources are configured as transmission resources for uplink information.
此外，还需要说明的是，不同的通信系统中，单位信息传输时间可以不相同。例如，在长期演进(long term evolution，LTE)通讯系统中，单位信息传输时间可以是一个子帧(subframe)。在新的无线接入方式(New Radio，NR)，如5G通讯系统中，单位信息传输时间可以是一个时隙(slot)，一个迷你时隙(mini-slot)，或一个符号(symbol)等。In addition, it should be noted that the unit information transmission time may be different in different communication systems. For example, in the long term evolution (LTE) communication system, the unit information transmission time may be a subframe. In the new radio access method (NR), such as the 5G communication system, the unit information transmission time may be a slot, a mini-slot, or a symbol.
此外，还需要说明的是，在一些可能的实现方式中，当一电子设备与其他电子设备进行通信交互，以实现数据传输时，上行占比指的是该电子设备的发射时长在一个时间窗口中的比例。例如，上行占比100％，表示在一个时间窗内，100％的时域资源被配置为发送信息。又例如，上行占比为50％，表示在一个时间窗内，50％的时域资源被配置为发送信息。In addition, it should be noted that in some possible implementations, when an electronic device communicates and interacts with other electronic devices to achieve data transmission, the uplink ratio refers to the proportion of the transmission time of the electronic device in a time window. For example, an uplink ratio of 100% means that within a time window, 100% of the time domain resources are configured to send information. For another example, an uplink ratio of 50% means that within a time window, 50% of the time domain resources are configured to send information.
应当理解地是，上述说明仅是为了更好地理解本实施例的技术方案而列举的示例，不作为对本实施例的唯一限制。It should be understood that the above description is merely an example listed for a better understanding of the technical solution of this embodiment, and is not intended to be the sole limitation to this embodiment.
此外，关于上述所说的功率回退值，指的是在当前信道，如第一信道支持的最大发射功率，即上述所说的第一发射功率的基础上，需要回退的功率值。In addition, the power backoff value mentioned above refers to the power value that needs to be backed off based on the maximum transmission power supported by the current channel, such as the first channel, that is, the first transmission power mentioned above.
105，根据第一发射功率、功率回退值和发射功率限制值，确定第一目标发射功率。105. Determine a first target transmit power according to the first transmit power, the power backoff value, and the transmit power limit value.
示例性的，本实施例中所说的发射功率限制值具体为根据电子设备当前所在区域的电磁波吸收比值限制值，即上述实施例中所说的SAR限制值确定的。Exemplarily, the transmission power limit value in this embodiment is specifically determined according to the electromagnetic wave absorption ratio limit value of the area where the electronic device is currently located, that is, the SAR limit value mentioned in the above embodiment.
具体到本实施例中，为了既确保用户能够处于安全的电磁辐射范围，又能保证通信质量，进而保障用户使用体验。在根据第一发射功率、功率回退值和发射功率限制值，确定第一目标发射功率时，会先判断第一发射功率与发射功率限制值的大小关系，进而决定是否在第一发射功率的基础上回退确定的功率回退值。Specifically in this embodiment, in order to ensure that the user can be in a safe electromagnetic radiation range and to ensure the communication quality, thereby protecting the user experience, when determining the first target transmit power according to the first transmit power, the power backoff value and the transmit power limit value, the magnitude relationship between the first transmit power and the transmit power limit value is first determined, and then a decision is made as to whether to backoff the determined power backoff value based on the first transmit power.
具体地，在第一发射功率大于发射功率限制值时，发射功率调整模块可控制第一发射功率，回退通过上述方式确定的功率回退值，进而得到第一目标发射功率。Specifically, when the first transmit power is greater than the transmit power limit value, the transmit power adjustment module may control the first transmit power to back off the power back-off value determined in the above manner, thereby obtaining the first target transmit power.
需要说明的是，在第一发射功率基础上回退上述功率回退值后得到的第一目标发射功率，小于发射功率限制值，从而确保用户能够处于安全的电磁辐射范围。It should be noted that the first target transmit power obtained after backing off the power back-off value on the basis of the first transmit power is less than the transmit power limit value, thereby ensuring that the user can be within a safe electromagnetic radiation range.
此外，在控制第一发射功率，回退上述所说的功率回退值，得到第一目标发射功率的过程中，为了避免用户体验突然变差，可根据功率回退值确定一个小于功率回退值的发射功率调整步长。然后再根据这个小步长的发射功率调整步长，在当前周期内，控制第一发射功率逐步回退，直至回退功率回退值，这样就可以得到第一目标发射功率。In addition, in the process of controlling the first transmit power, backing off the power backoff value mentioned above, and obtaining the first target transmit power, in order to avoid a sudden deterioration of the user experience, a transmit power adjustment step size smaller than the power backoff value can be determined according to the power backoff value. Then, according to the transmit power adjustment step size with a small step size, the first transmit power is controlled to be gradually backed off in the current cycle until the power backoff value is backed off, so that the first target transmit power can be obtained.
示例性的，在一些可能的实现方式中，该小步长的发射功率调整步长，例如是根据功率回退值和当前周期的时长确定的。即，发射功率调整步长为单位时间对应的功率均值。Exemplarily, in some possible implementations, the small-step transmission power adjustment step is determined, for example, according to the power backoff value and the duration of the current cycle, that is, the transmission power adjustment step is the power mean value corresponding to a unit time.
示例性的，相较于图2A，图7中以调整方式1对第一发射功率进行调整，可以在“08：30.3”至“09：04.9”这一周期内，以每次回退1功率的步长，逐步将发射功率从15回退到10。这样，在基于发射功率调整步长调整发射功率时，可以匀速降低发射功率，使得用户体验过程更加平滑。Exemplarily, compared with FIG. 2A , FIG. 7 adjusts the first transmit power in adjustment mode 1, and can gradually reduce the transmit power from 15 to 10 in a period from “08:30.3” to “09:04.9” with a step size of 1 power each time. In this way, when adjusting the transmit power based on the transmit power adjustment step size, the transmit power can be uniformly reduced, making the user experience process smoother.
此外，还需要说明的是，在另一些可能的实现方式中，在第一发射功率不大于发射功率限制值时，可以直接将第一发射功率作为第一目标发射功率。即，不对第一信道在当前周期内支持的第一发射功率进行调整，直接以第一信道在当前周期内支持的最大发射功率(第一发射功率)发射信号即可。In addition, it should be noted that in some other possible implementations, when the first transmit power is not greater than the transmit power limit value, the first transmit power can be directly used as the first target transmit power. That is, the first transmit power supported by the first channel in the current period is not adjusted, and the signal can be directly transmitted at the maximum transmit power (first transmit power) supported by the first channel in the current period.
由此，在第一发射功率不大于发射功率限制值的情况下，即便根据第一信道状态信息确定的了功率回退值，也可以不对第一发射功率进行调整，而是直接以第一发射功率发射信号，这样在确保用户处于安全的电磁辐射范围的情况下，又能够使电子设备当前有一个较高的发射功率，保证了通信质量，进而保证了用户使用体验。Therefore, when the first transmit power is not greater than the transmit power limit value, even if the power backoff value is determined according to the first channel state information, the first transmit power may not be adjusted, but the signal may be directly transmitted at the first transmit power. In this way, while ensuring that the user is in a safe electromagnetic radiation range, the electronic device can currently have a higher transmit power, thereby ensuring the communication quality and further ensuring the user experience.
106，在当前周期内，以第一目标发射功率，在第一信道中发射信号。106. In a current cycle, transmit a signal in a first channel at a first target transmit power.
具体地，AP中的发射功率调整模块在按照调整方式1，对第一发射功率进行调整，得到第一目标发射功率后，会通知Modem在当前周期内，以第一目标发射功率，在第一信道中发射信号。Specifically, after the transmit power adjustment module in the AP adjusts the first transmit power according to adjustment mode 1 and obtains the first target transmit power, it notifies the Modem to transmit signals in the first channel at the first target transmit power in the current cycle.
107，在第二业务的作业过程中，采用限制发射功率峰值或限制平均时间内的发射功率的方式，调整第二业务对应的第二信道的第二发射功率。107. During the operation of the second service, the peak value of the transmission power is limited or the transmission time within the average time is limited. The second transmit power of the second channel corresponding to the second service is adjusted in a transmit power manner.
通过上述图2A和图2B所示实施例的描述部分可知，在采用限制发射功率峰值或限制平均时间内的发射功率的方式，调整第二业务对应的第二信道的第二发射功率时，具体是直接将第二发射功率降低到预先设定的低于发射功率限制值的发射功率峰值，即以一步到位式调整方式，将第二发射功率调整至设定的发射功率峰值或设定的平均时间内对应的发射功率，设定的发射功率峰值和平均时间内对应的发射功率均小于发射功率限制值。It can be seen from the description part of the embodiments shown in Figures 2A and 2B above that when the second transmit power of the second channel corresponding to the second service is adjusted by limiting the transmit power peak value or limiting the transmit power within the average time, the second transmit power is specifically directly reduced to a preset transmit power peak value that is lower than the transmit power limit value, that is, the second transmit power is adjusted to the set transmit power peak value or the corresponding transmit power within the set average time in a one-step adjustment manner, and the set transmit power peak value and the corresponding transmit power within the average time are both less than the transmit power limit value.
需要说明的是，关于发射功率峰值，例如为在当前支持的发射功率基础上回退对应的功率回退值后得到的。即，对于这种方式，不考虑第二信道当前支持的第二发射功率与发射功率限制值之间的关系。不管第二发射功率是大于发射功率限制值，还是不大于发射功率限制值，均在第二发射功率的基础上，以一步到位式调整方式，将第二发射功率回退确定的功率回退值。It should be noted that, regarding the transmit power peak value, for example, it is obtained after backing off the corresponding power backoff value based on the currently supported transmit power. That is, for this method, the relationship between the second transmit power currently supported by the second channel and the transmit power limit value is not considered. Regardless of whether the second transmit power is greater than the transmit power limit value or not greater than the transmit power limit value, the second transmit power is backed off to the determined power backoff value in a one-step adjustment manner based on the second transmit power.
关于采用限制发射功率峰值或限制平均时间内的发射功率的方式，调整第二业务对应的第二信道的第二发射功率的实现细节，未在本实施例示出的部分，可以参见图2A和图2B所示实施例的描述部分，此处不再赘述。Regarding the implementation details of adjusting the second transmission power of the second channel corresponding to the second service by limiting the transmission power peak or limiting the transmission power within the average time, the parts not shown in this embodiment can be referred to the description part of the embodiments shown in Figures 2A and 2B, and will not be repeated here.
108，根据调整后的第二发射功率，在第二通道发射信号。108. Transmit a signal on the second channel according to the adjusted second transmission power.
由此，通过识别当前的业务场景是否为增强型移动带宽和/或高可靠低时延通信的第一业务，进而在确定当前业务为第一业务时，在第一业务的整个作业过程中周期性地评估第一业务对应的第一信道在当前周期内的第一发射功率和该周期内第一信道对应的功率回退值，进而根据第一发射功率、功率回退值，以及电子设备当前所在区域对应的发射功率限制值，动态调整第一发射功率，以获得适合该周期的第一目标发射功率，最终以第一目标发射功率，在第一信道中发射信号，从而使得第一业务的整个作业过程，不仅能够以合适的发射功率发射信号，保证通信质量，同时又可以确保用户处于安全的电磁辐射范围。Therefore, by identifying whether the current service scenario is the first service of enhanced mobile bandwidth and/or high-reliability and low-latency communication, and then when it is determined that the current service is the first service, the first transmission power of the first channel corresponding to the first service in the current cycle and the power backoff value corresponding to the first channel in the cycle are periodically evaluated during the entire operation process of the first service, and then the first transmission power is dynamically adjusted according to the first transmission power, the power backoff value, and the transmission power limit value corresponding to the current area of the electronic device to obtain the first target transmission power suitable for the cycle, and finally the signal is transmitted in the first channel with the first target transmission power, so that the entire operation process of the first service can not only transmit signals with appropriate transmission power to ensure communication quality, but also ensure that users are in a safe electromagnetic radiation range.
参见图8，示例性示出一种由AP侧和Modem侧配合实现的发射功率的调整进行方法，具体包括图6所述实施例中的步骤101至步骤208，以及在Modem中实现的步骤201至步骤206。8 , a method for adjusting transmit power implemented by cooperation between the AP side and the Modem side is exemplified, specifically including steps 101 to 208 in the embodiment described in FIG. 6 , and steps 201 to 206 implemented in the Modem.
101，识别当前的业务是第一业务，还是第二业务。101, identifying whether the current service is the first service or the second service.
102，在第一业务的作业过程中，按照设定周期获取第一业务对应的第一信道的传输上行数据的第一信道状态信息。102. During the operation of the first service, first channel state information of uplink data transmission of a first channel corresponding to the first service is obtained according to a set period.
103，根据第一信道状态信息，确定第一信道在当前周期支持的第一发射功率。103. Determine, according to the first channel state information, a first transmit power supported by the first channel in a current period.
104，根据第一信道状态信息，确定第一信道在当前周期的功率回退值。104. Determine a power backoff value of the first channel in a current period according to the first channel state information.
105，根据第一发射功率、功率回退值和发射功率限制值，确定第一目标发射功率。105. Determine a first target transmit power according to the first transmit power, the power backoff value, and the transmit power limit value.
关于步骤101至步骤105的实现细节，详见图6所述实施例中的描述说明，此处不再赘述。For implementation details of step 101 to step 105, please refer to the description in the embodiment shown in FIG6 and will not be repeated here.
201，第一信道是否为PRACH，并且PRACH的RRC状态为业务态。201, whether the first channel is PRACH, and the RRC state of PRACH is service state.
所谓PRACH(Physical Random Access Channel，物理随机接入信道)，是电子设备一开始发起呼叫时的接入信道，电子设备接收到快速物理接入信道(Fast Physical Access Channel，FPACH)响应消息后，会根据基站指示的信息在PRACH信道发送无线资源控制连接请求(Radio Resource Control Connection Request，RRC Connection Request)消息，进行完成RRC连接的建立操作。The so-called PRACH (Physical Random Access Channel) is the access channel when an electronic device initiates a call. The electronic device receives the Fast Physical Access Channel (Fast Physical Access Channel). After receiving the FPACH response message, a Radio Resource Control Connection Request (RRC Connection Request) message will be sent on the PRACH channel according to the information indicated by the base station to complete the RRC connection establishment operation.
此外，需要说明的是，在NR通讯系统中，RRC有3种状态，分别为IDLE(空闲态)、INACTIVE(不活跃态)、ACTIVE/CONNECTED(业务态)。In addition, it should be noted that in the NR communication system, RRC has three states, namely IDLE (idle state), INACTIVE (inactive state), and ACTIVE/CONNECTED (service state).
其中，当PRACH处于IDLE时，电子设备与无线网之间的RRC链路被释放，因此以上述调整方式1调整获得的第一目标发射功率，在该通道中发射信号不会对业务造成影响。当PRACH处于INACTIVE时，电子设备与无线网之间的RRC链路被暂停/中止，因此以上述调整方式1调整获得的第一目标发射功率，在该通道中发射信号也不会对业务造成影响。但，当PRACH处于ACTIVE/CONNECTED时，电子设备与无线网之间的RRC链路可用，因此在这种情况下，当PRACH作为电子设备的驻网信道时，不能限制该信道的发射功率。Among them, when PRACH is in IDLE, the RRC link between the electronic device and the wireless network is released. Therefore, the first target transmission power obtained by adjusting the above adjustment method 1 and transmitting signals in this channel will not affect the business. When PRACH is in INACTIVE, the RRC link between the electronic device and the wireless network is suspended/terminated. Therefore, the first target transmission power obtained by adjusting the above adjustment method 1 and transmitting signals in this channel will not affect the business. However, when PRACH is in ACTIVE/CONNECTED, the RRC link between the electronic device and the wireless network is available. Therefore, in this case, when PRACH is used as the resident channel of the electronic device, the transmission power of the channel cannot be limited.
基于此，在第一信道是PRACH，并且PRACH的RRC状态为业务态时，将执行步骤206；反之，则可以执行步骤202，继续判断第一业务是否设定的重要业务，即不可以降低发射功率的业务。Based on this, when the first channel is PRACH and the RRC state of PRACH is the service state, step 206 will be executed; otherwise, step 202 can be executed to continue to determine whether the first service is an important service, that is, a service whose transmission power cannot be reduced.
202，第一业务对应的发射信号是否是SRS。202: Whether the transmission signal corresponding to the first service is an SRS.
所谓SRS，即信道探测参考信号(Sounding Reference Signal)，是电子设备发送给记载的上行参考信号，体现了信道质量的好坏。具体地，天线轮发的SRS的会影响上线资源的调制与编码策略(Modulation and Coding Scheme，MCS)和多进多出(multiple in multiple out，mimo)权值，以及下行资源的MCS和mimo权值。而传输速率是基于MCS的索引值实现的。因此，MCS将所关注的影响通讯速率的因素作为表的列，将MCS索引作为行，形成一张速率表。所以，每一个MCS索引其实对应了一组参数下的物理传输速率。The so-called SRS, or Sounding Reference Signal, is an uplink reference signal sent by an electronic device to record, which reflects the quality of the channel. Specifically, the SRS sent by the antenna in turn will affect the modulation and coding scheme (MCS) and multiple in multiple out (MIMO) weights of the uplink resources, as well as the MCS and MIMO weights of the downlink resources. The transmission rate is achieved based on the index value of the MCS. Therefore, MCS uses the factors that affect the communication rate as the columns of the table and the MCS index as the rows to form a rate table. Therefore, each MCS index actually corresponds to a physical transmission rate under a set of parameters.
此外，还需要说明的是，载波切换(CS)和天线切换(AS)过程中涉及的SRS很可能会复用，因此如果对SRS的最大发射功率也进行限制，则同时会影响下行速率。即，限制SRS的输出功率(发射功率)，会导致信道的互易性被破坏，也就是输出功率的大小与对应的接收能力不匹配。并且，限制SRS的输出功率使得基站接收到SRS的信道的信噪比降低，会影响下行波束赋形的性能，对于用户来说，下载的速度会受到影响。In addition, it should be noted that the SRS involved in the carrier switching (CS) and antenna switching (AS) processes are likely to be reused, so if the maximum transmission power of the SRS is also limited, the downlink rate will also be affected. That is, limiting the output power (transmission power) of the SRS will cause the reciprocity of the channel to be destroyed, that is, the output power does not match the corresponding receiving capacity. In addition, limiting the output power of the SRS reduces the signal-to-noise ratio of the channel where the base station receives the SRS, which will affect the performance of the downlink beamforming. For users, the download speed will be affected.
故而，对于第一业务对应的发射信号是SRS，或者说第一信道中存在SRS时，将不限制第一信道的发射功率，直接以第一信道在当前周期支持的最大发射功率，即第一发射功率发射信号即可，即执行步骤206的操作。反之，则可以执行步骤203，继续判断当前信道中是否有其他设定的不可限制发射功率的信号。Therefore, when the transmission signal corresponding to the first service is SRS, or when SRS exists in the first channel, the transmission power of the first channel will not be limited, and the signal can be directly transmitted with the maximum transmission power supported by the first channel in the current period, that is, the first transmission power, that is, the operation of step 206 is performed. Otherwise, step 203 can be performed to continue to determine whether there are other signals with set transmission power that cannot be limited in the current channel.
203，第一信道是否是PUCCH，并且PUCCH中有SR信号。203: Whether the first channel is PUCCH and there is an SR signal in the PUCCH.
具体地，若第一信道是PUCCH，并且PUCCH中有SR信号，则执行步骤206；否则执行步骤204。Specifically, if the first channel is PUCCH and there is an SR signal in the PUCCH, step 206 is executed; otherwise, step 204 is executed.
204，PUCCH中是否有HARQ信号。204, whether there is a HARQ signal in the PUCCH.
具体地，若第一信道是PUCCH，并且PUCCH中有SR信号，则执行步骤206；否则执行步骤205。Specifically, if the first channel is PUCCH and there is an SR signal in the PUCCH, execute step 206; otherwise, execute step 205.
205，PUCCH中是否有第二信道状态信息。205. Whether there is second channel state information in the PUCCH.
具体地，若第一信道是PUCCH，并且PUCCH中有SR信号，则执行步骤206；否则执行步骤106。Specifically, if the first channel is PUCCH and there is an SR signal in the PUCCH, execute step 206; otherwise, execute step 106.
具体地，若第一信道是PUCCH，并且PUCCH中有SR信号，则执行步骤206；否则执行步骤204。Specifically, if the first channel is PUCCH and there is an SR signal in the PUCCH, step 206 is executed; otherwise, step 204 is executed.
需要说明的是，对于PUCCH(Physical Uplink Control Channel，物理上行链路控制信道)中传输的下行数据，当其传输的是调度请求(Scheduling Request，SR)信号、混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)信号、用于衡量第一信道传输下行数据时第一信道情况的第二信道状态信息、ACK信号、NACK信号时，如果限制PUCCH的发射公开，会影响上下行资源调度和下行数据的重传。It should be noted that for downlink data transmitted in PUCCH (Physical Uplink Control Channel), when it transmits Scheduling Request (SR) signal, Hybrid Automatic Repeat reQuest (HARQ) signal, second channel status information used to measure the first channel condition when the first channel transmits downlink data, ACK signal, NACK signal, if the public transmission of PUCCH is restricted, it will affect the uplink and downlink resource scheduling and the retransmission of downlink data.
其中，ACK(Acknowledgement)信号，是一种正向反馈，接收方收到数据后回复消息告知发送方时作出的响应信号。具体到本实施例中，例如为基站向电子设备作出的响应信号。The ACK (Acknowledgement) signal is a positive feedback, which is a response signal made by the receiver when it replies to the sender after receiving the data. Specifically in this embodiment, for example, it is a response signal made by the base station to the electronic device.
其中，NACK(Negative Acknowledgement)，是一种负向反馈，接收方只有在没有收到数据的时候才通知发送方。具体到本实施例中，例如为基站在没有接收到电子设备发送的数据时，向电子设备作出的响应信号。Among them, NACK (Negative Acknowledgement) is a negative feedback, and the receiver notifies the sender only when it has not received the data. Specifically in this embodiment, for example, it is a response signal made by the base station to the electronic device when it has not received the data sent by the electronic device.
其中，用于衡量第一信道传输下行数据时第一信道情况的第二信道状态信息CSI中可以包括信道质量指标(Channel Quality Indicator，CQI)、秩指示(rank indication，RI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)、RS资源指示符(CRI)等信息。Among them, the second channel state information CSI used to measure the condition of the first channel when the first channel transmits downlink data may include channel quality indicator (Channel Quality Indicator, CQI), rank indication (rank indication, RI), precoding matrix indication (Precoding Matrix Indicator, PMI), RS resource indicator (CRI) and other information.
应当理解地是，上述说明仅是为了更好地理解本实施例的技术方案而列举的示例，不作为对本实施例的唯一限制。It should be understood that the above description is merely an example listed for a better understanding of the technical solution of this embodiment, and is not intended to be the sole limitation to this embodiment.
故而，对于含有上述任一信号的场景，将不限制第一信道的发射功率，直接以第一信道在当前周期支持的最大发射功率，即第一发射功率发射信号即可，即执行步骤206的操作。Therefore, for a scenario containing any of the above signals, the transmit power of the first channel will not be limited, and the signal can be directly transmitted with the maximum transmit power supported by the first channel in the current period, that is, the first transmit power, that is, the operation of step 206 is performed.
否则，在确定第一信道不包括上述任一种信号时，可执行步骤106。Otherwise, when it is determined that the first channel does not include any of the above signals, step 106 may be executed.
106，在当前周期内，以第一目标发射功率，在第一信道中发射信号。106. In a current cycle, transmit a signal in a first channel at a first target transmit power.
关于步骤106的实现细节，详见图6所述实施例中的描述说明，此处不再赘述。For implementation details of step 106, please refer to the description in the embodiment shown in FIG. 6 and will not be repeated here.
206，在当前周期内，以第一发射功率，在第一信道中发射信号。206. In the current cycle, transmit a signal in the first channel with the first transmission power.
107，在第二业务的作业过程中，采用限制发射功率峰值或限制平均时间内的发射功率的方式，调整第二业务对应的第二信道的第二发射功率。107. During the operation of the second service, the second transmission power of the second channel corresponding to the second service is adjusted by limiting the transmission power peak value or limiting the transmission power within an average time.
108，根据调整后的第二发射功率，在第二通道发射信号。108. Transmit a signal on the second channel according to the adjusted second transmission power.
关于步骤107和步骤108的实现细节，详见图6所述实施例中的描述说明，此处不再赘述。For implementation details of step 107 and step 108, please refer to the description in the embodiment shown in FIG. 6 , which will not be repeated here.
由此，在以第一目标发射功率发射信号前，通过进一步判断第一通道是否为处于特定状态，或者含有特定信号的重要信道，如PRACH，PUCCH等，进而在确定第一信道不是特定的重要信道时，才在当前周期内，以第一目标发射功率，在第一信道中发射信号，从而可以避免这些重要信道的发射功率被调整，进而保证了重要信道的业务能够正常进行。在第一信道为特定的重要信道时，直接以第一信道当前支持的第一发射功率发射信息，从而保证了该信道对应的业务的正常进行。Therefore, before transmitting a signal at the first target transmission power, by further judging whether the first channel is in a specific state or an important channel containing a specific signal, such as PRACH, PUCCH, etc., and then determining that the first channel is not a specific important channel, the signal is transmitted in the first channel at the first target transmission power in the current cycle, thereby avoiding the transmission power of these important channels from being adjusted, thereby ensuring that the services of the important channels can proceed normally. When the first channel is a specific important channel, information is directly transmitted at the first transmission power currently supported by the first channel, thereby ensuring that the services corresponding to the channel proceed normally.
参见图9，示例性示出一种由AP侧和Modem侧配合实现的发射功率的调整进行方法，具体包括步骤301至步骤311。其中，步骤301至步骤304由AP侧的发射功率调整模块实现，步骤305至步骤311在Modem中实现。9 , a method for adjusting transmit power implemented by cooperation between the AP side and the Modem side is exemplarily shown, specifically including steps 301 to 311. Among them, steps 301 to 304 are implemented by the transmit power adjustment module on the AP side, and steps 305 to 311 are implemented in the Modem.
具体到本实施例中，在对发射功率进行调整时，不考虑当前业务具体为哪一类型的业务，统一按照上述所说的调整方式1进行处理。故而，未在本实施例中示出的具体实现细节，可以参见上述实施例，此处不再赘述。具体地，本实施例中的步骤301至步骤304的具体实现细节，可以参见上述实施例中的步骤102至步骤105；步骤305至步骤309的具体实现细节，可以参见上述实施例中的步骤201至步骤205；步骤310的具体实现细节，可以参见上述实施例中的步骤106；步骤311的具体实现细节，可以参见上述实施例中的步骤206。Specifically in this embodiment, when adjusting the transmission power, regardless of the specific type of the current service, it is uniformly processed according to the adjustment method 1 mentioned above. Therefore, for the specific implementation details not shown in this embodiment, refer to the above embodiment, and will not be repeated here. Specifically, the specific implementation details of steps 301 to 304 in this embodiment can refer to steps 102 to 105 in the above embodiment; the specific implementation details of steps 305 to 309 can refer to steps 201 to 205 in the above embodiment; the specific implementation details of step 310 can refer to step 106 in the above embodiment; the specific implementation details of step 311 can refer to step 206 in the above embodiment.
301，在电子设备执行业务的过程中，按照设定周期获取电子设备当前执行的业务对应的信道的传输上行数据的信道状态信息。301 , when an electronic device is executing a service, channel state information of uplink data transmission of a channel corresponding to a service currently executed by the electronic device is obtained according to a set period.
302，根据信道状态信息，确定信道在当前周期支持的发射功率。302. Determine the transmit power supported by the channel in the current period according to the channel state information.
303，根据信道状态信息，确定信道在当前周期的功率回退值。303: Determine a power backoff value of the channel in the current period according to the channel state information.
304，根据发射功率、功率回退值和发射功率限制值，调整发射功率。304. Adjust the transmit power according to the transmit power, the power backoff value, and the transmit power limit value.
305，信道是否为PRACH，并且PRACH的RRC状态为业务态。305: Whether the channel is PRACH, and the RRC state of PRACH is service state.
306，业务对应的发射信号是否是SRS。306: Whether the transmission signal corresponding to the service is SRS.
307，信道是否是PUCCH，并且PUCCH中有SR信号。307, whether the channel is PUCCH and there is an SR signal in the PUCCH.
308，PUCCH中是否有HARQ信号。308, whether there is a HARQ signal in the PUCCH.
309，PUCCH中是否有用于衡量传输下行数据的信道状态信息。309, whether there is channel state information in the PUCCH for measuring the transmission of downlink data.
310，在当前周期内，以步骤304中调整后的发射功率，在信道中发射信号。310 , in the current cycle, transmit a signal in the channel with the transmit power adjusted in step 304 .
311，在当前周期内，以步骤302中确定的发射功率，在信道中发射信号。311 , in the current cycle, transmit a signal in the channel with the transmit power determined in step 302 .
由此，不考虑电子设备当前执行的业务具体为哪一类型的业务，在当前业务的整个作业过程中，均周期性地评估该业务对应的信道在当前周期内的发射功率和该周期内信道对应的功率回退值，进而根据发射功率、功率回退值，以及电子设备当前所在区域对应的发射功率限制值，动态调整发射功率，实现了对电子设备可执行的所有业务的动态调整。Therefore, regardless of the specific type of service currently executed by the electronic device, during the entire operation process of the current service, the transmission power of the channel corresponding to the service in the current period and the power backoff value corresponding to the channel in the period are periodically evaluated, and then the transmission power is dynamically adjusted according to the transmission power, the power backoff value, and the transmission power limit value corresponding to the current area of the electronic device, thereby realizing dynamic adjustment of all services that can be executed by the electronic device.
此外，在根据调整后的发射功率在信道中发射信号前，通过进一步判断信道是否为处于业务态的PRACH，以及是否为没有传输SR信号、HARQ信号、用于衡量传输下行数据的信道状态信息的信道，在确定满足上述判断时，才根据调整后的发射功率在信道中发射信号，否则直接以当前信道支持的发射功率，在该信道中发射信号，即不调整发射功率。由此做到了既保证用户处于安全的电磁辐射范围，又能够兼顾最重要信道的发射功率需求，保证了重要信道的通信质量。In addition, before transmitting signals in the channel according to the adjusted transmit power, it is further determined whether the channel is a PRACH in service state, and whether it is a channel that does not transmit SR signals, HARQ signals, and channel state information used to measure downlink data transmission. Only when it is determined that the above judgments are met, the signal is transmitted in the channel according to the adjusted transmit power, otherwise the signal is directly transmitted in the channel with the transmit power supported by the current channel, that is, the transmit power is not adjusted. In this way, it is ensured that users are in a safe electromagnetic radiation range, and the transmit power requirements of the most important channels are taken into account, ensuring the communication quality of important channels.
