具体实施方式Detailed ways
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.
随着无线通信技术的快速发展，频谱资源变得愈加紧张，较高的频段很难实现较佳的覆盖。为了实现移动通信网络的更好覆盖，出现了中继(Relay)技术。3GPP(3rdGeneration Partnership Project，第三代合作伙伴计划)定义了多种中继策略，包括同频或异频无线中继，等等。中继设备(如直放站)由于在成本、成熟度等方面具有优势，是当前移动通信网络最常用的中继手段。With the rapid development of wireless communication technology, spectrum resources have become increasingly tight, and it is difficult to achieve better coverage in higher frequency bands. In order to achieve better coverage of mobile communication networks, relay technology has emerged. 3GPP (3rdGeneration Partnership Project) defines a variety of relay strategies, including same-frequency or inter-frequency wireless relay, and so on. Relay equipment (such as repeaters) is the most commonly used relay method in current mobile communication networks due to its advantages in cost and maturity.
在最新的5G(5th Generation Mobile Communication Technology，第五代移动通信技术)标准中，无线中继也是非常重要的覆盖手段，特别在毫米波频段的应用中，由于电磁波信号空间损耗大、传播路径短且穿透能力差，使得中继技术成为改善5G覆盖的关键技术。In the latest 5G (5th Generation Mobile Communication Technology, fifth generation mobile communication technology) standard, wireless relay is also a very important coverage method. Especially in the application of millimeter wave frequency band, due to the large space loss of electromagnetic wave signal and short propagation path, And the penetration ability is poor, making relay technology a key technology to improve 5G coverage.
以中继技术应用在5G中为例，Massive MIMO(大规模天线技术，亦称为LargeScale MIMO)是5G中提高系统容量和频谱利用率的关键技术，实际商用网性能表明，即使使用有限的64T64R天线数的Massive MIMO，也可大幅提升近十倍的单用户链路性能和4到8倍的系统容量。为了充分发挥Massive MIMO的性能，5G中引入了用户级的波束管理技术，使得广播信道及业务信道能获取到更高的波束赋型增益，提升性能。这样，基站基于大规模天线技术，通过不同赋型的波束向中继设备发送广播信号和业务信号，由中继设备将广播信号和业务信号转发至终端。Taking the application of relay technology in 5G as an example, Massive MIMO (large-scale antenna technology, also known as LargeScale MIMO) is a key technology in 5G to improve system capacity and spectrum utilization. Actual commercial network performance shows that even with limited 64T64R Massive MIMO with a higher number of antennas can also significantly improve single-user link performance by nearly ten times and system capacity by 4 to 8 times. In order to give full play to the performance of Massive MIMO, user-level beam management technology is introduced in 5G, allowing broadcast channels and service channels to obtain higher beam forming gains and improve performance. In this way, based on large-scale antenna technology, the base station sends broadcast signals and service signals to the relay device through different shaped beams, and the relay device forwards the broadcast signals and service signals to the terminal.
示例性地，参见图1，图1为一种示例性地基站通过波束向中继设备发送信号的示意图。如图1所示，基站采用较“胖”波束(图1所示的广播信号波束1和广播信号波束2)向中继设备发送广播信号，采用较“窄”波束(图1所示的业务信号波束1、业务信号波束2和业务信号波束3)向中继设备发送业务信号，广播信号波束和业务信号波束具有不同的波束赋型。Exemplarily, see FIG. 1 , which is a schematic diagram of an exemplary base station transmitting signals to a relay device through a beam. As shown in Figure 1, the base station uses fatter beams (broadcast signal beam 1 and broadcast signal beam 2 shown in Figure 1) to send broadcast signals to the relay equipment, and uses narrower beams (the service shown in Figure 1 Signal beam 1, service signal beam 2 and service signal beam 3) send service signals to the relay device, and the broadcast signal beam and the service signal beam have different beam shapes.
但是，上述基于中继设备的通信方式，随着业务信号功率的增加，广播信号的功率会降低，由于广播信号的功率大小对中继设备的覆盖范围起着决定性作用，这就导致中继设备的网络覆盖随业务信号功率的变化而变化，出现中继设备的网络覆盖效果较差的现象。However, in the above communication method based on relay equipment, as the power of the service signal increases, the power of the broadcast signal will decrease. Since the power of the broadcast signal plays a decisive role in the coverage of the relay equipment, this results in the relay equipment The network coverage changes with the change of service signal power, and the network coverage effect of relay equipment is poor.
鉴于此，本申请实施例通过接收下行通信信号，并根据下行通信信号，获取下行通信信号中的广播信号对应的信号参数信息和信号功率数据，而后，根据信号参数信息生成广播信号对应的初始补偿信号，并利用信号功率数据对初始补偿信号进行信号幅度补偿，得到目标补偿信号，再对下行通信信号和目标补偿信号进行叠加处理，以对广播信号进行补偿，这样，由于广播信号的功率大小对中继设备的覆盖范围起着决定性作用，本申请实施例通过对广播信号进行补偿，增强了下行通信信号中广播信号的信号功率，从而提升了中继设备的网络覆盖效果。In view of this, the embodiment of the present application receives the downlink communication signal and obtains the signal parameter information and signal power data corresponding to the broadcast signal in the downlink communication signal according to the downlink communication signal, and then generates the initial compensation corresponding to the broadcast signal according to the signal parameter information. signal, and use the signal power data to perform signal amplitude compensation on the initial compensation signal to obtain the target compensation signal, and then superimpose the downlink communication signal and the target compensation signal to compensate for the broadcast signal. In this way, due to the power of the broadcast signal, The coverage of the relay device plays a decisive role. The embodiment of the present application enhances the signal power of the broadcast signal in the downlink communication signal by compensating the broadcast signal, thereby improving the network coverage effect of the relay device.

在一种可能的实施方式中，信号参数信息包括定时同步信息和频偏信息，定时同步信息可以是上述的PCI、SFN、SSB SCS、MIB码流信息、SSB Index、10ms定时位置等信息，中继设备可以根据定时同步信息生成广播信号对应的原始补偿信号，并利用频偏信息对原始补偿信号进行频率补偿，得到初始补偿信号，以此实现根据信号参数信息生成广播信号对应的初始补偿信号的过程。In a possible implementation, the signal parameter information includes timing synchronization information and frequency offset information. The timing synchronization information can be the above-mentioned PCI, SFN, SSB SCS, MIB code stream information, SSB Index, 10ms timing position and other information, in The relay device can generate the original compensation signal corresponding to the broadcast signal based on the timing synchronization information, and use the frequency offset information to perform frequency compensation on the original compensation signal to obtain the initial compensation signal, thereby realizing the generation of the initial compensation signal corresponding to the broadcast signal based on the signal parameter information. process.
假设，频偏信息表征基站的广播信号的频偏为f，中继设备则对原始补偿信号也补偿f频偏，以此保障初始补偿信号的频偏和广播信号的频偏一致，提升信号补偿的准确性。Assume that the frequency offset information represents the frequency offset of the broadcast signal of the base station as f, and the relay equipment also compensates the frequency offset of f for the original compensation signal to ensure that the frequency offset of the initial compensation signal is consistent with the frequency offset of the broadcast signal and improve signal compensation. accuracy.
接着，中继设备利用信号功率数据对初始补偿信号进行信号幅度补偿。以下，通过两种不同的实施方式，对中继设备利用信号功率数据对初始补偿信号进行信号幅度补偿的过程进行简单介绍。Then, the relay device uses the signal power data to perform signal amplitude compensation on the initial compensation signal. The following is a brief introduction to the process of signal amplitude compensation of the initial compensation signal by the relay device using the signal power data through two different implementation methods.
在一种可能的实施方式中，以信号功率数据包括广播信号对应的目标功率补偿值为例，中继设备可以将目标功率补偿值进行功率域转换，将目标功率补偿值转换至对数域，得到幅度补偿值，终端利用该幅度补偿值对初始补偿信号进行信号幅度补偿，得到目标补偿信号。In a possible implementation, taking the signal power data including the target power compensation value corresponding to the broadcast signal as an example, the relay device can perform power domain conversion on the target power compensation value, and convert the target power compensation value into the logarithmic domain, The amplitude compensation value is obtained, and the terminal uses the amplitude compensation value to perform signal amplitude compensation on the initial compensation signal to obtain the target compensation signal.
在另一种可能的实施方式中，信号功率数据可以包括上述广播信号对应的第一功率值以及广播信号对应的目标功率补偿值，参见图4，中继设备可以执行图4所示的步骤401和步骤402实现利用信号功率数据对初始补偿信号进行信号幅度补偿，得到目标补偿信号的过程：In another possible implementation, the signal power data may include the first power value corresponding to the broadcast signal and the target power compensation value corresponding to the broadcast signal. Referring to Figure 4, the relay device may perform step 401 shown in Figure 4. and step 402 to realize the process of using signal power data to perform signal amplitude compensation on the initial compensation signal to obtain the target compensation signal:
步骤401，中继设备根据第一功率值和目标功率补偿值获取幅度补偿值。Step 401: The relay device obtains the amplitude compensation value according to the first power value and the target power compensation value.
本申请实施例中，中继设备可以对第一功率值和目标功率补偿值进行功率域转换处理，得到幅度补偿值。In this embodiment of the present application, the relay device may perform power domain conversion processing on the first power value and the target power compensation value to obtain the amplitude compensation value.
示例性地，中继设备可以通过如下公式，对第一功率值SS-RSRP和目标功率补偿值P进行功率域转换处理，得到幅度补偿值A：For example, the relay device can perform power domain conversion processing on the first power value SS-RSRP and the target power compensation value P through the following formula to obtain the amplitude compensation value A:
在一种可能的实施方式中，中继设备根据第一功率值和目标功率补偿值获取幅度补偿值之前，中继设备还可以检测该目标功率补偿值是否超过预设的最大功率补偿值，这样，若目标功率补偿值未超过最大功率补偿值，中继设备则根据第一功率值和目标功率补偿值获取幅度补偿值。In a possible implementation, before the relay device obtains the amplitude compensation value based on the first power value and the target power compensation value, the relay device can also detect whether the target power compensation value exceeds the preset maximum power compensation value, so that , if the target power compensation value does not exceed the maximum power compensation value, the relay device obtains the amplitude compensation value based on the first power value and the target power compensation value.
而若目标功率补偿值超过最大功率补偿值，中继设备则可以根据第一功率值和最大功率补偿值获取幅度补偿值，这样可以实现补偿保护，避免幅度补偿值无限增大造成的补偿误差。If the target power compensation value exceeds the maximum power compensation value, the relay device can obtain the amplitude compensation value based on the first power value and the maximum power compensation value. This can achieve compensation protection and avoid compensation errors caused by infinite increases in the amplitude compensation value.
步骤402，中继设备利用幅度补偿值对初始补偿信号进行信号幅度补偿，得到目标补偿信号。Step 402: The relay device uses the amplitude compensation value to perform signal amplitude compensation on the initial compensation signal to obtain a target compensation signal.
如上文所述，初始补偿信号可以是归一化地、幅度为1的广播信号，这样，中继设备利用该幅度补偿值对初始补偿信号的幅度进行相应倍数的放大，得到目标补偿信号。As mentioned above, the initial compensation signal can be a normalized broadcast signal with an amplitude of 1. In this way, the relay device uses the amplitude compensation value to amplify the amplitude of the initial compensation signal by a corresponding multiple to obtain the target compensation signal.
可以理解的是，该目标补偿信号的幅度为该幅度补偿值表征的幅度大小。It can be understood that the amplitude of the target compensation signal is the amplitude represented by the amplitude compensation value.
步骤303，中继设备对下行通信信号和目标补偿信号进行叠加处理，以对广播信号进行补偿。Step 303: The relay device performs superposition processing on the downlink communication signal and the target compensation signal to compensate the broadcast signal.
中继设备获取到目标补偿信号之后，中继设备可以将目标补偿信号与下行通信信号在数字域实现时域对齐相加，从而对下行通信信号和目标补偿信号实现叠加处理，叠加处理后会增强下行通信信号中的广播信号，即实现对广播信号的补偿。After the relay device obtains the target compensation signal, the relay device can time-align and add the target compensation signal and the downlink communication signal in the digital domain, thereby superimposing the downlink communication signal and the target compensation signal. After the superposition processing, the signal will be enhanced. The broadcast signal in the downlink communication signal realizes the compensation of the broadcast signal.
中继设备对下行通信信号和目标补偿信号进行叠加处理之后，再向终端输出叠加处理后得到的信号。After the relay device superimposes the downlink communication signal and the target compensation signal, it outputs the superimposed signal to the terminal.
作为一种实施方式，中继设备还可以进行系统内10ms定时维护及SFN更新：中继设备周期性地通过执行PSS/SSS搜索以及MIB解码及码流解析过程，跟踪广播信号的定时偏差值，然后进行时频偏调整。As an implementation method, the relay device can also perform 10ms scheduled maintenance and SFN updates within the system: the relay device periodically tracks the timing deviation value of the broadcast signal by performing PSS/SSS search, MIB decoding and code stream analysis processes. Then perform time-frequency offset adjustment.
其中，该定时偏差值等于基站的10ms定时位置(该10ms定时位置与上文所述的信号参数信息所包括的10ms定时位置含义一致，均指基站的起始发送位置)与中继设备的10ms定时位置的差值。Among them, the timing deviation value is equal to the 10ms timing position of the base station (the 10ms timing position has the same meaning as the 10ms timing position included in the signal parameter information mentioned above, both refer to the starting transmitting position of the base station) and the 10ms timing position of the relay device. The difference in timing positions.
其中，时偏调整可以快速调整10ms定时位置，实现中继设备与基站时间对齐。频偏调整方法包括：1)采用电压控制的振荡器方式调整晶振频率，实现中继设备与基站频率对齐；2)采用数字频率调整机制实现频偏对齐，其中，数字频率调整机制可以采用百ms级别计数器，通过调整计数器上限值，实现频率调整。Among them, time offset adjustment can quickly adjust the 10ms timing position to achieve time alignment between the relay equipment and the base station. Frequency offset adjustment methods include: 1) using a voltage-controlled oscillator to adjust the crystal oscillator frequency to achieve frequency alignment between relay equipment and base stations; 2) using a digital frequency adjustment mechanism to achieve frequency offset alignment, where the digital frequency adjustment mechanism can take hundreds of milliseconds Level counter realizes frequency adjustment by adjusting the upper limit of the counter.
时频偏调整之后，中继设备可以对时频偏调整之后的信号进行PDCCH(PhysicalDownlink Control Channel，物理下行控制信道)搜索及PDSCH(Physical DownlinkShared CHannel，物理下行共享信道)搜索，以搜索Sib1及Si信号，并对搜索的索Sib1及Si信号解析，得到时隙配比信息、基站运营商PLMN信息。After the time-frequency offset is adjusted, the relay device can perform a PDCCH (Physical Downlink Control Channel, physical downlink control channel) search and a PDSCH (Physical Downlink Shared CHannel, physical downlink shared channel) search on the adjusted signal to search for Sib1 and Si signals, and analyze the searched index Sib1 and Si signals to obtain time slot ratio information and base station operator PLMN information.
这样，中继设备可以基于时隙配比信息确定中继设备的发送时隙，从而在确定的发送时隙向终端输出叠加处理后得到的信号。In this way, the relay device can determine the transmission time slot of the relay device based on the time slot ratio information, so as to output the signal obtained after superposition processing to the terminal in the determined transmission time slot.
上述实施例通过接收下行通信信号，并根据下行通信信号，获取下行通信信号中的广播信号对应的信号参数信息和信号功率数据，而后，根据信号参数信息生成广播信号对应的初始补偿信号，并利用信号功率数据对初始补偿信号进行信号幅度补偿，得到目标补偿信号，再对下行通信信号和目标补偿信号进行叠加处理，以对广播信号进行补偿，这样，由于广播信号的功率大小对中继设备的覆盖范围起着决定性作用，本申请实施例通过对广播信号进行补偿，增强了下行通信信号中广播信号的信号功率，从而提升了中继设备的网络覆盖效果。The above embodiment receives the downlink communication signal and obtains the signal parameter information and signal power data corresponding to the broadcast signal in the downlink communication signal according to the downlink communication signal, and then generates the initial compensation signal corresponding to the broadcast signal according to the signal parameter information, and uses The signal power data performs signal amplitude compensation on the initial compensation signal to obtain the target compensation signal, and then superimposes the downlink communication signal and the target compensation signal to compensate for the broadcast signal. In this way, the power of the broadcast signal affects the relay equipment. Coverage plays a decisive role. The embodiment of the present application enhances the signal power of the broadcast signal in the downlink communication signal by compensating the broadcast signal, thereby improving the network coverage effect of the relay device.

在一个实施例中，基于图4所示的实施例，参见图5，本实施例涉及的是中继设备如何根据下行通信信号获取目标功率补偿值的过程。如图5所示，该过程包括步骤501和步骤502：In one embodiment, based on the embodiment shown in Figure 4, referring to Figure 5, this embodiment relates to the process of how a relay device obtains a target power compensation value based on a downlink communication signal. As shown in Figure 5, the process includes steps 501 and 502:
步骤501，中继设备根据下行通信信号，获取下行通信信号中的业务信号的第二功率值。Step 501: The relay device obtains the second power value of the service signal in the downlink communication signal according to the downlink communication signal.

以下，通过几种不同的实施方式，对中继设备根据下行通信信号获取下行通信信号中的业务信号的第二功率值的过程进行简单介绍。Below, through several different implementations, the process of the relay device obtaining the second power value of the service signal in the downlink communication signal according to the downlink communication signal is briefly introduced.
在步骤501一种可能的实施方式中，参见图6，步骤501可以包括图6所示的步骤601、步骤602和步骤603：In a possible implementation of step 501, referring to Figure 6, step 501 may include step 601, step 602 and step 603 shown in Figure 6:
步骤601，中继设备获取下行通信信号中各RE信号的信号功率值。Step 601: The relay device obtains the signal power value of each RE signal in the downlink communication signal.
频率上一个子载波及时域上一个符号称为一个RE(Resource Element，最小资源单位)，RE信号的数量与下行通信信号对应的业务带宽正相关，例如，业务带宽为100M，RE信号的数量则可能最大有3000个。One subcarrier on the frequency and one symbol in the time domain is called an RE (Resource Element, the minimum resource unit). The number of RE signals is positively related to the service bandwidth corresponding to the downlink communication signal. For example, if the service bandwidth is 100M, the number of RE signals is There may be up to 3,000.
中继设备通过功率测量，得到下行通信信号中各RE信号的信号功率值。The relay device obtains the signal power value of each RE signal in the downlink communication signal through power measurement.
步骤602，对于每个RE信号，若RE信号的信号功率值与第一功率值的差值在预设的功率差值范围内，中继设备则确定RE信号为有效RE信号。Step 602: For each RE signal, if the difference between the signal power value of the RE signal and the first power value is within a preset power difference range, the relay device determines that the RE signal is a valid RE signal.
中继设备将每个RE信号的信号功率值和广播信号的第一功率值作差，并检测每个RE信号对应的差值是否在预设的功率差值范围内，该功率差值范围可以是在0附近波动的数值范围，该功率差值范围可以是人工根据经验设置的。The relay device makes a difference between the signal power value of each RE signal and the first power value of the broadcast signal, and detects whether the difference corresponding to each RE signal is within a preset power difference range. The power difference range can be It is a numerical range that fluctuates around 0. This power difference range can be set manually based on experience.
若某个RE信号的信号功率值与第一功率值的差值在该功率差值范围内，则表征该RE信号与广播信号的功率差异不是很大，从而确定该RE信号是有效RE信号。If the difference between the signal power value of a certain RE signal and the first power value is within the power difference range, it means that the power difference between the RE signal and the broadcast signal is not very large, thereby determining that the RE signal is a valid RE signal.
反之，若某个RE信号的信号功率值与第一功率值的差值不在该功率差值范围内，则表征该RE信号与广播信号的功率差异较大，从而确定该RE信号不是有效RE信号。On the contrary, if the difference between the signal power value of a certain RE signal and the first power value is not within the power difference range, it means that the power difference between the RE signal and the broadcast signal is large, thereby determining that the RE signal is not a valid RE signal. .
示例性地，参见图7，图7为一种示例性地下行通信信号中各RE信号的示意图。如图7所示，每个小方框即为一个RE信号；图7中第一区域(两个虚线框内的区域)中各RE信号的信号功率值与第一功率值的差值均在预设的功率差值范围内，即第一区域中各RE信号均为有效RE信号；图7中第二区域(除两个虚线框内区域的其他区域)中的各RE信号的信号功率值与第一功率值的差值均不在该功率差值范围内，即第二区域中各RE信号均不是有效RE信号。Exemplarily, see FIG. 7 , which is a schematic diagram of each RE signal in an exemplary downlink communication signal.

The second power value is obtained by averaging the signal power values of the RE signals. That is, the relay device selects multiple target RE signals with the largest signal power values from each valid RE signal as the basis for statistical averaging, thereby implementing step 603. process.
在步骤501另一种可能的实施方式中，参见图8，步骤501可以包括图8所示的步骤801和步骤802：In another possible implementation of step 501, referring to Figure 8, step 501 may include step 801 and step 802 shown in Figure 8:

中继设备根据下行通信信号获取下行通信信号中的业务信号的第二功率值之后，中继设备继续根据第一功率值和第二功率值之间的大小关系，确定该大小关系匹配的目标功率补偿值。After the relay device obtains the second power value of the service signal in the downlink communication signal according to the downlink communication signal, the relay device continues to determine the target power matching the size relationship based on the magnitude relationship between the first power value and the second power value. compensation value.
这样，上述实施例通过不同的实施方式自动对下行通信信号中的业务信号的功率进行有效准确测量，测量过程中继设备的计算量小，有利于节省中继设备的功耗。In this way, the above embodiments automatically and effectively measure the power of the service signal in the downlink communication signal through different implementation methods. The calculation amount of the relay device during the measurement process is small, which is beneficial to saving the power consumption of the relay device.
在一个实施例中，基于图5所示的实施例，参见图9，本实施例涉及的是中继设备如何根据大小关系确定该大小关系对应的目标功率补偿值的过程。如图9所示，该过程可以包括步骤901、步骤902和步骤903：In one embodiment, based on the embodiment shown in FIG. 5 , referring to FIG. 9 , this embodiment relates to the process of how the relay device determines the target power compensation value corresponding to the size relationship based on the size relationship. As shown in Figure 9, the process may include step 901, step 902 and step 903:
步骤901，中继设备获取广播信号对应的初始功率补偿值。Step 901: The relay device obtains the initial power compensation value corresponding to the broadcast signal.
可选地，该初始功率补偿值可以是初始化的功率补偿值，例如为0dB。Optionally, the initial power compensation value may be an initialized power compensation value, for example, 0 dB.
可选地，中继设备可以检测下行通信信号的接收功率是否超过预设的最大接收功率，若下行通信信号的接收功率超过最大接收功率，中继设备则确定初始功率补偿值为第一值，若下行通信信号的接收功率未超过最大接收功率，中继设备则确定初始功率补偿值为第二值，其中，第一值小于第二值。Optionally, the relay device can detect whether the received power of the downlink communication signal exceeds the preset maximum received power. If the received power of the downlink communication signal exceeds the maximum received power, the relay device determines the initial power compensation value to be the first value, If the received power of the downlink communication signal does not exceed the maximum received power, the relay device determines the initial power compensation value to be the second value, wherein the first value is smaller than the second value.
该最大接收功率可以是由中继设备的硬件条件决定的，或者也可以是基站配置的，若下行通信信号的接收功率超过最大接收功率，则第一值可以是最大接收功率减去下行通信信号的接收功率，若下行通信信号的接收功率未超过最大接收功率，则第二值可以是初始化的功率补偿值，例如为0dB。The maximum received power may be determined by the hardware conditions of the relay device, or may be configured by the base station. If the received power of the downlink communication signal exceeds the maximum received power, the first value may be the maximum received power minus the downlink communication signal. If the received power of the downlink communication signal does not exceed the maximum received power, the second value may be an initialized power compensation value, for example, 0 dB.
步骤902，若大小关系为第一功率值小于第二功率值，中继设备则获取第二功率值和第一功率值的功率值差值，并将初始功率补偿值和功率值差值的和值作为目标功率补偿值。Step 902: If the magnitude relationship is that the first power value is less than the second power value, the relay device obtains the power value difference between the second power value and the first power value, and calculates the sum of the initial power compensation value and the power value difference. value as the target power compensation value.
如上文所述，下行通信信号可以包括广播信号和业务信号，随着业务信号的功率的增加，会对广播信道的功率造成压制，即广播信号的功率会减小。本申请实施例中，若检测到广播信号的第一功率值小于业务信号的第二功率值，中继设备则利用第二功率值减去第一功率值得到功率值差值，并将初始功率补偿值和功率值差值的和值作为目标功率补偿值，这样，以增大广播信号的功率，避免对广播信道的功率造成压制所导致的覆盖效果差。As mentioned above, downlink communication signals may include broadcast signals and service signals. As the power of the service signal increases, the power of the broadcast channel will be suppressed, that is, the power of the broadcast signal will decrease. In the embodiment of the present application, if it is detected that the first power value of the broadcast signal is less than the second power value of the service signal, the relay device subtracts the first power value from the second power value to obtain the power value difference, and adds the initial power value to the first power value of the broadcast signal. The sum of the compensation value and the power value difference is used as the target power compensation value, so as to increase the power of the broadcast signal and avoid poor coverage effect caused by suppressing the power of the broadcast channel.
步骤903，若大小关系为第一功率值等于第二功率值，中继设备则将初始功率补偿值作为目标功率补偿值。Step 903: If the magnitude relationship is that the first power value is equal to the second power value, the relay device uses the initial power compensation value as the target power compensation value.
若广播信号的第一功率值等于业务信号的第二功率值，则不需要对广播信号补偿业务信号与广播信号之间的功率差值，从而直接将初始功率补偿值作为目标功率补偿值。如上文所述，初始功率补偿值可以是上述的第一值或第二值。If the first power value of the broadcast signal is equal to the second power value of the service signal, there is no need to compensate the broadcast signal for the power difference between the service signal and the broadcast signal, and the initial power compensation value is directly used as the target power compensation value. As mentioned above, the initial power compensation value may be the above-mentioned first value or second value.
这样，上述实施例通过根据广播信号的第一功率值和业务信号的第二功率值之间的大小关系，确定广播信号对应的目标功率补偿值，再根据目标功率补偿值或者根据广播信号的第一功率值和目标功率补偿值对初始补偿信号进行信号幅度补偿，得到目标补偿信号，以对广播信号进行补偿，提升广播信号的覆盖效果。In this way, the above embodiment determines the target power compensation value corresponding to the broadcast signal based on the relationship between the first power value of the broadcast signal and the second power value of the service signal, and then determines the target power compensation value corresponding to the broadcast signal based on the target power compensation value or based on the third power value of the broadcast signal. A power value and a target power compensation value are used to compensate the signal amplitude of the initial compensation signal to obtain a target compensation signal to compensate the broadcast signal and improve the coverage effect of the broadcast signal.
