本发明涉及通信技术领域，尤其涉及一种基于非授权频段的信号传输方法和通信设备。The present invention relates to the field of communication technologies, and in particular, to a signal transmission method and communication device based on an unlicensed frequency band.
背景技术Background technique
在5G(5th-generation，第五代移动通信技术)系统中，要采用非授权的频段进行数据的传输，则信号的发送端需要满足非授权频段的使用规则。对于非授权的频段，发送端在发送信号之前需要监听该频段是否被占用(或空闲)，如果没有被占用(或空闲)，则发送端可以进行信号的发送。上述资源空闲检测的过程即LBT(Listen-Before-Talk，先听后说)过程。In a 5G (5th-generation, fifth-generation mobile communication technology) system, to use an unlicensed frequency band for data transmission, the sender of the signal needs to meet the usage rules of the unlicensed frequency band. For an unlicensed frequency band, the sender needs to monitor whether the frequency band is occupied (or idle) before sending a signal. If it is not occupied (or idle), the sender can send the signal. The above-mentioned process of resource idle detection is an LBT (Listen-Before-Talk, listen first and then talk) process.
例如，非授权频段的随机接入过程中，UE(User Equipment，用户设备)在确定可用的随机接入资源时，需要对多个资源位置进行资源是否空闲的检测(即LBT)。这样，非授权频段的随机接入过程需要UE经过多次LBT过程。又例如，非授权频段的上行(或下行)调度请求过程中，同样需要通信设备(UE或网络侧设备)经过多次LBT过程。For example, in a random access process in an unlicensed frequency band, when a UE (User Equipment, user equipment) determines available random access resources, it needs to detect whether resources are free (ie, LBT) for multiple resource locations. In this way, the random access procedure of the unlicensed frequency band requires the UE to go through multiple LBT procedures. For another example, in the uplink (or downlink) scheduling request process of the unlicensed frequency band, the communication device (UE or network side device) also needs to go through multiple LBT processes.
可见，由于非授权频段的通信过程中需要通信设备进行多次LBT过程，从而导致通信设备在非授权频段的资源空闲检测上需要消耗较多的电能。It can be seen that, because the communication device in the unlicensed frequency band needs to perform multiple LBT processes, the communication device needs to consume a lot of power in the resource idle detection of the unlicensed frequency band.

As shown in FIG. 1 , it includes a
在对本发明实施例进行具体说明之前，先对NR-U(New RAT Un-licensed，新空口-非授权)进行如下简单介绍。Before the specific description of the embodiments of the present invention, a brief introduction to NR-U (New RAT Un-licensed, New RAT Un-licensed) is made as follows.
在5G系统中，要采用非授权的频段进行数据的收发，则信号的发送端需要满足非授权频段的使用规则。对于非授权的频段，发送端在发送信号之前需要监听该频段是否被占用(或空闲)，如果没有被占用(或空闲)，则发送端可以进行信号的发送。上述资源空闲检测的过程即LBT过程。In the 5G system, to use the unlicensed frequency band for data transmission and reception, the sender of the signal needs to meet the usage rules of the unlicensed frequency band. For an unlicensed frequency band, the sender needs to monitor whether the frequency band is occupied (or idle) before sending a signal. If it is not occupied (or idle), the sender can send the signal. The above process of resource idle detection is the LBT process.
由上述可知，通信设备在非授权频段的通信过程中，需要进行多次LBT过程，这将导致通信设备在非授权频段的资源空闲检测上需要消耗较多的电能。It can be seen from the above that the communication device needs to perform multiple LBT processes during the communication process in the unlicensed frequency band, which will cause the communication device to consume more power in the resource idle detection of the unlicensed frequency band.
为了解决上述问题，本发明实施例提供一种如图1所示的基于非授权频段的信号发送系统，并提供一种应用于该信号发送系统的基于非授权频段的信号传输方法，如下：In order to solve the above problem, an embodiment of the present invention provides a signal transmission system based on an unlicensed frequency band as shown in FIG. 1, and provides a signal transmission method based on an unlicensed frequency band applied to the signal transmission system, as follows:
在目标传输资源满足预设条件的情况下，直接使用所述目标传输资源传输当前信号；其中，所述预设条件成立至少包括：在传输所述当前信号之前的预设时间内，所述目标传输资源传输过在先信号。In the case that the target transmission resource satisfies the preset condition, the target transmission resource is directly used to transmit the current signal; wherein, the establishment of the preset condition at least includes: within a preset time before transmitting the current signal, the target The transmission resource transmits the previous signal.
上述目标传输资源为属于非授权频段的传输资源。The above-mentioned target transmission resources are transmission resources belonging to unlicensed frequency bands.
该目标传输资源为一个频域资源，该目标传输资源在不同的时域(或不同的时间节点)上可以传输不同的信号。也就是说，上述在先信号和当前信号在同一频域资源(即目标传输资源)的不同时域上进行传输。The target transmission resource is a frequency domain resource, and the target transmission resource can transmit different signals in different time domains (or different time nodes). That is to say, the preceding signal and the current signal are transmitted in different time domains of the same frequency domain resource (ie, the target transmission resource).
上述传输当前信号之前的预设时间可以理解为当前信号预定发送时间之前的一段较短的时间，例如，当前信号预定发送时间之前的16微秒。该预设时间可以通过所述网络侧设备配置，也可以通过协议约定。The above preset time before transmitting the current signal can be understood as a short period of time before the scheduled sending time of the current signal, for example, 16 microseconds before the scheduled sending time of the current signal. The preset time may be configured by the network-side device, or may be agreed upon in a protocol.
属于非授权频段的传输资源在传输当前信号之前的预设时间内，若传输过在先信号，则可以认为该传输资源满足上述预设条件。在传输资源满足预设条件的情况下，该传输资源可以理解为“不用做LBT的传输资源”，当前信号的传输则可以不用经过LBT过程，可以直接使用该传输资源传输当前信号。If the transmission resource belonging to the unlicensed frequency band has transmitted the previous signal within the preset time before the current signal is transmitted, it can be considered that the transmission resource satisfies the above-mentioned preset condition. When the transmission resource satisfies the preset condition, the transmission resource can be understood as "transmission resource that does not need to be used for LBT", and the transmission of the current signal does not need to go through the LBT process, and the transmission resource can be directly used to transmit the current signal.
可以理解地，由于上述传输资源在传输当前信号之前的较短时间内传输过在先信号，该传输资源在较短时间内还来不及再次被占用，或者说，该传输资源在较短时间内被占用的可能性很小。因此，该传输资源在传输当前信号时，可以认为是空闲的资源。从而，通信设备可以直接使用该传输资源进行信号传输，而不需要对该传输资源进行LBT。Understandably, because the above-mentioned transmission resource transmits the previous signal in a relatively short period of time before transmitting the current signal, the transmission resource cannot be occupied again in a relatively short period of time, or in other words, the transmission resource is occupied in a relatively short period of time. The possibility of occupancy is low. Therefore, the transmission resource can be regarded as an idle resource when the current signal is transmitted. Therefore, the communication device can directly use the transmission resource for signal transmission without performing LBT on the transmission resource.
本发明实施例中，在通信设备进行信号传输前的较短的时间内，如果某个属于非授权频段的传输资源传输过在先信号，则通信设备可以直接使用该传输资源进行信号传输，而不需要对该传输资源进行LBT。这样，可以减少通信设备在非授权频段的通信过程中进行LBT的次数，从而可以减少通信设备在非授权频段的资源空闲检测上消耗的电能。In the embodiment of the present invention, in a short period of time before the communication device performs signal transmission, if a certain transmission resource belonging to an unlicensed frequency band transmits a previous signal, the communication device can directly use the transmission resource for signal transmission, and No LBT is required for this transmission resource. In this way, the number of times that the communication device performs LBT in the communication process in the unlicensed frequency band can be reduced, thereby reducing the power consumption of the communication device in the detection of resource idleness in the unlicensed frequency band.
图2是本发明实施例提供的一种基于非授权频段的信号传输方法的流程图。如图2所示，基于非授权频段的信号传输方法，应用于UE或网络侧设备，该方法包括以下步骤：FIG. 2 is a flowchart of a signal transmission method based on an unlicensed frequency band provided by an embodiment of the present invention. As shown in FIG. 2 , a signal transmission method based on an unlicensed frequency band is applied to a UE or a network side device, and the method includes the following steps:
步骤201：在目标传输资源满足预设条件的情况下，直接使用所述目标传输资源传输当前信号；其中，所述预设条件成立至少包括：在传输所述当前信号之前的预设时间内，所述目标传输资源传输过在先信号。Step 201: In the case that the target transmission resource satisfies the preset condition, directly use the target transmission resource to transmit the current signal; wherein, the establishment of the preset condition at least includes: within a preset time before transmitting the current signal, The target transmission resource transmits the previous signal.
本发明实施例的信号传输方法既可适用于UE使用非授权频段的资源发送上行信号的应用场景，也可适用于网络侧设备使用非授权频段的资源发送下行信号的应用场景。The signal transmission method of the embodiment of the present invention can be applied to the application scenario in which the UE sends uplink signals using the resources of the unlicensed frequency band, and can also be applied to the application scenario in which the network side equipment sends the downlink signals using the resources of the unlicensed frequency band.
当前信号为上行信号时，在先信号可以是上行信号，也可以是下行信号。相应的，当前信号为下行信号时，在先信号可以是上行信号，也可以是下行信号。When the current signal is an uplink signal, the previous signal may be an uplink signal or a downlink signal. Correspondingly, when the current signal is a downlink signal, the previous signal may be an uplink signal or a downlink signal.
如图3所示，在t2时间节点对应的传输资源A和传输资源B中，传输资源A在t1时间节点传输过在先信号，t1至t2的时间间隔小于或等于预设时间，则在t2时间节点，传输资源A可以认为是不用做LBT的传输资源，则通信设备可优先选择传输资源A，并直接使用传输资源A进行信号的传输。As shown in Figure 3, in the transmission resource A and transmission resource B corresponding to the time node t2 , the transmission resource A has transmitted the previous signal at the time node t1 , and the time interval from t1 to t2 is less than or equal to the preset time , then at timet2 , transmission resource A can be considered as a transmission resource that does not need to be used for LBT, and the communication device can preferentially select transmission resource A and directly use transmission resource A for signal transmission.
本发明实施例中，通信设备若需要在某个时间节点传输当前信号，则通信设备可以从该时间节点对应的传输资源中随机选择一个传输资源，判断所选择的传输资源是否满足预设条件，若满足，则直接使用该传输资源传输信号；否则对该传输资源进行LBT，若LBT成功，则使用该传输资源传输信号，否则从剩下的传输资源中继续选择，并重复以上过程。In the embodiment of the present invention, if the communication device needs to transmit the current signal at a certain time node, the communication device may randomly select a transmission resource from the transmission resources corresponding to the time node, and judge whether the selected transmission resource satisfies the preset condition, If satisfied, directly use the transmission resource to transmit the signal; otherwise, perform LBT on the transmission resource, if the LBT is successful, use the transmission resource to transmit the signal, otherwise continue to select from the remaining transmission resources, and repeat the above process.
从统计学方面来看，上述信号传输的过程在一定的概率上可以减少通信设备在非授权频段的通信过程中进行LBT的次数，从而在一定的概率上可以减少通信设备在非授权频段的资源空闲检测上消耗的电能。From a statistical point of view, the above signal transmission process can reduce the number of LBTs performed by the communication device in the communication process of the unlicensed frequency band with a certain probability, thereby reducing the resources of the communication device in the unlicensed frequency band with a certain probability. Power consumed on idle detection.
以上信号传输的过程仅为示例，本发明实施例对此不作限定。The above signal transmission process is only an example, which is not limited in this embodiment of the present invention.
本发明实施例中，在通信设备进行信号传输前的较短的时间内，如果某个属于非授权频段的传输资源传输过在先信号，则通信设备可以直接使用该传输资源进行信号传输，而不需要对该传输资源进行LBT。这样，可以减少通信设备在非授权频段的通信过程中进行LBT的次数，从而可以减少通信设备在非授权频段的资源空闲检测上消耗的电能。In the embodiment of the present invention, in a short period of time before the communication device performs signal transmission, if a certain transmission resource belonging to an unlicensed frequency band transmits a previous signal, the communication device can directly use the transmission resource for signal transmission, and No LBT is required for this transmission resource. In this way, the number of times that the communication device performs LBT in the communication process in the unlicensed frequency band can be reduced, thereby reducing the power consumption of the communication device in the detection of resource idleness in the unlicensed frequency band.
本发明具体实施例中，预设条件成立可以仅与信号传输的时间相关，即只要在传输所述当前信号之前的预设时间内，所述目标传输资源传输过在先信号，即可认为该目标传输资源无需进行LBT操作。In the specific embodiment of the present invention, the establishment of the preset condition may only be related to the time of signal transmission, that is, as long as the target transmission resource transmits the previous signal within the preset time before the transmission of the current signal, it can be considered that the target transmission resource has transmitted the previous signal. The target transport resource does not require LBT operation.
但从传输的可靠性、传输的重要程度等方面考虑，本发明具体实施例中还可以对预设条件使用额外的参数进行限制，以满足业务需求。如本发明具体实施例中，所述预设条件还可以通过所述在先信号的传输参数和/或所述当前信号的传输参数来进一步约束，即：所述预设条件还可以与在先信号的传输参数和/或所述当前信号的传输参数相关。However, considering the reliability of transmission, the importance of transmission, etc., in the specific embodiment of the present invention, additional parameters may be limited to the preset conditions to meet service requirements. As in the specific embodiment of the present invention, the preset condition may be further constrained by the transmission parameter of the previous signal and/or the transmission parameter of the current signal, that is, the preset condition may also be related to the previous signal.

方式一：从备选传输资源中随机选择一个传输资源，判断所选择的传输资源是否满足预设条件，若满足，则直接使用该传输资源传输信号；否则继续随机选择一个传输资源进行判断，直至找到满足预设条件的传输资源，并直接使用满足预设条件的传输资源传输信号。若全部传输资源均不满足预设条件，则随机选择一个传输资源进行LBT，若LBT成功，则使用该传输资源传输信号，否则继续选择并重复以上过程。Mode 1: Randomly select a transmission resource from the alternative transmission resources, and judge whether the selected transmission resource satisfies the preset condition, and if so, directly use the transmission resource to transmit the signal; otherwise, continue to randomly select a transmission resource for judgment until Find the transmission resources that meet the preset conditions, and directly use the transmission resources that meet the preset conditions to transmit signals. If all the transmission resources do not meet the preset conditions, randomly select a transmission resource for LBT, if the LBT is successful, use the transmission resource to transmit the signal, otherwise continue to select and repeat the above process.
方式二：按照一定的顺序从备选传输资源中选择一个传输资源，判断所选择的传输资源是否满足预设条件，若满足，则直接使用该传输资源传输信号；否则对下一个传输资源进行判断，直至找到满足预设条件的传输资源，并直接使用满足预设条件的传输资源传输信号。若全部传输资源均不满足预设条件，则随机选择一个传输资源进行LBT，若LBT成功，则使用该传输资源传输信号，否则继续选择并重复以上过程。Mode 2: Select a transmission resource from the alternative transmission resources according to a certain order, and judge whether the selected transmission resource satisfies the preset condition, if so, directly use the transmission resource to transmit the signal; otherwise, judge the next transmission resource , until a transmission resource that satisfies the preset condition is found, and the signal is directly transmitted using the transmission resource that satisfies the preset condition.

例如，PRACH资源1和PRACH资源2同时满足预设条件，而PRACH资源1对应的下行CSI-RS或SSB的RSRP(Reference Symbol Received Power，参考符号接收强度)的测量结果更好，则UE可优先选择PRACH资源1作为目标传输资源。For example, if PRACH resource 1 and PRACH resource 2 meet the preset conditions at the same time, and the downlink CSI-RS corresponding to PRACH resource 1 or the RSRP (Reference Symbol Received Power, Reference Symbol Received Power) measurement result of the SSB corresponding to PRACH resource 1 is better, the UE can give priority to Select PRACH resource 1 as the target transmission resource.
示例二：从满足预设条件的多个(包括两个)下行传输资源中，选择下行传输资源对应的下行测量结果最好或较好的下行传输资源作为目标传输资源，用于下行信号的发送。Example 2: From multiple (including two) downlink transmission resources that meet the preset conditions, select the downlink transmission resource with the best or better downlink measurement result corresponding to the downlink transmission resource as the target transmission resource for sending downlink signals .
例如，PDCCH资源1和PDCCH资源2同时满足预设条件，而PDCCH资源1对应的下行CSI-RS或SSB的RSRP的测量结果更好，则网络侧设备可优先选择PDCCH资源1作为目标传输资源。For example, if PDCCH resource 1 and PDCCH resource 2 meet the preset conditions at the same time, and the measurement result of downlink CSI-RS or SSB RSRP corresponding to PDCCH resource 1 is better, the network side device can preferentially select PDCCH resource 1 as the target transmission resource.
以上根据测量结果选择目标传输资源的方式仅为示例，本发明实施例对此不作限定。The foregoing manner of selecting the target transmission resource according to the measurement result is merely an example, which is not limited in this embodiment of the present invention.
如图4所示，在t2时间节点对应的备选传输资源中，传输资源C和传输资源D为不用做LBT的传输资源，则通信设备可从传输资源C和传输资源D中随机选择其中一个传输资源；也可根据测量结果选择，从传输资源C和传输资源D中选择测量结果较好的传输资源。As shown in FIG. 4 , among the candidate transmission resources corresponding to the node at time t2 , transmission resource C and transmission resource D are transmission resources that do not need to be used for LBT, and the communication device can randomly select the transmission resource C and transmission resource D among them. A transmission resource; it can also be selected according to the measurement result, and a transmission resource with a better measurement result can be selected from transmission resource C and transmission resource D.

以下针对UE使用非授权频段的资源发送上行信号，和，网络侧设备使用非授权频段的资源发送下行信号这两种应用场景，对上述通过MAC层选择目标传输资源的过程进行具体说明。The following describes the above process of selecting target transmission resources through the MAC layer for two application scenarios: the UE uses the resources of the unlicensed frequency band to send the uplink signal, and the network side equipment uses the resources of the unlicensed frequency band to send the downlink signal.
UE在触发上行信号发送的时候，MAC层选择多个上行发送资源位置，例如，资源1：PRACH资源在频点1和子帧2；资源2：PRACH资源在频点2和子帧2；资源3：PRACH资源在频点3和子帧3。上述多个上行发送资源位置可通过网络侧设备配置或经协议约定。When the UE triggers uplink signal transmission, the MAC layer selects multiple uplink transmission resource locations, for example, resource 1: PRACH resource at frequency 1 and subframe 2; resource 2: PRACH resource at frequency 2 and subframe 2; resource 3: PRACH resources are in frequency point 3 and subframe 3.

相应的，网络侧设备在触发下行信号发送的时候，MAC层选择多个下行发送资源位置，例如，资源1：PDCCH资源在频点1和子帧2；资源2：PDCCH资源在频点2和子帧2；资源3：PDCCH资源在频点3和子帧3。上述多个下行发送资源位置可通过网络侧设备配置或经协议约定。Correspondingly, when the network-side device triggers downlink signal transmission, the MAC layer selects multiple downlink transmission resource locations, for example, resource 1: PDCCH resource at frequency point 1 and subframe 2; resource 2: PDCCH resource at frequency point 2 and subframe 2; Resource 3: PDCCH resources are in frequency point 3 and subframe 3. The above-mentioned multiple downlink sending resource locations may be configured by a network side device or agreed upon in a protocol.
MAC层判断在上述多个下行发送资源中，是否满足预设条件的下行发送资源，若存在满足预设条件的下行发送资源，MAC层优先选择该下行发送资源。例如，资源1：PDCCH资源在频点1和子帧2，而网络侧设备在频点1子帧1收到了上行信道PUCCH信号，则MAC层优先选择该资源1用于PDCCH的发送。The MAC layer judges whether there is a downlink transmission resource that satisfies a preset condition among the above-mentioned multiple downlink transmission resources, and if there is a downlink transmission resource that satisfies the preset condition, the MAC layer preferentially selects the downlink transmission resource. For example, resource 1: the PDCCH resource is in frequency 1 and subframe 2, and the network side device receives the uplink channel PUCCH signal in subframe 1 of frequency 1, the MAC layer preferentially selects this resource 1 for PDCCH transmission.
MAC层将选择的下行发送资源指示给PHY层用于下行信号的发送。The MAC layer indicates the selected downlink transmission resource to the PHY layer for transmission of downlink signals.
额外的，当多个下行发送资源同时满足预设条件的时候，MAC层随机选择一个可用的下行发送资源用于下行信号的发送，或从多个下行发送资源中选择下行发送资源对应的下行测量最好的下行发送资源。In addition, when multiple downlink transmission resources meet the preset conditions at the same time, the MAC layer randomly selects an available downlink transmission resource for downlink signal transmission, or selects the downlink measurement corresponding to the downlink transmission resource from the multiple downlink transmission resources.

以下针对UE使用非授权频段的资源发送上行信号，和，网络侧设备使用非授权频段的资源发送下行信号这两种应用场景，对上述通过PHY层选择目标传输资源的过程进行具体说明。The following describes the above process of selecting target transmission resources through the PHY layer for two application scenarios: the UE uses the resources of the unlicensed frequency band to send uplink signals, and the network side equipment uses the resources of the unlicensed frequency band to send the downlink signals.
UE在触发上行信号发送的时候，MAC层向PHY层指示多个上行发送资源，例如，资源1：PRACH资源在频点1和子帧2；资源2：PRACH资源在频点2和子帧2；资源3：PRACH资源在频点3和子帧3。上述多个上行发送资源位置可通过网络侧设备配置或经协议约定。When the UE triggers uplink signal transmission, the MAC layer indicates multiple uplink transmission resources to the PHY layer, for example, resource 1: PRACH resource at frequency point 1 and subframe 2; resource 2: PRACH resource at frequency point 2 and subframe 2; resource 3: PRACH resources are in frequency point 3 and subframe 3. The above-mentioned multiple uplink sending resource locations may be configured by a network side device or agreed upon in a protocol.
PHY层判断在该MAC层指示的多个上行发送资源中，是否存在满足预设条件的上行发送资源，若存在满足预设条件的上行发送资源，PHY层优先选择该上行发送资源用于上行信号的发送。例如，资源1：PRACH资源在频点1和子帧2，而UE在频点1子帧1收到了下行信道PDCCH信号，则PHY层优先选择该资源1用于PRACH的发送。The PHY layer determines whether there is an uplink transmission resource that meets the preset condition among the multiple uplink transmission resources indicated by the MAC layer. If there is an uplink transmission resource that meets the preset condition, the PHY layer preferentially selects the uplink transmission resource for uplink signals. of sending. For example, resource 1: The PRACH resource is in frequency point 1 and subframe 2, and the UE receives the downlink channel PDCCH signal in subframe 1 of frequency point 1, and the PHY layer preferentially selects this resource 1 for PRACH transmission.
额外的，当多个上行发送资源同时满足预设条件的时候，PHY层随机选择一个可用的上行发送资源用于上行信号的发送，或从多个上行发送资源中选择上行发送资源对应的下行测量最好的上行发送资源用于上行信号的发送。In addition, when multiple uplink transmission resources meet the preset conditions at the same time, the PHY layer randomly selects an available uplink transmission resource for uplink signal transmission, or selects the downlink measurement corresponding to the uplink transmission resource from multiple uplink transmission resources. The best uplink transmission resources are used for the transmission of uplink signals.
相应的，网络侧设备在触发下行信号发送的时候，MAC层向PHY层指示多个下行发送资源，例如，资源1：PDCCH资源在频点1和子帧2；资源2：PDCCH资源在频点2和子帧2；资源3：PDCCH资源在频点3和子帧3。上述多个下行发送资源位置可通过网络侧设备配置或经协议约定。Correspondingly, when the network-side device triggers downlink signal transmission, the MAC layer indicates multiple downlink transmission resources to the PHY layer, for example, resource 1: PDCCH resources at frequency point 1 and subframe 2; resource 2: PDCCH resources at frequency point 2 and subframe 2; resource 3: PDCCH resources are in frequency point 3 and subframe 3. The above-mentioned multiple downlink sending resource locations may be configured by a network side device or agreed upon in a protocol.
PHY层判断在该MAC层指示的多个下行发送资源中，是否存在满足预设条件的下行发送资源，若存在满足预设条件的下行发送资源，PHY层优先选择该下行发送资源用于下行信号的发送。例如，资源1：PDCCH资源在频点1和子帧2，而网络侧设备在频点1子帧1收到了上行信道PUCCH信号，则PHY层优先选择该资源1用于PDCCH的发送。The PHY layer determines whether there is a downlink transmission resource that meets the preset condition among the multiple downlink transmission resources indicated by the MAC layer, and if there is a downlink transmission resource that meets the preset condition, the PHY layer preferentially selects the downlink transmission resource for the downlink signal of sending. For example, resource 1: the PDCCH resource is in frequency point 1 and subframe 2, and the network side device receives the uplink channel PUCCH signal in subframe 1 of frequency point 1, the PHY layer preferentially selects this resource 1 for PDCCH transmission.
额外的，当多个下行发送资源同时满足预设条件的时候，PHY层随机选择一个可用的下行发送资源用于下行信号的发送，或从多个下行发送资源中选择下行发送资源对应的下行测量最好的下行发送资源用于下行信号的发送。In addition, when multiple downlink transmission resources meet the preset conditions at the same time, the PHY layer randomly selects an available downlink transmission resource for downlink signal transmission, or selects the downlink measurement corresponding to the downlink transmission resource from the multiple downlink transmission resources. The best downlink transmission resources are used for downlink signal transmission.
综合上述可知，在通信设备进行信号传输前的较短的时间内，如果某个属于非授权频段的传输资源传输过在先信号，则通信设备可以直接使用该传输资源进行信号传输，而不需要对该传输资源进行LBT。此外，通信设备还可以在备选传输资源中优先选择不需要进行LBT的传输资源进行信号的传输。这样，可以减少通信设备在非授权频段的通信过程中进行LBT的次数，从而可以减少通信设备在非授权频段的资源空闲检测上消耗的电能。Based on the above, it can be seen that in a short period of time before the communication device performs signal transmission, if a certain transmission resource belonging to an unlicensed frequency band transmits a previous signal, the communication device can directly use the transmission resource for signal transmission without the need for LBT is performed on the transmission resource. In addition, the communication device may also preferentially select a transmission resource that does not require LBT from among the alternative transmission resources for signal transmission. In this way, the number of times that the communication device performs LBT in the communication process in the unlicensed frequency band can be reduced, thereby reducing the power consumption of the communication device in the detection of resource idleness in the unlicensed frequency band.

本发明实施例中，在通信设备进行信号传输前的较短的时间内，如果某个属于非授权频段的传输资源传输过在先信号，则通信设备可以直接使用该传输资源进行信号传输，而不需要对该传输资源进行LBT。此外，通信设备还可以在备选传输资源中优先选择不需要进行LBT的传输资源进行信号的传输。这样，可以减少通信设备在非授权频段的通信过程中进行LBT的次数，从而可以减少通信设备在非授权频段的资源空闲检测上消耗的电能。In the embodiment of the present invention, in a short period of time before the communication device performs signal transmission, if a certain transmission resource belonging to an unlicensed frequency band transmits a previous signal, the communication device can directly use the transmission resource for signal transmission, and No LBT is required for this transmission resource. In addition, the communication device may also preferentially select a transmission resource that does not require LBT from among the alternative transmission resources for signal transmission. In this way, the number of times that the communication device performs LBT in the communication process in the unlicensed frequency band can be reduced, thereby reducing the power consumption of the communication device in the detection of resource idleness in the unlicensed frequency band.
