Description

信道处理方法及相关设备Channel processing method and related equipment

技术领域Technical field

本申请涉及通信技术领域，尤其涉及一种信道处理方法及相关设备。The present application relates to the field of communications technologies, and in particular, to a channel processing method and related devices.

背景技术Background technique

目前，在发送数据之前，需要先监听信道是否空闲，该机制也可以称为信道空闲检测(Clear Channel Assessment，CCA)。请参阅图1，图1是一种信道检测方法的示意图，用户设备UE2要建立通信链路时，先要全向监听信道是否空闲，但此时UE1正在发送数据，UE1处于UE2的CCA半径内，导致UE2监听到的信道能量值大于干扰阈值，从而无法建立通信链路。Currently, before sending data, it is necessary to first monitor whether the channel is idle. This mechanism can also be called Clear Channel Assessment (CCA). Please refer to FIG. 1. FIG. 1 is a schematic diagram of a channel detection method. When a user equipment UE2 establishes a communication link, it is necessary to firstly monitor whether the channel is idle, but at this time, UE1 is transmitting data, and UE1 is within the CCA radius of UE2. The channel energy value monitored by the UE2 is greater than the interference threshold, so that the communication link cannot be established.

可见，只要在发射端的覆盖范围内有其他终端或基站发送数据时，都会导致CCA获得的信道能量值大于干扰阈值，而无法建立通信链路，导致网络容量较小。It can be seen that as long as other terminals or base stations transmit data within the coverage of the transmitting end, the channel energy value obtained by the CCA is greater than the interference threshold, and the communication link cannot be established, resulting in a small network capacity.

发明内容Summary of the invention

本申请提供一种信道处理方法及相关设备，能够增加共存的通信链路，从而增大网络容量。The present application provides a channel processing method and related equipment, which can increase a coexistence communication link, thereby increasing network capacity.

一方面，本申请提供一种信道处理方法，该信道处理方法中，第一设备确定监听波束集合，在该监听波束集合中的每个监听波束上执行信道空间检测，获得每个监听波束上的信道能量值，第一设备根据每个监听波束上的信道能量值从监听波束集合中确定监听波束子集，该监听波束子集中每个监听波束的信道能量值小于干扰阈值，其中，监听波束集合包括K ₁个监听波束，所述K ₁为大于1的整数。 In one aspect, the present application provides a channel processing method, in which a first device determines a set of listening beams, performs channel space detection on each of the monitoring beams in the set of monitoring beams, and obtains on each of the monitoring beams. a channel energy value, the first device determines, according to the channel energy value on each of the monitoring beams, a subset of the monitoring beam from the set of monitoring beams, wherein the channel energy value of each of the monitoring beam subsets is smaller than an interference threshold, wherein the monitoring beam set A K ₁ listening beam is included, and K ₁ is an integer greater than 1.

可见，该实施方式通过多个监听波束执行信道空间检测，避免第一设备处于其他设备的通信链路中而检测到信道被占用无法建立通信链路的问题，也就是说，该实施方式可以舍弃旁瓣干扰超过干扰阈值的波束方向，得到干扰小的波束方向，从而使得第一设备能够利用这些干扰小的波束方向建立通信链路，与现有的全向监听信道的方式相比，能够大大的提升网络容量。It can be seen that the implementation of the channel space detection by using multiple monitoring beams avoids the problem that the first device is in the communication link of other devices and detects that the channel is occupied and cannot establish a communication link, that is, the implementation can be discarded. The side-lobe interference exceeds the beam direction of the interference threshold, and the beam direction with small interference is obtained, so that the first device can establish the communication link by using the beam direction with small interference, which can be greatly compared with the existing omnidirectional channel. Increase network capacity.

在一种实施方式中，该信道处理方法还可以包括：第一设备确定训练波束集合，所述训练波束集合包括K ₂个训练波束，所述K ₂为大于1的整数；第一设备根据波束间的相关性以及所述监听波束子集从所述训练波束集合中确定用于发送请求发送数据(Request To Send，RTS)的训练波束子集。该实施方式根据监听波束子集从训练波束集合中确定用于发送RTS的训练波束子集，可以减少训练波束过程中的波束扫描次数。 In an embodiment, the channel processing method may further include: the first device determines a training beam set, the training beam set includes K ₂ training beams, and the K ₂ is an integer greater than 1; the first device is configured according to the beam The correlation between the monitoring and the subset of the monitoring beams determines a subset of training beams for transmitting Request To Send (RTS) from the set of training beams. The embodiment determines the training beam subset for transmitting the RTS from the training beam set according to the monitoring beam subset, and can reduce the number of beam scanning times in the training beam process.

在一种实施方式中，该信道处理方法还可以包括：第一设备在所述训练波束子集中的每个训练波束上发送RTS，以使第二设备在所述RTS的发送周期内确定第二设备的训练波束集合中每个波束上的参考信号接收功率RSRP，以及根据所述每个波束上的RSRP从所述第二设备的训练波束集合中确定请求发送波束集合；其中，该请求发送波束集合中可以选取RSRP最大的前N个波束构成。In an embodiment, the channel processing method may further include: the first device transmitting the RTS on each training beam in the training beam subset, so that the second device determines the second in the sending period of the RTS. a reference signal on each beam in the training beam set of the device receives the power RSRP, and determines a request transmission beam set from the training beam set of the second device according to the RSRP on each beam; wherein the request transmission beam The first N beams of the largest RSRP can be selected in the set.

其中，所述请求发送波束集合与所述第二设备的监听波束子集的交集作为用于发送允许发送数据(Clear To Send，CTS)的波束集合，所述第二设备的监听波束子集是所述第二设备针对所述第二设备的监听波束集合中的每个波束进行信道空闲检测获得的；所述第二设备的训练波束集合包括M ₂个训练波束，所述第二设备的监听波束集合包括M ₁个监听波束，所述M ₁和所述M ₂均为大于1的整数。该实施方式中，第二设备也可以将信道监听与波束训练相结合，从请求发送波束集合中进一步的确定能够发送CTS的波束集合，从而避免接收端，即第二设备，处于其他通信链路而不能检测到信道被占用而建立通信链路的情况。 The intersection of the request transmission beam set and the monitoring device subset of the second device is used as a beam set for transmitting Clear To Send (CTS), and the monitoring device subset of the second device is Obtaining, by the second device, channel idle detection for each beam in the monitoring beam set of the second device; the training beam set of the second device includes M ₂ training beams, and the monitoring of the second device The beam set includes M ₁ listening beams, and both M ₁ and M ₂ are integers greater than one. In this implementation manner, the second device may also combine channel monitoring with beam training, and further determine, from the set of request transmission beams, a beam set capable of transmitting the CTS, thereby preventing the receiving end, that is, the second device, from being in other communication links. It is not possible to detect that a channel is occupied to establish a communication link.

在一种实施方式中，该信道处理方法还可以包括：第一设备在所述CTS的发送周期内确定所述训练波束子集中每个波束的RSRP；第一设备根据所述训练波束子集中每个波束的RSRP以及所述训练波束子集确定允许发送波束集合。其中，该允许发送波束集合中可以选取RSRP最大的P对收发波束。In an embodiment, the channel processing method may further include: determining, by the first device, an RSRP of each beam in the training beam subset in a sending period of the CTS; the first device according to each of the training beam subsets The RSRP of the beams and the subset of training beams determine the set of allowed transmit beams. The P-pair transceiver beam with the largest RSRP can be selected in the allowed transmission beam set.

可见，该实施方式确定的允许发送波束集合中，每个波束均为干扰较小、信道质量较好的收发波束，因此，可以将允许发送波束集合中RSRP最大的波束作为当前通信波束，将其余的波束作为备选波束。It can be seen that each of the allowed transmit beam sets determined by the embodiment is a transmit and receive beam with less interference and better channel quality. Therefore, the beam with the largest RSRP in the transmit beam set can be used as the current communication beam, and the rest. The beam is used as an alternative beam.

在一种实施方式中，所述K ₁小于所述K ₂；所述M ₁小于所述M ₂，即第一设备和第二设备所用的监听波束集合中监听波束的个数要小于训练波束集合中训练波束的个数，即监听波束集合采用粗波束，训练波束集合采用实际通信用的细波束，此时监听信道的波束比发送RTS/CTS的训练波束要宽，这样，粗波束做信道监听可以减少监听时段的波束扫描次数和时延开销。 In an embodiment, the K _{1 is} smaller than the K ₂ ; the M _{1 is} smaller than the M ₂ , that is, the number of the monitoring beams in the monitoring beam set used by the first device and the second device is smaller than the training beam. The number of training beams in the set, that is, the monitoring beam set adopts a coarse beam, and the training beam set adopts a thin beam for actual communication. At this time, the beam of the monitoring channel is wider than the training beam for transmitting the RTS/CTS, so that the thick beam is used as a channel. Monitoring can reduce the number of beam scans and latency of the listening period.

在另一种实施方式中，所述K ₁等于所述K ₂；所述M ₁等于所述M ₂，即第一设备和第二设备所用的监听波束集合中监听波束的个数要等于训练波束集合中训练波束的个数，即监听波束集合和训练波束集合均采用实际通信用的细波束，这样，虽然相比粗波束做信道监听，细波束增加了监听时段的波束扫描次数和时延开销，但能够实现网络容量的大大增加。 In another embodiment, the K ₁ is equal to the K ₂ ; the M ₁ is equal to the M ₂ , that is, the number of the monitoring beams in the monitoring beam set used by the first device and the second device is equal to the training. The number of training beams in the beam set, that is, the monitoring beam set and the training beam set are all used for the fine beam for actual communication, so that although the channel monitoring is performed compared to the coarse beam, the beamlet increases the beam scanning times and delays of the listening period. Overhead, but can achieve a significant increase in network capacity.

总之，该信道处理方法联合实现信道监听和波束悬链过程，避免重复进行波束扫描，降低信令和时延开销，提高处理效率的同时降低了波束扫描配对的复杂度。In summary, the channel processing method jointly implements channel monitoring and beam hangover processes, avoids repeated beam scanning, reduces signaling and delay overhead, improves processing efficiency, and reduces beam scanning pairing complexity.

另一方面，本申请还提供一种信道处理方法，该信道处理方法中，第二设备在请求发送数据RTS的发送周期内，确定训练波束集合中每个波束上的参考信号接收功率(Reference Signal Receiving Power，RSRP)；第二设备根据所述每个波束上的参考信号接收功率RSRP从所述训练波束集合中确定请求发送波束集合，所述请求发送波束集合为所述训练波束集合的子集；第二设备在监听波束集合中的每个监听波束上执行信道空间检测，获得每个监听波束上的信道能量值；第二设备根据所述每个监听波束上的信道能量值从所述监听波束集合中确定监听波束子集，所述监听波束子集中每个监听波束的信道能量值小于干扰阈值。第二设备确定所述请求发送波束集合与所述监听波束子集的交集，将所述交集作为用于发送允许发送数据CTS的波束集合。On the other hand, the present application further provides a channel processing method, in which a second device determines a reference signal received power on each beam in a training beam set in a transmission period of a request for transmitting data RTS (Reference Signal Receiving Power (RSRP); the second device determines a request transmission beam set from the training beam set according to the reference signal received power RSRP on each beam, the request transmission beam set being a subset of the training beam set The second device performs channel space detection on each of the monitoring beams in the monitoring beam set to obtain a channel energy value on each of the monitoring beams; the second device monitors the channel energy value from each of the monitoring beams from the monitoring A subset of the monitoring beams is determined in the set of beams, and a channel energy value of each of the monitoring beams in the subset of the monitoring beams is less than an interference threshold. The second device determines an intersection of the request transmission beam set and the monitoring beam subset, and uses the intersection as a beam set for transmitting the allowable transmission data CTS.

其中，所述训练波束集合包括M ₂个训练波束，所述监听波束集合包括M ₁个监听波束，所述M ₁和所述M ₂均为大于1的整数。 The training beam set includes M ₂ training beams, the monitoring beam set includes M ₁ monitoring beams, and the M ₁ and the M ₂ are integers greater than 1.

其中，第二设备确定的请求发送波束集合可以选取最大RSRP的前N个波束。The request sending beam set determined by the second device may select the first N beams of the maximum RSRP.

可见，该实施方式中，第二设备还可以通过信道监听获得干扰比较小的监听波束子集，根据监听波束子集和请求发送波束集合相结合，获得允许发送CTS的波束集合，从而避免第二设备处于其他通信链路而不能检测到信道被占用而建立通信链路的情况。It can be seen that, in this implementation manner, the second device can also obtain a subset of the monitoring beam with less interference by channel monitoring, and obtain a beam set that allows the CTS to be transmitted according to the monitoring beam subset and the request transmitting beam set, thereby avoiding the second The device is on other communication links and cannot detect that the channel is occupied to establish a communication link.

具体实施方式detailed description

本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。The terms used in the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

为便于频谱共享，请参见图1，图1是本申请实施例提供的一种LBT监听的原理图，如图1所示，设备在接入信道时应执行发送前监听(Listen Before Talk,LBT)，LBT监听是指设备在接入信道时，需要先进行信道空闲检测(Clear Channel Assessment，CCA)，如果检测的信道能量值低于干扰阈值或者CCA门限，则表示该信道空闲，然而，现有技术中是采用全向监听所覆盖范围内的信道是否有干扰，假设干扰小于CCA门限时，才可建立通信链路，来传送数据。请参阅图2，图2是一种全向LBT监听的示意图，如图2所示，用于设备(User Equipment,UE)2要建立通信链路时，先要全向监听信道是否空闲，此时若UE1正在向gNB1发送数据，由于UE1处于UE2的CCA半径内，UE2覆盖范围内的信道能量大于干扰阈值，则不能建立UE2与gNB2之间的通信链路。For the sake of spectrum sharing, please refer to FIG. 1. FIG. 1 is a schematic diagram of an LBT monitoring provided by an embodiment of the present application. As shown in FIG. 1 , a device should perform a pre-transmission monitoring (Listen Before Talk, LBT) when accessing a channel. LBT monitoring means that when the device accesses the channel, it needs to perform Clear Channel Assessment (CCA) first. If the detected channel energy value is lower than the interference threshold or the CCA threshold, it indicates that the channel is idle, however, In the prior art, whether the channel covered by the omnidirectional monitoring has interference is used, and if the interference is less than the CCA threshold, the communication link can be established to transmit data. Referring to FIG. 2, FIG. 2 is a schematic diagram of omnidirectional LBT monitoring. As shown in FIG. 2, when a device (User Equipment, UE) 2 needs to establish a communication link, it is necessary to firstly monitor whether the channel is idle. If UE1 is transmitting data to gNB1, since UE1 is within the CCA radius of UE2 and the channel energy within the coverage of UE2 is greater than the interference threshold, the communication link between UE2 and gNB2 cannot be established.

可见，现有的全向LBT无法判断干扰方向，难以区分有效干扰和无效干扰，极易造成误判，从而减少网络中的共存链路数，降低了网络容量。It can be seen that the existing omnidirectional LBT cannot judge the interference direction, and it is difficult to distinguish between effective interference and invalid interference, which is easy to cause misjudgment, thereby reducing the number of coexisting links in the network and reducing the network capacity.

为了解决该问题，本申请提供一种信道处理方法，该信道处理方法中，可以确定监听波束集合，监听波束集合包括K ₁个监听波束，所述K ₁为大于1的整数；在所述监听波束集合中的每个监听波束上执行信道空间检测，获得每个监听波束上的信道能量值；第一设备根据所述每个监听波束上的信道能量值从所述监听波束集合中确定监听波束子集，所述监听波束子集中每个监听波束的信道能量值小于干扰阈值。 In order to solve the problem, the present application provides a channel processing method, in which a monitoring beam set can be determined, the monitoring beam set includes K ₁ monitoring beams, and the K ₁ is an integer greater than 1; Channel space detection is performed on each of the monitoring beams to obtain a channel energy value on each of the monitoring beams; the first device determines the monitoring beam from the set of monitoring beams according to the channel energy value on each of the sensing beams The subset, the channel energy value of each of the monitoring beams in the subset of the monitoring beams is less than an interference threshold.

下面结合更多的附图，对本申请实施例的方案进行说明。The solution of the embodiment of the present application will be described below with reference to more drawings.

请参见图3，图3是本申请实施例提供的一种信道处理方法的流程示意图，如图1所示，该信道处理方法可以包括如下步骤：Referring to FIG. 3, FIG. 3 is a schematic flowchart of a channel processing method according to an embodiment of the present disclosure. As shown in FIG. 1, the channel processing method may include the following steps:

101、第一设备确定监听波束集合，所述监听波束集合包括K ₁个监听波束，所述K ₁为大于1的整数； 101. The first device determines a monitoring beam set, where the monitoring beam set includes K ₁ monitoring beams, where K ₁ is an integer greater than 1.

102、第一设备在所述监听波束集合中的每个监听波束上执行信道空间检测，获得每个监听波束上的信道能量值；102. The first device performs channel space detection on each of the monitoring beam sets to obtain a channel energy value on each of the monitoring beams.

103、第一设备根据所述每个监听波束上的信道能量值从所述监听波束集合中确定监听波束子集，所述监听波束子集中每个监听波束的信道能量值小于干扰阈值。103. The first device determines, according to the channel energy value on each of the monitoring beams, a subset of the monitoring beams from the set of monitoring beams, where a channel energy value of each of the monitoring beams is smaller than an interference threshold.

例如，可以根据第一设备的天线情况为该第一设备定义监听波束集合B _TL＝{T _L1,T _L2,…,T _LK1}，以及RTS发送或CTS接收所用的训练波束集合B _TT＝{T _T1,T _T2,…,T _TK2}。第一设备可以在监听波束集合中的每个T _Li(i＝1……K ₁)上进行CCA探测。 For example, the monitoring beam set B _TL ={T _L1 , T _L2 , . . . , T _LK1 } may be defined for the first device according to the antenna condition of the first device, and the training beam set B _TT = { used for RTS transmission or CTS reception. T _T1 , T _T2 ,..., T _TK2 }. The first device may perform CCA detection on each of the T _Li (i = 1 ... K ₁ ) in the set of listening beams.

例如，请参见图4，图4是本申请实施例提供的一种暴露节点的示意图，如图4所示，UE2处于UE1与gNB1之间的通信链路上，UE2可以通过该实施方式在灰色阴影的波束方向上检测到干扰较小的信道，故UE2可以在该灰色阴影的波束方向上建立通信链路。因此，与全向LBT监听相比，该实施方式可以增加网路中通信链路的数量，从而提升网络容量。For example, please refer to FIG. 4. FIG. 4 is a schematic diagram of an exposed node according to an embodiment of the present disclosure. As shown in FIG. 4, UE2 is in a communication link between UE1 and gNB1, and UE2 can be grayed by this embodiment. A less disturbing channel is detected in the shaded beam direction, so UE2 can establish a communication link in the gray shaded beam direction. Therefore, compared to omnidirectional LBT snooping, this implementation can increase the number of communication links in the network, thereby increasing network capacity.

在一种实施方式中，请参阅图5，图5是本申请实施例提供的另一种信道处理方法的流程示意图，如图5所示，该信道处理方法与图3所示的信道处理方法相比，还可以包括以下步骤：In an embodiment, please refer to FIG. 5. FIG. 5 is a schematic flowchart of another channel processing method according to an embodiment of the present disclosure. As shown in FIG. 5, the channel processing method and the channel processing method shown in FIG. In comparison, it can also include the following steps:

104、第一设备确定训练波束集合，所述训练波束集合包括K ₂个训练波束，所述K ₂为大于1的整数； 104. The first device determines a training beam set, where the training beam set includes K ₂ training beams, where K ₂ is an integer greater than 1.

105、第一设备根据波束间的相关性以及所述监听波束子集从所述训练波束集合中确定用于发送请求发送数据RTS的训练波束子集。105. The first device determines, according to the correlation between the beams and the monitoring beam subset, a training beam subset for transmitting the request transmission data RTS from the training beam set.

可见，该实施方式将波束训练与信道监听结合一起，可以降低训练波束集合中训练波束的扫描次数，即只需要针对训练波束子集中的训练波束进行波束扫描即可。It can be seen that the embodiment combines the beam training and the channel monitoring to reduce the number of scanning of the training beam in the training beam set, that is, only the training beam of the training beam subset needs to be beam scanned.

例如，只需针对训练波束集合B _TT＝{T _T1,T _T2,…,T _TK2}中部分训练波束进行波束扫描即可，比如，监听波束子集B _{TL_S}与B _TT的交集，并从该交集中根据波束间的相关性选择出一部分波束，生成训练波束子集B _{TT_S}。 For example, it is only necessary to perform beam scanning on a part of the training beams in the training beam set B _TT ={T _T1 , T _T2 , . . . , T _TK2 }, for example, the intersection of the monitoring beam subset B _{TL_S} and B _TT , and from the The intersection set selects a part of the beam according to the correlation between the beams, and generates a training beam subset B _{TT_S} .

在一种实施方式中，请参阅图6，图6是本申请实施例提供的另一种信道处理方法的流程示意图，如图6所示，该信道处理方法与图5所示的信道处理方法相比，该信道处理方法还可以包括以下步骤：In an embodiment, please refer to FIG. 6. FIG. 6 is a schematic flowchart of another channel processing method according to an embodiment of the present application. As shown in FIG. 6, the channel processing method and the channel processing method shown in FIG. In contrast, the channel processing method may further include the following steps:

106、第一设备在该训练波束子集中的每个训练波束上发送RTS；106. The first device sends an RTS on each training beam in the training beam subset.

比如，第一设备在训练波束子集B _{TT_S}中的每个训练波束上轮流发送RTS。 For example, the first device transmits the RTS in turn on each training beam in the training beam subset B _{TT_S} .

107、第二设备在在所述RTS的发送周期内，确定第二设备的训练波束集合中每个波束上的参考信号接收功率RSRP；107. The second device determines, in a sending period of the RTS, a reference signal received power RSRP on each beam in the training beam set of the second device.

即第二设备在训练波束子集中每个发送波束T _Ti的发送周期内，基于第二设备的训练波束集合B _RR＝{R _T1,R _T2,…,R _TM2}进行波束扫描，获得每个波束方向上的RSRP。 That is, the second device performs beam scanning based on the training beam set B _RR ={R _T1 , R _T2 , . . . , R _TM2 } of the second device in the transmission period of each transmission beam T _Ti in the training beam subset, and obtains each RSRP in the beam direction.

108、第二设备根据所述每个波束上的参考信号接收功率RSRP，从第二设备的训练波束集合中确定请求发送波束集合，所述请求发送波束集合为所述训练波束集合的子集；108. The second device determines, according to the reference signal received power RSRP on each beam, a request transmission beam set from a training beam set of the second device, where the request transmission beam set is a subset of the training beam set.

其中，该请求发送波束集合中的波束可以为RSRP最大的前N个训练波束构成，N为大于1的整数。The beam in the request transmission beam set may be the first N training beams with the largest RSRP, and N is an integer greater than 1.

109、第二设备在监听波束集合中的每个监听波束上执行信道空间检测，获得每个监听波束上的信道能量值；109. The second device performs channel space detection on each of the monitoring beams in the monitoring beam set to obtain a channel energy value on each of the monitoring beams.

110、第二设备根据所述每个监听波束上的信道能量值从所述监听波束集合中确定监听波束子集，所述监听波束子集中每个监听波束的信道能量值小于干扰阈值。110. The second device determines, according to the channel energy value on each of the monitoring beams, a subset of the monitoring beams from the set of monitoring beams, where a channel energy value of each of the monitoring beams is less than an interference threshold.

该监听波束子集舍弃了庞斑干扰超过干扰阈值的波束方向，得到受干扰小的波束集合，与全向LBT监听方式相比，可以提高网络容量。The subset of the monitoring beam discards the beam direction in which the spotting interference exceeds the interference threshold, and obtains a beam set with small interference, which can improve the network capacity compared with the omnidirectional LBT monitoring mode.

120、第二设备确定所述请求发送波束集合与所述监听波束子集的交集，将所述交集作为用于发送允许发送数据CTS的波束集合；120. The second device determines an intersection of the request transmission beam set and the monitoring beam subset, and uses the intersection as a beam set for transmitting an allowable transmission data CTS.

比如，第二设备的监听波束集合B _RL＝{R _L1,R _L2,…,R _LM1}，第二设备在发送CTS之前，还会在监听波束集合中的每个监听波束上进行信道空间检测，避免隐藏节点的问题。例如，请参阅图7，图7是本申请实施例提供的一种隐藏节点的示意图，如图7所示，隐藏节点的干扰主要源于其波束方向与当前通信链路的波束方向部分重合，现有技术中，由于UE2在进行全向CCA检测时，在CCA半径内发现信道能量值小于干扰阈值，故建立了UE2与gNB2的通信链路，但由于gNB2在gNB1与UE1的通信链路中，导致gNB1并不能准确的接收UE2发送的数据，即出现隐藏节点的问题。而采用图6所示的信道处理方法，UE2在建立通信链路之前，gNB2还需要执行109、110的操作，将会排除掉与gNB1与UE1的通信链路有重合的监听波束，即获得与gNB1与UE1的通信链路干扰小的波束集合，即监听波束子集，进而，gNB2可以结合请求发送波束集合与监听波束子集的交集获得用于发送CTS的波束集合，从而使得最终要发送CTS的波束集合中不包括与gNB1与UE1的通信链路有重合干扰大的波束，从而解决了隐藏节点的问题。 For example, if the second device has a monitoring beam set B _RL ={R _L1 , R _L2 , . . . , R _LM1 }, the second device performs channel space detection on each of the monitoring beam sets before transmitting the CTS. To avoid the problem of hiding nodes. For example, refer to FIG. 7. FIG. 7 is a schematic diagram of a hidden node according to an embodiment of the present disclosure. As shown in FIG. 7, the interference of a hidden node is mainly caused by a beam direction and a beam direction of a current communication link. In the prior art, since the UE 2 finds that the channel energy value is smaller than the interference threshold within the CCA radius when performing the omnidirectional CCA detection, the communication link between the UE2 and the gNB2 is established, but the gNB2 is in the communication link between the gNB1 and the UE1. As a result, gNB1 cannot accurately receive the data sent by UE2, that is, the problem of hidden nodes occurs. With the channel processing method shown in FIG. 6, before the UE2 establishes the communication link, the gNB2 needs to perform the operations of 109 and 110, and the interception beam that overlaps with the communication link of the gNB1 and the UE1 is excluded, that is, the obtained The communication link of gNB1 and UE1 interferes with a small beam set, that is, the monitor beam subset. Further, gNB2 can obtain the beam set for transmitting the CTS in combination with the intersection of the request transmission beam set and the monitor beam subset, so that the CTS is finally sent. The beam set does not include a beam with a large interference interference with the communication link of gNB1 and UE1, thereby solving the problem of hidden nodes.

在一种实施方式中，请参阅图8，图8是本申请实施例提供的又一种信道处理方法的流程示意图，其中，图8所示的信道处理方法与图6所示的信道处理方法相比，还可以包括以下步骤：In an embodiment, please refer to FIG. 8. FIG. 8 is a schematic flowchart of still another channel processing method according to an embodiment of the present disclosure, where the channel processing method shown in FIG. 8 and the channel processing method shown in FIG. In comparison, it can also include the following steps:

121、第二设备在上述交集中的每个波束上发送CTS；121. The second device sends a CTS on each of the beams in the intersection;

可选的，若该交集为空，则表示当前没有合适的训练波束能够发送CTS，即可以终止信道接入流程。Optionally, if the intersection is empty, it indicates that there is currently no suitable training beam capable of transmitting the CTS, that is, the channel access procedure may be terminated.

122、第一设备在所述CTS的发送周期内确定所述训练波束子集中每个波束的RSRP；122. The first device determines, according to a sending period of the CTS, an RSRP of each beam in the training beam subset.

123、第一设备根据所述训练波束子集中每个波束的RSRP以及所述训练波束子集确定允许发送波束集合。123. The first device determines, according to the RSRP of each beam in the training beam subset and the training beam subset, an allowed transmit beam set.

可见，该实施方式中，第一设备可以在105中确定的训练波束子集中每个波束上接收CTS，并记录每个波束上的RSRP，基于RSRP由大到小对收发波束对进行排序，保留RSRP最大的前P对收发波束。选取P对收发波束中RSRP最大的一对作为当前通信波束，其余P-1对作为备选波束。这样，最终获得该允许发送波束集合即为收发两端的较佳收发波束对。It can be seen that, in this implementation manner, the first device may receive the CTS on each beam in the training beam subset determined in 105, and record the RSRP on each beam, and sort the transceiver beam pairs according to the RSRP from large to small, and retain RSRP's largest pre-P pair transmit and receive beam. A pair of P-pairs with the largest RSRP in the transmit and receive beams is selected as the current communication beam, and the remaining P-1 pairs are used as candidate beams. In this way, the set of allowed transmit beams is finally obtained as the preferred transmit and receive beam pairs at both ends of the transceiver.

在一种实施方式中，第一设备的监听波束集合中监听波束的数量与第一设备的训练波束结合中训练波束的数量可以相等，即K ₁＝K ₂，即第一设备监听信道的波束就是第一设备用于发送RTS的训练波束，同样的，第二设备的监听波束集合中监听波束的数量与第二设备的训练波束结合中训练波束的数量可以相等，即M ₁＝M _2， In an embodiment, the number of the monitoring beams in the monitoring beam set of the first device may be equal to the number of the training beams in the training beam combination of the first device, that is, K ₁ =K ₂ , that is, the beam of the first device listening channel The first device is used to send the training beam of the RTS. Similarly, the number of the monitoring beams in the monitoring beam set of the second device may be equal to the number of the training beams in the training beam combination of the second device, that is, M ₁ = M _2,

在另一种实施方式中，第一设备的监听波束集合中监听波束的数量可以小于第一设备的训练波束结合中训练波束的数量，即K ₁<K ₂，即第一设备监听信道的波束为粗波束，第一设备用于发送RTS的训练波束为细波束，同样的，第二设备的监听波束集合中监听波束的数量可以小于第二设备的训练波束结合中训练波束的数量，即M ₁<M ₂，例如，请参阅图9，图9是本申请实施例提供的一种粗波束监听，细波束训练的示意图，如图9所示，UE2、gNB2采用粗波束进行信道监听，细波束进行波束训练获得能够发送CTS或RTS的细波束。该实施方式相比上一均采用细波束监听，细波束训练的实施方式相比，虽然对网络容量有一定影响，比如粗波束监听获得的空闲信道数要小于细波束监听获得的空闲信道数，但可以减少信道监听过程中的波束扫描次数和时延开销。 In another implementation manner, the number of the monitoring beams in the monitoring beam set of the first device may be smaller than the number of training beams in the training beam combination of the first device, that is, K ₁ <K ₂ , that is, the beam of the first device listening channel For the coarse beam, the training beam used by the first device to send the RTS is a beamlet. Similarly, the number of the monitoring beams in the monitoring beam set of the second device may be smaller than the number of training beams in the training beam combination of the second device, that is, M. ₁ <M ₂ , for example, please refer to FIG. 9. FIG. 9 is a schematic diagram of a rough beam monitoring and a thin beam training according to an embodiment of the present application. As shown in FIG. 9 , UE2 and gNB2 use a thick beam for channel monitoring. Beams are beam trained to obtain a beamlet capable of transmitting CTS or RTS. Compared with the previous embodiment, the thin beam monitoring method has a certain influence on the network capacity, for example, the number of idle channels obtained by the coarse beam monitoring is smaller than the number of idle channels obtained by the thin beam monitoring. However, the number of beam scans and delay overhead during channel monitoring can be reduced.

再例如，表1为波束扫描复杂度的分析表，如表1所示，信令开销和时延大小与信道监听阶段、波束训练阶段的波束个数成正比。单独信道监听完毕，再进行波束训练所需的波束扫描次数为，第一设备执行K ₁次波束扫描，第二设备执行M ₁次波束扫描，分别获得信道空闲的监听波束，第一设备与第二设备先进行一次波束扫描配对，需要执行K ₂M ₂次波束扫描，再针对第一设备在K ₂个训练波束上发送RTS，第二设备在每个RTS的发送周期内，基于M ₂个训练波束进行波束扫描，即需要执行K ₂M ₂次波束扫描，同样的，第二设备在M ₂个训练波束上发送CTS，第一设备在每个CTS的发送周期，基于K ₂个训练波束进行波束扫描，需要执行K ₂M ₂次波束扫描，可见，采用先进行LBT监听，再进行波束训练的方式获得最佳波束对，需要经历M ₁+K ₁+3K ₂M ₂次波束扫描。本申请实施例一所需的波束扫描次数为，第一设备执行K ₁次波束扫描，第二设备执行M ₁次波束扫描，分别获得信道空闲的监听波束，其中，K ₁＝K ₂，M ₁＝M ₂，即监听波束集的波束个数等于波束训练波束集的波数个数，第一设备在K ₂个训练波束上发送RTS，第二设备在每个RTS的发送周期内，基于M ₂ 个训练波束进行波束扫描，即需要执行K ₂M ₂次波束扫描，同样的，第二设备在N(N<M ₂)个训练波束上发送CTS，第一设备在每个CTS的发送周期，基于K ₂个训练波束进行波束扫描，需要执行NK ₂次波束扫描，可见，采用联合LBT监听与波束训练的一体化信道接入机制获得最佳波束对，需要经历小于M ₁+K ₁+K ₂M ₂+NK ₂次波束扫描。本申请实施例二所需的波束扫描次数为，第一设备执行K ₁次波束扫描，第二设备执行M ₁次波束扫描，分别获得信道空闲的监听波束，其中，K ₁＝(1/2)*K ₂，M ₁＝(1/2)*M ₂或K ₁＝(1/4)*K ₂，M ₁＝(1/4)*M ₂，即监听波束集的波束个数是波束训练波束集的波束个数的2倍或4倍，第一设备在K ₂个训练波束上发送RTS，第二设备在每个RTS的发送周期内，基于M ₂个训练波束进行波束扫描，即需要执行K ₂M ₂次波束扫描，同样的，第二设备在N(N<M ₂)个训练波束上(即训练波束子集中的训练波束上)发送CTS，第一设备在每个CTS的发送周期，基于K ₂个训练波束进行波束扫描，需要执行NK ₂次波束扫描，可见，采用粗波束进行LBT监听，细波束进行波束训练获得最佳波束对，需要经历小于M ₁+K ₁+K ₂M ₂+NK ₂次波束扫描。本申请两个实施例采用LBT监听和波束训练联合实现的方式，能够大大的提高处理效率，并降低波束扫描配对的复杂度，同时还能解决暴露节点和隐藏节点的问题。 For another example, Table 1 is an analysis table of beam scanning complexity. As shown in Table 1, the signaling overhead and the delay size are proportional to the number of beams in the channel monitoring phase and the beam training phase. Separate channel sounding is completed, then the number of required beam scanning beam is trained, the first device performs beam scanning times K _1, a second sub-beam scanning device M _1, respectively beam monitor channel is idle, the first and the second device The second device performs beam scanning pairing first, and needs to perform K ₂ M ₂ beam scanning, and then sends RTS on K ₂ training beams for the first device, and the second device is based on M ₂ in each RTS transmission period. The training beam is used for beam scanning, that is, K ₂ M ₂ beam scanning needs to be performed. Similarly, the second device transmits CTS on M ₂ training beams, and the first device is based on K ₂ training beams in each CTS transmission period. To perform beam scanning, it is necessary to perform K ₂ M ₂ beam scanning. It can be seen that the best beam pair is obtained by performing LBT monitoring first and then performing beam training, and it is necessary to undergo M ₁ + K ₁ + 3K ₂ M ₂ beam scanning. A desired beam scan number of embodiments of the present application embodiment, a first device performs beam scanning times K _1, M ₁ times the second device performs beam scanning, respectively beam monitor channel is idle, wherein, K ₁ = K _2, M ₁ = M ₂ , that is, the number of beams of the monitoring beam set is equal to the number of wave numbers of the beam training beam set, the first device transmits the RTS on the K ₂ training beams, and the second device is based on the M in the transmission period of each RTS. _Two training beams are used for beam scanning, that is, K ₂ M ₂ beam scanning needs to be performed. Similarly, the second device transmits CTS on N (N < M ₂ ) training beams, and the first device transmits a cycle in each CTS. The beam scanning is performed based on K ₂ training beams, and NK ₂ beam scanning needs to be performed. It can be seen that the integrated beam access mechanism using the combined LBT monitoring and beam training obtains the optimal beam pair, and needs to experience less than M ₁ + K ₁ + K ₂ M ₂ + NK _2nd beam scan. Beam scanning times required for the present application according to the second embodiment in that the first device performs beam scanning times K _1, M ₁ times the second device performs beam scanning, respectively beam monitor channel is idle, wherein, K ₁ = (1/2 ) * K ₂ , M ₁ = (1/2) * M ₂ or K ₁ = (1/4) * K ₂ , M ₁ = (1/4) * M ₂ , that is, the number of beams of the monitor beam set is The number of beams of the beam training beam set is 2 or 4 times, the first device transmits the RTS on the K ₂ training beams, and the second device performs the beam scanning based on the M ₂ training beams in the transmission period of each RTS. That is, K ₂ M ₂ beam scanning needs to be performed. Similarly, the second device transmits CTS on N (N < M ₂ ) training beams (ie, training beams in the training beam subset), and the first device is in each CTS. The transmission period is based on K ₂ training beams for beam scanning. It is necessary to perform NK ₂ beam scanning. It can be seen that the LBT is monitored by the coarse beam, and the beamforming is performed by the beamlet to obtain the best beam pair, which needs to experience less than M ₁ +K ₁ +K ₂ M ₂ +NK _2nd beam scan. The two embodiments of the present application adopt a combination of LBT monitoring and beam training, which can greatly improve processing efficiency, reduce the complexity of beam scanning pairing, and solve the problem of exposed nodes and hidden nodes.
