收端辅助信息的传输方法、装置、终端及网络侧设备
相关申请的交叉引用
本申请要求于2021年9月28日提交的申请号为202111146548.3，发明名称为“收端辅助信息的传输方法、装置、终端及网络侧设备”的中国专利申请的优先权，其通过引用方式全部并入本申请。
技术领域
本申请属于通信技术领域，具体涉及一种收端辅助信息的传输方法、装置、终端及网络侧设备。
背景技术
在未来通信系统中，共享频谱例如非授权频段(unlicensed band)可以作为授权频段(licensed band)的补充帮助运营商对服务进行扩容。为了与NR部署保持一致并尽可能的最大化基于NR的非授权接入，非授权频段可以工作在5GHz，37GHz和60GHz频段。由于非授权频段由多种无线接入技术(Radio Access Technology，RAT)共用，例如无线通信技术(Wi-Fi)，雷达，长期演进授权辅助接入(Long Term Evolution License Assisted Access，LTE-LAA)等，因此在某些国家或者区域，非授权频段在使用时必须符合相应规则以保证所有设备可以公平的使用该资源，例如先听后说(Listen Before Talk，LBT)，最大信道占用时间(Maximum Channel Occupancy Time，MCOT)等规则。当传输节点需要发送信息时，需要先做LBT时，对周围的节点进行功率检测(Energy Detection，ED)，当检测到的功率低于一个门限时，认为信道为空(idle)，传输节点可以进行发送。反之，则认为信道为忙，传输节点不能进行发送。传输节点可以是基站，用户设备(User Equipment，UE)，Wi-Fi接入点(Access Point，AP)等等。传输节点开始传输后，信道占用时间(Channel Occupancy Time，COT)不能超过MCOT。
如图1所示，gNB1在发送数据前做LBT，侦听到信道为空，因此gNB1向UE1发送数据，UE1接收数据。此时UE2有数据需要发送，做LBT，因为gNB1离得比较远，因此UE2侦听到信道为空，开始发送数据。但是由于gNB2和gNB1之间是视距(Line OfSight，LOS)信道，gNB2可以接收到gNB1发送的信息，此时gNB2在接收UE2的数据时会受到干扰。gNB1是gNB2的隐藏节点。为了进一步减少收端隐藏节点的干扰，引入了传输请求/传输确认(Request-To-Send/Clear-To-Send， RTS/CTS)的握手机制。源节点在数据传输前发送RTS，RTS中携带有网络分配矢量(Network Allocation Vector，NAV)值和目的节点的地址，表示该节点要占用信道多长时间。所有收到该RTS的节点在NAV时间内不会尝试进行数据传输。其中目的节点在接收到RTS后，回复一个CTS，CTS中携带有NAV值和源节点的地址。除了源节点和目的节点之外所有接收到CTS的节点在NAV时间内不会尝试进行传输，这样就避免了目的节点周围的隐藏节点问题。
接收端反馈的信息，例如上述CTS，可以称之为收端辅助信息(Receiver Assistance Information)。在3GPP通信标准中，可以采用类似的机制辅助基站端进行下行传输。基站触发终端发送收端辅助信息，终端收到触发信息后，在侦听到信道为空的情况下向基站发送收端辅助信息，当基站接收到终端侧发送的收端辅助信息后方可向该终端进行下行传输。该收端辅助信息意味着终端侧不存在干扰的隐藏节点。具体如何根据基站端的指示发送收端辅助信息，是本领域技术人员亟需解决的技术问题。

下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的收端辅助信息的传输方法进行详细地说明。
图3是本申请实施例提供的收端辅助信息的传输方法的流程示意图之一。如图3所示，本实施例提供的收端辅助信息的传输方法，包括：
步骤101、终端接收网络侧设备发送的第一信息；第一信息包括以下至少一项：LBT类型、探测参考信号SRS的触发信息、物理上行控制信道PUCCH的触发信息、物理上行链路共享信道PUSCH的调度信息；
具体地，网络侧设备在进行下行数据传输之前向终端发送第一信息，终端接收网络侧设备发送的第一信息，第一信息用于触发终端发送收端辅助信息，第一信息可以包括以下至少一项：LBT类型、探测参考信号(Sounding Reference Signal，SRS)的触发信息、物理上行控制信道(Physical Uplink Control Channel，PUCCH)的触发信息、物理上行链路共享信道(Physical Uplink Shared Channel，PUSCH)的调度信息，其中，LBT类型可以通过协议预定义或网络侧设备配置或通过信令指示，例如通过下行控制信息(Downlink Control Information，DCI)信令指示。
可选地，SRS、PUCCH、PUSCH的触发信息可以通过信令指示，例如DCI信令。
可选地，当第一信息不包含LBT类型时，LBT类型可以通过无线资源控制(Radio Resource Control，RRC)信令发送或者由协议约定。
可选地，LBT的类型(Category)可以分为Category 1，Category 2，Category3和Category4。Category1 LBT是发送节点不做LBT，即no LBT或者立即传输(immediate transmission)。Category 2 LBT是one-shot LBT，即节点在传输前做一次LBT，信道为空则进行传输，信道为忙则不传输。Category 3和Category 4 LBT是基于回退(back-off)的信道侦听机制，当传输节点侦听到信道为忙时，进行回退，继续做侦听，直到侦听到信道为空。其中，Category 3 LBT的竞争窗大小(contention Window size)是固定的；Category 4 LBT的竞争窗(contention Window size)是可变的。此外，Category 4 LBT也可以叫做Type1信道接入机制，Category 2 LBT也可以叫做Type 2信道接入机制。
步骤102、在终端执行LBT成功后，终端根据第一信息向网络侧设备发送收端辅助信息。
其中，执行LBT成功指的是侦听到信道空闲。
可选地，所述收端辅助信息包括以下至少一项：SRS、PUCCH或者PUSCH。
具体地，终端在发送收端辅助信息之前，需要执行LBT，在LBT成功(即侦听到信道空闲)后，发送收端辅助信息，其中，收端辅助信息具体的内容需要根据第一信息的指示确定。
可选地，值得指出的是，终端根据第一信息向网络侧设备发送收端辅助信息的过程中，终端不进行接收。
可选地，终端可以通过SRS、PUCCH或者PUSCH显式地或者隐式地向网络侧设备指示终端侧的信道状况或者LBT结果，隐藏节点等信息。例如，当网络侧设备接收到收端辅助信息后，则意味着终端LBT成功，或者终端周围没有隐藏节点，或者说终端侧信道为空。
本实施例的方法，终端接收网络侧设备发送的第一信息；第一信息用于触发终端发送收端辅助信息，第一信息包括以下至少一项：LBT类型、探测参考信号SRS的触发信息、物理上行控制信道PUCCH的触发信息、物理上行链路共享信道
PUSCH的调度信息；进一步地，在终端执行先听后说LBT成功后，终端根据网络侧设备第一信息的指示向网络侧设备发送收端辅助信息，网络侧设备在接收到收端辅助信息后，可以确定终端周围没有隐藏节点，这时向终端发送下行信息，将不会受到隐藏节点的影响。
在一实施例中，终端根据第一信息发送收端辅助信息之后，还包括：
终端接收网络侧发送的下行信道或信号。
具体地，若网络侧设备收到SRS、PUCCH或者特定时域长度的PUSCH，则网络侧设备向该终端发送组公共(Group Common，GC)-物理下行链路控制信道(Physical Downlink Control Channel，PDCCH)，PDSCH，广播信号等下行信道/信号。
上述实施方式中，网络侧设备在接收到收端辅助信息后，则可确定终端周围没有隐藏节点，可以向终端发送下行信道或信号，这时向终端发送下行信息，将不会受到隐藏节点的影响。
在一实施例中，该方法还包括：
在收端辅助信息未成功发送的情况下，终端不进行PDSCH检测。
具体地，在收端辅助信息未成功发送的情况下，终端不期望接收物理下行链路共享信道(Physical Downlink Shared Channel，PDSCH)，不进行PDSCH检测。
上述实施方式中，在收端辅助信息未成功发送的情况下，终端不进行PDSCH检测，可以减少终端的功耗。
在一实施例中，在收端辅助信息包括SRS的情况下，SRS的触发信息通过下行控制信息DCI中探测参考信号SRS请求域、时域资源分配TDRA、频域资源分配FDRA域、上行共享信道UL-SCH指示域、第一指示域中至少一项指示；
在收端辅助信息包括PUCCH的情况下，PUCCH的触发信息通过下行控制信息DCI中探测参考信号SRS请求域、时域资源分配TDRA、频域资源分配FDRA域、第二指示域中至少一项指示；
在收端辅助信息包括所述PUSCH的情况下，PUSCH的调度信息包括以下至少 一项：LBT类型、PUSCH的时域长度；
其中，第一指示域或第二指示域用于指示是否检测DCI调度的物理下行链路共享信道PDSCH。
具体地，对于第一指示域和第二指示域，DCI中可仅包含第一指示域，或仅包含第二指示域，或同时包含第一指示域和第二指示域。第一指示域和第二指示域可以是DCI中相同或不同的指示域，可选地，若第一指示域和第二指示域为相同的域，可以通过该域中不同的字段指示，可选地，DCI为下行分配DCI(DL assignment DCI)。
在收端辅助信息包括SRS的情况下，SRS的触发信息通过下行控制信息DCI中探测参考信号SRS请求域、时域资源分配(Time Domain Resource Assignment，
TDRA)、频域资源分配(Frequency Domain Resource Assignment，TDRA)域、上行共享信道(Uplink Shared Channel，UL-SCH)指示域、第一指示域中至少一项指示；
在收端辅助信息包括PUCCH的情况下，PUCCH的触发信息通过下行控制信息DCI中探测参考信号SRS请求域、时域资源分配TDRA、频域资源分配FDRA域、第二指示域中至少一项指示。
可选地，第一指示域和第二指示域可以是DCI中新增的域，或者原有域中的部分字段。
在收端辅助信息包括PUSCH的情况下，PUSCH的调度信息包括以下至少一项：LBT类型、PUSCH的时域长度。
可选地，PUSCH的调度信息可以通过上行分配DCI携带。
当网络侧设备指示终端采用特定类型LBT发送SRS、PUCCH或者特定时域长度的PUSCH，若网络侧设备未检测到对应的信号或者信道，网络侧设备可以继续指示终端采用特定类型LBT发送SRS、PUCCH或者特定时域长度的PUSCH，直到收到对应的信号或者信道。在没有收到SRS、PUCCH或者特定时域长度的PUSCH之前，网络侧设备不会向该终端发送PDSCH，终端不用检测PDSCH。
例如当网络侧设备指示终端采用类型2LBT发送SRS、PUCCH或者特定时域长度的PUSCH，当终端侦听到信道为忙时则不发送SRS、PUCCH或者特定时域长度的PUSCH。若网络侧设备未检测到对应的信号或者信道，网络侧设备可以继续指示终端采用类型2LBT发送SRS、PUCCH或者特定时域长度的PUSCH，直到收到对应的信号或者信道。
可选地，特定类型LBT包括以下至少一项：类型2LBT、类型3LBT、类型4LBT，其中，类型3和类型4LBT的竞争窗大小为目标值；可选地，目标值的取值范围为大于或等于0，且小于或等于3的整数。
可选地，特定时域长度为1个符号长度或2个符号长度。
上述实施方式中，终端根据网络侧设备的不同指示，发送不同的收端辅助信息，网络侧设备在接收到收端辅助信息后，则可确定终端周围没有隐藏节点，这时向终端发送下行信息，将不会受到隐藏节点的影响。
在一实施例中，在收端辅助信息包括SRS的情况下，第一信息的指示方式存在以下几种情况：
一种情况：
上行分配DCI中SRS请求域的取值为第一预设值，且上行共享信道UL-SCH指示域的取值为第二预设值。
可选地，网络侧设备通过DCI格式0_1或者DCI格式0_2触发终端发送SRS。
具体地，SRS请求域(request域)取值为第一预设值。UL-SCH指示(indicator域)取值为第二预设值。终端在收到第一信息的指示后，若LBT成功，则仅发送SRS，不发送PUSCH。若终端没有成功发送SRS，则终端不期望收到PDSCH，不检测PDSCH。
可选地，第一预设值为非全零，第二预设值为零。
另一种情况：
下行分配DCI中SRS请求域的取值为第一预设值，时域资源分配TDRA域的取值为无效值，且频域资源分配FDRA域的取值为有效值。
可选地，第一预设值为非全零。
具体地，网络侧设备通过RRC在TDRA表(table)中配置一个无效值(invalid entry)。该无效值表示该调度无效，无效值指示的时域资源长度可以为零或者起始和长度指示值(Start And Length Indicator Value，SLIV)值为无效值。
可选地，网络侧设备通过DCI格式1_1或者DCI格式1_2触发终端发送SRS。
其中，SRS请求域取值为非全零，TDRA域指示无效值，FDRA域指示有效值。当终端收到该DCI指示时，不检测该DCI调度的PDSCH，忽略无效的PDSCH调度。
当LBT成功时，终端仅发送SRS，不发送PUCCH。若终端没有成功发送SRS，则UE不期望收到PDSCH，不进行PDSCH检测。
可选地，终端忽略PUCCH资源指示(PUCCH Resource Indicator，PRI)和PDSCH到HARQ的反馈定时(PDSCH-to-HARQ_feedback timing)，该PDSCH-to-HARQ_feedback timing字段就是用来指示PDSCH完成数据发送后，需要在多长的时间内发送HARQ-ACK信息。
另一种情况：
下行分配DCI中第一指示域的取值为第三预设值，SRS请求域的取值为第一预 设值，且FDRA域的取值为有效值。
可选地，第一预设值为非全零。
可选地，可以通过在DCI格式1_1或者DCI格式1_2中增加第一指示域，或复用原有域，将DCI中已有的某个域作为该第一指示域，第一指示域的长度为至少一个比特；或者还可以将原有域增加至少一个比特，用于指示是否检测所述DCI调度的PDSCH。
具体地，当该第一指示域为1比特，且取值为第三预设值，例如为1，SRS请求域的取值为非全零，且FDRA域指示有效值，则终端不检测该DCI调度的PDSCH，不进行PUCCH传输，即忽略PDSCH和PUCCH的调度。终端根据DCI指示，当LBT成功时，仅发送SRS。若终端没有成功发送SRS，则终端不期望收到PDSCH。
可选地，终端忽略PRI和PDSCH-to-HARQ_feedback timing，该PDSCH-to-HARQ_feedback timing字段就是用来指示PDSCH完成数据发送后，需要在多长的时间内发送HARQ-ACK信息。
上述实施方式中，终端根据网络侧设备的指示，发送SRS作为收端辅助信息，网络侧设备在接收到收端辅助信息后，则可确定终端周围没有隐藏节点，这时向终端发送下行信息，将不会受到隐藏节点的影响。
可选地，该方法还包括：
第一指示域的取值为第四预设值，SRS请求域的取值为第一预设值，且FDRA域的取值为有效值，终端接收网络侧设备调度的物理下行链路共享信道PDSCH。
可选地，第一预设值为非全零。
具体地，当该第一指示域为1比特，且取值为第四预设值，例如为0，SRS请求域的取值为非全零，且FDRA域指示有效值，则终端根据调度接收PDSCH并在LBT成功后发送SRS和PUCCH。
上述实施方式中，终端根据网络侧设备的指示，接收网络侧设备正常调度的PDSCH，并发送SRS和PUCCH。
在一实施例中，在收端辅助信息包括PUCCH的情况下，第一信息的指示方式存在以下几种情况：
一种情况：
下行分配DCI中TDRA域的取值为无效值，且FDRA域的取值为有效值。
具体地，网络侧设备通过RRC在TDRA表中配置一个无效值。该无效值表示该调度无效，无效值指示的时域资源长度可以为零或者SLIV为无效值。
可选地，网络侧设备通过DCI格式1_1或者DCI格式1_2触发终端发送PUCCH。
可选地，下行分配DCI中SRS请求域的取值，与收端辅助信息包括SRS的情况 下SRS请求域的取值不同，此时下行分配DCI中SRS请求域的取值可以为全零。
例如，SRS请求域取值为全零，TDRA域指示invalid entry，FDRA指示有效值。当终端收到该DCI指示时，忽略无效的PDSCH调度，当LBT成功时，UE发送PUCCH。若UE没有成功发送PUCCH，则UE不期望收到PDSCH，即不检测PDSCH。
另一种情况：
下行分配DCI中第二指示域的取值为第三预设值，且FDRA域的取值为有效值。
可选地，可以通过在DCI格式1_1或者DCI格式1_2中增加第二指示域，或复用原有域，将DCI中已有的某个域作为该第二指示域，第二指示域的长度为至少一个比特；或者还可以将原有域增加至少一个比特，用于指示是否检测所述DCI调度的PDSCH。
可选地，SRS请求域的取值为全零。
具体地，当该第二指示域为1比特，且取值为第三预设值，例如为1，SRS请求域的取值为全零，且FDRA指示有效值，则终端忽略PDSCH调度。UE根据DCI指示，当LBT成功时发送PUCCH。若终端没有成功发送PUCCH，则终端不期望收到PDSCH。
上述实施方式中，终端根据网络侧设备的指示，发送PUCCH作为收端辅助信息，网络侧设备在接收到收端辅助信息后，则可确定终端周围没有隐藏节点，这时向终端发送下行信息，将不会受到隐藏节点的影响。
可选地，该方法还包括：
第二指示域的取值为第四预设值，且FDRA域的取值为有效值，终端接收网络侧设备调度的物理下行链路共享信道PDSCH。
可选地，SRS请求域的取值为全零。
具体地，第二指示域为1比特，且取值为第四预设值，例如，第四预设值为0，SRS请求域的取值为全零，且FDRA域指示有效值，则终端根据调度接收PDSCH并在LBT成功后发送PUCCH。
上述实施方式中，终端根据网络侧设备的指示，接收网络侧设备正常调度的PDSCH并发送PUCCH。
在一实施例中，DCI中指示的LBT类型为预设类型，且PUSCH的时域长度为预设长度，收端辅助信息为PUSCH。
具体地，若终端收到DCI指示预设类型LBT和预设长度的PUSCH，则终端根据指示执行LBT，若LBT成功，则发送PUSCH。若终端没有数据可传输，则终端生成填充(padding)缓存区状态报告(Buffer Status Report，BSR)进行发送。如果终端没有成功发送特定长度的PUSCH，则UE不期望收到PDSCH。
可选地，预设长度为1个符号长度或2个符号长度。
可选地，预设类型为LBT类型2、LBT类型3或LBT类型4，其中，所述LBT类型3和LBT类型4的竞争窗大小为目标值；目标值的取值范围为大于或等于0，且小于或等于3的整数。
上述实施方式中，终端根据网络侧设备的指示，发送PUSCH作为收端辅助信息，网络侧设备在接收到收端辅助信息后，则可确定终端周围没有隐藏节点，这时向终端发送下行信息，将不会受到隐藏节点的影响。
在一实施例中，该方法还包括：
终端接收网络侧设备发送的第二信息，第二信息为网络侧设备在未接收到收端辅助信息后发送的；第二信息用于触发所述终端发送收端辅助信息，收端辅助信息为终端执行LBT成功后发送的。第二信息可以是网络侧设备没有收到收端辅助信息时，继续发送的第一信息。
可选地，第二信息包括以下至少一项：LBT类型、探测参考信号SRS的触发信息、物理上行控制信道PUCCH的触发信息、物理上行链路共享信道PUSCH的调度信息。
具体地，网络侧设备在预设时长内未接收到收端辅助信息，向终端发送第二信息，第二信息用于触发终端发送收端辅助信息，终端执行LBT成功后发送收端辅助信息。
其中，网络侧设备未接收到收端辅助信息，可能是终端没有发送，或终端发送之后由于信号干扰等原因网络侧设备没有接收到。
上述实施方式中，网络侧设备在未接收到收端辅助信息后发送第二信息，用于触发终端发送收端辅助信息，网络侧设备在接收到收端辅助信息后，则可确定终端周围没有隐藏节点，这时向终端发送下行信息，将不会受到隐藏节点的影响。

步骤100b、终端执行先听后说LBT；

步骤103a、网络侧设备接收到收端辅助信息后向终端发送下行信道或信号；
