随机接入过程的竞争解决方法、终端及网络侧设备

本申请要求于2021年07月23日提交的申请号为202110839574.8，发明名称为“随机接入过程的竞争解决方法、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，具体涉及一种随机接入过程的竞争解决方法、终端及网络侧设备。
背景技术
在相关技术中，包含竞争的随机接入流程和非竞争随机接入的流程。其中，竞争的随机接入过程，也称为4步随机接入信道(Random Access Channel，RACH)，终端首先向网络发送消息1Msg1，包含导频序列preamble；网络检测到preamble后，将发送消息2Msg2，包含该preamble对应的随机接入响应(Random Access Response，RAR)消息；终端接收到Msg2后，根据RAR的指示，发送消息3Msg3；网络收到Msg3后，将发送消息4Msg4，包含竞争解决ID(Contention Resolution Identity)；终端收到msg4，即完成4步随机接入。网络在RAR中包含上行(Uplink，UL)授权grant信息用于指示Msg3物理上行共享信道(Physical Uplink Shared Channel，PUSCH)调度信息，并且包含随机接入信道导频序列标识(RACH preamble ID，RAPID)，临时小区无线网络临时标识(Temporary Cell Radio Network Temporary Identifier，TC-RNTI)，定时提前量(Timing Advance,TA)等信息。如果网络没有接收到Msg3 PUSCH，可以在TC-RNTI加扰的物理下行控制信道(Physical Downlink Control Channel，PDCCH)中调度Msg3  PUSCH的重传。
对于竞争的随机接入过程，不同的终端随机选取preamble进行传输，这样不同的终端可能在相同的资源上选取相同的preamble发送，触发竞争随机接入过程。这种情况可以理解为终端的preamble冲突。这种情况下，不同的终端会收到相同的RAR，则此时不同的终端会根据该RAR UL grant中的调度信息，进行Msg3 PUSCH的传输。由于相关技术不支持Msg3 PUSCH的重复传输，网络在一个Msg3 PUSCH调度资源上只能解出一个终端发送的PUSCH，所以，网络会在Msg4物理下行共享信道(Physical Downlink Shared Channel,PDSCH)中包含竞争解决ID和终端在Msg3 PUSCH中发送的公共控制信道(Common Control Channel,CCCH)业务数据单元(Service Data Unit，SDU)匹配，则终端认为竞争解决成功，并将TC-RNTI作为终端的小区无线网络临时标识(Cell Radio Network Temporary Identity，C-RNTI)。如果不匹配，则认为竞争解决不成功。如果竞争解决不成功，则终端重新选择RACH发送资源，进行物理随机接入信道(Physical Random Access Channel,PRACH)发送，进行下一次随机接入尝试。
如果终端支持Msg3重复传输，和/或网络指示了Msg3 PUSCH重复传输，终端会在多个时机occasion上进行PUSCH重复传输，则网络可能解出多个终端发送的Msg3 PUSCH，会导致接入时延较大。因此，如何对相关随机接入过程进行优化，以减少终端接入时延是需要解决的。

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随机接入过程的竞争解决方法进行详细地说明。
图2为本申请实施例提供的随机接入过程的竞争解决方法的流程示意图之一，如图2所示，该方法包括以下步骤：
步骤200、终端根据消息4Msg4的接收，确定收发行为；
其中，所述收发行为包括以下至少一项：
进行消息3Msg3重复传输；
不进行Msg3重复传输；
确定所述终端的小区无线网络临时标识C-RNTI或临时小区无线网络临时标识TC-RNTI。
需要说明的是，本申请实施例中，Msg4为传输竞争解决消息的PDSCH和/或PDCCH，此处，所述PDCCH为TC-RNTI进行循环冗余校验(Cyclic redundancy check，CRC)加扰的用于调度PDSCH的PDCCH。
在一种增强的随机接入流程中，网络可以调度Msg3 PUSCH的N次 (N>＝1)重复传输，网络可能在终端完成N次重复传输之前，解调出第一UE发送的Msg3。那么网络可以向第一UE发送Msg4，第一UE解调出Msg4之后则竞争解决成功。
然而由于该随机接入过程是4步的随机接入过程，多个UE可能同时发送相同的preamble，则多个UE可以接收到RAR后，在相同的资源上进行Msg3的重复传输。而网络在不同的时刻可以进行多次Msg3重复传输的解调，在不同的时刻收到多个UE发送的Msg3，会导致接入时延较大。接入时延较大的原因如下：首先，Msg3重复传输虽然提升了传输性能，但是由于传输了多次，本身就增加了接入时延；进一步地，以两个UE同时发送了相同的preamble为例，在接收到Msg4后，第一UE竞争解决成功，第二UE竞争解决不成功，对于第二UE，按照现有随机接入流程，第二UE会重新开始从Msg1开始新的随机接入流程，导致接入时延较大；另外，由于相关技术不支持停止剩余的Msg3 PUSCH重复传输，第二UE已经竞争解决失败了，在重复传输资源不可用等情况下，若还不能让第二UE停止重复传输，开始新的随机接入流程，也会增加接入时延。因此，本申请实施例提供了随机接入过程的竞争解决方法，对相关随机接入流程进行了优化。
可选地，终端根据Msg4的接收确定竞争解决是否成功，进而确定收发行为。其中，收发行为包括是否进行Msg3重复传输，和/或确定该终端的C-RNTI或TC-RNTI。
需要说明的是，在本申请中，Msg3重复传输包括：RAR UL grant调度的PUSCH重复传输Repeat transmission，或者TC-RNTI加扰的PDCCH调度的重传retransmission。
例如，第一UE在竞争解决成功后停止Msg3重复传输，第二UE竞争解决不成功，可以继续在N次重复传输中剩余的未完成的M次传输资源上，继续进行Msg3 PUSCH的重复传输。
可选地，对于竞争解决不成功的终端，可以不重新开始进行随机接入的尝试，而是基于当前随机接入的进度(即基于已有的RAR提供的信息，包括 调度信息，TA，TC-RNTI等)继续接入直至接入成功，避免了重新尝试随机接入带来的接入时延。
可选地，对于竞争解决不成功的终端，也可以停止剩余未完成的Msg3重复传输，例如，在网络指示Msg3重复传输资源不可用，或者网络指示终端停止剩余未完成的Msg3重复传输的情况下，使得终端可以更快重新开始新的随机接入尝试。
图3为本申请实施例提供的停止Msg3重复传输的示意图。
在相关技术中，如果第一UE竞争解决成功，则将在RAR中收到的TC-RNTI，作为第一UE的C-RNTI。如果第二UE需要继续进行Msg3的重复传输，及进行后续的Msg4的接收，则还是需要基于该TC-RNTI进行监听，则该TC-RNTI不能作为第一UE的C-RNTI。为了对上述流程进行优化，在本申请中，终端的收发行为还包括：确定所述终端的小区无线网络临时标识C-RNTI或临时小区无线网络临时标识TC-RNTI。
可选地，竞争解决成功是指终端检测到Msg4 PDSCH中包含的竞争解决标识ID和所述终端在Msg3 PUSCH中发送的公共控制信道CCCH业务数据单元SDU匹配。
可选地，竞争解决不成功是指终端检测到Msg4 PDSCH中包含的竞争解决ID和所述终端在Msg3 PUSCH中发送的CCCH SDU不匹配。
在本申请实施例中，终端根据消息4Msg4的接收，确定是否进行Msg3重复传输和/或确定该终端的C-RNTI或TC-RNTI，可以优化随机接入流程，减少接入时延，提升接入效率。
可选地，终端的收发行为可以是预定义的。
在终端接收到Msg4并且竞争解决成功的情况下，所述收发行为包括以下至少一项：
不继续进行未完成的Msg3重复传输；
清除Msg3对应的混合自动重传请求(Hybrid automatic retransmission request，HARQ)缓存buffer；
忽略Msg3物理上行共享信道PUSCH的上行授权信息UL grant；
在终端接收到Msg4并且竞争解决不成功的情况下，所述收发行为包括：
继续进行未完成的Msg3重复传输。
可选地，在终端完成N次Msg3重复传输之前，接收到Msg4，根据Msg4中携带的信息确定竞争解决成功的情况下，终端执行以下操作至少之一:不继续进行未完成的Msg3重复传输，清除Msg3对应的HARQ butffer，忽略Msg3 PUSCH的UL grant。
可以理解的是，清除了Msg3对应的HARQ butffer，则终端无法继续进行Msg3重复传输；忽略Msg3 PUSCH的UL grant，则终端没有Msg3 PUSCH传输资源，也无法继续进行Msg3重复传输。
可选地，在终端完成N次Msg3重复传输之前，接收到Msg4，根据Msg4中携带的信息确定竞争解决不成功的情况下，终端继续进行未完成的Msg3重复传输。即终端根据Msg4的接收确定竞争解决不成功，则继续进行未完成的Msg3重复传输，从而避免重新尝试随机接入带来的接入时延。
可选地，终端根据网络指示确定收发行为。
所述终端根据消息4Msg4的接收，确定收发行为，包括：
在终端接收到Msg4并且竞争解决不成功的情况下，根据第一指示信息，确定收发行为；
其中，所述第一指示信息用于指示以下至少一项：
终止Msg3重复传输；
不终止Msg3重复传输；
Msg3 PUSCH传输资源可用；
Msg3 PUSCH传输资源不可用；
清除Msg3对应的HARQ buffer；
不清除Msg3对应的HARQ buffer；
C-RNTI或TC-RNTI。
可选地，在终端接收到Msg4并且竞争解决不成功的情况下，终端根据 网络的指示确定收发行为。
网络可以通过第一指示信息指示终端终止Msg3重复传输，这样终端可以尽快重新进行新的随机接入尝试，提升接入效率。
网络也可以通过第一指示信息指示终端继续进行未完成的Msg3重复传输，从而使得终端可以基于当前的随机接入进度，继续接入成功，避免重新尝试随机接入带来的接入时延。
其中，Msg3 PUSCH传输资源为终端在收到Msg4之后的Msg3 PUSCH传输资源。
终止Msg3重复传输可以理解为停止未完成的Msg3重复传输；不终止Msg3重复传输可以理解为继续进行未完成的Msg3重复传输。
可选地，第一指示信息可以用于指示终端是否终止Msg3重复传输，Msg3 PUSCH传输资源是否可用，是否清除Msg3对应的HARQ buffer，和/或，终端的C-RNTI或TC-RNTI。
可选地，在第一指示信息指示终止Msg3重复传输、Msg3 PUSCH传输资源不可用和/或清除Msg3对应的HARQ buffer的情况下，终端不进行Msg3重复传输。
可选地，第一指示信息指示不终止Msg3重复传输、Msg3 PUSCH传输资源可用和/或不清除Msg3对应的HARQ buffer时，终端进行Msg3重复传输。
在本申请实施例中，终端根据消息4Msg4的接收，确定竞争解决是否成功，在竞争解决未成功的情况下，根据第一指示信息确定收发行为，可以优化随机接入流程，减少接入时延，提升接入效率。
可选地，所述第一指示信息通过Msg4或者调度Msg4的PDCCH传输。即所述第一指示信息被携带在Msg4 PDSCH中，或者，被携带在调度Msg4的PDCCH中。
可选地，在所述第一指示信息通过调度Msg4的PDCCH传输的情况下，终端物理层向终端媒体访问控制(Media Access Control，MAC)层传递所述 第一指示信息。然后，终端的MAC层执行所述收发行为。
例如，第一指示信息指示终止Msg3 PUSCH重复传输，该第一指示信息通过调度Msg4的TC-RNTI加扰的PDCCH传输，则UE的MAC层行为，包括以下至少其中之一：清除HARQ buffer，忽略Msg3传输的UL grant，或者说终端执行了这些行为，则不会再进行Msg3 PUSCH的重复传输。
可选地，在所述第一指示信息通过Msg4的MAC协议数据单元(Protocol Data Unit，PDU)或MAC子协议数据单元sub PDU传输的情况下，终端MAC层向终端物理层传递所述第一指示信息。然后，终端物理层执行所述收发行为。
例如，第一指示信息指示终止Msg3 PUSCH重复传输，该第一指示信息通过Msg4的MAC PDU或MAC sub PDU传输，终端MAC层向终端物理层传递该第一指示信息，使得终端物理层停止Msg3 PUSCH重复传输。
可选地，在所述第一指示信息指示所述终止Msg3重复传输或Msg3 PUSCH传输资源不可用的情况下，所述收发行为，包括以下至少一项：
停止Msg3重复传输；
清除Msg3对应的HARQ buffer；
忽略Msg3 PUSCH的UL grant。
可选地，在所述第一指示信息指示所述不终止Msg3重复传输或Msg3 PUSCH传输资源可用的情况下，所述终端的收发行为，包括：
终端根据Msg3的调度信息继续进行Msg3重复传输。
其中，Msg3的调度信息通过RAR UL grant，或者，TC-RNTI加扰的PDCCH传输。
可选地，在上述实施例的基础上，所述方法还包括：
终端在接收到所述Msg4第一预设时间后，执行所述收发行为。
可以理解的是，终端根据Msg4的接收，确定收发行为，第一预设时间后，执行该收发行为。例如，终端在接收到Msg4第一预设时间T后，进行或不进行未完成的Msg3重复传输。
其中，第一预设时间T可以是以毫秒数，符号数或slot数为单位。
可选地，终端在接收到所述第一指示信息第一预设时间后，执行所述收发行为。
相关技术中，如果第一终端竞争解决成功，则将在RAR中收到的TC-RNTI，作为第一终端的C-RNTI；而第二终端需要继续进行Msg3的重复传输，及进行后续的Msg4的接收，则还是需要基于该TC-RNTI进行监听，则该TC-RNTI不能作为第一终端的C-RNTI。一种优化方式是，对于竞争解决成功的UE，在Msg4中包含C-RNTI，竞争解决成功的第一终端使用该新的C-RNTI，丢弃在RAR中接收到的TC-RNTI。对于竞争解决未成功的第二终端，仍然使用TC-RNTI进行Msg3的发送，和后续Msg4的接收。
可选地，终端根据Msg4中是否包含C-RNTI，和/或，根据第一指示信息确定C-RNTI/TC-RNTI。
可选地，在终端接收到Msg4并且竞争解决成功的情况下，所述确定所述终端的小区无线网络临时标识C-RNTI或临时小区无线网络临时标识TC-RNTI，包括：
在所述Msg4中包含C-RNTI的情况下，丢弃在随机接入响应RAR中接收到的TC-RNTI，并使用Msg4中的C-RNTI作为所述终端的C-RNTI；
或者，在所述Msg4中不包含C-RNTI的情况下，使用在RAR中接收到的TC-RNTI作为所述终端的C-RNTI。
可以理解的是，Msg4中包含的C-RNTI是给竞争解决成功的终端的。在终端接收到Msg4并且竞争解决成功的情况下，若所述Msg4中包含C-RNTI，则使用Msg4中的C-RNTI作为该竞争解决成功的终端的C-RNTI，那么其他竞争解决不成功的终端可以继续使用TC-RNTI监听PDCCH，并接收调度的Msg4。如此，不管是已经竞争解决成功的终端，还是竞争解决未成功的终端，都能接收到Msg4，并竞争解决成功。
可选地，在终端接收到Msg4并且竞争解决不成功的情况下，所述方法还包括以下至少之一：
继续使用在RAR中接收到的TC-RNTI进行PDCCH的监听；
继续运行或者重启随机接入竞争解决定时器ra-Contention Resolution timer。
可选地，在终端接收到Msg4并且竞争解决不成功的情况下，确定继续进行未完成的Msg3重复传输，则继续使用在RAR中接收到的TC-RNTI进行PDCCH的监听，和/或，继续运行或者重启随机接入竞争解决定时器ra-Contention Resolution timer。
可选地，在满足预设条件的情况下，继续使用在RAR中接收到的TC-RNTI进行PDCCH的监听，和/或，继续运行或者重启随机接入竞争解决定时器ra-Contention Resolution timer；
其中，所述预设条件包括以下至少一项：
所述Msg4中包含C-RNTI；
第一指示信息指示不终止Msg3重复传输；
第一指示信息指示Msg3 PUSCH传输资源可用；
第一指示信息指示不清除Msg3对应的HARQ buffer。
可选地，若终端接收到的Msg4的MAC PDU或MAC Sub PDU中包含C-RNTI，该C-RNTI为网络侧设备给其他竞争解决成功的终端的C-RNTI，则终端确定在RAR中接收到的TC-RNTI还可以继续使用。
可选地，若终端根据第一指示信息确定继续进行未完成的Msg3重复传输，即第一指示信息指示以下至少一项：不终止Msg3重复传输，Msg3 PUSCH传输资源可用，不清除Msg3对应的HARQ buffer，则终端继续使用在RAR中接收到的TC-RNTI。
可选地，在终端接收到Msg4并且竞争解决不成功的情况下，若不满足上述预设条件，则终端丢弃所述TC-RNTI。
图4为本申请实施例提供的一种MAC Sub PDU的格式示意图，如图4所示，Msg4中除了包括竞争解决ID外，还进一步包括了终端的C-RNTI。
可选地，Msg4的MAC Sub PDU中可以包括定时提前量TA或者传输功 率控制(Transmission Power Control，TPC)命令，使得终端可以更新这些传输参数(如上行传输的定时提前量，发送功率等)，获得更好的上行传输性能。
可选地，在所述第一指示信息通过调度Msg4的PDCCH传输的情况下，所述第一指示信息包含在第一信息域中；
其中，所述第一信息域包括以下至少一项：下行分配索引(Downlink assignment index，DAI)，频域资源分配(Frequency Domain Resource Allocation，FDRA)，调制与编码策略(Modulation and coding scheme，MCS)。
在上述各实施例中，所述Msg3重复传输包括：随机接入响应RAR UL grant调度的物理上行共享信道PUSCH重复传输，或者，TC-RNTI加扰的PDCCH调度的重传。
需要说明的是，上述各实施例的终端行为是在终端选择了用于请求了Msg3重复传输的PRACH资源(包括PRACH preamble，PRACH occasion，PRACH配置configuration)的前提下执行的，优选的，进一步要求网络调度的Msg3 PUSCH重复传输次数大于1终端才会执行。
否则，终端如果未选择上述PRACH资源，或者网络未调度Msg3重复传输，则终端仍然执行不进行Msg3重复传输的行为。即如果成功接收到Msg4之后，无论竞争解决是否成功，终端都会清除HARQ buffer。对于竞争解决成功的终端，UE使用TC-RNTI作为C-RNTI；对于竞争解决不成功的终端，UE丢弃该TC-RNTI。
本申请实施例提供的随机接入过程的竞争解决方法，明确了具体的竞争解决信息指示方式和对应的UE行为，可以使竞争解决未成功的终端，提前终止未完成的Msg3重复传输，或者继续进行未完成的Msg3重复传输，不需要重新从PRACH(Msg1)开始尝试进行随机接入，降低了接入的时延。
