Abstract

Description

信息发送方法、信息接收方法、装置和系统 技术领域
本申请涉及通信领域。
背景技术
在当前通信网络中，终端设备通过Uu接口接入到网络部分，当前在Uu接口，系统信息(system information，SI)和寻呼消息(paging message)由网络(gNB)发送给终端设备(UE)。
系统信息包括主信息块(MIB)和系统信息块(SIB)。图1是系统信息获取示意图，如图1所示，网络设备向终端设备发送MIB和SIB1，对于其他系统信息，终端设备可以向网络设备侧发送系统信息请求，并接收网络设备侧发送的终端设备请求的系统信息，或者，也可以是网络设备主动向终端设备发送系统信息。
寻呼消息主要包括5G核心网(5GC)发起的移动被叫数据的寻呼以及无线接入网(RAN)发起的RAN寻呼，寻呼无线资源控制空闲(RRC_IDLE)或非激活状态(RRC_INACTIVE)中的终端设备。图2是寻呼过程示意图，如图2所示，网络设备向终端设备发送寻呼消息。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
在R17中已经开始研究边链路中继(SL relay)，图3中示出了边链路中继场景示意图，场景一中，远端终端设备(remote UE)不在基站或小区的覆盖范围内，中继终端设备(relay UE)在基站或小区的覆盖范围内，场景二中，远端终端设备和中继终端设备都在基站或小区的覆盖范围内，场景三中，远端终端设备和中继终端设备在不同基站或小区的覆盖范围内。其中，relay UE的Uu链路上使用NR(新无线)Uu，在relay UE和remote UE之间的PC5上使用NR边链路。
在上面的场景中，在Remote UE与Relay UE建立PC5接口的连接或者选择该 Relay UE后，Relay UE的服务小区可以被认为是Remote UE的服务小区。在Remote UE判断是否能够选择该Relay UE时，Remote UE需要判断是否能够驻留在该Relay UE的服务小区，因而Remote UE需要获得Relay UE的服务小区的系统信息；另一方面，在Remote UE已经通过Relay UE与gNB进行通信的情况下，如果服务小区的系统信息发生改变，Remote UE也需要获得服务小区的更新的系统信息。此外，在Remote UE已经与Relay UE建立PC5的单播链路之后，如果核心网或gNB要寻呼Remote UE，则Remote UE需要接收该寻呼消息。但发明人发现，目前在边链路上只支持使用边链路物理广播信道承载SL MIB，由于该信道承载的内容是有限的，目前不支持在边链路上发送除SL MIB外的其他系统信息，也不支持在边链路上发送寻呼消息。
为了解决上述问题的至少一种或其它类似问题，本申请实施例提供了一种信息发送方法、信息接收方法、装置和系统。
根据本申请实施例的一方面，提供一种信息发送装置，配置于第一网络设备，其中，该装置包括：
第一接收单元，其接收网络设备发送的第一系统信息和/或第一寻呼消息；
第一发送单元，其使用物理边链路共享信道向至少一个第二终端设备发送与该第一系统信息相关的第二系统信息和/或与该第一寻呼消息相关的第二寻呼消息。
根据本申请实施例的一方面，提供一种信息接收装置，配置于第二网络设备，其中，该装置包括：
第二接收单元，其使用物理边链路共享信道接收第一终端设备发送的与第一系统信息相关的第二系统信息和/或与第一寻呼消息相关的第二寻呼消息，其中，该第一系统信息和/或第一寻呼消息是该第一终端设备从网络设备侧接收的；
第三确定单元，其根据该第二系统信息确定是否驻留在该网络设备下的小区或该第一终端设备或该第一终端设备的服务小区或者确定是否接入该网络设备下的小区或者确定是否选择该第一终端设备作为中继设备或者确定是否与该第一终端设备建立边链路连接。
根据本申请实施例的一方面，提供一种信息发送装置，配置于网络设备，其中，该装置包括：
第四发送单元，其向终端设备发送与边链路系统信息和/或寻呼消息的发送相关 的配置信息和/或边链路授权。
本申请实施例的有益效果之一在于：除SL MIB外的其他系统信息和/或寻呼消息也可以被relay UE发送到remote UE，有益于remote UE保持与网络一致的配置和/或正确接收网络呼叫，从而可以确定是否可以驻留在网络设备下的小区或其他终端设备或其他终端设备的服务小区或者确定是否可以接入网络设备下的小区或者确定是否与其他终端设备建立边链路连接或者是否选择其他终端设备作为中继设备。

在一些实施例中，该第一终端设备可以使用单播或组播或广播的方式发送上述第二系统信息和/或第二寻呼消息，因此，发送的对象可以是一个第二终端设备(例如单播)，也可以是至少两个第二终端设备(组播或者广播)，关于发送方式的确定将在后述进行说明。
在一些实施例中，现有技术中使用SPBCH承载边链路MIB，在本申请实施例中可以使用物理边链路共享信道(PSSCH)发送该第二系统信息和/或第二寻呼消息，另外，可以使用边链路共享信道SL-SCH(传输信道)或新的传输信道来发送该第二系统信息和/或第二寻呼消息，由此，除SL MIB外的其他系统信息和/或寻呼消息也可以被relay UE发送到remote UE，有益于remote UE保持与网络一致的配置和/或正确接收网络呼叫。
在一些实施例中，可以使用PC5-RRC层消息承载该第二系统信息和/或第二寻呼消息，如图6所示，该第二系统信息和/或第二寻呼消息的转发在PC5接口依次经过第一终端设备的RLC,MAC,PHY,第二终端设备的PHY,MAC,RLC，以下分别对第一终端设备侧用于第二系统信息和/或第二寻呼消息发送的PC5的RLC,MAC层上的配置以及操作进行说明。
以下对RLC层相关配置进行说明。
在一些实施例中，用于该第二系统信息和/或该第二寻呼消息发送的RLC层信道或承载配置信息是被配置的(例如被网络设备配置或者被其他终端设备配置)或预定义的。
在一些实施例中，针对该至少一个第二终端设备的RLC层信道(SL RLC channel)或承载配置信息(SL-RLC-BearerConfig)相同或不同，例如，针对多于一个第二终端设备，配置相同或预定义相同的RLC层信道或承载配置信息被用于向至少两个(多于一个第二终端设备中的部分或所有)第二终端设备发送第二系统信息和/或第二寻呼消息；或者一个被配置的或预定义的RLC层信道或承载配置信息被用于向至少两个(多于一个第二终端设备中的部分或所有)第二终端设备发送第二系统信息和/或 第二寻呼消息；或者针对不同的第二终端设备，配置不同或预定义不同的RLC层信道或承载配置信息被用于向各个第二终端设备发送第二系统信息和/或第二寻呼消息；或者也可以以上至少两种方式结合，例如针对多于一个第二终端设备，一部分使用相同的RLC层信道或承载配置信息一部分使用不同的RLC层信道或承载配置信息，本申请实施例并不以此作为限制。再例如，针对一个第二终端设备，配置不同或预定义不同的RLC层信道或承载配置信息被用于发送第二系统信息和第二寻呼消息，也即针对同一个第二终端设备，用于第二系统信息发送的RLC层信道或承载配置信息与用于第二寻呼消息发送的RLC层信道或承载配置信息不同。
在一些实施例中，RLC层信道或承载配置信息相同表示RLC层信道或承载配置信息中的各个信息都相同，RLC层信道或承载配置信息不相同表示RLC层信道或承载配置信息中的部分信息不同，或者全部信息不同。该RLC层信道或承载配置信息可以包括RLC承载配置索引，以及该信道对应的RLC配置和/或逻辑信道配置等，例如，RLC层信道或承载配置信息不相同可以是RLC承载配置索引不同，即配置不同的RLC承载配置索引被用于向各个第二终端设备发送第二系统信息和/或第二寻呼消息，不同的第二终端设备对应的RLC信道或承载不同；例如，RLC层信道或承载配置信息不相同可以是RLC承载配置索引相同，但RLC信道配置和/或逻辑信道配置不同，即不同的第二终端设备对应的相同的RLC承载配置索引，但对应不同的RLC信道配置和/或逻辑信道配置，此处不再一一举例。
在一些实施例中，在该配置信息是预定义时，上述RLC层信道或承载配置信息会预定义在第一终端设备中，第一终端设备根据上述配置即可以确定针对一个第二终端设备使用的RLC信道或承载，在该配置信息是被配置时，该方法还可以包括(未图示)：该第一终端设备接收该网络设备或其他终端设备发送的该RLC层信道或承载配置信息，在该配置信息是被网络设备配置时，该RLC层信道或承载配置信息由RRC层消息承载，在该配置信息是被其他终端设备(例如第二终端设备)配置时，该RLC层信道或承载配置信息由PC5信令层(PC5Signalling，PC5-S)消息或边链路RRC层消息(PC5-RRC)承载，第一终端设备根据接收到的上述配置即可以选择或建立针对一个第二终端设备使用的RLC信道或承载。
在一些实施例中，在需要建立RLC信道或承载时，该方法还包括(未图示)：该第一终端设备接收网络设备或其他终端设备发送的RLC信道或承载建立指示信息， 其中，可以将前述RLC信道或承载配置信息可以包含在该RLC信道或承载建立指示信息中，该第一终端设备可以根据该RLC信道或承载建立指示信息建立用于该第二系统信息和/或该第二寻呼消息发送的RLC信道或承载，该RLC信道或承载建立指示信息中包含的RLC承载配置索引是第一终端设备侧中没有被预定义或配置过的RLC承载配置索引。
在一些实施例中，RLC层信道或承载配置信息包括RLC配置和/或逻辑信道配置，其中，在该RLC配置中，用于第二系统信息和/或第二寻呼消息发送的RLC配置为透明模式(Transparent Mode，TM)，即不对传入RLC的第二系统信息和/或第二寻呼消息做任何处理，直接透传；在逻辑信道配置中，包括用于第二系统信息和/或第二寻呼消息发送的逻辑信道优先级配置，另外，可以不必须包括(即可以不包括或可选地包括)优先比特速率(sl-PrioritisedBitRate，PBR)配置和令牌桶大小(sl-BucketSizeDuration)配置，或者可以将PBR设置或预定义为无穷大，或者可以将令牌桶大小设置或预定义为无穷大。其中，该用于第二系统信息和/或第二寻呼消息发送的逻辑信道优先级可以被配置为最高，例如用“1”表示最高优先级，但本申请实施例并不以此作为限制。
以下对MAC层相关配置和操作进行说明。
在一些实施例中，该第二系统信息和/或第二寻呼消息对应的逻辑信道的数据不与其他逻辑信道的数据复用在一个边链路MAC协议数据单元(SL MAC PDU)或传输块(Transport block)中。
在一些实施例中，用于该第二系统信息和/或该第二寻呼消息发送的目的标识是被配置(被网络设备或第二终端设备配置)的或预定义的，或是边链路发现消息的传输使用的目的标识，或是与该第二终端设备进行单播通信使用的目的标识。该目的标识是目的层2标识(destination L2 ID)，目的层1标识(destination L1 ID)，源层2目的标识和目的层2标识对(a pair of source L2 ID and destination L2 ID)中的任一个。
在一些实施例中，在该目的标识是被配置的时，该方法还可以包括：(未图示)该第一终端设备接收网络侧(例如是5GC或gNB)或第二终端设备发送的用于该第二系统信息和/或该第二寻呼消息发送的目的标识配置信息，在该目的标识配置信息是被网络侧配置时，该目的标识配置信息由RRC层消息承载，在该目的标识配置信息是被其他终端设备(例如第二终端设备)配置时，该目的标识配置信息由边链路信 令层消息或边链路RRC层消息(例如PC5-S或PC5-RRC)承载，例如第一边链路发现消息承载，该第一边链路发现消息可以是边链路发现请求消息或边链路发现确认消息。
在一些实施例中，该方法还可以包括：(未图示)该第一终端设备向第二终端设备发送第二边链路发现消息，该用于该第二系统信息和/或该第二寻呼消息发送的目的标识是发送该第二边链路发现消息使用的目的标识，该第二边链路发现消息可以是边链路发现请求消息或边链路发现确认消息。
在一些实施例中，在第一终端设备与第二终端设备建立连接的情况下，该目的标识可以是预定义的，或者是网络侧配置的目的标识，或者是边链路发现消息通知或配置的目的标识，或者是边链路发现消息的传输使用的目的标识，或是与该第二终端设备进行单播通信使用的目的标识，否则，该目的标识可以是预定义的，或者是网络侧配置的目的标识，或者是边链路发现消息通知或配置的目的标识，或者是边链路发现消息的传输使用的目的标识，本实施例并不以此作为限制。
在一些实施例中，第一终端设备可以自己确定发送第二系统信息和/或第二寻呼消息使用的发送类型(cast type)。例如，该第一终端设备可以根据与该第二终端设备建立单播链路的时机，或根据该第二终端设备的数量，或根据建立的PC5 RRC连接的数量，或根据资源池的负载，或根据该第二系统信息的内容确定该第二系统信息和/或该第二寻呼消息的发送类型，该发送类型包括单播(unicast)和/或组播(groupcast)和/或广播(broadcast)。
例如，该第一终端设备可以根据与该第二终端设备建立单播链路的时机确定该第二系统信息和/或该第二寻呼消息的发送类型，在第一终端设备和第二终端设备的单播链路被建立之前，发送类型为广播，或者在第一终端设备和第二终端设备的单播链路被建立之后，发送类型为单播或组播或广播。
例如，该第一终端设备可以根据第二终端设备的数量确定该第二系统信息和/或该第二寻呼消息的发送类型，当多于或等于第一数量的第二终端设备请求该第二系统信息时，发送类型为广播或组播，或者当低于第一数量的第二终端设备请求该第二系统信息时，发送类型为单播，或者，当多于或等于第二数量的第二终端设备与第一终端设备具有PC5连接时，发送类型为广播或组播，或者当低于第二数量的第二终端设备与第一终端设备具有PC5连接时，发送类型为单播，该第一数量和/或第二数量 可以是预定义的值，也可以是网络配置的值。
例如，该第一终端设备可以根据建立的PC5 RRC连接的数量确定该第二系统信息和/或该第二寻呼消息的发送类型，当该第一终端设备具有多于或等于第三数量的PC5 RRC连接时，发送类型为广播或组播，或者该第一终端设备具有低于第三数量的PC5 RRC连接时，发送类型为单播，该第三数量可以是预定义的值，也可以是网络配置的值。
例如，该第一终端设备可以根据资源池的负载确定该第二系统信息和/或该第二寻呼消息的发送类型，其中，资源池的负载可以是该资源池的信道忙率(Channel Busy Ratio，CBR)或信道占用率(Channel occupancy ratio，CR)或物理资源块(Physical Resource Block，PRB)的占用率等，CBR或CR或PRB占用率的具体计算方法可以参考现有技术。当第二系统信息和/或该第二寻呼消息所使用的发送资源池的负载高于或等于第一门限时，发送类型为广播或组播，或者当第二系统信息和/或该第二寻呼消息所使用的发送资源池的负载低于第一门限时，发送类型为单播。
例如，该第一终端设备可以根据该第二系统信息的内容确定该第二系统信息和/或该第二寻呼消息的发送类型，当该第二系统信息的内容与第二终端设备确定是否驻留在该网络设备下的小区或该第一终端设备或该第一终端设备的服务小区或者确定是否接入该网络设备下的小区或者确定是否选择该第一终端设备作为中继设备或者确定是否与该第一终端设备建立边链路连接有关时，发送类型为广播，或者当该第二系统信息的内容与第二终端设备确定是否驻留在该网络设备下的小区或该第一终端设备或该第一终端设备的服务小区或者确定是否接入该网络设备下的小区或者确定是否选择该第一终端设备作为中继设备或者确定是否与该第一终端设备建立边链路连接无关时，发送类型为单播，例如当第二系统信息为公共陆地移动网(Public Land Mobile Network，PLMN)标识，小区标识(Cell ID)，接入控制信息中的至少一个时，发送类型为广播，或者当第二系统信息为按需系统信息(on-demand SI)等时，发送类型为单播，此处不再一一举例。
在一些实施例中，发送第二系统信息和/或第二寻呼消息使用的发送类型可以由网络侧指示，该方法还包括(未图示)：该第一终端设备接收该网络设备发送的用于该第二系统信息和/或该第二寻呼消息发送的发送类型配置信息，该发送类型包括单播和/或组播和/或广播，该发送类型配置信息可以由RRC层消息承载。此外，该发送 类型配置信息可以包括第二系统信息中一个SI消息或SIB或参数的特定的发送类型。
在一些实施例中，以上RRC层消息可以是RRC重配置消息，RRC恢复消息，RRC建立消息，RRC重建立消息(RRC reconfiguration、RRC resume、RRC setup、RRC re-establishment)等，本申请实施例并不以此作为限制。
在一些实施例中，该第一终端设备的MAC层会将逻辑信道的数据映射到传输信道，即将RLC PDU放到MAC PDU中，通过物理层发送出去，对于一个用于新传输的边链路授权(SL grant)，MAC层需要进行逻辑信道优先级处理(Logical Channel Prioritization，LCP)。图8是逻辑信道优先级过程场景示意图，如图8所示，该第一终端设备在逻辑信道优先级过程中需要选择目的地(destination)，例如，选择Remote UE1或者Remote UE2作为目的地，以下说明如何选择。
在一些实施例中，该第一终端设备根据各逻辑信道的逻辑信道优先级配置确定逻辑信道优先级过程中的目的地。例如选择优先级最高的逻辑信道对应的目的地，该发送第二系统信息和/或第二寻呼消息的逻辑信道的逻辑信道优先级可以在如前所述的RLC层信道或承载配置信息中确定，如果将发送该第二系统信息和/或第二寻呼消息发送的逻辑信道的逻辑信道优先级配置为最高(例如1)，则该第一终端设备选择该发送第二系统信息和/或第二寻呼消息的逻辑信道所在的目的地，但该逻辑信道优先级配置中令牌不必须大于0。
以下说明如何确定用于该第二系统信息和/或第二寻呼消息发送的资源。
在一些实施例中，在资源模式1中，网络设备可以为第一终端设备分配用于该第二系统信息和/或该第二寻呼消息发送的边链路授权，在该方式中，该方法可以包括：(未图示)第一终端设备接收该网络设备使用下行控制信道发送的用于该第二系统信息和/或该第二寻呼消息发送的边链路授权。其中，网络设备可以通过显示或隐式的方式指示该分配的边链路授权是用于该第二系统信息和/或该第二寻呼消息的发送。例如，该下行控制信道可以寻址特定的无线网络临时标识RNTI，由此隐式的指示该边链路授权是用于该第二系统信息和/或该第二寻呼消息的发送；或者该下行控制信道被分配特定的搜索空间和/或控制资源集合，由此隐式的指示该边链路授权是用于该第二系统信息和/或该第二寻呼消息的发送；或者，在该下行控制信道的DCI中承载该边链路授权，该DCI中还包括第一指示信息，该第一指示信息用于指示该边链路授权用于该第二系统信息和/或该第二寻呼消息的发送，由此，通过该第一指示信 息显示的指示该边链路授权是用于该第二系统信息和/或该第二寻呼消息的发送，该第一指示信息可以是新增的信息元(IE)或域(field)。
在一些实施例中，在资源模式2中，在有该第二系统信息和/或该第二寻呼消息要发送时，该第一终端设备从资源池中选择用于该第二系统信息和/或该第二寻呼消息发送的资源。例如，该资源池可以是被配置的或者预定义的用于第二系统信息和/或该第二寻呼消息发送的特定资源池，在该资源池是被配置时，该方法还可以包括：(未图示)该第一终端设备接收该网络设备发送的该资源池配置信息，也就是说，在有该第二系统信息和/或该第二寻呼消息要发送时，该第一终端设备从该特定资源池中选择用于该第二系统信息和/或该第二寻呼消息发送的资源。例如，为第二系统信息的发送配置的资源池与为第二寻呼消息的发送配置的资源池相同或不同，即可以为第二系统信息配置一个发送资源池，为第二寻呼消息配置另一个发送资源池，也可以为第二系统信息和第二寻呼消息配置同一个发送资源池。
在一些实施例中，在有该第二系统信息和/或该第二寻呼消息以及其他边链路数据要发送时，该第一终端设备先从资源池中选择用于该第二系统信息和/或该第二寻呼消息发送的资源。该资源池可以使用现有的方法配置，也可以是网络设备配置的用于第二系统信息和/或该第二寻呼消息发送的特定资源池，本申请实施例并不以此作为限制。
在一些实施例中，网络设备可以根据第一终端设备发送的调度请求和待发送的边链路数据量(边链路缓存状态报告)来分配边链路授权，图9是发送调度请求和BSR场景示意图，如图9所示，在发送第二系统信息和/或第二寻呼消息前，该第一终端设备向网络设备发送调度请求(SR)和/或边链路缓存状态报告(SL-BSR)，以便网络设备分配边链路授权，该第二系统信息和/或该第二寻呼消息对应的逻辑信道的SR配置信息可以是特定的，或者也可以使用其他逻辑信道和/或MAC CE对应的SR配置信息(即该第二系统信息和/或该第二寻呼消息对应的逻辑信道的SR配置信息与其他逻辑信道和/或MAC CE对应的配置信息相同)。
例如，在该第二系统信息和/或该第二寻呼消息对应的逻辑信道的SR配置信息可以是特定的时，该方法还可以包括：该第一终端设备接收该网络设备发送的该第二系统信息和/或该第二寻呼消息对应的逻辑信道的SR配置信息(特定的SR配置信息)，例如，第二系统信息对应的逻辑信道对应的逻辑信道的SR配置信息与第二寻呼消息 对应的逻辑信道对应的逻辑信道的SR配置信息可以被配置为相同或不同，即可以为该第二系统信息配置一个SR配置信息，也可以为该第二寻呼消息配置另一个SR配置信息，还可以为第二系统信息和第二寻呼消息配置同一个SR配置信息，该SR配置信息中包括为第一终端设备分配的调度请求资源，例如物理上行控制信道(PUCCH)资源集合。
在一些实施例中，在边链路缓存状态报告中，第二系统信息和/或该第二寻呼消息对应的逻辑信道所在的逻辑信道组(LCG)的标识可以是被配置的或者预定义的特定LCG，例如，第二系统信息对应的逻辑信道所在的逻辑信道组(LCG)的标识与第二寻呼消息对应的逻辑信道所在的逻辑信道组(LCG)的标识可以被配置或预定义为相同或不同，可以为该第二系统信息配置或预定义一个LCG，为该第二寻呼消息配置或预定义另一个LCG，还可以为第二系统信息和第二寻呼消息配置或预定义同一个LCG。在该逻辑信道组的标识是被配置的时，该方法还可以包括(未图示)：该第一终端设备接收该网络设备的发送的该第二系统信息和/或该第二寻呼消息对应的逻辑信道所在的逻辑信道组标识配置信息。网络设备在收到该边链路BSR后，如果其包含的LCG是该网络设备之前配置的特定LCG或者是预定义的特定LCG，则可以确定该特定LCG对应的缓存大小(buffer size)对应的是第二系统信息和/或该第二寻呼消息的数据量。
在一些实施例中，在边链路缓存状态报告中，还可以直接上报该第二系统信息和/或该第二寻呼消息对应的逻辑信道具有的缓存大小。
在一些实施例中，在该第二系统信息和/或该第二寻呼消息对应的逻辑信道有数据待发送时，触发该第一终端设备发送边链路缓存状态报告。或者，如果在RLC层信道或承载配置信息中配置了该第二系统信息和/或该第二寻呼消息对应的逻辑信道的逻辑信道优先级时，可以使用现有的边链路缓存状态报告触发条件触发该边链路缓存状态报告，例如，在更高优先级的逻辑信道有数据到达时，或者在所有逻辑信道没有数据而有一个逻辑信道有新数据到达时，触发该边链路缓存状态报告。
在一些实施例中，该方法还可以包括：(未图示)该第一终端设备向该第二终端设备发送用于该第二系统信息和/或该第二寻呼消息接收的RLC层信道或承载配置信息，和/或目的标识配置信息，该第二终端设备根据该第一终端设备的配置确定用于该第二系统信息和/或该第二寻呼消息接收的PC5-RLC层配置或逻辑信道配置，以及 确定用于该第二系统信息和/或该第二寻呼消息发送的目的标识。
由此，除SL MIB外的其他系统信息和/或寻呼消息也可以被relay UE发送到remote UE，有益于remote UE保持与网络一致的配置和/或正确接收网络呼叫，从而可以确定是否可以驻留在网络设备下的小区或其他终端设备或其他终端设备的服务小区或者确定是否可以接入网络设备下的小区或者确定是否与其他终端设备建立边链路连接或者是否选择其他终端设备作为中继设备。
第二方面的实施例
本申请实施例提供一种信息接收方法，应用于第二终端设备侧，该第一终端设备可以是Relay UE，该第二终端设备可以是Remote UE。
图10是该信息接收方法示意图，如图10所示，该方法包括：
1001，第二终端设备使用物理边链路共享信道接收第一终端设备发送的与第一系统信息相关的第二系统信息和/或与第一寻呼消息相关的第二寻呼消息，其中，该第一系统信息和/或第一寻呼消息是该第一终端设备从网络设备侧接收的；
1002，该第二终端设备根据该第二系统信息确定是否驻留在该网络设备下的小区或该第一终端设备或该第一终端设备的服务小区或者确定是否接入该网络设备下的小区或者确定是否选择该第一终端设备作为中继设备或者确定是否与该第一终端设备建立边链路连接。
在一些实施例中，1001的实施方式与第一方面的实施例中702对应，重复之处不再赘述。
在一些实施例中，在1002中，该第二终端设备可以根据该第二系统信息确定是否驻留在该网络设备下的小区或该第一终端设备或该第一终端设备的服务小区或者确定是否接入该网络设备下的小区或者确定是否选择该第一终端设备作为中继设备或者确定是否与该第一终端设备建立边链路连接(包括SL连接或SL单播链路或PC5RRC连接)。例如，根据第二系统信息中的PLMN ID、TAC、TAI、cell barring指示等确定是否能驻留在该网络设备下的小区或该第一终端设备或该第一终端设备的服务小区，根据第二系统信息中的UAC配置确定是否接入该网络设备下的小区，根据T300和T301的配置确定执行接入的时间，根据该小区是否支持SL relay操作确定是否与该第一终端设备建立边链路连接，进一步的，还可以根据该小区的SL相关信息 确定SL消息发送或接收使用的资源池等。
在一些实施例中，现有技术中使用SPBCH承载边链路MIB，在本申请实施例中可以使用物理边链路共享信道(PSSCH)接收该第二系统信息和/或第二寻呼消息，另外，可以使用边链路共享信道SL-SCH(传输信道)或新的传输信道来发送该第二系统信息和/或第二寻呼消息，由此，除SL MIB外的其他系统信息和/或寻呼消息也可以被relay UE发送到remote UE，有益于remote UE保持与网络一致的配置和/或正确接收网络呼叫。
在一些实施例中，可以使用PC5-RRC层消息承载该第二系统信息和/或第二寻呼消息，如图6所示，该第二系统信息和/或第二寻呼消息在PC5接口的转发依次经过第一终端设备的RLC,MAC,PHY,第二终端设备的PHY,MAC,RLC，以下分别对第二终端设备侧用于第二系统信息和/或第二寻呼消息接收的PC5的RLC,MAC层上的配置进行说明。
以下对RLC层相关配置进行说明。
在一些实施例中，用于该第二系统信息和/或该第二寻呼消息接收的RLC层信道或承载配置信息是被配置的(例如被网络设备配置或者被其他终端设备配置)或预定义的。
在一些实施例中，针对该第二终端设备的RLC层信道(SL RLC channel)或承载配置信息(SL-RLC-BearerConfig)与其他第二终端设备的RLC层信道(SL RLC channel)或承载配置信息(SL-RLC-BearerConfig)相同或不同，例如，针对该第二终端设备与其他第二终端设备，配置相同或预定义相同的RLC层信道或承载配置信息被用于该第二系统信息和/或该第二寻呼消息接收；或者针对该第二终端设备与其他第二终端设备，配置不同或预定义不同的RLC层信道或承载配置信息被用于该第二系统信息和/或该第二寻呼消息接收；或者也可以以上至少两种方式结合，例如针对该第二终端设备与其他第二终端设备，一部分使用相同的RLC层信道或承载配置信息一部分使用不同的RLC层信道或承载配置信息，本申请实施例并不以此作为限制。再例如，针对该第二终端设备，配置不同或预定义不同的RLC层信道或承载配置信息被用于发送第二系统信息和第二寻呼消息，也即针对该第二终端设备，用于第二系统信息接收的RLC层信道或承载配置信息与用于第二寻呼消息接收的RLC层信道或承载配置信息不同。
在一些实施例中，RLC层信道或承载配置信息相同表示RLC层信道或承载配置信息中的各个信息都相同，RLC层信道或承载配置信息不相同表示RLC层信道或承载配置信息中的部分信息不同，或者全部信息不同。该RLC层信道或承载配置信息可以包括RLC承载配置索引，以及该信道对应的RLC配置和/或逻辑信道配置等，例如，RLC层信道或承载配置信息不相同可以是RLC承载配置索引不同，即针对该第二终端设备与其他第二终端设备，配置不同的RLC承载配置索引被用于接收第二系统信息和/或第二寻呼消息，不同的第二终端设备对应的RLC信道或承载不同；例如，RLC层信道或承载配置信息不相同可以是RLC承载配置索引相同，但RLC信道配置和/或逻辑信道配置不同，即针对该第二终端设备与其他第二终端设备，对应的相同的RLC承载配置索引，但对应不同的RLC信道配置和/或逻辑信道配置，此处不再一一举例。
在一些实施例中，在该配置信息是预定义时，上述RLC层信道或承载配置信息会预定义在第一终端设备中，第一终端设备根据上述配置即可以确定针对一个第二终端设备使用的RLC信道或承载，在该配置信息是被配置时，该方法还可以包括(未图示)：该第二终端设备接收该网络设备或其他终端设备发送的该RLC层信道或承载配置信息，在该配置信息是被网络设备配置时，该RLC层信道或承载配置信息由RRC层消息承载，在该配置信息是被其他终端设备(例如第一终端设备)配置时，该RLC层信道或承载配置信息由PC5信令层(PC5Signalling，PC5-S)消息或边链路RRC层消息(PC5-RRC)承载，第二终端设备根据接收到的上述配置即可以选择或建立接收第二系统信息和/或第二寻呼消息使用的RLC信道或承载。
在一些实施例中，在需要建立RLC信道时，该方法还包括(未图示)：该第二终端设备接收网络设备或其他终端设备发送的RLC信道或承载建立指示信息，其中，可以将前述RLC信道或承载配置信息可以包含在该RLC信道或承载建立指示信息中，该第二终端设备可以根据该RLC信道或承载建立指示信息建立用于该第二系统信息和/或该第二寻呼消息接收的RLC信道或承载，该RLC信道或承载建立指示信息中包含的RLC承载配置索引是第一终端设备侧中没有被预定义或配置过的RLC承载配置索引。
在一些实施例中，RLC层信道或承载配置信息包括RLC配置和/或逻辑信道配置，其中，在该RLC配置中，用于第二系统信息和/或第二寻呼消息接收的RLC配置为 透明模式(Transparent Mode，TM)，即不对传入RLC的第二系统信息和/或第二寻呼消息做任何处理，直接透传。
以下对MAC层相关配置和操作进行说明。
在一些实施例中，用于该第二系统信息和/或该第二寻呼消息发送的目的标识是被配置(被网络设备或第一终端设备配置)的或预定义的，或是边链路发现消息的传输使用的目的标识，或是与该第一终端设备进行单播通信使用的目的标识。该目的标识是目的层2标识，目的层1标识，源层2目的标识和目的层2标识对(a pair of source L2 ID and destination L2 ID)中的任一个。
在一些实施例中，在该目的标识是被配置的时，该方法还可以包括：(未图示)该第二终端设备接收网络侧(例如是5GC或gNB)或第一终端设备发送的用于该第二系统信息和/或该第二寻呼消息发送的目的标识配置信息，在该目的标识配置信息是被网络侧配置时，该目的标识配置信息由RRC层消息承载，在该目的标识配置信息是被其他终端设备(例如第一终端设备)配置时，该目的标识配置信息由边链路信令层消息或边链路RRC层消息(例如PC5-S或PC5-RRC)承载，例如第一边链路发现消息承载，该第一边链路发现消息可以是边链路发现请求消息或边链路发现确认消息。
在一些实施例中，该方法还可以包括：(未图示)该第二终端设备接收第一终端设备发送的第二边链路发现消息，该用于该第二系统信息和/或该第二寻呼消息发送的目的标识是接收该第二边链路发现消息使用的目的标识，该第二边链路发现消息可以是边链路发现请求消息或边链路发现确认消息。
在一些实施例中，在第二终端设备与第一终端设备建立连接的情况下，该目的标识可以是预定义的，或者是网络侧配置的目的标识，或者是边链路发现消息通知或配置的目的标识，或者是边链路发现消息的传输使用的目的标识，或是与该第一终端设备进行单播通信使用的目的标识，否则，该目的标识可以是预定义的，或者是网络侧配置的目的标识，或者是边链路发现消息通知或配置的目的标识，或者是边链路发现消息的传输使用的目的标识，本实施例并不以此作为限制。
在一些实施例中，该方法还可以包括：(未图示)该第二终端设备向该第一终端设备发送用于该第二系统信息和/或该第二寻呼消息发送的RLC层信道或承载配置信息，和/或目的标识配置信息，该第一终端设备根据该第二终端设备的配置确定用于 该第二系统信息和/或该第二寻呼消息发送的PC5-RLC层配置或逻辑信道配置，以及确定用于该第二系统信息和/或该第二寻呼消息发送的目的标识。
由此，除SL MIB外的其他系统信息和/或寻呼消息也可以被relay UE发送到remote UE，有益于remote UE保持与网络一致的配置和/或正确接收网络呼叫，从而可以确定是否可以驻留在网络设备下的小区或其他终端设备或其他终端设备的服务小区或者确定是否可以接入网络设备下的小区或者确定是否与其他终端设备建立边链路连接或者是否选择其他终端设备作为中继设备。
