Description

处理无线链路失败方法、终端设备和网络设备
本申请要求于2017年6月16日提交中国专利局、申请号为201710458408.7、申请名称为“处理无线链路失败方法、终端设备和基站”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，并且更具体地，涉及处理无线链路失败方法、终端设备和网络设备。
背景技术
为了增加数据包传输的可靠性，业界提出了重复传输数据包的方案。具体地，终端设备可以使用两个载波向该基站发送两个相同的数据包。这样，只要该基站成功接收到该两个相同的数据包中的一个数据包，该基站就可以成功接收到该终端设备需要发送给该基站的数据包。
终端设备在于基站通信的过程中，可能会发生无线链路失败(radio link failure，RLF)事件。若发生RLF事件，则该终端设备会进行无线资源控制(radio resource control，RRC)重建过程，以修复该终端设备与该基站之间的无线链路。但是目前的基于RLF事件的RRC重建过程仅考虑到终端设备使用一个载波与基站通信的场景，并未考虑到上述重复传输数据包的场景。因此，在重复传输数据包的场景中如何处理RLF事件是一个亟待解决的问题。
发明内容
本申请提供一种处理无线链路失败、终端设备和基站，能够优化无线链路失败的处理。
第一方面，本申请实施例提供一种处理RLF方法，该方法包括：终端设备通过第一载波和第二载波向基站发送相同的数据包；该终端设备在确定该第一载波和该第二载波中的至少一个发生RLF事件的情况下，向该基站发送RLF指示信息，该RLF指示信息用于指示该第一载波、该第二载波，或者该第一载波和该第二载波发生该RLF事件。基于上述技术方案，终端设备在确定部分或全部载波发生RLF事件的情况下，可以先将发生RLF事件的载波通知给基站，而无需启动RRC重建过程。
结合第一方面，在第一方面的第一种可能的实现方式中，该第一载波为第一主载波，该第二载波为第一辅载波，该方法还包括：在该第一载波发生该RLF事件且该第二载波未发生该RLF事件的情况下，该终端设备接收该基站发送的第二主载波的配置信息，并通过该第二主载波和该第二载波向该基站发送相同的数据包；在该第一载波未发生该RLF事件且该第二载波发生该RLF事件的情况下，该终端设备接收该基站发送的第二辅载波的配置信息，并通过该第一载波和该第二辅载波向该基站发送相同的数据包；在该第一载 波和该第二载波均发生该RLF事件的情况下，该终端设备接收该基站发送的该第二主载波的配置信息和该第二辅载波的配置信息，并通过该第二主载波和该第二辅载波向该基站发送相同的数据包。基于上述技术方案，终端设备在确定部分或全部载波发生RLF事件的情况下，该终端设备可以使用其他载波继续相同的数据包，而无需启动RRC重建过程。因此，可以减少进行RRC重建的次数，避免进行RRC重建导致的时间消耗。
结合第一方面，在第一方面的第二种可能的实现方式中，该第一载波为第一辅载波，该第二载波为第二辅载波，该方法还包括：在该第一载波和该第二载波中的一个发生该RLF事件且该第一载波和该第二载波中的另一个未发生该RLF事件的情况下，该终端设备接收第三辅载波的配置信息，并通过该第三辅载波和未发生该RLF事件的载波向该基站发送相同的数据包；在该第一载波和该第二载波均发生该RLF事件的情况下，该终端设备接收该第三辅载波的配置信息和第四辅载波的配置信息，并通过该第三辅载波和该第四辅载波向该基站发送相同的数据包。基于上述技术方案，终端设备在确定部分或全部载波发生RLF事件的情况下，该终端设备可以使用其他载波继续发送相同的数据包，而无需启动RRC重建过程。因此，可以减少进行RRC重建的次数，避免进行RRC重建导致的时间消耗。
结合第一方面，在第一方面的第三种可能的实现方式中，该第一载波为第一主载波，该第二载波为第一辅载波，该方法还包括：在该第一载波发生RLF事件的情况下，接收该终端设备发送重建指示信息并与该基站进行RRC重建，该重建指示信息用于指示该终端设备与该基站进行RRC重建；在该第一载波未发生该RLF事件且该第二载波发生该RLF事件的情况下，该终端设备接收该基站发送的第二辅载波的配置信息，并通过该第一载波和该第二辅载波向该基站发送相同的数据包。基于上述技术方案，终端设备仅在主载波发生RLF事件的情况下进行RRC重建。因此，可以减少进行RRC重建的次数，避免进行RRC重建导致的时间消耗。
结合第一方面的第一种可能的实现方式，在第一方面的第四种可能的实现方式中，在该基站为辅基站且该第一载波发生该RLF事件的情况下，该向该基站发送RLF指示信息包括：该终端设备在确定定时器超时且该终端设备未恢复使用该第一载波向该基站发送数据包的情况下，向该基站发送该RLF指示信息，其中该定时器是在该终端设备确定该第一载波发生该RLF事件时启动的。基于上述技术方案，终端设备可以仅在定时器超时且未恢复通信时向该基站发送该RLF指示信息。若该定时器超时前该终端设备恢复使用该第一载波向该基站发送数据包，则无需向该基站发送该RLF指示信息。因此，上述技术方案可以减少不必要的RLF指示信息的发送。
结合第一方面或第一方面的上述任一种可能的实现方式，在第一方面的第五种可能的实现方式中，该方法还包括：该终端设备在确定该第一载波和第二载波中的至少一个发生RLF事件的情况下，向该基站发送以下信息中的至少一个：该RLF事件、多个载波的下行信道质量，和该终端设备确定的候选载波。通过上述技术方案可以帮助基站确定切换的载波。

结合第一方面或第一方面的上述任一种可能的实现方式，在第一方面的第八种可能的实现方式中，在该终端设备通过第一载波和第二载波向基站发送相同的数据包之前，该方法还包括：该终端设备接收该基站发送的第一阈值和第二阈值；该终端设备根据多个载波的传输参数、该第一阈值，和该第二阈值，从该多个载波中确定该第一载波和该第二载波，其中该第一载波的传输参数满足该第一阈值，该第二载波的传输参数满足该第二阈值，该传输参数包括以下中的一个或多个：载波的信道质量、载波的负载、载波的传输错误率，和载波中能够传输的数据包大小；该终端设备向该基站发送载波指示信息，该载波指示信息用于指示该终端设备确定的用于进行数据包重复传输的载波。上述技术方案中，基站半静态地指示该终端设备可以选择的用于进行数据包重复传输的载波。这样，该终端设备可以有一定的选择用于进行数据包重复传输的载波的权利。
结合第一方面或第一方面的上述任一种可能的实现方式，在第一方面的第九种可能的实现方式中，该终端设备通过第一载波和第二载波向该基站发送相同的数据包，包括：该终端设备将待发送的第一数据包复制，得到第二数据包；该终端设备通过该第一载波将该第一数据包发送至该基站；该终端设备通过该第二载波将该第二数据包发送至该基站。基于上述技术方案，两个相同的数据包只要有一个成功传输，该基站就能够获取到期望得到的数据包。因此，上述技术方案增加了数据包传输的可靠性。

结合第二方面，在第二方面的第一种可能的实现方式中，该第一载波为第一主载波，该第二载波为第一辅载波，该方法还包括：该基站在确定该第一载波发生该RLF事件且该第二载波未发生该RLF事件的情况下，将第三辅载波配置为第二主载波，向该终端设备发送该第二主载波的配置信息，并接收该终端设备通过该第二主载波和该第二载波发送的相同的数据包；该基站在确定该第一载波未发生该RLF事件且该第二载波发生该RLF事件的情况下，向该终端设备发送该第二辅载波的配置信息，并接收该终端设备通过该第一载波和该第二辅载波发送的相同的数据包；该基站在确定该第一载波和该第二载波均发生该RLF事件的情况下，将第三辅载波配置为该第二主载波，并向该终端设备发送该第二主载波的配置信息和该第二辅载波的配置信息，并接收该终端设备通过该第二主载波和该第二辅载波发送的相同的数据包。基于上述技术方案，在部分或全部载波发生RLF事件的情况下，该基站可以使用其他载波继续接收该终端设备发送的相同的数据包，而无需 启动RRC重建过程。因此，可以减少进行RRC重建的次数，避免进行RRC重建导致的时间消耗。

图2是根据本申请实施例提供的一种处理RLF的方法的示意性流程图。
201，终端设备通过第一载波和第二载波向基站发送相同的数据包。
具体地，终端设备可以将待发送的第一数据包复制，得到第二数据包，然后通过该第一载波将该第一数据包发送至该基站，通过第二载波将该第二数据包发送至该基站。
本申请实施例中所称的第一载波可以是一个载波，也可以是包括多个载波的一个载波组。本申请实施例中所称的第二载波可以是一个载波，也可以是包括多个载波的一个载波组。在第一载波是主载波或者包含一个主载波的情况下，可以称其为第一主载波；在第一载波不包含主载波的情况下。可以称其为第一辅载波；第二、第三载波等情况类似。本申请实施例中所称的第一载波、第二载波、第一主载波、第二辅载波等中的“第一”和“第二”仅是为了区分不同的载波、主载波和辅载波。
可选的，在一些实施例中，该终端设备可以仅通过该第一载波和该第二载波向基站发送相同的数据包。
可选的，在另一些实施例中，该终端设备还可以通过M个载波向该基站发送相同的数据包，其中M为大于或等于3的正整数。在此情况下，该终端设备可以将待发送的第一数据包复制，得到包括该第一数据包在内的M个数据包，分别通过该M个载波将该M个相同的数据包发送至基站，从而进一步提高数据传输的可靠性。该终端设备在通过M个载波向该基站发送相同的数据包的情况下处理RLF的方法与该终端设备在通过两个载波向基站发送相同的数据包的情况下处理RLF的方式类似。换句话说，该第一载波和该第二载波可以是该M个载波中的任意两个载波。
可选的，在另外一些实施例中，比如双连接场景下，所述载波可以是指与不同基站之间的连接(link)，所述基站可以是主基站或者辅基站。此时，在第一载波是主基站的主 载波或者包含一个主基站的主载波的情况下，可以称其为第一主载波；在第一载波不包含主基站的主载波的情况下。可以称其为第一辅载波；第二、第三载波等情况类似。
除非特殊说明，本申请实施例中所称的相同的数据包可以是相同的分组数据汇聚协议(packet data convergence protocol，PDCP)层数据包，也可以是相同的无线链路控制(radio link control，RLC)层数据包，也可以是相同的介质访问控制(media access control，MAC)层数据包。
例如，在重复传输PDCP层数据包的情况下，一个PDCP实体与两个RLC实体绑定。该终端设备将待发送的第一PDCP层数据包复制，得到第二PDCP层数据包。终端设备将该第一PDCP层数据包下发到该两个RLC实体中的一个RLC实体，将该第二PDCP层数据包下发到该两个RLC实体中的另一个RLC实体。该两个RLC实体分别对收到的PDCP层数据包进行处理并通过两个不同的载波将该第一PDCP层数据包和该第二PDCP层数据包发送至基站。该两个RLC实体对接收到的PDCP层数据包进行处理的过程与现有技术中不进行重复传输时RLC实体处理PDCP层数据包的方式相同在此就不必赘述。
终端设备用于进行重复传输功能RLC实体可以由基站通过RRC信令进行配置。例如，该基站可以配置该终端可以使用五个RLC实体进行重复传输，且五个RLC实体中的两个RLC实体处于激活状态，则该终端设备可以使用该两个RLC实体进行重复传输。
又如，在重复传输RLC层数据包的情况下，该终端设备会将待发送的第一RLC层数据包复制，得到第二RLC层数据包。终端设备将该第一RLC层数据包和该第二RLC层数据包发送至MAC实体。MAC实体会分别对两个RLC层数据包进行处理并通过两个不同的载波将两个RLC层数据包发送至该基站。MAC层实体对RLC层数据包进行处理的过程与中不进行重复传输时MAC实体处理RLC层数据包的方式相同在此就不必赘述。
又如，在重复传输MAC层数据包的情况下，该终端设备会将待传输的第一MAC层数据包复制，得到第二MAC层数据包，并通过两个不同的载波将两个MAC层数据包发送至该基站。
该终端设备可以进行PDCP层数据包重复传输、RLC层数据包重复传输，和MAC层数据包重复传输中的一种。该终端设备也可以进行PDCP层数据包重复传输、RLC层数据包重复传输，和MAC层数据包重复传输中的任意两种或者全部。
可以理解的是，本申请实施例中所称的重复传输数据包或者数据包重复传输功能中的重复传输(duplicated transmission)是指将一个数据包复制后得到两个或者两个以上的相同的数据包，分别采用不同载波传输这两个或两个以上的相同的数据包。本申请实施例中所称的重复传输并不是指自动重传请求等机制中的数据包重传(retransmission)。
可选的，在一些实施例中，该基站在配置了重复传输功能以及用于重复传输功能的逻辑信道以后，重复传输功能可以是始终处于激活状态。换句话说，该终端设备可以始终进行数据包重复传输。
可选的，在另一些实施例中，该基站在配置了重复传输功能以及用于重复传输功能的逻辑信道以后，重复传输功能是去激活的或者激活的状态。
可选的，在一些实施例中，该基站可以确定是否激活该重复传输功能，并指示该终端设备该重复传输功能是否被激活。
可选的，在一些实施例中，该基站可以根据信道质量、信道负载和信道传输误码率中 的一个或者多个确定是否激活该重复传输功能。该基站可以向该终端设备发送介质访问控制(media access control，MAC)控制元素(control element，CE)指示该终端设备激活或者去激活重复传输功能；
具体的，该MAC CE携带的指示信息可以包括逻辑信道标识(logical channel ID，LCID)域或者数据无线承载标识(data radio bear ID，DRB ID)域和状态指示域。在MAC CE用于激活重复传输功能的情况下，该MAC CE携带的指示信息中的逻辑信道标识域或者数据无线承载标识域用于指示所要激活的是哪几个逻辑信道或者哪个DRB的重复传输功能，状态指示域指示用于指示进行状态激活。
该终端设备收到该MAC CE以后，可以根据状态指示域确定是激活操作，根据逻辑信道标识域指示的逻辑信道标识，确定所要激活的是哪几个逻辑信道的重复传输功能，其中逻辑信道指示域只需要指示同一重复传输下几个逻辑信道中的一个即可。例如，逻辑信道1、逻辑信道2和逻辑信道3可以用于一个重复传输。逻辑信道4和逻辑信道5可以用于另一重复传输。该逻辑信道指示域只需要指示激活逻辑信道1即可。该终端设备在确定该逻辑信道指示域激活逻辑信道1的情况下，可以确定逻辑信道2和逻辑信道3同时被激活。当然，该逻辑信道指示域也可以指示同一重复传输下的全部逻辑信道。
或者该终端设备收到该MAC CE以后，可以根据状态指示域确定是激活操作，根据数据无线承载标识域指示的DRB标识，确定所要激活的是哪个DRB的重复传输功能。
在MAC CE用于去激活重复传输功能的情况下，该MAC CE携带的指示信息中的逻辑信道标识域或者数据无线承载标识域用于指示所要激活的是哪几个逻辑信道或者哪个DRB的重复传输功能，状态指示域指示进行状态去激活。
该终端设备收到MAC CE以后，可以根据状态指示域确定是去激活操作，根据逻辑信道标识域指示的逻辑信道标识，确定所要去激活的是哪几个逻辑信道的重复传输功能，其中逻辑信道指示域进一步指示所要去激活的某一个或者多个逻辑信道；
或者该终端设备收到该MAC CE以后，可以根据状态指示域确定是去激活操作，根据数据无线承载标识域指示的DRB标识，确定所要去激活的是哪个DRB的重复传输功能。
可选的，在重复传输功能去激活以后，UE使用其中一个逻辑信道传输数据，同时忽略事先配置好的逻辑信道与载波的绑定传输关系。所述绑定传输关系指基站配置的某个逻辑信道数据必须在某个载波上传输的关系。其中用于激活的MAC CE和去激活的MAC CE格式可以相同或者不同。可选的，在一些实施例中，状态指示域可以为1比特。例如，该MAC CE中的状态指示域值为0可以表示是该MAC CE是去激活MAC CE，用于去激活重复传输；该MAC CE中的状态指示域值为1可以表示该MAC CE是激活MAC CE，用于激活重复传输。逻辑信道标识域可以为6比特；数据无线承载标识域可以为5比特，另外MAC CE可以拥有N比特预留域，N为正整数，用于使得MAC CE大小为1字节；其中1字节等于8比特；MAC CE的大小可以总是整字节的倍数。如果状态指示域和逻辑系信道指示域或者状态指示域和无线承载标识域之和为N比特且N大于8，则预留域大小为16-N比特，MAC CE大小为2字节。如果状态指示域和逻辑系信道指示域或者状态指示域和无线承载标识域之和为N比特且N小于8，则预留域大小为8-N比特，MAC CE大小为1字节。
在载波聚合(carrier aggregation，CA)场景下，用于激活和去激活重复传输功能的 MAC CE由基站的MAC实体发送；在双连接(dual connectivity，DC)场景下，用于激活和去激活重复传输功能的MAC CE可以仅由主基站(master node，MN)下发，也可以仅由辅基站下发，也可以又主基站和辅基站分别下发。在终端设备收到一个或者多个基站下发的MAC CE以后，需要综合考虑一个或者多个基站下发的MAC CE中携带的指示信息，去判断此时某个DRB的重复传输功能是否应该是激活或者去激活状态；例如，假设该终端设备分别从主基站和辅基站收到两个MAC CE，如果两个基站下发的MAC CE均指示某个DRB的重复传输功能激活，则UE激活此DRB重复传输功能；如果两个基站下发的MAC CE均指示某个DRB的重复传输功能去激活，则UE去激活此DRB重复传输功能，并选择一条连接进行传输；如果两个基站下发的MAC CE，其中一个指示某个DRB重复传输功能激活，另一个指示同一个DRB重复传输功能去激活，则UE去激活重复传输功能并选择下发去激活MAC CE的那个基站进行数据传输。另外，可选的，UE在综合考虑两个基站下发的MAC CE的情况下，选择两个基站最新下发的MAC CE进行处理；可选的，可以为每一个MAC CE设置一个定时器，在收到一个MAC CE的时候启动，当定时器超时以后，UE在做决定的时候不再考虑此定时器对应的MAC CE。
可选的，在另一些实施例中，在步骤201之前，该终端设备可以接收该基站发送的重复传输指示信息，该重复传输指示信息用于指示该终端设备进行数据包重复传输。换句话说，图2所示的方法是在终端设备接收到该重复传输指示信息后执行的。该重复传输指示信息还可以用于指示重复传输数据包的类型，重复传输数据包的类型可以是PDCP层数据包、RLC层数据包和MAC层数据包中的至少一种。
可选的，在另一些实施例中，该终端设备可以根据事先配置的调节自行确定是否激活重复传输功能。具体地，在步骤201之前，该终端设备可以确定业务相关信息满足预设条件。换句话说，图2所示的方法是在终端设备确定业务相关信息满足预设条件的情况下执行的。该预设条件可以包括多种等级的预设条件。满足不同等级的预设条件进行重复传输的数据包的类型可以是不同改的。例如，在业务相关信息满足第一等级预设条件的情况下，终端设备可以进行PDCP层数据包重复传输；在业务相关信息满足第二等级预设条件的情况下，该终端设备可以进行RLC层数据包重复传输；在业务相关信息满足第三等级预设条件的情况下，该终端设备可以进行MAC层数据包重复传输。
该业务相关信息可以是与该终端设备向该基站发送的业务的质量相关的信息。例如，该业务相关信息可以是该终端设备向该基站发送的业务的服务质量(quality of service，QoS)需求。又如，该业务相关信息也可以是该终端设备向该基站发送的业务的可靠性需求。该业务相关信息也可以是与业务的传输相关的信息。例如，该业务相关信息可以是该第一载波和该第二载波的信道质量。又如，该业务相关信息也可以是该业务相关信息可以是待发送数据包的大小。该业务相关信息也可以是与业务的属性信息。例如，该业务相关信息可以是待发送数据包的大小。
该业务相关信息可以包括一个信息，也可以包括多个信息。例如，该业务相关信息可以是该终端设备向该基站发送的业务的QoS需求、该终端设备向该基站发送的业务的可靠性需求、该业务相关信息可以是待发送数据包的大小、该业务相关信息可以是待发送数据包的大小，和该第一载波和该第二载波的信道质量中的一个或者多个。

可选的，在一些实施例中，该终端设备可以通过显式指示的方式向该基站发送该RLF指示信息。例如，该终端设备可以相关基站发送RLF指示信令，该RLF指示信令中包括多个比特，该多个比特的取值为发生该RLF事件的载波所对应的载波号。
可选的，在另一些实施例中，该终端设备可以通过隐式指示的方式向该基站发送该RLF指示信息。例如，该终端设备可以向该基站发送与载波对应的一些信息来指示发生该RLF事件的载波。例如，若该数据包是PDCP层数据包或者RLC数据包，则该终端设备可以将于发生该RLF事件的载波所对应的逻辑信道指示给该基站。这样，该基站可以根据逻辑信道确定发生该RLF事件的载波。载波所对应的逻辑信道是指该载波用于发送该逻辑信道中的数据包。

可选的，在一些实施例中，该第一载波可以是第一主载波，该第二载波可以是第一辅载波。该基站在确定该第一载波发生RLF事件的情况下，可以向该终端设备发送重建指示信息，该重建指示信息用于指示该终端设备与基站进行RRC重建。该终端设备在接收到该重建指示信息的情况下，可以与该基站进行RRC重建。该基站在确定该第一载波未发生RLF事件且该第二载波发生RLF事件的情况下，可以向该终端设备发送该第二辅载波的配置信息。该终端设备在接收到该第二辅载波的配置信息的情况下，可以通过该第一载波和该第二辅载波向该基站发送相同的数据包。
进一步，在该基站为辅基站且该第一载波发生该RLF事件的情况下，该终端设备可以在该终端设备确定该第一载波发生该RLF事件时启动定时器。在该定时器超时且该终端设备未恢复使用该第一载波向该基站发送数据包的情况下，该终端设备可以向该基站发送该RLF指示信息。在该定时器超时前该终端设备恢复使用该第一载波向该基站发送数据包的情况下，该终端设备可以确定该第一载波未发生RLF事件，从而可以不向该基站发送RLF指示信息。
进一步，在一些实施例中，图2所示的方法还可以包括步骤203。
203，该终端设备在确定该第一载波和该第二载波中的至少一个发生RLF事件的情况下，可以向该基站发送以下信息中的至少一个：该RLF事件、多个载波的下行信道质量，和该终端设备确定的候选载波。

除非特殊说明，本申请实施例中所称的RLF事件可以是现有技术中的RLF事件，例如RLC层数据包的重传次数达到最大重传次数、由于失步信号引起链路失败、随机接入达到最大次数等，本申请实施例对此并不限定。
可选的，在一些实施例中，该终端设备可以在确定该终端设备通过第一载波发送的RLC层数据包的重传次数和该终端设备通过第二载波发送的RLC层数据包的重传次数同时达到最大重传次数的情况下，进行RRC重建。换句话说，只要该终端设备通过第一载波和第二载波中的一个载波的发送的RLC层数据包的重传次数未达到最大重传次数，该终端设备就不会进行RRC重建。
可选的，在一些实施例中，该终端设备可以在确定通过第一载波发送的第一RLC层数据包的重传次数和通过第二载波发送的该第一RLC层数据包的重传次数同时达到最大重传次数的情况下，进行RRC重建。换句话说，只有在第一载波的RLC层数据包的重传次数达和第二载波的RLC层数据包的重传次数达均达到最大次数且到达最大重传次数的RLC层数据包是同一个数据包的情况下，该终端设备才进行RRC重建。例如，假设最大重传次数为5。若第一RLC层数据包在第一载波上达到最大重传次数5次且该第一RLC层数据包在第二载波上只重传2次就传输成功，则该终端设备不会进行RRC重建。该终端设备只有在该第一RLC层数据包在该第一载波和该第二载波均达到最大重传次数的情况下，才进行RRC重建。
本申请实施例中所称的RRC重建的过程与现有技术中的RRC重建过程相同，在此就不必赘述。

所属领域的技术人员可以清楚地了解到，为描述的方便和简洁，上述描述的系统、装置和单元的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。
在本申请所提供的几个实施例中，应该理解到，所揭露的系统、装置和方法，可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。

本申请实施例还提供一种通信装置，该通信装置可以是终端也可以是电路。该通信装置可以用于执行上述方法实施例中由终端所执行的动作。
当该通信装置为终端时，图7示出了一种简化的终端的结构示意图。便于理解和图示方便，图7中，终端以手机作为例子。如图7所示，终端包括处理器、存储器、射频电路、天线以及输入输出装置。处理器主要用于对通信协议以及通信数据进行处理，以及对终端进行控制，执行软件程序，处理软件程序的数据等。存储器主要用于存储软件程序和数据。射频电路主要用于基带信号与射频信号的转换以及对射频信号的处理。天线主要用于收发电磁波形式的射频信号。输入输出装置，例如触摸屏、显示屏，键盘等主要用于接收用户输入的数据以及对用户输出数据。需要说明的是，有些种类的终端可以不具有输入输出装置。
当需要发送数据时，处理器对待发送的数据进行基带处理后，输出基带信号至射频电路，射频电路将基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发送。当有数据发送到终备时，射频电路通过天线接收到射频信号，将射频信号转换为基带信号，并将基带信号输出至处理器，处理器将基带信号转换为数据并对该数据进行处理。为便于说明，图7中仅示出了一个存储器和处理器。在实际的终端产品中，可以存在一个或多个处理器和一个或多个存储器。存储器也可以称为存储介质或者存储设备等。存储器可以是独立于处理器设置，也可以是与处理器集成在一起，本申请实施例对此不做限制。
在本申请实施例中，可以将具有收发功能的天线和射频电路视为终端的收发单元，将具有处理功能的处理器视为终端的处理单元。如图7所示，终端包括收发单元1110和处理单元1120。收发单元也可以称为收发器、收发机、收发装置等。处理单元也可以称为处理器，处理单板，处理模块、处理装置等。可选的，可以将收发单元1110中用于实现接收功能的器件视为接收单元，将收发单元1110中用于实现发送功能的器件视为发送单元，即收发单元1110包括接收单元和发送单元。收发单元有时也可以称为收发机、收发器、或收发电路等。接收单元有时也可以称为接收机、接收器、或接收电路等。发送单元有时也可以称为发射机、发射器或者发射电路等。
应理解，收发单元1110用于执行上述方法实施例中终端侧的发送操作和接收操作，处理单元1120用于执行上述方法实施例中终端上除了收发操作之外的其他操作。
例如，在一种实现方式中，收发单元1110用于执行前述实施例中终端侧的接收操作，和/或收发单元1110还用于执行本申请实施例中终端侧的其他收发步骤。处理单元1120用于执行前述实施例中终端侧的其他处理步骤。
