Description

数据发送方法及装置 技术领域
本公开涉及通信领域，尤其涉及数据发送方法及装置。
背景技术
为了支持终端之间的直接通信，引入了sidelink(直连链路)通信方式。Sidelink通信方式的协议栈参照图1所示，终端之间的接口为PC-5。Sidelink的传输通过MAC(Media Access Control，媒体访问控制)层的源标识和目标标识来实现寻址，在传输之前不需要建立连接。
目前，Sidelink通信方式包括两种数据传输方式：
第一种是通过网络侧动态调度终端进行直连通信时的发送资源；
第二种是终端在网络侧广播的资源池中选择进行直连通信时的发送资源。
如果采用第一种方式进行直连通信，终端需要向网络侧上报sidelink BSR(Buffer Status Report，缓存状态报告)，网络侧收到sidelink BSR后通过向终端发送DCI(Downlink Control Information，下行控制信息)，通过DCI指示终端可以使用的sidelink发送资源。如果终端采用第二种方式进行直连通信，则终端可以在网络侧配置的资源池中随机选择发送资源。
相关技术中，即使终端使用第一种直连通信方式，网络侧也会预先为终端配置exceptional resource pool(特殊资源池)，当终端无法从网络侧获得发送资源时，可以在特殊资源池中选择sidelink发送资源。
终端无法从网络侧获得发送资源的情况包括：终端检测到Uu接口发生无线链路失败，终端与网络侧建立RRC(Radio Resource Control，无线资源控制)连接之前，或者终端在进行切换的过程中。其中，Uu接口是终端与网络侧之间的接口。
在NR(New Radio，新空口)系统中，终端采用上述第一种直连通信 方式时，需要发送sidelink BSR到网络侧，然后网络侧才能为终端调度sidelink发送资源。但是，终端可能同时存在Uu BSR和sidelink BSR，即终端可能同时需要向网络侧上报与网络侧之间进行通信的Uu BSR和与其他终端进行直连通信的sidelink BSR。受上行发送资源的限制，终端可能只向网络侧发送Uu BSR，而sidelink BSR需要等待下次网络侧为终端调度了上行资源才能发送给网络侧。终端需要等待网络侧基于sidelink BSR为终端配置的发送资源，才能进行直连通信的数据发送。这会对sidelink通信的数据发送造成时延，无法保证sidelink服务质量。

本公开实施例中，如果在目标计时器计时结束之前，终端就接收到了基站发送的资源配置信息，那么终端可以直接将资源配置信息所指示的第一资源作为发送目标数据的目标资源，实现简便，可用性高。
本公开实施例中，可选地，如果在目标计时器计时结束之前，终端就接收到了基站发送的资源配置信息，那么相应地，终端可以控制目标计时器停止计时，在下次满足启动计时条件时，再重新启动目标计时器，避免终端接收到基站配置的第一资源后仍继续计时而导致发送直连链路数据的时延。
本公开实施例中，如果在目标计时器计时结束之前，终端仍未接收到 基站发送的资源配置信息，那么终端可以直接在预设资源池中确定第二资源。其中，预设资源池是所述基站预先分配给所述终端的、在所述终端无法从所述基站获得资源调度时所使用的直连链路资源池。减少了直连链路数据发送的时延，提高了直连链路的服务质量。
本公开实施例中，终端可以在确定是否满足启动计时条件之前，根据基站侧发送的时长配置信息，分别确定自身的每个直连链路逻辑信道各自对应的计时器的计时时长，可用性高。
本公开实施例中，基站可以基于终端上报的直连链路缓存状态报告，为所述终端配置第一资源，并通过资源配置信息发送给终端。终端可以基于目标计时器计时结束之前是否接收到基站发送的资源配置信息，确定目标资源，从而通过目标资源发送目标直连链路逻辑信道上的目标数据。通过上述过程，可以为终端快速确定进行直连通信的目标资源，通过目标资源发送目标数据，减少直连链路数据发送的时延，提高直连链路的服务质量。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
在本公开使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。 还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
相关技术中，参照图2所示，基站可发送SIB(System Information Block，系统信息块)给终端，终端通过sidelink UE Information(直连链路终端消息)向网络侧发送sidelink辅助信息，该辅助信息中可以包括终端标识以及终端是否对sidelink发送和/或接收感兴趣等。
基站接收到sidelink UE Information之后，如果终端对sidelink发送和/或接收感兴趣，那么可以由基站动态调度终端sidelink发送资源。终端在进行直连通信时所使用的直连链路资源复用终端和网络侧通过Uu接口进行上行通信使用的无线资源。因此，有可能出现终端同时存在Uu BSR和sidelink BSR。
终端可能只向网络侧发送Uu BSR，而sidelink BSR需要等待下次网络侧为终端调度了上行资源才能发送给网络侧。终端需要等待网络侧基于sidelink BSR为终端配置的发送资源，才能进行直连通信的数据发送。这会对sidelink通信的数据发送造成时延，无法保证sidelink服务质量。
而在NR系统中，Sidelink上支持增强的V2X(vehicle to everything，车联网)的业务，Uu接口支持URLLC(Ultra Reliable Low Latency Communication，超可靠低时延通信)业务，这两种业务都需要很低的时延和很高的可靠性。为了减少直连链路数据发送的时延，提高直连链路的服务质量，本公开实施例提供了一种数据发送方法和装置。
下面先从终端侧介绍一下本公开实施例提供的数据发送方法。
参照图3所示，图3是根据一实施例示出的一种数据发送方法流程图，可以用于终端，可选地，终端可以是用户的手持设备，例如手机、ipad等，或者终端还可以是直连通信智能设备，例如车载设备、智能电表等，该方法可以包括以下步骤：
在步骤101中，在启动目标直连链路逻辑信道对应的目标计时器之后，基于所述目标计时器计时结束之前是否接收到基站发送的资源配置信息，确定目标资源。
其中，所述资源配置信息是所述基站为所述终端配置的第一资源的资源信息，所述第一资源是用于发送所述目标直连链路逻辑信道上待发送的目标数据的资源。
在步骤102中，通过所述目标资源发送所述目标直连链路逻辑信道上的所述目标数据。
上述实施例中，终端可以基于目标计时器计时结束之前是否接收到基站发送的资源配置信息，确定目标资源，从而通过目标资源发送目标直连链路逻辑信道上的目标数据。通过上述过程，终端可以快速确定进行直连通信的目标资源，通过目标资源发送目标数据，减少直连链路数据发送的时延，提高直连链路的服务质量。
在一实施例中，参照图4所示，图4是根据图3所示的实施例示出的另一种数据发送方法流程图，所述方法还包括：
在步骤100-1中，确定所述终端的任一条直连链路逻辑信道对应的计时器是否满足预设的启动计时条件。
在步骤100-2中，在所述目标直连链路逻辑信道对应的所述目标计时器满足所述启动计时条件时，启动所述目标计时器。
上述实施例中，终端可以先确定任一条直连链路逻辑信道对应的计时器是否满足预设的启动计时条件，在目标直连链路逻辑信道对应的目标计时器满足启动计时条件时，启动目标计时器，以便基于目标计时器计时结束之前是否接收到基站发送的资源配置信息，来确定目标资源，减少直连 链路数据发送的时延，可用性高。
在一实施例中，启动计时条件包括以下任一项：所述目标直连链路逻辑信道存在需要发送给所述基站的直连链路缓存状态报告；接收到高层发送给所述目标直连链路逻辑信道的所述目标数据。
本公开实施例中，终端可以在终端的任一个直连链路逻辑信道存在需要上报给基站的直连链路缓存状态报告时，确定该直连链路逻辑信道为目标直连链路逻辑信道，且目标直连链路逻辑信道对应的目标计时器满足预设的启动计时条件。
或者终端可以在某个直连链路逻辑信道接收到终端的高层，例如应用层、RRC层等发送的目标数据时，确定该直连链路逻辑信道为目标直连链路逻辑信道，且目标直连链路逻辑信道对应的目标计时器满足预设的启动计时条件。
上述实施例中，启动计时条件可以包括终端的目标直连链路逻辑信道存在需要发送给基站侧的直连链路缓存状态报告，或者目标直连链路逻辑信道接收到终端高层发送的目标数据。终端可以在满足任意一个条件时，启动目标直连链路逻辑信道对应的目标计时器，从而基于是否接收到基站发送的资源配置信息，确定目标资源，减少直连链路数据发送的时延，提高直连链路的服务质量。
在一实施例中，步骤101可以包括：
在步骤101-1中，在所述目标计时器计时结束之前，如果接收到所述资源配置信息，则将所述资源配置信息所指示的所述第一资源作为所述目标资源。
例如，目标计时器的计时时长为5毫秒，终端在5毫秒内接收到了基站发送的资源配置信息，那么终端直接将资源配置信息所指示的第一资源作为目标资源。后续通过目标资源发送目标直连链路逻辑信道上的目标数据。
上述实施例中，如果在目标计时器计时结束之前，终端就接收到了基 站发送的资源配置信息，那么终端可以直接将资源配置信息所指示的第一资源作为发送目标数据的目标资源，实现简便，可用性高。
在一实施例中，参照图5所示，图5是根据图3所示的实施例示出的另一种数据发送方法流程图，该方法还可以包括：
在步骤103中，在接收到所述资源配置信息之后，控制所述目标计时器停止计时。
例如，目标计时器的计时时长为5毫秒，终端在第4毫秒接收到了基站发送的资源配置信息，此时终端可以控制目标计时器停止计时。终端就可以尽快通过第一资源将目标数据发送出去，避免终端接收到基站配置的第一资源后仍继续计时而导致发送直连链路数据的时延。
在一实施例中，参照图6所示，图6是根据图3所示的实施例示出的另一种数据发送方法流程图，步骤101可以包括：
在步骤101-2中，在所述目标计时器计时结束之前，如果未接收到所述资源配置信息，则在预设资源池中确定第二资源。
本公开实施例中，基站已经预先为终端配置了直连通信的预设资源池，如果终端无法从基站获得资源调度可以使用该预设资源池中的资源进行直连链路通信。可选地，预设资源池可以是exceptional resource pool。
在目标计时器计时结束之前，如果终端一直未接收到所述资源配置信息，那么终端可以直接在预设资源池中确定第二资源。
在步骤101-3中，将所述第二资源作为所述目标资源。
本步骤中，终端可以直接将从预设资源池中确定的第二资源作为发送目标数据的目标资源。
上述实施例中，如果在目标计时器计时结束之前，终端仍未接收到基站发送的资源配置信息，那么终端可以直接在预设资源池中确定第二资源。其中，预设资源池是所述基站预先分配给所述终端的、在所述终端无法从所述基站获得资源调度时所使用的直连链路资源池。减少了直连链路数据发送的时延，提高了直连链路的服务质量。
在一实施例中，参照图7所示，图7是根据图3所示的实施例示出的另一种数据发送方法流程图，在执行步骤101之前，该方法还可以包括：
在步骤100-3中，根据基站发送的时长配置信息，分别确定所述终端的每个所述直连链路逻辑信道各自对应的计时器的计时时长。
本公开实施例中，可以由基站为终端配置终端的每个直连链路逻辑信道各自对应的所述计时器的所述计时时长，并通过时长配置信息告知终端。终端基于接收到的时长配置信息，分别确定出每个直连链路逻辑信道各自对应的计时器的计时时长。
例如，终端根据基站的配置信息，确定直连链路逻辑信道1对应的计时器1的计时时长为5毫秒，直连链路逻辑信道2对应的计时器2的计时时长为6毫秒。
在本公开实施例中，基站为终端配置的所述直连链路逻辑信道各自对应的计时器的计时时长可以相同或不同，本公开对此不作限定。
上述实施例中，终端可以在确定是否满足启动计时条件之前，根据基站侧发送的时长配置信息，分别确定自身的每个直连链路逻辑信道各自对应的计时器的计时时长，可用性高。
下面再从基站侧介绍本公开实施例提供的数据发送方法。
参照图8所示，图8是根据一实施例示出的另一种数据发送方法流程图，可以用于基站，该方法可以包括以下步骤：
在步骤201中，基于终端上报的直连链路缓存状态报告，为所述终端配置第一资源。
本公开实施例中，如果基站接收到终端上报的直连链路缓存状态报告，基站就基于直连链路缓存状态报告为终端配置第一资源。
在步骤202中，发送资源配置信息给所述终端。
其中，所述资源配置信息包括所述第一资源的资源信息。
基站通过资源配置信息将第一资源的资源信息告知终端，终端如果在目标计时器计时结束之前接收到该资源配置信息，那么终端可以将第一资 源作为目标资源，通过目标资源发送目标数据。
当然，如果终端在目标计时器计时结束之前未接收到该资源配置信息，那么终端可以在基站预先配置给终端的预设资源池中确定第二资源，将第二资源作为目标资源，同样通过目标资源发送目标数据。
上述实施例中，基站可以基于终端上报的直连链路缓存状态报告，为所述终端配置第一资源，并通过资源配置信息发送给终端。终端可以基于目标计时器计时结束之前是否接收到基站发送的资源配置信息，确定目标资源，从而通过目标资源发送目标直连链路逻辑信道上的目标数据。通过上述过程，可以为终端快速确定进行直连通信的目标资源，通过目标资源发送目标数据，减少直连链路数据发送的时延，提高直连链路的服务质量。
在一实施例中，参照图9所示，图9是根据图8所示的实施例示出的另一种数据发送方法流程图，在执行步骤201之前，该方法还可以包括：
在步骤200-1中，为所述终端配置预设资源池。
其中，所述预设资源池是所述基站分配给所述终端的、在所述终端无法从所述基站获得资源调度时所使用的直连链路资源池。
本公开实施例中，终端除了无法从基站获得资源调度时使用预设资源池中的资源进行直连通信之外，还可以在目标计时器计时结束之前如果未接收到基站发送的资源配置信息，使用预设资源池中的第二资源作为发送目标数据的目标资源，从而减少终端等待基站配置的第一资源才能发送目标数据所造成的时延。
在一实施例中，参照图10所示，图10是根据图9所示的实施例示出的另一种数据发送方法流程图，在执行步骤201之前，该方法还可以包括：
在步骤200-2中，为终端配置所述终端的每个直连链路逻辑信道各自对应的计时器的计时时长。
本步骤中，基站可以基于终端不同的直连链路逻辑信道各自执行的业务、信道质量等，为不同的直连链路逻辑信道配置各自对应的计时器的计时时长。当然，基站也可以基于其他信息为不同的直连链路逻辑信道配置 各自对应的计时器的计时时长，且计时时长可以相同或不同，本公开对此不作限定。
例如，如果终端直连链路逻辑信道1对应的业务需要低时延，则基站可以为直连链路逻辑信道1对应的计时器1配置较短的计时时长。如果终端直连链路逻辑信道2对应的信道质量较好，且直连链路逻辑信道2对应的业务对时延要求不高，但是数据量比较大，则基站可以为直连链路逻辑信道1对应的计时器1配置较长的计时时长。
在步骤200-3中，发送时长配置信息给所述终端。
本步骤中，基站可以通过时长配置信息将为终端配置的每个所述直连链路逻辑信道各自对应的所述计时器的所述计时时长告知终端，由终端确定每个所述直连链路逻辑信道各自对应的所述计时器的所述计时时长。
上述实施例中，可以由基站为终端配置每个所述直连链路逻辑信道各自对应的所述计时器的所述计时时长，实现简便，可用性高。
在一实施例中，参照图11所示，图11是根据一实施例示出的另一种数据发送方法流程图，该方法可以包括以下步骤：
在步骤301中，基站为终端配置预设资源池。
其中，所述预设资源池是所述基站分配给所述终端的、在所述终端无法从所述基站获得资源调度时所使用的直连链路资源池。可选地，预设资源池可以是exceptional resource pool。在步骤302中，基站为终端配置所述终端的每个直连链路逻辑信道各自对应的计时器的计时时长。
在步骤303中，基站发送时长配置信息给所述终端。
其中，所述时长配置信息中包括所述终端的每个所述直连链路逻辑信道各自对应的所述计时器的所述计时时长。
在步骤304中，终端确定所述终端的任一条直连链路逻辑信道对应的计时器是否满足预设的启动计时条件。
其中，所述启动计时条件包括以下任一项：所述目标直连链路逻辑信道存在需要发送给所述基站的直连链路缓存状态报告；接收到高层发送给 所述目标直连链路逻辑信道的所述目标数据。
在步骤305中，终端在目标直连链路逻辑信道对应的目标计时器满足所述启动计时条件时，启动所述目标计时器。
在步骤306中，基站基于终端上报的直连链路缓存状态报告，为所述终端配置第一资源。
其中，所述第一资源是所述终端用于发送目标直连链路逻辑信道上待发送的目标数据的资源。
在步骤307中，基站发送资源配置信息给所述终端。
其中，所述资源配置信息包括所述第一资源的资源信息。
在步骤308中，终端在所述目标计时器计时结束之前，如果接收到所述资源配置信息，则将所述资源配置信息所指示的所述第一资源作为所述目标资源。
在步骤309中，终端在所述目标计时器计时结束之前，如果未接收到所述资源配置信息，则在预设资源池中确定第二资源。
在步骤310中，终端将所述第二资源作为所述目标资源。
在步骤311中，终端通过所述目标资源发送所述目标直连链路逻辑信道上的所述目标数据。
上述实施例中，终端如果在目标计时器计时结束之前，接收到基站发送的资源配置信息，那么就将资源配置信息指示的第一信息作为目标资源，如果在目标计时器计时结束之前，未接收到基站发送的资源配置信息，那么终端将预设资源池中的第二资源作为目标资源。通过目标资源发送目标直连链路逻辑信道上的目标数据。减少了直连链路数据发送的时延，提高了直连链路的服务质量。
下面对本公开实施例提供的数据发送方法进一步举例说明如下。
例如，终端包括直连链路逻辑信道1、2和3，基站为直连链路逻辑信道分别配置了计时器的计时时长，分别为4毫秒、5毫秒和6毫秒。
其中，直连链路逻辑信道1存在需要发送给所述基站的直连链路缓存 状态报告，那么终端启动直连链路逻辑信道1对应的计时器1，计时时长为4毫秒。
终端在4毫秒内接收到基站发送的资源配置信息，则终端通过资源配置信息所指示的第一资源发送直连链路逻辑信道1上的目标数据，且控制直连链路逻辑信道1对应的计时器停止计时。
再例如，终端包括直连链路逻辑信道1、2和3，基站为直连链路逻辑信道分别配置了计时器的计时时长，分别为4毫秒、5毫秒和6毫秒。
其中，直连链路逻辑信道1存在需要发送给所述基站的直连链路缓存状态报告，那么终端启动直连链路逻辑信道1对应的计时器1，计时时长为4毫秒。
终端在4毫秒内未接收到基站发送的资源配置信息，则终端将通过预设资源池中的第二资源发送直连链路逻辑信道1上的目标数据。
再例如，终端包括直连链路逻辑信道1、2和3，基站为直连链路逻辑信道分别配置了计时器的计时时长，分别为4毫秒、5毫秒和6毫秒。
其中，直连链路逻辑信道1接收到终端的高层发送的目标数据，那么终端启动直连链路逻辑信道1对应的计时器1，计时时长为4毫秒。
终端在4毫秒内接收到基站发送的资源配置信息，则终端通过资源配置信息所指示的第一资源发送直连链路逻辑信道1上的目标数据，且控制直连链路逻辑信道1对应的计时器停止计时。
再例如，终端包括直连链路逻辑信道1、2和3，基站为直连链路逻辑信道分别配置了计时器的计时时长，分别为4毫秒、5毫秒和6毫秒。
其中，直连链路逻辑信道1接收到终端的高层发送的目标数据，那么终端启动直连链路逻辑信道1对应的计时器1，计时时长为4毫秒。
终端在4毫秒内未接收到基站发送的资源配置信息，则终端将通过预设资源池中的第二资源发送直连链路逻辑信道1上的目标数据。
