本申请主张在2018年9月27日在中国提交的中国专利申请号No.201811133798.1的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种缓存报告传输方法、终端及调度设备。
背景技术
长期演进(Long Term Evolution，LTE)系统从第12个发布版本开始支持旁链路(sidelink，或译为副链路，侧链路，边链路等)，用于终端用户设备(User Equipment，UE)之间不通过网络设备进行直接数据传输。
UE通过物理旁链路控制信道(Physical Sidelink Control Channel，PSCCH)发送旁链路控制信息(Sidelink Control Information，SCI)，调度物理旁链路共享信道(Physical Sidelink Shared Channel，PSSCH)的传输以发送数据。该传输是以广播形式进行的，接收端并不向发送端反馈接收是否成功。
LTE sidelink设计支持两种资源分配模式，分别是调度资源分配(Scheduled resource allocation)模式与自主资源选择(autonomous resource selection)模式。前者由网络侧设备控制并为每个UE分配资源，后者由UE自主选择资源。
从第15个发布版本开始，LTE支持sidelink载波汇聚(Carrier Aggregation，CA)。LTE sidelink的CA与Uu接口(即downlink与uplink)不同，没有主载波(Primary component carrier，PCC)与辅载波(Secondary component carrier，SCC)之分。自主资源选择模式的UE在每个CC上独立进行资源感知(sensing)与资源预留。
第五代移动通信技术(5G NR)系统可用于LTE所不支持的6GHz以上工作频段，支持更大的工作带宽以及多波束传输。但目前NR系统中，只支 持基站与终端间的接口，尚不支持终端之间直接通信的Sidelink接口。

附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对本公开实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
如图1所示，本公开实施例的缓存报告传输方法，应用于终端，包括：
步骤101，发送缓存报告到调度设备；其中，所述缓存报告用于指示以下目标信息中的至少一项：
待传输的旁链路sidelink数据的数据大小和对应的信道；
待传输的sidelink数据的传输类型；
待传输的sidelink数据的传输对象；
待传输的sidelink数据的波束信息；
以及，待传输的sidelink数据的缓存类型。
通过上述步骤，终端能够发送缓存报告到调度设备，且该缓存报告可用于指示：待传输的sidelink数据的数据大小和对应的信道；待传输的sidelink数据的传输类型；待传输的sidelink数据的传输对象；待传输的sidelink数据的波束信息；以及，待传输的sidelink数据的缓存类型中的至少一项信息，从而使得调度设备了解到该终端sidelink数据传输的相关信息，能够为该终端完成更有效的sidelink数据传输配置。
可选地，步骤101包括：
在存在sidelink数据待传输的情况下，发送所述缓存报告到调度设备。
如此，终端会在需要传输sidelink数据的情况下，及时发送该缓存报告到调度设备，以保证sidelink数据传输的及时性。
应该知道的是，在该实施例中，对应待传输的sidelink数据的信道(例如，逻辑信道)，可以是单信道，也可以是多个信道(即信道组)；待传输的sidelink数据的传输类型具体为：单播传输、组播(多播)传输以及广播传输；待传输的sidelink数据的传输对象，即与该终端进行sidelink数据传输的对端设备，如终端用户设备UE；待传输的sidelink数据的波束信息包括但不限于该终端发送待传输的sidelink数据到传输对象使用的波束(扫描波束、一个或多个特定波束)标识、波束发送方式，该波束标识可以是波束ID，参考信号/信道标示index，传输配置指示TCI等；待传输的sidelink数据的缓存类型将用于指示待传输的sidelink数据是在LTE还是NR缓存，以便调度设备可以正确调度终端的传输，缓存类型具体为：LTE sidelink或者NR sidelink。
这里，该调度设备可以是网络设备如基站，也可以是能够调度其它UE的UE。
其中，所述缓存报告直接指示所述目标信息或者间接指示所述目标信息。
这里，终端由缓存报告BSR上报上述目标信息到调度设备，BSR既可以直接指示，也可以间接指示。
直接指示的方式，终端建立sidelink单播或组播后，可以不需要报告给调度设备，直接在BSR通知相关信息。例如，缓存报告直接指示待传输的sidelink数据的传输对象，在单播传输的情况下，该缓存报告会携带该传输对象的身份标识ID，该身份标识具体可以为数据链路层ID、物理层ID、应用层ID或 者互联网协议IP地址等等；在组播传输的情况下，该缓存报告会携带组播传输对象的组ID，此时，组播传输对象的各个终端都归属于该组ID中。又或者，缓存报告携带传输类型信息，如广播传输或单播传输，来直接指示待传输的sidelink数据的传输类型。
间接指示的方式，BSR因携带的信息比特数可以远小于直接指示的信息，可以节省BSR的开销。可选地，该实施例中，所述缓存报告间接指示所述目标信息包括：
基于与混合自动重传请求HARQ实体的关联关系，指示所述目标信息；或者
基于与预设标识的关联关系，指示所述目标信息；或者
基于与资源单元的关联关系，指示所述目标信息；或者
基于与波束的关联关系，指示所述目标信息；或者
基于与信道的关联关系，指示所述目标信息。
如此，该实施例中，考虑到HARQ实体的构建，会基于与HARQ实体的关联关系，来指示目标信息。例如，每个单播UE连接建立一个HARQ实体，每个组播的组建立一个HARQ实体，广播对应一个HARQ实体，BSR就可以报告关联的HARQ实体以指示对应的传输对象。当然，实体的构建可以是预定义实现的。
又或者，该实施例中，对于已建立的预设标识与信息的关联关系，BSR会通过携带特定的预设标识来指示对应的目标信息。例如，待传输的sidelink数据的传输对象(单播UE的ID或组播的组ID)关联一个下标或标识索引，广播对应一个下标或标识索引(可以是预定义的下标，例如0)，BSR就可以报告下标或标识索引以指示对应的传输对象。当然，该预设标识不限于预定义的标识，还可以是在运行时配置的。
此外，该实施例中，BSR还可通过携带资源单元(如载波，频点，资源池，带宽部分BWP等)，来指示对应的目标信息。例如，待传输的sidelink数据的传输对象对应或分配了资源单元用于收发数据，BSR就可以报告该资源单元的信息以指示对应的传输对象。
又或者，该实施例中，对应不同类型数据设置不同的发送方式，如广播 数据使用(全部)波束扫描发送，单播数据使用单一波束发送，组播数据使用一个或多个波束发送，而且，不同的单播传输对象，可能使用不同的波束发射(如对应不同的方向)，BSR则会通过携带波束信息(如波束发送方式和/或波束标识等)，来指示对应的目标信息。例如，BSR可以报告波束发送方式和/或波束标识以指示其对应的传输对象。
另外，该实施例中，对应不同类型数据设置不同的信道或信道组，如广播、单播、组播数据对应不同的信道或信道组，而且不同的单播传输对象，可能使用不同的信道或信道组，BSR则会通过携带信道信息(如信道ID或index，信道组ID或index)，来指示对应的目标信息。例如，BSR可以报告信道ID或index以指示其对应的传输对象。
然而，由上述内容可知，缓存报告间接指示目标信息的方式，要明确该缓存报告指示的内容，需了解缓存报告报告内容与具体指示目标信息间的关联。因此，如图2所示，在步骤101之前，还包括：
步骤102，发送sidelink调度信息至所述调度设备。
可选地，所述sidelink调度信息包括以下信息中的至少一项：
自身的最大处理能力；
传输对象；
传输对象对应的传输类型；
以及，传输对象对应的传输波束信息。
这里，因该sidelink调度信息包括了自身的最大处理能力；传输对象；传输对象对应的传输类型；以及，传输对象对应的传输波束信息中的至少一项，调度设备在接收到缓存报告，且该缓存报告间接指示目标信息的情况下，就能够结合sidelink调度信息进一步明确缓存报告间接指示的具体目标信息。当然，该sidelink调度信息中各项信息的具体表述格式是与缓存报告间接指示的具体内容对应的。例如，系统设置各传输类型对应预设标识：单播传输为A1、组播传输为A2、广播传输为A3，在当前终端与另一终端(终端ID为B1)建立单播连接后，当前终端先发送sidelink调度信息(包括建立单播连接的另一终端的终端ID、单播传输的预设标识)到调度设备，如此，在缓存报告携带预设标识A1上报调度设备，调度设备结合sidelink调度信息，既可知发送 缓存报告的终端是与终端ID为B1的终端进行单播传输。
其中，终端自身的最大处理能力具体可以为该终端所支持的同时接收的波束方向，或者频率范围等，以便调度设备进行适用该终端能力的传输配置。
可选地，在该实施例中，所述缓存报告包括一个或多个格式；
每个格式的缓存报告指示不同的所述目标信息，或者，每个格式的缓存报告通过不同的方式指示所述目标信息。
例如，广播、组播、单播使用不同的BSR格式；或者，广播等传输类型使用的BSR直接指示目标信息，而单播等传输类型的BSR间接指示目标信息，等等。
还应该知道的是，该实施例中，BSR可以同时指示一个或多个不同的传输类型，也可以同时指示一个或多个不同的传输对象的数据，在此不再赘述。
调度设备根据缓存报告指示目标信息进行传输配置，既可以分配特定的资源池或多个时频资源，用于上报BSR的终端通过波束扫描发送广播数据或组播数据；又可以分配特定的资源池、特定时频资源、波束标识和发送功率中的至少一项，指示UE通过特定的资源发送或接收单播数据或组播数据。并且，该调度设备在配置过程中，会结合终端自身的最大处理能力，配置的波束和/或资源不能超出终端自身的最大处理能力。例如调度设备通过终端自身的最大处理能力可知终端只支持一个接收波束，则该调度设备将不会调度该终端同时从两个方向接收数据。调度设备不限于通过接收sidelink调度信息获知终端的最大处理能力，也可以由其它方式获得。
下面结合具体实施例说明本公开实施例的缓存报告传输方法的应用：

c.基站还可以把该时频资源指示给UE3、UE4，并指示它们使用指向UE1的波束接收来自UE1的数据。
场景四：(如图7所示，UE1/2/3都在基站的小区内，按调度资源分配模式工作。UE1与UE2、UE3建立了单播连接)
1.UE1向基站上报自身只支持一个接收波束。
2.UE1有数据发送给UE2时，向基站上报BSR，其中指示了单播数据发送的接收端UE2的UE ID以及待发送数据大小。
3.基站收到UE2与UE3的BSR，得知UE2与UE3要给UE1发送单播数据。且基站还可以根据BSR的内容，知道UE1与UE2、UE3配对的波束信息。基站分配可用于单播的时频资源给UE2、UE3，调度UE2、UE3使用指向UE1的波束发送数据。但基站确保UE2、UE3不会同时向UE1传输，这样UE1可以使用单个接收波束分别接收来自UE2、UE3的不同数据。
综上所述，本公开实施例的缓存报告传输方法，能够发送缓存报告到调度设备，且该缓存报告可用于指示：待传输的sidelink数据的数据大小和对应的信道；待传输的sidelink数据的传输类型；待传输的sidelink数据的传输对象；待传输的sidelink数据的波束信息；以及，待传输的sidelink数据的缓存类型中的至少一项信息，从而使得调度设备了解到该终端sidelink数据传输的相关信息，能够为该终端完成更有效的sidelink数据传输配置。
如图3所示，本公开实施例的缓存报告传输方法，应用于调度设备，包括：
步骤301，接收终端发送的缓存报告；其中，
所述缓存报告用于指示以下目标信息中的至少一项：
待传输的sidelink数据的数据大小和对应的信道；
待传输的sidelink数据的传输类型；
待传输的sidelink数据的传输对象；
待传输的sidelink数据的波束信息；
以及，待传输的sidelink数据的缓存类型。
通过上述步骤，调度设备接收到终端发送的缓存报告且该缓存报告可用于指示：待传输的sidelink数据的数据大小和对应的信道；待传输的sidelink数据的传输类型；待传输的sidelink数据的传输对象；待传输的sidelink数据的波束信息；以及，待传输的sidelink数据的缓存类型中的至少一项信息，从而能够由该信息为终端完成更有效的sidelink数据传输配置。
可选地，所述缓存报告直接指示所述目标信息或者间接指示所述目标信息。
可选地，所述缓存报告间接指示所述目标信息包括：

基于与预设标识的关联关系，指示所述目标信息；或者
基于与资源单元的关联关系，指示所述目标信息；或者
基于与波束的关联关系，指示所述目标信息；或者
基于与信道的关联关系，指示所述目标信息。
可选地，在所述接收终端发送的缓存报告之前，还包括：
接收所述调度设备发送的sidelink调度信息。
可选地，所述sidelink调度信息包括以下信息中的至少一项：

发送所述缓存报告对应的传输配置信息至所述终端；其中，
所述传输配置信息用于：指示终端通过波束扫描发送广播数据或组播数 据；或者，指示终端通过配置的资源发送或接收单播数据或组播数据。
可选地，所述传输配置信息中配置的波束和/或资源不能超出终端自身的最大处理能力。
在该实施例中，调度设备根据缓存报告指示目标信息进行对应的传输配置，既可以分配特定的资源池或多个时频资源，用于上报BSR的终端通过波束扫描发送广播数据或组播数据；又可以分配特定的资源池、特定时频资源、波束标识和发送功率中的至少一项，指示UE通过特定的资源发送或接收单播数据或组播数据。并且，该调度设备在配置过程中，会结合终端自身的最大处理能力，配置的波束和/或资源不能超出终端自身的最大处理能力。例如调度设备通过终端自身的最大处理能力可知终端只支持一个接收波束，则该调度设备将不会调度该终端同时从两个方向接收数据。调度设备不限于通过接收sidelink调度信息获知终端的最大处理能力，也可以由其它方式获得。
需要说明的是，该方法是与上述应用于终端的缓存报告传输方法配合，实现有效的sidelink数据传输配置的，上述应用于终端的缓存报告传输方法的实施例的实现方式适用于该方法，也能达到相同的技术效果。
