一种SR/BSR触发方法和装置

技术领域
本公开涉及通信技术领域，尤其涉及一种SR(Scheduling Request，调度请求)/BSR(Buffer Status Report，缓存状态报告)触发方法和装置。
背景技术
1)SR和/或BSR机制介绍
LTE(Long Term Evolution，长期演进)/LTE-A(LTE-Advanced的简称,是LTE技术的后续演进)系统是一个基于调度的通信系统，即：如果UE的发送缓存中有数据需要发送，那么UE需要先给基站发送一个BSR，告诉基站UE(User Equipment,用户设备)的当前的发送缓存中需要发送的数据信息。基站在收到UE发送的BSR后，根据UE要发送的数据多少以及业务类型来为UE分配相应的上行共享信道(UL-SCH，Uplink Shared Channel)资源，并通知UE在分配的UL-SCH资源上发送数据。
UE向基站发送BSR也需要使用上行共享信道(UL-SCH)资源，如果有BSR需要上报，但此时没有上行共享信道资源，那么就会触发SR(调度请求：Scheduling Request)，请求基站为需要发送的BSR分配上行共享信道资源。
触发SR后，发送SR的方式有两种，即：通过专用调度请求资源发送SR(D-SR)和通过随机接入过程来进行SR(RA-SR)。
专用SR(D-SR)：当UE和基站处于同步状态下不一定有发送D-SR的资源，处于非同步状态下一定没有D-SR资源。D-SR由RRC(Radio Resource Control，无线资源控制)分配，由PUCCH(Physical Uplink Control CHannel，物理上行链路控制信道)承载。利用D-SR资源来发送SR。
随机接入SR(RA-SR)：利用随机接入过程来发送SR。
SR发送的基本原则是：只要有D-SR资源，就不使用RA-SR。
SR的发送时刻：在收到基站为UE分配的用于发送数据的上行共享信道资源之前，可以在能够发送SR的资源上重复发送SR。
2)Numerology和/或TTI长度
Numerology是3GPP RAN1的一个专业术语，可以翻译为基带参数。不同numerology之间的主要区别是不同numerology支持的子载波间隔不同。比如子载波间隔15KHz和60KHz对应两个不同的numerology和/或TTI长度。比如5G NR(New Radio，新空口)系统支持的子载波间隔至少包括：15KHz，60KHz，这两个不同子载波间隔对应的numerology就是两个独立的numerology。一般而言，高速移动的终端使用的numerology和低速移动的终端使用的numerology不同；高频和低频使用的numerology也不相同。不同numerology的使用除了和移动速度以及频率相关外，业界还有一种理解就是不同业务可以使用的numerology也可能不同，比如URLLC(Ultra Reliable&Low Latency Communication，低时延、高可靠通信)和eMBB(Enhance Mobile Broadband，增强型移动宽带)使用的numerology可能不同。
3)TTI长度
TTI即传输时间间隔(Transmission Time interval)。传统的LTE系统中，TTI长度为1ms。从LTE R14开始，为了支持时延缩减，引入了不同TTI长度，比如1个OFDM(Orthogonal Frequency Division Multiplexing，正交频分复用)符号长度。
不同TTI长度在5G系统中得到沿用并可以应用于每个numerology上，即5G NR中不同numerology可以使用不同TTI长度，也可以使用相同TTI长度，并且任何一个时刻某个numerology上针对不同终端使用的TTI长度可以是动态变化的。TTI长度的选择主要和业务时延相关，比如对于URLLC业务因为其支持的时延要求比较高，所以可能会选择长度较短的TTI长度，比如1个OFDM符号的TTI长度。
对于LTE系统，终端聚合的所有小区都使用相同的numerology和/或TTI长度。但是5G系统与LTE系统不同，其对numerology和/或TTI长度支持更 加灵活。比如终端聚合的一个小区内可以支持多个numerology和/或TTI长度，终端聚合的不同聚合小区支持的numerology和/或TTI长度可以相同，也可以不同。
5G系统支持多种numerology和/或TTI长度并存，并且终端一个承载/逻辑信道可以使用的numerology和/或TTI长度是网络侧配置给终端的，这种情况下需要解决终端某个承载/逻辑信道有上行数据传输需求，但是终端在其可以使用的numerology和/或TTI长度上行失步情况下如何进行上行数据传输的问题。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。

参见图2，图中示出了一种SR/BSR触发方法的流程，具体步骤如下：
步骤201、终端某个承载/逻辑信道有上行数据传输需求；
当终端某个承载/逻辑信道有上行数据传输需求但是终端在该承载/逻辑信道可用的numerology和/或TTI长度对应的物理资源上没有上行资源时，那么触发SR和/或BSR过程。
步骤202、终端选择SR和/或BSR传输资源。
终端某个承载/逻辑信道触发的SR和/或BSR是只能在该承载/逻辑信道对应的某个或者某些特定numerology和/或TTI长度对应的物理资源上传输，或者可以在任意numerology和/或TTI长度对应的物理资源上传输是协议约定，或者网络侧确定并通知给终端的。
如果SR(Scheduling Request，调度请求)/BSR(Buffer Status Report，缓冲区状态报告)只能在该承载/逻辑信道对应的某个或者某些特定numerology和/或TTI长度对应的物理资源上传输：
方式一、如果终端在所述numerology和/或TTI长度中的至少一个numerology和/或TTI长度对应的物理资源上是上行同步的，那么：
终端通过上述至少一个numerology和/或TTI长度对应的物理资源向网络侧发送SR，获取UL grant(上行调度授权)。如果UL grant刚好能够承载数据，则直接传输数据；否则，通过UL grant发送BSR信息。
方式二、如果终端在所述numerology和/或TTI长度对应的物理资源上都是上行失步的，那么：
终端通过上述至少一个numerology和/或TTI长度对应的物理资源向网络发起随机接入过程，获取上行同步以及UL grant；如果UL grant刚好能够承载数据，则直接发送数据；否则，通过UL grant发送BSR信息。
在本公开一些实施例中，SR和/或BSR任一numerology和/或TTI长度 对应的物理资源上传输
参见图3，图中示出了一种SR/BSR触发方法的流程，具体步骤如下：
步骤301：终端某个承载/逻辑信道有上行数据传输需求；
当终端某个承载/逻辑信道有上行数据传输需求但是终端在该承载/逻辑信道可用的numerology和/或TTI长度对应的物理资源上没有上行资源时，那么触发SR和/或BSR过程。
步骤302：终端选择SR和/或BSR传输资源。
终端某个承载/逻辑信道触发的SR和/或BSR是只能在该承载/逻辑信道对应的某个或者某些特定numerology和/或TTI长度对应的物理资源上传输，还是可以在任意numerology和/或TTI长度对应的物理资源上传输是协议约定，或者网络侧确定并通知给终端的。
如果SR和/或BSR可以在任意一个numerology和/或TTI长度对应的物理资源上传输：
方式一、如果终端在所述numerology和/或TTI长度中的至少一个numerology和/或TTI长度对应的物理资源上是上行同步的，那么：
其中之一：如果终端在所述上行同步的numerology和/或TTI长度对应的物理资源上有UL grant，那么通过该UL grant直接传输BSR信息，网络根据BSR信息确定终端有上行数据需要传输的承载/逻辑信道信息，并根据承载/逻辑信道以及numerology和/或TTI长度的映射关系，确定终端所述承载/逻辑信道对应的可用numerology和/或TTI长度，并从可用numerology和/或TTI长度中选择出要进行数据传输的numerology和/或TTI长度，并确定该numerology和/或TTI长度对应的物理资源。
需要说明的是，如果终端在所述选择的用于数据传输的numerology和/或TTI长度对应的物理资源上行失步，则可以触发终端在该numerology和/或TTI长度对应的物理资源上发起随机接入过程，获取上行同步。
其中之二：如果终端在所述上行同步的numerology和/或TTI长度对应的物理资源上没有UL grant，那么终端选择至少一个numerology和/或TTI长度可以发起随机接入过程，获取UL grant。
需要说明的是，如果获得UL grant的numerology和/或TTI长度对应的 物理资源可以用于承载终端当前有上行数据传输需求的承载/逻辑信道的数据，则如果UL grant可以承载所有要发送的数据，则直接利用该UL grant进行数据传输。
否则，利用该UL grant传输BSR信息。网络根据BSR信息确定终端有上行数据需要传输的承载/逻辑信道信息，并根据承载/逻辑信道以及numerology和/或TTI长度的映射关系，确定终端所述承载/逻辑信道对应的可用numerology和/或TTI长度，并从可用numerology和/或TTI长度中选择出要进行数据传输的numerology和/或TTI长度，并确定该numerology和/或TTI长度对应的物理资源。
如果所述选择的用于数据传输的numerology和/或TTI长度对应的物理资源上行失步，则可以触发终端在该numerology和/或TTI长度对应的物理资源上发起随机接入过程，获取上行同步。
方式二、如果终端在所述numerology和/或TTI长度对应的物理资源上都是上行失步的，那么：
终端通过上述至少一个numerology和/或TTI长度对应的物理资源向网络发起随机接入过程，获取上行同步以及UL grant。
需要说明的是，如果获得UL grant的numerology和/或TTI长度对应的物理资源可以用于承载终端当前有上行数据传输需求的承载/逻辑信道的数据，则如果UL grant可以承载所有要发送的数据，则直接利用该UL grant进行数据传输。
否则，利用该UL grant传输BSR信息。网络根据BSR信息确定终端有上行数据需要传输的承载/逻辑信道信息，并根据承载/逻辑信道以及numerology和/或TTI长度的映射关系，确定终端所述承载/逻辑信道对应的可用numerology和/或TTI长度，并从可用numerology和/或TTI长度中选择出要进行数据传输的numerology和/或TTI长度，并确定可用numerology和/或TTI长度对应的物理资源。
进一步地，如果终端在所述选择的用于数据传输的numerology和/或TTI长度对应的物理资源上行失步，则可以触发终端在该numerology和/或TTI长度对应的物理资源上发起随机接入过程，获取上行同步。
在上述实施例的基础上，下面再介绍本公开一些实施例，其中，本公开一些实施例适用的场景是基于小区/小区组进行上行同步维护，本公开一些实施例适用的场景是基于numerology和/或TTI长度进行上行同步维护。
本公开一些实施例中，终端在numerology和/或TTI长度对应的物理资源的上行同步维护。
网络侧在为终端添加小区时配置小区归属的TA(定时提前量)组信息。如果没有配置，则可以默认和第一个添加的小区归属同一个TA组。
上行同步维护定时器(TA timer)长度基于小区/小区组配置，如果不同小区组的TA timer长度相同，则可以基于终端只配置一个TA timer。
TA timer维护基于小区/小区组维护，包括TA timer的启动/重启/超时判断。对于numerology和/或TTI长度对应的物理资源其是否是上行同步的，则是根据该numerology和/或TTI长度对应的小区/小区组对应的TA timer是否在运行判断，如果该numerology和/或TTI长度对应的小区/小区组对应的TA timer在运行，则终端在该对应的物理资源上是上行同步的；否则是上行失步的。
本公开一些实施例中，终端在numerology和/或TTI长度对应的物理资源的上行同步维护
对于超大带宽小区，即使一个小区内，对于不同频点的numerology和/或TTI长度对应的物理资源其上行同步状态也可能不同，因此需要引入基于比小区粒度更小的基于numerology和/或TTI长度的上行同步维护。
基于numerology和/或TTI长度的TA timer长度是基于numerology和/或TTI长度配置的，如果不同numerology和/或TTI长度的TA timer长度相同，则可以基于终端只配置一个TA timer。
TA timer维护基于numerology和/或TTI长度组维护，包括TA timer的启动/重启/超时判断。对于numerology和/或TTI长度对应的物理资源其是否是上行同步的，则是根据该numerology和/或TTI长度对应的TA timer是否在运行判断，如果该numerology和/或TTI长度对应的TA timer在允许，则终端在该numerology和/或TTI长度对应的物理资源上是上行同步的；否则是上行失步的。
