Description

一种发送和接收调度请求的方法及通信装置
本申请要求于2019年8月2日提交国家知识产权局、申请号为201910713311.5、申请名称为“一种发送和接收调度请求的方法及通信装置”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
本申请实施例涉通信领域，尤其涉及一种发送和接收调度请求的方法及通信装置。
背景技术
长期演进(long term evolution，LTE)通信系统、第五代(5 th generation，5G)通信系统中，支持设备间的侧行(sidelink)通信，如：设备到设备(device to device，D2D)通信、车对一切(vehicle to everything，V2X)通信等，即终端设备之间可以利用为D2D通信配置的时频资源进行侧行通信。在做D2D或V2X的传输时，基站需要指示哪些资源用于Sidelink传输。
现有技术中，用户设备(user equipment，UE)有数据需要在Sidelink链路上传输时，UE先向基站发送调度请求(Scheduling Request，SR)，基站响应SR向UE发送上行授权的信息。UE可以在上行授权的资源上向基站缓存状态报告(buffer status report，BSR)，基站可以根据BSR确定UE在Sidelink链路上传输的数据大小，根据数据大小为UE在Sidelink链路上的传输分配资源。
上述方案导致为UE申请传输资源时有较大的时延，不能满足时延敏感业务的需求，影响传输性能。
发明内容
本申请实施例提供一种发送和接收调度请求的方法及通信装置，减少为终端申请传输资源的时延，尽可能满足时延敏感业务的需求，提高传输性能。
为达到上述目的，本申请实施例采用如下技术方案：
第一方面，提供了一种发送调度请求的方法，包括：第一终端在第一资源向网络设备发送第一调度请求，第一调度请求用于为第一终端的待发送数据请求资源，在第一资源上发送第一调度请求用于指示待发送数据的第一传输参数，其中，第一传输参数包括待发送数据的大小、待发送数据的服务质量参数和待发送数据的目的标识中的至少一项。此外，第一终端还可以从网络设备接收下行控制信息，下行控制信息指示用于发送待发送数据的第二资源，第二资源是网络设备根据第一传输参数分配的。
本申请实施例中，对网络设备和终端的行为进行了约定，终端在特定的SR资源(即本申请实施例所述的用于发送调度请求的资源)上发送SR(即调度请求)，可以包含或隐含指示一组传输参数，相应的，网络设备在该SR资源接收SR也可以确定终端所包含或隐含指示的传输参数，进而可以确定终端待发送数据的大小、QoS参数、目的标识等中的至少一项或多项的组合。可见，终端不需要花费时间先后上报SR和BSR来申请传输资源，网络设备在接收SR后就可以为终端待发送的数据分配资源，减少了终端申请传输资源的时延，尽可能满足时延敏感业务的需求，提高了传输性能。
结合第一方面，在第一方面的第一种可能的实现方式中，方法还包括：第一终端 获取第一信息，第一信息用于指示第一资源与第一传输参数之间的对应关系。
本申请实施例中，终端可以根据第一信息获知SR资源(即用于发送调度请求的资源)和传输参数之间的对应关系，在需要发送数据之前，可以根据实际的业务需求在第一信息指示的传输参数中选择合适的第一传输参数，并在第一传输参数对应的第一资源上发送第一调度请求，隐含指示第一传输参数。
结合第一方面或第一方面的第一种可能的实现方式，在第一方面的第二种可能的实现方式中，第一信息用于指示N个用于发送调度请求的资源和M组传输参数之间的对应关系，N个用于发送调度请求的资源包括第一资源，传输参数包括数据的大小、数据的服务质量参数和数据的目的标识中的至少一项；其中，N、M均为大于等于1的整数。
本申请实施例中，通过第一信息指示SR资源与传输参数之间的对应关系，终端或网络设备可以直接根据某个SR资源确定一个或多个传输参数，终端无需上报花费时间上报传输参数，网络设备就可以获知终端待发送数据的传输参数，进而为终端分配资源以发送所述待发送数据。
结合第一方面或第一方面的第一或第二种可能的实现方式，在第一方面的第三种可能的实现方式中，第一信息用于指示Y个参考传输参数与Y组用于发送调度请求的资源之间的对应关系，以及Y组用于发送调度请求的资源包括的X个用于发送调度请求的资源与X个偏移量之间的对应关系；第i组用于发送调度请求的资源中的每个资源对应的偏移量为每个资源对应的传输参数相对于第i组用于发送调度请求的资源对应的参考传输参数的偏移量，i为大于等于1小于等于Y的整数；其中，X个用于发送调度请求的资源包括第一资源，X、Y为大于等于1的整数。
本申请实施例中，通过第一信息指示参考传输参数、SR资源以及偏移量之间的对应关系，终端在一个SR资源上发送调度请求，隐含指示了一个参考传输参数和一个偏移量，根据参考传输参数和偏移量可以确定终端待发送数据的传输参数。由于SR资源是有限的，如果通过SR资源直接指示传输参数，能够指示的传输参数也是有限的，但是如果SR资源关联的是参考传输参数和偏移量，就可以通过有限的SR资源指示较大的传输参数范围，能够匹配终端更多的业务需求。
结合第一方面的第三种可能的实现方式，在第一方面的第四种可能的实现方式中，第一调度请求指示第一偏移量，第一偏移量为第一传输参数相对于第一参考传输参数的偏移量；第一参考传输参数为Y个参考传输参数中，与第一资源所在组对应的参考传输参数。

本申请实施例中，通过在第一资源上发送第一调度请求指示某个传输参数的一个值，这个值可能不能准确地体现终端的业务特性，还可以在第一调度请求中增加比特指示该传输参数的另外一个值，结合这两个值得到一个更贴近终端业务特性的值，根据获得的值为终端的待发送数据分配合适的资源。
结合第一方面或第一方面的第一至第六种可能的实现方式中的任意一种，在第一方面的第七种可能的实现方式中，第一调度请求包括数据大小缩放因子，数据大小缩放因子用于确定待发送数据的大小。
本申请实施例提供的方法适用于组播场景，终端通过在第一资源上发送第一调度请求指示第一数据大小，第一调度请求包括数据大小缩放因子，根据数据大小缩放因子和第一数据大小获得终端向群组发送数据的大小，根据终端向群组发送数据的大小分配资源，支持终端的组播业务。
结合第一方面或第一方面的第一至第七种可能的实现方式中的任意一种，在第一方面的第八种可能的实现方式中，方法还包括：第一终端在第二资源上向网络设备或第二终端发送待发送数据。
本申请实施例提供的方法适用于蜂窝链路，可以为终端在蜂窝链路上待发送的数据请求资源。还适用于侧行链路，可以为终端在侧行链路上待发送的数据请求资源。
第二方面，提供了一种接收调度请求的方法，包括：网络设备在第一资源上接收来自第一终端的第一调度请求，第一调度请求用于为第一终端的待发送数据请求资源；网络设备根据在第一资源上接收到第一调度请求确定待发送数据的第一传输参数，其中，第一传输参数包括待发送数据的大小、待发送数据的服务质量参数和待发送数据的目的标识中的至少一项；网络设备向第一终端发送下行控制信息，下行控制信息指示用于发送待发送数据的第二资源。
本申请实施例中，对网络设备和终端的行为进行了约定，终端在特定的SR资源(即本申请实施例所述的用于发送调度请求的资源)上发送SR(即调度请求)，可以包含或隐含指示一组传输参数，相应的，网络设备在该SR资源接收SR也可以确定终端所包含或隐含指示的传输参数，进而可以确定终端待发送数据的大小、QoS参数、目的标识等中的至少一项或多项的组合。可见，终端不需要花费时间先后上报SR和BSR来申请传输资源，网络设备在接收SR后就可以为终端待发送的数据分配资源，减少了终端申请传输资源的时延，尽可能满足时延敏感业务的需求，提高了传输性能。
结合第二方面，在第二方面的第一种可能的实现方式中，方法还包括：网络设备获取第一信息，第一信息用于指示第一资源与第一传输参数之间的对应关系。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
首先，对本发明实施例涉及的术语进行解释说明。
(1)调度请求(Scheduling Request，SR)
LTE中，如果终端有上行数据需要发送，终端需要向基站发送SR告知基站自己的数据传输需求，SR可以为终端待发送的数据请求资源。基站接收SR后可以决定是否为终端分配资源。
如图1所示，基站为SR分配了专用的资源(以下简称SR资源)，不同的SR资源占用不用的时域位置或频域位置，或时域位置、频域位置均不同，本申请实施例对此不做限制。终端可以在SR资源上发送SR。基站不知道终端什么时候发送SR，需要在SR资源上检测是否有SR上报。基站检测到SR后，可以获知终端的数据传输需求，进而决定是否为终端分配资源。具体为终端分配多少资源取决于基站的实现，一般分配足够发送BSR的资源。
同样在侧行链路(sidelink)通信中，终端也需要通过SR告知终端在sidelink链路上是否有数据传输需求，以便基站决定是否为终端在sidelink链路上发送的数据分配资源。
一种可能的实现方式中，SR可以是1比特。例如，“0”代表终端有数据传输需求，基站需要为终端待发送的数据分配资源；“1”代表终端没有数据传输需求，基站不需要为终端分配资源。或者，“1”代表终端有数据传输需求，基站需要为终端待发送的数据分配资源；“0”代表终端没有数据传输需求，基站不需要为终端分配资源。
(2)缓存状态报告(buffer status report，BSR)
终端除了利用SR告知基站自己的数据传输需求以外，还可以利用BSR上报待发送数据的大小。
示例的，参考图2，BSR包括destination ID(目的标识)、逻辑信道标识(logic channel group ID，LCG ID)以及buffer size(缓存数据大小)。一种可能的实现方式中，BSR只包括LCG ID以及buffer size。
其中，destination ID是数据接收方的标识。示例的，该destination ID可以是目的用户设备(user equipment，UE)的标识(target UE ID或者target ID)，destination ID也可以是业务类型的标识。示例的，业务类型的标识可以是单播业务标识、组播业务标识、广播业务标识中的至少一项。destination ID可以是几比特，用来表示不同的业务类型标识。例如，单播业务标识为00，组播业务标识为01，广播业务标识为10。业务类型的标识还可以是周期性业务标识或者非周期性业务标识。
LCG ID是与BSR绑定的逻辑信道或者逻辑信道组的标识，BSR用于指示与其绑定的逻辑信道或者逻辑信道组上的待传输数据的大小。逻辑信道组可以包括一个或者多个逻辑信道。
buffer size用于描述终端待传输数据的大小。例如，BSR中为buffer size预留的字段可以用索引值(index)来填充。索引值与buffer size对应，不同的索引值指示不同的buffer size。例如，index的取值为0～63中任一数值，不同的索引值表示不同的数据大小。本申请实施例中，可以将buffer size字段中填充的index称为BSR值。
(3)服务质量(quality of service，QoS)参数
QoS机制是一种网络安全机制，可以对不同的数据流提供不同的服务质量，即不同的数据流的QoS参数是不同的。不同的QoS参数有不同的QoS级别，数据流的QoS 级别可以标记数据流的优先级。通常，优先处理优先级高的数据流，为优先级较低的数据流提供较低的处理优先级，例如，在网络拥塞时可以丢弃优先级较低的数据流。
QoS参数可以是终端数据业务的QoS级别，例如，可以是每包优先权(prose per packet priority，PPPP)，也可以是QoS index。其中，QoS index可以是5QI。PPPP目前可以划分为8个级别，不同的PPPP参数可以有不同的QoS级别。5QI目前可以划分为5个QoS级别，不同的5QI参数可以有不同的QoS级别。当然，PPPP还可以划分为更多的QoS级别，QoS本申请实施例对此不作限制。
QoS参数还可以用来区分业务类型，例如，根据业务的QoS参数区分是增强型移动宽带(enhanced mobile broadband,eMBB)业务或者超可靠低时延通信(ultra reliable low latency communication,URLLC)业务。
图3给出了本申请提供的技术方案所适用的一种通信系统的示意图，该通信系统可以包括多个网络设备(仅示出了网络设备100)以及多个终端(图中仅示出了终端201和终端202)。图3仅为示意图，并不构成对本申请提供的技术方案的适用场景的限定。
其中，网络设备和终端之间可以通过蜂窝链路(Uu链路)进行上下行传输，终端之间可以通过侧行链路(sidelink链路)进行通信，例如D2D通信、V2X通信、机器类型通信(machine type communication，MTC)等。

参考图4，图3所示的通信系统还可以包括路边单元(Road Side Unit，RSU)，RSU单元可以集成车载设备的功能，也可以集成网络设备(例如，eNB或gNB)的功能，还可以是车载设备和网络设备设备的功能。一种可能的实现方式中，RSU可以是 UE类型的RSU(UE type RSU)。RSU可以接收来自应用服务器的数据，通过与终端之间的PC5接口将接收到的数据发送给终端201或终端202。
在图3或图4所示的通信系统中，终端201或终端202通过Uu链路向网络设备发送上行数据时，或者，终端201和终端202之间通过sidelink链路发送数据时，需要向网络设备请求传输资源。示例的，参考图5，待发送数据到达终端201后，终端201向网络设备100发送SR。终端接收SR后向终端201发送下行控制信息(downlink control information，DCI)1，DCI1用于指示发送BSR的上行资源。终端201在DCI1指示的资源上发送BSR，BSR用于指示待发送数据的大小。网络设备接收BSR后，根据BSR为待发送数据分配资源，向终端201发送DCI2，DCI2可以指示为待发送数据分配的资源。终端201接收DCI2，在DCI2指示的资源上发送数据。
值得注意的是，图5所示方案中，终端申请传输资源的过程有较大时延，不满足时延敏感业务的需求。

本申请实施例提供一种资源分配方法，如图7所示，所述方法包括以下步骤：
701、终端在第一资源向网络设备发送第一调度请求，所述第一调度请求用于为所 述终端的待发送数据请求资源，在所述第一资源上发送所述第一调度请求用于指示所述待发送数据的第一传输参数。所述第一传输参数包括所述待发送数据的大小、所述待发送数据的服务质量参数和所述待发送数据的目的标识中的至少一项。
需要说明的是，调度请求可以是本申请实施例所述的SR，第一资源是本申请实施例所述的SR资源中的任意一个，所述第一资源不同于目前通信系统中配置给侧行链路终端的用于传输SR的资源，不同于目前通信系统中配置给UU链路终端的用于传输SR的资源。其中，侧行链路终端指的是通过侧行链路与其他终端进行通信的终端，UU链路终端指的是通过UU链路与网络设备(例如，基站)进行通信的终端。待发送数据的大小可以是本申请实施例所述的BSR中的buffer size字段指示的数据大小，待发送数据的服务质量参数可以是本申请实施例所述的QoS参数，待发送数据的目的标识可以是本申请实施例所述的destination ID。所述待发送数据可以是终端与网络设备之间的Uu链路上待发送的数据，也可以是终端与其他终端之间的sidelink链路上待发送的数据。
具体实现中，预先在终端配置了第一信息，或者，网络设备通过信令向终端配置了第一信息。所述信令可以为无线资源控制(radio resource control，RRC)信令，媒体访问控制(media access control，MAC)信令或者物理层信令中的至少一项。此外，第一信息可以指示SR资源和传输参数之间的对应关系。本申请实施例中，第一信息有以下两种可能的实现：
第一种、预配置了多个SR资源和多组传输参数之间的对应关系，第一信息可以指示多个SR资源和多组传输参数之间的对应关系。终端查询预配置的第一信息，可以确定其中某个SR资源对应的一组(或多组)传输参数。
例如，在终端预配置了第一信息，所述第一信息用于指示N个用于发送调度请求的资源与M组传输参数之间的对应关系。所述N、M均为大于等于1的整数。其中，N可以等于M，也可以不同于M。当N与M相同，用于发送调度请求的资源与传输参数一一对应，不同的资源对应不同的传输参数；当N与M不同，一个用于发送调度请求的资源可以对应多组传输参数。
此外，用于发送调度请求的资源可以是本申请实施例所述的SR资源，所述M组传输参数中的每一组可以包括数据的大小、数据的服务质量参数和数据的目的标识中的一项或多项。所述N个用于发送调度请求的资源包括所述第一资源，因此终端根据第一信息可以确定与第一资源对应的一组(或多组)传输参数。示例的，所述终端查询第一信息确定与第一资源对应的传输参数。
示例的，第一信息指示的SR资源与传输参数之间的对应关系可以参考以下表1。
表1
Figure PCTCN2020105314-appb-000001
Figure PCTCN2020105314-appb-000002
需要说明的是，表1中与SR资源对应的传输参数可以包括缺省项(N/A)，即SR资源对应传输参数包括数据大小、目的标识、QoS参数中的一项或多项。表1中与SR资源在一行的传输参数称为与该SR资源对应的传输参数。
一种可能的实现方式中，以传输参数包括终端待发送数据的大小和目的标识为例，SR资源与BSR之间存在对应关系。示例的，可以预先将SR资源与BSR之间的对应关系配置在终端。终端可以在某个SR资源上发送SR，隐含指示该SR资源对应的BSR。相应的，网络设备在该SR资源上检测到SR，就可以根据该SR对应的(隐含指示的)BSR确定终端待发送数据的大小、待发送数据的目的标识，根据确定的待发送数据的大小、目的标识为终端分配资源。
具体实现中，可以根据SR资源的时域位置区分不同的SR资源，也可以根据SR资源的频域位置区分不同的SR资源，也可以根据SR资源的时域位置和频域位置区分不同的SR资源。此外，可以根据BSR值区分不同的BSR。
示例的，参考图8，SR资源1～SR资源4的时域位置相同，频域位置互不相同。SR资源1～SR资源4可以认为是四个不同的SR资源，分别对应四个不同的BSR。例如，SR资源1与BSR1对应，SR资源2与BSR2对应，SR资源3与BSR3对应，SR资源4与BSR4对应。
其中，BSR1～BSR4的值不同，例如，BSR1～BSR4的值分别为30、150、200、300bytes,或者30、150、200、300Kbytes。假设终端在SR资源2上发送SR，基站在SR资源2上检测到SR，可以根据BSR2为终端的待发送数据分配资源。
第二种、多个SR资源可以被划分成多组，每组SR资源对应一个参考传输参数，可以在终端配置多组SR资源与多个参考传输参数之间的对应关系，以及每个SR资源与偏移量的对应关系。SR资源对应的偏移量指的是该SR资源相对于相应的参考传输参数的偏移量，所谓“相应的参考传输参数”即该SR资源所在组对应的参考传输参数。终端在某个SR资源上发送调度请求，隐含指示了与该SR资源对应的一个偏移量，该偏移量为终端待发送数据的传输参数与相应的参考传输参数之间的偏移量。
示例的，在终端配置了第一信息，所述第一信息用于指示Y个参考传输参数与Y组用于发送调度请求的资源之间的对应关系，以及这Y组资源包括的所有X个用于发送调度请求的资源与X个偏移量之间的对应关系。其中，所述X个用于发送调度请求的资源包括所述第一资源，所述X、Y为大于等于1的整数。终端在第一资源上发送第一调度请求时，隐含指示了与第一资源对应的一个偏移量，网络设备可以根据该偏移量和以及第一资源所在组对应的参考传输参数来确定待发送数据的传输参数。
需要说明的是，X个用于发送调度请求的资源被划分成Y组，一组资源与一个传输参数范围建立对应关系。对于一个传输参数范围，确定一个参考传输参数，可以根据该参考传输参数和一个偏移量来确定该范围内的一个传输参数。因此，Y组资源可以对应Y个参考传输参数。此外，第i组用于发送调度请求的资源中的每个资源对应的偏移量为所述每个资源对应的传输参数相对于所述第i组用于发送所述调度请求的 资源对应的参考传输参数的偏移量，i为大于等于1小于等于Y的整数。
示例的，第一信息指示的SR资源与参考传输参数、偏移量之间的对应关系可以参考以下表2。
表2
Figure PCTCN2020105314-appb-000003
参考表2，第一信息可以指示SR资源所在的资源组，资源组对应的参考传输参数，SR资源对应的偏移量以及SR资源指示的传输参数。具体地，可以将SR资源、参考传输参数以及偏移量这三项的对应关系配置在终端，终端在一个SR资源上发送调度请求，隐含指示一个参考传输参数、一个偏移量，还可以指示待发送数据的传输参数。例如，终端在SR资源1上发送调度请求，隐含指示参考传输A以及偏移量Q1，即待发送数据的传输参数为A+Q1。
需要说明的是，根据参考传输参数和偏移量计算传输参数的方法不限于表2所示，即传输参数＝参考传输参数+偏移量，还可以是其他算法，例如，传输参数＝参考传输参数-偏移量，还可以是传输参数为任何根据参考传输参数以及偏移量作为输入参数的函数，该函数可以为线性函数或非线性函数。
一种可能的实现方式中，可以按照传输参数的值来划分传输参数范围。示例的，传输参数包括终端待发送数据的大小，可以根据一定的数据大小来划分不同的传输参数范围。以BSR为例，BSR值1～50为一个传输参数范围，BSR值51～100为一个传输参数范围，BSR值101～150为一个传输参数范围……依次类推。
或者，传输参数包括待发送数据的服务质量参数，可以根据QoS级别的基本来划分不同的传输参数范围。以PPPP为例，可以按照PPPP的QoS级别来进行划分不同的传输参数范围，示例的，PPPP至少包括8个QoS级别，其中，QoS级别1～3为一个范围，QoS级别4～6为一个范围，QoS级别7～8为一个范围……依次类推划分不同的范围。以5QI为例，可以根据5QI的QoS级别来划分不同的传输参数范围，QoS级别1为一个范围，QoS级别2为一个范围，QoS级别3为一个范围……依次类推划分不同的范围。
又或者，传输参数包括终端待发送数据的目的标识，可以根据目的标识指示的业务类型来划分不同的传输参数范围。假设目的标识00指示单播业务，目的标识01指示组播业务，目的标识10指示广播业务。根据目的标识是否为00，是否为01，或是 否为10来划分不同的传输参数范围，例如，目的标识为00的所有传输参数为一个传输参数范围，目的标识为10的所有传输参数为一个传输参数范围，目的标识为01的所有传输参数为一个传输参数范围。
此外，还可以是上述待发送数据的大小，服务质量参数和目的标识中的任意组合划分传输参数范围。例如，BSR值是1～50且QoS基本为1～3的传输参数为一个范围，BSR值是1～50且QoS级别为4～6的传输参数为一个范围，BSR值是51～100且QoS级别为1～3为的传输参数为一个范围，BSR值是51～100且QoS级别为4～6的传输参数为一个范围……依次类推划分不同的范围。
一种可能的实现中，终端在第一资源上发送的第一调度请求还可以指示第一偏移量，所述第一偏移量为所述第一传输参数相对于第一参考传输参数的偏移量；所述第一参考传输参数为所述Y个参考传输参数中，与所述第一资源所在组对应的参考传输参数。示例的，第一资源的时频位置与第一偏移量对应，终端在第一资源上发送第一调度请求，隐含指示了第一偏移量。或者，可以将第一偏移量tagged在第一调度请求中，即第一调度请求包括第一偏移量。
一种可能的实现方式中，以传输参数包括数据大小为例，SR资源与BSR之间存在对应关系。示例的，可以建立SR资源与BSR范围(即本申请实施例所述的传输参数范围)之间的对应关系，将SR资源划分为多组，不同组SR资源对应不同的BSR值或者BSR范围。
具体地，可以根据BSR值来划分BSR范围，例如，BSR范围1是BSR值1～10，BSR范围2是BSR值11～20，BSR范围3是BSR值21～30，BSR范围4是BSR值31～40。还可以将SR资源资源划分成4组，例如，第一组包括SR1～SR3，与BSR范围1对应；第二组包括SR4～SR6，与BSR范围2对应；第三组包括SR7～SR9，与BSR范围3对应；第四组包括SR10～SR12，与BSR范围4对应。
此外，每个BSR范围有一个参考BSR值(即本申请实施例所述的参考传输参数)，即每组SR资源对应一个参考BSR值。每个SR资源还可以对应一个偏移量。需要说的是，SR资源对应的偏移量为该SR资源指示的BSR值，与该SR资源所在SR资源组对应的参考BSR值之间的偏移量。例如，BSR范围1内的参考BSR值为4，第一组SR资源(即SR1～SR3)对应的参考BSR值为4，SR1对应的偏移量为A，A是相对于BSR值4的偏移量；BSR范围2内的参考BSR值为16，第一组SR资源(即SR4～SR7)对应的参考BSR值为16，SR4对应的偏移量为B，B是相对于BSR值16的偏移量。
一种可能的实现方式中，可以通过SR资源的时频位置来指示SR资源对应的参考传输参数和偏移量。具体地，SR资源的时域位置与参考传输参数之间存在对应关系，SR资源的频域位置与偏移量之间存在对应关系，SR资源的时域位置可以隐式指示参考传输参数，SR资源的频域位置可以隐式指示偏移量；或者，SR资源的频域位置与参考传输参数之间存在对应关系，SR资源的时域位置与偏移量之间存在对应关系，SR资源的频域位置可以隐式指示参考传输参数，SR资源的时域位置可以隐式指示偏移量。
一种实施例中，SR资源的时域位置指示不同的BSR范围，SR资源的频域位置指示不同的偏移量。例如，参考图9，时域位置1对应BSR范围1，即时域位置1指示BSR范围1内的参考BSR值为A，SR1的频域位置指示偏移量offset1，offset1是相对 于A的偏移量；SR2的频域位置指示偏移量offset2，offset2是相对于A的偏移量；SR3的频域位置指示偏移量offset3，offset3是相对于A的偏移量。
时域位置2对应BSR范围2，即时域位置2指示BSR范围2内的参考BSR值为B，SR4的频域位置指示偏移量offset4，offset4是相对于B的偏移量；SR5的频域位置指示偏移量offset5，offset5是相对于B的偏移量；SR6的频域位置指示偏移量offset6，offset6是相对于B的偏移量。
作为另一种实施例，SR资源的频域位置既可以指示不同的BSR范围，还可以指示不同的偏移量。例如，参考图10，SR1～SR3属于频段1，频段1为BSR范围1，即频段1指示BSR范围1内的参考BSR值为A，SR1的频域位置指示偏移量offset1，offset1是相对于A的偏移量；SR2的频域位置指示偏移量offset2，offset2是相对于A的偏移量；SR3的频域位置指示偏移量offset3，offset3是相对于A的偏移量。
SR4～SR6属于频段2，频段2为BSR范围2，即频段2指示BSR范围2内的参考BSR值为B，SR4的频域位置指示偏移量offset4，offset4是相对于B的偏移量；SR5的频域位置指示偏移量offset5，offset5是相对于B的偏移量；SR6的频域位置指示偏移量offset6，offset6是相对于B的偏移量。
作为另一种实施例，SR资源的时频位置只指示参考BSR值，可以在实际发送的调度请求(SR)中增加额外的比特指示对应的偏移量。例如，参考图11，SR1～SR3的频域位置相同，时域位置不同。SR1的时域位置指示参考BSR值“4”，SR2的时域位置指示参考BSR值“30”，SR3的时域位置指示参考BSR值“50”。假设终端在SR1的资源上发送调度请求，隐含指示参考BSR值“4”，该调度请求中包括偏移量Q1，Q1为待发送数据的BSR值相对于参考BSR值“4”的偏移量，网络设备可以根据偏移量Q1和参考BSR值“4”确定待发送数据的BSR值，也可以确定待发送数据的大小，进而分配根据待发送数据的大小分配资源。
作为另一种实施例，SR资源的时频位置只指示偏移量，可以在实际发送的调度请求(SR)中增加额外的比特指示参考BSR值。例如，参考图12，SR1～SR3的时域位置相同，频域位置不同。SR1的频域位置指示偏移量Q1，SR2的频域位置指示偏移量Q2，SR3的频域位置指示偏移量Q3。假设终端在SR2的资源上发送调度请求，隐含指示偏移量Q2，该调度请求中包括参考BSR值“15”，Q2为待发送数据的BSR值相对于参考BSR值“15”的偏移量，网络设备可以根据偏移量Q2和参考BSR值“15”确定待发送数据的BSR值，也可以确定待发送数据的大小，进而分配根据待发送数据的大小分配资源。
需要说明的是，以不同的时间粒度或时间单元进行指示SR资源的时域位置，其中，时间单元或时间粒度可以是时域内的正整数个符号、迷你时隙、时隙、子帧等，或者时域内0.5毫秒(millisecond，ms)、1ms、5ms等正整毫秒或正整数秒。在本申请实施例中，正整数可以是大于等于1的整数，例如1、2、3或更大的整数。其中，迷你时隙可以为3个符号，4个符号或者7个符号等任何自然数个符号。此外，以物理资源块(physical resource block，PRB)、资源元(resource element，RE)、subband、带宽部分(bandwidth partial，BWP)中的任意一个SR资源的频域位置。
具体实现方式中，终端有数据传输需求之后，可以在本地获取第一信息，根据第 一信息确定与终端的数据传输需求匹配的第一传输参数以及第一传输参数对应的第一资源。示例的，第一信息中数据大小(单位：比特)100、150、200、300对应的SR资源分别为SR资源1、SR资源2、SR资源3、SR资源4。假设终端实际待发送的数据大小为80比特，与100比特最接近，可以认为与终端的数据传输需求匹配的第一传输参数为“100”。相应的，第一资源为第一信息中与数据大小“100”对应的SR资源1。
此外，终端可以在第一资源上发送第一调度请求，由于第一资源与第一传输参数存在预配置的对应关系，终端在第一资源上发送第一调度请求的行为可以隐含指示：终端待发送数据的传输参数为与第一资源对应的第一传输参数。
702、网络设备在第一资源上接收第一调度请求，确定第一传输参数。
可以理解的是，预先在网络设备也配置了第一信息，第一信息可以指示第一资源与第一传输参数之间的对应关系。第一信息的具体实现参考步骤701的描述，在此不做赘述。因此，当网络设备在第一资源上接收到第一调度请求，网络设备可以确定与第一资源对应的第一传输参数。
在第一信息的第一种实现方式中，网络设备获取第一信息可以确定N个用于发送调度请求的资源与M组传输参数之间的对应关系。在第一资源上接收到第一调度请求后，可以查询第一信息确定与第一资源对应的一组传输参数，作为终端待发送数据的传输参数。
示例的，假设第一信息以表1的形式配置在网络设备。网络设备在SR资源2上接收到调度请求，查询表1确定与SR资源2对应的传输参数，即数据大小2、目的标识2以及QoS参数2。
在第一信息的第二种实现方式中，网络设备获取第一信息可以确定Y个参考传输参数与Y组用于发送调度请求的资源之间的对应关系，以及这Y组资源包括的所有X个用于发送调度请求的资源与X个偏移量之间的对应关系。在第一资源上接收到第一调度请求后，可以查询第一信息确定与第一资源对应的参考传输参数和偏移量，根据该参考传输参数和偏移量确定终端待发送数据的传输参数。
示例的，假设第一信息以表2的形式配置在网络设备。网络设备在SR资源3上接收调度请求，查询表2确定与SR资源3对应的参考传输参数A以及偏移量Q3，即终端待发送数据的传输参数为A+Q3。
703、网络设备根据第一传输参数确定第二资源。
一种可能的实现方式中，第一传输参数包括待发送数据的大小，可以根据数据大小分配第二资源，第二资源足够承载待发送数据。
另一种可能的实现方式中，第一传输参数包括待发送数据的目的标识，假设待发送数据的目的标识用于指示终端的业务类型，可以根据业务类型分配第二资源。
在不同类型的业务不共享资源池的场景下，即单播、组播及广播业务有各自对应的资源池。当待发送数据的目的标识指示的业务类型为单播业务，则在单播业务对应的资源池为终端的待发送数据分配资源，以支持终端的单播业务。当待发送数据的目的标识指示的业务类型为组播业务，则在组播业务对应的资源池为终端的待发送数据分配资源，以支持终端的组播业务；当待发送数据的目的标识指示的业务类型为广播 业务，则在广播业务所对应的资源池为终端的待发送数据配置资源。
另一种可能的实现方式中，第一传输参数包括待发送数据的服务质量参数，可以根据服务质量参数分配第二资源，第二资源能够支持待发送数据的服务质量参数。例如，第一传输参数包括QoS参数(例如，PPPP或5QI)，且QoS参数的QoS级别较高，则分配较大的资源，以满足终端业务的数据服务质量需求。或者，QoS参数的QoS级别较高，则分配时域上较早的资源。或者，QoS参数的QoS级别较高，则分配的资源数至少应该在调制解调编码策略(modulation and coding scheme，MCS)较低仍可以满足终端业务的数据服务质量需求。或者，QoS参数的QoS级别较高，在资源有限的情况下优先响应第一调度请求，为终端分配第二资源。或者，QoS参数的QoS级别较高，在资源共享时将第一调度请求对应的业务配置较大的目标功率值。
相应的，QoS参数的QoS级别较低，则分配较小的资源，以满足终端业务的数据服务质量需求。或者，QoS参数的QoS级别较低，则分配时域上较晚的资源。或者，QoS参数的QoS级别较低，在资源有限的情况下不响应第一调度请求，不为终端分配第二资源。或者，QoS参数的QoS级别较低，在资源共享时将第一调度请求对应的业务配置较低的目标功率值。
704、网络设备向终端发送下行控制信息，所述下行控制信息指示用于发送所述待发送数据的第二资源。
705、终端通过第二资源向网络设备或其他终端发送所述待发送数据。
需要说明的是，终端可以通过侧行链路与其他终端(例如，第二终端)进行通信。在向其他终端发送数据之前，终端通过第一调度请求向网络设备请求用于待发送数据的第二资源。可以理解的是，网络设备接收第一调度请求后，在侧行链路资源池中为待发送数据分配资源，即第二资源可以是侧行链路资源池中的资源。当然，第二资源也可以属于侧行链路可用的资源，而不受限于侧行链路资源池。在步骤705中，终端可以通过第二资源向其他终端发送所述待发送数据，即所述待发送数据为侧行链路上的数据。
此外，终端还可以通过蜂窝链路与网络设备进行通信。在向网络设备发送数据之前，终端向网络设备发送第一调度请求向网络设备请求用于待发送数据的第二资源。可以理解的是，网络设备接收第一调度请求后，在蜂窝链路资源池中为待发送数据分配资源，即第二资源可以是蜂窝链路资源池中的资源。当然，第二资源也可以属于蜂窝链路可用的资源，而不受限于蜂窝链路资源池。在步骤705中，终端可以通过第二资源向网络设备发送所述待发送数据，即所述待发送数据为蜂窝链路上的数据。
可选的，所述第一调度请求还可以包括第二传输参数，所述第二传输参数包括所述待发送数据的大小、所述待发送数据的服务质量参数和所述待发送数据的目的标识中的至少一项。第一传输参数和第二传输参数包括的参数可以不同，网络设备可以根据结合第一传输参数和第二传输参数了解待发送数据的属性。例如，第一传输参数包括待发送数据的大小和待发送数据的目的标识，第二传输参数包括待发送数据的服务质量参数。或者，第一传输参数包括待发送数据的目的标识，第二传输参数包括待发送数据的大小和待发送数据的服务质量参数。
可选的，终端还可以在第一调度请求中增加(tag)额外的比特来指示一些传输参 数。另外，网络设备在第一资源上接收到第一调度请求，隐含指示了一些传输参数。网络设备可以结合隐含指示的传输参数以及第一调度请求tag的比特指示的传输参数来确定终端待发送数据的传输参数。例如，在第一资源上发送第一调度请求指示了待发送数据的大小A，在第一调度请求tag的比特指示了待发送数据的服务质量参数B，网络设备可以根据待发送数据的大小A、待发送数据的服务质量参数B来确定用于发送所述待发送数据的第二资源。
具体实现中，第一调度请求中t个比特，可以指示某个传输参数的2 t个状态。例如，第一调度请求中额外增加3bit，可以表示8种状态，这8个状态可以对应8个不同的BSR。其中，不同的BSR可以是BSR值不同的BSR。
可选的，在第一信息的第二种实现方式中，网络设备在第一资源上接收到第一调度请求隐含指示了第一调度请求对应的参考传输参数，还可以在第一调度请求中增加额外的比特指示第一调度请求对应的偏移量。例如，第一调度请求中增加t个比特，可以指示2 t个不同的偏移量。取t＝2，可以指示4个不同的偏移量。具体地，00指示偏移量Q1，01指示偏移量Q2，10指示偏移量Q3，11指示偏移量Q4。假设网络设备在第一资源上接收到第一调度请求隐含指示了参考传输参数A，第一调度请求中额外增加的比特为00，网络设备可以根据参考传输参数A以及偏移量Q1确定待发送数据的传输参数。
可选的，在第一信息的第二种实现方式中，网络设备在第一资源上接收到第一调度请求隐含指示了第一调度请求对应的偏移量，还可以在第一调度请求中增加额外的比特指示第一调度请求对应的参考传输参数。例如，第一调度请求中增加t个比特，可以指示2 t个不同的参考传输参数。取t＝1，可以指示2个不同的参考传输参数。具体地，0指示参考传输参数A，1指示参考传输参数B。假设网络设备在第一资源上接收到第一调度请求隐含指示了偏移量Q2，第一调度请求中额外增加的比特为1，网络设备可以根据参考传输参数B以及偏移量Q2确定待发送数据的传输参数。
可选的，当终端在侧行链路上有组播业务，终端要向一组终端发送数据之前，终端可以向网络设备发送调度请求为所有待发送的数据请求资源。一种可能的实现方式中，终端可以在第一资源上发送第一调度请求，隐式指示向一个终端发送的数据的大小。另外，在第一调度请求中增加额外的比特指示数据大小缩放因子，所述数据大小缩放因子用于确定该终端所有待发送数据的大小。假设所述在所述第一资源上接收所述第一调度请求用于指示第一数据大小，网络设备可以利用所述数据大小缩放因子对所述第一数据大小进行缩放处理，获得所述待发送数据的大小。例如，发送UE需要向群组中的多个UE发送数据，发送UE可以根据传输参数与SR资源的对应关系，在一个SR资源发送第一调度请求隐式指示BSR值“15”。另外，第一调度请求中额外增加的比特指示的数据大小缩放因子为“3”。网络设备在该SR资源接收到第一调度请求，就可以确定BSR值“15”。还可以从第一调度请求中解析出额外的比特，解析出的比特指示数据大小缩放因子为“3”，网络设备确定实际BSR值为15*3，即根据BSR值“45”确定实际待发送数据的大小。
具体地，在第一调度请求中增加s个比特，可以指示2 s个不同的数据大小缩放因子。例如，该额外增加2比特，可以表示4个不同的数据大小缩放因子。其中，“00” 代表数据大小缩放因子2，“01”代表数据大小缩放因子3，“10”代表数据大小缩放因子4，“11”代表数据大小缩放因子5。
需要说明的是，数据大小缩放因子可以是群组中需要接收数据的终端数量，也可以是其他数值，本申请实施例对此不作限制。额外增加的比特的各个状态值与数据大小缩放因此之间的对应关系可以是预配置的，或者，也可以是通过信令配置的。
此外，当额外增加比特指示传输参数，且额外增加比特指示数据缩放因子，需要增加比特指示增加的比特指示的是传输参数还是数据缩放因子。例如，在第一信息的第二种可能的实现方式中，网络设备在第一资源上接收到第一调度请求隐含指示了第一调度请求对应的参考传输参数，在第一调度请求中增加额外的比特指示第一调度请求对应的偏移量。假设增加3比特来指示偏移量，则还需要在增加1比特来指示增加的这3比特指示的是偏移量，例如，第一调度请求中额外增加了4比特“0001”，其中，第一个比特“0”用于指示第一调度请求额外增加的比特用于指示偏移量，后三个比特“001”用于指示偏移量。
或者，第一调度请求中增加2比特来指示数据大小缩放因子，则还需要在增加1比特来指示增加的这3比特指示的是数据大小缩放因子，例如，第一调度请求中额外增加了4比特“1010”，其中，第一个比特“1”用于指示第一调度请求额外增加的比特用于指示数据大小缩放因子，后个比特“010”用于指示数据大小缩放因子。
或者，可以约定第一调度请求中增加的前几比特为偏移量，后几比特为数据大小缩放因子。或者，约定第一调度请求中增加的前几比特为数据大小缩放因子，后几比特为数据偏移量。
可选的，所述第一调度请求还用于指示第一数据大小、第一服务质量参数和第一目的标识中的至少一项；所述在所述第一资源上发送所述第一调度请求用于指示第二数据大小、第二服务质量参数和第二目的标识中的至少一项。
所述第一数据大小和所述第二数据大小用于确定所述待发送数据的大小，所述第一服务质量参数和所述第二服务质量参数用于确定所述待发送数据的服务质量参数，所述第一目的标识和所述第二目的标识用于确定所述待发送数据的目的标识。
例如，当在第一资源上发送第一调度请求隐含指示了第一数据大小，第一调度请求tag的比特也指示了第二数据大小，可以根据第一数据大小、第二数据大小确定待发送数据的大小。示例的，设置特殊的函数，该函数的输入为第一数据大小、第二数据大小，输出为待发送数据的大小。该函数可以是也可以对第一数据大小和第二数据大小进行加权求和，第一数据大小的权重系数、第二数据大小的权重系数可以相同也可以不同。例如，第一数据大小、第二数据大小的权重系数均为0.5。
可选的，终端在不同时间的业务可能发生变化，可以根据业务的持续时长设置SR资源与传输参数之间的对应关系的有效时长，并在有效时长开始时激活相应的对应关系，在有效时长结束时去激活该对应关系。也可以为网络设备在不同的持续时长内激活相应的SR资源与传输参数之间的对应关系，终端根据相应的激活应用相应的SR资源与传输参数之间的对应关系。
例如，终端在第一时长内终端的业务与终端在第二时长的业务不同，第一时长内SR资源与传输参数之间的对应关系，可以与第二时长内SR资源与传输参数之间的对 应关系不同。示例的，第一时长内SR资源与传输参数之间的对应关系1包括：SR资源1与BSR1对应、SR资源1与QoS级别3对应；SR资源2与BSR2对应、SR资源2与QoS级别1对应；第二时长内SR资源与传输参数之间的对应关系2包括：SR资源1与BSR2对应、SR资源1与QoS级别3对应；SR资源2与BSR1对应、SR资源2与QoS级别1对应。在第一时长内激活对应关系1，在第二时长内激活对应关系2。
本申请实施例还提供一种资源分配方法，如图13所示，所述方法包括以下步骤：
1301、终端向网络设备发送第一调度请求，所述第一调度请求用于为所述终端的待发送数据请求资源，所述第一调度请求包含第一传输参数的信息。所述第一传输参数包括所述待发送数据的大小、所述待发送数据的服务质量参数、所述待发送数据的目的标识中的至少一项。
本申请实施例中，在第一调度请求中增加额外的比特，增加的比特可以称为是第一传输参数的信息。网络设备可以根据第一传输参数的信息确定第一传输参数。
以第一传输参数包括待发送数据的大小为例，可以通过r个比特指示2 r个BSR值。具体地，预先在终端配置r个比特的状态与不同的BSR值之间的对应关系，终端可以根据实际的发送需求在第一调度请求中增加相应的比特，指示相应的BSR值。示例的，通过2个比特指示4个BSR值，其中，“00”指示BSR值“15”，“01”指示BSR值“30”，“10”指示BSR值“50”，“11”指示BSR值“100”。假设在第一调度请求中增加“10”，则指示BSR值“50”。
以第一传输参数包括待发送数据的目的标识为例，目标标识可以表示业务类型。可以通过2个比特指示单播、组播、广播这三种不同的业务类型。具体地，预先在终端配置2个比特的状态与单播、组播、广播之间的对应关系，终端可以根据实际的业务类型在第一调度请求中增加相应的比特，指示业务类型。示例的，通过2个比特指示业务类型，其中，“00”指示单播，“01”指示组播，“10”指示广播。假设在第一调度请求中增加“10”，则指示的业务类型为广播。
以第一传输参数包括待发送数据的服务质量参数为例，可以通过p个比特指示2 p个QoS级别，预先在终端配置p个比特的状态与不同的QoS级别之间的对应关系。以5QI为例，5QI包括5个QoS级别，其中“000”代表QoS级别1，“001”代表QoS级别2，“010”代表QoS级别3，“011”代表QoS级别4，“100”代表QoS级别5。假设在第一调度请求中增加“010”，则指示QoS级别3。
此外，当额外增加比特指示待发送数据的大小、待发送数据的服务质量参数和待发送数据的目的标识，需要额外增加比特指示哪些比特用于指示待发送数据的大小，哪些比特用于指示待发送数据的服务质量参数，哪些比特用于指示待发送数据的目的标识，哪些比特用于指示所述待发送数据的缩放因子。或者，预先约定哪些比特用于指示待发送数据的大小，哪些比特用于指示待发送数据的服务质量参数，哪些比特用于指示待发送数据的目的标识，哪些比特用于指示所述待发送数据的缩放因子。
1302、网络设备接收第一调度请求，获取第一传输参数的信息。
网络设备接收第一调度请求，根据第一调度请求中额外增加的比特确定第一传输参数的信息。
例如，第一调度请求中增加r个比特指示BSR值。具体地，预先在网络设备配置 r个比特的状态与不同的BSR值之间的对应关系，示例的，通过2个比特指示4个BSR值，其中，“00”指示BSR值“15”，“01”指示BSR值“30”，“10”指示BSR值“50”，“11”指示BSR值“100”。假设网络设备识别出第一调度请求中增加的比特是“10”，则确定第一传输参数的信息是“10”，即第一传输参数包括：BSR值“50”。
或者，第一调度请求中增加2个比特指示单播、组播、广播这三种不同的业务类型。具体地，预先在网络设备配置2个比特的状态与单播、组播、广播之间的对应关系。示例的，通过2个比特指示业务类型，其中，“00”指示单播，“01”指示组播，“10”指示广播。假设网络设备识别出第一调度请求中增加的比特是“10”，确定第一传输参数的信息是“10”，即第一传输参数包括：广播业务类型。
又或者，在第一调度请求中增加p个比特指示2 p个QoS级别，预先在网络设备配置p个比特的状态与不同的QoS级别之间的对应关系。以5QI为例，5QI包括5个QoS级别，其中“000”代表QoS级别1，“001”代表QoS级别2，“010”代表QoS级别3，“011”代表QoS级别4，“100”代表QoS级别5。假设网络设备识别出第一调度请求中增加的比特是“010”，确定第一传输参数的信息是“010”，即第一传输参数包括：QoS级别3。
1303、网络设备根据第一传输参数的信息确定第一传输参数，根据第一传输参数分配资源。所述资源用于发送所述发送数据。
具体实现参考图7所示方法关于步骤703的描述，在此不做赘述。
1304、网络设备向终端发送向终端发送下行控制信息，所述下行控制信息指示用于发送所述待发送数据的第二资源。
1305、终端通过第二资源向网络设备或其他终端发送所述待发送数据。
具体实现参考图7所示方法关于步骤705的描述，在此不做赘述。
可选的，所述方法还包括：所述第一终端获取M组传输参数的信息；所述M组传输参数包括所述第一传输参数。
本申请实施例，可以预先将多组传输参数的信息配置在网络设备和终端，终端可以根据实际的业务需求选择合适的传输参数，将该传输参数的信息(例如，几比特)增加到调度请求中。网络设备接收调度请求后，可以从中解析出该传输参数的信息，根据本地配置的传输参数的信息，确定调度请求中的信息指示的传输参数。例如，BSR1的信息是“00”，BSR2的信息是“01”，BSR3的信息是“10”，BSR4的信息是“11”，在调度请求中增加“00”指示BSR1，网络设备可以根据BSR1分配资源。
可选的，当第一传输参数包括待发送数据的大小，第一传输参数还可以包括数据大小缩放因子。
可以理解的是，当终端在侧行链路上有组播业务，终端要向一组终端发送数据之前，终端可以向网络设备发送调度请求为所有待发送的数据请求资源。一种可能的实现方式中，终端可以向网络设备发送第一调度请求，第一调度请求中增加比特，增加的比特称为第一传输参数的信息，可以指示待发送数据的大小以及数据大小缩放因子。
假设第一调度请求中增加的比特指示第一数据大小，网络设备可以利用所述数据大小缩放因子对所述第一数据大小进行缩放处理，获得所述待发送数据的大小(即终 端向一组终端发送的所有待发送数据的大小)。例如，发送UE需要向群组中的多个UE发送数据，发送UE可以在第一调度请求中增加比特指示BSR值“15”。另外，第一调度请求中还可以增加比特指示数据大小缩放因子为“3”。网络设备接收到第一调度请求，就可以确定BSR值“15”和数据大小缩放因子为“3”，网络设备确定实际BSR值为15*3，即根据BSR值“45”确定实际待发送数据的大小。
具体地，在第一调度请求中增加s个比特，可以指示2 s个不同的数据大小缩放因子。例如，该额外增加2比特，可以表示4个不同的数据大小缩放因子。其中，“00”代表数据大小缩放因子2，“01”代表数据大小缩放因子3，“10”代表数据大小缩放因子4，“11”代表数据大小缩放因子5。
需要说明的是，数据大小缩放因子可以是群组中需要接收数据的终端数量，也可以是其他数值，本申请实施例对此不作限制。额外增加的比特的各个状态值与数据大小缩放因此之间的对应关系可以是预配置的，或者，也可以是通过信令配置的。
图13所示的方法中，终端可以在调度请求中增加比特指示待发送数据的传输参数，终端不需要花费时间先后上报SR和BSR来申请传输资源，网络设备在接收SR后就可以为终端待发送的数据分配资源，减少了终端申请传输资源的时延，尽可能满足时延敏感业务的需求，提高了传输性能。另外，在调度请求中增加少量比特就指示传输参数的信息，无需在调度请求中tag全部的传输参数，也可以节省开销，提高通信性能。
