背景技术
终端直连通信技术(Device to Device，D2D)是指终端(UE)之间可以直接通信，不需要经过网络设备的传输或转发。D2D通信中，终端之间的链路定义为副链路(Sidelink)，终端称为副链路终端(Sidelink UE)。车对外界的信息交换(Vehicle to everything，V2X)是D2D的一种应用。
Sidelink UE在无线空口PC5引入了载波聚合(PC5carrier aggregation,PC5 CA)功能，副链路终端可以在多个PC5载波上进行收发，从而进一步提高数据吞吐率。关于终端在数据发送时，选择哪些候选PC5载波做载波聚合，是基于UE射频(RF)能力、当前信道拥塞率(Channel Busy ratio，CBR)、UE业务近距离通信数据分组优先级(Prose Per Packet Priority，PPPP)等因素的综合考虑，从而基站通过配置/预配置合适的参数控制对Sidelink UE PC5载波选择的规则。
同时，在5G网络中，引入了带宽部分(BandWitdh Part，BWP)，副链路终端可以在BWP上进行收发，不需要在整个频带上进行收发。
相关技术中，同一个业务，针对不同的业务数据单元(service Data Unit，SDU)有不同的PPPP、近距离通信数据分组可靠性(ProSe Per-Packet Reliability，PPPR)和不同的通信范围(communication range)要求。
然而结合Communication range如何选择传输载波或BWP标准还没有定论。

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作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。
请参考图1，图1为本公开实施例的副链路的传输资源选择方法的流程示意图，该方法应用于终端，包括：
步骤11：根据待发送的业务数据包的选择参数的需求信息，以及传输资源对应的选择参数的配置信息，为所述业务数据包选择传输所用的所述传输资源；其中，所述选择参数包括所述业务数据包的通信范围，所述传输资源包括载波和/或BWP。
本公开实施例中，副链路终端在进行载波和/或BWP的选择时，考虑待发送业务数据包的通信范围，使得选择的载波和/或BWP能够符合业务数据包的通信距离需求，提高传输性能。
本公开实施例中，所述业务数据包的通信范围的需求信息可以包括以下信息中的至少一项：
通信距离需求等级信息；
最小通信距离需求信息；
最大通信距离需求信息；
通信距离范围需求信息。
其中，通信距离需求等级信息例如可以为高、中、低等信息。
本公开实施例中，所述根据待发送业务数据包的选择参数的需求信息，以及传输资源对应的选择参数的配置信息，为所述业务数据包选择传输所用的所述传输资源的步骤，由所述终端的接入层执行。
进一步地，所述根据待发送业务数据包的选择参数的需求信息，以及传输资源对应的选择参数的配置信息，为所述业务数据包选择传输所用的所述传输资源的步骤之前，还包括：所述接入层接收所述终端的应用层发送的所述业务数据包的选择参数的需求信息。
具体地，所述终端的应用层可以为每个发往接入层的数据包提供一个通信范围的需求信息，如果从应用层发下来的数据包没有携带通信范围的需求信息，说明该业务数据包无通信范围需求。
本公开实施例中，在选择载波和/或BWP时，除了考虑业务数据包的通 信范围之外，还可以考虑其他选择参数，下面将举例进行说明。
本公开实施例中，在选择载波和/或BWP时，除了考虑业务数据包的通信范围之外，还可以考虑信道拥塞率(Channel Busy ratio，CBR)，使得业务数据包能够在信道拥塞率较低的载波和/或BWP上传输，提高传输性能。
在发送业务数据包时，通常需要考虑时延(Max end-to-end latency)的需求，R14(LTE R14版本)主要是通过近距离通信数据分组优先级(ProSe Per-Packet Priority，PPPP)体现，终端的ProSe上层(例如，above PC5 access stratum，接入层以上的应用层)将数据包发往下层(PC5 access stratum，PC5接入层)过程中，ProSe上层会给每个数据包提供一个PPPP值。PPPP最大可划分8组，取值0～7。PPPP值越小，业务数据包时延要求越高，传输的优先级越高，一个业务数据包可以对应1个PPPP。本公开实施例中，在选择载波和/或BWP时，除了考虑业务数据包的通信范围之外，还可以考虑所述业务数据包的近距离通信数据分组优先级(即PPPP)，使得选择的载波和/或BWP能够符合业务数据包的时延需求，提高传输性能。
在发送业务数据包时，通常还需要考虑可靠性(Reliability)的需求，R15(NR R15版本)主要是通过近距离通信数据分组可靠性(ProSe Per-Packet Reliability，PPPR)体现，终端的应用层为每个往下层的数据包提供一个PPPR，作为对可靠性需求的标识，如果从应用层发下来的数据包没有携带PPPR这个标识，说明该数据包无可靠性需求。本公开实施例中，在选择载波和/或BWP时，除了考虑业务数据包的通信范围之外，还可以考虑所述业务数据包的近距离通信数据分组可靠性(即PPPR)，使得选择的载波和/或BWP能够符合业务数据包的近距离通信数据分组可靠性需求，提高传输性能。
本公开实施例中，在选择载波和/或BWP时，除了考虑业务数据包的通信范围之外，还可以考虑无线数据发送参数(TxConfig)。所述无线数据发送参数包括以下参数中的至少一项：调制与编码策略(Modulation and Coding Scheme，MCS)；子信道数量(Subchannel Number)；重传数(RetxNumber)；发射功率(Tx Power)；以及，信道限制率(cr_Limit)。
本公开实施例中，在选择载波和/或BWP时，除了考虑业务数据包的通信范围之外，还可以考虑子载波间隔(Subcarrier spacing，SCS)。
本公开实施例中，在选择载波和/或BWP时，除了考虑业务数据包的通信范围之外，还可以考虑子帧长度。
本公开实施例中，传输资源对应的选择参数的配置信息可以由网络设备配置或预配置，或者由协议约定。
本公开实施例中，优选地，每一所述传输资源对应一所述配置信息。当然，也可以是多个传输资源对应一所述配置信息。
本公开实施例中，所述根据待发送业务数据包的选择参数的需求信息，以及传输资源对应的选择参数的配置信息，为所述业务数据包选择传输所用的所述传输资源的步骤包括：
根据待发送业务数据包的选择参数的需求信息，以及传输资源对应的选择参数的配置信息，选择满足所述业务数据包的选择参数的需求信息的所述传输资源；
当存在多个所述传输资源满足所述业务数据包的选择参数的需求信息时，根据预设规则从所述多个所述传输资源中选择一个传输资源。
优选地，所述预设规则包括以下规则中的至少一项：
根据所述传输资源的频段的高低，和/或，所述传输资源的信道拥塞率的大小，从多个所述传输资源中选择一个传输资源。
其中，当根据所述传输资源的频段的高低，从多个所述传输资源中选择一个传输资源时，优选地，从所述多个传输资源中选择频段最低的传输资源；选择频段最低的传输资源的原因在于：频率越低，传播损耗越小，覆盖距离越远；而且频率越低，绕射能力越强，建筑物内覆盖效果越好。
当根据所述传输资源的信道拥塞率的大小，从多个所述传输资源中选择一个传输资源。优选地，从所述多个传输资源中选择信道拥塞率最低的传输资源。
下面结合具体实施例，对本公开实施例中的副链路的传输资源选择方法进行说明。
在一具体实施例中，副链路的传输资源选择方法包括：

步骤22：根据待发送业务数据包的选择参数的需求信息，以及传输资源对应的选择参数的配置信息，选择满足所述业务数据包的选择参数的需求信息的所述传输资源；
举例来说，如果应用层下发的业务数据包携带Communication range的需求信息，且Communication range的需求信息中指示Communication range的需求为高时，可以选择Communication range为高的载波/BWP，例如表1中的carrier1/BWP1，或carrier2/BWP2。
如果应用层下发的业务数据包携带Communication range的需求信息和PPPP的需求信息，且Communication range的需求信息中指示Communication range的需求为中，PPPP的值为2时，可以选择Communication range为中、PPPP的值为2的载波/BWP，例如表1中的carrier3/BWP3。
如果应用层下发的业务数据包携带Communication range的需求信息，且Communication range的需求信息中指示Communication range的需求为低时，可以选择Communication range为低的载波/BWP，例如表1中的carrier4/BWP4。
步骤23：当存在多个所述传输资源满足所述业务数据包的选择参数的需求信息时，根据预设规则从所述多个所述传输资源中选择一个传输资源。
举例来说，如果应用层下发的业务数据包携带Communication range的需求信息，且Communication range的需求信息中指示Communication range的需求为高时，可以选择Communication range为高的载波/BWP，例如表1中的carrier1/BWP1和carrier2/BWP2都满足条件，此时，需要从carrier1/BWP1和carrier2/BWP2选择出一个。
具体地，根据载波/BWP的频段的高低，和/或，载波/BWP的信道拥塞率的大小，从符合条件的多个载波/BWP中选择一个载波/BWP。
本公开实施例中的副链路的传输资源选择方法可以应用LTE和NR sidelink通信系统，例如V2X通信系统，其中V2X用例例如包括自动排队驾驶(platooning)、半/全自动驾驶(advanced driving)、远程驾驶(Remote Driving)和支持扩展传感(Extended Sensors)。
