Description

副链路的连接控制方法、终端及网络侧设备
相关申请的交叉引用
本申请主张在2018年11月1日在中国提交的中国专利申请No.201811297562.1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,尤其是指一种副链路的连接控制方法、终端及网络侧设备。
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副链路(sidelink,或译为侧链路,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。
LTE sidelink的设计适用于特定的公共安全事务(如火灾场所或地震等灾难场所进行紧急通讯),或车联网(vehicle to everything,V2X)通信等。车联网通信包括各种业务,例如,基本安全类通信,高级(自动)驾驶,编队,传感器扩展等等。由于LTE sidelink只支持广播通信,因此主要用于基本安全类通信,其他在时延、可靠性方面具有严格服务质量(Quality of Service,QoS)需求的高级V2X业务将通过新空口(New Radio,NR)sidelink支持。
第五代(5-th Generation,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,但目前版本的NR系统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。
NR sidelink将支持单播(unicast)、组播(groupcast)以及广播(broadcast)等多种传输模式(transmission type),并支持单播及组播模式下的混合自动选择重传(Hybrid Automatic Repeat Request,HARQ)。
此外,NR sidelink还支持多种资源分配模式,例如基站调度模式(也称之为mode 1),终端自主资源选择模式或终端调度其他终端(也称之为mode 2)等等。
在NR V2X高密度场景下,考虑基站和终端处理能力是有限的,因此需要对mode1和mode 2下的终端进行接入控制避免拥塞。尤其对于单播和组播业务,发送端终端和一个或多个接收端终端建立维护点对点的连接,需要占用大量的空口资源,拥塞更易发生。目前的研究中,还没有对mode1或mode2下的终端进行接入控制避免拥塞的方案。
发明内容
本公开实施例提供一种sidelink的连接控制方法、终端及网络侧设备,以解决相关技术中没有解决终端的sidelink接入拥塞的方案的问题。
为了解决上述技术问题,本公开是这样实现的:一种副链路sidelink的连接控制方法,应用于第一终端,包括:

本公开实施例还提供了一种副链路sidelink的连接控制方法,应用于第二终端,包括:
发送用于指示第一终端的sidelink连接行为的接入控制参数。
本公开实施例还提供了一种副链路sidelink的连接控制方法,应用于终端,包括:
获取网络侧设备发送或网络预配置的sidelink资源池的配置参数,所述配置参数用于指示至少一个sidelink资源池以及与每个所述sidelink资源池关联的以下至少一项信息:

至少一套服务质量QoS参数;
