请参见图1,图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括通信设备11和网络侧设备12。其中,通信设备11也可以 称作通信设备或者用户通信设备(User Equipment,UE),通信设备11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant,PDA)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备等通信设备侧设备,需要说明的是,在本申请实施例中并不限定通信设备11的具体类型。网络侧设备12可以是基站或核心网,其中,上述基站可以是5G及以后版本的基站(例如:gNB、5G NR NB等),或者其他通信系统中的基站(例如:eNB、WLAN接入点、或其他接入点等),或者为位置服务器(例如:E-SMLC或LMF(Location Manager Function)),其中,基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例,但是本申请实施例并不限定基站的具体类型和具体通信系统。
新空口(New Radio,NR)旁链路(Sidelink,SL)资源分配方式有两种,一种基于基站调度(mode 1),另一种基于终端(User Equipment,UE)自主资源选择(mode 2)。此时资源信息可能来自基站的广播消息或者预配置的信息。UE如果工作在基站范围内并且与基站有无线资源控制(Radio Resource Control,RRC)连接,可以是mode1和/或mode2,UE如果工作在基站范围内但与基站没有RRC连接,只能工作在mode2。如果UE在基站范围外,那么只能工作在mode2,根据预配置的信息来进行V2X传输。对于mode 2,具体的工作方式如下:
1)数据发送端终端(TXUE)在资源选择被触发后,首先确定资源选择窗口。其中,资源选择窗口的下边界在资源选择触发后的T1时间,资源选择窗口的上边界在触发后的T2时间。
其中T2是UE在其传输块(Transport Block,TB)传输的数据时延(packet delay budget,PDB)内选择的值,T2不早于T1。
2)UE在资源选择之前,需要确定资源选择的备选资源集合(candidate resource set),根据资源选择窗口内的资源上的参考信号接收功率(Reference Signal Receiving Power,RSRP)测量值与相应的RSRP门限(threshold)做对比(RSRP和RSRP threshold不是直接在所述资源选择窗口内的资源上直接测量的,而是根据监听(sensing)结果确定的),如果RSRP高于RSRP threshold,那么对该资源进行资源排除,不能纳入备选资源集合,进行资源排除后资源选择窗口内剩余的资源组成备选资源集合。
备选资源集合中的资源在资源选择窗口中的资源的占比要不少于20%,如果少于x%(例如x=20/40/60),RSRP threshold需要按照步进值(3dB)进行增加,再进行所述资源排除操作,直到可以选出不少于所述x%的资源。
3)备选资源集合确定后,UE随机在备选资源集合中选择传输资源。另外,UE在本次传输可以为接下来的传输预留传输资源。
NR V2X支持链式的资源预留方式,也就是,一个旁链路控制信息(Sidelink Control Information,SCI)可以预留当前的资源,最多可以再额外预留两个资源,在下一个资源中,可以再指示两个预留资源。在资源选择窗口内,可以采用动态预留的方式持续预留资源。
在NR V2X中,受限于现有的资源分配方式,会出现一些传输可靠性不高的场景。例如在半双工的限制下一些UE不能监听到其他UE的预留信息,导致可靠性较低;由于隐藏节点的问题导致两个距离很近的UE的预留资源相同,导致资源碰撞,可靠性较低。
为了提高旁链路传输的可靠性,数据接收端终端(RX UE)可以向TX UE建议一些辅助信息,以辅助TX UE进行资源选择和/或调整TX UE的传输参数。例如辅助信息可以包括RX UE理想的接收资源信息,TX UE只在该资源上进行数据传输,或者优先选择该资源进行数据传输,以保证传输可靠性;或者辅助信息可以包括RX UE不理想的接收资源信息,TX UE在资源选择或者资源预留时需要排除这些资源。另外发送辅助信息的除了RX UE外,还可以是控制用户,纯辅助用户,控制节点等。
但是在组播场景中,如果组内的UE都向TX UE发送辅助信息,会带来巨大的信令开销,反而会降低数据传输的可靠性;另外如果多个RX UE都向 TX UE发送了辅助信息,TX UE如何根据这些辅助信息进行资源选择也会存在问题,因为每个RX UE的信道状态存在差异,导致它们在辅助信息中指示的资源也会存在较大的差异,最终导致TX UE根据收到的辅助信息选择的资源进行数据传输并不能得到可靠性的提升。组播场景下,在一个组内,任何数据接收端可以向数据发送端进行辅助信息的传输,如图2所示,左半侧的三个UE,即UE A、UE B和UE C为数据发送端,它们都能收到组内任意数据接收端(UE D、UE E和UE F)或者部分数据接收端发来的辅助信息,其中UE A和UE C收到的辅助信息来自于多个UE。
