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。无线通信系统包括终端11和网络侧设备12。其中,终端11也可以称作终端设备或者用户终端(User Equipment,UE),终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备,可穿戴式设备包括:手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网,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、发送接收点(Transmitting Receiving Point,TRP)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,但是并不限定基站的具体类型。
下面对本申请实施例涉及的相关通信术语进行说明。
(1)Sidelink HARQ反馈
为了提高Sidelink传输的可靠性和有效性,NR车联网(V2X)引入了Sidelink HARQ。在Sidelink上,发送终端(TX UE)向接收终端(RX UE)发送数据/TB,接收终端判断数据接收是否成功,如果接收成功,接收终端向发送节点反馈ACK,反之,反馈NACK。
Sidelink支持单播(unicast),组播(groupcast)和广播(broadcast)传输,其中unicast和groupcast传输需要支持Sidelink HARQ反馈。对于unicast传输,RX UE在其物理旁链路反馈信道(Pysical Sidelink feedback Channel,PSFCH)资源上反馈ACK/NACK。对于groupcast传输,反馈形式至少有两种,1)RX UE分享PSFCH资源,且RX UE只反馈NACK,对于TB解调成 功的情况,RX UE不做任何反馈;2)RX UE占用不同的PSFCH资源,RX UE在各自的资源上反馈ACK/NACK。
上述TB传输发生在物理旁链路共享信道(PSSCH)资源上,ACK/NACK传输发生在相应的PSFCH资源(corresponding PSFCH)上。
(2)Sidelink物理旁链路控制信道(Pysical Sidelink Control Channel,PSCCH)/PSSCH重传形式
Sidelink支持两种PSSCH重传形式,一种是基于HARQ反馈的传输或重传(HARQ feedback based retransmission),一种是盲重传(blind retransmission)。其中,如果TX UE采用基于HARQ反馈的传输或重传,RX UE需要对TX UE传输的PSSCH做HARQ反馈,TX UE根据HARQ反馈决定是否重传PSSCH;如果TX UE采用盲重传的重传方式,TX UE直接在重传资源上进行PSSCH传输,即不依赖于HARQ反馈。
对于一个TB的多个传输资源,不支持在不同的传输资源上分别进行盲重传和基于HARQ反馈的传输或重传。例如,一个用户获取了2个传输资源,打算用于某个TB的重传,这2个传输资源要么都盲重传,要么都进行基于HARQ反馈的传输或重传。对于一个TB的传输,如果该TB的初传或者某次重传对应的HARQ反馈状态为ACK,或者,用户判断该传输成功,则用户释放预留给该TB的其他传输资源。
(3)Sidelink的资源选择
Sidelink的资源分配方式至少有模式1(mode 1)和模式2(mode 2)两种模式。针对mode 1,控制节点会为TX UE分配传输资源,针对mode 2,TXUE进行自主选择传输资源。
至少针对mode 2,为了保证PSSCH重传的资源出现在TX UE解调反馈信息之后,规定任意两次选择的PSSCH传输资源间的时间间隔需要大于HARQ往返时间(Round Trip Time,RTT)。
HARQ RTT时间Z=a+b,其中:
a是第一个PSSCH传输的最后一个符号的结束和相应PSFCH接收的第一个符号的开始之间的时间间隔,a由资源池配置和MinTimeGapPSFCH和periodPSFCHresource的更高层参数确定;
b是PSFCH接收和处理重传准备所需的时间,包括必要物理信道的多路复用和任何TX-RX/RX-TX切换时间,由UE实现确定。
请参考图2和图3,图2和图3为用于确定HARQ RTT时间的a和b的示意图。图2中,b值较小,PSFCH接收和处理重传准备能够在PSFCH所在时隙(slot)内完成。图3中,b值较大,PSFCH接收和处理重传准备需要跨slot。
(4)Sidelink的资源预留
TX UE会对其分配的资源进行资源预留,预留分为周期性预留和非周期性预留,预留资源为以后的PSSCH和/或PSCCH传输所用。其预留周期(reservation period)可以在旁链路控制信息中进行指示,旁链路控制信息可以是(Sidelink Control Information,SCI)、SFCI、SL MAC CE、PC5-RRC、其他旁链路信道或者信号中的至少一项。
用户从控制节点获取资源时(例如控制节点为用户分配或者指示或者推荐资源,典型地,例如mode 1的情况下),控制节点提供的相邻两次的传输资源(例如:PSSCH和/或PSCCH资源)可能不满足HARQ RTT时间,如图4和图5所示。对于图4的情况,(对应同一个TB的)相邻两个传输资源对应到同一个PSFCH时机(occasion)。对于图5的情况,虽然(对应同一个TB的)相邻的两个传输资源对应到不同的PSFCH时机,但是TX UE处理前一次传输资源和/或其对应的PSFCH所需时间较长,在下一次PSSCH传输资源到来时,无法为PSSCH重传做出准备。图4为常规情况,但不排除图5所示的情况出现的可能。
下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的旁链路传输方法、传输装置和终端进行详细地说明。

下面分别对旁链路控制信令中的各指示信息确定方法进行说明。
(一)旁链路控制信令中的资源指示信息的确定方式
1)旁链路控制信令中的资源指示信息根据旁链路资源控制信令中的资源指示信息确定
在本申请的一些实施例中,可选的,所述旁链路控制信令中的指示信息根据旁链路资源控制信令中的指示信息确定:
所述旁链路控制信令中的资源指示信息所指示的传输资源与所述旁链路资源控制信令中的资源指示信息所指示的传输资源相同;例如:SCI中资源指示信息和SL DCI中资源指示信息内容相同或指示的资源相同。
可选的,所述旁链路控制信令中的资源指示信息指示当前传输资源和当前传输资源之后的传输资源;
当前传输资源也可以描述为旁链路控制信令所在的(或调度的)传输资源,或者,旁链路控制信令调度或指示的数据所在的传输资源,或者,旁链路控制信令和旁链路控制信令调度或指示的数据所在的传输资源。
本申请实施例中,可以通过直接或间接指示N=1,来指示当前传输资源,N为指示的传输资源的个数。例如将SCI中的时域资源指示信息(Time Resource indicator value,TRIV))设置为0,表示N=1。例如将SCI中的TRIV设置为0,表示SCI指示当前传输资源。
传输资源可以为PSCCH和/或PSSCH资源。
其中,当前传输资源和当前传输资源之后的传输资源均为同一个目标传输资源内的传输资源。
例如:SL CG包含传输资源1、2和3,传输资源1、2和3上SCI中的资源指示信息分别指示:传输资源1和2和3,传输资源2和3,传输资源3。
可选的,旁链路控制信令中的资源指示信息指示的当前传输资源和当前传输资源之后的传输资源的总数不超过预设阈值;
例如:预设阈值Nmax=2,SL CG包含传输资源1、2和3,传输资源1、2和3上SCI中的资源指示信息分别指示了:传输资源1和2,传输资源2和3,传输资源3。
或者,所述旁链路控制信令中的资源指示信息指示的当前传输资源和当前传输资源之后的传输资源的总数,不超过第一数值和所述预设阈值中的最小值,所述第一数值为包含当前传输资源以及其之后的可用传输资源的总数。
可选的,所述旁链路控制信令中的指示信息指示目标传输资源内的一个传输资源。
其中,所述旁链路控制信令中的指示信息指示目标传输资源内的一个传输资源,即,所述旁链路控制信令中的资源指示信息指示目标传输资源内的一个传输资源。
2)旁链路控制信令中的资源指示信息指示目标传输资源内的一个传输资源
在本申请的一些实施例中,所述旁链路控制信令中的资源指示信息指示目标传输资源内的一个传输资源,旁链路控制信令中的资源指示信息不依赖于旁链路资源控制信令中的资源指示信息。
下面对上述实施例1)和2)中,旁链路控制信令中的资源指示信息指示目标传输资源内的一个传输资源的情况进行说明。
本申请的实施例1)和2)中,可选的,所述旁链路控制信令中的指示信息指示目标传输资源内的一个传输资源包括:所述目标传输资源内的两个传输资源或两个传输资源组之间满足目标间隔要求或者所述目标传输资源内的两个传输资源或两个传输资源组之间不满足目标间隔要求时,所述旁链路控制信令中的指示信息指示目标传输资源内的一个传输资源。
本申请的实施例1)和2)中,可选的,所述旁链路控制信令中的指示信息指示目标传输资源内的一个传输资源包括:若所述目标传输资源内的两个传输资源或两个传输资源组之间不满足目标间隔要求,所述旁链路控制信令中的指示信息指示目标传输资源内的一个传输资源。
请参考图7和图8,图7中,旁链路资源控制信令(DCI)提供了两个传输资源,第一个传输资源指示自身,并指示了第二个传输资源,该种情况下,若第一个传输资源和第二传输资源之间不满足目标间隔要求,在第二个PSSCH传输资源到来时,无法为PSSCH重传做出准备。而,本申请实施例中,如图8所示,若所述目标传输资源内的两个传输资源或两个传输资源组之间不满足目标间隔要求,第一个传输资源和第二个传输资源均指示自身,此时每次传输都只指示当前传输资源,即不进行资源预留,从而不需要考虑下一个资源和当前资源之间是否满足目标间隔要求的问题。
下面对两个传输资源或两个传输资源组的含义进行说明。
本申请实施例中,可选的,所述两个传输资源为目标传输资源中的两个 传输资源;所述两个传输资源组为目标传输资源中的两个传输资源组。
本申请实施例中,进一步可选的,所述两个传输资源为目标传输资源中的相邻的两个传输资源,或者,为目标传输资源中的任意两个传输资源,或者,为目标传输资源中的预设的两个传输资源。预设的两个传输资源可以是目标传输资源中的最早两个传输资源,最晚两个传输资源,对应预设编号或者位置的两个传输资源。
所述两个传输资源组为目标传输资源中的相邻的两个传输资源组,或者,为目标传输资源中的任意两个传输资源组,或者,为目标传输资源中的预设的两个传输资源组。预设的两个传输资源组可以是目标传输资源中的最早两个传输资源组,最晚两个传输资源组,对应预设编号或者位置的两个传输资源组。其中,目标传输资源中的相邻的两个传输资源或传输资源组之间的间隔满足或不满足目标间隔要求可以理解为:目标传输资源中所有相邻的两个传输资源或传输资源组之间的间隔都满足或不满足目标间隔要求,或者目标传输资源中至少存在两个相邻的传输资源或传输资源组之间的间隔满足或不满足目标间隔要求。
目标传输资源中的任意的两个传输资源或传输资源组之间的间隔满足或不满足目标间隔要求可以理解为:目标传输资源中所有两个传输资源或传输资源组之间的间隔都满足或不满足目标间隔要求,或者目标传输资源中至少存在两个传输资源或传输资源组之间的间隔满足或不满足目标间隔要求。

本申请实施例中,可选的,I=J。
本申请实施例中,可选的,所述两个传输资源组为针对同一个TB的传输的传输资源组。
本申请实施例中,可选的,所述两个传输资源组为同一个旁链路配置授权的具有相同HARQ进程(process)ID的传输资源组;或者,所述两个传输资源组为同一个旁链路配置授权的相邻两个周期的传输资源组。
本申请实施例中,设置传输资源组的好处在于:不需要考虑一个SL DCI或者一个SL CG内的多个传输资源之间是否需要满足目标间隔要求,是否出现混杂(mixed)盲重传和基于HARQ反馈的传输或重传的问题。
其中,目标传输资源中的相邻的两个传输资源或传输资源组之间的间隔满足或不满足目标间隔要求可以理解为:目标传输资源中所有相邻的两个传输资源或传输资源组之间的间隔都满足或不满足目标间隔要求,或者目标传输资源中至少存在两个相邻的传输资源或传输资源组之间的间隔满足或不满足目标间隔要求。
