b.假设该旁链路资源抢占和/或信道接入失败,或者说监听到该旁链路资源繁忙。
UE2发送第二状态信息给控制节点。
1.例如如果此时采用的是FBE方法,则可以假设UE1 UE2该旁链路资源的监控结果是一样的,例如如果UE1判定该旁链路资源信道忙,则UE2也会判定该旁链路资源信道忙,因此可以由UE2来进行指示状态信息。
2.一种情况下,第二控制信息为NACK。
控制节点收到NACK后,可以指示新的PSCCH和/或PSSCH给UE1
3.一种情况下,第二控制信息指示了该旁链路资源抢占和/或信道接入失败。
控制节点收到该信息后,可以指示新的PSCCH和/或PSSCH给UE1。
例2:PSCCH和/或PSSCH成功和/或空闲。
控制节点调度节点指示PSCCH和/或PSSCH给UE1,UE1监听PSCCH和/或PSSCH对应的旁链路资源,并尝试进行抢占和/或信道接入。

1.例如如果此时采用的是FBE方法,则可以假设UE1 UE2该旁链路资源的监控结果是一样的,例如如果UE1判定该旁链路资源忙,则UE2也会判定该旁链路资源忙,因此可以由UE2来进行指示状态信息。
2.一种情况下,第二控制信息为ACK。
3.一种情况下,第二控制信息指示了该旁链路资源抢占和/或信道接入成功。
4.一种情况下,第二控制信息为该PSCCH和/或PSSCH对应的SL HARQ-ACK信息或对应的PSFCH上的信息。
如果SL HARQ-ACK或PSFCH上信息为NACK,说明尽管抢占成功,但是UE2却没有成功解码该消息,此时UE2发送NACK给控制节点,控制节点收到NACK后,可以指示新的PSCCH和/或PSSCH给UE1。
例3:PSCCH和/或PSSCH成功和/或空闲,PSFCH失败。
控制节点调度节点指示PSCCH和/或PSSCH和/或PSFCH给UE1,UE1监听PSCCH和/或PSSCH和/或PSFCH对应的旁链路资源,并尝试进行抢占和/或信道接入。
假设PSCCH和/或PSSCH对应的旁链路资源抢占和/或信道接入成功,或者说监听到PSCCH和/或PSSCH对应的旁链路资源空闲;但是PSFCH对应的旁链路资源抢占和/或信道接入失败,或者说PSFCH对应的旁链路资源繁忙。
UE1发送第二状态信息给控制节点。
1.一种情况下,第二控制信息为NACK。
2.一种情况下,第二控制信息指示了PSFCH对应的旁链路资源抢占和/或信道接入失败。
b.假设PSCCH和/或PSSCH对应的旁链路资源抢占和/或信道接入成功,或者说监听到PSCCH和/或PSSCH对应的旁链路资源空闲;但是PSFCH对应的旁链路资源抢占和/或信道接入失败,或者说PSFCH对应的旁链路资源繁忙。
UE2发送第二状态信息给控制节点。
1.例如如果此时采用的是FBE方法,则可以假设UE1 UE2该旁链路资源抢占和/或信道的监控结果是一样的,例如如果UE1判定该旁链路资源信道忙,则UE2也会判定该旁链路资源忙,因此可以由UE2来进行指示状态信息。
2.一种情况下,第二控制信息为NACK。
3.一种情况下,第二控制信息指示了PSFCH对应的旁链路资源抢占和/或信道接入失败。
进一步地,还指示了PSCCH和/或PSSCH对应的SL HARQ-ACK。
这样做的好处是:UE2直接告知了PSCCH和/或PSSCH解码是否成功,以及没有抢到PSFCH资源,在解码成功的情况下,基站可以不需要调度重传。
例4:拓展到用于两个mode2 UE之间。
1.UE3显示或隐式指示UE1旁链路资源。
a.通过PSCCH,SCI,PSFCH,preamble等中的至少一项指示信息。
例如,SCI指示了PSSCH资源,UE2需要在UE1发送的SCI指示的PSSCH上传输,但是在此之前需要先监控该资源是否空闲可用(即UE1发送类似1st SCI抢占信道并预留资源,UE2收到后按照SCI指示实际传输PSSCH)。
b.所述隐式指示可以是指示信息和旁链路资源之间存在对应关系。
例如,PSFCH和PSSCH资源存在对应关系,UE2需要在UE1发送的PSFCH对应的PSSCH资源上传输,但是在此之前需要先监控该资源是否空闲可用。
2.UE1按照指示信息进行监控和/或传输。
3.可选地,UE1和/或UE2将状态信息指示给UE3。
例5:
情况1.对于基于HARQ的TB传输,如果使用基于ACK-NACK的方法进行反馈。其中,所谓的基于ACK-NACK的方法是指解码成功时反馈ACK,失败时反馈NACK,那么,如果由于空闲信道评估(Clear Channel Assessment,CCA)或eCCA失败,UE无法使用部分或所有分配的资源或旁链路资源,则确定状态信息为NACK。
情况2.对于基于HARQ的TB传输,如果使用基于NACK-only的方法进行反馈。其中,所谓的基于NACK-only的方法是指解码成功时不反馈,失败时反馈NACK,那么,如果由于CCA或eCCA失败,UE无法使用部分或所有分配的资源或旁链路资源,则确定状态信息为NACK。
