(3)进行功率控制,即实现对该旁链路通信中的信息发送方即第一终端设备的发送功率的进一步调整,使得接收方即第二终端设备能够始终保证以较好的接收效果接收信息发送方发送的信息或信号,从而可以减少功率浪费、提升通信系统总体性能。此时,上述反馈信息可以包括混合式自动重传请求(Hybrid Automatic Repeat Request,HARQ)确认/失败(Acknowledgement/Negative Acknowledgement,ACK/NACK)、CQI、信噪比(Signal to Interference plus Noise Ratio,SINR)和块差错率(Block Error Rate,BLER)中的至少一种。

可选地,在本发明实施例的旁链路信息的传输方法中,上述反馈信息可以以下中的至少一个:
(1)CSI;则在反馈信息包括CSI时,可以达到获取SL信道状态的目的。
(2)基于相应的SL参考信息得到的测量结果;则在反馈信息包括相应的测量结果时,可以达到进行SL波束对准,确定SL发送波束和SL接收波束的目的。也就是说,在本发明实施例中,可以实现SL上的波束对准流程,解决因S-SSB发送受一定的事件触发限制,无法确定终端设备是否发送了S-SSB,从而无法基于S-SSB扫描实 现波束对准的问题。
(3)HARQACK/NACK、CQI、SINR和BLER中的至少一种;则在反馈信息包括前述信息时,可以达到进行功率控制的目的,即实现对该旁链路通信中的信息发送方即第一终端设备的发送功率的进一步调整,使得接收方即第二终端设备能够始终保证以较好的接收效果接收信息发送方发送的信息或信号,从而可以减少功率浪费、提升通信系统总体性能。
需要说明的是,上述反馈信息包括但不限于上述几项内容,还可以包括与SL波束管理、SL波束失败检测、SL波束失败恢复、设置准共址关系等相关的信息。
