在本申请一些实施例中,所述"协议"可以指通信领域的标准协议,例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议,本申请对此不做限定。
在NR系统中,终端设备按照一定时序关系进行传输,例如,若终端设备在时隙n上收到第一下行传输,第一下行传输可以调度时隙n+K上的第一上行传输。
以物理上行控制信道(Physical Uplink Control Channel,PUCCH)上传输混合自动请求重传-应答(Hybrid Automatic Repeat request Acknowledgement,HARQ-ACK)的传输时序为例进行说明。
对于PUCCH传输的时隙,如果一个物理下行共享信道(Physical Downlink Shared Channel,PDSCH)接收的结束位置在时隙n或一个指示半持续调度(Semi-Persistent Scheduling,SPS)PDSCH释放的物理下行控制信道(Physical Downlink Control Channel,PDCCH)接收的结束位置在时隙n,UE应在时隙n+K
1内的PUCCH资源上传输对应的HARQ-ACK信息,其中K
1是时隙个数并且是通过DCI格式中HARQ反馈时序指示(PDSCH-to-HARQ-timing-indicator)信息域来指示的,或是通过HARQ反馈时序集合(例如下行数据到上行确认(dl-DataToUL-ACK)参数)提供的。K
1=0对应PUCCH传输的最后一个时隙与PDSCH接收或指示SPS PDSCH释放的PDCCH接收的时隙重叠。
在上述示例中,第一下行传输为PDSCH接收或指示SPS PDSCH释放的PDCCH接收,第一上行传输为携带HARQ-ACK信息的传输,K用K
1表示。
当然,在NR系统中还有PDCCH调度的物理上行共享信道(Physical Uplink Shared channel,PUSCH)传输、PDCCH激活的配置授权物理上行共享信道(Configured Grant Physical Uplink Shared channel,PUSCH,CG-PUSCH)-PUSCH传输、随机接入响应(Random Access Response,RAR)或回退RAR(fallbackRAR)调度的PUSCH传输、成功RAR(successRAR)调度的PUCCH传输等传输时序,在此不再详述。
为了克服NTN系统中的大传输时延,或者,为了保证NTN系统正常工作,在NTN系统中引入偏移参数K
offset,并将该K
offset参数应用到相关的时序关系中。
也就是说,终端设备在时隙n上收到第一下行传输,第一下行传输可以调度时隙n+K+K
offset上的第一上行传输。
以上述PUCCH上传输HARQ-ACK的传输时序为例。对于结束位置在时隙n的PDSCH或指示SPS PDSCH释放的PDCCH,终端设备应在时隙n+K
1+K
offset内的PUCCH资源上传输对应的HARQ-ACK信息。
在NTN系统中,K
offset可以通过多种方式指示,此情况下,UE使用哪个K
offset计算上行传输的时序是一项亟需解决的问题。
