可选地,第一目标资源集合包括的资源单元的大小与第二目标资源集合包括的资源单元的大小可以相同,或者,也可以不相同。
可选地,在本申请实施例中,终端接收网络设备发送的指示信息,所述指示信息用于指示所述第一下行信道对应的反馈时序为所述第二时间单元
可选地,在5G(NR,new radio)系统中,对于PDSCH支持动态指示反馈应答信息反馈时序(混合自动重传请求(Hybrid Automatic Repeat reQuest, HARQ)时序(timing))。即终端确定一个预配置的时序集合,该集合内可以包含8个值,例如,{K10,K11,K12,K13,K14,K15,K16,K17}。下行控制信息(Downlink Control Information,DCI)指示在时隙(slot)n中传输PDSCH,同时该DCI内包含3比特的目标信息域用于指示该时序集合中的一个值K1i,则终端在slot n+K1i内发送该PDSCH对应的肯定确认(Acknowledge,ACK)/否定确认(Non-Acknowledge,NACK)信息。
为了更加清楚地理解本申请,以下将结合图3进行举例说明。
如图3所示,在时隙n+1,n+2,n+4,n+5,n+6,n+8,n+9和n+11分别传输PDSCH1,PDSCH2,PDSCH3,PDSCH4,PDSCH5,PDSCH6,PDSCH7和PDSCH8。
其中,时隙n+8对应于时隙n至时隙n+7,也即时隙n+8上传输反馈信息,该反馈信息能够用于承载时隙n至时隙n+7上的下行信道的反馈应答信息。以及,时隙n+12对应于时隙n+4至时隙n+11,也即时隙n+12上传输反馈信息,该反馈信息能够用于承载时隙n+4至时隙n+11的下行信道的反馈应答信息。
从以上可以看出,对于时隙n+4至时隙n+7而言,其上传输的下行信道的反馈应答信息既可以承载与时隙n+8上,也可以承载在时隙n+12上。
网络设备可以指示反馈时序,例如,PDSCH 1、2、3、4、5的ACK/NACK在时隙n+8中传输,PDSCH 6、7、8的ACK/NACK在时隙n+12中传输。
则终端设备可以确定时隙n+8中的反馈信息序列为{0,b1,b2,0,b3,b4,b5,0},时隙n+12中的反馈信息序列为{0,0,0,0,b6,b7,0,b8},其中bi是PDSCHi对应的ACK/NACK信息,“0”为占位信息。
在本申请实施例中,该第一时间单元传输的第一反馈信息包括至少一个下行信道分别对应的至少一个反馈应答信息,该至少一个下行信道是通过第一目标资源集合中的资源单元传输的,且该至少一个下行信道对应的反馈时序是所述第一时间单元。
并且进一步地,所述第一目标资源集合中的每个资源单元在所述第一反馈信息中对应有至少一个比特,则该至少一个下行信道的反馈应答信息在所述反馈信息中的比特为传输该下行信道的资源单元对应的比特。
并且可选地,在第一目标资源集合中存在资源单元没有传输下行信道时,则该没有传输下行信道的资源单元对应的比特设置为占位信息。
并且可选地,在第一目标资源集合中存在资源单元传输的下行信道对应的反馈时序不是该第一时间单元时,则该资源单元对应的比特也设置为占位信息。
因此,在本申请实施例中,在一个资源单元的下行信道对应的反馈应答信息能够承载在多个时间单元时,在其中的一个时间单元上发送的反馈信息中针对该资源单元设置占位信息,可以避免重复传输反馈应答信息,可以提升物理上行控制信道(Physical Uplink Control Channel,PUCCH)的效率。
