其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
参见图2,提供一种实施例的上行传输方法,可由终端设备执行,该方法包括:
步骤201:在承载了具有第一优先级的第一上行控制信息UCI和具有第二优先级的第二UCI的第一物理上行控制信道PUCCH与第二上行信道存在时域资源重叠的情况下,执行以下任一项:
根据第二上行信道或第二上行信道中的一个目标上行信道是否支持不同优先级复用进行上行传输;
在第二上行信道为多个物理上行共享信道PUSCH的情况下,在第二上行信道中分别确定用于承载第一UCI的第一目标PUSCH和用于承载第二UCI的第二目标PUSCH。
需要说明的是,第二上行信道可包括PUSCCH和PUSCH中的至少一种,在终端设备侧,传输可以是发送,在网络设备侧(例如,基站侧),传输可以 是接收,资源重叠可以理解为存在冲突。
在本实施例的上行传输方法中,在承载了不同优先级UCI的PUCCH与第二上行信道冲突的情况下,可根据第二上行信道是否支持不同优先级复用或者根据第二上行信道中的一个目标上行信道是否支持不同优先级复用来进行上行传输,或者,在承载了不同优先级UCI的PUCCH与第二上行信道冲突且第二上行信道为多个PUSCH冲突的情况下,可在冲突的PUSCH中分别确定用于承载不同优先级的UCI的目标PUSCH。也即是,在承载了具有不同优先级的UCI的PUCCH和第二上行信道存在冲突的情况下,根据第二上行信道或其中确定出的目标信道是否支持不同优先级复用的判定结果,确定如何解决冲突,或在第二上行信道中分别确定用于承载不同优先级的UCI的PUSCH,从而实现不同优先级的UCI分别的复用传输,以确保正常上行传输,提高上行传输性能。
在一个实施例中,根据第二上行信道或第二上行信道中的一个目标上行信道是否支持不同优先级复用进行上行传输,包括以下一项:
在第二上行信道为第二PUCCH的情况下,根据第二上行信道是否支持不同优先级复用进行上行传输;或
在第二上行信道为PUSCH的情况下,根据第二上行信道中的一个目标PUSCH是否支持不同优先级复用进行上行传输。
即在第二上行信道为PUCCH的情况下,可根据第二PUCCH是否支持不同优先级复用来进行上行传输,以提高上行传输的性能。在第二上行信道为PUSCH的情况下,可根据第二上行信道中的一个目标PUSCH是否支持不同优先级复用来进行上行传输,以提高上行传输的性能。
即在本实施例中,在承载了不同优先级UCI的PUCCH与第二PUCCH冲突的情况下,可根据第二PUCCH是否支持不同优先级复用来进行上行传输,在承载了不同优先级UCI的PUCCH与PUSCH冲突的情况下,可根据该PUSCH的一个目标PUSCH是否支持不同优先级复用来进行上行传输,以提高上行传输的性能。
在一个实施例中,在第二上行信道为第二PUCCH的情况下,根据第二上行信道是否支持不同优先级复用进行上行传输,包括以下一项:
在第二PUCCH支持不同优先级复用的情况下,对第一PUCCH以及第二PUCCH进行复用传输;或
在第二PUCCH不支持不同优先级复用的情况下,若第二PUCCH对应第一优先级,则丢弃第一PUCCH中的第二UCI,以及对第一PUCCH中的第一UCI与第二PUCCH进行复用传输,和/或,若第二PUCCH对应第二优先级,则丢弃第二PUCCH。
其中,丢弃即表示不需要发送,PUCCH上承载的UCI也随之丢弃。
即在本实施例中,在第二PUCCH支持不同优先级复用的情况下,可按照预定的复用规则,对第一PUCCH和第二PUCCH进行复用传输,即确定一个PUCCH资源,用于同时承载第一PUCCH上的第一UCI和第二UCI以及第二PUCCH上的UCI。其中,根据预定的复用规则,可能是第一UCI和第二UCI中的全部UCI都可以放在一个上行信道资源上进行同时传输,也可能因为PUCCH资源的承载容量有限,丢弃一部分UCI,这都是复用传输的范畴,下述类似解释,不再赘述。
在第二PUCCH不支持不同优先级复用的情况下,如果第二PUCCH对应第一优先级,则丢弃第一PUCCH中的第二UCI,按照预定的复用规则,将第一PUCCH中的第一UCI与第二PUCCH进行复用传输,即确定一个PUCCH资源,用于同时承载第一PUCCH上的第一UCI和第二PUCCH上的UCI;如果第二PUCCH对应第二优先级,则丢弃第二PUCCH,以避免第二PUCCH与第一PUCCH的冲突,提高传输稳定性。
在一个实施例中,在第二上行信道为PUSCH的情况下,根据第二上行信道中的一个目标PUSCH是否支持不同优先级复用进行上行传输,包括以下一项:
在目标PUSCH支持不同优先级复用的情况下,对第一PUCCH以及目标PUSCH进行复用传输;或
在目标PUSCH不支持不同优先级复用的情况下,若目标PUSCH对应第一优先级,则丢弃第一PUCCH中的第二UCI,以及对第一PUCCH中的第一UCI与目标PUSCH进行复用传输,和/或,若目标PUSCH对应第二优先级,则执行如下步骤:
丢弃目标PUSCH;
在丢弃目标PUSCH之后,在第二上行信道中还存在其他PUSCH与第一PUCCH在时域上存在重叠的情况下,则丢弃其他PUSCH,或者从其他PUSCH中选择一个PUSCH作为目标PUSCH,重复执行根据第二上行信道中的一个目标PUSCH是否支持不同优先级复用进行上行传输,直到不存在第一PDCCH和PUSCH的时域资源重叠。
在第二上行信道为PUSCH的情况下,可根据第二上行信道中的一个目标PUSCH是否支持不同优先级复用,进行上行传输,需要说明的是,目标PUSCH可以是按照预定的PUSCH选择规则,选择出的一个用于承载第一PUCCH上的UCI的PUSCH。
在目标PUSCH支持不同优先级复用的情况下,按照预定的复用规则,对第一PUCCH和目标PUSCH进行复用传输,即将第一PUCCH上的第一UCI和第二UCI或其中的部分(可以是第一UCI中的部分、第二UCI中的部分或第一UCI以及第二UCI整体中的部分)转移到目标PUSCH中进行上行传输;具体是所有UCI都转移还是不分UCI转移,部分被丢弃,是根据预定的复用规则确定的;例如,如果PUCCH上承载的UCI包含HARQ-ACK和CSI,且目标PUSCH上没有CSI,则可以将PUCCH上承载的全部UCI即HARQ-ACK和CSI都转移到PUSCH上传输,从而不传输PUCCH,而如果买不了PUSCH上存在CSI,因为已经存在了CSI不再需要传输PUCCH上的CSI,则只将PUCCH上的部分UCI即HARQ-ACK转移到目标PUSCH上传输,CSI则随着PUCCH被丢弃不传输;又例如,如果PUCCH上承载的UCI包含HARQ-ACK和SR,则因为SR不能在PUSCH上传输,只将PUCCH上承载的部分UCI即HARQ-ACK转移到PUSCH上传输,SR则随着PUCCH被丢弃不传输。
在目标PUSCH不支持不同优先级复用的情况下,如果目标PUSCH对应第一优先级,则丢弃第一PUCCH中的第二UCI,按照预定的复用规则,将第一PUCCH中的第一UCI与目标PUSCH进行复用传输,即将第一PUCCH上的第一UCI转移到目标PUSCH中进行上行传输;如果目标PUSCH对应第二优先级,则丢弃该目标PUSCH,进一步,如果还存在其他PUSCH(第二 上行信道中除去丢弃的PUSCH之外剩余的PUSCH)与第一PUCCH在时域上存在重叠,则丢弃其他PUSCH或在其他PUSCH中选择出一个目标PUSCH,即更新目标PUSCH,重复上述步骤,即重新根据目标PUSCH是否支持不同高优先级复用来进行上行传输的步骤,直到不存在第一PUCCH和PUSCH的时域资源重叠(即不存在冲突),如此,可提高上行传输的性能。
在一个实施例中,在第二上行信道为多个物理上行共享信道PUSCH的情况下,在第二上行信道中分别确定用于承载第一UCI的第一目标PUSCH和用于承载第二UCI的第二目标PUSCH,包括:
在第二上行信道中,确定具有第一优先级的第一PUSCH集合以及具有第二优先级的第二PUSCH集合;
在第一PUSCH集合中确定第一目标PUSCH;
在第二PUSCH集合中确定第二目标PUSCH。
即在本实施例中,可根据优先级将第二上行信道分为两个集合,分别在每个集合中确定一个目标PUSCH,即可确定第一目标PUSCH和第二目标PUSCH,第一目标PUSCH用于承载第一UCI,第二目标PUSCH用于承载第二UCI,也即是第一UCI在第一目标PUSCH上进行上行传输,第二UC在第二目标PUSCH上进行上行传输,提高上行传输性能。
在一个实施例中,方法还包括以下任一项:
第一PUSCH集合不为空集;
在第一PUSCH集合为空的情况下,丢弃第二上行信道;
在第一PUSCH集合为空的情况下,在第二PUSCH集合中确定支持不同优先级复用的第三PUSCH集合,从第三PUSCH集合中确定第一目标PUSCH。
可以理解,在第一PUSCH集合不为空集的情况下,总是可以在第一PUSCH集合中确定第一目标PUSCH,用于承载第一UCI,因此,一种实施情况下,基站和终端设备可以约定第一PUSCH集合不为空集,也就是终端设备不期待出现第一PUSCH集合是空集的情况,如果出现了,就属于错误调度或配置,没有具体的终端设备行为规定;当然,也可以不做约定第一PUSCH集合不能为空集,则在第一PUSCH集合为空集的情况下,本实施方法可丢弃第二上行信道,即丢弃所有与第一PUCCH重叠的PUSCH,避免 PUSCH与第一PUCCH的冲突,提高第一PUCCH传输性能;或者,在第一PUSCH集合为空的情况下,可在第二PUSCH集合中,进一步确定出支持不同优先级复用的第三PUSCH集合,从第三PUSCH集合中,根据预定的PUSCH选择规则,确定第一目标PUSCH,用于承载第一UCI。即在本实施例中,可根据第一PUSCH集合不同的情况,进行相应的不同的处理,实现不同的上行传输,提高上行传输性能的同时可提高传输灵活性。
在一个实施例中,方法还包括以下任一项:
第二PUSCH集合不为空集;
在第二PUSCH集合为空的情况下,或者在第二PUSCH集合为空且确定出第一目标PUSCH的情况下,丢弃第二UCI;
在二PUSCH集合为空且未确定出第一目标PUSCH的情况下,丢弃第二上行信道,在第一PUCCH上传输第一UCI和第二UCI。
可以理解,在第二PUSCH集合不为空集的情况下,总是可以在第二PUSCH集合中确定第二目标PUSCH,用于承载第二UCI,因此,一种实施情况下,基站和终端设备可以约定第二PUSCH集合不为空集,也就是终端设备不期待出现第二PUSCH集合是空集的情况,如果出现了,就属于错误调度或配置,没有具体的终端设备行为规定;当然,也可以不做约定第二PUSCH集合不能为空集,则在第二PUSCH集合为空集的情况下,或者在第二PUSCH集合为空且确定出第一目标PUSCH的情况下,可丢弃第二UCI,以减少冲突,提高第一PUCCH传输性能;或者,在第二PUSCH集合为空且未确定出第一目标PUSCH的情况下的情况下,可丢弃所有与第一PUCCH重叠的PUSCH,即丢弃第二上行信道,在第一PUCCH上传输第一UCI和第二UCI,避免第二上行信道与第一PUCCH的冲突,提高第一PUCCH传输性能。即在本实施例中,可根据第二PUSCH集合不同的情况,进行相应的不同的处理,实现不同的上行传输,提高上行传输性能的同时可提高传输灵活性。
在一个实施例中,方法还包括:
第三PUSCH集合不为空集;或,在第三PUSCH集合为空的情况下,丢弃第二上行信道,和/或,
在第三PUSCH集合不为空的情况下,在第二PUSCH集合中去掉从第三 PUSCH集合中确定出的第一目标PUSCH之后剩余的PUSCH中确定第二目标PUSCH。
可以理解,在第三PUSCH集合不为空集的情况下,总是可从第三PUSCH集合中确定第一目标PUSCH,用于承载第一UCI,因此,一种实施情况下,基站和终端设备可以约定第三PUSCH集合不为空集,也就是终端设备不期待出现第三PUSCH集合是空集的情况,如果出现了,就属于错误调度或配置,没有具体的终端设备行为规定;当然,也可以不做约定第三PUSCH集合不能为空集,则在第三PUSCH集合为空集的情况下,可丢弃所有与第一PUCCH重叠的PUSCH,即丢弃第二上行信道,避免第二上行信道与第一PUCCH的冲突,提高第一PUCCH传输性能;另外,在第三PUSCH集合不为空集的情况下,也可在第二PUSCH集合中去掉从第三PUSCH集合中确定出的第一目标PUSCH之后剩余的PUSCH中确定第二目标PUSCH,用于承载第二UCI,以确保上行传输性能。
在一个实施例中,在第二上行信道中分别确定用于承载第一UCI的第一目标PUSCH和用于承载第二UCI的第二目标PUSCH,包括:
在第二上行信道中,先确定一个目标PUSCH作为第一目标PUSCH或作为第二目标PUSCH;
在剩余的第二上行信道中,再确定另一个目标PUSCH作为第一目标PUSCH和第二目标PUSCH中的另一个。
即在本实施例中,可在第二上行信道中,先根据预定的PUSCH选择规则先确定一个目标PUSCH作为第一目标PUSCH和第二目标PUSCH中的一个,在剩余的第二上行信道(第一上行信道中除去该确定的一个目标PUSCH之外的上行信道)中,再根据预定的PUSCH选择规则确定出另一个目标PUSCH作为第一目标PUSCH和第二目标PUSCH中的另一个。例如,先确定一个目标PUSCH作为第一目标PUSCH,再在剩余的第二上行信道中确定另一个目标PUSCH作为第二目标PUSCH。又例如,先确定一个目标PUSCH作为第二目标PUSCH,再在剩余的第二上行信道中确定另一个目标PUSCH作为第一目标PUSCH,如此,确定的第一目标PUSCH和第二目标PUSCH不同,分别承载不同的UCI,提高上行传输性能。
在一个实施例中,方法还包括如下至少一项:
在第一目标PUSCH不能传输第一UCI的情况下:丢弃第二上行信道;
在第二目标PUSCH不能传输第二UCI的情况下:丢弃第二UCI,或者在第一目标PUSCH能传输第一UCI的情况下,丢弃第二UCI,或在第一目标PUSCH不能传输第一UCI的情况下,丢弃第二上行信道,在第一PUCCH上传输第一UCI和第二UCI。
一种实施情况下,终端设备和基站可以约定确定出的目标PUSCH一定可以传输对应的UCI,即终端设备可以不期待分别确定出的目标PUSCH不能传输对应的UCI,则做了这种约定,如果出现了确定出的目标PUSCH不能传输对应的UCI的情况,则属于错误调度或配置,不需要规定终端设备的传输行为;当然,也可以不做这个约定,则就可能会出现确定出的目标PUSCH不能传输对应的UCI的情况,此时如果出现不能传输的情况,对于第一目标PUSCH不能传输第一UCI的情况,可丢弃所有PUSCH,即丢弃第二上行信道;而对于第二目标PUSCH不能传输第二UCI的情况,可丢弃第二UCI,或者在第一目标PUSCH能传输第一UCI的情况下,丢弃第二UCI,或者如果第一目标PUSCH也不能传输第一UCI,则第一UCI和第二UCI可以在原PUCCH上传输,丢弃所有PUSCH,即丢弃第一上行信道,避免对第一PUCCH的冲突,提高传输性能。
在一个实施例中,在第二上行信道中分别确定用于承载第一UCI的第一目标PUSCH和用于承载第二UCI的第二目标PUSCH,包括:
根据第二上行信道的优先级以及是否支持不同优先级复用,将第二上行信道分为两个集合,分别在两个集合的每个集合中确定一个目标PUSCH。
即在本实施例中,可根据第二上行信道的优先级以及第二上行信道是否支持不同优先级复用,将第二上行信道为两个集合,分别在每个集合中确定一个目标PUSCH,从而实现用于承载第一UCI的第一目标PUSCH以及用于承载第二UCI的第二目标PUSCH的确定。可以理解,集合是根据优先级以及是否支持不同优先级复用来划分,第一目标PUSCH与第二目标PUSCH是在不同的集合中确定的PUSCH,用于承载不同的UCI,以提高传输性能。
在一个实施例中,根据第二上行信道的优先级以及是否支持不同优先级 复用,将第二上行信道分为两个集合,分别在两个集合的每个集合中确定一个目标PUSCH,包括:
确定具有第一优先级的PUSCH以及支持不同优先级复用的具有第二优先级的PUSCH作为第四PUSCH集合;
在第四PUSCH集合中,确定第一目标PUSCH用于承载第一PUCCH中的第一UCI。
即在本实施例中,确定具有第一优先级的PUSCH以及支持不同优先级复用的具有第二优先级的PUSCH作为第四PUSCH集合,可以理解,第四PUSCH集合中包括第二上行信道中具有第一优先级的PUSCH以及支持不同优先级复用的具有第二优先级的PUSCH,在第四PUSCH集合中,根据预定的PUSCH选择规则,确定第一目标PUSCH用于承载第一PUCCH上的第一UCI,确定的第一目标PUSCH具有第一优先级,或者支持不同优先级复用且具有第二优先级,用于承载第一UCI,以提高传输性能。
在一个实施例中,方法还包括以下任一项:
第四PUSCH集合不为空;
在第四PUSCH集合为空的情况下,丢弃第二上行信道。
在本实施例中,第四PUSCH集合可以不为空,在第四PUSCH集合不为空的情况下,可在第四PUSCH集合中,确定第一目标PUSCH用于承载第一PUCCH中的第一UCI,因此,一种实施情况下,基站和终端设备可以约定第四PUSCH集合不为空集,也就是终端设备不期待出现第四PUSCH集合是空集的情况,如果出现了,就属于错误调度或配置,没有具体的终端设备行为规定;当然,也可以不做约定第四PUSCH集合不能为空集,则在第四PUSCH集合为空的情况下,可丢弃所有与第一PUCCH重叠的PUSCH,即丢弃第二上行信道,避免第二上行信道对第一PUCCH的冲突,提高上行传输性能。
在一个实施例中,根据第二上行信道的优先级以及是否支持不同优先级复用,将第二上行信道分为两个集合,分别在两个集合的每个集合中确定一个目标PUSCH,包括:
确定具有第二优先级的PUSCH以及支持不同优先级复用的具有第一优先级的PUSCH作为第五PUSCH集合;
在确定的第一目标PUSCH在第五PUSCH集合中的情况下,将第五PUSCH集合中的第一目标PUSCH去掉;
在第五PUSCH集合中,确定第二目标PUSCH用于承载第一PUCCH中的第二UCI。
即在本实施例中,确定具有第二优先级的PUSCH以及支持不同优先级复用的具有第一优先级的PUSCH作为第五PUSCH集合,可以理解,第五PUSCH集合中包括第二上行信道中具有第二优先级的PUSCH以及支持不同优先级复用的具有第一优先级的PUSCH,可先去掉第五PUSCH集合中第一目标PUSCH去掉,根据预定的PUSCH选择规则,在去掉第一目标PUSCH的第五PUSCH集合中,确定第二目标PUSCH用于承载第一PUCCH上的第二UCI,确定的第二目标PUSCH具有第二优先级,或者支持不同优先级复用且具有第一优先级,用于承载第二UCI,以提高传输性能。
需要说明的是,第四PUSCH集合与第五PUSCH集合中可能存在重复的PUSCH。
在一个实施例中,方法还包括如下任一项:
第五PUSCH集合不为空;
在第五PUSCH集合为空且已确定出第一目标PUSCH的情况下,丢弃第二UCI;和/或,在第五PUSCH集合为空且未确定出第一目标PUSCH的情况下,丢弃第二上行信道,在第一PUCCH上传输第一UCI和第二UCI。
在本实施例中,第五PUSCH集合可以不为空,在第五PUSCH集合不为空的情况下,可在第五PUSCH集合中,确定第二目标PUSCH用于承载第一PUCCH中的第二UCI,因此,一种实施情况下,基站和终端设备可以约定第五PUSCH集合不为空集,也就是终端设备不期待出现第五PUSCH集合是空集的情况,如果出现了,就属于错误调度或配置,没有具体的终端设备行为规定;当然,也可以不做约定第五PUSCH集合不能为空集,则在第五PUSCH集合为空且已确定出第一目标PUSCH的情况下,可丢弃所有与第一PUCCH重叠的PUSCH,即丢弃第二上行信道,在第一PUCCH上传输第一UCI和第二UCI,避免第二上行信道对第一PUCCH的冲突,提高上行传输性能。
在一个实施例中,还包括如下至少一项:
在第二上行信道中包含PUSCH的情况下,PUSCH为不能与第一PUCCH并行传输的PUSCH;
第一PUCCH和/或第二上行信道支持通过PDCCH(Physical Downlink Control Channel,物理下行控制信道)中的指示域指示是否支持不同优先级复用;
第一优先级为高优先级,第二优先级为低优先级。
在本申请实施例方法中的PUSCH为不能与第一PUCCH并行传输的PUSCH,可以是终端设备(UE)不具有并行传输PUCCH和PUSCH的能力或终端设备具有并行传输PUCCH和PUSCH的能力但没有配置开启此功能,则任何一个PUSCH都不能与PUCCH并行传输;或,终端设备具有并行传输PUCCH和PUSCH的能力也配置开启了此功能,但PUCCH和PUSCH的组合不符合并行传输条件,如PUCCH和PUSCH为相同优先级,则不能并行传输,PUCCH和PUSCH为不同优先级且在同一个CC(Component Carrier,载波单元)或intra-band(带内跃迁)CC时不能并行传输,只有PUCCH和PUSCH具有不同的优先级且分别在inter-band的CC上时可以并行传输。
另外,在本实施例中,可通过PDCCH中的指示域指示第一PUCCH和/或第二上行信道是否支持不同优先级复用,在支持通过PDCCH中的指示域指示是否支持不同优先级复用的情况下,执行上述操作;指示PUCCH是否支持不同优先级复用的PDCCH为PUCCH对应的PDCCH,具体包括:调度PDSCH的PDCCH且PDSCH需要在PUCCH上进行HARQ-ACK(Hybrid Automatic Repeat request-ACKnowledgment,混合自动重传请求确认)反馈,或自身需要在PUCCH上进行HARQ-ACK反馈的PDCCH(如指示SPS(Semi-Persistent Scheduling,半持续调度)PDSCH(Physical Downlink Shared Channel,物理下行共享信道)资源释放的PDCCH、指示SCell dormancy(辅小区休眠)的PDCCH等);指示PUSCH是否支持不同优先级复用的PDCCH为调度PUSCH的PDCCH。
在一个实施例中,目标上行信道、第一目标PUSCH以及第二目标PUSCH可根据预定的PUSCH选择规则确定;
其中,预定的PUSCH选择规则包括以下至少一项:
PUSCH是否承载非周期CSI;
PUSCH所在载波的载波编号;
PUSCH是否具有对应的PDCCH;
PUSCH起始位置;
PUSCH的优先级;
PUSCH是否支持不同优先级复用。
例如,如果存在承载A-CSI(Aperiodic Channel State Information,非周期信道状态信息)的PUSCH,优先选择承载A-CSI的PUSCH,否则,如果同时存在具有PDCCH调度的PUSCH(DG(Dynamic Grant,动态许可)PUSCH)和没有PDCCH调度的PUSCH(CG(Configure Grant,配置许可)PUSCH,SP-CSI(semi-persistent Channel State Information,半持续信道状态信息)PUSCH等),优先选择DG PUSCH,按照上述规则选择了DG PUSCH或CG PUSCH(如果没有DG PUSCH)之后,如果多个载波上都有PUSCH,优先选择载波编号低的载波上的PUSCH,如果选择的载波上存在多个时域上不重叠的PUSCH与PUCCH重叠,选择最早的PUSCH,另外,还可以在这基础上,叠加对优先级的选择、对是否支持不同优先级复用的选择等。

下面以具体实施例对上述方法的过程加以具体说明,以网络设备为基站 为例。
目前,在5G NR(5 Generation New RAT,第五代新无线系统)Rel-17中,为了避免丢弃低优先级的信道上承载的HARQ-ACK带来的下行重传问题,可以支持低优先级的HARQ-ACK和高优先级的HARQ-ACK之间的复用传输。当存在时域资源重叠(即冲突)的上行信道中包含具有不同优先级的上行信道时,目前可能的执行方式为先处理具有相同优先级的上行信道之间的冲突,然后再处理具有不同优先级的上行信道的冲突。在处理具有不同优先级的上行信道的冲突时,会出现一个经过了不同优先级的PUCCH复用而得到的承载了高优先级和低优先级UCI的新的PUCCH资源,进一步与另一个PUCCH重叠,或进一步与PUSCH重叠,此时考虑到与新的PUCCH资源重叠的PUCCH或PUSCH可能并不支持不同优先级复用,目前还没有如何传输的方法。
表1为本公开中出现的英文缩写、英文全称和中文全称的对照表。

Figure PCTCN2023070969-appb-000001
Figure PCTCN2023070969-appb-000002
(1)5G NR中的UCI传输:
UCI包含HARQ-ACK,CSI,SR等信息。UCI在PUCCH上传输。其中,HARQ-ACK是ACK和NACK的统称,用于针对PDSCH或需要进行HARQ-ACK反馈的PDCCH(如指示SPS资源释放的PDCCH(又称SPS PDSCH release),指示SCell dormancy的PDCCH)进行反馈,告知基站PDSCH或需要进行HARQ-ACK反馈的PDCCH是否正确接收;CSI用于反馈下行传输的信道质量,从而帮助基站更好的进行下行调度,例如根据CSI进行MCS选择、配置适当的RB资源等;SR用于当终端设备有上行业务需要传输时, 向基站请求分配PUSCH传输资源,来进行上行业务传输。
HARQ-ACK可以基于不同的时间单元进行反馈,时间单元可以是时隙(slot)或子时隙(sub-slot)。子时隙是按照预定的子时隙长度将一个时隙固定划分为多个子单元,例如,一个子时隙长度为7个符号,可将一个包含14个符号的时隙划分为2个子时隙,又例如,一个子时隙长度为2个符号,可将一个包含14个符号的时隙划分为7个子时隙。当基于时隙进行反馈时,按照反馈时序n+k1确定承载HARQ-ACK的PUCCH传输所在时隙,其中,n为与需要进行HARQ-ACK反馈的下行传输(包括PDSCH和需要进行HARQ-ACK反馈的PDCCH)所在的时隙对应的参考上行时隙,k1为参考上行时隙与传输HARQ-ACK的目标时隙之间的时隙偏移值(即k1的单位是时隙);当基于子时隙进行反馈时,按照反馈时序n+k1确定承载HARQ-ACK的PUCCH传输所在子时隙,其中,n为与需要进行HARQ-ACK反馈的下行传输(包括PDSCH和需要进行HARQ-ACK反馈的PDCCH)所在的时隙对应的参考上行子时隙,k1为参考上行子时隙与传输HARQ-ACK的目标子时隙之间的子时隙偏移值(即k1的单位是子时隙)。承载HARQ-ACK的PUCCH资源不会跨域HARQ-ACK反馈所使用的时间单元,即如果基于子时隙传输,则承载HARQ-ACK的PUCCH不会超过子时隙边界,即不会跨越在多个子时隙中传输。
(2)相同优先级的PUCCH与PUCCH/PUSCH重叠
NR Rel-16中不支持PUCCH与PUSCH在同一时刻并行传输,不管是同一个载波还是不同载波上。当PUCCH和PUSCH(不做特殊说明,一般PUCCH和PUSCH指不使用重复传输的PUCCH和PUSCH)在时域资源上存在重叠时,在满足预定的时间线(timeline)的情况下,可以将UCI(一般是HARQ-ACK和CSI)从PUCCH上转移到一个PUSCH上传输,如果存在SR,则SR不在PUSCH上传输,SR被丢弃。如果存在多个PUSCH都与PUCCH重叠,则按照规则选择一个PUSCH。
其中,timeline的定义为:如果PUCCH或PUSCH具有对应的PDCCH时,例如PUCCH承载的HARQ-ACK为具有PDCCH调度的PDSCH的HARQ-ACK或为指示下行SPS资源释放的PDCCH的HARQ-ACK,则该调 度PDSCH的PDCCH或指示下行SPS资源释放的PDCCH为PUCCH对应的PDCCH,或者也可以称为调度PUCCH的PDCCH,调度PUSCH的PDCCH则为PUSCH对应的PDCCH,将重叠的PUCCH和PUSCH中的起始时间最早的信道的第一个符号作为目标符号,如果存在多个起始时刻相同的信道,则随便选一个信道,将其第一个符号作目标符号,目标符号需要满足如下timeline才能进行复用传输,否则认为是错误调度:
Timeline1:目标符号不早于在任何一个需要在PUCCH上进行HARQ-ACK反馈的PDSCH或SPS PDSCH release的最后一个符号之后的T1mux时间之后的第一个符号(包括CP在内的),即目标符号与任何一个上述PDSCH或SPS PDSCH release的最后一个符号之间的时间间隔不少于T1mux时间。T1mux与PDSCH的处理时延有关,可以根据预定的公式和相关的参数计算得到。该timeline的目的是保证在最终确定的传输HARQ-ACK的信道的传输开始之前,能够完成对HARQ-ACK的获取和准备。
Timeline2:目标符号不早于调度PDSCH(如果有)和PUSCH(如果有)的任意一个PDCCH(包括需要进行HARQ-ACK反馈的PDCCH)的最后一个符号之后的T2mux时间之后的第一个符号(包括CP在内的),即目标符号与任何一个上述PDCCH的最后一个符号之间的时间间隔不少于T2mux时间。T2mux与PUSCH的处理时延有关,可以根据预定的公式和相关的参数计算得到。该timeline的目的是保证当UCI需要转移到PUSCH上传输时,能够在PUCCH开始准备之前获得调度PUSCH的PDCCH,从而确定不需要在PUCCH上准备UCI传输,并且能够在PUSCH传输之前完成包括UCI在内的传输准备,即完成UCI的获取和复用处理,完成TB的准备(如编码、调制,加扰等操作);如果是多个PUCCH之间的复用,这个T2mux是用来模拟CSI和SR与HARQ-ACK复用的准备时间的。
如果PUCCH承载的HARQ-ACK没有对应的PDCCH(即HARQ-ACK为SPS PDSCH的HARQ-ACK),此时没有调度PDSCH的PDCCH,如果没有PUSCH或PUSCH也没有对应的PDCCH,则仅需要check T1mux不需要check T2mux。如果PUCCH上承载的是CSI和/或SR,因为没有对应的PDSCH,则不需要check T1mux,进一步如果没有PUSCH或PUSCH没有对应的 PDCCH,则也不需要check T2mux。
如果PUCCH和PUCCH重叠时,至少一个PUCCH是重复传输的(即占用多个时隙在每个时隙中重复性的传输UCI,也称多时隙传输),则仅针对重叠的repetition,按照传输高优先级,丢弃低优先级处理,不影响不存在重叠的repetition。如果PUCCH和重复传输的PUSCH重叠,当PUSCH采用基于时隙的重复传输时(R15重复传输,或R16repetition type A),PUCCH承载的UCI转移到和PUCCH重叠的一个或者多个PUSCH时隙中进行传输;当PUSCH采用R16repetition type B时,PUCCH承载的UCI转移到和PUCCH重叠的最早的一个包含大于1个符号的actual repetition PUSCH中传输(actual repetition即根据不可用符号、DL符号、时隙边界等进行分段之后得到的repetition PUSCH);上述与PUCCH重叠的一个或多个repetition的PUSCH都需要满足复用timeline。如果使用重复传输的PUCCH与使用或不使用重复传输的PUSCH重叠,则丢弃与PUCCH重叠的PUSCH,保证PUCCH的重复传输不被打断。
R17中根据UE能力可以支持inter-band(带间跃迁)CA(载波聚合)情况下不同载波上的PUCCH和PUSCH并行传输,但同一个载波上以及intra-band(带内跃迁)CA情况下暂不支持并行传输。
(3)不同物理层优先级的信道传输
一个UE可以支持不同的业务类型,如eMBB业务和URLLC业务等。不同的业务类型对可靠性和传输时延的需求不同。URLLC业务流可能是零散的不定时发生的,因此针对不同的业务独立预留不同的系统资源,在系统资源上的开销比较大,可能很多时候为URLLC预留的资源都是没有被使用的。为了提高系统资源利用率,可以支持不同业务在相同资源上复用传输。为了避免业务之间的相互影响,可以对不同的业务定义不同的优先级,从而在出现资源冲突的时候,区分哪些信道和信息更为重要。
PUCCH、PUSCH的物理层优先级可以通过默认方式、DCI动态指示或者RRC半静态配置的方式获得。例如,PUCCH在承载SR时,其优先级是通过其承载的SR对应的优先级确定的,而每个SR配置对应的优先级是高层信令配置的;PUCCH在承载SPS PDSCH的HARQ-ACK或承载指示SPS资 源释放的PDCCH(即SPS PDSCH release)的HARQ-ACK时,其优先级是通过高层信令为SPS PDSCH配置的HARQ-ACK码本编号来确定的,对应编号为0的HARQ-ACK码本为低优先级,对应编号为1的HARQ-ACK码本为高优先级;PUCCH在承载CSI(包括周期CSI和SP-CSI)时,其优先级默认为低优先级。当DCI中包含优先级指示域时,可以通过PUCCH、PUSCH对应的DCI(或PDCCH,本公开中PDCCH和DCI可以认为等价,DCI是PDCCH传输使用的具体格式,则具有对应的DCI等价于具有对应的PDCCH)中的优先级指示域获得优先级,即动态的优先级指示方式,例如,PDCCH调度一个PDSCH时,可以通过优先级指示域指示承载这个PDSCH的HARQ-ACK的PUCCH的优先级;PDCCH调度一个PUSCH时,可以通过优先级指示域指示被调度的PUSCH的优先级,其中,PUSCH包括仅承载TB的PUSCH或仅承载A-CSI的PUSCH或同时承载TB和A-CSI的PUSCH;对于承载SP-CSI的PUSCH,其优先级可以通过激活承载SP-CSI的PUSCH的DCI中的优先级指示域获得。如果DCI中不包含优先级指示域,或高层信令没有配置优先级,则默认为低优先级。
Rel-16中考虑到实现复杂度,并不支持具有不同物理层优先级的信道之间进行复用传输。当具有不同物理层优先级的信道发生冲突时,即多个PUCCH在同一个载波上在时域上存在重叠,或PUCCH和PUSCH在同一个载波或不同载波上在时域上存在重叠,或多个PUSCH在同一个载波上在时域上存在重叠时,丢弃低优先级的信道,只传输高优先级的信道。考虑到基于优先级的比较来停止低优先级的信道的发送需要一定的额外处理时间,进一步定义了停止低优先级信道的timeline:要求对应高优先级的信道的PDCCH与高优先级信道的起始符号之间的时间间隔不小于一个预定的T时间,这个T时间中考虑了原处理时延(例如T1proce、T2proce)和停止所需的时间(d1)。
Rel-17中,考虑到总是丢弃低优先级信道带来的系统效率下降的影响,例如总是丢弃低优先级HARQ-ACK,会导致低优先级HARQ-ACK对应的下行传输因无法及时获得反馈信息而进行冗余的重传,考虑支持具有不同物理层优先级的上行信道之间进行复用传输。目前已经支持当承载低优先级 HARQ-ACK的上行信道与承载高优先级HARQ-ACK的上行信道在时域资源上存在重叠时,可以将低优先级HARQ-ACK和高优先级HARQ-ACK按照特定规则放在同一个上行信道上进行传输,而不需要丢弃低优先级HARQ-ACK。当存在多个具有不同优先级的上行信道之间的冲突时,在R17中,支持具有不同优先级的信道进行复用传输,然而,在处理具有不同优先级的PUCCH的冲突时,可能得到一个承载了高优先级和低优先级UCI的新的PUCCH资源,这个PUCCH资源可能进一步与另一个PUCCH重叠,或进一步与PUSCH重叠,此时如果与新的PUCCH资源重叠的PUCCH或PUSCH不支持不同优先级复用,目前还没有如何传输的方法。基于此,本公开提供了一种上行传输方法,以提高上行传输性能。
实施例1(PUCCH之间的重叠):如图4所示的重叠情况,图中LP表示低优先级,HP表示高优先级,AN为HARQ-ACK的缩写,第一PUCCH为HP AN+LP AN即同时承载了HP AN和LP AN的PUCCH,其中HP AN为第一UCI,LP AN为第二UCI,第一优先级为HP,第二优先级为LP,第二上行信道为第二PUCCH,即承载HP SR(Scheduling Request,调度请求)的HP PUCCH。
终端设备侧:根据HP SR(第二PUCCH)是否支持不同优先级复用进行判断,假设不支持时,则因为第一PUCCH中存在LP AN,而此时不支持LP AN与HP SR复用,则确定丢弃LP AN,按照相同优先级的复用方式复用在同一个信道上进行传输,即确定一个PUCCH资源用于同时承载HP AN和HP SR,在这个资源上同时传输HP AN和HP SR(其中HP SR可能是显示传输,例如用X比特表示SR信息与AN一起进行编码传输,也可能是隐式传输,例如通过选择特定的资源或特定的循环移位来同时表达存在positive SR),如图5所示。假设支持时,直接将第一PUCCH和第二PUCCH上的所有UCI进行复用传输,即确定一个PUCCH资源用于同时承载HP AN、LP AN以及HP SR,在这个资源上同时传输HP AN、LP AN以及HP SR(HP SR的传输方式同上,不再赘述),如图6所示。
基站侧:采用与终端设备侧相同的方式确定一个PUCCH资源,在这个PUCCH资源上接收相应的UCI组合。
需要说明的,上述实施例1中,第一PUCCH为承载HP AN/HP SR+LP SR/LP CSI的PUCCH(假设支持HP AN/HP SR,与LP SR/LP CSI的复用传输,“/”表示和/或),第二PUCCH为承载HP SR的PUCCH,上述方式同样适用;第一PUCCH为承载HP AN+LP AN的PUCCH,第二PUCCH为承载LP SR/LP CSI的PUCCH,上述方式同样适用;第一PUCCH为承载HP SR+LP SR/LP CSI的PUCCH(假设支持HP AN和LP SR/LP CSI的复用传输,“/”表示和/或),第二PUCCH为承载HP SR/HP AN的PUCCH,上述方式同样适用;如果支持多个相同优先级的AN可以出现冲突,则第一PUCCH为承载HP AN/HP SR+LP AN/LP SR/LP CSI的PUCCH,第二PUCCH为承载LP AN,或LP AN与LP SR/LP CSI的组合PUCCH,上述方式同样适用,或者,第一PUCCH为承载HP AN/HP SR+LP AN/LP SR/LP CSI的PUCCH,第二PUCCH为承载HP AN/HP SR的PUCCH,上述方式同样适用。
实施例2(PUCCH与PUSCH之间的重叠):如图7所示的重叠情况,第一PUCCH为承载HP AN和LP AN的PUCCH,第二上行信道为PUSCH;其他描述同实施例1。
终端设备侧:先确定目标PUSCH,如果只有一个PUSCH与PUCCH重叠,则确定这个PUSCH为目标PUSCH;如果存在多个PUSCH与PUCCH重叠,则根据预定的PUSCH选择规则,确定出一个目标PUSCH,例如假设这两个PUSCH都不承载A-CSI且都具有PDCCH,则根据载波编号最小原则,选择LP PUSCH1为目标PUSCH,又例如根据优先选择高优先级,则在HP PUSCH3和HP PUSCH4中选择,假设这两个PUSCH都不承载A-CSI且都具有PDCCH,则根据载波编号最小原则,选择HP PUSCH3为目标PUSCH,不排除其他选择方式确定目标PUSCH。
再根据目标PUSCH是否支持不同优先级复用确定如何传输:假设确定支持时,将第一PUCCH上的HP AN和LP AN一起转移到目标PUSCH上进行传输;如图8所示(以选择的目标PUSCH为HP PUSCH3为例);其中,HP AN和LP AN在PUSCH上可以是独立编码或联合编码,如果是联合编码,则HP AN和LP AN看成整体,重用相关技术中AN在PUSCH上的传输方法,如果独立编码,则HP AN HP AN按照相关技术中AN在PUSCH上的传输方 式工作,LP AN按照相关技术中的CSI part1的传输方式工作;其中,如果高层信令对PUSCH配置了针对不同优先级的AN的资源偏移参数(beta-offset),则使用HP AN对应的资源偏移参数计算AN资源,使用LP AN对应的资源偏移参数计算AN资源,如果对一种UCI只配置了一种资源偏移参数,则不用区分优先级,HP AN和LP AN使用相同的对应AN的资源偏移参数计算资源,或者HP AN使用对应AN的资源偏移参数计算资源,LP AN使用CSI part1对应的资源偏移参数计算资源;假设确定不支持时,如果目标PUSCH为LP,则丢弃PUSCH,并进一步丢弃其他与PUCCH重叠的PUSCH,如图9中的第一种方式的结果,或对其他PUSCH重复上述确定目标PUSCH并判断的步骤,直到解决PUCCH和PUSCH的重叠,如图9中的第二中方式的结果(假设迭代选择之后确定了HP PUSCH3为目标PUSCH且PUSCH3支持不同优先级复用);如果目标PUSCH为HP,则丢弃第一PUCCH上的LP,即丢弃LP AN,将HP AN转移到目标PUSCH上传输,如图10所示。
基站侧:采用与终端设备侧相同的方式确定一个PUCCH资源,在这个PUCCH资源上接收相应的UCI组合;
需要说明的,对于实施例2,将承载HP AN和LP AN的PUCCH替换为承载其他HP和LP UCI组合的PUCCH,上述方法同样适用。
实施例3(方法2):如图7所示,其他解释同实施例1和2。
采用方式1:
终端设备侧:根据优先级将PUSCH分为两个集合,第一PUSCH集合为HP PUSCH3和HP PUSCH4,第二PUSCH集合为LP PUSCH1和LP PUSCH2;然后分别在第一PUSCH集合和第二PUSCH集合中,按照预定的PUSCH选择规则确定一个目标PUSCH;假设这些PUSCH都不承载A-CSI且都具有PDCCH,则根据载波编号最小原则,在第一PUSCH集合中选择HP PUSCH3用于承载PUCCH上的HP AN,在第二PUSCH集合中选择LP PUSCH1用于承载PUCCH上的LP AN,即UE将PUCCH上的HP AN转移到HP PUSCH3上传输,发送携带HP AN的HP PUSCH3,将LP AN转移到LP PUSCH1上传输,发送携带LP AN的LP PUSCH1,并丢弃PUCCH,其他PUSCH可以正常发送,如图11所示。
基站侧:采用与终端设备侧相同的方式,接收携带HP AN的HP PUSCH3,并从中获得HP AN,接收携带LP AN的LP PUSCH1,并从中获得LP AN,并在其他载波上接收其他PUSCH,不需要接收PUCCH;
采用方式2:
终端设备侧:在4个PUSCH中按照PUSCH选择规则,先选择一个PUSCH作为承载HP AN的第一目标PUSCH,再剩余的PUSCH中再选择一个PUSCH作为承载LP AN的第二目标PUSCH;假设PUSCH选择规则为优先选择与待承载的UCI具有相同优先级的PUSCH,并且在多个具有相同优先级的PUSCH中假设这些PUSCH都不承载A-CSI且都具有PDCCH,则根据载波编号最小原则选择,则对于HP AN,从HP PUSCH3和4中选择,从而确定HP PUSCH3为第一目标PUSCH,对于LP AN,从LP PUSCH1和2中选择,从而确定LP PUSCH1为第二目标PUSCH;即UE将PUCCH上的HP AN转移到HP PUSCH3上传输,发送携带HP AN的HP PUSCH3,将LP AN转移到LP PUSCH1上传输,发送携带LP AN的LP PUSCH1,并丢弃PUCCH,其他PUSCH可以正常发送,如图11所示。
基站侧:采用与终端设备侧相同的方式确定最终的传输结果,进行相应的接收即可;
采用方式3:
终端设备侧:假设LP PUSCH1支持不同优先级复用,LP PUSCH2不支持不同优先级复用,HP PUSCH3不支持不同优先级复用,HP PUSCH4支持不同优先级复用,则在进行PUSCH分组时,将LP PUSCH1与HP PUSCH3和4作为第四PUSCH集合,将HP PUSCH4和LP PUSCH1和2作为第五PUSCH集合;分别在两个PUSCH集合中确定目标PUSCH,假设确定目标PUSCH是不考虑优先级,假设这些PUSCH都不承载A-CSI且都具有PDCCH,则根据载波编号最小原则选择,在第四PUSCH集合中确定LP PUSCH1为第一目标PUSCH,由于LP PUSCH1也包含在第五集合中,则在第五集合中去掉LP PUSCH1之后根据选择规则确定目标PUSCH,则确定LP PUSCH2位第二目标PUSCH;即UE将PUCCH上的HP AN转移到LP PUSCH1上传输,发送携带HP AN的LP PUSCH1,将LP AN转移到LP PUSCH2上传输,发送 携带LP AN的LP PUSCH2,并丢弃PUCCH,其他PUSCH可以正常发送,如图12所示。
基站侧:采用与终端设备侧相同的方式确定最终的传输结果,进行相应的接收即可;
需要说明的,对于实施例3,将承载HP AN和LP AN的PUCCH替换为承载其他HP和LP UCI组合的PUCCH,上述方法同样适用。
需要说明的,上述PUCCH、PUSCH可以全部是通过动态的方式确定是否支持不同优先级复用的,所谓动态的方式即PUCCH或PUSCH具有对应的PDCCH(或grant)且PDCCH中包含指示是否支持不同优先级复用的指示域的情况,或者是部分是通过动态的方式确定是否支持不同优先级复用的,部分是通过半静态的方式确定是否支持不同优先级复用的,所谓半静态的方式即PUCCH或PUSCH是没有对应的PDCCH的,或者对应的PDCCH但其中没有指示是否支持不同优先级复用的指示域的情况,此时对应的PUCCH、PUSCH是否支持不同优先级复用可以是根据高层信令的配置确定,例如一个高层参数用于配置是否支持不同优先级复用传输,当配置为True时,认为任何上行信道都支持不同优先级复用传输,但配置为False或没有配置时认为任何上行信道都不支持不同优先级复用传输,或者对每一个上行信道有一个独立的高层参数配置是否支持不同优先级复用。上述实施例中HARQ-ACK为单播或多播的HARQ-ACK都适用。上述实施例中的时域资源重叠情况仅为示例,其中PUCCH可以与一个PUSCH在同一个载波上,也可以与所有PUSCH都在不同载波上,PUCCH和PUSCH之间的时域资源重叠可以是起始符号和/或结束符号对齐的,也可以是不对齐的,即full重叠和partial重叠。
在本公开的方案中,在承载了不同优先级UCI的PUCCH与其他PUCCH冲突的情况下,根据其他PUCCH是否支持不同优先级复用来确定是否能够直接进行PUCCH之间的复用还是丢弃低优先级的UCI之后进行复用;当承载了不同优先级UCI的PUCCH与PUSCH冲突时,根据PUSCH选择规则确的一个目标PUSCH是否支持不同优先级复用,进行上行传输,或者,在冲突的PUSCH中分别确定用于承载不同优先级的UCI的目标PUSCH。
即本公开给出了一种承载了具有不同优先级的UCI的PUCCH和其他上 行信道存在冲突时的上行传输方法,根据其他上行信道或其中确定出的目标信道是否支持不同优先级复用的判定结果,确定如何解决冲突,或在其他上行信道中分别确定用于承载不同优先级的UCI的PUSCH,从而实现不同优先级的UCI分别的复用传输,以解决冲突的问题,保证系统的正常传输。
