具体地,本公开实施例提供了一种UCI的处理方法,解决了相关技术中针对承载不同业务的UCI的PUCCH资源在时域上重叠时,还没有具体的传输方案的问题。
第一实施例
如图1所示,本公开的实施例提供了一种UCI的处理方法,应用于终端,具体包括以下步骤:
步骤11:当承载第一UCI的第一PUCCH资源与承载第二UCI的第二PUCCH资源在时域上不重叠,所述第一PUCCH资源与承载第三UCI的第三PUCCH资源在时域上不重叠,且所述第二PUCCH资源和所述第三PUCCH资源在时域上重叠时:若用于同时传输所述第二UCI和所述第三UCI的第四PUCCH资源与所述第一PUCCH资源重叠,则丢弃第一目标UCI;其中,所述第一目标UCI为第二UCI与所述第三UCI中的一个。
具体地,当承载第一UCI的第一PUCCH资源与承载第二UCI的第二PUCCH资源在时域上不重叠,所述第一PUCCH资源与承载第三UCI的第三PUCCH资源在时域上不重叠,且所述第二PUCCH资源和所述第三PUCCH资源在时域上重叠时:若用于同时传输所述第二UCI和所述第三UCI的第四PUCCH资源与所述第一PUCCH资源重叠,则丢弃第一目标UCI,并在第一PUCCH资源上传输所述第一UCI,以及在第二目标UCI对应的PUCCH资源上传输第二目标UCI;其中,所述第一目标UCI为第二UCI与所述第三UCI中的一个,所述第二目标UCI为第二UCI与所述第三UCI中除所述第一目标UCI的另一个。

步骤21:当所述第一PUCCH资源与所述第二PUCCH资源在时域上不重叠,所述第一PUCCH资源与所述第三PUCCH资源在时域上不重叠,且所述第二PUCCH资源和所述第三PUCCH资源在时域上重叠时:根据预先定义的复用传输规则,确定用于同时传输所述第二UCI和所述第三UCI的第四PUCCH资源。
可选地,根据预先定义的复用传输规则,确定用于同时传输第二UCI和第三UCI的第四PUCCH资源还可以具体包括:根据所述第二UCI的类型和/或传输所述第二UCI所使用的PUCCH格式,以及所述第三UCI的类型和/或传输所述第三UCI的所使用的PUCCH格式,确定所述用于同时传输第二UCI和第三UCI的第四PUCCH资源。
其中,所述第四PUCCH资源为:所述第二PUCCH资源,或者所述第三 PUCCH资源,或者不同于所述第二PUCCH资源和所述第三PUCCH资源的PUCCH资源。
其中,在NR系统中,定义了NR PUCCH格式(format)0、1、2、3、4共5种PUCCH格式,其中,PUCCH格式0和1可以承载1~2比特UCI传输,PUCCH格式2、3和4可以承载大于2比特UCI传输。
HARQ-ACK信息可以使用这5种PUCCH格式中的任何一种进行传输:基站可以为终端配置至少一个PUCCH资源集合,一个PUCCH资源集合可以包含多个PUCCH资源,不同的PUCCH资源可以对应相同或者不同的PUCCH格式。
如果仅配置了一个PUCCH资源集合,该集合中仅包含PUCCH格式0,1资源,因此,只能用于1~2比特HARQ-ACK信息的传输。
如果配置了超过一个PUCCH资源集合,则不同的PUCCH资源集合可以对应不同的UCI比特数范围,终端可以根据HARQ-ACK信息的比特数(如果有其他UCI与HARQ-ACK复用,则是所有UCI的总比特数)在多个PUCCH资源集合中选择一个,然后根据HARQ-ACK对应的物理下行控制信道(Physical Downlink Control Channel,PDCCH)中的PUCCH资源指示域,在确定的PUCCH资源集合中确定一个PUCCH资源,用于HARQ-ACK信息(或与其他UCI复用在一起)的传输。其中,在HARQ-ACK信息为物理下行控制信道(Physical Downlink Shared Channel,PDSCH)的反馈信息时,PDCCH是调度PDSCH的PDCCH;或者,在HARQ-ACK信息为指示下行半持续调度(Semi-Persistent Scheduling,SPS)资源释放的PDCCH的反馈信息时,PDCCH是下行SPS资源释放的PDCCH本身。
对于没有对应的PDCCH的HARQ-ACK信息,即承载SPS HARQ-ACK信息(即对应SPS PDSCH的HARQ-ACK信息),由于一个SPS HARQ-ACK信息仅为1比特,可以使用PUCCH格式0或1,在高层信令配置的1个PUCCH资源上传输。调度请求(Scheduling Request,SR)信息可以使用PUCCH格式0或1,在高层信令配置的一个PUCCH资源上传输。周期信道状态信息(Channel State Information,CSI)可以配置使用PUCCH格式2或3或4,在高层信令配置的一个PUCCH资源上传输。
以下结合具体场景,针对根据预先定义的复用传输规则,确定用于同时传输第二UCI和第三UCI的第四PUCCH资源进行具体说明:
在NR系统中,承载UCI的PUCCH资源基于时隙进行传输,即可以将一个时隙中任何的上行符号分配给PUCCH资源进行传输。当出现承载不同UCI的PUCCH资源之间在时域上重叠时,根据如下的方法确定用于同时传输第二UCI和第三UCI的第四PUCCH资源(对于HARQ-ACK信息和CSI的复用传输前提是配置了允许HARQ-ACK信息和CSI同时传输,否则,丢弃CSI):
场景一:当承载SR信息的PUCCH资源与承载HARQ-ACK信息的PUCCH资源在时域上重叠,且承载HARQ-ACK信息的PUCCH资源使用PUCCH格式0(承载SR的PUCCH资源可以使用PUCCH格式0也可以使用PUCCH格式1)时,确定承载HARQ-ACK信息的PUCCH资源为用于同时传输HARQ-ACK信息和SR信息的第四PUCCH资源。
场景二:当承载SR信息的PUCCH资源与承载HARQ-ACK信息的PUCCH资源在时域上重叠,且承载SR信息的PUCCH资源使用PUCCH格式0,承载HARQ-ACK信息的PUCCH资源使用PUCCH格式1时,丢弃(drop)SR信息,即此时不进行复用传输。
场景三:当承载SR信息的PUCCH资源与承载HARQ-ACK信息的PUCCH资源在时域上重叠,且承载SR信息的PUCCH资源使用PUCCH格式1,承载HARQ-ACK信息的PUCCH资源使用PUCCH格式1时,当存在正(positive)SR时,确定承载SR信息的PUCCH资源为用于同时传输HARQ-ACK信息和SR信息的PUCCH资源。
场景四:当承载SR信息的PUCCH资源与承载HARQ-ACK信息的PUCCH资源在时域上重叠,且承载HARQ-ACK信息的PUCCH资源使用PUCCH格式2或3或4时(承载SR信息的PUCCH资源可以使用PUCCH格式0也可以使用PUCCH格式1)时,根据SR信息和HARQ-ACK信息的总比特数确定一个PUCCH资源集合,根据HARQ-ACK信息对应的下行控制信息(Downlink Control Information,DCI)中的PUCCH资源指示域,在确定的一个PUCCH资源集合中确定一个PUCCH资源,用于同时传输SR信息 和HARQ-ACK信息。
其中,SR信息为X比特,表示与HARQ-ACK信息重叠的X个SR信息中的SR状态(哪个为正,或者都为负),即不论SR的状态为positive还是负(negative),总是要传输X比特SR信息,以避免由于SR状态导致HARQ-ACK信息的PUCCH资源上传输的UCI比特数的变化。
场景五:当承载SPS HARQ-ACK信息(即对应SPS PDSCH的HARQ-ACK,也即没有对应的PDCCH的HARQ-ACK)和/或SR信息的PUCCH资源,与承载CSI的PUCCH资源在时域上重叠时,则确定CSI对应的PUCCH资源为用于同时传输SPS HARQ-ACK信息和/或SR信息与CSI的PUCCH资源。
场景六:当承载有对应的PDCCH(即当HARQ-ACK信息为PDSCH的反馈信息时,调度PDSCH的PDCCH资源与HARQ-ACK信息对应;当HARQ-ACK信息为指示下行SPS资源释放的PDCCH的反馈信息时,该PDCCH资源与HARQ-ACK信息对应)的HARQ-ACK信息的PUCCH资源与承载CSI的PUCCH资源在时域上重叠时,根据HARQ-ACK信息和CSI信息的总比特数,在多个PUCCH资源集合中选择一个PUCCH资源集合,再根据HARQ-ACK信息对应的DCI中的PUCCH资源指示域从选择的一个PUCCH资源集合中确定出一个PUCCH资源,用于同时承载HARQ-ACK信息和CSI。
此时重新确定的PUCCH资源与原承载HARQ-ACK信息的PUCCH资源可能相同或者不同(如果不同,即为一个新的PUCCH资源)。终端不期待仅被配置了一个PUCCH资源集合时被配置支持HARQ-ACK和CSI同时传输。
当一个时隙中存在多个PUCCH资源,且存在PUCCH资源之间在时域上的重叠时:若一个时隙中的PUCCH资源构成集合Q,确定该集合Q中起始时间最早的上行信道作为信道A,确定与信道A在时域上存在重叠的信道集合X;对信道A和信道X上的UCI按照上述复用传输规则得到一个用于复用传输的信道资源,用这个复用传输的信道资源替换集合Q中的信道A和信道X,继续上述步骤在新的Q集合中确定信道A和信道X,以此类推,直到得到多个时域上不重叠的PUCCH。
可选地,根据预先定义的复用传输规则,确定用于同时传输第二UCI和第三UCI的第四PUCCH资源可以具体包括:当第二UCI和第三UCI中包含HARQ-ACK时,判断所述第二PUCCH资源与所述第三PUCCH资源的重叠部分是否满足时间条件;若满足所述时间条件,则根据预先定义的复用传输规则,确定用于同时传输第二UCI和第三UCI的第四PUCCH资源。
具体地,如果存在承载HARQ-ACK的PUCCH,需要判断重叠的PUCCH之间是否满足如下时间条件(Timeline),在满足时间条件时,才允许进行复用传输,时间条件是为了让终端在最早的传输的起始时刻之前,决策如何复用,并根据复用决策完成最早的信道上的传输准备。并且终端不期待出现不满足时间条件的调度情况,则如果出现了不满足时间条件的情况,则被认为是错误调度。
Timeline1:重叠信道中的最早一个信道的起始符号与HARQ-ACK信息对应的PDSCH中的任意一个PDSCH的结束符号之间的时间间隔不短于T1时间;即重叠信道中的最早一个信道的起始符号不早于HARQ-ACK信息对应的PDSCH中的任意一个PDSCH的结束符号之后T1时间;
Timeline2:如果HARQ-ACK有对应的PDCCH,重叠信道中的最早一个信道的起始符号与HARQ-ACK对应的PDCCH中的任意一个PDCCH的结束符号之间的时间间隔不短于T2时间;即重叠信道中的最早一个信道的起始符号不早于HARQ-ACK对应的PDCCH中的任意一个PDCCH的结束符号之后T2时间。
步骤22:判断所述第四PUCCH资源与所述第一PUCCH资源在时域上是否重叠。
步骤23:若用于同时传输所述第二UCI和所述第三UCI的第四PUCCH资源与所述第一PUCCH资源重叠,则丢弃第一目标UCI;其中,所述第一目标UCI为第二UCI与所述第三UCI中的一个。
具体地,若用于同时传输所述第二UCI和所述第三UCI的第四PUCCH资源与所述第一PUCCH资源重叠,则丢弃第一目标UCI,并在第一PUCCH资源上传输所述第一UCI,以及在第二目标UCI对应的PUCCH资源上传输第二目标UCI;其中,所述第一目标UCI为第二UCI与所述第三UCI中的一 个,所述第二目标UCI为第二UCI与所述第三UCI中除所述第一目标UCI的另一个。
例如:若用于同时传输所述第二UCI和所述第三UCI的第四PUCCH资源与所述第一PUCCH资源重叠,则丢弃第三UCI(即第一目标UCI),并在第一PUCCH资源上传输所述第一UCI,以及在第二PUCCH资源上上传输第二UCI,也即通过时分复用(time-division multiplexing,TDM)的方式传输所述第一UCI和第二UCI。
该实施例中,当承载第一UCI的第一PUCCH资源与承载第二UCI的第二PUCCH资源在时域上不重叠,所述第一PUCCH资源与承载第三UCI的第三PUCCH资源在时域上不重叠,且所述第二PUCCH资源和所述第三PUCCH资源在时域上重叠时:若用于同时传输所述第二UCI和所述第三UCI的第四PUCCH资源与所述第一PUCCH资源重叠,则丢弃第一目标UCI,从而在第一PUCCH资源上传输第一UCI,以及在第二目标UCI(第二UCI与第三UCI中除所述第一目标UCI的另一个)对应的PUCCH资源上传输所述第二UCI,即TDM传输第一UCI以及第二目标UCI,以避免由于第二PUCCH资源和第三PUCCH资源重叠,导致原本不重叠的PUCCH资源(第一PUCCH资源和第二PUCCH资源、第一PUCCH资源和第三PUCCH资源)所承载的UCI需要在一个PUCCH资源上传输,从而避免影响第一UCI和第二UCI的传输时延和传输性能。
可选地,根据以上至少一个实施例,所述丢弃第一目标UCI的步骤可以具体包括:
在所述第一UCI为调度请求SR信息的情况下,若存在正(positive)SR信息传输,则丢弃第一目标UCI。
进一步地,根据以上至少一个实施例,所述第一目标UCI为:所述第二UCI和所述第三UCI中低优先级的UCI。

进一步地,根据以上至少一个实施例,在所述第二UCI和所述第三UCI中的一个为信道状态信息CSI的情况下,所述第一目标UCI为:所述第二UCI和所述第三UCI中为CSI的一个。
进一步地,根据以上至少一个实施例,在所述第二UCI和所述第三UCI均为CSI,且所述第二UCI与所述第三UCI的优先级相同的情况下,所述第一目标UCI为:所述第二UCI和所述第三UCI中预定的一个或者任意一个。

进一步地,根据以上至少一个实施例,所述第一目标UCI为:所述第三UCI。
可选地,所述第一UCI为SR信息、CSI和HARQ-ACK信息中的至少一种;所述第二UCI为SR信息、CSI和HARQ-ACK信息中的至少一种;所述第三UCI为SR信息、CSI和HARQ-ACK信息中的至少一种。其中,第二UCI和第三UCI的类型可以相同或不同。

场景一:当所述第一UCI为SR或第一HARQ-ACK或第一CSI,所述第二UCI为第二HARQ-ACK,所述第三UCI为第二CSI时:
若用于同时传输所述第二HARQ-ACK和所述第二CSI的PUCCH资源与用于承载所述SR或所述第一HARQ-ACK或第一CSI的PUCCH资源重叠,则丢弃所述第二CSI;其中,第一UCI和第二HARQ-ACK信息可以对应相同或者不同的优先级。
例如:第一UCI为SR时,SR对应优先级等级1或URLLC业务或高优先级业务类型,HARQ-ACK信息对应优先级等级2或eMBB业务或低优先级业务类型;或者SR信息和HARQ-ACK信息都对应优先级等级1或URLLC业务或高优先级业务类型;或者SR信息和HARQ-ACK信息都对应优先级等级2或eMBB业务或低优先级业务类型;或者HARQ-ACK信息对应优先级等级1或URLLC业务或高优先级业务类型,SR信息对应优先级等级2或eMBB业务或低优先级业务类型。其中,优先级等级1高于优先级等级2。

本公开实施例还提供一种计算机可读存储介质,计算机可读存储介质上存储有计算机程序,该计算机程序被处理器执行时实现上述终端侧的UCI的处理方法实施例的各个过程,且能达到相同的技术效果,为避免重复,这里 不再赘述。其中,所述的计算机可读存储介质,如只读存储器(Read-Only Memory,ROM)、随机存取存储器(Random Access Memory,RAM)、磁碟或者光盘等。
以下结合具体示例,针对上述终端侧和基站侧的UCI的处理方法进行具体说明:
一个承载HARQ-ACK信息(第二UCI)的PUCCH资源和一个承载CSI(第三UCI)的PUCCH资源在时域上重叠,还存在一个承载SR信息(第一UCI)的PUCCH资源和承载该HARQ-ACK信息的PUCCH资源在时域上不重叠,且承载该SR信息的PUCCH资源和承载该CSI的PUCCH资源在时域上也不重叠,如图9所示。图9中的SR表示承载SR信息的PUCCH资源;HARQ-ACK表示承载HARQ-ACK信息的PUCCH资源;CSI表示承载CSI的PUCCH资源。
由于承载该CSI的PUCCH资源和承载该CSI的PUCCH资源在时域上存在重叠,则根据上述实施例中预先定义的复用传输规则(该实施例中可以是配置支持HARQ-ACK信息与CSI同时传输的,否则出现这种重叠的情况,则直接丢弃CSI,从而避免了HARQ-ACK信息与CSI的重叠),确定一个用于同时传输HARQ-ACK信息和CSI的PUCCH资源。
即针对终端侧有以下情况:
情况1:当HARQ-ACK信息有对应的PDCCH时(具体的同上述终端侧实施例的部分,此处不再赘述),此时终端被配置了多个PUCCH资源集合,则根据HARQ-ACK信息和CSI的总比特数确定一个PUCCH资源集合,并根据HARQ-ACK信息对应的PDCCH(具体的为PDCCH所使用的DCI中的PUCCH资源指示域),在确定的PUCCH资源集合中确定一个PUCCH资源,该PUCCH资源为用于同时传输HARQ-ACK信息和CSI的PUCCH资源;
如果该用于同时传输HARQ-ACK信息和CSI的PUCCH资源与该SR信息对应的PUCCH资源在时域上重叠,则直接丢弃CSI,从而避免由于CSI与HARQ-ACK信息的重叠,导致原本不重叠的HARQ-ACK信息和SR信息需要复用传输(即在同一个资源上传输),即此时终端在HARQ-ACK信息对应的PUCCH资源上传输该HARQ-ACK信息,在SR信息对应的PUCCH资 源上传输该SR信息,即采用TDM的方式分别传输HARQ-ACK信息和SR信息,如图10所示。其中,图10中的SR表示承载SR信息的PUCCH资源;HARQ-ACK表示承载HARQ-ACK信息的PUCCH资源;CSI表示承载CSI的PUCCH资源;HARQ-ACK+CSI表示用于同时传输HARQ-ACK信息和CSI的PUCCH资源。
如果该用于同时传输HARQ-ACK信息和CSI的PUCCH资源与该SR信息对应的PUCCH资源在时域上不重叠,则可以在该用于同时传输HARQ-ACK信息和CSI的PUCCH资源上同时传输HARQ-ACK信息和CSI,而SR信息则在SR信息对应的PUCCH资源上传输,如图11所示。其中,图11中的SR表示承载SR信息的PUCCH资源;HARQ-ACK表示承载HARQ-ACK信息的PUCCH资源;CSI表示承载CSI的PUCCH资源;HARQ-ACK+CSI表示用于同时传输HARQ-ACK信息和CSI的PUCCH资源。
情况2:当HARQ-ACK信息没有对应的PDCCH时(具体的同上述终端侧实施例的部分,此处不再赘述),即HARQ-ACK信息为SPS PDSCH的反馈信息,则将HARQ-ACK信息转移到CSI对应的PUCCH资源上实现与CSI的同时传输,即此时CSI对应的PUCCH资源为用于同时传输HARQ-ACK和CSI的PUCCH资源;则由于CSI对应的PUCCH资源原本与SR信息对应的PUCCH资源之间并不重叠,可以实现分别传输,即在CSI对应的PUCCH资源上同时传输HARQ-ACK信息和CSI,在SR信息对应的PUCCH资源上传输SR信息,如图12所示。其中,图12中的SR表示承载SR信息的PUCCH资源;HARQ-ACK表示承载HARQ-ACK信息的PUCCH资源;CSI表示承载CSI的PUCCH资源;HARQ-ACK+CSI表示用于同时传输HARQ-ACK信息和CSI的PUCCH资源。
针对基站侧,按照上述方式确定终端是否传输CSI,从而确定如何接收;即:
当HARQ-ACK信息有对应的PDCCH时,在该用于同时传输HARQ-ACK信息和CSI的PUCCH资源与该SR信息对应的PUCCH资源在时域上重叠时,则确定CSI被丢弃,进而在HARQ-ACK信息对应的PUCCH资源上接收该HARQ-ACK信息,在SR信息对应的PUCCH资源上接收该SR信息;在该 用于同时传输HARQ-ACK信息和CSI的PUCCH资源与该SR信息对应的PUCCH资源在时域上不重叠,则确定在该用于同时传输HARQ-ACK信息和CSI的PUCCH资源上接收HARQ-ACK信息和CSI,在SR信息对应的PUCCH资源上接收SR信息。
当HARQ-ACK信息没有对应的PDCCH时,在CSI对应的PUCCH资源上接收HARQ-ACK信息和CSI,在SR信息对应的PUCCH资源上接收SR信息。
上述情况中,在确定用于同时传输HARQ-ACK信息和CSI的PUCCH资源之前,可以先判断是否满足时间条件,在满足时间条件时,才进行上述操作,如果不满足时间条件,则认为是调度错误,或者直接丢弃CSI;当然,也可以约定不进行时间条件判断,则默认总是可以进行复用传输,从而直接执行上述步骤,本公开不做具体限定。
上述情况中,SR信息可以对应URLLC业务,HARQ-ACK信息可以对应URLLC业务或eMBB业务,CSI可以对应eMBB业务或者CSI不区分对应的业务类型,CSI的优先级为最低;当然,将URLLC业务和eMBB业务替换为其他两种不同的业务类型时,也适用于上述方法;
上述情况中,可以对任何SR信息的状态,如正(positive)SR和负(negative)SR都适用,即不区分SR信息的状态,只要是SR信息对应的PUCCH资源存在上述情况,即可适用;也可以仅对positive SR信息适用,即仅当SR信息为positive SR信息的时候才按照上述方式处理,如果SR信息为negative,则不认为会与情况1中同时传输HARQ-ACK和CSI的PUCCH资源存在冲突,直接在同时传输HARQ-ACK和CSI的资源上传输HARQ-ACK和CSI即可;
上述情况中,SR信息与HARQ-ACK信息和CSI的相对位置仅为示例,其中,CSI对应的PUCCH资源的起始位置超前或落后或对齐HARQ-ACK信息对应的PUCCH资源的起始位置,CSI对应的PUCCH资源的截止位置可以超前或落后或对齐HARQ-ACK信息对应的PUCCH资源的截止位置,SR信息对应的PUCCH资源可以在HARQ-ACK信息和CSI对应的PUCCH资源之前,也可以在HARQ-ACK信息和CSI对应的PUCCH资源之后,本公开不以此为限。
