Description
相关申请的交叉引用
本公开主张在2022年4月15日在中国提交的中国专利申请号No.202210397684.8的优先权,其全部内容通过引用包含于此。
本公开涉及通信技术领域,尤其涉及一种物理上行共享信道(Physical Uplink Shared Channel,PUSCH)发送方法、解析方法、终端和网络设备。
目前通信***中物理上行共享信道(Physical Uplink Shared Channel,PUSCH)支持两种波形,不同波形的主要区别在于是否开启变换预编码(transform precoder)。如果开启变换预编码,PUSCH传输采用离散傅里叶变换扩频的正交频分复用多址(Discrete Fourier Transform-spreading-Orthogonal Frequency Division Multiplexing,DFT-s-OFDM)波形,该波形具有单载波特性,峰值平均功率比(Peak to Average Power Ratio,PAPR)较低,适用于小区边缘覆盖受限场景。如果不开启变换预编码,PUSCH传输采用循环前缀正交频分复用(Cyclic Prefix-Orthogonal Frequency Division Multiplexing,CP-OFDM),该波形对空口无线条件要求比较苛刻,主要用于覆盖不受限的场景下。目前PUSCH是否开启变换预编码主要是通过无线资源控制(Radio Resource Control,RRC)高层参数进行预先配置,具体是PUSCH传输采用的波形在较长的一段时间内都保持不变,只有在RRC参数重配之后才有可能更新变化。可见,目前PUSCH的波形无法动态切换来匹配不同的覆盖需求,导致PUSCH的传输性能比较差。

需要说明的是,图1仅是以目标网络节点和源网络节点属于同一网络设备进行举例说明。
本公开实施例中,网络侧与终端之间可以各自使用一或多根天线进行多输入多输出(Multi Input Multi Output,MIMO)传输,MIMO传输可以是单用户MIMO(Single User MIMO,SU-MIMO)或多用户MIMO(Multiple User MIMO,MU-MIMO)。根据根天线组合的形态和数量,MIMO传输可以是二维MIMO(Two Dimension MIMO,2D-MIMO)、三维MIMO(Three Dimension,3D-MIMO)、全维度MIMO(Full Dimension MIMO,FD-MIMO)或大规模MIMO(massive-MIMO),也可以是分集传输或预编码传输或波束赋形传输等。
请参见图2,图2是本公开实施例提供的一种PUSCH发送方法的流程图,如图2所示,包括以下步骤:
步骤201、终端根据第一PUSCH的参考信道,确定所述第一PUSCH是否开启变换预编码;
步骤202、所述终端发送开启或者关闭变换预编码的第一PUSCH。
本公开实施例中,如果确定第一PUSCH开启变换预编码,PUSCH传输可以采用DFT-s-OFDM波形,如果确定第一PUSCH不开启变换预编码,PUSCH传输可以采用CP-OFDM波形。
需要说明的是,本公开实施例中,并不限定于DFT-s-OFDM波形和CP-OFDM波形,例如:在一些实施方式或者场景中,还可以定义其他多种波形,这些其他多种波形分别与开启变换预编码和不开启变换预编码对应。
上述根据第一PUSCH的参考信道可以是,与上述第一PUSCH关联的信
道,例如:第一PUSCH关联的PDCCH,或者第一PUSCH关联的第二PUSCH。
本公开实施例中,通过上述步骤可以实现参考信道确定第一PUSCH是否开启变换预编码,以实现PUSCH的波形根据参考信道动态切换,以提高PUSCH的传输性能。
作为一种可选的实施方式,所述第一PUSCH包括如下至少一项:
CG-PUSCH;
第一fallback DCI调度的PUSCH;
所述第一fallback DCI激活的PUSCH。
上述CG-PUSCH也可以称作免调度PUSCH。
其中,上述CG-PUSCH可以包括如下至少一项:
Type1 CG-PUSCH初传;
Type2 CG-PUSCH初传。
其中,上述Type1和Type2为协议中定义的两种CG-PUSCH类型,例如:在一些实施方式中,Type1 CG-PUSCH的传输参数通过RRC配置,Type2 CG-PUSCH的一部分传输参数通过RRC配置,另一部分传输参数通过激活下行控制信息(Downlink Control Information,DCI)指示,激活DCI可以是fallback DCI,也可以是non-fallback DCI。
其中,上述第一fallback DCI调度的PUSCH可以包括如下至少一项:
所述第一fallback DCI调度的Type1 CG-PUSCH重传;
所述第一fallback DCI调度的Type2 CG-PUSCH重传;
所述第一fallback DCI调度的DG-PUSCH。
其中,上述第一fallback DCI激活的PUSCH可以包括:
所述第一Fallback DCI激活的Type2 CG-PUSCH初传。
该实施方式中,可以实现动态切换没有动态调度DCI的CG-PUSCH的波形;也可以实现动态切换第一fallback DCI调度的PUSCH的波形;也可以实现动态切换第一fallback DCI激活的PUSCH的波形。例如:对于没有调度DCI的PUSCH以及fallback DCI调度/激活的PUSCH不通过变换预编码开启或者关闭指示域动态切换PUSCH的传输波形的情况下,可以实现为这些PUSCH确定参考信道,根据参考信道实现动态切换传输波形,从而保证这些
PUSCH传输的覆盖要求。
可选的,上述第一fallback DCI不存在第一指示信息,所述第一指示信息用于指示开启或者关闭变换预编码。
上述第一指示信息可以是波形指示信息。
一些实现方式中,上述第一Fallback DCI可以包括:DCI 0_0。
该实施方式中,可以实现在第一fallback DCI不可指示开启或者关闭变换预编码的情况下,动态切换第一fallback DCI调度和/或激活的PUSCH传输采用的波形。
作为一种可选的实施方式,所述参考信道包括:
所述终端接收的承载non-fallback DCI的第一PDCCH。
上述承载non-fallback DCI的第一PDCCH为终端在第一PUSCH之前接收到承载non-fallback DCI的PDCCH,例如:在第一PUSCH之前接收到的,承载non-fallback DCI的最近PDCCH(latest PDCCH),或者也可以理解为承载最后一个non-fallback DCI(last non-fallback DCI)的PDCCH。
该实施方式中,可以实现根据第一PDCCH动态切换第一PUSCH的波形,且不需要引入额外的信令,以节约开销。
可选的,所述第一PDCCH,包括:
所述终端在所述第一PUSCH的起始时域位置之前最近接收到的承载non-fallback DCI的PDCCH。
上述起始时域位置可以是起始符号,例如:上述第一PDCCH可以是,在第一PUSCH的起始符号之前接收到的最近PDCCH。
其中,上述non-fallback DCI可以包括:
调度上行传输的non-fallback DCI;或者
调度下行传输的non-fallback DCI。
上述调度上行传输的non-fallback DCI可以是DCI 0_1/DCI 0_2,上述调度下行传输的non-fallback DCI可以是DCI 1_1/DCI 1_2。
该实施方式中,由于第一PDCCH是在第一PUSCH的起始时域位置之前最近接收到的承载non-fallback DCI的PDCCH,这样可以使得第一PUSCH的波形按照最新的PDCCH确定,以提高动态切换效果。
需要说明的是,本公开实施例中并不限定第一PDCCH为终端在所述第一PUSCH的起始时域位置之前最近接收到的承载non-fallback DCI的PDCCH,例如:在一些实施方式中,上述第一PDCCH可以是终端在特定资源上接收到的承载non-fallback DCI的PDCCH,该特定资源可以是与上述起始时域位置存在协议预定义关系的资源。
可选的,所述终端在所述第一PUSCH的起始时域位置之前最近接收到的承载non-fallback DCI的PDCCH,包括:
所述终端在所述第一PUSCH的起始时域位置之前,在最近的MO接收到的承载non-fallback DCI的PDCCH,且所述PDCCH的结束时域位置与所述第一PUSCH的起始时域位置的时间间隔大于或者等于第一时间间隔。
在一种实现方式中,上述PDCCH可以是在第一PUSCH的起始符号之前第一时间间隔的最近一个MO内接收到的PDCCH。
其中,上述第一时间间隔包括:
所述第一PUSCH的处理时间;或者
预定义的固定时间值。
上述第一PUSCH的处理时间可以是,根据协议计算的第一PUSCH的处理时间,上述预定义的固定时间值可以是协议定义或者网络侧配置的固定值。
该实施方式中,由于PDCCH的结束时域位置与第一PUSCH的起始时域位置的时间间隔大于或者等于第一时间间隔,这样保证终端有充分的时间处理PUSCH。
在一个实施例中,终端准备向网络设备传输Type1 CG-PUSCH初传,由于Type1 CG-PUSCH没有对应的调度和激活DCI,网络设备无法直接动态指示该Type1 CG-PUSCH传输采用的波形,因此,终端可以为该Type1 CG-PUSCH确定参考信道。例如,本实施例中,参考信道为承载non-fallback DCI的PDCCH,终端根据在通过满足CG-PUSCH起始符号之前T的最近一个MO内收到的non-fallback DCI携带的波形指示域确定上述CG-PUSCH的波形。T为CG-PUSCH的处理时间,包括在完整接收最近DCI(latest DCI)后解析该DCI的时间以及按照DCI指示的波形准备CG-PUSCH的时间。T可以通过协议规定的T_(proc,2)确定,或者协议新定义的处理时间,或者直接
通过协议预定义的固定值确定。上述latest DCI的最后一个符号到CG-PUSCH的起始符号之间的间隔要大于T。例如:如图3所示,DCI 0_1为满足时间T的latest DCI。CG-PUSCH的波形由DCI 0_1中的波形指示域确定。
同理,本实施例中的Type1 CG-PUSCH初传也可以是任意DCI激活的Type2 CG-PUSCH初传或者fallback DCI 0_0激活的Type2 CG-PUSCH初传,fallback DCI 0_0调度的Type1 CG-PUSCH重传和Type2 CG-PUSCH重传,或者,fallback DCI 0_0调度的DG-PUSCH。
在另一个实施例中,具体上述实施例1所述,latest non-fallback DCI也可以是调度下行传输的DCI,例如:如图4所示,latest DCI为DCI 1_1。
可选的,所述non-fallback DCI包括在第一CC上的non-fallback DCI,所述第一CC为所述第一PUSCH所在的CC,或者所述第一CC为CC集合中的一个;其中,所述CC集合为所述终端对应的所有CC的集合或者所述终端对应的激活CC(active CC)的集合。
该实施方式中,可以实现根据所述第一PUSCH所在的CC上的第一PDCCH确定第一PUSCH是否开启变换预编码,也可以实现根据CC集合中任一CC上的第一PDCCH确定第一PUSCH是否开启变换预编码,这样可以达到灵活确定第一PUSCH波形的效果。
可选的,在所述第一CC为所述CC集合中的一个,且所述CC集合中有多个CC上存在候选PDCCH的情况下:所述第一CC为所述多个CC中CC索引为预设索引的CC;或者
在所述第一CC为所述CC集合中的一个,且所述CC集合中有多个CC上存在候选PDCCH,且所述多个CC包括所述第一PUSCH所在的CC的情况下:所述第一CC为所述多个CC中所述第一PUSCH所在的CC;或者
在所述第一CC为所述CC集合中的一个,且所述CC集合中有多个CC上存在候选PDCCH,且所述多个CC不包括所述第一PUSCH所在的CC的情况下:所述第一CC为:所述多个CC中CC索引为预设索引的CC或者,所述多个CC中离所述所述第一PUSCH所在的CC最近的CC;
所述候选PDCCH为在所述第一PUSCH的起始时域位置之前最近的MO接收到的承载non-fallback DCI的PDCCH,且所述PDCCH的结束时域位置
与所述第一PUSCH的起始时域位置的时间间隔大于或者等于第一时间间隔。
其中,上述预设索引的CC可以是CC索引最小的,或者CC索引最大的CC。例如:在上述non-fallback DCI为终端上述CC集合中的任意CC上的DCI时,如果多个CC上各自满足第一时间间隔的最近一个PDCCH在时域上存在重叠,可以如下处理方式:则上述non-fallback DCI为上述多个CC中CC索引最小的,或者CC索引最大的CC上的DCI;或者,优先选择上述第一PUSCH所在CC上的DCI;若上述多个CC不包括上述第一PUSCH所在的CC,上述non-fallback DCI为上述多个CC中CC索引最小的,或者CC索引最大的,或者离上述第一PUSCH所在CC最近的CC上的DCI。所述最近的CC是可以是通过计算CC索引值差的绝对值确定的,如果在上述第一PUSCH所在CC的前后各有一个最近的CC,可以选择CC索引更小的CC,或者选择CC索引更大的CC。
在一个实施例中,上述non-fallback DCI还可以是其他激活CC(active CC)上的non-fallback DCI。例如:如图5所示,CG-PUSCH在CC1上传输,CC1上调度PUSCH1的DCI 0_1和CC2上调度PUSCH3的DCI 0_2在时域上重叠。在本实施例中,优先选择CG-PUSCH所在的CC,根据调度PUSCH1的DCI 0_1确定CG-PUSCH的波形。
同理可以根据所有CC中CC索引最小的规则,通过调度PUSCH1的DCI 0_1确定CG-PUSCH的波形。或者,根据所有CC中CC索引最大的规则,通过调度PUSCH3的DCI 0_2确定CG-PUSCH的波形。
作为一种可选的实施方式,所述参考信道包括:
所述终端发送的第二PUSCH。
在一些实现方式中,上述第二PUSCH为所述终端在所述第一PUSCH之前发送的最近一个PUSCH(latest PUSCH)。
在另一些实现方式中,上述第二PUSCH也可以是在特定资源上发送的PUSCH,对此本公开实施例不作限定,该特定资源可以是与上述起始时域位置存在协议预定义关系的资源。
该实施方式中,可以实现根据第二PUSCH动态切换第一PUSCH的波形,不需要引入额外的波形实现动态切换,以节约开销。
可选的,上述终端在所述第一PUSCH之前发送的最近一个PUSCH,包括:
所述终端在所述第一PUSCH的起始时域位置之前的最近一个单位时域资源发送的PUSCH,且所述第二PUSCH的结束时域位置与所述第一PUSCH的起始时域位置的时间间隔大于或者等于第二时间间隔。
上述单位时域资源可以是时隙、子时隙或者其他单位时域资源,例如:上述第二PUSCH可以是,在第一PUSCH的起始符号之前第二时间间隔的最近一个时隙内发送的PUSCH。
在一些实现方式中,所述第二PUSCH为所述最近一个单位时域资源内起始时域位置最晚的PUSCH;或者
所述第二PUSCH为所述最近一个单位时域资源内结束时域位置最晚的PUSCH。
例如:上述第二PUSCH可以是为在第一PUSCH的起始时域位置之前最近一个时隙内起始符号最晚的PUSCH,或者结束符号最晚的PUSCH。
上述第二时间间隔可以包括:
所述第一PUSCH的准备时间;或者
预定义的固定时间值。
上述准备时间可以是根据协议计算的第一PUSCH的准备时间,上述准备时间可以是协议定义或者网络侧配置的固定值。
在一个实施例中,终端准备向网络设备传输Type1 CG-PUSCH,由于Type1 CG-PUSCH没有对应的调度/激活DCI,网络设备无法直接动态指示该Type1 CG-PUSCH传输采用的波形。因此,终端可以为该Type1 CG-PUSCH确定参考信道。例如,本实施例中,参考信道为non fallback DCI调度的DG-PUSCH,终端根据在通过满足CG-PUSCH起始符号之前T的最近一个时隙内的起始符号最晚的DG-PUSCH(latest DG-PUSCH)采用的波形确定所述CG-PUSCH的波形。T为CG-PUSCH的准备时间,包括按照latest DG-PUSCH的波形准备CG-PUSCH的时间。T可以通过协议规定的T_(proc,2)确定,或者协议新定义的准备时间,或者直接通过协议预定义的固定值确定。上述最晚的DG-PUSCH的最后一个符号到CG-PUSCH的起始符号之间的间隔要大
于T。例如:如图6所示,DG-PUSCH1为满足时间T的latest DG-PUSCH。CG-PUSCH的波形由DG-PUSCH1的波形确定。
同理,本实施例中的Type1 CG-PUSCH初传也可以是Type 2 CG-PUSCH初传或者fallback DCI 0_0激活的Type2 CG-PUSCH初传,fallback DCI 0_0调度的Type1 CG-PUSCH重传和Type2 CG-PUSCH重传,或者,fallback DCI 0_0调度的DG-PUSCH。
可选的,所述第二PUSCH包括如下至少一项:
所述终端在第二CC上,且所述第一PUSCH之前发送的最近一个PUSCH,所述第二CC为所述第一PUSCH所在的CC,或者,所述第二CC为CC集合中的一个;其中,所述CC集合为所述终端对应的所有CC的集合或者所述终端对应的激活CC的集合。
该实施方式中,可以实现根据所述第一PUSCH所在的CC上的第二PUSCH确定第一PUSCH是否开启变换预编码,也可以实现根据CC集合中任一CC上的第二PUSCH确定第一PUSCH是否开启变换预编码,这样可以达到灵活确定第一PUSCH波形的效果。
可选的,在所述第二CC为所述CC集合中的一个,且所述CC集合中有多个CC上存在候选PUSCH的情况下:所述第二CC为所述多个CC中CC索引为预设索引的CC;或者
在所述第二CC为所述CC集合中的一个,且所述CC集合中有多个CC上存在候选PUSCH,且所述多个CC包括所述第一PUSCH所在的CC的情况下:所述第二CC为所述多个CC中所述第一PUSCH所在的CC;或者
在所述第二CC为所述CC集合中的一个,且所述CC集合中有多个CC上存在候选PUSCH,且所述多个CC不包括所述第一PUSCH所在的CC的情况下:所述第二CC为:所述多个CC中CC索引为预设索引的CC或者,所述多个CC中离所述所述第一PUSCH所在的CC最近的CC;
所述候选PUSCH为在所述第一PUSCH的起始时域位置之前的最近一个单位时域资源发送的起始时域位置最晚或者结束时域位置最晚的PUSCH,且所述PUSCH的结束时域位置与所述第一PUSCH的起始时域位置的时间间隔大于或者等于第二时间间隔。
上述预设索引的CC可以是CC索引最小的,或者CC索引最大的CC。例如:当上述第二PUSCH位于所述终端包含的任意CC时,如果多个CC上各自满足所述第二时间间隔的最近一个时隙内收到的PUSCH的起始符号,或者结束符号在时域上相同,可以存在如下处理方式:
上述第二PUSCH为上述多个CC中CC索引最小的,或者CC索引最大的CC上的PUSCH;
或者,优先选择上述第一PUSCH所在CC上的PUSCH;若上述多个CC不包括上述第一PUSCH所在的CC,上述第二PUSCH为上述多个CC中CC索引最小的,或者CC索引最大的,或者离上述第一PUSCH所在CC最近的CC上的PUSCH。
在一个实施例中,上述第二PUSCH还可以是其他active CC上的满足时间要求T的DG-PUSCH。如图7所示,CG-PUSCH在CC1上传输,终端根据满足时间间隔T的最近一个时隙内结束符号最晚的PUSCH确定参考PUSCH,在本实施例中找到了CC1上的DG-PUSCH1和CC2上的DG-PUSCH2,且两个PUSCH的结束符号位置相同。根据所有CC中CC索引最大的规则,通过CC2上PUSCH2的波形确定CG-PUSCH的波形。
同理,可以根据优先选择CG-PUSCH所在的CC的规则,通过CC1上PUSCH1的波形确定CG-PUSCH的波形。或者,根据所有CC中CC索引最小的规则,通过CC1上PUSCH1的波形确定CG-PUSCH的波形。
作为一种可选的实施方式,所述第二PUSCH包括如下至少一项:
non-fullback DCI调度的PUSCH;
non-fullback DCI激活的PUSCH;
fullback DCI调度的PUSCH;
fullback DCI激活的PUSCH;
CG-PUSCH。
该实施方式中,可以支持根据多种PUSCH动态切换第一PUSCH的波形。
在一个实施例中,参考信道可以是DG-PUSCH,DG-PUSCH可以是由non-fallback DCI调度的,参考信道还可以是任意DCI(包括non-fallback DCI和fallback DCI)调度的PUSCH,或者任意不区分DG/CG的PUSCH。例如:
如图8所示,DG-PUSCH2的波形根据DG-PUSCH1的波形确定,CG-PUSCH的波形根据DG-PUSCH的波形确定。
作为一种可选的实施方式,所述终端根据第一PUSCH的参考信道,确定第一PUSCH是否开启变换预编码,包括:
所述终端根据所述non-fallback DCI的第一指示信息,确定所述第一PUSCH是否开启变换预编码,所述第一指示信息用于指示开启或者关闭变换预编码;或者
所述终端根据所述第二PUSCH的变换预编码开启或者关闭状态,确定所述第一PUSCH是否开启变换预编码。
其中,上述第一指示信息可以是波形指示信息。例如:终端根据上述实施方式中描述的第一PDCCH上承载的non-fallback DCI中的波形指示信息确定第一PUSCH的传输波形。
上述终端根据所述第二PUSCH的变换预编码开启或者关闭状态,确定所述第一PUSCH是否开启变换预编码可以是,终端根据上述第二PUSCH传输采用的波形确定第一PUSCH的传输波形,如第一PUSCH和第二PUSCH采用相同的波形。
作为一种可选的实施方式,所述参考信道的结束时间位置与所述第一PUSCH的起始时域位置之间的间隔小于或者等于第三时间间隔。
上述结束位置可以是结束符号,上述起始时域位置可以是起始符号,例如:上述第一PUSCH的起始符号与上述参考信道的最后一个符号之间的间隔小于上述第三时间间隔。
上述第三时间间隔可以是协议定义或者网络侧配置的时间间隔。
该实施方式中,由于参考信道的结束时间位置与所述第一PUSCH的起始时域位置之间的间隔小于或者等于第三时间间隔,这样实现第一PUSCH的动态波形指示只在一段时间内生效,以避免动态波形指示生效时间太长而导致波形切换性能下降。
在一个实施例中,动态波形指示只在一段时间内生效,如协议预定义生效时间为上述第三时间间隔K。如果Type1 CG-PUSCH的起始符号与最近接收的non fallback DCI(latest non fallback DCI)或者最近发送的PUSCH(latest
PUSCH)的最后一个符号之间的间隔满足不小于T且不大于K,则可以根据latest DCI或者latest PUSCH对应的波形确定Type1 CG-PUSCH的传输波形,其中,上述T为上述第一时间间隔或者第二时间间隔。在一些实施方式中,在不满足上述要求的情况下,CG-PUSCH的传输波形由配置授权配置(configuredGrantConfig)中配置的变换预编码(transformPrecoder)或者消息3变换预编码(msg3-transformPrecoder)配置的波形传输该CG-PUSCH。
同理,本实施例中的Type1 CG-PUSCH初传也可以是Type2 CG-PUSCH初传或者fallback DCI 0_0激活的Type2 CG-PUSCH初传,fallback DCI 0_0调度的Type1 CG-PUSCH重传和Type2 CG-PUSCH重传,或者,fallback DCI 0_0调度的DG-PUSCH。如果是fallback DCI 0_0调度的DG-PUSCH,终端根据PUSCH-Config中配置的transformPrecoder或者msg3-transformPrecoder确定DG-PUSCH的波形。
本公开实施例中,终端根据第一PUSCH的参考信道,确定所述第一PUSCH是否开启变换预编码;所述终端发送开启或者关闭变换预编码的第一PUSCH。这样可以实现参考信道确定第一PUSCH是否开启变换预编码,以实现PUSCH的波形根据参考信道动态切换,以提高PUSCH的传输性能。
