可以理解的是，本申请的实施例中，PUSCH只是作为上行数据信道的一种举例，在不同的系统和不同的场景中，数据信道可能有不同的名称，本申请的实施例对此并不做限定。
终端设备向网络设备发送数据前，先确定名义PUSCH，采用3GPP R15或R16传输机制传输名义PUSCH，名义PUSCH占用的时域资源上承载有数据。
应理解，所述名义(nominal)PUSCH是由网络设备动态调度(dynamic grant)的，是终端设备根据网络设备发送的上行授权调度信息确定的PUSCH，并不一定为终端设备实际传输的PUSCH。这里的上行授权调度信息可以通过下行控制信息(downlink control information，DCI)承载在物理下行控制信道(physical downlink control channel，PDCCH)中。
在一些实施例中，上行授权调度信息可以指示时域资源分配信息列表中的时域资源分配信息，所述时域资源分配信息指示偏移值、名义PUSCH的起始符号的编号和名义PUSCH的长度。例如，上行授权调度信息包括时域资源分配信息的索引，终端设备根据时域资源分配信息的索引查询时域资源分配信息列表，确定时域资源分配信息。终端设备可以根据名义PUSCH的起始符号和名义PUSCH的长度确定名义PUSCH，根据偏移值确定发送名义PUSCH的时隙，即将PDCCH的时隙的编号与偏移值之和的值确定为传输名义PUSCH的时隙的编号，采用3GPP R15或R16传输机制传输名义PUSCH。偏移值为传输PDCCH的时隙的编号到传输名义PUSCH的时隙的编号的差值。
时域资源分配信息列表是可以网络设备通过高层信令为终端设备配置的。时域资源分配信息列表包括至少一个时域资源分配信息。
例如，时域资源分配信息列表可以是时域资源分配(time domain resource allocation，TDRA)表格。TDRA表格包括N行，N为整数，N≥1，且N不大于64。每行表示一个时域资源分配信息。
应理解，每行取值对应一个时隙内的偏移值和起始和长度指示值(start and length indicator value，SLIV)。SLIV为在时隙内终端设备发送名义PDSCH的时域位置(时域资源)，该时域资源可以包括至少一个OFDM符号。SLIV包括名义PUSCH的起始符号的编号和名义PUSCH的长度。
示例的，如图2所示，一个时隙内的SLIV的示例图。一个时隙内包括16个可以发送PUSCH的时域资源。具体地，网络设备可以从TDRA表格中选择一个时域资源位置来承载PUSCH。
可选的，网络设备可以为终端设备配置R15传输机制的TDRA表格和R16传输机 制的TDRA表格。
R15传输机制可以是指在K个连续时隙上重复发送K个名义PUSCH，一个时隙发送一个名义PUSCH，每个时隙内采用相同的时域符号发送名义PUSCH，其中，K为大于或等于1的整数。
可选的，在本文中，所述“连续”可以描述为连续可用的。
可选的，R15传输机制的时隙聚合又可称为PUSCH重复传输类型A。
如图3所示，对R15传输机制举例说明。
当K＝1时，基于时隙单次传输名义PUSCH，即在1个时隙上发送1个名义PUSCH。如图3中的(a)所示，假设名义PUSCH的长度为4个符号，名义PUSCH的起始符号为符号4，则在时隙n中的第4个符号和第7个符号上发送名义PUSCH。
当K大于1时，基于时隙聚合传输名义PUSCH，即在K个连续可用的时隙中的每个时隙上发送1个名义PUSCH。如图3中的(b)所示，假设K＝2，名义PUSCH的长度为4个符号，名义PUSCH的起始符号为符号4，则在时隙n中的第4个符号和第7个符号上第一次发送名义PUSCH，在时隙n+1中的第4个符号和第7个符号上第二次发送名义PUSCH。
对于基于动态调度的名义PUSCH，如果高层信令配置了PUSCH聚合因子(pusch-AggregationFactor)K，则终端设备在K个连续可用的时隙上重复发送同一个传输块，且在所述连续可用的时隙中的每一个时隙都采用相同的符号分配。例如，时域资源分配信息还可以包括重复次数，该重复次数指示时隙聚合的PUSCH聚合因子(pusch-AggregationFactor)K。例如，K的取值可以是2、4、6、8、10或16。
可选的，R15传输机制的时隙聚合传输的重复次数K也可以通过与R16PUSCH传输机制相同的方式动态指示，即在TDRA表格中加一列用于指示重复次数，该重复次数指示时隙的重复次数，重复次K可以通过上行调度信令(DCI格式(format)0_1/DCI格式)指示K。
R16传输机制为在一个时隙的时域资源上传输M个名义PUSCH、或者在连续可用的多个所述时隙的时域资源上传输M个名义PUSCH，所述M个名义PUSCH包括第一名义PUSCH，其中，所述M为大于或等于1的整数。
需要说明的是，M个名义PUSCH的时域资源分配是背靠背的(back-to-back)。例如第m个名义PUSCH的起始符号为第m-1个名义PUSCH的结束符号的下一个符号。
第m个名义PUSCH的起始时隙表示为
Figure PCTCN2019116895-appb-000001
在所述时隙中的起始符号表示为
Figure PCTCN2019116895-appb-000002
第m个名义PUSCH的结束时隙表示为
Figure PCTCN2019116895-appb-000003
在所述时隙中的结束符号表示为
Figure PCTCN2019116895-appb-000004
其中K s为PUSCH传输起始时隙，
Figure PCTCN2019116895-appb-000005
表示一个时隙中的符号数，一般为14。
M是由网络设备动态指示的。
应理解，如果高层信令配置终端设备支持R16传输机制，TDRA表格中存在一列用于指示重复次数，该重复次数指示重复传输名义PUSCH的次数，重复次数M可以 通过上行调度信令(DCI格式0_1/DCI格式)指示。
可选的，R16传输机制又可以称为PUSCH重复类型B。
对于R16传输机制，针对PUSCH映射类型A，名义PUSCH的起始符号S与名义PUSCH的长度之和的取值范围为{4,14}；针对PUSCH映射类型B，名义PUSCH的起始符号S与名义PUSCH的长度之和的取值范围为{1,14}。
对于R16传输机制，名义PUSCH的起始符号S与名义PUSCH的长度之和的取值范围为{1,27}。
如图4所示，对R16传输机制举例说明。
当M＝1时，传输1个名义PUSCH。如图4中的(a)所示，假设名义PUSCH的长度为8个符号，名义PUSCH的起始符号为符号9，在时隙n中的第9个符号至第14个符号和时隙n+1中的第1个符号和第2个符号上发送名义PUSCH。但是，名义PUSCH横跨时隙边界，则被时隙边界切分为两个PUSCH，实际传输第一PUSCH和第二PUSCH，第一PUSCH和第二PUSCH上承载相同的传输块。
如图4中的(b)所示，假设名义PUSCH的长度为16个符号，名义PUSCH的起始符号为符号1，在时隙n中的第1个符号至第14个符号和时隙n+1中的第1个符号和第2个符号上发送名义PUSCH。但是，名义PUSCH横跨时隙边界，则被时隙边界切分为两个PUSCH，实际传输第一PUSCH和第二PUSCH，第一PUSCH和第二PUSCH上承载相同的传输块。
当M大于1时，传输至少2个名义PUSCH。如图4中的(c)所示，假设M＝3，名义PUSCH的长度为4个符号，名义PUSCH的起始符号为时隙n中的符号4，在时隙n中的第4个符号至第7个符号上第一次发送名义PUSCH(第一PUSCH)。在时隙n中的第8个符号至第11个符号上第二次发送名义PUSCH(第二PUSCH)。在时隙n中的第12个符号至第14个符号和时隙n+1中的第1个符号上第三次发送名义PUSCH。但是，第三次发送的名义PUSCH横跨时隙边界，则被时隙边界切分为两个PUSCH，实际传输第三PUSCH和第四PUSCH，第三PUSCH和第四PUSCH上承载相同的传输块，且与其他没有别切分的名义PUSCH上承载的传输块相同。
为了解决网络设备指示去使能动态指示重复次数M后，终端设备采用哪种方式传输PUSCH的问题，本申请实施例提供了一种发送PUSCH的方法。所述方法包括：在终端设备接收到网络设备发送的去使能动态指示重复次数M的信息后，终端设备采用R16传输机制传输一个名义PUSCH；或者，终端设备采用R16传输机制，根据PUSCH聚合因子K传输K个名义PUSCH；或者，终端设备采用R15规定的基于时隙的单次传输或基于时隙的重复(slot-based repetition)。从而，在网络设备指示去使能动态指示重复次数后，终端设备可以根据上述方式传输名义PUSCH。
下面将结合附图对本申请实施例的实施方式进行详细描述。
图5为本申请实施例提供的一种发送物理上行共享信道的方法流程图。这里以网络设备和终端设备为例进行说明。假设第一传输方式为3GPP R15传输机制。第二传输方式为R15传输机制。如图5所示，该方法可以包括：
S501、网络设备向终端设备发送第一信息。
网络设备可以通过高层信令向终端设备发送第一信息。高层信令可以是指高层协 议层发出的信令。高层协议层为物理层以上的至少一个协议层。其中，高层协议层具体可以包括以下协议层中的至少一个：媒体接入控制(medium access control，MAC)层、无线链路控制(radio link control，RLC)层、分组数据会聚协议(packet data convergence protocol，PDCP)层、无线资源控制(radio resource control，RRC)层和非接入层(non access stratum，NAS)。
例如，网络设备可以通过RRC信令向终端设备发送第一信息，第一信息使能第一传输方式。
第一传输方式为在一个时间单元的时域资源上传输M个名义PUSCH、或者在连续可用的多个所述时间单元的时域资源上传输M个名义PUSCH，M个名义PUSCH包括第一名义PUSCH，其中，所述M为大于或等于1的整数。
可选的，第一信息还使能第二传输方式。例如，承载第二信息的RRC信令包含两个状态，一个状态指示使能第一传输方式，另一个状态指示使能第二传输方式。这两种状态是对立的，不能同时出现的。所述第二信息是为每个DCI格式独立配置的。例如，DCI格式0_1的第二信息和DCI格式0_2的第二信息是独立配置的。
在本文中，第一信息使能第一传输方式。
S502、终端设备接收网络设备发送的第一信息。
在一些实施例中，网络设备可以通过RRC信令向终端设备发送第一信息，第一信息使能第一传输方式，即终端设备采用第一传输方式发送名义PUSCH。具体的解释可以参考S501的阐述，不予赘述。
S503、网络设备向终端设备发送第二信息。
在一些实施例中，网络设备可以通过RRC信令向终端设备发送第二信息，第二信息去使能动态指示重复次数。
需要说明的是，第二信息为与第一信息不同的RRC信令中的信元(information element，IE)。或者，第二信息为DCI中的字段。或者，第二信息为序列。序列可以是参考信号，如解调参考信号(demodulation reference signal，DMRS)。
S504、终端设备接收网络设备发送的第二信息。
在一些实施例中，网络设备可以通过RRC信令向终端设备发送第二信息，第二信息去使能动态指示重复次数。具体的解释可以参考S503的阐述，不予赘述。
S505、终端设备根据第一传输方式或第二传输方式向网络设备发送第一名义PUSCH。
在一些实施例中，终端设备发送第一名义PUSCH前，可以先确定第一名义PUSCH和传输第一名义PUSCH的时隙。例如，根据上行授权调度信息和TDRA表格确定偏移值和SLIV。如图6所示，该方法还包括S601～S606。
S601、网络设备向终端设备发送时域资源分配信息列表。
S602、终端设备接收网络设备发送的时域资源分配信息列表。
时域资源分配信息列表可以是指TDRA表格。关于TDRA表格的解释可以参考上述阐述。
S603、网络设备向终端设备发送第一控制信息。
S604、终端设备接收网络设备发送的第一控制信息。
第一控制信息可以是上行授权调度信息。第一控制信息承载于PDCCH中。第一控制信息用于指示发送第一名义PUSCH和第一时域资源分配信息，时域资源分配信息列表包括第一时域资源分配信息，第一时域资源分配信息指示第一偏移值、第一符号的编号和第一长度。第一偏移值为传输PDCCH的时隙的编号到传输第一名义PUSCH的时隙的编号的差值。第一符号为发送第一名义PUSCH的起始时刻。第一长度为第一名义PUSCH的长度。
S605、终端设备根据第一控制信息和时域资源分配信息列表确定第一时域资源分配信息。
在一些实施例中，上行授权调度信息包括第一时域资源分配信息的索引，终端设备根据时域资源分配信息的索引查询时域资源分配信息列表，确定第一时域资源分配信息。
S606、终端设备根据第一偏移值确定发送第一名义PUSCH的第一时间单元。
终端设备可以根据第一符号和第一长度确定第一名义PUSCH，根据第一偏移值确定发送第一名义PUSCH的第一时间单元，即将PDCCH的时间单元的编号与第一偏移值之和的值确定为传输第一名义PUSCH的第一时间单元的编号，采用3GPP R15或R16传输机制传输第一名义PUSCH。第一时间单元可以是时隙。
应理解，在采用3GPP R16传输机制传输第一名义PUSCH时，第一名义PUSCH为传输的第一个名义PUSCH。
S506、网络设备根据第一传输方式或第二传输方式接收终端设备发送的第一名义PUSCH。
网络设备可以在上行授权调度信息指示的时域位置上接收终端设备发送的第一名义PUSCH。上行授权调度信息指示的时域位置可以参考上述终端设备确定第一名义PUSCH的阐述，不予赘述。
接下来，结合附图对根据第一传输方式或第二传输方式传输第一名义PUSCH的可能的实现方式进行详细说明。所述“传输第一名义PUSCH”可以是指发送第一名义PUSCH或接收第一名义PUSCH。
在第一种可能的实现方式中，当M＝1时，终端设备根据第一传输方式发送1次第一名义PUSCH，即采用R16传输机制发送1次第一名义PUSCH。
具体的，根据第一符号和第一长度在第一时间单元内发送第一PUSCH集合。可理解的，从第一时间单元内的第一符号开始，根据第一长度在第一时间单元的时域资源上发送第一PUSCH集合。第一名义PUSCH的起始时刻为第一符号。第一时间单元的结束时刻在第一名义PUSCH的起始时刻与第一名义PUSCH的结束时刻之间。第一PUSCH集合包括第一PUSCH和第三PUSCH，其中第一PUSCH对应的时域资源为第一时间单元内从第一名义PUSCH的起始时刻之后的连续有效的上行符号，第三PUSCH对应的时域资源为第一时间单元内、在第一名义PUSCH的起始时刻之后的至少一个非上行符号之后的连续有效上行符号。
在一些实施例中，第一时间单元的结束时刻在第一名义PUSCH的结束时刻之后。第一PUSCH集合对应的时域资源为在第一时间单元内第一名义PUSCH对应的全部时域资源。
示例的，如图7所示。假设第一名义PUSCH的长度L为8个符号，第一名义PUSCH的起始符号为符号3，在时隙n中的第3个符号至第10个符号上发送第一名义PUSCH。
在另一些实施例中，第一时间单元的结束时刻在第一名义PUSCH的结束时刻之前。第一PUSCH集合对应的时域资源为在第一时间单元内第一名义PUSCH对应的部分时域资源。终端设备还可以发送第二PUSCH集合，第二PUSCH集合对应的时域资源是根据第一符号和第一长度确定的在第一时间单元的结束时刻之后的时域资源。
示例的，如图8所示。假设第一名义PUSCH的长度L为8个符号，第一名义PUSCH的起始符号为符号11，在时隙n中的第11个符号至第14个符号和时隙n+1中的第1个符号至第4个符号上映射第一名义PUSCH。由于第一名义PUSCH横跨时隙边界，时隙边界将第一名义PUSCH切分为两个PUSCH，即第一PUSCH和第二PUSCH。第一PUSCH集合包括第一PUSCH。第二PUSCH集合包括第二PUSCH。终端设备在时隙n中的第11个符号至第14个符号上发送第一PUSCH，以及在时隙n+1中的第1个符号至第4个符号上发送第二PUSCH。第一PUSCH和第二PUSCH上承载相同的传输块。网络设备在第一PUSCH集合对应的资源上接收第一PUSCH集合，以及在第二PUSCH集合对应的资源上接收第二PUSCH集合。
需要说明的是，终端设备从第一名义PUSCH的起始时刻开始根据第一名义PUSCH的长度在时域的有效上行符号上映射(或称为虚拟映射)第一名义PUSCH。
所谓有效上行符号是指用于映射PUSCH或上行信息的符号。有效上行符号还可以包括被时隙格式指示器(slot format indicator，SFI)指示为上行的灵活符号。所述上行信息包括上行控制信息和上行数据信息。或者，所述上行信息包括上行控制信息。或者，所述上行信息包括上行数据信息。
所述非上行符号包括下行符号、被SFI指示为下行的灵活符号和短时间间隔内的符号。所述下行符号用于映射PDSCH或下行信息的符号。所述下行信息包括下行控制信息和下行数据信息。或者，所述下行信息包括下行控制信息。或者，所述下行信息包括下行数据信息。
所述短时间间隔可以是指第一时间间隔。短时间间隔小于或不大于第一时间间隔。第一时间间隔的长度可以是指单个符号(Orphan symbol)的长度。
第一控制信息指示的第一名义PUSCH的起始时刻至第一时间单元的结束时刻之间包括至少一个有效上行符号和至少一个非上行符号。
第一名义PUSCH的起始时刻可以在第一时间单元内。第一名义PUSCH映射到至少一个有效上行符号上，且第一名义PUSCH在映射时跳过至少一个非上行符号。
可理解的，用于映射第一名义PUSCH的时域资源包括至少两个上行区域。所述至少两个上行区域各包括至少一个有效上行符号。所述至少两个上行区域中的任意一个上行区域由时间连续的P个有效上行符号组成。至少一个上行区域的时域长度之和对应于第一控制信息指示的第一名义PUSCH的长度，P为正整数。
所述至少两个上行区域中任意两个相邻的上行区域之间包括非上行符号，即不包括有效上行符号。
在另一些实施例中，第一时间单元的结束时刻在第一名义PUSCH的结束时刻之前。第一PUSCH集合对应的时域资源为在第一时间单元内第一名义PUSCH对应的部 分时域资源。示例的，如图9所示。假设第一名义PUSCH的长度L为8个符号，第一名义PUSCH的起始符号为符号5。在时隙n中的第5个符号至第8个符号、时隙n中的第13个符号和第14个符号和时隙n+1中的第1个符号和第2个符号上映射第一名义PUSCH。其中，由于时隙n中的第9个符号至第12个符号是下行符号，所以跳过第9个符号至第12个符号，推迟映射第一名义PUSCH，在下行符号后的第一个上行符号(时隙n的第12个符号)开始继续映射第一个名义PUSCH，即在时隙n中的第13个符号和第14个符号继续映射第一名义PUSCH。
另外，第一名义PUSCH横跨时隙边界，时隙边界将第一名义PUSCH切分为两个PUSCH，映射在时隙n的第13个符号至第14个符号上的PUSCH可以称为第二PUSCH，映射在时隙n+1的第1个符号和第1个符号上的PUSCH可以称为第三PUSCH。第一PUSCH集合包括第一PUSCH和第二PUSCH。第二PUSCH集合包括第三PUSCH。第一PUSCH和第二PUSCH位于同一个上行区域。
终端设备在时隙n中的第5个符号至第8个符号上发送第一PUSCH、在时隙n中的第13个符号至第14个符号上发送第二PUSCH和在时隙n+1中的第1个符号至第2个符号上发送第三PUSCH。第一PUSCH、第二PUSCH和第三PUSCH上承载相同的传输块。网络设备在第一PUSCH集合对应的资源上接收第一PUSCH集合，以及在第二PUSCH集合对应的资源上接收第二PUSCH集合。
在第二种可能的实现方式中，终端设备根据第二传输方式发送第一名义PUSCH，即采用R15规定的基于时隙的单次传输发送第一名义PUSCH。根据第一符号和第一长度在第一时间单元内对第一名义PUSCH进行单次传输。
可理解的，从第一时间单元内的第一符号开始，根据第一长度在第一时间单元的时域资源上发送第一名义PUSCH。第一名义PUSCH的起始时刻为第一符号，第一时间单元的结束时刻在第一名义PUSCH的起始时刻与第一名义PUSCH的结束时刻之间。
在一些实施例中，第一时间单元的结束时刻在第一名义PUSCH的结束时刻之后。第一名义PUSCH对应的时域资源为在第一时间单元内第一名义PUSCH对应的全部时域资源。
示例的，如图10所示。假设第一名义PUSCH的长度L为8个符号，第一名义PUSCH的起始符号为符号3，在时隙n中的第3个符号至第10个符号上发送第一名义PUSCH。
在另一些实施例中，第一时间单元的结束时刻在第一名义PUSCH的结束时刻之前。第一名义PUSCH对应的时域资源为在第一时间单元内第一名义PUSCH对应的部分时域资源。在第一时间单元的结束时刻之后不发送第一名义PUSCH。
示例的，如图11所示。假设第一名义PUSCH的长度L为18个符号，第一名义PUSCH的起始符号为符号1，在时隙n中的第1个符号至第14个符号上映射第一名义PUSCH。由于第一名义PUSCH横跨时隙边界，时隙边界将第一名义PUSCH切分为两个PUSCH，即第一PUSCH和第二PUSCH。终端设备在时隙n中的第1个符号至第14个符号上发送第一PUSCH，不发送第二PUSCH。网络设备在第一PUSCH对应的资源上接收第一PUSCH。
示例的，如图12所示。假设第一名义PUSCH的长度L为18个符号，第一名义PUSCH的起始符号为符号1。由于时隙n中的第12个符号是下行符号，因此，在时 隙n中的第1个符号至第11个符号上映射第一名义PUSCH。终端设备在时隙n中的第1个符号至第11个符号上发送第一PUSCH。网络设备在第一PUSCH对应的资源上接收第一PUSCH。
在第三种可能的实现方式中，终端设备根据第二传输方式的基于时隙的重复发送第一名义PUSCH，即采用R15规定的基于时隙的重复发送第一名义PUSCH。根据第一符号和第一长度在M个时间单元的每个时间单元内发送第一名义PUSCH。
在一些实施例中，终端设备接收到网络设备发送的第三信息，第三信息指示时隙聚合因子K的取值。若K不等于M，由于M的网络设备动态指示的，是网络设备根据上行信道质量实时确定的，因此终端设备可以根据第二传输方式发送M个第一名义PUSCH，从而，提高数据传输的可靠性和自适应性。
可理解的，从M个时间单元的每个时间单元内的第一符号开始，根据第一长度发送第一名义PUSCH。第一名义PUSCH的起始时刻为第一符号。时间单元的结束时刻在第一名义PUSCH的起始时刻与第一名义PUSCH的结束时刻之间，M个时间单元包括第一时间单元。
在一些实施例中，时间单元的结束时刻在第一名义PUSCH的结束时刻之后。第一名义PUSCH对应的时域资源为在第一时间单元内第一名义PUSCH对应的全部时域资源。
示例的，如图13所示。假设M＝2，第一名义PUSCH的长度L为8个符号，第一名义PUSCH的起始符号为符号7，在时隙n中的第7个符号至第14个符号上第一次发送第一名义PUSCH，在时隙n+1中的第7个符号至第14个符号上第二次发送第一名义PUSCH。
在另一些实施例中，时间单元的结束时刻在第一名义PUSCH的结束时刻之前。第一名义PUSCH对应的时域资源为在第一时间单元内第一名义PUSCH对应的部分时域资源。在M个时间单元的结束时刻之后不发送第一名义PUSCH。
示例的，如图14所示。假设M＝2，第一名义PUSCH的长度L为8个符号，第一名义PUSCH的起始符号为符号11。在时隙n中的第11个符号至第14个符号上映射第一名义PUSCH。由于第一名义PUSCH横跨时隙边界，时隙边界将第一名义PUSCH切分为两个PUSCH，即第一PUSCH和第二PUSCH。终端设备在时隙n中的第11个符号至第14个符号上发送第一PUSCH，不发送第二PUSCH。网络设备在时隙n中的第一PUSCH对应的资源上接收第一PUSCH。
同理，在时隙n+1中的第11个符号至第14个符号上映射第一名义PUSCH。由于第一名义PUSCH横跨时隙边界，时隙边界将第一名义PUSCH切分为两个PUSCH，即第一PUSCH和第二PUSCH。终端设备在时隙n+1中的第11个符号至第14个符号上发送第一PUSCH，不发送第二PUSCH。网络设备在时隙n+1中的第一PUSCH对应的资源上接收第一PUSCH。
在另一些实施例中，终端设备接收到网络设备发送的第三信息，第三信息指示时隙聚合因子K的取值。若K等于M，终端设备可以根据第二传输方式发送M个第一名义PUSCH，相当于终端设备可以根据第二传输方式发送K个第一名义PUSCH，与采用R15规定的基于时隙的重复(slot-based repetition)发送第一名义PUSCH的机制 相同。
在第四种可能的实现方式中，终端设备接收到网络设备发送的第三信息，第三信息指示时隙聚合因子K的取值。终端设备根据第一传输方式发送K个第一名义PUSCH，即采用R16传输机制发送K个第一名义PUSCH。
可理解的，从第一时间单元内的第一符号开始，根据第一长度发送K个名义PUSCH，K个名义PUSCH包括第一名义PUSCH。
在本文中，所述名义PUSCH为重复传输第一控制信息指示的第一名义PUSCH中的第i个名义PUSCH，i为整数，1≤i≤K。
当i＝1时，K个名义PUSCH中的第一个名义PUSCH的起始时刻对应时域资源分配字段中的名义PUSCH的起始时刻，即第一符号的起始时刻(第一名义PUSCH的起始时刻)。K个名义PUSCH中的第一个名义PUSCH的长度对应时域资源分配字段中的名义PUSCH的长度，即第一长度(第一名义PUSCH的长度)。K个名义PUSCH中的第一个名义PUSCH可以是指第一控制信息所指示的名义PUSCH。第一控制信息所指示的第一名义PUSCH的结束时刻是由第一控制信息所指示的第一名义PUSCH的起始时刻和第一名义PUSCH的长度L确定的。或者，第一控制信息所指示的第一名义PUSCH的结束时刻是由第一控制信息所指示的第一名义PUSCH的起始时刻、第一名义PUSCH的长度L和第一控制信息所指示的第一名义PUSCH的起始时刻之后的非上行符号确定的。
当2≤i≤K时，K个名义PUSCH中的第i个名义PUSCH的起始时刻由第一个名义PUSCH的起始时刻、第一名义PUSCH的长度、第一个名义PUSCH的起始时刻之后的非上行符号确定的。K个名义PUSCH中的第i个名义PUSCH的长度对应上述时域资源分配字段中的第一名义PUSCH的长度。K个名义PUSCH中的第i个名义PUSCH的结束时刻由第一个名义PUSCH的起始时刻、第一名义PUSCH的长度、第一个名义PUSCH的起始时刻之后的非上行符号确定的。
名义PUSCH的结束时刻晚于对应于第一控制信息所指示的第一名义PUSCH的结束时刻。
在一些实施例中，若第一控制信息指示的第一名义PUSCH的起始时刻至第一时间单元的结束时刻之间不包括非上行符号，名义PUSCH的起始时刻S可以表示为S0+(i-1)*L。名义PUSCH的结束时刻可以表示为S0+i*L。其中，S0表示第一控制信息指示的K个名义PUSCH中的第1个名义PUSCH的起始时刻。
在另一些实施例中，若第一控制信息指示的第一名义PUSCH的起始时刻至第一时间单元的结束时刻之间包括至少一个有效上行符号和至少一个非上行符号，名义PUSCH的起始时刻S可以表示为S0+(i-1)*L+N_NUL。名义PUSCH的结束时刻可以表示为S0+i*L+N_NUL_2。N_NUL表示K个名义PUSCH中第一个名义PUSCH的起始时刻与所述名义PUSCH的起始时刻之间的非上行符号数，N_NUL_2表示K个名义PUSCH中第一个名义PUSCH的起始时刻与所述名义PUSCH的结束时刻之间的非上行符号数。
特别的，K个名义PUSCH中第一个名义PUSCH的起始时刻S可表示为S0+N_NUL，S0+N_NUL可以表示所述K个名义PUSCH中的第一个名义PUSCH的起始时刻与所 述第一控制信息指示的起始时刻之间有非上行符号的存在。
可理解的，从第一时间单元内的第一符号开始，根据第一长度在第一时间单元的时域资源上发送第一PUSCH集合。第一名义PUSCH的起始时刻为第一符号。第一时间单元的结束时刻在名义PUSCH的起始时刻与名义PUSCH的结束时刻之间。
在一些实施例中，第一时间单元的结束时刻在名义PUSCH的结束时刻之后。第一PUSCH集合对应的时域资源为在第一时间单元内第一名义PUSCH对应的全部时域资源。示例的，如图15所示。假设K＝2，第一名义PUSCH的长度L为4个符号，第一名义PUSCH的起始符号为符号5。在时隙n中的第5个符号至第8个符号上第一次发送第一名义PUSCH。在时隙n中的第9个符号至第12个符号上第二次发送第一名义PUSCH。第一PUSCH集合包括第一PUSCH和第二PUSCH。网络设备在第一PUSCH对应的资源上接收第一PUSCH，以及在第二PUSCH对应的资源上接收第二PUSCH。
在另一些实施例中，第一时间单元的结束时刻在名义PUSCH的结束时刻之前。第一PUSCH集合对应的时域资源为在第一时间单元内第一名义PUSCH对应的部分时域资源。终端设备还可以发送第二PUSCH集合，第二PUSCH集合对应的时域资源是根据第一符号和第一长度确定的在时间单元的结束时刻之后的时域资源。
示例的，如图16所示。假设第一名义PUSCH的长度L为4个符号，第一名义PUSCH的起始符号为符号5。在时隙n中的第5个符号至第8个符号上映射第一名义PUSCH，以及在时隙n中的第13个符号至第14个符号和时隙n+1中的第1个符号至第2个符号上映射第一名义PUSCH。
其中，由于时隙n中的第9个符号至第12个符号是下行符号，所以跳过第9个符号至第12个符号，推迟映射第一名义PUSCH，在下行符号后的第一个上行符号(时隙n的第12个符号)开始继续映射第一个名义PUSCH，即在时隙n中的第13个符号和第14个符号继续映射第一名义PUSCH。
另外，第一名义PUSCH横跨时隙边界，时隙边界将第一名义PUSCH切分为两个PUSCH，映射在时隙n的第13个符号至第14个符号上的PUSCH可以称为第二PUSCH，映射在时隙n+1的第1个符号和第1个符号上的PUSCH可以称为第三PUSCH。第一PUSCH集合包括第一PUSCH和第二PUSCH。第二PUSCH集合包括第三PUSCH。第一PUSCH和第二PUSCH位于同一个上行区域。
终端设备在时隙n中的第5个符号至第8个符号上发送第一PUSCH、在时隙n中的第13个符号至第14个符号上发送第二PUSCH和在时隙n+1中的第1个符号至第2个符号上发送第三PUSCH。第一PUSCH、第二PUSCH和第三PUSCH上承载相同的传输块。网络设备在第一PUSCH集合对应的资源上接收第一PUSCH集合，以及在第二PUSCH集合对应的资源上接收第二PUSCH集合。
在第五种可能的实现方式中，终端设备认为动态指示的R16PUSCH传输重复次数去使能，意味着自己被指示不再支持R16传输机制。同时，网络设备为R16传输机制配置的时域资源分配表格也不可用。此时，网络设备可以为终端设备配置一个支持R15传输机制的时域资源分配表格。或者，终端设备采用配置给DCI格式0_0的时域资源分配分配表格和上行调度授权的控制信息确定PUSCH的时域资源。因为DCI格式0_0称为回退DCI，不支持R16的传输机制，所以配置给回退DCI的时域资源分配表 格中的时域资源都可以用于R15传输。回退DCI(fallback DCI)是指在初始化接入状态时或小区切换时传输的DCI。
所述上行调度授权的控制信息为下行控制信息，该控制信息可以为DCI格式0_1或者DCI格式0_2。该控制信息的循环冗余码校验(cyclic redundancy check，CRC)可以由小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)、配置调度无线网络临时标识(Configured scheduling-cell radio network temporary identifier，CS-RNTI)和调制编码方式-小区无线网络临时标识(Modulation and coding scheme-Cell-Radio network temporary identifier，MCS-C-RNTI)中的至少一种RNTI加扰。
DCI中的“DCI格式标识”(Identifier for DCI格式s)信息域用于标识DCI格式。所述DCI格式0_1为非回退DCI，非回退DCI不同于回退DCI(DCI格式0_0)。RNTI用于加扰DCI格式0_0。RNTI包括寻呼-无线网络临时标识(Paging-Radio network temporary identifier，P-RNTI)、随机接入-无线网络临时标识(Random access-Radio network temporary identifier，RA-RNTI)、系统消息-无线网络临时标识(System information-Radio network temporary identifier，SI-RNTI)、临时小区无线网络临时标识(Temporary cell-Radio network temporary identifier,TC-RNTI)以及C-RNTI、CS-RNTI和MCS-RNTI。DCI格式0_0可用于调度承载寻呼信息、初始接入响应信息或系统消息的下行共享物理信道(physical downlink shared channel，PDSCH)。而DCI格式0_1用于连接态下调度PDSCH。DCI格式0_1承载的控制信息比DCI格式0_0更多。DCI格式0_1包括载波指示、BWP指示器、下行链路分配指示、SRS资源指示、预编码信息和层数、SRS请求、CSI请求、编码块传输指示、天线端口、速率匹配指示、DMRS序列初始化和UL-SCH指示中至少一个。
DCI格式0_2为紧凑DCI(compact DCI)，紧凑DCI不同于另外两种DCI格式的特征在于，其大多数DCI域都可以配置为0比特，用于节省DCI开销，同时提高DCI传输的可靠性。
图17为本申请实施例提供的一种发送物理上行共享信道的方法流程图。这里以网络设备和终端设备为例进行说明。假设第一传输方式为3GPP R15传输机制。第二传输方式为R15传输机制。如图17所示，该方法可以包括：
S1701、网络设备向终端设备发送第一信息。
S1702、终端设备接收网络设备发送的第一信息。
在一些实施例中，第一信息指示第一传输方式或第二传输方式。第一传输方式为在一个时间单元的时域资源上传输M个名义PUSCH、或者在连续可用的多个时间单元的时域资源上传输M个名义PUSCH，M个名义PUSCH包括第一名义PUSCH，第二传输方式为在K个连续可用的时间单元上重复发送K个第一名义PUSCH，一个时间单元发送一个第一名义PUSCH，M为大于或等于1的整数，K为大于或等于1的整数。
当第一信息指示第二传输方式，终端设备认为动态指示的R16PUSCH传输重复次数去使能，意味着自己被指示不再支持R16传输机制。所述方法还包括S1703和S1704。
S1703、终端设备根据第二传输方式向网络设备发送第一名义PUSCH。
在一些实施例中，终端设备从第一时间单元内的第一符号开始，根据第一长度对第一名义PUSCH进行单次传输。具体的，从第一时间单元内的第一符号开始，根据第一长度在第一时间单元的时域资源上发送第一名义PUSCH，第一名义PUSCH对应的时域资源为在第一时间单元内第一名义PUSCH对应的全部或部分时域资源，第一名义PUSCH的起始时刻为第一符号，第一时间单元的结束时刻在第一名义PUSCH的起始时刻与第一名义PUSCH的结束时刻之间。若第一名义PUSCH的长度大于第一时间单元的长度，在第一时间单元的结束时刻之后不发送第一名义PUSCH。
具体的，可以参考图11的阐述。
S1704、网络设备根据第二传输方式接收终端设备发送的第一名义PUSCH。
