Description

一种无线通信方法、终端及网络设备 技术领域
本申请涉及通信技术领域，尤其涉及一种无线通信方法、终端和网络设备。
背景技术
网络设备将物理下行共享信道(physical downlink shared channel，PDSCH)承载的下行数据发送至终端。终端收到后，需要向网络设备发送PDSCH的混合自动重传请求(hybrid automatic repeat request，HARQ)，以告知网络设备下行数据是否接收正确。HARQ反馈信息承载于物理上行控制信道(physical uplink control channel，PUCCH)资源上。在发送HARQ反馈信息之前，终端需要先确定用于发送HARQ反馈信息的PUCCH时域资源。
目前采用现有的PUCCH资源分配方式确定的PUCCH资源主要用于单播传输，即网络设备向一个终端做数据传输，一个物理下行控制信道(physical downlink control channel，PDCCH)上承载的下行控制信息(downlink control information，DCI)只能确定一个PUCCH时域资源。而广播/多播/组播传输是由网络设备向多个UE做数据传输场景下，可能造成接收同一广播/多播/组播传输的终端在相同时域资源上发送承载HARQ反馈信息的PUCCH，导致网络设备在该时域资源上接收到过大的数据量，引起系统负载过大，系统性能降低。
发明内容
为了解决上述技术问题，本申请实施例中提供了一种无线通信方法、终端和网络设备，用于广播/多播/组播传输下为终端合理分配PUCCH资源，以达到降低系统负载，提高系统性能的技术目的。具体方案如下。
第一方面，本申请实施例中提供了一种无线通信方法，包括：首先，终端接收指示信息，该指示信息用于指示时域偏移量；其次，终端接收物理下行控制信道PDCCH，PDCCH用于调度物理下行共享信道PDSCH，物理上行控制信道PUCCH用于承载PDSCH对应的混合自动重传请求HARQ-ACK；最终，终端根据第一参数、第二参数和时域偏移量，确定PUCCH时域资源，其中第一参数为PDSCH的时间单元与承载HARQ-ACK的时间单元的偏移，第二参数是PDCCH中承载的PUCCH资源指示信息。可选地，第一参数承载于DCI中，或者第一参数承载于无线资源控制RRC信令中。
在上述第一方面的技术方案中，该指示信息用于指示时域偏移量，该时域偏移量用于确定PUCCH时域资源，对于任意一个终端而言，终端的时域偏移量均是专用的，独立配置的，互不影响的，因此，终端根据时域偏移量、第一参数和第二参数确定PUCCH时域资源，可以使得终端的PUCCH时域资源在时域上是非全部重叠的、错开的，可以减少同一时刻终端传输的PUCCH数量，从而降低系统负载，提高系统性能。

第二方面，本申请实施例中提供了一种无线通信方法，包括：首先，网络设备发送指示信息，指示信息用于指示时域偏移量；其次，网络设备发送物理下行控制信道PDCCH，PDCCH用于调度物理下行共享信道PDSCH，物理上行控制信道PUCCH用于承载PDSCH对应的混合自动重传请求HARQ-ACK；最后，网络设备根据第一参数、第二参数以及时域偏移量，确定PUCCH时域资源，其中第一参数为PDSCH的时间单元与承载HARQ-ACK时间单元的偏移，第二参数是PUCCH资源指示信息。可选地，第一参数承载于DCI中，或第一参数承载于RRC信令中。
在上述第二方面的技术方案中，网络设备为终端配置时域偏移量，该时域偏移量用于确定PUCCH时域资源，对于任意一个终端而言，网络设备为每个终端配置的时域偏移量均是 专用的，独立配置的，互不影响的，因此，网络设备根据时域偏移量、第一参数和第二参数确定PUCCH传输资源，可以使得终端的UCCH时域资源在时域上是非全部重叠的、错开的，可以减少同一时刻终端传输的PUCCH数量，从而降低系统负载，提高系统性能。

Figure PCTCN2019119162-appb-000001
为了便于理解本申请实施例中所述的无线通信方法，下面将结合具体的实施例对本申请实施例中的技术方案进行详细说明，请参阅图2，为本申请实施例中提供的PUCCH资源确定方法的一个实施例示意图。
如图2所示，本申请实施例中提供的无线通信方法的一个实施例，包括：
201、网络设备向终端发送指示信息，该指示信息用于指示时域偏移量。
举例说明，时域偏移量用于确定PUCCH时域资源。PUCCH用于承载PDSCH对应的反馈信息，PDSCH被PDCCH调度。可选地，PDSCH对应的反馈信息可以为混合自动请求HARQ-ACK，还可以是PUCCH上承载的其他信息。
时域偏移量是基于第一参数或第二参数的偏移量。具体来说，一方面，时域偏移量为第一参数对应的偏移量，其中第一参数是PDSCH占用的时间单元与承载混合自动重传请求HARQ-ACK的时间单元的偏移，一般来说，HARQ-ACK是由PUCCH承载的。另一方面，时域偏移量为第二参数对应的偏移量，其中第二参数是PUCCH资源指示信息，换言之，第二参数是PUCCH资源指示信息指示的，或，第二参数是由根据PUCCH资源指示信息得到的。在本申请实施例中，指示信息可以只指示第一参数对应的偏移量，或第二参数对应的偏移量；指示信息还可以同时指示第一参数对应的偏移量，和第二参数对应的偏移量，对此本申请不做任何限制。
下面将就时域偏移量分别为第一参数对应的偏移量和第二参数对应的偏移量做出示例性的说明，应理解，时域偏移量也可以与两者结合或以其它形式指示以使得UE确定资源，再此不做限定。
在一些可能的实施例方式中，若时域偏移量为第一参数对应的偏移量，第一参数可以表示为K1。K1可以承载于DCI中，如承载于DCI中的PDSCH到HARQ反馈定时指示器PDSCH-to-HARQ_feedback timing indicator信息域中，该域亦可称为K1域；或，K1也可以通过高层信令配置的，可选地，配置该K1的高层信令为dl-DataToUL-ACK。第一参数对应的偏移量可以表示为offset-K1，offset-K1可以承载于终端专用的RRC信令中；或，offset-K1还可以承载于高层参数中，可选地，高层参数为PUCCH-format X指示的参数，其中X可以是0，1，2，3，4等；或，offset-K1也可以承载于PDCCH上第一参数所在的DCI域中，或，offset-K1也可以承载于PDCCH上新增加的DCI域中。需要说明的是，上述的PUCCH format X是不同的PUCCH格式，其中不同的PUCCH格式配置的PUCCH时频资源不同，PUCCH format 0-4承载的上行控制信息类型和上行控制信息的负载范围也不同。具体 来说，X的取值可以为0，1，2，3，4，PUCCH format 0、PUCCH format 1、PUCCH format2、PUCCH format 3和PUCCH format 4指示的高层参数分别映射相应PUCCH格式对应的时频资源。PUCCH format 0、PUCCH format 1、PUCCH format 2、PUCCH format 3和PUCCH format4中参数值相同的高层参数分别对应的时频资源均不相同。
接下来对本申请实施例中所述的DCI进行说明，本申请实施例中所述的DCI可以为回退DCI，也可以为非回退DCI，其中回退DCI的格式为1_0即DCI format 1_0，非回退DCI为1_1即DCI format 1_1，DCI中的DCI格式标识identifier for DCI formats信息域用于标识DCI格式。
其中，回退DCI是指在初始化接入状态时或小区切换时传输的DCI，用于加扰DCI format 1_0的无线网络临时标识RNTI包括：寻呼无线网络临时标识(page-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(temporal cell-radio network temporary identifier，TC-RNTI)以及小区无线网络临时标识C-RNTI、配置调度无线网络临时标识CS-RNTI、和调制编码方式小区无线网络临时标识MCS-C-RNTI。DCI format 1_0可用于调度承载寻呼信息，初始接入响应信息、系统消息的PDSCH。
另一方面，DCI format 1_1为非回退DCI，用于连接态下调度PDSCH。相比于DCI format1_0，DCI format 1_1承载的控制信息更丰富，可以包括：载波指示、部分载波带宽(bandwidth part，BWP)指示器、物理资源块(physical resource block，PRB)绑定尺寸指示器、速率匹配指示器、零功率信道状态信息参考信号(channel state information reference signal，CSI-RS)触发器、探测参考信号(sounding reference signal，SRS)请求、天线端口、和传输配置指示器。
如上文所述，第一参数对应的偏移量承载于K1域中，则可以通过扩展K1域以承载第一参数对应的偏移量。具体地，K1域的扩展方式可以是：在K1域中新增字段，以使得新增字段指示第一参数对应的偏移量。具体地，将K1域由a个比特扩展为(a+b*c)个比特，其中a可以为0，1，2，3中的一个，c为接收所述广播/多播/组播PDCCH的终端数量，b为指示给一个终端的第一参数对应的偏移量的比特数，新增的(b*c)个比特可以按照预设顺序指示相应终端的第一参数对应的偏移量，其中预设顺序可以是按终端标识升序，也可以是按终端标识降序，还可以是通过预设的映射表进行指示，其中，映射表为新增的(b*c)个比特与终端标识之间的对应关系，以指示每个终端对应哪些个比特位。
例如，a、b、c的取值分别为3、2、5，则K1域由3个比特扩展为(3+2*5)个比特，扩展后的K1域可以指示2个终端的第一参数对应的偏移量，并且，每个第一参数对应的偏移量可以使用5个比特进行指示。新增的10个比特中的前5个比特用于指示第一个终端中的第一参数对应的偏移量，后5个比特用于指示第二个终端中的第一参数对应的偏移量。
在一些可能的实施例方式中，若时域偏移量为第二参数对应的偏移量，其中第二参数可以承载于DCI中，如第二参数可以通过DCI的PUCCH资源指示器(PUCCH resource  indicator,PRI)域指示的比特位表示的状态映射得到，第二参数可以表示为PRI。PRI域可以是3个比特，表征8个状态，这8个状态分别对应高层信令(pucch-ResourceId)表示的资源列表(reourceList)中的PUCCH时域资源。相应地，第二参数对应的偏移量可以表示为offset-PRI，offset-PRI可以承载于终端专用的RRC信令中，或offset-PRI也可以承载于PDCCH上第二参数所在的PRI域、ACK/NACK资源指示域中，或offset-PRI也可以承载于PDCCH上新增加的DCI域中。需要说明的是，与上述第一参数的偏移量类似，第二参数的偏移量也可以承载于高层参数中。
具体地，若第二参数对应的偏移量承载于第二参数所在的PRI域中，与上述的第一参数对应的偏移量承载于第一参数所在的DCI域中类似，可以对PRI域进行扩展以承载第二参数对应的偏移量。其具体的PRI域扩展方式可参阅上述K1域的扩展方式，此处不再赘述。
上述的时域偏移量的不同承载方式对应不同的指示信息发送方式。若时域偏移量承载于高层信令中，网络设备通过高层信令发送对应的指示信息；若时域偏移量承载于高层参数中，网络设备通过高层参数发送对应的指示信息；若时域偏移量承载于第一参数或第二参数所在的DCI域中，网络设备通过PDCCH发送对应的指示信息。
下面对指示信息发送方式进行详细说明，指示信息发送方式可以包括但不限于以下发送方式：
第一种指示信息发送方式：网络设备通过高层信令向终端发送指示信息。
网络设备通过高层信令向终端发送指示信息，该指示信息用于配置时域偏移量。可选地，高层信令为RRC信令。例如，网络设备向终端发送一个RRC信令，该RRC信令中包括多个信元，每个信元中包括一个时域偏移量并且只与一个终端标识UE ID相关联，使得每个终端只解读与自己标识相关的配置信息，不解读上述RRC信令中与其他终端相关联的配置信息。进一步可选地，RRC信令为终端专用的UE-dedicated RRC信令。例如，网络设备向终端发送一个UE-dedicated RRC信令，该UE-dedicated RRC信令中只包括一个与自身相关联的信元，使得终端只能接收到与自身相关的承载偏移量的配置信息，无法接收到与其他UE相关的承载偏移量的配置信息。
需要说明的是，网络设备通过高层参数发送指示信息与上述第一种指示信息发送方式类似，其具体描述可参阅第一种指示信息发送方式中的相关描述，此处不再赘述。
第二种指示信息发送方式：网络设备通过PDCCH向终端发送指示信息。
在上述第二种指示信息发送方式中，网络设备通过PDCCH向终端发送指示信息可以扩展DCI域的字段，使得扩展后的字段为指示信息，用于指示时域偏移量。扩展DCI域的字段可以包括但不限于以下扩展方式：DCI域扩展方式一：在DCI中增加新的信息域，以指示时域偏移量。
举例说明，在广播/多播/组播PDCCH的DCI中新增加以下至少一种信息域：第一信息域、第二信息域；其中第一信息域和第二信息域中均包括n个子信息域，n为接收广播/多播/组播PDCCH的终端数量。第一信息域中的每一个子信息中中携带第一参数对应的偏移量且只与一个UE ID相关联；第二信息域中携带第二参数对应的偏移量且只与一个UE ID相 关联。
上述的扩展方式一中包括以下三种情况：只在广播/多播/组播PDCCH的DCI中新增第一信息域，只在广播/多播/组播PDCCH的DCI中新增第二信息域，以及在广播/多播/组播PDCCH的DCI中新增同时新增加第一信息域、第二信息域。下面分别对前面两种情况进行详细说明，最后一种情况与前两种情况类似，可参阅相关描述。
在广播/多播/组播PDCCH的DCI域中包括第一信息域的情况下，由于广播/多播/组播PDCCH用于网络设备向多个终端发送相同的信息，则接收该PDCCH的第一终端可从第一信息域中的第一子信息域中获取第一偏移量，用于确定第一PUCCH的时域资源，以及接收该PDCCH的第二终端可从第一信息域中的第二子信息域中获取第二偏移量，用于确定第二PUCCH时域资源。第一偏移量和第二偏移量分别为第一终端和第二终端各自专用的第一参数对应的偏移量，第一偏移量和第二偏移量是不相关的，因此第一终端和第二终端分别确定的第一PUCCH和第二PUCCH的时域资源不同。
在若广播/多播/组播PDCCH的DCI域中包括第二信息域情况下，由于广播/多播/组播PDCCH用于网络设备向多个终端发送相同的信息，则接收该PDCCH的第三终端可从第二信息域中的第三子信息域中获取第三偏移量，用于确定第三PUCCH的时域资源，接收该PDCCH的第四终端可从第四子信息域中获取第四偏移量，用于确定第四PUCCH时域资源。第三偏移量和第四偏移量分别为第三终端和第四终端各自专用的第二参数对应的偏移量，第三偏移量和第四偏移量是不相关的，因此第三终端和第四终端分别确定的第三PUCCH和第四PUCCH的时域资源不同。
DCI域扩展方式二：对DCI中的现有信息域新增字段，以指示时域偏移量。
在广播/多播/组播PDCCH中对第一参数、第二参数所在在信息域进行扩展，以指示相应的时域偏移量。具体地，若时域偏移量为第一参数对应的偏移量，则在第一参数所在的信息域中新增加字段，新增加的字段用于指示c个字段，每一个字段中包括b个比特，一个字段指示一个第一参数对应的偏移量。若时域偏移量为第二参数对应的偏移量，则在第二参数所在的信息域中新增加字段，新增加的字段用于指示c个字段，每一个字段中包括b个比特，一个字段指示一个第二参数对应的偏移量。其中，类似地，c为接收所述广播/多播/组播PDCCH的终端数量，b为指示给一个终端的第一参数或第二参数对应的偏移量的比特数。
可选地，按照上述方式对K1域、PRI域中至少一个信息域进行扩展，K1域的具体扩展方式如上述步骤201中所述，PRI域的扩展方式与K1域的扩展方式类似，具体来说：将PRI域由d个比特扩展为(d+b*c)，其中d为现有PRI域的比特数，与上述K1域扩展中类似，c为接收所述广播/多播/组播PDCCH的终端数量，b为指示给一个终端的第二参数对应的偏移量的比特数。例如，d，b，C的取值为4、3、4，则PRI域由4个比特扩展为(4+3*4)个比特，扩展后的PRI域可以指示3个终端的第二参数对应的偏移量，并且每个第二参数对应的偏移量使用4个比特进行指示。需要说明的是，本申请实施例中还可以同时对K1域和PRI域进行扩展，以通过DCI同时指示第一参数对应的偏移量和第二参数对应的偏移量，其中K1域和PRI域的扩展方式如上所述。
在上述两种DCI域扩展方式中需要说明的是，扩展的第一信息域中的子信息域数目、第二信息域中的子信息域数目、K1域中新增的字段数目、PRI域中新增加的字段数目可以小于或等于c个，容易理解，当c个终端中可能存在第一参数对应的偏移量是相同的情况，也可能存在第二参数对应的偏移量是相同的情况，此时可以用一个子信息域或一个新增字段指示第一参数或第二参数对应的偏移量相同的两个或多个终端。例如，第一参数对应的偏移量是由终端标识UE ID对2取模得到的，则c个子信息域便可以是实现对c个终端中第一参数对应的偏移量的指示。比如有10个终端，最多有10个偏移量，如果对2取模，则有5个偏移量就可以了。
在本申请的一些实施例中，时域偏移量中包括至少一个时间单元，该时间单元的单位可以是：时隙、子时隙、微时隙、或正交频分复用符号等，也可以是其它度量单位。可选地，时域偏移量可以用于表征对时隙、子时隙、微时隙、或符号级别的时域长度为基本单位的偏移，一个实施例中，也可以是相对单位的偏移。
需要说明的是，若网络设备通过高层信令向终端发送指示信息，则网络设备还需执行下面的步骤202，若网络设备通过PDCCH向终端发送指示信息，则网络设备可以不再重复执行下面的步骤202。
可选地，在步骤201之前还可以包括：网络设备确定时域偏移量。在一种可能的确定时域偏移量的方式中，时域偏移量是由终端标识得到的。具体的，每个终端专用的时域偏移量均由每个终端对应的终端标识得到的。可选地，时域偏移量是由终端标识取模得到。例如，终端标识为1，3，5，7，9；对终端标识对4取模后得到的时域偏移量依次是：1，3，1，3，1。需要说明的是，由终端标识计算得到时域偏移量的计算方式包括但不限于取模运算，还可以使用其他类似的计算方式(如取余运算)或对应关系，对此本申请不做任何限制。
202、网络设备向终端发送PDCCH，该PDCCH用于调度物理下行共享信道PDSCH。
作为一个示例，PDCCH中包括K1域，该K1域用于指示第一参数。作为又一个示例，PDCCH中包括PRI域，该PRI域中携带有第二参数，或，该PRI域用于指示第二参数。需要说明的是，如果PDCCH中不包括K1域，则网络设备还需要通过高层信令或高层参数为终端配置第一参数。例如，网络设备通过RRC信令为终端配置第一参数。
在本申请的一些实施例中，如上所述，PDCCH中还可以包括指示信息，例如时域偏移量。若PDCCH没有包括时域偏移量，则网络设备通过高层信令向终端发送指示信息；具体的可参阅上述步骤201中的第一种指示方式中的描述。需要说明的是，当PDCCH中携带时域偏移量时，PDCCH可以通过上述的第一信息域或第二信息域进行指示时域偏移量，也可以复用现有PDCCH中的信息域，还可以在现有PDCCH中的信息域中新增加字段专门用于指示确定PUCCH资源的时域偏移量，对此本申请中不做任何限制。
本申请实施例中，PDCCH是用于广播/多播/组播传输的。具体来说，UE根据第一参数、第二参数和偏移量确定承载反馈信息HARQ的PUCCH时域资源，可以使得UE接收的与PUCCH对应的PDCCH满足PDCCH是终端在公共搜索空间中检测得到的，或，满足PDCCH是由组无线网络临时标识G-RNTI加扰的。在广播/多播/组播传输中，终端根据第一参数即K1域的 值确定PUCCH所在的时间单元，并根据第二参数即PRI域的值及其偏移量offset-PRI确定PUCCH时域资源；或者，终端根据第一参数即K1域的值及其偏移量offset-K1确定PUCCH所在的时间单元，并根据第二参数即PRI域的值确定PUCCH时域资源。
本申请实施例中，若PDCCH是用于单播传输的。具体来说，PDCCH是由终端专用的无线网络临时标识RNTI加扰的。可选的，终端专用的RNTI可以包括但不限于：C-RNTI、CS-RNTI和MCS-C-RNTI。在单播传输中，终端不根据时域偏移量确定PUCCH时域资源。具体地，终端根据K1域的值确定PUCCH所在的时间单元，并根据PRI域的值确定PUCCH时域资源。
在一些可能的实施例方式中，终端根据第一参数及其偏移量确定PUCCH所在的时间单元可以是终端根据第一参数对应的比特位指示的状态与第一参数的参数值之间的关联关系确定第一参数的参数值，同样地，终端可以根据第一参数对应的偏移量对应的比特位状态与第一参数对应的偏移量的参数值之间的关联关系确定第一参数对应的偏移量的参数值。进而，终端根据第一参数和第一参数对应偏移量确定PUCCH所在的时间单元。
示例性地，如表1所示，第一参数的比特位指示的状态与参数值之间关联关系，表2所示，为第一参数对应的偏移量的比特位指示的状态与参数值之间关联关系。在表1和2中第一参数以及第一参数对应的偏移量均以3比特为例进行说明，在本申请实施例中指示第一参数的比特位数目、以及指示第一参数对应的偏移量的比特位数目之间可以相同，也可以不相同。

上述实施例方式中，终端根据第一参数和第一参数对应偏移量确定PUCCH所在的时间 单元可以包括：终端直接根据第一参数和第一参数对应偏移量确定PUCCH所在的时间单元，或，终端先根据第一参数和第一参数对应偏移量中至少一个参数值进行换算并基于换算结果确定PUCCH所在的时间单元。
举例说明，以上述表1和2为例。在一种示例中，若指示第一参数的比特位状态为000，指示第一参数对应的偏移量的比特位状态为001，则终端分别确定第一参数为8，第一参数对应的偏移量为2。若第一参数对应的时间单元为时隙，第一参数对应的时间单元为子时隙，此时，终端可以将时隙8中的子时隙2确定为PUCCH所在的时域资源。若第一参数及其偏移量对应的时间单元均为时隙或子时隙，此时，终端也可以将时隙10，或子时隙10确定为PUCCH所在的时间单元。容易理解，本申请中所述的比特位状态与逻辑值含义相同，一个逻辑值对应一种比特位状态。
在另一种示例中，若指示第一参数的比特位状态为000，指示第一参数对应的偏移量的比特位状态为001，则终端分别确定第一参数为8，终端确定第一参数对应的偏移量为2，并对第一参数对应的偏移量对2取模得到取模结果为0。类似的，若第一参数对应的时间单元为时隙，第一参数对应的偏移量对应的时间单元为子时隙，此时，终端可以将时隙8中的子时隙0确定为PUCCH所在的时域资源，容易理解，子时隙0可以表示一个时隙中的第一个子时隙。若第一参数及其偏移量对应的时间单元均为时隙或子时隙，此时，终端也可以将时隙8，或子时隙8确定为PUCCH所在的时域资源。
在一些可能的实施例方式中，类似地，终端根据第二参数及其偏移量确定PUCCH所在的时间单元可以是终端根据第二参数对应的比特位指示的状态与第二参数的参数值之间的关联关系确定第二参数的参数值，同样地，终端可以根据第二参数对应的偏移量对应的比特位状态与第二参数对应的偏移量的参数值之间的关联关系确定第二参数对应的偏移量的参数值。进而，终端根据第二参数和第二参数对应偏移量确定PUCCH时域资源。需要说明的是，此处终端根据第二参数和第二参数对应的偏移量确定PUCCH时域资源与上述根据第一参数和第一参数对应的偏移量确定PUCCH所在的时间单元。
终端根据第二参数及其偏移量确定PUCCH时域资源，可以包括：终端将第二参数对应的比特位的逻辑值与偏移量对应的比特位的逻辑值相加得到PUCCH时域资源；或，终端将第二参数对应的比特位的逻辑值和偏移量对应的比特位的逻辑值进行换算后相加得到PUCCH时域资源，如对逻辑值从二进制转换为10进制后对q取模或取余得到PUCCH时域资源，其中q为正整数。例如，第二参数对应的比特位的逻辑值为2，第二参数对应的偏移量对应的比特位的逻辑值为1，则终端可以根据两个逻辑值的和(2+1)确定PUCCH时域资源，或，终端也可以根据两个逻辑值转换为10进制后对2取模得到的值1，确定PUCCH时域资源。
在本申请的一些实施例中，终端接收调度多播传输的PDCCH之后，网络设备向终端发送PDCCH调度的PDSCH。PDCCH中还携带由网络设备发送PDSCH的时域信息：PDCCH所在的时间单元与PDSCH所在时间单元的偏移，其中时间单元可以为时隙、子时隙、微时隙、正交频分复用符号、子帧。
203、终端根据第一参数、第二参数和时域偏移量，确定PUCCH时域资源。
下面将分别就基于第一参数、第二参数和时域偏移量确定PUCCH时域资源的两种具体方式进行详细说明。
一种PUCCH资源确定方式，若时域偏移量与第一参数对应，则终端确定PUCCH时域资源，可以执行以下步骤一至步骤三。
步骤一、终端根据第一参数和第一参数对应的偏移量确定发送PDSCH对应的反馈信息(如HARQ-ACK)的PUCCH所在的时间单元。
例如，第一参数及其偏移量对应的时间单元均以时隙为例，PDCCH指示终端在时隙n上发送PDSCH，第一参数为k，若第一参数对应的时域偏移量为m，m和n为整数，则终端确定发送HARQ-ACK的PUCCH所在的时间单元为时隙(n+k+m)；若第一参数对应的时域偏移量为i，则终端确定发送HARQ-ACK的PUCCH所在的时间单元为时隙(n+k+i)。
示例性地，时间单元以子时隙为例，上述的步骤一具体可以是：
首先，终端通过DCI中的K1域的值或者RRC信令配置的K1值确定发送HARQ的PUCCH所在的子时隙，其中K1域用于指示PDSCH所在的子时隙到HARQ所在子时隙的偏移。其次，终端根据新增的子信息域或字段中获取第一参数的偏移量即K1的偏移量；最终，终端根据K1域的值和K1的偏移量确定PUCCH时域资源。例如，如果UE检测到PDCCH调度PDSCH在子时隙n发送，若DCI中K1域的值为1，K1的偏移量为1，则UE确定在子时隙(n+1+1)中发送承载反馈信息HARQ-ACK的PUCCH；但若该DCI中不含K1域，则终端通过高层参数获取第一参数，可选地，高层参数为dl-DataToUL-ACK，在子时隙(n+k+1)中发送承载反馈信息HARQ-ACK的PUCCH，其中k是由高层参数配置的。
步骤二、终端选择PUCCH资源集合。一个实施例中，终端根据需要传输的HARQ-ACK信息的负载大小(payload)选择PUCCH资源集合。
示例性地，上述的步骤二具体可以包括：终端根据时隙中需要传输的HARQ-ACK信息的负载大小O UCI选择PUCCH资源集合。一个终端最多可以配置4个PUCCH资源集合。其中第一个PUCCH资源集合中最多支持32个PUCCH资源，其余的PUCCH资源集合最多支持8个PUCCH资源。如果O UCI≤2，则选择第一个PUCCH资源集合，pucch-ResourceSetId＝0；如果2＜O UCI≤N 2，UE选择第二个PUCCH资源集合，pucch-ResourceSetId＝1，其中N 2为高层参数配置的，如果高层参数没有配置，则N 2值为1706；如果N 2＜O UCI≤N 3，UE选择第三个PUCCH资源集合，pucch-ResourceSetId＝2，其中N 3为高层参数配置的，如果高层参数没有配置，则N 3值为1706；如果N 3＜O UCI≤1706，UE选择第四个PUCCH资源集合，pucch-ResourceSetId＝3，其中N 3为高层参数配置的，如果高层参数没有配置，则N 3值为1706。
步骤三、终端根据第二参数在步骤二确定的PUCCH资源集合中确定一个PUCCH资源用于发送HARQ-ACK信息。
示例性地，上述步骤三具体可以包括：终端从PRI域中获取第二参数的值，第二参数的值对应PUCCH资源索引，每个索引对应一个PUCCH资源，PUCCH资源由高层参数预先配置；终端根据第二参数的值从上述步骤二确定的PUCCH资源集合中确定相应的PUCCH时域资源。例如，终端获取的第二参数的值为0，上述步骤二中确定的PUCCH资源集合为支持 32个PUCCH资源的第一个PUCCH资源集合，则终端确定用于发送反馈信息的PUCCH资源为第一个PUCCH资源集合中的第一个PUCCH资源。
另一种PUCCH资源确定方式，若时域偏移量与第二参数对应，则终端确定PUCCH时域资源，可以执行以下步骤四至步骤六。
步骤四、终端根据第一参数确定发送PDSCH对应的反馈信息(如HARQ-ACK)的PUCCH所在的时间单元。
例如，第一参数及其偏移量对应的时间单元均以时隙为例，PDCCH指示终端在时隙n上发送PDSCH，第一参数为k，则终端确定发送HARQ-ACK的PUCCH所在的时间单元为时隙(n+k)。
又如，第一参数及其偏移量对应的时间单元均以子时隙为例，上述的步骤四具体可以是：PDCCH指示终端在子时隙n上发送PDSCH，终端通过DCI中的K1域或者RRC信令配置的K1值确定第一参数的值为k，其中K1域用于指示PDSCH所在的子时隙到HARQ所在子时隙的偏移；进而终端确定发送HARQ的PUCCH所在的子时隙为子时隙(n+k)。
步骤五、终端根据需要传输的HARQ-ACK信息的负载大小(payload)选择PUCCH资源集合。
步骤五与上述步骤二类似，其相关描述可参阅上述步骤二中的相关描述，此处不再赘述。
步骤六、终端根据第二参数和第二参数对应的偏移量确定PUCCH时域资源。
示例性地，上述步骤六具体可以是：终端根据PRI域中获取第二参数的值，以及根据新增的子信息域或新增的PRI字段中获取第二参数的偏移量；进而终端根据第二参数的值，和第二参数的偏移量确定在步骤五种确定的PUCCH资源集合中确定相应的PUCCH时域资源。例如，终端获取的第二参数的值为0，第二参数的偏移量为j，上述步骤二中确定的PUCCH资源集合为支持32个PUCCH资源的第一个PUCCH资源集合，则终端确定用于发送反馈信息的PUCCH资源为第一个PUCCH资源集合中的第(0+j+1)个PUCCH资源。
在本申请实施例中的又一种PUCCH资源确定方式可以是：终端根据第一参数以及第一参数对应的偏移量、第二参数以及第二参数对应的偏移量确定PUCCH资源。具体来说，此种情况下，终端可以依次执行步骤一、步骤二和步骤六，此处不再赘述。
本申请实施例中，终端接收网络设备发送的指示信息，该指示信息用于指示时域偏移量，该时域偏移量用于终端确定PUCCH时域资源，应理解，对于任意一个终端而言，每个终端的时域偏移量均是专用的，独立配置的，互不影响的，而不是所有终端公用的，因此，每个终端根据时域偏移量、第一参数和第二参数确定PUCCH时域资源，可以使得每个终端的PUCCH时域资源在时域上是错开的，可以减少同一时刻终端传输的PUCCH数量，从而降低系统负载，提高系统性能。
为了进一步理解本申请实施例的技术方案，下面以四个终端UE#1、UE#2、UE#3和UE#4为例，结合具体的应用场景进行详细说明。需要说明的是，以下场景中的offset#0，offset#1，offset#2，offset#3分别表示UE#1、UE#2、UE#3、UE#4对应的偏移值PUCCH#1， PUCCH#2，PUCCH#3，PUCCH#4分别表示一个PUCCH资源集合中第一个至第四个PUCCH资源。
场景一、时域偏移量为第一参数对应的偏移量。
网络设备为UE#1、UE#2、UE#3和UE#4分别配置的的K1的偏移值分别为offset#0、offset#1，offset#2，offset#3。UE#1、UE#2、UE#3和UE#4接收同一多播传输的第二PDCCH。其中UE#1、UE#2、UE#3和UE#4均根据第二PDCCH上承载的PDSCH到HARQ反馈定时指示域确定PUCCH在第一个子时隙传输，UE#1根据K1偏移值为0，确定第一子时隙为UE#1PUCCH所在的子时隙；UE#2根据K1偏移值为1，确定第二个子时隙为UE#1PUCCH所在的子时隙；UE#3根据K1偏移值为2，确定第三个子时隙为UE#1PUCCH所在的子时隙；UE#4根据K1偏移值为3，确定第四个子时隙为UE#1PUCCH所在的子时隙。
UE#1、UE#2、UE#3和UE#4根据反馈信息负载大小确定对应的PUCCH资源集合为第一个PUCCH资源集合。UE#1、UE#2、UE#3和UE#4根据第一PDCCH上承载的PRI域和高层信令/参数配置确定PUCCH#1为UE#1传输PDCCH调度的PDSCH对应的反馈信息HARQ的PUCCH。由于没有第二参数对应的偏移量，UE#1、UE#2、UE#3和UE#4均根据第二参数对应的偏移量为offset#0将PUCCH#1为UE#1、UE#1、UE#2、UE#3和UE#4传输PDCCH调度的PDSCH对应的反馈信息HARQ的PUCCH。
在接收到网络设备发送的PDSCH之后，UE#1、UE#2、UE#3和UE#4分别在第一个子时隙上的PUCCH#1资源、第二个子时隙上的PUCCH#1资源、第三个子时隙上的PUCCH#1资源、第四个子时隙上的PUCCH#1资源上发送PDSCH对应的反馈信息。
在上述场景一中，接收同一多播传输的第二PDCCH的UE#1、UE#2、UE#3和UE#4发送的PDSCH对应的反馈信息在不同的子时隙中发送，使得PUCCH在时域上错开，减小了系统负载，提高了系统性能。
场景二、时域偏移量为第二参数对应的偏移量。
网络设备为UE#1、UE#2、UE#3和UE#4分别配置第二参数对应的偏移量分别为offset#0、offset#1，offset#2，offset#3。UE#1、UE#2、UE#3和UE#4接收用于调度多播传输的第一PDCCH。其中UE#1、UE#2、UE#3和UE#4均根据第一PDCCH上承载的PDSCH到HARQ反馈定时指示域确定PUCCH在第一个子时隙传输。UE#1、UE#2、UE#3和UE#4根据反馈信息负载大小确定对应的PUCCH资源集合为第一个PUCCH资源集合。UE#1、UE#2、UE#3和UE#4根据第一PDCCH上承载的PRI域和高层信令/参数配置确定PUCCH#1为UE#1传输PDCCH调度的PDSCH对应的反馈信息HARQ的PUCCH。UE#1根据第二参数对应的偏移量为offset#0将PUCCH#1确定为UE#1传输PDCCH调度的PDSCH对应的反馈信息HARQ的PUCCH；UE#2根据第二参数对应的偏移量offset#1和PRI域确定的PUCCH#1确定PUCCH#2为UE#2传输PDCCH调度的PDSCH对应的反馈信息HARQ的PUCCH；UE#3根据第二参数对应的偏移量offset#2和PRI域确定的PUCCH#2确定PUCCH#3为UE#3传输PDCCH调度的PDSCH对应的反馈信息HARQ的PUCCH；UE#4根据第二参数对应的偏移量offset#3和PRI域确定的PUCCH#3确定PUCCH#4为UE#4传输PDCCH调度的PDSCH对应的反馈信息HARQ的PUCCH。在接收到网络设备发送的PDSCH之后，UE#1、UE#2、UE#3和UE#4分别在第一个子时隙上的PUCCH#1 资源、PUCCH#2资源、PUCCH#3资源和PUCCH#4资源上发送PDSCH对应的反馈信息。
在上述场景二中，接收同一多播传输的第一PDCCH的UE#1、UE#2、UE#3和UE#4发送的PDSCH对应的反馈信息在同一个子时隙中不同的PUCCH资源上发送，使得PUCCH在时域上错开，减小了系统负载，提高了系统性能。
应理解，结合上述场景一和场景二，可以得到时域偏移量包括：第一参数对应的的偏移量，和，第二参数对应的偏移量的应用场景。
在一些可能的实施例中，时域偏移量可是由终端标识得到的，其具体运算方式可以是取模运算、取余运算等。
例如，在上述场景一中第一参数对应的偏移量是由UE ID取模得到的，如对UE ID进行模2运算得到相应终端的第一参数对应的偏移量，则UE#1和UE#3的第一参数对应的偏移量相同都为为offset#1；UE#2和UE#4的第一参数对应的偏移量为为offset#0，在此种情况下，UE#1和UE#3最终确定的发送PDSCH对应的反馈信息的子时隙是一样的，同样的，UE#2和UE#4最终确定的发送PDSCH对应的反馈信息的子时隙是一样的，从而可以将UE#1、UE#2、UE#3和UE#4部分终端的PDCCH对应的子时隙部分错开，减小了系统负载，提高了系统性能。
又如，在上述场景二中第二参数对应的偏移量是由UE ID取模得到的，如对UE ID进行模2运算得到相应终端的第二参数对应的偏移量，则UE#1和UE#3的第二参数对应的偏移量相同都为1；UE#2和UE#4的第二参数对应的偏移量为为offset#0，在此种情况下，UE#1和UE#3最终确定的发送PDSCH对应的反馈信息的PUCCH是一样的，同样，UE#2和UE#4最终确定的发送PDSCH对应的反馈信息的PUCCH是一样的，从而可以实现将UE#1、UE#2、UE#3和UE#4中部分终端的PUCCH在同一个子时隙中错开，减小了系统负载，提高了系统性能。
需要说明的是，上述的PUCCH#1、PUCCH#2、PUCCH#3和PUCCH#4有不同的频域或者码域(时域正交覆盖码、循环位移)配置。
