Description

通信方法和通信装置

背景技术
在第五代(the fifth generation，5G)通信系统中，同一个终端设备可以在同一个时隙(slot)中发送两个物理上行控制信道(physical uplink control channel，PUCCH)，且这两个PUCCH是时分复用(time diversity multiplexing，TDM)的。PUCCH可以用于承载上行控制信息(uplink control information，UCI)，而UCI可以包含混合自动重传请求应答(hybrid automatic repeat request-acknowledgment，HARQ-ACK)、信道状态信息(channel state information，CSI)。因此，同一个终端设备可以在同一个时隙中发送两个TDM的HARQ-ACK信息。
在这种情况下，在接收了网络设备发送的下行调度(assignment)信令后，终端设备接收下行数据信息，进而确定承载该下行数据信息的HARQ-ACK的PUCCH资源，并确定是否有多个下行调度信令对应的HARQ-ACK都在该PUCCH资源上进行反馈。
在目前的调度机制中，终端设备无法通过调度信令判断哪些HARQ-ACK需要进行合并反馈，这成为一个亟需解决的问题。

图4是本申请实施例的通信装置的一例的示意性框图。
图5是本申请实施例的通信装置的另一例的示意性框图。
具体实施方式
在5G通信系统中，终端设备根据下行调度信令中的下行调度指示(downlink assignment indicator，DAI)确定所需反馈的肯定应答(acknowledgement，ACK)或否定应答(negative acknowledgement，NACK)的比特数，并根据该比特数进一步确定进行反馈需要使用的PUCCH资源所属的PUCCH资源集，最后根据应答资源指示(ACK or NACK resource indicator，ARI)在该资源集中确定反馈该应答所使用的PUCCH资源。
由于每个PUCCH对应的下行调度信令中的DAI都是独立计数的，这种通过DAI确定合并的方式不适用于有两个PUCCH同时反馈的情况。例如，当收到两个DAI＝1的下行调度信令后又收到DAI＝2的下行调度信令时，终端设备无法确定该DAI＝2的下行调度对应的HARQ-ACK应该与哪个DAI＝1的下行调度信令对应的HARQ-ACK合并进行反馈。
下面将结合附图，对本申请中的技术方案进行描述。

图2示出了网络设备和终端设备之间的通信过程，即，通信方法200。在下面的描述中，该网络设备向该终端设备发送信息不限于该网络设备通过单播方式直接向该终端设备发送该信息的情况，还包含该网络设备通过广播、多播、组播等方式发送该信息，而该终端设备接收到该信息的情况，此外，该网络设备发送的信息还可以通过其他设备被转发给该终端设备。
在S210，该网络设备确定两个下行调度信令。这两个下行调度信令指示两个物理上行控制信道(PUCCH)资源，且这两个PUCCH资源在同一时间单元上。时间单元可以是时隙(slot)，一个时隙在时间上包含N(N为正整数，例如N＝14)个OFDM符号。这两个下行调度信令中的下行调度指示(DAI)是不同的。DAI用于指示下行调度信令的索引，如果N个下行调度信令在同一PUCCH资源上反馈应答信息，则这N个下行调度信令的DAI是逐一递增的。该网络设备确定这两个下行调度信令的过程可以是单独进行的。
在S220，终端设备从网络设备接收这两个下行调度信令。该终端设备接收这两个下行调度信令的过程可以是单独进行的。在本实施例中以网络设备确定并向终端设备发送两个下行调度信息为例进行描述，但本申请不限于此，当网络设备确定并向终端设备发送的下行调度信令的数量多于两个时，其他下行调度信令可也适用于本实施例所描述的方法。
在S230，该终端设备根据每个下行调度信令的第一信息确定承载每个下行调度信令所调度的下行数据的应答信息的PUCCH资源。
这里，该终端设备可以根据每个下行调度信令的第一信息确定承载每个下行调度信令所调度的下行数据的应答信息的PUCCH资源是否为同一PUCCH资源。
作为示例，在每个下行调度信令的第一信息属于同一集合的情况下，承载每个下行调度信令所调度的下行数据的应答信息的PUCCH资源为这两个下行调度信令之中的最后一个接收到的下行调度信令所指示的PUCCH资源，例如，这两个下行调度信令为下行调度信令#A和下行调度信令#B，下行调度信令#A所指示的PUCCH资源为PUCCH资源#a，下行调度信令#B所指示的PUCCH资源为PUCCH资源#b，且下行调度信令#B为这两个下行调度信令之中最后一个被接收到的下行调度信令，则下行调度信令#A所调度的下行数据的应答信息和下行调度信令#B所调度的下行数据的应答信息均被承载在PUCCH资源#b上。此外，还可以根据其他规则来判定这两个下行调度信令之中的哪个下行调度信令用于承载应答信息。这里，未用于承载这两个下行调度信令所调度的下行数据的应答信息的PUCCH资源可以用于承载其他下行调度信令所调度的下行数据的应答信息，例如，在下行调度信令#A所调度的下行数据的应答信息和下行调度信令#B所调度的下行数据的应答信息均被承载在PUCCH资源#b上的情况下，PUCCH资源#a可以用于承载除了下行调度信令#A和下行调度信令#B以外的下行调度信令所调度的下行数据的应答信息。
作为另一示例，在每个下行调度信令的第一信息属于不同集合的情况下，承载每个下行调度信令所调度的下行数据的应答信息的PUCCH资源为该下行调度信令所指示的PUCCH资源，例如，这两个下行调度信令为下行调度信令#A和下行调度信令#B，下行调度信令#A所指示的PUCCH资源为PUCCH资源#a，下行调度信令#B所指示的PUCCH资源为PUCCH资源#b，则下行调度信令#A所调度的下行数据的应答信息被承载在PUCCH资源#a上，下行调度信令#B所调度的下行数据的应答信息被承载在PUCCH资源#b上。
在S240，该终端设备在确定的PUCCH资源上向该网络设备发送每个下行调度信令所调度的下行数据的应答信息。
根据上述通信方法，在同一时间单元上的多个PUCCH资源均可用于反馈应答信息的情况下，该终端设备和该网络设备能够获知下行调度信令所调度的下行数据的应答信息被承载在这些PUCCH资源之中的哪个PUCCH资源上，从而支持在同一时间单元上的多个PUCCH资源上反馈应答信息。
在本实施例中，该终端设备可以从该网络设备接收这两个下行调度信息所调度的下行数据，还可以确定该下行数据的应答信息以及确定用于反馈应答信息的UCI信息。这些处理可以按照现有技术中的任意方式进行，在此不做赘述。
可选地，该第一信息为这两个下行调度信令中的应答资源指示(ARI)。ARI用于指示该网络设备为该终端设备配置的PUCCH资源集(resource set)中的PUCCH资源，该PUCCH资源至少用于反馈该ARI对应的下行调度信令所调度的下行数据的应答信息。在这种情况下，第一信息属于不同集合的下行调度信令所指示的PUCCH资源可以是时分复用的。作为示例，第一信息的每个集合中可以包含不同类型的ARI索引，不同的集合中所包含的ARI索引的类型数可以是相同的，也可以是不同的。例如，当ARI由2比特指示时，在不同的集合中所包含的ARI索引的类型数相同的情况下， 集合#A包括索引为0和1的ARI，集合#B包括索引为2和3的ARI，或者，集合#A包括索引为0和2的ARI，集合#B包括索引为1和3的ARI，又或者，集合#A包括索引为0和3的ARI，集合#B包括索引为1和2的ARI；在不同的集合中所包含的ARI索引的类型数不同的情况下，集合#A包括索引为0、1和2的ARI，集合#B中包含索引为3的ARI，或者，集合#A包括索引为0、1和3的ARI，集合#B中包含索引为2的ARI，或者，集合#A包括索引为0、2和3的ARI，集合#B中包含索引为1的ARI，或者，集合#A包括索引为1、2和3的ARI，集合#B中包含索引为0的ARI。
通过这种方式，在支持在同一时间单元上的多个PUCCH资源上反馈应答信息的同时，可以减少不同的终端设备的下行调度信令的阻塞概率，且降低终端设备的盲检复杂度。
可选地，该第一信息为这两个下行调度信令所占用的控制资源集(control-resource set，CORESET)或搜索空间(search space)或混合自动重传请求(HARQ)进程号。HARQ进程号用于区分不同的HARQ进程，在一段时间内，一个HARQ进程用于完成一个数据的HARQ重传或HARQ合并等过程。CORESET用于发送控制信道的物理资源集合。搜索空间是候选控制信道集合。在这种情况下，在每个PUCCH资源集内，至少可以存在两个PUCCH资源是时分复用的，且至少可以存在一个PUCCH资源与属于其他PUCCH资源集的PUCCH资源是时分复用的，该PUCCH资源集包括至少两个PUCCH资源。作为示例，第一信息的每个集合中可以包含一定数量的CORESET/搜索空间/HARQ进程号，不同的集合中所包含的CORESET/搜索空间/HARQ进程号的数量可以是相同的，也可以是不同的。例如，当终端设备总共使用2N(N为正整数)个CORESET时，在不同的集合中所包含的CORESET的数量相同的情况下，集合#A包括这2N个CORESET之中的N个CORESET，集合#B中包括这2N个CORESET之中的另外N个CORESET；在不同的集合中所包含的CORESET的数量不同的情况下，集合#A包括这2N个CORESET之中的n个CORESET，集合#B中包括这2N个CORESET之中的m个CORESET，m和n之和为2N，且m不等于n。
通过这种方式，在支持在同一时间单元上的多个PUCCH资源上反馈应答信息的同时，可以降低终端设备的盲检复杂度，且降低ARI的调度限制。
可选地，该第一信息为这两个下行调度信令的下行控制信息(DCI)格式或加扰信息。DCI具有多种格式，不同格式的DCI包含不同的载荷或内容，其功能也不相同，例如，DCI format 0用于调度上行数据，DCI format 1用于调度下行数据。加扰信息用于终端设备判断接收到的DCI的目标终端设备或DCI format等。在这种情况下，在每个PUCCH资源集内，至少可以存在两个PUCCH资源是时分复用的，且至少可以存在一个PUCCH资源与属于其他PUCCH资源集的PUCCH资源是时分复用的，该PUCCH资源集包括至少两个PUCCH资源。作为示例，第一信息的每个集合中可以包含不同类型的DCI格式或加扰信息，不同的集合中所包含的DCI格式或加扰信息的类型数可以是相同的，也可以是不同的。例如，集合#A包括DCI format 1_0，集合#B包括DCI format 1_1，或者，集合#A包括DCI format 1_0和DCI format 1_1，集合#B包括DCI format 1_2。又例如，集合#A包括C-RNTI，集合#B包括除了C-RNTI以外的其他扰码。
通过这种方式，在支持在同一时间单元上的多个PUCCH资源上反馈应答信息的同时，可以降低终端设备的盲检复杂度，且降低ARI的调度限制。
可选地，该第一信息为这两个下行调度信令所指示的PUCCH资源。在这种情况下，所指示的PUCCH资源重叠的下行调度信令的第一信息可以属于同一集合，所指示的PUCCH资源不重叠的下行调度信令的第一信息可以属于不同集合，这里，两个PUCCH资源重叠是指这两个PUCCH资源在时域上所占用的OFDM符号之中至少存在一个相同的OFDM符号。
在现有技术中，同一时间单元上仅存在两个PUCCH资源，因此在上述的各种方式中，仅以第一信息的集合的数量为两个作为示例进行描述。然而，本实施例所描述的通信方法不限于仅支持两个第一信息的集合。例如，如果同一时间单元上存在三个能够进行应答信息反馈的PUCCH资源，可以将第一信息的集合的数量增加至三个，以此类推，即，增加第一信息的集合的数量可以支持更多的位于同一时间单元的PUCCH资源用于反馈应答信息。
可选地，通信方法200还包括S250。
作为示例，在S250，该终端设备根据每个下行调度信令的第一信息确定用于发送每个下行调度信令所调度的下行数据的应答信息的PUCCH资源上所承载的上行控制信息(UCI)的载荷量(payload size)。这里，在每个下行调度信令所调度的下行数据的应答信息分别在不同的PUCCH资源上被发送时，可以确定每个PUCCH资源上所承载的UCI的载荷量，在每个下行调度信令所调度的下行数据的应答信息在同一PUCCH资源上被发送时，可以确定这一个PUCCH资源上所承载的UCI的载荷量。上述处理可以在该终端设备被配置为类型二HARQ应答码本(Type-2 HARQ-ACK codebook)(该码本为动态码本)的情况下进行。可以根据某个PUCCH资源上所承载的应答信息的数量来确定每个应答信息所占据的比特数，例如，当PUCCH资源#a上仅承载应答信息#X时，可以用1比特(例如，0或1)来表示应答信息#X，而当PUCCH资源#a上同时承载应答信息#X和应答信息#Y时，需要分别用2比特(例如，00、01、10或11)来表示应答信息#X和应答信息#Y。之后，根据该PUCCH资源上所承载的应答信息所占据的比特数之和确定该PUCCH资源上所承载的UCI的载荷量。
作为另一示例，在S250，该终端设备根据类型一HARQ应答码本(Type-1 HARQ-ACK codebook)(该码本为半静态码本)确定用于发送每个下行调度信令所调度的下行数据的应答信息的PUCCH资源上所承载的UCI的载荷量。终端设备被配置为类型一HARQ应答后，终端设备在确定的时隙或PUCCH资源上反馈的HARQ-ACK的载荷量不随基站调度的下行数据的数量变化而变化。这里，这两个PUCCH所承载的UCI的载荷量相同，均为类型一HARQ应答码本所规定的UCI的载荷量。作为示例，当PUCCH所承载的应答信息所占据的总比特数小于该PUCCH所承载的UCI的载荷量时，对剩余的比特进行补零。
可选地，在S230，该终端设备根据协议预定义的信息或高层信令半静态配置的信息确定第一信息所属的集合，或者，该终端设备根据下行调度指令中的第一信息所属的集合的指示符确定第一信息所属的集合，第一信息所属的集合的指示符是由下行调度信令中的N(N为正整数)比特字段指示的。
虽然图3中示出了各个处理的先后顺序，但图中所示的先后顺序并不代表这些处理在时间上的先后顺序，这些处理可以按照任意的时间上的顺序进行，也可以同时进行。甚至于，某个处理的一部分可以在另一个处理之前进行，另外一部分可以在该另一个处理之后进行，例如，S210中确定第一个下行调度信令的处理、S220中接收该第一个下行调度信令的处理、S210中确定第二个下行调度信令的处理、S220中接收该第二个下行调度信令的处理在时间上可以按照上面所描述的顺序进行。
下面，结合图3，针对终端设备从网络设备接收每个下行调度信令及反馈该下行调度信令所调度的下行数据的应答信息的处理，对通信方法200进行扩展描述，应注意的是，下面的描述仅仅是示例性的。以终端设备依次从网络设备接收下行调度信令#A、下行调度信令#B和下行调度信令#C，且该终端设备预知PUCCH资源的第一信息所属的集合的相关信息为例。
首先，该网络设备确定并发送下行调度信令#A，下行调度信令#A所指示的PUCCH资源为PUCCH资源#a，且下行调度信令#A中的DAI为1。在确定下行调度信令#A的过程中，该网络设备会决定下行调度信令#A的第一信息。
该终端设备在时间单元n接收下行调度信令#A，按照下行调度信令#A中的信息，该下行调度信令对应的应答信息将在时间单元n+3的第二个PUCCH上进行反馈。
之后，该网络设备确定并发送下行调度信令#B，下行调度信令#B所指示的PUCCH资源为PUCCH资源#b，且下行调度信令#B中的DAI为1，PUCCH资源#a和PUCCH资源#b在同一时间单元上。在确定下行调度信令#B的过程中，该网络设备会决定下行调度信令#B的第一信息。虽然PUCCH资源#a和PUCCH资源#b在同一时间单元上，但这两个PUCCH资源中的DAI是相同的，而DAI相同说明这两个PUCCH资源属于两个不同的PUCCH资源集，因此，该网络设备在决定下行调度信令#B的第一信息时无需考虑下行调度信令#A。
该终端设备在时间单元n+1接收下行调度信令#B，按照下行调度信令#B中的信息，该下行调度信令对应的应答信息将在时间单元n+3的第一个PUCCH上进行反馈。虽然PUCCH资源#a和PUCCH资源#b在同一时间单元上，但下行调度信令#A和下行调度信令#B中的DAI是相同的，因此该终端设备无需判断这两个下行调度信令的第一信息是否属于同一集合。当然，该终端设备也可以无论如何都判断这两个下行调度信令的第一信息是否属于同一集合，然后再判断这两个下行调度信令中的DAI是否相同。
然后，该网络设备确定并发送下行调度信令#C，下行调度信令#C所指示的PUCCH资源为PUCCH资源#c，且下行调度信令#C中的DAI为2，PUCCH资源#a、PUCCH资源#b和PUCCH资源#c在同一时间单元上。在确定下行调度信令#C的过程中，该网络设备会决定下行调度信令#C的第一信息。下面以该网络设备将下行调度信令#C的第一信息设置为使得该终端设备能够判断出下行调度信令#C的第一信息与下行调度信令#A的第一信息属于同一集合，下行调度信令#B的第一信息属于另一集合为例。
该终端设备在时间单元n+2接收下行调度信令#C，按照下行调度信令#C中的信息，该下行调度信令对应的应答信息将在时间单元n+3的第二个PUCCH上进行反馈。由于PUCCH资源#a、PUCCH资源#b和PUCCH资源#c在同一时间单元上，且下行调 度信令#C中的DAI与下行调度信令#A中的DAI、下行调度信令#B的中DAI分别都是不同的，因此该终端设备需要分别判断下行调度信令#C的第一信息与下行调度信令#A的第一信息、下行调度信令#B的第一信息是否属于同一集合。根据该网络设备所设置的第一信息，该终端设备确定下行调度信令#C的第一信息与下行调度信令#A的第一信息属于同一集合，下行调度信令#B的第一信息属于另一集合。
因而，在时间单元n+3，该终端设备会在下行调度信令#B所指示的PUCCH资源#b上向该网络设备发送下行调度信令#B对应的应答信息，而该网络设备会在PUCCH资源#b上接收该应答信息；该终端设备会在下行调度信令#C所指示的PUCCH资源#c上向该网络设备发送下行调度信令#A对应的应答信息和下行调度信令#C对应的应答信息，而该网络设备会在PUCCH资源#c上接收这两个应答信息，即，下行调度信令#A所指示的PUCCH资源#a将不再用于传输下行调度信令#A对应的应答信息。根据前述方法，图4为本申请实施例提供的通信装置10的示意图，如图4所示，该装置10可以为终端设备，也可以为芯片或电路，比如可设置于终端设备的芯片或电路。
