传输方法、终端设备及网络侧设备
相关申请的交叉引用
本公开主张在2020年9月22日在中国提交的中国专利申请号No.202010999105.8的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，具体涉及一种传输方法、终端设备及网络侧设备。
背景技术
在无线通信系统中，网络侧设备基于解调参考信号(Demodulation Reference Signal，DMRS)的信道估计的结果，对物理上行共享信道(Physical Uplink Shared Channel，PUSCH)进行解调。为了提高数据传输的可靠性，网络侧设备可以在物理下行控制信道(Physical Downlink Control Channel，PDCCH)中向终端侧设备发送特定格式的下行控制信息(Downlink Control Information，DCI)，该下行控制信息中包含用于确定被调度的上行数据所使用的DMRS天线端口号的指示信息。终端设备根据DCI中的指示信息确定DMRS天线端口，并采用该天线端口发送PUSCH。
在多传输接收点(Multi-Transmission Reception Point，Multi-TRP)的通信场景中，终端设备同时与多个TRP进行数据传输。如图1和图2所示，终端设备同时与TRP1和TRP2连接，终端设备基于接收到的DCI-0，向TRP1和TRP2发送多个PUSCH。为了提升多个TRP对PUSCH的接收性能，在对PUSCH进行重复传输时，PUSCH所采用的参数是分别基于不同的TRP的信道质量确定的。这样，当基于多个TRP的信道所确定的PUSCH的码本、流数等参数不同时，则PUSCH所采用的DMRS端口不同。
因此，如何通过尽可能少的字段来指示两个或两个以上的PUSCH的DMRS端口集合，以降低DCI开销，成为需要解决的问题。

步骤302、发送第一PUSCH和至少一个第二PUSCH；所述第一PUSCH采用所述天线端口指示字段指示的第一DMRS端口集合，所述第二PUSCH 采用的第二DMRS端口集合为所述第一DMRS端口集合的子集。
终端设备可以根据天线端口指示字段先确定第一DMRS端口集合，该第一DMRS端口集合对应第一PUSCH，并基于第一DMRS端口集合进一步确定第二DMRS端口集合，该第二DMRS端口集合为第一DMRS端口集合的子集，该第二DMRS端口集合对应至少一个第二PUSCH。
其中，第一DMRS端口集合的子集可以包括真子集和端口集合本身。当第二DMRS端口集合为第一DMRS端口集合的真子集时，第二PUSCH的秩小于第一PUSCH的秩；当第二DMRS端口集合为第一DMRS端口集合的集合本身时，第一PUSCH和第二PUSCH的秩相同，也就是说，第二DMRS端口集合与第一DMRS端口集合相同。
本公开具体实施例中，终端通过一个天线端口指示字段来确定多个PUSCH对应的DMRS端口集合，相对于相关技术中的天线端口指示字段和DMRS端口集合一一对应关系，能够减少DCI开销。
可选的，所述第一PUSCH和至少一个第二PUSCH为重复传输的PUSCH。
在重复传输的场景中，终端设备向多个TRP发送重复传输的第一PUSCH和至少一个第二PUSCH，能够提高PUSCH传输的可靠性。且基于DCI中的至少一个指示字段确定了多个PUSCH的DMRS端口集合，能够减少开销，提高指示的灵活性。
可选的，所述第二PUSCH的秩小于或等于所述第一PUSCH的秩。
在该实施方式中，第二PUSCH采用的第二DMRS端口集合为基于第一PUSCH采用的第一DMRS端口集合确定的子集，在第二DMRS端口集合为第一DMRS端口集合的真子集的情况下，第二PUSCH的秩小于第一PUSCH的秩；在第二DMRS端口集合为第一DMRS端口集合的集合本身的情况下，第二PUSCH的秩等于第一PUSCH的秩。
例如，第一PUSCH采用的第一DMRS端口集合为{0,1,2,3}，第二PUSCH采用的第二DMRS端口集合为基于集合{0,1,2,3}确定的子集：{0,1,2}、{0,1}、{1,2,3}、或{0,1,2,3}。
当第一PUSCH的秩和第二PUSCH的秩不同时，可以根据第一PUSCH的秩和第二PUSCH的秩中较大的秩确定采用的DMRS表格和DCI中天线端 口的bit(比特)数，并在DCI中指示较大秩的PUSCH所采用的DMRS端口，较小秩的PUSCH所对应的DMRS端口是DCI中指示的DMRS端口的一个子集。
这样，能够在不增加DCI大小或者增加DCI的较小bit数的情况下，指示多个PUSCH的DMRS端口集合，能够减少开销，提高资源利用率。
可选的，所述第二DMRS端口集合还可以依据如下信息中的至少一个确定：DMRS端口的时域位置、DMRS端口的频域位置、DMRS端口所属的CDM(Code Division Multiplexing，码分复用)组和DMRS端口的端口号。
在该实施方式中，可以基于DMRS端口的时域位置、DMRS端口的频域位置、DMRS端口所属的CDM组和DMRS端口的端口号中的一个或者多个确定第二DMRS端口集合。
例如，在相同时域位置的DMRS端口中，选择DMRS端口的端口号较小的集合作为第二DMRS端口集合；或者在相同时域位置的DMRS端口中，选择频域位置相同的DMRS端口作为第二DMRS端口集合。
依据上述信息确定第二DMRS端口集合，能够节约资源，提高DMRS的发送功率。
进一步地，所述第二DMRS端口集合依据如下规则中的至少一个确定：
第一规则、从所述第一DMRS端口集合中，选择位于不同的符号的DMRS端口。
在PUSCH重复传输的场景中，对DMRS所分配的时频资源位置是相同的，如果rank(秩)数大的PUSCH的DMRS占用的符号较多，而rank数少的PUSCH的DMRS只占用的符号较少，则会导致资源的浪费。因此，在此规则中，可以根据DMRS端口所占用的符号进行分类，选取位于不同符号的DMRS端口构成的子集作为第二DMRS端口集合，从而减少资源的浪费。
例如，终端设备发送的2个PUSCH的rank分别为rank＝4和rank＝2。其中，DCI指示第一DMRS端口集合A＝{0,2,4,6}用于rank＝4的PUSCH传输，rank＝2的PUSCH的第二DMRS端口集合从集合A的子集中确定。由于端口0,2位于时域第一个符号，端口4,6位于时域第二个符号，如果采用子集{0,2}作为第二DMRS端口集合则会仅仅占用1个符号，导致资源浪费，因此可以 采用子集{0,4}作为第二DMRS端口集合，子集{0,4}占用了2个符号，能减少资源的浪费，且能够在每个符号上提升DMRS的发送功率。
第二规则、从所述第一DMRS端口集合中，选择位于相同的频域RE(Resource Element，资源单元)的DMRS端口。
按照该规则确定第二DMRS端口集合，可以利用功率提升的方式提升DMRS的发送功率。
另外，还可以结合DMRS端口所在的时域位置和频域位置共同确定第二DMRS端口集合。例如，针对时域位置相同的DMRS端口，进一步根据DMRS所在的频域位置进行分类，并优先选用相同频域位置的DMRS端口构成的子集作为第二DMRS端口集合。
例如，终端设备发送的2个PUSCH的rank分别为rank＝4和rank＝2。其中，DCI指示第一DMRS端口集合A＝{0,1,2,3}用于rank＝4的PUSCH传输，rank＝2的PUSCH的第二DMRS端口集合从集合A的子集中确定。由于端口0,1,2,3位于时域的同一个符号，且端口0,1和2,3分别占用不同的频域资源，可以采用子集{0,1}或者子集{2,3}作为第二DMRS端口集合。选择位于相同频域位置的DMRS端口，能够提高DMRS的发送功率。
第三规则、从所述第一DMRS端口集合中，选择位于相同CDM组的DMRS端口。
按照该规则确定第二DMRS端口集合，可以利用功率提升的方式提升DMRS的发送功率。
另外，还可以针对时域位置相同的DMRS端口，进一步根据DMRS端口所在的CDM组进行分类，优先选取相同的CDM组中的DMRS端口构成子集作为第二DMRS端口集合。
例如，终端设备发送的2个PUSCH的rank分别为rank＝4和rank＝2。其中，DCI指示第一DMRS端口集合A＝{0,1,2,3}用于rank＝4的PUSCH传输，rank＝2的PUSCH的第二DMRS端口集合从集合A的子集中确定。由于端口0,1,2,3位于时域的同一个符号，且DMRS端口0,1属于CDM组0，DMRS端口2,3属于CDM组1，因此，可以采用子集{0,1}或{2,3}作为第二DMRS端口集合。选择位于相同CDM组的DMRS端口，能够提高DMRS的发送功 率。
第四规则、从所述第一DMRS端口集合中，按端口号从小到大的顺序选择DMRS端口。
在本规则中，可以将第一DMRS端口集合中的DMRS端口按照从小到大的顺序进行排序，并优先选择端口号较小的DMRS端口的集合作为第二DMRS端口集合。另外，还可以在相同时域、相同频域或者相同CDM组的DMRS端口中，进一步选择端口号较小的DMRS端口集合作为第二DMRS端口集合。
在具体实施时，可以选择上述任一规则，或者将上述规则结合确定。
可选的，所述第一规则的优先级最高，所述第四规则的优先级最低，第二规则和第三规则的优先级介于所述第一规则的优先级和第四规则的优先级之间。
在具体实施时，可以按照上述规则的优先级顺序确定第二DMRS端口集合。另外，还可以结合上述多个规则，以及上述规则的优先级顺序，按照以下步骤确定第二DMRS端口集合：
步骤一、根据DMRS端口所占用的时域位置进行分类，优先选取不同时域位置的DMRS端口构成子集。在步骤一条件不存在的情况下，还可以根据步骤二或步骤三确定。
步骤二、针对时域位置相同的DMRS端口，进一步根据DMRS端口所在的CDM组(或所在的频域资源)进行分类，优先选取位于相同的CDM组(或相同频域资源)的DMRS端口构成子集。
步骤三、对于相同时域位置，位于相同CDM组内(或相同频域资源)的DMRS端口，进一步根据DMRS端口号大小进行分类，优先选取端口号较小的DMRS端口。
基于上述步骤可以选取N个DMRS端口，其中，N为rank数较小的PUSCH所对应的rank。
为了便于理解上述方案，以下进行举例说明。
例如，2个PUSCH的rank分别为rank＝4和rank＝2，其中，DCI指示rank＝4对应的PUSCH的端口集合A＝{0,2,4,6}。rank＝2对应的PUSCH的端口集合 的确定过程可以按照以下步骤的优先级顺序确定：
第一步，UE根据时域位置选取位于不同时域位置的两个DMRS端口，即分别选取{0,2}中的1个和{4,6}中的一个。在第一步的条件不成立的情况下，可以获取时域位置相同，且频域资源相同的DMRS端口集合，即执行第二步。
第二步，由于时域位置相同的端口号0和2的频域位置不同，时域位置相同的4和6的频域位置不同，第二步无法再缩小集合；在第二步的条件不成立的情况下，还可以执行第三步。
第三步，针对相同CDM组内的DMRS端口，根据端口号大小分类，按照从小到大的原则选择端口集合，确定子集＝{0,4}。
按照上述优先级顺序确定第二DMRS端口集合，能够利用有限的DCI的空间大小，灵活地确定多种PUSCH的DMRS端口集合，能够节约DCI的开销，且能够提高DMRS的发送功率。
此外，终端设备还可以依照如下规则从第一DMRS端口集合中确定第二DMRS端口集合。
规则一、根据端口号大小选择
例如，终端设备向2个TRP发送重复传输的第一PUSCH和第二PUSCH。若DCI指示第一PUSCH采用的第一DMRS端口集合为{0,1,2,3}，则第二PUSCH采用的第二DMRS端口集合可以从集合{0,1,2,3}中选择端口号最小的子集，即{0,1}，或者可以从集合{0,1,2,3}中选择端口号最大的子集，即{2,3}。
在具体实施时，可以将第一DMRS端口集合按照端口号的大小进行排序后，然后选取前K个构成子集，K为秩数较小的PUSCH所对应的秩。例如，终端设备发送的2个PUSCH的秩分别为4和2，其中，DCI指示秩为4的PUSCH的DMRS端口集合为{0,1,2,3}，终端设备选择端口号最小的子集，确定秩为2的PUSCH的DMRS端口集合为{0,1}。
规则二、随机选择
例如，终端设备向2个TRP发送重复传输的第一PUSCH和第二PUSCH。若DCI指示第一PUSCH采用的第一DMRS端口集合为{0,2,4,6}，则第二PUSCH采用的第二DMRS端口集合可以从集合{0,2,4,6}中随机选择，当第二PUSCH的秩为3时，得到的端口集合可以为{0,2,4}，{0,2,6}，{2,4,6}或{0,4,6}。
对于DCI指示了多个天线端口指示字段，且该字段的数量少于PUSCH的数量的情况，以终端设备向4个TRP发送重复传输的PUSCH的情况为例，第二DMRS端口集合还可以采用以下规则确定：
规则三、基于天线端口指示字段指示的两个端口集合中的至少一个确定
例如，终端设备发送的两个第一PUSCH采用的第一端口集合为由DCI指示的两个端口集合{0,1,2,3}和{0,2,4,6}，两个第二PUSCH采用的第二DMRS端口集合则可以基于{0,1,2,3}和{0,2,4,6}中的至少一个集合获取两个子集。则第二DMRS端口集合可以有以下几种确定方式：
A、分别从{0,1,2,3}和{0,2,4,6}中选取子集，确定第二DMRS端口集合为{0,1,2}和{0,2,4}，或，{0,2,3}和{0,4,6}，或，{1,2,3}和{2,4,6}；
B、从{0,1,2,3}中选取子集，确定第二DMRS端口集合分别为{0,1,2}和{0,2,3}，或，{0,2,3}和{1,2,3}；
C、从{0,2,4,6}中选取子集，确定第二DMRS端口集合分别为{0,2,4}和{0,4,6}，或，{0,4,6}和{2,4,6}。
规则四、基于天线端口指示字段指示的三个端口集合中的一个确定
例如，终端设备发送了四个PUSCH，其中一个PUSCH采用的DMRS端口集合为由DCI指示的{0,1,2,3}，一个PUSCH采用的第二DMRS端口集合则可以基于{0,1,2,3}获取子集确定。其余的两个PUSCH的DMRS端口集合也可以由DCI直接指示确定。
在这种规则下，通过增加DCI中DMRS端口指示的bit数，分别指示了多个PUSCH的DMRS端口。虽然DCI中增加了bit数，由于天线指示字段的数量小于PUSCH的数量，能够节约DCI的大小，减少开销。
上述几种规则仅仅是举例，在实际应用时可以不限于此。由于DCI中指示了一个天线指示字段，终端设备能够根据该指示字段指示的DMRS端口集合确定至少两个DMRS端口集合，这样，在调度PUSCH进行传输时，能够利用有限的DCI大小，指示多个PUSCH的DMRS端口集合，能够减少DCI的开销。
参见图4，图4是本公开实施例提供的传输方法的流程图，该传输方法应用于网络侧设备，如图4所示，包括以下步骤：
步骤401、发送下行控制信息DCI，所述DCI包括天线端口指示字段，所述天线端口指示字段用于指示DMRS端口集合。
步骤402、在所述天线端口指示字段指示的第一DMRS端口集合接收第一PUSCH。
步骤403、在第二DMRS端口集合接收至少一个第二PUSCH，所述第二DMRS端口集合为所述第一DMRS端口集合的子集。
本公开实施例与上述实施例是分别从终端设备侧和网络设备侧实现的传输方法，因此，本公开实施例中网络侧设备对应的传输方法的实现过程和有益效果可以参见上述实施例中的描述，此处不再赘述。
其中，DCI中可以包含至少一个天线端口指示字段，指示了第一PUSCH对应的第一DMRS端口集合，终端设备还可以依据第一DMRS端口集合确定第二PUSCH对应的第二DMRS端口集合，其中，第二DMRS端口集合为第一DMRS端口集合的子集。这样，终端通过一个天线端口指示字段来确定多个PUSCH对应的DMRS端口集合，相对于相关技术中的天线端口指示字段和DMRS端口集合一一对应关系，能够减少DCI开销。
可选的，所述第一PUSCH和至少一个第二PUSCH为重复传输的PUSCH。
该实施方式中，能够减少部分TRP在传输环境较差时导致信息时延，能够提高PUSCH传输的可靠性。
可选的，所述第二PUSCH的秩小于或等于所述第一PUSCH的秩。
在该实施方式中，第二PUSCH采用的第二DMRS端口集合为基于第一PUSCH采用的第一DMRS端口集合确定的子集，第二DMRS端口集合为第一DMRS端口集合的真子集或集合本身。
当第一PUSCH的秩和第二PUSCH的秩不同时，可以根据第一PUSCH的秩和第二PUSCH的秩中较大的秩确定采用的DMRS表格和DCI中天线端口的bit(比特)数，并在DCI中指示较大秩的PUSCH所采用的DMRS端口，较小秩的PUSCH所对应的DMRS端口是DCI中指示的DMRS端口的一个子集。
这样，能够在不增加DCI大小或者增加DCI的bit数较小的情况下，指示多个PUSCH的DMRS端口集合，能够减少开销，提高资源利用率。
可选的，所述第二DMRS端口集合还可以依据如下信息中的至少一个确定：DMRS端口的时域位置、DMRS端口的频域位置、DMRS端口所属的CDM组和DMRS端口的端口号。
在该实施方式中，可以基于DMRS端口的时域位置、DMRS端口的频域位置、DMRS端口所属的CDM组和DMRS端口的端口号中的一个或者多个确定第二DMRS端口集合。
例如，在相同时域位置的DMRS端口中，选择DMRS端口的端口号较小的集合作为第二DMRS端口集合；或者在相同时域位置的DMRS端口中，选择频域位置相同的DMRS端口作为第二DMRS端口集合。
进一步地，所述第二DMRS端口集合依据如下规则中的至少一个确定：
第一规则、从所述第一DMRS端口集合中，选择位于不同的符号的DMRS端口。
在此规则中，可以根据DMRS端口所占用的符号进行分类，选取位于不同符号的DMRS端口构成的子集作为第二DMRS端口集合，从而减少资源的浪费。
第二规则、从所述第一DMRS端口集合中，选择位于相同的频域RE的DMRS端口。
按照该规则确定第二DMRS端口集合，可以利用功率提升的方式提升DMRS的发送功率。
另外，还可以结合DMRS端口所在的时域位置和频域位置共同确定第二DMRS端口集合。例如，针对时域位置相同的DMRS端口，进一步根据DMRS所在的频域位置进行分类，并优先选用相同频域位置的DMRS端口构成的子集作为第二DMRS端口集合，能够提高DMRS的发送功率。
第三规则、从所述第一DMRS端口集合中，选择位于相同CDM组的DMRS端口。
按照该规则确定第二DMRS端口集合，可以利用功率提升的方式提升DMRS的发送功率。
另外，还可以针对时域位置相同的DMRS端口，进一步根据DMRS端口所在的CDM组进行分类，优先选取相同的CDM组中的DMRS端口构成子 集作为第二DMRS端口集合，能够提高DMRS的发送功率。
第四规则、从所述第一DMRS端口集合中，按端口号从小到大的顺序选择DMRS端口。
在本规则中，可以将第一DMRS端口集合中的DMRS端口按照从小到大的顺序进行排序，并优先选择端口号较小的DMRS端口的集合作为第二DMRS端口集合。另外，还可以在相同时域、相同频域或者相同CDM组的DMRS端口中，进一步选择端口号较小的DMRS端口集合作为第二DMRS端口集合。
在具体实施时，可以选择上述任一规则，或者将上述规则结合确定。
可选的，所述第一规则的优先级最高，所述第四规则的优先级最低，第二规则和第三规则的优先级介于所述第一规则的优先级和第四规则的优先级之间。
在具体实施时，可以按照上述规则的优先级顺序确定第二DMRS端口集合。另外，还可以结合上述多个规则，以及上述规则的优先级顺序，按照以下步骤确定第二DMRS端口集合：
步骤一、根据DMRS端口所占用的时域位置进行分类，优先选取不同时域位置的DMRS端口构成子集。在步骤一的条件不成立的情况下，则可以根据步骤二或步骤三确定。
步骤二、针对时域位置相同的DMRS端口，进一步根据DMRS端口所在的CDM组(或所在的频域资源)进行分类，优先选取位于相同的CDM组(或相同频域资源)的DMRS端口构成子集。
步骤三，对于相同时域位置，位于相同CDM组内(或相同频域资源)的DMRS端口，进一步根据DMRS端口号大小进行分类，优先选取端口号较小的DMRS端口。
基于上述步骤可以选取N个DMRS端口，其中，N为rank数较小的PUSCH所对应的rank。
另外，此外，终端设备还可以根据以下规则确定第二DMRS端口集合，如，根据端口号大小选择、随机选择、基于多个端口集合中的一个或者多个选择。具体可以参见上述实施例的描述，以及能够达到相同的有益效果，此 处不再赘述。

例如，在第一PUSCH和第二PUSCH的秩不同的情况下，网络侧设备向终端设备发送包括2个天线端口指示字段的DCI，分别用于指示第一PUSCH对应的第一DMRS端口集合和第二PUSCH对应的第二DMRS端口集合。终端设备根据DCI指示的两个端口集合，采用该两个端口集合发送第一PUSCH和第二PUSCH。
通过DCI指示多个DMRS端口集合，能够针对性地采用DMRS端口集合发送PUSCH，能够提高数据传输的可靠性。
