为了传输数据或者信令，标准中把物理信道分成物理下行控制信道(Physical downlink control channel，PDCCH)，物理上行控制信道(Physical uplink control channel，PUCCH)，物理下行共享信道(Physical downlink shared channel，PDSCH)，物理上行共享信道(Physical uplink shared channel，PUSCH)。其中，PDCCH主要用于传输物理下行控制信令(Downlink Control Information，DCI)，而PUCCH主要用于传输上行控制信息，比如信道状态信息(Channel State Information，CSI)，混合自动重复传输(Hybrid automatic repeat request，HARQ)，调度请求(Scheduling Request)等，而PDSCH主要用于传输下行数据，PUSCH主要用于传输上行数据和CSI等信息。其中，CSI包括终端反馈的下行链路的信道状态信息和基站指示终端的上行链路的信道状态信息。其中，下行链路的信道状态信息包括但不限于以下信息中的至少之一：信道状态信息-参考信号资源指示(CSI-RS Resource Indicator，CRI)、同步信号块资源指示(Synchronization Signals Block Resource Indicator，SSBRI)、信道质量指示(Channel Quality Indicator，CQI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)、层指示(Layer Indicator，LI)、秩指示(Rank Indicator，RI)；上行链路的信道状态信息包括但不限于以下信息中的至少之一：上行探测信号资源指示(SRS resource Indicator，SRI)、传输预编码矩阵指示(Transmitted Precoding Matrix Indicator，TPMI)，传输秩指示(Transmitted Rank Indicator，TRI)，调制和编码方案(Modulation and coding scheme，MCS)，另外TPMI和TRI可能联合编码，用下行控制信令的预编码信息和层数域(即Precoding information and number  of layers)指示，空间滤波参数，空间相关参数，波束参数。空间滤波参数，空间相关参数，波束参数也可以通过SRI指示，或者通过准共位置(quasi co-located，QCL)参数确定。上行链路的信道状态信息也可以称作上行信道的参数。在下行控制信息中的上行探测信号资源指示域中包括一个用于指示SRS resource set中的SRS resource index(或者写作indicator)的上行探测信号资源指示，主要用于基于码本的上行传输，或者包括一组用于指示SRS resource set中的SRS resource index(或者写作indicator)的上行探测信号资源指示，主要用于基于非码本的上行传输，物理随机接入信道(Physical Random Access Channel，PRACH)是用于传输上行随机接入信息的信道。其中，物理上行信道包括如下至少之一：PUSCH；PUCCH，PRACH，而物理下行信道包括如下至少之一：PDSCH；PDCCH，本申请中的M个物理上行信道，可以是M个用于传输物理上行数据的物理上行信道资源，或者一个物理上行信道资源在不同传输时间，或者不同传输载波，不同传输子带上的一次传输，比如M个PUSCH，包括M个在不同上行传输单元上传输上行数据的PUSCH信道资源，或者物理上行数据在一个PUSCH的资源在不同时间上的M次传输，同理，本申请中的M个物理下行信道，可以是M个物理下行信道资源，或者一个物理下行信道资源在不同传输时间，或者不同传输载波，不同传输子带上的一次传输，比如M个PDCCH，可以包括M个PDCCH信道，或者一个PDCCH信道在不同的时间或者不同的频域传输了M次，其中，PDCCH携带了控制信道信息DCI。其中，所述的M个物理上行信道传输的上行数据也可以称为传输信息，所述传输信息可以是信道编码前的信息，或者传输块，或者是上行控制信息中的一个编码块或者多个编码块对应的一个大的编码块。本申请中所述的M个物理上行信道的信道状态信息，即是上行链路的信道状态信息，这是因为PUSCH、PUCCH等都是上行链路。本申请中的传输可以是发送，也可以是接收。
为了提高数据或者信令传输的可靠性，一种方式是重复(即repetition)的传输。M个数据(比如，PDSCH或PUSCH)传输是repetition的，是指所述M个数据携带了完全相同的信息，比如M个数据来自相同传输块(Transport Block，TB)，只是对应的信道编码后的冗余版本(Redundancy version，RV)不同，甚至M个数据连信道编码后的RV都是一样的。RV是指对传输数据进行信道编码后的不同冗余版本，一般来说，可以取信道版本{0，1，2，3}。同样的，M个信令(比如PDCCH或PUCCH)传输是repetition的，是指所述M个信令携带的内容是相同的，比如M个PDCCH携带的DCI内容是相同的(比如每个域的取值都相同)，比如M个PUCCH携带的内容取值是相同的。其中，M个repetition的数据(比如M个repetition PUSCH或M个repetition PDSCH)或者M个repetition的信令(比如M个repetition PUCCH或M个repetition PDCCH)可以来自M个 不同的TRP，或者来自M个不同的天线面板，或者M个不同的带宽部分(Bandwidth Part，BWP)，或者M个不同的载波组件(Carrier Component，CC)，其中所述的M个面板或者M个BWP或者M个CC可以属于同一个TRP，也可以属于多个TRP。

在本申请中，传输的时间单元可以包括一个或者多个符号的集合，比如一个时隙，或者一个迷你时隙。
在本申请所列的实施例中，如果没有说明，一般来说，包括1个终端和至少两个TRP(或者一个TRP中包括两个面板)，所述终端包括M个面板。M个面板分别传输M个PUSCH，所述M个PUSCH是repetition的，所述M个PUSCH可以来自M个终端或者M个面板，或者M个CC或者M个BWP，其中，所述的M个面板，或者M个CC或者M个BWP可以来自一个终端，也可以来自多 个终端。比如，一个面板或者一个端口组对应一个PUSCH传输，所述M个repetition的PUSCH可以是通过空分的方式，或者频分复用的方式，或者时分复用的方式传输。且基站配置的M个SRS resource set也可以替换成一个SRS resource set中的M个SRS resource组，其中，所述M个SRS resource包含的SRS resource互不重复或者重叠，M为大于1的整数。一实施例中，所述M取值为2，例如一个SRS resource set中包括SRS resource i，其中i＝0，1，2，3。其中，SRS resource0和SRS resource1分成一组，而SRS resource2和SRS resource3分成一组，本申请中的方法也可以用于上行物理控制信道。

基站和终端约定所述B1～B4中的任何一个表格，并做如下之一的约定：如果是表格B1或B2，那么在表格B1中在SRI的取值为小于或等于1的情况下，或者在表格B2的SRI取值小于3的情况下，表示终端只传输一个PUSCH，并且SRI对应第一个panel的发送波束，否则表示终端有两个重复的PUSCH发送，并且Panel0对应SRI的第一个取值，Panel1对应第二个SRI的取值，从而可以动态地从重复传输与非重复传输进行切换。
如果是表格B3，SRI的第一个值对应第一个panel的发送波束，SRI的第二个取值对应第二个panel的发送波束。如果是表格B4，那么SRI对应第一个panel的发送波束，并根据SRI的取值以及偏置的取值确定Panel1的SRI的取值。其中，偏置Offset的取值可以通过DCI的新增加的一个Offset域指示，也可以通过DCI的其它域隐含指示，比如通过天线端口域Antenna ports的取值确定Offset，例如天线端口取值于第一端口集合时(比如端口索引小于等于D，D为大于1的整数)Offset＝0；或天线端口取值于第二端口集合时(比如端口索引大于D)Offset＝1；比如通过Redundancy version域的取值确定Offset的取值。例如RV取值第一RV集合时(RV＝{0,1})Offset＝0；或，RV取值第一RV集合时(RV＝{0,1})Offset＝1。
而终端进行如下的步骤：
(1)接收基站配置的M个SRS resource set。
(2)根据所述M个SRS resource set配置，发送SRS resource。
(3)接收基站传输的1个DCI获取M个CSI，CSIi，i＝0，…，M-1。
终端通过接收所述一个DCI，并根据接收的基站配置的表格来确定每个panel的SRI信息。
如果基站配置的是表格B1或B2，那么在表格B1中当SRI的取值为小于或等于1的情况下，或者在表格B2的SRI取值小于3的情况下，表示终端只传输一个PUSCH，并且SRI对应第一个panel的发送波束，否则表示终端有两个重复的PUSCH发送，并且Panel0对应SRI的第一个取值，Panel1对应SRI的第二个取值，从而可以动态地从重复传输与非重复传输进行切换。
如果是表格B3，SRI的第一个值对应第一个panel的发送波束，SRI的第二个取值对应第二个panel的发送波束。如果是表格B4，那么SRI对应第一个panel的发送波束，并根据SRI的取值以及偏置的取值确定Panel1的SRI的取值。其中，偏置Offset的取值可以通过DCI的另外一个新增加的Offset域指示，也可以通过DCI的其它域隐含指示，比如通过天线端口域Antenna ports的取值确定Offset，例如天线端口取值于第一端口集合时(比如端口索引小于等于D，D为大于1的整数)Offset＝0；或天线端口取值于第二端口集合时(比如端口索引大于D)Offset＝1；比如通过Redundancy version域的取值确定Offset的取值。例如RV取值第一RV集合时(RV＝{0,1})Offset＝0；或RV取值第一RV集合时(RV＝{0,1})Offset＝1。
在本实施例中，基站指示的CSI中如果包括TPMI信息，需要在预编码信息和层数域对应的表格中增加一些新的条目，所述条目中指示的预编码中，第1至L1列表示第一个panel传输的PUSCH的预编码，而第L1+1～L列表示第二个panel传输的PUSCH的预编码。其中，第一个panel对应传输L1层，而第二个panel对应传输L-L1层。L1可取值1，2。而L可取值2，3，4，且L-L1大于0，比如L＝2时，L1＝1，一个panel传输1层。
本实施例中的M个SRS resource set也可以替换成一个SRS resource set的多个SRS resource组，SRI是用于指示基站选择的SRS resource set中的SRS resource，而传输PUSCH的发送波束或者预编码可以和SRI指示的SRS resource的发送波束或者预编码相同，从而可以认为SRI指示了PUSCH对应的发送波束或者预编码。
在一个实施例中，所述信令信息包括一个下行控制信息，所述下行控制信息中的上行探测信号资源指示域指示M个上行探测信号资源指示组，所述M个上行探测信号资源指示组用于确定M个物理上行信道的信道状态信息。
示例性的，信令信息包括一个下行控制信息。1个DCI指示M个面板Panel 传输的PUSCH的CSI(包括但不限于SRI)，上行传输时基于非码本(non codebook based)的传输方式。
在本实施例的系统中，包括1个终端和至少两个TRP(或者一个TRP中包括两个面板)，所述终端包括至少两个面板。M个DCI指示的M个面板分别传输M个PUSCH是repetition的。

上行探测信号资源指示在上行探测信号资源指示域中指示。信道秩为所述上行探测信号资源指示域指示的SRI总个数除以所述M。即所述信道秩为所述下行控制信息中的上行探测信号资源指示域指示的所有上行探测信号资源指示域SRI总个数除以M。
本示例用于说明基站如何通过1个DCI指示所述的M个PUSCH分别对应的CSI信息，以及终端如何根据接收的DCI信息确定所述M个CSI分别对应哪个面板传输的PUSCH，M为大于1的整数。对于基站来说，可以进行以下步骤的：
(1)基站配置M个SRS resource set，每个SRS resource set包括K个SRS resource。M，K为大于1的整数，比如M＝2，K＝2。
(2)基站接收终端传输的所述M个SRS resource set，并分别估计每个SRS resource set的最优CSI值。

如果是表格C1，在DCI中的SRS resource指示域的取值指示的的取值包括一个SRI组的情况下(为非画横线的行)，表示终端只传输一个PUSCH，并且SRI对应第一个panel的发送波束和层数，否则表示终端有两个重复的PUSCH发送，并且分号“；”左边表示第一个panel对应的SRI0取值，而分号右边表示第二个panel对应的SRI1的取值，根据SRI所在的行就可以动态地从重复传输与非重复传输进行切换。
如果是表格C2，分号“；”左边表示第一个panel对应的SRI0取值，而分号右边表示第二个panel对应的SRI1的取值，根据所述SRI的取值从而得到每个panel对应的发送波束(或者预编码)和层数。因为每个面板传输的PUSCH使用的发送波束或者预编码域对应的SRI指示的SRS resource使用相同的发送波束或者预编码，所以知道了每个面板的SRI的取值，就可以知道所述面板传输PUSCH的发送波束或者预编码。并且每个面板的传输层数可以为总SRI的个数除以M确定，或者根据所述面板对应的那组SRI包括的SRI的个数确定。

比如上述表格D2中M SRS＝4的第1行(0,1,2,3)，但每个SRS resource中包括了PanelID，如果SRS resource1和SRS resource2包括的是PanelID＝0，而SRS resource3，SRS resource4包括的PanelID为1，那么上述选择表示上行传输使用了两个panel，且panel0对应的SRS resource 0和SRS resource 1的波束传输PUSCH0，且为两层传输，而panel1对应的SRS resource2和SRS resource3的波束传输PUSCH1，且为两层传输。

在一个实施例中，基于所述信令信息确定M个物理上行信道的信道状态信息，包括如下至少之一：在M个下行控制信息中指示的信息之间的关系满足第一预定条件的情况下，确定所述M个物理上行信道的传输模式为重复传输；在M个下行控制信息所在的M个下行控制信道的参数之间的关系满足第二预定条件的情况下，确定所述M个物理上行信道的传输模式为重复传输。

示例性的，通过建立两个HAQR process的关联关系，以使得终端确定M个上行PUSCH是repetition的，其中，基站会通过M个DCI传输CSI信息。
基站对所述终端配置C个CORESET，并把所述的C个CORESET分成M个CORESET group，其中，所述的CORESET中包括高层参数标识的索引(比如CoresetGroupID)用于标识所述的CORESET属于哪个CORESET group，C和M为大于1的正整数，且C大于或等于M，比如C＝M＝2，其中，一个CORESET group对应一个终端上行传输单元(比如panel或者TRP的面板)。
本示例中基站传输的第i个PDCCH i-1对应第i个CORESET group，且第i个PDCCH i-1携带第i个DCI i-1，而第i个PDCCH i-1调度的第i个PUSCH i-1对应的HARQ进程索引取值于第i个进程索引集合HarqIndexSet i-1，i＝1，…，M。比如在M＝2时，第一个HARQ进程索引集合HarqIndexSet 0＝{0-7}，而HarqIndexSet 1＝{8-15}。RRC配置M个PDCCH分别调度的PUSCH对应的M个HarqIndexSet i-1，i＝1，…，M的关联关系，比如在M＝2时，约定HarqIndexSet 0中的第k个进程索引和HarqIndexSet 1中的第k+7个进程索引是有关联关系的，k＝0,…,7。基站和终端约定如果第i个DCI i-1调度的PUSCH对应的HARQ进程索引和j个DCI调度的PUSCH对应的HARQ进程索引有关联关系，那么就认为所述的两个DCI调度的PUSCH是repetion的，i，j＝1，…，M，且i不等于j，比如在M＝2时，i＝1，j＝2。
示例性的，M个PDCCH的信息确定M个上行PUSCH是repetition的，其中，基站会通过M个DCI传输CSI信息，主要通过进程号相同来确定M个PUSCH是repetion的。
基站对所述终端配置M个CORESET。基站传输的第i个PDCCH i-1对应第i个CORESET，且第i个PDCCH i-1携带第i个DCI i-1，而第i个PDCCH i-1调度的第i个PUSCH i-1对应的HARQ进程索引为K0，i＝1，…，M的，其中，K0为固定的值，取值为0～15中的任何一个整数。也就是说终端接收到M个DCI，如果他们调度的M个PUSCH对应的HARQ进程号都相同，那么就认为所述的M个DCI调度的PUSCH是repetion的。
可选的，所述M个PUSCH对应的panel有一个独立的缓冲用于缓存所述的M个进程。
在一个实施例中，基于所述信令信息确定M个物理上行信道的信道状态信息，包括：在M个下行控制信息满足如下至少之一的情况下，确定所述M个物理上行信道是重复传输的：
每个域是完全一致的；新数据取值域(New data indicator，NDI)取值相同；信道编码后的冗余版本域取值相同；调制编码方案域取值相同；混合自动重复传输进程数域取值相同；对应的控制资源集合有相同的搜索空间；对应的控制资源集合有相同的搜索空间集合；对应的物理下行控制信道检测时机相同；对 应的物理下行控制信道检测候选相同；上行探测信号资源指示域指示的上行探测信号资源指示个数为1，上行探测信号资源指示域指示的上行探测信号资源指示组数为1。
示例性的，通过M个PDCCH的信息确定M个上行PUSCH是repetition的，其中，基站会通过M个DCI传输CSI信息，主要通过DCI的域来确定其调度的M个PUSCH是repetion的。
基站对所述终端配置M个CORESET。基站传输的第i个PDCCH i-1对应第i个CORESET，且第i个PDCCH i-1携带第i个DCI i-1，如果基站配置的所述的M个DCI，或者说终端接收到的M个DCI满足如下条件至少之一：所述的M个DCI的每个域是完全一致的，所述的M个DCI的新数据取值域(New data indicator，NDI)取值相同，所述的M个DCI的RV域取值相同，所述的M个DCI的调制编码方案域(Modulation and coding scheme，MCS)取值相同，所述的M个DCI的HARQ进程数域(HARQ process number)取值相同，所述的M个DCI对应的CORESET有相同的搜索空间，所述的M个DCI对应的CORESET有相同的搜索空间集合，所述的M个DCI对应的PDCCH monitoring occasion相同，所述的M个DCI对应的PDCCH monitoring Candidate相同。
那么终端就认为所述M个DCI调度的M个PUSCH是repetion的。
如果所述M个PUSCH是repetition的，且在同一个时隙传输，那么就有如何确定它们传输时隙的问题，即是基于DCI1还是基于DCI0来算它们的传输时隙问题。
在一实施例中，该方法还包括以下至少之一：根据M个下行控制信息中的预定下行控制信息所在的时间单元确定所述M个物理上行信道所在的时间单元；根据M个下行控制信息中的预定下行控制信息所在的时间单元确定M个物理下行共享信道所在的时间单元；根据M个下行控制信息中的预定下行控制信息所在的时间单元确定M个上行探测参考资源所在的时间单元；根据M个下行控制信息中的预定下行控制信息所在的时间单元确定M个信道状态信息报告的时间单元。
在一实施例中，所述预定下行控制信息为如下至少之一：所述M个下行控制信息中传输时隙最小的下行控制信息；所述M个下行控制信息中传输时隙最大的下行控制信息；所述M个下行控制信息中主传输节点对应的下行控制信息；高层信令配置的下行控制信息；预定义的下行控制信息；所述M个下行控制信息对应的物理下行控制信道资源索引最小的下行控制信息；所述M个下行控制信息对应的物理下行控制信道资源索引最大的下行控制信息；所述M个下行控制信息对应的控制资源集合资源索引最小的下行控制信息；所述M个下行控制 信息对应的控制资源集合资源索引最大的下行控制信息。
示例性的，基站传输的M个DCI可能是在不同的时隙，而它们调度的资源是在同一个时隙传输，如何确定所述M个资源的传输时隙，所讲的资源包括但不限于以下之一：PUSCH，PDSCH，导频参考信号，PUCCH，CSI报告，即report。
终端在接收到DCI时，需要在相应的PDCCH监测时机(PDCCH monitoring occasion)检测多个候选的PDCCH，这需要一定处理时间，在获得PDCCH对应的DCI内容后，又需要一定时间来解调下行数据或者处理和填充要发送的上行数据或者信号。比如需要时间来解调PDSCH，要时间来处理要发送的PUSCH、PUCCH，以及进行CSI反馈。所以一般来说在基站传输DCI信令的时隙m和所述DCI调度的资源时隙k有一定的偏置O，这个偏置的定义既要考虑终端的能力，又要考虑系统延迟，需要做一个较好的平衡。在无线通信标准中一般都有一个固定的配置值。
为了提高可靠性，TRP或者终端可能重复repetion地传输一个信道或者信号。如果所述的M个DCI的内容是repetion的，从而他们调度资源(PUSCH，PDSCH，导频参考信号，PUCCH)在同一个时隙传输，或者M个DCI的内容可以不同，但调度的资源在同一个时间单元传输，比如是频分复用重复的，即M个所述的资源是在同一个时间单元传输，但占用不同的物理资源块(Physical Resource Block，PRG)。其中，PRB可以分成不同的组或者集合，每个PRB组或者集合包括至少一个PRB，比如如下之一的概念：子带，带宽部分，PRB绑定(bundling)，资源块组(Resource Block Group，RBG)，时间单元包括一个或者多个符号的集合，比如可以是时隙，迷你时隙，其中，时隙slot是包括多个符号的集合，一般为一个调度的本时间单位，一般来说在正常循环前缀下一个时隙包括14个符号，在扩展循环前缀下一个时隙包括12个符号，时隙也可以是迷你时隙mini slot，一个slot里可以包括至少一个mini slot。
如果M个DCI在不同的时隙传输，比如第i个DCI传输的时隙为m i，按相关技术，它们调度的资源会分别在第m i+O时隙传输，其中，i＝1,…,M，m i为互不相同的正整数，而O为高层参数配置的正整数或者固定的正整数，表示DCI的传输时隙和DCI调度的资源的时隙偏置。而如果M个DCI调度的资源要在同一个时隙传输，就会出现问题。
一种办法是引入预定DCI，所述的预定DCI用于计算所述M个DCI调度的资源和预定DCI的时隙问题，当然也可以是预定PDCCH，所述的预定PDCCH用于携带所述的预定DCI。
比如预定DCI的传输时隙为m，那么所述M个DCI调度的资源的时隙为

μ 1,μ PDCCH,O分别表示DCI调度的资源所对应的载波间隔配置参数，传输预定DCI所对应的载波间距配置参数，DCI调度的资源相对于传输预定DCI的时隙偏置，
