本申请实施例的端口确定方法，终端可以确定上行传输所采用的模式，并根据该模式，确定上行传输的DMRS端口。由此，可以从终端传输模式的角度来解读DMRS端口，从而满足不同传输模式下的DMRS端口指示需求。
可选的，在本申请实施例中，若终端的上行传输所采用的模式为SDM或SFN，可以采用以下至少一项来确定上行传输的DMRS端口(port)：
1)终端根据解读DMRS端口的第一表，确定上行传输的第一DMRS端口，所述第一表与多个探测参考信号(Sounding Reference Signal，SRS)资源指示(SRS Resource Indicator，SRI)域指示的秩之和相关，或者，所述第一表与多个传输预编码矩阵指示(Transmitted Precoding Matrix Indicator，TPMI)域指示的秩之和相关。即，终端可以根据接收到的多个探测参考信号资源指示SRI域指示的秩之和，或者根据接收到的多个传输预编码矩阵指示TPMI域指示的秩之和，确定用于解读DMRS端口的第一表，并根据第一表，确定上行传输的第一DMRS端口。
一些实施例中，在模式SDM下，如果网络侧指示了终端的上行传输关联多个目标对象，则终端可根据接收到多个SRI域(如接收到的所有SRI域)指示的秩之和，或者根据接收到的多个TPMI域(如接收到的所有TPMI域)指示的秩之和，确定用于解读DMRS端口的第一表。
一些实施例中，在模式SFN下，如果终端的关联多个目标对象的传输具有正交的DMRS端口，且网络侧指示了终端的上行传输关联多个目标对象，则终端可根据接收到多个SRI域(如接收到的所有SRI域)指示的秩之和，或者根据接收到的多个TPMI域(如接收到的所有TPMI域)指示的秩之和，确定用于解读DMRS端口的第一表。
一些实施例中，上述多个SRI域和/或多个TPMI域可以携带在下行控制信息(Downlink Control Information，DCI)中，由网络侧设备发送给终端。
一些实施例中，终端在根据第一表，确定上行传输的第一DMRS端口时，具体为根据接收到的天线端口指示域，从第一表中选取上行传输的第一DMRS端口，即，第一DMRS端口为天线端口指示域指示的第一表中的DMRS端口。
例如，若多个TPMI/SRI域指示的秩之和为2，则第一表可以但不限于如下表1所示：
表1

参见表1，表1中的Value值与天线端口指示域相关，比如，天线端口指示域可以取值为表1中的Value值。若天线端口指示域取值为第一值，可以指示来自一个码分复用(Code Division Multiplexing，CDM)组(group)的DMRS端口0和1，例如该第一值对应Value 0；若天线端口指示域取值为第二值，可以指示来自两个CDM group的DMRS端口0和1，例如该第二值对应Value 1；若天线端口指示域取值为第三值，可以指示来自两个CDM group的DMRS端口2和3，例如该第三值对应Value 2；若天线端口指示域取值为第四值，可以指示来自两个CDM group的DMRS端口0和2，例如该第四值对应Value 3。
又例如，若多个TPMI域指示的秩之和为4，则第一表可以但不限于如下表2所示：
表2
参见表2，表2中的Value值与天线端口指示域相关，比如，天线端口指示域可以取值为表2中的Value值。若天线端口指示域取值为第一值可以指示来自两个CDM group的DMRS端口0-3，例如该第一值对应Value 0。
2)终端根据解读DMRS端口的第二表，确定上行传输的第二DMRS端口，所述第二表与目标TPMI域指示的秩相关。即，终端可以根据接收到的目标TPMI域指示的秩，确定用于解读DMRS端口的第二表，并根据第二表，确定上行传输的第二DMRS端口。
一些实施例中，在模式SDM下，如果网络侧指示了终端的上行传输关联一个目标对象，则终端可根据接收到的目标TPMI域指示的秩，确定用于解读DMRS端口的第二表。
一些实施例中，在模式SFN下，如果终端的关联多个目标对象的传输具有正交的DMRS端口，且网络侧指示了终端的上行传输关联一个目标对象，则终端可以根据接收到的目标TPMI域指示的秩，确定用于解读DMRS端口的第二表。
一些实施例中，在模式SFN下，如果终端的关联多个目标对象的传输具有相同的DMRS端口，则终端根据接收到的目标TPMI域指示的秩，确定用于解读DMRS端口的第二表。
一些实施例中，上述目标TPMI域为终端接收到的第一个TPMI域。
一些实施例中，上述目标TPMI域可以携带在DCI中，由网络侧设备发送给终端。
一些实施例中，终端在根据第二表，确定上行传输的第二DMRS端口时，具体为根据接收到的天线端口指示域，从第二表中选取上行传输的第二DMRS端口，即，第二DMRS端口为天线端口指示域指示的第二表中的DMRS端口。
例如，若目标TPMI域指示的秩为2，则第二表可以但不限于如下表3所示：
表3
参见表3，表3中的Value值与天线端口指示域相关，比如，天线端口指示域可以取值为表3中的Value值。若天线端口指示域取值为第一值，可以指示来自一个CDM group的DMRS端口0和1，例如该第一值对应Value 0；若天线端口指示域取值为第二值，可以指示来自两个CDM group的DMRS端口0和1，例如该第二值对应Value 1；若天线端口指示域取值为第三值，可以指示来自两个CDM group的DMRS端口2和3，例如该第三值对应Value 2；若天线端口指示域取值为第四值，可以指示来自两个CDM group的DMRS端口0和2，例如该第四值对应Value 3。
可选的，在本申请实施例中，当上述1)中确定的第一DMRS端口包括：来自不同码分复用(Code Division Multiplexing，CDM)组(group)的多个DMRS端口时，终端可以确定其上行传输关联多个目标对象，并针对该多个目标对象，利用该多个DMRS端口进行上行传输。

模式1：SDM
模式1-1：如图3A所示，终端的上行传输关联TRP0和TRP1，具有一个CW，冗余版本(Redundancy Version，RV)为RV0，则：
(1)如果网络侧指示了关联两个目标对象传输，则DMRS端口的解读由接收到的两个SRI域/TPMI域指示的秩rank之和决定，且只能指示来自两个CDM group的DMRS端口；如果网络侧指示了关联一个目标对象传输，则DMRS端口的解读由接收到的第一个TPMI域指示的rank决定。
(2)在DMRS端口的解读由接收到的两个SRI域/TPMI域指示的rank之和决定的情况下，如果指示了来自不同CDM group的多个DMRS端口，则表明为MTRP传输，而如果指示来自相同的CDM group的多个DMRS端口，则表示切换到STRP传输，并根据接收到的第一个TPMI域指示的rank解读DMRS端口，或取已指示的来自相同CDM group的多个DMRS端口的前N个DMRS端口进行上行传输，其中N基于第一个TPMI域指示的rank确定。
模式1-2：如图3B所示，终端的上行传输关联TRP0和TRP1，具有两个CW，此时对DMRS端口的解读与模式1-1相同，在此不再赘述。
模式2：FDM
模式2-1：如图3C所示，终端的上行传输关联TRP0和TRP1，具有一个CW/1RV，TRP0和TRP1对应不同的物理资源块(Physical Resource Block，PRB)资源，则：DMRS 端口的解读由接收到的第一个TPMI域指示的rank决定，两个TRP对应相同的DMRS端口组，即两个TRP分别对应相同的多个DMRS端口。
模式2-2：如图3D所示，终端的上行传输关联TRP0和TRP1，具有一个CW，TRP0和TRP1对应不同的物理资源块(PRB)资源，TRP0和TRP1分别具有RV0和RV1，则：DMRS端口的解读由接收到的第一个TPMI域指示的rank决定，两个TRP对应相同的DMRS端口组，即两个TRP分别对应相同的多个DMRS端口。
模式2-3：如图3E所示，终端的上行传输关联TRP0和TRP1，具有两个CW，TRP0和TRP1对应不同的物理资源块(PRB)资源，TRP0和TRP1分别具有CW0和CW1，则：DMRS端口的解读由接收到的两个TPMI域指示的rank中的较大者决定，rank小的TPMI域对应的TRP取天线端口指示域指示的相应表中DMRS端口的前M个DMRS端口，M基于此rank小的TPMI域指示的rank确定。
模式3：SFN
模式3-1：如图3F所示，终端的上行传输关联TRP0和TRP1，具有一个CW，TRP0和TRP1具有相同的RV0，则：
(1)如果TRP0和TRP1对应相同的DMRS端口，则DMRS端口的解读由接收到的第一个TPMI域指示的rank决定，两个TRP对应相同的DMRS端口组，即两个TRP分别对应相同的多个DMRS端口。
(2)如果TRP0和TRP1对应正交的DMRS端口，则与模式SDM下的行为类似，在此不再赘述。
可选的，上述步骤22中的确定上行传输的DMRS端口可以包括：终端根据解读DMRS端口第五表，确定上行传输的DMRS端口，所述第五表包含至少一个第一条目，所述第一条目用于指示关联多个目标对象的上行传输的多个DMRS端口。也就是说，本实施例中确定的用于解读DMRS端口的表可以包含至少一个第一条目，此第一条目指示关联多个目标对象的上行传输的多个DMRS端口。
例如，上述的第五表可以如下但不限于表4所示：
表4
在表4中，第一条目为Value 4对应的条目，指示了关联两个目标对象的上行传输的两个DMRS端口，即指示了DMRS端口0和2。
又例如，上述的第五表可以但不限于如下表5所示：
表5
在表5中，第一条目包括Value 12和Value 13对应的条目，指示了关联两个目标对象的上行传输的两个DMRS端口，其中，Value 12对应的条目指示了DMRS端口0和2，Value 13对应的条目指示了DMRS端口4和6。
又例如，上述的第五表可以但不限于如下表6所示：
表6
在表6中，第一条目包括Value 12对应的条目，指示了关联两个目标对象的上行传输的两个DMRS端口，其中，Value 12对应的条目指示了DMRS端口0和2，来自两个CDM group。
可选的，在本申请实施例中，可以基于接收到的天线端口指示域，确定上行传输的DMRS端口。上述步骤22可以包括：终端根据所述模式，以及接收到的天线端口指示域， 确定上行传输的第五DMRS端口。也就是说，在确定上行传输所采用的模式之后，可以先根据该模式，确定用于解读DMRS端口的表，然后根据该表来解读接收到的天线端口指示域，确定上行传输的DMRS端口。
可选的，当终端的上行传输关联多个目标对象时，上述的第五DMRS端口可包括：天线端口指示域指示的多个DMRS端口，该多个DMRS端口来自不同或相同的CDM组。比如，在上行传输采用SDM的情况下，该多个DMRS端口来自不同的CDM组；或者，在上行传输采用FDM的情况下，该多个DMRS端口来自相同的CDM组。
例如，天线端口指示域的比特长度可以为3比特或4比特，以指示上行传输的DMRS端口。比如，在基于上述表1解读DMRS端口的情况下，若终端的上行传输关联多个目标对象，可以指示Value 4对应的条目中的DMRS端口0和2；或者，在基于上述表2解读DMRS端口的情况下，若终端的上行传输关联多个目标对象，可以指示Value 12对应的条目中的DMRS端口0和2，也可以指示Value 13对应的条目指示了DMRS端口4和6。
可选的，若终端的上行传输关联多个目标对象，终端可以根据协议约定，确定该上行传输的多个DMRS端口。例如，关联多个目标对象的PUSCH传输的DMRS端口组(即多个DMRS端口)由协议约定，如{0，2}，关联一个目标对象的PUSCH传输的DMRS端口由天线端口指示域指示，则当PUSCH被调度为关联多个目标对象传输时，可确定PUSCH传输的DMRS端口为0和2，而忽略指示DMRS端口的天线端口指示域。
可选的，若终端的上行传输关联多个目标对象，终端可以根据接收到的天线端口指示域指示的一个DMRS端口，确定该上行传输的包含该一个DMRS端口的多个DMRS端口。例如，PUSCH传输关联多个目标对象，预设了多个DMRS端口组，比如(0,2)、(1,3)、(4,6)和(5,7)，若接收到的天线端口指示域指示了DMRS端口0，则可以确定PUSCH传输的DMRS端口包括DMRS端口0和2；而若接收到的天线端口指示域指示了DMRS端口4，则可以确定PUSCH传输的DMRS端口包括DMRS端口4和6。
可选的，在多个目标对象一一与多个CDM组关联，即多个目标对象分别与多个CDM group关联的情况下，终端可以根据其上行传输的DMRS端口所属的CDM组，确定该上行传输关联的目标对象。例如，第一CDM group与第1目标对象关联，第二CDM group与第2目标对象关联，则：若仅指示了第一CDM group的DMRS端口，即终端的PUSCH传输的DMRS端口属于第一CDM group，则PUSCH传输关联第1目标对象；或者，若仅指示了第二CDM group的DMRS端口，即终端的PUSCH传输的DMRS端口属于第二CDM group，则PUSCH传输关联第2目标对象；或者，若同时指示了第一CDM group和第二CDM group的DMRS端口，即终端的PUSCH传输的多个DMRS端口来自不同的两个CDM group，则PUSCH传输关联第1目标对象和第2目标对象。
可选的，若终端的上行传输采用关联多个目标对象的传输方式，该传输方式可以通过以下至少一项使能：
无线资源控制RRC配置；即，通过RRC配置指示终端的上行传输关联多个目标对象；
对应多个目标对象的TCI状态生效；即，在当前有对应多个目标对象的TCI状态生效时，使能关联多个目标对象的上行传输；
调度上行传输的DCI指示；即，通过调度上行传输的DCI指示该上行传输关联多个目标对象；
网络侧指示了来自不同CDM组的DMRS端口；即，通过指示来自不同CDM组的DMRS端口，指示相应上行传输关联多个目标对象。
