下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的信息传输方法、装置、终端及可读存储介质进行详细地说明。
请参见图2，图2是本申请实施例提供的一种信息传输方法的流程图，该方法由终端执行，如图2所示，该方法包括如下步骤：
步骤21：终端根据第一TPMI域，确定第一PTRS端口以及第一PTRS端口对应的传输层或DMRS端口。
本实施例中，第一传输预编码矩阵指示(Transmit Precoding Matrix Indicator，TPMI)域，又称为预编码信息和层数(Precoding information and number of layers)域，为与终端的上行传输关联的目标对象关联的TPMI域，即第一TPMI域是与终端的上行传输关联的目标对象关联。第一PTRS端口为终端实际使用的PTRS端口。
TPMI域与目标对象关联可以包含：多个目标对象分别对应多个TPMI域，或者一个目标对象对应一个TPMI域，或者多个目标对象对应一个TPMI域，或者一个目标对象关联多个TPMI域。
可选的，上述上行传输可包括但不限于物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输、物理上行控制信道(Physical Uplink Control Channel，PUCCH)传输等。
一些实施例中，第一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，上述终端可被配置了多个PTRS端口，第一PTRS端口为该多个PTRS端口中的部分或全部PTRS端口。比如，第一PTRS端口可以为一个PTRS端口。
步骤22：终端利用第一PTRS端口以及第一PTRS端口对应的传输层或DMRS端口，进行上行传输。
本实施例中，由于可能存在终端实际使用的PTRS端口(即第一PTRS端口)对应多个传输层或DMRS端口的情况，因此在确定第一PTRS端口对应的传输层或DMRS端口之后，终端可以根据接收到的PTRS-DMRS关联指示域，从第一PTRS端口对应的传输层或DMRS端口中，选择第一PTRS端 口关联的传输层或DMRS端口(如关联的一个传输层/DMRS端口)，并利用第一PTRS端口以及第一PTRS端口关联的传输层或DMRS端口，进行上行传输。
需指出的，本实施例中所涉及的目标对象为与上行数据传输相关的参数。例如，所述目标对象可以是包括：波束(beam)、发射接收点(Transmission and Reception Point，TRP)、天线面板(panel)、传输配置指示(Transmission Configuration Indicator，TCI)状态、TCI状态池、空间关系(spatial relation)、探测参考信号(Sounding Reference Signal，SRS)资源、SRS资源配置的SRS端口，SRS资源集、参考信号、路损参考信号等，也可指某些特定的指示域如SRS资源指示域。
其中，所述天线面板，也可以称为以下之一：天线组、天线端口组、天线集合、天线端口集合、波束集合、波束子集合、天线阵列、天线端口阵列、天线子阵列、天线端口子阵列、逻辑实体、实体或天线实体、天线面板实体(panel entity)、定时误差组(timing error group，TEG)、终端能力值、终端能力值集合等。
可选的，所述天线面板包括对应的panel标识，所述panel标识可以包括以下至少一项：天线面板的标识、参考信号资源标识、参考信号资源集标识、TCI状态标识、准共址(Quasi co-location，QCL)信息标识、空间关系标识、终端能力值索引、终端能力值集合索引等。
本实施例中所涉及的波束信息，也可以称为以下之一：波束的标识信息、空间关系(spatial relation)信息、空域发送滤波器(spatial domain transmission filter)信息、空域接收滤波器(spatial domain reception filter)信息、空域滤波器(spatial filter)信息、传输配置指示状态(TCI state)信息、QCL信息、QCL参数等。其中，下行波束信息通常可使用TCI state信息或QCL信息表示，上行波束信息通常可使用TCI state信息表示。
一些实施例中，上述终端的上行传输可以与多个目标对象(如TCI状态)关联，此时终端处于多panel场景中，这里与目标对象关联也可以理解为应用目标对象进行传输，或者对目标对象进行预编码后传输。
另一些实施例中，上述终端的上行传输可以与一个目标对象(如panel) 关联。
本申请实施例的信息传输方法，终端可以根据与其上行传输关联的目标对象关联的第一TPMI域，确定第一PTRS端口以及其关联的传输层，并利用该第一PTRS端口以及其关联的传输层进行上行传输，该第一PTRS端口为终端实际使用的PTRS端口。由此，可以实现终端确定其实际使用的PTRS端口，从而有效保证PTRS传输性能。
可选的，在本申请实施例中，第一PTRS端口可以为第一TPMI域指示的上行传输天线端口对应的PTRS端口，第一PTRS端口对应的传输层(layer)可以为第一TPMI域指示的上行传输天线端口对应的部分或全部传输层，第一PTRS端口对应的DMRS端口可以为第一TPMI域指示的上行传输天线端口对应的部分或全部DMRS端口。
例如，终端配置了PTRS端口0和PTRS端口1，PUSCH天线端口1000和1002关联/共享PTRS端口0，PUSCH天线端口1001和1002关联/共享PTRS端口1，由PUSCH天线端口1000和1002传输的传输层关联PTRS端口0，由PUSCH天线端口1001和1002传输的传输层关联PTRS端口1，则：如果与PUSCH传输关联的目标对象关联的第一TPMI域指示了PUSCH天线端口1001和1002，则可以确定第一PTRS端口(即终端实际使用的PTRS端口)为PTRS端口1，第一PTRS端口对应的layer为由PUSCH天线端口1001和1002传输的多个layer，即PUSCH天线端口1001和1002对应的全部layer；而如果与PUSCH传输关联的目标对象关联的第一TPMI域指示了PUSCH天线端口1000和1002，则可以确定第一PTRS端口(即终端实际使用的PTRS端口)为PTRS端口0，第一PTRS端口对应的layer为由PUSCH天线端口1000和1002传输的多个layer，即PUSCH天线端口1001和1002对应的全部layer。
又例如，假设在8天线(8Transport，8Tx)的情况下，终端配置了PTRS端口0和PTRS端口1，PUSCH天线端口分为两组，即第一组端口和第二组端口，第一组端口对应多个layer，第一组端口关联PTRS端口0，且PTRS端口0仅对应第一组端口的前2个layer传输，第二组端口对应多个layer，第二组端口关联PTRS端口1，且PTRS端口1仅对应第二组端口的前2个layer 传输，则：如果与PUSCH传输关联的目标对象关联的第一TPMI域指示了第一组端口，则可以确定第一PTRS端口(即终端实际使用的PTRS端口)为PTRS端口0，第一PTRS端口对应的layer为第一组端口的前2个layer，即第一组端口对应的部分layer；或者，如果与PUSCH传输关联的目标对象关联的第一TPMI域指示了第二组端口，则可以确定第一PTRS端口(即终端实际使用的PTRS端口)为PTRS端口1，第一PTRS端口对应的layer为第二组端口的前2个layer，即第二组端口对应的部分layer；或者，如果与PUSCH传输关联的目标对象关联的第一TPMI域指示了第一组端口和第二组端口，则可以分别确定第一PTRS端口(即终端实际使用的PTRS端口)为PTRS端口0和1，相应layer为第一组端口对应的部分layer和第二组端口对应的部分layer。
例如，若收到的PTRS-DMRS关联指示域包含3bit，PTRS端口0对应8个传输层/DMRS端口，则可以基于该PTRS-DMRS关联指示域，从该8个传输层/DMRS端口中选出一个传输层/DMRS端口作为PTRS端口0的关联传输层/DMRS端口。
又例如，若收到的PTRS-DMRS关联指示域包含2bit，PTRS端口0对应8个传输层/DMRS端口，则可以基于该PTRS-DMRS关联指示域，从该8个传输层/DMRS端口中的前4个传输层/DMRS端口选出一个传输层/DMRS端口作为PTRS端口0的关联传输层/DMRS端口。
又例如，若收到的PTRS-DMRS关联指示域包含4bit，其中前2比特指示从对应PTRS port 0的4个传输层/DMRS端口中选出一个传输层/DMRS端口作为PTRS端口0的关联传输层/DMRS端口，后2比特指示从对应PTRS port 1的4个传输层/DMRS端口中选出一个传输层/DMRS端口作为PTRS端口0的关联传输层/DMRS端口。
又例如，若收到的PTRS-DMRS关联指示域包含2bit，其中前1比特指示从对应PTRS port 0的4个传输层/DMRS端口中的前2个传输层/DMRS端口选出一个传输层/DMRS端口作为PTRS端口0的关联传输层/DMRS端口，后1比特指示从对应PTRS port 1的4个传输层/DMRS端口中的前2个传输层/DMRS端口选出一个传输层/DMRS端口作为PTRS端口0的关联传输层 /DMRS端口。
可选的，若终端的上行传输关联多个目标对象，可以采用以下至少一项来确定第一PTRS端口以及第一PTRS端口关联的传输层：
1)终端针对每个目标对象，根据关联该目标对象的第一TPMI域，确定第一PTRS端口以及第一PTRS端口对应的传输层或DMRS端口。这样在多目标对象(比如panel)场景下，可以在不引入新的PTRS端口的情况下，实现per-panel的PTRS端口确定。
例如，若终端的PUSCH传输关联两个目标对象，比如第一目标对象和第二目标对象，则对于第一目标对象，根据关联该第一目标对象的第一TPMI域，确定终端实际使用的PTRS端口以及关联的传输层，和，对于第二目标对象，根据关联该第二目标对象的第一TPMI域，确定终端实际使用的PTRS端口以及关联的传输层。
2)终端根据关联多个目标对象中的任一者的第一TPMI域，确定第一PTRS端口以及第一PTRS端口对应的传输层或DMRS端口。这样在多目标对象(比如panel)场景下，可以在不引入新的PTRS端口的情况下，实现per-panel的PTRS端口确定。
例如，若终端的PUSCH传输关联两个目标对象，比如第一目标对象和第二目标对象，则可以根据关联第一目标对象或第二目标对象的第一TPMI域，确定终端实际使用的PTRS端口以及对应的传输层，此确定的PTRS端口以及关联的传输层适用于第一目标对象和第二目标对象。这里关联第一目标对象或第二目标对象的第一TPMI域也可以描述为第一个TPMI域和第二个TPMI域。
可选的，若终端的上行传输关联一个目标对象，则终端根据关联该一个目标对象的第一TPMI域，确定第一PTRS端口以及第一PTRS端口关联的传输层，从而确定终端实际使用的PTRS端口以及关联的传输层。
可选的，若终端配置了多个PTRS端口，终端的上行传输关联多个目标对象，则该多个PTRS端口与多个目标对象一一对应，每个PTRS端口与其对应的目标对象所关联的第一传输层关联，第一传输层包含至少一个传输层。
例如，若终端配置了PTRS端口0和PTRS端口1，终端的PUSCH传输 关联两个目标对象，比如第一目标对象和第二目标对象，则：PTRS端口0和PTRS端口1与第一目标对象和第二目标对象一一对应，每个PTRS端口与其对应的目标对象所关联的第一传输层关联，第一传输层包含至少一个传输层。比如，PTRS端口0与第一目标对象对应，PTRS端口1与第二目标对象对应，第一目标对象关联第1传输层，第二目标对象关联第2传输层，则PTRS端口0与第一目标对象关联的第1传输层关联，PTRS端口1与第二目标对象关联的第2传输层关联，其中，第1传输层和第2传输层分别包含至少一个传输层。
可选的，若终端配置了多个PTRS端口，且终端的上行传输关联多个目标对象中的一个目标对象，则终端可以将该多个PTRS端口中的预设PTRS端口或默认PTRS端口确定为第一PTRS端口，从而确定终端实际使用的PTRS端口及关联的传输层。
例如，若终端配置了PTRS端口0和PTRS端口1，终端的PUSCH传输关联一个目标对象，则终端实际使用的PTRS端口可以为预设的PTRS端口0或PTRS端口1，或者为默认的PTRS端口0或PTRS端口1；终端实际使用的PTRS端口关联与该一个目标对象关联的TPMI域指示的所有传输层。
可选的，若终端的上行传输关联一个目标对象，则终端根据关联该一个目标对象的第一TPMI域，确定第一PTRS端口以及第一PTRS端口关联的传输层，从而确定终端实际使用的PTRS端口以及关联的传输层。
本申请实施例中，为了有效保证PTRS传输性能，当终端的上行传输关联多个目标对象时，终端可以根据第一信息，确定第一PTRS端口(即实际使用的PTRS端口)的功率缩放因子，所述第一信息包括以下至少一项：
1)关联多个目标对象的上行传输采用的多个预编码矩阵的相干特性信息。
可选的，上述相干特性信息由终端接收到的多个TPMI域和/或SRI域确定。
可选的，上述相干特性信息由多个TPMI域和/或SRI域中的预设TPMI域和/或SRI域确定，如由第一个TPMI域/SRI域确定。
2)关联多个目标对象的上行传输的PTRS端口数。
可选的，此2)中的PTRS端口数包括以下至少一者：关联多个目标对象 的上行传输调度的总的PTRS端口数、关联多个目标对象的上行传输分别关联的PTRS端口数。
3)关联多个目标对象的上行传输的传输层数。
可选的，此3)中的传输层数包括以下至少一者：
每个目标对象对应的传输层数；其中，此传输层数可以分别由每个目标对象关联的TPMI域和/或探测参考信号资源指示(SRS Resource Indicator，SRI)域确定；比如，每个目标对象对应的传输层数为：该目标对象关联的TPMI域/SRI域指示的传输层数；
多个目标对象对应的总的传输层数；其中，此总的传输层数可以由多个目标对象关联的TPMI域和/或SRI域确定；比如，该总的传输层数为：多个目标对象关联的多个TPMI域/SRI域指示的传输层数之和。
例如，PUSCH传输关联两个TCI状态，则对于每个TCI状态的PUSCH传输，实际使用的PTRS端口的功率缩放因子由所述TCI状态对应的TPMI域指示的传输层数、相干特性以及所述TCI状态对应的实际的PTRS端口数确定。
又例如，PUSCH传输关联两个TCI状态，则对于每个TCI状态的PUSCH传输，实际使用的PTRS端口的功率缩放因子由所述TCI状态对应的TPMI域指示的传输层数、相干特性、所述两个TCI状态对应的总的实际的PTRS端口数确定。
例如，以PUSCH传输为例，有关PTRS端口的功率缩放因子的解读可以如下表1所示：
表1

例如，PUSCH传输关联两个TCI状态，如果对于某TCI状态的PUSCH传输，由该TCI状态对应的TPMI域指示的传输层数为2，相干特性为全相干，则参见表1，可以确定相应PTRS端口的功率缩放因子为3；或者，如果对于某TCI状态的PUSCH传输，由该TCI状态对应的TPMI域指示的传输层数为3，相干特性为部分相干/非相干/非码本传输，实际调度的PTRS端口数为Qp，则参见表1，可以确定相应PTRS端口的功率缩放因子为3Qp-3；或者，如果对于某TCI状态的PUSCH传输，由该TCI状态对应的TPMI域指示的传输层数为4，相干特性为部分相干，实际调度的PTRS端口数为Qp，则参见表1，可以确定相应PTRS端口的功率缩放因子为3Qp。
