- the corresponding SRI field or TPMI field or antenna port indication field When the indicated part of the TCI status does not take effect, the corresponding SRI field or TPMI field or antenna port indication field also becomes ineffective accordingly. Therefore, the data flow indicated by the effective information field corresponds to all data flows indicated by the antenna port indication field.
- Option 5 Determine the corresponding data flow based on the indicated SRS resources
- the TPMI domain corresponding to the first SRS resource or the precoding indicated by TPMI corresponds to a lower data stream or port, such as layer 0 ⁇ (N 1 -1), and the TPMI domain corresponding to the second SRS resource or the precoding indicated by TPMI.

- the PUSCH port can also be the sum of the ports indicated by the two SRI fields, that is, the number of PUSCH ports is 6.
- the relationship between the PUSCH port and the SRI/TPMI/TCI indication can be determined by the corresponding relationship between the above SRI or TPMI indication and the antenna port indicated by the antenna port indication field. You only need to replace the port indicated by the port indication field with the PUSCH port. That’s it.

- the number of SRS resource ports in an SRS resource set can be different.
- the network side can use an SRI field to indicate an SRS resource.
- the SRS resource can be 2 ports or 4 ports.
- the precoding information corresponding to the SRS resource is indicated through the TPMI field.
- the SRS resource indicated by the SRI field has 1 spatial relationship or TCI, it means single TRP or single panel transmission, and the indicated spatial relationship or TCI status applies to all PUSCH ports or DMRS ports. If the SRS resource indicated by the SRI field has more than 1 spatial relationship, it means that multi-TRP or multi-panel SFN transmission is performed, and each PUSCH port or DMRS port uses the indicated multiple spatial relationships or TCI states for transmission.
- each SRS resource is 1 port, and the network side can use an SRI field to indicate one or more SRS resources. Similar to codebook-based transmission, each PUSCH port or DMRS port transmits using one or more spatial relationships or TCI states indicated.
- Method 2 The network side configures an SRS resource set for the UE, where each SRS resource has 1 or 2 or 3 or 4 spatial relationships or TCI states, through 1 SRI domain in the DCI And/or two or more TPMI domains (or two TPMI indications of one TPMI domain) indicate the precoding information for PUSCH transmission.
- the port equivalent to PUSCH transmission is only determined by the indicated SRS resource.
- two panels use the spatial relationship or TCI status of the indicated SRS resources to send PUSCH respectively, and the precoding matrices used by the two panels when transmitting can be Differently, two or more TPMI fields or precoding codewords corresponding to the TPMI indication are used to send PUSCH.
- the number of data streams indicated by two or more TPMI fields or TPMI indications is the same.
- the precoding codeword indicated by one TPMI field corresponds to a rank of 4
- the precoding codeword indicated by another TPMI field also corresponds to a rank of 4.
- the terminal determines to perform 4-stream data transmission, and for each data stream, two precoding codewords indicated by TPMI are used for precoding. For example, if the precoding codeword indicated by the TPMI field is W1, and the precoding codeword indicated by the second TPMI field is W2, then the terminal uses W1+W2 to send PUSCH.
- Method 3 The network side configures 2, 3, or 4 SRS resource sets for the UE, where each SRS resource has a spatial relationship or TCI state, and is paired with multiple SRI domains and/or multiple TPMI domains in the DCI.
- the precoding information transmitted by the PUSCH is indicated, or multiple SRS resources are indicated through an SRI domain and/or a TPMI domain, or multiple TPMI indications are indicated.
- the transmission framework is the same as the repeated transmission of PUSCH TDM. It has multiple SRS resource sets to facilitate dynamic switching between multiple transmission schemes on the network side.
- Each SRS resource set can be associated with a panel.
- the SRS resources in the SRS resource set can have the same number of ports, such as 2 or 4.
- the network side can indicate one SRS resource for transmission from each SRS resource set, and there can be multiple SRI domains. For example, when the number of SRS resource sets is 2, the network side can use 2 SRI fields to indicate 2 SRS resources.
- the number of ports of the SRS resources can be the same or different. For example, the number of ports of one SRS resource is 2, and the number of ports of the other SRS resource is 2. If it is 4, the UE can use the union of 2 SRS resource ports to send PUSCH.
- the spatial relationship or TCI status of the PUSCH port is also the union of the spatial relationship or TCI status of the indicated SRS resources.
- a TPMI domain can be used for precoding indication. The TPMI domain acts on a specified SRS resource, such as an SRS resource with more ports, or an SRS resource within a specific SRS resource set, or has a lower or lower SRS resources with higher SRS resource index, etc.
- SRS resource set can also correspond to different TRPs, and the SRS resources in the SRS resource set can have different ports.
- the network side configures the UE for SFN transmission, it can also limit the SRS resources indicated by multiple SRI domains to have the same number of ports to simplify the subsequent spatial relationship or TCI status determination process of PUSCH ports or DMRS ports.
- the network side instructs the UE to use an SRS resource set for transmission, for example, through the SRS resource set field, this is equivalent to the UE using a single panel to transmit to a single TRP.
- Different RBs can be used to transmit the same PUSCH, that is, different versions of a TB, or different RBs can be used to transmit different parts of the same TB to increase transmission reliability.
