Such as mobile phones (or "cellular" phones) and computers with terminal equipment. For example, they can be portable, pocket-sized, handheld, computer-built or vehicle-mounted mobile devices, which exchange languages and/or wireless access networks. Or data.

For multiple TRP scenarios in a wireless communication system, multiple TRPs can be divided into ideal backhaul lines (ideal backhaul) and non-ideal backhaul lines (non-ideal backhaul). For non-ideal backhaul lines, there is a large delay in information exchange between multiple TRPs, which is more suitable for independent scheduling. Multiple downlink control information (DCI) can be used to schedule multiple physical downlink shared channels (PDSCH) ), at this time, an Acknowledgement (ACK) message, a Negative Acknowledgement (NACK) message, and a CSI report can be fed back to each TRP respectively. For an ideal backhaul line, multiple TRPs can exchange scheduling information and UE feedback information in real time. In addition to scheduling multiple PDSCHs through the above-mentioned multiple DCIs, you can also schedule PDSCHs with a single DCI. At this time, ACK, NACK, and CSI reports can be sent to any A TRP gives feedback.

Multiple PDSCHs scheduled by multiple DCIs may not overlap, partially overlap, or completely overlap in time-frequency resources. On overlapping time-frequency resources, each TRP performs independent precoding according to its own channel, and the UE receives multi-layer data streams belonging to multiple PDSCHs in a non-coherent joint transmission (NCJT) manner.

For the case of the single DCI scheduling PDSCH of the ideal backhaul route, the following transmission modes may be included.

For example, the CSI report corresponding to CORESETPoolIndex=0 has priority over the CSI report corresponding to CORESETPoolIndex=1, regardless of the time domain characteristics of the CSI report; or the penultimate item compares the corresponding CORESETPoolIndex before comparing the serving cell ID (serving cell index) ; Or compare the corresponding CORESETPoolIndex before comparing the last reportConfigID; etc.

Optionally, in the method for determining the CSI report in the embodiment of the present invention, in the case where the above-mentioned CSI report configuration information can be used to determine the uplink channel for transmitting the CSI report, the uplink channel for transmitting the CSI report may include one of the following:

(1) Uplink channel for transmitting P-CSI report.
