1. A method for determining an occupancy time of a channel state information (CSI) processing unit, applied to a terminal device and comprising:
for a CSI report with CSI report configuration with report Quantity set to ‘none’ and a Channel State Information-Reference Signals (CSI-RS) resource set associated with the CSI report is not configured with higher-layer parameter trs-Info, determining an occupancy time of the CSI processing unit based on a time-domain characteristic of the CSI report;
wherein determining an occupancy time of the CSI processing unit based on a time-domain characteristic of the CSI report comprises:
when the time-domain characteristic of the CSI report is periodic or semi-persistent, determining that the occupancy time of the CSI processing unit starts from the 1st Orthogonal Frequency Division Multiplexing (OFDM) symbol of a CSI resource until Z′ OFDM symbols after the last OFDM symbol of the CSI resource;
when the time-domain characteristic of the CSI report is aperiodic, determining that the occupancy time of the CSI processing unit starts from the 1st OFDM symbol after a PDCCH triggering the CSI report until a later one between the first OFDM symbol and the second OFDM symbol, the first OFDM symbol is Z OFDM symbols after the 1st OFDM symbol that is after the PDCCH triggering the CSI report, and the second OFDM symbol is Z′ OFDM symbols after the last OFDM symbol of a CSI resource, wherein Z and Z′ are quantities related to OFDM symbols required for calculating CSI, and Z and Z′ are positive integers.
