USER TERMINAL AND METHOD FOR RADIO COMMUNICATION Russian patent published in 2023 - IPC H04B7/06 H04B7/08 

FIELD: wireless communication.

SUBSTANCE: technical result is provided by the user terminal determining, provided that conditions (1) and (2) are met, the assumed quasi-colocation (QCL) of AP-CSI-RS based on the control resource set (CORESET) corresponding to the lowest CORESET identifier in the last slot wherein one or multiple CORESETs are monitored, and receiving the AP-CSI-RS signal by using the assumed QCL. Condition (1) consists in the scheduling interval between receiving the downstream control channel to communicate the downstream control information controlling the AP-CSI-RS signal and receiving the AP-CSI-RS signal being less than the value of the period for the communicated beam switching. Condition (2) consists in the fact that, in the symbol identical to the AP-CSI-RS signal symbol, no other descending signals with said TCI state are present, and at least one of the following is present: a physical descending common channel with a scheduling interval less than threshold; and a AP-CSI-RS signal with a scheduling interval less than the value of the period for beam switching.

EFFECT: possibility of using the terminal to determine the transmission configuration indication state (TCI state) of the aperiodic channel state information reference signal (AP-CSI-RS).
