METHOD AND DEVICE FOR DETERMINING TRANSMISSION CONFIGURATION INDICATION, TERMINAL AND DATA MEDIUM Russian patent published in 2025 - IPC H04W72/12 

FIELD: communication technique.

SUBSTANCE: method for determining a transmission configuration indication (TCI) performed by a terminal includes receiving M instances of downlink control information (DCI) from a network device, each of the M DCI comprising a TCI state and the M DCI comprising a reference DCI, where M is a positive integer. Determination of the state of the combined TCI used for transmission is carried out based on the target state of the TCI contained in the reference DCI. Hybrid automatic repeat request (HARQ-ACK) acknowledgment codebook (HARQ-ACK) transmission to the network device contains HARQ-ACK information corresponding to M DCI, respectively.

EFFECT: determining a combined indication of a TCI transmission configuration which is used during transmission such that a terminal and a network device reach an agreement on the time of using the TCI state, wherein beam coherence is ensured, which improves transmission characteristics based on TCI between the terminal and the network device.
