BEAM APPLICATION METHOD AND DEVICE Russian patent published in 2025 - IPC H04W72/04 

FIELD: communication technique.

SUBSTANCE: beam application method performed by a terminal includes: receiving downlink control information (DCI) from a network device, wherein the DCI comprises a unified transmission configuration indication state; and determining an uplink (UL) beam application time and/or a downlink (DL) beam application time corresponding to the unified state of the TCI transmission configuration. Said beam application time for UL transmission and/or beam application time for DL transmission is time after transmission time of response in form acknowledge symbol (ACK) of hybrid automatic repeat request (HARQ) for DCI with multiple symbols in between. Thus, coordination between beams of a network device and beams of a terminal is ensured, due to which transmission efficiency is increased.

EFFECT: ensuring consistency between beams of a network device and beams of a terminal device, which increases transmission efficiency.
