COMMUNICATION METHOD AND DEVICE Russian patent published in 2024 - IPC H04W74/833 

FIELD: physics.

SUBSTANCE: invention relates to communication means. When it is determined that a persistent uplink LBT failure occurs in the first BWP of the first cell, the terminal-side device may indicate to the network device, using an uplink resource in a second cell, persistent uplink LBT failure occurs in the first cell. Device at the terminal side indicates, using a second cell, in which a persistent uplink LBT failure occurs, that a persistent uplink LBT failure occurs in the first cell, so that the network side device can more quickly determine that a persistent uplink LBT failure occurs in the first cell.

EFFECT: reduced time for elimination of eavesdropping before transmission (LBT).
