METHODS AND DEVICES FOR PERFORMING UPLINK TRANSMISSION IN A SHARED DOWNLINK CHANNEL OCCUPANCY TIME

摘要

A method for performing uplink transmission by a user equipment (120) within a downlink channel occupancy time (DL COT) shared by a base station (110). The method includes obtaining a first indication about an uplink transmission starting point allocated by the base station; obtaining a second indication about a channel sensing type to apply to be allowed to intiate the uplink transmission; obtaining a third indication about a channel sensing position selected by the base station amongst one or more candidate positions (Ti); applying channel sensing based on said second and third indications during a channel sensing duration (D0); initiating uplink transmission after the channel sensing duration, if allowed, in advance to the allocated starting point by: a first time duration (D1) which compensate for the propagation time, and a second time duration (D2) which fills at least part of the time gap (G) between the end of the channel sensing duration (Ti+D0) and the beginning of the first time duration (T0-D1).
