Abstract
The present disclosure relates to a user equipment (UE) and base station (BS) involved in an improved physical random access channel, PRACH, transmission. The UE configures, based on a received unlicensed channel access configuration, symbols of an occupancy time of the respective unlicensed channel for uplink communication; receives an indication of a timing of channel resources which are to be used for a PRACH transmission; determines whether or not the indicated timing of channel resources is included within the symbols configured for uplink communication; if successful, performs a clear channel assessment, CCA, for a gap duration before the start of the indicated timing of channel resources which are to be used for the PRACH transmission; and if successful, transmits a random access, RA, preamble within the symbols configured for uplink communication at the indicated timing of channel resources which are to be used for the PRACH transmission.
