FIELD: physics.
SUBSTANCE: invention relates to wireless communication LAA (license access). User equipment comprises a receiver operable to receive UL (uplink) permission, which schedules subframe for UL transmission; a first circuit operable to perform LBT (listening before transmission); a transmitter operable to transmit PUSCH in a scheduled subframe starting from one available initial position from multiple potential initial positions in a scheduled subframe if the LBT is successful.
EFFECT: technical result consists in enabling possibility to increase probability that PUSCH may be sent in planned subframe after LBT.
