Abstract:
To efficiently control a cell by using a non-allocated frequency band or a shared frequency band. The terminal device includes a reception unit configured to receive a PDCCH, a transmission unit configured to transmit a PUSCH in a serving cell, and a CCA check unit configured to perform either first LBT for performing a CCA check a number of times based on a random number before a subframe for which a transmission of the PUSCH is indicated or second LBT for performing a CCA check only once. The terminal device switches between the first LBT and the second LBT, based on a prescribed condition.

Claim (Index 12):
A method for a terminal device, the method comprising:\n receiving a physical downlink control channel including a downlink control information (DCI) format; transmitting a physical uplink shared channel (PUSCH) for a licensed assisted access cell scheduled by the DCI format; and performing a listen before talk (LBT) procedure, the LBT procedure being a procedure that senses a channel to determine whether the channel is idle or busy before transmission of the PUSCH, wherein the performing is configured to perform either one of a first type of the LBT procedure for a first duration and a second type of the LBT procedure according to a value in a predefined field of the DCI format, the first duration is denoted by a number of clear channel assessment (CCA) checks that is obtained by a random number, and the second duration is a predefined duration of one CCA check.
