1. A user equipment, comprising:
a receiver, which, in operation, receives indication information of power control for a transmission of a sidelink channel, the indication information indicating that (i) in a first case, a sidelink reference signal is used for a determination of pathloss used for the power control of the sidelink channel, and (ii) in a second case, a downlink reference signal is used for the determination of the pathloss; and
circuitry, which, in operation, determines the pathloss based on the sidelink reference signal in the first case, and determines the pathloss based on a single downlink reference signal determined from a plurality of downlink reference signals in the second case, the plurality of downlink reference signals associated with a plurality of beams,
wherein a parameter P0 and a parameter alpha, which are used for the power control of the sidelink channel, are common between the plurality of beams.
