Claim 0:
1. A first wireless device, comprising:
a receiver, which, in operation, receives from a second wireless device power control information, the power control information including a first transmission power of the second wireless device; and
a transmitter, which, in operation, transmits to a third wireless device a data by using a second transmission power,
wherein, in a first defined case, the second transmission power is determined by a first power control scheme, which is based at least on a transmission path loss between the first wireless device and the second wireless device,
wherein the transmission path loss is determined based at least on a reference signal transmission power and a reference signal received power (RSRP),
wherein, in a second defined case, the second transmission power is determined by a second power control scheme without using the transmission path loss between the first wireless device and the second wireless device,
wherein one of the first defined case or the second defined case is configured by a higher layer signaling, and
wherein the transmitter, in operation, transmits to the third wireless device control information by using a third transmission power, which is determined by adding an offset value to the second transmission power.
