US Patent 10979985 Terminal and relay devices, base station and methods

A relay device configured to communicate with a terminal device of the network and with a base station of the network. The relay device comprises transmitter circuitry, receiver circuitry and controller circuitry. The controller circuitry is configured in combination with at least the transmitter circuitry: to select a maximum transmission power to be used by the terminal device for communicating with the relay device, wherein the identified maximum transmission power is based on link information relating to one or both of the link between the relay device and the base station and the link between the relay device and the terminal; to notify the communication device of the selected maximum transmission power for the terminal to select an actual transmission power and to transmit signals to the relay device at a power that is no more than the maximum transmission power.
