Claim Text:
1. A user equipment terminal, comprising: a first power control module configured to control a first transmission power to be applied to at least one signal used for communication between the user equipment terminal and a base station, wherein the first transmission power is determined based on at least one first power control parameter received from the base station; a second power control module configured to control a second transmission power to be applied to at least one signal used for device-to-device services, wherein the second power control module is configured to determine the second transmission power from the minimum of (i) a maximum power for the at least one signal used for device-to-device services and (ii) a transmission power based on a frequency bandwidth for the at least one signal used for device-to-device services, wherein the user equipment terminal is configured to determine the maximum power based on at least one second power control parameter received from the base station; and a signal transceiver module configured to transmit the at least one signal used for communication between the user equipment terminal and the base station using the first transmission power and to transmit the at least one signal used for device-to-device services using the second transmission power.
