  • Patent number: 10039062
    Abstract: A method for controlling, by a base station, uplink transmission power of a mobile terminal. The base station receives an available transmission power amount of the mobile terminal from the mobile terminal. The base station determines a target channel quality value corresponding to a current location of the mobile terminal, on the basis of the available transmission power amount. The base station determines a received channel quality value using an uplink data channel received from the mobile terminal. Further, the base station determines a transmit power control (TPC) using a difference between the target channel quality value and the received channel quality value.

  • Publication number: 20160113019
    Abstract: A second terminal which performs direct communication with a first terminal receives a signal for measuring a radio channel from the first terminal and calculates radio channel quality. Further, the second terminal calculates a data error rate using replay information indicating whether data are received and compensates for the radio channel quality depending on a data error rate. The second terminal reports the compensated radio channel quality to a base station and the base station uses the compensated radio channel quality to allocate resources used in direct communication.
