Abstract
A transmit power control method of a terminal in direct communication between terminals is disclosed. The terminal measures a path loss gain of a base station, and compares the measured path loss gain with a predetermined threshold value. The terminal sets a power value for direct communication in the case in which the measured path loss gain is less than or equal to the predetermined threshold value, and performs the direct communication at the set power value.
Claims14
A method of setting transmit power by a first terminal performing direct communication with a counterpart terminal, the method comprising:
- measuring a first channel gain which is a path loss gain between a base station to which the first terminal belongs and the first terminal;
- comparing the first channel gain with a predetermined threshold value;
- setting a first power value for the direct communication in the case in which the first channel gain is less than or equal to the threshold value;
- and
- performing the direct communication at the first power value.
A terminal comprising:
- a radio frequency (RF) module receiving a reference signal from a base station;
- and
- a processor measuring a first channel gain which is a path loss gain with the base station using the reference signal and controlling direct communication with a counterpart terminal,
- wherein the processor includes a power setting module comparing the first channel gain with a predetermined threshold value and setting a first power value for the direct communication in the case in which the first channel gain is less than or equal to the threshold value.
