DIRECT CONNECTION COMMUNICATION BETWEEN TERMINALS AND DIRECT DATA TRANSMITTING/RECEIVING METHOD FOR A TERMINAL RELAY CAPABLE OF REDUCING THE WASTE OF WIRELESS RESOURCE

摘要

PURPOSE: A direct connection communication between terminals and direct data transmitting/receiving method for a terminal relay are provided to perform the transmission and reception of data between terminals without passing through a base station.;CONSTITUTION: A receiver changes a receiving frequency into an uplink frequency(S220). A transmitter changes a transmitting frequency to a downlink frequency. The receiver receives data from the other terminal(S230). The transmitter transmits data to the other terminal.
