UPLINK SIGNAL TRANSMITTING/RECEIVING METHOD IN A WIRELESS COMMUNICATIONS SYSTEM, CAPABLE OF IMPROVING THE ACCURACY OF UPLINK POWER CONTROL BASED ON THE AMOUNT OF PREDICTED INTERFERENCE, AND A DEVICE THEREOF

摘要

PURPOSE: An uplink signal transmitting/receiving method in a wireless communications system and a device thereof are provided to enable a mobile terminal to transmit signals by controlling uplink transmission power based on adjacent reception beam allocation information, etc. CONSTITUTION: A reception part (904) receives a power control variable, which is determined based on an interference value against a first reception beam among multiple reception beams of a base station, and adjacent reception beam allocation information from the base station. The adjacent reception beam allocation information shows whether reception beams except the first reception beam among the multiple reception beams are used for the reception of uplink signals. A control part (900) determines an uplink transmission power value based on the received power control variable and adjacent reception beam allocation information. A transmission part (902) transmits uplink signals to the base station by using the determined uplink transmission power value.
