UPLINK TRANSMISSION CONTROL METHOD IN A WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREOF CAPABLE OF CONTROLLING SOUNDING REFERENCE SIGNAL TRANSMISSION POWER FROM A MACRO TERMINAL

摘要

PURPOSE: An uplink transmission control method in a wireless communication system and apparatus are provided to reduce interference generated between heterogeneous networks.;CONSTITUTION: A micro base station creates information for wireless resources used for the uplink scheduling of a micro UE(User Equipment)(S21). The micro base station transmits micro UE scheduling wireless resource information to terminals within a service area(S22). A micro UE sets SRS(Sound Reference Signal) transmission power as zero by controlling the transmission power of an SRS for the wireless resources which are able to generate inter-cell interference(S23). A macro base station reduces the uplink transmission power of the macro terminal in the uplink wireless resources by avoiding the uplink wireless resources(S24).;COPYRIGHT KIPO 2013
