UPLINK TRANSMISSION IN CARRIER AGGREGATION ENVIRONMENT

摘要

PURPOSE: Upper line transfer electricity in carrier wave collection environment is provided to perform the efficient transmission of upper line transfer in a wireless telecommunications system. CONSTITUTION: A base station monitors the location of a terminal UE(User Equipment) in a cell(S1010). Based on various information, the base station selects an uplink transfer mode from a plurality of uplink transmission mode UL(UpLink) transmission mode(S1020). The base station transmits the information directing a selected UL transmission mode to the terminal(S1030). The base station receives a signal in consideration of the uplink transfer mode of the terminal from the terminal(S1040).
