Ue behavior for multi-antenna transmission

PURPOSE: A terminal action for multi-antenna transmission is provided to execute uplink transmission through a multi-antenna. CONSTITUTION: A base station determines a multi-antenna transmission mode of a terminal(S2110). The base station allocates at least one PUCCH(Physical Uplink Control Channel) resource to the terminal(S2120). The terminal sets a multi-antenna transmission mode based on the number of allocated PUCCH resources(S2130). The terminal transmits an uplink signal to the base station through a multi-antenna according to the set multi-antenna transmission mode(S2140).
