Abstract:
1. A method of controlling uplink transmission by a user equipment in a wireless communication system, the method comprising: configuring a transmission mode for a PUSCH (Physical Uplink Shared Channel) as one of a SU-MIMO (Single User Multiple Input Multiple Output) mode and a Non-SU-MIMO mode; and performing a procedure for UCI (Uplink Control Information) transmission at a subframe, wherein the UCI needs to be transmitted at the subframe, wherein, if the SU MIMO mode is configured and if there is allocation of a PUSCH at the subframe, transmission of the UCI is dropped at the subframe, and wherein, if the Non-SU-MIMO mode is configured and if there is allocation of a PUSCH at the subframe, the UCI is transmitted via the PUSCH at the subframe.
