METHOD AND APPARATUS FOR TIME MULTIPLEXING PACKET DATA AND UPLINK CONTROL INFORMATION IN SINGLE CARRIER FREQUENCY DIVISION MULTIPLE ACCESS SYSTEM

摘要

A method and an apparatus for time-multiplexing packet data and uplink control information in an SC-FDMA(Single Carrier Frequency Division Multiple Access) system are provided to improve an uplink channel estimation using an additional pilot by providing the uplink control information and frequency hopping of the pilot. A method for time-multiplexing packet data and uplink control information in an SC-FDMA system includes the steps of: determining whether to transmit the uplink control information in transmitting uplink data(1202); time-multiplexing and transmitting the uplink data and a first pilot for the uplink data through a predetermined frequency resource when not transmitting the uplink control information(1205); and time-multiplexing and transmitting the uplink data, the first pilot for the uplink data, the uplink control information, and a second pilot for the uplink control information through the predetermined frequency resource(1208) when transmitting the uplink control information.
