Apparatus and method for transmitting and receiving control information in a broadband wireless communication system using half frequency division duplex

摘要

An apparatus and method for transmitting/receiving control information in a broadband wireless communication system using Half Frequency Division Duplex (H-FDD) are provided. An operation of a Mobile Station (MS) includes, in the case of a frame at which control information is not transmitted, performing uplink communication at a front end of the frame and, in the case of a frame at which the control information is transmitted, performing downlink communication at a front end of the frame.

1. A method for receiving control information by a mobile station (MS) operating in a transmission mode at a front end of a frame in a wireless communication system using half frequency division duplex (H-FDD), the method comprising:
transmitting first uplink data at a front end of a first frame that does not include a control channel for transmitting control information; receiving a first part of the control information through a last downlink sub-frame of the first frame; receiving a second part of the control information at a front end of a second frame that includes the control channel; and changing into a transmission mode from a reception mode during an interval not occupied by the second part in a first sub-frame of the second frame, wherein a first interval for transmitting the first uplink data in the first frame and a second interval for transmitting second uplink data in the second frame are different in a length.
