摘要:
A method for receiving multicast service data by a terminal in a communication system. The method includes receiving a pilot from a base station, measuring channel state information using the received pilot, and transmitting the channel state information to the base station; receiving a frame from the base station, and determining whether there is an error in the received frame; when no error has occurred in the received frame, determining whether the number of frames consecutively received without error is greater than or equal to a predetermined number; and when the number of frames consecutively received without error is greater than or equal to the predetermined number, transitioning to a non-feedback state where the terminal transmits no channel state information to the base station. The frame includes multicast service data.
