Method and apparatus for transceiving data in a wireless access system

摘要

The present invention relates to a method which involves determining a relay terminal in an M2M communication system, and transceiving data to/from a base station or other terminal through the determined relay terminal, and to a method for constructing frames for transceiving data in the M2M communication system. By means of the data-transceiving method, an M2M terminal can transmit/receive a signal to/from a base station or other M2M terminal, and frames of a base station and M2M terminal can be efficiently constructed, wherein said method includes: receiving, by a first terminal of a wireless access system, a first message including a relay operation parameter, which is information that indicates a transmitting or receiving operation, from a base station during a downlink section and/or uplink section within a frame; and transceiving, by the first terminal, data to/from the base station or other terminal on the basis of the received relay operation parameter.

1. A method for performing a relay operation by a terminal in a wireless access system, the method comprising:
receiving a relay operation trigger signal from a base station, the relay operation trigger signal used for requesting terminals within a cell of the base station to provide the base station with information which is to be used by the base station to determine, among the terminals, a relay terminal that will perform the relay operation; transmitting a response signal to the base station, the response signal including the information requested by the base station, the information used by the base station to determine, among the terminals, the relay terminal that will perform the relay operation; receiving a first message including an indicator which instructs the terminal to perform the relay operation and a relay operation parameter from the base station; and performing the relay operation between the base station and a second terminal based on the received relay operation parameter, wherein the relay operation parameter is information that indicates a transmitting operation or a receiving operation in at least one of a downlink section and an uplink section in a frame, wherein the first message further includes switching period information that indicates switching of the transmitting operation or receiving operation determined by the relay operation parameter on a frame-by-frame basis or superframe-by-superframe basis, wherein the relay operation parameter indicates a receiving operation to receive data from the base station in a downlink section of a first frame, and the transmitting operation to transmit the data received in the downlink section of the first frame to the second terminal in a downlink section of a second frame, and wherein the downlink section is divided into a downlink access zone and a downlink relay zone, and a signal to be transmitted to the second terminal is received through the downlink relay zone.
