Method and device for performing terminal-to-terminal cooperative communication in wireless access system

摘要

The present invention provides a method for a source terminal performing client cooperation in a wireless access system, and the method includes: receiving, from a base station, first control information for performing client cooperation, wherein the first control information contains resource area information that is allocated for channel state measurement between a source terminal and a cooperative terminal and a control signal that is used for the channel state measurement; measuring a channel state with the cooperative terminal by using the resource area information and the control signal; receiving, from the base station, second control information for performing client cooperation with the cooperative terminal; and performing client cooperation by using the second control information, wherein the first control information further contains frame structure information for defining an operation for the source terminal and the cooperative terminal performing client cooperation in a client cooperation frame.

1. A method of performing cooperation communication between mobile stations in a wireless access system, the method performed by a source mobile station (MS) and comprising:
receiving first control information for the cooperation communication from a base station (BS), the first control information including resource region information allocated for a channel state measurement between the source MS and a cooperative MS and information related to a control signal for the channel state measurement; measuring a channel state with the cooperative MS based on the resource region information and the control signal; transmitting data to the cooperative MS, the data for transmission by the cooperative MS to the BS based on the cooperative communication; receiving second control information from the BS for the cooperation communication with the cooperative MS, the second control information including resource allocation information for data transmission based on the cooperative communication; and performing the cooperation communication based on the second control information, wherein the resource region information includes information related to at least one uplink subframe transmitted by each of the source MS and cooperative MS for a sounding signal for the channel state measurement, wherein the first control information further includes frame structure information defining an on/off operation for each of the source MS and cooperative MS during the cooperation communication, wherein the frame structure information includes first information and second information, wherein the first information is related to a first on/off operation of the source MS on a time resource corresponding to each subframe included in at least one frame for the cooperation communication, wherein the second information is related to a second on/off operation of the cooperative MS on the time resource, wherein the source MS and the cooperative MS do not have a same on/off operation pattern.
