The present description relates to a method for performing client cooperation transmission through a group resource allocation (GRA) scheme in a wireless access system, comprising the following steps: receiving a group configuration message, including client group information, from a base station, wherein said group configuration message further includes client cooperation-enabled information that indicates whether or not the client group is concerned with the client cooperation transmission; determining whether or not to participate in the client cooperation by means of the client cooperation-enabled information; and transmitting the result of the determination on whether or not to participate in the client cooperation to the base station.

Method and apparatus for performing client cooperation transmission through a group resource allocation scheme in a wireless access system

A data transmission method in a system comprising at least one or more relays includes transmitting by a mobile station a bandwidth allocation request message to a relay, receiving by the mobile station a bandwidth allocation message from the relay, the bandwidth allocation message including information for indicating an offset from a frame where the bandwidth allocation message is contained, waiting by the mobile station for an uplink frame or uplink subframe indicated by the offset from the frame where the bandwidth allocation message is contained, and transmitting data on the indicated frame or subframe.

A method of transmitting a cell type information, which is transmitted by a base station in a wireless communication system, is disclosed. The present invention includes broadcasting a boundary point information (Z) between a cell identity of a public ABS (advanced base station) and a cell identity of a private ABS via an S-SFH SP3 (secondary-super frame header subpacket3). In this case, the boundary point information (Z) includes a range information of cell identity partitions partitioned by granularity of 10 sequences per segment and a total number of the cell identity partitions is 16.

Method for partitioning cell identities according to cell type in wireless communication system and an apparatus therefor

A method for transmitting an uplink pilot signal in a wireless communication system is disclosed. The method for transmitting an uplink pilot signal in a wireless communication system includes forming a basic unit including a plurality of pilot Resource Elements (REs) and data REs and having a size of 4 subcarriers&#xd7;9 Orthogonal Frequency Division Multiple Access (OFDMA) symbols, setting the plurality of pilot REs in the basic unit, and transmitting the basic unit to a base station. Each of the REs is time-frequency resource defined by one symbol index and one subcarrier index.
