Apparatus and method for transmitting feedback information using terminal accessibility in a wireless access system

A method of allocating a resource from a base station in a wireless access system, the method comprising:

• transmitting cluster information by a terminal to the base station;
• and
• transmitting channel quality indicator feedback information to the base station,
• wherein the terminal is a cluster head (CH) indicating a representative terminal among terminals included in the cluster, and
• wherein the cluster information includes channel gain information and location information for terminals belonging to the cluster including the CH.

A terminal for which a resource is allocated from a base station in a wireless access system, the terminal comprising:

• a radio frequency (RF) unit for externally transmitting and receiving an RF signal;
• and
• a controller coupled to the RF unit,
• wherein the controller controls the RF unit to transmit cluster information the base station, and controls the RF unit to transmit channel quality indicator feedback information to the base station, and
• wherein the cluster information includes channel gain information and location information for terminals belonging to a cluster including a cluster head (CH).
