Method and apparatus for managing radio resource in wireless communication system

A method for allocating transmission power of at least one access point (AP) in a wireless communication network, the method comprising:

• determining first transmission power meeting a cell outer condition between the AP and APs selected among a plurality of APs;
• and
• determining second transmission power smaller than the first transmission power and meeting a cell inner condition of the AP, wherein the cell outer condition comprises a case where signal strength between the AP and at least one external neighbor cell is less than a first threshold determined in advance, wherein the cell inner condition comprises a case where signal strength between the AP and at least one internal station belonging to the AP is greater than a second threshold determined in advance, and wherein the second threshold has a value less than the first threshold, and is adaptively set based on traffic information used for communication between the AP and the internal station.

An apparatus for allocating transmission power of at least one access point (AP) in a wireless communication network, the apparatus comprising:

• an information collector configured to collect information regarding signal strength between the AP and at least one external neighbor cell, and signal strength between the AP and at least one internal station belonging to the AP;
• and
• a resource manager configured to determine first transmission power meeting a cell outer condition between the AP and APs selected among a plurality of APs, and determine second transmission power smaller than the first transmission power and meeting a cell inner condition of the AP, wherein the cell outer condition comprises a case where signal strength between the AP and at least one external neighbor cell is less than a first threshold determined in advance, wherein the cell inner condition comprises a case where signal strength between the AP and at least one internal station belonging to the AP is greater than a second threshold determined in advance, and wherein the second threshold has a value less than the first threshold, and is adaptively set based on traffic information used for communication between the AP and the internal station.
