Patent ID: 8644283

Claim:
A femtocell base station (femto-BS), having a plurality of neighboring femto-BSs, the femto-BS and the neighboring femto-BSs belonging to a wireless network, the femto-BS comprising: a transceiver being configured to receive a frame; and a processor being electrically connected to the transceiver and being configured to perform the operations as follows: determining that the wireless network has a plurality of available network resource units according to the frame, determining an expected value that is related to the available network resource units being used by the femto-BS and the neighboring femto-BSs without having interference, the expected value being related to a number of the available network resource units and a number of the neighboring femto-BSs, calculating a plurality of strategy probability values that are related to different numbers of the available network resource units used by the femto-BS according to the expected value, and calculating an assigned number according to the strategy probability values, wherein the femto-BS is able to use the assigned number of the available network resource units.
