Resource allocation apparatus, resource allocation method, and non-transitory computer readable medium

A resource allocation method for use in a resource allocation apparatus adapted for a wireless network, the wireless network comprising a femto BS, the resource allocation apparatus communicating with the femto BS and comprising a storage, a transceiver and a processor electrically connected to the storage and the transceiver, the storage storing a random function, reuse information and FFR information recording an original cell ID/frequency corresponding relation of an unoccupied partition of the wireless network, the resource allocation method comprising the steps of:

• enabling the processor to select a time partition from the unoccupied partition according to the random function and the reuse information;
• enabling the processor to change the original cell ID/frequency corresponding relation to generate a changed cell ID/frequency corresponding relation according to the FFR information, wherein the original cell ID/frequency corresponding relation is a corresponding relation between a cell ID and a frequency of a network resource;
• enabling the processor to generate an allocation message according to the time partition and the changed cell ID/frequency corresponding relation;
• and
• enabling the transceiver to convey the allocation message to the femto BS.

A resource allocation apparatus adapted for a wireless network, the wireless network comprising a femto base station (BS), the resource allocation apparatus communicating with the femto BS, comprising:

• a storage, being configured to store a random function, reuse information and fractional frequency reuse (FFR) information, the FFR information recording an original resource index of the unoccupied partition of the wireless network;
• a transceiver;
• and
• a processor, being electrically connected to the storage and the transceiver, and being configured to:
• reindex the original resource index according to the random function and the reuse information to generate a new resource index of the unoccupied partition;
• and
• generate an allocation message according to the new resource index, wherein the transceiver is configured to convey the allocation message to the femto BS.
