Apparatus for resource allocation in a frequency overlay system and a method thereof

摘要

A resource allocation method and apparatus for a frequency overlay system that is capable of reducing the overhead of the resource allocation information transmitted by the base station is provided. A frequency overlay system of the present invention includes a base station which transmits resource allocation information including an address type selected among multiple address types designating addresses for transmission resource in different patterns and an address value indicating a resource region allocated according to the selected address type and at least one mobile station which receives the resource allocation information and receives data through the resource region identified with reference to the resource type and address value indicated by the resource allocation information; and a resource allocation method of the present invention includes transmitting, at a base station, resource allocation information including an address type selected among multiple address types designating addresses for transmission resource in different patterns and an address value indicating a resource region allocated according to the selected address type, and receiving, at a mobile station, data through the resource region identified with reference to the resource type and address value indicated by the resource allocation information.

主权项

1. A base station for a frequency overlay system in which available frequency bandwidth is divided into a plurality of frequency bands, comprising:
a controller configured to control selecting an address type to be used for allocating transmission resource to one of mobile stations connected to the base station according to supportable Frequency Assignments (FAs) of the mobile station, the address type indicating, for the mobile station connected to the base station, an order to designate addresses for resource blocks of the transmission resource of the base station, to control allocating resources to transmit data, and to control generating a MAP message including resource allocation information including the address type selected by the address type selector and an address value indicating a resource region allocated according to the address type; and a transmitter configured to transmit the MAP message through a primary FA of the mobile station.
