Resource allocation method for downlink transmission in a multicarrier-based CDMA communication system
First Claim
1. A resource allocation method in a communication system supporting multiple access of a plurality of terminals identified using spreading codes, the method comprising:
- collecting, from terminals located in a service area of a base station, information of respective received signal strengths of the terminals for channels;
determining whether a terminal having a received signal strength higher than a predetermined threshold for a specific subchannel is present; and
allocating the specific subchannel to at least one terminal as a function of the determination.

Abstract
In a resource allocation method in a multicarrier-based mobile communication system that includes base stations and supports multiple access of a plurality of terminals identified using codes, the service area of each base station is divided into at least two virtual cells having different radii about the base station, and resources are actively allocated to terminals located in the service area according to distribution of the terminals in the virtual cells. The service area is divided into two virtual cells based on the received signal strengths of the terminals for a specific subchannel, and the specific subchannel is allocated to one terminal or at most two terminals according to distribution of the terminals in the virtual cells.
