Apparatus and method for estimating carrier to interference and noise ratio in a mobile communication system based on fractional frequency reuse

摘要

An apparatus and method for estimating a carrier to interference and noise ratio (CINR) in a mobile communication system based on a fractional frequency reuse are provided. The method includes receiving a report on CINR information on a common zone from a mobile station (MS) allocated a restricted zone, calculating a received signal power value using a CINR value and an interference level value for the common zone of the MS, and estimating a CINR value for a restricted zone using the received signal power value of the MS and an interference level for the restricted zone.

1. A method in a base station (BS) for estimating a carrier to interference and noise ratio (CINR) in a mobile communication system based on a fractional frequency reuse, the method comprising:
receiving a CINR information for a common zone, a first interference level for a restricted zone, and a second interference level for the common zone from a mobile station (MS); calculating a received signal power value using the CINR information and the second interference level for the common zone of the mobile station; and estimating a CINR value for a restricted zone using the received signal power value of the mobile station and the first interference level for the restricted zone, wherein a report period of the CINR information for the common zone is different from a report period of the first interference level for the restricted zone and a report period of the second interference level for the common zone.
