20100246538 | ADAPTIVE FREQUENCY REUSE METHOD OF RADIO RESOURCES MANAGEMENT AND ALLOCATION - A method for managing and allocating radio resources (RRMA method) of multiple radio resource types to subscriber stations is disclosed. The RRMA method includes bandwidth partitioning, into parts comprising “slots” with a given reuse pattern, a selection rule, to select a “cell, reuse pattern” pair serving each user, and an allocation rule, for distributing to each user an appropriate number of bandwidth slots from the selected “cell, reuse pattern” pair.

Particularly, the method is applicable in fractional frequency reuse cellular networks. | 09-30-2010 |
