Abstract

A cellular communication system comprising a plurality of user equipment and a network infrastructure. Radio resource of the plurality of cells is divided into more than one radio resource groups. A network infrastructure element detects a requirement of radio resource allocation for a user equipment and determines effective interference to be generated by the required radio resource to a defined group of neighboring cells. User equipment is allocated a radio resource from one of the radio resource groups on the basis of the determined effective interference to be generated to the defined group of neighboring cells. Inter-cell interference decreases and the throughput of the cellular system increases, but the exchange of physical layer information is not increased.

First claim

That which is claimed:

1. A method, comprising:
utilizing, in a cell, a radio resource formed from a plurality of radio resource units, wherein a radio resource unit corresponds to a separable unit in at least one of time or frequency domains and consists of one or more subcarriers within a timeslot, and wherein the radio resource unit includes one or more of a carrier frequency, a timeslot or a spread spectrum code;
dividing the radio resource units of a plurality of cells into…
