Improving SIR in the inter-cell area by varying re-use distances in dependence on traffic load values

摘要

The present invention relates to a method for controlling communication resources in a cellular communication network (1), the cellular communication network comprising a plurality of cells (A to Q) which are under the control of at least one base station (10) and which use the communication resources to communicate via communication links, wherein a distance between two neighboring cells of the plurality of cells using a same communication resource is defined to be a re-use distance of said same communication resource. In order to reduce inter-cell interference and thus to improve a signal to interference ratio for a user equipment in the inter-cell area, the method of aspect of the invention comprises: configuring a first setup of communication resources for a first cell (F) of said plurality of cells, and controlling the first cell to use a first set of communication resources indicated in the first setup by controlling the first cell to use a high load set of communication resources of the first set if a first load represented by a high load value is present at the first cell, and controlling the first cell to use a low load set of communication resources of the first set if a second load represented by a low load value is present at the first cell, wherein the first load is higher than the second load, and wherein the re-use distance of at least one communication resource of the low load set is larger than the re-use distance of the at least one communication resource of the high load set. Consequently the signal to interference ratio in the inter-cell area is improved by varying re-use distances of communication resources in dependence on traffic load values.
