METHOD AND APPARATUS FOR DYNAMIC INTER-CELL INTERFERENCE AVOIDANCE IN CELLULAR COMMUNICATION NETWORKS
First Claim
Patent Images
1. A method, comprising:
- classifying users in each of adjacent cells in a cellular communication network into cell edge users and cell centre users;
determining allocation priorities for each of the adjacent cells;
allocating resources to the users in each of the adjacent cells based on the allocation priorities, except that resources allocated to cell edge users in one of the adjacent cells are restricted from use by other adjacent cells having lower allocation priorities to thereby inhibit inter-cell interference among the adjacent cells.

10. An apparatus, comprising:
-
a processor; a memory coupled to the processor; and instructions stored in the memory that, when executed by the processor, cause the processor to; classify users in each of adjacent cells in a cellular communication network into cell-edge users and cell-centre users; determine allocation priorities for each of the adjacent cells; allocate resources to the users in each of the adjacent cells based on the allocation priorities, except that resources allocated to cell-edge users in one of the adjacent cells are restricted from use by other adjacent cells having lower allocation priorities to thereby inhibit inter-cell interference among the adjacent cells. - View Dependent Claims (11, 12, 13)
