Abstract
A method of scheduling resources in an uplink of a wireless cellular communication system, comprising the steps of measuring, by each user equipment in a present cell, pilot strengths of adjacent cells to find base stations within adjacent cells on which the user equipment has the strongest inter-cell interferences and to calculate values of the inter-cell interferences in an uplink direction which is caused by the user equipment on said base stations within said adjacent cells; grouping all user equipments within the present cell based on the calculated values of the inter-cell interferences; grouping used sub-carriers based on the groups of the user equipments so that each group of user equipments corresponds to one group of sub-carriers; allocating each group of sub-carriers to the user equipments included in the group of user equipments selected corresponding to the group of sub-carriers; and based on the allocation of the group of the sub-carriers, calculating a modified signal noise interference power ratio of each user equipment on the corresponding group of sub-carriers, and performing a multi-user equipment resource scheduling algorithm.
