Method of scheduling uplink resources in cellular communication system

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;
• calculating a transmitting power Pt which is needed to be adjusted when each user equipment in the specific group of user equipments uses the sub-carrier in the corresponding group of sub-carriers;
• calculating a signal noise interference ratio of the user equipment on said group of sub-carriers based on the transmitting power Pt to be adjusted, and performing a multi-user equipment resource scheduling algorithm based on the signal noise interference power ratio.
