Patent ID: 8243670

Claim:
A user grouping method for inter-cell interference coordination technology in mobile telecommunication systems that has the following steps: a. measuring, by user equipment (UE), an average signal strength of each of a serving cell and neighboring cells; b. identifying a neighboring cell of the neighboring cells having an average signal strength greater than the remaining neighboring cells; c. evaluating whether a difference between the average signal strength of the serving cell and the neighboring cell having the greatest average signal strength is less than a threshold value to determine if the UE is to reply with the average signal strength information measured by the UE and if the UE is to initiate an inter-cell interference coordination (ICIC) measuring and response system; d. grouping the user equipment as cell center user or cell edge user by the serving cell according to the average signal strength information reported by the user equipment; and e. allocating a frequency subchannel according to the grouping result by the serving cell.
