Abstract
A user grouping method for inter-cell interference coordination technology in mobile telecommunication systems using the handover information and measured data that were defined in existing mobile telecommunication systems to group cell users into cell center users and cell edge users. This method includes: (1) user equipment measuring the average signal strength of the serving cell and neighboring cells; (2) user equipment determining if it should reply with the average signal strength information it measures and if it should initiate the inter-cell interference coordination measuring and response system; (3) serving cell then groups the user equipment as cell center user or cell edge user according to the average signal strength information reported by the user equipment; (4) serving cell allocates a frequency subchannel from cell center subband or cell edge subband according to the grouping result.
