Patent ID: 8068785

Claim:
A resource division and allocation method for reducing an inter-cell interference of a downlink transmitted from a base station to an intra-cell mobile terminal in an orthogonal frequency division multiplexing (OFDM) cellular system, the resource division and allocation method comprising: (a) dividing entire downlink radio resources into a traffic resource group for a traffic channel and a control resource group for a control channel; (b) dividing the traffic resource group into a first traffic resource group for the intra-cell mobile terminals and a second traffic resource group for cell-boundary mobile terminals; (c) imaginarily dividing a part of the first traffic resource group as a (1−1)-th preliminary traffic resource group, the (1−1)-th preliminary traffic resource group being a preliminary resource group for the cell-boundary mobile terminal; (d) allocating the control resource group as a control channel for the intra-cell mobile terminal; and (e) allocating a resource of the first traffic resource group or the second traffic resource group as a traffic channel for the mobile terminal according to inter-cell interference affecting the mobile terminal.
