ABSTRACT:
A resource division, allocation, and transmitting/receiving method of downlink for reducing inter-cell interference in an orthogonal frequency division multiplexing system are provided. Entire downlink radio resources are divided into a traffic resource group for a traffic channel and a control resource group for a control channel, the traffic resource group is divided into a first traffic resource group for the intra-cell mobile terminals and a second traffic resource group for a cell-boundary mobile terminal, and a part of the first traffic resource group is imaginarily divided into 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. The control resource group is allocated to a control channel for the intra-cell mobile terminal; and a resource of the first traffic resource group or the second traffic resource group is allocated to a traffic channel for the mobile terminal according to inter-cell interference affected to the mobile terminal. Radio resources may be reused in each downlink cell of the OFDM system, the traffic may be rapidly transmitted to the cell boundary mobile terminal, a system capacity may be increased, the cell plane may be easily performed, and the system capacity may not be decreased although the mobile terminal number, locations, and traffic density is not uniform.
