Abstract
Communication apparatuses and a transmission frame having a downlink subframe are provided. The downlink subframe of the transmission frame may include a downlink coordination zone where a plurality of femto base stations may perform the downlink communication with at least one terminal among a plurality of terminals using a different radio resource, and a downlink shared zone where the plurality of femto base stations may perform the downlink communication with particular terminals among the plurality of terminals using a shared radio resource. The transmission frame may further include an uplink subframe that includes an uplink coordination zone and an uplink shared zone.
