TRANSMISSION FRAME AND RESOURCE ALLOCATION METHOD FOR COMMUNICATION SYSTEM INCLUDING BASE STATIONS
First Claim
1. A communication apparatus configured to perform a communication according to a transmission frame, wherein a downlink subframe of the transmission frame comprises:
- a downlink coordination zone where a plurality of femto base stations performs a 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 performs the downlink communication with particular terminals among the plurality of terminals using a shared radio resource.
