Method and frame structure for supporting dynamic channel allocation and dynamic power allocation in frequency reuse partitioning based OFDMA system

摘要

Provided are a dynamic channel/power allocation method for an FRP-based OFDMA system and a frame/slot structure capable of supporting the dynamic channel/power allocation method. In the FRP-based OFDMA system, each of cells has an inner cell, an outer cell and a plurality of sectors and performs data communication with a plurality of MSs therein through one or more orthogonal subchannel groups. In the dynamic channel/power allocation method, a BS receives a feedback channel condition from an MS provided with a service of the BS and allocates a subchannel group with a high SINR to each MS in consideration of the fairness and the distance information of each MS. Power is allocated to each MS on the basis of the conditions of a channel allocated to each MS, thereby obtaining a multi-user diversity gain.
