Abstract :
In this paper, different subchannelization modes for the downlink of a multi-cell OFDMA system are investigated. The frequency reuse factor is one. The subchannelization mode FUSC adopted in 802.16 is considered: frequency collision problem and partial loading are addressed. For a full loading factor, performances are compared with dynamic subcarrier allocation algorithms.
