Abstract
An OFDM communication system employs a cell time division time frame for a plurality of overlapping cells wherein the time frame comprises time slots with each time slot allocated to one of the overlapping cells and each time slot being either an information exchange time slot or a data time slot. Remote nodes (-) transmit resource requests for at least one subcarrier in a data time slot to one or more of the central nodes () in the information exchange time slots of those nodes (). The central nodes () broadcast information of uplink channel characteristics received in the request messages and the remote nodes (-) use this to determine whether to abandon or continue the resource request. Eventually, the remote node may decide to use the resource and thus to transmit in the associated data time slot. A distributed multi-cell resource allocation can be achieved based on distributed decisions in the remote stations.
