摘要： In a communications device a grouping unit uses channel state information when mapping data bits to a plurality of different constellation groups. Each constellation group is assigned to another modulation scheme. A plurality of sub-carriers is assigned to none or one of the constellation groups and each modulation uses another one of the constellation groups. The communications device includes at least one scalable interleaver unit, wherein each interleaver unit is assigned to one of the constellation groups and interleaves the assignment of data bits mapped to each constellation group and the sub-carriers that carry a symbol information derived from the data bits. As an example, the interleaver unit performs frequency interleaving by interleaving, at constellation level, the sub-carriers that carry the symbol information.

摘要： A first wireless ad hoc network with a certain available amount of bandwidth comprises a plurality of wireless terminals communicating via wireless connections with each other. Each wireless connection requires a certain amount of the available amount of bandwidth. A problem occurs, if a wireless terminal wants to set up a new wireless connection requiring bandwidth or requires more bandwidth for an existing wireless connection and the required amount of bandwidth exceeds the left amount of the available amount of bandwidth of the first wireless ad hoc network. In a state of the art wireless ad hoc network the requested bandwidth cannot be provided and a user application may not be possible. According to the invention, however, the required amount of bandwidth can be provided by splitting the first wireless ad hoc network such that a second wireless ad hoc network is spawned which operates in a different communication channel and thus provides additional bandwidth. The second wireless ad hoc network comprises wireless terminals of the first wireless ad hoc network and/or new wireless terminals.
