US Patent 8737402 Multi-carrier scheduling

The invention provides a scheduling of data blocks on multiple data carriers and a selection of data carrier to listen to. A transmitting unit simultaneously transmits, during a communication session with at least one participating receiving unit, at least a first data block on a first data carrier and a second data block on a second data carrier. The receiving unit selects which of these data carriers to listen to, i.e. whether to receive the first or second data block, based on a reception quality of a previously received data block. Furthermore, at least one of the first and second data block is based on information common to the data block and the previous data block, e.g. the first or second data block could be re-transmitted version of the previous block.
