发明名称 APPARATUS, METHOD AND COMPUTER PROGRAM PRODUCT PROVIDING SUB-CHANNEL ASSIGNMENT FOR RELAY NODE
摘要 Disclosed herein are apparatus, methods and computer program products providing sub-channel re-assignment performed by a relay node in a wireless communications system. In the apparatus, methods and computer program products, a relay receives an input signal made up of a plurality of sub-channels. The relay de-multiplexes the sub-channels into a plurality of signal streams, and reassigns at least one of the signal streams to a new sub-channel on the output side, the new sub-channel on the output side different from the sub-channel originally containing the signal stream on the input side. In one embodiment of the invention, the wireless communications system is an OFDM system and the sub-channels correspond to OFDM sub-carriers. In another embodiment of the invention, during sub-channel reassignment input sub-channels are matched to output sub-channels sharing a pre-determined criterion.
