Title:
無線ネットワークにおけるオポチュニスティックデータ転送及び動的再構成
Document Type and Number:
Japanese Patent JP2012503932
Kind Code:
A
Abstract:
Mobile communication devices and wireless network device each can participate in, or solely provide, opportunistic data forwarding in a wireless network such as a wireless local area network or radio access network. A supporting node receives wireless communication between a transmitting node and a receiving node comprising packet data units (PDUs). The receiving node communicates to the transmitting node that one or more portions of the communication were not received, which is overheard by the supporting node. The supporting node can have sufficient over-the-air (OTA) allocation in its transmit opportunity to relay the failed portions to the receiving node. Thereby, techniques such as more robust error encoding, longer transmit allocations, etc., that would reduce the effective data throughput for OTA resources are avoided while providing an ability to more rapidly adapt to a changing channel state.
