APPARATUS, AND ASSOCIATED METHOD, FOR PROVIDING A MEDIUM ACCESS CONTROL LAYER HYBRID AUTOMATIC REPEAT REQUEST SCHEME FOR A CARRIER SENSE MULTIPLE ACCESS COMMUNICATION SCHEME

摘要

Apparatus, and an associated method, for providing a hybrid automatic repeat request (H-ARQ) scheme for the Medium Access Control Layer of an IEEE 802.11n-compliant wireless local area network system, or other carrier sense multiple access communication system. When a packet delivered to a destination station is unable successfully to be decoded, a negative acknowledgement message is generated and returned to a sending station to identify the failed decoding. Selection is made at the sending station to send information, such as pursuant to a soft combining scheme or pursuant to an incremental redundancy scheme. A detector and selector embodied at the destination station detects whether the packet has been successfully delivered to the destination station and selects in what manner to respond to the sending station in response thereto.
