Patent ID: 8457057

Claim:
A method comprising: participating in an automatic repeat request (ARQ)-enabled service flow between first and second wireless stations, wherein each transmitted MAC (media access control) protocol data unit (PDU) is partitioned into one or more ARQ-blocks, with each ARQ-block, except a last ARQ block of a MAC PDU, having a fixed size equal to an ARQ-block-size; and negotiating a change to the ARQ-block-size for the service flow via a request and response message exchange, wherein the negotiating comprises: transmitting a first message including an ARQ block size change request and an ARQ feedback request for the service flow from the first wireless station to the second wireless station, the ARQ block size change request including one or more parameters relating to a new ARQ-block-size for the service flow; and receiving, at the first wireless station from the second wireless station, a second message that includes an ARQ block size change response and an ARQ feedback response for the service flow, the ARQ feedback response providing acknowledgement information for one or more transmitted ARQ blocks.
