Abstract
A method of providing an automatic repeat request (ARQ) that employs a selective repeat, enabling a transmitting medium access control (MAC) entity at a transmitting station to retransmit those MAC data whose previous transmissions have failed is described. The MAC data is organized into fixed-sized ARQ blocks, with said ARQ blocks being the building blocks of MAC service data units (MSDUs) or MSDU fragments; The transmitting MAC entity assigns a local number and a global number to each ARQ block to be transmitted and identifies ARQ blocks contained in a transmitted MAC protocol data unit (MPDU) by including into the MPDU the local and global numbers of the first ARQ block in that MPDU. A receiving MAC entity at a receiving station determines and acknowledges the reception status of the ARQ blocks received or anticipated.
