Abstract
A communication device includes a processing unit and a transmitter. The processing unit specifies a number of data blocks in an ARQ receive window and divides the receive window into a number of sectors, each sector having a portion of the number of data blocks in the receive window. The processing unit further receives data blocks within the receive window transmitted from a transmitting communication device and constructs an acknowledgement bitmap for each sector in the receive window. The acknowledgement bitmap includes a sector acknowledgement bit. The transmitter transmits the acknowledgement bitmap for each sector to the transmitting communication device.
