ABSTRACT:
A re-transmit processor for a wireless communication system includes a pointer memory which contains pointers associated with particular packet data in a host memory. The re-transmit processor directs data associated with said pointers to be applied to a media access controller, which optionally contains an encryption function, the output of which is coupled to a block buffer and to an output interface. Upon receipt of a transmission request, the host memory locations associated with the pointers are read and the data directed to the media access controller, which adds a header, a CRC, and optionally encrypts the data, thereafter placing it in the block buffer and the output interface. Upon provision of the packet data to the MAC, the associated pointer is initialized to a FREE or UNUSED value, and upon receipt of an acknowledgement of the packet accompanied by a packet identifier from a receiving station, the packet associated with the packet identifier is removed from the block buffer.
