ABSTRACT:
An apparatus and method for block acknowledgements with reduced recipient state information are described. In one embodiment, the method comprises the storing of a receive state for a block of frames received during a transmission opportunity (TXOP) with an on-chip state memory. Once stored, an immediate block acknowledgement, including the receive state information, may be transmitted to an originator according to a block acknowledgement request (BAR) received during the TXOP. In the embodiments described, the BAR is received during the TXOP in which the block of data frames were transmitted to a recipient. In one embodiment, the recipient is free to discard the receive state information to free space within the on-chip system memory by requiring the originator to maintain the receive state information of blocks of data frames transmitted during TXOPs. Other embodiments are described and claimed.
