Patent ID: 7535858

Claim:
A method comprising: storing receive state information within a state memory for a block of frames received during a transmit opportunity (TXOP), including: comparing a transmission identifier (TID) and a transmitter address (TA) of a received data frame to a TID and a TA of the receive state information, updating the receive state information for the received data frame if the TID and TA of the receive state information match the TID and TA of the received data frame, generating additional receive state information if the TA of the received data frame matches a TA of the receive state information and the TID of the received data frame does not match the TID of the receive state information, and otherwise, discarding the receive state information, and generating new receive state information for the TID and TA of the received data frame; transmitting a block acknowledgement (ACK) including the receive state information according to a block acknowledgement request (BAR) received during the TXOP; and discarding the receive state information subsequent to completion of the TXOP.
