Patent ID: 7304975

Claim:
A method for providing delayed acknowledgement in a local wireless transceiver, comprising: receiving a first data frame from a remote wireless transceiver, the first data frame including a first set of acknowledgement policy bits, which indicate that the first data frame has a first desired acknowledgment policy of delayed acknowledgement with acknowledgement requested; sending a first delayed acknowledgement response frame to the remote wireless transceiver after receiving the first data frame; receiving second through (n−1) th data frames from a remote wireless transceiver, the second through (n−1) th data frames including second through (n−1) th acknowledgement policy bits, respectively, which indicate that the second through (n−1) th data frames have second through (n−1) th desired acknowledgement policies of delayed acknowledgement with no acknowledgement requested; receiving an n th data frame from a remote wireless transceiver, the n th data frame including an n th set of acknowledgement policy bits, which indicate that the n th data frame has an n th desired acknowledgement policy of delayed acknowledgement with acknowledgement requested; and sending a second delayed acknowledgement response frame to the remote wireless transceiver after receiving the n th data frame, wherein the first delayed acknowledgement response frame does not include a first frame identifier identifying the first data frame, wherein the second delayed acknowledgement response frame includes second through (n−1) th frame identifiers, identifying the second through (n−1) th data frames, respectively, and wherein the second delayed acknowledgement response frame does not include an n th frame identifier identifying the n th data frame.
