ABSTRACT:
A method (1200) is provided for allowing delayed acknowledgement in a local wireless transceiver. In this method the local transceiver (324) receives n data frames (1000) from a remote wireless transceiver (322), each data frame (1000) including a set of acknowledgement policy bits, which indicate a desired acknowledgement policy for the respective data frame (1000). The first (n—1) data frames (811-814) indicate an acknowledgement policy of delayed acknowledgement with no acknowledgement requested, while the final data frame (815) indicates an acknowledgement policy of delayed acknowledgement with acknowledgement requested. In response to the acknowledgement policy of the last data frame (815), the local transceiver (324) sends a delayed acknowledgement response frame (1135) to the remote wireless transceiver (322). This delayed acknowledgement response frame (1135) includes frame identifiers for the first (n−1) data frames (811-814), but does not include a frame identifier for the last data frame (815).
