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 ).

Claims (22)

1. 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.

2. A method for providing delayed acknowledgement in a local wireless transceiver, as recited in claim 1 , wherein the second through (n−1) th frame identifiers are media access controller protocol data unit identifiers.

3. A method for providing delayed acknowledgement in a local wireless transceiver, as recited in claim 1 , wherein the second through (n−1) th frames are fragmented frames and the second through (n−1) th frame identifiers each include fragment identifiers for their respective frame.

4. A method for providing delayed acknowledgement in a local wireless transceiver, as recited in claim 1 ,

wherein the first delayed acknowledgement response frame is sent during a first short inter-frame space during the first data frame, and

wherein the second delayed acknowledgement response frame is sent during an n th short inter-frame space during the n th data frame.

5. A method for providing delayed acknowledgement in a local wireless transceiver, as recited in claim 1 ,

wherein the first delayed acknowledgement response frame further includes first delayed acknowledgement parameters that define a first delayed acknowledgement policy, and

wherein the second delayed acknowledgement response frame further includes second delayed acknowledgement parameters that define a second delayed acknowledgement policy.

6. A method for providing delayed acknowledgement in a local wireless transceiver, as recited in claim 5 , wherein the first and second delayed acknowledgement policies are the same.

7. A method for providing delayed acknowledgement in a local wireless transceiver, as recited in claim 5 , wherein the first delayed acknowledgement parameters include at least one of: a first maximum number of allowable frames of a maximum frame size for acknowledgement in the second delayed acknowledgement response frame, and a second maximum number of allowable frames regardless of frame size that may be acknowledged in the second delayed acknowledgement response frame.

8. A method for providing delayed acknowledgement in a local wireless transceiver, as recited in claim 7 , wherein the second delayed acknowledgement parameters include at least one of: a third maximum number of allowable frames of the maximum frame size for acknowledgement in a third delayed acknowledgement response frame, and a fourth maximum number of allowable frames regardless of frame size that may be acknowledged in the third delayed acknowledgement response frame.

9. A method for providing delayed acknowledgement in a local wireless transceiver, as recited in claim 1 , wherein the method is implemented in an ultra wideband device.

10. A method for providing delayed acknowledgement in a local wireless transceiver, as recited in claim 1 , wherein the method is implemented in an integrated circuit.
