Abstract

In some examples, a device aggregates data frames into an aggregated data frame for communication in an Outside the Context of a Basic Service Set (OCB) mode.

Claims (32)

1. A method comprising:

aggregating, by a first device, a plurality of data frames into an aggregated data frame for communication in an Outside the Context of a Basic Service Set (OCB) mode;

transmitting, from the first device to a second device, an information element set to a value to provide capability information to the second device indicating support by the first device for aggregation of data frames in the OCB mode;

transmitting, from the first device to the second device, a management or control frame with an indicator of an acknowledged mode for the OCB mode to cause operation in the acknowledged mode for the OCB mode; and

transmitting, by the first device to the second device, the aggregated data frame in the OCB mode and in the acknowledged mode.

2. The method of claim 1 , wherein aggregating the plurality of data frames comprises removing Medium Access Control (MAC) headers of the plurality of data frames and aggregating remaining portions of the plurality of data frames without the MAC headers into the aggregated data frame.

3. The method of claim 2 , wherein the aggregated data frame is an Aggregate MAC Service Data Unit (A-MSDU).

4. The method of claim 1 , wherein aggregating the plurality of data frames comprises aggregating the plurality of data frames with Medium Access Control (MAC) headers into the aggregated data frame.

5. The method of claim 4 , wherein the aggregated data frame is an Aggregate MAC Protocol Data Unit (A-MPDU).

6. The method of claim 1 , wherein the information element is included in a header of the aggregated data frame.

7. The method of claim 1 , further comprising:

receiving a further aggregated data frame;

in response to detecting an information element in the further aggregated data frame specifying that the further aggregated data frame includes an aggregation of data frames in the OCB mode:

apply a rule to decode the further aggregated data frame.

8. The method of claim 7 , further comprising:

determining whether to transmit an acknowledgment of the further aggregated data frame based on the rule.

9. The method of claim 1 , wherein the first device is a wireless device, the method further comprising:

sending, from a first protocol layer of the wireless device to a second protocol layer of the wireless device, an indication of a capability relating to support for aggregation of data frames in the OCB mode.

10. The method of claim 9 , wherein the second protocol layer is a Wave Short Message Protocol (WSMP) layer, and the first protocol layer is a Medium Access Control (MAC) layer.

11. A first wireless device comprising:

a hardware processor to provide data frames for communication to a second wireless device; and

a protocol layer to:

aggregate the data frames into an aggregated data frame for communication in an Outside the Context of a Basic Service Set (OCB) mode,

transmit, from the first wireless device to the second wireless device, an information element set to a value to provide capability information to the second wireless device indicating support by the first wireless device for aggregation of data frames in the OCB mode,

transmit, from the first wireless device to the second wireless device, a management or control frame with an indicator of an acknowledged mode for the OCB mode to cause operation in the acknowledged mode for the OCB mode, and

transmit, from the first wireless device to the second wireless device, the aggregated data frame in the OCB mode and in the acknowledged mode.

12. The first wireless device of claim 11 , wherein the management or control frame is an action frame.

13. A non-transitory machine-readable storage medium comprising instructions that upon execution cause a first wireless device to:

aggregate data frames into an aggregated data frame for communication in an Outside the Context of a Basic Service Set (OCB) mode;

transmit, from the first wireless device to a second wireless device, an information element set to a value providing capability information to the second wireless device indicating support by the first wireless device for aggregation of data frames in the OCB mode;

transmit, from the first wireless device to the second wireless device, a management or control frame with an indicator of an acknowledged mode for the OCB mode to cause operation in the acknowledged mode for the OCB mode; and

transmit, from the first wireless device to the second wireless device, the aggregated data frame in the OCB mode and in the acknowledged mode.
