Systems and methods for variable length block acknowledgment

A wireless node for wireless communication, comprising:

• at least one antenna;
• an interface configured to receive an indication of block acknowledgment (BA) parameters, wherein the indication of the BA parameters indicates a buffer size;
• a processing system configured to:
• determine a size of a bitmap field based at least in part on the indication of the BA parameters including the buffer size,
• generate a BA frame comprising the bitmap field, a type field indicating a type of the BA frame, and an indication of the determined size of the bitmap field, wherein the bitmap field acknowledges a number of packets associated with at least two traffic identifiers (TIDs) correctly received by the apparatus and the determined size of the bitmap field is associated with the type field indicating a type of the BA frame;
• and
• wherein the interface is further configured to output the BA frame for transmission to another wireless node via the at least one antenna.

A method of wireless communication by an apparatus, comprising:

• receiving an indication of block acknowledgment (BA) parameters, wherein the indication of the BA parameters indicates a buffer size;
• determining a size of a bitmap field based at least in part on the indication of the BA parameters including the buffer size;
• generating a BA frame comprising the bitmap field, a type field indicating a type of the BA frame, and an indication of the determined size of the bitmap field, wherein the bitmap field acknowledges a number of packets correctly received by the apparatus and the determined size of the bitmap field is associated with the type field indicating a type of the BA frame;
• and
• outputting the BA frame for transmission to another apparatus.

An apparatus for wireless communication, comprising:

• means for receiving an indication of block acknowledgment (BA) parameters, wherein the indication of the BA parameters indicates a buffer size;
• means for determining a size of a bitmap field based at least in part on the indication of the BA parameters including the buffer size;
• means for generating a BA frame comprising the bitmap field, a type field indicating a type of the BA frame, and an indication of the determined size of the bitmap field, wherein the bitmap field acknowledges a number of packets correctly received by the apparatus and the determined size of the bitmap field is associated with the type field indicating a type of the BA frame;
• and
• means for outputting the BA frame for transmission to another apparatus.

A computer-readable medium storing computer-executable code for wireless communication by an apparatus, the code when executed by a processor cause the processor to:

• receive an indication of block acknowledgment (BA) parameters, wherein the indication of the BA parameters indicates a buffer size;
• determine a size of a bitmap field based at least in part on the indication of the BA parameters including the buffer size;
• generate a BA frame comprising the bitmap field, a type field indicating a type of the BA frame, and an indication of the determined size of the bitmap field, wherein the bitmap field acknowledges a number of packets correctly received by the apparatus and the determined size of the bitmap field is associated with the type field indicating a type of the BA frame;
• and
• output the BA frame for transmission to another apparatus.
