Apparatus and methods for block acknowledgment compression
Systems, methods, and devices for compressing block acknowledgment (ACK) frames/packets are described herein. In some aspects, a method of communicating in a wireless network includes generating a compressed block acknowledgment frame comprising one or more local addresses. The method further includes transmitting the compressed block acknowledgment frame.
1. A method of communicating in a wireless network, the method comprising:
generating a block acknowledgment frame comprising one or more local addresses identifying one or more wireless stations within a basic service set and one or more global addresses identifying one or more wireless stations globally;
generating a physical layer (PHY) header comprising a signal (SIG) field including an identifier of the block acknowledgment portion, a bitmap, and a starting sequence number of a packet acknowledged in the bitmap; and
transmitting the PHY header and the block acknowledgment frame in a message, the block acknowledgment frame omitting each of a duration field, a traffic identifier field (TID), and a reserved subfield.
2. The method of claim 1 , wherein generating the block acknowledgement frame includes compressing the block acknowledgment frame, wherein compressing the block acknowledgment frame comprises:
generating a bitmap using run-length encoding; and
including the bitmap in the block acknowledgment frame.
3. A wireless device, comprising:
a processor configured to:
generate a block acknowledgment frame comprising one or more local addresses identifying one or more wireless stations within a basic service set and one or more global addresses identifying one or more wireless stations globally;
generate a physical layer (PHY) header comprising a signal (SIG) field including an identifier of the block acknowledgment portion, a bitmap, and a starting sequence number of a packet acknowledged in the bitmap; and
a transmitter configured to transmit the PHY header and the block acknowledgment frame in a message, the block acknowledgement frame omitting each of a duration field, a traffic identifier field (TID), and a reserved subfield.
4. The wireless device of claim 3 , wherein generating the block acknowledgement frame includes compressing the block acknowledgment frame, wherein compressing the block acknowledgment frame comprises:
generating a bitmap using run-length encoding; and
including the bitmap in the block acknowledgment frame.
5. A wireless device, comprising:
means for generating a block acknowledgment frame comprising one or more local addresses identifying one or more wireless stations within a basic service set and one or more global addresses identifying one or more wireless stations globally;
means for generating a physical layer (PHY) header comprising a signal (SIG) field including an identifier of the block acknowledgment portion, a bitmap, and a starting sequence number of a packet acknowledged in the bitmap; and
means for transmitting the PHY header and the block acknowledgment frame in a message, the block acknowledgement frame omitting each of a duration fielder traffic identifier field (TID), and a reserved subfield.
6. The wireless device of claim 5 , wherein generating the block acknowledgement frame includes compressing the block acknowledgment frame, wherein compressing the block acknowledgment frame comprises:
generating a bitmap using run-length encoding; and
including the bitmap in the block acknowledgment frame.
7. A non-transitory computer-readable medium comprising code that, when executed, causes an apparatus to:
generate a block acknowledgment frame comprising one or more local addresses identifying one or more wireless stations within a basic service set and one or more global addresses identifying one or more wireless stations globally;
generate a physical layer (PHY) header comprising a signal (SIG) field including an identifier of the block acknowledgment portion, a bitmap, and a starting sequence number of a packet acknowledged in the bitmap; and
transmit the PHY header and the block acknowledgment frame in a message, the block acknowledgment frame omitting each of a duration field, a traffic identifier field (TID), and a reserved subfield.
8. The computer-readable medium of claim 7 , wherein generating the block acknowledgement frame includes compressing the block acknowledgment frame, wherein compressing the block acknowledgment frame comprises:
generating a bitmap using run-length encoding; and
including the bitmap in the block acknowledgment frame.
