Abstract
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.
Claims8
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.
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.
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.
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.
