Abstract
Certain embodiments of the present disclosure propose techniques for improving automatic repeat request (ARQ) feedback messages to reduce unnecessary transmissions by notifying the transmitter of the last acknowledged block in the ARQ feedback message.
Claims44
A method for wireless communications, comprising:
- receiving an Automatic Repeat-Request (ARQ) feedback message;
- determining a last block acknowledged based on the ARQ feedback message;
- and
- ignoring one or more bits in the ARQ feedback message after the last block acknowledged.
A method for wireless communications, comprising:
- receiving an Automatic Repeat-Request (ARQ) block;
- generating an ARQ feedback message including an indication of a last block acknowledged from the ARQ block;
- and
- transmitting the ARQ feedback message.
An apparatus for wireless communications, comprising:
- logic for receiving an Automatic Repeat-Request (ARQ) feedback message;
- logic for determining a last block acknowledged based on the ARQ feedback message;
- and
- logic for ignoring one or more bits in the ARQ feedback message after the last block acknowledged.
An apparatus for wireless communications, comprising:
- logic for receiving an Automatic Repeat-Request (ARQ) block;
- logic for generating an ARQ feedback message including an indication of a last block acknowledged from the ARQ block;
- and
- logic for transmitting the ARQ feedback message.
An apparatus for wireless communications, comprising:
- means for receiving an Automatic Repeat-Request (ARQ) feedback message;
- means for determining a last block acknowledged based on the ARQ feedback message;
- and
- means for ignoring one or more bits in the ARQ feedback message after the last block acknowledged.
An apparatus for wireless communications, comprising:
- means for receiving an Automatic Repeat-Request (ARQ) block;
- means for generating an ARQ feedback message including an indication of a last block acknowledged from the ARQ block;
- and
- means for transmitting the ARQ feedback message.

- instructions for receiving an Automatic Repeat-Request (ARQ) feedback message;
- instructions for determining a last block acknowledged based on the ARQ feedback message;
- and
- instructions for ignoring one or more bits in the ARQ feedback message after the last block acknowledged.
A computer-program storage apparatus for wireless communications, comprising a computer readable medium having instructions stored thereon, the instructions being executable by one or more processors and the instructions comprising:
- instructions for receiving an Automatic Repeat-Request (ARQ) block;
- instructions for generating an ARQ feedback message including an indication of a last block acknowledged from the ARQ block;
