Abstract
Techniques pertaining to dynamic link selection for reliable retransmission in wireless communications are described. A multi-link device (MLD) establishes a block acknowledgement (Block Ack) agreement or a protected Block Ack agreement with one other MLD on one or more enabled links for dynamic link selection. The MLD communicates with the other MLD on at least one of the one or more enabled links prior to termination of the Block Ack agreement or the protected Block Ack agreement.
Claims16
A method, comprising:
- establishing, by a processor of a multi-link device (MLD), a block acknowledgement (Block Ack) agreement or a protected Block Ack agreement with one other MLD on multiple enabled links mapped by traffic identifier-to-link mapping (T2LM);
- and
- communicating, by the processor, with the other MLD on at least one of the multiple enabled links prior to termination of the Block Ack agreement or the protected Block Ack agreement, wherein the communicating comprises:
- selecting a link from the multiple enabled links, wherein the selected link is among one or more ongoing communication links protected by a current transmission opportunity (TXOP), which comprises a period reserved for transmission between the MLD and the other MLD;
- and
- transmitting, on the selected link, to the other MLD a Block Ack with a consolidated receiving status of a data transmission transmitted from the other MLD in response to receiving a Block Ack request (BAR) or a multi-link BAR (ML-BAR), from the other MLD, wherein the consolidated receiving status means a receiving status consolidated from a link level scoreboard into a MLD level scoreboard;
- or
- transmitting, on the selected link, to the other MLD a Block Ack with a consolidated receiving status of a data transmission transmitted from the other MLD in response to receiving one or more data packets from the other MLD, wherein the consolidated receiving status means a receiving status consolidated from a link level scoreboard into a MLD level scoreboard.

An apparatus implementable in a multi-link device (MLD), comprising:
- a transceiver configured to communicate wirelessly;
- and
- a processor coupled to the transceiver and configured to perform, via the transceiver, operations comprising:
- establishing, via the transceiver, a block acknowledgement (Block Ack) agreement or a protected Block Ack agreement with one other MLD on multiple enabled links mapped by traffic identifier-to-link mapping (T2LM);
- and
- communicating, via the transceiver, with the other MLD on at least one of the multiple enabled links prior to termination of the Block Ack agreement or the protected Block Ack agreement, wherein the communicating comprises:
- selecting a link from the multiple enabled links, wherein the selected link is among one or more ongoing communication links protected by a current transmission opportunity (TXOP), which comprises a period reserved for transmission between the MLD and the other MLD;
- and
- transmitting, on the selected link, to the other MLD a Block Ack with a consolidated receiving status of a data transmission transmitted from the other MLD in response to receiving a Block Ack request (BAR) or a multi-link BAR (ML-BAR), from the other MLD, wherein the consolidated receiving status means a receiving status consolidated from a link level scoreboard into a MLD level scoreboard;
- or
- transmitting, on the selected link, to the other MLD a Block Ack with a consolidated receiving status of a data transmission transmitted from the other MLD in response to receiving one or more data packets from the other MLD, wherein the consolidated receiving status means a receiving status consolidated from a link level scoreboard into a MID level scoreboard.
