Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may communicate with a second UE using a sidelink and a retransmission feedback process. The first UE may derive, based at least in part on the communicating, that a sidelink congestion metric satisfies a saturation threshold. The first UE may modify the retransmission feedback process based at least in part on the sidelink congestion metric satisfying the saturation threshold. Numerous other aspects are described.
Claims20
A first user equipment (UE), comprising:
- one or more antennas;
- and
- a processing system that includes one or more processors and one or more memories that store code for the one or more processors, the processing system configured to cause the first UE to:
- communicate with a second UE using a sidelink and a retransmission feedback process, the first UE being a transmitting UE in the retransmission feedback process;
- transmit an indication of a feedback distance;
- derive that a sidelink congestion metric satisfies a saturation threshold;
- and
- modify the retransmission feedback process based at least in part on the sidelink congestion metric satisfying the saturation threshold,
- wherein, to modify the retransmission feedback process, the processing system is configured to cause the first UE to:
- update the feedback distance;
- and
- transmit an indication of the updated feedback distance to the second UE.
A second user equipment (UE), comprising:
- one or more antennas;
- and
- a processing system that includes one or more processors and one or more memories that store code for the one or more processors, the processing system configured to cause the second UE to:
- communicate with a first UE using a sidelink and a retransmission feedback process, the second UE being a receiving UE in the retransmission feedback process;
- receive an indication of a feedback distance;
- derive that a sidelink congestion metric satisfies a saturation threshold;
- receive an updated feedback distance based at least in part on the sidelink congestion metric satisfying the saturation threshold;
- and
- modify the retransmission feedback process based at least in part on the sidelink congestion metric satisfying the saturation threshold,
- wherein, to modify the retransmission feedback process, the processing system is configured to cause the second UE to:
- update the retransmission feedback process with the updated feedback distance.

- and
- modifying the retransmission feedback process based at least in part on the sidelink congestion metric satisfying the saturation threshold,
- wherein modifying the retransmission feedback process comprises:
- updating the feedback distance;
- and
- transmitting an indication of the updated feedback distance to the second UE.
