Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may establish a sidelink with a second UE using at least a set of reference sidelink configuration parameters. The UE may update the sidelink using a set of location-based delta sidelink configuration parameters that are based at least in part on a sidelink location that includes at least one of: a first location of the first UE, or a second location of the second UE. Numerous other aspects are described.
Claims20
A first user equipment (UE), comprising:
- one or more antennas;
- and
- a processing system, coupled with the one or more antennas, 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:
- establish a sidelink with a second UE using at least a set of reference sidelink configuration parameters;
- receive a first medium access control (MAC) control element (CE) that is carried by a first transmission, the first MAC CE indicating a first coverage zone that satisfies a distance condition for a sidelink location, and the first transmission carrying first application layer data,
- wherein the sidelink location includes at least one of:
- a first location of the first UE, or
- a second location of the second UE;
- receive a second MAC CE that is carried by a second transmission, the second MAC CE indicating a second coverage zone that satisfies the distance condition for the sidelink location, and the second transmission carrying second application layer data;
- calculate a first signal strength metric using the first transmission;
- calculate a second signal strength metric using the second transmission;
- select a set of location-based delta sidelink configuration parameters from the first application layer data or from the second application layer data based at least in part on the sidelink location and on one or more of:
- the first coverage zone or the second coverage zone satisfying the distance condition, or
- whether the first signal strength metric is higher than the second signal strength metric;
- and
- update the sidelink using the set of location-based delta sidelink configuration parameters.
