摘要

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a service type to be used by the UE for one or more device-to-device (D2D) communications on a sidelink interface; determine a slice identifier based at least in part on the service type, wherein the slice identifier corresponds to a resource allocation to be used for the one or more D2D communications; and transmit an indication of the slice identifier. Numerous other aspects are provided.

說明書

In some aspects, the Rx UE 410 may reconfigure one or more slices (e.g., resource allocations) used for service types that do not correspond to the received slice identifiers. For example, the Rx UE 410 may reduce a size of such a slice (e.g., by reducing the number of resources included in a resource allocation corresponding to the slice). In some aspects, the Rx UE 410 may equally reduce a size of all slices that do not correspond to the received slice identifiers. Alternatively, the Tx UE 405 and/or a base station 110 may indicate a manner in which one or more slices are to be adjusted, and the Rx UE 410 may adjust a resource allocation of the one or more slices accordingly.

In some aspects, the Rx UE 410 may adjust one or more slices using a rule-based prioritization of slices. For example, different slices may be associated with different priority levels, and such priority levels may be used to determine a manner in which the slices are adjusted. For example, the Rx UE 410 may reduce a size of the lowest priority slice being used by the Rx UE 410 until the resource allocation corresponding to the received slice identifier(s) is satisfied. In some aspects, the size of the lowest priority slice may be reduced down to a minimum slice size for that slice, and a size of a next-lowest priority slice may be reduced, and so on, until the resource allocation corresponding to the received slice identifier(s) is satisfied. In some aspects, the prioritization may indicate a set of weight values to be applied to reduce the size of multiple slices, where a higher weight value applied to a slice results in more resources or a higher percentage of resources being removed from that slice as compared to another slice with a lower weight value.
