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(shuō)明書

In some aspects, the base station 510 may instruct the Rx UEs 515 to adjust resource usage, to reschedule D2D communications scheduled on non-corresponding resource allocations, to prevent transmission of D2D communications on non-corresponding resource allocations, and/or the like. An Rx UE 515 may perform one or more of these operations, as described in more detail in connection with FIG. 4, based at least in part on the instruction received by the base station 510. Additionally, or alternatively, the Rx UE 515 may autonomously perform one or more of these operations without an explicit instruction from the base station 510, in a similar manner as described above in connection with FIG. 4.

As shown by reference number 545, Tx UEs 505 and Rx UEs 515 may communicate using the determined resource allocations, which may be dynamically configured and/or adjusted over time. By slicing resources of a sidelink channel (e.g., the PSSCH and/or the like) in this manner, resource usage and spectral efficiency may be improved. Furthermore, such slicing of resources may assist with improving performance and/or meeting communication requirements of various services.

As indicated above, FIG. 5 is provided as an example. Other examples may differ from what is described with respect to FIG. 5.

FIG. 6 is a diagram illustrating an example process 600 performed, for example, by a UE, in accordance with various aspects of the present disclosure. Example process 600 is an example where a UE (e.g., UE 120 and/or the like) performs operations associated with resource slicing on a sidelink interface.
