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. ## Claims ### Claim 1 A method of wireless communication performed by a user equipment (UE), comprising: determining a service type to be used by the UE for one or more device-to-device (D2D) communications on a sidelink interface; determining 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 transmitting an indication of the slice identifier. ### Claim 2 (depends on 1) The method of claim 1, wherein the one or more D2D communications include one or more vehicle-to-everything (V2X) communications. ### Claim 3 (depends on 1) The method of claim 1, wherein the slice identifier is further determined based at least in part on a set of quality of service parameters associated with the service type. ### Claim 4 (depends on 1) The method of claim 1, wherein the service type is represented using at least one of an upper layer identifier, a provider service identifier (PSID), an intelligent transport system application identifier (ITS-AID), or a combination thereof. ### Claim 5 (depends on 1) The method of claim 1, wherein the resource allocation is determined based at least in part on a data structure that maps different resource allocations to corresponding slice identifiers or service type identifiers. ### Claim 6 (depends on 5) The method of claim 5, wherein the data structure is pre-configured on the UE, provisioned for the UE, or dynamically configured for the UE based at least in part on an indication received from a base station. ### Claim 7 (depends on 1) The method of claim 1, wherein the resource allocation is determined based at least in part on an indication received from a base station in connection with transmitting the indication of the slice identifier. ### Claim 8 (depends on 7) The method of claim 7, wherein the indication from the base station is received in a radio resource control (RRC) message or a system information block. ### Claim 9 (depends on 1) The method of claim 1, further comprising communicating using a set of resources of the resource allocation. ### Claim 10 (depends on 1) The method of claim 1, wherein the slice identifier indicates at least one of a slice type associated with the service type, a sub-slice type associated with the service type, a slice instance associated with the service type, or a combination thereof. ### Claim 11 (depends on 1) The method of claim 1, further comprising indicating a requested duration for use of a slice identified by the slice identifier, a requested slice size associated with the slice identifier, or a combination thereof. ### Claim 12 (depends on 1) The method of claim 1, wherein the indication of the slice identifier is transmitted in at least one of a non-access stratum (NAS) message over the sidelink interface, a radio resource control (RRC) message to a UE, an RRC message to a base station, a header of a D2D communication, or a combination thereof. ### Claim 13 (depends on 1) The method of claim 1, wherein the slice identifier is determined based at least in part on a data structure that maps different slice identifiers to corresponding service type identifiers. ### Claim 14 (depends on 1) The method of claim 1, wherein the service type includes at least one of a location-based service, an intersection assist service, a platooning service, a cooperative adaptive cruise control service, a sensor sharing service, or a combination thereof. ### Claim 15 (depends on 1) The method of claim 1, wherein the service type is represented by an identifier that is not readable at an access stratum layer, and wherein the slice identifier is readable at the access stratum layer. ### Claim 16 (depends on 1) The method of claim 1, wherein the indication of the slice identifier further indicates a permitted quality of service upgrade, a permitted quality of service downgrade, or a quality of service migration path. ### Claim 17 (depends on 1) The method of claim 1, wherein the indication of the slice identifier further indicates a capability of the UE. ### Claim 18 A method of wireless communication performed by a first user equipment (UE), comprising: receiving an indication of a slice identifier that identifies a slice type to be used by a second UE, wherein the slice identifier corresponds to a service type and a resource allocation to be used for one or more device-to-device (D2D) communications of the second UE on a sidelink interface; determining the resource allocation based at least in part on the slice identifier; and preventing the first UE from using resources indicated by the resource allocation for transmission of communications not associated with the service type. ### Claim 19 (depends on 18) The method of claim 18, wherein the one or more D2D communications include one or more vehicle-to-everything (V2X) communications. ### Claim 20 (depends on 18) The method of claim 18, wherein the indication is received from at least one of the second UE, a base station, or a combination thereof. ### Claim 21 (depends on 18) The method of claim 18, wherein the resource allocation is determined based at least in part on a data structure that maps different resource allocations to corresponding slice identifiers. ### Claim 22 (depends on 21) The method of claim 21, wherein the data structure is pre-configured on the first UE, provisioned for the first UE, or dynamically configured for the first UE based at least in part on an indication received from a base station. ### Claim 23 (depends on 18) The method of claim 18, wherein the resource allocation is determined based at least in part on an indication received from a base station. ### Claim 24 (depends on 23) The method of claim 23, wherein the indication from the base station is received in a radio resource control (RRC) message or a system information block. ### Claim 25 (depends on 18) The method of claim 18, wherein the indication of the slice identifier is received in at least one of a non-access stratum (NAS) message over the sidelink interface, a radio resource control (RRC) message from the second UE, an RRC message from a base station, a header of a D2D communication, or a combination thereof. ### Claim 26 (depends on 18) The method of claim 18, wherein the indication of the slice identifier further indicates a capability of the second UE. ### Claim 27 (depends on 26) The method of claim 26, further comprising communicating with the second UE based at least in part on the capability. ### Claim 28 (depends on 18) The method of claim 18, wherein the first UE is prevented from using the resources indicated by the resource allocation based at least in part on a rule-based prioritization of slices or slice types, an instruction received from the second UE, an instruction received from a base station, or a combination thereof. ### Claim 29 A method of wireless communication performed by a base station, comprising: receiving an indication of a slice identifier that identifies a slice type to be used by a user equipment (UE), wherein the slice identifier corresponds to a service type and a resource allocation to be used for one or more device-to-device (D2D) communications of the UE on a sidelink interface; and indicating at least one of the slice identifier or the resource allocation to one or more UEs in a coverage area of the base station. ### Claim 30 A user equipment (UE) for wireless communication, comprising: memory; and one or more processors operatively coupled to the memory, the memory and the one or more processors configured to: 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.
