Autonomous resource selection for vehicle-to-vehicle sidelink communications

One or more non-transitory computer-readable media including program code, that when executed by one or more processors of a user equipment (“UE”), cause the UE to:

• identify, based on an obtained message, an allocation of spectrum resources to each of a plurality of geographical sub-regions (“GSRs”);
• determine a reference time;
• obtain geo-information of the UE according to the reference time;
• select a set of the spectrum resources for vehicle-to-vehicle (“V2V”) sidelink transmissions based on a position of the UE relative to a GSR of the plurality of GSRs, wherein the position of the UE is based on the geo-information;
• and
• transmit, on the selected set of spectrum resources, the geo-information of the UE.

One or more non-transitory computer-readable media including program code, that when executed by one or more processors of a base station (“BS”), cause the BS to:

• identify a geographic region including a plurality of geographical sub-regions (“GSRs”);
• allocate spectrum resources to each GSR of the plurality of GSRs for one or more vehicle-to-vehicle (“V2V”) sidelink transmissions, wherein the allocation of spectrum resources includes assignment of a same set of the spectrum resources to a first GSR and a second GSR of the plurality of GSRs, wherein the first GSR and the second GSR are spaced apart by a spatial isolation region;
• encode a message for transmission to a user equipment (“UE”) wherein the message is to indicate the allocation of spectrum resources to each GSR, wherein the allocation is for selection of a set of the spectrum resources for the one or more V2V sidelink transmissions by the UE based on a position of the UE relative to a GSR of the plurality of GSRs;
• and
• transmit the encoded message to the UE using radio resource control (RRC) signaling, medium access control (MAC) signaling, or system information block (SIB) signaling.
