Abstract
A configuration for virtual sensing via sensor sharing for C-V2X scheduling. The apparatus receives, from a first wireless device, a message indicating a threat entity within a threat zone. The threat entity transmits data that interferes with transmission of BSMs. The apparatus determines a candidate resource of a set of candidate resources on which to transmit a BSM based at least in part on the message indicating information related to the threat entity from the first wireless device. The apparatus transmits, to at least a third wireless device, the BSM on a determined candidate resource.
Claims19
An apparatus for wireless communication at a second wireless device, the apparatus comprising:
- a memory;
- at least one transceiver;
- and
- at least one processor, communicatively connected to the memory and the at least one transceiver, the at least one processor configured to:
- receive, from a first wireless device, a message indicating a threat entity within a threat zone, wherein the threat entity transmits data that interferes with transmission of basic safety messages (BSMs);
- determine a candidate resource of a set of candidate resources on which to transmit a BSM based at least in part on the message indicating information related to the threat entity from the first wireless device, wherein, to determine the candidate resource of the set of candidate resources, the at least one processor is configured to:
- exclude one or more candidate resources in the set of candidate resources based on a projected reference signal received power (RSRP) for each candidate resource in the set of candidate resources exceeding an RSRP threshold to determine a first subset of candidate resources;
- rank the first subset of candidate resources based on a weighted reference signal strength indicator (RSSI) ranking to obtain a second subset of candidate resources with a lowest weighted RSSI, wherein the second subset of candidate resources is a portion of the first subset of candidate resources;
- and
- select a candidate resource from the second subset of candidate resources;
- and
- transmit, to at least a third wireless device, the BSM on a determined candidate resource.
