1. A method, comprising:
determining, using vehicle-to-everything (V2X) communications, that a vehicle is a safety-relevant vehicle posing a potential danger to a vulnerable road user (VRU); and
receiving only transmissions of the safety-relevant vehicle and skipping reception of transmissions of non-safety-relevant vehicles by:
identifying periodically a slot and a respective subchannel for V2X transmission of the safety-relevant vehicle, and receiving the current slot and respective subchannel if the current slot and respective subchannel are identified as allocated to the safety-relevant vehicle, or skipping the reception of the current slot and respective subchannel if the current slot and respective subchannel are not identified as allocated to the safety-relevant vehicle,
terminating the reception of the current slot and respective subchannel if the current slot and respective subchannel are identified as allocated to the safety-relevant vehicle but do not include transmissions of the safety-relevant vehicle, and
if the current slot and respective subchannel do not include transmissions of the safety-relevant vehicle, scanning for transmissions of the safety-relevant vehicle in slots and respective subchannels proximal to the current slot and subchannel and, upon finding such proximal slots and respective subchannels, updating a database with the found slots and respective subchannels,
thereby lowering V2X reception power consumption of a device carried by the VRU.
