A first IoT device includes a memory, a transceiver, bloom filter evaluation, false positive comparison and control modules. The memory stores: a bloom filter set including an array of bits representing entries in a certificate revocation list; and a false positive set including a list of certificate entries falsely identified as being revoked. The transceiver receives from a second IoT device a message including a certificate. The bloom filter evaluation module receives the bloom filter set from a back office station and determines whether an identifier associated with the certificate is in the bloom filter set. The false positive comparison module receives the false positive set from the back office station and determines whether the identifier is in the false positive set. The control module permits communication between the first and second IoT devices based on whether the identifier is in the bloom filter and false positive sets.

An embodiment relates to a method for a first terminal operating in a wireless communication system, the method comprising the steps of: transmitting application information from an application layer to a vehicle-to-everything (V2X) layer; generating, in the V2X layer, sidelink (SL) discontinuous reception (DRX) information on the basis of the application information; transmitting the SL DRX information from the V2X layer to an AS layer; and communicating with a second terminal by applying the SL DRX information in the AS layer, wherein the application information includes at least one application requirement.

A vehicle computer for use in a vehicle. The vehicle computer includes at least one processor; an interface to a radio communications network; and a memory including software instructions configured to control the at least one processor to implement a method including steps of: receiving, from a traffic information hub in the radio communications network, intersection condition information regarding a next intersection along a route of the vehicle; and calculating route and navigation information based at least in part on the received intersection condition information. Also disclosed is a traffic information hub including: at least one processor; an interface to a data network; and a memory including software instructions configured to control the at least one processor to implement a method including steps of: receiving intersection condition information for each one of a plurality of traffic intersections; and receiving a query from a vehicle.

Embodiments of a user equipment (UE) configured for NR V2X sidelink selection and reselection are generally described herein. In some embodiments, a selected set of candidate resources are scheduled using a single sidelink control information (SCI) within a scheduling window. In some embodiments, sidelink resources are excluded based on a HARQ round trip time. In some embodiments, sidelink control signalling supports the reservation and indication of multiple sidelink resources.

According to some embodiments, there is provided a Collective Perception Message, CPM, characterizing a plurality of Vulnerable Road Users based on a plurality of received VAMs, thereby allowing an ITS station to efficiently aggregate VAM messages from VRUs and retransmit information about the VRUs to other ITS stations. Consequently, the security is improved as some ITS stations may not be able to detect or identify VRU stations by themselves but thanks to the CPM, these stations can still be informed of the VRUs. According to other aspects, congestion is avoided while maintaining safety vis-à-vis VRUs thanks to the use of a different transmission scheme when the VRU is already characterized in a CPM sent to the ITS stations. Also, a receiving station can evaluate whether the content of a CPM can be trusted or not. Safety is thus improved. This is achieved thanks to the CPM that references a certificate.

According to one aspect, a method includes identifying a first signal, which carries or otherwise includes data, to be provided to a system by a vehicle. The method includes determining a first amount of bandwidth, the first amount of bandwidth being associated with the signal, determining a second amount of bandwidth, the second amount of bandwidth being an available bandwidth associated with a plurality of modems included on the vehicle to enable the vehicle to communicate with the system, and dividing the first signal into a first plurality of portions based at least on the first amount of bandwidth and the second amount of bandwidth. The first plurality of portions is provided to the plurality of modems for transmission from the vehicle to the system, and is transmitted to the system using the plurality of modems and a plurality of channels associated with the plurality of modems.
