Consider the scenario defined in clause 5.8, where NR wireless sensing is utilized to assist automotive manoeuvring, i.e. sensing results play an important role in making the manoeuvring decisions. However, in this clause the vehicles are not served by RAN when the Sensing activity is expected to occur, where UE is not served by RAN and therefore RAN entities are unable to be involved. UEs performing the sensing measurement process in this scenario have to be able to operate when UE is not served by RAN.

Refer to clause 5.8, where Bob's vehicle determines the need for sensing service. Bob's vehicle integrates a UE supporting V2X application i.e., Bob's vehicle supports V2X. Sensing can be performed by 5G Wireless sensing. Unlike in section 5.8, the vehicles are not served by RAN and perform 5G Wireless sensing without help of the network entities. Bob's vehicle has been provisioned by his home operator to be able to perform 5G Wireless sensing when not served by RAN. There may be other vehicles or RSU (road side unit) helping the 5G Wireless sensing of the Bob's vehicle.

1. Bob is driving from urban to rural countryside. As his vehicle is operational, in motion, and attempting to assist his driving using ADS, Bob's vehicle is performing sensing using 5G Wireless sensing.
2. Bob drives his vehicle outside the coverage area of its mobile network. The 5G Wireless sensing continues providing assistance to Bob's driving.
3. Bob's vehicle approaches Joe's vehicle.
4. Bob's vehicle becomes aware of Joe's vehicle by Bob's onboard Sensing receiver(s) receiving 5G Wireless sensing reflected by Joe's vehicle.
5. Bob's vehicle applies this new object information to the local ADS function to ensure a safe, collision-free, drive.

Bob's vehicle is able to drive with high reliability by utilizing 5G sensing service when not served by RAN.

None.
