The disclosure describes a method for a network entity (NE) to optimize positioning of a user equipment (UE) based on static circumstances and situational/environmental circumstances. The static circumstances may be sensor capabilities and sensor quality related to the UE, radio access network (RAN) capabilities, or general system limitations. The NE may request a quality report from a measurement unit (MU) that indicates the positioning technologies used for such quality reporting. The NE may inform the MU which sensors and technologies to use for monitoring and request a report from these sensors and technologies. The NE may receive results from measurements performed by the MU, and the NE may receive a message including the MU quality report in order to enable the NE to decide on the best positioning method for the UE in the current situation for the indicated sensors and technologies to perform the position calculation.

Method and system for optimizing the position of a user equipment

A transceiver for a wireless communication system is configured to: communicate with at least one other transceiver of the system using a sidelink resource pool of the system; transmit signals on resources of the pool that are allocated to the transceiver on a period basis with equal length periods t; transmit a first signal on a first resource of the resources allocated to the transceiver, and receive a second signal from another transceiver of the system on a second resource, the second signal being transmitted by the other transceiver responsive to a reception of the first signal, the second signal being transmitted by the other transceiver on the second resource using the period tbased on which the resources are allocated to the transceiver; determine a distance to the other transceiver based on a time tbetween the transmission of the first signal and the reception of the second signal from the other transceiver, and based on the period tbased on which the resources are allocated to the transceiver.

Sidelink ranging and multilateration

The embodiments herein relate to method performed by a measurement device, the method comprising: receiving via higher layer signalling, information on resources or resource sets of one or more radio transmission devices transmitting one or more beam signals associated with said resources or resource sets; performing channel measurements of the one or more beam signals, per spatial filter or receiver beam of the measurement device; storing, over at least one time frame, the channel measurements into measurement groups, where each measurement group corresponds to the channel measurements performed using the same spatial filter of the measurement device; and reporting the measurement groups to a network node or correlating the measurements of each measurement group with reference data for each available time frame individually and reporting the result of the correlation to the network node. The embodiments also relate to a method performed by a network node.
