Abstract: The present disclosure describes methods, system, and devices for configuring a user equipment (UE) with priority information for measurement task. One method includes sending, by the RAN node, a configuration message to the UE, the configuration message comprising the priority information, so that the UE performs a measurement task and reports at least one measurement result according to the priority information; and receiving, by the RAN node, the at least one measurement result from the UE. Another method includes receiving, by the UE, a configuration message from a radio access network (RAN) node, the configuration message comprising the priority information; and performing, by the UE, a measurement task and reporting at least one measurement result according to the priority information.

Abstract: A radio access network (“RAN”) node or basestation that includes dual functions with both wireless communications and wireless sensing. The sensing related signal may be integrated in the RAN node to provide sensing operations (e.g. sensing radio link S-RL) in addition to wireless communications (e.g. communication radio link RL) with user equipment (“UE”). The sensing signal can be used for detecting objects along a radio path between the RAN node and UE to improve the wireless communication through the communication radio link.
