Title:
USER EQUIPMENT AND METHOD FOR PERFORMING SIDELINK MEASUREMENTS IN V2X COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2021/162476
Kind Code:
A1
Abstract:
Methods and apparatuses in a wireless communication system. A method of operating a user equipment (UE) includes storing a previous layer 3 (L3) filtered measurement result; receiving L3 filtering configuration information including a first filter coefficient value (k) and a first filtering window value; identifying a generation time instance of the previous L3 filtered measurement result; identifying the first filter coefficient value (k) and the first filtering window value included in the L3 filtering configuration information; in response to receiving a latest measurement result from a lower layer, determining whether the generation time instance of the previous L3 filtered measurement result was obtained within a time window that is a function of a first time instance and a second time instance; and performing an L3 filtering operation to trigger a measurement report based on a result of the determination.
