Abstract

The invention relates to a method for operating user equipment (QQ110) in a wireless network. The method comprises: measuring radio characteristics of a first set of physical resources, the first set of physical resources being available for receiving downlink reference signals for positioning (RSa-RSc) and the first set of physical resources being indicated by a first message (S211) received from a network node (QQ160), selecting a second set of physical resources from the first set of physical resources based on the measured radio characteristics, sending a second message (S122), indicative of the selected second set of physical resources to the network node (QQ160).

Description

technical field [0001] The present invention relates to a method for operating a user equipment UE, in particular for positioning of the UE. The invention also relates to a method for a user equipment, a network node and a user equipment. Background technique [0002] Since 3GPP Release 9, user equipment (UE) location has been one of the many important features of LTE. Due to regulatory requirements, precise identification of the source of an E911 call has also been considered a major feature that New Radio (NR) technology should support. [0003] In order to support UE positioning, typical system architectures have been proposed for LTE and NR respectively. In the LTE positioning architecture, the LTE Positioning Protocol (LPP) and the Radio Resource Control (RRC) protocol are designed to handle the interaction between UE and location server (E-SMLC) and between eNodeB and UE, respectively. Furthermore, LTE Positioning Protocol A (LPPa) has been defined as an interaction...
