Disclosed are techniques for wireless communication. In an aspect, a position estimation entity configures a sidelink anchor group with sidelink anchor(s), to which respective sidelink PRS pre-configuration(s) are sent. A UE transmits a request to schedule an on-demand sidelink PRS position estimation session of the UE. The position estimation entity provides the UE with assistance data associated with the sidelink anchor group for the on-demand sidelink PRS position estimation session. The UE sends the sidelink anchor group a sidelink PRS trigger to perform a sidelink PRS exchange with some or all of the sidelink anchor group in accordance with the respective sidelink PRS pre-configuration(s).

A device may receive information from a unified database, wherein the information includes a Service Profile Identifier (SPID); select a Quality-of-Service (QoS)-related identifier (ID) at least based on the SPID; and either map a radio bearer to a flow associated with a User Equipment device (UE) or configure a component to map the radio bearer to the flow. After mapping the radio bearer to the flow, the device may send data from the flow to the UE based on the QoS related ID. After configuring the component, the device may forward the SPID to a second component for sending the data from the flow to the UE based on the QoS-related ID.

A method and apparatus for selecting a NR cell in a mobile communication system are provided. Method for selecting a NR cell includes selecting, by a terminal, a first cell, acquiring, by the terminal in the first cell, a MIB, acquiring, by the terminal in the first cell, a SIB1 based at least in part on a first information in the MIB, considering, by the terminal, the first cell as barred, performing, by the terminal a first operation group if the SIB1 received in the first cell does not include a intraFreqReselection and performing, by the terminal a second operation group if the SIB1 received in the first cell includes the intraFreqReselection and the second intraFreqReselection is set to NotAllowed.
