1. A method of a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a network entity, configuration information for multiple frequency layers, wherein each frequency layer of the multiple frequency layers corresponds to contiguous frequencies allocated to one or more cells associated with the each frequency layer and includes resources to which a positioning reference signal (PRS) is mapped; and
receiving, from one or more cells, the PRS based on the configuration information,
wherein the each frequency layer is configured to support a single numerology and a single PRS density, the single numerology being associated with a value of a subcarrier spacing (SCS) configuration,
wherein a start physical resource block (PRB) for the each frequency layer is defined relative to point A, and the point A for PRS resource allocation is provided per frequency layer, and up to 4 frequency layers are configurable for the UE,
wherein K frequency layers among the multiple frequency layers are activated for the UE based on whether a measurement gap is configured or not,
based on the measurement gap not being configured, the UE is capable of measuring for a frequency layer within an active bandwidth part (BWP), and
based on the measurement gap being configured, the UE is capable of measuring outside the active BWP and measuring frequency layers at one time depending on UE capability.
