full_form: LTE Positioning Protocol
context: sample may be required at the UE subject to measurement conditions. Lower Rx beam sweeping factor: In Rel-17, a new UE capability on lower Rx beam sweeping factor (<8) is introduced to reduce the PRS measurement latency for FR2 positioning frequency layers. Storing LPP capability in AMF: The LMF may interact with the AMF to provide (updated) UE Positioning Capability to AMF and to receive stored UE Positioning Capability from AMF as described in TS 23.273. The LPP procedures to transfer UE LPP positioning capabilities may be skipped if the LMF already obtained the UE positioning capabilities from the AMF. Preconfigured assistance data: Preconfigured assistance data is the DL-PRS assistance data (with associated validity criteria, i.e. area ID) that can be provided to the UE (before or during an ongoing LPP positioning session), to be then utilized for potential positioning measurements at a future time (e.g. for deferred MT-LR). Pre-configured DL-PRS assistance data may consist of
description: LTE Positioning Protocol (LPP) is a protocol used in LTE networks to enable location-based services and positioning capabilities. It facilitates the exchange of information between the network and user equipment (UE) for determining the UE's location.
explanation: The text explicitly states that LPP is a protocol used in LTE networks for positioning purposes. Protocols define rules and formats for communication, and LPP governs the exchange of location-related data between network components and user devices.
