context: carrier phase positioning is used: - For InF-SH scenario with 1cm ARP error and random initial phase: - (PRU 5m) DD UL-CPP (Case 47): 1.252cm @ 50% and 2.765cm @80% - For InF-SH scenario with 5cm ARP error and random initial phase: - (PRU 5m) DD UL-CPP (Case 48): 5.986cm @ 50% and 0.11879m @80% - Source [80] shows: - For InF-SH scenario with 1cm ARP error: - SD DL-CPP: 0.09m @50% and 0.20m @80%. - For InF-SH scenario with 5cm ARP error: - SD DL-CPP: 0.18m @50%and 0.28m @80% - Source [81] shows: - For InF-SH scenario with 1cm ARP error: - DD DL-CPP (Cases 11): <1.0cm @50% and 11.2cm @80%. - DD DL-CPP (two subcarrier frequencies within one PFL) (Case 12): <1.0cm @50% and 1.79 cm @80%. - DD DL-CPP (two carrier frequencies) (Case 13): <1.0cm @50% and 1.3cm @80%. - For InF-SH scenario with 5cm ARP error: - DD DL-CPP (two carrier frequencies, two PFLs) (Case 15): 3.3cm @50% and 5.6cm @80%. - For InF-DH scenario with 1cm ARP error: - DD DL-CPP (two carrier frequencies, two PFLs) (Case 17):
description: Allocation and Retention Priority (ARP) is a parameter used in carrier phase positioning within 5G networks. It defines the acceptable error tolerance during the allocation and retention process of resources, directly influencing the accuracy of positioning results.
explanation: ARP's role in controlling error tolerance during resource allocation and retention in carrier phase positioning, as described in 3GPP TS 38.859, clearly classifies it as a parameter that affects system performance.
