Abstract (en)

[origin: WO2022155465A1] An apparatus and system for accuracy performance testing of positioning reference signals (PRS) signals are described. Multiple groups are used during Reference Signal Time Difference (RSTD) measurement accuracy testing of the UE. The groups are based on multiple PRS parameters, and are dependent on the PRS density but are independent of the subcarrier spacing. The PRS parameters include the number of PRS symbols per resource, repetition factor, and comb size that are all combined to form a normalized PRS length per slot. The RSTD accuracy to be tested is dependent on the frequency range, bandwidth and normalized PRS length.
