Physical Cell ID Detection Performance Using Polarization Receiver Diversity for NR in 3GPP CDL Channel Models

Abstract

This paper presents the physical-layer cell identity (PCID) detection probability using polarization receiver diversity based on the primary and secondary synchronization signals (PSS and SSS) of the New Radio (NR) radio interface for 3GPP clustered delay line (CDL) channel models. We compare the PCID detection probability in the CDL-A, C, and E channel models considering the angle spread of departure and arrival with a tapped delay line (TDL) channel model to validate the PCID detection probability in the CDL channel models. We show that the frequency offset due to the relaxed frequency stability of a local oscillator of a set of user equipment is suppressed to a low level for the PCID detection probability in the CDL channel models. We also show that the PCID detection probability according to the root mean square delay spread is subject to the power delay profile of the CDL channel models. Finally, we show that a high PCID detection probability at the cumulative distribution of 90% is achieved at the average received signal-to-noise ratio (SNR) of approximately -7 dB to -4 dB and -12 dB for non-line-of-sight (NLOS) CDL-C and LOS CDL-E channel models, respectively.
