Cet article propose des processus de calcul individuels de la séquence du signal de référence de démodulation partielle (DM-RS) dans un bloc de signal de synchronisation (SS)/canal de diffusion physique (PBCH) à utiliser pour détecter la synchronisation des trames radio sur la base de la détection de l'index de bloc SS/PBCH. pour l’accès initial à New Radio (NR). Nous présentons la probabilité de détection de synchronisation de trame radio à l'aide de la méthode de détection de séquence DM-RS partielle proposée qui est appliquée après la détection de l'identité de cellule de couche physique (PCID) dans cinq modèles de ligne à retard (TDL) à prises dans les deux cas. environnements de vue (NLOS) et de ligne de vue (LOS). Les résultats de simulation informatique montrent qu'en utilisant la méthode proposée, des probabilités de détection de synchronisation de trame radio de près de 100 % et supérieures à 90 % sont atteintes pour les modèles de canal LOS et NLOS, respectivement, au rapport signal/puissance reçu moyen ( SNR) de 0 dB avec la stabilité de fréquence d'un oscillateur local dans un ensemble d'équipements utilisateur (UE) de 5 ppm à la fréquence porteuse de 4 GHz.

Abstract: This paper proposes individual computation processes of the partial demodulation reference signal (DM-RS) sequence in a synchronization signal (SS)/physical broadcast channel (PBCH) block to be used to detect the radio frame timing based on SS/PBCH block index detection for New Radio (NR) initial access. We present the radio frame timing detection probability using the proposed partial DM-RS sequence detection method that is applied subsequent to the physical-layer cell identity (PCID) detection in five tapped delay line (TDL) models in both non-line-of-sight (NLOS) and line-of-sight (LOS) environments. Computer simulation results show that by using the proposed method, the radio frame timing detection probabilities of almost 100% and higher than 90% are achieved for the LOS and NLOS channel models, respectively, at the average received signal-to-noise power ratio (SNR) of 0dB with the frequency stability of a local oscillator in a set of user equipment (UE) of 5ppm at the carrier frequency of 4GHz.
