본 논문에서는 기지국에서 빔포밍 전송을 통한 5G NR(New Radio) 초기 접속을 위한 주파수 오프셋과 SSS(SecondarySynchronization Signal) 시퀀스의 공동 추정을 사용하는 물리 계층 셀 ID(PCID) 검출 방법을 제안한다. 컴퓨터 시뮬레이션 결과는 제안된 결합 추정과 함께 PCID 검출 방법을 사용하면 평균 수신 신호 대 잡음비(SNR)가 대략 5dB는 잔류 주파수 오프셋이 SSS 시퀀스 추정을 위해 충분히 낮은 수준으로 보상되었음을 나타냅니다. 또한, PCID 검출 방법은 단말 발진기의 주파수 안정성을 위해 반송파 주파수 90, 50GHz에서 각각 30%, 50% 이상의 높은 PCID 검출 확률을 0dB의 평균 수신 SNR에서 달성하는 것으로 나타났다. 3ppm.

Abstract: This paper proposes a physical-layer cell identity (PCID) detection method that uses joint estimation of the frequency offset and secondary synchronization signal (SSS) sequence for the 5G new radio (NR) initial access with beamforming transmission at a base station. Computer simulation results show that using the PCID detection method with the proposed joint estimation yields an almost identical PCID detection probability as the primary synchronization signal (PSS) detection probability at an average received signal-to-noise ratio (SNR) of higher than approximately -5dB suggesting that the residual frequency offset is compensated to a sufficiently low level for the SSS sequence estimation. It is also shown that the PCID detection method achieves a high PCID detection probability of greater than 90% and 50% at the carrier frequency of 30 and 50GHz, respectively, at the average received SNR of 0dB for the frequency stability of a user equipment oscillator of 3ppm.
