FIELD: electrical communication engineering.
SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems. Method comprises receiving a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). Received SSS signal can be used as a reference signal for detection of reference demodulation signals (DMRS) of the NR-PBCH. These demodulation reference signals may be interleaved with NR-PBCH data. In one method, the DMR of the NR-PBCH is associated with the SSB index in an attempt to improve randomisation during synchronization. Payload of the NR-PBCH can be demodulated using PSS and/or SSS and DMRS. In one embodiment, the DMRS channel of the NR-PBCH can be mapped to the RE signal elements of the DMRS first based on frequency and then on time.
EFFECT: technical result is to improve the quality of reception.
