Title: RESOURCE MAPPING METHOD FOR DEMODULATION REFERENCE SIGNAL AND BASE STATION
Abstract:
Provided are a resource mapping method for a demodulation reference signal and base station. The method comprises: determining a target orthogonal frequency division multiplexing (OFDM) symbol for mapping a demodulation reference signal of a physical broadcast channel (PBCH) from OFDM symbols corresponding to a new radio (NR) synchronization signal block; and mapping the demodulation reference signal of the PBCH in the target OFDM symbol. The method of the present disclosure determines a target orthogonal frequency division multiplexing (OFDM) symbol for mapping a demodulation reference signal of a physical broadcast channel (PBCH) from OFDM symbols corresponding to a new radio (NR) synchronization signal block and maps the demodulation reference signal of the PBCH in the target OFDM symbol, and thus can perform channel estimation on the PBCH in the synchronization signal block according to the demodulation reference signal.
