Abstract:
A narrowband PBCH transmission method and a narrowband PBCH transmission device are provided. A network side device transmits a narrowband PBCH carrying at least CRS transmission indication information. The CRS transmission indication information is to indicate the CRS port number and/or CRS frequency domain position in the LTE system. Through the CRS transmission indication information, it is able to enable the narrowband terminal working simultaneously with the LTE terminal in the LTE bandwidth to obtain the CRS in the LTE system, so that the narrowband downlink transmission may be demodulated through the CRS of the LTE system, and then the signal reception based on the CRS may be realized.
