Title: INFORMATION TRANSMISSION METHOD, APPARATUS, AND SYSTEM
Abstract:
The embodiments of the present invention provide an information transmission method, comprising a user equipment (UE) transmitting a measurement reference signal, the subcarrier spacing of said measurement reference signal being a multiple of the subcarrier spacing of the data channel of said UE. The method may comprise the UE receiving configuration information from a wireless network device; said configuration information comprises information used for configuring the UE to transmit the measurement reference signal; information of the measurement reference signal comprises information of the subcarrier spacing of the measurement reference signal. Thus the transmission overhead of reference signals is reduced.
