Abstract: A measurement apparatus and method. The method includes sending, by a radio access network system, information about a subframe mode corresponding to at least one beam, where the information about the subframe mode instructs a UE to perform measurement according to the information about the subframe mode, and the method further includes receiving, by the radio access network system, a measurement result sent by the UE. The measurement apparatus and method can be used to perform the measurement in a millimeter wave scenario.

Abstract: The present invention provides a broadcast message transmission method, a base station and user equipment. The method includes: determining a resource position of a broadcast channel, wherein the broadcast channel occupies M physical resource blocks (PRBs) among m PRBs of a frequency band center of a carrier, m and M are positive integers, M is not greater than m, and m is not greater than the number of the PRBs corresponding to the system bandwidth; mapping the broadcast channel on the resource position; and sending a broadcast message through the broadcast channel. In the embodiments of the present invention, since the broadcast channel occupies M PRBs among m PRBs of a frequency band center of a carrier, by mapping the broadcast channel on the resource position and sending a broadcast message through the broadcast channel, the resource utilization rate of the carrier may be improved.
