Abstract

A beam measurement and reporting method, a network side device and a mobile terminal are provided. The method includes: configuring measurement parameters and report parameters for one or more target beam groups, wherein, the measurement parameters include reference signal resources, reference signal resources corresponding to different target beam groups are different, reference signal resources for beams of at least two TRPs in the one or more target beam groups are same; transmitting the measurement parameters and the report parameters to a mobile terminal; controlling beams of the one or more target beam groups to transmit reference signals on reference signal resources corresponding to the beams, wherein the reference signals are used by the mobile terminal to perform beam measurement; receiving a measurement report including measurement results reported by the mobile terminal based on the report parameters.
