Abstract

The present disclosure relates to a cell measurement method and apparatus, and a readable storage medium, which apply to the technical field of wireless communication. The cell measurement method comprises: receiving a beam-off notification sent from network equipment; the beam-off notification indicates at least one beam to be turned off; determining the cell measurement on the basis of the measurement for a beam which is not to be turned off. In the present invention, the beam-off notification sent by the network equipment to user equipment allows the user equipment to learn of the beam to be turned off. Thus, when carrying out cell measurement, the user equipment does not need to consider the beam to be turned off. This can reduce the processing capacity required of the user equipment. Furthermore this allows the user equipment to select a more suitable cell or make a more accurate measurement of the cell to be measured, thereby providing the requisite conditions for reducing the energy consumption of the base station.
