Abstract: The present application discloses a beam switching method for an intermediate node, applied to a wireless communication system. The wireless communication system includes a network device, an intermediate node apparatus, and user equipment. On a user node side, control information is received, wherein the control information includes a beam switching indication for the intermediate node; within a first threshold duration after receiving the control information, downlink control signaling and/or data are/is forwarded by using a beam controlled by an intermediate node before switching; and after a sum of the first threshold duration and a second threshold duration following receiving of the control information, the downlink control signaling and/or the data are/is forwarded by using a beam controlled by an intermediate node after switching. The present application further includes a device and system for implementing the method described.
