A terminal obtains a measurement result of a beam; and the terminal sends, to a network device, first indication information used to instruct to deactivate or delete a beam, where the beam satisfies a first quality condition. In addition, the terminal may further obtain a measurement result of the beam, and send, to the network device, second indication information used to instruct to activate or add the beam, to instruct the network device to activate or add a beam having relatively good communication quality, for communication with the terminal. ## Claims ### Claim 1 A communications method applied in a terminal, comprising: receiving beam configuration information from a network device, wherein the beam configuration information configures the terminal to determine whether signal strength of a first beam is greater than a threshold, and the first beam comprises a beam that is not configured by the network device for the terminal to use; and when the signal strength of the first beam is greater than the threshold, sending indication information to the network device requesting the network device to activate or add the first beam for communication of the terminal. ### Claim 2 (depends on 1) The method according to claim 1, wherein the beam configuration information comprises beam identifier information of the first beam. ### Claim 3 (depends on 1) The method according to claim 1, wherein sending the indication information to the network device comprises: sending the indication information to the network device via a medium access control (MAC) layer. ### Claim 4 (depends on 1) The method according to claim 1, further comprising: monitoring the first beam after sending the indication information. ### Claim 5 A communications method applied in a network device, comprising: sending beam configuration information to a terminal, wherein the beam configuration information configures the terminal to determine whether signal strength of a first beam is greater than a threshold, and the first beam comprises a beam that is not configured by the network device for the terminal to use; and when the signal strength of the first beam is greater than the threshold, receiving indication information from the terminal requesting the network device to activate or add the first beam for communication of the terminal. ### Claim 6 (depends on 5) The method according to claim 5, wherein the beam configuration information comprises beam identifier information of the first beam. ### Claim 7 (depends on 5) The method according claim 5, wherein receiving the indication information from the terminal comprises: receiving the indication information from the terminal via a medium access control (MAC)layer. ### Claim 8 An apparatus comprising: a processor; and a memory coupled with the processor and comprising instructions that, when executed by the processor, cause the apparatus to: receive beam configuration information from a network device, wherein the beam configuration information configures the apparatus to determine whether signal strength of a first beam is greater than a threshold, and the first beam comprises a beam that is not configured by the network device for the apparatus to use; and when the signal strength of the first beam is greater than the threshold, send indication information to the network device requesting the network device to activate or add the first beam for communication of the apparatus. ### Claim 9 (depends on 8) The apparatus according to claim 8, wherein the beam configuration information comprises beam identifier information of the first beam. ### Claim 10 (depends on 8) The apparatus according to claim 8, wherein the instructions, when executed by the processor, cause the apparatus further to send the indication information to the network device via a medium access control (MAC)layer. ### Claim 11 (depends on 8) The apparatus according to claim 8, wherein the instructions, when executed by the processor, cause the apparatus further to monitor the first beam after sending the indication information.
