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 for a terminal, comprising: receiving beam configuration information from a network device, wherein the beam configuration information comprises a threshold and configures the terminal to determine whether signal strength of a first beam is greater than the threshold, and the first beam is a beam that is different from a beam configured for the terminal to perform data transmission; and determining that the signal strength of the first beam is greater than the threshold and one or more of activated beams of the terminal fail to satisfy a first quality condition, and based thereon, requesting the first beam to be activated or added by the network device, wherein the first beam is for communication of the terminal, and wherein the requesting comprises sending indication information to the network device via a medium access control (MAC) layer. ### Claim 2 (depends on 1) The method according to claim 1, wherein the beam configuration information further comprises beam identifier information of the first beam. ### Claim 3 (depends on 1) The method according to claim 1, further comprising: monitoring the first beam after requesting the first beam to be activated or added. ### Claim 4 (depends on 1) The method according to claim 1, wherein the one or more of activated beams that do not satisfy the first quality condition are deactivated or deleted. ### Claim 5 (depends on 1) The method according to claim 1, wherein the first beam is a beam that is different from any beam configured for the terminal to perform data transmission. ### Claim 6 A communications method applied in a network device, comprising: sending beam configuration information to a terminal, wherein the beam configuration information comprises a threshold and configures the terminal to determine whether signal strength of a first beam is greater than the threshold, and the first beam is a beam that is different from a beam configured for the terminal to perform data transmission; and in response to the signal strength of the first beam being greater than the threshold and one or more of activated beams of the terminal failing to satisfy a first quality condition, receiving a request from the terminal via a medium access control (MAC) layer requesting the first beam to be activated or added for communication of the terminal. ### Claim 7 (depends on 6) The method according to claim 6, wherein the beam configuration information further comprises beam identifier information of the first beam. ### Claim 8 (depends on 6) The method according to claim 6, wherein the one or more of activated beams that do not satisfy the first quality condition are deactivated or deleted. ### Claim 9 (depends on 6) The method according to claim 6, wherein the first beam is a beam that is different from any beam configured for the terminal to perform data transmission. ### Claim 10 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 comprises a threshold and configures the apparatus to determine whether signal strength of a first beam is greater than the threshold, and the first beam is a beam that is different from a beam configured for a terminal to perform data transmission; and determine that the signal strength of the first beam is greater than the threshold and one or more of activated beams of the apparatus fail to satisfy a first quality condition, and based thereon, request the first beam to be activated or added by the network device, wherein the first beam is for communication of the apparatus, and wherein the requesting comprises sending indication information to the network device via a medium access control (MAC) layer. ### Claim 11 (depends on 10) The apparatus according to claim 10, wherein the beam configuration information further comprises beam identifier information of the first beam. ### Claim 12 (depends on 10) The apparatus according to claim 10, wherein the instructions, when executed by the processor, cause the apparatus further to monitor the first beam after requesting the first beam to be added or activated. ### Claim 13 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: send beam configuration information to a terminal, wherein the beam configuration information comprises a threshold and configures the terminal to determine whether signal strength of a first beam is greater than the threshold, and the first beam is a beam that is different from a beam configured for the terminal to perform data transmission; and in response to the signal strength of the first beam being greater than the threshold and one or more of activated beams of the terminal failing to satisfy a first quality condition, receive a request via a medium access control (MAC) layer requesting the first beam to be activated or added for communication of the terminal. ### Claim 14 (depends on 13) The apparatus according to claim 13, wherein the beam configuration information comprises beam identifier information of the first beam. ### Claim 15 (depends on 13) The apparatus according to claim 13, wherein the one or more of activated beams that do not satisfy the first quality condition are deactivated or deleted.
