Abstract: The present disclosure provides a communication method and apparatus, to improve link recovery efficiency. The method includes: obtaining first information from a baseband unit BBU, where the first information indicates N1 antenna line devices, the antenna line device is configured to control an antenna, and N1 is a positive integer; and maintaining a connection between a radio frequency device and a first antenna line device, where the first antenna line device is included in the N1 antenna line devices.

Abstract: The present application provides a remote electrical tilt antenna management apparatus, system, and method, a remote controller, and a base station. The method includes: obtaining, by a remote control unit RCU, a first permission configuration file, where the first permission configuration file includes information about a first permission of a first base station to perform an operation on a first remote electrical tilt RET unit, and the first permission includes at least query or control; and configuring, by the RCU according to the first permission configuration file, the first permission of the first base station to perform an operation on the first RET. In this way, the first base station implements configuration of a management operation on the first RET, thereby implementing, by configuring different permission configuration files on the RCU, that a same base station manages different RETs, and further improving operability of managing a RET.
