Abstract
Embodiments of this application provide a communication method, apparatus, and system. In the method, after a first remote radio unit (RRU) determines that a link between the first RRU and a baseband unit (BBU) is in an abnormal state, the first RRU sends information about the first RRU and/or information about an optical module connected to the first RRU to at least one second RRU by using a power line communication (PLC) module in the first RRU. The first RRU is connected to the at least one second RRU by using a power line, and a PLC module is also disposed in the at least one second RRU.
