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.

Abstract: An example antenna system includes a first antenna including a strip-shaped antenna radiator. The antenna radiator has a first end and a second end. At least one of a first radiator section in which the first end is located or a second radiator section in which the second end is located is used as a radiator of a second antenna. One of two first filters is connected between the first antenna radio frequency source and an antenna feed point, and the other first filter is connected between a ground and an antenna ground point. One of two second filters is connected between the second antenna radio frequency source and at least one of the first radiator section or the second radiator section, and the other second filter is connected between the ground and at least one of the first radiator section or the second radiator section.
