This application discloses a communication method, apparatus, and system, and a storage medium, and relates to the communication field. The method includes: A first radio unit RU receives device identifiers of m network devices sent by a first network device, where the m network devices include the first network device, the m network devices are connected to each other, and m is an integer greater than 0. The first RU receives device identifiers of n network devices sent by a second RU, where the second RU is connected to the n network devices, and n is an integer greater than 0. The first RU determines, based on the m device identifiers and the n device identifiers, that a same device exists among the m network devices and the n network devices. The first RU performs cooperative communication processing, where the cooperative communication processing is used to implement cooperative communication between the first RU and the second RU. In this application, channels between the first RU and the second RU can be reciprocal.
