Abstract: A wireless communications system, a scheduling method, a wireless communications method, and an apparatus are provided. Frequencies of operating channels of a plurality of radio access nodes included in a first radio access cell in the wireless communications system are the same. A controller of the system may indicate one radio access node in the first radio access cell to serve as a transceiving access node in a first scheduling period, and indicate another radio access node to serve as an uplink access node. Because in the first scheduling period, the transceiving access node can perform uplink communication and downlink communication with a wireless terminal, and the uplink access node cannot send a radio signal, a problem of co-channel interference can be effectively solved.
