Abstract: Embodiments of the present invention disclose an interference coordination method and apparatus. The method includes: receiving direction restriction information, where the direction restriction information includes angle restriction information, and the angle restriction information is used to indicate a restricted transmission direction; determining a signal preprocessing manner, where a transmission direction formed based on the signal preprocessing manner does not include the restricted transmission direction; and feeding back the signal preprocessing manner. According to the embodiments of the present invention, signaling overheads can be reduced, and an interference coordination application scenario can be expanded.

Abstract: A data transmission method, a transmitting device, and a receiving device are disclosed. The method is applicable to a wireless communications system including a plurality of beams, and includes: determining, by a transmitting device, beam indication information and at least one transmit beam used for sending data to a receiving device; sending, by the transmitting device, the beam indication information to the receiving device; and transmitting, by the transmitting device, the data by using the at least one transmit beam. The transmitting device sends the beam indication information to indicate, to the receiving device, a corresponding receive beam used for receiving the data transmitted by the transmitting device.
