摘要： Methods and apparatus are provided for directing a beam towards a receiving device in the presence of interference. A beam transmitted by a transmission source is received by a received device. The beam shape is affected by signals transmitted by interfering sources. The receiving device computes channel estimates associated with the transmission source and the interfering sources. A feedback signal that represents the channel estimates associated with the transmission and interfering sources is transmitted to the transmission source. The transmission source changes characteristics of the beam to compensate for the interference caused by the interfering sources. The transmission source may change the characteristics of the beam by performing precoding algorithms.
