A beam transmitted by a transmission source is received at a receiving device. The received beam is affected by an interference signal from an interfering source. The receiving device computes a covariance matrix that represents a channel estimate associated with the interfering source. The receiving device modifies a predetermined sounding signal based on the covariance matrix for transmission to the transmission source. The receiving device causes the transmission source to estimate an equivalent channel matrix based on the predetermined sounding signal and the modified predetermined sounding signal. The equivalent channel matrix represents the channel estimate associated with the interfering source and a channel estimate associated with the transmission source."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for directing a beam towards a device in the presence of interference based on reciprocity","description":"Methods and apparatus are provided for directing a beam towards a receiving device in the presence of interference.
