In some embodiments, the methods comprise: calculating a threshold associated with a subcarrier; receiving the subcarrier containing an information symbol at the receiver; determining a channel estimate of the subcarrier and a weighting vector for the information symbol; based at least on the channel estimate and the weighting vector, determining a power level of the subcarrier; comparing the power level to the threshold; generating a feedback signal indicating a first energy level to be used for the subcarrier based on the comparison; subsequent to generating the feedback signal, determining a second power level of the subcarrier; comparing the second power level to the threshold; and generating a second feedback signal to the transmitter indicating a second energy level to be used for the subcarrier."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and systems for providing feedback for beamforming and power control","description":"Methods and systems for providing feedback for beamforming and power control are provided.
