A user equipment (UE) may perform a digital simulation to determine a precoding matrix indicator (PMI) associated with a digital reception beam. A base station may send, to the UE, a reference signal. The UE may perform a coarse beam search on the reference signal using non-oversampled digital reception beams. The UE may measure the signal strength of the reference signal for each of the non-oversampled digital reception beams and select the non-oversampled digital reception beam with the strongest signal. The UE may perform a refined beam search procedure on the selected beam by using a set of oversampled digital reception beams which correspond to the selected non-oversampled digital reception beam. The UE may determine the PMI associated with the strongest oversampled digital reception beam and send the PMI in a report to the base station."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Beam search for precoder for channel state feedback","description":"Methods, systems, and devices for wireless communications are described.
