A base station may transmit, for a plurality of iterations, a signal to at least one UE through a plurality of transmit chains and with application of DPD. The signal transmitted for each iteration may be transmitted with a BW that extends over a plurality of subcarriers and includes pilots extending over a BW subset that increases in subcarrier size for each iteration. The base station may receive, for each iteration, feedback from the at least one UE based on the transmitted signal and apply DPD to each of the plurality of transmit chains based on the feedback. Accordingly, the base station may transmit to one or more UEs through the plurality of transmit chains and with application of the DPD pilot signals that extend over the entire BW."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Digital predistortion training procedure for massive array","description":"This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a DPD training procedure.
