Claims 1,7, 9-13, 22-29 and 31-35 are rejected under 35 U.S.C. 103 as being unpatentable over Huang Min et al (WO 2020151741 A1)(see IDS) in view of Kim et al (US 2017/0134201A1)

precoder(precode) in accordance with a subset of time domain precoding taps from a set of time domain precoding taps, each of the set of time domain precoding taps corresponding to a respective precoding value of a set of precoding values associated with a set of subcarriers, and a respective absolute value of each of the subset of time domain precoding taps being greater than a respective absolute value of each of one or more other time domain precoding taps of the set of time domain precoding taps ( see [0007], the method generally includes receiving a channel state information (CSI) report configuration for frequency domain compressed precoder matrix feedback. The CSI report configuration configures the UE to report, for a plurality of selected beans at a plurality of time domain taps- - - quantizing the corresponding linear combination coefficients and/or frequency domain compression basis vectors based on the grouping). Also in [0058]-[0065] -- -In some examples, the grouping is based on more dominant and less dominant linear combination coefficients, a target or threshold payload size, a target or threshold overhead - - - have small value of amplitudes”. Also see figs. 8 and 9, wherein the dominant coefficients corresponding to “subset”, the subset of time domain precoding taps are sent as feedback information node, so that the network code performs precoding on a signal and transmit it.;
