"Semi-open-loop MIMO transmission based on type-II precoding matrices" was invented by Weimin Duan (San Diego) and Hyojin Lee (San Diego).
According to the abstract* released by the U.S. Patent & Trademark Office: "Aspects presented herein may improve multiple-input multiple-output (MIMO) operations by providing a semi-open-loop MIMO scheme with a higher granularity. In one aspect, a network entity formulates, based on wideband (WB) channel state information of a channel from a user equipment (UE), a set of precoding matrices to be applied on a set of resource blocks (RBs) or a set of resource elements (REs) for a...
