Abstract: The disclosure provides methods of providing implicit channel state information (CSI) feedback from a user equipment (UE). A method performed by a first device includes determining a feedback parameter selection decision metric; selecting a particular method from a plurality of methods, based on the feedback parameter selection decision metric; determining, based at least in part on the particular method, and based on a configuration of an associated second device, one or more values associated with precoding; and transmitting the one or more values to the second device.

Abstract: The disclosure provides a method of providing implicit channel state information (CSI) feedback from a user equipment (UE). The method includes determining a precoding matrix indicator (PMI) selection decision metric, selecting one of a sub-band (SB) linear combination coefficient (LCC) selection method, a wideband (WB) LCC selection method, or a sub-band group (SBG) LCC selection method, based on the determined PMI selection decision metric, determining, using the selected LCC selection method, PMI indices based on sub-bands configured by a base station, and transmitting the determined PMI indices to the base station.
