Publication number: 20230291456Abstract: Systems and methods are provided that involve the design and use of beam sets for CSI feedback that are customized for to a given environment, for example, a room, a hallway, an outdoor area, an indoor area. This can have the effect of reducing the number of beams within the beam set that are used to represent the downlink channel of a UE in a given environment, with a corresponding reduction in the overhead to feedback CSI. A customized beam set, once determined, is configured on a given UE using signalling. A UE that makes channel measurements on a received reference signal uses the channel measurements to obtain a set of beamforming weights for the customized beam set and sends the weights back to the network as CSI.Type: ApplicationFiled: May 15, 2023Publication date: September 14, 2023Inventor: HAMIDREZA FARMANBAR
