csi feedback optimized for fd-pampering

摘要

Improved channel state information (csi) feedback for multi-input, full-size (fd-max) outputs is described. in one aspect, a single csi process is defined that is configured with elevation csi reference signal (rs) ports and an azimuth. a user equipment (eu) will send a precoding matrix indicator report (pmi) ) including a pre-coding matrix indicator (pmi) for azimuth doors and one pmi for elevation doors. one of the pmis is given a low rating. the base station will use both pmis to create a complete channel encoding matrix. in another aspect, a single csi process is configured with a plurality of csi-rs features. It generates channel metering information for each of the csi-rs resources, but only defines a csi report for the base station of a subset of the total number of resources.
