Original Abstract Submitted
user equipment (ue), an enhanced nodeb (enb) and method of improving positioning accuracy and enabling vertical domain positioning of the ue are generally described. the ue may receive a prsinfo control signal having at least one prs configuration and subsequently a plurality of reference signals (rss). the rss may have a first positioning reference signal (prs) pattern in a first set of prs subframes and a second prs pattern in a second set of prs subframes received prior to a subsequent first set of prs subframes. the rss may have a vertical positioning rs and a lateral positioning rs. the ue may measure prs resource elements (res), each having a prs, in the first and second prs pattern. the ue may transmit a measurement of the prs in the first and second prs pattern. the patterns may enable horizontal and vertical positioning to be determined.
