Abstract
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.
