US 10,856,252 B2 · Device and method to improve horizontal and vertical positioning accuracy

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.

Dependent claims

An apparatus of user equipment (UE) comprising:

processing circuitry arranged to cause a user equipment (UE) to:
decode, from a base station, a radio resource control (RRC) signal, the RRC signal comprising an Observed Time Difference of Arrival (OTDOA) information element (IE) to provide assistance data reference cell information for OTDOA assistance data, the OTDOA IE comprising a PRSInfo IE that provides information related to a Positioning Reference Signal (PRS) configuration in an assistance data reference cell and a PRS field that specifies at least one additional PRS configuration of the assistance data reference cell, the PRSinfo IE comprising an index field that specifies a PRS configuration index IPRS for the PRS configuration and at least one additional PRS configuration;
decode first PRSs based on the PRSinfo IE and second PRSs based on the PRS field;
and
encode, for transmission to the base station, measurements based on the first and second PRSs;
and
a memory to store the measurements.

An apparatus of user equipment (UE) comprising:

a transceiver arranged to communicate with a base station (BS);
and
processing circuitry arranged to:
configure the transceiver to receive a prs-Info control signal comprising first and second Positioning Reference Signal (PRS) configuration indices for a cell of the base station, wherein the first PRS configuration index indicates a periodicity and offset for a first PRS pattern, wherein the second PRS configuration index indicates a periodicity and offset for a second PRS pattern;
configure the transceiver to receive a plurality of Reference Signals (RSs) from the cell, the RSs comprising the first PRS pattern received in a first set of PRS subframes and the second PRS pattern received in a second set of PRS subframes received by the transceiver;
measure PRSs of the first and second PRS patterns;
and
configure the transceiver to transmit a measurement of the PRSs of the first and second PRS patterns to enable horizontal and vertical positioning of the UE to be determined based on the measurements.
