US 10,383,080 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:
decode, from an enhanced NodeB (eNB), a plurality of Reference Signals (RSs), the RSs comprising a first Positioning Reference Signal (PRS) pattern received in a first set of PRS subframes and a second PRS pattern received in a second set of PRS subframes received by the transceiver prior to a subsequent first set of PRS subframes;
measure PRSs of the first and second PRS pattern;
and
generate, for transmission to the eNB, a measurement of the PRSs of the first and second PRS pattern;
and
a memory to store instructions for the measurement of the PRSs of the first and second PRS pattern,
wherein the RSs further comprise a vertical positioning RS associated with a different antenna port than a lateral positioning RS, and
wherein the vertical positioning RS is used to determine a vertical position of the UE and the lateral positioning RS is used to determine a lateral position of the UE.

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a user equipment (UE) to configure the UE to communicate with an enhanced NodeB (eNB), the one or more processors to configure the UE to:

receive, from the eNB, a prsInfo control signal comprising at least one PRS configuration, and subsequently receive from the eNB a plurality of Reference Signals (RSs), the RSs comprising a first Positioning Reference Signal (PRS) pattern received in a first set of PRS subframes and a second PRS pattern received in a second set of PRS subframes received by the transceiver prior to a subsequent first set of PRS subframes, the RSs comprising a vertical positioning RS and a lateral positioning RS, the vertical positioning RS used to determine a vertical position of the UE and the lateral positioning RS used to determine a lateral position of the UE;
measure PRS resource elements (REs), each comprising a PRS, in the first and second PRS pattern;
and
transmit a measurement of the PRS in each of the first and second PRS pattern to the eNB.
