Abstract:
Disclosed are techniques for determining a location of a user equipment (UE) communicating over a shared communication medium in unlicensed spectrum. In an aspect, the UE receives a unique or distinct positioning reference signal (PRS) configuration for each of a plurality of secondary cells, where each PRS configuration includes a common set of positioning occasions and where the plurality of secondary cells are in contention for the common set of positioning occasions. The UE attempts to measure a PRS for each of the PRS configurations in each positioning occasion and typically measures a PRS for just one PRS configuration in each positioning occasion due to the contention for positioning occasions. The UE reports the PRS measurements and the identities of the measured PRS configurations to a location server which uses the reported data to determine a location for the UE.

Claim (Index 28):
An apparatus for determining a position of a user equipment (UE) communicating over a shared communication medium in unlicensed spectrum, comprising:\n a communication device of a location server configured to:\n send positioning assistance data to the UE, the positioning assistance data comprising a plurality of positioning reference signal (PRS) configurations for a plurality of secondary cells having overlapping coverage areas, each of the plurality of secondary cells having a different PRS configuration of the plurality of PRS configurations, wherein each PRS configuration of the plurality of PRS configurations includes a common set of positioning occasions, and wherein the plurality of secondary cells are in contention for the common set of positioning occasions; and \n receive, from the UE, a first measurement of a first PRS for a first PRS configuration of the plurality of PRS configurations, a second measurement of a second PRS for a second PRS configuration of the plurality of PRS configurations, an identification of the first PRS configuration, and an identification of the second PRS configuration, wherein the first PRS is transmitted by a first evolved NodeB (eNB) for a first secondary cell of the plurality of secondary cells at a first positioning occasion of the common set of positioning occasions, and wherein the second PRS is transmitted by a second eNB for a second secondary cell of the plurality of secondary cells at a second positioning occasion of the common set of positioning occasions; and \n at least one processor of the location server configured to:\n determine the position of the UE based at least in part on the first measurement, the second measurement, the identification of the first PRS configuration, the identification of the second PRS configuration, a location of the first eNB, and a location of the second eNB.
