  • LBS Location Based Services
  • GPS Global Positioning System
  • GLONASS GLObal NAvigation Satellite System
  • GNSS-based LBS only works well when the UE has a good line-of-sight to the satellite. Where the satellite signals are blocked, GNSS will not work. GNSS thus fails in dense urban environments and inside buildings.
  • the FCC is now proposing to extend E91 1 to automatically supply location information to dispatchers when calls are received from indoor locations.
  • the FCC requires that vertical location information (z axis) be provided within 3 meters of the caller for 67% of indoor locations (increasing to 80% in five years). Since Radio Access Technology (RAT) signals have higher received power relative to GNSS signals, RAT-based location services are starting to receive higher attention in the industry to meet these requirements. GNSS alone is insufficient to satisfy the new FCC requirements.

  • the beam information, along with time of arrival measurements, is used to determine the position or improve the position accuracy of the UE. Measurements taken from multiple communication links between the UE and the eNB enable the position of the UE to be obtained more accurately
  • LBS Location Based Services
  • Some LBS employ multilateration, a navigation technique based on measuring the difference in distance to two objects at known locations that broadcast signals at known times. The resulting locations form a hyperbolic curve. Additional measurements taken with additional objects cause a second hyperbolic curve, which intersects with the first hyperbolic curve, resulting in a fix of the location.

  • GPS Global Navigation Satellite Systems
  • Most mobile devices include an integrated GNSS receiver. At least four satellites, each with an unobstructed line-of-sight to the UE, enable estimation of the UE's position.
  • GNSS receiver GPS chip
  • the UE uses its GPS chip (GNSS receiver) to make a connection to the satellites. GPS operations are time-consuming and are unavailable in dense urban environments or inside buildings.
  • Assisted GNSS improves the receipt of location information by the UE because the serving eNB makes the initial connection with the satellites and stores the information obtained.
  • the eNB then provides the data to the GNSS receiver.
  • This data includes Almanac and/or Ephemeris data.
  • Almanac data contains coarse orbital parameters from all global navigation satellites, and is updated infrequently.
  • Ephemeris data uses clock correction to obtain very precise location information, which is broadcast by each satellite every 30 seconds.
  • the position calculations, based on the assistance data can be made by other network entities besides the UE. Nevertheless, A-GNSS is problematic inside buildings and in dense urban environments, due to the unavailability of a line- of-sight satellite signal at the UE.

  • the PRS enable the terminal (UE) to perform measurements on one or more LTE cells (eNBs) to estimate the geographical position of the terminal.
  • eNBs LTE cells
  • PRS are defined by bandwidth, offset, duration (the number of consecutive subframes), and periodicity.
  • the PRS are configured to the UE via higher layer signaling by providing these characteristics: the carrier index where PRS is transmitted, the PRS bandwidth, the number of consecutive subframes for PRS transmissions, PRS transmission periodicity/subframe offset, and the PRS muting sequence.
  • the PRS bandwidth is smaller than the system bandwidth, and PRS are mapped around the carrier frequency. Typically, no PDSCH is transmitted in a subframe where PRS are configured. PRS can be muted to reduce inter-cell interference as needed.
  • A-GNSS described above predates the implementation of positioning reference signals, but PRS are used for both OTDOA and E-CID location services, as described below.
  • OTDOA Observed Time Difference of Arrival
  • OTDOA is similar to GPS and other A-GNSS-based location services, but, instead of taking measurements from satellites, the UE obtains measurements from eNBs in its proximity, including the base station communicating with the UE (known as its serving eNB), as well as neighboring eNBs.
  • the UE measures the time difference between PRS transmitted by its serving eNB, and those of at least two neighboring eNBs.
  • the UE calculates a Reference Signal Time Difference (RSTD) by measuring a time difference between the PRS of a neighboring cell and the PRS of its serving cell; a second time difference is measured between the PRS of a second neighboring cell and the PRS of its serving cell.
  • RSTD Reference Signal Time Difference
  • the network knows the location of the eNBs and this enables the UE location to be obtained, relative to the eNBs, using these RSTDs.
  • FIG. 3 illustrates the OTDOA positioning technique.
  • a UE 50 is located closest to its serving eNB 40, but neighboring eNBs 40A and 40B are within range of the UE.
  • the UE calculates a first RSTD (RSTD N i ) by measuring the time difference between receipt of PRS from neighboring cell A (TRX NA) and the serving cell (T R x_ S erving); the UE calculates a second RSTD (RSTDN2) by measuring the time difference between receipt of PRS from neighboring cell B (T RX _ N B) and the serving cell (T R x_ S erving)- Both measurements are reported to a location server, which calculates the UE position based on the received measurements, RSTDNI and RSTDN2-
  • the network assists the UE by providing the relative transmission time differences of each neighbor cell relative to the serving cell.
  • Location servers in the network know the exact position of each eNB transmit antenna, and can provide candidate neighboring cells to the UE, thus limiting the search space and increasing the speed of measurements taken.

  • additional measurements can be obtained as follows:
  • the measurements help to find the location of the UE within the cell with more precision.
  • the measurements may consist of a Reference Signal Received Power (RSRP), a Time Difference of Arrival (TDOA) and the measurement of the Timing Advance (TA), or a Round Trip Time (RTT), from the serving eNB.
  • RSRP is the average power of Resource Elements (REs) that carry PRS over the entire bandwidth.
  • TDOA is obtained by measuring the time of arrival of synchronized signals (such as the PRS) at physically separate locations.
  • TA is the length of time a signal takes to reach the eNB from the UE.
  • Commonly used TA measurements are type 1 , summing the eNB and UE receive-transmit time differences, and type 2, a measurement taken by the eNB during a UE Random Access procedure.
  • the TA type 1 measurement corresponds to the RTT.
  • type 1 TA measurements for example, the sum of the receive-transmit timing difference at the eNB (positive or negative value) and the receive- transmit timing difference at the UE (always a positive value) is taken. The measurement is reported to the location server, where the distance between the UE and the eNB is half the RTT multiplied by the speed of light.
  • the position of the UE is obtained by estimating the distance of the UE from the serving eNB (whose location is known by the network).
  • the estimate measures a RSRP, a TA, or an RTT, from the serving eNB.
  • the first E-CID option results in a circle around the eNB (coarse position).
  • the RSRP, TA, or the RTT from each of three eNBs is measured (where the location of each eNB is known to the network).
  • the position accuracy is much finer than a circle around the eNB and is instead a point within the cell.
  • the third option is distinguishable from the first two in that measurements are taken by the eNBs, rather than the UE.
  • AoA Angle-of Arrival
  • Each of the two or three eNBs estimates the direction from which the UE is transmitting using a linear array of equally spaced antenna elements.
  • the PRS received from the UE at any two adjacent elements are phase rotated by an amount that depends on the angle of arrival, the carrier frequency, and the element spacing.
  • the measurements are taken by the UE and based on RSRP, TA, or RTT estimations.
  • the measurements are taken directly by the eNB.
  • FIG 4 is a simplified diagram illustrating how E-CID is improved by using multiple measurements. For simplicity, just one base station is shown. Where basic E-CID is used, the position of all UEs in the cell area is coarsely known, and is essentially a circle around the eNB; with E- CID plus RTT, UEs that are a measured distance from the eNB are located; with E-CID plus RTT plus AoA, the position of the UE can be obtained with the most precision.
