Method And Apparatus for UE Positioning in LTE Networks
Methods and apparatuses are provided for user equipment positioning in networks. An example method includes computing a location of a user equipment (UE). The computing includes joint scheduling of UL subframes and receiving a Up Link Positioning Reference Signal (UL-PRS). The computing is performed by a network equipment that serves at least one cell site. The UL-PRS is received in a known subframe. The computing may also include estimating an arrival time the UL-PRS from the UE for a plurality of cell sites. In another embodiment, the computing includes determining a one-way delay between
1 . A method comprising:
computing a location of a user equipment (UE) wherein said computing includes
joint scheduling of UL subframes; and
receiving a Up Link Positioning Reference Signal (UL-PRS).
2 . The method of claim 1 wherein said computing is performed by a network equipment that serves a cell.
3 . The method of claim 1 wherein the UL-PRS is received in a known subframe.
4 . The method of claim 1 wherein said computing comprises:
estimating an arrival time for a plurality of cell sites.
5 . The method of claim 4 wherein said computing further comprises:
determining a one-way delay between the UE and the plurality of cell sites; and
determining the location via tri-lateration.
6 . An apparatus comprising:
a memory for storing a plurality of instructions;
a processor for executing said instructions, said instructions when executed computing a location of a user equipment (UE) wherein said computing includes
joint scheduling of UL subframes; and
receiving a Up Link Positioning Reference Signal (UL-PRS).
