Abstract
A Long Term Evolution Advanced (LTE-A) location server, user equipment (UE) and evolved Node-B (eNB) are generally described. Information may be transmitted to the UE from the location server. The transmission may be triggered by the location server or another entity requesting the UE location. The information may permit the UE to receive a discovery reference signal (DRS) from at least one eNB. The information may contain an indication of measurements to be performed using the DRS. The UE may measure Reference Signal Received Power (RSRP) or Reference Signal Time Difference (RSTD) of the DRS. The UE may send the measurement information to the location server where the UE location is estimated. The UE location may be based on measurements of the DRS and a positioning reference signal (PRS) from one or more eNBs to obtain the Observed Time Difference of Arrival (OTDOA) or Enhanced Cell ID (ECID).
