FIG5 depicts a simplified transmission diagram of an exemplary embodiment in accordance with this invention. As shown, UE 210 is served by eNB 220. At time 510, LE 440 instructs the eNB 220 to order the UE 210 to transmit a signal for locationing purposes. These instructions may include an assignment of signal characteristics. Alternatively, eNB may determine the signal characteristics for the signal and inform the LE accordingly (not shown). As an additional alternative, the LE 440 may instruct the UE 210 directly, for example, where the LE 440 is embodied in the eNB 220.

['11. An evolved Node B (eNB) comprising: a transmitter and a processor operable to transmit a radio resource control, RRC, signal including uplink sounding reference signal, UL SRS, configuration information to at least one user equipment, UE; and the transmitter and the processor further operable to transmit a semi-persistent scheduling, SPS, message to the at least one UE to initiate transmission of UL SRSs by the at least one UE; and the processor and a receiver operable to receive UL SRSs in a time and frequency pattern based on the UL SRS configuration information and the SPS message from the at least one UE.']
