METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING POSITIONING REFERENCE SIGNAL IN WIRELESS COMMUNCATION SYSTEM
An apparatus and method of processing a positioning reference signal are disclosed. In some embodiments, the method includes determining a narrow-band (NB) positioning reference signal (PRS) bitmap indicating a pattern selecting NB PRS subframes, wherein each NB PRS subframe comprises an NB PRS for positioning an NB user equipment (UE), transmitting, to the NB UE, NB PRS configuration information for the NB UE, the NB PRS configuration information comprising the NB PRS bitmap, determining, by a reference cell and based on the NB PRS bitmap, NB PRS subframes of the reference cell, mapping, by the reference cell, a first NB PRS in the NB PRS subframes of the reference cell, and receiving, from the NB UE and in response to the first NB PRS, a reference signal time difference (RSTD) measurement.
1 . A method comprising:
receiving, by a wireless user device and via an antenna, narrow-band (NB) positioning reference signal (PRS) configuration information comprising an NB PRS bitmap indicating a pattern associated with NB PRS time resources, wherein at least one of the NB PRS time resources comprises an NB PRS for positioning the wireless user device;
receiving, via first radio frames of a cell and based on a plurality of repetitions of the NB PRS bitmap, a first NB PRS mapped in at least one of first NB PRS time resources of the cell, wherein an NB PRS muting indicator indicates that the first radio frames of the cell are not muted;
generating, based on the first NB PRS, a reference signal time difference (RSTD); and
transmitting the RSTD.
