Abstract: 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.

Abstract: A method, apparatus, and system for transmitting and receiving a physical broadcast channel (PBCH) are provided. A base station may perform a first scrambling process on PBCHs in a time period before a channel coding, and perform a second scrambling process after the channel coding. PHCH payloads and PBCH DMRS may provide information bits to be used in the scrambling processes. A wireless user device may receive one or more PBCHs transmitted from the base station.
