摘要： Provided is a method and apparatus for receiving a reference signal. A wireless user device may determine, based on a synchronization signal (SS) block index and based on an index associated with a time interval, an initialization value associated with a reference signal for a physical broadcast channel (PBCH). The wireless user device may receive, based on the initialization value and based on a frequency domain shift value, the reference signal via at least one resource element (RE). The reference signal may be mapped, based on the frequency domain shift value, to the at least one RE. The wireless user device may receive the PBCH.

摘要： 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.

摘要： 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.

摘要： Exemplary embodiments provide a method and apparatus for transmitting a synchronization signal for Device-to-Device (D2D) communication in a wireless communication system. With respect to a D2D synchronization source to transmit a synchronization signal for D2D communication, the method includes: generating a D2D Synchronization Signal (D2DSS); and transmitting, by a synchronization source, the D2DSS to a D2D reception (Rx) UE, wherein the D2DSS includes a Primary D2D Synchronization Signal (PD2DSS) generated based on information associated with the synchronization source.

摘要： Methods, apparatuses, and systems described herein generally relate to a reference signal generation and mapping. For example, a method comprises determining a first set of antenna ports for a demodulation reference signal (DM-RS) transmission; determining, based on the first set, a frequency index associated with four adjacent resource elements, wherein the four adjacent resource elements correspond to two adjacent symbols in a time axis and to two adjacent subcarriers in a frequency axis; generating, based on a first orthogonal cover code and a second orthogonal cover code, a DM-RS associated with the first set of antenna ports; and transmitting, via a mapping to the four adjacent resource elements, the DM-RS associated with the first set of antenna ports.
