This disclosure relates to techniques for synchronization signals. The synchronization signal comprise a primary synchronization signal (PSS) generated based on a PSS sequence and a secondary synchronization signal (SSS) generated based on an SSS sequence. The SSS sequence may be generated based on a first sequence corresponding to a first cyclic shift and a second sequence corresponding to a second cyclic shift. The first cyclic shift and the second cyclic shift are associated with a Cell ID. The PSS sequence may be generated based on one of the first and the second sequences.

Devices, systems and methods for a fifth generation (5G) or new radio (NR) system comprising multiplexing, by a gNodeB (gNB), a physical broadcast channel (PBCH) and an associated demodulation reference signal (DMRS) in a time division multiplexing (TDM) manner; and transmitting, by the gNB, the PBCH by employing a Discrete Fourier Transform-spread-orthogonal frequency-division multiplexing (DFT-s-OFDM) waveform and its associated DMRS.

In an ultra-wideband (UWB) communication system comprising a pair of UWB transceivers, methods for securely performing channel sounding. In a first GCP Sync method, a pre-determined set of Golay Complementary Pairs is added to an 802.15.4a frame. In a second CLASS method, a cyphered low auto-correlation sum set is added to frame. In a third LCSSS method, a low cross-correlation sidelobe sum set is added to the frame. In general, these methods are adapted to transmit a pseudo-randomly generated codeset which may have inherent sidelobe distortions, and then, in the receiver, to compensate for this, and any channel-induced, distortion by selectively modifing the cross-correlation codeset.

Facilitating port specific downlink control channel design for advanced networks (e.g., 4G, 5G, and beyond) is provided herein. Operations of a system can comprise receiving a first indication related to a quantity of demodulation reference signal ports and a second indication related to a code division multiplexing group associated with a mobile device. The operations can also comprise, based on the code division multiplexing group and the demodulation reference signal ports, facilitating a transmission of an adaptive downlink control channel structure of a downlink control channel that comprises a demodulation reference signal sequence initialization.

In the multiple short sequence based SRS, multiple items of sequence data having a short sequence length corresponding to a partial band are used for transmitting SRS in discontinuous bands. In the multiple short sequence based SRS, a terminal specifies a frequency domain to be used for transmitting a reference signal using predetermined sequence data, applies a phase shift index associated with the specified frequency domain to the reference signal, and transmits the reference signal to which the phase shift index is applied by using the specified frequency domain.

Technology for a Next Generation NodeB (gNB) operable to encode a primary synchronization signal for transmission to a user equipment (UE) is disclosed. The gNB can identify a sequence d(n) for a primary synchronization signal. The sequence d(n) can be defined by: d(5 n)=1.2s(n), where s(n) is a maximum run length sequence (msequence) and s(n) is provided as s(n+7)=(s(n +4)+s(n)) mod 2, where 0.n.127. The gNB can generate the primary synchronization signal based on the sequence d(n). The gNB can encode the primary synchronization signal for transmission to the UE.

Techniques, schemes and examples pertaining to sequence design for synchronization and device identification in mobile communication systems are described. A processor of an apparatus generates a set of root sequences and also generates a set of signature sequences from the set of root sequences. The processor then transmits a signal comprising one or more of the signature sequences to a receiving device via a wireless channel. Each signature sequence of the set of signature sequences identifies the apparatus.
