Disclosed are systems, methods, and non-transitory computer-readable media for improved data transmissions using puncturing and binary sequences. A receiving device receives a sequenced data input that includes a set of individual values and performs a puncturing of the sequenced data input, yielding a punctured sequenced data input. The receiving device calculates correlation values for the punctured sequence data input and a set of predetermined data outputs. The receiving device determines whether any of the resulting correlation values exceeds a threshold correlation value. In response to determining that the correlation value calculated based on one of the predetermined data outputs exceeds the threshold correlation value, the receiving device determines that the sequenced data input corresponds to the predetermined data output.
Length-six computer generated sequences (CGS) for uplink low peak-to-average power ratio (PAPR) demodulation reference signals (DMRS)
An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for DMRS processing in an NR network, the processing circuitry is to decode higher layer signaling, the higher layer signaling to indicate whether transform precoding is enabled and to indicate a modulation scheme for a physical uplink shared channel (PUSCH) if transform precoding is enabled. A set of low Peak-to-Average-Power-Ratio (PAPR) base sequences of length-6 is generated. A reference signal sequence is generated as a demodulation reference signal (DMRS) using the set of low-PAPR base sequences, based on the modulation scheme if transform precoding is enabled by the higher layer signaling, the modulation scheme being a π/2-binary phase-shift keying (BPSK) modulation scheme. Mapping of the DMRS to physical resources for transmission using the PUSCH is performed.
