    Abstract: Methods, systems, and devices for wireless communications are described. For instance, the described techniques support resource offset mapping for multiplexing. Resource offset mapping may refer to the mapping of frequency-domain symbols to different subsets of resources that are offset from each other or separated by gaps. For instance, a first wireless device may map a first set of frequency-domain symbols to a first subset of subcarriers and a second set of frequency-domain symbols to a second subset of subcarriers. A lowest subcarrier of the second subset of subcarriers may be separated by an offset or a gap from a highest subcarrier of the first subset of subcarriers. As a result, at least some distortion experienced on subcarriers in the gap may not spread to other subcarriers, and the reliability and throughput of communications between the first wireless device and a second wireless device may improve.

    Abstract: Methods, systems, and devices for wireless communications are described. A non-coherent modulation configuration may be selected for a transmission of a set of data based on a radio frequency spectrum band used for the transmission. After selecting the non-coherent modulation configuration, the set of data may be modulated using a differential phase shift keying modulation technique. After selecting the non-coherent modulation configuration, a set of frequency-domain symbols may be generated from the set of modulated symbols using a discrete Fourier transform. The set of frequency-domain symbols may be mapped to a set of subcarriers, and a time-domain waveform may be generated from the mapped set of frequency-domain symbols, yielding a time-domain waveform. The time-domain waveform may be transmitted over the radio frequency band.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a configuration indicating a set of resources for a reference signal to track an in-phase and quadrature-phase imbalance of the UE. The set of resources may include a first subset of resources for transmitting the reference signal and a second subset of resources for a mirror image signal that is generated during upconversion of the reference signal. The UE may upconvert the reference signal to a set of subcarriers corresponding to the first subset of resources and transmit the upconverted reference signal on the first subset of resources. The base station may receive the reference signal and the mirror image signal and determine a signal adjustment for communications with the UE based on the received reference signal and the received mirror image signal.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine one or more demodulation reference signal (DMRS) scrambling sequences using a low peak-to-average power ratio (PAPR) sequence generator, each corresponding to a respective port of one or more ports, the one or more ports being associated with a downlink multiple input multiple output (MIMO) communication, wherein the downlink MIMO communication is a discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM)-based communication. The UE may receive the downlink MIMO communication including a DMRS according to an intra-slot DMRS pattern that indicates one or more time domain multiplexed symbols, each being at least partially allocated with at least one DMRS scrambling sequence of the one or more DMRS scrambling sequences. Numerous other aspects are described.
