Abstract: Various aspects described herein relate to techniques for uplink reference signal sequence design in wireless communications systems. A method, a computer-readable medium, and an apparatus are provided. In an aspect, the method includes identifying a set of sequences to include at least a base sequence, a reverse order sequence of the base sequence, a complex conjugate sequence of the base sequence, or a reverse order complex conjugate sequence of the base sequence, and transmitting an uplink reference signal based on at least one of the sequences in the set. The techniques described herein may apply to different communications technologies, including 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Aspects directed towards new radio (NR) transmissions of uplink control information (UCI) are disclosed. In a particular example, a priority is assigned to each of a plurality of UCI components such that the priority is assigned according to at least one of a type or payload size respectively associated with each of the plurality of UCI components. The plurality of UCI components are then transmitted based on the priority respectively assigned to each of the plurality of UCI components.

Abstract: Aspects of the present disclosure provide a scheduling entity in communication with a set of scheduled entities within a wireless communication network. The scheduling entity groups a plurality of tones into uplink clusters, where each uplink cluster includes one or more adjacent tones. In addition, the scheduling entity maps a first set of uplink clusters to a first virtual cluster group (VCG) for an uplink control channel, assigns the first VCG to a first scheduled entity of the set of one or more scheduled entities, provides a first VCG index identifying the first VCG to the first scheduled entity and receives uplink control information from the first scheduled entity on the first VCG over the uplink control channel.

Abstract: Methods, systems, and devices for wireless communications are described that support frequency and time domain multiplexing for low peak-to-average waveforms with multiple streams. A user equipment (UE) may identify sets of symbols associated with different streams (e.g., multiple single-carrier discrete Fourier transform (DFT)-spread waveforms), where each stream may be associated with a low peak-to-average power ratio (PAPR). In some cases, different waveforms may be mapped to subsets of frequency resources through frequency division multiplexing (FDM). The UE may further reduce the PAPR of the multiplexed waveforms by performing time division multiplexing (TDM) across the single-carrier streams, and sets of symbols that are not used by one waveform may be used by another waveform. Frequency domain phase ramps may be applied to align the multiplexed waveforms. Signals included in an uplink transmission according to these techniques may maintain properties similar to single-carrier waveforms, including a low PAPR.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may receive an uplink control configuration indication in a downlink control portion of a first slot. The first slot may include the downlink control portion, a second portion, and an uplink short burst portion. The second portion may be located between the downlink control portion and the uplink short burst portion. The apparatus may configure a physical uplink control channel (PUCCH), on at least one of the second portion or the uplink short burst portion of the first slot, for transmission of first uplink control information (UCI) based at least in part on the uplink control configuration indication. The first UCI may correspond to second UCI to be transmitted in the first slot or a second slot. The apparatus may transmit the first UCI on the configured UCI.

Abstract: Aspects of the disclosure are related to identifying whether an apparatus (e.g. base station access point etc.) is transmitting using a CRS based transmission scheme or a UE RS based transmission scheme. Such detection may be necessary for PDSCH interference cancellation (IC) of a neighboring cell since a UE may not know which transmission scheme is used by the neighboring cell. For instance the UE may know the transmission scheme of the serving cell but the UE may not know the transmission scheme of a neighboring non serving cell. As such aspects of the disclosure provide for a blind detection algorithm to identify or determine a transmission mode or transmission scheme of a neighboring cell to then apply interference cancellation (IC) to an interfering signal received from the neighboring cell.

Abstract: Techniques are described herein for addressing tone misalignment between signals of a first radio access technology (RAT) and signals of a second RAT in a combined signal. In some wireless communications systems, the tones of uplink (UL) signals may be shifted up or down based on the configuration of the particular RAT. If UL signals of the first RAT are not shifted in frequency and UL signals of the second RAT are shifted in frequency, processing the combined signal may include additional processing to account for the mismatch.

Abstract: Techniques are described herein for addressing tone misalignment between signals (215) of a first radio access technology (RAT) and signals (220) of a second RAT in a combined signal (225). In some wireless communications systems, the tones of uplink (UL) signals may be shifted up or down based on the configuration of the particular RAT. If UL signals of the first RAT are not shifted in frequency and UL signals of the second RAT are shifted in frequency, processing the combined signal may include additional processing to account for the mismatch.

Abstract: A method and apparatus for demodulation reference signal (DMRS) communication are described. The method and apparatus include determining a DMRS pattern for at least two multiplexing schemes. In some aspects, the at least two multiplexing schemes may include orthogonal frequency-division multiplexing (OFDM) and single carrier frequency-division multiplexing (SC-FDM). Further, in some aspects, the DMRS pattern may correspond to a continuous tone pattern in each subframe transmitted in accordance with both SC-FDM and OFDM. Additionally, in some aspects, the DMRS pattern may correspond to a comb tone pattern in each subframe transmitted in accordance with both SC-FDM and OFDM. The method and apparatus further include transmitting a DMRS in accordance with at least one of the two multiplexing schemes and based on the DMRS pattern.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to mapping uplink control information (UCI) to resource elements (REs) in a frequency domain with discontinuous physical resource block (RB) allocation. Certain aspects relate to a method including assigning a continuous set of numbers to a plurality of communication resources of a communication channel in order by frequency, the communication channel comprising a plurality of frequency resources and a plurality of time resources, wherein the plurality of communication resources are discontinuous in frequency and assigned to frequency resources associated with indices that are discontinuous. The method further includes mapping uplink control information to the plurality of communication resources based on the continuous set of numbers assigned to the plurality of communication resources. The method further includes one of transmitting or receiving the uplink control information in the plurality of communication resources based on the mapping.
