    Abstract: Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method for wireless communication. The method includes determining at least one RS pattern for allocating a reference signal on an uplink channel and a downlink channel based on one or more transmission factors for transmitting the reference signal, wherein at least a portion of the at least one RS pattern is the same for the uplink channel and the downlink channel. The method further includes transmitting the reference signal using the determined RS pattern.

    Abstract: The apparatus may be a transmitter. The transmitter including a modulator configured to modulate a binary input sequence with a particular modulation coding scheme to generate a modulated input signal. The transmitter also including a spectral shaping circuit configured to spectral shape a first version of the input signal to generate a spectral shaped signal. The spectral shaping circuit also includes a FIR filter configured to lower peak-to-average power ratio of the spectral shaped signal. The transmitter also includes a discrete Fourier transform circuit configured to discrete Fourier transform a second version of the input signal to generate a discrete Fourier transformed signal. The modulated input signal is one of the first version of the input signal or the second version of the input signal and the spectral shaped signal is another of the first version of the input signal or the second version of the input signal.

    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: Various aspects are provided for dynamic configuration of common uplink bursts. For example, the described apparatus and methods include receiving, at a user equipment (UE), an indicator of a length of a common uplink burst from a gNB, configuring the common uplink burst having the length as identified by the indicator, and transmitting, from the UE, the common uplink burst to the gNB.

    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: Techniques for supporting UE operation with enhanced uplink are described. A UE may select a first signature from a first set of signatures available for random access for enhanced uplink, generate an access preamble based on the first signature, and send the access preamble for random access while operating in an inactive state. The UE may receive an acquisition indicator (AI) for the first signature on an acquisition indicator channel (AICH) from a Node B. The UE may use a default enhanced dedicated channel (E-DCH) resource configuration for the first signature if the AI has a first predetermined value. The UE may determine an E-DCH resource configuration allocated to the UE based on an extended acquisition indicator (EAI) and a second signature if the AI has a second predetermined value. In any case, the UE may send data to the Node B using the allocated E-DCH resource configuration.
