Abstract: Various aspects directed towards generating a reference signal for pi/2-binary phase shift keying (BPSK) modulation are disclosed. In an example, a pi/2-BPSK sequence is selected from a plurality of candidate sequences. A reference signal is then generated based on the selected pi/2-BPSK sequence such that the reference signal is associated with a transmission of data modulated according to a t/2-BPSK modulation.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus generating sequences and mapping cyclic shifts of the sequences to hypotheses for short burst transmissions, for example, in new radio (NR) technologies. An exemplary method includes selecting a computer generated sequence (CGS), from a plurality of CGSs; determining, based on different values of uplink control information (UCI) and a first shift index assigned to the transmitter, a shift to apply to the CGS; and transmitting the selected CGS, with the determined shift applied, in a short physical uplink control channel (PUCCH) to indicate the UCI.

Abstract: Aspects of the present disclosure provide techniques for handling power transitions in transmissions in new radio (NR) devices. An exemplary method includes changing from using a first transmit power during a first portion of a transmission to a second transmit power during a second portion of the transmission, and taking action to mitigate a potential phase coherence loss associated with the changing from the first transmit power to the second transmit power.

Abstract: Various aspects described herein relate to techniques for timing control with filtering in orthogonal frequency division multiplexing (OFDM)-based wireless communications systems. In an aspect, the method includes determining whether time-domain filtering or frequency-domain filtering is used for a transmission signal waveform, and identifying a time delay based on a determination that the time-domain filtering is used for the transmission signal waveform. The method further includes applying a timing correction based on the identified time delay. The techniques described herein may apply to different communications technologies, including 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to an RE mapping rule for UCI piggyback on PUSCH. For example, a method may include determining a set of uplink resources to use for transmitting acknowledgment (ACK) information in a physical uplink shared channel (PUSCH) transmission, wherein the determination is based at least in part on a payload size of the ACK information, and transmitting the ACK information using the determined set of uplink resources.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for short uplink burst designs. In some cases, one sequence, from a plurality of sequences, may be transmitted in multiple tones of at least one short burst symbol conveying at least one bit of information. The plurality of sequences may have the same values at a first set of common tone locations for demodulation reference signals (DMRS) and groups of sequences from the plurality of sequences may be identified, each sequence in a group having a second set of common tone locations for DMRS.

Abstract: Aspects of the disclosure relate to communication systems, apparatus and methods which enable or support configuring timing advance in a radio access network. The method includes defining a timing advance configuration for a radio access network that employs a modulation scheme with scalable numerology, determining timing advance parameters consistent with the timing advance configuration for a user equipment (UE) that is in communication with the radio access network, and transmitting the timing advance parameters to the UE during an initial access procedure involving the UE or while the UE is in a connected state in the radio access network. The timing advance configuration may be defined to accommodate a numerology used by the radio access network.

Abstract: The present disclosure generally relates to methods, and apparatus for implementing the methods, for using sequence based uplink control information in 5G New Radio wireless communications. The method may include a user equipment (UE) may construct a signal based at least on resource assignment information received from a base station. The resource assignment information received by the UE may indicate frequency resources, a base sequence index, and a shift index. In a non-limiting example, the resource assignment information may include frequency resource assignment information related to one or more clusters. In implementations in which the frequency resource information includes a plurality of clusters, each of the plurality of clusters use a different base sequence and may use the same or different cyclic shifts. These sequences may be multiplexed in a non-orthogonal manner. The UE may use the resource assignment information to transmit the constructed signal to the base station.

Abstract: Aspects of the present disclosure implement techniques for power control management between the base station and the UE to support multiple waveforms and services. In one example, the power control management system may implement independent power control loops for each waveform and service (e.g., eMBB, uRLLC, etc.) supported by the wireless communication system. For example, the base station may transmit a first power control command to a UE for first waveform (e.g., CP-OFDM) or service (e.g., eMBB) and a second power control command to the UE for the second waveform (DFT-OFDM) or service (e.g., uRLLC). Features of the present disclosure may also implement techniques that allow the base station to transmit a single power control command for configuring the power control for a plurality of waveforms or services. Upon receiving the power control commands, the UE may configure the transmission power for uplink traffic based on the power control commands.
