Abstract: Systems, methods, computer-readable medium, and apparatus are disclosed that allow for control information to be provided in an efficient manner during short burst transmission. For example, an apparatus may be configured to receive downlink control information (DCI) that indicates an allocated resource from a base station. The apparatus may also receive data from the base station. The apparatus may generate a cyclically shifted sequence that corresponds to a sequence that is cyclically shifted based on at least one of an ACK or NACK for the received data and a SR. The apparatus may then transmit the cyclically shifted sequence in the allocated resource within one symbol period of a slot of a subframe to the base station. Thus, by transmitting the SR and the ACK/NACK in one symbol, control information for short burst transmissions can be provided in a more temporally efficient manner without adding excessive complexity to the UE.

Abstract: In an aspect, a first BS measures a SRS-P associated with a RTT measurement procedure between a UE and a second base station, and reports measurement information based on the measurement of the SRS-P. In another aspect, a device (e.g., UE, BS, LMF, etc.) obtains the measurement information along with measurement information based on measurements at the UE and the second base station, and determines a positioning estimate of the UE based on the first, second and third measurement information.

Abstract: Aspects of the present disclosure provide techniques for variable spreading factor codes for non-orthogonal multiple access (NOMA). In an exemplary method, a base station assigns, from a first codebook of N short code sequences of length K, a subset of the short code sequences to a number of user equipments (UEs); receives a signal including uplink data or control signals from two or more of the UEs, wherein a first uplink data or control signal is sent using a first subsequence of one of the assigned short code sequences, and a second uplink data or control signal is sent using a second subsequence of one of the assigned short code sequences or using one of the assigned short code sequences; and decodes each uplink data or control signal in the signal based on the assigned short code sequences and subsequences of the assigned the short code sequences.

Abstract: A two stage scrambling design is provided for generating and decoding Resource Spread Multiple Access (RSMA) modulated streams. A User equipment (UE) scrambles each data stream of a set of data streams using a first scrambling sequence to generate a first set of scrambled data streams, and then scrambles the first set of scrambled data streams using a second scrambling sequence to generate a second set of scrambled data streams, wherein the second scrambling sequence is longer than the first scrambling sequence. The UE then transmits the second set of scrambled data streams. A receiving base station determines the first and second scrambling sequences used by the UE and decodes the transmissions received from the UE based on the determined scrambling sequences.

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.
