    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to receive a plurality of combined signals. Each combined signal may be on a tone of a plurality of tones. The apparatus may be configured to determine a first pilot signal on a first tone of the plurality of tones. The apparatus may be configured to generate an interference-reduced signal for the first tone by canceling the determined first pilot signal from a first combined signal on the first tone.

    Abstract: Aspects of the disclosure relate to methods and apparatus of time-domain multiplexing (TDM) for reference signals (RS) and data using a modified cyclic prefix. A reference signal (RS) and data are multiplexed either in a single symbol or in two time consecutive symbols that respectively including the RS and data. The cyclic prefix (CP) is added to the single symbol using a portion of the RS or to a first symbol of the two time consecutive symbols using a portion of the RS. The CP may be copied from the RS or the end of the symbol, but not the data, in a manner that affords a virtual Time Division Multiplexing (TDM) of the RS and data before discrete Fourier transform (DFT) spreading is performed in a transceiver to provide lower peak to average power ratios and no Inter-symbol interference.

    Abstract: Signaling strategies for an advanced receiver with interference cancellation (IC) and suppression is discussed. Upon enablement of an advanced interference cancellation procedure according to the disclosure, transmitters within the enabled area transmit according to transmission restriction configurations that provide transmission limits based on either frequency, time, or scheduling. The restrictions on the transmitters reduces the complexity of processing by neighboring advanced receivers for cancellation of interference from the restricted transmitters. At the advanced receiver, transmission information, such as scheduling, reference signal (RS), resource block (RB) allocation, and the like, may either be determined through blind detection or received directly through signaling. The advanced receiver may use this transmission information associated with each interfering signal to detect, decode, and subtract the interfering signals from the received transmissions.

    IPC: H04L27/26

    Abstract: Methods, systems, and devices for wireless communications are described. Pre-discrete Fourier transform (DFT) time-domain spreading codes may be applied for UE multiplexing for uplink control information (e.g., over shared resources of an uplink slot). For example, a moderate number of UEs may be multiplexed within the same slot by having each UE spread modulation symbols before DFT-spreading by different spreading code. For orthogonality across UEs, the pre-DFT spreading codes may be selected as orthogonal cover codes (OCCs). The spreading sequences can be generated from a set of any orthogonal sequences or generated from unitary matrices. In some cases, orthogonality in the time domain may be kept as well as a frequency division multiplexed (FDM) structure in the frequency domain. For such property, a Fourier basis OCC design may be used. In some other examples, a Hadamard matrix based OCC design may be used.

    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: Wireless communications systems and methods related to improve control reporting latency are provided. A wireless communication device receives, from a first link in a first time interval, first control information associated with a second link and the first time interval. The wireless communication device transmits, via the second link in the first time interval, a control report associated with the second link based on a report configuration that is independent from the first control information. The report configuration is associated with a waveform type. The wireless communication device receives, from the first link in a second time interval following the first time interval, second control information that is dependent on the control report. The report configuration includes a power headroom (PHR) report configuration. The PHR report configuration includes a reference PHR report configuration. The PHR report configuration includes a delayed PHR report configuration.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured with a transmission stream processor used to maintain a lower peak-to-average power ratio (PAPR) for uplink transmissions. In some cases, a UE may map modulated symbols of different signals (or waveforms) to interleaved subsets of frequency resources, and this form of frequency division multiplexing (FDM) may increase the PAPR of an uplink transmission. To reduce the PAPR of uplink transmissions, a transmission stream processor at the UE may support techniques for phase ramping modulated symbols in the time domain prior to mapping the symbols to the frequency resources. These techniques may help to ensure that the signals to be included in an uplink transmission are aligned in such a way that the PAPR of the uplink transmission is reduced.
