Abstract: Aspects of the disclosure relate to a new radio (NR) single symbol design in which reference signals and data tones are frequency division multiplexed (FDM). In a particular aspect of the disclosure, a different encoding sequence is assigned to each possible value of an information element (IE) such that a minimum distance between encoding sequences corresponding to any pair of possible values is maximized. A symbol corresponding to a particular value of the IE is then transmitted. Here, the symbol is configured according to a sequence selected from a set of sequences corresponding to the particular value of the IE, such that the symbol comprises a plurality of reference signals FDM with a plurality of FDM resource elements.

Abstract: Certain aspects of the present disclosure provide techniques for processing reference and data signals for uplink transmission. A method is provided for wireless communications. The method generally includes obtaining different sets of samples for at least one of: a data signal or a reference signal; spreading the different sets of samples for the at least one data signal or reference signal using separate discrete Fourier transform (DFT) processing blocks; interlacing the spreaded sets of samples by assigning the spreaded sets of samples from each of the separate DFT processing blocks to equally spaced tones; and transmitting the at least one data signal or reference signal on the assigned tones in an orthogonal frequency division multiplexed (OFDM) symbol.

Abstract: The present disclosure provides for adaptive resource management in new radio operations that favors the usage of resources for pilot signals and channel estimation in the transition slots of a slot burst, and the transmission of data in the subsequent slots of the slot burst. A device such as a user equipment (UE) and/or a base station may determine that the UE is operating in a transition state. The device may adapt a first numerology including a first number of symbols per slot used for transmission in the transition slots during the transition state, to a second scaled numerology including a second number of symbols per slot used for transmission in the subsequent slots after the transition state. A ratio of reference signal symbols to data symbol symbols may be greater in the transition slots than in the subsequent slots.

Abstract: A BS may transmit a first signal using a first group of one or more tones, transmit a second signal using a second group of one or more tones, and transmit a third signal using a third group of one or more tones in a GB between the first and second groups of tones. In one example, the transmitting comprises controlling a transmit power of at least one tone of the third group of one or more tones in the GB. The at least one tone of the third group of tones is on a different frequency grid than the first group of one or more tones or the second group of one or more tones. A UE may perform corresponding transmit power control operations for UL transmissions in a GB.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sounding reference signal (SRS) management for a line-of-sight multiple-input multiple-output (LSM) mode. A receiving device may receive a configuration of a persistent or semi-persistent SRS resource set that configures a first number of SRS ports for a full spatial sounding mode. The receiving device may transmit a SRS on a partial sounding resource subset of the SRS resource set, the partial sounding resource subset corresponding to a partial sounding LSM mode. A transmitting device such as a base station may performing phase ramp interpolation for the partial sounding LSM mode to estimate a LSM channel between the base station and the first receiving device.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may transmit, to a second wireless device, a message indicating a capability of the first wireless device to support full-duplex line-of-sight (LOS) multiple-input multiple-output (MIMO) communications. The first wireless device may receive, from the second wireless device, control signaling indicating an uplink channel resource allocated for one or more uplink communications, a downlink channel resource allocated for one or more downlink communications, a first set of LOS MIMO transmission modes for the one or more uplink communications, and a second set of LOS MIMO transmission modes for the one or more downlink communications. The uplink channel resource may at least partially overlap with the downlink channel resource in time, frequency, or both. The first wireless device may communicate the one or more uplink communications and the one or more downlink communications based on the control signaling.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitted may use a closed loop precoder for line-of-sight (LOS) multiple-input multiple-output (MIMO) communications that uses information such as distance feedback or LOS MIMO channel state feedback. A closed loop precoder may be associated with less overhead than a precoder based on full channel knowledge, such as an SVD precoder. A receiver may estimate a channel based on channel state information reference signals transmitted by the transmitter and calculate a spectral efficiency for one or more precoders of a set of precoders associated with the channel for a LOS MIMO mode. The receiver may send feedback to the transmitter that indicates a selected precoder of the set of LOS MIMO precoders based on the calculated spectral efficiencies. The transmitter may precode messages using the reported closed loop precoder.

Abstract: Disclosed are techniques for wireless sensing. In an aspect, a network node detects a collision between at least one wireless communication signal scheduled to be transmitted by the network node and two or more bundled radar reference signals scheduled to be transmitted by the network node, wherein the at least one wireless communication signal is scheduled to be transmitted during a gap between a first radar reference signal and a second radar reference signal of the two or more bundled radar reference signals; performs a collision avoidance operation based on detection of the collision, and transmits the two or more bundled radar reference signals.

Abstract: Methods, systems, and devices for wireless communications are described for a two-step random access channel (RACH) procedure in which uplink random access preamble and message transmission occasions may span multiple transmission slots. Reference signal resources for transmitting a reference signal with a first random access message of the two-step RACH procedure may include at least one symbol in each of the multiple transmission slots. The reference signal resources, reference signal sequence, or both, may be identified based on a particular uplink random access message transmission occasion, random access preamble transmission occasion, random access preamble sequence configuration, or any combinations thereof.
