Abstract: Various aspects described herein relate to distinguishing frequency shift keying (FSK) signals transmitted by each user of multiple users in a wireless communications system. One or more symbols for transmitting in an FSK-modulated signal can be obtained by a user. The one or more symbols can be encoded based on a tone location assignment corresponding to a unique spreading code associated with the user. Quadrature amplitude modulation (QAM) and/or phase-shift keying (PSK) can be performed over at least one tone associated with the encoded symbols. Each user can transmit the encoded symbols to a receiving entity, where the receiving entity can decode each symbol received from the plurality of users to produce a distinguishable symbol for each user based on the unique spreading codes associated with each user.

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: Certain aspects relate to methods and apparatus for a flexible transmission unit and acknowledgement feedback timeline for low-latency communication. As described herein, a UE may receive, within a subframe a first portion of a downlink control region scheduling at least a first data unit, wherein the subframe comprises at least two TTIs and wherein the subframe comprises the downlink control region, a data region, and an uplink control region, receive the first data unit in a first TTI of the data region, receive a second data unit in a second TTI of the data region, and separately acknowledge receipt of the first and second data units. According to aspects, the acknowledgment for the first data unit may occur in the same subframe as the transmission of the first data unit. A BS may perform corresponding operations.

Abstract: Disclosed are techniques for determining a position of a user equipment (UE). A differential round-trip-time (RTT) based positioning procedure is proposed to determine the UE position. In this technique, the UE position is determined based on the differences of the RTTs between the UE and a plurality of base stations. The differential RTT based positioning procedure has much looser inter-gNodeB timing synchronization requirements than the OTDOA technique and also has much looser group delay requirements than traditional RTT procedures.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a positioning reference signal configuration of a base station. The UE may determine, based on the positioning reference signal configuration, a reference point within a carrier bandwidth of a component carrier and a frequency domain allocation for a positioning reference signal relative to the reference point. The UE may transmit the positioning reference signal or measure the positioning reference signal based on the frequency domain allocation.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for reinforcement-learning-based compressed sensing. An observed signal tensor comprising a plurality of elements is accessed, and a subset of elements of a sensing matrix is generated based on processing, from among the plurality of elements, a subset of elements of the observed signal tensor using an acquisition neural network. A subset of elements of a reconstructed signal tensor is generated based on processing a second subset of elements of the observed signal tensor and the subset of elements of the sensing matrix using a reconstruction neural network. At least the first subset of elements of the reconstructed signal tensor is output.

Abstract: Certain aspects of the present disclosure provide techniques for improved machine learning. A data tensor is generated as output from a layer of a neural network. A first subset of the first data tensor and a second subset of the first data tensor are generated using a tensor splitting operation. The second subset of the first data tensor is stored, and the first subset of the first data tensor is provided to a subsequent layer of the neural network. One or more parameters of the layer of the neural network are refined based at least in part on the stored second subset of the first data tensor.

Abstract: Aspects of the present disclosure provide a wireless device that communicates with another wireless device utilizing self-contained subframes. The wireless device communicates with a scheduling entity utilizing a plurality of self-contained subframes that include a first subframe and a second subframe. Each of the self-contained subframes includes an uplink (UL) portion and a downlink (DL) portion. The wireless device further receives DL control information from the scheduling entity in the DL portion of the first subframe, and transmits UL data that includes a plurality of reference signal bursts to the scheduling entity in the UL portion of the first subframe. The plurality of reference signal bursts are uniformly spaced in at least a portion of the UL portion of the first subframe.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for training and using machine learning models to estimate a layout of a spatial area. An example method generally includes estimating a representation of a channel using a machine learning model trained to generate the estimated representation of the channel based on a location of a transmitter in a spatial environment, a location of a receiver in the spatial environment, and a three-dimensional representation of the spatial environment. One or more actions are taken based on the estimated representation of the channel.

Abstract: Disclosed are techniques to determine a position of a user equipment (UE). In an aspect, the UE receives a plurality of positioning reference signals (PRS) from a plurality of cells. The UE determines a plurality of time of arrivals (TOA) of the plurality of PRSs, and prunes the plurality of TOAs based on the plurality of PRSs. The UE then derives a time difference of arrival (TDOA) vector from the pruned TOAs. The TDOA vector includes multiple TOA related measurements of multiple cells. The UE prunes the TOAs such that the cells represented in the TDOA vector are sufficiently geographically dispersed to determine the position of the UE at least in 2D.
