Abstract: Monostatic radar (314) with progressive length transmission may be used with half-duplex systems or with full-duplex systems to reduce self-interference. The system transmits a first signal (350) for a first duration (302) and receives a first reflection (324) of the first signal from a first object (316) during a second duration (304). The system transmits a second signal (352) for a third duration (306) longer than the first duration and receives a second reflection (328,330) of the second signal from a second object (318) during a fourth duration (308). The system calculates a position of the first object and the second object based on the first reflection and the second reflection. The first signal, first duration, and second duration are configured to detect reflections from objects (316) within a first distance of the system. The second signal, third duration, and fourth duration are configured to detect reflections from objects (318) between the first distance and a second distance from the system.

Abstract: Disclosed are techniques for wireless sensing. In an aspect, a user equipment measures at least a line-of-sight path and a non-line-of-sight path of a first downlink positioning reference signal (DL-PRS) from a first transmission-reception point, measures at least an LOS path and an NLOS path of a second DL-PRS from a second TRP, measures at least an LOS path and an NLOS path of a third DL-PRS from a third TRP, and enables a location of a non-participating target object to be determined based, at least in part, on reference signal time difference (RSTD) measurements between a time of arrival of the LOS path of the first DL-PRS and the ToAs of the NLOS paths of the first, second, and third DL-PRS. In an aspect, the non-participating target object does not participate in determining its own location.

Abstract: Bi-static radio-based object location detection can include determining, by a wireless device, a location of a remote wireless device; obtaining a ToF and an angle of arrival (AoA) of a reflected WWAN reference signal reflected by a remote object; and determining a location of the remote object based on the location of the remote wireless device, the ToF, and the AoA. In another example, a wireless device includes a wireless transceiver; a non-transitory computer-readable medium; and a processor communicatively coupled to the wireless transceiver and non-transitory computer-readable medium, the processor configured to determine a location of a remote wireless device; obtain a ToF and an angle of arrival (AoA) of a reflected WWAN reference signal reflected by a remote object; and determine a location of the remote object based on the location of the remote wireless device, the ToF, and the AoA.

Abstract: Wireless communications systems may configure a subset of allocated resources (e.g., one or more resource elements (REs) of one or more allocated resource blocks (RBs)) as peak reduction tones (PRTs) for a peak-cancelation signal. For instance, wireless communications systems may configure a fixed PRT allocation based on a Costas array. In some examples, each column of a Costas array may correspond to a RB of a set of allocated resources. A transmitting device may thus identify one or more PRT REs based on the Costas array and a mapping of allocated RBs to the columns of the Costas array. For instance, a transmitting device may identify a pattern of PRT REs to use for a peak-cancellation signal based at least in part on a configured Costas array (e.g., where the peak-cancellation signal may reduce peaks of a corresponding data signal to ultimately reduce peak-to-average power ratio (PAPR) of a transmission).

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for detecting when a control link between a user equipment (UE) and a base station is lost and recovering the control link. In one example, a UE may detect that a control link with a base station is lost based on a timer or counter expiring or based on failing to receive signaling from the base station. In another example, a UE may be configured to transmit uplink transmissions to a base station to maintain a control link with the base station, and the base station may detect that a control link with the UE is lost if the base station fails to receive one or more uplink transmissions from the UE. If the control link is lost, the base station and the UE may communicate to re-establish the control link.

Abstract: Techniques are provide for neural network based positioning of a mobile device. An example method for determining a line of sight delay, an angle of arrival, or an angle of departure value, according to the disclosure includes receiving reference signal information, determining a channel frequency response or a channel impulse response based on the reference signal information, processing the channel frequency response or the channel impulse response with a neural network, and determining the line of sight delay, the angle of arrival, or the angle of departure value based on an output of the neural network.
