Then multiple two-dimensional images acquired at different rotation angles are reconstructed as four-dimensional images.

Abstract: A four-dimensional ultrasound imaging system including an ultrasound system, a two-dimensional capacitive ultrasound transducer, and an ASIC (Application Specific Integrated Circuit) chip is introduced. Specifically, a transmission driving circuit and a receiving circuit are integrated in the ASIC for driving the transducer to transmit ultrasound beams and receive reflected echoes. The ASIC is configured to perform microchip pre-beamforming on the received signals to reduce channel number, and then the processed signals are transmitted to the ultrasound system for analog to digital conversion, beamforming and coordinate conversion. A four-dimensional ultrasound image is obtained by fast and repeatedly acquiring three-dimensional images. In the present application, the ASIC chip is integrated in the transducer, so that the two-dimensional transducer can have fewer wires.

Abstract: This disclosure relates to methods, devices, and systems for wireless communications, and more particularly uplink reference signal repetition for non-terrestrial networks. A user terminal in a non-terrestrial network may identify an uplink reference signal format that includes a comb-based pattern of subcarriers within a first orthogonal frequency-division multiplexing (OFDM) symbol and within a second OFDM symbol for transmission of an uplink reference signal. The user terminal may map the uplink reference signal to a first set of subcarriers within the first OFDM symbol and to a second set of subcarriers within the second OFDM symbol in accordance with the comb-based pattern. Thereby, the user terminal may transmit, to a base station in the non-terrestrial network, the uplink reference signal on the mapped subcarriers of the OFDM symbols, which may be transmitted coherently.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device such as a user equipment (UE) may receive control signaling from a scheduling device such as a base station which indicates a configuration for decoding control channel information at the UE using a single discrete transform process. In such cases, the configuration may be for decoding control channel information such as downlink control information (DCI) that is time multiplexed with data channel information in one or more symbols of a single carrier waveform. Using the configuration, the UE may decode the control channel information and the data channel information using the discrete transform process.

Abstract: A scheduling offset between an uplink and downlink radio frame timing structure of a user equipment (UE) may be updated to provide for more efficient utilization of hybrid automatic repeat request (HARQ) processes in a non-terrestrial network. For instance, different UEs may experience different round trip delays (RTDs) with a non-terrestrial cell. Different UEs may be configured with different scheduling offsets such that scheduling delays may be reduced and HARQ processes identifiers may be reused more rapidly. Additionally or alternatively, wireless communications systems may define one or more separation distances (or timing thresholds) for timing between communications and HARQ processes may be reused based on the separation distance threshold (e.g., such that a satellite may reuse a HARQ process ID for two scheduled communications that have not yet been performed by the UE).

Abstract: Non-terrestrial networks (NTNs) may establish uplink (UL) and downlink (DL) radio frame timing structures to efficiently account for propagation delay and propagation delay variation associated with communications in the NTN. NTNs may manage (synchronize) radio frame timing structures of base stations (e.g., satellites) and user equipment (UEs) in the NTN. Further, UEs may determine timing advance (TA) values to be applied to UL transmissions based on their respective scheduling offset (e.g., offset in UL and DL radio frame timing structures), as well as based on propagation delay or round trip time (RTT). As such, served UEs may determine UL timing such that UL transmissions from the UEs to a satellite arrives at the satellite in a time synchronized manner. In other cases, a satellite may determine UL timing, based on reception timing, such that various UEs in the NTN may implement uniform UL and DL radio frame timing structures.

Abstract: Techniques are described for supporting user equipment (UE) positioning in a non-terrestrial network (NTN). To allow calculating a position/location of a UE based on reference signal (RS) measurements to and from one satellite (or a terrestrial base station), a device may be configured to calculate a doppler measurement and a range measurement and report such measurements to be used by a location server to calculate a UE position. An example device may receive a first RS (with the first RS being one of a positioning reference signal (PRS) or a sounding reference signal (SRS)), receive a second RS associated with the first RS, calculate a doppler measurement based on one or both of the first RS or the second RS, and report the doppler measurement. The doppler measurement (such as a measured frequency offset) may be used by a location server to calculate a UE position on the earth surface.
