Abstract: Sidelink pathloss between a remote user equipment device (UE) and a relay UE may be determined based at least on transmit power information provided by the relay UE to the remote UE. The remote UE may receive, via a sidelink discovery signal from the relay UE, a message that includes first information representative of a transmit power of the relay UE and/or second information representative of a measured receive signal power of a sidelink solicitation signal previously transmitted by the remote UE and received by the relay UE. The remote UE may determine a sidelink pathloss between the remote UE and the relay UE based at least on the first information and/or the second information. The remote UE may select/reselect a relay UE based on corresponding pathlosses determined for the respective paths between the remote UE and different respective relay UEs.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for a wireless communication system in an unlicensed spectrum. A user equipment (UE) device of the wireless communication system includes a processor circuitry and radio front end circuitry. The processor circuitry is configured to acquire a channel occupancy time (COT) in the unlicensed spectrum, and determine a number of remaining consecutive subframes allocated for physical uplink shared channel (PUSCH) transmission to a base station. The processor circuitry is configured to generate uplink control information (UCI) to indicate a COT sharing boundary occurring at an end of the remaining consecutive subframes. The radio front end circuitry is coupled to the processor circuitry and configured to transmit the UCI in the PUSCH) transmission during one of the remaining consecutive subframes. The processor circuitry is also configured to monitor downlink transmissions from the base station following the COT sharing boundary.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for network assisted side-link resource configuration for unicast and/or multi-cast/groupcast communications in V2X networks. A UE may, after establishing an RRC connection with a base station, transmit, to the base station, V2X connection information. The V2X connection information may include a V2X identifier associated with the UE and a V2X identifier associated with a target UE. The UE may receive, from the base station, a side-link configuration for data transmission with the target UE. The side-link configuration may include a resource allocation defined in time and frequency (e.g., a transmit/receive pool). The UE may communicate with the target UE using the resource allocation included in the side-link configuration.

Abstract: A user equipment (UE) is configured to store information related to network slices. The UE receives network slice related information associated with a first public land mobile network (PLMN), stores the network slice related information in a database locally at the UE, identifies a predetermined condition and removes at least a portion of the network slice information associated with the first PLMN based on camping on a second PLMN and the predetermined condition.

Abstract: Apparatuses, systems, and methods for beam failure recovery based on a unified TCI framework. A UE may receive, from a base station, a configuration for a BFR procedure for a CCG. The CCG may include at least two CCs and the UE may periodically receive, from the base station, at least a first BFD RS and a first CBD RS in a first CC included in the CCG. The UE may detect, based on the first BFD RS, a beam failure in at least the first CC and send, to the base station, a BFRQ. The BFRQ may include a candidate beam selected based on at least the first CBD RS and may be sent via a PRACH or MAC CE. The UE may receive, from the base station, a BFR response and apply the candidate beam to the first CC and at least one additional CC of the CCG.

Abstract: An ultrasonic proximity sensor can determine one or more characteristics of a local environment. For example, the sensor can emit an ultrasonic signal into a local environment and can receive an ultrasonic signal from the local environment. From a measure of correlation between the emitted and the received signals, the sensor can classify the local environment. By way of example, such a sensor can assess whether an in-ear earphone is positioned in a user's ear. A media device in communication with the sensor can transmit an audio signal to the earphone for audio playback responsive to a determination by the sensor that the earphone is in the user's ear and can redirect the audio signal to another playback device responsive to a determination by the sensor that the earphone is not in the user's ear. Related and other aspects also are described.

Abstract: Embodiments relate to identifying locations in an image where a green ghost is likely to occur by processing a raw version of the image. A block of pixels in the raw image is extracted and then each pixel value in the block is compared with a threshold value of a corresponding color channel. The compared results are then processed to generate bright light information for the block, indicating whether the green ghost is likely to be present at a location of the image diagonally opposed to the location of the block in the image relative to an optical center of an image sensor. By processing the raw image without subsequent processing prone to introducing artifacts and creating false positive, a likely location of the green orb or green ghost may be more accurately identified.

Abstract: A method and apparatus of a device that uses a video jitter buffer to buffer the video frames for a received video stream is described. The device uses the video jitter buffer to estimate the delay variability of the frames and pick a target delay that will help harmonize the playback with minimal loss and delay. This is achieved by estimating the delay spread, which is the result of performing statistical analysis of the measured lags of the video frames received. The video jitter buffer provides target delay recommendation and reference frame information to the video player in order to anchor the playback and schedule the frames presentation time.

Abstract: Apparatuses, systems, and methods for SRS collision handling. A wireless device may determine whether simultaneous transmission of at least two sounding reference signals (SRSs) is allowed; if it is determined that the simultaneous transmission of the at least two SRSs is allowed, transmit the at least two SRSs simultaneously; and if it is determined that the simultaneous transmission of the at least two SRSs is not allowed, transmit one SRS of the at least two SRSs, and drop the other SRS of the at least two SRSs.
