Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB), Evolved Node-B (eNB) and methods of communication are generally described herein. The UE may detect one or more LTE synchronization signals from an eNB over an LTE Uu interface between the UE and the eNB. The LTE synchronization signals may be detected in resources allocated for LTE communication. The LTE synchronization signals may be detected in accordance with an LTE protocol. The UE may determine, based on the LTE synchronization signals, a reference timing and a reference frequency for NR vehicle-to-everything (V2X) communication over an NR PC5 interface with another UE.

Abstract: Aspects of the subject technology relate to a shaker module for an electronic device. The shaker module may include a movable component that is resiliently suspended in relation to a voice coil by one or more gap-separated pairs of the flat springs. The flat springs reduce the z-height of the shaker module for implementation in, for example, compact electronic devices. The gap-separated pairs of flat springs facilitate adjustment of the resonance frequency of the shaker module substantially independently of adjustments to drop performance, while providing stability against unwanted rocking motions of the movable component.

Abstract: An electronic watch includes a housing, a display positioned at least partially within the housing, a cover covering at least part of the display, and a crown having a portion positioned along a side of the housing. The crown may include an inner member that is rotationally constrained relative to the housing and an outer member that is rotationally free relative to the inner member. The device may further include a rotation sensor configured to sense a rotation of the outer member relative to the inner member.

Abstract: Some embodiments include an apparatus, method, and computer program product for tracking reference signal (TRS) support of high speed use cases of 5G communications in a single frequency network (SFN), where a user equipment (UE) can measure a Doppler offset of a combined signal from two or more transmission reception points (TRPs) of the 5G communications system. A 5G node B (gNB) node can transmit a periodic, semi-persistent (SP), or aperiodic TRS with high measurement density that the UE uses to measure a Doppler offset of a combined signal. For example, the gNB can: trigger the aperiodic TRS based on a downlink assignment; and/or use lower layer signaling to arrange to transmit a semi-persistent TRS or a periodic TRS with a reduced periodicity. In some embodiments, the gNB can measure the Doppler offset based on an uplink signal, and transmit a TRS based on a pre-compensated Doppler frequency.

Abstract: An optical module includes a beam-tilting light source enclosure. The enclosure is coupled to a substrate that includes a light emitter connected thereto. The enclosure has a geometry such that the enclosure has a first surface configured to couple substantially flat to the substrate and a second surface tilted with respect to the first surface and configured to couple substantially flat to a component of an electronic device through which the light is to project. The enclosure is optically transmissive and covers the light source when coupled to the substrate. In this way, the enclosure may be assembled and used in the electronic device by coupling the first surface to the substrate and coupling the second surface to the component.

Each retroreflective surface feature of the array of retroreflective surface features may be formed as a corner-cube with three perpendicular faces. The SMI sensor or associated processing electronics may compare originally emitted light with reflected light to identify a movement or distance of the rotatable crown with respect to the SMI sensor.

Abstract: Systems and methods are disclosed herein for using integrated access and backhaul (IAB) nodes configured to provide multi-access edge computing (MEC) functionality. An IAB node may include a MEC functionality that includes an instance of an application configured for MEC. A UE using the application connects to the network through an access link with the IAB node and establishes a PDU session for traffic of the application with a core network (CN). The CN may determine that the traffic corresponds to the application, and that an instance of the application is present on the IAB node. Accordingly, the CN may instruct the IAB donor to instantiate a remote packet data convergence protocol (PDCP) layer and, in some cases, a remote service data application (SDAP) layer that are configured to route the traffic from the UE for the application to the instance of the application on the IAB node.

Abstract: Systems, methods and devices can are provided, which can include configuring one or more bandwidth parts for a secondary cell (SCell) that is in communication with a user equipment (UE). A base station transmits to a UE a first radio resource control (RRC) message including one or more configuration parameters for a first bandwidth part (BWP) associated with a secondary cell (SCell). The UE communicates a first message with the SCell via the first SCell BWP. The UE receives a second RRC message indicating a change from the first SCell BWP to a second SCell BWP to be used for SCell communications. The UE communicates a second message with the SCell via the second SCell BWP.

Abstract: A 3GPP LTE protocol enhancement realizes the full benefit of discontinuous reception (DRX) in Long Term Evolution networks by coordinating and aligning DRX operations for conserving power and timing overhead. A dual connectivity enabled User Equipment (UE) comprising a processor and transceiver is configured to align DRX configuration between counterpart Evolved Node Bs (eNB)s, wherein counterpart eNBs are a Master eNB (MeNB) and a Secondary eNB (SeNB) simultaneously connected to the UE, communicate system frame timing and system frame number (SFN) information between the counterpart eNBs, align DRX start offset (drxStartOffset) values for the counterpart eNBs according to the communicated system frame timing and SFN information to compensate for offsets in system frame timing, and allow the start of a DRX ON duration at specific frame or sub-frame times determined by the drxStartOffset values, after the expiration of a DRX inactivity timer.

Abstract: A display having a reflective display panel may provide image light to an eye box. The panel may include mirrors rotatable between first and second angles. The mirrors may take a non-zero time period to transition between the first and second angles. During the non-zero time period, the light source may emit pulses of illumination. The mirrors may reflect the pulses of illumination as offset pupils of image light. The mirrors may be at respective intermediate angles while reflecting each of the pulses of illumination. The mirrors may toggle between the first and second angles at a sufficiently fast rate such that the offset pupils form an effective pupil that is expanded in at least one dimension. If desired, the offset pupils may be used to display virtual objects in different focal planes at the eye box.

The one or more processors further transmit, using the transceiver, the CTS frame based on the determined format on at least one sub-channel on which the RTS frame was received and that the at least one sub-channel is idle.

Abstract: To reduce the beam reporting latency, a base station may include a sounding reference signal (SRS) indication to a wireless communication device (UE) as part of the transmission configuration information (TCI) transmitted to the UE, allowing the UE to receive a corresponding downlink signal using the same beam (or with the same beam) the UE used to transmit (or with which the UE transmitted) the SRS indicated in the TCI. The SRS may be one of multiple SRSs previously transmitted by the UE. The UE may transmit the multiple SRSs periodically and/or according to semi-persistent scheduling, or it may transmit them aperiodically. Therefore, the UE does not need to report the beam quality, and the base station may perform the necessary beam measurement(s) instead. Various parameters and conditions may be defined for the UE to support SRS-based TCI.

The MAC CE may include at least four bits indicating the number of slots. The DCI may include at least one field indicating the number of slots.

Alternatively, the timer may be used by the UE and the UE may request the new GUTI upon expiry of the timer, e.g., using an existing message or a new message, as desired.
