    Abstract: An electronic device may include a display with an optical combiner. The combiner may include a waveguide and a cross coupler on the waveguide. The combiner may redirect light from a display module to an eye box while passing world light to the eye box within a field of view. The cross coupler may include surface relief gratings or other broadband gratings. The combiner may include an angular filter that at least partially overlaps the cross coupler. The cross coupler may include surface relief grating structures or other broadband gratings. The angular filter may include angled absorbers or diffractive gratings. The angular filter may prevent world light that would otherwise produce distracting flares at the eye box (e.g., world light incident on the waveguide outside the field of view such as high-incident angle light from an overhead light source) from passing to the cross coupler.

    Abstract: This disclosure is directed to shared antenna tuning. An electronic device may receive a global navigation satellite system (GNSS) tune request to tune a shared antenna to a GNSS signal frequency. The electronic device may then tune the antenna to the GNSS signal frequency and enable a GNSS receiver. The electronic device may also receive a cellular tune request to tune the antenna to a cellular frequency. The electronic device may tune the antenna to a cellular frequency and may deactivate the GNSS receiver or blank the GNSS receiver. In some embodiments, the electronic device may also communicate with a Low Earth Orbit (LEO) satellite. During LEO satellite communication, the electronic device may transmit a signal to blank a GNSS L1 receiver to avoid signal interference with the LEO satellite communication, and activate a GNSS L5 receiver to receive GNSS signals.

    Abstract: Systems and methods for clustering in cell-free networks are described herein. A cluster of one or more base stations provides radio access network (RAN) functionality to a user equipment (UE) within the wireless communication system in a cell-free manner (e.g., without using a base-station-centric cell context, as in prior wireless communication systems). A cluster that is serving a UE comprises one or more connected base stations (cBSs) that actively serve the UE. A clustering control function (CCF) of the network establishes and maintains the cluster that is serving one or more UEs. Herein, messaging systems and messaging types used by the CCF, base station(s), and UE(s) within this cell-free context are discussed. Initial clustering methods used by a CCF to form a cluster for a UE are discussed. Further, clustering update methods used by a CCF to maintain/modify a cluster for a UE are discussed.

    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for managing dormant cell(s) within a set of cells for multi-cell scheduling. For example, a UE can be configured to receive information associated with a set of cells for multi-cell scheduling and determine a first reference cell based on the received information. The UE is further configured to determine a second reference cell for performing one or more of blind decode counting and control channel element counting in response to determining that the first reference cell is in a dormant mode. The UE is further configured to perform the one or more of blind decode counting and control channel element counting using the second reference cell.

    Abstract: In accordance with aspects of the present disclosure, a user equipment (UE) may receive a configuration for mapping PC5 quality of service (QoS) flows to frequencies. The UE may also receive a sidelink logical channel configuration message indicating that sidelink data associated with a logical channel can be mapped to one or more sidelink carriers on a list of allowed sidelink carriers. Accordingly, the UE may transmit the sidelink data associated with the logical channel via at least one sidelink carrier on the list of allowed sidelink carriers based at least in part on mapping the logical channel to the at least one sidelink carrier in accordance with the configuration for mapping and the sidelink logical channel configuration message.

    Abstract: A mobile device can include ranging circuitry to determine distance to another mobile device. A first wireless protocol can establish an initial communication session to perform authentication and/or exchange ranging settings. A second protocol can perform ranging, and other wireless protocols can transmit content. In one example, the distance information can be used to display a relative position of another device on a user interface of a sending device. The user interface can allow a user to quickly and accurately select the recipient device for sending the data item. As another example, the distance information obtained from ranging can be used to trigger a notification (e.g., a reminder) to be output from a first mobile device or used to display a visual indicator on a receiving device. Proximity of a device (e.g., as determined by a distance) can be used to suggest recipient for a new communication.
