Abstract: This disclosure is directed to systems and methods for interference mitigation in satellite communication. For satellite communication, an electronic device may perform a GNSS position fix prior to establishing satellite communication. In some cases, a GNSS downlink frequency band may be close to a satellite uplink frequency band, and as a result a first device communicatively connecting to a satellite downlink frequency band may interfere with one or more other devices in close proximity attempting to connect to the GNSS uplink frequency band, and consequently the first device may prevent the one or more other devices from performing the GNSS position fix. Because of this, one electronic device may block satellite communication for multiple other electronic devices. This may be particularly relevant in situations involving large crowds (e.g., festivals, sporting events), during calamity events, and/or in outdoor scenarios (e.g., group hikes).

Abstract: Embodiments disclosed herein relate to enabling direct wireless device-to-device communication between sleepy end devices (SEDs) of a mesh (e.g., Thread®) network. A router may forward packets between end devices of the mesh network. However, if the router is not available, SEDs may not be able to communicate with each other using a mesh protocol. Embodiments presented herein enable end devices of the mesh network to communicate directly, without a router. Some embodiments are directed to changing a role of an end device to temporarily act as a router for a particular target end device. The role change may be based on a trigger event and may be temporary until a target action is performed by the target end device. In some embodiments, the end devices continue to operate as SEDs and use coordinated sampled listening techniques to communicate via the mesh protocol.

Abstract: User equipment includes one or more antennas, a receiver coupled to the one or more antennas, and processing circuitry coupled to the receiver and configured to cause the user equipment to receive downlink signals at each communication cycle using a predetermined beam in a beam time slot. Based on processed downlink signals and other relevant information the user equipment may determine a desired beam for the next communication cycle. If the desired beam is the same as the predetermined beam, the user equipment may continue using the predetermined beam at the next communication cycle. If the desired beam is different from the predetermined beam, the user equipment may switch to the desired beam at the next communication cycle. In this way, the user equipment may continue tracking a desired beam to maintain reliable data communications with a communication node.

Abstract: A communications system may include user equipment (UE) device, satellites, and a gateway. The UE and gateway may perform implicit handover in which the UE and gateway independently identify the same serving satellite using ephemeris data, without additional signaling overhead. The UE may also characterize its channel conditions. When insufficient, the UE may transmit an explicit handover message to the gateway via a different satellite visible to the UE. The explicit handover message may include a satellite identifier and a lock bit. The gateway may use the satellite identifier to convey wireless data with the UE via the different satellite during the next cycle. The gateway may use the lock bit to know how to perform handover away from the different cycle during subsequent cycles. In this way, the UE may direct handover, given that the gateway has no knowledge of the channel condition at the UE.

Abstract: Systems and methods for coordinating data sampling among devices include a set of electronic devices that may periodically sample energy data from a smart meter according to sample timing information. The sample timing information may specify a set of times to sample energy data for each electronic device. The set of electronic devices may take turns in sampling energy data from the smart meter so that individual electronic devices may reduce power consumption by sampling less frequently. A server may determine the sample times for the electronic devices and may instruct the electronic devices to sample energy data. Additionally, each individual electronic device may leave and/or join wireless communication networks less frequently than if each individual electronic device performed every sample. Accordingly, the coordinated sampling may decrease the radio resource usage and/or bandwidth usage of any individual electronic device.

Abstract: Embodiments for performing a fast return to Wi-Fi following completion of a cellular voice call are provided. These embodiments include detecting that a device has switched from communicating over a Wi-Fi interface to communicating over a cellular interface; determining the earliest time that the device can switch back to Wi-Fi; and instituting the switch. In some embodiments, the process of performing a fast return to Wi-Fi is carried out by devices having small form factors, such as smartwatches and other wearables, which may be susceptible to coexistence and peak power problems. The fast return to Wi-Fi embodiments disclosed herein allow a device to perform a voice call over a cellular interface when Wi-Fi calling is not available, and switch over to a Wi-Fi interface immediately upon completion of the voice call in order to conserve battery life, achieve higher data speeds, and avoid high costs associated with cellular data transmissions.

Abstract: This disclosure relates to techniques for efficient sparse network resource usage and connection release procedures. According to some embodiments, a wireless device may utilize techniques for efficiently releasing a radio resource control (RRC) connection, including techniques that avoid or reduce the occurrence of random access procedures when out-of-sync with the network when the RRC connection is being released. In some embodiments, a wireless device may utilize techniques for efficiently sparsely using network uplink resources, including techniques that avoid or reduce the occurrence of random access procedures to regain timing alignment to perform uplink communication when out-of-sync with the network.
