Abstract: Some aspects of this disclosure include apparatuses and methods for implementing transmission power control. Some aspects relate to an electronic device including a transceiver configured to communicate with a second electronic device and a processor communicatively coupled to the transceiver. The processor is configured to receive an identification information of the second electronic device and receive, from the second electronic device, at least one of a plurality of feedback signals. The plurality of feedback signals includes a first feedback signal generated based on a link quality query from the electronic device and a second feedback signal including an encoded channel status information embedded within an acknowledgment (ACK) frame from the second electronic device. Based on the received identification information and the at least one of the plurality of feedback signals, the processor is configured to adjust transmission power of a signal to be transmitted to the second electronic device.

Abstract: The present disclosure relates to techniques for localizing devices connected to wireless networks, such as wireless mesh networks. In particular, a device connected to a wireless mesh network may maintain and share information, such as location data and identifiers, regarding the device and other devices connected to the device. The device itself or a computing system to which the device connects may determine locations for the devices in the wireless mesh network and generate a device map that indicates the locations of the devices.

Abstract: The present disclosure relates to several techniques for reducing the occurrence of data collisions, which can occur when multiple devices simultaneously transmit data in the same (frequency) channel. For example, a turnaround time in which a device switches from a receive mode of operation to a transmit mode of operation may be reduced based on the device and another device indicating that they are capable of operating with a reduced turnaround. As another example, devices may use learning-based turnaround estimation to determine a turnaround time supported by other devices and utilize the determined turnaround time, for instance, instead of a longer turnaround time. As yet another example, multiple clear channel assessments may be performed before transmitting data. For instance, a first clear channel assessment may be performed during a backoff period, and a second clear channel assessment may be performed afterwards before data is transmitted.

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: A method is provided. The method includes attaching a user device to a wireless network via a router of a first communications protocol. The method includes determining, based on information about a second session using a second communications protocol, a first time window and a second time window. The method includes determining to perform a first session using the first communications protocol in the first time window. The method includes performing a first arbitration between the first session and the second session. The method includes determining, based on the first arbitration, that the first session has a priority over the second session in the second time window. The method includes performing a second arbitration between the first session and a third session using a third communications protocol. The method includes determining, based on the second arbitration, whether to perform the first session in the second time window.

Abstract: The present disclosure relates to techniques for wireless communication between electronic devices in a wireless network, such as a mesh wireless network. For example, a first electronic device may include processing circuitry that is configured to cause a transceiver of the first electronic device to transmit to a second electronic device in a wireless network an indication of time slots. The processing circuitry may cause at least a portion of the transceiver to enter a low power state during one or more times outside the time slots and cause the transceiver to exit the low power state to transmit or receive wireless signals during the time slots.

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.
