    Abstract: Implementations relate to identifying, by a relay device, a first message received from a first requesting device of a plurality of requesting devices; identifying, by the relay device, a second message received from a second requesting device of the plurality of requesting devices; determining, by the relay device based at least in part on a parameter of the first message, that the first message has a first priority level that satisfies a priority threshold; determining, by the relay device based at least in part on a parameter of the second message, that the second message has a second priority level that does not satisfy the priority threshold; transmitting a relay message to a remote device based at least in part on the first message; and transmitting a backoff message to the second requesting device.

    Abstract: A communications network may include user equipment (UE) devices. When a first UE device becomes off-grid and has an emergency message, the first UE device may transmit device-to-device signals for receipt by a second UE device. The signals may include one or more preambles that precede the emergency message and that are used by the second UE device to perform synchronization with the first UE device. The second UE device may periodically activate a receiver during a series of windows to listen for the signals, may receive a preamble sequence during one of the windows, and may synchronize its timing to the first UE device for receipt of the emergency message based on the preamble sequence. This may allow the UE devices to be synchronized for transfer of the emergency message over long distances while consuming a minimal amount of power on the second UE device.

    Abstract: A communications network may include a relay device that receives device-to-device (D2D) signals. In an ad hoc mode, the relay may consume relatively little power while receiving relatively few messages from relatively few transmitting devices in the D2D signals. In an organized mode, the device may consume relatively high power while receiving many messages from many transmitting devices in the D2D signals. A receiver on the device may transition from the ad hoc mode to the organized mode in response to a first criterion and may transition from the organized mode to the ad hoc mode in response to a second switching criterion. This may allow the device to balance communications load and power consumption while relaying messages such as emergency messages received over D2D signals given that the signals may arrive rarely or in clusters due to an unforeseen event.
