A low complexity user equipment (UE) can communicate with another UE (e.g., with a high-end UE or a more capable UE) via a device-to-device communication link (e.g., via a sidelink), and the low complexity UE can utilize the device-to-device link to improve (e.g., simplify, speed up, etc.) a random access procedure performed by the low complexity UE. For example, the low complexity UE can request a contention-free random access (CFRA) resource via the device-to-device link with another UE. Another device (e.g., another UE in device-to-device communication with the low complexity UE) can receive the request from the low complexity UE and forward the request to the network (e.g., to a base station). The network can then configure the CFRA resource for the low complexity UE. Upon receiving the CFRA configuration, the low complexity UE can perform a random access procedure (e.g., a CFRA procedure) with the network (e.g., with the base station) accordingly.

The invention relates to power efficient synchronization for long distance device-to-device communication. A communication network is provided that may include a user equipment (UE) device.

The second UE device may periodically activate a receiver to listen for the signal during a series of windows, may receive a preamble sequence during one of the windows, and may synchronize timing of the second UE device to the first UE device to receive the emergency message based on the preamble sequence. This may allow the UE devices to be synchronized to transmit emergency messages over long distances while consuming a minimum amount of power on the second UE device.

A Petri net-based task scheduling method for heterogeneous environments relates to the field of collaborative decision-making and resource optimization in edge computing systems. During scheduling, the input tasks and their dependencies are first modeled as directed acyclic graphs (DAGs), and then converted into Petri nets to uniformly represent task states, resource constraints, and device collaboration relationships, in conjunction with device status information. Subsequently, graph attention networks are used to extract PN topological features, and a dynamic transition triggering strategy is learned using a dual-deep Q-network. The task unloading and resource allocation sequences are optimized through a reward function, and the sequence validity is further verified by a sequence detection module. During task execution, tasks are scheduled in real-time according to a reinforcement learning strategy, and the network state and decision model are dynamically updated based on environmental feedback, forming a closed-loop optimization. This invention significantly improves task throughput and resource utilization in heterogeneous edge environments, and is particularly suitable for device-to-device collaborative scenarios with complex task dependencies and dynamically changing resources.
