Decentralized Power Allocation Signaling in Wireless Networks

The patent segments the gradient computation into local components. Each node computes only its local gradient component based on locally available information (received signal power and local channel state), rather than requiring global information distribution. This segmentation allows distributed implementation while reducing energy consumption and computational complexity at each node.

The system enables self-service by allowing each node to autonomously compute its gradient component using only local measurements and pre-distorted signaling information. Nodes independently determine their own power adjustments without requiring centralized control or extensive information exchange, thus reducing overall network energy consumption while achieving optimal power allocation.

The patent applies preliminary action by pre-distorting the transmitted signals at each node before transmission. This pre-distortion incorporates channel state information and interference characteristics in advance, allowing receiving nodes to extract accurate gradient components without requiring extensive subsequent information exchange. The gradient formation accuracy is maintained while signaling complexity is reduced because the necessary information is embedded in the pre-distorted signals.

The pre-distorted signaling acts as an intermediary that carries gradient-related information efficiently. Instead of nodes exchanging extensive raw data about channel states and received powers, the pre-distorted signals serve as a compact mediator that encodes the necessary gradient information, reducing signaling overhead while maintaining gradient formation accuracy.

The patent implements feedback mechanisms where each node measures the received signal power from others and uses this information to compute its gradient component. This feedback loop allows decentralized nodes to automatically coordinate their power levels based on actual network conditions, maintaining network autonomy while simplifying power coordination through localized feedback rather than complex centralized control.

The patent merges the functions of channel estimation, interference measurement, and gradient computation into a unified local process at each node. By combining these functions and using pre-distorted signaling to carry multiple pieces of information simultaneously, the system achieves efficient decentralized power coordination without requiring separate coordination protocols, thus improving ease of operation while maintaining autonomy.
