Autonomous Beamforming Rules for Multi-Mode Wireless Communication

Solution Overview

Problem

Existing wireless communication systems, particularly in NR and LTE, face inefficiencies in beamforming configurations due to the need for explicit network signaling for beam changes, leading to increased latency and communication overhead.

Innovation Solution

Wireless nodes, such as UEs and IAB-nodes, autonomously determine beamforming configurations based on communication modes and preconfigured rules, allowing for efficient adjustments without explicit network signaling.

1Reliability

If explicit network signaling is used for beamforming configuration changes, then beamforming adjustments can be made, but communication latency and overhead increase

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The wireless node autonomously determines beamforming configurations by monitoring communication modes (full-duplex, half-duplex, TDD) and applying preconfigured rules, eliminating the need for explicit network signaling for each beam change. This self-service mechanism reduces latency while maintaining reliable beamforming adjustments through locally stored configuration rules

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Beamforming configuration rules are preconfigured and stored in the wireless node before operation. When communication modes change, the node can immediately apply the corresponding pre-determined beamforming configuration without waiting for network signaling, thus reducing communication latency while ensuring configuration accuracy
