Solution Overview

Problem

Existing communication systems require extensive traversal search of operation modes, which is time-consuming and computationally intensive, making it difficult to determine the optimal operation mode efficiently.

Innovation Solution

A method and apparatus for determining operation modes based on position and positioning error information of a target terminal, including beam direction, beamforming, and polarization modes of intelligent surfaces, relay devices, and IAB nodes, using signaling to adjust and control electromagnetic signals for quick determination of optimal operation modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traversal search of operation mode is performed to determine optimal operation mode, then communication system performance is improved, but time consumption and calculation amount increase significantly

Engineering Contradiction:

Improvecommunication system performanceVSAvoidtime consumption

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-establishing a mapping relationship between position information and operation modes. The network side device determines position information of the terminal and directly queries the corresponding operation mode from the pre-established mapping, eliminating the need for real-time traversal search of all possible operation modes. This significantly reduces time consumption while maintaining optimal communication performance.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by creating a simplified representation (mapping relationship) of the complex operation mode space. Instead of exhaustively searching all possible operation modes, the system copies the essential information (position data) and uses it to directly determine the optimal operation mode through the pre-built mapping, reducing computational complexity and time requirements.
