Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently establishing beam associations between network nodes and user equipment (UEs) due to the lack of effective methods for identifying optical identifiers, which hinders optimal beamforming and communication efficiency.
Innovation Solution
The implementation of optical beacons with a repeated modulation pattern to indicate optical cell identifiers or radio network temporary identifiers (RNTIs) allows UEs and network nodes to establish beam associations based on these identifiers, facilitating improved communication and beamforming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If optical beacons with repeated modulation patterns are transmitted to indicate optical identifiers, then beam association establishment is improved, but system complexity increases
Solution Approach 1:
The patent applies periodic action by transmitting optical beacons with repeated modulation patterns at regular intervals. The optical identifiers are encoded in periodic optical signals that can be detected and decoded by UEs, enabling reliable beam association establishment through the repetitive nature of the signals, which improves detection reliability while maintaining manageable system complexity through standardized periodic transmission.
2Productivity
If optical beacons are used to indicate optical cell identifiers and RNTIs, then communication efficiency is improved, but detection and measurement difficulty increases
Solution Approach 1:
The patent employs color changes by utilizing different optical wavelengths or colors to encode various identifiers. Optical beacons transmit cell identifiers, RNTIs, and other information through distinct optical color patterns that can be differentiated by UEs, improving communication efficiency while simplifying detection through the natural spectral separation of different colors rather than requiring complex signal processing.
