Engineering Contradiction Analysis
1Quantity of substance
If 4G LTE cellular system is used for video transmission, then existing infrastructure can be maintained, but bandwidth is insufficient for 8K video streaming
Solution Approach 1:
The patent transitions from 4G LTE to 5G NR cellular systems, changing the fundamental transmission parameters including bandwidth capacity, modulation schemes, and spectral efficiency to enable 8K video streaming. This parameter change allows the system to handle the high bitrate requirements of 8K video while maintaining cellular infrastructure advantages.
2Measurement precision
If beam related information is used to determine UE position, then positioning accuracy is improved, but system complexity increases
Solution Approach 1:
The system utilizes uplink beamformed signals that are already being transmitted for communication purposes to simultaneously determine UE position. The base station processes the beam related information (beam ID, beam direction) that the UE naturally transmits during normal beam management procedures, enabling positioning without requiring separate dedicated signaling or additional UE functionality.
Solution Approach 2:
The beam management mechanism serves dual purposes: maintaining optimal communication links through beamforming and determining UE position for video capture. The same beam related information exchanged for wireless communication optimization is simultaneously used for positioning, eliminating the need for separate positioning infrastructure.
3Productivity
If video capturing devices are integrated on base station, then real-time video monitoring is enabled, but device complexity and cost increase
Solution Approach 1:
The patent integrates video capturing devices directly on the base station platform, combining communication infrastructure and video monitoring functions into a single unified system. This merging allows the base station to simultaneously perform wireless communication and real-time video capture, eliminating the need for separate video surveillance infrastructure.
Solution Approach 2:
The base station determines UE position using beam related information before initiating video capture. This preliminary positioning action allows the system to pre-select appropriate video capturing devices based on UE location, ensuring that video monitoring is activated only when and where needed, thus optimizing resource utilization.
