Solution Overview
Problem
In the context of 5G wireless communication systems operating in the mmWave band, existing technologies face challenges in efficiently selecting optimal beamforming techniques due to high attenuation and the need for precise antenna management, particularly in varying environmental conditions.
Innovation Solution
An electronic device with multiple panel antennas selects an optimal codebook based on environmental information such as temperature, power consumption, and channel state, and receives control information from a base station to perform beamforming, optimizing beam patterns and antenna usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If beamforming is used to increase transmission distance and reduce signal attenuation in mmWave band, then data transmission rate is improved, but device complexity increases due to multiple panel antennas and codebook selection requirements
Solution Approach 1:
The patent implements dynamic codebook selection based on environmental conditions. The electronic device determines at least one panel antenna based on environmental information (temperature, power consumption, channel state) and selects an optimal codebook from multiple available codebooks. This dynamic adaptation allows the system to optimize beamforming performance for different operating conditions, resolving the contradiction between maintaining high data transmission rates and managing device complexity.
Solution Approach 2:
The patent changes the parameter of codebook selection based on environmental parameters. By selecting different codebooks according to temperature, power consumption levels, and channel state information, the system adapts its beamforming characteristics to match current operating conditions. This parameter-based selection mechanism enables the system to achieve optimal performance without requiring complex real-time optimization algorithms.
2Length of stationary object
If multiple panel antennas are used to overcome path loss in mmWave band, then transmission distance is extended, but power consumption increases
Solution Approach 1:
The patent incorporates power consumption information as a key parameter for codebook selection. By evaluating the power consumption characteristics of different panel antennas and selecting codebooks that optimize performance while minimizing energy usage, the system extends transmission distance without proportionally increasing power consumption. The environmental information includes power consumption data that guides the selection process.
Solution Approach 2:
The patent applies local quality by determining at least one specific panel antenna based on environmental conditions rather than uniformly activating all panel antennas. This selective activation approach allows the system to extend transmission distance in specific directions or under specific conditions while consuming less power overall, as only the most appropriate panel antennas are activated based on the determined criteria.
3Reliability
If adaptive codebook selection based on environmental information is implemented, then beamforming performance is optimized, but measurement and detection difficulty increases
Solution Approach 1:
The patent performs preliminary determination of panel antennas based on environmental information before actual beamforming operations. By pre-selecting the appropriate panel antennas and codebooks based on temperature, power consumption, and channel state information, the system reduces the complexity of real-time measurements and detections during active communication. This preliminary action ensures that beamforming performance is optimized while minimizing the difficulty of ongoing measurements.
