Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, achieving high communication speeds and low latency while managing battery consumption is challenging due to the increased computational load required for selecting optimal antenna modules and beams, especially at high frequencies where path-loss and service coverage are limited.
Innovation Solution
An electronic device with multiple antenna modules and a processor that identifies signal qualities across these modules, determines the optimal module for transmission/reception based on signal quality differences and channel information, and switches between them to maintain communication speed and low latency, considering the trade-off between computing load and performance.

Engineering Contradiction Analysis
1Speed
If computational amount for selecting optimal antenna module and beam is increased, then communication speed is maximized, but battery consumption increases
Solution Approach 1:
The patent changes the selection parameters from comprehensive channel quality indicators to simplified signal quality metrics (RSRP, RSRQ) and rank conditions. This parameter simplification allows faster antenna module selection while maintaining communication performance, thereby reducing computational load and battery consumption.
Solution Approach 2:
The patent segments the antenna module selection process into distinct decision stages: first checking signal quality difference threshold, then verifying rank condition, and finally selecting the antenna module. This segmented approach reduces computational complexity compared to evaluating all possible antenna modules comprehensively, thus lowering power consumption while maintaining communication speed.
2Loss of time
If computational amount for selecting optimal antenna module and beam is increased, then low latency is achieved, but battery consumption increases
Solution Approach 1:
The patent performs preliminary checks of signal quality difference and rank conditions before proceeding to antenna module selection. This preliminary action filters out unnecessary computational operations, achieving low latency by quickly determining the optimal antenna module without exhaustive search, thereby reducing battery consumption.
Solution Approach 2:
The patent simplifies selection parameters to signal quality metrics and rank conditions, enabling faster decision-making with reduced computational load. This parameter simplification achieves low latency while minimizing battery consumption by avoiding complex channel quality evaluations.
3Area of stationary object
If multiple antenna modules are used to cover different physical regions, then service coverage is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by selecting different antenna modules based on their specific coverage areas and signal characteristics. Each antenna module serves its optimal local region, and the selection algorithm chooses the most appropriate module for the current communication scenario, achieving comprehensive coverage while managing device complexity through intelligent selection.
Solution Approach 2:
The patent segments the coverage area into different regions served by different antenna modules. The selection algorithm divides the decision process into manageable steps (signal quality check, rank verification, module selection), reducing the perceived complexity while enabling multiple antenna modules to work together for extended service coverage.

AI summary
A method is performed by an electronic device that includes antenna modules AM1 and AM2. The method includes: while transmitting or receiving through AM1, receiving a specified wireless signal through AM1 and AM2; identifying a first signal quality for the specified wireless signal of AM1 and a second signal quality for the specified wireless signal of AM2; and in response to determining that a difference between the first signal quality and the second signal quality is within a specified signal quality range and that a rank of a wireless channel through which the specified wireless signal is received is two or more, selecting an antenna module to transmit or receive a wireless signal, from among AM1 and AM2, based on first channel information about AM1 and second channel information about AM2. The method includes transmitting or receiving the wireless signal using the selected antenna module.
