Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional wireless communication systems face challenges in achieving enhanced coverage, particularly in new generation mobile communication systems operating on higher frequency bands, where propagation loss is greater and coverage radius is smaller.

Innovation Solution

The implementation involves a wireless communication method that receives first system information in a Synchronization Signal/Physical Broadcast Channel (PBCH) Block (SSB), which indicates an offset with defined value ranges, and determines the reception configuration of downlink control for second system information based on these value ranges.

1Speed

If new generation mobile communication systems operate on higher frequency bands, then communication speed and capacity are improved, but propagation loss increases and coverage radius decreases

Engineering Contradiction:

Core Design Contradiction:

SpeedVSLoss of energy

Solution Approach 1:

The patent changes the frequency band parameter to higher frequencies to improve communication speed and capacity, while accepting the trade-off of increased propagation loss. The system adapts by using beamforming and specific reception configurations to mitigate the coverage reduction at higher frequencies.

Core Design Contradiction:

SpeedVSLength of stationary object

Solution Approach 1:

The system changes the operating frequency parameter to achieve higher communication speeds, while the coverage radius naturally decreases as a consequence. The patent addresses this by optimizing beamforming parameters and reception configurations to extend effective coverage despite the frequency-induced limitations.
