Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the 5G mobile communication system, delivering content using a directional beam is inefficient compared to non-directional beams, and existing technologies like MBMS struggle to effectively manage content delivery to multiple terminal apparatuses with varying beam directions.
Innovation Solution
A communication apparatus and method that includes a communication unit for wireless communication, a control unit for managing content delivery using directional beams, and a notification unit for informing terminal apparatuses of beam transmission timing, allowing for coordinated content reception across multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If directional beams are used for communication in 5G mobile communication system, then spatial multiplexing capability is improved, but content delivery efficiency to multiple terminal apparatuses deteriorates
Solution Approach 1:
The patent segments the content delivery process by associating different beams with different programs and notifying terminals of beam transmission timing for each direction. This allows the system to maintain directional beam advantages while efficiently delivering content to multiple terminals by organizing delivery in segmented time-direction slots.
Solution Approach 2:
The patent implements dynamic beam management by notifying terminals of beam transmission timing information that changes based on directional requirements. The system dynamically switches between different directional beams for different programs, optimizing both spatial multiplexing and content delivery efficiency adaptively.
2Area of stationary object
If directional beams are swept for data transmission, then communication coverage is improved, but coordination complexity for content reception increases
Solution Approach 1:
The patent applies preliminary action by notifying terminal apparatuses in advance of beam transmission timing information before actual content delivery. Terminals receive notification of which beams will be transmitted in which directions and when, allowing them to prepare for reception without increasing real-time coordination complexity.
Solution Approach 2:
The system uses feedback mechanisms where terminals report their reception status and the base station adjusts beam transmission timing accordingly. This feedback loop optimizes the balance between coverage area and coordination complexity by adapting to actual terminal needs.
