Solution Overview

Problem

Current communication systems face challenges in efficiently managing reference information across multiple cells or carriers, particularly in terms of channel quality indicator reporting and cell configuration, which affects data transmission rates and system capacity.

Innovation Solution

A method and apparatus that send reference information associated with different cells or carriers to distinct destinations at specific time intervals, using control channels and scrambling information to determine cell associations, and allow for discontinuous transmission upon cell deactivation, enabling efficient reconfiguration and resource management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If reference information for multiple cells or carriers is transmitted simultaneously to the same destination, then the system can maintain simpler transmission structure, but the channel quality indicator reporting becomes inefficient and system capacity is reduced

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidtransmission structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the transmission of reference information by dividing multiple cells/carriers into different time intervals and assigning them to different destinations. This segmentation allows efficient channel quality indicator reporting for each cell while maintaining overall system capacity, resolving the contradiction between transmission efficiency and structural simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces time as an additional dimension for transmission differentiation. Instead of transmitting all reference information simultaneously in a single time slot, the system distributes transmissions across multiple time intervals, enabling more efficient use of transmission resources and improving system capacity without requiring complex simultaneous multi-destination architecture.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If continuous reference information transmission is maintained for all cells, then channel quality monitoring remains stable, but resource allocation efficiency decreases when cells are deactivated

Engineering Contradiction:
Improvechannel quality monitoring stabilityVSAvoidresource allocation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements periodic transmission of reference information, where cells that are deactivated stop transmitting their reference information during certain time intervals. This periodic action allows the system to maintain channel quality monitoring stability for active cells while improving resource allocation efficiency by eliminating redundant transmissions from deactivated cells, thus resolving the contradiction between monitoring stability and resource efficiency.

Inventive Principle:
Principle #19Periodic action

3Loss of time

If all cells transmit reference information at the same time interval, then the transmission schedule becomes simpler, but latency increases due to inefficient processing

Engineering Contradiction:
Improvetransmission latencyVSAvoidtransmission scheduling complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent segments the transmission schedule by assigning different time intervals to different cells or carriers. This segmentation allows the system to process and transmit reference information more efficiently, reducing latency by avoiding simultaneous transmissions that would create processing bottlenecks, while the scheduling complexity is managed through systematic time-slot assignment.

Inventive Principle:
Principle #1Segmentation

AI summary

A method includes causing first reference information associated with a first cell or carrier and second reference information associated with a second cell or carrier to be sent to a first destination in a first time interval and causing at least third reference information associated with a third cell or carrier to be sent to a second destination in a different time interval.
