Solution Overview

Problem

As mobile devices support multiple frequency bands, the amount of information required to report compressed mode requirements becomes inefficient, leading to a wastage of limited communication bandwidth in telecommunications systems.

Innovation Solution

A method and apparatus that utilize a multi-band information element to streamline the communication of compressed mode requirements, allowing a single Boolean expression to indicate the need for compressed mode across all measurements, reducing the data volume and enhancing bandwidth utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If separate information elements are used to report compressed mode requirements for each frequency band, then the network can obtain detailed band-specific measurement capabilities, but the data volume increases and communication bandwidth is wasted

Engineering Contradiction:
Improvecompressed mode requirement informationVSAvoiddata volume
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent merges multiple band-specific compressed mode requirement information elements into a single multi-band information element. Instead of reporting separate Boolean values for each frequency band, the UE now reports a unified indication that covers all bands, thereby reducing the total data volume while preserving the essential compressed mode capability information needed by the network.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The multi-band information element is designed to serve multiple frequency bands simultaneously with a single report. This universal approach allows the same information element to convey compressed mode requirements across all supported bands, eliminating the need for band-specific redundant reporting and optimizing bandwidth utilization.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If detailed band-specific compressed mode requirements are reported, then the network can optimize measurements for each band, but the communication bandwidth efficiency decreases

Engineering Contradiction:
Improvemeasurement capability reporting accuracyVSAvoidbandwidth utilization efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

By combining multiple band-specific reports into a single multi-band information element, the patent maintains the reliability of measurement capability reporting while improving bandwidth utilization efficiency. The network receives sufficient information to optimize measurements across all bands without the overhead of separate detailed reports for each band.

Inventive Principle:
Principle #5Merging (Combining)
