Solution Overview

Problem

Conventional mobile communication systems lack efficient control methods for transmitting reception quality information from mobile station apparatuses to base station apparatuses, leading to inefficient use of uplink resources due to varying information amounts and transmission frequencies.

Innovation Solution

The system employs a mobile communication system where the base station apparatus allocates physical uplink shared channels or control channels for the mobile station apparatus to periodically transmit channel state information, using radio resource control signals to set transmission intervals and channels, allowing flexible adaptation to information amounts and frequencies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the mobile station apparatus transmits reception quality information frequently with large information amounts, then the base station apparatus can perform accurate resource allocation and transmission scheme determination, but the uplink resources are wasted due to excessive transmission frequency and information amount

Engineering Contradiction:

Improvereception quality information accuracyVSAvoiduplink resource waste

Core Design Contradiction:

Measurement precisionVSLoss of energy

Solution Approach 1:

The patent applies dynamics by making the transmission frequency and information amount of reception quality information variable rather than fixed. The base station apparatus dynamically adjusts the transmission parameters based on the actual channel state and service requirements, allowing the system to adapt between accurate measurement and resource conservation modes

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameters of reception quality information transmission by adjusting the transmission frequency and information amount according to different scenarios. The base station apparatus controls these parameters through downlink signals, enabling flexible adaptation to varying network conditions and service demands

Inventive Principle:

Principle #35Parameter changes

2Loss of energy

If the mobile station apparatus transmits reception quality information infrequently with small information amounts, then the uplink resources are conserved, but the base station apparatus cannot perform accurate resource allocation and transmission scheme determination

Engineering Contradiction:

Improveuplink resource efficiencyVSAvoidreception quality information accuracy

Core Design Contradiction:

Loss of energyVSMeasurement precision

Solution Approach 1:

The system dynamically adjusts transmission parameters based on real-time needs. When resources are constrained or channel conditions are stable, the transmission frequency and information amount are reduced to conserve uplink resources while maintaining adequate measurement accuracy through selective transmission

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The base station apparatus controls the transmission parameters (frequency and information amount) by changing them according to network conditions. This allows the system to optimize the balance between resource efficiency and measurement accuracy by adjusting parameters such as transmission interval and CQI report granularity

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If the base station apparatus uses fixed transmission parameters for reception quality information, then the system operation is simple, but the system cannot adapt to varying information amounts and transmission frequencies required for different service types

Engineering Contradiction:

Improvesystem operation simplicityVSAvoidservice type adaptability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamics by enabling the base station apparatus to flexibly adjust transmission parameters based on service type and channel conditions. Different service types (e.g., voice, data, video) can have different transmission frequencies and information amounts configured, allowing the system to adapt to varying requirements while maintaining operational simplicity through centralized control

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent applies universality by creating a unified control mechanism that handles multiple service types with varying requirements. The base station apparatus uses a single flexible framework to manage different service types (voice, data, video) with different transmission parameters, eliminating the need for separate fixed configurations for each service type

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A mobile communication system in which a mobile station apparatus transmits uplink data to a base station apparatus using a physical uplink shared channel that is allocated by an uplink data transmission permission signal, wherein the base station apparatus allocates, to the mobile station apparatus, by using a radio resource control signal, the physical uplink shared channel for the mobile station apparatus to transmit channel states information, and the mobile station apparatus periodically transmits, to the base station apparatus, the channel states information using the physical uplink shared channel.
