Solution Overview

Problem

Current mobile communication systems experience significant delays in uplink data transmission due to the negotiation procedures before actual data transmission, which becomes more pronounced as data rates increase, hindering efficient communication and throughput in high-speed data transfer scenarios like HSUPA.

Innovation Solution

A communication method and system where the mobile station adds uplink data to transmission requests or channel establishment requests, allowing for permissionless data transmission when the uplink communication state is of a certain quality, and includes features like data collision monitoring and retransmission timing notification to optimize data transmission efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional negotiation procedures are used for uplink data transmission, then transmission permission can be controlled, but call-setting delay increases significantly

Engineering Contradiction:

Improvetransmission permission controlVSAvoidcall-setting delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The mobile station performs preliminary actions by attaching uplink data to transmission requests or channel establishment requests before actual data transmission. This allows the base station to prepare permission decisions in advance, reducing the delay between data availability and transmission start.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention extracts the essential permission control function from the traditional multi-step negotiation process. By allowing the mobile station to attach data directly to requests and receive permission decisions more rapidly, the critical permission control function is separated from the time-consuming procedural steps.

Inventive Principle:

Principle #2Taking out (Extraction)

2Productivity

If data rate is increased for high-speed transmission, then throughput improves, but negotiation delay becomes more pronounced

Engineering Contradiction:

ImprovethroughputVSAvoidnegotiation delay

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

For high-speed data transmission scenarios, the mobile station attaches uplink data to transmission requests or channel establishment requests before actual data transmission begins. This preliminary action allows the base station to prepare permission decisions in advance, reducing the delay between data availability and transmission start, thereby minimizing the impact of high data rates on overall throughput.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention enables continuous useful action by allowing the mobile station to prepare and attach data to requests continuously, rather than waiting for completion of lengthy negotiation procedures. This maintains transmission readiness and reduces idle time during high-speed transmission scenarios.

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If permission-based transmission mode is used, then transmission control is maintained, but transmission speed is reduced

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The base station performs preliminary evaluation of transmission conditions and attaches permission decisions to the transmission request processing. This allows permission-based control to be maintained while reducing the time between request receipt and permission decision, thereby minimizing the impact on transmission speed.

AI summary

The present method adds uplink data to a transmission request sent to the base station from the mobile station for obtaining permission for data transmission, or to a channel establishment request sent from the mobile station to the base station for establishing a channel in order to send the transmission request therethrough. This makes it possible to suppress delay caused by negotiation prior to actual uplink data transmission as much as possible, thereby realizing efficient uplink data transmission, that is, improved throughput of uplink communication.
