Solution Overview

Problem

In wireless communication systems, particularly at cell edges, the quality of service is compromised due to lower signal strength and higher interference levels, which existing CoMP schemes struggle to address effectively for latency-dependent and low-uplink activity communications like VoLTE or video streaming.

Innovation Solution

An eNodeB dynamically selects between battery-saving and throughput-enhancement modes for uplink CoMP based on the communication type, using pre-defined data-usage classes and QoS indicators to optimize power usage and throughput, thereby enhancing service quality for specific applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If CoMP schemes are implemented to improve signal strength and reduce interference at cell edges, then quality of service is improved, but power consumption increases and throughput is not enhanced for latency-dependent communications

Engineering Contradiction:
Improvequality of serviceVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic selection of CoMP enhancement modes based on communication type. The eNodeB determines whether a UE is engaged in latency-dependent communications (e.g., VoLTE, video streaming) or throughput-dependent communications, and dynamically switches between battery-saving mode and throughput-enhancement mode accordingly. This dynamic adaptation resolves the contradiction by activating CoMP only when it provides genuine quality of service improvement without unnecessary power consumption.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of CoMP based on communication characteristics. By modifying the enhancement mode parameter (battery-saving vs. throughput-enhancement) according to the determined communication type, the system optimizes the balance between power consumption and quality of service improvement for different application scenarios.

2Reliability

If CoMP schemes are implemented to improve signal strength and reduce interference at cell edges, then quality of service is improved, but uplink throughput does not improve for latency-dependent communications

Engineering Contradiction:
Improvequality of serviceVSAvoiduplink throughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system dynamically adjusts CoMP enhancement modes based on communication type determination. For latency-dependent communications, the battery-saving mode is selected which maintains quality of service without forcing unnecessary throughput enhancement. For throughput-dependent communications, the throughput-enhancement mode is activated. This dynamic behavior resolves the contradiction by aligning CoMP operation with actual communication requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The enhancement mode parameter is changed based on communication type. The system transitions between battery-saving mode (for latency-dependent communications where throughput improvement is unnecessary) and throughput-enhancement mode (for communications that benefit from increased throughput), thereby optimizing the balance between quality of service and uplink throughput for different application scenarios.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If throughput-enhancement mode is used for uplink CoMP, then uplink throughput is improved, but power consumption increases unnecessarily for latency-dependent communications

Engineering Contradiction:
Improveuplink throughputVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The enhancement mode parameter is dynamically changed based on communication type determination. When latency-dependent communications are detected (such as VoLTE or video streaming), the system switches to battery-saving mode, avoiding unnecessary throughput enhancement and associated power consumption. When throughput-dependent communications are detected, the system switches to throughput-enhancement mode. This parameter adaptation resolves the contradiction by matching power consumption levels to actual communication needs.

AI summary

Methods and systems are disclosed that can help to select an enhancement mode for uplink coordinated multipoint (CoMP). An exemplary method involves: 9a) determining, from a plurality of possible communication types, a communication type of a communication associated with a first user equipment (UE), wherein the first UE is capable of uplink CoMP communication via an access network; (b) based at least in part on the determined communication type, selecting either a battery-saving mode or a throughput-enhancement mode as an uplink CoMP enhancement mode for the first UE; and (c) providing uplink CoMP service to the first UE according to the selected mode.
