Solution Overview

Problem

Current mobile communication systems, particularly 4G, lack a solution for power control of resources during uplink beam management, which is essential for efficient beam management and transmission in future 5G systems.

Innovation Solution

A power control method is introduced where a network device configures and sends power control parameters to a terminal for uplink beam management resources, allowing the terminal to adjust transmission powers based on these parameters, ensuring consistent power control for SRS, PRACH, and PUCCH resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If power control parameters are configured for uplink beam management resources, then the quality of uplink beams is improved, but the device complexity increases

Engineering Contradiction:

Improvequality of uplink beamsVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by configuring specific power control parameters (P0, alpha, delta) for uplink beam management resources. These parameters enable dynamic adjustment of transmission power based on beam quality requirements, thereby improving uplink beam quality while maintaining manageable system complexity through standardized parameter configuration mechanisms.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If power control parameters are sent to terminal for each resource, then the transmission power control precision is improved, but the signaling overhead increases

Engineering Contradiction:

Improvetransmission power control precisionVSAvoidsignaling overhead

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

The patent segments power control parameters into different categories (P0, alpha, delta) and applies them to different resource types (SRS, PRACH, PUCCH) in the uplink beam management resource set. This segmentation allows precise power control for each resource while reducing signaling overhead by grouping similar parameters and using efficient configuration methods.

Inventive Principle:

Principle #1Segmentation

3Productivity

If power control is implemented for uplink beam management resources, then the efficiency of uplink beam management is improved, but the energy consumption increases

Engineering Contradiction:

Improveefficiency of uplink beam managementVSAvoidenergy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic power control for uplink beam management resources by configuring parameters that allow the terminal to adjust transmission power based on actual beam management requirements. This dynamic approach improves uplink beam management efficiency by allocating power only when and where needed, rather than using continuous high power transmission, thus balancing efficiency improvement with energy consumption management.
