Solution Overview

Problem

Existing wireless downlink communication systems face inefficiencies due to unnecessary power consumption when resources are underutilized, particularly during periods of low throughput, leading to redundant input power drawn to amplify unutilized frequencies or time windows.

Innovation Solution

A resource redistribution mechanism that reallocates frequency resources and adjusts transmission power budgets for users, allowing for modified frequency ranges and modulation coding schemes to optimize throughput and minimize input power by utilizing symbol blanking techniques.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If frequency resources are allocated to multiple users in wireless downlink communication, then user coverage and service capability are improved, but input power consumption increases due to amplification of unutilized frequencies

Engineering Contradiction:

Improveuser coverageVSAvoidinput power consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent changes the frequency allocation parameters dynamically based on actual user throughput needs. By adjusting which frequency resources are allocated to which users in different time windows, the system ensures that transmission circuits only amplify frequencies that are actually being used, eliminating waste of input power on unutilized frequencies while maintaining comprehensive user coverage.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If transmission power budget is allocated to all users, then communication service is maintained for all users, but power efficiency decreases when some users have low throughput

Engineering Contradiction:

Improvecommunication service availabilityVSAvoidpower efficiency

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements dynamic power budget allocation that adjusts in real-time based on user throughput conditions. When a user experiences low throughput, the system dynamically reduces or reassigns their allocated power budget, ensuring that power is concentrated on users with active communication needs. This maintains reliable service for all users while preventing energy waste on users with minimal data transmission requirements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system periodically reevaluates user throughput and reallocates power budgets in time windows. This periodic adjustment mechanism allows the system to adapt to changing user needs, maintaining service availability while optimizing power efficiency by cycling through different allocation configurations based on actual utilization patterns.

Inventive Principle:

Principle #19Periodic action

3Duration of action of stationary object

If frequency resources are continuously allocated to users, then uninterrupted communication is achieved, but power consumption increases during low throughput periods

Engineering Contradiction:

Improvecommunication continuityVSAvoidinput power

Core Design Contradiction:

Duration of action of stationary objectVSUse of energy by moving object

Solution Approach 1:

The patent segments the continuous frequency allocation into discrete time-window-based allocations. By dividing the communication timeline into separate windows and allocating frequencies selectively to different users in different windows, the system maintains communication continuity for each user while avoiding the power consumption associated with continuously allocating frequencies to all users simultaneously, especially during low throughput periods.

Inventive Principle:

Principle #1Segmentation

AI summary

There is provided an apparatus and a method. The apparatus is provided with receiving circuitry to receive, for each of a plurality of users, an initial resource allocation comprising an allocation of frequency resources to be used in a communication over a wireless downlink connection. The apparatus is also provided with transmission power budget allocation circuitry to allocate a portion of a total transmission power budget to each of the plurality of users. The apparatus is also provided with scheduling circuitry to perform a resource redistribution to obtain a revised resource allocation based on the portion of the total transmission power budget allocated to each of the plurality of users, the revised resource allocation comprising, for at least one user of the plurality of users, a modified frequency allocation corresponding to a different range of frequencies than the allocation of frequency resources comprised in the initial resource allocation.
