Base Station ACK Threshold Control for Data-Responsive Signaling

Solution Overview

Problem

Existing communication methods in 5G networks face challenges in managing acknowledgement (ACK) packets, leading to inefficient resource use and delayed data reception due to excessive ACK transmission, particularly when data amounts are small.

Innovation Solution

A base station device determines an accumulation threshold for ACK packets based on the transmitted data amount, transmitting this threshold to the terminal device to manage ACK accumulation and discard excess packets, employing a hybrid discard method to optimize ACK transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the number of ACKs transmitted is increased to ensure reliable communication, then communication reliability is improved, but communication resources are consumed and communication speed is reduced

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidcommunication speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent changes the parameter of ACK transmission by introducing an accumulation threshold value. Instead of transmitting ACKs immediately for every received packet, the terminal accumulates ACKs up to the threshold value before transmission. This parameter change allows the system to maintain reliability (by still transmitting ACKs) while reducing the frequency of transmissions and improving communication speed.

2Loss of energy

If ACK accumulation threshold is set high to reduce ACK transmission frequency, then resource consumption is reduced, but data reception delay increases when data amount is small

Engineering Contradiction:

Improveresource consumptionVSAvoiddata reception delay

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

The patent makes the ACK accumulation threshold dynamic by setting it based on the downlink data amount. When the data amount is large, a higher threshold is used to reduce ACK transmission frequency. When the data amount is small, a lower threshold is used to avoid delay. This dynamic adjustment resolves the contradiction between resource consumption and data reception delay.

3Productivity

If ACKs are discarded to reduce transmission number, then communication resource efficiency is improved, but data reception reliability may be compromised
