Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication systems face significant transmission delays due to inefficient allocation of physical uplink shared channel (PUSCH) resources, particularly for terminals in idle or inactive states, leading to suboptimal communication quality and resource wastage.

Innovation Solution

Implementing a traffic prediction function in terminals to predict uplink and downlink traffic, allowing for proactive allocation of PUSCH resources based on predicted traffic conditions, including reporting buffer status and initiating RRC connections as needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If PUSCH resources are pre-allocated to terminals regardless of data presence, then transmission delay is reduced, but resource wastage increases

Engineering Contradiction:

Improvetransmission delayVSAvoidresource wastage

Core Design Contradiction:

Loss of timeVSLoss of energy

Solution Approach 1:

The terminal predicts future traffic patterns and proactively requests PUSCH resources in advance before actual data transmission occurs. This preliminary action allows the base station to allocate resources ahead of time, reducing transmission delay when data becomes available, while the prediction mechanism ensures resources are only allocated when actually needed, avoiding wastage.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If terminals in idle or inactive state establish RRC connection to transmit uplink data, then data transmission becomes possible, but transmission delay increases

Engineering Contradiction:

Improvedata transmission capabilityVSAvoidtransmission delay

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

Terminals in idle or inactive states use traffic prediction to anticipate future data transmission needs and proactively establish RRC connections before actual data becomes available. This preliminary connection establishment eliminates the delay that would otherwise occur when needing to establish connections reactively upon data arrival.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If terminal reports buffer status periodically, then base station can allocate PUSCH resources, but transmission delay occurs until resources are allocated

Engineering Contradiction:

Improveresource allocation efficiencyVSAvoidtransmission delay

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

Instead of periodically reporting buffer status and waiting for resource allocation, the terminal uses traffic prediction to forecast future buffer status and proactively requests PUSCH resources in advance. This transforms the reactive resource allocation process into a proactive one, significantly reducing transmission delay while maintaining efficient resource utilization.

Inventive Principle:

Principle #10Preliminary action

AI summary

An operation method of a terminal in a communication system may comprise: predicting traffic using a traffic prediction function configured according to traffic prediction configuration information; transmitting a buffer prediction status report including a traffic prediction result to a base station; receiving a first physical uplink shared channel (PUSCH) resource allocation information generated based on the buffer prediction status report; and transmitting data to the base station using first resources allocated by the first PUSCH resource allocation information.
