Solution Overview

Problem

Existing communication technologies face challenges in efficiently utilizing time and/or frequency resources when multiplexing terminal devices requiring different service scenarios, such as eMBB and URLLC, leading to potential resource wastage.

Innovation Solution

A method and device that determine a target transmission pattern from a set of candidate patterns, where each pattern includes DL and/or UL transmission parts with varying subcarrier spaces, to optimize resource utilization for communication between network devices and terminal devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If eMBB terminal device and URLLC terminal device are multiplexed in the same transmission pattern, then resource utilization improves, but user plane latency of eMBB increases significantly

Engineering Contradiction:

Improveresource utilizationVSAvoiduser plane latency

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

The transmission pattern is segmented into different types (first type for eMBB, second type for URLLC) with distinct characteristics. The network device selectively applies different transmission patterns to different terminal devices based on their service requirements, thereby avoiding latency conflicts while maintaining resource utilization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The network device dynamically selects transmission patterns based on real-time service requirements. For URLLC terminals requiring low latency, a second transmission pattern is chosen; for eMBB terminals, a first transmission pattern is selected. This dynamic adaptation resolves the contradiction between resource utilization and latency.

Principle #15Dynamics

2Area of stationary object

If UL transmission and DL transmission are configured in the whole bandwidth, then communication coverage improves, but resource utilization decreases due to waste

Engineering Contradiction:

Improvebandwidth coverageVSAvoidresource utilization

Core Design Contradiction:

Area of stationary objectVSLoss of energy

Solution Approach 1:

Different transmission patterns are applied to different frequency resources based on local requirements. The first transmission pattern with wider subcarrier spacing is applied to resources serving eMBB terminals, while the second pattern with narrower spacing is applied to resources serving URLLC terminals. This localized optimization improves overall resource utilization while maintaining full bandwidth coverage.
