Solution Overview

Problem

Current relay terminal designs only combine the relay protocol layer with Layer 3 or Layer 2, lacking specific operation modes that optimize resource utilization, leading to reduced operation efficiency and processing capability.

Innovation Solution

The proposed wireless communication method allows a remote terminal to indicate the required relay service mode to a relay terminal, which then determines the appropriate service mode based on the message, enabling efficient relay services and optimizing resource management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the relay terminal uses a generic relay protocol layer combination (Layer 3 or Layer 2), then the remote terminal can access the network via the relay terminal, but the operation efficiency and processing capability of the relay terminal are reduced due to lack of specific operation mode design

Engineering Contradiction:
Improveoperation efficiencyVSAvoidrelay protocol layer complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the relay service into two distinct modes: Mode 1 for uplink data forwarding and Mode 2 for downlink message forwarding only. This segmentation allows the relay terminal to select the appropriate mode based on actual service requirements, avoiding the overhead of maintaining full Layer 3 functionality when only Layer 2 is needed, thereby improving operation efficiency while managing complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic mode switching capability where the relay terminal can transition between Mode 1 and Mode 2 based on service requirements indicated by the remote terminal. This dynamic adaptation allows the system to optimize resource utilization in real-time, improving productivity by activating only the necessary functional components for each specific service scenario.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the relay terminal maintains full relay protocol functionality for all service scenarios, then all types of relay services can be supported, but resources of the relay terminal are wasted due to unnecessary functions being activated

Engineering Contradiction:
Improverelay service coverageVSAvoidresource utilization efficiency
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent applies local quality by configuring different functional capabilities in different parts of the relay operation. In Mode 1, the relay terminal provides full uplink data forwarding capability, while in Mode 2, it provides only downlink message forwarding capability. This localized functional differentiation ensures that resources are allocated precisely where needed, improving adaptability without wasting energy on unnecessary functions.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes the operational parameters of the relay terminal based on the selected mode. When Mode 2 is selected, the relay terminal modifies its parameter set to exclude uplink data forwarding functions, thereby reducing resource consumption while maintaining the necessary downlink message forwarding capability. This parameter adjustment resolves the contradiction between versatility and resource efficiency.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the relay terminal processes all downlink messages and uplink data, then complete communication functionality is provided, but the processing capability is reduced due to handling unnecessary data

Engineering Contradiction:
Improvecommunication completenessVSAvoidprocessing capability
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent extracts and separates the downlink message forwarding function from the uplink data forwarding function. In Mode 2, only the essential downlink message forwarding capability is retained and activated, while uplink data processing is excluded. This extraction ensures communication reliability for paging and system information while improving processing capability by eliminating unnecessary uplink data handling overhead.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A wireless communication method and a terminal are provided. The method includes: transmitting, by a remote terminal, a first message indicating that a relay service mode required by the remote terminal is a first service mode and/or a second service mode. With the first message, a relay terminal is enabled to determine the relay service mode required by the remote terminal, such that the relay terminal can provide a relay service for the remote terminal based on the first service mode or the second service mode indicated in the first message and the remote terminal can access a network via the relay terminal. In addition, the service mode of the relay terminal can be managed according to the service requirements of the remote terminal, such that the operation efficiency and processing capability of the relay terminal can be improved without wasting the resources of the relay terminal.
