Solution Overview

Problem

In New Radio (NR) systems like 5G, reserved resources for uplink channels or signals often result in numerous resource fragments that are not utilized by other channels, leading to low resource utilization rates.

Innovation Solution

A communication method where a terminal uses resource fragments indicated by a network device to transmit uplink channels or signals, avoiding reserved resources and improving resource utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the base station reserves resources for transmitting a certain uplink channel or uplink signal, then the transmission reliability of the original uplink channel or signal is improved, but resource utilization rate deteriorates due to unused resource fragments

Engineering Contradiction:
Improvetransmission reliabilityVSAvoidresource utilization rate
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent segments the originally reserved uplink resources into two parts: resources occupied by the first uplink channel/signal and remaining resource fragments. These fragmented resources are then independently allocated to second uplink channels/signals, transforming a single reserved resource block into multiple usable resource units, thereby improving overall resource utilization while maintaining the integrity of original transmissions

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent enables resource fragments to serve multiple purposes: they continue to support the original uplink channel/signal transmission while simultaneously being allocated to additional uplink channels/signals. This multi-functional use of resource fragments resolves the contradiction between ensuring reliable original transmissions and improving resource utilization efficiency

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If resource fragments are not used by other channels, then transmission interference is avoided, but resource waste occurs leading to low resource utilization

Engineering Contradiction:
Improvetransmission stabilityVSAvoidresource waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent applies local quality by selectively allocating resources based on specific conditions: resource fragments are allocated to second uplink channels/signals only when they do not overlap with resources occupied by the first uplink channel/signal. This localized, condition-based allocation ensures that each resource unit is used appropriately without causing transmission interference, thereby maintaining transmission stability while reducing resource waste

Inventive Principle:
Principle #3Local quality

AI summary

The present application provides a communication method, a terminal, and a network device. The communication method in the present application comprises: a terminal receives first indication information sent by a network device, the first indication information being used for indicating a first resource; and the terminal sends, according to the first indication information, an uplink channel or an uplink signal to the network device by using a third resource within the second resource, the third resource being a resource that is located in the second resource and that is not overlapped with the first resource. The communication method, the terminal and the network device provided in the present application can flexibly improve the utilization rate of resources.
