Solution Overview

Problem

In next-generation radio communication systems like NR, the implementation of BWP-based control poses challenges in identifying blank resources, leading to potential declines in communication throughput and spectral efficiency.

Innovation Solution

A user terminal is equipped with a control section that selects and configures blank resource regions associated with bandwidth parts (BWP), allowing for proper identification and utilization of these resources to enhance communication efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If BWP-based control is implemented, then resource allocation flexibility is improved, but identification of blank resources becomes difficult

Engineering Contradiction:
Improveresource allocation flexibilityVSAvoididentification of blank resources
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies preliminary action by pre-configuring blank resource regions before data transmission. The base station determines and notifies the terminal of blank resource regions in advance through RRC signaling or DCI, allowing the terminal to identify these regions without complex detection processes during actual data reception, thus resolving the contradiction between flexibility and identification difficulty

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses signaling mechanisms (RRC signaling and DCI) as intermediaries to transmit information about blank resource regions from the base station to the terminal. This intermediary approach allows the terminal to obtain blank resource information indirectly through standardized signaling channels, simplifying the identification process while maintaining BWP-based control flexibility

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of energy

If BWP-based control is implemented, then spectral efficiency can be improved, but communication throughput may decline

Engineering Contradiction:
Improvespectral efficiencyVSAvoidcommunication throughput
Core Design Contradiction:
Loss of energyVSProductivity

Solution Approach 1:

The patent extracts blank resource regions from the total available resources within BWPs. By identifying and separating these blank regions (which are not used for data transmission), the system can optimize resource allocation for actual data transmission, improving spectral efficiency while preventing throughput decline by ensuring data is transmitted only in non-blank regions

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies local quality by treating blank resource regions differently from regular resource regions. Within the BWP structure, specific local regions are identified as blank and excluded from data transmission, allowing optimized resource utilization in the remaining regions. This local differentiation improves overall spectral efficiency while maintaining throughput by focusing transmission resources effectively

Inventive Principle:
Principle #3Local quality

AI summary

A terminal is disclosed including a receiver that receives configuration information; and a processor that controls receiving processes for Physical Downlink Shared Channel (PDSCH), wherein the processor controls the receiving processes for the PDSCH under an assumption that the PDSCH is not allocated in a first reserved resource corresponding to the first configuration information, when the receiver receives first configuration information about a Bandwidth part (BWP)-specific reserved resource as the configuration information, and controls the receiving processes for the PDSCH under an assumption that the PDSCH is not allocated in a second reserved resource corresponding to the second configuration information, when the receiver receives second configuration information about a cell-specific reserved resource as the configuration information. In other aspects, an apparatus and a system are also disclosed.
