Solution Overview

Problem

The challenge of efficiently adjusting time-frequency resources occupied by code block sets in wireless communication systems, particularly in 5G systems supporting XR services, has not been adequately addressed, leading to inefficiencies in resource utilization.

Innovation Solution

A method and apparatus that dynamically adjust the size of the target RE set based on conditions, including the number of bits in the code block set and priority of control information, ensuring optimal resource allocation by considering overlapping and priority levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a fixed RE set is allocated for code block sets, then resource allocation is simple, but resource utilization efficiency deteriorates

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidresource allocation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements dynamic resource element set selection by determining the target RE set based on the actual number of bits in the code block set. When the number of bits exceeds a first threshold, the first RE set is selected; when it exceeds a second threshold, the second RE set is selected. This dynamic adaptation resolves the contradiction by making resource allocation flexible rather than fixed, improving utilization efficiency while maintaining manageable complexity through threshold-based decision logic.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of RE set selection based on the number of bits in the code block set. By using the bit count as a determining parameter and comparing it against predefined thresholds, the system selects appropriate RE sets (first or second) to match the actual data volume. This parameter-driven approach improves resource utilization by matching allocation size to actual needs while keeping the allocation mechanism relatively simple.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If time-frequency resources are increased for code block sets, then transmission reliability is improved, but resource waste increases

Engineering Contradiction:
Improvetransmission reliabilityVSAvoidresource waste
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent adjusts the time-frequency resources (RE set size) based on the parameter of code block set bit count. When bits exceed the first threshold, the first RE set is used; when bits exceed the second threshold, the second RE set is used. This parameter-based adaptation ensures sufficient resources for reliable transmission when needed while avoiding resource waste when the data volume is small, thus resolving the contradiction between reliability and resource efficiency.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies partial resource allocation by selecting different RE sets based on actual needs. Rather than always allocating maximum resources, the system allocates partial resources (first or second RE set) appropriate to the code block size, ensuring adequate transmission reliability while minimizing resource waste through conditional allocation.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If multiple RE sets are configured for different code block set sizes, then resource allocation flexibility is improved, but system complexity increases

Engineering Contradiction:
Improveresource allocation flexibilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic RE set selection with multiple configured RE sets (first and second) that are chosen based on the code block set bit count. The system maintains multiple RE sets for flexibility but uses simple threshold comparisons to dynamically select the appropriate one, achieving adaptability while controlling complexity through rule-based selection logic.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the resource allocation space into multiple discrete RE sets (first RE set, second RE set) with different sizes. Each RE set is optimized for specific data volume ranges. By segmenting resources and using threshold-based selection, the system achieves flexible adaptation to different code block sizes while maintaining manageable complexity through clear segmentation boundaries.

Inventive Principle:
Principle #1Segmentation

AI summary

Disclosed in the present application are a method and apparatus used in a node for wireless communication. The method comprises: a first node receiving first signaling, wherein the first signaling is used for indicating a first RE set; and sending a first code block set in a target RE set, wherein the target RE set is the first RE set or a proper subset of the first RE set. The first RE set is reserved for the first code block set, and the first code block set includes at least one code block; and the target RE set is related to whether a first condition set is satisfied. When the first condition set is satisfied, the target RE set is the first RE set; and when the first condition set is not satisfied, the size of the target RE set depends on the number of bits included in the first code block set. The first condition set includes one or more conditions.
