Solution Overview

Problem

Current wireless communication systems face inefficiencies in resource allocation due to the lack of clear identification of reserved resources, leading to increased overhead and computing resource usage when communicating with user equipment (UEs), especially when reserved resources do not occupy entire slots.

Innovation Solution

The system introduces signaling to identify reserved resources to UEs, allowing them to transmit or receive communications without using reserved resources by employing rate matching techniques, thereby reducing the number of resource allocations needed and improving resource allocation efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If reserved resources are not clearly identified to UEs, then resource allocation flexibility is maintained, but signaling overhead and computing resource usage increase

Engineering Contradiction:
Improvesignaling overheadVSAvoidresource allocation complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The network entity performs preliminary identification and signaling of reserved resources to UEs before actual resource allocation. By pre-configuring reserved resource information, the system avoids the need for complex real-time resource allocation negotiations, thereby reducing signaling overhead and computing resource usage during operation.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If reserved resources occupy entire slots, then resource allocation is simplified, but resource utilization efficiency decreases

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

Solution Approach 1:

The patent segments reserved resources from entire slots to specific resource elements within slots. By identifying reserved resources at the resource element level rather than slot level, the system allows partial slot utilization for other purposes while maintaining reserved resources, thereby improving resource utilization efficiency without significantly increasing allocation complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by allowing different portions of a slot to have different allocation characteristics. Reserved resource elements maintain their reserved status while other resource elements in the same slot can be dynamically allocated, creating local differentiation that improves overall resource utilization while managing complexity.

Inventive Principle:
Principle #3Local quality

3Measurement precision

If multiple resource allocations are used for overlapping resources, then resource precision is improved, but the number of resource allocations and overhead increases

Engineering Contradiction:
Improveresource allocation precisionVSAvoidnumber of resource allocations
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The network entity performs preliminary identification and signaling of reserved resources to UEs before actual resource allocation. By pre-configuring reserved resource information, the system avoids the need for complex real-time resource allocation negotiations, thereby reducing signaling overhead and computing resource usage during operation.

Inventive Principle:
Principle #10Preliminary action

AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive information identifying a reserved resource allocation, wherein the reserved resource allocation is associated with a reserved resource; receive information identifying another resource allocation, wherein the other resource allocation overlaps with the reserved resource allocation at an overlapped portion; and selectively perform a communication using the overlapped portion for the reserved resource allocation or the other resource allocation based at least in part on at least one of: respective traffic types of the reserved resource allocation and the other resource allocation, or respective priority levels associated with the reserved resource allocation and the other resource allocation. Numerous other aspects are provided.
