Wireless Resource Allocation Signaling for Reserved Resources
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
2Productivity
If reserved resources occupy entire slots, then resource allocation is simplified, but resource utilization efficiency decreases
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.
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.
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
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.

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.
