Uplink Grant Resource Skipping for Spectral Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in managing resource allocation for uplink channels, particularly in scenarios where certain resources are unnecessary or redundant, leading to suboptimal utilization of bandwidth and power.
Innovation Solution
The implementation of a method and apparatus that allows user equipment (UE) and network entities to selectively skip or utilize specific frequency and time resources within a grant for uplink channels, based on indicated skipped or non-skipped resources, enabling more efficient resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE transmits using all granted resources, then the communication can be reliably received, but spectral efficiency deteriorates and power consumption increases due to unnecessary resource usage
Solution Approach 1:
The patent segments the granted resources into skipped resources and non-skipped resources. The UE transmits UCI to indicate which resources should be skipped, allowing the network to receive communications only on the non-skipped resources. This segmentation enables the system to maintain communication reliability on essential resources while improving spectral efficiency by excluding unnecessary resources from transmission.
Solution Approach 2:
The patent extracts unnecessary resources from the granted resource set by identifying and marking them as skipped resources. The UE selectively indicates which resources to skip through UCI transmission, effectively removing redundant resources from the transmission spectrum. This extraction improves spectral efficiency while the network maintains reliability by receiving communications only on the remaining non-skipped resources.
2Reliability
If the UE transmits using all granted resources, then the communication can be reliably received, but power consumption increases due to unnecessary transmission
Solution Approach 1:
The patent segments the granted resources into skipped and non-skipped portions. By transmitting UCI to indicate skipped resources, the UE enables the network to receive communications only on necessary resources. This segmentation reduces power consumption by eliminating transmissions on unnecessary resources while preserving communication reliability on the essential non-skipped resources.
Solution Approach 2:
The patent extracts unnecessary resources from the transmission spectrum by identifying and marking them as skipped. The UE uses UCI to indicate which resources should be excluded, allowing the network to receive communications only on non-skipped resources. This extraction reduces power consumption by preventing transmissions on redundant resources while maintaining reliability on essential communications.
3Productivity
If the UE indicates skipped resources through UCI, then spectral efficiency improves, but the complexity of resource management increases
Solution Approach 1:
The patent implements a feedback mechanism where the UE transmits UCI to indicate skipped resources to the network. This feedback loop enables the network to receive communications only on non-skipped resources, improving spectral efficiency. The feedback mechanism, while adding some complexity, provides a structured approach to resource management that balances efficiency gains with implementable complexity.
4Quantity of substance
If the network receives communications on all granted resources, then all potential data can be transmitted, but resource utilization deteriorates due to unnecessary resource consumption
Solution Approach 1:
The patent segments the granted resources into skipped and non-skipped portions based on UE indication through UCI. The network receives communications only on non-skipped resources, improving resource utilization by excluding unnecessary resources. This segmentation maintains data transmission capacity on essential resources while preventing waste on redundant resources, thereby improving overall productivity.
Solution Approach 2:
The patent extracts unnecessary resources from the transmission spectrum by identifying and marking them as skipped through UE feedback. The network receives communications only on non-skipped resources, improving resource utilization by removing redundant resources from the transmission mix. This extraction maintains necessary data transmission capacity while significantly improving resource utilization efficiency.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a grant for a physical uplink channel. The UE may select skipped resources that include one or more of frequency resources or time resources in the grant to skip for a communication on the physical uplink channel. The UE may transmit uplink control information (UCI) that indicates the skipped resources or non-skipped resources of the grant. The UE may transmit the communication using the non-skipped resources and not the skipped resources. Numerous other aspects are described.
