LTE-A Resource Block Sorting for Terminal Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the LTE-A system, some PRB resources are configured as unavailable to LTE terminals, leading to resource allocation conflicts and congestion when using sorting methods similar to those in the LTE system, making it difficult for LTE-A terminals to be compatible with LTE terminals.
Innovation Solution
A resource allocation method that sorts RBs used by LTE and LTE-A terminals based on their specific use situations, ensuring compatibility by aligning PRB resources and adjusting RBG sizes and subsets to prevent conflicts and waste, allowing for seamless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If PRB resources are sorted similarly to LTE system RBs and RB grouping or hopping mapping is performed, then resource allocation can be performed on PRB resources, but conflict and congestion occur at the time of allocating LTE and LTE-A resources, making LTE-A terminals incompatible with LTE terminals
Solution Approach 1:
The patent divides the PRB resources into two separate sorting sequences: one for LTE terminals and another for LTE-A terminals. This segmentation prevents resource allocation conflicts by ensuring that LTE and LTE-A resources are sorted and allocated independently, thus maintaining compatibility between the two terminal types while avoiding congestion in the resource allocation process.
2Adaptability or versatility
If some PRB resources are configured as unavailable to LTE terminals to support LTE-A features, then LTE-A system features and flexibility are supported, but resource allocation conflicts occur when using sorting methods similar to LTE system
Solution Approach 1:
The patent segments the resource allocation process by creating separate sorting sequences for LTE and LTE-A terminals. This allows the network to configure unavailable PRB resources for LTE terminals while maintaining reliable resource allocation for both terminal types through independent sorting, thus preserving both LTE-A flexibility and allocation reliability.
Solution Approach 2:
The patent introduces an intermediary sorting mechanism that acts as a mediator between LTE and LTE-A resource allocation. By implementing separate sorting sequences that are then coordinated during resource allocation, the system resolves conflicts between LTE-A feature support and reliable resource allocation for both terminal types.
3Productivity
If all PRB resources are sorted uniformly like LTE RBs, then sorting and allocation can be performed, but resource waste and conflicts occur due to different terminal requirements
Solution Approach 1:
The patent segments the PRB resource sorting into terminal-type-specific sequences, preventing resource waste by ensuring that resources are allocated according to the specific requirements of each terminal type. This segmentation eliminates the inefficiency of uniform sorting that causes resource conflicts and waste.
Solution Approach 2:
The patent applies local quality by tailoring the sorting sequence to the specific needs of different terminal types. Instead of a uniform sorting approach, the system implements differentiated sorting sequences that optimize resource allocation for each terminal type, thereby eliminating resource waste while maintaining high allocation efficiency.
Data Source
AI summary
A resource allocation method, a network device and a wireless system are disclosed. The method includes: sorting Resource Blocks (RBs) used by a terminal of a first system and a terminal of a second system according to a use situation of the RBs used by the terminal of the first system and the terminal of the second system; and allocating the sorted RBs. When some RBs are available to a Long Term Evolution (LTE) terminal, coexistence of an LTE-Advanced (LTE-A) terminal and the LTE terminal is enabled, and compatibility between the LTE-A terminal and the LTE terminal is ensured.
