Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current New Radio (NR) systems are unable to support multiple numerologies simultaneously, limiting their ability to efficiently handle diverse wireless communication scenarios such as enhanced mobile broadband, massive machine-type communications, and ultra-reliable low latency communications.
Innovation Solution
A method and apparatus for configuring multiple data subband sets within a carrier, allowing user equipment (UE) to communicate with a base station using sets of consecutive physical resource blocks (PRBs) across different numerologies, enabling simultaneous support of various numerologies through semi-static frequency division multiplexing and dynamic scheduling mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different numerologies are supported simultaneously in NR systems, then the system's adaptability to diverse wireless communication scenarios is improved, but the device complexity and resource management difficulty increase
Solution Approach 1:
The patent divides the carrier bandwidth into multiple data subband sets, where each subband set is associated with a specific numerology. This segmentation allows different numerologies to be handled independently within their respective subbands, reducing the complexity of simultaneous multi-numerology management while maintaining adaptability to diverse communication scenarios.
Solution Approach 2:
The patent introduces a new dimension of organization by associating control resource sets (CORESETs) with specific data subband sets. This dimensional separation allows the system to manage multiple numerologies through distinct control-data associations, simplifying the overall system complexity while enabling versatile support for different numerologies.
2Adaptability or versatility
If multiple data subband sets are configured within a carrier, then the system's capability to handle diverse scenarios is improved, but the resource allocation complexity increases
Solution Approach 1:
The patent creates a universal framework where control resource sets can be associated with multiple data subband sets, and data subband sets can be linked to different numerologies. This multi-functional association mechanism allows the same control resource set to serve multiple purposes across different numerologies, reducing configuration complexity while enhancing system capability.
Solution Approach 2:
The patent enables dynamic association between control resource sets and data subband sets, allowing the system to flexibly configure and reconfigure resources based on varying communication scenarios. This dynamic association mechanism simplifies resource management by allowing adaptive allocation rather than static configuration.
3Adaptability or versatility
If semi-static frequency division multiplexing is used to support multiple numerologies, then the system flexibility is improved, but the scheduling complexity increases
Solution Approach 1:
The patent segments the frequency spectrum into multiple data subband sets, each dedicated to specific numerologies. This segmentation enables semi-static frequency division multiplexing by clearly defining which subbands are allocated to which numerologies, reducing scheduling complexity while maintaining system flexibility for supporting multiple numerologies simultaneously.

AI summary
A method and apparatus for configuring a data subband set in a wireless communication system is provided. A user equipment (UE) configures at least one data subband set within a carrier, and communicating with a base station by using the at least one data subband set. Each of the at least one data subband set consists of at least one data subband, and each of the at least one data subband consists of a set of consecutive physical resource blocks (PRBs). Each of the at least one data subband set may be configured per numerology. The at least one data subband may correspond to at least one bandwidth part (BWP).
