Uplink Data Operations for Multiple Numerologies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack a feasible solution for determining resources for uplink data transmission in scenarios with multiple numerologies, which are introduced in the 3GPP RAN 1, leading to challenges in managing different Quality of Service (QoS) demands for various services.
Innovation Solution
A method and device for a user equipment to determine an uplink grant and corresponding bearers based on correspondence relationships between numerologies and uplink grants, using network slice identifiers and QoS parameters, allowing for efficient allocation of resources and composition of uplink data packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple numerologies are introduced to support different services with different QoS demands, then service adaptability and QoS management capability are improved, but resource allocation complexity and system configuration complexity increase
Solution Approach 1:
The patent segments the resource allocation process by introducing separate mapping relationships: one mapping between numerology and uplink grant, and another mapping between numerology and bearer. This segmentation allows the system to handle multiple numerologies independently through standardized mapping mechanisms, reducing the overall complexity of resource allocation while maintaining support for diverse services with different QoS requirements
Solution Approach 2:
The patent introduces mapping relationships as intermediary layers between numerology and resource allocation. Instead of directly allocating resources for each numerology-service combination, the system uses uplink grant and bearer as intermediaries that bridge the numerology configuration with the actual resource allocation, simplifying the management of multiple numerologies
2Adaptability or versatility
If multiple numerologies are introduced for different services, then service diversity support is improved, but uplink data transmission implementation complexity increases
Solution Approach 1:
The patent establishes mapping relationships between numerology and uplink grant, and between numerology and bearer, in advance before actual data transmission occurs. These pre-configured mappings enable the user equipment to quickly determine the appropriate uplink grant and bearer for a given numerology without complex real-time decisions, simplifying the uplink data transmission process while supporting multiple services

AI summary
A method and a device for uplink data operations are provided to enable a user equipment to perform uplink data transmission for a numerology scenario. In embodiments of the present application, the user equipment determines uplink scheduling signaling according to a first correspondence between a numerology and the uplink scheduling signaling, determines a bearer according to a second correspondence between the numerology and the bearer, and performs an uplink data operation according to the uplink scheduling signaling and the bearer. In the present invention, since the user equipment can perform uplink data operations according to the first correspondence between the numerology and the uplink scheduling signaling and the second correspondence between the numerology and the bearer, the user equipment is able to perform uplink data operations for the numerology scenario, thus improving system performance.
