Uplink Resource Mapping Across Terrestrial and Satellite Cells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication systems face challenges in efficiently managing resource allocation in multi-connection scenarios involving terrestrial and satellite cells, leading to suboptimal Quality of Service (QoS) and user experience.
Innovation Solution
A method for resource configuration that determines a mapping relationship between QoS parameter identifiers, logical channel identifiers, or bearer identifiers with cell type identifiers or cell identifier lists, and performs buffer status reports (BSR) and uplink resource allocations based on these mappings to ensure appropriate resource usage by different cell types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal device accesses multiple cell types simultaneously (terrestrial and satellite cells), then the coverage and service availability are improved, but the resource allocation complexity and difficulty of managing QoS increase
Solution Approach 1:
The patent segments the resource pool by establishing separate mapping relationships for different cell types. Each cell type (terrestrial or satellite) has its own resource allocation rules and QoS parameters, allowing the terminal device to manage resources independently for each cell type while accessing multiple cells simultaneously. This segmentation reduces the overall complexity by breaking down the multi-cell resource management into manageable per-cell-type components.
2Reliability
If resource allocation is optimized for specific cell types, then the QoS for services in those cells is improved, but the overall system complexity increases due to multiple mapping relationships
Solution Approach 1:
The patent applies local quality by configuring different mapping relationships tailored to the specific characteristics of each cell type. Terrestrial cells may use one mapping configuration optimized for ground-based network characteristics, while satellite cells use another mapping configuration optimized for space-based communication characteristics. This allows QoS to be optimized locally for each cell type while maintaining a systematic approach through standardized mapping relationship structures.
3Productivity
If the terminal device performs detailed buffer status reports and uplink resource allocations for each cell type, then the resource utilization efficiency is improved, but the signaling overhead and processing time increase
Solution Approach 1:
The patent implements preliminary action by pre-configuring the mapping relationships between QoS parameters, logical channel identifiers, bearers, and cell types before actual data transmission begins. The network device provides these mapping configurations in advance through RRC signaling or other configuration mechanisms. This allows the terminal device to perform efficient buffer status reports and resource allocations without needing to compute complex mappings in real-time, thereby reducing processing time while maintaining high resource utilization efficiency.

AI summary
A method for resource configuration, performed by a terminal device, includes: determining a first mapping relationship between a first target identifier and a second target identifier, in which the first target identifier includes at least one of: a Quality of Service (QoS) parameter identifier, a logical channel identifier or a bearer identifier; and the second target identifier includes at least one of: a cell type identifier or a cell identifier list; and performing a buffer status report (BSR) and/or an uplink resource allocation based on the first mapping relationship.
