Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications systems, data conflicts between different terminals occur due to inadequate resource configuration, leading to inefficient data transmission and resource utilization.
Innovation Solution
A method and apparatus for configuring reserved resource elements within resource units, comprising X resource blocks in the frequency domain and Y symbols in the time domain, with flexible configuration options for resource unit size, subcarrier spacing, and reserved-RE patterns to reduce signaling overheads and data conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resource configuration is increased to avoid data conflicts, then data transmission reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent uses reference signal patterns as templates to define reserved RE configurations. Instead of signaling each reserved RE individually, the network device signals a reference signal pattern index, and the terminal copies the reserved RE configuration from the corresponding reference signal pattern, significantly reducing signaling overhead while ensuring reliable data transmission
Solution Approach 2:
The patent makes reserved RE configurations universal by reusing reference signal patterns that are already defined in the system. The same reference signal pattern infrastructure serves dual purposes: providing reference signals for channel estimation and defining reserved RE patterns for data transmission, eliminating the need for separate signaling mechanisms
2Ease of manufacture
If resource unit size is fixed, then configuration simplicity is maintained, but resource utilization efficiency decreases
Solution Approach 1:
The patent introduces dynamic resource unit configuration where the size of resource units (number of RBs and symbols) can be flexibly adjusted based on terminal capabilities and channel conditions. The network device can configure different resource unit sizes for different terminals or different time-frequency resources, optimizing resource utilization while maintaining manageable configuration complexity through standardized configuration parameters
3Reliability
If reserved RE configuration is detailed, then data conflict reduction is improved, but signaling overhead increases
Solution Approach 1:
The patent uses reference signal patterns as templates to define reserved RE configurations. Instead of signaling each reserved RE individually, the network device signals a reference signal pattern index, and the terminal copies the reserved RE configuration from the corresponding reference signal pattern, significantly reducing signaling overhead while ensuring reliable data transmission
Solution Approach 2:
The patent changes the parameter representation from explicit reserved RE locations to implicit reference signal pattern indices. By signaling the pattern index rather than individual RE positions, the system achieves detailed reserved RE configuration with minimal signaling overhead, as the actual configuration details are derived from the referenced pattern
Data Source
AI summary
A resource configuration method, an apparatus, and a system are disclosed. The method includes: determining a reserved resource element (RE) in a resource unit, where the reserved RE is included in a reserved resource; and transmitting data on all or some REs other than the reserved resource. The resource unit includes X resource blocks (RBs) in frequency domain and includes Y symbols in time domain, where X and Y are positive integers. According to the resource configuration method provided in the present disclosure, a data conflict between different terminals during data transmission can be reduced, and resource utilization can be improved.
