Radio Resource Allocation Pattern Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio telecommunication systems, the existing methods for allocating radio resources result in an increased amount of control information, leading to reduced downlink throughput and potential transmission delays, especially in scenarios requiring real-time services like VoIP, due to the complexity of reporting resource allocation results.
Innovation Solution
A radio resource allocation method that selects and notifies a resource allocation pattern from pre-defined patterns, using pattern identifier information and startup position information within a resource management space, specifically for frequency, time, and code resources, to minimize control information and ensure timely transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed resource allocation information is reported to notify the allocated resource, then the resource allocation accuracy is improved, but the amount of control information increases
Solution Approach 1:
The patent segments the resource allocation notification into two parts: (1) a compact pattern identifier that references a pre-defined resource allocation pattern, and (2) optional offset information for fine-tuning the allocation. This segmentation allows the system to maintain resource allocation accuracy while significantly reducing the amount of control information that needs to be transmitted, as the bulk of the allocation details are implicitly defined by the pattern rather than explicitly transmitted.
Solution Approach 2:
The patent employs preliminary action by pre-defining multiple resource allocation patterns before actual resource allocation occurs. These patterns are stored in both the base station and mobile terminal, allowing the system to reference pre-prepared allocation schemes rather than transmitting complete allocation details during operation. This preliminary preparation enables efficient resource allocation with minimal control information exchange.
2Loss of information
If the amount of control information is increased to report resource allocation results, then the resource allocation completeness is improved, but the downlink throughput decreases
Solution Approach 1:
The notification message is segmented into a compact pattern identifier field and optional offset fields, separating the essential allocation information from detailed resource specifications. This segmentation ensures that resource allocation completeness is maintained through the pattern reference while minimizing the control information overhead that would otherwise reduce downlink throughput.
Solution Approach 2:
Instead of transmitting complete resource allocation details, the system transmits a compact pattern identifier that copies or references a pre-defined allocation pattern stored at both the base station and mobile terminal. This copying approach ensures that the complete allocation information is available at the receiver without requiring its full transmission, thereby preserving downlink throughput while maintaining allocation completeness.
3Measurement precision
If complex spatial range information is reported to indicate allocated resources, then the resource allocation precision is improved, but the notification information volume increases
Solution Approach 1:
The patent segments the spatial range information representation by using a pattern identifier to reference pre-defined spatial patterns rather than transmitting complete spatial coordinate information. This segmentation maintains allocation precision through the pattern reference while dramatically reducing the notification information volume that would be required to describe complex spatial ranges in detail.
Solution Approach 2:
Complex spatial allocation patterns are pre-calculated and stored in both the base station and mobile terminal before actual resource allocation. This preliminary action allows the system to reference pre-prepared spatial patterns using compact identifiers, ensuring allocation precision is maintained while minimizing the information volume required for notification during operation.
