Relative Addressing for Resource Allocation in Frequency Overlay Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In broadband wireless communication systems, the frequency overlay scheme leads to increased overhead in resource allocation information due to the need for multiple MAP messages when terminals use multiple Frequency Assignments (FAs), complicating the process for both base stations and terminals.
Innovation Solution
The implementation of an addressing scheme that allocates relative addresses to Resource Blocks (RBs) based on the number of FAs used, allowing for the generation and transmission of resource allocation information through a primary FA, enabling efficient resource indication and allocation regardless of the number of FAs employed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple MAP messages are generated for each FA in the frequency overlay scheme, then resource allocation information can be delivered to terminals using multiple FAs, but the overhead in MAP messages increases proportionally to the number of FAs
Solution Approach 1:
The patent combines multiple FA-specific resource allocation information into a single unified MAP message. The base station generates one MAP message that includes resource allocation information for multiple FAs by allocating relative addresses to Resource Blocks across all FAs, thereby merging what would otherwise be multiple separate MAP messages into one, reducing overhead while maintaining complete resource allocation information delivery.
Solution Approach 2:
The patent creates a universal resource allocation mechanism that works for terminals using any number of FAs. By introducing relative address allocation that is independent of the specific FA configuration, the system achieves multi-functionality where a single MAP message structure can serve all terminal types (single FA, multiple FAs, different bandwidth configurations) without requiring separate specialized messages for each case.
2Ease of manufacture
If independent frame structure is adopted for each FA, then resource allocation can be carried out independently in each FA, but the complexity of checking multiple MAP messages increases for terminals using multiple FAs
Solution Approach 1:
The patent merges the resource allocation processing into a single unified process by using relative address allocation across all FAs. Instead of terminals independently processing multiple separate MAP messages, the terminal receives one MAP message containing relative addresses for Resource Blocks in all FAs, and the terminal's complexity is reduced because it only needs to check a single message rather than multiple independent ones.
Solution Approach 2:
The patent introduces relative addresses as an intermediary mechanism between the base station's resource allocation and the terminal's resource indication. This relative address system acts as a mediator that translates the multi-FA resource allocation into a unified format that terminals can process more easily, reducing the complexity of checking multiple MAP messages while maintaining the ability to allocate resources independently across FAs.
3Adaptability or versatility
If relative address allocation is implemented across all FAs, then a unified resource indication system is achieved, but the addressing scheme must adapt to different numbers of FAs
Solution Approach 1:
The patent creates a universal addressing scheme that adapts to different numbers of FAs automatically. The relative address allocation method is designed to work regardless of whether a terminal uses one FA, two FAs, or more FAs. The system maintains versatility by allowing the same basic addressing mechanism to serve all FA configurations, eliminating the need for separate specialized addressing schemes for different scenarios.
Solution Approach 2:
The patent introduces dynamic adaptability in the addressing scheme where the allocation of relative addresses automatically adjusts based on the actual number of FAs being used. The system dynamically adapts the relative address mapping to accommodate different FA configurations without requiring manual reconfiguration or complex re-synchronization, making the addressing scheme flexible and adaptable to varying network conditions.

AI summary
A broadband wireless communication system supporting a frequency overlay scheme is provided. An operating method of a base station includes allocating relative addresses to Resource Blocks in at least one operating Frequency Assignment (FA) of a terminal according to an addressing scheme for the terminal; generating at least one resource indicator represented with the relative addresses; generating resource allocation information which comprises the at least one resource indicator; and transmitting the resource allocation information through a primary FA of the terminal.
