Adaptive Feedback Channel Allocation in Mobile Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication systems, such as IEEE 802.16, inefficiently use radio resources for feedback channels due to fixed transmission rates and powers, and require multiple channels for large feedback information, limiting adaptability to channel environments and feedback types.
Innovation Solution
The method involves classifying feedback information into classes based on transmission periods and tile allocation, multiplexing payloads according to these classifications, and applying channel codes and orthogonal modulation to efficiently transmit feedback information, allowing for adaptive resource allocation and different transmission powers for varying feedback types.

1Productivity
If the same radio resource and the same data transmission rate are used for all feedback channels, then the system configuration is simple, but the radio resource cannot be efficiently used according to channel environments and feedback types
Solution Approach 1:
The patent applies dynamics by making the feedback channel allocation adaptive rather than fixed. The base station dynamically determines the number of feedback channels and their allocation based on real-time channel environment assessment and feedback type requirements. This allows the system to optimize radio resource usage by allocating more channels when more feedback information is needed and fewer channels when less feedback is required, directly resolving the contradiction between resource efficiency and system complexity.
Solution Approach 2:
The patent changes the parameter of feedback channel allocation from a fixed configuration to a variable one. The number of feedback channels is determined based on the amount of feedback information required, which varies according to channel conditions and feedback types. This parameter change enables the system to adjust the allocation dynamically, improving radio resource efficiency while managing complexity through structured determination criteria.
2Productivity
If a periodic feedback channel is allocated for use in feedback information from which intermittent feedback is required, then the feedback transmission is simplified, but the radio resource cannot be efficiently used for intermittent feedback
Solution Approach 1:
The patent applies dynamics by enabling the feedback channel allocation to adapt to the actual feedback transmission requirements. Instead of forcing intermittent feedback into a periodic channel structure, the system dynamically determines the number of feedback channels based on the specific feedback information needed. This allows intermittent feedback to be transmitted efficiently without requiring a dedicated periodic channel, resolving the contradiction between resource efficiency and transmission simplicity.
Solution Approach 2:
The patent changes the parameter of feedback channel allocation from a fixed periodic structure to a variable allocation that matches actual transmission needs. The number of feedback channels is determined based on the feedback information requirements, which may vary between periodic and intermittent patterns. This parameter change allows the system to optimize resource usage by allocating channels only when and where needed, rather than maintaining a constant periodic allocation.
3Quantity of substance
If multiple feedback channels are allocated to transmit large amounts of feedback information, then the feedback transmission capacity is sufficient, but the radio resource cannot be efficiently used
Solution Approach 1:
The patent applies dynamics by making the feedback channel allocation adaptive to the actual feedback information requirements. The base station determines the number of feedback channels based on real-time assessment of channel environments and feedback type needs. This dynamic allocation ensures that sufficient channels are provided when large amounts of feedback information must be transmitted, while avoiding the waste of allocating multiple channels when less feedback is required, thus resolving the contradiction between transmission capacity and resource efficiency.
Solution Approach 2:
The patent changes the parameter of feedback channel allocation from a fixed large allocation to a variable allocation that matches actual needs. The number of feedback channels is determined based on the amount of feedback information required, which varies according to channel conditions and feedback types. This parameter change allows the system to provide sufficient capacity when needed while optimizing resource usage by reducing the number of channels when less feedback is required.
