Wireless Resource Allocation via Adaptive Frequency Hopping

The patent applies dynamics by making the resource allocation scheme adaptive to user mobility conditions. The system dynamically switches between frequency selective scheduling (for low-speed users with stable channels) and frequency hopping (for high-speed users with rapidly changing channels). This dynamic adaptation allows the system to maintain resource allocation efficiency across different mobility scenarios, resolving the contradiction between optimization for stationary users and applicability to mobile users.

The patent merges two resource allocation schemes: frequency selective scheduling and frequency hopping. Instead of using either one alone, the system combines them by allowing frequency selective scheduling to operate within each frequency hop interval. This merging enables the system to benefit from both approaches: frequency hopping provides adaptability to mobile stations, while frequency selective scheduling maintains resource efficiency by allocating resources based on instantaneous channel conditions within each hop.

The patent implements periodic action through frequency hopping, where the system periodically switches between different frequency bands according to a hopping sequence. Within each hop interval, resources are stably allocated to maintain data transmission stability. However, the periodic switching between frequency bands allows the system to adapt to channel state changes over time, effectively resolving the contradiction between stability and adaptability.
