FDD Uplink Channel Reassignment for TDD Operations

The patent enables FDD uplink channels to serve dual purposes: traditional FDD operations and TDD operations. By allowing the same physical uplink channel to be dynamically allocated for both FDD and TDD functions, the system increases TDD resource availability without requiring additional dedicated TDD channels, thereby resolving the contradiction between maintaining FDD stability and expanding TDD capacity.

The system implements dynamic channel allocation where the availability and usage of FDD uplink channels for TDD operations is adjusted in real-time based on network conditions, user device requirements, and traffic demands. This dynamic flexibility allows the network to optimize resource distribution, reducing latency by allocating TDD resources when needed while maintaining overall network stability.

The patent transforms dedicated FDD uplink channels into multi-functional resources that can be dynamically assigned for both FDD and TDD operations. This increases resource utilization efficiency by ensuring that when FDD uplink channels are not actively used for their primary function, they can be repurposed for TDD operations, thereby reducing waste and improving overall spectrum efficiency.

The system implements self-service mechanisms where user devices and network elements automatically detect and utilize available FDD uplink channels for TDD operations without requiring complex manual configuration. The network autonomously manages the dynamic allocation and switching between FDD and TDD modes, reducing the operational complexity burden on network operators while maximizing resource efficiency.
