Adaptive Guard Time Selection for Uplink Transmission

The patent applies parameter changes by dynamically adjusting the guard time parameter based on the timing advance value. The base station determines the timing advance for each unsynchronized device and configures the guard time accordingly, rather than using a fixed large guard time for all devices. This resolves the contradiction by making the guard time adaptive - large enough to ensure transmission reliability when needed, but small enough to minimize resource wastage when the timing advance value is small.

The patent changes the guard time parameter dynamically based on the timing advance value determined for each device. By setting the guard time proportional to or based on the timing advance value rather than using a fixed large value, the system reduces inter-symbol interference adequately while minimizing the impact on system capacity. This allows more efficient use of time resources and increases overall system throughput.

The patent implements self-service by having the base station automatically determine the timing advance value for each unsynchronized device and configure the appropriate guard time without manual intervention. The system self-adjusts to different cell sizes and device positions dynamically, eliminating the need for manual configuration while maintaining high adaptability. This resolves the contradiction by automating the parameter adjustment process.

The patent applies self-service by having the base station automatically measure the timing advance value and configure the guard time without manual operation. The system performs the measurement and configuration tasks autonomously, maintaining measurement precision through automated algorithms while dramatically improving ease of operation by eliminating manual configuration requirements. This resolves the contradiction by automating both measurement and configuration processes.
