Background In the fifth generation mobile communication system and its evolution system, various waveform enhancement processing techniques, such as frequency domain spectral shaping, have been introduced in the industry to optimize uplink performance (e.g., reduce peak-to-average ratio, improve coverage). The capabilities of terminal devices are becoming more and more diverse, and different terminals may support different processing parameters, algorithms and configuration modes. However, existing communication standards lack a specially designed, standardized information element for efficiently, flexibly, and extendably carrying the processing power supported by the terminal.
