Title:
WAKE-UP SIGNAL PROCESSING METHOD AND APPARATUS, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/032772
Kind Code:
A1
Abstract:
The present application provides a wake-up signal processing method and apparatus, and a device. The method comprises: a network device modulating a first wake-up signal by means of a low-rate modulation mode to obtain a low-rate wake-up signal; superposing the low-rate wake-up signal with an OFDM signal to obtain a superposed signal; and sending the superposed signal to a terminal device. In this way, because the rate difference between the low-rate wake-up signal and the OFDM signal is large, the terminal device can demodulate the superposed signal by means of a demodulation mode with low power consumption, thereby reducing power consumption of the terminal device. In addition, due to low power consumption, the terminal device can more frequently detect the wake-up signal, so that the wake-up signal can be received in real time, thereby realizing quick wake-up of the terminal device, and satisfying the requirements of delay-sensitive services.
