Abstract: This application provides a method for waking up a terminal, a terminal, and a network device. In technical solutions provided in this application, a network device determines, from a plurality of wake-up signals that can wake up a to-be-woken-up terminal and that need to be monitored by the to-be-woken-up terminal for one PO, a target wake-up signal of the to-be-woken-up terminal, and sends the target wake-up signal to the to-be-woken-up terminal. If the terminal detects, for the one PO, at least one wake-up signal of the plurality of wake-up signals that can wake up the terminal and that need to be monitored by the terminal, the terminal monitors a downlink control channel at the PO.

Abstract: Embodiments of the present invention provide a reference signal sending method, a reference signal receiving method, and an apparatus. A reference signal sending method includes: obtaining a reference signal sequence, where the reference signal sequence includes multiple bits and exclusive OR of every two bits separated by one bit in the multiple bits is 1; performing Gaussian Minimum Shift Keying GMSK modulation on the reference signal sequence; and sending a modulated reference signal sequence. In the embodiments of the present invention, a reference signal sequence is designed as a sequence in which exclusive OR of every two bits separated by one bit is 1, GMSK modulation is performed on the reference signal sequence, and the same reference signal sequence is used to perform channel estimation during GMSK demodulation. Compared with a case in which a pseudo random sequence is used as a pilot symbol, channel estimation accuracy is improved.
