Abstract: A reference signal indication method and apparatus, a computer-readable storage medium, and a computer program are disclosed. In the method, a terminal device receives configuration information of a reference signal from a network device. The configuration information indicates at least one resource location of the reference signal. The terminal device further receives indication information of the reference signal from the network device. The indication information indicates whether the network device sends the reference signal at a first resource location. The at least one resource location includes the first resource location. According to the method, the terminal device can determine resource locations at which the network device sends the reference signal, to learn whether demodulation performance on a subsequent PO that needs to be monitored can be ensured by receiving the reference signal.

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: This application provides a system message transmission method, an apparatus, and a system. A first communications device configures a MIB message, and the MIB message may carry various different information used to transmit a SIB1, for example, any one or more of scheduling information, first information, and an operation mode of a carrier, so that a second communications device receives the SIB1 based on the MIB message. The first communications device may flexibly configure information used to transmit the SIB1. In addition, when configuring the MIB message, the first communications device may consider ensuring, through configuration or implicit indication, that resource locations for transmitting SIB1s of different cells in one period are different. This type of interference isolation mechanism can avoid mutual interference between transmission of SIB1s of different cells, so that transmission reliability of the SIB1s can be improved.
