Abstract: A resource determining method includes that a first terminal obtains transmission information from a second terminal, wherein the transmission information is used to indicate a first sidelink resource. The first terminal determines a second sidelink resource according to the transmission information, wherein a time range of the second sidelink resource does not overlap that of the first sidelink resource. The first terminal sends a first data to the second terminal on a sidelink resource of the second sidelink resource, wherein the first sidelink resource comprises a sidelink resource on which a second data is received by the second terminal.

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 this application provide a method for receiving and sending a reference signal, an apparatus, and a system, so that a network device can correctly demodulate uplink data of different terminal devices of a same cell. This solution is applicable to a wireless communications system including a first cell. The first cell includes a plurality of terminal devices that can transmit uplink data on a same time-frequency resource. A first terminal device in the plurality of terminal devices determines an index of a first sequence based on a first parameter value, and generates a first reference signal based on the first sequence indicated by the index of the first sequence. Then, the first terminal device sends the first reference signal to the network device. The first parameter value is different from a parameter value corresponding to another terminal device in the plurality of terminal devices.
