Abstract: Embodiments of this application relate to a wake-up signal WUS detection method and apparatus, used to reduce signaling overheads of a network side device. The WUS detection method is as follows: A terminal device detects a terminal device-specific field in a detected WUS. If the terminal device detects the terminal device-specific field in the WUS, and detects that the WUS includes wake-up information for the terminal device, the terminal device determines, by using location information of the terminal device-specific field as a first index, a first physical uplink control channel PUCCH resource corresponding to the first index, and sends a first PUCCH, where the first PUCCH includes a first message used to feed back that the wake-up information for the terminal device is received.

Abstract: The present disclosure relates to terminal device wakeup methods and apparatus, network devices, and terminal devices. One example method includes receiving, by a first terminal device, configuration information of a first wakeup indication from a network device, where the first wakeup indication is used to indicate whether the first terminal device is to wake up, detecting, by the first terminal device, the first wakeup indication based on the configuration information, and in response to that the first wakeup indication is not detected, waking up, by the first terminal device, when the configuration information comprises first indication information. The first indication information is used to indicate the first terminal device to wake up when the first wakeup indication is not detected.

Abstract: An information sending method and an apparatus are provided. In the method, after sending a first message including uplink data to a network device, a terminal device receives first DCI from the network device, where the first DCI may include first indication information, and the first indication information is used to indicate that the network device has successfully demodulated the first message or used to indicate the terminal device to flush a HARQ buffer corresponding to the first message; and the terminal device may obtain the first indication information from the first DCI, and after obtaining the first indication information, the terminal device determines not to monitor a PDCCH search space within first duration after the first DCI. After sending the uplink data and receiving the first indication information from the network device, the terminal device may not monitor the PDCCH search space within specific duration.

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.

Abstract: Example reference signal sending methods and apparatus are described. In one example method, a terminal device detects whether a paging scheduling message exists in a PDCCH search space whose starting subframe is a subframe corresponding to a paging occasion (PO), and/or detects whether a wake-up signal (WUS) exists before a PO. A network device determines a time domain resource in first duration based on a quantity of paging occasions in a discontinuous reception period, where the time domain resource is a time domain resource in a time-frequency resource used to transmit a reference signal. The network device sends the reference signal to a terminal device on the time domain resource.
