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.

Abstract: Embodiments of the present invention provide a resource scheduling method. In the method, a terminal device receives a downlink control information (DCI) indication sent by a network device, wherein the DCI is used to indicate a first resource, and the first resource is a time-frequency resource for narrowband physical uplink shared channel (NPUSCH) format 2 transmission, wherein the NPUSCH format 2 is used to bear downlink hybrid automatic repeat request-acknowledgment (HARQ-ACK) feedback information, determines the first resource according to the DCI, and sends a scheduling request to the network device on the first resource

Abstract: A synchronization method includes generating, by a first device, a synchronization by way of orthogonal frequency division multiplexing (OFDM). The synchronization signal includes one or more of a first signal or a second signal. The first signal is used to determine a time domain start position occupied by data sent by the first device to a second device. The second signal is used to determine a frequency at which the second device sends data to the first device. The synchronization method also includes sending, by the first device, the synchronization signal to the second device.

Abstract: A communication method and system, and a related apparatus. The communication method is applied to the communication system including a first device and a second device. In the communication method, the first device may indicate the second device to reserve a channel resource, and the second device does not perform data transmission on the reserved channel resource. This prevents the second device from occupying channel resources for long time, to release channel resources for a cellular communication system. The first device may schedule a terminal device other than the second device by using the released channel resources. This improves data transmission efficiency.
