Abstract: A signal processing method, a device, and a system are provided, to reduce noise interference generated by a repeater. The method includes: A first device determines a first time domain resource position for transmitting a first signal, and sends first control signaling to a second device at or before a start position of the first time domain resource position. The second device receives the first control signaling, and enables a signal amplification function of the second device based on the first control signaling.

Abstract: A communication method, an apparatus, and a system for determining, by a first terminal device, a reference time domain position based on a preconfigured uplink time-frequency resource, where the reference time domain position is the same as a reference time domain position determined by another terminal device in a plurality of terminal devices, and the reference time domain position is used to initialize a first sequence; generating, by the first terminal device, a first reference signal based on the first sequence and a time interval, where the time interval is an interval between the reference time domain position and a start time domain position of transmission of the first reference signal; and sending, by the first terminal device, the first reference signal to a network device.

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.
