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: A slot resource configuration method in wireless communication and a device are provided, to resolve a problem of how to configure a flexible resource included in a new slot structure. In this method, user equipment-specific downlink control information (UE-specific DCI) sent by a base station is received, where the UE-specific DCI indicates a use configuration status of a flexible resource in at least one slot; and the flexible resource is configured according to the use configuration status. This method implements configuration of a flexible resource, so that the flexible resource can be used for communication, thereby improving slot resource usage.

Abstract: A reference signal transmission method is provided to reduce power consumption. The method may be applied to time-frequency tracking. The method includes a network device sends configuration information of a reference signal RS to a terminal device, where the configuration information is used to indicate at least one periodic target sending time period of the RS; and the network device sends the RS in a first target sending time period based on a first periodicity, where the first target sending time period belongs to the at least one periodic target sending time period. In this case, the RS is sent only in a part of the target sending time period, that is, the RS is not an always-on signal, and wake-up duration of UE is short. This helps UE reduce power consumption.
