    Abstract: This application provides a reference signal receiving method, a reference signal sending method, and an apparatus. The reference signal receiving method includes: when a terminal device is out of a first time period, detecting, by the terminal device, a first signal, and determining, based on a detection result of the first signal, whether to use a first reference signal to perform time-frequency tracking and/or channel measurement; and receiving, by the terminal device, a second reference signal when the terminal device is in the first time period, where the first reference signal and the second reference signal are reference signals used for time-frequency tracking and/or channel measurement.

    Abstract: Embodiments of this application provide a control channel configuration method, a base station, and a terminal device. The method includes: determining, by a base station, a configuration of a time-frequency resource unit from at least two configurations of a time-frequency resource unit of a control channel; and sending, by the base station, indication information to a terminal device, where the indication information is used to indicate the configuration of the time-frequency resource unit, and the at least two configurations of a time-frequency resource unit include a first configuration and a second configuration. In the embodiments of this application, the base station can flexibly configure the time-frequency resource unit of the control channel. In addition, flexibly configuring a time-frequency resource unit can reduce a probability that time-frequency resource units of different structures are blocked, thereby reducing complexity of detecting the control channel by the terminal device.

    Abstract: Various embodiments provide a method for receiving reference signal and a method for sending a reference signal. In those embodiments, a terminal device can determine a location of a resource element to which a reference signal is mapped. The terminal device can determine a reference signal sequence corresponding to the resource element. The index of each element in the reference signal sequence is determined based on a resource block index of a resource block corresponding to the resource element, a quantity of resource elements that carry the reference signal in the resource block, a resource block offset, or an inter-symbol offset. The terminal device can receive the reference signal by using the resource element, and performing channel estimation or channel sounding based on the received reference signal and the reference signal sequence. Therefore, the terminal device can complete channel estimation without learning of a system bandwidth.

    Abstract: In the method of present application, a terminal device obtains resource indication information. The resource indication information is used to indicate frequency domain resources in a control resource set. The resource indication information comprises S bits, where S is a positive integer. The terminal device determines the frequency domain resources in the control resource set based on the resource indication information, thereby improving communication efficiency of a network system.

    Abstract: A downlink control channel monitoring method includes determining a first search space (SS) set and a second SS set. The method also includes determining, based on a first priority of the first SS set and a second priority of the second SS set, whether to monitor a first physical downlink control channel (PDCCH) on a first downlink control channel candidate resource of the first SS set, and whether to monitor a second PDCCH on a second downlink control channel candidate resource of the second SS set. The first priority of the first SS set is equal to the second priority of the second SS set. The second PDCCH carries a power saving signal.
