1. A power-saving state switching method, comprising:
configuring, by a base station, a first power consumption mode of a terminal at a first time point, and transmitting configuration information of the first power consumption mode to the terminal,
wherein two or more power consumption modes are supported by the terminal,
the two or more power consumption modes comprise a normal power consumption mode and a low power consumption mode, and the low power consumption mode comprises at least one power-saving mode, or at least one sleep mode, or both the at least one power-saving mode and the at least one sleep mode,
wherein power consumption of the terminal in the normal power consumption mode is greater than the power consumption of the terminal in the low power consumption mode, the power consumption of the terminal in the power-saving mode is greater than the power consumption of the terminal in the sleep mode, and the respective power consumptions of the terminal in different power-saving modes or sleep modes are different,
when the first power consumption mode is the normal power consumption mode or the power-saving mode, the configuring the first power consumption mode of the terminal comprises:
configuring, by the base station, the first power consumption mode of the terminal in accordance with configuration information of a reception antenna of the terminal; or
randomly selecting, by the base station, one power consumption mode from the normal power consumption mode and the power-saving modes as the first power consumption mode; or
configuring, by the base station, the first power consumption mode of the terminal in accordance with a configuration history of the power consumption mode of the terminal; or
configuring, by the base station, the first power consumption mode of the terminal in accordance with a service type of the terminal,
wherein the power-saving mode comprises at least one of: a first power-saving mode based on the reception of a Wake-Up Signal (WUS), a second power-saving mode where a bandwidth for downlink control channel detection, or the quantity of times of downlink control channel blind detection, or both the bandwidth for downlink control channel detection and the quantity of times of the downlink control channel blind detection are reduced, a third power-saving mode where the quantity of times of Radio Resource Management (RRM) measurement is reduced, a fourth power-saving mode where the quantity of reception antennae is reduced, and a fifth power-saving mode where a transmission bandwidth, or a reception bandwidth, or the transmission bandwidth and the reception bandwidth are adjusted.
