1. A method for power saving mode switching, applied to a terminal, comprising:
receiving, from a network device, configuration information for a power saving mode, wherein the configuration information comprises one or more parameters corresponding to the power saving mode comprising a first power saving mode and a second power saving mode, and the configuration information comprises a first field, the first field corresponds to at least two first parameters in the one or more parameters,
wherein different values of the first field correspond to different groups of values for the at least two first parameters;
the at least two first parameters comprise at least one of:
a time gap between a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH) scheduled by the PDCCH; and
a time gap between a PDCCH and a physical uplink shared channel (PUSCH) scheduled by the PDCCH;
the maximum number of downlink multiple-input multiple-output (MIMO) layers;
the number of transmit antennas or transmit channels;
the number of receive antennas or receive channels;
uplink component carriers that are activated simultaneously;
downlink component carriers that are activated simultaneously;
a time gap between a PDSCH and an acknowledgment (ACK) or a negative acknowledgment (NACK);
a delay for PDSCH processing;
a delay for PUSCH preparation; and
the maximum number of uplink MIMO layers;
switching the terminal from the first power saving mode to the second power saving mode by using the one or more parameters comprised in the configuration information, in a case that scheduled information carried in a target PDCCH is not received within predetermined time in an active bandwidth part (BWP).
