configuring downlink control information (DCI),
wherein the DCI carries power saving information of at least one user equipment (UE), the power saving information is used to indicate at least one power saving scheme,
wherein the power saving scheme includes at least one of the following:
a fifth power saving scheme of configuring to sleep a secondary serving cell;
a thirteenth power saving scheme of configuring channel state information, CSI; or
a sixteenth power saving scheme of configuring spatial-domain adaptive power adjustment;
wherein when the power saving scheme includes the fifth power saving scheme of configuring the dormant secondary serving cells, the power saving information includes at least one of a quantity of dormant secondary serving cells or an index of the dormant secondary serving cells;
when the power saving scheme includes the thirteenth power saving scheme of configuring channel state information (CSI) the power saving information includes at least one of a quantity of CSI request power saving information and an index of the CSI request power saving information, wherein the CSI request power saving information includes at least one of a CSI parameter set, a CSI resource set, or a mapping relation between the CSI parameter set and the CSI resource set;
when the power saving scheme includes the sixteenth power saving scheme of configuring spatial-domain adaptive power adjustment, the power saving information includes at least one of a quantity of antennas, a quantity of spatial layers, a quantity of codebooks, or binding relationships between the antennas.

2. The power saving indication method according to claim 1 , wherein the power saving scheme further includes at least one of the following:
a first power saving scheme of configuring to wake up and monitor physical layer downlink control channel (PDCCH);
a second power saving scheme of configuring to sleep and not monitor PDCCH; or an eighth power saving scheme of configuring discontinuous reception.

3. The power saving indication method according to claim 2 , wherein when the power saving scheme includes the first power saving scheme of configuring to wake up and monitor PDCCH, the power saving information includes information indicating to wake up and monitor PDCCH in a preset time period.

4. The power saving indication method according to claim 2 , wherein when the power saving scheme includes the second power saving scheme of configuring to sleep and not monitor PDCCH, the power saving information includes information indicating to sleep and not monitor PDCCH in a preset period of time.

5. The power saving indication method according to claim 2 , wherein
when the power saving scheme includes the eighth power saving scheme of configuring discontinuous reception, the power saving information includes at least one discontinuous reception configuration parameter or indication information indicating a mapping relation between at least two discontinuous reception configuration parameters.

6. A power saving indication method, comprising:
receiving DCI sent by a network side,
wherein the DCI carries power saving information of at least one UE, the power saving information is used to indicate at least one power saving scheme,
wherein the power saving scheme includes at least one of the following:
a fifth power saving scheme of configuring to sleep a secondary serving cell;
a thirteenth power saving scheme of configuring channel state information, CSI; or
a sixteenth power saving scheme of configuring spatial-domain adaptive power adjustment;
wherein when the power saving scheme includes the fifth power saving scheme of configuring the dormant secondary serving cells, the power saving information includes at least one of a quantity of dormant secondary serving cells or an index of the dormant secondary serving cells;
when the power saving scheme includes the thirteenth power saving scheme of configuring channel state information (CSI) the power saving information includes at least one of a quantity of CSI request power saving information and an index of the CSI request power saving information, wherein the CSI request power saving information includes at least one of a CSI parameter set, a CSI resource set, or a mapping relation between the CSI parameter set and the CSI resource set;
when the power saving scheme includes the sixteenth power saving scheme of configuring spatial-domain adaptive power adjustment, the power saving information includes at least one of a quantity of antennas, a quantity of spatial layers, a quantity of codebooks, or binding relationships between the antennas.

7. The power saving indication method according to claim 6 , comprising:
performing a power saving operation in accordance with the power saving information carried in the DCI.

8. The power saving indication method according to claim 7 , wherein performing a power saving operation in accordance with the power saving information carried in the DCI comprises:
descrambling the DCI with a predetermined radio network temporary identity (RNTI); and
performing the power saving operation in accordance with information obtained after descrambling.

9. The power saving indication method according to claim 8 , wherein the DCI includes DCI in one format or DCIs in at least two formats, power saving information carried in DCIs in different formats in the DCIs in at least two formats are different.

10. The power saving indication method according to claim 9 , wherein when the DCI includes DCIs in at least two formats, the descrambling the DCI with a predetermined radio network temporary identity comprises:
descrambling the DCIs in different formats in the DCIs in at least two formats using predetermined different RNTIs, respectively.

11. The power saving indication method according to claim 6 , wherein the DCI further includes a DCI format identifier for identifying a type of power saving scheme indicated by the power saving information.

12. The power saving indication method according to claim 6 ,
wherein the power saving scheme further includes at least one of the following:
a first power saving scheme of configuring to wake up and monitor physical layer downlink control channel (PDCCH);
a second power saving scheme of configuring to sleep and not monitor PDCCH; or an eighth power saving scheme of configuring discontinuous reception.

13. The power saving indication method according to claim 12 , wherein
when the power saving scheme includes the first power saving scheme of configuring to wake up and monitor PDCCH, the power saving information includes information indicating to wake up and monitor PDCCH in a preset time period.

14. The power saving indication method according to claim 2 , wherein
when the power saving scheme includes the second power saving scheme of configuring to sleep and not monitor PDCCH, the power saving information includes information indicating to sleep and not monitor PDCCH in a preset period of time.

15. The power saving indication method according to claim 12 , wherein
when the power saving scheme includes the eighth power saving scheme of configuring discontinuous reception, the power saving information includes at least one discontinuous reception configuration parameter or indication information indicating a mapping relation between at least two discontinuous reception configuration parameters.
