a time offset between a moment of entering the sleep state and a moment of waking up, configuration parameters of a PDCCH search space set associated with the sleep state, an index of a PDCCH search space set associated with the sleep state, or an identity of a PDCCH search space set associated with the sleep state.
6. The method according to claim 2 , further comprising 2 , selecting a different mode based on the sleep indication information;
wherein the mode comprises a first mode and a second mode,
wherein the first mode indicates entering the sleep state without waking up within on duration, and the second mode indicates entering the sleep state which needs to be awakened within On duration.
7. The method according to claim 6 , wherein for the second mode, scheduling information bit in downlink control information is used to indicate at least one of following:
a time offset between a moment of entering the sleep state and a moment of waking up, configuration parameters of the PDCCH search space set associated with the sleep state, an index of the PDCCH search space set associated with the sleep state, or an identity of the PDCCH search space set associated with the sleep state.
8. The method according to claim 4 , wherein said receiving sleep indication information from a base station comprises:
receiving downlink control information from the base station, wherein two bits in the downlink control information are used to indicate the sleep indication information, and the sleep indication information is transmitted in a PDCCH in a UE-specific search space.
9. The method according to claim 4 , wherein said receiving sleep indication information from a base station comprises:
receiving downlink control information from the base station, wherein one bit and a DCI format in the downlink control information are used to indicate the sleep indication information, and the sleep indication information is transmitted in a PDCCH in a LIE-specific search space.
10. The method according to claim 9 , wherein said entering the sleep state and selecting a different mode based on the sleep indication information comprises:
when one bit in the downlink control information indicates to enter the sleep state and the DCI format is a downlink DCI format, entering the sleep state and selecting the first mode; or
when one hit in the downlink control information indicates to enter the sleep state, and the DCI format is an uplink DCI format, entering the sleep state and selecting the second mode.
11. The method according to claim 4 , wherein said receiving sleep indication information from a base station comprises:
receiving downlink control information from the base station, wherein one bit and a frequency domain resource allocation field in the downlink control information are used to indicate the sleep indication information, and the sleep indication information is transmitted in a PDCCH in a UE-specific search space.
12. The method according to claim 11 , wherein said entering the sleep state and selecting a different mode based on the sleep indication information comprises:
when one bit in the downlink control information indicates to enter the sleep state, and the frequency domain resource allocation field is valid frequency domain resource allocation indication, entering the sleep state and selecting the first mode; or
when one bit in the downlink control information indicates to enter the sleep state, and the frequency domain resource allocation field is invalid frequency domain resource allocation indication, entering the sleep state and selecting the second mode.
13. The method according to claim 1 , further comprising selecting a different mode based on the sleep indication information;
wherein the mode comprises a first mode and a second mode,
wherein the first mode indicates entering the sleep state, and that a PDCCH in a search space set corresponding to a monitoring occasion that is separated by a preset monitoring duration from a current monitoring occasion has scheduling information, and the second mode indicates entering the sleep state, and that the PDCCH in the search space set corresponding to the monitoring occasion that is separated by the preset monitoring duration from the current monitoring occasion has no scheduling information.
14. The method according to claim 1 , further comprising selecting a different mode based on the sleep indication information;
wherein the mode comprises a first mode and a second mode,
wherein the first mode indicates entering the sleep state without waking up within on duration, and the second mode indicates entering the sleep state which needs to be awakened within On duration.
15. The method according to claim 13 , wherein for the first mode, scheduling information bit in the downlink control information is used to indicate at least one of following:
