Abstract

A method for determining a sleep state, a terminal, and a readable medium. The method for determining a sleep state comprises: receiving sleep instruction information sent by a base station; and on the basis of the sleep instruction information, entering a sleep state and selecting different modes. By application of the solution, a UE can be flexibly instructed to enter a sleep state without affecting the quality of service, thereby reducing the power consumption of the UE, and achieving the purpose of power saving.

3. The method according to claim 1 , further comprising: following entering the sleep state, selecting a different mode;

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.

4. The method according to claim 2 , wherein for the first mode, scheduling information bit in the 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 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.

5. The method according to claim 3 , wherein for the first mode, scheduling information bit in the downlink control information is used to indicate at least one of following:

8. A non-volatile or non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising computer instructions, which, when executed by a processor, cause the processor to:

receive sleep indication information from a base station; and

enter a sleep state or not enter the sleep state based on the sleep indication information;

wherein said receiving the sleep indication information from the base station comprises: receiving downlink control information from the base station, wherein at least one bit in the downlink control information is used to indicate the sleep indication information corresponding to a current User Equipment (UE);

wherein the sleep state comprises: changing from monitoring one or more PDCCH search spaces or PDCCH search space sets that need to be monitored in a non-sleep state to monitoring another one or more PDCCH search spaces or PDCCH search space sets.

9. The non-volatile or non-transitory computer readable storage medium according to claim 8 , wherein the processor is further caused to: following entering the sleep state, select a different mode;

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.

10. The non-volatile or non-transitory computer readable storage medium according to claim 8 , wherein the processor is further caused to: following entering the sleep state, select a different mode;

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.

11. The non-volatile or non-transitory computer readable storage medium according to claim 9 , wherein for the first mode, scheduling information bit in the 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 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.

12. The non-volatile or non-transitory computer readable storage medium according to claim 10 , wherein for the first mode, scheduling information bit in the 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 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.
