Method for determining sleep state, terminal, and readable medium
View Patent ↗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.
1. A method for determining a sleep state, comprising:
receiving sleep indication information through a Physical Downlink Control Channel (PDCCH) from a base station; and
entering the sleep state and 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 the PDCCH has scheduling information, and the second mode indicates entering the sleep state, and that the PDCCH has no scheduling information.
2. The method according to claim 1 , further comprising:
based on the sleep indication information, not entering the sleep state.
3. The method according to claim 2 , wherein the sleep state comprises any one of following behaviors:
not monitoring the PDCCH within On duration, not monitoring one or more PDCCH search spaces or PDCCH search space sets that need to be monitored in a non-sleep state, or 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.
4. The method according to claim 1 , wherein for the second mode, scheduling information bit in Downlink Control Information (DCI) 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 1 , wherein 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 User Equipment (UE)-specific search space.
6. The method according to claim 1 , wherein 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 UE-specific search space.
7. The method according to claim 6 , wherein 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 bit 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.
8. The method according to claim 1 , wherein 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.
9. The method according to claim 8 , wherein 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.
10. A terminal, comprising:
a receiving circuitry configured to receive sleep indication information from a base station through a Physical Downlink Control Channel (PDCCH); and
a first processing circuitry configured to enter a sleep state and select 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 the PDCCH has scheduling information, and the second mode indicates entering the sleep state, and that the PDCCH has no scheduling information.
11. A nonvolatile or nontransitory computer readable storage medium having computer instructions stored therein, wherein when the computer instructions are executed, the method of claim 1 is performed.
12. A terminal comprising a memory and a processor, wherein the memory has computer instructions stored therein, and when the processor executes the computer instructions, the method of claim 1 is performed.
