Abstract

A method and apparatus for entering a sleep mode, a storage medium and a user equipment are provided. The method includes: monitoring a Physical Downlink Control Channel (PDCCH) and determining whether to enter a sleep mode, wherein entering the sleep mode includes skipping a duration of PDCCH monitoring occasions or modifying PDCCH configuration.

Claims (22)

1. A method for entering a sleep mode, comprising:

monitoring a Physical Downlink Control Channel (PDCCH) and determining whether to enter a sleep mode, wherein entering the sleep mode comprises skipping a duration of PDCCH monitoring occasions or modifying a configuration of the PDCCH;

wherein based on monitoring being completed on the PDCCH ending in frame n and it being determined to enter the sleep mode, any one of following actions is performed:

not monitoring the PDCCH on any frame from (n+1)th to (n+k−1)th frames, where ACK/NACK feedback indicated by the PDCCH starts at an (n+k)th frame; or

not monitoring the PDCCH on any frame from (n+1)th to (n+k−1)th frames, where a Physical Downlink Shared Channel (PDSCH) scheduled by the PDCCH ends at an (n+k)th frame;

wherein n and k are integers.

2. The method according to claim 1 , wherein prior to monitoring the PDCCH, the method further comprises:

determining whether to modify the configuration of the PDCCH after entering the sleep mode based on high-layer signaling from a base station.

3. The method according to claim 2 , wherein the high-layer signaling indicates whether to modify a PDCCH monitoring cycle, wherein a modified PDCCH monitoring cycle is longer than the PDCCH monitoring cycle before a UE enters the sleep mode.

4. The method according to claim 3 , wherein the high-layer signaling comprises a multiple of the PDCCH monitoring cycle before the UE enters the sleep mode.

5. A non-transitory 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:

monitor a Physical Downlink Control Channel (PDCCH) and determine whether to enter a sleep mode, wherein entering the sleep mode comprises skipping a duration of PDCCH monitoring occasions or modifying a configuration of the PDCCH;

wherein based on monitoring being completed on the PDCCH ending in frame n and it being determined to enter the sleep mode, the processor is further caused to perform any one of following actions:

not monitoring the PDCCH on any frame from (n+1)th to (n+k−1)th frames, where ACK/NACK feedback indicated by the PDCCH starts at an (n+k)th frame; or

not monitoring the PDCCH on any frame from (n+1)th to (n+k−1)th frames, where a Physical Downlink Shared Channel (PDSCH) scheduled by the PDCCH ends at an (n+k)th frame;

wherein n and k are integers.

6. A user equipment comprising a memory and a processor, wherein the memory stores one or more programs, the one or more programs comprising computer instructions, which, when executed by the processor, cause the processor to:

monitor a Physical Downlink Control Channel (PDCCH) and determining whether to enter a sleep mode, wherein entering the sleep mode comprises skipping a duration of PDCCH monitoring occasions or modifying a configuration of the PDCCH;

wherein based on monitoring being completed on the PDCCH ending in frame n and it being determined to enter the sleep mode, the processor is further caused to perform any one of following actions:

not monitoring the PDCCH on any frame from (n+1)th to (n+k−1)th frames, where ACK/NACK feedback indicated by the PDCCH starts at an (n+k)th frame; or

not monitoring the PDCCH on any frame from (n+1)th to (n+k−1)th frames, where a Physical Downlink Shared Channel (PDSCH) scheduled by the PDCCH ends at an (n+k)th frame;

wherein n and k are integers.
