Implementation method, device, user equipment, and base station for discontinuous reception

1. A method for implementing discontinuous reception (DRX), applied to a User Equipment (UE), the method comprising:

when the UE is switched from a DRX off stage in an idle state to a DRX on stage, receiving listening indication information from a base station; and

in response to determining based on the listening indication information that it is not needed to continue listening for control information in the DRX on stage, controlling the UE to switch from the DRX on stage to the DRX off stage,

wherein said receiving the listening indication information from the base station comprises:

determining a position for transmitting the listening indication information in the DRX on stage based on a system protocol;

determining a window or a position for receiving the listening indication information based on the position for transmitting the listening indication information in the DRX on stage; and

receiving the listening indication information at the window or position for receiving the listening indication information;

or,

said receiving the listening indication information from the base station comprises:

receiving control signaling containing a position for transmitting the listening indication information in the DRX on stage;

determining a window or a position for receiving the listening indication information based on the position for transmitting the listening indication information in the DRX on stage; and

receiving the listening indication information at the window or the position for receiving the listening indication information.

2. The method of claim 1 , wherein the listening indication information is transmission direction indication information; or, the listening indication information is listening control signaling; or, the listening indication information is a wakeup signal.

3. The method of claim 2 , further comprising:

when the transmission direction indication information indicates that all transmission units in the DRX on stage are non-downlink transmission units, determining that it is not needed to continue listening for the control information in the DRX on stage; or

when the transmission direction indication information indicates that a downlink transmission unit exists in the DRX on stage, determining that it is needed to continue listening for the control information in the DRX on stage.

4. The method of claim 3 , further comprising:

in response to determining based on the transmission direction indication information that it is needed to listen for the control information in the DRX on stage, determining a downlink transmission unit needed to be listened in the DRX on stage; and

listening for the control information in the downlink transmission unit needed to be listened.

5. The method of claim 2 , further comprising:

when the listening control signaling indicates to listen for the control information, parsing, from the listening control signaling, the downlink transmission unit needed to be listened; and

listening for the control information in the downlink transmission unit.

6. The method of claim 2 , further comprising:

when the wakeup signal is a first sequence, determining that it is not needed to continue listening for the control information in the DRX on stage; or

when the wakeup signal is a second sequence, determining that it is needed to continue listening for the control information in the DRX on stage.

7. The method of claim 1 , further comprising:

in response to determining based on the listening indication information that it is needed to listen the control information in the DRX on stage, continuing listening for the control information in the DRX on stage.

8. A communication system implementing the method of claim 1 , comprising the UE and the base station, wherein the base station is configured to:

when the UE is switched from the DRX off stage in an idle state to the DRX on stage, determine, based on whether downlink control information or data is needed to be sent to the UE, listening indication information to be sent; and

send the listening indication information;

wherein the UE is controlled to switch from the DRX on stage to the DRX off stage to thereby avoid invalid detection of control information and reduce energy consumption in detection of the control information.

9. A device for implementing discontinuous reception (DRX), implemented by a User Equipment (UE), comprising:

a processor; and

memory configured to store an instruction executable by the processor,

wherein the processor is configured to;

when the UE is switched from a DRX off stage in an idle state to a DRX on stage, receive listening indication information from a base station; and

in response to determining based on the listening indication information that it is not needed to continue listening for control information in the DRX on stage, control the UE to switch from the DRX on stage to the DRX off stage,

wherein the processor is further configured to:

determine a position for transmitting the listening indication information in the DRX on stage based on a system protocol;

determine a window or a position for receiving the listening indication information based on the position for transmitting the listening indication information in the DRX on stage; and

receive the listening indication information at the window or position for receiving the listening indication information;

or,

the processor is further configured to:

receive control signaling containing a position for transmitting the listening indication information in the DRX on stage;

determine a window or a position for receiving the listening indication information based on the position for transmitting the listening indication information in the DRX on stage; and

receive the listening indication information at the window or the position for receiving the listening indication information.

10. The device of claim 9 , wherein the listening indication information is transmission direction indication information; or, the listening indication information is listening control signaling; or, the listening indication information is a wakeup signal.

11. The device of claim 10 , wherein the processor is further configured to:

when the transmission direction indication information indicates that all transmission units in the DRX on stage are non-downlink transmission units, determine that it is not needed to continue listening for the control information in the DRX on stage; and

when the transmission direction indication information indicates that a downlink transmission unit exists in the DRX on stage, determine that it is needed to continue listening for the control information in the DRX on stage.

12. The device of claim 11 , wherein the processor is further configured to:

in response to determining based on the transmission direction indication information that it is needed to listen for the control information in the DRX on stage, determine a downlink transmission unit needed to be listened in the DRX on stage; and

listen for the control information in the downlink transmission unit needed to be listened.

13. The device of claim 10 , wherein the processor is further configured to:

when the listening control signaling indicates to listen for the control information, parse, from the listening control signaling, the downlink transmission unit needed to be listened; and

listen for the control information in the downlink transmission unit.

14. The device of claim 10 , wherein the processor is further configured to:

when the wakeup signal is a first sequence, determine that it is not needed to continue listening for the control information in the DRX on stage; and

when the wakeup signal is a second sequence, determine that it is needed to continue listening for the control information in the DRX on stage.
