Abstract

A discontinuous reception (DRX) parameter configuration method includes: receiving a wake-up parameter associated with a wake-up message configured by a base station for a terminal, wherein the wake-up message is configured to instruct the terminal to detect whether the wake-up message is received within each DRX cycle; in response to that the wake-up message is detected within a current DRX cycle, entering a continuous active period at an end of the current DRX cycle; and when the continuous active period ends, entering a target DRX cycle according to the wake-up parameter, wherein the target DRX cycle is a first DRX cycle or a second DRX cycle, and a duration of the first DRX cycle is longer than a duration of the second DRX cycle.

Claims (50)

1. A discontinuous reception (DRX) parameter configuration method, the method applied to a terminal and comprising:

receiving a wake-up parameter associated with a wake-up message configured by a base station for the terminal, wherein the wake-up message is configured to instruct the terminal to detect whether the wake-up message is received within each DRX cycle;

in response to determining that the wake-up message is received within a current DRX cycle, entering a continuous active period at an end of the current DRX cycle; and

when the continuous active period ends, entering a target DRX cycle according to the wake-up parameter, wherein the target DRX cycle is a first DRX cycle or a second DRX cycle, and a cycle duration of the first DRX cycle is longer than a cycle duration of the second DRX cycle;

wherein the wake-up parameter comprises a first wake-up parameter, the first wake-up parameter is configured to instruct the terminal to count a total number of wake-up messages received in a plurality of designated time units, and the designated time units comprise subframes and symbols.

2. The method of claim 1 , wherein:

the wake-up parameter further comprises a second wake-up parameter; and

the second wake-up parameter is configured to instruct the terminal to determine whether the total number of wake-up messages is lower than a predetermined threshold.

3. The method of claim 2 , wherein determining that the wake-up message is received within the current DRX cycle comprises:

in response to determining that the wake-up message is received at a target time unit within the current DRX cycle, determining that the wake-up message is received within the current DRX cycle, wherein the target time unit comprises a subframe and a symbol.

4. The method of claim 3 , wherein the target time unit is determined by:

receiving a target resource configured by the base station for the terminal through preset signaling; and

using a time unit corresponding to the target source as the target time unit, wherein the time unit comprises a subframe and a symbol.

5. The method of claim 3 , wherein the target time unit is determined by:

determining the target time unit according to a pre-configuration on the terminal.

6. The method of claim 2 , wherein when the continuous active period ends, entering the target DRX cycle according to the wake-up parameter comprises:

in response to determining that the total number of wake-up messages is lower than the threshold, when the continuous active period ends, entering the first DRX cycle; and

in response to determining that the total number of wake-up messages reaches or exceeds the threshold, when the continuous active period ends, entering the second DRX cycle.

7. The method of claim 2 , further comprising:

in response to entering the first DRX cycle when the continuous active period ends, recounting a total number of received wake-up messages in a plurality of time units at designated locations within a currently entered first DRX cycle according to the first wake-up parameter, wherein the time unit comprises a subframe and a symbol;

in response to determining that the total number of wake-up messages is lower than a reference threshold, when the first DRX cycle ends, entering a new first DRX cycle; and

in response to determining that the total number of wake-up messages reaches or exceeds the reference threshold, when the first DRX cycle ends, re-entering the continuous active period.

8. The method of claim 1 , further comprising:

in response to determining that the wake-up message is not received within the current DRX cycle, when the current DRX cycle ends, entering the first DRX cycle which remains a sleep state, wherein the sleep state is a state in which the terminal does not monitor a physical downlink control channel (PDCCH).

9. A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of a terminal, cause the terminal to perform the discontinuous reception (DRX) parameter configuration method according to claim 1 .

10. A discontinuous reception (DRX) parameter configuration method, the method applied to a base station and comprising:

configuring a wake-up parameter associated with a wake-up message for a terminal; and

sending the wake-up parameter to the terminal;

wherein the wake-up message is configured to instruct the terminal to detect whether the wake-up message is received within each DRX cycle, and in response to determining that the wake-up message is received within a current DRX cycle, enter a continuous active period for continuously receiving data at an end of the current DRX cycle; and

wherein the wake-up parameter is configured to instruct the terminal to enter a target DRX cycle when the continuous active period ends, the target DRX cycle is a first DRX cycle or a second DRX cycle, and a cycle duration of the first DRX cycle is longer than a cycle duration of the second DRX cycle; and

the wake-up parameter comprises a first wake-up parameter, the first wake-up parameter is configured to instruct the terminal to count a total number of wake-up messages received in a plurality of designated time units, and the designated time units comprise subframes and symbols.

11. The method of claim 10 , wherein:

the wake-up parameter further comprises a second wake-up parameter; and

the second wake-up parameter is configured to instruct the terminal to determine whether the total number of wake-up messages is lower than a predetermined threshold.

12. The method of claim 11 , further comprising:

configuring a target resource for the terminal, wherein the target resource is a resource corresponding to a target time unit, the target time unit is a time unit in which the terminal detects whether the wake-up message is received within each DRX cycle, and the time unit comprises a subframe and a symbol; and

sending the target resource to the terminal through preset signaling.

13. A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of a base station, cause the base station to perform the discontinuous reception (DRX) parameter configuration method according to claim 10 .

14. A base station, comprising:

a processor; and

a memory storing instructions executable by the processor;

wherein the processor is configured to perform the discontinuous reception (DRX) parameter configuration method according to claim 10 .

15. A terminal, comprising:

a processor; and

a memory storing instructions executable by the processor;

wherein the processor is configured to:

receive a wake-up parameter associated with a wake-up message configured by a base station for the terminal, wherein the wake-up message is configured to instruct the terminal to detect whether the wake-up message is received within each discontinuous reception (DRX) cycle;

in response to determining that the wake-up message is received within a current DRX cycle, enter a continuous active period at an end of the current DRX cycle; and

when the continuous active period ends, enter a target DRX cycle according to the wake-up parameter, wherein the target DRX cycle is a first DRX cycle or a second DRX cycle, and a cycle duration of the first DRX cycle is longer than a cycle duration of the second DRX cycle;

wherein the wake-up parameter comprises a first wake-up parameter, the first wake-up parameter is configured to instruct the terminal to count a total number of wake-up messages received in a plurality of designated time units, and the designated time units comprise subframes and symbols.
