Abstract

A discontinuous reception configuration method includes: starting or restarting a first timer; and suspending running of the first timer in a case that a time unit corresponding to the first timer does not meet a first condition.

First claim

What is claimed is:

1 . A discontinuous reception (DRX) configuration method, performed by a terminal device, the method comprising:
starting or restarting a first timer; and suspending running of the first timer in a case that a time unit corresponding to the first timer does not meet a first condition; wherein the first condition comprises at least one of following that: the time unit is a downlink time unit, wherein the downlink time unit comprises at least one of the following: a semi-static downlink time unit or a downlink time unit indicated by indication signaling in a subframe format; the time unit is a flexible time unit; there is a physical downlink control channel (PDCCH) monitoring occasion in the time unit; or there is a PDCCH monitoring occasion of a first search space or a first search space group in the time unit; wherein the method further comprises: determining a target start time of the first timer according to a start time offset rule; wherein the start time offset rule is related to a first time range, and the first time range is related to an initial start time of the first timer;
wherein the determining the target start time of the first timer according to the start time offset rule comprises:
in a case that a second time unit in which the initial start time is located meets the first condition and/or a second condition, determining the initial start time as the target start time; and
in a case that the second time unit in which the initial start time is located does not meet the first condition and/or the second condition, determining a start time of a third time unit as the target start time;
wherein the third time unit is the time unit that meets the first condition and/or the second condition within the first time range and is closest to the initial start time;
wherein the second condition is:
in the first timer started at the target start time, a ratio of a number of time units meeting the first condition to a total number of time units corresponding to the first timer is greater than or equal to a second ratio, and the second ratio is greater than 0 and less than 1.

2 . The method according to claim 1 , wherein the suspending running of the first timer in a case that the time unit corresponding to the first timer does not meet the first condition comprises:
in a case that a first time unit in which a start time or a restart time of the first timer is located does not meet the first condition, suspending running of the first timer; or in a case that an i-th time unit after the first time unit does not meet the first condition, suspending running of the first timer until an (i+m)-th time unit meets the first condition, wherein i and m are integers greater than or equal to 1.

3 . The method according to claim 1 , further comprising:
in a case that the time unit corresponding to the first timer meets the first condition, continuing to run the first timer.

4 . The method according to claim 3 , wherein the continuing to run the first timer in a case that the time unit corresponding to the first timer meets the first condition comprises:
in a case that a first time unit in which a start time or a restart time of the first timer is located meets the first condition, continuing to run the first timer; and/or in a case that an i-th time unit after the first time unit meets the first condition, continuing to run the first timer until an (i+n)-th time unit does not meet the first condition, or until the first timer expires, wherein i and n are integers greater than or equal to 1.

5 . The method according to claim 1 , wherein a duration for which the first timer is suspended is one of following: an active time, a DRX active time, and an inactive time.

6 . The method according to claim 1 , wherein the first condition further comprises at least one of following that:
the time unit is an uplink time unit; there is no synchronization signal and PBCH block (SSB) in the time unit; there is an SSB in the time unit; the time unit is a special time unit, a ratio of a number of downlink symbols in the special time unit to a total number of symbols in the special time unit is greater than a first ratio, and the first ratio is greater than 0 and less than 1; there is no PDCCH monitoring occasion in the time unit; there is no PDCCH monitoring occasion of the first search space or the first search space group in the time unit; first downlink control information (DCI) is not received within the time unit; the first DCI is received within the time unit; a bandwidth part (BWP) activated in the time unit is a first BWP, and the first BWP is one of the following: a non-dormant BWP, a dormant BWP, a first activated BWP, and a default BWP; the time unit is not a target time unit, and the target time unit corresponds to at least one of: a BWP switching delay, an interruption time caused by BWP switching, or a first application delay; or the time unit is the target time unit.

7 . The method according to claim 1 , wherein at least one of following is stipulated by the protocol or configured by the network-side device:
the first time range; wherein the first time range comprises N slots or subframes, and N is an integer greater than or equal to 0; or a default time range.

8 . The method according to claim 1 , wherein the method further comprises:
receiving second downlink control information (DCI), wherein the second DCI carries indication information of the start time offset rule.

9 . The method according to claim 1 , wherein before the determining a target start time of the first timer according to a start time offset rule, the method further comprises:
reporting a reference value of the first time range to the network-side device, wherein the reference value of the first time range is used to determine the first time range.

10 . A network-side device, comprising: a memory, a processor, and programs or instructions stored in the memory and executable on the processor, wherein the programs or instructions, when executed by the processor, cause the network-side device to perform:
configuring a first timer; and sending configuration information, wherein the configuration information is used to instruct the terminal device to suspend running of the first timer in a case that a time unit corresponding to the first timer meets a first condition after the first timer is started or restarted; wherein the first condition comprises at least one of following that: the time unit is a downlink time unit, wherein the downlink time unit comprises at least one of the following: a semi-static downlink time unit or a downlink time unit indicated by indication signaling in a subframe format; the time unit is a flexible time unit; there is a physical downlink control channel (PDCCH) monitoring occasion in the time unit; or there is a PDCCH monitoring occasion of a first search space or a first search space group in the time unit; wherein the method further comprises: configuring a start time offset rule, wherein the start time offset rule is used to determine a target start time of the first timer, the start time offset rule is related to a first time range, and the first time range is related to an initial start time of the first timer; wherein in a case that a second time unit in which the initial start time is located meets the first condition and/or a second condition, the target start time is the initial start time; and in a case that the second time unit in which the initial start time is located does not meet the first condition and/or the second condition, the target start time is a start time of a third time unit; wherein the third time unit is
