Abstract
Methods, systems, and devices for wireless communications are described. Multiple reference signal occasions may occur during an inactive period of a discontinuous reception cycle configured for a wireless device. An amount of time the UE will be awake during the discontinuous reception cycle if the UE wakes up during a reference signal occasion of the multiple reference signal occasions may be determined for each of the reference signal occasions. The UE may wake up during the reference signal occasion associated with the shortest amount of awake time relative to the other reference signal occasions.
Claims30
A method for wireless communications at a user equipment (UE), comprising:
- identifying a first period for operating in an inactive state and a second period for operating in an active state;
- identifying a first reference signal occasion that occurs during the first period and is separated from the second period by a first duration and a second reference signal occasion that occurs during the first period and is separated from the second period by a second duration that is greater than the first duration;
- and
- transitioning to the active state during the second reference signal occasion based at least in part on the first duration being less than a threshold duration for the UE to transition from the inactive state to the active state and the second duration being greater than the threshold duration.
An apparatus for wireless communication at a user equipment (UE), comprising:
- a processor;
- memory coupled with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- identify a first period for operating in an inactive state and a second period for operating in an active state;
- identify a first reference signal occasion that occurs during the first period and is separated from the second period by a first duration and a second reference signal occasion that occurs during the first period and is separated from the second period by a second duration that is greater than the first duration;
- and
- transition to the active state during the second reference signal occasion based at least in part on the first duration being less than a threshold duration for the UE to transition from the inactive state to the active state and the second duration being greater than the threshold duration.
An apparatus for wireless communication at a user equipment (UE), comprising:
- means for identifying a first period for operating in an inactive state and a second period for operating in an active state;
- means for identifying a first reference signal occasion that occurs during the first period and is separated from the second period by a first duration and a second reference signal occasion that occurs during the first period and is separated from the second period by a second duration that is greater than the first duration;
- and
- means for transitioning to the active state during the second reference signal occasion based at least in part on the first duration being less than a threshold duration for the UE to transition from the inactive state to the active state and the second duration being greater than the threshold duration.
A non-transitory computer-readable medium storing code for wireless communication at a user equipment (UE), the code comprising instructions executable by a processor to:
- identify a first period for operating in an inactive state and a second period for operating in an active state;
- identify a first reference signal occasion that occurs during the first period and is separated from the second period by a first duration and a second reference signal occasion that occurs during the first period and is separated from the second period by a second duration that is greater than the first duration;
- and
- transition to the active state during the second reference signal occasion based at least in part on the first duration being less than a threshold duration for the UE to transition from the inactive state to the active state and the second duration being greater than the threshold duration.
