US 12,615,594 B2 · Methods and apparatuses for handling DRX operation in a wireless network

Abstract

A method for handling a Discontinuous reception (DRX) operation by a user equipment (UE) in a wireless network is provided. The method includes detecting an event. The event includes at least one of a hybrid automatic repeat request (HARQ) feedback being disabled, a HARQ feedback not being configured, or an unsuccessful multicast transport block (TB) decoding. Further, the method includes performing an action based on the detected event. In an example, the action includes adding an additional timing duration to at least one preconfigured DRX timer value and staying awake by the UE while the preconfigured timer is running. The action includes staying awake by the UE in spite of a multicast DRX active time being over and continuing to monitor for potential HARQ retransmission.

Dependent claims

A method for handling a discontinuous reception (DRX) operation by a user equipment (UE) in a wireless network, the method comprising:

determining, by the UE, that decoding of a multicast transport block (TB) has been unsuccessful;
detecting, by the UE, an event comprising at least one of a hybrid automatic repeat request (HARQ) feedback being disabled or a HARQ feedback not being configured;
and
performing, by the UE, at least one action based on the detected event,
wherein the at least one action comprises adding an additional timing duration to a preconfigured value of a DRX timer, and staying awake while the DRX timer with a value of sum of the additional timing duration and the preconfigured value is running.

2 more elements

A user equipment (UE) for handling a discontinuous reception (DRX) operation in a wireless network, comprising:

memory storing instructions;
and
at least one processor coupled to the memory, wherein the instructions, when executed by the at least one processor, cause the UE to:
determine that decoding of a multicast transport block (TB) has been unsuccessful,
detect an event comprising at least one of a hybrid automatic repeat request (HARQ) feedback being disabled or the HARQ feedback not being configured, and
perform at least one action based on the detected event,
wherein the at least one action comprises adding an additional timing duration to a preconfigured value of a DRX timer, and staying awake while the DRX timer with a value of sum of the additional timing duration and the preconfigured value is running.
