Abstract

A method for wireless communication by a UE includes receiving, from a network node, a first message indicating at least a first discontinuous reception (DRX) configuration associated with a DRX cycle at the network node. The DRX cycle may be enabled or disabled in accordance with whether the first DRX configuration is in an activated state. The method also includes receiving, from the network node, a second message indicating a group of uplink (UL) transmission configurations including at least a first UL configuration associated with the activated state of the first DRX configuration and a second UL configuration associated with the deactivated state of the first DRX configuration. The method further includes transmitting, to the network node, a third message in accordance with the first UL configuration in accordance with first DRX configuration being activated or the second UL configuration in accordance with first DRX configuration being deactivated.
