Uplink timing and frequency adjustment based on energy saving modes

Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, while operating in a second communication mode associated with a threshold for the first timing metric, a message to a network entity via first resources. Further, for the first resources, a first timing metric of the UE may fail to satisfy a threshold for operations via a first communication mode. The UE may then transmit, to the network entity, another message via second resources, where a type of message of the message is based on whether a second timing metric of the UE satisfies the threshold for the operations via the first communication mode for the second resources. Further, the network entity may switch communication modes and transmit a control message to the UE indication the switch. Moreover, the UE may further request for addition downlink reference signals which the network entity may transmit accordingly.
