## Abstract

In some implementations, a user equipment (UE) may transmit, to a network entity, a report associated with a UE capability for supporting a common timing advance (TA) configuration, wherein the report indicates one or more of: a supported TA type that includes one of an independent TA or a common TA; or a quantity of timing advance groups (TAGs) for a carrier aggregation. The UE may receive, from the network entity, a TA configuration based at least in part on the report.
