This disclosure provides techniques for activation of a secondary cell by a user equipment (UE) operating in a wireless network. For example, a UE receives a command to activate a secondary cell of the wireless network for wireless communication, and determines whether timing information is known by the UE for the secondary cell.

After which, the UE wirelessly communicate data over the wireless network using the secondary cell, based on the secondary cell being activated.
