SECONDARY CELL (SCELL) ACTIVATION IN A WIRELESS NETWORK FOR A HIGH SPEED SCENARIO

Abstract:

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. Based on the determination, the UE performs a first secondary cell activation within first time period based on the timing information being known, or performs a second secondary cell activation within a second time period based on the timing information being unknown. After which, the UE wirelessly communicate data over the wireless network using the secondary cell, based on the secondary cell being activated.
