Other embodiments may be described and claimed.

Beam switching in intra-band non-contiguous carrier aggregation

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.

The system, method, and apparatus can receive a configuration message having configuration information from an access node; determine a measurement period for a secondary cell (SCell) and a cell identification delay based upon the configuration information; identify a new detectable cell on a secondary component carrier (SCC) as the SCell within the cell identification delay; perform a measurement for a CA operation within the measurement period; and report the measurement to the access node. The configuration message can be a Radio Resource Control (RRC) message. The measurement for the CA operation can be a measurement of the SCell on the SCC. The system, method, and apparatus can multiply a measurement control parameter by a factor less than five (5) to determine the measurement period and can multiply a measurement control parameter by a factor less than twenty (20) to determine the cell identification delay. The system, method, and apparatus can further perform an action with respect to the SCell in response to the measurement.
