The eNB 102 provides a connection request 204 requesting communication with the UE 300 on a first CC1 220a. Here, the first CC1 220a may correspond to a primary CC. In response to receiving the connection request 204 on the first CC1 220a, the UE 300 connects to the eNB 102 on the first CC1 220a to establish a connection with the eNB 102. Implementations herein are not limited to purely cellular wireless RATs, but may also apply to non-cellular wireless RATs in which CA techniques can be implemented. For example, any wireless network access point may be substituted for the eNB 102. Moreover, while examples herein are generally applied to LTE/LTE-Advanced RATs, implementations herein can be applied to other present or future-developed RATs supporting carrier aggregation.
