A wireless communication network aggregates wireless network control signaling through a hub User Equipment (UE) using Carrier Aggregation (CA). The wireless access node selects the hub UE and directs the hub UE to aggregate the wireless network control signaling for other UEs by using CA traffic channels with the wireless access node. The hub UE exchanges the wireless network control signaling with the other UEs over wireless links. The hub UE aggregates the wireless network control signaling. The hub UE and the wireless access node exchange the aggregated wireless network control signaling over the CA traffic channels.
