Abstract:
1. A wireless access node of a wireless access network configured to perform a carrier aggregation (CA) communication mode between the wireless access node and a User Equipment device (UE), comprising: a communication interface configured to allocate one or more traffic channels and a signaling channel between the wireless access node and the UE; and a processing system coupled to the communication interface and configured to: determine a UE location of the UE in preparation for switching to the CA communication mode, wherein the UE location comprises a UE distance to the UE, a UE direction angle to the UE, and a UE elevation angle to the UE; determine if the UE is in-building using the UE location and setting a UE in-building state based on the UE location: if the UE in-building state is true and if a band availability information indicates that building-penetrating frequencies are available, then allocate a plurality of CA traffic channels to the UE from a building-penetrating frequency band; and if the UE in-building state is false or if the band availability information indicates that the building-penetrating frequencies are unavailable, then allocate the plurality of CA traffic channels from a non-penetrating frequency band.
