Abstract
A user equipment (UE) has a cellular connection established by a cellular chip, the cellular connection including a secondary component carrier (SCC) of carrier aggregation (CA) in the unlicensed spectrum. The UE receives, by a WiFi chip of the UE, a message from the cellular chip indicating a first frequency band corresponding to the SCC, determines whether a hotspot service is enabled utilizing at least a portion of the first frequency band that the cellular chip has indicated corresponds to the SCC and when the hotspot service is enabled, switches, by the WiFi chip, the hotspot service from the first frequency band to a second frequency band.
