Claim:
1. A method for frequency hopping based coexistence in an unlicensed radio frequency (RF) band, the method comprising: by a wireless communication device: establishing a connection between the wireless communication device and an eNodeB of a wireless network using a primary component carrier of a primary cell in a licensed radio frequency band; obtaining a configuration for a secondary cell from the eNodeB, the secondary cell operating in the unlicensed radio frequency band, and the configuration for the secondary cell including a set of frequency channels and a frequency hopping pattern for communicating via a secondary component carrier of the secondary cell; transmitting to the eNodeB or receiving from the eNodeB via the secondary component carrier during a first hop of the frequency hopping pattern using a first frequency channel in the set of frequency channels; and transmitting to the eNodeB or receiving from the eNodeB via the secondary component carrier during a second hop of the frequency hopping pattern using a second frequency channel in the set of frequency channels, wherein each hop of the frequency hopping pattern spans a time period less than a time corresponding to a maximum count for a system frame number (SFN).
