Method and apparatus for frequency hopping coexistence in unlicensed radio frequency bands for mobile devices
First 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).

Abstract
Apparatus and methods for frequency hopping among a set of frequency channels used for secondary cells by wireless devices operating with carrier aggregation across a combination of licensed and unlicensed radio frequency (RF) bands are described. A wireless device establishes a connection with an eNodeB using a primary component carrier (PCC) of a primary cell in a licensed radio frequency band. The wireless device obtains a configuration for a secondary cell operating in the unlicensed radio frequency band from the eNodeB, the configuration including a set of RF channels and a frequency-hopping pattern for communicating via a secondary component carrier in the secondary cell. The wireless device transmits to or receives from the eNodeB, via the SCC during a first hop of the frequency-hopping pattern using a first frequency channel in the set of frequency channels, and using a second frequency channel during a second hop.
