Title: METHODS SWITCHING FREQUENCIES OF PRIMARY AND SECONDARY CARRIERS FOR MULTI-CARRIER COMMUNICATIONS AND RELATED WIRELESS DEVICES AND NETWORK NODES
Abstract:
Methods may be provided to operate a wireless terminal (UE) in communication with a radio access network (RAN) supporting multi-carrier communications using primary and secondary carriers and using first and second frequencies. Preconfiguration information may be received (1201), wherein the preconfiguration information defines a parameter to be used by the primary carrier over the second frequency. First multi-carrier communications may be communicated (1215) with the RAN using the primary carrier over the first frequency and using the secondary carrier over the second frequency. An instruction may be received (1207) to switch the primary carrier to the second frequency based on the preconfiguration information and to switch the secondary carrier to the first frequency. Responsive to receiving the instruction, second multi-carrier communications may be communicated (1215) with the RAN using the primary carrier over the second frequency and using a secondary carrier over the first frequency based on the preconfiguration information.
