Abstract
Methods and devices are provided whereby the primary uplink (and downlink carrier) can be dynamically changed. Embodiments are described wherein it is determine which carrier that is to be used as a new primary carrier instead of an old carrier currently being used as a primary carrier based on a criteria/trigger event. The new carrier can be signaled between the radio base station and the user equipment when switching to the new primary carrier.
Claims23
A method in a radio base station configured to transmit and/or receive data on multiple carriers to communicate with a user equipment, the multiple carriers comprising a primary carrier, the radio base station controlling which of the multiple carriers is the primary carrier, the method comprising the steps of:
- determining which carrier is to be used as a new primary carrier instead of an old carrier currently being used as a primary carrier based on a criteria/trigger event;
- signaling the new primary carrier to the user equipment;
- and
- switching to the new primary carrier to transmit and/or receive data communications with the user equipment.
A method in a user equipment configured to transmit and/or receive data on multiple carriers froth to communicate with a radio base station, the multiple carriers comprising a primary carrier, the method comprising the steps of:
- determining which carrier that is to be used as a new primary carrier instead of an old carrier currently being used as a primary carrier based on a criteria/trigger event;
- and
- signaling the new primary carrier to the radio base station.
-12. (canceled)
A radio base station configured to transmit to and or and/or receive data on multiple carriers to communicate with a user equipment, the multiple carriers comprising a primary carrier, the radio base station being arranged to control which of the multiple carriers that is the primary carrier, the radio base station comprising:
- a controller arranged to determine which carrier is to be used as a new primary carrier instead of an old carrier currently being used as a primary carrier based on a criteria/trigger event, and to signal the new primary carrier to the user equipment, wherein the controller is further arranged to switch to the new primary carrier to transmit and/or receive data communications with the user equipment.
-19. (canceled)
A user equipment configured to transmit to and or and/or receive data on multiple carriers to communicate with a radio base station, the multiple carriers comprising a primary carrier, the user equipment comprising:
- a controller arranged to determine which carrier is to be used as a new primary carrier instead of an old carrier currently being used as a primary carrier based on a criteria/trigger event, and to signal the new primary carrier to the radio base station.
