Abstract
A first communication device (100) and respective methods performed for operating on least two carriers that are accessed by an LBT procedure. The methods performed by the first communication device (100) comprises e.g. performing (S1) synchronized LBT procedures, on the at least two carriers and accessing (S2) the carriers based on the result of the synchronized LBT procedures.

1-11. (canceled)
A method for operating a first communication device in a wireless communication system, the first communication device being configured to operate on at least two carriers that are accessed by a Listen-Before-Talk (LBT) procedure, the method comprising:
- performing synchronized LBT procedures on the at least two carriers;
- and
- accessing the at least two carriers based on a result of the synchronized LBT procedures.
A method for operating a first communication device in a wireless communication system, the first communication device being configured to operate on at least two carriers that are accessed by a Listen-Before-Talk (LBT) procedure, the method comprising:
- performing a first LBT procedure on one of the at least two carriers;
- performing a quick Clear Channel Assessment (CCA) on the rest of the at least two carriers based on a result of the first LBT procedure;
- and
- accessing the at least two carriers based on a result of the quick CCA and the result of the first LBT procedure.
A first communication device configured to operate on at least two carriers that are accessed by a Listen-Before-Talk (LBT) procedure, comprising:
- communication circuitry configured to send and receive signals on the at least two carriers;
- and
- processing circuitry operatively associated with the communication circuitry and configured to:
- perform synchronized LBT procedures on the at least two carriers;
- and
- access the at least two carriers based on a result of the synchronized LBT procedures.
A first communication device configured to operate on at least two carriers that are accessed by a Listen-Before-Talk (LBT) procedure, comprising:
- communication circuitry configured to send and receive signals on the at least two carriers;
- and
- processing circuitry operatively associated with the input and output circuitry and configured to:
- perform a first LBT procedure on one of the at least two carriers;
- perform a quick Clear Channel Assessment (CCA) on the rest of the at least two carriers based on a result of the first LBT procedure;
- and
- access the at least two carriers based on a result of the quick CCA and the result of the first LBT procedure.
