Abstract
A user equipment, method used in a user equipment, and an apparatus for a user equipment include receiving from a first cell operated in a licensed band, configuration information configuring a second cell operated in an unlicensed band, performing a listen-before-talk (LBT) procedure on the second cell, counting a number of failures of the LBT procedure on the second cell, and transmitting information based on the number of failures of the LBT procedure on the second cell, to the first cell operated in the licensed band, the information indicating the failure of the LBT procedure on the second cell.
Claims3
A user equipment comprising:
- a processor and a memory coupled to the processor, the processor configured to
- receive from a first cell operated in a licensed band, configuration information configuring a second cell operated in an unlicensed band,
- perform a listen-before-talk (LBT) procedure on the second cell,
- count a number of failures of the LBT procedure on the second cell, and
- transmit information based on the number of failures of the LBT procedure on the second cell, to the first cell operated in the licensed band, the information indicating the failure of the LBT procedure on the second cell.
An apparatus for a user equipment, the apparatus comprising:
- a processor and a memory coupled to the processor, the processor configured to
- receive from a first cell operated in a licensed band, configuration information configuring a second cell operated in an unlicensed band,
- perform a listen-before-talk (LBT) procedure on the second cell,
- count a number of failures of the LBT procedure on the second cell, and
- transmit information based on the number of failures of the LBT procedure on the second cell, to the first cell operated in the licensed band, the information indicating the failure of the LBT procedure on the second cell.
A method used in a user equipment, the method comprising:
- receiving from a first cell operated in a licensed band, configuration information configuring a second cell operated in an unlicensed band,
- performing a listen-before-talk (LBT) procedure on the second cell,
- counting a number of failures of the LBT procedure on the second cell, and
- transmitting information based on the number of failures of the LBT procedure on the second cell, to the first cell operated in the licensed band, the information indicating the failure of the LBT procedure on the second cell.
