Abstract:
Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for multi-carrier listen before talk operations. In various embodiments, a transmitting device may assign one or more primary carriers to perform listen before talk (LBT) operations, with non-primary carriers performing a channel sensing operation at the end of the LBT operations of at least one primary channel. In various embodiments, the LBT operations at the primary carriers may use a shared random countdown number or an independent random countdown.

Claim (Index 25):
An user equipment (UE) configured for multi-carrier operation for license-assisted access (LAA) with an evolved node B (eNB), the UE comprising baseband circuitry configured to:\n identify one or more LAA messages for communication on one or more component carriers using one or more unlicensed channels corresponding to the component carriers; access a negative acknowledgement history associated with the one or more unlicensed channels; adjust a first contention window base on the negative acknowledgement history; generate a first random number associated with a first primary carrier of the one or more component carriers using the contention window; sense, during a back-off period based on the first random number, a first channel of the one or more unlicensed channels corresponding to the first primary carrier; sense, during a self-deferral period following the back-off period, the first channel; determine, based on the sensing during the back-off period and the self-deferral period, that the first channel is idle; and initiate transmission of the one or more LAA messages using the first channel based on the determination that the first channel is idle.
