Abstract
A base station transmits to a wireless device configuration parameters of a first bandwidth part (BWP) and a second BWP of an unlicensed cell. The base station determines a first contention window for a first listen before talk (LBT) procedure for the first BWP. The determination of the first contention window being based on hybrid automatic repeat request (HARQ) feedback of one or more transmissions via a first channel of the first BWP. Based on switching from the first BWP to the second BWP, as the active BWP, the base station determines a second contention window for the LBT procedure of a second channel of the second BWP. The second coantention window being the minimum contention window of a plurality of contention windows. Finally, the base station receives, via the second BWP, a transport block based on the second LBT procedure using the second contention window indicating a clear channel.
