Abstract
Techniques for adjusting a contention window (CW) for transmissions in a shared radio frequency spectrum band may include identifying a number of nodes attempting to transmit using a channel of a shared radio frequency spectrum band and determining a target CW based on the number of nodes attempting to transmit. A new CW value may then be determined based on a prior CW value and the target CW value, and a listen-before-talk (LBT) procedure (e.g., a clear channel assessment (CCA)) to access the channel of the shared radio frequency spectrum band may be performed to access the channel.
