When operating in unlicensed radio frequency spectrum bands, wireless devices such as the AN 110 and UE 105 may employ LBT procedures to ensure the channel is clear before transmitting data. In some cases, operations in unlicensed bands may be based on a carrier aggregation (CA) configuration in conjunction with CCs operating in a licensed band. Operations in unlicensed spectrum may include DL transmissions, UL transmissions, or both. Duplexing in unlicensed spectrum may be based on frequency division duplexing (FDD), time division duplexing (TDD) or a combination of both. Additionally or alternatively, a grant-free UL transmission may be used in the unlicensed spectrum to avoid quadruple contention.
