Abstract: Apparatuses, systems, and methods for transmitting a preamble. The UE may transmit a preamble to a base station in a random access channel (RACH). The RACH maybe located in unlicensed spectrum. The bandwidth of the preamble may cover a majority of a nominal channel bandwidth of the RACH. The UE may receive a random access response and establish a connection with the base station in response to receiving the random access response.

Abstract: Apparatuses, systems, and methods for a wireless device and base station transmitting and/or receiving request to send (RTS) and clear to send (CTS) messages in 5G New Radio. The RTS/CTS messages may be comprised within a single self-contained mini slot. The RTS/CTS message design may provide for link adaptation and/or beamforming.
