Listen before talk techniques in shared millimeter wave radio frequency spectrum

A method for wireless communication at a base station, comprising:

• allocating uplink resources to a user equipment (UE) for an uplink transmission of uplink data from the UE to the base station in a shared millimeter wave (mmW) radio frequency spectrum band;
• transmitting an uplink grant to the UE indicating the uplink resources;
• and
• monitoring for the uplink transmission from the UE using the uplink resources indicated in the uplink grant, wherein the UE is to perform a listen-before-talk (LBT) procedure prior to the uplink transmission.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor,
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive an uplink grant from a base station that indicates uplink resources for transmission of uplink data from the UE to the base station in a shared millimeter wave (mmW) radio frequency spectrum band;
• perform, responsive to receiving the uplink grant, a listen-before-talk (LBT) procedure to determine that the shared mmW radio frequency spectrum band is available for the transmission of the uplink data;
• and
• transmit, based at least in part on the shared mmW radio frequency spectrum band being available for the transmission of the uplink data, the uplink data to the base station using the uplink resources indicated in the uplink grant.
