RECEIVER-BASED LISTEN BEFORE TALK TECHNIQUES IN SHARED MILLIMETER WAVE RADIO FREQUENCY SPECTRUM

摘要

Methods, systems, and devices for wireless communications are described for receiver-based listen-before-talk (LBT) in systems that use shared radio frequency spectrum. A scheduling device may provide a pre-grant indication of a data transmission. The data transmission may be transmitted via a shared millimeter wave (mmW) radio frequency spectrum band, and a LBT procedure may be performed at a receiving device responsive to the pre-grant indication, to determine that the shared mmW radio frequency spectrum band is available for the data transmission. An indication may be transmitted to a transmitting device to indicate that the receiving device has successfully performed the LBT procedure, which may act as a trigger for the transmitting device to start the data transmission.
