Abstract
Methods, systems, and devices are described for techniques for downlink (DL) scheduling and uplink (UL) scheduling in a shared radio frequency (RF)spectrum band. In some aspects, a wireless communication device may receive an UL data transmission grant associated with a channel of shared RF spectrum band. The wireless communication device may perform a channel readiness procedure associated with the channel. The wireless communication device may also transmit channel readiness information based at least in part on the channel readiness procedure to a base station. The channel readiness information may be transmitted via an uplink channel of a licensed RF spectrum band different from the shared RF band. In other aspects, a base station may schedule a data transmission on one or more channels of a shared RF spectrum band. The base station may transmit a data transmission grant for the scheduled data transmission to a wireless communication device.
