Techniques for downlink scheduling and uplink scheduling in a shared radio frequency spectrum band

摘要

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