Abstract: A method is provided for minimizing cross-technology interference with data transmissions from a wireless device in a shared spectrum. The wireless device obtains data to be wirelessly transmitted in a transmission burst in a first radio access technology (RAT) format over a shared spectrum. The wireless device generates a preamble comprising assistance information related to the transmission burst. The preamble comprises a first preamble portion in the first RAT format and a second preamble portion in a second RAT format. The wireless device transmits the preamble followed by the transmission burst.

Abstract: Modifications to frame/subframe structure are presented herein so that a wireless device can transmit its data within a fraction of a subframe. The device obtains data to be transmitted in an unlicensed spectrum and determines whether an entire subframe is required to completely communicate the data. If the data is small enough to not require the entire subframe, then the device generates a burst transmission to minimize the time period of the subframe used to communicate the data. The device transmits the burst transmission and a parameter indicating the duration of the burst transmission.
