Abstract:
Aspects of the disclosure relate to wireless communication systems configured to share a shared spectrum with one or more other systems (e.g., other operator networks utilizing the same radio access technology, and/or other networks utilizing different radio access technologies). Coexistence between the different systems on the shared spectrum may be provided by utilizing a technology-neutral signature waveform such as a signature sequence. A device or system may monitor a shared spectrum channel for the signature waveform, and when detected, may determine whether the shared spectrum is available for that system, or busy as occupied by another system. When the shared spectrum channel is idle, the device or system may reserve the channel by transmitting the signature waveform. Other aspects, embodiments, and features are also claimed and described.

Claim (Index 6):
The method of  claim 1 , further comprising:\n monitoring the shared spectrum channel to detect a transmission of the technology-neutral signature waveform by another device, the monitoring comprising:\n sensing a signal on the shared spectrum channel; \n determining an autocorrelation of the sensed signal; and \n if the autocorrelation is greater than an autocorrelation threshold, determining that the shared spectrum channel carries the technology-neutral signature waveform; \n if the technology-neutral signature waveform is detected from a first system the wireless communication device is configured to use, monitoring the shared spectrum channel for the first technology-specific waveform corresponding to the first system; if the technology-neutral signature waveform is detected from a second system known to the wireless communication device, forgoing to use the shared spectrum channel for a back off time, or monitoring the shared spectrum channel for a second technology-specific waveform corresponding to the second system; and if the technology-neutral signature waveform is detected from a third system with an unknown signature waveform, forgoing to use the shared spectrum channel for the back off time.
