(54) Title: SIGNATURE SEQUENCE FOR SYSTEM IDENTIFICATION IN A SHARED SPECTRUM (57) : Aspects of the disclosure relate to wireless communication systems 600 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 602 utilizing different radio access technologies). Coexistence between the different sys- tems on the shared spectrum may be provided by utilizing a technology-neutral sig- nature waveform such as a signature sequence. A device or system may monitor a 60 shared spectrum channel for the signature waveform, and when detected, may de- termine whether the shared spectrum is available for that system, or busy as occu- 610-, pied by another system. When the shared spectrum channel is idle, the device or system may reserve the channel by transmitting the signature waveform. Other as- pects, embodiments, and features are also claimed and described.
