P 802. 16 h technology features Coexistence between 802. 16 -based systems • Sharing of a frequency channel between colocated operators – Coexistence Frame (CX-Frame) – Each operator may use • different channel widths • different PHY profiles of 802. 16 • different cell sizes (macro, micro, nano cells) • No inter-operator messages needed for basic operation

P 802. 16 h technology features for improved coexistence with PRIMARY users • SSU (Specific Spectrum Users) – Coexistence Control Channel • Synchronized silence intervals enabling the cognitive detection – Examples: TV Transmitters, Wireless Mics, etc. – FCC regulations for LE TV bands: -114 d. Bm detection levels require absolute silence • NON-SSU – CXCBP - Contention-based protocol • Improved coexistence with 802. 11, other bursty systems • No inter-operator messages needed

Communication for improved inter-system coexistence • Inter-system messages – Spread information on the BS/SS radio power, antennae, location, Coexistence Frame usage, etc. – Control of interference between operators – Optimization of spectrum usage – Systems may belong to different operators • Inter-system protocols – Coexistence negotiation protocol (Token Protocol, developed within the European E 2 R II research project) • General spectrum controller is supported

Examples where 802. 16 h is needed Bands below 4 GHz • TV White Spaces (aprox. 300 MHz between 52… 692 MHz) – Data-base approach: resolves the Broadcast TV detection – Still required detection of wireless mics, etc. • -114 d. Bm power levels: detection is possible only with sync. silence • 802. 16 h Coexistence Control Channel enable the operation in TVWS • 2. 4 GHz – Reduced interference to 2. 3 GHz, 2. 5 GHz licensed bands – Europe: Requirements for Medium Access Protocol (EN 300328 V 1. 7. 1) for spectrum sharing with other devices • 3. 65 GHz – 3. 70 GHz, US – Contention-based protocol is required by FCC in the upper 25 MHz – Coexistence Assurance with 802. 11 y was done in 802. 19 Coexistence TAG • 5. 4 -5. 725 GHz – Europe: Requirements for Medium Access Protocol ((EN 301 893 v. 1. 5. 1) for spectrum sharing with other devices
