  2. May 2015 Abstract • The proposal presents physical layer SIG structure for IEEE 802.11 aj (45GHz) in millimeter-wave WLAN communication. Slide 2 Shiwen He, Haiming Wang

  3. May 2015 Background • Challenges of future WLAN • Limited spectrum resources • High-speed data requirements • Features of future WLAN • Large bandwidth • Multiple channel mode • Multi-user • Multi-stream • 45GHz millimeter-wave communication • Digital home appliances • Ultra-high-speed (10Gbps) wireless applications Slide 3 Shiwen He, Haiming Wang

  4. May 2015 Technology Objects • The SIG frame structure try to achieve the following technical goals • Dynamic bandwidth • Multi-stream • Energy efficiency • Scrambler • Single-carrier & Multi-carrier compatible • Dynamic bandwidth Achieving dynamically channel bandwidth selection for 1080MHz BSS to enhance the adaptability in different channel environments and improve spectral efficiency. Slide 4 Shiwen He, Haiming Wang

  5. May 2015 Technology Objects • Multi-stream Achieve a multi-stream control to obtain the multiplexing gain. • Energy efficient communication Achieve energy efficient communication, i.e., allow non-AP STAs in TXOP power save mode to enter Doze state during a TXOP • Scrambler Scrambling effectively reduces the PAPR in OFDM system • Single-carrier & Multi-carrier Support single-carrier and multi-carrier simultaneously Slide 5 Shiwen He, Haiming Wang
