  2. Monisha Ghosh (InterDigital) Abstract • This contribution outlines some of the requirements for supporting backhaul in NG 60.

  3. Monisha Ghosh (InterDigital) Recap of Backhaul Usage Model • Small cells are becoming increasingly important for cellular and Wi-Fi [1]. • Requirements: • ~ 2 Gbps peak per small-cell data rate • 100 m – 150 m cell size • Latency: ~ 5 ms, one way, end-to-end. • Support for bursty traffic • mmW backhaul enabled by 802.11ad/NG60: • Leverage availability of low-cost chipsets, driven by volume (ABI Research: 1.5 billion chipsets by 2018)

  4. Monisha Ghosh (InterDigital) What does backhaul need from NG 60? • Multi-hop capability. • Existing 802.11ad specification may not be sufficient for extended range applications. • Enhanced QoS guarantees: • Beyond current 802.11ad specification. • Higher data rate • Will be addressed by planned high-data rate enhancements (MIMO, channel bonding, etc.). MU-MIMO may be beneficial as well. • Enhanced discovery methods for longer range • Discovery range = Communication range.

  5. Monisha Ghosh (InterDigital) Use cases enabled • Solutions that meet the backhaul requirements will also provide benefits to other use cases of interest: • High-data-rate indoor applications [2], such as video streaming, would benefit from extended range. • Deployment of infrastructure NG60 APs would benefit from the possibility of self-backhaul, leading to lower-cost.

  6. Monisha Ghosh (InterDigital) Conclusions • Support for backhaul in NG60 may require MAC only or PHY/MAC enhancements to current 802.11ad. • Support for backhaul in NG60 will enable new deployment and use scenarios that may not be fully served by 802.11ad. • Support for backhaul is complementary to high-rate enhancements such as MIMO, higher-order constellation, channel bonding etc.
