IEEE 802.11-14/1510r0 Summary of PAR and CSD Discussion - November 2014
This document captures the discussions and progress made by the NG60 Study Group in drafting the Project Authorization Request (PAR) and Criteria for Standards Development (CSD) in November 2014. The submissions reviewed focused on various aspects such as usage models, backhaul support, power efficiency, and improving achievable throughput to meet the growing demands of WLAN usage and new applications. The need for operation in 60 GHz frequency bands, backward compatibility with existing IEEE 802.11ad devices, and enhancing spatial reuse of transmissions were key points discussed.

November 2014 doc.: IEEE 802.11-14/1510r0 Abstract This document summarizes the progress of the NG60 Study Group drafting the PAR and the CSD in September 2014 Interim. Submission Slide 2 Edward Au (Marvell Semiconductor)
November 2014 doc.: IEEE 802.11-14/1510r0 Overall Summary Heard a number of submissions that assist in drafting the PAR and the CSD: 11-14/1160r0, Ultra Short Range (USD) Communications Usage Models for NG60, Lei Huang (Panasonic) 11-14/1166r0, NG60 Use-Cases, Takuma Takada (NTT DoCoMo) 11-14/1185r0, NG 60 Usage Models, Rob Sun (Huawei Technologies) 11-14/1249r1, Backhaul Support in NG 60, Monish Ghosh (InterDigital) 11-14/1151r1, 802.11 NG60 SG Proposed PAR , Carlos Cordeiro (Intel) 11-14/1152r1, IEEE 802.11 NG60 SG Proposed CSD , Carlos Cordeiro (Intel) Submission Slide 3 Edward Au (Marvell Semiconductor)
November 2014 doc.: IEEE 802.11-14/1510r0 PAR Recap of the Submission 11-14/1152r1 1 MAC + several PHYs [5.2] At least one mode of operation capable of supporting at least TBD gigabits per second average throughput per station [5.3] Power efficiency is maintained or improved [5.3] Operation is defined in 60 GHz frequency bands [5.3] Backward compatibility and coexistence are enabled with legacy IEEE 802.11ad devices [5.3] Submission Slide 4 Edward Au (Marvell Semiconductor)
November 2014 doc.: IEEE 802.11-14/1510r0 PAR Recap of the Submission 11-14/1152r1 Motivation of increasing achievable throughput of IEEE 802.11 devices substantially because of the growth of WLAN usage and new applications demanding additional capacity [5.5] Comparison with wired counterparts Speed of wired interfaces far exceed 10 Gbps, e.g., Displayport, Ethernet, HDMI, USB New usage models e.g., indoor/outdoor backhaul, offload, wireless display, wireless docking Submission Edward Au (Marvell Semiconductor) Slide 5
November 2014 doc.: IEEE 802.11-14/1510r0 PAR Recap of the Submission 11-14/1152r1 Definition of power efficiency is provided [8.1] A set of typical deployment scenarios representative of main expected usage models is introduced [8.1] The need to improve spatial reuse of multiple simultaneous nearby transmission is mentioned [8.1] Submission Slide 6 Edward Au (Marvell Semiconductor)
November 2014 doc.: IEEE 802.11-14/1510r0 CSD Recap of the Submission 11-14/1152r1 Market drivers [1.2.1] Analyses forecast the need of multiple gigabit per second speeds for new throughout-demanding applications and usage models in various segments Wide bandwidth channels available in 60 GHz frequency band can be used to support such high throughput usages Distinct Identity [1.2.3] No other IEEE 802.11 projects focus on increasing the throughput per station beyond TBD gigabits per second Different from other IEEE 802 projects that this amendment focuses on higher throughput WLAN technology in the 60 GHz frequency band Submission Slide 7 Edward Au (Marvell Semiconductor)
November 2014 doc.: IEEE 802.11-14/1510r0 CSD Recap of the Submission 11-14/1152r1 Technical Feasibility [1.2.4] There are already IEEE 802.11ad devices operating in the 60 GHz frequency band available in the market IEEE 802.11 NG60 SG has reviewed many presentations indicating that the proposed functions are technically feasible Submission Slide 8 Edward Au (Marvell Semiconductor)
November 2014 doc.: IEEE 802.11-14/1510r0 Issues to be addressed PAR Define the TBD value of the performance metric in [5.3] CSD Define the TBD value of the performance metric in [1.2.3] Submission Slide 9 Edward Au (Marvell Semiconductor)
