Content Document 1366r3 made several proposals to progress towards a PAR definition and propose a PAR text for scope and explanatory notes. A straw-poll on the “scope part” was 66Y, 19N, 68A. Several points for improvement were raised in the discussion and in different contributions This document proposes to use document 1470 as a basis PAR discussion Laurent Cariou (Orange)

Proposal for 802.11 HEW PAR Scope This amendment defines modifications to both the 802.11 physical layers (PHY) and the 802.11 Medium Access Control layers (MAC) in the 2.4 and 5GHz unlicensed bands that enable a (TBD significant or X-fold) increase in (TBD) throughput, as measured at the MAC data service access point (SAP), over all High Efficiency WLAN (HEW) stations in high density, indoor and (TBD pedestrian) outdoor, real-world environments, with both single and multiple management entities. Such improvements lead to significant area throughput increase. Slide 5 Laurent Cariou (Orange)

Proposal for 802.11 HEW PAR Explanatory Notes Text for Metrics (1) In contrast with previously developed 802.11 standards, this amendment will use system-level metrics representative of the performance obtained by stations in real-world network conditions, as opposed to the peak theoretical throughput achieved in ideal conditions. Since the values of these metrics will depend on the scenario, the focus will be on the relative improvement of these metrics compared to previous 802.11 amendments (802.11n in 2.4GHz and 802.11ac in 5GHz) The metrics will directly correspond to the user experience in the identified scenarios, including overall throughputs, distribution of throughputs (e.g. 5th percentile of user throughput CDF), throughput under load and satisfaction of the latency/jitter/packet loss constraints of applications. Slide 6 Laurent Cariou (Orange)

Proposal for 802.11 HEW PAR Explanatory Notes Text for Scenarios/Objectives (2) The amendment will be evaluated with a set of real-world scenarios representative of the main expected usage models that are mainstream and expected to suffer bottlenecks in the coming years: residential, enterprise, indoor and outdoor hotspots. HEW SG has initiated the creation of a high-level simulation scenario working document (ref: XXXXrX) to model these scenarios These scenarios highlight three categories of objectives to improve WLAN efficiency in WLANs: Significantly increase airtime usage efficiency in scenarios with a high density of STAs per BSS, by enhancing the capability to handle multiple simultaneous communications in both the spatial and frequency domains, in both the UL and DL  Significantly increase spectral reuse and manage interference between neighboring OBSS in scenarios with a high density of both STAs and BSSs, in cases where they may or may not share the same management entity Increase robustness to outdoor propagation characteristics (and increase uplink transmission reliability Slide 7 Laurent Cariou (Orange)

Proposal for 802.11 HEW PAR Explanatory Notes Text for backward compatibility (3) This new amendment shall include modes of operation that ensures backward compatibility with IEEE 802.11n and 11ac devices and provide for coexistence with legacy IEEE802.11 devices in the 2.4 and 5 GHz unlicensed bands.  Doesn’t the “across multiple BSS” duplicate the next bullet?

Annexes Slide 11 Laurent Cariou (Orange)

11n PAR Slide 12 Laurent Cariou (Orange) The scope of this project is to define an amendment that shall define standardized modifications to both the 802.11 physical layers (PHY) and the 802.11 Medium Access Control Layer (MAC) so that modes of operation can be enabled that are capable of much higher throughputs, with a maximum throughput of at least 100Mbps, as measured at the MAC data service access point (SAP). The scope of the MAC and PHY enhancements assume a baseline specification defined by 802.11 and its amendments and anticipated amendments a, b, d, e, g, h, i and j. The enhancements shall be to support higher throughput. The amendment shall not redefine mechanisms in the baseline that do not pertain to higher throughput. Some of the modes of operation defined in the HT amendment shall be backwards compatible and interoperable with 802.11a and/or 802.11g. Existing 802.11 standards are typically designated by their peak physical data rates. For example, 802.11a has a peak data rate of 54Mbps. This amendment has chosen to use a performance metric of throughput measured at the MAC data SAP. This amendment seeks to improve the peak throughput to at least 100Mbps, measured at the MAC data SAP. Depending on the scenario, this represents an improvement of at least 4 times the throughput obtainable using existing 802.11 systems. In order to make efficient use of scarce spectral resources in unlicensed bands, the highest throughput mode defined by the HT amendment shall achieve a spectral efficiency of at least 3 bits per second per Hertz for the PSDU. In the process of formulating this PAR, it was found that there are multiple user scenarios. Accordingly, the task group will undertake the following steps: 1. Identify and define usage models, channel models and related MAC and application assumptions. Initial usage models envisioned include hot-spot, enterprise and residential; others may be included. 2. Identify and define evaluation metrics that characterize the important aspects of a particular usage model. The evaluation metrics may include but are not limited to the items listed in Table 1, provided as an illustration of the format. 3. Develop a technical requirement specification. 4. Define a process for evaluations. The impact of an HT device on the operation of a legacy network shall be comparable to that of any other legacy device identified in the baseline defined above. Slide 12 Laurent Cariou (Orange)

11ac PAR This amendment defines standardized modifications to both the 802.11 physical layers (PHY) and the 802.11 Medium Access Control Layer (MAC) that enable modes of operation capable of supporting: A maximum multi-station (STA) throughput (measured at the MAC data service access point), of at least 1 Gbps and a maximum single link throughput (measured at the MAC data service access point), of at least 500 Mbps. Below 6 GHz carrier frequency operation excluding 2.4 GHz operation while ensuring backward compatibility and coexistence with legacy IEEE802.11 devices in the 5 GHz unlicensed band. Additional Explanatory Notes: (Item Number and Explanation) The project may include the capability to handle multiple simultaneous communications. • The multi-STA throughput is defined as the sum of the MAC SAP throughputs across all active transmissions within a set of STAs. • The 1 Gbps maximum multi-STA throughput may be achieved when considering multiple simultaneously actively-communicating STAs, e.g., a BSS with 1 access point (AP) and 3 or more STAs. • Though the primary metric used in the scope of the project deals with MAC SAP throughput, the intent is to provide enhancements over IEEE802.11n on the following inter-dependent performance indicators: throughput at the MAC data SAP, range of operation, aggregate network capacity (spectrum efficiency), power consumption (peak and average) Slide 13 Laurent Cariou (Orange)
