  1. Suggested PAR Changes Authors: • Date:2014-01-20 Yee et.al., MediaTek

  2. Abstract • This document provides some comments on the 802.11 HEW Draft PAR & 5C Document based on 13/1410r3. Yee et.al., MediaTek

  3. Comment Areas • Reliability • Latency • Mobile Yee et.al., MediaTek

  4. Yee et.al., MediaTek RELIABILITY

  5. Comment on 5.5 and 8.1 • In 13/1410r3: • In section 5.5 ‘Need for the Project’, P3L40: “With the real-time performance requirements of some of these applications, WLAN users demand improved reliability in delivering their applications. ” • Comment: While ‘reliability’ is desirable, what does it mean here in the context of densely deployed real-time applications in the presence of interference? If we mean to say ‘reliably’ meeting real-time performance requirements, it is better to not add ‘reliability’ as a metric. • Suggested Change: “WLAN users increasing demand that Withthe real-time performance requirements of some of these applications are met in dense deployments and in the presence of interference , WLAN users demand improved reliability in delivering their applications.” Yee et.al., MediaTek

  6. Comment on 5.5 and 8.1 (cont’d) • In 13/1410r3: • In section 8.1 ‘Additional Explanatory Notes’, P5L23, as one of the three categories of objectives to improve WLAN efficiency: “Increased robustness to outdoor propagation characteristics and increase uplink transmission reliability” • Comment: How is ‘reliability’ different from robustness? In the referenced Simulation Scenarios document 11-13-1001r5, only ‘robustness’ is mentioned and not ‘reliability’. • Suggested Change: “Increased robustness toin outdoor propagation environments characteristicsand increase uplink transmission reliability” Yee et.al., MediaTek

  7. Strawpoll • Do you accept the Reliability related changes proposed on slides 5 and 6? • Y/N/A Yee et.al., MediaTek

  8. Yee et.al., MediaTek Latency

  9. Comment on 8.1 and 5.2b • In 13/1410r3: • Section 5.2b ‘Scope of the project’: “average throughput per station ” is the only metric mentioned. • Section 8.1 ‘Additional Explanatory Notes’, P4L39: “These metrics, along with the satisfaction of the packet delay and the packet loss requirements of applications, will directly correspond to user experience in identified scenarios.” • Comments: ‘delay’ is described as another metric on par with average throughput per station, but it is not alluded to in the scope. • Suggested Change in 5.2.b: “at least two (2) times improvement in applicable metrics such as the average throughput per station ” Yee et.al., MediaTek

  10. Strawpoll • Do you accept the changes proposed on slide 9? • Y/N/A Yee et.al., MediaTek

  11. Yee et.al., MediaTek Mobile

  12. HEW’s Role in Mobile Offloading • In 13/1410r3 : • Section 8.1 clearly identified: ‘indoor and outdoor hotspots’ as a main expected usage model, which includes offloading operator mobile traffic as a primary application. • Mobile devices account for the bulk of WLAN traffic growth in recent years and the trend will continue. HEW needs more visibility into the future of mobile offloading. • In addition, we all know 3GPP is investigating operating in the unlicensed bands. We need more information and not design HEW in the blind. • Suggested Change: • Add to the end of Section 8.1 “This amendment should take into account developments in 3GPP related to future mobile offload and coexistence needs.” • In 7.2 “Joint Development” , Replace “No” with “Yes, liaison should be establish with 3GPP to better understand future mobile offload and coexistence needs.” Yee et.al., MediaTek
