  1. SAMSUNG Partial MAC Proposal Summary Jon Rosdahl, KyungHun Jang, DJ Lee, Youngsoo Kim, Jin-Bong Chang, Taekwon Kim, Changyeul Kwon, Chil-Youl Yang Samsung November 15th, 2004 Jon Rosdahl, Samsung; et al

  2. Summary • Two-level frame aggregation • Supports multiple destinations and multiple rates in a PPDU • Nokia, Philips and Samsung merged this as MMRA • MAC header compression • Allows more efficient medium usage when multiple MPDUs are aggregated in a PSDU • A service period for aggregation exchanges • Initiated by MP frame and is combined with dynamic TDM and CSMA/CA without collision and unnecessary backoff delay • Smart Block ACK • Uses a two-level bitmap with a variable size instead of a fixed 128 octets as in the 802.11e Block ACK • Three error recovery mechanisms • Used with the two-level frame aggregation mechanism • Operating modes • For coexistence between legacy STAs and HT STAs Jon Rosdahl, Samsung; et al

  3. Questions from Joe Levy • 1)     How does your proposed method ofCSMA/CA without collision for uplink compare with scheduled allocation? 2)     Does MultiPoll frame allow power saving as in scheduled allocations?  How much, what are the potential power savings? Jon Rosdahl, Samsung; et al

  4. Answer – Joe levy - 1) • 1) Schedule allocation method needs extra overhead for resource request and allocation; however our method does not need extra overhead. The Scheduler must predict the amount of resource precisely to make a significant benefit. Jon Rosdahl, Samsung; et al

  5. Answer – Joe Levy – 2) • 2) Power saving can only occur as much as schedule allocation during the downlink period, but in the uplink period only the stations not involved in the exchange can use power save for the duration of the Long NAV. Jon Rosdahl, Samsung; et al
