2. Summary Two-level frame aggregation MAC header compression
November 2004
November 2004
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 e Block ACK
Three error recovery mechanisms
Used with the two-level frame aggregation mechanism
Operating modes
For coexistence between legacy STAs and HT STAs
