IEEE Std 802.15.3b-2005 (Amendment to IEEE Std 802.15.3-2003) IEEE Standard for Information technology— Telecommunications and information exchange between systems— Local and metropolitan area networks— Specific requirements Part 15.3: Wireless Medium Access Control (MAC) and Physical Layer (PHY) Specifications for High Rate Wireless Personal Area Networks (WPANs): Amendment 1: MAC Sublayer Approved 28 March 2006 American National Standards Institute Approved 6 December 2005 IEEE-SA Standards Board Abstract: This amendment provides corrections and optimizations to IEEE Std 802.15.3-2003. The management service access points (SAPs) have been completely updated to create a consistent,logical interface. As a consequence, most of the message sequence charts (MSCs) in the medium access control (MAC) functional specification have been updated as well. Channel time usage is more efficient with the addition of multiple contention periods, releasing channel time, implied acknowledgment, and mullticast groups. Keywords: channel time reuse, handover, implied acknowledgment, multicast, wireless personal area network, WPAN
