The use of at least two distinct MAC multicast addresses are used to separate the first multicast frame transmissions from subsequent multicast frame re-transmissions. Thereby enabling legacy devices to ignore duplicate retransmitted multicast frames, because the duplicate frames are sent using a multicast address they do not listen to. Thus, the legacy devices are not confused with duplicated frames. In addition, new devices benefit from the retransmissions sent on the second multicast address and can re-order the frames before delivering to the applications or upper layers; thereby improving the QoS for the multicast."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for providing reliable multicast in a wireless communication system","description":"A method and apparatus is described which provides reliable multicasting in a WLAN.
