METHOD AND APPARATUS FOR MANAGING ADDRESSES AND CONNECTIVITY ARRANGEMENTS FOR TRANSPORTING MULTICAST DATA IN A WIRELESS NETWORK
First Claim
1. A method for managing multicast/groupcast (MG) data communications in a wireless system comprising an access point (AP) device, a source device that is separate from the AP device and one or more sink devices that are separate from both the AP and source devices, the method comprising:
- allocating a multicast address by the source device; and
wirelessly transmitting MG data from the source device to the one or more sink devices using the allocated multicast address.

Abstract
The present invention provides methods and apparatuses for managing multicast addresses and connectivity arrangements for transporting multicast data in a wireless network. According to certain aspects, embodiments of the invention enable allocation of multicast addresses to facilitate reliable multicast/groupcast transmissions by any device in a wireless network, and not just an access point, as well as in wireless networks where there is no support for 802.11aa. According to certain other aspects, embodiments of the invention allow for multicast transmission to sinks in a wireless network that are not reachable to the source device even in presence of an access point that does not support IEEE 802.11aa.
