Abstract
According to one embodiment of the invention, wireless spectrum and battery power conservation is achieved by through an adaptable multicast group communication scheme. This involves a method in which a request to join a multicast group is received by an access point or other multicast transmitting device. The request includes at least multicast transmission rate identifying a rate of modulation coding that can be supported by a multicast receiving device. Thereafter, membership to the multicast group may be granted where communications between with the access point are set at the multicast transmission rate requested.
