1. A method comprising:
- granting, by a network device, a request from a first device to join a particular multicast group;
receiving, by the network device from the first device, a first modulation and coding rate;
selecting, by the network device, a second modulation and coding rate for the particular multicast group based at least on the first modulation and coding rate received from the first device;
receiving, by the network device, feedback information regarding multicast communications that (a) are associated with the particular multicast group and (b) are received by the first device;
estimating, by the network device, a frame loss for the first device based at least on the feedback information; and
adjusting, by the network device, the second modulation and coding rate for the particular multicast group based at least on the frame loss for the first device.

Abstract
According to one embodiment of the invention, wireless spectrum and battery power conservation is achieved through an adaptable multicast group communication scheme. This involves a method for controlling the multicast transmission rate based on a first operation of receiving information from a multicast receiving device that is a member of a multicast group. Based on this information and potentially other information from other member devices, the modulation and coding rate for the multicast group is altered.
