1. A system comprising:
- one or more hardware processors, the system being configured to execute instructions, with the one or more hardware processors, to cause performance of operations comprising;
granting a request from a first device to join a particular multicast group;
receiving, from the first device, a first modulation and coding rate;
based at least on the first modulation and coding rate received from the first device, selecting a second modulation and coding rate for the particular multicast group.

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.

12. A system comprising:
-
one or more hardware processors, the system being configured to execute instructions, with the one or more hardware processors, to cause performance of operations comprising; granting a request from each of a plurality of devices to join a particular multicast group; receiving a first feedback information regarding multicast communications that (a) are associated with the particular multicast group and (b) were received by a first device of the plurality of devices; receiving a second feedback information regarding multicast communications that (a) are associated with the particular multicast group and (b) were received by a second device of the plurality of devices, the second feedback information being different from the first feedback information; adjusting a modulation and coding rate for the particular multicast group based on the first feedback information and the second feedback information; wherein the second device comprises a hardware processor. - View Dependent Claims (13, 14, 15, 16)
