1. A method comprising:

  • receiving, at a hub of a satellite communication system, a request from a first satellite communication terminal;

    determining, at the hub, that one or more responses corresponding to the request are associated with a multicast group;

    selecting transmission characteristics for transmitting the one or more responses in a multicast transmission, wherein the selecting comprises;

    calculating, using a cost function, a cost for selecting the transmission characteristics instead of threshold transmission characteristics that are determined in accordance with a reception capability of only the first satellite communication terminal, wherein the transmission characteristics are at least as robust as the threshold transmission characteristics; and

    selecting the transmission characteristics instead of the threshold transmission characteristics if the cost is less than or equal to a cost threshold; and

    transmitting the one or more responses in the multicast transmission using the transmission characteristics.
