8. A system for a gateway to communicate with a legacy terminal supporting a legacy air interface and a new terminal supporting a next generation air interface, the system comprising:
the gateway to assign a same carrier to the legacy terminal and the new terminal;
a MAC/RLC (Media Access Layer/Radio Link Control) layer
to receive a terminal identifier and an optional payload for transmission,
to determine if the terminal identifier is associated with the legacy terminal or the new terminal, and
to compose a burst header based on the association;
a burst formatter to format a burst comprising the burst header and the optional payload; and
a transmitter to transmit the burst on the same carrier, wherein
the legacy air interface defines one or more valid burst headers and one or more undefined burst headers,
the burst header is set, by the burst formatter, to one of the one or more valid burst headers when the burst is associated with the legacy terminal, and
the burst header is set, by the burst formatter, to one of the one or more undefined burst headers when the burst is associated with the new terminal.
