    Abstract: Message formats and apparatus are described that serve to reserve access to a communication medium in a multi-cast system. A first message, a multicast request-to-send message, includes a duration field having information representing the reserved time for a communication medium, a multicast receiver address field, a multicast transmitter address field, a field that identifies the number of slots for a clear-to-send response, and a field that identifies the number slots for a not-clear-to-send response. A second message includes a duration field, and a multicast receive address field. The second message has a format that can be used as one of a clear-to-send message in response to a multicast request-to-send message, a cancel-clear-to-send message that cancels a data transmission after the clear-to-send message is sent, and a not-clear-to-send message in response to the multicast request-to-send message.
