Abstract:
1. A method for transmission of data comprising: a transmitting node sending a request message to a plurality of receiving nodes, the request message identifying at least one time slot that is available for the transmitting node to transmit a data transmission; a first receiving node of the plurality of receiving nodes transmitting a first time slot grant message in response to the request message, the first time slot grant message indicating at least one first time slot that is available for the first receiving node to receive the data transmission from the transmitting node, the at least one first time slot matching at least one time slot identified in the request message; a second receiving node of the plurality of receiving nodes transmitting a second time slot grant message in response to the request message, the second time slot grant message indicating at least one second time slot that is available for the second receiving node to receive the data transmission from the transmitting node, the at least one second time slot matching at least one time slot identified in the request message; the transmitting node receiving the first and second time slot grant messages; the transmitting node evaluating the first and second time slot grant messages to determine at least one available time slot for transmitting the data transmission to the first and second receiving nodes; the transmitting node transmitting at least one confirmation message to the first and second receiving nodes in response to the first and second received time slot grant messages, the at least one confirmation message confirming the at least one available time slot that is to be used for transmitting the data transmission from the transmitting node; the transmitting node transmitting the data transmission in the at least one available time slot identified in the at least one confirmation message to the first and second receiving nodes; and wherein the request message comprises a demand level and a demand persistence.
