A system () schedules candidate packets () for transmission from a communication platform (), the communication platform () being allocated a plurality of transmission resources (). The system () includes a processing element () for receiving the packets () and establishing a transmission priority () for each of the packets () according to a desired quality of service. The packets () are stored in a candidate packet buffer () as candidate packets () in accordance with the established transmission priority (). The system () further includes an interference resolver () that executes an interference resolution process () to concurrently consider transmission resource availability, spatial separation, and temporal separation variables when scheduling the candidate packets () for transmission from the communication platform ().

Method and system for scheduling packets for transmission from a wireless communication platform

A method and apparatus for steering beams modulated from a mobile platform in a manner that reduces overall platform payload processing, and therefore payload weight and power requirements. According to the present invention, a beam steering data calculator ( ) generates a table of beam steering data sets ( ), with each data set corresponding to a specific beam-pointing angle mapped to a corresponding cell on the surface of the earth. A data set that corresponds to a received downlink cell address ( ) is read out from the table and mapped to the downlink address, and an output angle of a modulated vehicle beam ( ) that transmits a data packet to the cell address is corrected to correspond to the beam-pointing angle of the read-out data set. The generated table of beam steering data sets ( ) is then re-used for an application-specific quantization time for mapping subsequently-received downlink addresses with beam steering data sets, thereby obviating the need to provide real-time updates of data sets on a packet transmit interval basis. In addition, the present invention is capable of compensating for numerous other causes of beam-pointing error, thereby improving overall beam-pointing accuracy.
