Abstract

Time division multiple access (TDMA) systems for time multiplex communication between multiple stations (e.g., via a satellite space link) utilize a complex time framing structure of repetitive frames, superframes of multiple frames, and master frames of multiple superframes. The frames are organized into variable duration transmission bursts of the various participating stations, which are timed to interleave without overlap in the transmission facility.

Time Frame Structure for TDMA Communication

Time division multiple access (TDMA) systems for time multiplex communication between multiple stations (e.g., via a satellite space link) utilize a complex time framing structure of repetitive frames, superframes of multiple frames, and master frames of multiple superframes. The frames are organized into variable duration transmission bursts of the various participating stations, which are timed to interleave without overlap in the transmission facility.

The stations utilize specific portions of frames, known as order-wire (OW) channels, for reallocation of burst interval assignments on a relative demand basis; whereby the available time resource is most efficiently utilized. This description deals with a method of ordering the station OW transmissions for such reallocation.

According to the present method one station, predesignated as primary or master station, performs a predetermined reallocation computation, based on its analysis of the monitored order-wire information content of all station transmissions. The computation is performed over a super-frame interval and a message, indicating the proposed reallocation assignment of each station, is sent to the respective station in the OW time slot assigned to the recipient station. Allowing for transit time due to signal delays in the transmission facility, the stations echo their respective assignments within respective OW transmissions.

Allowing for further transit t...
