Abstract

A two-stage signaling concept for a datastream to be transmitted from a transmitter to a receiver is proposed. At the transmitter side, a plurality of frame headers are generated, each frame header including data transmission parameters for payload data. A super-frame header for a super-frame is generated. The super-frame includes a plurality of frames, each frame including one of the frame headers and payload data. The super-frame header indicates a set of super-frame-constant frame header transmission parameters for the frame headers of the plurality of frames of the super-frame. A receiver evaluates the super-frame header of to obtain the super-frame-constant frame header transmission parameters, which are then used to evaluate the plurality of frame headers PLH to retrieve the data transmission parameters. The proposed concept provides added flexibility, less signaling overhead, and/or an option of improved receiver performance at low SNR levels.
