Abstract
In a device for data transmission having a central station and a plurality of subscribers, in addition to useful signal data phases, signaling data phases are provided for the downlink and uplink in a transmission frame (3). The signaling data phases for the downlink are divided into signaling data phases related to the central station and related to the protocol. The positions of these two signaling data phases are identified directly or indirectly by identifiers.
Claims15
A method for transmitting data on a common medium in a system including a central station and a plurality of subscribers, data packets in the system being transmitted from the central station to the subscribers (downlink) and from the subscribers to the central station (uplink), the central station being responsible for coordinating media access via a protocol-oriented transmission frame, the transmission frame including a useful signal data phase and a signaling data phase for the uplink and the downlink, the method comprising:
- dividing the signaling data phase for the downlink into a signaling data phase related to the central station and a protocol-related signaling data phase;
- providing at least one identifier of a position in time of the protocol-related signaling data phase of the downlink in the transmission frame;
- and
- including the at least one identifier directly in the signaling data phase for the downlink.

- dividing the signaling data phase for the downlink into a signaling data phase related to the central station and a protocol-related signaling data phase;
- providing a first identifier of a position in time of the protocol-related signaling data phase of the downlink in the transmission frame;
- and
- deriving the first identifier of the position in time of the protocol-related signaling data phase of the downlink from a second identifier, the second identifier being provided for a position of the signal data phase related to the central station.
