Claims
- 1. A signalling method in a wireless digital telecommunication system between a base station and a terminal, the method comprising steps ofgenerating the signals between the base station and the terminal from bursts comprising symbols, the bursts comprising a known training sequence, generating from symbols a second training sequence of the same length as the known training sequence, generating a burst comprising said second training sequence, using the burst comprising said second training sequence for transmitting at least one signalling message, and using stealing symbols in the burst comprising said second training sequence for specifying the signalling message to be transmitted.
- 2. A method as claimed in claim 1, further comprising indicating the existence of said signalling message, in response to the received burst comprising said second training sequence.
- 3. A method as claimed in claim 2, further comprising restricting the number of the training sequences to be used to two.
- 4. A method as claimed in claim 3, further comprisingsending user data in the burst comprising said known training sequence and sending in the burst comprising said second training sequence at least one of the following: signalling data, user data.
- 5. A method as claimed in claim 1, wherein the burst comprising said second training sequence is used for transmitting FACCH signalling according to the GSM system.
- 6. A method as claimed in claim 1, wherein the burst comprising said second training sequence is used for transmitting SACCH signalling according to the GSM system.
- 7. A method as claimed in claim 1, wherein the method is used in a packet-switched wireless telecommunication system.
- 8. A method as claimed in claim 1, wherein the method is used for adjusting the transmission power of the mobile station and the base station.
- 9. A method as claimed in claim 1, wherein the method is used for determining the used coding method.
- 10. A wireless digital telecommunication system for signalling between a base station and a terminal, where the signals to be transmitted over a radio connection between the base station and the terminal comprise bursts generated from symbols, the bursts comprising a known training sequence, the system comprising at least one transmitter and at least one receiver, whereofthe transmitter comprises means for generating said training sequence, means for generating a second training sequence of the same length as the known training sequence and means for generating a burst comprising said second training sequence and for coding a signalling message into said burst and the receiver comprises means for identifying said training sequence, means for receiving the burst comprising said second training sequence, means for identifying said second training sequence and means for decoding the coded signalling message in said burst, wherein at least one stealing symbol in the burst comprising said second training sequence is arranged to specify the contents in the signalling message to be transmitted.
- 11. A telecommunication system as claimed in claim 10, wherein the receiver is arranged to indicate the existence of said signalling message, in response to the received burst comprising said second training sequence.
- 12. A telecommunication system as claimed in claim 11, wherein the number of the training sequences to be used in the system is restricted to two.
- 13. A telecommunication system as claimed in claim 12, whereinsaid burst comprising the known training sequence is arranged to transmit user data and said burst comprising the second training sequence is arranged to transmit at least one of the following: signalling data, user data.
- 14. A telecommunication system as claimed in claim 10, wherein said burst comprising the second training sequence is arranged to define the coding method to be used.
