Abstract
A method for transmitting data via a terminal to a station of a digital telecommunications system. A first stream of data is encoded in data packets and a second stream of data is encoded in a frequency-hopping pattern. The data packets, in which the first stream of data is encoded, is consecutively transmitted in respective frequency bands of a frequency resource. The frequency bands are determined based on the frequency-hopping pattern in which the second stream of data is encoded.
Claims10
A method for transmitting data by a terminal to a station of a digital telecommunications system, comprising the steps of:
- simultaneously transmitting a first data stream and a second data stream to the station;
- encoding the first data stream in data packets;
- encoding the second data stream in a frequency-hopping pattern;
- and
- consecutively transmitting the data packets, in which the first data stream is encoded, in respective frequency bands of a frequency resource, the frequency bands are determined according to the frequency-hopping pattern in which the second data stream is encoded.
The reception method as claimed in claimed 5, further comprising the step of comparing the measurements of the frequency bands in which the data packets have been detected to a theoretical frequency-hopping pattern associated with the terminal.
A terminal of a digital telecommunications system comprises a transmitter configured to transmit data to a station, the transmitter:
- simultaneously transmits a first data stream and a second data stream to the station;
- encodes the first data stream in data packets;
- encodes the second data stream in a frequency-hopping pattern;
- and
- consecutively transmits the data packets, in which the first data stream is encoded, in respective frequency bands of a frequency resource, the frequency bands are determined according to the frequency-hopping pattern in which the second data stream is encoded.
