Abstract
The present invention aims at providing flexible and optimal configuration of an air interface of a transmitter in a radio system, more particularly a mobile radiotelephone system. According to the present invention, the data of a subscriber-specific control channel transmitted by the transmitter is transmitted with an adaptively modifiable frequency position or band width. The subscriber-specific control channel may include pilot symbols for channel evaluation, TCP symbols for power regulation, TFI symbols for transmitting transmission format information and other symbols, wherein the desired frequency position or band width can be individually adjusted for the individual symbol groups.
Claims20
A method for transmitting data of a subscriber-specific control channel in a radio system, comprising:
- providing an existing connection from a transmitter to a receiver of the radio system using a subscriber-specific data channel;
- and
- transmitting the data of the subscriber-specific control channel during the existing connection;
- and
- wherein the data of the subscriber-specific control channel is transmitted in multiple frequency bands that are at least partly contiguous, each of the multiple frequency bands having a frequency position with a mean frequency and a bandwidth, and wherein at least one of (a) the number of the multiple frequency bands, and (b) the bandwidth of at least one of the frequency bands is modified adaptively during the existing connection.
A device for transmitting data of a subscriber-specific control channel in a radio system, comprising:
- a controllable transmitter for transmitting data of the subscriber-specific control channel to a receiver;
- and
- a controller for activating the controllable transmitter based on control information, wherein data of the subscriber-specific control channel is transmitted by the transmitter during an existing connection with the receiver, the data of the subscriber-specific control channel being transmitted in multiple frequency bands that are at least partly contiguous, each of the multiple frequency bands having a frequency position with a mean frequency and a bandwidth, and wherein at least one of (a) the number of the multiple frequency bands, and (b) the bandwidth of at least one of the frequency bands is modified adaptively during the existing connection.
