Abstract
A method and radio station for transmitting information, wherein frequency channels of a frequency band are arranged in accordance with a first coarse raster system and a second fine raster system, the raster system being used, in particular, for performing an efficient frequency channel search and for the effective coding of the frequency channels.
Claims11
A method for transmitting information between a base station and a mobile station, in which at least one frequency band which contains a plurality of frequency channels is available to at least one network operator for transmitting the information, the method comprising the steps of:
- transmitting the information via radio signals substantially within at least one of the plurality of frequency channels at least from time to time;
- arranging carrier center frequencies of the plurality of frequency channels within the frequency band according to a first coarse raster system, a raster pattern of the first coarse raster system essentially corresponding to a width of one frequency channel;
- displacing the plurality of frequency channels with respect to the first coarse raster system in accordance with a second fine raster system;
- and
- restricting at least a range of definition of the fine raster system.
A radio station, comprising:
- a transmitting portion for transmitting information in a frequency band which contains a plurality of frequency channels, the information being transmitted via radio signals substantially within one of the plurality of frequency channels at least from time to time, carrier center frequencies of the frequency channels being arranged within the frequency band in accordance with a first coarse raster system having a raster pattern substantially corresponding to a width of one of the plurality of frequency channels such that an arrangement of the frequency channels can be displaced with respect to the first coarse raster system in accordance with a second fine raster system;
- and
- a storing portion for storing information on a restriction of a range of definition of at least the fine raster system.
