Embodiment Construction

[0029] figure 1 A radio cell of a radio communication system is shown, which includes a base station BS and two mobile stations MS1 and MS2. The base station BS is connected to the network side equipment NE, where the connection can also be established through multiple other equipment. In addition, it is also possible that the network side equipment NE describes a part of the base station BS.

[0030] The following shall observe the data transmission by radio between the two mobile stations MS1 and MS2 and the base station BS. For this reason, it is used in the radio cell figure 2 The frequency band F described in. The frequency band may be, for example, a band for the uplink direction of the FDMA system. The frequency band is divided into sub-bands. The application of the narrow band sub-band has the advantage that the sub-band has a smaller frequency selectivity than the wide frequency band F. This frequency selectivity is achieved by multiplexing the signal between the tr...

Abstract

The invention relates to a method for communicating between radio stations of a radio communications system involving the use of at least one frequency band divided into a number of subbands (SB1, SB2, SBN). According to the invention, the type of division of the at least one frequency band into subbands (SB1, SB2, SBN) varies with time. The invention also relates to a device for dividing a frequency band into subbands, a device for transmitting, and to a device for receiving data according to the inventive method.

Description

Technical field [0001] The present invention relates to a method for communication between radio stations of a radio communication system in the case of applying at least one frequency band divided into a plurality of sub-bands, and a method for transmitting and receiving in a radio communication system A method for transmitting data between computers, wherein the data is transmitted on multiple sub-bands of frequency bands divided into sub-bands. [0002] In addition, the present invention relates to a device in a radio communication system for determining division of a frequency band into sub-bands, and a device for transmitting data and a device for receiving data in the radio communication system. Background technique [0003] In a radio communication system, information (such as voice, image information, video information, SMS (Short Message Service)) or information is transmitted through the radio interface between the transmitting radio station and the receiving radio statio...
