Embodiment Construction

[0019] start will refer to figure 1 Describe the structure and function of an exemplary transmit frame, then refer to Figure 1-3 The function of the method according to the invention is explained. In some cases, the same elements in similar figures are not repeatedly shown and described.

[0020] figure 1 An exemplary transmit frame 20 is shown. In a communication system, a message based on a transmission frame 20 is transmitted. A transmission frame 20 is a range defined by a temporal scale and a spectral scale within which a message may be transmitted. The transmit frame 20 includes a fixed temporal extent 34 and a variable spectral extent 14 . The spectral range 14 of the transmitted frame 20 is specified by a remote user in communication, for example a base station in a mobile radio system. Local users in communication, such as mobile radios, use the designated spectrum range 14 to transmit their messages.

Abstract

A method detects a bandwidth that is transmitted by a transmitter in a radio communications system, which is based on transmission frames. The transmission frames comprise a fixed time extension and a variable spectral extension. The transmission frames consist of a plurality of sub-units. Each sub-unit of the transmission frames contains a control channel, which is subdivided into two sub-control channels. The two sub-control channels are arranged at the spectral edges of the sub-units of the transmission frames. The transmitted bandwidth is investigated by determining the spectral extension of the transmission frame. The spectral extension of the transmission frame is determined by determining the spectral position of the sub-control channels in the sub-units of the transmission frames.

Description

technical field [0001] The present invention relates to a method and a system for detecting the bandwidth of a signal transmitted by a transmitter, in particular a mobile radio device specific to the LTE (Long Term Evolution) standard for fourth generation mobile telephony. Background technique [0002] Traditionally, in a radio communication system, one or more channels are assigned by a base station to a mobile subscriber. Mobile users may exclusively use the channel or channels. If the mobile subscriber leaves the channel or channels assigned to him, for example by transmitting with a greater bandwidth, the transmissions provided in adjacent frequency ranges can be disrupted. This can occur if a mobile user incorrectly receives or responds to a channel assignment incorrectly. These difficulties are usually not specifically addressed. Correspondingly, channel assignments are checked or reassigned only when transmission difficulties are encountered, for example due to la...
