Embodiment Construction

[0025] The radio communication system represented in accompanying drawing 1 corresponds in its structure to the known GSM-mobile radio communication network, and this mobile radio communication network is formed by a lot of interconnected network, and the mobile switching center that establishes entrance with fixed network PSTN Composed of MSCs. Furthermore, the mobile switching centers MSC are connected to at least one radio resource allocation device RNM in each case. Each such device RNM may in turn be connected to at least one base station BTS, in the case shown a first base station BTS1 and a second base station BTS2. The base stations BST1 , BST2 are radio stations which, via radio interfaces, can establish communication links with further radio stations, in the case shown, with mobile radio stations MS1 to MS4 .

[0026] 1 shows, for example, three communication connections V1, V2, V3 for the transmission of application data and signaling information between mobile rad...

Abstract

The present invention relates to a method and apparatus for transmitting communication connection application data according to a CDMA subscriber separation method from / to a first and a second radio station located within the radio supply area of ​​a first base station. The first and second CDMA codes assigned to the first and second radio stations are signaled. In addition, the second CDMA code assigned to the second radio station of the first radio station is signaled, and the first CDMA code and the second CDMA code are then used by the first radio station to detect the transmitted application data.

Description

[0001] The application for the present invention is a divisional application of the patent application with the same title filed on August 26, 1998 and with application number 98808747.2. technical field [0002] The invention relates to a method and a device for transmitting application data in a radio communication system, in particular a mobile radio communication system. Background technique [0003] In communication systems information (for example speech, image information or other data) is transmitted via a transmission channel, in radio communication systems this is done by means of electromagnetic waves via a radio interface. The electromagnetic waves are emitted here with carrier frequencies which lie in frequency bands predetermined for the respective system. In the GSM mobile radio communication system (Global System for Mobile Communications) the carrier frequency lies in the 900 MHz range. For future radio communication systems, such as UMTS (Universal Mobile ...
