Abstract
In a cellular radio system data is transmitted to a Dual Carrier mobile station from two different cells during a data transfer. Hereby existing hardware in a GSM system can be utilized more efficiently. The data transmission from the two cells can be frame synchronized. Frame synchronization can for example be obtained by transmitting data from two cells located on the same radio base station site.

A Global System for Mobile telephony (GSM) system for transmitting downlink data to a mobile station simultaneously on two different carriers, said system comprising:
- a first radio transmitter in a first cell transmitting on a first one of the two different carriers;
- and
- a second radio transmitter in a second cell transmitting on a second one of the two different carriers;
- said first and second transmitters configured to simultaneously transmit the downlink data to the mobile station on the first and second carriers.
A method of transmitting downlink data to a mobile station simultaneously on two different carriers in a Global System for Mobile telephony (GSM) system, the method comprising configuring first and second transmitters transmitting on two different carriers from two different cells to transmit the downlink data to the mobile station in a dual link transmission, and simultaneously transmitting the downlink data on the two different carriers.
