Embodiment Construction

[0020] Since second generation (2G) and third generation (3G) radio systems and their different combinations, the so-called 2.5 generation radio systems, are used and continue to develop worldwide, in figure 1 Embodiments are described in a represented radio system comprising different generations of network elements side by side. In the description, the 2G radio system is represented by GSM (Global System for Mobile Communications) and the 3G radio system is represented by a radio system based on GSM and utilizing EDGE (Enhanced Data Rates for Global Evolution) technology to increase data transmission speed This means that the radio system can also be used for packet transmission in the GPRS system (General Packet Radio System), which stands for the 2.5G radio system. 3G systems are also represented by systems known at least by the names IMT 2000 (International Mobile Telecommunications 2000) and UMTS (Universal Mobile Telecommunications System). However, the embodiments are...

Abstract

The invention relates to a method of controlling a radio system in a base transceiver station (204), in which base transceiver station (204) at least one antenna array is formed, which comprises at least two antennas (236, 238) for transmitting and receiving a signal, and in which method at least two antennas (236, 238) of each antenna array are arranged in such a way that antenna beams (410, 412) formed by the at least two antennas deviate vertically from each other what it comes to at least one property thereof. The antenna array can be controlled in a desired manner by controlling the ratio of the signal powers supplied to each antenna of the antenna array. The solution of the invention provides for instance flexibility for controlling signal power, which reduces interference in a radio system and increases data transmission capacity in a radio system.

Description

technical field [0001] The invention relates to a method of controlling transmissions in a radio system and a device for implementing the method, said device comprising at least one base transceiver station connected to terminals in its area. Background technique [0002] The invention can be applied in any radio system, in particular a cellular radio system using Wideband Code Division Multiple Access, WCDMA. [0003] In the WCDMA method, a narrowband data signal is multiplied with a spreading code which is significantly wider than the bandwidth of the data signal, so that the information in the data signal is distributed over the entire frequency band being used. All terminals and the base transceiver station transmit simultaneously to the same frequency band, and a connection is established between each terminal and the base transceiver station by using a separate spreading code for each terminal. The data signal is returned at the receiver to the original frequency band...
