    • 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.

    • The invention relates to a method for transmitting packet data in a radio system, the radio system comprising at least one base station and at least one subscriber terminal and a downlink power control arrangement, in which power control arrangement the quality of a signal transmitted by the base station is evaluated and, on the basis of this evaluation, power control commands are transmitted to the base station. The method comprises analysing (302) the power control commands received by the base station, searching (304) for one or more transmission moments, on the basis of the analysis, that satisfy the set conditions for packet-switched data transmission, and if at least one transmission moment is found that satisfies the set conditions, transmitting (306) packet data to at least one subscriber terminal at least at one transmission moment that satisfies the set conditions.
