摘要： The invention relates to a radio system and a method of determining the transmission direction. The radio system comprises at least one base station (100) communicating with terminals (102-106) within its area by emitting a radiation pattern (110) extending over the whole cell area and directional radiation patterns (112-116) covering only part of the cell area. The base station transmits base-station-related information on a common control channel to the terminals. In the solution of the invention, the base-station-related information transmitted by the base station comprises a general part and a beam-specific part. The base station uses the radiation pattern (110) extending over the whole cell area when transmitting the general part. Each beam-specific part is transmitted by using a specific radiation pattern (112-116). The terminal detects one or more beam-specific parts from the information received from the base station and transmits information about the detection result to the base station, on the basis of which the base station decides which directional radiation pattern to use when communicating with the terminal. The invention enables fast determination of the terminal direction with respect to the base station.

摘要： The present invention relates to a base station, and a method for improving connection quality in a cellular radio system, which system comprises in each cell at least one base station (BS), which communicates with the subscriber terminal equipments (MS) located within its area, and which sends out transmissions by using at least one carrier frequency, and in which system the signal transmitted at each frequency is divided on the time division principle into a frame consisting of several time slots, and which base stations transmit information on themselves to the subscriber terminal equipments. To improve the quality of the connection between the base station and a subscriber terminal equipment, the antenna via which the signal intended for the terminal equipments of the base station is transmitted is changed on the time division principle in such a manner that the base station sends out transmissions via one antenna at a time for a certain predetermined period, after which the antenna to be used is changed.

摘要： The invention relates to an arrangement for attenuating electromagnetic interference propagating through a connector (11) in an electronic device positioned in a metal housing (1, 2). The inner space of the grounded metal housing (1, 2) is divided into at least three separate, substantially radiation-proof compartments (7, 9, 10) by metal partition walls (4, 6, 8) and/or metal foils (21) provided in a printed circuit board (3). The connector (11) is positioned in the first compartment (9) in the outer wall of the housing, and the electronic circuits which cause interference or are sensitive to it are substantially positioned in the third compartment (10). Each connection wire (13a, 13b, 13c) from the connector passes into the second compartment (7) from the first compartment through a respective first wire hole (18) provided in the grounded metal foil (21) of the printed circuit board (3), and then into the third compartment (10) from the second compartment through a respective second wire hole (19) provided in the grounded metal foil (21) of the printed circuit board (3).
