Abstract: A method of directional radio communication in a mobile communication network between a first station (4) and a second mobile station (MS) comprises the following steps. Communication data transmitted by a second station (MS) is received at the first station (4). The communication data can travel via one or more of a plurality of signal paths and is received as a set of signals from one or more of a plurality of different beam directions. A first beam direction corresponding to the beam direction from which a first one of the signals is received by the first station representing a shortest one of the signal paths is determined as is a second beam direction corresponding to the beam direction from which one of the signals having the greatest signal strength is received. Where the first and second beam directions are different, communication data is transmitted from the first station (4) to the second station (MS) in both the first and second beam directions.

Abstract: The invention relates to a method of improving the quality of a radio connection (170) in a cellular radio network. Relevant for the invention, the cellular radio network includes a base station system (126) and a subscriber terminal (150). A bidirectional radio connection (170) using a directional antenna beam (304) is provided between the base station system (126) and the subscriber terminal (150). In the method, in the base station system (126) an angle of incidence (302) of the directional antenna beam (304) is formed on the basis of a received radio signal (170A) transmitted by the subscriber terminal (150). The base station system (126) transmits a radio signal (170B) to the subscriber terminal (150) in the direction of an angle of departure (308) formed on the basis of the angle of incidence (302). In accordance with the invention, a ratio is formed for the imbalance between the downlink and uplink traffics.

Abstract: A method of directional radio communication and mobile communication network between a first station and a second mobile consists of the following steps. Consecutive bursts of communication data transmitted from the second station are identified at the first station. Respective beam directions from which sequential communication data bursts are received by the first station are determined from a plurality of adjacent beam directions. One or more of the beam directions are selected for transmission of signals from the first station to the second station so that when it is determined that the sequential communication data bursts are received by the first station from two different beam directions, the two different beam directions are simultaneously selected for transmission of the signal from the first station to the second station.

Abstract: The invention relates to a method of improving the quality of a radio connection (170) in a cellular radio network. Relevant for the invention, the cellular radio network includes a base station system (126) and a subscriber terminal (150).
