It is provided a method, including coupling respective portions of a transmission resource to fixed beams in a 1:1 relationship such that the portions coupled to different fixed beams do not overlap, wherein the transmission resource is foreseen for transmission by the cell, each of the fixed beams is defined by a fixed beam weight vector, and a number of the fixed beams is predefined and equal to or larger than 2; allocating one of the fixed beams and the portion of the transmission resource coupled to the one of the fixed beams to a terminal; configuring a transmitting device to transmit to the terminal in the fixed beam and the portion of the transmission resource allocated to the terminal.

Time- and/or frequency-domain coordinated scheduling and beamforming

A training sequence is pre-filtered in a radiocommunication system having an emitter in the form of an antenna device with several antenna systems, thereby making it possible to transmit the training sequences through a pre-filter to said antenna systems side for reradiation by the emitter. Estimation enabling to form the properties of radio transmission channels described by spatial correlations is formed. The prefilter is dimensioned according to the correlations, thereby minimizing the error value of an algorithm used for estimation the channel on a reception side.

A method forms polar diagrams in a connection between a subscriber and a base station with an antenna arrangement in a radio communications system using multiple access methods. Antenna signals are associated with polar diagrams of the antenna arrangement by a common beam forming network. The common beam forming network is used to form weighted sum signals, which are passed as input signals to a user-specific beam forming unit. A selector which is arranged there takes from the input signals a user-specific subset Kc of signals, to which an eigen polar diagram forming algorithm is applied.

In a method for indoor operation of a wireless telecommunication device that comprises at least one base station and at least one mobile part, the momentary reception power is measured in the receiver of the mobile part and the reception power value is communicated to the base station for the control of the transmission power. The ratio of reception power to noise power is determined at predetermined time intervals in the receiver of the mobile part. The respectively obtained ratio value is compared to a rated value and, dependent on the result, one signalling bit per data frame is transmitted from the mobile part to the base station. A calculation of the current or updated transmission power with adaptive incrementation control is then undertaken in the base station. The calculation of a current transmission power value thereby occurs on the basis of the previous transmission power value plus a product of a correction value determining the incrementation and a default value determined from the signalling bit.
