Abstract: A method is proposed of arranging, in a mobile communication network, transmission of data between user equipment and at least one base station including a central unit and at least one remote unit associated therewith. The method includes at a transmitting side including the remote unit or the central unit, quantizing the data according to a quantization bit number, and transmitting, over a fronthaul link between the transmitting side and a receiving side including the central unit or the remote unit, respectively, the quantized data to the receiving side. The method further includes, at the central unit: determining the quantization bit number, wherein the determining including varying in time the quantization bit number according to network information available at the central unit, and communicating to the at least one remote unit the determined quantization bit number.

Abstract: A method is proposed of arranging, in a mobile communication network, transmission of data between user equipment and a base station including a central unit and at least one remote unit associated therewith. The data includes information data and, associated with the information data, first control data substantially time-varying over a scheduling time period, and second control data substantially time-unvarying over the scheduling time period. The method includes at the central unit side, transmitting the information data and the first control data to the at least one remote unit, and at the at least one selected remote unit side, receiving the information data and the first control data from the central unit, generating the second control data, combining the generated second control data with the received information and first control data into the data, and transmitting the data to a selected user equipment.

Abstract: A method of arranging exchange of signals between user terminals in a cellular communication system and at least one base station. The base station includes a central unit and a plurality of remote units. The signals are exchanged between the central unit and the remote units as aggregated signals for plural user terminals. The signals are processed at the remote units as distinct signals each associated with a respective one of the plural user terminals.

Abstract: A method arranges, in a mobile communication network, data transmission between user equipment and at least one base station including a central unit and at least one remote unit associated therewith. The data includes information data and control data from the central unit to the remote unit, or vice versa. The method includes allocating radio resources for the data to/from the remote unit, grouping the allocated radio resources, each group including at least one radio resource allocated for data to/from a respective remote unit, including in each group data indicating an association of the allocated radio resource of that group with the respective remote unit, including in each group allocation data indicating the allocated radio resources, among the at least one allocated radio resource, that have been allocated for the information data, and transmitting the groups in the frequency-domain between the central unit and the at least one remote unit.

Abstract: A method of arranging exchange of signals between user terminals in a cellular communication system and at least one base station including a central unit and a plurality of remote units. The method includes exchanging signals with at least one user terminal simultaneously via at least two remote units by applying at the at least two remote units, separate distributing weighting functions to the signals exchanged with the at least one user terminal.

Abstract: Communications method between a main station and processing nodes includes interconnecting the main station and the nodes in an optical path defining adjacent nodes and non-adjacent nodes, operatively grouping the nodes in a plurality of distinct sub-groups, each formed by non-adjacent nodes, at least one of said sub-groups including at least two nodes generating at the main station a multiplexed optical signal propagating along the path for serving the nodes, the multiplexed optical signal including a plurality of optical channel signals having a respective plurality of distinct carrier wavelengths, each carrier wavelength being associated with a respective sub-group of nodes, and serving each node of each sub-group of nodes with a respective portion of the optical channel signal having the associated carrier wavelength.

Abstract: A radio base station for a mobile radio network, includes a set of remote units connected with the radio base station, preferably via a radio over fibre arrangement. Each remote unit provides radio cell coverage by means of a set of communication channels, and is equipped with a respective set of antenna elements. The communication channels are distributed over the antenna elements according to an assignment scheme that is dynamically variable.
