Embodiment Construction

[0052] Figure 1 shows a schematic diagram of the architecture of a radio base station (BTS or Node B) in a mobile radio network (not shown in its entirety). In particular, consider a radio base station 10, which has an optical-to-digital interface, with three data streams in the downlink and thus also three data streams in the uplink.

[0053] A radio base station 10, which may be in the form of a conventional BTS, comprises a subsystem 10a, handling the transmission of signals in the downlink of the three data streams, and a subsystem 10b, comprising equipment dedicated to the reception of signals in the uplink .

[0054] T 1 Represents the first data stream of the three data streams in the downlink, T 2 Represents the first of the three data streams in the uplink. In the example considered, each data stream is routed to the fiber optic rings 15a and 15b by means of an optical transmitter in the downlink case and an optical receiver in the uplink case. Data streams may be...

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.

Description

technical field [0001] The invention relates to the technology of radio access in mobile radio networks. [0002] The invention has been developed with particular attention to its possible use in networks employing distributed radio base stations. Background technique [0003] Mobile radio systems have to guarantee communication services between a telecommunication network and mobile terminals (subscriber terminals) randomly distributed in a certain service area. Radio coverage of the area is obtained by installing a number of radio base stations, each with the task of covering a certain part of the area - called a cell - from which the name "cellular system" derives . A normal mobile terminal can communicate with the telecommunication network via one of the radio base stations of the system, eg the one from which it receives the best quality radio signal. The process by which a terminal selects a radio base station from which to receive system information after being tur...
