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.
Claims14
A method of arranging exchange of signals between user terminals in a cellular communication system and at least one base station comprising a central unit and a plurality of remote units, comprising:
- exchanging at least one user signal with a corresponding user terminal simultaneously via at least two of said remote units;
- applying, at said at least two remote units, beam-forming weights that are calculated in the central unit;
- and
- in a different step, applying, at said at least two remote units, separate complex distributing weights, determined in the central unit, to said user signal exchanged with said at least one user terminal.
A distributed antenna system for exchanging signals with user terminals in a cellular communication system, comprising a central unit and a plurality of remote units, wherein said distributed antenna system is configured to:
- exchange at least one user signal with a corresponding user terminal simultaneously via at least two of said remote units;
- apply, at said at least two remote units, beam-forming weights that are calculated in the central unit;
- and
- in a different step, apply, at said at least two remote units, separate complex distributing weights, determined in the central unit, to said user signal exchanged with said at least one user terminal.
A non-transitory computer-readable medium storing a computer program product, loadable in a memory of at least one computer and comprising software code portions configured to perform the steps of:
- exchanging at least one user signal with a corresponding user terminal simultaneously via at least two remote units;
- applying, at said at least two remote units, beam-forming weights that are calculated in the central unit;
- and
- in a different step, applying, at said at least two remote units, separate complex distributing weights, determined in the central unit, to said user signal exchanged with said at least one user terminal.
