Abstract (en)

[origin: WO9922475A2] The invention relates to a radiocommunications system constructed by radio cells in which realized data channels are distinguishable in a radio cell by expansion codes assigned to said data channels. A set of expansion codes is assigned to specific combined radio cells, whereby the set of expansion codes differentiates (code-reuse) itself from the sets of expansion codes which are utilized by adjacent combined radio cells. The radiocommunications system is especially suited for use in third generation TD/CDMA mobile radio networks.
