Abstract:
1. A method for allocating communication codes to channels set up in respect of mobile terminals communicating in a cell of a radiocommunication system, in which the cell is served by a fixed station having means for adjusting send/receive parameters defining a respective antenna pattern in respect of each mobile terminal in the cell, in which the allocated communication codes form part of a set of codes, a plurality of which are mutually orthogonal, said method comprising: in response to a channel setup or reconfiguration request for a first mobile terminal in the cell, allocating a code to the channel; wherein the allocation to the channel of a code that is nonorthogonal to at least one code of the set that is already allocated to another channel set up in respect of a second mobile terminal in the cell is conditioned on at least a comparison between the send/receive parameters determined in respect of the first and second terminals.
