Method of allocating communication codes to channels set up in respect of
mobile terminals in communication in a cell of a radiocommunication
system, in which the cell is served by a fixed station having means of
adjustment of 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 some at least
of which are mutually orthogonal. In response to channel setup or
reconfiguration request in respect of a first mobile terminal in the
cell, the allocation to the said channel of a code nonorthogonal to at
least one code of the set already allocated to another channel set up in
respect of a second mobile terminal in the cell is conditionally
admitted, as a function of a comparison between the send/receive
parameters determined in respect of the first and second terminals.
