ABSTRACT:
There is disclosed a method of allocating a channelisation code comprising, for each user, defining a path in the code tree based on a required range of spreading factors, selecting a node of the path in dependence on the currently required spreading factor; and reserving all nodes on the code tree in an upward and downward direction from the selected node, wherein the selected node for any user must not coincide with a node reserved by any other user.
