Patent ID: 7548528

Claim:
A method for assigning codes for data transmissions between a radio station and at least one subscriber station over a wireless interface of a radio communication system, where M codes are available for assignment and each of the M codes corresponds to a branch at a same level in a code tree, so that a first half of M branches originates from a first parent branch and a second half of the M branches originates from a second parent branch, comprising: assigning in network-side equipment in the radio station N codes taken from the M codes in such a way that N branches corresponding to the N codes in the representation at the same level lie contiguously adjacent to one another, where N is at least two and M is at least two multiplied by N and, of the N branches corresponding to the N codes in the representation at the same level, an equal number of the N branches originate from each of the first and second parent branches if N is an even number, while (N−1)/2 branches originate from the first parent branch and (N+1)/2 branches originate from the second parent branch if N is an odd number.
