Abstract (en)

[origin: WO9912284A1] The present invention relates to methods for assigning spreading codes to forward-link connections with variable bit-rate in DS-CDMA communication systems. A first connection is assigned a first number of codes (x) from a first set (S1) of orthogonal codes. A second connection is assigned a second number of codes (y). A first part (y-k1) of the second number of codes (y) is taken from the first set (S1) of orthogonal codes. A second part (k1) of the second number of codes (y) is taken from a second set (S2) of orthogonal codes which is non-orthogonal to the first set (S1).
