<p>Provided is a method of decoding channelisation code set information to determine the number of channelisation codes and the code offset in a spread spectrum data transmission, where the channelisation code set information includes a first group of bits encoding the number of channelisation codes and a second group of bits encoding the code offset, the method includes deriving the number P of channelisation codes according to P = C + ⌊ m - A n ⌋ , and deriving the code offset O according to O = ⌊ P n ⌋ x ( m - 2 B ) + ( B + 1 ) ; where m is the maximum number of multicodes allocated from the spread spectrum data transmission, n = ⌊ m 2 ⌋ + 1 , A is the value of the first group of bits of the channelization code set information, B is the value of the second group of bits of the channelisation code set information, and C = A + ⌊ B m - A ⌋ x ( m - 2 A ) .</p> |
