Scrambling code planning is usually associated with assigning a downlink primary scrambling code to each cell. It can also be associated with assigning groups of uplink scrambling codes to each RNC. The resultant uplink and downlink scrambling code plans form part of the RNC databuild.
3GPP TS 25.213 specifies 512 downlink primary scrambling codes. Each primary scrambling code has 15 secondary scrambling codes. Each primary and each secondary scrambling code has a left alternative scrambling code and a right alternative scrambling code. Secondary scrambling codes may be used for beamforming whereas left and right alternative scrambling codes may be used by SF/2 compressed mode.
