The PSC Group information element contains the description of a group of one or more primary scrambling codes for UTRAN FDD cells (see 3GPP TS 25.213) or a group of one or more cell parameters for UTRAN TDD cells (see 3GPP TS 25.223).

Table 12.58.2: PSC Group information element details

PSC (9 bit field)
This field specifies the primary scrambling code of a single FDD cell or the cell parameter of a single TDD cell. For TDD cells, the Cell Parameter is contained in the 7 least significant bits of the field; the 2 most significant bits are ignored.

PSC_Pattern_length (3 bit field)
PSC_Pattern
PSC_pattern_sense (1 bit field)
If the PSC_pattern_sense bit is equal to ‘0’ then the group of identified codes are those where the most significant bits of the primary scrambling code or the cell parameter are equal to "PSC_pattern". If the PSC_pattern_sense bit is equal to ‘1’ then the group of identified codes is all those where the most significant bits of the primary scrambling code or cell parameter are not equal to the PSC_pattern. For TDD frequencies, if the pattern contains more than 6 bits only the most significant 6 bits shall be used.
