12.57 PCID Group

The PCID Group information element contains the description of a group of one or more physical layer cell identities for E-UTRAN cells (see 3GPP TS 36.211).

Table 12.57.2: PCID Group information element details

PCID (9 bit field)
This field specifies the physical layer cell identity of a single E-UTRAN cell.

PCID_BITMAP_GROUP (6 bit field)
Each bit number n, where n can take the value from 1 to 6, represents the group of PCID values in the range (n-1) * 84 to (n*84)-1 inclusive.

When this field is received as part of the Not Allowed Cells IE, if bit number n is set to ‘1’, then all cells whose PCID belongs to the group identified by that bit are not allowed; correspondingly, if bit number n is set to ‘0’, then all cells whose PCID belongs to that group are allowed.

When this field is received as part of the CSG_PCI_SPLIT IE, if bit number n is set to ‘1’, then all cells whose PCID belongs to the group identified by that bit are part of the CSG; correspondingly, if bit number n is set to ‘0’, then all cells whose PCID belongs to that group are not part of the CSG.

When this field is received as part of the PCID to TA mapping IE, if bit number n is set to ‘1’, then all cells whose PCID belongs to the group identified by that bit are part of the same TA, correspondingly, if bit number n is set to ‘0’, then all cells whose PCID belongs to that group are not part of the same TA.

PCID_Pattern_length (3 bit field)
PCID_Pattern
PCID_pattern_sense (1 bit field)
If the PCID_pattern_sense bit is equal to ‘0’ then the group of identified cells are those where the most significant bits of the physical layer cell identity are equal to "PCID_pattern". If the PCID_pattern_sense bit is equal to ‘1’ then the group of identified cells is all those where the most significant bits of the physical layer cell identity are not equal to the PCID_pattern.
