10.7.0 General

Hybrid Cells have a CSG Indication bit set to FALSE but broadcast a CSG Identity and the PCI values for hybrid cells are not contained within the reserved PCI range for CSG cells. Similar to CSG cells, the network can reserve a PCI list for hybrid cells.

The network shall distinguish whether it is a hybrid cell, e.g. by reserving a PCI list for hybrid cells.

10.7.1 RRC_IDLE

When the CSG ID and associated PLMN ID of the hybrid cell belong to the Permitted CSG list of the UE, the hybrid cell is considered by the UE as a CSG cell in idle mode cell selection/reselection procedures.

NOTE: The autonomous search for hybrid cells does not imply that a UE needs to constantly check the CSG ID and associated PLMN ID of all cells it sees.

For all other UEs, normal cell selection/reselection procedures apply with hybrid cells (as for non CSG cells).

Manual selection of CSG IDs of hybrid cells is also supported in the same way as for CSG cells.

10.7.2 RRC_CONNECTED

10.7.2.1 Inbound Mobility

Inbound mobility to hybrid cells is described in clause 10.5.1.2.

10.7.2.2 Outbound Mobility

Procedure for outbound mobility from CSG cells applies (See clause 10.5.2.2).
