A method and a wireless transmit/receive unit (WTRU), including a universal subscriber identity module (USIM), for identifying, detecting and accessing a closed subscriber group (CSG) cell are disclosed. The WTRU receives a broadcast from a cell including a cell identifier (ID). If the cell ID is associated with a CSG cell, the WTRU determines whether the CSG ID is programmed in the USIM. The cell broadcast may include a single bit information element (IE) indicating that the cell is a CSG cell. The cell broadcast may further include a bit indicating whether the CSG cell is public or private. Different detection and access methods are also provided for detecting public and private CSG cells. Mobility detection methods for the WTRU in the CSG cell are also provided.
