Abstract
A method and apparatus are provided that allow a wireless transmit/receive unit (WTRU) to search and add one or more closed subscriber group (CSG) identities (IDs) in the WTRU white list while in connected mode. Such method and apparatus include but are not limited to WTRU autonomous search or a manual search WTRU initiated procedures or network initiated procedures. Additionally methods that allow the network and/or the non-access stratum (NAS) to add CSG IDs are also described.

Claim
1. A wireless transmit/receive unit (WTRU) comprising:
a transmitter configured to transmit a first measurement report including a physical layer cell identity (PCI) of a potential closed subscriber group (CSG) cell to an eNodeB;
a receiver configured to, in response to the transmitted first measurement report, receive a message from the eNodeB indicating that the WTRU is to acquire system information (SI) of the potential CSG cell; and
at least one processor configured to read information from the aquired SI,
wherein the transmitter is further configured to, in response to the received message from the eNodeB, transmit a second measurement report for the potential CSG cell including the information read from the acquired SI.
2. The WTRU of claim 1, wherein the receiver is configured to detect the potential CSG cell in an autonomous search and the autonomous search includes a scan of all frequencies in supported bands.
3. The WTRU of claim 1, wherein the receiver is configured to detect the potential CSG cell in an autonomous search and the autonomous search includes a scan of CSG dedicated frequencies.
4. The WTRU of claim 1, wherein the receiver is configured to detect the potential CSG cell in an autonomous search and the autonomous search includes a scan of frequencies provided to the WTRU.
5. The WTRU of claim 1, wherein the transmitter is configured to indicate to the eNodeB that the PCI is an unvisited PCI.
6. The WTRU of claim 1, wherein the acquired SI is for a highest ranked CSG cell.
7. The WTRU of claim 1, wherein the acquired SI is for a best quality CSG cell.
8. A method for use in a WTRU, the method comprising:
transmitting, by the WTRU, a first measurement report to an eNodeB, wherein the first measurement report includes a physical layer cell identity (PCI) of a potential closed subscriber group (CSG) cell;
in response to the transmitted first measurement report, receiving, by the WTRU, a message from the eNodeB that indicates that the WTRU is to acquire system information (SI) of the potential CSG cell; and
in response to the received message, acquiring the SI of the potential CSG cell and transmitting a second measurement report for the potential CSG cell including information read from the acquired SI.
9. The method of claim 8, further comprising detecting the potential CSG cell in an autonomous search that includes scanning of all frequencies in supported bands.
10. The method of claim 9, further comprising detecting the potential CSG cell in an autonomous search that includes scanning of CSG dedicated frequencies.
11. The method of claim 9, further comprising detecting the potential CSG cell in an autonomous search that includes scanning of frequencies provided to the WTRU.
12. The method of claim 9, further comprising indicating to the eNodeB that the PCI is an unvisited PCI.
13. The method of claim 9, wherein the acquired SI is for a highest ranked CSG cell.
14. The method of claim 9, wherein the acquired SI is for a best quality CSG cell.
