Methods and apparatus are disclosed for a wireless transmit/receive unit (WTRU) to detect and perform measurements with respect to Home Node-Bs (HNB) and Home evolved Node-Bs (H(e)NB) (collectively “HNB”). The methods may include generating and transmitting a request for a measurement configuration that may include gap allocations to detect and measure a primary scrambling code or a physical cell identity of a target HNB for at least one frequency or radio access technology (RAT). The request may be in response to the WTRU entering a HNB cell for which the WTRU has stored fingerprint information and whose closed subscriber group ID is in the WTRU's whitelist. The network may configure the WTRU to measure the requested frequency or RAT in response to the proximity report/request. Methods are described for releasing the measurement configuration.
