Claim Text:
1. A method for enabling mobility of a wireless transmit/receive unit (WTRU) in a cell forward access channel (CELL_FACH) state, the method comprising: receiving high speed downlink shared channel (HS-DSCH) traffic from a source cell configured for a first frequency; receiving, from a network node, a forward access channel (FACH) measurement occasion or a discontinuous reception (DRX) length for performing measurement on target cells; receiving, from the network node, an extended FACH measurement occasion or an extended DRX length for performing inter-frequency measurements on closed subscriber group (CSG) target cells or hybrid target cells, wherein the extended FACH measurement occasion or the extended DRX length for performing the inter-frequency measurements on the CSG target cells or the hybrid target cells is greater than the FACH measurement occasion or the DRX length for performing the measurements on the target cells; determining, at the WTRU, whether the WTRU is within a proximity to a CSG target cell or a hybrid target cell configured for a second frequency while in the CELL_FACH state; when the WTRU is determined to be within the proximity to the CSG target cell or the hybrid target cell configured for the second frequency while in the CELL_FACH state, stopping receipt of the HS-DSCH traffic from the source cell for a period of the extended FACH measurement occasion or the extended DRX length to perform the inter-frequency measurements on the CSG target cell or the hybrid target cell to determine whether to perform reselection; and when the WTRU is determined to be within a proximity to a target cell, stopping receipt of the HS-DSCH traffic from the source cell for a period of the FACH measurement occasion or the DRX length to perform the measurements on the target cell to determine whether to perform reselection.
