Abstract
A method and apparatus for performing a serving high speed downlink shared channel (HS-DSCH) cell change from a source cell to a target cell are disclosed. A wireless transmit/receive unit (WTRU) may be pre-configured with HS-DSCH configuration for the target cell. The WTRU may start monitoring a high speed shared control channel (HS-SCCH) on the target cell using the pre-loaded HS-DSCH configuration for the target cell on a condition that a measurement report is triggered by the event 1D. The WTRU may initiate a timer when the WTRU starts monitoring the HS-SCCH on the target cell.
Claims26
A wireless transmit/receive unit (WTRU), the WTRU comprising:
- circuitry configured to send a measurement report for an event 1A, wherein the event 1A occurs when a new cell for potential addition to an active set is identified;
- circuitry configured to receive and store target cell pre-configuration information;
- circuitry configured to send a measurement report for an event 1D, wherein the event 1D occurs when there is a change of best cell;
- circuitry configured to start a timer;
- circuitry configured to monitor a high speed shared control channel (HS-SCCH) of a target cell until expiry of the timer;
- and
- wherein the target cell pre-configuration information is used on the target cell.
A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
- sending, by the WTRU, a measurement report for an event 1A, wherein the event 1A occurs when a new cell for potential addition to an active set is identified;
- receiving and storing, by the WTRU, target cell pre-configuration information;
- sending, by the WTRU, a measurement report for an event 1D, wherein the event 1D occurs when there is a change of best cell;
- starting, by the WTRU, a timer;
- monitoring, by the WTRU, a high speed shared control channel (HS-SCCH) of a target cell until expiry of the timer;
- and
- wherein the target cell pre-configuration information is used on the target cell.
