SUPPORTING DOWNLINK DL TRIGGERED CQI FEEDBACK ON THE HS DPCCH CHANNEL IN A CELL IN CELL_FACH STATE

摘要

Initiating and operating a high speed dedicated physical control channel HS DPCCH to report a current channel quality indicator CQI. A user equipment UE may receive a high speed sharedcontrol channel HS SCCH order from a Node B triggering a feedback response (i.e. a feedback regarding CQI and/or ACK/NACK on the HS DPCCH channel). The UE may perform a physical random access channel (PRACH) procedure in response to receiving the order and may also initiate a collision resolution procedure. The user equipment may transmit a current channel quality indicator (CQI) of the user equipment on a high speed dedicated physical control channel (HS DPCCH) prior (before beforehand) to achieving collision resolution (i.e. a result from the collision resolution procedure).
