FIELD: radio engineering, communication.
SUBSTANCE: disclosed is initiating and operating a high-speed dedicated physical control channel, HS-DPCCH, to report a current channel quality indicator, CQI. User equipment, UE, may receive a high speed-shared control channel, HS-SCCH, command 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 command, 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).
EFFECT: improved user interaction with mobile communication systems as requirements for mobile broadband access increase.
