FIELD: information technologies.
SUBSTANCE: wireless transfer-reception unit (WTRU) does a measurement of at least one parameter and generates CQI on the basis of the measurement. WTRU then sends CQI via a random access channel (RACH). CQI may be transferred using a RACH preamble. Multiple signature sequences may be divided into multiple groups. WTRU may select one group on the basis of CQI and may randomly select a signature sequence among signature sequences in the selected group for transfer of RACH preamble. CQI may be added to a RACH preamble. CQI may be sent via a control part or a data part of a RACH message.
EFFECT: possibility to send indication of channel quality via a multiplex channel, when a wireless transfer-reception unit is in Cell_FACH condition.
