FIELD: physics, communications.
SUBSTANCE: disclosed is a method and system for providing control information for supporting high-speed packet access downwards and high-speed packet access upwards. Unit B assigns at least one control downward channel and at least one upward channel for controlling the wireless transmission/reception unit (WTRU). The control downward channel and the control upward channel are provided for transmitting control information and for the downlink and uplink. Traditional control channels for the downward and upward directions are combined into a smaller set of control channels for the uplink and downlink. Unit B and the WTRU exchange control information over the control downward channel and the control upward channel. WTRU receives downlink data and transmits uplink data, and unit B receives uplink data and transmits downlink data based on control information transmitted over the downward control channel and the upward control channel.
EFFECT: efficient support for high-speed downlink and uplink.
