    摘要: A method system and components for outer loop power control particularly useful for non-real time/real time data services uses data transmitted in many bursts of short duration, called Temp-DCH allocations. A target metric, preferably, target SIR, is adjusted with differing step up and step down levels to converge on a relatively low steady state level of step up and step down target metric adjustments. The initial target SIR and the transient step size for target SIR adjustment is determined in a dynamic way in the outer loop power control for each Temp-DCH allocation of non-real time data.

    摘要: A method and apparatus for sending a channel quality indication (CQI) via a shared channel while a wireless transmit/receive unit (WTRU) is in a Cell_FACH state without having a dedicated channel allocated for the WTRU are disclosed. A WTRU performs a measurement of at least one parameter and generates a CQI based on the measurement. The WTRU then transmits the CQI via a random access channel (RACH). The CQI may be transmitted using an RACH preamble. A plurality of signature sequences may be divided into a plurality of groups. The WTRU may select one group based on the CQI and randomly select a signature sequence among signature sequences in the selected group for transmitting the RACH preamble. The CQI may be appended to the RACH preamble. The CQI may be transmitted via a control part or a data part of the RACH message.

    摘要: A method and apparatus for reducing transient impacts of beam switching in a switched beam antenna system are disclosed. A switch beam antenna system generates a plurality of beams in a predefined beam pattern and switches the current beam position to one of the plurality of predefined beams in accordance with measurement results for each of the beams. Quality of signals is periodically measured for each of the plurality of predefined beams, and the best beam is determined. The current beam is switched to either the best beam or an intermediate beam in accordance with the separation between the best beam and the current beam.
