MÉTODO E APARELHO DE ENVIO DE INDICAÇÃO DE QUALIDADE DE CANAL POR MEIO DE UM CANAL COMPARTILHADO |
摘要 |
A method and apparatus for sending a CQI via a shared or common channel while a 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 an 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. The RACH message may be an RRC measurement report including CQI transmission. The CQI reporting may be triggered by successful decoding of the HS-SCCH transmission. |
