Method and apparatus for identifying and reporting non-operational enhanced uplink signaling channels


Abstract
A method and apparatus for identifying and reporting a non-operational enhanced uplink (EU) signaling channel. A wireless transmit/receive unit (WTRU) sends a channel allocation request for an enhanced dedicated channel (E-DCH) to a Node-B through an uplink (UL) EU signaling channel. In response to the request, the Node-B sends channel allocation information to the WTRU through one or more downlink (DL) EU signaling channels. If the WTRU does not receive the channel allocation information before a predetermined time period established by a request response timer expires, the WTRU reports a non-operational EU signaling channel to a radio network controller (RNC) via the Node-B. The Node-B reports a non-operational EU signaling channel when the Node-B does not receive E-DCH data transmissions after sending the channel allocation information, or receives subsequent E-DCH data transmissions which are inconsistent with the channel allocation information.
