    Abstract: A wireless tramsmit receive unit (WTRU) and a method provide controlled transmitter power in a wireless communication system in which both dedicated and shared channels are utilized. A network unit preferably has a receiver for receiving UL user data from WTRUs on uplink dedicated channels, UL DCHs, and at least one uplink shared channel, UL SCH, and a processor for computing target metrics for UL DCHs based on the reception of signals transmitted by a WTRU on an UL DCH associated with an UL SCH usable by the WTRU. A shared channel target metric generator is provided that is configured to output a respective UL SCH target metric derived from each computed UL DCH target metric. Each WTRU preferably has a processor which is configured to compute UL DCH power adjustments for an UL DCH associated with an UL SCH as a function of UL DCH target metrics computed by the network unit based on the reception of signals transmitted by the WTRU on the UL DCH and UL SCH power adjustments for the associated UL SCH as a function of the respective UL SCH target metrics output from the shared channel target metric generator. Preferably, the target metrics are target signal to interference ratios (SIRs).

    Abstract: Method and apparatus for synchronizing base employing an independent synchronizing source or identifying a base station as a master source. An RNC (C-RNC) or a base station may designate one base station or a UE to acquire measurements derived from base stations to achieve synchronization. Synchronization activities may be regularly scheduled or may be undertaken when periodic measurements indicate that a drift value exceeds a given threshold.

    Abstract: A method and apparatus for minimizing redundant enhanced uplink (EU) allocation requests and fault-tolerating EU transmission failures that occur between a wireless transmit/receive unit (WTRU) (102) and a Node-B (104). The WTRU (102) transmits an enhanced dedicated channel (E-DCH) allocation request to the Node-B (104) over an uplink (UL) EU channel (110). In one embodiment, if E-DCH allocation cannot be provided within a predetermined time period, the Node-B sends an acknowledgement message to the WTRU via a downlink (DL) EU signaling channel (112) without sending E-DCH allocation information. The request is queued in the Node-B and the WTRU refrains from transmitting the same request until after the time period expires or resources become available. In another embodiment, appropriate actions are taken to correct EU transmission failures by determining whether an E-DCH allocation request was unsuccessfully delivered via the UL EU channel or whether channel allocation information was unsuccessfully delivered via the DL EU signaling channel.

    Abstract: In a wireless communication system including a wireless transmit/receive unit (WTRU) and at least one Node-B, a method and apparatus is used to selectively enable reception of at least one downlink (DL) enhanced uplink (EU) signaling channel established between the WTRU and the Node-B(s). During the operation of an enhanced dedicated channel (E-DCH), the WTRU monitors at least one DL EU signaling channel established between the WTRU and the Node-B(s) only when it is necessary, based on the WTRU's knowledge of at least one established standard procedure. The WTRU coordinates and consolidates DL signaling channel reception requirements of a plurality of channel allocation and/or data transmission procedures carried out by the WTRU in accordance with the established standard procedure. The WTRU determines whether to enable reception of at least one specific DL signaling channel based on the consolidated DL signaling channel reception requirements.
