Abstract: A method and an apparatus for utilizing multiple carriers are disclosed. A wireless transmit/receive unit (WTRU) capable of receiving on a single downlink carrier at a time may tune the receiver to one downlink carrier and switch the downlink carrier in accordance with a configured pattern. The WTRU may switch the carrier from an anchor carrier to a non-anchor carrier at a high speed shared control channel (HS-SCCH) sub-frame boundary, and switches back at an end of a subsequent high speed physical downlink shared channel (HS-PDSCH) subframe. The WTRU may switch the carrier at an HS-PDSCH sub-frame boundary. A WTRU capable of receiving on multiple downlink carriers simultaneously may tune the receiver to an anchor carrier and a supplementary carrier, and switch the supplementary carrier to another carrier based on a carrier switching order. The carrier switching order may be received via an HS-SCCH or via layer 2 signaling.

Abstract: A wireless transmit/receive unit (WTRU) may operate in a first state where the WTRU does not have configured physical channels and discontinuously monitors for pages and a second state where the WTRU has configured uplink physical channels. The WTRU may, in response to a signal, transition to the first state and store an identity and medium access control (MAC) information. The WTRU may reinitiate communication with a network using the stored identity and MAC information.

Abstract: A first message may be received on a first carrier and communication initiated using a second carrier based on the received first message. Communication may continue on the first carrier such that the first carrier and the second carrier have different radio network terminal identifiers (RNTIs) and the first and second carrier have discontinuous reception cycles with different times of discontinuous reception. The discontinuous reception of the first carrier may be ceased based on a second message and the discontinuous reception of the second carrier may be ceased based on the third message.

Abstract: Techniques for transmit power control for multiple antenna transmissions in an uplink are disclosed. A wireless transmit/receive unit (WTRU) generates at least one input stream for transmission and applies a gain factor to each channel. The gain factor is determined based on a reference channel power estimate. The WTRU generates at least two data streams from the input stream for transmission via a plurality of antennas and applies weights to the data streams. The gain factor and/or the weights are controlled such that a transmit power on each antenna is within a maximum allowed value. The WTRU may perform power scaling on a condition that a transmit power on any antenna exceeds the maximum allowed value. The WTRU may scale down an enhanced dedicated channel (E-DCH) dedicated physical data channel (E-DPDCH) first before other channels. For multiple E-DCH streams, the WTRU may calculate an E-DPDCH power offset based on an additional power offset factor due to multiple stream transmission.

Abstract: A method and apparatus for radio link synchronization and power control in CELL_FACH state and idle mode are disclosed. A wireless transmit/receive unit (WTRU) transmits a random access channel (RACH) preamble and receives an acquisition indicator acknowledging the RACH preamble via an acquisition indicator channel (AICH) and an index to an enhanced dedicated channel (E-DCH) resource. The WTRU determines a start of an E-DCH frame. An F-DPCH timing offset is defined with respect to one of the RACH access slot and an AICH access slot carrying the acquisition indicator. A relative F-DPCH timing offset may be signaled to the WTRU and the WTRU may determine a start of an E-DCH frame based on the relative F-DPCH timing offset and timing of an AICH access slot including the acquisition indicator. The WTRU may transmit a dedicated physical control channel (DPCCH) power control preamble before starting an E-DCH transmission.

Abstract: A wireless transmit receive unit (WTRU) may perform provide a report to a network. The WTRU may include a processor that is configured to receive a measurement configuration from the network, where the measurement configuration indicates a threshold and a resource pool on which to perform measurements. The resources pool may be used for communication between one or more mobile device. The processor may be configured to perform measurements on the resource pool and determine whether an energy level for the resource pool is above the threshold for a duration of time. The processor may also be configured to send a report to the network indicating that the energy level for the resource pool is above the threshold for the predetermined duration of time.

Abstract: A method and apparatus are used for detecting a radio link (RL) failure and a post verification process. A quality of a downlink fractional dedicated physical channel (F-DPCH) is monitored once a transmission on an enhanced dedicated channel (E-DCH) has begun. It is determined whether the quality of the downlink F-DPCH is below a predefined threshold. If the quality is below the predefined threshold, then an occurrence of an RL failure is declared and a transmission over the E-DCH in a cell forward access channel (CELL_FACH) state is terminated. In a case of the post verification failure, E-DCH resources are released.
