摘要： A method and apparatus for signaling the release of a persistent resource in long term evolution (LTE) are disclosed. An indication of the release of a downlink (DL) persistent resource is received by a wireless transmit receive unit (WTRU) from an evolved Node-B (eNB) via a physical downlink control channel (PDCCH). A positive acknowledgement (ACK) is transmitted by the WTRU which denotes that the indication has been received. The PDCCH or a medium access control (MAC) CE may be used by the eNB to signal the indication. At least one bit may be added to contents of the PDCCH to signal whether the PDCCH is for DL persistent or dynamic resource allocation. The DL persistent resource is then released and an indication that the DL persistent resource has been released is transmitted.

摘要： A method and apparatus for minimizing redundant enhanced uplink (EU) allocation requests and fault-isolating EU transmission failures that occur between a wireless transmit/receive unit (WTRU) and a Node-B. The WTRU transmits an enhanced dedicated channel (E-DCH) allocation request to the Node-B over an uplink (UL) EU channel. 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 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.

摘要： A wireless communication method and system for controlling an enhanced uplink (EU) radio access bearer (RAB). The wireless communication system includes at least one wireless transmit/receive unit (WTRU), at least one Node-B and a radio network controller (RNC). The RNC configures an EU RAB to operate on an enhanced dedicated channel (E-DCH). At least one of the WTRU and the Node-B report EU traffic statistics and EU performance statistics to the RNC. The RNC then adjusts the configuration of the EU RAB in accordance with the received EU traffic statistics, the EU performance statistics, and information collected by the RNC itself.

摘要： A method and apparatus for controlling transmissions of data via an enhanced dedicated channel (E-DCH) are disclosed. A list of available transport format combinations (TFCs) is generated based on a plurality of dedicated channel medium access control (MAC-d) flows. An enhanced uplink medium access control (MAC-e) protocol data unit (PDU) is generated using a TFC which is selected from the list of available TFCs. The MAC-e PDU is forwarded to a hybrid-automatic repeat request (H-ARQ) process unit for transmission. The list of available TFCs is continuously updated by eliminating and recovering TFCs based on remaining E-DCH power, an E-DCH transport format combination set (TFCS), a power offset of a highest priority MAC-d flow that has E-DCH data to transmit, and a gain factor for each TFC.

摘要： A wireless communication method and system for supporting an enhanced uplink dedicated channel (EU-DCH) inter-Node-B serving cell change. The system includes at least one wireless transmit/receive unit (WTRU) for transmitting data blocks, a target Node-B, a source Node-B and a serving radio network controller (S-RNC). The S-RNC includes a re-ordering buffer which stores data blocks correctly received from the WTRU. The S-RNC informs the target Node-B of a need for an EU-DCH inter-Node-B serving cell change from the source Node-B to the target Node-B. A medium access control (MAC) entity that handles EU-DCH functionalities is set up in the target Node-B. Hybrid automatic repeat request (HARQ) processes and transmission sequence numbers (TSNs) are not reset at the WTRU. Using a new data indicator, the WTRU transmits a data block to the target Node-B that was previously transmitted to the source Node-B, but was not correctly received by the source Node-B.

摘要： An optically amplified wavelength division multiplexing network has the functionality to add/drop channels at the optical add/drop multiplexing (OADM) nodes. The OADM node includes a receiver amplifier, an OADM module, and a transmitter amplifier. Once the OADM node detects a loss of signal (LOS) due to a fiber cut or network element failure upstream, the receiver amplifier is kept in operation as a noise source. The output of the receiver amplifier is immediately raised by increasing pump power to compensate for the LOS. The noise power received at the transmitter amplifier from the receiver amplifier is substantially equal to the signal power expected before LOS. The transient effect of downstream optical amplifiers is therefore completely suppressed and the inter-channel stimulated Raman scattering (SRS) induced spectrum tilt does not change. After the noise power is raised, the receiver amplifier may be shut down at a speed much slower than the speed of downstream amplifier control circuitry.

摘要： A method for processing enhanced dedicated channel (E-DCH) data in a wireless transmit/receive unit (WTRU) includes sending two messages. A first message is sent from a physical layer to a medium access control (MAC) layer, and triggers MAC layer processing of E-DCH data. A second message is sent from the MAC layer to the physical layer, and enables the physical layer to compute control parameters for physical layer processing of the E-DCH data before the MAC layer processing of the E-DCH data is completed.
