    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 radio access network comprises a serving radio network controller (S-RNC). The S-RNC receives successfully received medium access control (MAC) packet data units (PDUs), discards duplicates of MAC PDUs, reorders the non-discarded MAC PDUs based on serial numbers of the MAC PDUs and delivers the MAC PDUs to a radio link control protocol layer. A controlling radio network controller (C-RNC) provides information to Node-Bs under its control for use in scheduling uplink transmissions. A plurality of Node-Bs schedule uplink transmissions in response to the information provided by its C-RNC, transmit scheduling information to user equipments of its cells, receive MAC PDUs from user equipments of its cells using hybrid automatic repeat request and forward the successfully received MAC PDUs to an associated S-RNC.

    摘要: A method and apparatus for forwarding non-consecutive data blocks in enhanced uplink (EU) transmissions. A wireless transmit/receive unit (WTRU) and one or more Node-Bs include one or more automatic repeat request (ARQ)/hybrid-ARQ (H-ARQ) processes for supporting an enhanced dedicated channel (E-DCH). Data blocks transmitted by the WTRU are re-ordered in a re-ordering entity located in the Node-B(s) or a radio network controller (RNC). Once a missing data block is identified, a data forwarding timer in the Node-B(s) or RNC is initiated and subsequent WTRU transmissions are monitored to determine whether the missing data block has been discarded by the WTRU. Upon recognition of the discard of the missing data block, the non-consecutive data blocks are forwarded to higher layers.

    摘要: 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.

    摘要: A wireless communication method and apparatus for coordinating Node-Bs during handover for enhanced uplink (EU) transmission. In one embodiment, a radio network controller (RNC) initiates an inter-Node-B soft handover. A wireless transmit/receive unit (WTRU) establishes communication connections with a plurality of Node-Bs. A particular one of the Node-Bs is designated as being a primary Node-B, and each of other Node-Bs are designated as being a non-primary Node-B. The RNC informs all of the Node-Bs that the particular Node-B is a primary Node-B. The primary Node-B schedules EU transmission and performs ACK/NACK during soft handover. In another embodiment, the RNC initiates a hard handover for a WTRU connected to a source Node-B. The RNC sends an activation timer to the source Node-B to set the time for handover. As many previously negatively acknowledged (NACKed) data packets as possible are prioritized for retransmission in the source Node-B before the activation timer expires.

    摘要: A user equipment determines transport format combinations (TFCs) that are available for at a dedicated channel (DCH) based on at least a maximum transmit power for the user equipment. A TFC is selected from the available TFCs for the DCH. Based on a remaining power after the TFC selecting, enhanced uplink TFCs (E-TFCs) are selected that are available for an enhanced dedicated channel (E-DCH). An E-TFC is selected for the E-DCH from the available E-TFCs.
