摘要： A method and system for an enhanced uplink (EU) operation in a wireless communication system during soft handover. The system comprises a wireless transmit/receive unit (WTRU), at least two Node-Bs, and a radio network controller (RNC). One Node-B may be designated as a primary Node-B, and the primary Node-B may control EU operation during soft handover including uplink scheduling and hybrid automatic repeat request (H-ARQ). Soft buffer corruption is avoided during soft handover by controlling H-ARQ by the primary Node-B. Alternatively, an RNC may control EU operation during soft handover including H-ARQ. In this case, an RNC generates final acknowledge/non-acknowledge (ACK/NACK) decision based on the error check results of the Node-Bs.

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 wireless communication method and apparatus for transferring buffered enhanced uplink (EU) data from a wireless transmit/receive unit (WTRU), i.e., a mobile station, to a Node-B. The EU data is generated and stored in a buffer of the WTRU. The WTRU transmits a message to the Node-B including a request for a desired transport format combination (TFC) or data traffic indicator. The Node-B schedules one or more allowed EU data transmissions between the WTRU and the Node-B by transmitting an EU data scheduling message to the WTRU. The WTRU transmits all of the EU data stored in the buffer to the Node-B if the allowed EU data transmissions are sufficient to support transmission of all of the EU data stored in the buffer. Otherwise, the WTRU transmits a portion of the EU data along with the desired TFC or detailed traffic volume measurement (TVM) information to the Node-B.

摘要： A method and apparatus for supporting an enhanced uplink soft handover (EU-SHO) operation for a wireless transmit/receive unit (WTRU) (115). The apparatus may be a multi-cell wireless communication system (200) including at least two EU-SHO Node-Bs (210) and a radio network controller (RNC) (205). The RNC (205) includes a medium access control (MAC) entity (215) that handles enhanced uplink dedicated channel (EU-DCH) functionalities. The RNC (205) is configured according to a first architecture when an EU-SHO operation for the WTRU (115) is not taking place, and the RNC (205) is configured according to a second architecture when the WTRU (115) is operating in an EU-SHO operation. According to the second architecture, the MAC entity (215) of the RNC (205) includes an ACK/NACK generator (225) which generates signals indicating whether or not an EU transmission originating from the WTRU (115) has been successfully received by the RNC (205) and an uplink scheduler for scheduling an EU transmission for the WTRU (115).

摘要： A method and apparatus for processing data blocks during soft handover. The apparatus may be a wireless communication system including at least two enhanced uplink soft handover (EU-SHO) Node-Bs and a radio network controller (RNC). Each Node-B decodes a received data block and forwards the decoded data block to the RNC. If the RNC receives at least one copy of a successfully decoded data block, the RNC uses a re-ordering function entity to process the copy of the successfully decoded data block to support in-sequence delivery to higher protocol layers. If the RNC receives more than one copy of a successfully decoded data block, the RNC discards the extra successfully decoded data block copies. The RNC is either a serving-RNC (S-RNC) or a controllingRNC (C-RNC). Each Node-B includes a medium access control (MAC) entity that handles enhanced uplink dedicated channel (EU-DCH) functionalities.

摘要： 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.

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.
摘要翻译：一种用于最小化在无线发射/接收单元（WTRU）和节点B之间发生的冗余增强上行链路（EU）分配请求和故障隔离的EU传输故障的方法和装置。 WTRU通过上行链路（UL）EU信道向节点B发送增强型专用信道（E-DCH）分配请求。在一个实施例中，如果在预定时间段内不能提供E-DCH分配，则节点B经由下行链路（EU）信令信道向WTRU发送确认消息，而不发送E-DCH分配信息。该请求在节点B中排队，并且WTRU禁止发送相同的请求，直到时间段到期或资源变得可用。在另一个实施例中，通过确定E-DCH分配请求是经由UL EU信道未成功传送还是经由DL EU信令信道未成功传送的信道分配信息被采取适当的动作来校正EU传输失败。

摘要： A wireless communication method and apparatus for reporting traffic volume measurement (TVM) information used to support enhanced uplink (EU) data transmissions between a wireless transmit/receive unit (WTRU), i.e., a mobile station, and a Node-B. After storing EU data in a buffer, the WTRU sends an initial TVM information request message to the Node-B indicating that the WTRU has EU data available to send to the Node-B. In response, the Node-B schedules one or more allowed EU data transmissions. The WTRU transmits at least a portion of the stored EU data to the Node-B via the allowed EU data transmissions. In one embodiment, the initial TVM information request message is sent by the WTRU only after the quantity of EU data stored in the buffer of the WTRU exceeds an established threshold. Otherwise, all of the stored EU data is transferred to the Node-B without requiring scheduling by the Node-B.

摘要： A method and system for controlling the transmission power of at least one downlink (DL) enhanced uplink (EU) signaling channel such that enhanced dedicated channel (E-DCH) DL signaling is delivered efficiently and reliably. The system includes at least one wireless transmit/receive unit (WTRU), at least one Node-B and a radio network controller (RNC). At least one of the WTRU and the Node-B compute EU transmission failure statistics on the DL EU signaling channel and report the EU transmission failure statistics to the RNC. The RNC then adjusts a transmission power offset of the DL EU signaling channel to be used in determining transmission power level of the DL EU signaling channel at the Node-B based on the EU transmission failure statistics.
