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.

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.
摘要:
A medium access control (MAC) layer architecture and functionality for supporting enhanced uplink (EU). A MAC entity for EU, (i.e., a MAC-e entity), is incorporated into a wireless transmit/receive unit (WTRU), a Node-B and a radio network controller (RNC). The WTRU MAC-e handles hybrid-automatic repeat request (H-ARQ) transmissions and retransmissions, priority handling, MAC-e multiplexing, and transport format combination (TFC) selection. The Node-B MAC-e entity handles H-ARQ transmissions and retransmissions, E-DCH scheduling and MAC-e de-multiplexing. The RNC MAC-e entity provides in-sequence delivery and handles combining of data from different Node-Bs.
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 supporting an enhanced uplink soft handover (EU-SHO) operation for a wireless transmit/receive unit (WTRU). The apparatus may be a multi-cell wireless communication system including at least two EU-SHO Node-Bs and a radio network controller (RNC). The RNC includes a medium access control (MAC) entity that handles enhanced uplink dedicated channel (EU-DCH) functionalities. The RNC is configured according to a first architecture when an EU-SHO operation for the WTRU is not taking place, and the RNC is configured according to a second architecture when the WTRU is operating in an EU-SHO operation. According to the second architecture, the MAC entity of the RNC includes an ACK/NACK generator which generates signals indicating whether or not an EU transmission originating from the WTRU has been successfully received by the RNC, and an uplink scheduler for scheduling an EU transmission for the WTRU.
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 controlling-RNC (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 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.
摘要:
An integrated circuit (IC) for processing data blocks received from a plurality of data sources. The IC includes at least one re-ordering function entity, higher protocol layers and an interface for receiving at least one copy of a successfully decoded data block from the data sources. The IC uses the re-ordering function entity to process the copy of the successfully decoded data block to support in-sequence delivery to the higher protocol layers. The IC discards extra copies of a successfully decoded data block received from the data sources. Each data source may be an enhanced uplink soft handover (EU-SHO) Node-B. Each data source may include a medium access control (MAC) entity that handles enhanced uplink dedicated channel (EU-DCH) functionalities. The IC may be located in a serving radio network controller (S-RNC) that processes data blocks forwarded to the S-RNC by the data sources during soft handover.
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 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.
