摘要： A wireless communication method and system for controlling the current data bit rate of a radio link (RL) to maintain the quality of the RL. The system includes a core network (CN), a radio network controller (RNC) and at least one wireless transmit/receive unit (WTRU). The RL is established between the RNC and the WTRU. The RNC establishes a guaranteed data bit rate, a maximum data bit rate and a current data bit rate associated with the RL. When the RNC senses an event which indicates that the quality of the RL has substantially deteriorated, the RNC reduces the value of the current data bit rate. Then, in a recovery process, if a similar event does not occur during an established waiting period, the RNC restores the current data bit rate back to the maximum data bit rate.

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 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： In a radio access network, novel systems and methods reduce processing delay, and improve integration with IP networks, by separating user data from connection management and control data at a Node B or at a base station. The user data are routed to an IP (Internet Protocol) switch, whereas the connection management and control data are routed to a centralized radio network controller (RNC). Pursuant to a second embodiment of the invention, a centralized RNC provides improved radio resource management (RRM) functionality by handing all connection management and control data for a plurality of Node B's, thereby simplifying the switching of user data throughout the radio access network. Pursuant to a third embodiment of the invention, a smart IP switch is equipped to switch user data without core network (CN) involvement. Downlink user data are switched independently of uplink user data.

摘要： A wireless digital communication system includes a base station in communication with a plurality of user equipment mobile terminals (UEs). The system prioritizes the forwarding of blocks of downlink data to designated ones of the UEs. The system employs adaptive modulation and coding (AM&C) to achieve improved radio resource utilization and provides optimum data rates for user services. Blocks of downlink (DL) data are received by the base station which requests downlink (DL) channel quality measurements only from those mobile terminals (UEs) with pending downlink transmissions. The UEs respond to the request by measuring and reporting DL channel quality to the base station, which then allocates resources such that the UEs will make best use of radio resources. The base station notifies the UEs of the physical channel allocation indicating the modulation/coding rate and allocated slots followed by transmission of blocks of downlink data which are transmitted to the UEs.

摘要： An enhanced uplink user equipment is in soft handover. A radio network controller selects a primary Node-B out of a plurality of Node-Bs supporting the soft handover. The radio network controller receiving successfully received enhanced uplink data packets from the plurality of Node-Bs. The radio network controller reordered the successfully received enhanced uplink data packets for in-sequence deliver. The primary Node-B sends specified scheduling information to the user equipment that the other Node-Bs does not transmit. At least the primary Node-B transmits acknowledgements and negative acknowledgements to the user equipment.

摘要： A sequence of codes are provided for potential assignment to a user in a wireless hybrid time division multiple access (TDMA)/code division multiple access (CDMA) communication system. At least one timeslot is selected to support the communication. For each selected timeslot, at least one code is selected. If more than one code is selected, the selected codes are consecutive in the provided codes sequence. For at least one of the selected timeslots, an identifier of a first and last code of the selected consecutive codes is signaled. The user receives the signaled identifier and uses the selected consecutive codes, as identified, to support the communication.

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.
