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 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： An uplink signal may be transmitted by a user equipment (UE) in a time interval using an uplink control channel. The uplink signal may include hybrid automatic repeat request (H-ARQ) control information related to received downlink data. If the UE determines that information indicating a coding and modulation is to be transmitted at a same time interval as the H-ARQ control information, the uplink signal may include the information that indicates the coding and modulation.

摘要： A wireless communication system is configured to monitor transmission sequence numbers (TSNs) assigned to protocol data units (PDUs) processed by the system. The system includes at least one user equipment (UE) (605) having, a queue, and a Node B (615) in communication with the UE. The UE determines that a data block having an expected TSN was not received, and generates a TSN status report message (625). The Node B retransmits a data block (630) including the expected TSN to the UE in response to the TSN status report message. The retransmitted data block is placed in a specific location in the queue designated by the TSN status report message.

摘要： A wireless communication method system for detecting and correcting transmission errors. The system includes at least one Wireless Transmit/Receive Unit (WTRU) in communication with a Node B. At step 405 the Node B sends a transmission signal (including a protocol data unit (PDU)) to the WTRU. The WTRU generates a Revert Message having a first field and a second field to indicate whether the transmission signal was successfully received at the WTRU. The WTRU transmits the Revert Message to the Node B. The Node B receives the first field (step 410) and the second field (step 420) and determines the contents (steps 415 and 425). The Node B compares the contents of the first field to the contents of the second field (step 430). The Node B resends the transmission signal to the WTRU if the contents of the first and second fields are not logically consistent (step 450).

摘要： A drifting wireless transmit/receive unit (WTRU) has an associated drift radio network controller (D-RNC) and an associated servicing radio network controller (S-RNC). The D-RNC sends a request message to the S-RNC requesting measurements of the drifting WTRU. The S-RNC receives the request message and sends an information message with the requested measurements to the D-RNC. The D-RNC receives the information message.

摘要： Method and apparatus for synchronizing base stations (30n) employing an independent synchronous source or identifying a base station (30n) as a master source. An RNC (C-RNC) (36, 38, 40) or a base station (30n) may designate one base station (30n) or UE (20, 22, 24) to acquire measurements derived from base stations (30n) to achieve synchronization. Synchronization activities may be regularly scheduled or may be undertaken when periodic measurements indicate that a drift value exceeds a given threshold.
