    摘要: A wireless communication method and apparatus for detecting and decoding enhanced dedicated channel (E-DCH) hybrid automatic repeat request (H-ARQ) indicator channel (E-HICH) transmissions are disclosed. A wireless transmit/receive unit (WTRU) receives E-HICH transmissions and detects an H-ARQ indicator transmitted via the E-HICH by performing a binary hypothesis test. The WTRU then generates an acknowledgement (ACK) message or a non-acknowledgement (NACK) message based on the detected H-ARQ indicator. A reliability test may be further performed to improve performance, whereby the binary hypothesis test may be performed only if the reliability test is passed.

    摘要: Methods and apparatus for detecting errors or events in a wireless transmit/receive unit (WTRU) and/or a base station comprising a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a medium access control (MAC) layer, and a physical (PHY) layer are disclosed. In addition, the RRC layer may initiate an RLC re-establishment procedure upon detecting an error, or upon receiving an indication of an error or an event detected by any one of the RRC, PDCP, RLC, MAC and PHY layers.

    摘要: A method system and components for outer loop power control particularly useful for non-real time/real time data services uses data transmitted in many bursts of short duration, called Temp-DCH allocations. A target metric, preferably, target SIR, is adjusted with differing step up and step down levels to converge on a relatively low steady state level of step up and step down target metric adjustments. The initial target SIR and the transient step size for target SIR adjustment is determined in a dynamic way in the outer loop power control for each Temp-DCH allocation of non-real time data.

    摘要: A UE system implements dynamic link adaptation by adding or changing control information to notify a receiver which timeslots and codes are currently active and which timeslots should be avoided. The UE provides synchronization such that the receiver knows which timeslots and codes the UE has used to map the coded composite transport channel onto physical channels. The UE attempts to avoid the timeslots which are experiencing transmission difficulties, while attempting to utilize the timeslots which are not experiencing transmission problems.

    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 apparatus for controlling an optimization of handover procedures between universal terrestrial radio access (UTRA) release 6 (R6) cells and UTRA release 7 (R7) cells are disclosed. When a wireless transmit/receive unit (WTRU) is moving between an R6 cell and an R7 cell, or between R7 cells, a handover is initiated from a source Node-B to a target Node-B. In the R7 cell, the enhanced medium access control (MAC) functionality including flexible radio link control (RLC) protocol data unit (PDU) size and high speed MAC (MAC-hs) segmentation and multiplexing of different priority queues are supported. After the handover, a MAC layer and/or an RLC layer are reconfigured or reset based on functionality supported by the target Node-B.
