    摘要: A method and apparatus are disclosed relating to ciphering and de-ciphering of packet units in wireless devices during retransmission in wireless communications. The packet units are re-segmented with the ciphering done on the re-segmented packet unit or on a radio link control protocol data unit (RLC PDU) with or without segmentation. Alternatively, the re-segmentation is done on the radio link control service data unit (RLC SDU) with or without segmentation. Alternatively, the ciphering process and multiplexing of the RLC PDU is done in the medium access control (MAC) layer of a MAC PU before undergoing a hybrid automatic repeat request (HARQ) process for retransmission. Further, the ciphering process in the RLC is done on a packet data convergence protocol packet data unit (PDCP PDU).

    摘要: A method and apparatus are described for implementing a reset procedure for radio link control (RLC) using radio resource control (RRC) signaling. A wireless transmit/receive unit (WTRU) receives a request for RLC reset. A processor at the WTRU comprises a RRC entity and a RLC entity. The RRC entity receives the request for a RLC reset in a radio resource control message. The RLC entity reassembles RLC service data units (SDUs) from any protocol data units (PDUs) that are received out of sequence at a receiving side of the RLC entity. The reassembled SDUs are delivered in sequence to a packet data convergence protocol entity (PDCP). At the receiving side of the RLC entity, any remaining PDUs that are not able to be reassembled are discarded. At a transmitting side of the RLC entity, all SDUs and PDUs stored in transmit buffers are discarded.

    摘要: A method and apparatus for signaling the release of a persistent resource in long term evolution (LTE) are disclosed. An indication of the release of a downlink (DL) persistent resource is received by a wireless transmit receive unit (WTRU) from an evolved Node-B (eNB) via a physical downlink control channel (PDCCH). A positive acknowledgement (ACK) is transmitted by the WTRU which denotes that the indication has been received. The PDCCH or a medium access control (MAC) CE may be used by the eNB to signal the indication. At least one bit may be added to contents of the PDCCH to signal whether the PDCCH is for DL persistent or dynamic resource allocation. The DL persistent resource is then released and an indication that the DL persistent resource has been released is transmitted.

    摘要: As part of carrier assignment and configuration for multicarrier wireless communications, a single uplink (UL) primary carrier may provide control information for multiple concurrent downlink (DL) carriers. Optionally, control information for each DL carrier may be transmitted over paired UL carriers. Carrier switching of UL and/or DL carriers, including primary and anchor carriers, may occur during normal operation or during handover, and may occur in only the UL or only the DL direction. A unidirectional handover is performed when only an UL carrier or only a DL carrier is switched as part of a handover. Switching of UL and/or DL carriers may be from one component carrier or a subset of carriers to another component carrier, another subset of carriers, or all carriers in the same direction.

    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: A method and apparatus for controlling enhanced dedicated channel (E-DCH) transmissions are disclosed. An enhanced uplink medium access control (MAC-e/es) entity processes a received scheduling grant to calculate a serving grant. The MAC-e/es entity determines whether both a hybrid automatic repeat request (H-ARQ) process for scheduled data and scheduled data are available. If an H-ARQ process for scheduled data and scheduled data are available, the MAC-e/es entity determines whether a serving grant exists. The MAC-e/es entity calculates a remaining power based on maximum allowed power and restricts an E-DCH transport format combination (E-TFC) based on the remaining power. The MAC-e/es entity selects an E-TFC using the serving grant and generates a MAC-e protocol data unit. The MAC-e/es entity may process the received scheduled grant is at each transmission time interval or may store the received scheduled grant in a grant list until there is E-DCH data to transmit.
