摘要： A method and apparatus for implementing data security and automatic repeat request (ARQ) in a wireless communication system are disclosed. Cipher entities are included in a wireless transmit/receive unit (WTRU) and an access gateway (aGW), and outer ARQ, (or radio link control (RLC)), entities are included in the WTRU and an evolved Node-B (eNode-B). Each cipher entity is located on top of an outer ARQ entity. The cipher entities cipher and decipher a data block by using a generic sequence number (SN) assigned to the data block. The outer ARQ entities may segment the ciphered data block to multiple packet data units (PDUs), may concatenate multiple ciphered data blocks to a PDU, or may generate one PDU from one data block. The outer ARQ entities may segment or re-segment the PDU when a transmission failure occurs.

摘要： A method and apparatus for selecting a transport format combination (TFC) are disclosed. A TFC recovery and elimination unit generates an allowed transport format combination set (TFCS) subset by recovering supported TFCs and eliminating not supported TFCs based on allocated radio resources and parameters that are new. A multiplexing and transmission sequence number (TSN) setting unit generates a medium access control (MAC) protocol data unit (PDU) by multiplexing at least one higher layer PDU within a maximum supported MAC PDU size. A TFC selection and padding unit selects a TFC for the MAC PDU from the allowed TFCS subset and performs padding of the MAC PDU, if necessary, so that the MAC PDU fits into the selected TFC. For retransmission, a new allowed TFCS subset may be generated based on new radio resources and parameters and the MAC PDU may be fragmented.

摘要： A method and system for providing control information for supporting high speed downlink and high speed uplink packet access are disclosed. A Node-B assigns at least one downlink control channel and at least one uplink control channel to a wireless transmit/receive unit (WTRU). The downlink control channel and the uplink control channel are provided to carry control information for both the downlink and the uplink. Conventional control channels for downlink and uplink are combined into a reduced set of control channels for uplink and downlink. The Node-B and the WTRU communicate control information via the downlink control channel and the uplink control channel. The WTRU receives downlink data and transmits uplink data, and the Node-B receives uplink data and transmits downlink data based on the control information transmitted via the downlink control channel and the uplink control channel.

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.

摘要： Receiving multimedia broadcasts/multicast services (MBMS) by a user equipment (UE) comprises when an MBMS service is transmitted as a point-to-point transmission, receiving information associated with the point-to-point transmission of a point-to-point MBMS service. Point-to-point MBMS segments of the point-to-point transmission are received over a dedicated traffic channel in response to the received point-to-point transmission information. When an MBMS service is transmitted as a point-to-multipoint transmission, receiving information associated with the point-to-multipoint transmission of a point-to-multipoint MBMS service. Point-to-multipoint MBMS segments of the point-to-multipoint transmission are received over secondary common control physical channels (S-CCPCHs) in response to the received point-to-multipoint transmission information. The S-CCPCHs originates from a plurality of cells and the transmission of the point-to-multipoint MBMS segments are not synchronized in time between the cells. The point-to-multipoint MBMS segments are reassembled.

摘要： A method and system for detecting radio link (RL) failures between a wireless transmit/receive unit (WTRU) and a Node-B are disclosed. When signaling radio bearers (SRBs) are supported by high speed uplink packet access (HSUPA), an RL failure is recognized based on detection of improper operation of at least one of an absolute grant channel (AGCH), a relative grant channel (RGCH), a hybrid-automatic repeat request (H-ARQ) information channel (HICH), an enhanced uplink dedicated physical control channel (E-DPCCH) and an enhanced uplink dedicated physical data channel (E-DPDCH). When SRBs are supported by high speed downlink packet access (HSDPA), an RL failure is recognized based on detection of improper operation of at least one of a high speed shared control channel (HS-SCCH), a high speed physical downlink shared channel (HS-PDSCH) and a high speed dedicated physical control channel (HS-DPCCH).

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： In a wireless communication system including a wireless transmit/receive unit (WTRU) which transfers data to a Node-B, data transmission parameters such as modulation and coding scheme (MCS) and transport block set (TBS) size are dynamically adjusted on a transmission time interval (TTI) basis, and hybrid-automatic repeat request (H-ARQ) processes used to control the transfer of data between the WTRU and the Node-B are initiated and released, as required. The WTRU transmits and retransmits data to the Node-B through an enhanced uplink (EU) dedicated channel (E-DCH) in accordance with data feedback information received from the Node-B. The WTRU queues data for transmission, and determines a transmission status of the data. The transmission status is set to one of “new transmission,” “successful transmission,” “retransmission” and “restarted transmission.” For each TTI, the WTRU initiates an EU transmission to the Node-B which identifies the assigned H-ARQ process, TBS size and MCS.

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.
