摘要： In a wireless communication network where base stations receive protocol data units (PDUs) from mobile stations for decompression and deciphering for ordered, sequential transfer as service data units (SDUs) to an associated core network, the teachings presented herein provide a method of supporting seamless handover of a mobile station from a source base station to a target base station. By way of example, the teachings herein apply to a network based on the E-UTRA specifications, as promulgated by the 3GPP. However, that example is non-limiting, as the teachings herein apply to any network that employs in-sequence data delivery and duplicate data detection at handover. Broadly, the source base station forwards out-of-sequence SDUs and corresponding sequence number information to the target base station in support of seamless handover, and the target base station uses that information to request retransmissions as needed for packet reordering.

摘要： Methods for efficiently controlling the retransmission of data units in a wireless telecommunication system, wherein multiple complementary feedback mechanisms are used to control retransmission. A receiver attempts to decode each received data unit. If a data unit is successfully decoded, the receiver transmits positive feedback to the transmitter; if a data unit is not successfully decoded, the receiver transmits negative feedback to the transmitter. In all cases, the transmitter employs at least first and second feedback mechanisms for transmitting the positive and negative feedback. In an exemplary embodiment, acknowledgement (ACK) and non-acknowledgement (NACK) messages are sent in response to the receipt of each data unit on a first unreliable channel and Status Messages identifying sequence numbers of particular data units are periodically transmitted on a second reliable channel; the receiver preferably removes data units from its transmit window only upon receipt of a Status Message indicating successful decode.

摘要： A method of scheduling data for transmission over the air interface of a wideband code division multiple access network, said data being transported over the air interface on a downlink shared channel. The method comprises receiving data in the form of IP packets at a radio network controller, segmenting said IP packets into protocol data units, and forwarding said protocol data units from the radio network controller to a radio base station serving one or more user terminals. The radio network controller identifies to the radio base station the protocol data units belonging to a common IP packet. At the radio base station, each protocol data unit is scheduled for transmission over the air interface in dependence upon the IP packet to which it belongs.

摘要： A radio base station suitable for performing a handover operation for a LTE-variant of a radio access network comprises a transceiver and a status report requester. The transceiver is configured to facilitate wireless transmission between the radio base station and a wireless terminal over an air interface, including transmission of a radio link bearer for the connection over a downlink from the radio base station to the wireless terminal. The status report requester is configured to determine, according to one or more pre-defined criteria, whether to request from the wireless terminal a status report for a radio bearer prior to the radio base station transferring user data for the connection to another radio base station in conjunction with a handover.

摘要： A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.
