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.
摘要翻译：根据本发明的方法和装置解决和/或防止由ACK / NACK错误引起的HARQ系统中丢失的协议同步。一个实施例检测基于NDI的重传协议的丢失的同步错误，并通过发送显式的RESET消息来恢复同步。响应于RESET消息，发射机中止当前PDU的传输，并发送新的PDU和相应的NDI。另一个实施例通过逐个分组地发送调度许可来防止协议同步错误。接收机基于接收到的PDU的错误评估向发射机发送后续的显式调度许可。发射机不会发送下一个PDU，除非它接收到后续的显式调度授权。

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.
摘要翻译：在无线通信网络中，其中基站从移动台接收用于解压缩和解密的协议数据单元（PDU），用于有序的顺序传送作为服务数据单元（SDU）到相关联的核心网络，本文给出的教导提供了一种支持无缝将移动台从源基站切换到目标基站。作为示例，本文的教导适用于由3GPP公布的基于E-UTRA规范的网络。然而，该示例是非限制性的，因为本文的教导适用于在切换时采用顺序数据传递和重复数据检测的任何网络。广泛地说，源基站将无序SDU和相应的序列号信息转发给目标基站以支持无缝切换，目标基站使用该信息来根据需要重新分组以重新分组。

摘要： A radio base station (28) suitable for performing a handover operation for a LTE-variant of a radio access network comprises a transceiver (34) and a status report requester (60). The transceiver (34) is configured to facilitate wireless transmission between the radio base station (28) and a wireless terminal (30) 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.

摘要： According to the present invention, a receiving node of a telecommunications network (20) (e.g. a radio base station (22) in uplink, or a mobile terminal (24) in downlink) transmits a single acknowledgement message to a transmitting node (e.g. a mobile terminal (24) in uplink, or a radio base station (22) in downlink) in respect of signals received over a plurality of frequency-aggregated carriers (component carriers) (10) between the transmitting and receiving nodes. If all signals are decoded correctly in the receiving node, a positive acknowledgement message (ACK) is sent to the transmitting node; if not all signals are decoded correctly, a negative acknowledgement message (NACK) is sent, or no acknowledgement message is sent. In this way, a single acknowledgement message can be sent for signals received over multiple carriers. The acknowledgement message can have the same format as legacy standards (for example, as specified in Release 8 of the 3GPP specifications), providing compatibility with existing equipment. The number of messages is also reduced compared with the straightforward approach of transmitting individual acknowledgement messages per component carrier.
摘要翻译：根据本发明，电信网络（20）（例如，上行链路中的无线电基站（22）或下行链路中的移动终端（24））的接收节点向发送节点（例如，关于在发送节点和接收节点之间的多个频率聚合载波（分量载波）（10）上接收的信号，上行链路中的移动终端（24）或下行链路中的无线电基站（22）。如果所有信号在接收节点中被正确地解码，则肯定确认消息（ACK）被发送到发送节点; 如果不是全部信号被正确地解码，则发送否定确认消息（NACK），或者不发送确认消息。以这种方式，可以针对在多个载波上接收的信号发送单个确认消息。确认消息可以具有与传统标准相同的格式（例如，如3GPP规范的版本8中所述），提供与现有设备的兼容性。与每个分量载波发送各个确认消息的简单方法相比，消息的数量也减少了。

摘要： In a method for the transmission of data packets (D) from a transmitter (TR) to a receiver (RE) identification of transmitted data packets are stored. Defective data packets (D) are detected by the receiver (RE), status messages (S) which request defective data packets for retransmission are sent from the receiver (RE) to the transmitter (TR) and retransmissions of requested data packets are performed according to the status messages (S). The transmitter (TR) evaluates a first status message (S 11 ) with an identification of at least one first requested data packet and retransmits the first data packet. The transmitter (TR) then initializes a timing unit according to the retransmission of the first data packet, wherein the timing unit or a threshold for the timing unit is attributable to the first data packet. When the transmitter evaluates a further status message (S 12 ) and detects at least one further data packet that is requested for a retransmission, it selects the further data packet if the timing unit has reached the threshold or if the identification of the furhter data packet is different from the identification of the first data packets. Only the selected data packets are retransmitted. A transmitter and software programs embodying the invention are also described.

摘要： The present invention relates to a link layer control protocol implementation in a communication system. To improve operative efficiency of the link layer control protocol implementation it is suggested to delay issuance of a retransmission request for a missing data unit during a retransmission delay time period. Therefore, according to the present invention a retransmission request is not issued immediately upon detection of a missing data unit. Therefore, the present invention avoids issuance of false alarm for the missing data unit when it is received during the retransmission delay period.

摘要： In a method for the transmission of data packets (0) from a transmitter (TR) to a receiver (RE), defective data packets (0) are detected and a first status message (81) comprising an indication of defective data packets is sent from the receiver (RE) to the transmitter (TR). A retransmission of defective data packets is performed according to the first status message (S1). The receiver (RE) initializes a timing unit according to the sending of the first status message (S 1 ) and determines later that a further status message (S 2 ) indicating defective data packets is required. Then, defective data packets are selected for the further status message (S 2 ). A defective data packet is selected if it is not indicated in the first status message (S 1 ) or if the timing unit has reached a threshold. Only the indications of the selected data packets are included in the further status message (S 2 ) and the receiver sends the further status message (S 2 ). A receiver and software programs embodying the invention are also described.

摘要： In a method and device the TCP load offered in the uplink is manipulated such that an offered load asymmetry is achieved. Using such an arrangement it is possible to compensate for a link asymmetry when uplink and downlink connections are sharing the same uplink buffer in order to increase performance of the downlink. The method and device are capable of increasing the download performance both in the case when TCP connections are terminated in a different device than the terminal where the link layer is terminated, as well as when the TCP connections are terminated in the same device as the link-layer.

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.
