摘要： Methods and apparatus for signaling scheduling information in a multi-carrier wireless communications system (700), as well as corresponding methods and apparatus for processing such signaling information, are disclosed. An exemplary method comprises scheduling (610) first and second transport blocks for simultaneous transmission during a first transmission interval on first and second component carriers, and transmitting (620) a common re-transmission process identifier for the first transmission interval. The method further comprises scheduling (640) at least one of the first and second transport blocks for re-transmission during a second transmission interval, along with a third transport block, and transmitting (660) second scheduling information for the second transmission interval, the second scheduling information comprising the same common re-transmission process identifier.

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： A method is provides in a receiving node for handling status information of data units transmitted from a sending node to the receiving node over a radio link. The receiving node establishes (401 ) that a number of data units that has been transmitted by the sending node are missing. The receiving node sends (402) a reduced status message to the sending node over the radio link, which message is reduced such that it comprises the negative acknowledgement for a first part of missing data units and omits negative acknowledgements for the rest of the missing data units. The omitted negative acknowledgement for the rest of the missing data units will not erroneously be interpreted as correctly received data units by the sending node.

摘要： Method and arrangement in a first node for requesting a status report from a second node. The first node and the second node are both comprised within a wireless communication network. The status report comprises positive and/or negative acknowledgement of data sent from the first node, to be received by the second node. The first node comprises a first counter configured to count the number of transmitted Protocol Data Units, PDUs, and a second counter configured to count the number of transmitted data bytes. The method and arrangements comprises initialising the first and the second counter to zero, transmitting data to be received by the second node, comparing the value of the first and the second counters with a first threshold limit value and a second threshold limit value and requesting a status report from the second node if any of the threshold limit values is reached or exceeded.

摘要： A method of transmitting a status report from a receiving terminal to a transmitting terminal is disclosed. A receiving terminal generates a status report according to a first retransmission protocol implemented by a higher layer protocol layer and sends the status report to a transmitting terminal in one or more data units of a lower layer protocol. If the lower layer data units are not successfully received, the lower layer protocol provides a failure indication, referred to as a local NACK, to the higher layer protocol. In response to the failure indication, the higher layer protocol generates an updated status report and sends the updated status report from the receiving terminal to the transmitting terminal.
摘要翻译：公开了一种从接收终端向发送终端发送状态报告的方法。接收终端根据由较高层协议层实现的第一重传协议生成状态报告，并以较低层协议的一个或多个数据单元将状态报告发送给发送终端。如果未成功接收到较低层数据单元，则较低层协议向较高层协议提供称为本地NACK的故障指示。响应于故障指示，较高层协议生成更新的状态报告，并将更新的状态报告从接收终端发送到发送终端。

摘要： A retransmission controller for a communication device uses a reordering timer to supervise a retransmission protocol. The retransmission controller starts the reordering timer when a first gap comprising one or more first missing data units is detected and the timer is inactive. The retransmission controller stops the reordering timer when all of said first missing data units are received even if second missing data units corresponding to a second gap preceding the first gap are missing. If the reordering timer expires before all of the first missing data units are received, the retransmission controller sends a retransmission request to the transmitter.
摘要翻译：用于通信设备的重传控制器使用重新排序定时器来监督重传协议。当检测到包括一个或多个第一缺失数据单元的第一间隙并且定时器不活动时，重传控制器启动重新排序定时器。即使在与第一间隙之前的第二间隙相对应的第二丢失数据单元丢失的情况下，重传控制器也停止重新排序定时器。如果在接收到所有第一丢失数据单元之前重新排序定时器期满，则重发控制器向发射机发送重传请求。

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： The invention discloses a method (700) for a cellular system (100), in which traffic can be exchanged between first (110, 120) and second (110, 120) transceivers. The traffic is sent in data units, each of which is given an identifier, and which data units may be divided into segments. A receiving transceiver (110, 120) may send status information in data frames or data units (200, 300) about properly received, partially received, or non-received data units to a sending transceiver, i.e. the transceiver from which the data was sent. In the case (705) of partially or non-received data units, the status information includes (710) information about whether the data unit or units were non-received or partially received, and in the case of one or more partially received data units, which (715) parts of those data units that were not received.
