摘要： A technique of configuring link layer entities for a handover is described. In a method embodiment, the technique includes receiving from a recipient of protocol data units a supplemental status report for an existing ARQ connection in context with an imminent handover, determining service data units corresponding to buffered protocol data units taking into account information included in the supplemental report, and transferring the determined service data units to a link layer entity which is to establish a new ARQ connection to the recipient. The forced status synchronisation that is based on the supplemental report prevents the transfer of service data units that have already been successfully received at the recipient.

摘要： A communication device is described that comprises a first data unit buffer for holding data units of a first communication protocol and a second data unit buffer for holding data units of a second communication protocol. The first communication protocol is a communication protocol suitable for transmitting data units from a sending peer of said first communication protocol to a receiving peer of said first communication protocol over one or more relay peers of said first communication protocol. The first communication protocol provides for at least a first type (RACK) of receipt information that is indicative of a correct receipt at a relay peer and a second type (ACK) of receipt information that is indicative of a correct receipt at said receiving peer. The second can be a conventional ARQ protocol or a protocol using the two types of receipt information. A control system is arranged to control a generation of said data units of said second communication protocol such that a data symbol stream carried in said data units of said first communication protocol is also carried in said data units of said second communication protocol, and the control system is arranged to implement the control procedure for controlling a transmission of said data units of said first communication protocol in such a way that if all the data symbols of said data symbol stream contained in a given data unit of said first communication protocol are successfully transferred into said second data unit buffer, then said control procedure acts as if said first type (RACK) of receipt information had been received for said given data unit.

摘要： A method and an apparatus for transmitting error-tolerant data is disclosed employing the ARQ technique, wherein the retransmission of erroneous data is performed up to the point where the remaining amount of errors is acceptable (for instance because the erorrs will not be perceived by the recipient of the information, which can be a person or a higher level protocol with additional error correction capabilities). The number of data blocks (RLC) detected as erroneous is employed to define a reliability measure (RM) and a request for retransmission of the erroneous data blocks is performed until a desired reliability threshold (RT) is reached. An additional threshold with a higher value than the first one can be employed to request for optional retransmission when the reliability measure (RM) is between the first and the second threshold. The retransmission will be performed only if further conditions such as channel availability are met.
摘要翻译：使用ARQ技术公开了一种用于发送容错数据的方法和装置，其中执行错误数据的重传直到剩余的错误量是可接受的（例如，由于错误的错误数据不会被信息的接收者，其可以是具有附加纠错能力的人或更高级协议）。使用检测为错误的数据块（RLC）的数量来定义可靠性度量（RM），并且执行错误数据块的重传请求，直到达到期望的可靠性阈值（RT）。当可靠性测量（RM）在第一和第二阈值之间时，可以采用具有比第一阈值更高的值的附加阈值来请求可选重传。只有在满足诸如频道可用性等更多条件的情况下，才会执行重传。

摘要： It is proposed to modify data unit handling on the side of a sender (e.g. a sending end-point or a proxy) by introducing congestion notification prevention information into data units, such that a queue buffer that implements a procedure for performing congestion notification with respect to one or more queued data units (e.g. dropping and/or marking data units with explicit congestion information) is capable of preventing the performance of a congestion notification at least with respect to the data units containing the congestion notification prevention information.

摘要： A flexible Radio Link Control (RLC) protocol for a mobile communication system is provided, whereby a plurality of different RLC functions are defined. These different RLC functions can be combined in a number of different ways to produce a complete and functional, but more flexible RLC protocol than the existing protocol. For example, a new set of rules are provided for determining how and/or when to poll for, or send, a status report for Automatic Repeat Request (ARQ) purposes. As such, for a specific service configuration, one set of the rules can be used, and for a different service configuration, another set of the rules can be used. In this way, the rules can be conformed suitably to the type of service involved.
摘要翻译：提供了一种用于移动通信系统的灵活的无线链路控制（RLC）协议，由此定义了多个不同的RLC功能。这些不同的RLC功能可以以多种不同的方式组合以产生比现有协议更完整且功能更强的RLC协议。例如，提供了一组新的规则来确定如何和/或何时轮询或发送用于自动重传请求（ARQ）的状态报告。因此，对于特定服务配置，可以使用一组规则，并且对于不同的服务配置，可以使用另一组规则。以这种方式，规则可以适当地符合所涉及的服务类型。

摘要： In a mobile network, the transmission of downlink data blocks (303, 307) to one or more terminal devices (200, 210) is accomplished on the basis of a retransmission protocol with a first feedback time (F1) defining a time interval between transmission of a first data block (303) and transmission of a first feedback message (308) being different from a second feedback time (F2) defining a time interval between transmission of a second data block (307) and transmission of a second feedback message (309). The first feedback message (308) indicates whether the first data block (303) was successfully received, and the second feedback message (309) indicates whether the second data block (307) was successfully received. A base station (100) of the mobile network controls the terminal device (200, 210) to send the second feedback message (309) on other resources than used for transmission of the first feedback message (308).
