    • PROBLEM TO BE SOLVED: To identify ACK and NACK with respect to data segments for which they are sent as responses.SOLUTION: Traffic is sent in the form of data units, an identifier is assigned to each data unit, and the data units are divided into segments. A transceiver on the receiving side transmits status information in the form of data frames or data units about whether the data units have been properly received, have been partially received, or have not been received to a transceiver on the sending side side, that is, to the transceiver which has transmitted the data. When the data units are partially received or are not received, the status information includes information about whether the data units are not received or are partially received. Then, when one or more data units are partially received, the status information includes information about which parts of the data units are not received.
    • 要解决的问题:识别关于作为响应发送的数据段的ACK和NACK。

      解决方案:以数据单元的形式发送业务,将标识符分配给每个数据单元,并将数据单元划分成多个段。 接收侧的收发器以数据帧或数据单元的形式发送关于数据单元是否已被正确接收,部分接收或尚未被接收到发送侧的收发器的状态信息,即, 到发送数据的收发器。 当数据单元部分接收或未被接收时,状态信息包括关于数据单元是否未被接收或部分接收的信息。 然后,当部分地接收到一个或多个数据单元时,状态信息包括关于哪些部分数据单元未被接收的信息。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a method and apparatus in a communication unit employing a wireless TDD or half duplex FDD transmission arrangement when communicating with a data sending party, for scheduling feedback reports for data blocks in received RX sub-frames, in TX sub-frames available for transmission.SOLUTION: An obtaining unit 402 in the communication unit receives allocation parameters (P) for the connection where the number of required feedback reports is greater than the number of allowed feedback reports. A scheduling unit 404 in the communication unit then schedules feedback reports (FR) in available TX sub-frames according to a predetermined spreading rule also known by the data sending party, instructing that the feedback reports are spread out or distributed evenly over the available TX sub-frames. In this way, the number of feedback reports in a TX sub-frame can be reduced.
    • 要解决的问题:为了在与数据发送方进行通信时,在采用无线TDD或半双工FDD传输装置的通信单元中提供方法和装置,用于调度在接收到的RX子帧中的数据块的反馈报告, 在TX子帧中可用于传输。 解决方案:通信单元中的获取单元402接收所需反馈报告的数量大于所允许的反馈报告数量的连接的分配参数(P)。 然后,通信单元中的调度单元404根据数据发送方也已知的预定的扩展规则来调度可用的TX子帧中的反馈报告(FR),指示反馈报告在可用的TX上均匀分布或分布 子帧。 以这种方式,可以减少TX子帧中的反馈报告的数量。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a method that enhances coverage for a mobile terminal on a power limit by retransmitting information related to one hybrid-automatic repeat request (HARQ) from a mobile terminal to a base station.SOLUTION: A mobile communication network supports two HARQ operation modes, and a first HARQ operation mode uses one TTI for transmission and retransmission. A mobile terminal uses a first prescribed number of TTIs including a first TTI and a second TTI to transmit information related to a first HARQ process to a radio base station by a second HARQ operation mode. When the mobile terminal receives an indication indicating that the transmission information was not correctly decoded at the radio base station, it uses a second prescribed number of TTIs to retransmit the information related to the first HARQ process by the second HARQ operation mode. The retransmission starts at the time of appearance of secondly available retransmission in the case of the first HARQ operation mode after the first TTI.

    • PROBLEM TO BE SOLVED: To enhance coverage of a power-limited mobile terminal in a mobile communication network.SOLUTION: The mobile communication network supports at least two Hybrid Automatic Repeat Request (HARQ) operation modes. A first HARQ operation mode uses a single Transmission Time Interval (TTI) for transmissions and retransmissions, where timing relationships between the transmissions and retransmissions are pre-determined. A redundancy version of a first HARQ process is transmitted from a mobile terminal to a radio base station by a second HARQ operation mode, using a first predetermined number of TTIs comprising at least a first TTI and a second TTI (702). When an indication indicating that transmitted information has not been decoded correctly at the radio base station is received (703), information relating to the first HARQ process is retransmitted by the second HARQ operation mode, using a second predetermined number of TTIs (704).
