    • In a packet transmission method, an error protection mechanism for HARQ feedback jointly codes successive acknowledgement messages to improve reliability. Successive acknowledgement messages are channel encoded into feedback signals using a convolutional code with rate k/m (see e.g. Lin & Costello Error Control Coding Prentice Hall 1983). With convolutional codes one input block of k information bits arrives per epoch and is coded into an output block of m>k coded bits. The coded signal at the current epoch depends on the input at the current epoch and the λ-1 previous input blocks (λ is called the code constraint length).The decoder introduces a delay when decoding HARQ acknowledgements messages but this delay is more than compensated the improved performance and the elimination of the large delays due to NACK to ACK errors.
    • 在分组传输方法中,用于HARQ反馈的错误保护机制对连续的确认消息进行联合编码以提高可靠性。 使用速率为k / m的卷积码将连续的确认消息信道编码为反馈信号(参见例如Lin& Costello Error Control Coding Prentice Hall 1983)。 利用卷积码,一个k个信息比特的输入块到达每个历元并且被编码成m×k个编码比特的输出块。 当前时期的编码信号取决于当前历元和λ-1个先前输入块的输入(λ称为码约束长度)。解码器在解码HARQ确认消息时引入了延迟,但是该延迟不仅被补偿 改进的性能以及消除由NACK至ACK错误造成的大延迟。

    • An infrastructure equipment of a wireless communications network is configured to transmit signals to one or more communications devices via a wireless access interface, and to receive signals from one or more of the communications devices via the wireless access interface. The wireless access interface provides communications resources arranged in time divided units of a carrier frequency bandwidth providing a plurality of blocks of communications resources, each of the time divided units comprising on a downlink of the wireless access interface a control channel for transmitting control channel messages and a shared channel, the control channel message allocating communications resources of the shared channel to the communications devices to receive the signals from the one or more infrastructure equipment. The infrastructure equipment is configured to transmit data, as a plurality of data units, to the one or more communications devices, each data unit being encoded for transmission in accordance with a repeat request-type process, the encoding providing an indication of whether the data has been received correctly by a communications device. Each of the data units is transmitted in one of a repeating number of consecutive time divided units according to a separately controlled repeat request-type process. The transmitter is configured to transmit a control message allocating resources of the shared channel for receiving a data unit of a repeat request-type process which is one or more time divided units after a time divided unit in which the control message is transmitted, and the number of repeat request-type processes in the repeating pattern of time divided units is increased from a first number in the first mode to a second number in the second mode.
