摘要： A technique for communicating protocol data units, PDUs, in a radio communication from a transmitter (100) to a receiver (200) is described. As to a method aspect of the technique, one or more control messages indicative of Quality of Service, QoS, requirements for the radio communication are received. The QoS requirements include a control command for a reliability of the radio communication and a control command for a latency of the radio communication. A batch of redundant PDUs is transmitted from the transmitter (100) to the receiver (200). A number of the redundant PDUs per batch depends on the control command for the reliability and a temporal spread of the redundant PDUs per batch depends on the control command for the latency.

摘要： Method for accessing, by a communication device (200), a shared communication channel in which contention based access to the communication channel is used, by multiple devices with traffic of different priority. The communication device is configured to transmit data streams with different transmission priorities via the shared communication channel with a first data type stream having a higher transmission priority than a second data type stream. For each type of traffic, a different set of parameters are specified and applied during the contention access (clear channel assessment), this being related to the contention window (minimum ad maximum values), which allows to determine the waiting time before accessing the shared medium, as well as to the duration of the transmission time eventually granted. The method identifies various adjustments of these parameters. In principle, the time range for the first data type traffic is lower than the time range for the second data type traffic. In case second data transmissions takes place but a packet has only being transmitted partially, the maximum value of the corresponding time range is reduced. In other scenarios, in case of congestion of the shared medium, maximum time range values are increased. Further, parameters such as the minimum value of the time range or else the granted transmission window for the second data type traffic are adjusted according to the load and requirements associated to the first data type traffic.
摘要翻译：一种通过通信设备（200）访问由多个具有不同优先级的流量的设备使用对通信信道进行基于竞争的访问的共享通信信道的方法。通信设备被配置为经由共享通信信道以具有比第二数据类型流更高的传输优先级的第一数据类型流来发送具有不同传输优先级的数据流。对于每种类型的流量，在争用访问（清除信道评估）期间指定和应用不同的参数集合，这与争用窗口（最小广告最大值）相关，这允许在访问共享之前确定等待时间中等，以及最终授予传输时间的持续时间。该方法识别这些参数的各种调整。原则上，第一数据类型流量的时间范围低于第二数据类型流量的时间范围。在发生第二数据传输但分组仅部分传输的情况下，相应时间范围的最大值被减少。在其他情况下，在共享介质拥塞的情况下，增加最大时间范围值。此外，根据与第一数据类型业务相关联的负载和要求来调整诸如时间范围的最小值或第二数据类型业务的授权传输窗口之类的参数。
