    • An arrangement (17) is provided for setting and adjusting at least one parameter in a radio communication network (11), which is used in control of communication in the radio communication network and which is dependent on a round trip time for a signal travelling from a radio network controller (13) to a user equipment (16) and back to the radio network controller. The arrangement comprises a module (17a) for initially estimating a maximum value of the round trip time; a setting module (17b) for initially setting the parameter depending on the initially estimated maximum value of the round trip time; a module (17c) for measuring the round trip time; and a module (17d) for adjusting the parameter depending on the measured round trip time, wherein the measured round trip time is expected to be shorter than the initially estimated maximum value of the round trip time.

    • A radio base station (1) for use in a wireless communication system comprises—a scheduling unit (9) arranged to schedule at least one user terminal to which to transmit in each subframe and—a power allocation unit (11) arranged to allocate a first amount of power to be used for the at least one user terminal in each subframe, a transmitter (5) arranged to transmit a transport block in a subframe to a number of user terminals (3) in the wireless” communication system in accordance with said scheduling and power allocation. The radio base station further comprises—a correction unit (15) arranged to determine, after scheduling has been performed for a chosen subframe, if there is excess power in the chosen subframe that has not been allocated to any user terminal and if so allocate at least a first part of the excess power to at least one user terminal scheduled in the subframe. The excess power is used when transmitting in the subframe.

    • The invention deals with the adjustment of the nominal target error rate for transmission of data from a priority queue to a new predetermined target error rate depending on the state of the priority queue. Usually, the adjustment to the new predetermined target error rate will be to a predefined lower target error rate based on states of the priority queue, such as amount of data in the priority queue, time passed since the latest transmission of data from the priority queue, whether the amount of data in the priority queue will fit into one transport block, whether the data unit to be transmitted for the priority queue is the first or last data unit in the priority queue and may also be based on the type of data stored in the priority queue. There may be more than one such priority queue.
    • 本发明涉及根据优先级队列的状态来调整数据从优先级队列传输到新的预定目标错误率的标称目标错误率。 通常,基于优先级队列的状态(例如优先级队列中的数据量),从优先级队列的最新数据传输以来经过的时间,对新的预定目标错误率的调整将是预定义的较低目标错误率 无论优先级队列中的数据量是否适合一个传输块,优先级队列中要发送的数据单元是否是优先级队列中的第一个或最后一个数据单元,还可以基于存储的数据类型 在优先级队列中。 可能有多个这样的优先级队列。

    • Communication efficiency may be enhanced by using compressed headers. In an example embodiment, a method is performed by a transmitting device to reduce header size. A mapping is created between a logical channel identifier and a compressed logical channel identifier. The compressed logical channel identifier occupies fewer bits than the logical channel identifier. The mapping is transmitted to a receiving device. A compressed header that includes the compressed logical channel identifier is formulated. A communication that includes the compressed header is transmitted to the receiving device. In another example embodiment, a method is performed by a receiving device to decode a header having a reduced size. A mapping and a communication including a compressed header are received. A compressed logical channel identifier is extracted from the compressed header. A logical channel identifier is recovered from the compressed logical channel identifier using the mapping.
    • 通过使用压缩头可以提高通信效率。 在示例实施例中,由发送设备执行一种方法来减少报头大小。 在逻辑信道标识符和压缩的逻辑信道标识符之间创建映射。 压缩的逻辑信道标识符占用比逻辑信道标识符少的位。 映射被发送到接收设备。 制定包括压缩逻辑信道标识符的压缩报头。 包括压缩报头的通信被传送到接收设备。 在另一示例实施例中,由接收设备执行一种方法来对具有减小的尺寸的报头进行解码。 接收包括压缩报头的映射和通信。 从压缩报头中提取压缩的逻辑信道标识符。 使用映射从压缩逻辑信道标识符恢复逻辑信道标识符。
