    • The present invention relates to receiving access signals from a plurality of terminals over a radio channel and in particular to determining a detection threshold level on the radio channel. A detection threshold level should balance the risk of missed detections to the risk of false detections. A problem in finding an equilibrium threshold is the radio environment, with noise and interference, change and then also the radio false detections or missed detections change. According to the present invention some access signals can be identified as being not assigned and therefore not being in use, and any detection of a non-used signal is identified as a false detection. By monitoring the ratio of false detections vs. correct detections the threshold level for detection is tuned into an equilibrium level, and that is adapted to the changing radio environments. In addition the detection threshold level for access signals detection threshold for data and/or control signalling may be adjusted in relation to the access signal threshold level.
    • 本发明涉及通过无线电信道从多个终端接收接入信号,特别涉及确定无线电信道上的检测阈值电平。 检测阈值水平应将错误检测的风险与错误检测的风险进行平衡。 找到平衡阈值的一个问题是无线电环境,噪声和干扰,变化,然后无线电错误检测或错过检测变化。 根据本发明,一些接入信号可以被识别为未被分配,因此不被使用,并且未使用的信号的任何检测被识别为错误检测。 通过监测错误检测与正确检测的比率,检测阈值水平被调整到一个均衡水平,并适应不断变化的无线电环境。 此外,可以相对于接入信号阈值电平来调整用于数据和/或控制信令的接入信号检测阈值的检测阈值电平。

    • A method and a base station (900) for controlling wireless communication of data on a first radio link between the base station and a User Equipment, UE (902), when a first communication Mode is employed implying that corresponding status reports should be transmitted on an opposite second radio link to indicate whether said data has been received or not. A communication unit (900a) communicates data and status reports with the UE according to the first communication Mode and according to a second communication Mode. When an indication of potential congestion pertaining to the second radio link is detected, a logic unit (900b) instruct the communication unit to trigger or initiate a change to a second communication Mode implying that no transmission of status reports on the second radio link is expected. Thereby, any unnecessary re-transmissions of data due to missing status reports may be avoided.
    • 一种用于在采用第一通信模式时基站和用户设备(902)之间的第一无线电链路上的数据的无线通信的方法和基站(900),这意味着相应的状态报告应该被发送到 相反的第二无线电链路,用于指示是否已经接收到所述数据。 通信单元(900a)根据第一通信模式和根据第二通信模式与UE通信数据和状态报告。 当检测到与第二无线电链路相关的潜在拥挤的指示时,逻辑单元(900b)指示通信单元触发或发起对第二通信模式的改变,这意味着在第二无线电链路上不传送状态报告 。 因此,可以避免由于缺少状态报告而导致的数据的不必要的重传。
