    • The present invention relates to methods and arrangements for improving the capabilities of an evolved Universal Terrestrial Radio Access Network, in particular for cases when more than one radio access network applying a time-division duplex transmission mode need to co-exist on a same carrier. The invention addresses further problems concerning an efficient allocation of uplink resources and resource allocation in a handover situation. The present invention assigns an attribute in form of a distinguishing value to the time slots used for the uplink and downlink transmission on said carrier such as to avoid scheduling of transmissions via a first radio access network in downlink or uplink time slots assigned to the second radio access network and to avoid scheduling of transmissions via the second radio access network in uplink time slots assigned for transmissions in the first radio access network.
    • 本发明涉及用于改进演进的通用陆地无线电接入网络的能力的方法和装置,特别是在应用时分双工传输模式的多于一个无线电接入网络需要共同存在于相同载波上的情况下。 本发明解决了在切换情况下有效分配上行链路资源和资源分配的问题。 本发明以对于所述载波上的上行链路和下行链路传输的时隙为特征值分配属性,以避免在分配给第二无线电的下行链路或上行链路时隙中经由第一无线电接入网络调度传输 并且避免在分配给第一无线电接入网络中的传输的上行链路时隙中经由第二无线电接入网络调度传输。

    • The invention is directed towards determining whether a hard handover should be performed of a mobile station (48) in relation to a first group of cells (16, 18, 20, 24) including a number of active cells (16, 18, 20) and handled by a first cell handling device (10) to a second group of cells (32, 36, 38) handled by a second cell handling device (26), when the cell handling devices lack a direct communication link (lur). Either the first cell handling device or the mobile station obtains measurements of link quality between the mobile station and cells of the groups, determines a first and second total quality factor for the groups, performs an evaluation of a preferred group involving comparing the first total quality factor with the second quality factor and initiates a handover from the first group to the second group if the second group is preferred.
    • 本发明旨在确定是否应当对包括多个活动小区(16,18,20)的第一组小区(16,18,20,24)进行移动台(48)的硬切换, 并且当小区处理设备缺少直接通信链路(lur)时,由第一小区处理设备(10)处理到由第二小区处理设备(26)处理的第二小区(32,36,38)。 第一小区处理装置或移动站都获得移动站与小区的小区之间的链路质量的测量,确定组的第一和第二总质量因子,执行优选组的评估,其包括比较第一总质量 并且如果第二组是优选的,则启动从第一组到第二组的切换。

    • A fan unit comprises a housing, which possesses a first housing wall having an air inlet, and an opposite parallel second housing wall having an air outlet, and a side wall arrangement connecting the first housing wall with the second housing wall. A holding plate is arranged between the first housing wall and the second housing wall adjacent to the air inlet for a suction blower drawing air from the air inlet and having a blower motor, said blower impeller being arranged between the air inlet and the holding plate, said blower impeller being adapted to blow drawn in air radially outward. The area of the holding plate is at least twice as large as the area of the air inlet and the holding plate together with the first housing wall constitutes a diffusor for the radially emerging blower air. This improves the efficiency of the fan unit and an increase in pressure is achieved which makes possible a reduction in the speed of rotation.
    • 风扇单元包括壳体,其具有具有空气入口的第一壳体壁和具有空气出口的相对的平行的第二壳体壁,以及将第一壳体壁与第二壳体壁连接的侧壁结构。 保持板布置在与空气入口相邻的第一壳体壁和第二壳体壁之间,用于抽吸风机从空气入口抽吸空气并具有鼓风机电动机,所述鼓风机叶轮布置在进气口和保持板之间, 所述鼓风机叶轮适于在径向向外的空气中吹送。 保持板的面积至少是空气入口面积的两倍,并且保持板与第一壳体壁一起构成用于径向排出的鼓风机空气的扩散器。 这提高了风扇单元的效率,并且实现了压力的增加,这使得可以降低旋转速度。
