    • In the present invention, in a cellular communication system using frames (20) of communication resources in time and/or frequency domain, the communication resources (22) are divided into at least two regions (24, 26, 28). A first region (24) has a higher reuse in time and/or frequency domain than a second region (26, 28). The first region is a hybrid region (24), in which the communication resources individually are allocable for either uplink or downlink communication on a cell-to-cell basis. The second region is preferably a dedicated region (26), in which all communication resources have either uplink or downlink allocation. A third region (28) is preferably also present, in which all communication resources are allocated in the opposite direction to the second region (26). In preferred embodiments, the actual allocation of the hybrid region (24) is based on the traffic situation in each individual cell.
    • 在本发明中,在使用时域和/或频域的通信资源的帧(20)的蜂窝通信系统中,通信资源(22)被划分为至少两个区域(24,26,28)。 第一区域(24)在时间和/或频域上具有比第二区域(26,28)更高的再利用。 第一区域是混合区域(24),其中通信资源可单独地在基于小区的基础上分配用于上行链路或下行链路通信。 第二区域优选地是专用区域(26),其中所有通信资源具有上行链路或下行链路分配。 优选地还存在第三区域(28),其中所有通信资源被分配在与第二区域(26)相反的方向上。 在优选实施例中,混合区域(24)的实际分配基于每个单独小区中的业务情况。

    • 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.
