    • Embodiments herein relate to a method in a radio base station (12) for providing radio coverage to a user equipment (10). The radio base station (12) comprises at least two radio antenna ports; a first antenna port (AP11) associated with a first physical antenna and a second antenna port (AP12) associated with a second physical antenna. The first antenna port (AP11) is arranged to provide a radio coverage over a first area (14) and the second antenna port (AP12) is arranged to provide a radio coverage over a second area (17). The radio base station (12) broadcasts a signal with system information over the first area (14) enabling the radio base station (12) to connect to the user equipment (10). The radio base station (12) also determines that a user equipment (10) in the first area (14) is to receive or transmit data. The radio base station (12) then obtains information related to a position of the user equipment (10) in the first area (14). The radio base station (12) then sets a characteristic of the second physical antenna based on the obtained information. Thereby to the radio base station provides radio coverage to the user equipment (10) via the second port (AP12).
    • 本文的实施例涉及用于向用户设备(10)提供无线电覆盖的无线电基站(12)中的方法。 无线电基站(12)包括至少两个无线电天线端口; 与第一物理天线相关联的第一天线端口(AP11)和与第二物理天线相关联的第二天线端口(AP12)。 第一天线端口(AP11)被布置成在第一区域(14)上提供无线电覆盖,并且第二天线端口(AP12)被布置成在第二区域(17)上提供无线电覆盖。 无线电基站(12)通过第一区域(14)广播具有系统信息的信号,使得无线电基站(12)能够连接到用户设备(10)。 无线电基站(12)还确定第一区域(14)中的用户设备(10)要接收或发送数据。 然后,无线基站(12)获取与第一区域(14)中的用户装置(10)的位置有关的信息。 然后,无线基站(12)基于获得的信息设定第二物理天线的特性。 由此,无线基站经由第二端口(AP12)向用户设备(10)提供无线覆盖。
