Abstract: The present invention relates to a method, in a base station of a MTC based communication system, of configuring bandwidth for a MTC user equipment, wherein bandwidth of the MTC user equipment is smaller than system bandwidth for MTC, the method comprising the steps of: receiving a first message from the MTC user equipment, the first message indicating an offset of bandwidth selected by the MTC user equipment according to a predetermined selection policy relative to the system bandwidth, wherein the selected bandwidth covers center frequency band of the system bandwidth; determining the bandwidth selected by the MTC user equipment according to the first message. According to the invention, the system bandwidth for MTC and the bandwidth of the MTC user equipments can be asymmetrically increased, while extending the capacity of MTC by allocating wider bandwidth. The cost for the user equipments in a MTC based communication system could be saved by reserving the bandwidth of the MTC user equipments or by reducing the increment of the bandwidth of the MTC user equipments while increasing the system bandwidth for MTC.
Abstract translation: 本发明涉及一种在基于MTC的通信系统的基站中为MTC用户设备配置带宽的方法，其中所述MTC用户设备的带宽小于MTC的系统带宽，所述方法包括以下步骤： 从所述MTC用户设备接收到第一消息，所述第一消息指示所述MTC用户设备根据相对于系统带宽的预定选择策略选择的带宽的偏移，其中所选择的带宽覆盖所述系统带宽的中心频带; 根据第一消息确定MTC用户设备选择的带宽。 根据本发明，通过分配更宽的带宽来扩展MTC的容量，可以不对称地增加用于MTC的系统带宽和MTC用户设备的带宽。 可以通过保留MTC用户设备的带宽或通过减少MTC用户设备的带宽的增加同时增加MTC的系统带宽来节省用于MTC的通信系统中的用户设备的成本。
