    • Disclosed is a method for establishing a CoMP cooperating set in coordinated multi-point communication, the method comprising the steps of: triggering and starting a coordinated multi-point communication process; according to channel state information of all cells in a measurement cell set measured by a UE, determining a candidate CoMP cooperating set; sending a CoMP cooperating set establishment request to eNodeBs of the cooperating cells in the determined candidate CoMP cooperating set; the eNodeBs being of the cooperating cell and receiving the CoMP cooperating set establishment request responding to the CoMP cooperating set establishment request to the eNodeB of the serving cell of the UE, and sending a CoMP cooperating set establishment response to the eNodeB of the serving cell of the UE; the eNodeB of the serving cell of the UE determining a CoMP cooperating set of the UE according to information of the CoMP cooperating set establishment response; and according to a coordinated multi-point communication mode, sharing data information and service bearer information of the UE of the CoMP cooperating set. The present invention guarantees coordinated multi-point joint transmission/reception, decreases the overhead and complexity of the communication system and furthermore reduces the time delay in the information exchange.
    • 公开了一种在协调多点通信中建立CoMP协作集的方法,所述方法包括以下步骤:触发并启动协调的多点通信过程; 根据由UE测量的测量小区集中的所有小区的信道状态信息,确定候选的CoMP协作组; 向确定的候选CoMP协作集中的协作小区的eNodeB发送CoMP协作组建立请求; 所述eNodeB是协作小区,并且将响应于所述CoMP协作组建立请求的所述CoMP协作组建立请求接收到所述UE的所述服务小区的eNodeB,并且向所述服务小区的eNodeB发送CoMP协作集合建立响应 UE; UE的服务小区的eNodeB根据CoMP合作组建立响应的信息确定UE的CoMP协作组; 并且根据协调的多点通信模式,共享CoMP协作组的UE的数据信息和业务承载信息。 本发明保证了协调的多点联合发送/接收,降低了通信系统的开销和复杂性,进而减少了信息交换中的时延。

    • Systems, devices, features, and methods for detecting common geographic features in images, such as, for example, to develop a navigation database are disclosed. For example, a method of detecting a common text pattern, such as for a road or path sign, from collected images includes collecting a plurality of images of geographic areas along a road or path. An image of the plurality of images is selected. Components that correspond to an object about the road or path in the selected image are determined. In one embodiment, the determined components are independent or invariant to scale of the object. The determined components are compared to reference components in a data library. If the determined components substantially match the reference components, the object in the selected image is identified to be a common pattern, such as for a standard road or path sign, corresponding to the reference components in the data library.
    • 公开了用于检测图像中的常见地理特征的系统,设备,特征和方法,例如开发导航数据库。 例如,从收集的图像中检测公共文本图案(例如道路或路径符号)的方法包括沿着道路或路径收集多个地理区域的图像。 选择多个图像的图像。 确定对应于所选图像中的道路或路径的对象的组件。 在一个实施例中,所确定的分量对象的尺度是独立的或不变的。 将确定的组件与数据库中的参考组件进行比较。 如果确定的分量基本上与参考分量相匹配,则所选图像中的对象被识别为对应于数据库中的参考分量的公共模式,例如用于标准道路或路标。
