摘要： A method for determining a precoding matrix indicator, user equipment, and a base station are disclosed in embodiments of the present invention. The method includes: receiving a first reference signal set sent by a base station, where the first reference signal set is associated with a user equipment-specific matrix or matrix set; selecting a precoding matrix based on the first reference signal set, where the precoding matrix is a function of the user equipment-specific matrix or matrix set; and sending a precoding matrix indicator to the base station, where the precoding matrix indicator corresponds to the selected precoding matrix. In the embodiments of the present invention, CSI feedback precision can be improved without excessively increasing feedback overhead, thereby improving system performance.

摘要： The present invention relates to the field of the mobile communications technologies, and in particular, to a wireless transmission path selection method and apparatus. In this solution, according to corresponding precoding information, a CQI of each wireless transmission path and/or orthogonality information of channel propagation directions from any two candidate transmission nodes in a candidate transmission node set to a wireless transmission path selection node are/is determined. Both the precoding information and the orthogonality information of the channel propagation directions are related to spatial beamforming. Therefore, interference imposed by spatial beamforming on a signal is considered during wireless transmission path selection, improving accuracy of a determined wireless transmission path, and improving capacity resource utilization.

摘要： A method and an apparatus for providing a service to a user are provided. The method mainly includes that a mobile communication system on a network side receives call information of calling a mobile terminal of a user and then calls the user according to stored location information corresponding to the mobile terminal of the user sent by an access gateway AG. The AP is deployed at the enterprise to implement accurate positioning of a user that enters or leaves an office of an enterprise and update to a mobile communication system on a network side through the AG in real time. Therefore, the accurate positioning of a mobile terminal of a user no longer has to rely on the network coverage of the PLMN.
摘要翻译： 提供了一种用于向用户提供服务的方法和装置。 该方法主要包括：网络侧的移动通信系统接收到呼叫用户的移动终端的呼叫信息，然后根据与接入网关AG发送的用户的移动终端对应的存储的位置信息来呼叫用户。 AP部署在企业中，以实现进入或离开企业办公室的用户的准确定位，并通过AG实时更新到网络侧的移动通信系统。 因此，用户的移动终端的准确定位不再依赖于PLMN的网络覆盖。
