摘要： Provided is a sequential transmission multi-beamforming apparatus and method with a low complexity based on a Hadamard matrix. A simple codebook may be generated based on the Hadamard matrix and thus, a number of weighted-vectors is reduced and a complexity of hardware is decreased. A diversity gain may be maximized based on a spatial diversity processing apparatus and a beamforming weighted vector may be systematically generated.

摘要： Disclosed herein are an apparatus and method for providing communication services. The apparatus includes a location information acquisition unit, a radio station information acquisition unit, and an offloading unit. The location information acquisition unit acquires information about the current location of the user terminal by sending a location information request message to the user terminal. The radio station information acquisition unit requests information about a white space radio station from which the user terminal can receive the communication services by sending the information about the current location of the user terminal to a white space server, and acquires, from the white space server, information about an available white space radio station. The offloading unit sends the information about the available white space radio station to the user terminal, and also sends information about the user terminal to the available white space radio station.
摘要翻译：这里公开了一种用于提供通信服务的装置和方法。该装置包括位置信息获取单元，无线电站信息获取单元和卸载单元。位置信息获取单元通过向用户终端发送位置信息请求消息来获取关于用户终端的当前位置的信息。无线电站信息获取单元通过向白空间服务器发送关于用户终端的当前位置的信息，请求有关用户终端可以从其接收通信服务的白空间无线站的信息，并且从白空间服务器，有关可用空白广播电台的信息。卸载单元向用户终端发送关于可用的空白无线电站的信息，并且将有关用户终端的信息发送到可用的空白无线电台。
