    • A cellular mobile communication system comprises: a terminal which obtains C-port information from a base station by attempting an initial access, selects distributed antennas for D-port information after having transmitted an SRS, and communicates with said base station through said selected distributed antennas and a central antenna; and the base station which transmits the C-port information disposed in the center of a cell during the attempt of the initial access of said terminal, indicates the terminal to transmit the SRS, receives said SRS through the central antenna and distributed antennas, which are distributed within the cell and transmit and receive data with the terminal in some areas of the cell service areas, selects at least one distributed antenna by analyzing said SRS, notifies the terminal of the D-port information of said selected distributed antennas, and communicates with said terminal through said selected distributed antennas and the central antenna. Compared with a CAS, a distributed antenna system (DAS) of the cellular mobile communication system is capable of providing an enhanced mobile communication service by uniformly distributing antennas to service areas of a cell. The invention provides many kinds of DM-RS sequences in a distributed antenna system (DAS), in which antennas operated by each base station are distributed to service areas of the corresponding base stations of a cellular mobile communication system in which the plurality of the base stations exist, thereby easily distinguishing DM-RSs of various terminals which operate in the same RB. Thus, the invention maximizes the use of RS resources in the DAS. Therefore, according to an embodiment of the present invention, the cellular mobile communication system enables the DM-RSs to be efficiently generated and transmitted through antennas arranged in the center and the vicinity of a cell, whereby data is transmitted and received to and from each terminal at a high data rate regardless of the position of the terminals located within the cell.
    • 蜂窝移动通信系统包括:通过尝试初始接入从基站获取C端口信息的终端,在发送SRS之后选择D端口信息的分布式天线,并通过所选择的分布式天线与所述基站进行通信 和中心天线; 并且在所述终端的初始接入尝试期间发送设置在小区中心的C端口信息的基站指示发送SRS的终端,通过中心天线和分布式天线接收所述SRS, 分配在小区内并且在小区业务区域的一些区域中与终端发送和接收数据,通过分析所述SRS来选择至少一个分布式天线,向终端通知所选择的分布式天线的D端口信息,并与 所述终端通过所述选定的分布式天线和中央天线。 与CAS相比,蜂窝移动通信系统的分布式天线系统(DAS)能够通过将天线均匀地分配到小区的服务区域来提供增强的移动通信服务。 本发明在分布式天线系统(DAS)中提供多种DM-RS序列,其中由每个基站操作的天线被分配到蜂窝移动通信系统的相应基站的服务区域,其中多个基站 存在站,从而容易地区分在相同RB中操作的各种终端的DM-RS。 因此,本发明使DAS中RS资源的使用最大化。 因此,根据本发明的实施例,蜂窝移动通信系统能够通过设置在小区的中心和附近的天线有效地生成和发送DM-RS,从而从每个小区发送和接收数据 终端以高数据速率,而不管位于小区内的终端的位置。

    • A communication resource allocation method for solving resource request imbalance content in a cell is provided. Considering a propagation environment, the base station allocates a whispering resource to a whispering area, the whispering resource being one part of the communication resource and the whispering area being a peripheral area of the first base station, and allocates a speaking resource to a speaking area, the speaking resource being other parts of the communication resource and the speaking area being a border area of a cell. When the resource request of the whispering area is increased, the base station further allocates a part of the speaking resource to the whispering area or increases a ratio of the whispering resource. When the resource request of the speaking area is increased, the base station controls a threshold value for identifying the whispering and speaking areas or increases a ratio of the speaking resource.
