Abstract

A networking system for indoor coverage of time division duplex synchronous system is provided in the present invention, which comprises a Base Band Unit (BBU), multiple Remote Radio Units (RRUs), and multiple ceiling antennas, wherein, the BBU connects with the RRU through a fiber interface. Each RRU has two independent channels. Each independent channel at least comprises a fiber interface, a digital intermediate frequency unit, a transceiver, a power amplifier/low noise amplifier and a filter which are connected in turn. Each independent channel also solely connects with some ceiling antennas. Compared with the existing single channel coverage, the dual channels coverage of the present invention have diversity gain because two channels are independent in space, and the solution of the present invention which performs a partitional coverage for indoor area enhances the capacity of the indoor system, it is especially adaptive for an application in large supermarket, exhibition centre or stadium. A verification for the present invention shows that the solution can greatly promotes the system capacity, and the promoted quantity approaches 100%.

現有 木相比， 本 明通 引 通道， 室內 覆蓋， 減 少了室外 室內用戶的 ， 提高了室內 統容量， 特別 合于大型 超市、 展中 或者休 的 。 說明 Compared with the existing wood, this guide channel, indoor coverage, reduce the outdoor indoor users, improve the indoor system capacity, especially in large supermarkets, exhibitions or leisure. Description
1力本 室內覆蓋 統 的 的示意 1 Illustrator of the indoor coverage system
2力本 小 的 的示意  2
休 方式 Hugh way
下面結合 和 休 方式 本 步說明。 The following is a description of this step in conjunction with the Hugh mode.
1力本 室內覆蓋 統 的 的示意 ， 1所示， 本 提出的組 統方案 +RR 的方式 完成室內覆蓋， 和RR 的 及其連接 1所示， 者 仟連接， 以減少可能出現 的大量 ， 本 的 統至少包括以下 部分  1 shows the indication of the indoor coverage system, 1 shows that the proposed unit scheme + RR completes the indoor coverage, and the RR and its connection 1 are shown, and the connection is made to reduce the large number of possible The system includes at least the following parts
羊 ( ) 的 中至少 GPS接收 、 主控/ 羊 、 以及光仟接口 部分 射頻 (RR )至少包括 仟接口、 中 羊 、 信札、 功率 大器/低噪音 大器及濾波器。要求RR 2 (即 通道) 或者多端 及 頂天 若干。 At least GPS receiver, master/sheep, and optical interface part of the sheep ( ) The radio frequency (RR) includes at least a 仟 interface, a medium sheep, a letter, a power amplifier/low noise generator, and a filter. Require RR 2 (ie channel) or multi-end and top-of-the-day.
本 的 方案， 近可以 步包括合井羊 ( ， 因 1中未 ) ， 于在上行接收 ， 將 由 仟接口接收到的、 RR 的 通道的信 行合井， 然 再由 執 行 。合井羊 可 RR 通道的信 強弱而 等增益 合井、 合井或最大比合井。  In this scheme, it is possible to include the well-in-law (in the case of 1), and to receive the uplink, and the signal of the RR channel received by the 仟 interface is merged, and then executed. Hejing Yang can be the strength of the RR channel and the equal gain, well, well or maximum ratio.
相虛的， 近可以 步包括 羊 ( ， 因 1中未 )， 于在下行 ， 在所 RR 的 通道中 介最 通 道作力下行 通道。 羊 可以 RR 通道的上行接 收功率大小東 最 通道。  In the case of imaginary, it is possible to include the sheep (1, because 1 is not), and in the downward direction, the most channel in the RR channel is the downward channel. The sheep can receive the uplink power of the RR channel and the east channel.
本 的 ， 在室內建立同 小 覆蓋， 同 小 的 2 所示。 可 室內覆蓋 ， 小 私有 ， 小 分布可依 。 RR 介小 ， 小 內由 通道覆 蓋。 室內同 ， 室內 用的 室外 不同。 小 內  This is the same as the small 2 in the room. Can be indoor coverage, small private, small distribution can be relied upon. The RR is small and the small inside is covered by the passage. Indoors are the same as indoors. Small inside
通道連接的 頂天 置， 形成空同 的效果。  The top of the channel connection creates an empty effect.
在 2中， 的 S， 則分割 的矩形 s， 5s/3。 在 頂天 布置 ， 可 是在 方形 ， 方形的 a s。 方形 3所示。  In 2, the S is divided into rectangles s, 5s/3. Arranged in the top, but in a square, square a s. Square 3 is shown.
小 介RR ， RR 有 的通道，在理想的情況 下， 的通道 3所示連接4 頂天 ， 其中圓形 通道 頂天 ， 星形 另 通道 頂天 。 3 所示 頂天 的布置， 羊 小 或者 看， 頂天 都是均勻的。  There are channels of RR, RR, and in the ideal case, channel 3 is connected to 4 days, where the circular channel is topped, and the star is connected to the sky. 3 The arrangement of the top of the sky, the sheep are small or look, the sky is even.
本 的 方案， 量保 通道中 于不同通道的 頂天 的 大于 波長的 10倍。 通道中 頂天 力分 置， 且 均勻分布。 The solution of the volume assurance channel in different channels The top of the sky is 10 times larger than the wavelength. The top force in the channel is divided and evenly distributed.
在 通道上行接收 ， 通道 頂天 接收的信 是 的， 在 RR 中 到中 ， 接口 中合井。各通道接收功率等于 通道的所有 頂天 接收功率 和， 通道 將 到 行 合井。 了減小 理的 ， 通道的信 通道 的強弱比較而 等增益合井、 合井或者最大比合井。  In the uplink receiving of the channel, the letter received by the channel in the sky is yes, in the RR to the middle, the interface is well. The received power of each channel is equal to all the top-day received power of the channel, and the channel will go to the well. To reduce the rationality, the strength of the channel's signal channel is compared with the equal gain well, the well or the maximum ratio.
在 通道下行 ， 上行 通道接收到的功率， 接收功率 最大的那 通道作力下行 通道， 因此， 始終是 最 的通道  In the downlink of the channel, the power received by the uplink channel and the channel with the largest receiving power act as the downlink channel, so it is always the most channel.
。  .
用本 的 通道覆蓋 現有的羊通道覆蓋相比， 由于 通道在 同上是 的， 存在 增益， 因此， 大幅度提高了 統容量。 本 所做的 表明， 可以 統的容量有較大提升， 提升 接近 %  Compared with the existing sheep channel coverage with this channel, since the channel is the same as above, there is gain, and therefore, the system capacity is greatly improved. This shows that the capacity of the system can be greatly improved, and the improvement is close to %.
以上 ， 力本 較佳的 休 方式， 但本 的保  Above, the best way to rest, but the protection of this
不局限于此， 任何熟悉 木的 在本 揭露的 木 園內， 可輕易 想到的 或替換， 都 涵蓋在本 的保 內。 因此， 本 的 保 以 要求的保 固 。 Not limited to this, any wood that is familiar to the wood can be easily conceived or replaced in the wood garden disclosed herein. Therefore, this warranty is required to be guaranteed.
