In the flow 3 in which the present embodiment of the present invention is the same as the suppression method of the present invention, the flow of the same method is the same as the suppression method of the present invention. Process 5 is the schematic of the small suppression of the shape of the present 6 is the present. In the way of considering the small suppression information in the wood, the suppression scheme of the small amount of the small suppression information is not small in the use of the terminal, and the performance of the improvement is small. Increase the capacity of the system. The resources are beneficial to the system because of the amount of information the terminal has. In addition, because of the information of the terminal itself, the reliability of the system is improved to a certain extent with the genre of the terminal. The following explanations of the following descriptions of the Ming and Qing dynasty are not used for the final version. It is used for the present small and small and terminal diagrams S and S2 respectively represent the phase of the small aseSa o S) S and S2 respectively represent the same terminal ob eS o S ). In the case of S, S is the small terminal S2 is the small terminal. In the case of S2, S2 is the small terminal S is the small terminal. In the case of S, S is smaller than S2, and S2 is smaller than S2. The method of the present invention proposes a method for suppressing the same method. 2 is the step S202 to the step S206 in the method package shown in the flow 2 of the method of the present invention.

The method of obtaining the information amount of the information in the terminal in step S402 is the same, that is, the method of indexing the S and S2 OA is the same. The method of indexing the quantity of the terminal is in this case, S and the common channel S S2 will be the same as the general channel S2, and S and S2 will interact with S2. The device was mentioned. 6 is the 6 of the present, 62 packs receive 4, 6, and shape 8 as described below. Receive 4 in the amount of information received from the terminal 64 6 to receive 4 in the amount of 4 received information to shape 8 to 6 in the root 6
未 小 同 的抑制。 在 收 4 收未自終端 64的量 信息 前 終端 64 的信 信息 信息 量 得到量 信息 向 量 信息。 其中 量 信息 以是 信息 第 是量 的 A 的 量 比特 第 是量 的 A 的量 在 量 同內 的索引 。 需要 的是 在終端向 量 信息 方法 以包 下操作 核基 向 的相 量 信息 或終端向 的相 量 信息。 休 終端向 量 信息 以是本小 終端同 將 信息 用的 分別 本小 和 小 同 小 終端 將 信息 用的 分別 本小 和 小 以是各小 終端 將 信息 用的 各小 而各小 的 小 和各小 本小 的交互 得 終端 本 的 信息。 其中 于終端 的量 信息是第 信息 量 的 OA 的量 比特 ) 收 4 收到量 比特 6 量 比特 的 OA 終端 的量 OA 再 No suppression of the same. The amount of information information of the terminal 64 is obtained by the amount of information of the information of the information of the terminal 64 before the amount information of the terminal 64 is received. The amount of information is the index of the amount of A of the amount A of the quantity that is the quantity of the information. What is needed is to operate the phasor information of the nucleus or the phasor information of the terminal in the terminal vector information method under the package. The rest terminal vector information is the small and small small terminal used by the small terminal and the small and small small terminal, and the information used by each small terminal is small and small. This small interaction has the information of the terminal. The amount information of the terminal is the amount of the OA of the information amount.) The amount of the OA terminal of the OB terminal of the received amount of the bit 6 is received.
于終端 的是第 信息 量 的 OA 的量 在 量 同內的索引 ) 接收 4 收到的是量 的 OA 的索引 則 6 索引 在 量 同內 的 OA  At the end of the terminal is the amount of OA of the amount of information in the same amount of index) Receive 4 Received is the amount of OA index then 6 Index in the same amount of OA
的量 OA 再 。 需要 的是 了 到抑制小 同 的目的 要求 的 主 方向 本小 終端 小 終端。 通 本 的 了 于有 的小 同 抑制方法。 在 方法中 利用終端 的有 的量 信息  The amount of OA again. What is needed is to suppress the small purpose of the main direction of the small terminal small terminal. The general method of suppression is based on the small suppression method. In the method, the amount of information of the terminal is utilized.
再 的 賦形 未抑制 相 小 的 到提高系 性能和增大系 容量的目的。 同 由于終端 有 的量 信息 了資源 有利于系 的 。 另外 由于終端 本身的信息 所以 以 跟 終端的文 情 在 定程 度 提高了系 的 靠性。 以 所述 力本 的 而已 不用于 制本 于本 域的 木 未 本 以有各 更 文 。 凡在本 的精神 原則 所 的 何修 、 等同替換、 等 包含在本 的保 內。 The re-formation does not inhibit the phase to be small to improve the performance of the system and increase the capacity of the system. The resources are beneficial to the system because of the amount of information the terminal has. In addition, because of the information of the terminal itself, the reliability of the system is improved to a certain extent with the genre of the terminal. The use of the above-mentioned force is not used to make the wood in this domain. All the repairs, equivalent replacements, etc. in the spiritual principles of this book are included in this warranty.
