Generally, the non-user-specific control information includes information required to decode user specific control information, where the user-specific control information is information indicating a specific user or a specific user group, and usually includes Assignment Advanced-MAP, Power Control Advanced-MAP, Hybrid Automatic Repeat Request (HARQ) feedback information ( HARQ Feedback Advanced-MAP), etc. In practical applications of TDD or FDD wireless communication systems using OFDMA technology, Fractional Frequency Reuse (FFR) technology is usually used. Figure 1 indicates an implementation of a partial frequency reuse technique.

In order to further understand the foregoing technical solutions provided by the embodiments of the present invention, the method for transmitting the foregoing control information provided by the embodiments of the present invention is described in detail below through specific embodiments. In the following embodiments, an IEEE 802.16m system is taken as an example to describe the technical solution provided by the embodiment of the present invention. FIG. 2 is a schematic diagram of a frame structure of IEEE 802.16m. As shown in FIG. 2, the entire radio resource is divided into super Different structure granularities such as frames, frames, subframes, and OFDM symbols. Specifically, the radio resource may be first divided into time-continuous super frames, each superframe has a duration of 20 milliseconds, and each superframe consists of four frames of 5 milliseconds and a length of time (Frame). Composition, each frame contains 8 subframes (SF), and each subframe is composed of 6 OFDM symbols. In the following embodiments, the frequency resource allocation manner of the adjacent three cells is as shown in FIG. 3, and all available downlink frequency resources are divided into four frequency sets ^: [^'^'^' ^ ²³ ] , where ,

^'^'^构成的频率重用区域的频率重用因子为 1/3 , 即 ^'^'^中的频率资源分配给三个相邻小区中一个小区，而其他两个小区则不能使用该频率资源或者需要釆用限制其发射功率的方法来使用该频率资源； ^²³构成的频率重用区域的频率重用因子为 1 , 即三个相邻小区都可以不加限制的使用该频率资源，称 ^²³构成的频率重用区域的 Reuse Factor = 1。从图 3可以看出，每个小区中不同频率集合由于千扰级别的不同导致其下行覆盖范围不一样，对小区 A, 频率集合 ^上的下行千扰级别最小，覆盖范围最大，对小区 B , 频率集合 ^的下行千扰级别最小，覆盖范围最大，对小区 C, 频率集合 ^的千扰级别最小，覆盖范围最大。实施例一该实施例以图 2所示的帧结构以及图 3所示的频率资源分配方式为例，对图 3中的小区 A的基站（BS-A )传输非用户专有控制信息进行说明。图 4为本实施例的流程图，假设 BS-A需要在超帧的某个子帧上传输非用户专有控制信息，且该子帧的频率资源按照图 3所示划分成四个频率集合，形成两个频率重用区域（其频率重用因子分别为 1/3和 1 ), 其中频率重用因子为 1/3的频率重用区域包含三个频率集合，频率重用因子为 1的频率重用区域包含一个频率集合，如图 4所示， BS-A传输非用户专有控制信息主要包括以下步 4聚：步骤 401 , BS-A在该子帧中频率重用因子为 1/3的频率重用区域中的功率级别最高的频率集合 ^上通过广播方式发送非用户专有控制信息。步骤 402, 终端利用已知信息解码上述非用户专有控制信息，通过对这些信息的解析确定后续工作流程。在具体实施过程中， BS-A可以在 ^的部分或全部分布式逻辑资源块上传输非用户专有控制信息，在具体实施过程中，该分布式逻辑资源块可以是按标准缺省配置，也可以由 BS-A在辅广播信道中通知终端通过哪些分布式逻辑资源块发送；并且， BS-A 还可以 ^的除标准缺省配置分布式逻辑资源块以外的其它分布式逻辑资源块集合上传输非用户专有控制信息；另外， The frequency reuse factor of the frequency reuse region formed by ^'^'^ is 1/3, that is, the frequency resource in ^'^'^ is allocated to one of three adjacent cells, and the other two cells cannot use the frequency. The resource may need to use the method to limit its transmit power to use the frequency resource; ^ ²³ The frequency reuse region has a frequency reuse factor of 1, that is, three neighboring cells can use the frequency resource without restriction, called ^ ²³ Reuse Factor = 1 for the frequency reuse region. It can be seen from FIG. 3 that different frequency sets in each cell have different downlink coverage due to different interference levels. For cell A, the downlink interference level on the frequency set is the smallest, and the coverage is the largest, and the cell B is the largest. The frequency aggregation ^ has the smallest downlink interference level and the largest coverage. For the cell C, the frequency set ^ has the smallest interference level and the largest coverage.

Step 402: The terminal decodes the non-user-specific control information by using known information, and determines a subsequent workflow by analyzing the information. In a specific implementation process, the BS-A may transmit non-user-specific control information on part or all of the distributed logical resource blocks. In a specific implementation process, the distributed logical resource block may be configured according to a standard default. It is also possible for the BS-A to notify the terminal in which the distributed logical resource blocks are transmitted in the secondary broadcast channel; and, the BS-A can also set other distributed logical resource block sets other than the standard default configuration distributed logical resource block.

Non-user-specific control information is transmitted on the area. These cases are described separately below. The distributed logical resource block that notifies the terminal to transmit the non-user-specific control information through the secondary broadcast channel. In the frame structure shown in FIG. 5, the first subframe of each frame (ie, SF0) needs to transmit non-user-specific control information. Then, before step 401, the BS-A transmits, by using the secondary broadcast channel, a distributed logical resource block required to transmit non-user-specific control information on the frequency set having the highest power level in the frequency reuse region having the frequency reuse factor of 1/3 (Distributed).
