Description

数据传输方法、 装置及无线帧 技术领域 本发明涉及通信领域， 具体而言， 涉及一种数据传输方法、 装置及无线帧。 背景技术 在以无线帧 （ Radio frame ) 为单位进行数据传输的无线系统中， 无线空口 传输的上 /下行链路一般是以 Radio frame为单位进行传输数据的； 其中， 每个 Radio frame由若千个子帧 （Subframe )组成， 并且， Subframe均以正交频分复 用（ Orthogonal Frequency Division Multiplexing, 简称为 OFDM )符号（ Symbol ) 为基本单位组成。 对于长期演进（Long-Term Evolution, 简称为 LTE ) 系统， 每个 Radio frame由 10个 Subframe组成。 目前的 LTE、 啟波接入全球互通 ( Worldwide Interoperability for Microwave Access,简称为 Wimax )、超级移动宽带（ Ultra Mobile Broadband,简称为 UMB ) 系统啫有两种双工方式： 频分双工 （ Frequency Division Duplex, 简称为 FDD ) 方式和时分双工 （ Time Division Duplex, 简称为 TDD ) 方式。 在 FDD方式下， 上 /下行链路釆用不同的频带进行数据传输， 这样， 系统 的上 /下行子帧 （Subframes ) 的资源分配相对比较独立， 即， 可以对下行子帧 ( Subframes ) 和上行子帧 （Subframes ) 分别进行资源分配。 在 TDD方式下， 由于上 /下行链路使用相同的频段分时进行传输， 这样， 根据业务的需要， 系统可以按照一定的比例将无线帧的若千子帧分成上行子帧 和下行子帧。 一般 TDD 系统上行子帧和下行子帧个数的比例都有若千种类， 以满足不同业务类型的需要。 根据不同地区业务类型的需要， 选择恰当的上下行比例配置有利于提高 TDD系统的频谱效率。 比如， 对于下载数据业务比较多的地区， 就可以选择下 行子帧比较多的配置； 对于上载数据业务比较多的地区， 就可以选择上行子帧 比较多的配置； 对于上下载数据业务量比较平衡的地区， 就可以选择上下行子 帧差不多相等的比例配置。 在目前的 LTE TDD (或称为 TD-LTE ) 系统中， 对 TDD上下行比例配置设定了 7种， 如下表 1所示。 一个无线帧包含了 10个子 帧，子帧号分别标记为： 0, 1,2,3,4,5,6,7,8,9。 "D"表示该子帧为下行子帧； "U" 表 示该子帧为上行子帧； "S"表示该子帧为特殊子帧， 即该子帧既包含有上行传 输的部分也包含有下行传输的部分。 表 1 上下行子帧配置表 TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a data transmission method, apparatus, and radio frame. BACKGROUND In a wireless system that performs data transmission in units of radio frames, uplink/downlinks of wireless air interface transmission generally transmit data in units of radio frames; wherein each radio frame is composed of thousands The sub-frames are composed of sub-frames, and the sub-frames are all composed of Orthogonal Frequency Division Multiplexing (OFDM) symbols. For the Long-Term Evolution (LTE) system, each Radio frame consists of 10 Subframes. The current LTE, Worldwide Interoperability for Microwave Access (Wimax), and Ultra Mobile Broadband (UMB) systems have two duplex modes: Frequency Division and Duplex (Frequency Division) Duplex, abbreviated as FDD) and Time Division Duplex (TDD). In the FDD mode, the uplink/downlink uses different frequency bands for data transmission. Thus, the resource allocation of the system's uplink/downlink subframes is relatively independent, that is, the downlink subframes (Subframes) and uplinks can be used. Subframes are used for resource allocation. In the TDD mode, the uplink/downlink uses the same frequency band for time-division transmission. Thus, according to the needs of the service, the system can divide the thousands of subframes of the radio frame into the uplink subframe and the downlink subframe according to a certain ratio. Generally, there are thousands of types of uplink subframes and downlink subframes in the TDD system to meet the needs of different service types. According to the needs of different regional business types, choosing the appropriate uplink-downlink ratio configuration is beneficial to improve the spectrum efficiency of the TDD system. For example, for an area with a large number of data download services, you can select a configuration with more downlink subframes. For an area with more data services, you can select a configuration with more uplink subframes. In the region, you can select a proportional configuration in which the uplink and downlink subframes are almost equal. In the current LTE TDD (or TD-LTE) system, seven types of TDD uplink and downlink proportion configurations are set, as shown in Table 1 below. A radio frame contains 10 subframes, and the subframe numbers are labeled as: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. "D" indicates that the subframe is a downlink subframe; the "U" table The subframe is shown as an uplink subframe; "S" indicates that the subframe is a special subframe, that is, the subframe includes both an uplink transmission and a downlink transmission.

相关技术中的数据传输方法， 对于釆用某一种配置的 TDD 系统区域， 当 该区域出现不同的业务类型需求时， 该区域就需要转换成另外一种上下行配 置， 以提高 TDD系统的频谱效率。 比如， 如果对于釆用配置为 1的 TDD系统 区域， 当该区域出现下行下载数据业务增多的情况时， 就需要将该区域转换成 下行子帧相对更多的配置为 2的 TDD 系统。 这样， 就会出现原来发上行数据 的子帧不再发上行数据了， 而改为发下行数据。 但是在该过程中会出现上行子 帧和下行子帧中同时有多个子帧进行转换， 造成控制信息发送位置在动态变化 时比较复杂和混乱， 从而导致系统处理的复杂度比较高且造成系统中断。 发明内容 本发明的主要目的在于提供一种数据传输方法、 装置及无线帧， 以解决上 述相关技术中数据传输方法导致的系统处理复杂度比较高且造成系统中断的 问题。 为了实现上述目的， 根据本发明的一个方面， 提供了一种数据传输方法， 应用于 TDD系统。 根据本发明的数据传输方法包括： 设置预定的上下行配置方式， 其中， 预 定的上下行配置方式将一个无线帧中的 10 个子帧配置为： 第一子帧、 第五子 帧、 第六子帧、 第九子帧和第十子帧为下行子帧， 第三子帧、 第四子帧和第八 子帧为上行子帧， 第二子帧和第六子帧为特殊子帧； 使用预定的上下行配置方 式进行数据传输。 主载波使用 LTE R8 TDD系统具有的上下行配置方式之一配置其上的无线 帧； 辅载波使用以下之一的配置方式配置其上的无线帧： 预定的上下行配置方 式、 LTE R8 TDD系统具有的上下行配置方式之一。 In the data transmission method in the related art, when a TDD system area of a certain configuration is used, when there is a different service type requirement in the area, the area needs to be converted into another uplink and downlink configuration to improve the spectrum of the TDD system. effectiveness. For example, if the TDD system area configured with 1 is used, when the downlink download data service increases in the area, the area needs to be converted into a TDD system with a relatively long downlink subframe configuration of 2. In this way, the subframe in which the uplink data was originally sent will no longer send uplink data, but will instead send downlink data. However, in this process, multiple subframes in the uplink subframe and the downlink subframe may be converted at the same time, which causes the control information sending position to be complex and confusing when dynamically changing, thereby causing high processing complexity and system interruption. .

由表 2可知： 一个无线帧包含了 10个子帧， 子帧号分别标记为： 0, 1 , 2, 3 , 4, 5 , 6, 7, 8, 9。 "D"表示该子帧为下行子帧； "U" 表示该子帧为上行子 帧； "S"表示该子帧为特殊子帧， 即该子帧既包含有上行传输的部分也包含有 下行传输的部分。 在本实施例中将新的 TDD上下行配置方式称为： 上下行配置 7。 TDD系 统使用 3个比特数据表示 8种上下行配置； 用表格表示如下： 表 3上下行子帧配置示意表 It can be seen from Table 2 that a radio frame contains 10 subframes, and the subframe numbers are respectively marked as: 0, 1 , 2, 3, 4, 5, 6, 7, 8, 9.

由表 3可知， 原来时分长期演进 ( TD-LTE ) 系统的 7种上下行配置需要 3 个比特数据来表示， TDD系统对这 3比特数据按照某种规则进行编码后， 表示 8种上下行配置。 现在增加一种新的上下行配置方式后， 仍然可以用 3个比特 数据来表示。 因此没有额外增加系统开销， 并且可以充分利用这 3比特数据资 源。 本实施例中的数据传输方法包括以下方式： 方式一：当釆用 TDD上下行配置 1的小区要转换成 TDD上下行配置 2时， 该小区需要先转换成 TDD上下行配置 7 , 然后再转换成 TDD上下行配置 2; 同理， 当釆用 TDD上下行配置 2的小区要转换成 TDD上下行配置 1时， 该小 区需要先转换成 TDD上下行配置 7 , 然后再转换成 TDD上下行配置 1。 需要说明的是， 在一个无线帧里， TDD上下行配置 7比配置 1只多一个下 行子帧， 而配置 2比配置 7也只多一个下行子帧。 配置 1先转换成配置 7然后 再转换成配置 2 , 或者配置 2先转换成配置 7然后再转换成配置 1 , 使得小区 的 TDD上下行配置变化具有连续性， 有利于保证在进行中的业务不中断和降 低系统处理的复杂度。 方式二 当釆用 TDD上下行配置 1的载波要转换成 TDD上下行配置 2时， 该载波 需要先转换成 TDD上下行配置 7 , 然后再转换成 TDD上下行配置 2; 同理， 当釆用 TDD上下行配置 2的载波要转换成 TDD上下行配置 1时， 该载波需要 先转换成 TDD上下行配置 7, 然后再转换成 TDD上下行配置 1。 需要说明的是， 对于釆用配置为 1 的 TDD 系统区域， 当该区域出现下行 下载数据业务增多的情况时， 就需要将该区域转换成下行子帧相对更多的配置 为 2的 TDD系统。 这样， 就会出现原来发上行数据的子帧不再发上行数据了， 而改为发下行数据。 配置 1与配置 2之间在一个无线帧里有 2个子帧不同， 如 果系统要在配置 1与配置 2之间进行动态变换的话， 容易导致控制信息发送位 置在动态变化时比较复杂和混乱， 并容易导致业务的中断。 因此， 如果要使 TD-LTE系统在配置 1与配置 2之间实现高效率的动态变换， 使用配置 7进行 中间转换， 可以保证在不中断业务的情况下顺利转换上下行配置， 且降低系统 转换的复杂度。 如果釆用配置 1与釆用配置 2的 TD-LTE系统相邻时， 中间就需要有一块 区域是釆用空子帧的配置， 以隔离上下行千扰。 但由于在一个无线帧里有 2个 子帧要设置成空子帧， 因此中间这块区域的资源浪费就比较大， 反而可能会降 低了整个 TD-LTE系统网络的效率。 方式三 当釆用 TDD上下行配置 3的小区要转换成 TDD上下行配置 1时， 该小区 需要先转换成 TDD上下行配置 7, 然后再转换成 TDD上下行配置 1 , 同理， 当釆用 TDD上下行配置 3的载波要转换成 TDD上下行配置 1时， 该载波需要 先转换成 TDD上下行配置 7, 然后再转换成 TDD上下行配置 1。 需要说明的是， 在本方式中， 在一个无线帧里， TDD上下行配置 7比配置 1只多一个下行子帧， 而配置 3比配置 7也只多一个下行子帧。 配置 3先转换 成配置 7然后再转换成配置 1 , 使得小区的 TDD上下行配置变化具有连续性， 有利于保证在进行中的业务不中断和降低系统处理的复杂度。 方式四 当釆用 TDD上下行配置 3的载波要转换成 TDD上下行配置 1时， 该载波 需要先转换成 TDD上下行配置 7, 然后再转换成 TDD上下行配置 1 , 同理， 当釆用 TDD上下行配置 1的载波要转换成 TDD上下行配置 3时， 该载波需要 先转换成 TDD上下行配置 7, 然后再转换成 TDD上下行配置 3。 方式五 当小区从上行较多的配置转换到下行较多的配置时， 需要按照如下的转换 顺序进行： 配置 0-— >配置 6-— >配置 1-— >配置 7-— >配置 2-— >配置 5。 方式六 当某载波从上行较多的配置转换到下行较多的配置时， 需要按照如下的转 换顺序进行： 配置 0-— >配置 6-— >配置 1-— >配置 7-— >配置 2-— >配置 5。 方式八 当小区从下行较多的配置转换到上行较多的配置时， 需要按照如下的转换 顺序进行： 配置 5-— >配置 4-— >配置 3-— >配置 7-— >配置 1-— >配置 6 -— >配置 0。 方式九 当某载波从下行较多的配置转换到上行较多的配置时， 需要按照如下的转 换顺序进行： 配置 5-— >配置 4-— >配置 3-— >配置 7-— >配置 1-— >配置 6 -— >配置 0。 方式十 当小区从下行较多的配置转换到上行较多的配置时， 还可以按照另外一种 转换顺序进行如下： 配置 5-— >配置 2-— >配置 7-— >配置 1-— >配置 6 -— >配置 0。 可以看出， 增加了 TDD上下行配置 7之后， TD-LTE系统的上下行配置变 化更加具有连续性， 有利于保证在进行中的业务不中断和降低系统处理的复杂 度。 方式十一 当某载波从下行较多的配置转换到上行较多的配置时， 还可以按照另外一 种转换顺序进行如下： 配置 5-— >配置 2-— >配置 7-— >配置 1-— >配置 6 -— >配置 0。 优选地， 在多载波 TDD系统中， 主载波釆用上下行配置 0、 配置 1、 配置 2、 配置 3、 配置 4、 配置 5、 配置 6这 7种配置中的任何一种； 某一个副载波 可以釆用上下行配置 0至配置 7这 8种配置中的任何一种。 这样， 主载波釆用 原来的配置可以 艮好地保持终端的后向兼容性问题； 副载波釆用新的配置 7可 以 艮好地增强终端在 TDD配置动态变化的灵活性。 需要说明的是， 5ms周期的 TDD帧结构比 10ms周期的 TDD帧结构在时 延敏感性业务方面更有优势， 因此增加一个 5ms周期内使用本实施例的方法， 增加配置 7 , 使系统配置更合理。 而且配置 7的上下行比例比较适合现在的数 据业务类型， 使用频度很高， 提高系统传输效率。 且配置 1和 2这两种方式的 上行传输资源与下行传输资源的比例比较适中， 能够适应业务类型在不断变化 的区域使用，因此 TD-LTE系统实际应用中釆用配置 1与配置 2的时候会更多。 这样， 如果在配置 1与配置 2之间增加一种配置 7 , 这种新配置的应用场景也 会比较多， 可以优化系统的数据传输。 本实施例提供了一种数据传输装置， 图 2是根据本发明实施例的数据传输 装置的结构框图， 如图 2所示， 该装置包括： 设置模块 22和传输模块 24 , 下 面对上述结构进行详细描述： 设置模块 22 , 设置为设置无线帧的子帧格式中的预定的上下行配置方式， 其中， 预定的上下行配置方式将一个无线帧中的 10个子帧配置为： 第一子帧、 第五子帧、 第六子帧、 第九子帧和第十子帧为下行子帧， 第三子帧、 第四子帧 和第八子帧为上行子帧， 第二子帧和第六子帧为特殊子帧； 传输模块 24 , 连接 至设置模块 22 , 设置为使用设置模块设置 22设置的所述预定的上下行配置方 式进行数据传输。 图 3是根据本发明实施例的数据传输装置的优选的结构框图，如图 3所示， 该装置还包括： 第一子帧配置模块 32 , 第二子帧配置模块 34 , 第一转换子模 块 241 , 第一格式转换子模块 242 , 第二转换子模块 243 , 第二格式转换子模块 244 , 第三转换子模块 245 , 第三格式转换子模块 246 , 第四转换子模块 247 , 第四格式转换子模块 248 , 第五转换子模块 249 , 第六转换子模块 250 , 第七转 换子模块 251 , 下面对上述结构进行详细描述： 上述装置还包括： 第一子帧配置模块 32 , 设置为配置主载波使用 LTE R8 TDD系统具有的上下行配置方式之一配置其上的子帧； 第二子帧配置模块 34 , 设置为辅载波使用以下之一的配置方式配置其上的子帧： 预定的上下行配置方 式、 LTE R8 TDD系统具有的上下行配置方式之一。 第一转换子模块 241 , 设置为在无线帧配置从上下行配置方式 1转换为上 下行配置方式 2时， 将无线帧配置从上下行配置方式 1转换为预定的上下行配 置方式； 第一格式转换子模块 242 , 连接至第一转换子模块 241 , 设置为将第 一转换子模块 241转换得到的无线帧配置从预定的上下行配置方式转换为上下 行配置方式 2 , 其中， 每次上下行配置方式转换过程中， 一个无线帧中只有一 个子帧发生变化， 无线帧配置为以下之一： 小区的无线帧配置、 载波的无线帧 配置。 第二转换子模块 243 , 设置为在无线帧配置从上下行配置方式 2转换为上 下行配置方式 1时， 将无线帧配置从上下行配置方式 2转换为预定的上下行配 置方式； 第二格式转换子模块 244, 连接至第二转换子模块 243 , 设置为将第 二转换子模块 243转换得到的无线帧配置从预定的上下行配置方式转换为上下 行配置方式 1 , 其中， 每次上下行配置方式转换过程中， 一个无线帧中只有一 个子帧发生变化无线帧配置为以下之一： 小区的无线帧配置、 载波的无线帧配 置。 第三转换子模块 245, 设置为在无线帧配置从上下行配置方式 1转换为上 下行配置方式 3时， 将无线帧配置从上下行子帧配置方式 1转换为预定的上下 行配置方式； 第三格式转换子模块 246 , 连接至第三转换子模块 245, 设置为 将第三转换子模块 245转换得到的无线帧配置从预定的上下行配置方式转换为 上下行配置方式 3 , 其中， 无线帧配置为以下之一： 小区的子帧无线帧配置、 载波的无线帧配置。 第四转换子模块 247, 设置为在无线帧配置从上下行配置方式 3转换为上 下行配置方式 1时， 将无线帧配置从上下行配置方式 3转换为预定的上下行配 置方式； 第四格式转换子模块 248, 连接至第四转换子模块 247, 设置为将第 四转换子模块 247转换得到的无线帧配置从预定的上下行配置方式转换为上下 行配置方式 1 , 其中， 无线帧配置为以下之一： 小区的无线帧配置、 载波的无 线帧配置。 第五转换子模块 249 , 设置为使用如下顺序进行无线帧配置的转换： 上下 行配置方式 0--->上下行配置方式 6--->上下行配置方式 1--->预定的上下行配置 方式一 >上下行子帧配置方式 2--->上下行子帧配置方式 5 , 其中， 无线帧配置 为以下之一： 小区的无线帧配置、 载波的无线帧配置。 第六转换子模块 250 , 设置为使用如下顺序进行无线帧配置的转换： 上下 行配置方式 5--->上下行配置方式 4--->上下行配置方式 3--->预定的上下行配置 方式一 >上下行配置方式 1--->上下行配置方式 6 -

After the TDD system encodes the three bits of data according to certain rules, it indicates eight uplink and downlink configurations. . Now, after adding a new uplink and downlink configuration mode, it can still be represented by 3 bits of data. Therefore, there is no additional system overhead, and the 3-bit data resource can be fully utilized. The data transmission method in this embodiment includes the following manners: Mode 1: When a cell that uses TDD uplink and downlink configuration 1 is to be converted into a TDD uplink and downlink configuration 2, the cell needs to be converted into a TDD uplink and downlink configuration 7 first, and then converted. In the TDD uplink and downlink configuration 2; similarly, when the cell using the TDD uplink and downlink configuration 2 is to be converted into the TDD uplink and downlink configuration 1, the cell needs to be converted into the TDD uplink and downlink configuration 7, and then converted into the TDD uplink and downlink configuration. 1. It should be noted that, in a radio frame, the uplink and downlink configuration 7 of the TDD is only one more downlink subframe than the configuration 1, and the configuration 2 has only one downlink subframe more than the configuration 7. Configuration 1 is first converted to configuration 7 and then converted to configuration 2, or configuration 2 is first converted to configuration 7 and then to configuration 1 to make the TDD uplink and downlink configuration changes of the cell have continuity, which is beneficial to ensure that the ongoing service is not Interrupt and reduce the complexity of system processing. In the second mode, when the carrier of the TDD uplink and downlink configuration 1 is to be converted into the TDD uplink and downlink configuration 2, the carrier needs to be converted into the TDD uplink and downlink configuration 7 first, and then converted into the TDD uplink and downlink configuration 2; similarly, When the carrier of the TDD uplink and downlink configuration 2 is to be converted into the TDD uplink and downlink configuration 1, the carrier needs to be converted into the TDD uplink and downlink configuration 7 and then converted into the TDD uplink and downlink configuration 1. It should be noted that, when the TDD system area configured with 1 is used, when the downlink download data service increases in the area, the area needs to be converted into a TDD system with a relatively long downlink subframe configuration of 2. In this way, the subframe in which the uplink data was originally sent will no longer send uplink data, but will instead send downlink data. There are two sub-frames in a radio frame between configuration 1 and configuration 2. If the system is to dynamically change between configuration 1 and configuration 2, it is easy to cause the control information sending position to be more complicated and chaotic when dynamically changing, and It is easy to cause business interruption. Therefore, if you want to enable the TD-LTE system to achieve high-efficiency dynamic conversion between configuration 1 and configuration 2, use configuration 7 for intermediate conversion, which can ensure smooth transition of uplink and downlink configuration without interrupting services, and reduce system conversion. The complexity. If the configuration 1 is adjacent to the TD-LTE system configured with the configuration 2, an intermediate area is required to be configured with an empty subframe to isolate the uplink and downlink interference. However, since there are 2 subframes in a radio frame to be set as null subframes, the resource waste in the middle region is relatively large, which may reduce the efficiency of the entire TD-LTE system network. Mode 3: When the cell with TDD uplink and downlink configuration 3 is to be converted to TDD uplink and downlink configuration 1, the cell needs to be converted into TDD uplink and downlink configuration 7 first, and then converted to TDD uplink and downlink configuration 1. Similarly, when used When the carrier of the TDD uplink and downlink configuration 3 is to be converted into the TDD uplink and downlink configuration 1, the carrier needs to be converted into the TDD uplink and downlink configuration 7 and then converted into the TDD uplink and downlink configuration 1. It should be noted that, in this mode, in one radio frame, the TDD uplink and downlink configuration 7 is only one more downlink subframe than the configuration 1, and the configuration 3 is only one more downlink subframe than the configuration 7. The configuration 3 is first converted into the configuration 7 and then converted into the configuration 1 to make the TDD uplink and downlink configuration changes of the cell have continuity, which is beneficial to ensure that the ongoing services are not interrupted and the complexity of the system processing is reduced. Mode 4: When the carrier of TDD uplink and downlink configuration 3 is to be converted into TDD uplink and downlink configuration 1, the carrier needs to be converted into TDD uplink and downlink configuration 7 first, and then converted into TDD uplink and downlink configuration 1. Similarly, when used When the carrier of the TDD uplink and downlink configuration 1 is to be converted into the TDD uplink and downlink configuration 3, the carrier needs to be converted into the TDD uplink and downlink configuration 7 and then converted into the TDD uplink and downlink configuration 3. Mode 5 When the cell transitions from the uplink configuration to the downlink configuration, the following conversion sequence is required: Configuration 0-—>Configuration 6-—>Configuration 1-—>Configuration 7-—Configuration 2- — > Configuration 5. Mode 6 When a carrier transitions from a higher uplink configuration to a lower downlink configuration, the following conversion sequence is required: Configuration 0-—>Configuration 6-—>Configuration 1-—>Configuration 7-—>Configuration 2 ->> Configuration 5. Mode 8 When the cell transitions from the downlink configuration to the uplink configuration, the following conversion sequence is required: Configuration 5-->Configuration 4-->Configuration 3-->Configuration 7-->Configuration 1- —>Configuration 6 — — > Configuration 0. Mode 9 When a carrier is switched from a downlink configuration to a larger uplink configuration, the following conversion sequence is required: Configuration 5-->Configuration 4-->Configuration 3-->Configuration 7-->Configuration 1 ->> Configuration 6 - - > Configuration 0. Mode 10 When a cell transitions from a downlink configuration to a larger uplink configuration, it can also be performed in another conversion sequence as follows: Configuration 5-->Configuration 2-->Configuration 7-->Configuration 1--> Configuration 6 - - > Configuration 0. It can be seen that after the TDD uplink and downlink configuration 7 is added, the uplink and downlink configuration changes of the TD-LTE system are more continuous, which is beneficial to ensure that the ongoing services are not interrupted and the complexity of the system processing is reduced.
