Description

一种数据信息发送方法及其装置  Data information transmitting method and device thereof
技术领域 Technical field
本发明涉及一种无线通信技术， 尤其涉及一种数据信息发送方法及其装 置。 背景技术  The present invention relates to a wireless communication technology, and in particular, to a data information transmission method and apparatus thereof. Background technique
在现有的 TDD ( Time Division Duplex, 时分双工 )移动通信系统中， 下 行时隙和上行时隙之间只设置有 GP (可以理解为一种保护时隙）作为保护间 隔。 如图 1所示， 通常， 数据帧中的第一个时隙为下行时隙， 其后依次为同步 符号和 GP, GP之后为上行时隙 （可有多个上行时隙） ， 上行时隙之后可能还 有若干个下行时隙。  In the existing TDD (Time Division Duplex) mobile communication system, only a GP (which can be understood as a guard slot) is provided as a guard interval between the downlink time slot and the uplink time slot. As shown in FIG. 1 , generally, the first time slot in the data frame is a downlink time slot, followed by a synchronization symbol and a GP, and an GP is followed by an uplink time slot (which may have multiple uplink time slots), and an uplink time slot. There may then be several downstream time slots.
在 TDD系统中， 由于上下行信道共享同一载频， 所以其它基站的下行信 号会经过延迟到达用户所在基站， 如果时延超过保护时隙长度， 则一个基站 的下行信号会对另一个基站小区的上行接收信号产生干扰。 尤其在某些情况 下， 为了保证同步符号的正确接收， 需要提升同步符号的发射功率， 这就会 加剧基站之间的干扰。  In the TDD system, since the uplink and downlink channels share the same carrier frequency, the downlink signals of other base stations will arrive at the base station where the user is located after delay. If the delay exceeds the length of the protection time slot, the downlink signal of one base station will be the base station of another base station. The uplink received signal generates interference. Especially in some cases, in order to ensure the correct reception of the synchronization symbol, it is necessary to increase the transmission power of the synchronization symbol, which will exacerbate the interference between the base stations.
为了避免基站之间的干扰， 可以提供更大的保护间隔， 但是这样又会带 来额外的无线资源开销， 降低系统的效率。 发明内容  In order to avoid interference between base stations, a larger guard interval can be provided, but this will bring additional radio resource overhead and reduce system efficiency. Summary of the invention
本发明的实施例揭示了一种数据信息发送方法及其装置， 以实现在不增 加系统开销和资源消耗的情况下， 降低基站之间的信号干扰。  Embodiments of the present invention disclose a data information transmitting method and apparatus thereof to reduce signal interference between base stations without increasing system overhead and resource consumption.

所述信号发送端在所述下行时隙的开始部分， 或在与所述上行时隙不相 邻的下行时隙的结尾部分， 或在两个相邻下行时隙间， 发送同步信息。 The signal transmitting end is at the beginning of the downlink time slot, or is not in phase with the uplink time slot The end portion of the downstream downlink slot, or between two adjacent downlink slots, transmits synchronization information.
本发明实施例揭示的数据信息发送装置， 包括：  The data information sending apparatus disclosed in the embodiment of the present invention includes:
设置模块， 用于设置数据帧， 所述数据帧依次包括至少一个下行时隙、 保护时隙， 以及至少一个上行时隙； 并在所述下行时隙的开始部分， 或在与 所述上行时隙不相邻的下行时隙的结尾部分， 或在两个相邻下行时隙间 , 设 置承载同步信息；  a setting module, configured to set a data frame, where the data frame includes at least one downlink time slot, a protection time slot, and at least one uplink time slot in sequence; and at a beginning portion of the downlink time slot, or during the uplink Bearer synchronization information is set at the end of the downlink slot that is not adjacent to the slot, or between two adjacent downlink slots;
发送模块， 用于发送设置的所述数据帧。  a sending module, configured to send the set data frame.
本发明的上述实施例， 通过在发送数据帧时， 依次发送下行时隙、 保护 时隙以及上行时隙， 并将同步信息承载于下行时隙的开始部分， 或承载于与 上行时隙不相邻的下行时隙的结尾部分， 或者承载于两个相邻下行时隙间， 使发送的同步信息尽可能远离上行时隙， 从而在不增加保护时隙开销和其它 资源消耗的情况下， 可以降低在需要对同步符号进行功率提升时其它基站对 发送所述数据帧的基站上行接收信号的干扰， 降低对保护时隙长度的要求， 从而降低系统的开销。 附图说明  In the above embodiment of the present invention, when transmitting a data frame, the downlink time slot, the protection time slot, and the uplink time slot are sequentially transmitted, and the synchronization information is carried in the beginning part of the downlink time slot, or is carried in the uplink time slot. The end portion of the downlink downlink time slot, or carried between two adjacent downlink time slots, so that the transmitted synchronization information is as far as possible from the uplink time slot, so that without increasing the protection time slot overhead and other resource consumption, The interference of other base stations on the uplink receiving signals of the base station transmitting the data frame when the power of the synchronization symbol needs to be boosted is reduced, and the requirement for the protection time slot length is reduced, thereby reducing the overhead of the system.

为了便于本领域一般技术人员理解和实现本发明， 现结合附图描绘本发 明的实施例。 在本发明的一个实施例中， 通过改变上行时隙和下行时隙的排列位置， 以及同步符号 （同步符号可能由 1个或多个 OFDM符号组成） 的承载位置， 使 干扰。 In order to facilitate a person skilled in the art to understand and implement the invention, embodiments of the invention are now described in conjunction with the drawings. In one embodiment of the present invention, interference is caused by changing the arrangement positions of the uplink and downlink time slots, and the bearer positions of the synchronization symbols (the synchronization symbols may be composed of one or more OFDM symbols).
本实施例中的数据帧的时隙结构如图 2所示， 图中每个实线格表示一个时 隙。 图 2所示的数据帧中依次包括多个下行时隙、 一个保护时隙以及多个上行 时隙， 在第一个下行时隙后有一个用于承载同步信号的时隙。 保护时隙的长 度可以与现有系统中的保护时隙的长度相同。 用于承载同步符号的时隙中可 承载有主同步信道信息以及辅同步信道信息。 从图 2可以看出， 同步符号与上 行时隙之间间隔有多个下行时隙， 因此即便在需要功率提升的情况下， 对上 行时隙的干扰也不会太大。  The slot structure of the data frame in this embodiment is as shown in Fig. 2, and each solid line in the figure represents a time slot. The data frame shown in FIG. 2 includes a plurality of downlink time slots, one protection time slot, and a plurality of uplink time slots in sequence, and a time slot for carrying the synchronization signal after the first downlink time slot. The length of the guard slot can be the same as the length of the guard slot in the existing system. The time slot for carrying the synchronization symbol may carry primary synchronization channel information and secondary synchronization channel information. It can be seen from Fig. 2 that there are multiple downlink time slots between the synchronization symbol and the uplink time slot, so even if the power boost is required, the interference to the uplink time slot is not too large.
为了进一步提高系统的资源利用率， 可以在承载同步符号的时隙中， 利 用同步信号占用的资源以外的资源承载其它的数据， 如用户数据或控制信息 等。 在本发明的另一个实施例中， 通过改变上行时隙和下行时隙的排列位置， 以及同步符号 （同步符号可能由 1个或多个 OFDM符号组成） 的承载位置， 使 干扰。  In order to further improve the resource utilization of the system, resources other than the resources occupied by the synchronization signal may be used to carry other data, such as user data or control information, in the time slot carrying the synchronization symbol. In another embodiment of the present invention, interference is caused by changing the arrangement positions of the uplink and downlink time slots, and the bearer positions of the synchronization symbols (the synchronization symbols may be composed of one or more OFDM symbols).
本实施例中的数据帧的时隙结构如图 3所示， 图中的每个实线格表示一个 时隙。 图 3所示的数据帧中依次包括多个下行时隙、 一个保护时隙以及多个上 行时隙。 保护时隙的长度可以与现有系统中的保护时隙的长度相同。 其中， 在第一个下行时隙中的虚线表示同步符号的位置。 由图 3可见， 同步符号占用 第一个下行时隙的后尾位置， 之后依次为若干个下行时隙、 保护时隙和若干 个上行时隙。 第一个下行时隙中承载同步信号的位置可以是该时隙的最后一 个或多个数据符号， 或接近该时隙最后位置的一个或多个数据符号。 例如， 如果第一个下行时隙可承载 N个数据符号， 则第 N个数据符号， 或第 N个和第 N-l个数据符号， 或第 N-l个和第 N-2个数据符号， 用来承载同步符号。 用于承 载同步符号的时隙中可承载有主同步信道信息以及辅同步信道信息。 从图 3可 以看出， 同步符号与上行时隙之间间隔有多个下行时隙， 因此， 即便在需要 功率提升的情况下， 同步符号对上行时隙的干扰也不会太大。 The slot structure of the data frame in this embodiment is as shown in FIG. 3, and each solid line in the figure represents one slot. The data frame shown in FIG. 3 sequentially includes a plurality of downlink time slots, one protection time slot, and a plurality of uplink time slots. The length of the guard slot can be the same as the length of the guard slot in the existing system. Among them, the broken line in the first downlink time slot indicates the position of the synchronization symbol. As can be seen from FIG. 3, the synchronization symbol occupies the rear tail position of the first downlink time slot, and then is followed by several downlink time slots, guard time slots and several uplink time slots. The location in the first downlink time slot carrying the synchronization signal may be the last one or more data symbols of the time slot, or one or more data symbols near the last position of the time slot. For example, if the first downlink time slot can carry N data symbols, then the Nth data symbol, or the Nth and the N1 data symbols, or N1th and N-2th data symbols, are used to carry synchronization symbols. The time slot for carrying the synchronization symbol may carry primary synchronization channel information and secondary synchronization channel information. As can be seen from FIG. 3, there are multiple downlink time slots between the synchronization symbol and the uplink time slot. Therefore, even if power boosting is required, the synchronization symbol does not interfere too much with the uplink time slot.
为了进一步提高系统的资源利用率， 可以在承载同步符号的数据符号中， 利用同步信号占用的资源以外的资源承载其它的数据， 如用户数据或控制信 息等。 在本发明另一个实施例中， 通过改变上行时隙和下行时隙的排列位置， 以及同步符号 （同步符号可能由 1个或多个 OFDM符号组成） 的承载位置， 使 干扰。  In order to further improve the resource utilization of the system, resources other than the resources occupied by the synchronization signal may be used to carry other data, such as user data or control information, in the data symbols carrying the synchronization symbols. In another embodiment of the present invention, interference is caused by changing the arrangement positions of the uplink and downlink time slots, and the bearer positions of the synchronization symbols (the synchronization symbols may be composed of one or more OFDM symbols).
本实施例中的数据帧的时隙结构示意图如图 4所示， 图中的每个实线格表 示一个时隙。 图 4所示的数据帧中依次包括多个下行时隙、 一个保护时隙以及 多个上行时隙。 保护时隙的长度可以与现有系统中的保护时隙的长度相同。 图中第二个下行时隙中的虚线表示同步符号的位置。 由图 4可见， 同步符号占 用第二个下行时隙的首位置， 之后依次为下行时隙， 保护间隔和上行时隙。 第二个下行时隙中承载同步信号的位置可以是该时隙的最开始的一个或多个 数据符号， 或接近该时隙最开始位置的一个或多个数据符号。 例如， 如果第 二个下行时隙可承载 N个数据符号， 则第 1个数据符号， 或第 1个和第 2个数据 符号， 或第 2个和第 3个数据符号， 用来承载同步符号。 用于承载同步符号的 时隙中可承载有主同步信道信息以及辅同步信道信息。  A schematic diagram of the slot structure of the data frame in this embodiment is shown in FIG. 4, and each solid line in the figure represents a slot. The data frame shown in FIG. 4 sequentially includes a plurality of downlink time slots, one guard time slot, and a plurality of uplink time slots. The length of the guard slot can be the same as the length of the guard slot in the existing system. The dashed line in the second downlink time slot in the figure indicates the position of the synchronization symbol. As can be seen from Figure 4, the synchronization symbol occupies the first position of the second downlink time slot, followed by the downlink time slot, the guard interval and the uplink time slot. The location in the second downlink time slot carrying the synchronization signal may be the first one or more data symbols of the time slot, or one or more data symbols near the beginning of the time slot.
