组网方式的指示方法、 频率分区的确定方法及系统 技术领域 本发明涉及通信领域, 具体而言, 涉及一种组网方式的指示方法、 频率 分区的确定方法及系统。 背景技术 无线通信系统中, 基站是给终端提供服务的设备。 基站通过上、 下行链 路与终端进行通信, 下行是指基站到终端的方向, 上行是指终端到基站的方 向。 多个终端可同时通过上行链路向基站发送数据, 也可以通过下行链路同 时从基站接收数据。 无线通信系统中无线资源的资源映射的主要依据是该无线通信系统的帧 结构和资源结构。 其中, 帧结构描述了无线通信系统中无线资源的整体控制 结构, 主要表现的是时域上的划分, 资源结构描述了无线通信系统中无线资 源的分配结构, 主要表现的是频域上的划分。 在未来的无线通信系统中(例如,以正交频分复用( Orthogonal Frequency Division Multiplexing ,简称为 OFDM )和正交频分多址( Orthogonal Frequency Division Multiple Access , 简称为 OFDMA )技术为基础的无线通信系统中), 帧结构一般具有如下特征: 将无线资源划分成超帧、 帧、 子帧和符号进行调 度。 首先将无线资源划分为时间连续的超帧, 每个超帧包含多个帧, 每个帧 又包含多个子帧, 子帧由最基本的 OFDM 符号组成, 超帧中帧、 子帧以及 OFDM符号的数目由 OFDM 系统的基本参数决定。 为了提高传输效率, 可 以将多个子帧进行级联进行统一调度。 例如图 1所示的电气和电子工程师协 会 ( Institute for Electrical and Electronic Engineers, 简称为 IEEE ) 802.16m系 统的一种帧格式, 无线资源在时域上划分为超帧, 每个超帧包含 4个帧, 每 个帧包含 8个子帧, 子帧由 6 (或 5 或 7 ) 个基本的 OFDM符号组成。 无线通信系统的资源结构的主要特征是: 将无线资源分成多个频率分区 TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a method for indicating a networking mode, a method for determining a frequency partition, and a system. Background Art In a wireless communication system, a base station is a device that provides a service to a terminal. The base station communicates with the terminal through the uplink and downlink links, the downlink refers to the direction from the base station to the terminal, and the uplink refers to the direction from the terminal to the base station. Multiple terminals can transmit data to the base station through the uplink at the same time, or can receive data from the base station through the downlink at the same time. The main basis for resource mapping of radio resources in a wireless communication system is the frame structure and resource structure of the radio communication system. The frame structure describes the overall control structure of the radio resources in the wireless communication system, and mainly represents the division in the time domain. The resource structure describes the allocation structure of the radio resources in the wireless communication system, and the main performance is the division in the frequency domain. . In future wireless communication systems (for example, wireless based on Orthogonal Frequency Division Multiplexing (OFDM) and Orthogonal Frequency Division Multiple Access (OFDMA) technology) In a communication system, a frame structure generally has the following features: The radio resources are divided into super frames, frames, subframes, and symbols for scheduling. First, the radio resources are divided into time-continuous superframes, each superframe consists of multiple frames, and each frame contains multiple sub-frames, which are composed of the most basic OFDM symbols, super-frame frames, sub-frames, and OFDM symbols. The number is determined by the basic parameters of the OFDM system. In order to improve transmission efficiency, multiple subframes may be cascaded for unified scheduling. For example, in the frame format of the Institute for Electrical and Electronic Engineers (IEEE) 802.16m system shown in Figure 1, the radio resources are divided into superframes in the time domain, and each superframe contains four frames. Frame, each frame contains 8 subframes, and the subframe consists of 6 (or 5 or 7) basic OFDM symbols. The main features of the resource structure of a wireless communication system are: Dividing wireless resources into multiple frequency partitions
( Frequency Partition, 简称为 FP ), 每个频率分区内可以独立的调度各个用 户, 一个 IEEE802.16m系统中的具体示例如图 2所示, 一个子帧的可用物理 子载波被分成 4个频率分区 ( FPO, FP1 , FP2, FP3 ), 每个频率分区分为集 中式资源和分布式资源用于实现调度的灵活性。 在釆用基站实现无线资源调度控制的无线通信系统中, 系统的许多参数 分配由基站通过发送广播、 组播或者单播消息 (广播消息是指基站发送给所 有用户的消息, 所有接入的用户都能接收; 组播消息是指基站发送给一部分 用户的消息, 只有在该消息所关联的特定组内的用户才接收; 单播消息是指 基站发送给某个特定用户的消息, 仅该指定用户接收) 将参数发送给终端, 比如, 在使用 IEEE802.16m协议的通信系统中, 许多系统内的网元都必须知 道的公共参数的分配由基站通过发送多种类型的广播消息, 例如: 主-超帧头 /二级 -超†贞头 ( Primary-Super Frame Header I Secondary - Super Frame Header, 简称为 P-SFH/S-SFH ) , 在 S-SFH 中通过相应的信息元素 (Information Element, 简称为 IE ) 将相关信息发送给各个终端, 如果终端能正确的接收 到相关的二级超帧头中的信息之后, 就可以读取相关参数和基站发来的公共 指令, 并按照相应的参数和指令釆取正确的行动。 而某些对特定的用户, 基 站可以发送各种单播管理消息将相应的参数传递给相应的终端。 以正交频分复用和正交频分多址技术为基础的无线通信系统中, 本小区 内的基站受到的其他小区内终端的同频千扰, 即为上行小区间千扰; 本小区 内的终端受到的其他小区内基站的同频千扰, 即下行小区间千扰。 上行小区 间千扰和下行小区间千扰统称为小区间千扰。 降低小区间千扰对系统性能的 影响是 OFDM系统设计的一个重要目标, 如果小区间的千扰严重, 则会降低 系统容量, 特别是降低小区边缘用户的传输能力, 进而影响系统的覆盖能力 以及终端的性能。 为了有效克服上行小区间千扰, 需要合理的规划各个扇区使用的上行频 率资源,尽量使相邻扇区使用的频率资源互相正交, 降低或避免小区间千扰, 可以釆用分段 ( segment ) 方式组网, Segment组网, 即分段组网, N个基站 都可以在相同的频率资源发送和接收信号, 但各个基站之间所使用的子载波 互相正交, 不存在同频千 4尤。 如图 3所示为一种 segment方式组网的频率分 区划分示意图, ^!夺可用频率资源划分为三份(FP1、 FP2、 FP3 ), 三个相邻的 扇区 (扇区 1、 扇区 2、 扇区 3 )分别使用一份频率分区上的资源, 这样就可 以避免三个扇区内的用户因为使用相同的频率资源而导致的小区间千 4尤。 如 图 4所示为另一种 segment方式组网的频率分区划分示意图, 将可用频率资 源划分为四份 (FP0、 FP1、 FP2、 FP3 ), 三个 的扇区 (扇区 1、 扇区 2、 扇区 3 ) 分别使用一份频率分区上的资源, 并且公用相同的频率资源 FP0, 这样不仅可以避免三个扇区内的用户因为使用相同的频率资源而导致的小区 间千扰, 而且还可以由于公用 FP0资源提高系统的容量。 针对现有技术中, 基站釆用 segment组网方式, 使用多个频率分区进行 通信, 导致终端无法确定在多个频率分区中自己可用的是哪个频率分区, 继 而导致通信失败。 发明内容 本发明的主要目的在于提供一种组网方式的指示方法、 频率分区的确定 方法及系统, 以解决上述问题至少之一。 为了实现上述目的, 才艮据本发明的一个方面, 提供了一种组网方式的指 示方法。 才艮据本发明的组网方式的指示方法包括: 基站向终端发送消息, 其中消 息用于指示基站釆用 segment组网方式。 进一步地, 基站向终端发送消息包括: 基站通过下行信道向终端发送上 行 segment组网方式指示信息和 /或下行 segment组网方式指示信息。 进一步地, 釆用主-超帧头、 二级 -超帧头或系统配置描述消息携带信息。 进一步地, 信息釆用 bitmap方式描述。 进一步地, 上述方法还包括: 终端接收消息, 居消息的指示确定基站 釆用 segment组网方式;

A specific example in an IEEE802.16m system is shown in Figure 2. The available physical subcarriers of one subframe are divided into four frequency partitions. (FPO, FP1, FP2, FP3), each frequency partition is divided into sets Chinese and distributed resources are used to achieve scheduling flexibility. In a wireless communication system in which a base station implements radio resource scheduling control, many parameter assignments of the system are transmitted by the base station by broadcasting, multicast, or unicast messages (the broadcast message refers to a message sent by the base station to all users, and all accessed users) The multicast message refers to the message sent by the base station to a part of the user, and is only received by the user in the specific group to which the message is associated; the unicast message refers to the message sent by the base station to a specific user, only the designation The user receives) sending parameters to the terminal. For example, in a communication system using the IEEE802.16m protocol, the allocation of common parameters that must be known by the network elements in many systems is transmitted by the base station by sending various types of broadcast messages, for example: - Primary-Super Frame Header I Secondary - Super Frame Header (P-SFH/S-SFH), which passes the corresponding information element (Information Element, in S-SFH). Referred to as IE), the relevant information is sent to each terminal. If the terminal can correctly receive the information in the relevant secondary superframe header, Related parameters can be read and sent to the base station common instructions, and taking corrective action in accordance with Bian appropriate parameters and instructions. And for some specific users, the base station can send various unicast management messages to pass the corresponding parameters to the corresponding terminals. In a wireless communication system based on orthogonal frequency division multiplexing and orthogonal frequency division multiple access (OFDM) technology, the same frequency interference of terminals in other cells received by the base station in the cell, that is, interference between uplink cells; The intra-cells in other cells are interfered by the same frequency, that is, the inter-cell interference. The inter-cell interference and the inter-cell interference are collectively referred to as inter-cell interference. Reducing the impact of inter-cell interference on system performance is an important goal of OFDM system design. If the interference between cells is severe, the system capacity will be reduced, especially the transmission capacity of the cell edge users will be reduced, which will affect the coverage capability of the system. Terminal performance. In order to effectively overcome the inter-cell interference, it is necessary to reasonably plan the uplink frequency resources used by each sector, and try to make the frequency resources used by adjacent sectors orthogonal to each other, and reduce or avoid inter-cell interference. Segment) Mode networking, Segment networking, that is, segmented networking, N base stations can transmit and receive signals on the same frequency resource, but the subcarriers used between each base station are orthogonal to each other, and there is no same frequency. 4 especially. Figure 3 shows a schematic diagram of frequency partitioning in a segment mode network, ^! The available frequency resources are divided into three parts (FP1, FP2, FP3), and three adjacent sectors (sector 1, sector 2, sector 3) use a resource on a frequency partition, so that it can be avoided. Users in three sectors are inter-cells due to the use of the same frequency resources. FIG. 4 is a schematic diagram of frequency partition division of another segment mode networking, dividing available frequency resources into four (FP0, FP1, FP2, and FP3), three sectors (sector 1, sector 2) , sector 3) respectively use a resource on a frequency partition, and share the same frequency resource FP0, This not only avoids inter-cell interference caused by users in three sectors due to the use of the same frequency resources, but also increases the capacity of the system due to the common FP0 resources. In the prior art, the base station uses the segment networking mode to communicate using multiple frequency partitions, which causes the terminal to be unable to determine which frequency partition is available to itself in multiple frequency partitions, which in turn causes communication failure.
