Description

小区间信息的交互方法及系统 技术领域 本发明涉及通信领域, 具体而言, 涉及一种小区间信息的交互方法及系统。 背景技术 在长期演进 (Long Term Evolution, 简称为 LTE) 系统的版本 (Release, 简称 R)
8/9及高级长期演进系统 (Long-Term Evolution Advance, 简称为 LTE- Advance) 系统 版本的 R10中, 下行控制信令一般配置在前 N个正交频分复用(Orthogonal Frequency Division Multiplexing, 简称为 OFDM)符号上发送, 这 N个符号一般被称为控制信令 传输区域, 其中, N可配置为 1, 2, 3, 4。 这 N个符号的可用于传输的频域资源全部 用于控制信令的传输。 控制信令传输区域的可用传输资源被划分为多个控制信道单元 (Control Channel Element, 简称为 CCE) 资源单位, 控制信息占用资源以 CCE为单位进行分配, 一般 为 1、 2、 4、 8个 CCEs, 这里的资源单位 CCE又可以进一步的细分为多个资源粒子组 (Resource Element Group, 简称为 REGs), 一个 CCE由多个不连续的 REGs组成, 一 般是 9个 REGs构成一个 CCE, 再进一步地, 每个 REG由多个基本资源单位组成。 由此可以看出, 用户分配的控制信令传输资源不是连续的, 从而使得控制信令区 域只能使用分集技术而很难使用闭环预编码技术, 其主要原因是解调导频和反馈方面 有很大的设计难度, 因此, 已有的版本中控制信令都是只支持非连续资源传输和分集 技术。 在 R10之后的版本中,为了提高控制信道的传输容量,支持更多用户的控制信令, 考虑开辟了新的控制信道区域, 并且, 同一用户设备 (User Equipment, 简称为 UE) 的控制信令传输资源可以是连续的时频资源, 从而可以支持闭环预编码技术。 图 1是根据相关技术的新旧版本中的控制信令区域的示意图。 R10之后的新版本 可以使得控制信令传输时支持闭环预编码技术, 提升控制信令容量支持更多个用户的 控制信令。图 2是根据相关技术的频域位置与干扰之间的关系的示意图。 R10之前(包 括 R10) 的老版本资源较分散, 控制信令受到的干扰在有的传输资源上大, 在有的资 源上小, 因此, 从整体来看, 很少出现所有传输资源都受到很大程度干扰的情况。 而 在 R10之后的新版本中, 在引入的新的控制信息传输位置中, UE分配的资源是连续 的, 因此, 各部分受到的干扰情况很相似, 可能出现同时受到较大干扰的情况, 传输 的鲁棒性会受到较大影响。 而控制信令会对鲁棒性非常敏感。 控制信令的传输错误严 重影响系统性能。 另外, 相关技术中也没有小区间控制信令干扰信息交互和控制信令干扰消除的方 案。 发明内容 本发明提供了一种小区间信息的交互方案, 以至少解决相关技术中由于控制信令 小区间缺乏干扰信息交互而导致小区间干扰较大, 从而影响系统性能的问题。 根据本发明的一个方面, 提供了一种小区间信息的交互方法, 包括: 第一小区所 属网元确定干扰敏感的传输资源的位置, 其中, 干扰敏感的传输资源的位置包括: 第 一小区中控制信令的传输资源位置;

ABS可以和时域的指示一起二维, 也可以单独给一个频域指示, 如果是单独频域 指示, 则可以是所有传输时间间隔 (Transmission Time Interval, 简称为 TTI) 的。 本实施例通过小区间控制信令传输区域的配置信息的交互, 本小区可以将邻小区 发送控制信令的区域配置为数据信道, 或者在邻小区发送控制信令的区域上以低功率 或零功率发送信息, 从而避免对邻小区控制信道的干扰, 提高了鲁棒性。 下面通过具体实例说明本发明实施例的实现过程。 实例 1 本实施例提供了一种小区间信息的交互的具体实现方法, 图 4是根据本发明实施 例的实例 1的小区间信息的交互方法的流程图, 如图 4所示, 该方法包括如下的步骤 S402至步骤 S406。 步骤 S402, 小区 A确定一个或多个 UE的干扰敏感 (或描述为干扰强度高, 干扰 比重大, 干扰严重;)的传输资源位置, 例如, 可以是专有控制信令传输资源配置。 传输资源位置可以用 LTE/LTE-A已有的资源定义描述或其它新定义资源定义和表 示方法描述。例如, 以 RB-TTI为单位表示, 以 RB-Slot为单位表示, RB-Symbol为单 位表示, 或以 RE为单位表示, 下面对这几种单位分别进行说明。
RB-Symbol: 图 5是根据本发明实施例的 RB-Symbol的示意图, 如图 5所示, 为 在频域上包括协议规定的一个 RB含有的子载波数, 在时域上包括一个 OFDM符号的 二维单元。
