一种资源协作的方法及系统 技术领域
本发明涉及通信领域， 特别是指一种资源协作的方法及系统。 背景技术
B3G/4G的研究目标是： 汇集蜂窝、 固定无线接入、 游牧、 无线区域网 络等接入系统， 结合全 IP网络， 在高速和低速移动环境下分别为用户提供 峰值速率达 100Mbps及 lGbps的无线传输能力， 并且实现蜂窝通信系统、 区域性无线网络、 广播、 电视卫星通信的无缝衔接， 最终实现 "任何人在 任何时间、 任何地点与其他任何人进行任何方式的通信"。 中继（Relay )技 术既可以增加小区覆盖也可以增加小区容量， 使得中继技术可以作为一项 有效的措施应用起来。 引入中继技术后， 会引发比较多的问题， 如资源利 用便是需要深入研究的问题。
时频资源管理对于正交频分复用 （ OFDM , Orthogonal Frequency Division Multiplexing )通信系统非常重要， 特别是对于引入中继站（RS, Relay Station )的通信系统。在两跳通信系统中，一般情况下为用户终端（ UT , User Terminal )传输的数据，首先由基站（ BS , Base Station )在中继区（ Relay Zone )发射给 RS , 再由该 RS在接入区 （ Access Zone )发射给 UT。 这样， 所占用的时频资源是原来的两倍， 导致了资源利用率的下降。
协作技术是多跳通信系统中一种宏观的或分布式的多输入多输出 ( MIMO , Multiple-Input Multiple- Out-put ) 通信系统， 可以应用于接入 ( Access )或中继的上下行链路中。协作技术类似于相邻 BS之间的宏分集， 是在基地台（ MR-BS, Multihop Relay Base Station )小区中利用 BS与各 RS 之间的协作发射实现的， 通过利用不同 BS和 RS的发射天线来发送相关的
信号， 实现协作分集。 通过协作技术， 空间分集作用可以为链路提供更好 的误码率（ BER, Bit Error Rate ) /误块率（ BLER, Block Error Rate )性能， 同时空间复用可以为通信系统带来更高的频谱效率。
协作可以是多个发射源， 即多点。 对于引入 RS的 BS内的资源协作可 以看作是 BS内多点资源协作； 对于多个 BS间的资源协作可以看作是 BS 间多点协作。 BS间多点协作中可以包括 BS内多点资源协作， 即其中的 BS 引入了 RS, 也就是 BS内多点资源协作与 BS间多点资源协作的组合。
目前， 对于 BS和 RS的研究是一个热点，但对于 BS与 RS之间、 多个 RS之间、 多个 BS之间的资源协作的研究较少。 目前的通信系统都是基于 频率进行资源协作的方案， 但对于频率资源存在信道质量信息 （CQI , Channel Quality Indicator )反馈准确性和调度的问题， 也就是说， 对于协作 的频率资源内的 CQI并不能真实反映信道条件， 而非协作的频率资源内的 CQI 能够反映信道条件， 这导致通信系统在进行下次调度的时候不能依据 CQI准确地进行资源分配。 发明内容
有鉴于此， 本发明的主要目的在于提供一种资源协作的方法及系统， 有效解决频率资源协作导致的 CQI不准确的问题。
为解决上述技术问题， 本发明的技术方案是这样实现的：

根据来自高层的信令确定是否需要对协作时间资源与非协作时间资源 的比例进行调整； 或者，
根据设定规则确定是否需要对协作时间资源与非协作时间资源的比例 进行调整。
所述时间资源以正交频分复用 OFDM符号、 或时隙、 或子帧、 或无线 帧、 或超帧为时间单位；
所述一个时间窗口中协作时间资源与非协作时间资源的比例， 是： 所 述时间窗口中用于资源协作的时间单位数量与用于非资源协作的时间单位 数量的比值。

所述 BS内多点资源协作为： BS与该 BS覆盖范围内的多个 RS间的资 源协作， 或者， 一个 BS覆盖范围内的多个 RS间的资源协作；
所述 BS间多点资源协作为： 多个 BS间的时间资源协作。
该方法进一步包括： 动态、 或半静态、 或静态配置所述时间窗口的大 小。
一种资源协作的系统， 该系统包括： 至少两个协作节点， 协作资源与 非协作资源采用时分形式， 各协作节点具有相同时间长度的时间窗口， 用 于选择时间窗口中的相同时间资源进行资源协作。
所述协作节点进一步用于：
通过协商或根据收到的高层配置通知选择协作时间资源； 和 /或， 通过协商或根据收到的高层配置通知调整一个时间窗口中协作时间资 源与非协作时间资源的比例。
所述协作节点至少包括： 处理模块， 用于在时间窗口中选择与其他协 作节点相同的时间资源进行资源协作。
所述协作节点进一步包括： 判断模块和调整模块， 其中， 整时， 通知调整模块进行调整；
所述调整模块用于对时间窗口中协作时间资源与非协作时间资源的比 例进行自适应调整；
所述处理模块， 用于根据调整后的比例在时间窗口中选择与其他协作 节点相同的时间资源进行资源协作。
本发明方案中， 各协作节点具有相同时间长度的时间窗口， 选择时间 窗口中的相同时间资源进行资源协作， 因此， 协作资源与非协作资源是时 分形式的， 通过本发明提供的筒单易行的方案， 合理划分资源， 有效地解 决了频率资源协作所导致的 CQI不准确的问题,使得调度不再受不准确 CQI 的影响。 准确的 CQI将使得编码、 调制、 资源映射等更加适合链路情况， 既提高了单点到单点的链路性能， 也提高了整个系统的吞吐量。

协作节点之间可以根据协商结果来确定是否需要对协作时间资源与非 协作时间资源的比例进行调整； 也可以根据来自高层的信令确定是否需要
步骤 502: 采用调整后的比例在时间窗口中进行协作时间资源的配置。 协作时间资源与非协作时间资源的比例可以由各协作节点之间的协商 来确定， 也可以根据来自高层的信令来确定。 协作时间资源配置在时间窗 口中的位置， 可以根据设定规则进行选择； 也可以根据协作节点之间的协 商结果进行选择； 还可以根据高层配置进行选择。
步骤 503: 采用原有比例在时间窗口中进行协作时间资源的配置。协作 时间资源配置在时间窗口中的位置， 可以根据设定规则进行选择； 也可以 根据协作节点之间的协商结果进行选择； 还可以根据高层配置进行选择。
图 1至图 4的 4种场景中， 设置时间窗口的大小为 3个子帧， 协作时 间资源与非协作时间资源的比例均为 1 :2。 实际应用中， 也可以定义时间窗 口的其他大小， 例如， 时间窗口的大小可以是 10个子帧、 32个子帧等等，
2:8、 10:22等。
例如， 如果某个 BS覆盖范围内有 2个 RS, 即 RS1、 RS2, 时间窗口大 小为 10个子帧， 子帧的单位为 lms, 并且在第 1个时间窗口中协作时间资 源与非协作时间资源的比例为 2:8; 在第 2个时间窗口中协作时间资源与非 协作时间资源的比例为 3:7。 这样， BS、 RSI , RS2进行资源协作时， 在第 1个时间窗口中， BS、 RSI , RS2采用 2:8的比例对协作时间资源进行配置，
如选择该时间窗口中的第 2个子帧和第 7个子帧作为协作时间资源， 该时 间窗口中的其他子帧不进行资源协作； 在第 2个时间窗口中， BS、 RS1、 RS2采用 3:7的比例对协作时间资源进行配置，选择该时间窗口中的第 2个 子帧、 第 6个子帧和第 9个子帧作为协作时间资源， 该时间窗口中的其他 子帧不进行资源协作。 选择作为协作时间资源的子帧时， 可以根据设定规 则进行选择； 也可以根据协作节点之间的协商结果进行选择； 还可以根据 高层配置进行选择。
图 6为本发明中资源协作系统结构示意图， 如图 6所示， 该系统包括： 至少两个协作节点， 如第一协作节点和第二协作节点， 各协作节点具有相 同时间长度的时间窗口， 用于选择时间窗口中的相同时间资源进行资源协 作。
各协作节点进一步用于： 通过协商或根据收到的高层配置通知选择协 作时间资源； 和 /或， 通过协商或才艮据收到的高层配置通知调整一个时间窗 口中协作时间资源与非协作时间资源的比例。
协作节点至少包括： 处理模块， 用于在时间窗口中选择与其他协作节 点相同的时间资源进行资源协作。 协作节点进一步包括： 判断模块和调整 要调整时， 通知调整模块进行调整； 调整模块用于对时间窗口中协作时间 资源与非协作时间资源的比例进行自适应调整； 处理模块， 用于根据调整 后的比例在时间窗口中选择与其他协作节点相同的时间资源进行资源协 作。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的保 护范围。
