Some of the access nodes can be directly connected. The link between the directly connected access nodes is called a backhaul link, and the link between the AP and the terminal is called an access link.

- 3GPP LTE-A can provide downlink 100 Mbit/s and uplink 50 Mbit/s peak rates in a 20 MHz spectrum bandwidth, improving the performance of cell edge users and improving the cell. Capacity, and system delay is reduced. However, to achieve such high peak rate and cell throughput, more bandwidth is needed. Due to the tight spectrum resources, some or all of the required bandwidth is only available according to the existing spectrum allocation method. In the higher frequency band, the path loss and the penetration loss of the band are large, and it is difficult to achieve good coverage. To solve the above problem, 3GPP introduces the key technology of the LTE-A system, the relay technology, A wide range of concerns from major operators and equipment vendors.

The DeNB2 is about 35 kilometers away from the RN.

回程链路资源的预配置方法和设备、 预配置信息提供方法 技术领域
本发明涉及无线通信技术, 尤其涉及一种回程链路资源的预配置方法 和设备、 预配置信息提供方法。 背景技术
对于长期演进 ( LTE, Long Term Evolution )技术或者演进的长期演进 ( LTE-A, Long Term Evolution-advanced )技术来说 , 目前的接入节点 ( ΑΡ, Access Point )主要有以下几种: 增强的宏小区基站(enhanced Node Base Station ), 中继节点(RN, Relay Node )、 微微小区基站(Femto NB )、 微小 区基站(Pico NB )和家庭基站(home NB )。 这些接入节点之间有的能够直 接相连, 其中能够直接相连的接入节点之间的链路称作回程链路(backhaul link ), AP和终端之间的链路称为接入链路。
以 RN为例, 随着现在无线通信技术的不断发展, 3GPP LTE-A能够在 20MHz频谱带宽下提供下行 100Mbit/s与上行 50Mbit/s的峰值速率, 改善 了小区边缘用户的性能, 提高了小区容量, 并且降低了***延迟, 然而要 实现如此高的峰值速率和小区吞吐量就需要有更大的带宽, 由于频谱资源 曰益紧张, 根据现有的频谱分配方法, 需要的部分或全部带宽只能在更高 的频段上, 而该频段路损和穿透损都较大, 很难实现好的覆盖, 为解决上 述问题, 3GPP引入了 LTE-A***的关键技术一一中继技术, 受到了各大运 营商和设备商的广泛关注。 所谓中继技术, 简单的说, 就是在下行方向上, 基站发给终端的信号不直接发给终端, 而是先发给一个 RN, 然后再由 RN 转发给终端; 在上行方向上, 终端的上行信号也不是直接发给基站, 而是 先发给一个 RN, 然后再由 RN转发给基站。 所谓回程链路是指服务于 RN
与基站之间的通信链路,接入链路是 RN与其下属终端之间的链路,服务于 RN的基站称为施主基站( DeNB, Donor evolved Node B )。 RN主要有以下 几种应用场景: 为实现无缝覆盖, 降低部署成本, 在偏远的农村部署 RN; 为增强覆盖和用户吞吐量的同时提高频谱效率, 而部署的城市热点; 在文 物古迹等特殊场景, 出于保护文物的目的, 在室内部署 RN; 为了减少高速 移动的一组终端进行频繁的小区切换, 在交通工具上(如火车、 大巴等) 部署 RN等。
回程链路在 LTE/LET-A中通常是无线的,在如下场景: 在偏远的地区、 临时热点覆盖区域、 应急网络部署、 文物古迹、 游牧状态的接入点等, 由 于部署有线连接的成本太高、 或无法估计终端位置而提前进行有线覆盖、 或为避免部署有线网络对文物造成破坏、 或有线通信中断, 都无法通过有 线连接进行有效覆盖, 而无线链路可以迅速有效地提供服务, 因此需要为 回程链路分配频率资源, 从而进行无线连接。
针对回程链路使用的资源问题, 目前主要根据频谱管理组织的规定, 将一部分授权分配给 LTE/LTE-A***的频谱资源用于回程链路连接。 在这 种分配方式下, 回程链路与接入链路复用分配的频谱资源, 难免会造成两 个链路之间的相互干扰, 并且在一定程度上,还会对 AP所连接的当前基站 的接入链路的容量和服务质量造成影响。 为减小这种干扰和影响, 在认知 无线电***中, 回程链路可以通过使用空闲频谱, 来避免回程链路与接入 链路之间的相互干扰和对无线接入链路的容量或者服务质量造成的影响, 所述空闲频谱是指在一定区域和时间上未被授权用户使用的主***频谱资 源, 这时需要解决回程链路资源预配置的问题。 发明内容
