Description
频谱处理的方法、 基站、 用户设备及系统 技术领域
本发明涉及通信技术领域, 尤其涉及一种频谱处理的方法、 基站、 用户 设备及系统。 背景技术
随着通信技术的不断发展, 运营商正在逐渐用长期演进(Long Term Evolut ion, 简称 LTE )网络替代全球移动通信 Globa l Sys tem for Mobi le communicat ions , 简称 GSM )网络。 运营商在部署 LTE网络时, 在部分话务密 集区域, 保留少量的 GSM的网络频谱, 其余 GSM的网络频谱全部划分给 LTE 使用。 通常,在 GSM基站周围设置一个緩冲区域( buffer zone ) , 以防止 GSM 系统与 LTE系统之间的信号相互干扰。 例如: 原先有 20M的 GSM网络频谱, 现在为 GSM小区保留 3. 6M, 緩冲区域 5M, 剩余的 11. 4M的网络频语全部划分 给 LTE 小区使用。 为了进一步提高网络频谱的利用率, 现有技术中提供了下 述方式将緩冲区域划分给 LTE系统使用。
在用户设备(User Equi pment , 简称 UE )接入 LTE小区的过程中, 如果 LTE 频谱与 GSM频谱存在重叠 (即存在緩冲区域), 则基站通知 UE进行检测, 检测 UE是否能够忍受 GSM信号的干扰(又称异系统测量)。 如果 UE能够忍受, 则基 站允许 UE使用緩冲区域的频谱。
在实现上述频谱处理的过程中, 发明人发现现有技术中至少存在如下问 题: 现有技术需要 UE具有异系统测量能力, 即检测是否能够忍受 GSM信号的 能力, 如果 UE不具备异系统测量能力则无法使用緩冲区域频谱。 当 UE具有 异系统测量能力时, 在进行异系统测量的过程中, 不仅提高 UE的耗电, 而且 发送测量报告(异系统测量结果)会消耗 LTE小区原本就紧缺的空口资源。 发明内容

1、 当所述平均值大于预设阈值, 确定所述第一小区使用所述交叠频谱。 平均值大于预设阈值, 表示交叠频谱的信道质量高于预设的信道质量, 可以使用交叠频谱进行通信。
2、 当所述平均值小于预设阈值, 确定所述第一小区使用所述第一小区的 频带中除交叠频谱以外的部分。

进一步的, 每个子带信道质量参数可以是子带信道质量指示 Channel Qua l i ty Indi cator。 通过子带信道质量指示对子带信道质量参数进行量化, 进而提高频谱处理的精确度。
下面通过一个使用场景作进一步说明:
如表 1所示, 交叠频谱为 0M-20M, —个子带信道的带宽为 2M, 整个信道 频语被划分为 10个子带信道。 如果交叠频谱占用 0-5M的频谱, 则与之对应 的子带信道有三个, 分别为 0M-2M、 2M-4M、 4M-6M。 在接收到 UE发送的十个 子带信道质量参数后, 基站从十个子带信道质量参数中找到 0M-2M、 2M-4M、
4M-6M这三个频段分别对应的子带信道质量参数。 如表 1所示, 0M-2M的子 带信道质量参数为 6、 2M-4M的子带信道质量参数为 6、 4M-6M的子带信道质 量参数为 3。 计算上述三个子带信道质量参数的平均值(6+6+3) /3=5。 如果 预设阈值为 4, 则由于 5大于 4, 因此确定使用交叠频谱。 计算其余七个子带 信道质量参数的平均值(6+7+8+8+8+7+6) /7=50/7«7.1, 由于交叠频语对应 的子带信道质量的第一平均值为 5, 第二平均值与第一平均值的之差为 7.1-5=2。 如果预设门限为 3, 则由于 2<3, 即第二平均值与所述第一平均值 之差小于预设门限, 因此确定所述第一小区使用所述交叠频谱。
