本发明提供了一种用于 TD SCDMA系统等 IDD系统中, 对特殊突发进 行功率控制的方法。 对特殊突发与业务数据采用不同的功率控制参数值, 解 决了现有功率控制机制下, 特殊突发和业务数据釆用相同的功率控制参数值 导致特殊突发对其他用户信号干扰的问题。
本发明对特殊突发采用与业务数据不同的方法进行功率控制。 在通信系 统中, 由于进行的通信内容不同, 因此对业务数据的性能要求也是不同的, 不同业务要求的目标误块率也不相同, 因此根据不同业务设置不同的功率控 制参数值。 而由于特殊突发的发送方式和内容都是固定的, 因此对特殊突发 的性能要求也是固定的,因此特殊突发可以采用与业务数据不同的控制参数, 而—目.参数较为固定。
其中, 功率控制参数值, 既可以是目标误块率, 也可以是目标质量。 由于特殊突发的功率控制参数值相对固定, 对于参数值的确定可以采用 默认的数值, 也可以由网络端设备决定, 并通过空中信令通知给终端。

对于下行信号,也就是由网络端设备发送到终端的信号,所述方法包括: 步骤 1, 网络端设备预先将业务数据的功率控制参数值和特殊突发的功 率控制参数值分别通知终端。 业务数据的功率控制参数值通过专有信令的方 式通知终端; 特殊突发的功率控制的通知方式既可以采用默认取值的方式, 也可以通过公共信令或专有信令传输。
步骤 2, 如果终端检测到的是业务数据, 终端采用业务数据的功率控制 参数值对下行信号进行功率控制。
歩骤 3, 如果终端检测到的是特殊突发, 终端采用特殊突发的功率控制 参数值对特殊突发进行功率控制。
对于上行信号,也就是由终端发送到网络端设备的信号,所述方法包括: 步骤 1, 如果网络端设备检测到的是业务数据, 网络端设备采用业务数 据的功率控制参数值对上行信号进行功率控制。
步骤 2, 如果网络端设备检测到的是特殊突发, 网络端设备采用特殊突 发的功率控制参数值对特殊突发进行功率控制。 其中, 特殊突发的功率控制 参数值与业务数据的功率控制参数值不相等。
所述方法实施例是与所述装置实施例相对应的, 在方法实施俩中未详细 描述的部分参照装置实施例中相关部分的描述即可, 在装置实施例中未详细 描述的部分参照方法实施例中相关部分的描述即可。
在本发明各方法实施例中, 所述各步骤的序号并不能用于限定各歩骤的 先后顺序, 对于本领域普通技术人员来讲, 在不付出创造性劳动的前提下, 对各步骤的先后变化也在本发明的保护范围之内。
以上所述是本发明的优选实施方式, 应当指出, 对于本技术领域的普通 技术人员来说, 在不脱离本发明所述原理的前提下, 还可以作出若千改进和 润饰, 这些改进和润饰也应视为本发明的保护范围。
