为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本发 明实施例中的附图， 对本发明实施例中的技术方案进行清楚、 完整地描述， 显然， 所描述的实施例是本发明一部分实施例， 而不是全部的实施例。 基于 本发明中的实施例， 本领域普通技术人员在没有作出创造性劳动前提下所获 得的所有其他实施例， 都属于本发明保护的范围。
图 1为本发明基站实施例一的结构示意图。 图 2为本发明基站实施例一 的信令流程图一。 图 2A为本发明基站实施例一的信令流程图二。本实施例的 执行主体可以为用户设备 UE的主基站， 该主基站可以通过软件和 /或硬件实 现。 本实施例的方案应用在主基站、 辅基站和用户设备之间， 实现基站间载 波聚合的测量间隔配置。 如图 1所示， 本实施例的基站 10， 包括： 获取模块 101和发送模块 102， 其中， 获取模块 101， 用于获取校正的测量间隔信息； 其中，校正的测量间隔信息为根据测量间隔信息和所述基站与用户设备 UE的 辅基站间的定时偏差获取，测量间隔信息用于所述基站指示 UE在测量间隔 信息指示的测量间隔期间进行测量； 发送模块 102， 用于将校正的测量间隔 信息发送给辅基站， 用于辅基站在校正的测量间隔信息指示的测量间隔期间 停止对 UE进行调度。
具体地， 如图 2所示， 基站 10的发送模块 102将获取模块 101获取到的 校正的测量间隔信息发送给辅基站。 辅基站接收到校正的测量间隔信息后， 在校正的测量间隔期间不调度该 UE, 即在校正的测量间隔期间内， UE和辅基 站间不会有信息或数据的传递，校正的测量间隔信息为根据测量间隔信息和定 时偏差计算得到的。对于基站间载波聚合， UE的主基站与辅基站可能不同步， 定时偏差指的是 UE的主基站与 UE的辅基站间的定时偏差，或者也可以理解 为主基站的小区与辅基站的小区间的定时偏差。定时偏差一般是相对于 UE的 主基站的主小区 （Primary Cell, 简称 PCell) 的时间偏差， 也就是主小区与辅 基站的任意小区间的时间偏差。 UE的主基站的服务小区可以被看成是主小区 组 （Master Cell Group) ， 每个辅基站上的所有服务小区可以分别被看成是辅 小区组 （Secondary Cell Group) 。 对于小区组来说， 定时偏差指的是， 主小 区组与辅小区组间的定时偏差。 需要说明的是， 本发明实施例以主基站和辅 基站来进行描述， 但是也适用于小区组的说法。
如图 2所示， 在给辅基站发送校正的测量间隔信息的同时或之前或之后， 基站 10的发送模块 102可以通过 RRC连接重配置消息发送测量间隔信息给 UE， UE收到之后回复响应消息 RRC连接重配置完成消息给主基站， UE在 测量间隔信息指示的测量间隔期间不接收主基站和辅基站上的数据而进行测 量。
上述方法避免了如果辅基站在主基站指示的测量间隔期间调度该 UE，UE 由于正在该测量间隔期间内进行测量而不能接收或发送数据， 从而造成空口 资源的浪费。
当主基站决定释放 UE的测量间隔配置时， 主基站也发送通知给辅基站， 从而辅基站释放测量间隔配置，在调度 UE时不再受到测量间隔的限制，如图 2A所示， 主基站可以通过测量间隔通知消息或 UE信息更新消息将释放测量 间隔配置的消息发送给辅基站， 主基站可以通过 RRC连接重配置消息将释放 消息发送给 UE, 发送给 UE以及辅基站不限制先后顺序。
可选地， 发送模块 102， 具体用于：
通过通知消息或更新消息将校正的测量间隔信息发送给辅基站。
具体地， 发送模块 102可以通过测量间隔通知（Measurement gap notify ) 消息或 UE信息更新（UE information update)消息向 UE的辅基站发送校正的 测量间隔信息。
本实施例，通过基站获取根据测量间隔信息和用户设备 UE的主基站与所 述 UE 的辅基站间的定时偏差计算得到的校正的测量间隔信息， 发送给辅基 站， 用于辅基站在所述校正的测量间隔信息指示的测量间隔期间停止调度所 述 UE, 实现了辅基站在用户设备测量间隔期间停止调度该 UE, 避免空口资 源的浪费， 提高网络的传输效率， 解决了针对基站间载波聚合， 如何设计测 量机制的问题。

根据测量间隔信息和定时偏差计算校正的测量间隔信息； 或，
接收 UE发送的根据测量间隔信息和定时偏差计算得到的校正的测量间 隔信息。
具体地， 如图 3所示， 基站 10的获取模块 101根据测量间隔信息和定时 偏差计算校正的测量间隔信息， 将计算后的校正的测量间隔信息通过发送模 块 102发送给辅基站其中， 定时偏差具体的获取方法可以是主基站自己监测 主基站和辅基站的小区来获得定时偏差， 或者主基站通过 UE来获取定时偏 差， 图 3中其余步骤与实施例一中相同， 此处不再赘述。
可选地， 发送模块 102， 还用于： 向 UE发送无线资源控制 RRC连接重 配置消息， RRC连接重配置消息包括测量间隔信息；
获取模块， 具体用于： 接收 UE发送的 RRC连接重配置完成消息， RRC 连接重配置完成消息包括 UE根据测量间隔信息和定时偏差计算得到的校正 的测量间隔信息。
具体地， 如图 4所示， 基站 10的获取模块 101接收 UE根据测量间隔信 息和定时偏差计算得到的校正的测量间隔信息，可以通过接收 UE发送的 RRC 连接重配置完成消息获取到校正的测量间隔信息， 由发送模块 102转发给辅 基站， UE发送校正的测量间隔信息之前， 如果 UE配置了辅基站， UE获取 辅基站与主基站间的定时偏差（此步骤与接收携带测量间隔信息的 RRC连接 重配置消息不分先后顺序）， 在接收校正的测量间隔信息， 还可以向 UE发送 包括测量间隔信息的 RRC连接重配置消息， 其余步骤与实施例一中相同， 此 处不再赘述。
可选地， 发送模块 102， 还用于：
发送请求消息给 UE, 请求消息用于请求 UE获取到定时偏差后上报给基 站； 或，
向 UE发送包括指示信息的消息， 指示消息用于请求 UE上报定时偏差； 或，
获取模块 101， 还用于通过与 UE预先协商好的上报定时偏差的时机， 接 收 UE上报的定时偏差。
具体地， 如图 5所示， 基站的发送模块 102在计算校正的测量间隔信息 之前， 发送请求消息， 比如定时偏差请求消息， 给 UE, 用于请求 UE将获取 到的定时偏差上报给主基站， 定时偏差请求消息还可以包括目标小区标识或 目标基站标识（在本实施例中，上述目标小区标识可以是 UE的辅基站的小区 标识， 上述目标基站标识可以是辅基站标识） ， UE通过请求响应消息携带定 时偏差发送给主基站， 例如通过定时偏差请求响应消息携带。
在本实施例中， 定时偏差针对两个小区而言。对于一个 UE来说， 同一个 基站内的服务小区是同步的。 一种获取基站与目标基站的小区的定时偏差的 实现方式是， 主基站的小区使用主小区 PCell或主基站的任意一个服务小区， 目标基站是当前 UE的辅基站或定时偏差请求消息里指定的基站，目标基站的 小区使用指定的目标小区或目标基站的任意一个服务小区。 也就是， 比如： UE 获取主基站的任意一个服务小区与目标基站的任意一个服务小区的定时 偏差； 或者 UE获取主基站的主小区 PCdl与目标基站的任意一个服务小区的 定时偏差， 或者 UE获取主小区 PCell或主基站的任意一个服务小区与指定的 目标小区的定时偏差等方法。
或者， 如图 6所示， 基站 10的发送模块 102也可以通过在发送给 UE的 消息中包括指示信息； 指示信息用于请求 UE上报定时偏差， 如通过 RRC连 接重配置消息中的测量配置信息或辅小区 /辅基站增加信息里携带指示信息， 请求 UE上报定时偏差， UE通过测量报告或 RRC连接重配置完成消息携带 定时偏差发送给基站； 或者， 指示信息也可以是隐式的， 比如， 通过与 UE预 先协商好的上报定时偏差的时机，获取模块 101接收 UE上报的定时偏差，例 如， 当 UE收到增加辅小区 /辅基站请求时， UE 自动在响应消息 （RRC连接 重配置完成消息） 里携带当前增加的辅小区 /辅基站与 PCdl的定时偏差。
考虑到各 UE的位置不同， 导致无线信号到达各 UE的传输时延不同， 因 此从 UE获取定时偏差更准确。
可选地， 校正的测量间隔信息与测量间隔信息包含相同的测量周期； 校 正的测量间隔信息包含第一偏移量， 测量间隔信息包含第二偏移量， 第一偏 移量为第二偏移量与定时偏差相加后， 与测量周期取模后的值。
可选地， 测量间隔信息指示的测量间隔期间包括连续 M个子帧的时间 间隔， M为正整数；
校正的测量间隔信息指示的测量间隔期间包括连续 N个子帧的时间间 隔， N为正整数， 其中， N个子帧包含 M个子帧。
上述连续 M个子帧的时间间隔、 连续 N个子帧的时间间隔分别为从测 量周期的第一偏移量、 第二偏移量开始的。
在本实施例中，上述 N个子帧包含 M个子帧可以指 N个子帧对应的时间 覆盖 M个子帧对应的时间； 也可以指 M个子帧为 N个子帧的子集。
本发明实施例中， 以 M=7， N=6为例进行说明， 需要说明的是， 这里只是 举例说明， 本发明实施例并不限于此。
具体地， 测量间隔可以分为两种模式， 一种是模式 0: 40毫秒（4个帧长 度）为一个测量周期， 其中一个 6毫秒 （6个子帧） 的测量间隔； 另一种是模 式 1 : 80毫秒 （8个帧长度） 为一个测量周期， 其中一个 6毫秒的测量间隔。
如图 7所示， 在 LTE系统里， 时域上被分为帧和子帧， 一个帧占用 10 毫秒， 1个帧包含 10个子帧， 每个子帧 1毫秒。 主基站和辅基站不同步， 指 的是在同一时刻， 主基站和辅基站的帧号、 子帧号不相同和 /或子帧边界不对 齐。 定时偏差就是指在同一时刻主基站和辅基站之间的帧号、 子帧号的差值 (由于子帧边界不对应， 差值还可以有小数） ， 或者说在主基站上的某个帧 号、 子帧号对应的时间， 与辅基站上相同的帧号、 子帧号对应的时间之间的 差值。
传输的定时偏差可以是实际定时偏差的向下取整或向上取整， 以便于传 输。传输的定时偏差可以有不同的格式， 比如使用 2个整数，第一个是帧差 a, 第二个是子帧差 b， 或者使用 1个整数表示相差多少 （假如为 c) 个子帧或者 说毫秒， 实际上， c = 10*a + b， 当然也可以上报更细粒度的定时偏差， 比如 微秒（μ s), 但是相应的信令开销更大。本发明实施例里均以采用单位为子帧的 向下取整的 1个整数的方法为例来进行说明， 其他的类推。
获取到定时偏差后， 计算校正的测量间隔信息的公式如下：
校正的测量间隔值 = (测量间隔值 +定时偏差） mod 40或 80
校正后， 校正的测量间隔信息与测量间隔信息包含相同的测量周期。 如 果测量间隔模式是模式 0 (40毫秒的测量周期） ， 则上述公式使用 40取模； 如果测量间隔模式是模式 1 (80毫秒的测量周期）， 则上述公式使用 80取模。
校正的测量间隔信息包含的第一偏移量即为上文公式中的校正的测量间隔 值； 测量间隔信息包含的第二偏移量即为上文公式中的测量间隔值。
发送给 UE 的测量间隔是从测量间隔信息指示的第二偏移量即测量间隔 值开始连续 6个子帧为测量间隔期间， 然而校正后的测量间隔， 从校正的测 量间隔信息指示的第一偏移量即校正的测量间隔值开始，连续 7个子帧为测量 间隔期间， 以避免子帧边界不对齐引起的问题。
例如： 如图 8所示， 实际定时偏差是： （105*10+l.x) _ 30*10=751.x， 其中
X是子帧边界的偏差 （帧 105子帧 1边界与帧 30子帧 0边界的偏差） ； 以主 小区的帧 30的时间点为起始时间。 主小区的帧 30和目标小区的帧 105为任 意取值， 本发明对此不做限定。 一种方式为， 该主小区的帧 30和目标小区的 帧 105对应的时间相同或临近。
传输的定时偏差， 是实际定时偏差的向下取整， 则是 751。
如果测量间隔模式是模式 0 (测量周期为 40毫秒） ， 测量间隔信息的偏 移量是 21 (即第二偏移量） （对应的测量间隔期间见主小区的灰色部分） （测 量周期起始为帧 28开始， 测量周期起始为帧号 mod 4=0， 或帧号 mod 8 = 0 (对应模式 1 )开始），则校正后的测量间隔信息包含的第一偏移量为：(751+21) mod 40 = 12 (对应的校正的测量间隔期间见目标小区的灰色部分） （周期起 始从帧 104开始） ， 其测量间隔期间持续 7个子帧， 测量间隔模式也是模式 0 (测量周期为 40毫秒） 。
本实施例，通过基站获取基站自己根据测量间隔信息和主基站与 UE的辅 基站间的定时偏差计算校正的测量间隔信息，或者 UE计算的校正的测量间隔 信息， 发送给辅基站， 用于辅基站在校正的测量间隔信息指示的测量间隔期 间停止调度所述 UE,实现了辅基站在用户设备测量间隔期间停止调度该 UE, 避免空口资源的浪费， 提高网络的传输效率， 解决了针对基站间载波聚合， 如何设计测量机制的问题。
