本申请要求于 2011 年 01 月 10 日提交中国专利局、 申请号为 201110004191.5、发明名称为"测量间隙的配置方法和通信装置"的中国专利申 请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及无线通信技术领域， 特别涉及一种测量间隙的配置方法和通 信装置。 背景技术
OTDOA ( Observed Time Difference Of Arrival, 观察到达时间差）是一种 常见的定位技术， 其原理是终端通过测量三个以上不同基站发送的 PRS ( Positioning Reference Signal,定位参考信号）的达到时间差 RSTD( Reference Signal Time Difference,参考信号时间差），来获取不同基站到达终端的距离之 差， 从而达到定位的目的。
在上述定位过程中， 终端进行异频测量时， 需要从定位中心获取定位辅 助数据， 并从服务小区的基站获取间隙配置信息。 其中， 定位辅助数据包括 测量小区的标识（或称参与定位的异频小区）及测量小区的 PRS信息， PRS 信息包括 I-PRS (定位参考信号索引 )和 n-PRS (定位时隙的长度）， 终端通 过 PRS信息能够确定测量小区的定位时隙 （occasion )。 间隙配置信息包括间 隙样式 ( gap pattern )和间隙偏移量 ( gapOffset ), 终端通过间隙配置信息能够 确定异频测量的测量间隙。 为了使终端在测量间隙内检测到测量小区的 PRS , 也即为使得测量间隙能够覆盖定位时隙， 基站需要配置正确的间隙配置信息。
在现有技术中， 间隙偏移量配置不合理会使终端在测量间隙内检测不到 测量小区的 PRS , 影响 PRS的检测性能。 发明内容

参见图 1-a, 本实施例提供了一种测量间隙的配置方法， 该配置方法可以 由终端或定位中心执行， 包括：
S11 : 根据参与定位的小区的 PRS信息确定间隙偏移量， 或者根据参与定 位的小区的 PRS信息或参与定位的小区的频率信息确定用于获取间隙偏移量 的信息；
S12: 将间隙偏移量或用于获取间隙偏移量的信息发送给服务小区的基 站。
本实施例通过根据参与定位的小区的 PRS信息确定间隙偏移量的方案， 提高了终端在测量间隙内检测到参与定位的小区的 PRS的概率， 从而提高了 PRS的检测性能。 参见图 1-b, 本实施例提供了另一种测量间隙的配置方法， 该配置方法可 以由终端或定位中心执行， 该配置方法包括：
S21 : 才艮据参与定位的小区的 PRS信息， 确定间隙偏移量；
其中， 异频测量时， 参与定位的小区是指参与定位的异频小区， 或称测 量小区。
S22: 将间隙偏移量发送给服务小区的基站。
其中， 间隙偏移量还用于指示基站终端需要进行异频测量。
本实施例通过根据参与定位的小区的 PRS信息， 确定间隙偏移量， 将间 隙偏移量通知服务小区的基站， 这种根据参与定位的小区的 PRS配置间隙偏 移量的方案，提高了终端在测量间隙内检测到参与定位的小区的 PRS的概率， 从而提高了 PRS的检测性能。 参见图 2, 本实施例提供了另一种测量间隙的配置方法， 该方法定位中心 或终端将确定好的间隙偏移量发送给基站， 包括：
100: 定位中心将 RSTD异频测量的定位辅助数据发送给终端。
所谓 RSTD异频测量， 是指终端对与服务小区频率不同的测量小区进行 RSTD测量。 其中， RSTD异频测量的定位辅助数据包括测量小区的标识和测 量小区的 PRS信息等。 PRS信息包括 I-PRS (定位参考信号索引）和 n-PRS (定位时隙的长度）， 例如， n-PRS的值可为 1、 2、 4、 6。
101 : 终端或定位中心才艮据测量小区的 PRS信息， 确定间隙偏移量。
本步骤可以包括：
101a: 确定 I-PRS对应的 PRS周期和 PRS偏移。
例如 , 可以才艮据表 1所示的 PRS子帧配置表 ( Positioning reference signal subframe configuration ), 确定 I-PRS对应的 PRS周期和 PRS偏移。
表 1
Figure imgf000007_0001
101b: 根据 PRS周期和 PRS偏移， 确定定位时隙 （occasion ) 的起点。 定位时隙在第一个 PRS 周期的起点位置对应的 系统帧号 SFN=FLOOR(PRS偏移 /10), 起点位置对应的子帧号 subframe= PRS偏移 mod 10, 定位时隙在其他 PRS周期的起点位置对应的系统帧号， 与第一个 PRS周 期的起点位置对应的系统帧号之间的子帧数， 相差该其他 PRS周期包括的子 帧数， 定位时隙在其他 PRS周期的起点位置对应的子帧号与第一个 PRS周期 的相同。 例如， I-PRS=1 个子帧时， PRS偏移是 1个子帧， PRS周期是 160 个子帧， 定位时隙的起点在（系统帧号 0, 子帧号 1 )、 (系统帧号 16, 子帧号 1 )、 （系统帧号 32, 子帧号 1 ) …等子帧上。 101c: 根据定位时隙的起点、 定位时隙的长度 n-PRS、 以及预设的测量间 隙持续子帧的数量， 确定测量间隙的起点。
根据定位时隙的起点和定位时隙的长度 n-PRS,确定定位时隙的范围；根 据预设的覆盖规则和测量间隙持续子帧的数量， 确定测量间隙的范围， 并将 测量间隙的范围的起点作为测量间隙的起点， 其中， 覆盖规则为测量间隙持 续范围内包括定位时隙， 或者测量间隙持续范围内包括定位时隙及定位时隙 的前后各预留的一个子帧， 以预留出异频测量的切换时间， 例如， 异频测量 的切换时间<0.51118。
其中， 预设的测量间隙持续子帧的数量可以为 6个子帧。 以 LTE系统为 例， 一个子帧包括 2个时隙 （slot ), 每个时隙持续 0.5ms (毫秒）， 一个子帧 持续 lms。
101d: 才艮据测量间隙的起点可以确定间隙偏移量。
根据测量间隙的起点与间隙偏移量（gapOffset )存在的对应关系， 确定 间隙偏移量。 其中， 测量间隙的起点与间隙偏移量 gapOffset满足如下对应关 系：
SFN mod T = FLOOR(gapOffset/10),
subframe = gapOffset mod 10,
其中， SFN为测量间隙的起点对应的系统帧号， subframe为测量间隙的 起点对应的子帧号， mod 表示取模运算， FLOOR 表示向下取整， T = MGRP/10。 MGRP ( Measurement Gap Repetition Period, 测量间隙重复周期） 表示间隙样式对应的测量间隙重复周期，例如，间隙样式 0和 1对应的 MGRP 分别为 40ms和 80ms。
另外， 具体实现时， 间隙偏移量具体可用 5bit (位）来指示， 5bit表示最 大范围 0到 31个子帧， 由于测量间隙的周期为 30个子帧， 因此， 检测偏移 量的范围可以包括 0到 29, 预留 30和 31。
下面举例说明如何确定间隙偏移量。 4叚设测量小区 I-PRS=10, n-PRS=l , 终端或定位中心确定 I-PRS=10对应的 PRS周期为 160个子帧， PRS偏移为 10个子帧， 则定位时隙的起点的系统帧号为 1 , 子帧号为 0, 并且已知定位时 隙的长度 n-PRS=l个子帧， 则定位时隙的位置如图 3中子帧号为 0的子帧所 示， 如果考虑测量间隙需要覆盖定位时隙及定位时隙前后各预留的一个子帧 的情况， 则测量间隙的覆盖范围共有 4种情况， 以子帧号表示测量间隙的覆 盖范围为 （6,7,8,9,0,1 )、 （7,8,9,0,1,2 )、 （8,9,0,1,2,3 )、 （9,0,1,2,3,4 ), 相应的测 量间隙的起点对应的系统帧号为 0, 子帧号分别为 6、 7、 8、 9, 测量间隙的 起点与间隙偏移量的对应关系， 则间隙偏移量取值可以为 6、 7、 8或 9。 当测 量小区的 PRS信息改变时， 如 I-PRS=20, 即 PRS周期为 160ms, PRS偏移为 20, 此时间隙偏移量可以为 16、 17、 18或 19, 则终端或定位中心应将更新后 的间隙偏移量通知基站， 使基站给终端配置正确的 gapOffset, 使终端在此测 量间隙内检测到 PRS, 提高 PRS的检测性能。
102: 终端或定位中心将间隙偏移量通知服务小区的基站。
优选的， 终端或定位中心将一个间隙偏移量通知基站。 另外， 终端或定 位中心还可以将多个间隙偏移量通知基站， 由基站从中选择一个。
服务小区的基站接收到终端或定位中心通知的间隙偏移量时， 服务小区 的基站确定终端将需要进行 RSTD异频测量。 或者， 在本实施例中， 也可以 通过一个通知用于指示终端需要进行 RSTD异频测量， 此时， 可以将间隙偏 移量和该通知同时发送给基站。 服务小区的基站接收到终端或定位中心通知 的间隙偏移量之后， 本实施例还包括：
103: 服务小区的基站将接收到的间隙偏移量发送给终端。
服务小区的基站可以向终端发送 RSTD异频测量的间隙配置信息， 该间 隙配置信息包括间隙样式和接收到的间隙偏移量； 在本实施例中， 基站也可以将间隙配置信息中的间隙样式配置成间隙样式 0。
服务小区的基站将接收到的间隙偏移量发送给终端， 因为终端根据服务 小区的基站下发的间隙配置信息进行 RSTD异频测量， 本实施例基站下发的 间隙配置信息中的间隙偏移量是参考终端上报的间隙偏移量确定的。
104: 终端接收间隙配置信息， 并根据间隙配置信息对测量小区的标识对 应的测量小区的 PRS进行 RSTD异频测量， 并根据测量小区的 RSTD异频测 量结果确定自身的位置。
其中， 本步骤是 OTDOA定位技术中惯用的技术手段， 这里仅简述其实 现过程： 终端根据间隙配置信息中的间隙偏移量计算得到测量间隙的起点， 从测量间隙的起点开始，在测量间隙持续子帧范围内，对所有测量小区的 PRS 进行 RSTD异频测量， 并根据各个测量小区的 RSTD异频测量结果确定自身 的位置。其中， "根据间隙配置信息中的间隙偏移量计算得到测量间隙的起点" 可以采用步骤 101d中表示测量间隙的起点与间隙偏移量 gapOffset对应关系 的公式获得。
本实施例通过根据测量小区的 PRS信息确定间隙偏移量， 并将间隙偏移 量通知服务小区的基站， 这种根据测量小区的 PRS信息确定间隙偏移量的方 案，提高了终端在测量间隙内检测到测量小区的 PRS的概率，从而提高了 PRS 的检测性能。 同时， 在根据测量小区的 PRS信息确定间隙偏移量时， 保证测 量间隙能够覆盖定位时隙， 从而确保终端在测量间隙内能够检测到测量小区 的 PRS, 大大地提高了 PRS的检测性能。 参见图 4,本实施例提供了另一种测量间隙的配置方法，该方法通过 OAM
( Operation Administration Maintenance, 操作管理维护）系统对基站的间隙偏 移量进行配置， 包括：
201 : OAM 系统对服务小区的基站的间隙配置信息中的间隙偏移量进行 配置；
进一步的， OAM系统根据测量小区的频率， 对基站的间隙配置信息中的 间隙偏移量进行配置， 测量小区的频率不同， 则配置的间隙偏移量不同。 另 实施例中， OAM系统可以将间隙配置信息中的间隙样式配置成间隙样式 0。 可选的， 步骤 201之前， 本实施例还包括：
200a: 定位中心将 RSTD异频测量的定位辅助数据发送给终端； 其中， RSTD异频测量的定位辅助数据包括测量小区的标识和测量小区的
PRS 信息等。 当测量小区与服务小区的频率不同时， 定位辅助数据还包括测 量小区的频率。 PRS信息包括 I-PRS和 n-PRS, 例如， n-PRS的值可为 1、 2、
4、 6。
200b: OAM系统才艮据测量小区的 PRS信息， 确定间隙偏移量； 根据测量小区的 PRS 信息确定间隔偏移量的过程可以参考步骤 101a-101d, 这里不再贅述。 进一步的， 测量小区的频率不同， 则间隙偏移量 不同。
可选的， 步骤 201之后， 本实施例还包括：
202: 服务小区的基站将间隙配置信息发送给终端。
当测量小区的频率不同时， 基站接收终端发送的获取间隙配置信息请求， 请求中携带测量小区的频率， 基站将请求的测量小区的频率对应的间隙配置 信息发送给终端。
203: 终端接收并根据间隙配置信息， 对测量小区的标识相应测量小区的 PRS进行 RSTD异频测量， 并根据各个测量小区的 RSTD异频测量结果确定 自身的位置。
本步骤可以参考步骤 104, 这里不再贅述。
本实施例中通过根据测量小区的 PRS信息确定间隙偏移量， 提高了终端 在测量间隙内检测到测量小区的 PRS的概率， 从而提高了 PRS的检测性能。 同时， 在根据测量小区的 PRS信息确定间隙偏移量时， 保证测量间隙能够覆 盖定位时隙， 从而确保终端在测量间隙内能够检测到测量小区的 PRS , 大大 地提高了 PRS的检测性能。 另外， 基站使用 OAM系统配置的间隙偏移量， 不需要额外的信令通知， 降低了信令开销和定位时延； 同时， 相对于基站使用预先约定的间隙偏移量， 本实施例能够通过 OAM灵活配置间隙偏移量。 参见图 5 , 本实施例提供了另一种测量间隙的配置方法， 该配置方法由终 端或定位中心执行， 包括：
S31 : 根据参与定位的小区的 PRS信息或参与定位的小区的频率信息，确 定用于获取间隙偏移量的信息；
S32: 将用于获取间隙偏移量的信息通知服务小区的基站， 使基站根据用 于获取间隙偏移量的信息确定间隙偏移量。
本实施例通过根据参与定位的小区的 PRS信息， 确定用于获取间隙偏移 量的信息， 将用于获取间隙偏移量的信息通知服务小区的基站， 使基站根据 用于获取间隙偏移量的信息确定间隙偏移量，这种才艮据参与定位的小区的 PRS 配置间隙偏移量的方案， 提高了终端在测量间隙内检测到参与定位的小区的 PRS的概率， 从而提高了 PRS的检测性能。 另外， 相对于将间隙偏移量通知 服务小区的基站的配置方法， 降低了对终端计算能力的要求。 参见图 6, 本实施例提供了另一种测量间隙的配置方法， 该方法根据参与 定位的小区的 PRS信息， 确定用于获取间隙偏移量的信息， 包括：
300: 定位中心将异频测量的定位辅助数据发送给终端；

或者， 该用于获取间隙偏移量的信息包括参与定位的异频小区的 PRS信 息；
其中， PRS信息包括 I-PRS (定位参考信号索引 )和 n-PRS (定位时隙的 长度）， n-PRS的值可为 1、 2、 4、 6。

步骤 301b中确定定位时隙的起点与步骤 101b的具体实现过程相同， 这 里不再贅述。
302: 终端或定位中心将用于获取间隙偏移量的信息发送给服务小区的基 站；
服务小区的基站接收到终端或定位中心发送的用于获取间隙偏移量的信 息时， 服务小区的基站确定终端将需要进行 RSTD异频测量。 或者， 在本实 施例中， 也可以通过一个通知用于指示终端需要进行 RSTD异频测量， 此时， 可以将间隙偏移量和该通知同时发送给基站。 服务小区的基站接收到终端或 定位中心发送的用于获取间隙偏移量的信息之后， 本实施例还包括：
303:服务小区的基站根据用于获取间隙偏移量的信息，确定间隙偏移量； 1 ) 当该用于获取间隙偏移量的信息包括参与定位的全部小区的 PRS 信 息， 或包括参与定位的异频小区的 PRS信息时， 首先根据参与定位的异频小 区的 PRS信息， 采用步骤 301a和 301b的方法确定定位时隙的起点和长度， 然后再采用步骤 303a和 303b的方法确定间隙偏移量。
2 ) 当该用于获取间隙偏移量的信息包括定位时隙的起点和长度时， 本步 骤具体包括：
303a: 根据定位时隙的起点、 定位时隙的长度 n-PRS、 以及预设的测量间 隙持续子帧的数量， 确定测量间隙的起点；

305: 终端接收并根据间隙配置信息， 对测量小区的标识相应测量小区的 PRS进行 RSTD异频测量， 并根据各个测量小区的 RSTD异频测量结果确定 自身的位置。
其中， 本步骤是 OTDOA定位技术中惯用的技术手段， 这里仅简述其实 现过程： 终端根据间隙配置信息中的间隙偏移量计算得到测量间隙的起点， 从测量间隙的起点开始， 在测量间隙持续子帧范围内， 对所有测量小区的定 位参考信号进行异频测量， 并根据各个小区的异频测量结果确定自身的位置。 其中， "根据间隙配置信息中的间隙偏移量计算得到测量间隙的起点" 具体可 以采用步骤 101d中的表示测量间隙的起点与间隙偏移量 gapOffset对应关系 的公式进行计算。
本实施例通过根据参与定位的小区的 PRS信息， 确定用于获取间隙偏移 量的信息， 将用于获取间隙偏移量的信息通知服务小区的基站， 使基站根据 用于获取间隙偏移量的信息计算间隙偏移量，这种根据参与定位的小区的 PRS 配置间隙偏移量的方案， 提高了终端在测量间隙内检测到参与定位的小区的
PRS的概率， 从而提高了 PRS的检测性能。 同时， 在根据用于获取间隙偏移 量的信息计算间隙偏移量时， 保证测量间隙能够覆盖定位时隙， 从而确保终 端在测量间隙内能够检测到参与定位的小区的 PRS, 大大地提高了 PRS的检 测性能。 参见图 7, 本实施例提供了另一种测量间隙的配置方法， 该方法根据参与 定位的小区的频率信息， 确定用于获取间隙偏移量的信息， 包括：
