Description

载波测量方法及装置 本申请要求于 2012 年 6 月 5 日提交中国专利局、 申请号为 CN 20121 0183261. 2 , 发明名称为 "载波测量方法及装置" 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
本发明涉及通信领域， 尤其涉及一种载波测量方法及装置。 背景技术
随着移动通信系统的快速发展， 为了保持 3GPP ( the 3rd generation partnership project, 第三代合作伙伴计划） 的竟争优势， LTE-A (long term evolution -advanced, 长期演进项目的后续演进)的标准制定工作正在进行。 为了进一步的提高通信系统的频谱效率和用户吞吐量， 在 LTE-A 的 Release- 10版本里引入了 CA ( carrier gggregation, 载波聚合）技术， 该技 术能够使得 UE ( user equipment, 用户设备）同时使用多个普通载波进行上 下行通信， 从而支持高速数据传输。 在 UE使用的多个普通载波中， 可以选 择一个载波作为主载波（例如：选择所述 UE所使用的第一个载波为主载波， 但不限于此）， 其余载波作为辅载波。
在 Release-11 版本里， 3GPP提出了一种新的载波类型一 NCT ( new carrier yype, 新类型载波）。 NCT被考虑作为一种非后向兼容的载波， 可以 通过修改现有的机制以增强载波性能， 例如： 增强频谱效率、 提高异构网 络支持、 节能等。 为了实现上述性能的提升， 大部分公司倾向于在时频域 或子帧上去除或缩减 CRS ( cell reference signaling, 小区参考信号）， 保留 CSI-RS ( channel-state information reference signal ,信道状态信息参考信号 )。
在通信过程中， 基站需要对各载波进行测量， 确定小区的信号强度信 息， 进而决定是否为 UE增加小区作为服务小区等相关操作。 随着 3GPP的 发展，在高版本的 3GPP协议中逐渐会提出其他类型的载波， 以推动通信技 术的发展。

在本发明各实施例中， 指定载波可以理解为基站确定且需要测试的不 同载波， 如普通载波、 成员载波、 新类型载波、 等。
实施例一
本发明实施例提供了一种载波测量方法， 如图 1所示， 包括：

102、 所述基站向用户终端下发测量任务， 以指示所述用户终端对指定 载波进行测量， 所述测量任务包括所述指定载波的参考信号或所述指定载 波的载波类型。
值得说明的是， 本发明实施例提供的方法可以由基站通过 RRC ( radio resource control, 无线资源控制） 消息向用户终端下发测量任务， 但不仅限 于此。 其中，用户终端需要测量的参考信号包括 CRS ( cell reference signaling, 小区参考信号 )或 CSI-RS ( channel-state information reference signal , 信道 状态信息参考信号）等。

103、 所述基站接收所述用户终端上报的测量报告， 所述测量报告中包 括所述用户终端根据所述测量任务测量所述指定载波得到的测量结果。
基站在获取测量报告后， 能够根据测量结果确定指定载波的信号质量 和信号强度， 从而便于基站对用户终端和该指定载波进行管理， 例如： 基 站决定是否为该用户终端增加新的载波， 或者对该指定载波进行维护， 或 者是决定小区间切换的场景等。
值得说明的是， 所述新类型载波也可以称为扩展载波 （extensional carrier )或 I1付力口载波 (additional carrier)。
本发明实施例提供的载波测量方法， 能够有效实现对普通载波和新类 型载波的载波测量， 从而便于基站根据载波的测量结果对载波或当前用户 终端进行管理操作， 确保通信质量。 实施例二
本发明实施例提供了一种载波测量方法， 进一步将用户终端作为执行 主体对实施例一进行描述， 如图 2所示， 包括：
201、 用户终端接收基站下发的测量任务， 所述测量任务用于指示所述 用户终端对指定载波进行测量， 所述测量任务包括所述指定载波的参考信 号或所述指定载波的载波类型， 所述指定载波至少包括新类型载波或普通 载波。

具体的， 当指定载波为新类型载波时， 所述用户终端确定需要测量的 参考信号为指定载波的 CSI-RS; 当指定载波为普通载波时， 所述用户终端 确定需要测量的参考信号为指定载波的 CRS。
本发明实施例提供的载波测量方法， 能够根据基站下发的测量任务实 现对普通载波和新类型载波的测量， 将测量结果上报给基站， 以便于基站 根据载波的测量结果对载波或当前用户终端进行管理操作。 实施例三
本发明实施例提供了一种载波测量方法， 进一步对实施例一、 二进行 描述， 如图 3所示， 包括：
301、 基站接收相邻基站发送的所述相邻基站的指定载波的载波类型。 需要强调的是， 本发明实施例中的相邻基站至少包括通过 X2接口或 S1接口与所述基站相连的基站。 具体的， 在基站间的接口建立时， 所述基 站通过接收相邻基站发送的所述相邻基站的指定载波的载波类型， 与相邻 基站交互各自基站下小区的小区信息， 包括： 小区的载波频段、 小区 ID ( identity, 标识）等信息。 值得说明的是， 在本实施例中， 当前基站与相 邻基站交互的小区信息还包括各自基站下小区的载波类型， 所述载波类型 包括普通载波和新类型载波。
例如，基站 1和基站 2通过 X2接口建立连接为例进行举例说明： 基站 2在向基站 1发送的 X2 setup request ( X2接口建立请求） 消息中携带基站 2下小区及相邻小区的小区信息，基站 1在向基站 2发送的 X2 setup response ( X2接口建立响应） 消息中携带基站 1下小区及相邻小区的小区信息。
另一方面，当基站 1和基站 2通过 S1接口建立连接时，可以通过 MME ( mobility management entity , 移动管理实体）进行信令交互， 以使得基站 1和基站 2获取各自基站以及相邻基站下各小区的小区信息。
值得说明的是， 所述指定载波的载波类型至少包括新类型载波或普通 载波。 其中， 新类型载波是 3GPP在 LTE-A的 Release-11版本中提出的一 种新的载波类型， 这种类型的载波去除了 CRS。 根据目前标准， 新类型载 波不能独自配置给 UE ( user equipment, 用户终端 )作为服务载波， 需要基 站配置一个普通载波作为该新类型载波的关联载波。 所以当所述基站下存 在新类型载波时， 还需要向相邻基站指示与该新类型载波相关联的普通载 波， 该普通载波能够独自配置给 UE作为服务小区。
可选的， 基站可以根据新类型载波和普通载波的频段， 选择与新类型 载波所处频段较为接近的普通载波作为该新类型载波的关联载波， 也可以 按照其他要求为新类型载波配置关联载波， 此处不做限定。
302、 基站确定所述基站或所述基站的相邻基站具有指定载波， 所述指 定载波至少包括新类型载波或普通载波。
值得说明的是， 本发明实施例中的所述普通载波为传统的后向兼容载 波， 所述新类型载波为增强型的非后向兼容载波， 包括在 Release-11 版本 里， 3GPP提出的一种新的载波类型一 NCT。 NCT被考虑作为一种非后向兼 容的载波， 可以通过修改现有的机制以增强载波性能， 例如： 增强频谱效 率、 提高异构网络支持、 节能等。 为了实现上述性能的提升， 大部分公司 倾向于在时频域或子帧上去除或缩减 CRS, 保留 CSI-RS。 需要强调的是， 所述新类型载波也可以称为扩展载波或附加载波。
303、 当所述基站需要对指定载波进行测量时， 根据该指定载波的载波 类型生成测量任务， 所述测量任务包括所述指定载波的参考信号或所述指 定载波的载波类型。
值得说明的是， UE在对普通载波进行测量时是基于 CRS实现的， UE 通过测量普通载波的 CRS以获得该普通载波的测量结果。 由于在新类型载 波中去除了 CRS,所以本实施例通过测量新类型载波的 CSI-RS以对新类型 载波进行测量。 其中， 与 CRS相比， CSI-RS的频率较低， 但是也能够用于 测量新类型载波的信号质量。
具体的， 当所述指定载波为新类型载波时，需要 UE测量的所述新类型 载波的参考信号为 CSI-RS; 当所述指定载波为普通载波时， 需要 UE测量 的所述普通载波的参考信号为 CRS。
需要说明的是， 每个测量任务包括测量实体信息（ measurement object ) 和报告配置信息（report configuration ), 测量实体信息所述报告配置信息用 于指示需要 UE进行测量的指定载波，报告配置信息用于确定触发 UE向基 站发送测量报告的配置信息。 其中， 测量实体信息和报告配置信息是测量 任务中的信元消息， 基站可以优选的将参考信号指示信息携带于测量实体 信息中， 也可以携带于报告配置信息中， 此处不做限定。
304、 所述基站向 UE下发测量任务， 以指示所述 UE对所述指定载波 进行测量， 所述测量任务包括所述指定载波的参考信号或所述指定载波的 载波类型。
305、 UE接收所述测量任务， 根据所述测量任务确定需要测量的参考 信号。
具体的， 当指定载波是新类型载波时， UE确定需要测量的参考信号为 所述指定载波的 CSI-RS; 或者， 当指定载波是普通载波时， UE确定需要 测量的参考信号为所述指定载波的 CRS。
可选的，除了上述 UE根据测量任务直接确定需要测量的参考信号的方 法， UE还可以通过测量任务确定所述指定载波的载波类型， 进而根据确定 的载波类型确定需要测量的参考信号， 具体如下：
当所述指定载波的载波类型为所述新类型载波或所述普通载波时， 所 述 UE 根据所述指定载波的载波类型确定需要测量的参考信号为所述 CSI-RS或所述 CRS。
值得说明的是，釆用 UE根据测量任务直接确定需要测量的参考信号的 方法， 能够降低 UE的复杂度， 减少测量报告的触发延迟
306、 UE对所述需要测量的参考信号进行测量， 得到测量结果， 所述 测量结果包括 CSI-RS测量结果或 CRS测量结果。
307、 当 UE得到的测量结果满足测量任务中的报告配置信息而触发上 报测量报告时， 向基站发送测量报告， 所述测量报告中包括 UE对需要测量 的参考信号完成测量后得到的测量结果。
308、 基站接收 UE上报的测量报告， 获取指定载波的测量结果。
基站在获取指定载波的测量结果后， 能够根据测量结果确定指定载波 的信号质量和信号强度， 进而对 UE和该指定载波进行管理， 例如： 决定是 否为 UE增加新的载波，或者对该指定载波进行维护，或者是决定小区间切 换的场景等。
本发明实施例提供的载波测量方法， 能够实现对普通载波和新类型载 波的测量， 从而便于基站根据载波测量结果载波或当前用户终端进行管理 操作； 同时本实施例中的基站能够确定需要 UE测量的参考信号， 能够降低 UE的复杂度， 减少测量报告的触发延迟。 实施例四
本发明实施例提供了一种载波测量方法，自 UE侧对上述实施例进行了 描述， 如图 4所示， 所述方法包括：
401、 UE接收基站发送的测量任务。
其中， 所述测量任务用于指示所述 UE确定待测量载波。
402、 所述 UE根据所述测量任务确定待测量的载波包括新类型载波和 普通载波。
其中， 所述普通载波为传统的后向兼容载波， 所述新类型载波为增强 型的非后向兼容载波， 所述新类型载波是 3GPP在 LTE-A的 Release-11版 本中提出的一种新的载波类型， 被考虑作为一种非后向兼容的载波， 可以 通过修改现有的机制以增强载波性能， 例如： 增强频谱效率、 提高异构网 络支持、 节能等。 为了实现上述性能的提升， 大部分公司倾向于在时频域 或子帧上去除或缩减 CRS, 保留 CSI-RS。 403、所述 UE测量所述普通载波的 CRS和所述新类型载波的 CSI-RS, 并获取 CRS测量结果和 CSI-RS测量结果。
404、 当所述 CSI-RS 的信号质量优于所述 CRS 的信号质量时， 所述 UE将所述 CSI-RS测量结果发送至所述基站； 当所述 CRS的信号质量优于 所述 CSI-RS的信号质量时，所述 UE将所述 CRS测量结果发送至所述基站。
值得说明的是， 由于新类型载波去除了 CRS, 所以当需要测量的指定 载波为新类型载波时， UE得到的 CSI-RS测量结果较好， CRS测量结果较 差。
本发明实施例提供的载波测量方法， 当接收到基站下发的测量任务时， 根据测量任务确定需要测量的指定载波， 进而对该载波的 CRS和 CSI-RS 分别进行测量， 选择信号质量较好的参考信号并将该参考信号的测量结果 上报给基站， 以便于基站对所述指定载波进行管理操作。 实施例五
本发明实施例提供了一种载波测量方法， 为对实施例四的详述， 如图 5 所示， 包括：
501、 UE接收基站发送的测量任务， 所述测量任务用于指示所述 UE 确定待测量载波。
502、 所述 UE根据所述测量任务确定待测量的载波包括新类型载波和 普通载波。
其中， 所述普通载波为传统的后向兼容载波， 所述新类型载波为增强 型的非后向兼容载波， 所述新类型载波是 3GPP在 LTE-A的 Release-11版 本中提出的一种新的载波类型， 被考虑作为一种非后向兼容的载波， 可以 通过修改现有的机制以增强载波性能， 例如： 增强频谱效率、 提高异构网 络支持、 节能等。 为了实现上述性能的提升， 大部分公司倾向于在时频域 或子帧上去除或缩减 CRS, 保留 CSI-RS。
值得说明的是， 本实施例中的 UE支持 LTE-A的 Release-11版本， 即 UE能够以新类型载波作为服务小区进行通信。
503、所述 UE测量所述普通载波的 CRS和所述新类型载波的 CSI-RS, 并获取 CRS测量结果和 CSI-RS测量结果。
504、 所述 UE将所述 CRS测量结果和 CSI-RS测量结果进行比对， 选 择信号质量较优的测量结果作为所述待测量载波的测量结果， 根据该测量 结果确定所述待测量载波的参考信号或所述待测量载波的载波类型， 生成 测量报告， 将所述测量报告发送至所述基站。
其中， 所述测量报告至少包括所述待测量载波的测量结果、 以及所述 待测量载波的参考信号或所述待测量载波的载波类型， 以供所述基站确定 所述待测量载波的载波类型。
