Definitions

  • the embodiments of the present invention relate to the field of communications, and in particular, to a measurement configuration and reporting method and device for a multi-carrier system. Background technique
  • LTE Long Term Evolution
  • the source base station provides only the information of one cell of the target base station for the admission decision of the target base station when making the handover decision.
  • LTE-A Long Term Evolution Advanced, evolved LTE
  • the peak rate of the system is significantly higher than that of LTE, requiring downlink lGbps and uplink up to 500 Mbps. If only one carrier with a maximum bandwidth of 20MHz is used, the peak rate requirement cannot be reached. Therefore, the LTE-A system needs to expand the bandwidth that the terminal can use, thereby introducing a CA (Carrier Aggregation) technology, that is, multiple consecutive or discontinuous carriers under the same eNB (evolved Node-B, base station). They are aggregated and serve the UE (User Equipment) to provide the required rate. These aggregated carriers are also called CC (Component Carrier).
  • CA Carrier Aggregation
  • Each cell can be a member carrier, and cells (member carriers) under different eNBs cannot be aggregated. In order to ensure that UEs of LTE can work under each aggregated carrier, each carrier does not exceed 20 MHz at most.
  • the CA technology of LTE-A is shown in Figure 2.
  • the LTE-A base station shown in Figure 2 has four carriers that can be aggregated. The base station can perform data transmission with the UE on four carriers at the same time to improve system throughput. .
  • the handover of the LTE system can be divided into two categories from the perspective of the number of participating nodes, namely intra-eNB handover and inter-eNB handover.
  • the intra-eNB handover may be a handover required to update the key parameters for security reasons.
  • For inter-eNB handover considering the interface type between the source and target base stations, it can be divided into X2 handover and S1 handover, and the messages are transmitted by using the X2 and S1 interfaces respectively, so the message of the S1 handover passes through the MME node. Since the UE in the LTE system operates on a single carrier, the handover is also a handover between single carrier cells.
  • the UE can simultaneously aggregate signaling scheduling and traffic transmission on multiple carriers.
  • each component carrier that is aggregated is a cell.
  • the Pcdl has the following characteristics: only the PUCCH (Physical Uplink Control Channel) on the Pcdl; when the Pcdl fails to generate a radio link, the UE triggers the RRC (Radio Resource Control) connection reestablishment process; Pcdl
  • the system information acquisition and update is the same as the LTE process; the NAS information is obtained through Pcdl; the random access is only performed on the Pcell.
  • the UE has only one Pcell, but can have one or more Scdls.
  • the frequency/carrier where Pcdl is located is called PCC (Primary Member Carrier), and the frequency/carrier where Scell is located is called SCC (Secondary Member Carrier). Since the carrier aggregation feature is introduced in the LTE-A system, the UE can simultaneously aggregate signaling scheduling and service transmission on multiple carriers. Therefore, the source base station needs to provide more information to the target base station in the multi-carrier handover process.
  • the UE can only provide measurement results of one or more cells on one frequency point each time the UE performs the measurement report.
  • the source eNB wants to trigger multi-carrier handover, it needs to wait for multiple measurement reporting results, which will increase the total measurement reporting delay, causing the handover decision to be delayed or the UE to lose connectivity, causing dropped calls; If the source eNB does not wait for multiple measurement result reports and directly decides to switch, then the target eNB cannot be provided with a suitable candidate cell list, which may cause the target eNB to blindly select the target cell without understanding the channel quality, and increase the handover failure.

多载波系统的测量配置和上报方法及设备
本申请要求于 2010年 6 月 18 日提交中国专利局， 申请号为 201010209864.6, 发明名称为 "多载波系统的测量配置和上报方法及 设备"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
本发明实施例涉及通信领域，尤其涉及一种多载波系统的测量配 置和上报方法及设备。 背景技术
LTE ( Long Term Evolution, 长期演进）及以前的无线通信系统 中， 一个小区中只有一个载波， 在 LTE系统中最大带宽为 20MHz, 如图 1所示。 由于 LTE系统是单载波系统， 源基站在做切换判决时 只提供给目标基站一个小区的信息供目标侧基站做接纳判决。
在 LTE-A ( LTE Advanced, 演进的 LTE )系统中， 系统的峰值速 率比 LTE有巨大的提高， 要求达到下行 lGbps, 上行达到 500Mbps。 如果只使用一个最大带宽为 20MHz的载波是无法达到峰值速率要求 的。 因此， LTE-A 系统需要扩展终端可以使用的带宽， 由此引入了 CA ( Carrier Aggregation, 载波聚合 )技术， 即将同一个 eNB ( evolved Node-B , 基站） 下的多个连续或不连续的载波聚合在一起， 同时为 UE ( User Equipment, 用户终端）服务， 以提供所需的速率， 这些聚 合在一起的载波又称为 CC ( Component Carrier, 成员载波）。 每个小 区都可以是一个成员载波， 不同 eNB下的小区 （成员载波） 不能聚 合。 为了保证 LTE的 UE能在每一个聚合的载波下工作，每一个载波 最大不超过 20MHz。 LTE-A的 CA技术如图 2示例， 其中图 2所示 的 LTE-A的基站下有 4个可以聚合的载波， 基站可以同时在 4个载 波上和 UE进行数据传输， 以提高系统吞吐量。
LTE 系统的切换从参与节点个数的角度可以分为两类， 即 intra-eNB切换和 inter-eNB切换。 其中 intra-eNB切换可以是出于安 全考虑需要更新密钥参数所做的切换。 对于 inter-eNB切换， 考虑到 源和目标基站之间的接口类型， 又可分为 X2切换和 S1切换， 分别 利用 X2和 S1接口传递消息，所以 S1切换的消息会经过 MME节点。 LTE系统中的 UE由于工作在单个载波上， 因此切换也是单载波小区 之间的切换。
在 LTE-A系统中， UE可同时聚合在多个载波上进行信令调度和 业务传输。 当 UE使用 CA时， 聚合的每个成员载波都是一个小区， 为了对这些小区进行区分， 引入了主服务小区（ Pcdl )和辅服务小区 ( Scell )的概念。 Pcdl有以下特性：仅在 Pcdl上有 PUCCH ( Physical Uplink Control Channel, 物理上行控制信道）； 当 Pcdl发生无线链路 失败时， UE触发 RRC ( Radio Resource Control, 无线资源控制协议） 连接重建过程； Pcdl的系统信息获取和更新与 LTE过程一样； NAS 信息通过 Pcdl获得；随机接入仅在 Pcell上进行。 UE仅有一个 Pcell, 但可以有一个或多个 Scdl。 Pcdl所在的频率 /载波称为 PCC (主成员 载波）， Scell所在的频率 /载波称为 SCC (辅成员载波）。 由于 LTE-A 系统中引入了载波聚合特性， UE可同时聚合在多个载波上进行信令 调度和业务传输，因此在多载波切换过程中源基站需要给目标基站提 供更多的信息。
现有技术中， UE每次测量上报， 仅能提供一个频点上的一个或 多个小区的测量结果。 而对于 CA状态下的 UE, 源 eNB如果想触发 多载波切换， 那么需要等待多次测量上报结果， 这会增大总的测量上 报时延，导致切换判决推迟或者 UE失去连接，造成掉话；如果源 eNB 不等待多次测量结果上报， 直接判决切换， 那么就无法向目标 eNB 提供合适的候选小区列表， 会导致目标 eNB在不了解信道质量的情 况下盲目选择目标小区， 增大切换失败的概率。 发明内容 本发明实施例提供了一种多载波系统的测量配置和上报方法及 设备， 实现在多载波系统中通过测量上报消息携带多载波测量结果。

具体实施方式
为了清楚地介绍本发明实施例提供的多载波系统的测量配置和 上报方法， 下面首先介绍 LTE系统中的测量机制、 以及 LTE-A系统 中的切换机制。
LTE系统中， 基站通过 RRC ( Radio Resource Control, 无线资源 控制协议）信令（RRC重配消息） 向 UE发送测量配置信息， UE根 据测量配置信息的内容进行测量（同频、 异频、 异技术）， 然后将测 量结果上报给网络。
其中， 基站发送的测量配置信息的组织结构如下：
测量对象： 以频点为基本单位， 每个被配置的测量对象为一个单 独频点， 拥有单独的测量对象标识（ID ), 下面可以包括载波频率， 邻小区黑白名单， 需要上报 CGI (全球小区标识） 的小区等内容。
上报配置： 按照触发类型分为事件触发上报和周期触发上报， 每 个上报配置拥有单独的 ID。 事件触发类型的上报配置会配给某一个 事件的门限值和满足触发条件的持续时间 （Time to Trigger ), 周期性 触发类型的上报配置会配给周期性触发的目的 （例如， 上报 CGI )。 另外还包含触发测量量， 上报测量量， 上报间隔、 次数等信息。
测量标识： 单独的 ID, 可以同时连接一个测量对象与上 配置。 如果达到了开启测量的门限， UE会根据测量标识的有无判断是否进 行该种测量。
其他参数： 还可能包括测量量配置， 测量开启门限以及速度状态 参数等其他参数。
UE根据测量配置信息向基站发送测量上报有三种触发方式： 事 件触发上报、 周期上报、 事件触发周期上报。 这三种方式根据上报配 置中各种参数的组合进行区分。 例如， 当上报配置中的触发类型为事 件触发，并且配给了某个事件的门限值和满足触发条件的持续时间等 相关参数， 没有配置测量间隔或上报次数等参数时， UE将按照一次 事件触发方式进行上报。
UE发送的测量上报消息的主要内容包括：
每条测量上报消息仅能上报一个测量标识所对应的内容，即一个 频点下满足相关上报配置的小区， 测量上报消息包含内容有： 测量标 识、 本小区各测量量（RSRP和 RSRQ )、 满足条件的邻小区的物理层 小区 ID、 是否上报各邻小区测量量与 CGI取决于网络是否配置 UE 上报这些信息； 其中， RSRP是 Reference Signal Received Power (参 考信号接收功率）， RSRQ是 Reference Signal Received Quality (参考 信号接收质量）， 二者都是测量量。
测量上报的流程包括：
在每一个测量标识下， 分为测量评估与组织上报两个过程： a )测量评估： UE通过测量， 寻找到某个测量对象中满足上报配 置的小区， 进行评估， 当小区在一定时间内 （TimeToTrigger )都满足 准入条件， 将被包含在上报列表中； 一旦有新的小区进入上报列表， 就会触发上报过程。
b )组织上报： 即填写测量上报消息的过程， 需要填写测量标识， 本小区测量信息， 邻小区测量信息。 邻小区测量信息的获得过程是， 将 a ) 中的上报列表里包含的小区按照配置中给定的上报测量量进行 质量排序， 按从高到底的顺序填入测量上报消息。
上报列表中包含的邻小区的个数是由以下几个条件决定的： a )上报列表的准入条件： 当某个小区的测量量达到了准入准则 (例如， 该小区的信号质量大于某个门限值）；
b )上报列表的离开条件： 当某个小区的测量量达到了离开准则 (例如， 该小区的信号质量小于某个门限值 )；
C ) 小区被包含在上报列表的条件： 当某个小区在一定时间内
( TimeToTrigger )都满足上报列表的准入条件， 则将被包含在上报列 表中。
d ) 小区从上报列表中被删除的条件： 当某个小区在一定时间内 ( TimeToTrigger )都满足上报列表的萬开条件， 则将从上报列表中被 删除。
当 UE进行上报的时候， 会将仍然留在上报列表中的所有邻小区 都上报给网络，并不考虑该小区是否已经在之前的上报过程中被上报 了。
下面介绍 LTE-A多载波相关概念：
当 UE使用 CA时， 聚合的每个成员载波都是一个小区， 为了对 这些小区进行区分， 引入了主服务小区（Pcdl )和辅服务小区（Scell ) 的概念。 Pcdl有以下特性：
1 )仅在 Pcell上有 PUCCH;
2 ) 当 Pcdl发生无线链路失败时， UE触发 RRC连接重建过程；
3 ) Pcell的系统信息获取和更新与 LTE过程一样；
4 ) NAS信息通过 Pcdl获得；
5 ) 随机接入仅在 Pcell上进行。
UE仅有一个 Pcell, 可以有一个或多个 Scdl。 Pcdl所在的频率 / 载波称为 PCC (主成员载波）， Scell所在的频率 /载波称为 SCC (辅 成员载波）。
为了更好的支持工作在 CA下的 UE的移动性管理， LTE-A引入 了针对 Pcell的 A3-Pcdl、 A5-Pcell和 B2-Pcdl事件， 这三者相对于 LTE的 A3、 A5和 B2事件的区别是： 作为测量比较参考的服务小区 是 Pcdl。
为了更好的支持工作在 CA下的 UE的载波 /小区管理， LTE-A引 入了针对 Scell的同频 A3-Scdl事件， 该事件相对于 LTE的 A3事件 的区别是： 作为测量比较参考的服务小区是 Scdl, 且仅能进行同频 的测量结果比较。 另外， Scdl上也可以配置 A1和 A2事件。 由于目 前 LTE-A事件的命名还没有确定， Scdl上配置的 Al、 A2和同频 A3-Scell事件也可以称为 Cl、 C2和 C3事件， 以便与 Pcell上配置的 Al、 A2和 A3-Pcell进行区分。
由于 LTE-A允许多载波切换， 因此 LTE-A切换流程与 LTE切换 流程不同， 包括：
1 )源 eNB在切换准备阶段， 选择一个目标 Pcell, 并将其放入接 口的切换请求消息中，通知目标 eNB, 另外该消息也可以携带包含多 个 Scdl的候选小区列表；
2 )目标 eNB收到源 eNB发送的切换请求消息后， 可以重新选择 Pcell, 同时， 目标 eNB可以根据候选 Scdl列表， 选择切换后的目标 Scell;
3 ) 目标 eNB将其选择的目标 Pcell和 Scell放入切换命令， 通过 源 eNB透传给 UE;
4 ) UE收到切换命令后， 按照其中的 Pcell和 Scell信息， 进行多 载波切换。
下面将结合本发明的实施例中的附图，对本发明的实施例中的技 术方案进行清楚、 完整地描述， 显然， 下面所描述的实施例仅仅是本 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， 都属于本发明的实施例保护的范围。

本发明实施例二提供一种多载波系统的测量配置和上报方法，该 方法应用的场景如图 4所示， 其中， UE当前工作在基站 1下， 聚合 了小区 1、 小区 2和小区 3, 其中小区 1所在的频率 fl为 PCC, 小区 1为 Pcdl, 小区 2和小区 3所在的频率 f2和 f3均为 SCC, 这两个小 区均为 Scdl。 小区 5为 fl上的邻小区， 小区 6为 f2上的邻小区， 小 区 7为 f3上的邻小区， 小区 4和小区 8为 f4上的邻小区。
本发明实施例中， 基站 1 为了进行移动性管理和 /或载波管理， 使用 RRC连接重配消息对终端进行测量配置。 为了达到附加测量结 果上报的目的，基站 1在配置 Pcdl相关的测量时，例如 A3-Pcdl( A3 ), 同时配置当 A3-Pcdl ( A3 )上报时需要携带附加的测量结果（可以不 包括触发此次上报的频点上的小区）， 这些测量结果包括以下一种或 多种：
其他测量频点上的最强小区或者信道质量较强的前几个小区（即 按照信道质量由强到弱的配置个数的小区）；
其他测量频点上仍在上报列表中的最强小区或者信道质量较强 的前几个小区 （即按照信道质量由强到弱的配置个数的）； 当前处于其他测量标识对应的上报列表中的小区； 配置的测量事件、 或测量对象、 或测量标识、 或服务小区、 或测 量白名单小区对应的测量结果；

满足一定条件的小区 （如满足进入条件， 但是 TimeToTrigger未 满足； 信号质量大于某个预先设定的门限）； 例如事件 A3-Scell ( C3 ) 对应的测量目标小区， 或者信道质量大于某个门限的小区， 并且可以 配置让 UE上报这些小区的信道质量， 这些测量配置本身可以通过测 量 id、 测量事件或者测量对象来标识；
可以与触发上 的小区进行载波聚合的小区。
所述多载波测量结果包括以下选项的一种或多种：
附加测量结果对应的测量标识；
附加测量结果中测量上报小区的标识；
附加测量结果中测量上报小区的信道质量。
进一步的， 基站也可以在测量配置中限定允许上报的最大小区 数、 允许上报小区需要满足的最低门限、 或允许上报的最大频点数、 每个频点允许上报的最大小区数等， 以达到降低信令开销的目的。
需要说明的是， 上述以基站 1在配置 Pcdl相关的测量时进行的 说明同样适用于基站 1在配置 Scell相关的测量时所需要的技术手段， 此时测量结果中所包括的满足一定条件的小区可以是其他事件 A3-Scell ( C3 )对应的测量目标小区。
具体的，下面以基站 1对终端进行多载波系统的测量配置为例进 行说明， 基站 1为了进行移动性管理和 /或载波管理， 使用 RRC连接 重配消息对终端进行测量配置。 为了达到附加测量结果上报的目的， 基站的测量配置内容如下：
测量对象为 fl、 f2、 f3和 f4;
测量 ID为 idl、 id2、 id3、 id4、 id5、 id6、 id7、 id8;
上报配置为 A2、 A3-Pcell ( A3 )、 A3-Scell ( C3 )、 A5-Pcell ( A5 )、
A4。 测量对象、 测量 ID和上报配置的关联关系如表 1所示:
表 1
Figure imgf000013_0001
同时，基站的测量配置中指示 UE在触发特地给测量 ID(例如 id2 ) 的测量上报时， 携带附加测量结果， 例如指示在触发 id2的测量上报 时携带 id3和 id4对应的测量结果， 这些测量结果可以是 id3和 id4 对应的测量上报列表中的小区， 也可以是与 id3和 id4相关的， 不过 仅满足某些条件的小区， 比如 f2和 f3上信道质量大于某个门限的小 区， f2和 f3上的最强小区， 等等， 上报哪些 id3和 id4对应的测量结 果以及上述门限可以通过显式测量配置也可以通过协议预先规定的 方式通知 UE。 本领域普通技术人员应当明白， 基站也可以在测量配 置中指示 UE在触发 id3的测量上报时, 携带 id5、 id6和 id7对应的 测量结果， 测量结果的类型同上， 不再赘述。
本实施例中附加上报的标识（即多载波测量结果中载波测量结果 的标识）可以为测量对象、 测量事件或者测量 id。
如果用测量对象作为附加上报的标识，则基站的测量配置中指示 UE在触发频点 f4相关的测量上报时， 同时携带相应的测量结果， 例 如 f2和 f3相关的测量结果（可以利用频点 f2、 f3或者测量 id标识， 如 id5、 id6对应的测量结果）， 测量结果的类型同上， 不再赘述。 如果用测量事件作为附加上报的标识，则基站的测量配置中指示
UE在触发 A3-Pcell ( A3 )相关的测量上报时， 同时携带其他频点的 测量结果（可以利用频点 fl、 f2、 f2或者测量 id标识， 如 id5、 id6 对应的测量结果， 也可以利用测量事件 A3-Scdl标识）， 测量结果的 类型同上， 不再赘述。
另夕卜， 基站还可以通过测量配置指示 UE附加测量上报的一些限 制信息， 比如允许上报的最大小区数（例如， 4 个）、 上报小区需要 满足的最低门限、 或允许上报的最大频点数（例如， 2 个）、 每个频 点允许上报的最大小区数（例如， 1 个）， 等等， 以达到降低信令开 销的目的。 实施例三
本发明实施例三提供一种多载波系统的测量配置和上报方法，该 方法应用于实施例二中图 4所示的场景。通过预先配置的上报策略规 定（例如在协议中预先规定）， 当网络为 UE配置特定测量事件（例 如 A3-Pcdl ( A3 ) )后, UE在 A3-Pcdl ( A3 )触发的测量上报时， 需 要同时携带附加的测量结果（可以不包括触发此次上报的频点上的小 区）， 这些测量结果可以包括其他测量频点上的最强小区， 当前仍在 其他测量 id对应的上报列表中的小区， 事件 A3-Scdl ( C3 )对应的 测量目标小区， 或者信道质量大于某个门限的小区。
所述多载波测量结果包括以下选项的一种或多种：
附加测量结果对应的测量标识；
附加测量结果中测量上报小区的标识；
附加测量结果中测量上报小区的信道质量。
进一步的， 基站可以在测量配置中增加一个标识（如 lbit, 类似 on/off开关），用来表示是否允许这种附加的测量上报，也可以在测量 配置中增加另外的标识， 用来表示在附件上报时， 是否携带这些小区 对应的测量结果。 同理， 也可以增加其他的标识， 与协议中的预先规 定结合使用， 比如协议中规定了允许上报的最大小区数， 用测量配置 中的标识来表示某次附加上报是否应用该限定。
具体的， 以 A3-Pcdl ( A3 )触发的测量上报时上报多载波聚合小 区为例， 本实施例中， 协议预先规定当网络为 UE 配置测量事件 A3-Pcell ( A3 )后， UE在 A3-Pcdl ( A3 )触发的测量上报时， 需要 同时携带附加的测量结果（不包括触发此次上报的频点上的小区）， 该测量结果是指其他测量频点上的最强小区，最大允许上报的小区个 数为 4。
当 UE由于 id2对于的测量事件 A3-Pcdl ( A3 )触发了测量上报， 则 UE同时携带附加的测量结果， 即 f2、 f3和 f4上的最强小区， 共 3 个。 进一步的， 如果不希望 UE每次触发 A3-Pcdl ( A3 )上报时， 均 携带附加的测量结果， 则可以在测量配置中增加 lbit 的标识， 当该 bit为 '0， 时， 上报时不携带附加的测量结果， 当该 bit为 T 时， 上报时携带附加的测量结果， 该标识可以与测量 id、 测量对象或者上 报配置关联。 实施例四
