  • the NCT is different from the traditional carrier, the requirements for the UE to measure the NCT are different.

Therefore, in the 3GPP discussion, many companies believe that the eNB (evolved Node B) needs to transmit the carrier type information of the cell to the UE.

Description

说 明 书 用于获取或发送小区栽波类型信息的方法、 基站、 网络管理实体、 终端和 *** 技术领域
本发明涉及无线通信技术领域, 具体而言, 涉及用于获取或发送小区 载波类型信息的方法、 基站、 网络管理实体、 终端和***。 背景技术
3GPP Release 11 中, 在载波聚合 (Carrier Aggregation, CA)的场景下 引入了新载波类型 (New Carrier Type , NCT)用于提升频谱利用率和能量利 用率。 目前研究的 NCT 分为两类: 独立 NCT(stand-alone NCT)和非独立 NCT(non stand-alone NCT)。 Stand-alone NCT可以不依赖于一个传统载波 而独立运作, 而 non stand-alone NCT必须关联到一个能后向兼容的传统载 波才能进行工作, 即无法独立运作。 根据 non stand-alone NCT是否与其关 联的传统载波同步, 又可以分为同步 NCT和非同步 NCT , 同步 NCT和其 关联的传统载波在时域和频域上始终保持同步, 而非同步 NCT 和其关联 的传统载波在时域和频域上不同步。
基于目前 3GPP 标准得到的结论, 对于非同步 NCT 采用后向兼容的 Release 8 CRS传输机制, 但 CRS的发送密度降低为 5ms周期, 同时非同 步 NCT 的同步信号 PSS(Primary Synchronization Signal )/SSS(Secondary Synchronization Signal)采用 Release 8的同步信号序列。
因为 NCT与传统载波的不同, 使得 UE进行对 NCT的测量时的需求 会不同, 也就是说, UE 对一个载波或者小区进行测量之前, 需要先获知 该载波或小区是传统载波还是 NCT , 从而采用不同的测量方式并应用相 应的测量需求, 因此, 在 3GPP 讨论中, 不少公司认为 eNB ( evolved Node B , 演进型基站) 需要将小区的载波类型信息发送给 UE, UE根据所 测量载波是否是 NCT和 /或其他相关的载波信息进行相应的测量。 以图 1 所示的场景为例, 在基于小小区 ( small cell ) 和宏基站 ( Macrocell ) 的异构网络中进行部署。 其中, 宏基站 eNBl 和宏基站 eNB2为传统宏基站, 一个 non stand-alone NCT布署的小小区 102关联到 一个传统小区即宏基站 eNBl 下的一个小区上。 宏基站 eNBl 与宏基站 eNB2之间为 X2接口, 宏基站 eNB l和其关联的 NCT小区 (此处即上述 NCT部署的小小区 102 )之间可能是 X2接口, 也可能是自定义的内部接 口或新定义的标准接口。 宏基站 eNB2 的邻居小区为宏基站 eNBl 的服务 小区和小小区。
当宏基站 eNB2指示其小区内的 UE对邻居小区进行测量时, 需要将 所测量对象 /小区的载波类型以及载波类型信息等告知 UE, 也就是说宏基 站 eNB2在告知 UE这些信息前需要先获取这些信息, 因而所存在的问题 是宏基站 eNB2如何获取所需要的信息。
因此, 基于上述提出的问题, 需要一种新的用于宏基站获取小区载波 类型信息的技术策略, 可以使基站准确了解其邻居小区的载波部署情况, 以便据此对被基站服务的终端进行测量参数的配置, 实现终端对邻居小区 的测量。 发明内容

实施例五
图 26 示出了根据本发明的又一个实施例的基站获取小区载波类型信 息的示意图。 如图 26 所示, 在根据本发明的又一个实施例的基站获取小区载波类 型信息的技术方案中, 由基站 2604从被基站 2604服务的终端 2602处, 获取小区载波类型信息。
由于在现有机制中, 处于连接态的终端 2602进行基站 2604所配置的 测量时, 基站 2604对终端 2602 进行的测量配置中, 通过指示终端 2602 所需要测量的频率和小区列表信息, 以指示对应的测量对象。 如果终端 2602 在所配置的频率上测量到一个不属于所配置的小区列表中的小区, 则该小区称为被发现小区(Detected cell)。
在本实施例中, 具体地, 这里的被终端 2602 获取小区载波类型信息 的小区可以为基站 2604配置的小区, 也可以为被发现小区。 当终端 2602 测量得到一个小区时, 若终端 2602识别出该小区为 NCT并能获得该 NCT 小区的小区载波类型信息, 则终端 2602 在上报测量结果时, 除了将该小 区 的 RSRP (Reference Signal Received Power)/RSRQ(Reference Signal Received Quality)和 PCI(Physical Cell ID)上报之外, 还将该 NCT小区的小 区载波类型信息一起上报给基站 2604。
具体地, 终端 2602 可以基于小区标识、 同步信号的位置或序列、 小 区***广播信息中的小区类型标识、 ***信息的位置、 下行控制信道的位 置、 下行参考信号的位置等信息中的一种或多种来识别出一个 NCT 小区 和 /或获得该 NCT小区的小区载波类型信息。
