Abstract

本发明实施例提供一种信道状态信息的测量方法、用户设备及基站,该测量方法包括:基站为用户设备选择进行多点协作传输的一个或多个协作传输点;对于每个基站和每个协作传输点,独立配置用于信道状态信息反馈的测量子集,使得用户设备根据测量子集进行测量。通过本发明实施例,对每个参与协作的小区或传输点进行单独的信道状态信息反馈配置,可以使用统一的反馈信息结构设计,使得针对多传输点或者多小区的信道反馈信息既能够服务于单小区的传输,也能够服务于多小区的传输。

Description

信道状态信息的测量方法、 用户设备及基站 技术领域
本发明涉及一种通信领域,特别涉及一种信道状态信息的测量方法、 用户设备及基站。 背景技术 增强的长期演进 (LTE-A, Long Term Evaluation Advanced) 系统在 传统同构网络的基础上引入低功率发送节点, 组成异构网络。 可以由宏 小区 (Macro Cell), 毫微微蜂窝 (Femto Cell) , 微微蜂窝 (Pico Cell), 远端无线头 (RRH, Remote Radio Head )、 中继器 (Relay) 组成。
为了改善 LTE-A系统下的小区覆盖和用户体验, 提高系统的吞吐量 和用户的数据传输速率, 多点协作 (CoMP, Coordinated Multiple Points) 技术已经被引入。 这种技术利用多个地理位置上分散的传输点对用户协 同传输数据, 增强小区边缘用户的性能, 改进了小区的覆盖, 提高了小 区边缘的吞吐量和系统的吞吐量, 提高了用户的性能体验。
在 CoMP技术中, 同一小区的不同传输点可以进行协作发送。 图 1 是多点协作系统中同一小区的不同传输点进行协作的示意图, 如图 1 所 示,同一小区的 eNB 101和 RRH 102可以协作为用户设备 104服务, eNB 101和 RRH 103可以协作为用户设备 105服务。
此外, 不同小区的不同传输点也可以进行协作发送。 图 2是多点协 作系统中不同小区的不同传输点进行协作的示意图, 如图 2所示, 不同 小区的 eNB/RRH 201、 eNB/RRH 202可以协作为用户设备 203服务。
为选择最优的协作传输点, 基站端需获得各个传输点到用户的下行 信道信息, 通常包括信道质量信息 (CQI, Channel Quality Information) , 预编码矩阵索引 (PMI, Precoding Matrix Index ) 以及秩(Rank) , 从而根 据一定的优化准则, 挑选出最优的一个或者多个传输点。 为保证后相兼 容且更灵活的调度, 基站端需具备回退到传统蜂窝的单点发送的能力, 从而要求用户在反馈信道信息时, 不仅报告多点协作发送下的下行信道 信息, 也需报告传统单点发送时的下行信道信息。
在异构网络(Heterogeneous Network)中区别于传统的蜂窝网络的某 些异构网络结点被引入。 这些异构的结点, 比如家庭基站 HeNB(Home eNodeB), 热点覆盖小区 Pico-cell等, 使用较低的发射功率, 对特定的区 域或者用户进行覆盖, 组网方式相对灵活, 如果部署合理, 用户体验会 有较大幅度的提高。 并且在 Macro-Pico场景下, 标准中已经引入了几乎 空白子帧 (ABS, Almost Blank Subframe ) 来加强小区间的干扰协调 ( elCIC, enhanced interference coordination and interference cancellation )。
但是, 在实现本发明实施例的过程中, 发明人发现: 目前对于信道 状态信息反馈仅采用两个测量子集 ( measurement reference resource subsets) , 对于每个参与协作的小区或传输点并没有进行单独的信道状态 信息 (CSI, Channel State Information) 反馈配置。
图 3是现有技术中 ABS子帧和测量子集的关系示意图,如图 3所示, 一个测量子集 ( Measurement subset 0 ) 对应 ABS , 另一测量子集 (Measurement subset 1 ) 对应普通子帧 (Normal Subframe )
由此, 目前对于各种 CoMP技术没有使用统一的反馈信息结构设计, 即针对多传输点或者多小区的信道反馈信息不能够既服务于单小区的传 输, 也服务于多小区的传输。
应该注意, 上面对技术背景的介绍只是为了方便对本发明的技术方 案进行清楚、 完整的说明, 并方便本领域技术人员的理解而阐述的。 不 能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技 术方案为本领域技术人员所公知。 发明内容

具体实施方式
参照附图, 通过下面的说明书, 本发明的前述以及其它特征将变得 明显。 在说明书和附图中, 具体公开了本发明的特定实施方式, 其表明 了其中可以采用本发明的原则的部分实施方式, 应了解的是, 本发明不 限于所描述的实施方式, 相反, 本发明包括落入所附权利要求的范围内 的全部修改、 变型以及等同物。
目前, CoMP传输方案包括联合处理 (JP, Joint Processing) 和合作 调度 /波束赋形 (CS/CB, Coordination Scheduling/Beamforming ) 前者表 示同时可以有多个传输点同时有给用户设备的发送数据, 在多个点中动 态的选择一个或多个传输点为用户设备发送数据; 后者表示同时只有一 个传输点为用户设备发送数据。 其中, 传输点的类型可以是传统的宏蜂 窝基站, 或者是 RRH, 还可以是 Pico基站等异构结点; 可能是高功率节 点也可能是低功率节点。
根据不同的 CoMP技术, 用户的反馈信息不尽相同, 但均需要反馈 传统单点发送 (Non-CoMP) 下的 CSI、 以及 CoMP发送下的 CSI。 对于 JP发送, 接收信号可由下式表示:
Figure imgf000007_0001
其中, w* 是在 JP发送中协作发送点 b使用的预编码矩阵, H 为协 作发送点 b到用户的信道, x为发送数据, n为噪声。
用户需要分别反馈各个发送点的预编码矩阵^^(6),并反馈基于上报的 预编码矩阵, 由公式 (1 ) 所对应的量化信噪比, 即 CQI。 同时, 用户也 需反馈仅单点发送时的 CSI, 即由公式 (2) 所对应的预编码矩阵和量化 信噪比。
y,
Figure imgf000007_0002
+ n 当 CoMP应用于异构网络中, 一种可能的场景是 elCIC和 CoMP同 时运作。 在这个时候部分宏站可能会配置 ABS, 这个时候会出现下面的 情况: 在 ABS中实施 CoMP, 即多个传输点或者小区进行协作传输的时 候, 其中至少有一个小区或者传输点配置了 ABS; 或者, 在 non-ABS中 实施 CoMP, 即多个传输点或者小区进行协作传输的时候,其中没有小区 或者传输点配置了 ABS。 目前针对如上的情况, 多点协作系统没有多小 区的测量参考资源 (measurement reference resource ) 的处理方案。
本发明实施例提供一种信道状态信息的测量方法, 图 4是本发明实 施例的测量方法的流程图, 如图 4所示, 在多点协作系统中的基站侧, 该测量方法包括:
步骤 401,基站为用户设备选择进行多点协作传输的一个或多个协作 传输点;
步骤 402,对于每个基站和每个协作传输点,独立配置用于信道状态 信息反馈的测量子集, 使得该用户设备根据测量子集进行测量。
在本实施例中, 基站应该理解为广义上的网络侧基站, 可以是宏小 区 (Macro Cell) 基站, 也可以是微微蜂窝小区 (Pico Cell) 基站, 还可 以是 RRH。 协作传输点可以包括单独的小区或者基站、 或者 RRH、 或者 天线端口等。 但不限于此, 可以根据实际情况确定具体的类型。
在本实施例中, 对于该基站和每个协作传输点, 均可以配置测量子 集。 该测量子集可以指示用户设备使用哪些资源 (包括时域和频域) 中 的参考符号进行信道估计和信噪比测量。
其中, 基站的测量子集可以包含: 对应于一个或多个协作传输点的
ABS 的资源信息; 协作传输点的测量子集可以包括: 对应于其他协作传 输点和该基站的 ABS的资源信息。
由此, 通过对每个参与协作的小区或传输点进行单独的信道状态信 息反馈配置, 可以使用统一的反馈信息结构设计。 并且, 可以在尽可能 干扰小的资源上进行 CSI测量, 能够增加反馈的精度, 灵活性, 并且减 小下行的开销。
图 5是本发明实施例的测量方法的又一流程图, 如图 5所示, 该测 量方法具体包括: 步骤 501,基站为用户设备选择进行多点协作传输的一个或多个协作 传输点。
步骤 502, 基站将配置了 ABS的调度模式向协作传输点发送, 并接 收协作传输点发送的配置了 ABS的调度模式。
在本实施例中, 基站和协作传输点均可具有配置了 ABS的调度模式
(ABS pattern),基站和各个协作传输点之间可以交互各自的配置了 ABS 的模式。 可采用现有技术实现, 此处不再赘述。
步骤 503, 基站根据配置了 ABS的调度模式来配置测量子集。
在本实施例中, 可以根据配置了 ABS的调度模式, 为基站和各个协 作传输点配置测量子集。 其中, 基站的测量子集可以包含: 对应于一个 或多个协作传输点的 ABS的资源信息;协作传输点的测量子集可以包括: 对应于其他协作传输点和该基站的 ABS的资源信息。
以下以 Cell#l对应基站、 Cell#2和 Cell#3对应协作传输点为例, 对 测量子集的配置进行详细说明。 其中, 用户 UE#1 归属于小区 Cell#l, Cell#2和 Cell#3 同时和 Cell#l 为 UE#1协作传输。 Cell#l配置了 ABS pattern P#l , Cell#2配置了 ABS pattern P#2, Cell#3配置了 ABS pattern P#3。
那么 Cell#l为 UE#1配置 Cell#l的测量子集可以为 (P#2nP#3); Cell#l 为 UE#1配置 Cell#2的测量子集可以为 (P#i nP#3); Cell#l为 UE#1配置 Cell#3的测量子集可以为 (Ρ#1 ΠΡ#2)。
Figure imgf000009_0001
其中, 0表示对应普通子帧的资源信息, 1表示对应 ABS的资源 、。 则为 UE#1配置的 Cell#l的测量子集 (Ρ#2ΠΡ#3) 为: 为 UE#1配置的 Cell#2的测量子集 (Ρ#1 ΠΡ#3) 为: 为 UE#1配置的 Cell#3的测量子集 (Ρ#1 ΠΡ#2) 为: 本发明实施例采用这种方法, 可以使得三个小区之间的干扰在 UE 进行信道测量的时候尽可能的小, 以此来减小信道测量的误差。 并且每 个 cell单独的 pattern的配置也可以将更多小区 ABS pattern考虑进来,进 而选取相对优化的测量参考资源。
并且, 采用这种方式, 为规避干扰(例如对 CSI-RS的干扰)所作的 下行的静默 (muting, 例如 PDSCH muting) 也会减少, 从而减小下行的 开销。
值得注意的是, 以上实例仅对配置测量子集的优选实施方式进行了 示意性说明, 但本发明不限于此, 例如对于 UE#1配置的 Cell#l 的测量 子集也可配置为 P#2, 即仅包含对应于 Cell#2的 ABS的资源信息, 而不 包含对应于 Cell#3的 ABS的资源信息。
此外, 在具体实施时, 也可由基站或协作传输点各自配置对应的测 量子集。 例如 Cell#l为 UE#1配置 Cell#l 的测量子集; Cell#2为 UE#1 配置 Cell#2的测量子集; Cell#3为 UE#1配置 Cell#3的测量子集。
在本实施例中, 如图 5所示, 在步骤 503之后, 所述测量方法还可 以包括:
步骤 504, 基站向用户设备发送配置后的测量子集。
在具体实施时, 基站可通过高层信令向用户设备发送测量子集, 使 得用户设备根据测量子集进行测量, 并进行周期上报。
或者,在具体实施时,基站还可以通过下行控制信息(DCI, Downlink
Control Information) 向用户设备发送测量子集, 以触发用户设备根据测 量子集进行测量, 并进行非周期上报。
此外, 在具体实施时, 如果在步骤 503 中, 测量子集由基站或协作 传输点各自配置, 则基站或协作传输点可以各自向用户设备发送对应的 测量子集, 以触发用户设备进行测量, 并进行周期上报或非周期上报。
本发明实施例还提供一种基站, 与上述信道状态信息的测量方法相 同的内容, 此处不再赘述。 值得注意的是, 该基站应该理解为广义上的 网络侧基站, 可以是宏小区 (Macro Cell) 基站, 也可以是微微蜂窝小区 (Pico Cell) 基站, 还可以是 RRH等等。
