技术特征描述以及公开性判断结果对比文件原文引用公开性论述
**技术特征A**:广播该基站的天线配置至用户设备,该天线配置包含垂直方向天线端口与水平方向天线端口 **《直接公开》****段落[0058]**:“eNB can send a cell-specific higher-layer configuration message (e.g., in the MIB (master information block) or a SIB (system information block)) for the indication.”<br><br>**段落[0120]**:“the indicated antenna configuration is used to convey the set of available precoding matrices... The antenna configuration may include... the numbers of the vertical CSI-RS ports and the horizontal CSI-RS ports. For example, the eNB signals an 8×4 antenna configuration to the UE with 0.5λ antenna spacing (e.g., eNB configures 8-port horizontal CSI-RS and 4-port vertical CSI-RS).”D1公开了基站通过小区专用高层配置消息(如MIB或SIB,即广播方式)向UE发送天线配置,该配置明确包含垂直CSI-RS端口数和水平CSI-RS端口数(即垂直与水平方向天线端口)。这与目标专利特征A中基站广播包含垂直与水平方向天线端口的天线配置至用户设备的技术方案完全相同,且作用一致(均用于UE后续的码本选择/PMI反馈)。
**技术特征B**:发送参考信号至该用户设备 **《直接公开》****段落[0041]**:“the network can configure and transmit CSI reference signals (CSI-RS). At the same time, each UE can be configured to feed back estimated precoding matrix indicators (PMI), channel quality information (CQI), and rank information (RI), by receiving and processing the CSI-RS.”D1公开了网络(基站)配置并发送CSI参考信号(CSI-RS)至UE,UE通过接收和处理该CSI-RS来进行信道估计并反馈PMI/CQI/RI。这与目标专利特征B中基站发送参考信号至用户设备的技术方案完全相同。
**技术特征C**:接收由该用户设备反馈的对应于该垂直方向天线端口的垂直预编码器及对应于该水平方向天线端口的水平预编码器 **《直接公开》****段落[0006]**:“The processor is also configured to receive feedback from the UE, the feedback comprising a plurality of vertical precoding matrix indicators (V-PMI) based on the restricted subset of vertical precoding matrices.”<br><br>**段落[0098]**:“In one embodiment of this disclosure, multiple methods are described for configuring codebook subsets for V-PMI. These methods can be used to configure codebook subsets for both H-PMI and V-PMI.”D1公开了eNB接收来自UE的反馈,该反馈包括垂直预编码矩阵指示符(V-PMI)和水平预编码矩阵指示符(H-PMI)。V-PMI对应于垂直方向天线端口,H-PMI对应于水平方向天线端口。这与目标专利特征C完全相同。
**技术特征D**:其中所述垂直预编码器及所述水平预编码器基于从组合码本所选择的预编码器 **《直接公开》****段落[0043]**:“It can be shown that the precoder can be approximated into horizontal and vertical components, V64×n = V8×nV ⊗ V8×nH.”<br><br>**段落[0057]**:“the UE would need to determine which of the N vertical precoding matrices produces the best CQI (in combination with H-PMI) and then indicate this to the eNB (e.g., using a log2N sized bit field).”D1公开了整体预编码器由垂直预编码器和水平预编码器的克罗内克积构成(即组合码本)。UE在选择V-PMI时,是基于其与H-PMI组合(即由组合码本构成的预编码器)产生的CQI来决定的。这意味着反馈的V-PMI和H-PMI是基于从组合码本(V⊗H)中选择的预编码器而确定的。这与目标专利特征D的技术方案实质相同。
**技术特征E**:所述组合码本是从对应于所述垂直方向天线端口的垂直码本和对应于所述水平方向天线端口的水平码本构建的 **《直接公开》****段落[0042]**:“The overall transmit covariance matrix corresponding to all of the 64 antennas in an 8×8 array may be separated into two components using Kronecker decompositions as an approximation, R64×64=R8×8V {circle around (×)} R8×8H.”<br><br>**段落[0043]**:“It can be shown that the precoder can be approximated into horizontal and vertical components, V64×n=V8×nV {circle around (×)} V8×nH.”D1明确公开了通过克罗内克积将整体预编码器(即组合码本)分解为垂直分量(垂直码本)和水平分量(水平码本)。这直接揭示了组合码本是由垂直码本和水平码本构建的,与目标专利特征E完全相同。
**技术特征F**:所述预编码器是基于从所述参考信号所估计的信道状态信息从所述组合码本所选择的 **《直接公开》****段落[0041]**:“each UE can be configured to feed back estimated precoding matrix indicators (PMI), channel quality information (CQI), and rank information (RI), by receiving and processing the CSI-RS.”<br><br>**段落[0057]**:“the UE only measures CQI on the subset restricted matrices and only reports its selection... the UE would need to determine which of the N vertical precoding matrices produces the best CQI (in combination with H-PMI).”D1公开了UE通过接收和处理CSI-RS(参考信号)来估计信道状态信息(CSI),并基于CQI(信道质量信息,属于CSI)从码本(组合码本)中选择PMI(预编码器)。这与目标专利特征F的技术方案完全相同。
**技术特征G**:及基于所接收的垂直预编码器及水平预编码器,使用对应于该垂直方向天线端口的垂直码本及对应于该水平方向天线端口的水平码本来重构预编码器 **《直接公开》****段落[0043]**:“V64×n=V8×nV {circle around (×)} V8×nH.”<br><br>**段落[0006]**:“The processor is also configured to receive feedback from the UE, the feedback comprising a plurality of vertical precoding matrix indicators (V-PMI) based on the restricted subset of vertical precoding matrices.”D1公开了整体预编码器由垂直预编码器(V8×nV)和水平预编码器(V8×nH)的克罗内克积构成。eNB的功能包括接收V-PMI(及H-PMI),其必然需要基于对应的垂直码本和水平码本来重构完整的预编码器(即执行克罗内克积运算),这是利用2D码本进行通信的基础。这与目标专利特征G的技术方案实质相同。
**技术特征H**:其中所述重构预编码器包含使用克罗内克积函数将该垂直码本及该水平码本组合在一起 **《直接公开》****段落[0043]**:“V64×n=V8×nV {circle around (×)} V8×nH.”D1在重构预编码器的公式中明确使用了克罗内克积符号“{circle around (×)}”(Kronecker product function)来组合垂直码本和水平码本,与目标专利特征H完全相同。
**技术特征I**:其中该垂直码本与该水平码本是...3GPP标准TS36.211及TS36.213规定的相应天线端口数的码本 **《直接公开》****段落[0020]**:“The following documents and standards descriptions are hereby incorporated into this disclosure as if fully set forth herein: (i) 3GPP Technical Specification No. 36.211, version 10.1.0, “E-UTRA, Physical channels and modulation”... (iii) 3GPP Technical Specification No. 36.213, version 10.1.0, “E-UTRA, Physical Layer Procedures”.”<br><br>**段落[0075]**:“In the Release-10 specification of LTE, a double codebook structure is used for the 8-Tx antenna configuration.”D1明确引用3GPP TS 36.211和36.213作为标准码本的定义依据,并基于LTE Release 10中规定的码本(即这些标准中规定的码本)进行讨论,例如8-Tx的双码本结构。这与目标专利特征I完全相同。
**技术特征J**:其中该天线配置包含8、16、32或64个天线端口 **《直接公开》****段落[0042]**:“The overall transmit covariance matrix corresponding to all of the 64 antennas in an 8×8 array...”<br><br>**段落[0057]**:“For example, an 8×8 antenna array at the eNB decomposes the precoder into 8×1 vertical and 8×1 horizontal vectors.”<br><br>**段落[0121]**:“For example, the eNB signals an 8×4 antenna configuration to the UE with 0.5λ antenna spacing (e.g., eNB configures 8-port horizontal CSI-RS and 4-port vertical CSI-RS).”D1广泛公开了多种天线配置,包括8端口(8x1,1x8)、16端口(由8x2、4x4等隐含支持)、32端口(8x4)和64端口(8x8),完全覆盖了目标专利特征J所列出的天线端口数。
