Description
本申请涉及无线通信技术领域，例如涉及一种上行数据信道多天线合并方法和装置。
SRS(Sounding Reference Signal，探测参考信号)是参考信号的一种，由UE(终端)上行发送，基站上行检测，用来测量上行信道质量。基站上行将测量结果发给调度器，由调度器进行频选调度。所谓频选调度，就是在调度的时候，调度器根据信道质量情况，选择信道质量较好的频带用于UE上行发送PUSCH(Physical Uplink Shared Channel，物理上行共享信道)信号，避开SINR(Signal to Interference plus Noise Ratio，信号与干扰加噪声比)较差的频带。使用SRS主要可以用来进行TA、SINR、UE测速，以及波速赋型权值计算等。
UE发射PUSCH信号经过空口到达基站，基站对UE发射的PUSCH信号进行解调，解调性能依赖于基站上行接收天线数及上行空口信道质量。为了满足日益增长的无线通信中对上下行流量的需求，应用大规模多天线阵列技术的一体化室外型基站越来越得到广泛研究和应用。该基站支持的天线数有32、64、128、256甚至更多。而在商用系统中一个基站还可能需要支持多载波，每个载波还有支持用户数的限制，为了保证每个载波的解调性能，支持的天线数不能减少，这样的话对于系统的处理能力将会是一个很大的考验。为了在一体化基站中更加灵活的设计支持载波数和用户能力数，同时为了保证解调性能就需要对上行业务数据信道PUSCH进行多天线合并，那么，怎么样合并才不会影响PUSCH多天线的解调性能正是本申请所要解决的技术问题。

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，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做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
实施例一
本发明实施例提供一种在现有大规模多天线阵列系统中既能保证PUSCH解调性能又能降低系统处理资源消耗的上行数据信道多天线合并方法，应用于基站侧，如图1所示，所述方法包括如下步骤：
步骤S101，对基站所有上行天线接收的SRS信号进行信道估计，并根据所述信道估计和天线校正权值，确定每根上行天线的合并补偿权值；其中，上行天线的合并补偿权值反应了上行信道幅度及相位偏移。
确切地讲，本实施例中，对基站所有上行天线接收的SRS信号进行信道估计，得到每根上行天线每个资源块RB位置的信道估计，并根据每根上行天线每个RB位置的信道估计和每根上行天线的天线校正权值，确定每根上行天线每个
RB位置的合并补偿权值。也就是说，本实施例中，以RB为单位，计算各上行天线的合并补偿权值。
在本发明的一个实施例中，根据信道估计和天线校正权值，确定每根上行天线的合并补偿权值的方式包括：
首先，根据每根上行天线的信道估计H，计算得到每根上行天线的天线补偿权值
其中，H*为信道估计H的共轭，||H||为信道估计H的模；
然后，根据每根上行天线的天线补偿权值
和上行天线的天线校正权值，计算得到每根上行天线的合并补偿权值
其中，WAC为天线校正权值。其中，天线校正权值可以根据目前已知的计算方式计算得到，本发明实施例不对其计算方式进行唯一限定。
步骤S102，根据每根上行天线的合并补偿权值，对各上行天线的信号进行相位对齐，并按照配置的合并方案，进行天线间的合并。
其中，根据每根上行天线的合并补偿权值，对各上行天线的信号进行相位对齐，指：将每根上行天线的信号乘以其天线的合并补偿权值。
本发明实施例中，所述按照配置的合并方案，进行天线间的合并，包括：
按照配置的合并方案，对需要合并的上行天线的信号进行累加求平均，实现天线间的合并。
其中，合并方案可以根据实际需求以及系统的载波数、用户数、处理能力等灵活配置，比如某基站设备设计处理能力支持单个载波256天线，针对某些场景又需要支持双载波，每个载波的用户数还不能降低，同时还需要保持上行的解调性能及流量要求，基于原有设备就可以将合并方案配置为对每个载波进行256天线合并成128天线，单个载波实际处理128天线。
采用本发明实施例所述方法的多天线合并技术，不仅可以保证合并后的PUSCH解调性能，同时还能够满足商用系统中对于多载波和用户数的要求等。
实施例二
本发明实施例提供一种上行数据信道多天线合并方法，其从公开更多的技术细节角度出发，对本发明实施例提出的多天线合并方案进行更详细的阐述。

本实施例中，在进行多天线合并时，实施原理为：基站收到UE发送的SRS信号后，对收到的SRS信号首先进行信道估计，根据信道估计计算上行天线合并补偿权值，并利用各上行天线的合并补偿权值，对各上行天线接收到的PUSCH天线信号进行相位对齐，在相位对齐后，根据配置的合并方案，进行天线合并，合并后的天线数据送到解调模块进行解调。
本实施例中，多天线合并的实施过程为：
首先，获取基站上行所有接收天线的SRS信号，对该SRS信号进行信道估计，得到每根天线每个RB(Resource Block，资源块)位置的信道估计H。
其次，计算上行天线补偿权值。根据前一个步骤得到的H值，根据公式
计算得到每个天线每个RB位置的PUSCH上行天线补偿权值。该权值反映了UE到基站每根天线的信道质量情况。
第三，基于计算出来的天线补偿权值，根据公式
计算得到每根天线的合并补偿权值，并将每根天线的信号乘以其合并补偿权值，实现对各天线信号的相位对齐。其中，WAC为天线校正权值。
第四，按照配置的合并方案，对需要合并的各天线的天线信号进行累加求平均得到PUSCH天线合并后的信号。
第五，对合并后的PUSCH天线级的数据进行解调和译码。
本实施例所述方案，能够灵活的根据基站处理能力和资源情况，针对商用场景需求，灵活的配置天线合并方式，达到在不降低PUSCH解调性能的情况下灵活支持载波数和用户数。
