在标准化发展过程中MIMO技术的维度不断扩展。在LTE Rel-8中，最多可以支持4层的MIMO传输。在Rel-9中增强MU-MIMO(Multi-User MIMO，多用户多输入多输出)技术，TM(Transmission Mode，传输模式)-8的MU-MIMO传输中最多可以支持4个下行数据层。在Rel-10中将SU-MIMO(Single-User MIMO，单用户多输入多输出)的传输能力扩展至最多8个数据层。
产业界正在进一步地将MIMO技术向着三维化和大规模化的方向推进。目前，3GPP已经完成了3D信道建模的研究项目，并且正在开展eFD-MIMO(evolved Full-Dimension MIMO，增强全维度MIMO)和NR MIMO(New Radio MIMO，新空口MIMO)的研究和标准化工作。可以预见，在未来的5G移动通信系统中，更大规模、更多天线端口的MIMO技术将被引入。
Massive(大规模)MIMO技术使用大规模天线阵列，能够极大地提升系统频带利用效率，支持更大数量的接入用户。因此各大研究组织均将massive MIMO技术视为下一代移动通信系统中最有潜力的物理层技术之一。
在massive MIMO技术中如果采用全数字阵列，可以实现最大化的空间分辨率以及最优MU-MIMO性能，但是这种结构需要大量的AD/DA(模数/数模)转换器件以及大量完整的射频-基带处理通道，无论是设备成本还是基带处理复杂度都将是巨大的负担。
为了避免上述的实现成本与设备复杂度，数模混合波束赋形技术应运而生，即在传统的数字域波束赋形基础上，在靠近天线系统的前端，在射频信号上增加一级波束赋形。模拟赋形能够通过较为简单的方式，使发送信号与信道实现较为粗略的匹配。模拟赋形后形成的等效信道的维度小于实际的天线数量，因此其后所需的AD/DA转换器件、数字通道数以及相应的基带处理复杂度都可以大为降低。模拟赋形部分残余的干扰可以在数字域再进行一次处理，从而保证MU-MIMO传输的质量。相对于全数字赋形而言，数模混合波束赋形是性能与复杂度的一种折中方案，在高频段大带宽或天线数量很大的系统中具有较高的实用前景。
在现在的LTE系统中，允许UE(User Equipment，UE，用户设备，也可以称之为终端)有不同的产品成本和应用，那么通过UE来上报自身的接入网能力，网络侧就可以提供与UE能力相匹配的更好服务。也就是说，网络侧在做各种事件判决或者执行各种算法时，均需知道UE的能力，才能做出最合适的判决。
在UE EUTRA capability(UE的演进的UMTS陆面无线接入能力)中，包含如下消息内容：
a、接入层release：设置为UE所支持的3GPP版本号；
b、UE category(种类)；
c、PDCH(分组数据信道)参数：描述UE所支持的ROHC profile(Robust Header Compression profile，鲁棒头压缩简档)组合，以及UE支持的最大的头压缩context sessions(上下文会话)的个数等；
d、物理层参数：包括UE是否支持天线选择、FDD(频分双工)下UE是否对下行支持UE specific RS(特定参考信号)等；
e、RF(射频)参数：指示UE能够支持的EUTRA频带、UE支持半双工还是全双工等；
f、测量参数：包括是否需要measurement gaps(测量间隙)等；
g、Feature group indicators(FGI，特征组指示)：在specific indicator(明确指示)为“True”时，支持所有functionality(功能)的执行和测试，否则为“false”，设置所有不支持的functionality为“false”。
h、InterRAT(异系统小区切换)参数：指的是UE对于异系统的支持能力，这是网络侧判决UE能否进行互操作的重要依据。
在UE EUTRA capability中，UE category的参数定义了UE上下行能力，其中包括：
下行物理层参数值系列包括：一个TTI(发送时间间隔)中接收到的DL-SCH(下行共享信道)传输块总的最大比特数、一个TTI中接收到的一个DL-SCH传输块内包含的最大比特数、软信道比特数总数、下行支持的最大空间复用层数等。
上行物理层参数值系列包括：一个TTI中接收到的UL-SCH(上行共享信道)传输块总的最大比特数、一个TTI中接收到的一个UL-SCH传输块内包含的最大比特数、上行是否支持64QAM(相正交振幅调制)等。
L2缓冲器大小等。
需要说明的是，UE的能力上报是UE第一次ATTACH(附着)或TAU(跟踪区更新)的时候，UE主动上报自己的能力，此属于NAS(非接入层)过程。而网络侧在RRC(无线资源控制)规范中，也有UE能力查询过程，获取并传递UE能力。具体如下：
1)首先，UE开机，与网络建立同步和接入，即：
1.1、UE发送RA preamble(随机接入前导)给基站；
1.2、基站发送RA response(随机接入应答)给UE；
1.3、UE发送RRCConnectionRequest(RRC连接请求)给基站；
1.4、基站发送RRCConnectionSetup(RRC连接建立)给UE；
1.5、UE发送RRCConnectionSetupComplete(RRC连接建立完成)给基站，完成RRC连接的建立。
2)基站发送Initial UE message(初始化UE消息)给MME(移动性管理实体)，包括：Attach Request(附着请求)、PDN connectivity request(分组数据网连接请求)消息等。
3)MME发送Initial context setup request(初始化上下文建立请求) 给基站，包括：Attach Accept(附着接受)、Activate default EPS bearer context request(激活默认EPS(演进的分组系统)承载上下文请求)，从而完成S1的连接，完成这些过程就标志着NAS signaling connection(非接入层信令连接)建立完成。
4)如果在上述消息Initial context setup request中携带了UE Radio Capability IE(无线能力信息元素)，则基站不会发送UE Capability Enquiry(能力查询)消息给UE。否则，基站会发起UE能力查询过程，这在第一次入网的过程中经常看到。即：
4.1、基站发送UE Capability Enquiry给UE；
4.2、UE发送UE Capability Information(能力信息)给基站。
基站再发送UE Capability info Indication(能力信息指示)给MME。也就是UE上报自身无线能力信息，基站再给核心网上报UE的无线能力信息。
由描述可知，massive MIMO使用数字模拟混合波束赋形技术时，将会设计相应的天线阵列结构，例如增加panel(面板)，每个panel可以连接到相应的baseband unit(基带单元)上，发送各自的模拟波束，而panel的阵列之间可以再通过数字赋形技术，从而来实现覆盖特定的地理区域。
相关技术中的UE能力设计和上报中，没有这种天线阵列结构信息的消息，那么在后续使用过程中，也就无法在利用更多天线进行用户调度和数据传输时提供给系统更高效的波束管理、更精准的波束对齐、更优化的多用户调度和多数据流传输。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完成地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
如图1所示，为本公开一些实施例的终端信息上报方法的流程图。下面结合本图具体说明终端信息上报方法的实现过程。
本公开一些实施例提供一种终端信息上报方法，应用于一终端，包括：
步骤101，发送终端天线结构的设置参数给基站；其中，所述设置参数包括基带参数和/或射频参数。
需要说明的是，所述基带参数包括：终端支持的收发器单元(TxRU)个数；
所述射频参数包括：面板(panel)个数、每个面板支持的频点信息、每个面板支持的波束(beam)个数和每个面板上的天线阵列极化方向的个数中的一个或者多个。
例如，图2为对于大规模天线阵列的结构示意图，图2中将全部天线阵列分为不同的panel，每个panel由双极化阵列组成，每种线形代表一个极化方向的天线阵元。其中，每个panel所包含的天线阵元数量、支持的高、低频段等均可以不同。
本公开一些实施例的终端信息上报方法，终端通过将自身天线结构的设置参数给基站，使得网络侧了解了终端上的天线阵列结构信息，在后续使用过程中，网络侧利用更多天线进行用户调度和数据传输时，能提供给系统更高效的波束管理、更精准的波束对齐、更优化的多用户调度和多数据流传输。
如图3所示，为本公开一些实施例的终端信息上报方法的流程图。下面结合本图具体说明终端信息上报方法的实现过程。
本公开一些实施例提供一种终端信息上报方法，应用于一终端，包括：
步骤301，在随机接入过程中，发送包括终端的第一类属性信息的反馈消息给基站；其中，所述终端的第一类属性信息包括终端天线结构的设置参数。
需要说明的是，本公开一些实施例中所说的第一类属性信息指的是终端天线结构的设置参数，而终端的其他能力信息可以称之为第二类属性信息，该第二类属性信息与背景技术中所提到的UE EUTRA capability所包含的参数相同， 在此不再详细说明。
本步骤中，实现的是将终端天线结构的设置参数在随机接入的过程中发送给基站。
需要说明的是，所述基带参数包括：终端支持的收发器单元个数；所述射频参数包括：面板个数、每个面板支持的频点信息、每个面板支持的波束个数和每个面板上的天线阵列极化方向的个数中的一个或者多个。所述反馈消息可以为随机接入前导消息(RA Preamble)，也可以为无线资源控制(RRC)连接请求消息。
需要说明的是，为了使得基站能较好发送下行数据，所述终端需要向基站反馈最优下行发送波束，本公开一些实施例中终端采用两种方式进行最优下行发送波束的上报。
方式一、
在步骤301之前，本公开一些实施例的所述终端信息上报方法，还包括：
在随机接入之前，根据对基站发送的同步信号的接收强度，确定每个面板测量得到的最优下行发送波束信息。
进一步地，步骤301的实现方式为：在随机接入过程中，发送同时包括终端的第一类属性信息以及每个面板测量得到的最优下行发送波束信息的反馈消息给基站。
需要说明的是，本方式一是在随机接入之前，终端根据基站的同步信号，每个面板分别测量出其对应的最优下行发送波束，该最优下行发送波束指的是，终端测量得到的信号强度最大的下行发送波束。在随机接入时，终端将每个面板的最优下行发送波束以及终端的第一类属性信息一同上报给基站。
上述方式一在实际应用中的具体实现过程如图4所示：
步骤401，终端开机，根据基站的同步信号，确定最优下行接收波束(Rx beam)和发送波束(Tx beam)。
需要说明的是，UE在开机时，通过搜索PSS(主同步信号)和SSS(辅同步信号)等信号，与网络侧实现同步，在同步期间，基站通过多个beam发送同步信号，UE利用多个panel分别进行同步信号的beam搜索，即每个panel上的模拟波束进行空间方向的轮流接收，找到该panel的最优下行Rx beam和Tx beam。
步骤402，终端进行随机接入，在随机接入中的上行信道中携带第一类属性信息以及每个panel对应的最优下行Tx beam。
需要说明的是，该上行信道可以为RACH(Random Access Channel，即随机接入信道)。这样，基站就可以获知UE的天线结构的panel信息、所支持beam信息以及最优下行Tx beam等信息。
步骤403，在建立无线资源控制(RRC)连接后，终端上报第二类属性信息。
需要说明的是，基站根据所述UE第一类属性信息，采用每个panel的最优Tx beam发送随后的随机接入下行信息，UE采用panel最优Rx beam接收该下行信息。从而完成随机接入，建立RRC连接，然后进行UE的第二类属性信息的上报。
还需要说明的是，基站在进行数据传输时，使用UE各panel的最优下行Tx beam承载下行信道，UE则使用每个panel最优下行Rx beam进行数据接收。这里的数据传输所使用的beam，对于每个panel的每个极化方向阵列，可以使用不同的beam。而且，如果每个panel支持的频点不同，则需要使用各自的频点来发送beam上的数据。例如，UE有2个panel，每个panel上的阵列只有一个极化方向，则基站可以使用空间复用技术，发送2路并行数据流，每个数据流使用每个panel对应的最优beam承载，或者2路数据流是经过预编码后再使用每个panel对应的最优beam承载。UE则使用两个panel分别接收这2路数据流。
方式二、
在步骤301之后，本公开一些实施例的所述终端信息上报方法，还包括：
在随机接入过程中或随机接入之后，根据对基站依据所述设置参数发送的匹配波束的接收强度，确定每个面板测量得到的最优下行发送波束信息。
需要说明的是，因终端已经发送了自身的天线结构的设置参数，基站在发送波束时就可以按照终端的天线结构的设置方式进行发送，终端在接收时，也按照同样地方式进行接收。
将每个面板测量得到的所述最优下行发送波束信息发送给基站。
因终端首先上报的是第一类属性信息，在得到最优下行发送波束信息后可以在随机接入过程中将最优下行发送波束信息进行上报，也可以在随机接入之后在进行最优下行发送波束信息的上报，还需要说明的是，当最优下行发送波 束信息在随机接入之后上报时，终端可以将该最优下行发送波束信息与第二类属性信息一同上报，也可以单独进行该最优下行发送波束信息的上报。
上述方式二在实际应用中的具体实现过程如图5所示：
步骤501，在随机接入过程中，基站接收终端的第一类属性信息，然后依该据第一类属性信息发送相应数目的下行Tx beam；
需要说明的是，当基站在随机接入过程中，先接收到UE的RA preamble，该信息中含有UE的第一类属性信息，然后在随后的RA response(应答)消息发射时，针对UE的panel所支持的beam数量，发送相应数目的下行Tx beam。
步骤502，终端接收下行Tx beam，并确定每个panel对应的最优Tx beam和Rx beam。
需要说明的是，终端利用多个panel上的模拟波束进行空间方向的轮流接收，搜索到每个panel对应的最优下行Tx beam和Rx beam。
步骤503，终端在上报第二类属性信息时，将最优下行Tx beam一同反馈给基站。
需要说明的是，UE的第二类属性信息是UE在发送RRC Connection Request时上报的。
步骤504，基站使用终端反馈的最优下行Tx beam，发送RRC Connection Setup给终端，完成随机接入，建立RRC连接。
需要说明的是，基站在进行数据传输时，使用UE各panel的最优下行Tx beam承载下行信道，UE则使用每个panel最优下行Rx beam进行数据接收。这里的数据传输所使用的beam，对于每个panel的每个极化方向阵列，可以使用不同的beam。而且，如果每个panel支持的频点不同，则需要使用各自的频点来发送beam上的数据。例如，UE有2个panel，每个panel上的阵列只有一个极化方向，则基站可以使用空间复用技术，发送2路并行数据流，每个数据流使用每个panel对应的最优beam承载，或者2路数据流是经过预编码后再使用每个panel对应的最优beam承载。UE则使用两个panel分别接收这2路数据流。
还需要说明的是，为了便于基站对最优下行发送波束的区分，终端发送给基站的最优下行发送波束信息通常需要包括：测量得到最优下行发送波束的面板的标识信息(可以为面板的ID)以及最优下行发送波束的标识信息(可以为 波束的ID)。
本公开的实施例，通过在随机接入时，将终端天线结构的设置参数发送给基站，此种方式不影响后续的信息发送过程，同时实现了网络侧根据天线阵列结构信息利用更多天线进行用户调度和数据传输时，提供给系统更高效的波束管理、更精准的波束对齐、更优化的多用户调度和多数据流传输。
如图6所示，为本公开一些实施例的终端信息上报方法的流程图。下面结合本图具体说明终端信息上报方法的实现过程。
本公开一些实施例提供一种终端信息上报方法，应用于一终端，包括：
步骤601，在建立与基站的RRC连接之后，接收基站发送的终端能力查询消息。
需要说明的是，基站在于终端建立RRC连接后，需要获知终端的能力信息，此时，基站需要向终端发送终端能力查询消息。
步骤602，根据所述终端能力查询消息，向基站反馈终端能力信息，其中所述终端能力信息包括终端的第一类属性信息和第二类属性信息或所述终端能力信息包括终端的第一类属性信息；其中，所述第一类属性信息包括终端天线结构的设置参数。
需要说明的是，因终端侧有两种能力信息进行反馈，即第一类属性信息(指的是终端天线结构的设置参数)和第二类属性信息(与背景技术中所提到的UE EUTRA capability所包含的参数相同)，在进行这两种能力信息发送时，终端可以将两种能力信息一同发送给基站，也可以分别进行这两种能力信息的发送。
本公开的实施例，实现的是将终端天线结构的设置参数在RRC连接建立之后发送给基站，然后基站再将终端所有的能力信息发送给MME。
需要说明的是，所述基带参数包括：终端支持的收发器单元个数；所述射频参数包括：面板个数、每个面板支持的频点信息、每个面板支持的波束个数和每个面板上的天线阵列极化方向的个数中的一个或者多个。所述反馈消息可以为随机接入前导消息(RA Preamble)，也可以为无线资源控制(RRC)连接请求消息。
需要说明的是，本公开的一些实施例中新增的终端天线结构的设置参数可以在UE EUTRA capability中新增信息元素(IE)实现，也可以在UE Category中新增参数选项实现。
还需要说明的是，新增IE可以是一个新IE，包括但不限于例如：UE天线结构信息(antenna structure information)，在该IE下可以包括以下参数：number of baseband unit(基带单元个数)、number of panel(面板个数)、number of array polarization direction in a panel(面板中天线阵列极化方向个数)、number of beam in a panel(面板中波束个数)等；或者也可以将上述各个参数都设置成一个IE。
还需要说明的是，所述UE Category中新增参数可以包括上述所列的各个参数。
为了使得基站能较好发送下行数据，所述终端需要向基站上报最优下行发送波束，本公开的一些实施例中采用方式三进行最优下行发送波束的上报。
方式三、
在步骤602之后，本公开的一些实施例的所述终端信息上报方法，还包括：
根据对基站依据所述设置参数发送的匹配波束的接收强度，确定每个面板测量得到的最优下行发送波束信息。
需要说明的是，因终端已经发送了自身的天线结构的设置参数，基站在发送波束时就可以按照终端的天线结构的设置方式进行发送，终端在接收时，也按照同样地方式进行接收。
将每个面板测量得到的所述最优下行发送波束信息发送给所述基站。
需要说明的是，因终端已经将能力信息上报给了基站，所以此处只需将测量得到的最优下行发送波束信息给基站即可，同时，为了便于基站对最优下行发送波束的区分，终端发送给基站的最优下行发送波束信息通常需要包括：测量得到最优下行发送波束的面板的标识信息以及最优下行发送波束的标识信息。
上述方式三在实际应用中的具体实现过程如图7所示：
步骤701，终端根据基站的请求，将包含终端天线结构的设置参数的终端能力信息发送给基站。
需要说明的是，在此步骤中，终端按照相关技术中的协议中的UE能力上报方式，在随机接入后，基站发送UE Capability Enquiry给UE，然后UE发送UE Capability Information给基站的过程，将UE能力信息上报给基站，其中UE能力信息中包含终端天线结构的设置参数。
步骤702，在beam训练过程中，终端依据基站发送的下行Tx beam，确定最优下行Tx beam。
需要说明的是，基站根据UE能力所支持的panel个数、beam个数等信息，发送相匹配数量的训练波束。且基站的Beam训练可以是周期性或者触发性的。当需要进行beam训练时(即到达了训练时刻，或者发生了触发事件)，如果UE有2个panel，每个panel最多支持4个beam。那么基站将下行Tx beam以每4个为一组，同时同频发送该组Tx beam，UE的每个panel将使用所支持的4个beam轮流搜索该组下行Tx beam。具体的波束的发送结构如图8所示；然后，基站再更换另外一组4个Tx beam同时发送给UE，UE的每个panel再次进行搜索。最终，UE比较每个下行Tx beam组中的搜索结果，从而得到每个panel的最优Tx beam和Rx beam。每个panel的最优beam可能相同或者不同。
如图9所示，基站发送波束的具体形式为：假设UE有2个panel，每个panel支持4个beam(图中以不同的填充进行beam的区分)，基站在每个beam训练时刻，发送4个beam，UE的每个panel都进行最优beam搜索。
步骤703，UE周期性或者非周期性地将每个panel对应的最优下行Tx beam反馈给基站。
需要说明的是，终端同时还需维护最优beam集合，所述集合中包含每个panel的最优下行Tx beam和Rx beam。
随后，基站在最优下行Tx beam，在进行控制信道或数据信道发送时，将数据承载到对应每个panel的最优下行Tx beam上。
需要说明的是，由于UE每个panel所支持的波束个数和频点可以不同，例如高频panel和低频panel，此时网络侧需要针对UE的每个panel进行特定数目的波束或者数据流传输，实现波束对齐或者多层数据传输。反之，对于上行链路也是同理，即UE利用关于新天线结构的参数等消息向网络侧发送特定数目的波束或者数据流，网络侧根据UE的panel个数、panel支持波束个数等信息，来使用特定数目的波束接收上行信号或信道。
还需要注意的是：在大规模的天线阵列结构中，UE的TxRU通常不是全向覆盖。比如对高频载波。每个panel可能每个极化方向连接到一个TxRU。此时UE能同时支持多个发射/接收波束，但不能是来自于同一个panel，除非是两个极化波束。当UE能力超过当前所接入网络的协议版本时(例如，Release 14 的UE接入到Release 13)，则要支持UE能力的降级处理，也就是说按照网络的能力来使用相对应协议版本的UE能力，而更高级的UE能力则不使用。
本公开的实施例，通过在RRC连接建立完成后，基站需要终端能力信息时，终端在发送终端天线结构的设置参数给基站，使得终端有针对性的发送终端天线结构的设置参数，避免了信息的无效传输；同时实现了网络侧根据天线阵列结构信息利用更多天线进行用户调度和数据传输时提供给系统更高效的波束管理、更精准的波束对齐、更优化的多用户调度和多数据流传输。
如图10所示，为本公开的一些实施例的终端的结构示意图，下面就该图并结合图11至图13对基于该终端信息上报方法的终端进行具体说明。
