Description

信道状态信息CQI上报方法及通信装置 技术领域
本申请实施例涉及通信技术领域，尤其涉及一种信息上报方法及装置。
背景技术
终端向网络设备反馈的信道状态信息(channel state information，CSI)是多个指示信息的总称，例如，指示信息可以为信道质量指示(channel quality indicator，CQI)、预编码矩阵指示(precoding matrix indicator，PMI)、秩指示(rank indication，RI)、层指示(layer indicator，LI)、CSI-参考信号资源指示(reference signal resource indicator，CRI)。终端上报的CSI中可以包括一种或多种指示信息，终端每次上报的CSI中包含的指示信息的数量不同，则CSI的载荷(payload)长度也不同。CSI的载荷长度也可以简称为CSI的长度。终端上报CSI可能会出现不同的上报类型，例如，不同的秩、或不同的码本类型配置、或不同的CSI-RS端口数。在不同的上报类型下，各个指示信息的长度不同，所以即使终端每次上报的CSI中包含的指示信息的数量相同，整个CSI的长度也不同。
网络设备接收到终端发送的CSI后，对CSI进行译码，若无法确定CSI的载荷长度，需要进行多次盲检，这样导致译码效率很低，浪费译码资源。
发明内容
本申请实施例提供一种信息上报方法，用以提供一种统一CSI的长度的解决方法，在尽量不影响编码性能的基础上，提高接收端的译码性能。
本申请实施例提供的具体技术方案如下：
第一方面，提供一种信息上报方法，该方法通过以下步骤实现：终端判断CSI的长度是否小于预设长度，在确定所述CSI的长度小于所述预设长度时，在所述CSI中添加填充比特，其中，添加填充比特后的CSI的长度与所述预定长度一致，所述终端发送添加填充比特后的CSI。通过按照预设长度在CSI的长度添加填充比特，使得添加填充比特之后的CSI的长度等于预设长度，这样无论终端实际要上报的CSI的长度为小于25的任何值，通过添加填充比特，都能使得最终上报的CSI的长度统一为25。网络设备通过获取预设长度，无需尝试每种CSI可能长度，因此减少了盲检次数，降低了译码时延和复杂度。
在一个可能的设计中，第一种情况下，所述终端针对宽带或部分频带进行测量，获得所述宽带或部分频带的第一测量结果，将所述第一测量结果作为所述CSI。这种情况下，终端上报的CSI是针对宽带或部分频带测量的信道状态，整个CSI作为整体进行上报。这样，对于上报整体CSI的方式，能够通过预设长度的设计，使得终端上 报的整体CSI的长度达到统一。
在一个可能的设计中，所述预设长度为大于或等于27的值；例如，一种可选的方式中，所述预设长度的值为27。这样，终端将各种配置条件下获得的不等长的CSI统一到27比特，网络设备接收到CSI后可以按照预设长度为27进行译码，而无需尝试每种CSI可能长度，因此减少了盲检次数，降低了译码时延和复杂度。
在一个可能的设计中，在第一种情况下，所述终端根据所述CSI的配置条件确定所述预设长度；其中，所述CSI的配置条件为码本类型或CSI-参考信号RS的端口数。这样能够考虑不同的配置条件下CSI中各种指示信息的最大长度，从而确定合理的预设长度。
在一个可能的设计中，在第一种情况下，若所述CSI的配置条件为CSI-RS的端口数，则：当所述CSI-RS的端口数为2时，所述预设长度为12；当所述CSI-RS的端口数为4时，所述预设长度为16；当所述CSI-RS的端口数为大于4的值时，所述预设长度为27。将所有情况按照CSI-RS的端口数分为三类，可以减少CSI-RS的端口数为2或4时添加填充比特的数量，提高信道编码性能。
在一个可能的设计中，在第一种情况下，若所述CSI的配置条件为CSI-RS的端口数，则：当所述CSI-RS的端口数为2时，所述预设长度为10；当所述CSI-RS的端口数为4时，所述预设长度为16；当所述CSI-RS的端口数为大于4的值时，所述预设长度为27。将所有情况按照CSI-RS的端口数分为三类，可以减少CSI-RS的端口数为2或4时添加填充比特的数量，提高信道编码性能。
在一个可能的设计中，在第一种情况下，若所述CSI的配置条件为CSI-RS的端口数，则：当所述CSI-RS的端口数为2或4时，所述预设长度为16；当所述CSI-RS的端口数为大于4的值时，所述预设长度为27。将所有情况按照CSI-RS的端口数分为两类，可以减少CSI-RS的端口数为2或4时的添加填充比特的数量，提高信道编码性能。
在一个可能的设计中，在第一种情况下，若所述CSI的配置条件为码本类型，则：当所述码本类型为第一类型-多面板TypeI-MultiPanel时，所述预设长度为25；当所述码本类型为第一类型-单面板TypeI-SinglePanel时，所述预设长度为27。将所有情况按照码本类型分为两类，可以减少码本类型为TypeI-SinglePanel时添加填充比特的数量，提高信道编码性能。
在一个可能的设计中，上述各个可能的设计中，在第一种情况下预设长度的实际值还可以是大于上述各个预设长度的值。
在一个可能的设计中，在第二种情况下，所述终端针对宽带和子带进行测量，获得所述宽带和子带的第二测量结果，所述第二测量结果包括第一部分和第二部分，将所述第一部分作为所述CSI。这种情况下，终端上报的CSI实际是针对宽带和子带测量的信道状态信息的第一部分(Part1)，终端还会上报整个信道状态信息的第二部分(Part2)。这里需要将Part1的长度统一，而Part2的长度可以通过对Part1的译码结果获得。对于上报Part1的方式，能够通过预设长度的设计，使得终端上报的Part1的长度达到统一。
在一个可能的设计中，在第二种情况下，所述预设长度为大于或等于50的值；例如，一种可选的方式中，所述预设长度的值为50。这样，终端将各种配置条件下获得的不等长的CSI统一到27比特，网络设备接收到CSI后可以按照预设长度为27进行译码，而无需尝试每种CSI可能长度，因此减少了盲检次数，降低了译码时延和复杂度。
在一个可能的设计中，在第二种情况下，终端根据所述CSI的配置条件确定所述预设长度；其中，所述CSI的的上报类型为以下至少一种：CSI-参考信号RS的端口数、码本类型和子带数量。这样能够考虑不同的配置条件下CSI中各种指示信息的最大长度，从而确定合理的预设长度。

具体实施方式
下面将结合附图，对本申请实施例进行详细描述。
本申请提供一种通信方法及装置，用于提供一种统一CSI的长度的实现方案，从而提高译码效率和性能。具体的，在不同的CSI的配置条件下，采取对CSI添加不同数量的填充比特，使得发送的CSI的长度保持一致，这样，能够保证填充比特的数量尽量少，以减少对信道编码性能的影响。其中，方法和装置是基于同一发明构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
首先对本申请实施例用到的部分用语和一些基础知识作解释说明，以便于本领域技术人员理解。
1)宽带(wideband)、部分频带(partial-band)、子带(subband)
宽带为系统带宽或载波带宽，是指系统使用的全部物理资源块(physical resource block，PRB)。
子带的带宽为K个连续的PRB，K的取值根据系统带宽的不同取值而不同。在5G系统中，具体如表1所示。
表1
系统带宽包含的PRB数 子带包含的PRB数
＜24 N/A(不涉及)
24～72 4,8
73～144 8,16
145～275 16，32
不同的系统带宽和子带带宽下，系统带宽包含的子带的数目也是不同的，系统带宽中包含的子带的数目最小为3、最大为18。例如，如表1所示，当系统带宽包含24个PRB，每个子带为8个PRB时，系统带宽中包括3个子带；当系统带宽包含72个PRB，每个子带为4个PRB时，系统带宽中包括18个子带；当系统带宽为144个PRB，每个子带为8个PRB时，系统带宽中也包括18个子带。
部分频带是指系统带宽内的一个或多个子带。
2)载荷长度
是指承载某种信息的载荷长度，例如，指承载CSI的载荷长度。本申请中，为方便叙述，将载荷长度也可以叙述为长度。例如，CSI的载荷长度称为CSI的长度。
3)CSI的上报方式
在5G系统中，终端可以针对宽带或部分频带测量CSI，也可以针对宽带和子带测量CSI。
携带CSI的上行控制信息(uplink control information，UCI)可以在物理上行链路控制(physical uplink control channel，PUCCH)上传输，也可以在物理上行共享信道(physical uplink shared channel，PUSCH)上传输。PUCCH按照其所占时域符号数又可分为短PUCCH和长PUCCH。其中，短PUCCH只用于宽带或部分频带的CSI上报。长PUCCH可以用于宽带或部分频带的CSI上报，也可以用于宽带和子带CSI的上报。
终端根据指示信息的格式指示(FormatIndicator)来确定上报宽带或部分频带的CSI，或者上报宽带和子带的CSI。例如，当指示信息的格式指示为PMI-FormatIndicator＝widebandPMI且CQI-FormatIndicator＝widebandCQI时，长PUCCH用于宽带或部分频带的CSI上报。其中widebandPM用于指示上报宽带或部分频带的PMI，widebandCQI用于指示上报宽带或部分频带的CQI。当指示信息的格式指示为PMI-FormatIndicator＝subbandPMI或CQI-FormatIndicator＝subbandCQI时，长PUCCH用于宽带和子带的CSI上报，其中，subbandPMI用于指示上报宽带和子带的PMI，subbandCQI用于指示上报宽带和子带的CQI。当长PUCCH用于宽带和子带的CSI上报时，CSI会被分成两个部分：第一部分(Part1)和第二部分(Part2)。其中Part1可以包括CRI、RI、第一个传输块的宽带CQI、子带差分CQI、宽带幅度系数非零数量的指示等部分；Part2可以包括第二个传输块的宽带CQI、LI、PMI等部分。PUSCH用于CSI上报时，CSI也会被分成两个部分：Part1和Part2。Part1可以包括CRI、RI、第一个传输块的宽带CQI、子带差分CQI、宽带幅度系数非零数量的指示、RSRP、差分RSRP等部分；Part2可以包括第二个传输块的宽带CQI、LI、PMI等部分。
其中，第一个传输块和第二个传输块是指通过多天线技术在多个层上发送的传输 块。当系统使用的传输层数为1～4时，只传输一个传输块；当系统使用的传输层数为5～8时，传输2个传输块，例如可以称为第一传输块和第二传输块，或者称为传输块1和传输块2。Part2中所包含的LI、PMI等指示信息的长度由Part1中指示信息确定，因此在接收端对Part1译码成功后，根据Part1内容的指示，可进行Part2的译码。Part1和Part2长度可以不同，Part1译码成功后，可以根据Part1内容的指示确定Part2的长度。
综上，CSI的上报方式可以包括两种。第一种方式为上报整个CSI；第二种方式为：在CSI分为两个部分时，分别上报Part1和Part2。
当上报整个CSI时，无论各部分指示信息的长度是多少，需要保证整个CSI的长度一致。当分别上报Part1和Part2时，由于Part2的长度可以根据Part1译码得到的内容指示来确定，所以终端需要保证Part1的长度一致，以实现接收端的成功接收和译码。
4)码本类型
在5G系统中，码本类型可以是第一类型-多面板TypeI-MultiPanel，或者第一类型-单面板TypeI-SinglePanel，或者第二类型TypeII，TypeII包括TypeII-端口选择PortSelection。
5)子带数量L
本申请以下描述中，子带数量均用L来表示。在5G系统中，根据协议的规定，L的取值范围为[3,18]，L的最小值为3，最大值为18。L的取值为正整数。
6)“或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。“或者”，描述关联对象的关联关系，标识可以存在两种关系，例如A或者B，可以表示：单独存在A，单独存在B两种情况。“多个”，是指两个或两个以上。“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。字符“/”一般表示前后关联对象是一种“或”的关系。
基于以上说明，下面将结合附图对本申请实施例提供的信息上报方法和装置做详细说明。
以下介绍一下本申请实施例适用的通信系统架构。
图1示出了本申请实施例提供的信息上报方法适用的一种可能的通信系统的架构，参阅图1所示，通信系统100中包括：网络设备101和一个或多个终端102。当通信系统100包括核心网时，网络设备101还可以与核心网相连。网络设备101可以通过核心网与IP网络103进行通信，例如，IP网络103可以是：因特网(internet)，私有的IP网，或其它数据网等。网络设备101为覆盖范围内的终端102提供服务。例如，参见图3所示，网络设备101为网络设备101覆盖范围内的一个或多个终端102提供无线接入。通信系统100还可以包括网络设备101’，网络设备之间的覆盖范围可以存在重叠的区域，例如网络设备101和网络设备101’。网络设备之间还可以互相通信，例如，网络设备101可以与网络设备101’之间进行通信。
网络设备101是本申请应用的通信系统中将终端102接入到无线网络的设备。网 络设备101为无线接入网(radio access network，RAN)中的节点，又可以称为基站，还可以称为RAN节点(或设备)。目前，一些网络设备101的举例为：gNB/NR-NB、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)，或5G通信系统或者未来可能的通信系统中的网络侧设备等。
终端102，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音或数据连通性的设备，也可以是物联网设备。例如，终端102包括具有无线连接功能的手持式设备、车载设备等。目前，终端102可以是：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备(例如智能手表、智能手环、计步器等)，车载设备(例如，汽车、自行车、电动车、飞机、船舶、火车、高铁等)、虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、智能家居设备(例如，冰箱、电视、空调、电表等)、智能机器人、车间设备、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端，或智慧家庭(smart home)中的无线终端、飞行设备(例如，智能机器人、热气球、无人机、飞机)等。
本申请中，终端102将CSI上报给网络设备101，网络设备101接收终端102上报的CSI。
图1所示的通信系统可以是第四代(4thgeneration，4G)通信系统、第五代(5th generation，5G)通信系统或未来的各种通信系统。
基于图1所示的通信系统架构，如图2所示，下面详细介绍一下本申请实施例提供的信息上报方法。该信息上报方法的执行主体可以是图1所示的通信系统中的终端102。
步骤201、终端判断CSI的长度是否小于预设长度。若是，则执行步骤202，否则执行步骤204。
该预设长度可以是网络设备通知的，或者该预设长度为协议中指定的。
可选的，在步骤201之前，终端还需要获取CSI。具体的，终端对宽带或部分频带进行测量，获得宽带或部分频带的第一测量结果，在这种情况下，步骤201中所述的CSI可以认为是第一测量结果。或者，终端若对宽带和子带进行测量，获得宽带和子带的第二测量结果，第二测量结果中包括Part1和Part2，在这种情况下，步骤201中所述的CSI可以认为是第二测量结果中的Part1。
步骤202、终端在确定CSI的长度小于预设长度时，在CSI中添加填充(padding)比特，其中，添加填充比特后的CSI的长度与预设长度一致。
填充比特可以固定为0，或固定为1。
步骤203、终端发送添加填充比特后的CSI。
实际应用中，终端可以采用任意编码方式对填充比特后的CSI进行编码，例如，可以采用极化码(Ploar码)的编码方式。将添加填充比特后的CSI的载荷输入Ploar码编码器进行编码，发送编码后的比特。
步骤204，终端在确定CSI的长度不小于预设长度时，不用在CSI中添加填充比特，直接发送CSI即可。
下面根据图2中各步骤所述的CSI的不同情况，分别对不同情况下的预设长度进行详细描述。
以下介绍第一种情况：上述步骤中的CSI为第一测量结果。
在第一种情况下，终端可以根据CSI的配置条件来确定预设长度。CSI的配置条件可以是秩的大小，或者码本类型(CodebookType)，或者CSI-RS的端口数，还可以是任意几项的结合。在CSI的配置条件不同时，CSI中的各个指示信息的长度可能也不同。
下面介绍在第一种情况下，根据码本类型确定预设长度的详细内容。
表2示出了在码本类型为TypeI-SinglePanel时，在不同秩和不同CSI-RS的端口数下各个指示信息的最大长度，以及当上报的CSI中包含所有指示信息时该CSI的最大长度。
表2
Figure PCTCN2019074539-appb-000001
Figure PCTCN2019074539-appb-000002
举例来说，根据表2可以看出，码本类型为TypeI-SinglePanel，CSI-RS端口数等于2时，CRI的最大长度为3bit，RI的最大长度为1bit，LI的最大长度为1bit，PMI的最大长度为3bit，CQI的最大长度为4bit。终端实际上报的CSI中可能包含上述部分类型的指示信息，也可能包含上述所有类型的指示信息。当终端上报的CSI中包含上述所有类型的指示信息时，CSI的最大可能的载荷长度为12bit。类似的表2中其它类型下CSI的最大可能的载荷长度依次为20、16、22、15、22、25。选取几个值中的最大值为25，可以得出，在码本类型为TypeI-SinglePanel时，CSI的最大可能的载荷长度为25。
当确定CSI的配置条件为码本类型，且码本类型为TypeI-SinglePanel时对应的预设长度为25。
表3示出了在码本类型为TypeI-MultiPanel时，在不同的秩下各个指示信息的最大长度，以及当上报的CSI中包含所有指示信息时该CSI的最大长度。
表3
Figure PCTCN2019074539-appb-000003
举例来说，根据表3可以看出，码本类型为TypeI-MultiPanel，秩等于1时，CRI的最大长度为3bit，RI的最大长度为2bit，LI的最大长度为0bit，PMI的最大长度为14bit，CQI的最大长度为4bit。终端实际上报的CSI中可能包含上述部分类型的指示信息，也可能包含上述所有类型的指示信息。当终端上报的CSI中包含上述所有类型的指示信息时，CSI的最大可能的载荷长度为23bit。类似的，表3中还示出了秩等于2或3或4时，CSI的最大可能的载荷长度为27。23和27中取最大值，可以得出，在码本类型为TypeI-MultiPanel时，CSI的最大可能的载荷长度为27。
当确定CSI的配置条件为码本类型且码本类型为TypeI-SinglePanel时对应的预设长度设为27。
综上，当确定CSI的配置条件为码本类型时，终端根据码本类型来确定预设长度，码本类型与预设长度的对应关系可以如表4所示。
表4
码本类型 预设长度(比特)
TypeI-SinglePanel 25
TypeI-MultiPanel 27
如表4所示，当码本类型为TypeI-SinglePanel时，预设长度为25。在步骤201中，终端判断CSI的长度小于25时，在CSI中添加填充比特，使得添加填充比特后的CSI的长度为25，发送长度为25的CSI。这样无论终端实际要上报的CSI的长度为小于25的任何值，通过添加填充比特，都能使得最终上报的CSI的长度统一为25。当码本类型为TypeI-MultiPanel，预设长度为27。在步骤201中，终端判断CSI的长度小于27时，在CSI中添加填充比特，使得添加填充比特后的CSI的长度为27，发送长度为27的CSI。这样无论终端实际要上报的CSI的长度为小于27的任何值，通过添加填充比特，都能使得最终上报的CSI的长度统一为27。
将所有情况按照两种码本类型进行划分，可以减少码本类型为Type1-SinglePanel下填充比特的数量，提高信道编码性能。
下面介绍一下在第一种情况下，当CSI的配置条件是CSI-RS的端口数时对应的预设长度。
CSI-RS的端口数可能为2、4、8……等值，在CSI-RS的端口数不同时，CSI中各个指示信息的最大长度也不同。如表5所示，将CSI-RS的端口数分为三种：CSI-RS的端口数为2；CSI-RS的端口数为4；CSI-RS的端口数为大于4的值。表5示出了在CSI-RS的端口数在这三种情况下各个指示信息的最大长度，以及当上报的CSI中包含所有指示信息时该CSI的最大长度(即CSI的最大可能的载荷长度)。
表5
Figure PCTCN2019074539-appb-000004
举例来说，从表5可以看出，CSI-RS的端口数为2时，CSI的最大可能的载荷长度为12bit，此时，CRI的长度为3bit，RI的长度为1bit，LI的长度为1bit，PMI的长度为3bit，CQI的长度为4bit。终端实际上报的CSI中可能包含上述部分类型的指示信息，也可能包含上述所有类型的指示信息。当终端上报的CSI中包含上述所有类型 的指示信息时，CSI的最大可能的载荷长度为12bit。
CSI-RS的端口数为4时，CSI的最大可能的载荷长度为16bit，此时，CRI的长度为3bit，RI的长度为2bit，LI的长度为1bit，PMI的长度为6bit，CQI的长度为4bit。当终端上报的CSI中包含上述所有类型的指示信息时，CSI的最大可能的载荷长度为16bit。
CSI-RS的端口数为大于4的值时，CSI的最大可能的载荷长度为27bit，此时，CRI的长度为3bit，RI的长度为2bit，LI的长度为2bit，PMI的长度为16bit，CQI的长度为4bit。当终端上报的CSI中包含上述所有类型的指示信息时，CSI的最大可能的载荷长度为27bit。
综上，当确定CSI的配置条件为CSI-RS的端口数时，终端根据CSI-RS的端口数来确定预设长度，CSI-RS的端口数与预设长度的对应关系可以如表6所示。

其中，CSI-RS的端口数为2，对应的预设长度为12bit，在步骤201中，终端判断CSI的长度小于12时，在CSI中添加填充比特，使得添加填充比特后的CSI的长度为12，发送长度为12的CSI。这样无论终端实际要上报的CSI的长度为小于12的任何值，通过添加填充比特，都能使得最终上报的CSI的长度统一为12；
CSI-RS的端口数为4，对应的预设长度为16bit，类似的，在步骤201中，终端判断CSI的长度小于16时，在CSI中添加填充比特，使得添加填充比特后的CSI的长度为16，发送长度为16的CSI。这样无论终端实际要上报的CSI的长度为小于16的任何值，通过添加填充比特，都能使得最终上报的CSI的长度统一为16；
CSI-RS的端口数为大于4的值，对应的预设长度为27bit。在步骤201中，终端判断CSI的长度小于27时，在CSI中添加填充比特，使得添加填充比特后的CSI的长度为27，发送长度为27的CSI。这样无论终端实际要上报的CSI的长度为小于27的任何值，通过添加填充比特，都能使得最终上报的CSI的长度统一为27。
将所有情况按照CSI-RS的端口数进行划分，可以减少CSI-RS的端口数为2或4时填充比特的数量，提高信道编码性能。
下面介绍一下在第一种情况下，当CSI的配置条件是CSI-RS的端口数时对应的另一种预设长度。
CSI-RS的端口数可能为2、4、8……等值，在CSI-RS的端口数不同时，CSI中各个指示信息的最大长度也不同。如表5所示，将CSI-RS的端口数分为三种：CSI-RS的端口数为2；CSI-RS的端口数为4；CSI-RS的端口数为大于4的值。表A示出了在CSI-RS的端口数在这三种情况下各个指示信息的最大长度，以及当上报的CSI中 包含所有指示信息时该CSI的最大长度(即CSI的最大可能的载荷长度)。

举例来说，从表A可以看出，CSI-RS的端口数为2时，CSI的最大可能的载荷长度为10bit，此时，CRI的长度为3bit，RI的长度为1bit，LI的长度为1bit，PMI的长度为1bit，CQI的长度为4bit。终端实际上报的CSI中可能包含上述部分类型的指示信息，也可能包含上述所有类型的指示信息。当终端上报的CSI中包含上述所有类型的指示信息时，CSI的最大可能的载荷长度为12bit。
CSI-RS的端口数为4时，CSI的最大可能的载荷长度为16bit，此时，CRI的长度为3bit，RI的长度为2bit，LI的长度为1bit，PMI的长度为6bit，CQI的长度为4bit。当终端上报的CSI中包含上述所有类型的指示信息时，CSI的最大可能的载荷长度为16bit。
CSI-RS的端口数为大于4的值时，CSI的最大可能的载荷长度为27bit，此时，CRI的长度为3bit，RI的长度为2bit，LI的长度为2bit，PMI的长度为16bit，CQI的长度为4bit。当终端上报的CSI中包含上述所有类型的指示信息时，CSI的最大可能的载荷长度为27bit。
综上，当确定CSI的配置条件为CSI-RS的端口数时，终端根据CSI-RS的端口数来确定预设长度，CSI-RS的端口数与预设长度的对应关系可以如表B所示。

CSI-RS的端口数为4，对应的预设长度为16bit，类似的，在步骤201中，终端判断CSI的长度小于16时，在CSI中添加填充比特，使得添加填充比特后的CSI的长度为16，发送长度为16的CSI。这样无论终端实际要上报的CSI的长度为小于16的任何值，通过添加填充比特，都能使得最终上报的CSI的长度统一为16；
CSI-RS的端口数为大于4的值，对应的预设长度为27bit。在步骤201中，终端判断CSI的长度小于27时，在CSI中添加填充比特，使得添加填充比特后的CSI的长度为27，发送长度为27的CSI。这样无论终端实际要上报的CSI的长度为小于27的任何值，通过添加填充比特，都能使得最终上报的CSI的长度统一为27。
将所有情况按照CSI-RS的端口数进行划分，可以减少CSI-RS的端口数为2或4时填充比特的数量，提高信道编码性能。
基于表5或表6，在另一种可能的实现方式中，如表7所示，CSI-RS的端口数为2或4时，对应的预设长度均为16；CSI-RS的端口数为大于4的值，对应的预设长度为27bit。

>4 27
将所有情况按照CSI-RS的端口数进行划分，可以减少CSI-RS的端口数为2或4时填充比特的数量，提高信道编码性能。
通过表4和表6(或表7)可以看出，在第一种情况下，在考虑码本类型、秩的大小、CSI-RS的端口数等多个配置条件时，CSI中包含所有指示信息都上报时最大可能的载荷长度为27。基于此，在另一种可能的设计中，将预设长度设为M，M是大于或等于27的数，在步骤201中，终端判断CSI的长度小于M时，在CSI中添加填充比特，使得添加填充比特后的CSI的长度为M，发送长度为M的CSI。这样无论终端实际要上报的CSI的长度为小于M的任何值，通过添加填充比特，都能使得最终上报的CSI的长度统一为M。为减少冗余比特，M可以固定为27。
第一种情况下各种CSI的配置条件对应的预设长度介绍完毕。另外，终端在CSI中添加填充比特的位置可以是任意两个指示信息之间。在第一种情况下，CSI包含的指示信息可以包括：CRI、RI、LI、PME、CQI。可选的，终端在CRI和RI之后，PMI和CQI之前添加填充比特。
以下介绍第二种情况：上述步骤中的CSI为Part1。
在第二种情况下，终端可以根据CSI的配置条件来确定预设长度。CSI的配置条件可以是子带数量，或者码本类型，或者CSI-RS的端口数，还可以是任意几项的结合。在CSI的配置条件不同时，CSI中的各个指示信息的长度可能也不同。CSI中包含的指示信息可以包括但不限于以下一种或多种：CRI、RI、第一个传输块的宽带CQI、 子带差分CQI、宽带幅度系数非零数量指示。
1、根据子带数量来确定预设长度。
子带数量可以用L来表示，L的取值范围为[3,18]，即，L的取值最小为3，最大为18，L为正整数。
不同子带数量下，子带差分CQI的长度不同，因此会影响Part1的长度不同。相同子带数量条件下，RI也会因为配置不同而长度不同。最大可能的Part1的长度在码本类型为TypeII(包括TypeII-PortSelection)，CSI-RS端口数大于4时得到。
表8示出了在码本类型为TypeII(包括TypeII-PortSelection)，CSI-RS端口数大于4时得到的不同子带数量下各指示信息的最大长度，以及当上报的Part1中包含所有指示信息时该CSI的最大长度。
表8
Figure PCTCN2019074539-appb-000006
从表8可以看出，子带数量为3时，CRI的最大长度为3bit，RI的最大长度为1，第一个传输块的宽带CQI的最大长度为4，子带差分CQI的最大长度为6，宽带幅度系数非零数量指示的最大长度为6，当终端上报的CSI中包含上述所有类型的指示信息时，CSI的最大可能的载荷长度为20bit。类似的，当子带数量分别为4、5、6、……、18时，CSI的最大可能的载荷长度依次为22、24、26、……50。
综上，当根据子带数量来确定预设长度时，子带数量与预设长度的对应关系可以如表9所示。
表9
Figure PCTCN2019074539-appb-000007
预设长度与子带数量L之间的关系为：预设长度为(14+2*L)，其中，L取值范围为[3,18]。
将所有情况按照子带数量进行划分，可以减少子带数量较少时的填充比特的数量，提升信道编码的性能。
2、根据CSI-RS的端口数来确定预设长度。
CSI-RS的端口数分为两类：CSI-RS的端口数为4；CSI-RS的端口数为大于4的值。CSI-RS的端口数在每一种取值情况下，各个指示信息的最大长度会根据码本类型等配置参数的不同而不同。
表10示出了不同CSI-RS的端口数下各个指示信息的最大长度，以及当上报的Part1中包含所有指示信息时该CSI的最大长度。
表10
Figure PCTCN2019074539-appb-000008
在表10中，L为子带数量。根据协议中规定的L的取值，L的最大值为18。当L取值为18时，表10中最后一列表示的CSI的最大可能的载荷长度为最大值。具体地，如表11所示，当CSI-RS的端口数为4时，预设长度为(12+2*18)＝48；当CSI-RS的端口数为大于4的值时，预设长度为(14+2*18)＝50。
表11

>4 50
将所有情况按照CSI-RS的端口数进行划分，可以减少CSI-RS的端口数为4时填充比特的数量，提高信道编码性能。
3、根据码本类型来确定预设长度。
如术语解释中所述，三种可能的码本类型为：TypeI-SinglePanel，TypeI-MultiPanel，TypeII。表12示出了分别在每种码本类型下，在考虑到秩的大小、CSI-RS的端口数等多个配置条件时，各种指示信息的最大长度、以及CSI中包含所有指示信息都上报时最大可能的载荷长度。
表12
Figure PCTCN2019074539-appb-000009
Figure PCTCN2019074539-appb-000010
在表12中，L为子带数量。根据协议中规定的L的取值，L的最大值为18。当L取值为18时，表12中最后一列表示的CSI的最大可能的载荷长度取最大值。具体地，如表13所示，当码本类型为TypeI-SinglePanel时，预设长度为(10+2*18)＝46；当码本类型为TypeI-MultiPanel时，预设长度为(9+2*18)＝45；当码本类型为TypeII时，预设长度为(14+2*18)＝50。
表13
Figure PCTCN2019074539-appb-000011
将所有情况按照两种码本类型进行划分，可以减少码本类型为Type1-SinglePanel下填充比特的数量，提高信道编码性能。
4、根据子带数量和码本类型来确定预设长度。
具体的，可以先按照码本类型，确定在每种码本类型下，考虑到各种不同的配置条件下CSI最大可能的载荷长度。在每种码本类型下，再根据子带数量的不同划分为多个子类型，得到每种码本类型下不同的子带数量对应的预设长度。
如表14中所示，分别列出了：当码本类型为TypeI-SinglePanel时，子带数量在取值为3～18时分别对应的预设长度；当码本类型为TypeI-MultiPanel时，子带数量在取值为3～18时分别对应的预设长度；当码本类型为TypeII时，子带数量在取值为3～18时分别对应的预设长度。
表14

Figure PCTCN2019074539-appb-000013
Figure PCTCN2019074539-appb-000014
当然，也可以先按照子带数量，确定在每种子带数量下，考虑到各种不同的配置条件下CSI最大可能的载荷长度。在每种子带数量下，再根据码本类型的不同划分为多个子类型，得到每种子带数量下不同的码本类型对应的预设长度。这种确定方式所得结果的表格表现形式与表14不同，但是内容相符，即子带数量和码本类型对应的预设长度是一致的。
5、根据子带数量和CSI-RS的端口数来确定预设长度。
具体的，可以先按照CSI-RS的端口数，确定在每种CSI-RS的端口数下，考虑到各种不同的配置条件下CSI最大可能的载荷长度。在每种CSI-RS的端口数下，再根据子带数量的不同划分为多个子类型，得到每种CSI-RS的端口数下不同的子带数量对应的预设长度。
如表15所示，分别列出了：当CSI-RS的端口数为4时，子带数量在取值为3～18时分别对应的预设长度；当CSI-RS的端口数为大于4的值时，子带数量在取值为3～18时分别对应的预设长度。
表15
Figure PCTCN2019074539-appb-000015
Figure PCTCN2019074539-appb-000016
当然，也可以先按照子带数量，确定在每种子带数量下，考虑到各种不同的配置条件下CSI最大可能的载荷长度。在每种子带数量下，再根据CSI-RS的端口数的不同划分为多个子类型，得到每种子带数量下不同的CSI-RS的端口数对应的预设长度。这种确定方式所得结果的表格表现形式与表14不同，但是内容相符，即子带数量和CSI-RS的端口数对应的预设长度是一致的。
通过表9、表11、表13、表14和表15可以看出，在第二种情况下，在考虑码本类型、秩的大小、CSI-RS的端口数等多个配置条件时，CSI中包含所有指示信息都上报时最大可能的载荷长度为(14+2*L)，L的最大取值为18，因此预设长度的最大值为(14+2*18)＝50。基于此，在另一种可能的设计中，在第二种情况下，将预设长度设为N，N是大于或等于50的数，在步骤201中，终端判断CSI的长度小于N时， 在CSI中添加填充比特，使得添加填充比特后的CSI的长度为N，发送长度为N的CSI。通过添加填充比特，使得最终上报的CSI的长度统一为N。为减少冗余比特，N可以固定为50。
第二种情况下各种CSI的配置条件对应的预设长度介绍完毕。另外，终端在CSI中添加填充比特的位置可以是任意两个指示信息之间。在第二种情况下，CSI包含的指示信息可以包括：CRI、RI、第一传输块的宽带CQI(即传输块1的宽带CQI)、子带差分CQI和宽带幅度系数非零数量指示。如图3所示，一种可能的实现方式中，终端在所有指示信息之后添加填充比特。如图4所示，另一种可能的实现方式中，终端在CRI和RI之后，在传输块1的宽带CQI之前添加填充比特。如图5所示，若采用Polar码编码方式对添加填充比特后的CSI进行编码，则另一种可能的实现方式中，终端在可靠度最低的位置添加填充比特，如在CRI和RI之后，可靠度最低的位置上添加填充比特，填充比特可以作为冻结比特。网络设备作为接收端，在接收到CSI数据后，先译码得到CRI和RI，除CRI和RI外其他指示信息的长度可以通过信令进行计算，填充比特的长度可以通过预设长度减去CRI和RI的长度，再减去CRI和RI外其他指示信息长度得到。填充比特作为冻结比特，还能够提升Polar码译码性能。
至此，第一种情况和第二种情况下不同的CSI的配置条件对应的预设长度介绍完毕。以下对于第一种情况和第二情况综合做几点说明。
需要说明的是，上述任意表中所示的预设长度的值为一种举例，实际应用中的预设长度可以大于表中所示的预设长度的值，但是预设长度的值越大，填充比特的数量越多，增加更多的冗余比特，为了降低对信道编码性能的影响，可以选择如上述各表中所示的预设长度的值。
终端确定上报CSI的一些配置条件，具体是哪种情况以及哪种CSI的配置条件，根据配置条件确定对应的预设长度。例如是第一种情况还是第二情况。在第一种情况下具体为哪种CSI的配置条件，例如CSI的配置条件为CSI-RS的端口数，则需要确定在第一种情况下，不同CSI-RS的端口数对应的预设长度。本申请中设计的预设长度对所有情况进行划分，可以保证添加填充比特的数量尽量少，以减少对信道编码性能的影响。
终端在获得CSI后，判断CSI的长度小于预设长度时，在CSI中添加填充比特，使得添加填充比特后的CSI的长度为预设长度。无论终端实际要上报的CSI的长度为小于预设长度的任何值，通过添加填充比特，都能使得最终上报的CSI的长度统一为预设长度。
网络设备为接收端，网络设备在接收到CSI后，根据已知的CSI的配置条件等配置条件，按照预设长度和填充比特的位置对CSI进行译码。网络设备通过获取预设长度，无需尝试每种CSI可能长度，因此减少了盲检次数，降低了译码时延和复杂度。
