Description

信息传输方法、装置及系统
本申请要求于2021年04月06日提交国家知识产权局、申请号为202110369481.3、申请名称为“信息传输方法、装置及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及信息传输方法、装置及系统。
背景技术
通常，终端设备可以采用多种物理上行控制信道(physical uplink control channel，PUCCH)格式(PUCCH format)传输上行控制信息(uplink control information，UCI)。其中，UCI可以包括混合自动重传请求确认(hybrid automatic repeat request acknowledgement，HARQ-ACK)信息、信道状态信息(channel-state information，CSI)、或调度请求(scheduling request，SR)中的一种或多种。
目前，新空口(new radio，NR)标准定义了五种PUCCH格式，分别为PUCCH format0/1/2/3/4。其中，NR标准版本(Release，R)15和R16中对于PUCCH format 4(下文简称PF4)做出如下规定：在时域上占用4～14个符号，频域占用1个资源块(resource block，RB)；承载大于2比特(bit)的信息；在UCI包括CSI的情况下，UCI比特数和循环冗余校验码(cyclic redundancy check，CRC)比特数之和不超过115比特。
基于上述规定，由于PF4在频域占用1个RB，在一些场景下，会对功率谱密度(power spectral density，PSD)进行约束，限制了终端设备的发射功率，从而导致PUCCH的覆盖范围受限。
发明内容
本申请提供一种信息传输方法、装置及系统，能够提高UCI的覆盖范围，从而提高通信效率。
为达到上述目的，本申请提供如下技术方案：
第一方面，提供了一种信息传输方法，该方法可以由终端设备执行，也可以由终端设备的部件，例如终端设备的处理器、芯片、或芯片系统等执行，还可以由能实现全部或部分终端设备功能的逻辑模块或软件实现。该方法包括：确定上行控制信息UCI，并在N个频域资源单元上向网络设备发送UCI，N为大于1的正整数。
基于该方案，本申请采用N个频域资源单元发送UCI，一方面，在功率谱密度确定的情况下，频域资源单元的数量越多，发送功率可以越大，由于本申请发送UCI的频域资源单元增加，从而可以增加终端设备的发射功率，进而提高UCI的覆盖范围；另一方面，由于本申请发送UCI的频域资源单元增加，在每个频域资源单元承载的UCI比特数存在阈值的情况下，通过N个频域资源单元可以承载更多的UCI比特，在CSI的数据量较大时，可以提高CSI的反馈效率，进而提高通信效率。再一方面，在UCI比特数较小时，可以在N个频域资源单元上进行速率匹配，以降低码率，从而提高传输可靠性。
结合第一方面，在第一方面的某些实施方式中，UCI包括N个UCI子段，N个UCI子段中不同的UCI子段由N个频域资源单元中不同的频域资源单元承载。
基于该实施方式，一方面，将UCI分为N个UCI子段在N个频域资源单元上传输，使得每个频域资源单元上传输的UCI比特减少，从而可以增加冗余比特，即降低码率， 提高传输可靠性。另一方面，N个频域资源单元相比于一个频域资源单元可以传输更多的UCI信息，在UCI包括CSI，且CSI的数据量较大的情况下，可以通过一次发送将CSI的全部数据量反馈给网络设备，从而提高CIS反馈的及时性，进而提高通信效率；再一方面，将UCI分为N个UCI子段，在该N个UCI子段的部分UCI子段传输成功的情况下，网络设备可以获得部分UCI，终端设备可以重发传输失败的部分，而无需重发全部UCI，从而可以降低资源开销。
结合第一方面，在第一方面的某些实施方式中，UCI子段的比特数和UCI子段对应的循环冗余校验码CRC的比特数之和小于或等于第一阈值，第一阈值为频域资源单元能够承载的最大比特数。基于该实施方式，能够使得频域资源单元上承载的比特不超过其最大承载能力，从而减少出错，提高传输效率。

具体实施方式
为了方便理解本申请实施例的技术方案，首先给出本申请相关技术的简要介绍如下。
1、UCI物理层处理流程：
示例性的，如图1a所示，为终端设备的UCI物理层处理流程，主要包括以下步骤：
S101a、分割与CRC插入。
其中，对UCI进行分割与CRC插入后得到一个或多个带差错保护的码块。
S102a、信道编码。
其中，信道编码的单位为码块，其中，“码块”也可以称为“编码块”。信道编码可以使码流的频谱特性适应信道的频谱特性，从而使传输过程中能量损失最小，提高信号能量与噪声能量的比例，减小发生差错的可能性，增加通信的可靠性。
可以理解的，在该步骤S102a中，分别对步骤S101a得到的一个或多个码块进行信道编码。信道编码时采用的码率可以理解为基准码率。
S103a、速率匹配。
其中，速率匹配的单位为码块。速率匹配可以指信道上的比特被重发(repeated)或者被打孔(punctured)，以匹配物理信道的承载能力，信道映射时达到传输格式所要求的比特速率。
可以理解的，在该步骤S103a中，分别对步骤S102a得到的信道编码后的码块进行速率匹配。
S104a、码块级联。
其中，码块级联可以指对步骤S103a中各个码块进行速率匹配后的结果进行合并。
S105a、调制。
通常，调制方式可以包括二进制相移键控(binary phase shift keying，BPSK)和正交相移键控(quadrature phase shift keying，QPSK)调制。此外，在一些场景下，调制方式还可以为正交幅度调制(quadrature amplitude modulation，QAM)，进一步的，QAM调制可以按照调制阶数的不同分为16QAM、64QAM、256QAM等。
可以理解的是，对速率匹配后的结果进行调整后可以得到调制符号。之后，可以将得到的调制符号映射至传输资源(例如PUCCH)，以便最终生成信号通过天线发送。
示例性的，如图1b所示，为网络设备的UCI物理层处理流程，网络设备对UCI的物理层处理过程为终端设备的逆过程，主要包括以下步骤：
S101b、解调制。
网络设备通过天线接收网络设备发送的信号后，对该信号进行解调制。可以理解的，解调制是调制的逆过程，网络设备使用的解调制方式与终端设备使用的调制方式相对应。例如，终端设备采用QPSK调制，则网络设备采用QPSK相应的解调方式解调。
S102b、解码块级联。
网络设备通过解码块级联(或者说解级联)可以将解调制后的比特分割为一份或多份。
S103b、解速率匹配。
可以理解的，解速率匹配是速率匹配的逆过程，终端设备进行速率匹配时的相关参数可以是网络设备配置的或者协议规定的，从而网络设备能够获知解速率匹配的方式。
S104b、信道译码。
可以理解的，信道译码是信道编码的逆过程，终端设备进行信道编码的方式可以是网络设备配置的或者协议规定的，从而网络设备能够获知信道译码的方式。
S105b、解码块分割与去CRC。
可以理解的是，该步骤S105b完成后，网络设备的物理层即获取到了UCI比特。之后，网络设备的物理层可以向上层(例如媒介接入控制(medium access control，MAC)层层)发送该UCI比特，以使上层对UCI比特进行处理。
如上所述，在NR标准R15和R16中，一方面，PUCCH format 4在频域占用1个RB。共享频段(例如52.6GHz-71GHz)中信号的发送存在法规约束，例如法规对PSD和最大发射功率进行了约束，若在共享频段中继续沿用R15和R16中的PUCCH format4,法规的约束可能使终端设备在PUCCH上发送UCI的功率受限，导致UCI的覆盖范围受限。共享频段可以被称为非授权频段。在终端设备距离网络设备较远的情况下，可能导致UCI无法被网络设备成功接收的问题，从而可能导致资源请求(SR)无法被及时处理、下行数据接收反馈(HARQ-ACK信息)不及时、CSI反馈不及时，进而造成资源浪费或降低通信效率。
另一方面，NR标准R15和R16中定义的PUCCH format 4对最大比特数存在约束，无法传输大于该约束的比特。在终端设备待上报的CSI的数据量较大时，CSI将被分段处理并分多次传输，可能导致CSI反馈不及时或不全面，影响系统的传输效率。

其中，存储器302用于存储执行本申请方案的计算机执行指令，并由处理器301来控制执行。具体的，处理器301用于执行存储器302中存储的计算机执行指令，从而实 现本申请实施例中所述的方法。

需要说明的是，本申请下述实施例中各个设备之间的消息名字或消息中各参数的名字或信息的名字等只是一个示例，具体实现中也可以是其他的名字，本申请实施例对此不作具体限定。
如图4所示，为本申请实施例提供的一种信息传输方法，该信息传输方法包括如下步骤：
S401、终端设备确定UCI。
在一些实施例中，UCI可以用于实现以下一项或多项功能：用于反馈下行数据是否接收成功、用于请求调度传输资源、或用于反馈信道状态。例如，UCI可以包括HARQ-ACK信息、SR、CSI中的一项或多项。
在一些实施例中，终端设备确定UCI也可以理解为终端设备生成UCI，两者可以相互替换，本申请对此不作具体限定。
在一些实施例中，步骤S401中终端设备确定的该UCI以比特形式表示，或者说，该UCI包括若干个比特，因此，该UCI也可以称为UCI比特。本申请以S401中终端设备确定的该UCI的比特数为A，或者说，UCI比特的数量为A为例进行说明，A为正整数。
在一些实施例中，该UCI的比特数A小于或等于PUCCH资源上能够传输的最大UCI比特数T，或者说，PUCCH资源上传输的UCI比特数的最大阈值为T。从而，如图5所示，在该步骤S401之前，本申请提供的信息传输方法还可以包括：终端设备确定最大UCI比特数T。
作为一种示例，该最大UCI比特数T可以是由网络设备配置的。例如，网络设备可以向终端设备发送第一配置信息用于配置PUCCH资源上能够传输的最大UCI比特数T，该第一配置信息可以携带在RRC消息中。该情况下，终端设备确定最大UCI比特数T，可以为：终端设备接收网络设备的第一配置信息，根据该第一配置信息确定最大UCI比特数T。
作为另一种示例，该最大UCI比特数T可以是协议约定的。该情况下，最大UCI比特数T可以是终端设备出厂时存储在终端设备中的，终端设备确定最大UCI比特数T以理解为：终端设备读取其存储的最大UCI比特数T。
S402、终端设备在N个频域资源单元上向网络设备发送UCI。相应的，网络设备接收来自终端设备的UCI。
其中，关于N个取值：
在一些实施例中，频域资源单元的数量N的取值可以是网络设备指示的。例如，网络设备向终端设备发送第三指示信息，该第三指示信息用于指示N的取值。相应的，终端设备收到该第三指示信息后，可以根据该第三指示信息确定N。
需要说明的是，本申请提供的信息传输方法还涉及“第一指示信息”和“第二指示信息”，将在后续实施例中对第一指示信息和第二指示信息进行说明，在此不予赘述。
在另一些实施例中，频域资源的数量N的取值可以是预设值。例如，该预设值可以是协议预定义的。
在一些实施例中，N的取值满足：
Figure PCTCN2022085181-appb-000009
其中，α 2、α 3、α 5为非负正数。
在一些实施例中，本申请中的频域资源单元为频域资源的单位，包括一个或多个最小粒度的频域资源。例如，在正交频分复用(orthogonal frequency division multiplexing，OFDM)系统中最小粒度的频域资源为子载波，从而，本申请中的频域资源单元可以包括一个或多个子载波，例如，本申请中的频域资源单元可以为RB，示例 性的包括12个子载波。随着通信系统的演进，本申请中的一个RB包括的子载波的数量也可以是其他值。
在一些实施例中，该N个频域资源单元可以是频域上连续的N个频域资源单元，例如为N个连续的RB，或者说，为N个连续的物理资源块(physical resource block，PRB)。
在一些实施例中，该N个频域资源单元在频域上也可以是非连续的，例如，该N个频域资源单元中任意两个相邻的频域资源单元的索引之差为第一数值。或者，该N个频域资源单元中的N1个频域资源单元在频域上是连续的，剩余N2个频域资源单元在频域上是非连续的，N为N1与N2之和，本申请对此不作具体限定。
在一些实施例中，终端设备采用第一PUCCH格式向网络设备发送UCI。该第一PUCCH格式可以是步骤S402之前终端设备确定的。从而，如图5所示，在该步骤S402之前，本申请提供的信息传输方法还包括：终端设备确定采用第一PUCCH格式进行UCI传输。作为一种示例，该第一PUCCH格式为PUCCH格式4。
作为一种示例，网络设备可以向终端设备发送第二配置信息，该第二配置信息用于配置第一PUCCH格式，例如，配置第一PUCCH格式对应的时域资源的位置、频域资源的位置、调制方式等。该情况下，终端设备确定采用第一PUCCH格式进行UCI传输，可以包括：终端设备接收来自网络设备的第二配置信息，根据该第二配置信息确定采用第一PUCCH格式进行UCI传输。
在一些实施例中，上述N个频域资源单元为该第一PUCCH格式占用的频域资源单元。
基于该方案，本申请采用N个频域资源单元发送UCI，一方面，在功率谱密度确定的情况下，频域资源单元的数量越多，发送功率可以越大，由于本申请发送UCI的频域资源单元增加，从而可以增加终端设备的发射功率，进而提高UCI的覆盖范围；另一方面，由于本申请发送UCI的频域资源单元增加，在每个频域资源单元承载的UCI比特数存在阈值的情况下，通过N个频域资源单元可以承载更多的UCI比特，在CSI的数据量较大时，可以提高CSI的反馈效率，进而提高通信效率。再一方面，在UCI比特数较小时，可以在N个频域资源单元上进行速率匹配，以降低码率，从而提高传输可靠性。
下面，对UCI在N个频域资源单元上的具体发送方法进行说明。示例性的，可以包括如下五种方式。
方式一：
终端设备将UCI分段后发送。
在一些实施例中，终端设备可以将UCI分为N个UCI子段，也就是说，该UCI包括N个UCI子段。其中，该N个UCI子段中的不同UCI子段由N个频域资源单元中不同的频域资源单元承载。或者说，该N个UCI子段中的每个UCI子段分别对应一个频域资源单元，不同UCI子段对应不同的频域资源单元。
在一些实施例中，本申请中的UCI子段也可以称为UCI子信息，两者可以相互替换，本申请对此不作具体限定。
在一些实施例中，该N个UCI子段中可以存在至少两个UCI子段的比特数不同。或者，在UCI的比特数A可以整除N的情况下，每个UCI子段的比特数可以相同，即均为A/N。
在一些实施例中，UCI的比特数A不能整除N的情况下，该N个UCI子段中的N-1个UCI子段的比特数可以为：
Figure PCTCN2022085181-appb-000010
另外一个UCI子段的比特数可以为：
Figure PCTCN2022085181-appb-000011
其中，
Figure PCTCN2022085181-appb-000012
表示向上取整。当然，式中的向上取整也可以替换为向下取整或四舍五入取整，本申请对此不作具体限定。
作为一种示例，比特数为
Figure PCTCN2022085181-appb-000013
的N-1个UCI子段可以是N个UCI子段中的前N-1个UCI子段，或者是后N-1个UCI子段，或者是任意的N-1个UCI子段，本申请对此不作具体限定。
作为一种实现方式，UCI子段的比特数和该UCI子段对应的CRC的比特数之和小于或等于第一阈值Q，该第一阈值Q为一个频域资源单元能够承载的最大比特数。
示例性的，该第一阈值可以是网络设备配置的，或者，可以是协议规定的，本申请对此不作具体限定。
在一些实施例中，如图6a所示，终端设备在N个频域资源单元上发送UCI，可以包括：
S601a、对N个UCI子段进行物理层处理，得到N个第一调制符号。
作为一种实现方式，终端设备对该N个UCI子段分别进行物理层处理，得到N个第一调制符号，该第一调制符号也可以理解为UCI子段对应的调制符号。也就是说，终端设备对第i个UCI子段进行物理层处理，得到一个第一调制符号，i＝1,2,...,N。
在一些实施例中，该物理层处理包括速率匹配，该速率匹配基于一个频域资源单元。或者说，该速率匹配以一个频域资源单元进行。或者说，该速率匹配用于匹配一个频域资源单元的承载能力。
以速率匹配的输入比特长度是M为例，确定速率匹配后的输出比特序列长度E后，即可以进行速率匹配。其中，E＝f(E tot)，也就是说，E是基于E tot的函数，或者说，E的取值与E tot相关，或者说，E的取值是根据E tot确定的。
作为一种示例，在终端设备基于一个频域资源单元进行速率匹配时，若调制方式为QPSK，则：
Figure PCTCN2022085181-appb-000014
若调制方式为π/2 BPSK，则：
Figure PCTCN2022085181-appb-000015
其中，
Figure PCTCN2022085181-appb-000016
为第一PUCCH格式对应的扩展因子；
Figure PCTCN2022085181-appb-000017
为第一PUCCH格式对应的时间单元的数量；a和b为正数，例如，a等于14，b等于12。
其中，第一PUCCH格式对应的扩展因子用于频域扩频，能够对抗频率选择性衰落。示例性的，该扩展因子的取值可以为2或4。
示例性地，本申请的时间单元可以为符号、时隙、子帧、或帧等。
在另一些实施例中，该物理层处理除速率匹配外，还可以包括以下一项或多项：码块分割与CRC插入、信道编码、码块级联、或调制。示例性的，在物理层处理包括上述列举的全部操作的情况下，如图7所示，为各个操作的执行流程，即对UCI子段进行 码块分割与CRC插入后，进行信道编码，再对信道编码后的结果进行速率匹配，之后对速率匹配后的结果进行码块级联，最后进行调制。
S602a、将N个第一调制符号映射至N个频域资源单元。
在一些实施例中，将N个第一调制符号映射至N个频域资源单元，可以包括：将一个第一调制符号映射至一个频域资源单元，不同频域资源单元上映射的第一调制符号不同。示例性的，终端设备可以将第i个UCI对应的第一调制符号，映射至第i个频域资源单元，i＝1,2,...,N。
S603a、发送N个第一调制符号。
在一些实施例中，该N个第一调制符号可以包含于第一信号中，终端设备可以向网络设备发送第一信号，该第一信号由上述N个频域资源单元承载，或者说，在N个频域资源单元上向网络设备发送第一信号。
在终端设备采用方式一发送UCI的情况下，对于网络设备来说，如图6b所示，其接收操作可以包括如下步骤：
S601a、接收来自终端设备的第一信号。
在一些实施例中，该第一信号由上述N个频域资源单元承载，该第一信号包括N个第一调制符号。
S602b、对第一信号进行物理层处理，得到UCI。
其中，该UCI包括N个UCI子段，UCI子段可参考上述相关说明，在此不再赘述。
在一些实施例中，网络设备对第一信号的物理层处理与终端设备对UCI子段的物理层处理相匹配。例如，终端设备对UCI子段的物理层处理包括速率匹配，那么网络设备对第一信号的物理层处理包括解速率匹配；终端设备对UCI子段的物理层处理包括调制，那么网络设备对第一信号的物理层处理包括解调制；终端设备对UCI子段的物理层处理包括码块级联，那么网络设备对第一信号的物理层处理包括解码块级联；终端设备对UCI子段的物理层处理包括信道编码，那么网络设备对第一信号的物理层处理包括信道译码；终端设备对UCI子段的物理层处理包括码块分割与CRC插入，那么网络设备对第一信号的物理层处理包括解码块分割和去CRC。
作为一种示例，网络设备得到UCI后，可以根据UCI进行相关处理，例如，UCI包括HARQ-ACK信息的情况下，根据该HARQ-ACK信息确定是否重传下行数据；或者，UCI包括SR的情况下，为终端设备调度上行资源；或者，UCI包括CSI的情况下，根据该CSI进行下行数据的预编码等，本申请对此不作具体限定。
基于该方案，一方面，将UCI分为N个UCI子段在N个频域资源单元上传输，使得每个频域资源单元上传输的UCI比特减少，从而可以增加冗余比特，即降低码率，提高传输可靠性。另一方面，N个频域资源单元相比于一个频域资源单元可以传输更多的UCI信息，在UCI包括CSI，且CSI的数据量较大的情况下，可以通过一次发送将CSI的全部数据量反馈给网络设备，从而提高CSI反馈的及时性，进而提高通信效率；再一方面，将UCI分为N个UCI子段，在该N个UCI子段的部分UCI子段传输成功的情况下，网络设备可以获得部分UCI，终端设备可以重发传输失败的部分，而无需重发全部UCI，从而可以降低资源开销。
方式二：
终端设备对UCI进行物理层处理后，通过复制的方式发送UCI。例如，通过复制调 制符号的方式发送UCI。
示例性的，以该UCI的比特数为A为例，如图8a所示，该方式二下，终端设备在N个频域资源单元上发送UCI，可以包括：
S801a、对A比特的该UCI进行物理层处理，得到第二调制符号。
其中，该第二调制符号也可以理解为该A比特的UCI子段对应的调制符号。
在一些实施例中，该UCI的比特数A和该UCI对应的CRC的比特数之和小于或等于第一阈值，第一阈值可参考上述方式一中的相关说明，在此不再赘述。
在一些实施例中，该物理层处理包括速率匹配，该速率匹配基于一个频域资源单元，可参考上述步骤S601a中的相关说明，在此不再赘述。
在另一些实施例中，该物理层处理除速率匹配外，还可以包括以下一项或多项：码块分割与CRC插入、信道编码、码块级联、或调制。在物理层处理包括上述列举的全部操作的情况下，如图9所示，为各个操作的执行流程，即对A比特的UCI进行码块分割与CRC插入后，进行信道编码，再对信道编码后的结果进行速率匹配，之后对速率匹配后的结果进行码块级联，最后进行调制。
S802a、将第二调制符号分别映射至N个频域资源单元中的每个频域资源单元。
也就是说，每个频域资源单元上映射的调制符号相同，均为第二调制符号。示例性的，如图9所示，在调制完成之后，终端设备将第二调制符号分别映射至每个频域资源单元。
S803a、发送每个频域资源单元中映射的第二调制符号。
在一些实施例中，上述每个频域资源单元中映射的第二调制符号，即N个相同的第二调制符号可以包含于第二信号中，终端设备可以向网络设备发送第二信号，该第二信号由上述N个频域资源单元承载，或者说，在N个频域资源单元上向网络设备发送第二信号。
在一些实施例中，该方式二也可以理解为A比特的UCI在N个频域资源单元上映射N次，或者说，A比特的UCI在N个频域资源单元上重复N-1次，或者说，A比特的UCI在N个频域资源单元上发送N次，或者说，在N个频域资源单元上发送了N份UCI。
在终端设备采用方式二发送UCI的情况下，对于网络设备来说，如图8b所示，其接收操作可以包括如下步骤：
S801b、接收来自终端设备的第二信号。
