本申请涉及通信技术领域，具体涉及一种信息传输方法及相关产品。
背景技术
对于物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)，在Rel-15新空口(New Radio，NR)系统中，PUCCH频域资源可以配置1到16个物理资源块(Physical Resource Block，PRB)。但是新空口非授权(New Radio Unliecensed，NR-U)系统中，由于占用带宽(occupied bandwidth，OCB)的限定，PUCCH上传输的信息需要用梳齿interlace进行映射。一个interlace的频域资源是10个或者11个PRB，导致在某些情况下，如PUCCH上的负载较大时，一个interlace对应的频域资源无法承载过多的负载量，则需要用2个或者多个interlace来传输。另外，为了提高interlace的频域资源的利用率，当PUCC为格式Format 2，在使用interlace的情况下，还可以通过正交码(Orthogonal Cover Code，OCC)对interlace的频域资源的物理资源块进行复用，进而增加用户复用数量。
但是，在增加用户复用数量时，会导致PUCCH上传输的信息重复内容较多，出现峰值平均功率比(PAPR—Peak to Average Power Ratio，PAPR)较高的问题，进而影响PUCCH上的信息传输进程。

具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。
本申请实施例可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。
本申请实施例对应用的频谱并不限定。例如，本申请实施例可以应用于授权频谱，也可以应用于免授权频谱。
图1为本申请实施例提供的一种通信系统构架示意图，所述通信系统包括网络设备和终端设备。如图1所示，网络设备可以与终端设备进行通信。该通信系统可以是5G通信系统(例如新空口(new radio，NR))、多种通信技术融合的通信系统(例如LTE技术和NR技术融合的通信系统)、或者后续演进通信系统。图1中所示的网络设备和终端设备的形态和数量仅用于举例，并不构成对本申请实施例的限定。
本申请中的终端设备是一种具有无线通信功能的设备，可以部署在陆地上，包括室内或室外、手持、可穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球、卫星上等)。该终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、智能家庭(smart home)中的无线终端等。终端设备也可以是具有无线通信功能的手持设备、车载设备、可穿戴设备、计算机设备或连接到无线调制解调器的其他处理设备等。在不同的网络中终端设备可以叫做不同的名称，例如：终端设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置、蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、5G网络或未来演进网络中的终端设备等。
本申请中的网络设备是一种部署在无线接入网用以提供无线通信功能的设备。例如，网络设备可以是蜂窝网络中接入网侧的无线接入网(Radio Access Network，RAN)设备，所谓RAN设备即是一种将终端设备接入到无线网络的设备，包括但不限于：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 Node B，或Home Node B，HNB)、基带单元(Base Band Unit，BBU)、管理实体(Mobility Management Entity， MME)；再例如，网络设备也可以是无线局域网(Wireless Local Area Network，WLAN)中的节点设备，例如接入控制器(access controller，AC)，网关，或WIFI接入点(Access Point，AP)；再例如，网络设备也可以是NR系统中的传输节点或收发点(transmission reception point，TRP或TP)等。
非授权频谱是国家和地区划分的可用于无线电设备通信的频谱，该频谱通常被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，不需要向政府申请专有的频谱授权。
为了让使用非授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，一些国家或地区规定了使用非授权频谱必须满足的法规要求。例如，通信设备遵循“先听后说(LBT)”原则，即通信设备在非授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在非授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。为了保证公平性，在一次传输中，通信设备使用非授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupancy Time，MCOT)。
但是在新空口非授权(New Radio Unliecensed，NR-U)系统，使用非授权频段进行信息传输时，由于对占用带宽(Occupied Bandwidth，OCB)的限制，在PUCCH上传输的信息进行频域映射时需要用梳齿interlace进行映射。
使用每个interlace进行映射时，需要按照该interlace所规定的映射规则对该PUCCH上的待传输信息进行映射。如图2所示，将待传输信息X(k)中在PUCCH所分配的物理资源块上，每个bit每隔4个物理资源块进行映射，从而得到传输数据X(k)的映射结果，然后，通过该PUCCH所分配的物理资源块将该映射结果发送出去。
另外，为了提高interlace的频域资源的利用率，当PUCC的格式为格式Format 2时，本申请中也将Format 2下的PUCCH称为PF2，在使用interlace的情况下，还可以通过OCC对interlace对应的频域资源上的物理资源块(Physical Resource Block，PRB)进行复用，以增加用户复用数量。
但是，在增加用户复用数量时，会导致PUCCH上传输的信息存在过多重 复内容，会出现PAPR较高的问题，进行影响PUCCH上的信息传输进程。
图3为本申请实施例提供的一种信息传输方法的流程示意图。该方法包括但不限于以下步骤：
301：当物理上行链路控制信道PUCCH的配置满足预设条件时，用户终端对所述PUCCH上的待传输信息进行扰码。
其中，该PUCCH的格式为格式Format 2。
其中，扰码实质上就是使用扰码序列(随机序列)与待传输信息进行乘积运算，以减少该待传输信息中数据重复概率。
PUCCH的配置由网络设备配置，对PUCCH的配置包括但不限于以下一种或几种的组合：interlace、interlace的数量、正交码长度OCC-Length、使用符号的数量Nrof Symbols，等等。
可选的，该预设条件可以包括上述配置的一种或几种的组合。例如，该预设条件可以为对PUCCH配置了interlace和/或对PUCCH配置的OCC-Length大于1，该预设条件还可以为使用interlace的数量大于第一阈值和/或Nrof Symbols大于第二阈值，本申请对预设条件的具体形式不做限定。
302：用户终端将扰码结果映射到与所述PUCCH对应的频域资源。
可以看出，在本申请实施例中，当格式为Format2的PUCCH的配置满足条件时，对PUCCH上的待传输信息进行扰码，从而避免将该待传输信息映射到频域资源后出现过多的重复内容，进而降低峰值平均功率比，提高数据传输效率。
图4为本申请实施例提供的另一种信息传输方法的流程示意图。该实施例中与图3所示的实施例相同的内容，此处不再重复描述。该方法包括但不限于以下步骤：
401：当物理上行链路控制信道PUCCH的配置满足预设条件时，用户终端使用预设调制方式对目标序列进行调制，得到扰码序列。
目标序列可以为目标比特序列，该目标序列可以是通过二进制随机生成器对初始参数进行处理得到的。即利用二进制随机生成器以及该初始参数生成一个随机二进制序列，将该二进制序列作为该目标序列。
该预设调制方式包括二进制相移键控(Binary Phase Shift Keying，BPSK)或者正交相移键控(Quadrature Phase Shift Keying，QPSK)。
举例来说，当目标序列为(0，1，0，0，1，1)时，如预设调制方式为调制BPSK，则得到扰码序列为(-1，1，-1，-1，1，1)；如预设调制方式为QPSK时，则得到扰码序列为((-1+j)/sqrt(2)，(1+j)/sqrt(2)，(1-j)/sqrt(2))。
进一步地，该初始参数是通过预设函数得到的，该预设函数的变量包括扰码索引(scrambling identity)。
需要说明的是，scrambling identity不是该预设函数的唯一自变量，该预设函数中还可以设置有其他变量；另外，该预设函数中包含scrambling identity的项可以不止一个，本申请对此均不做限定。
举例来说，该预设函数可以为：Init seed＝a*scrambling identity+b，其中，a和b为预设参数值，Init seed为初始参数；该预设函数还可以为：Init seed＝a*scrambling identity -1+b*scrambling identity -2+c，其中，scrambling identity -1为第一个scrambling identity、scrambling identity -2为第二个scrambling identity。例如，scrambling identity -1可以为Cell Identity、scrambling identity -2可以为配置值。可以理解的是，当一个scrambling identity没有对应取值时，可将该scrambling identity的取值置零。
其中，该扰码索引包括服务小区的小区标识(Cell Identity)、配置值、预设值(协议中提前设定好的值)中的一种或几种的组合。
具体来说，可以将Cell Identity、配置值、预设值中的任意一个值作为scrambling identity；也可以将Cell Identity、配置值、预设值中的两个值的均值作为scrambling identity；当然，也可以对该两个值进行组合，得到一个最终值，将该最终值作为scrambling identity；同样，可以将Cell Identity、配置值、预设值同时作为scrambling identity，也可以对该三个值进行组合，得到一个最终值，将该最终值作为scrambling identity。
举例来说，如Cell Identity为6、配置值为8、预设值为10。当该预设函数中包括一个scrambling identity项时，可以取该三个值中的任意一个值作为scrambling identity的取值；也可以先取两个值的平均值(如7或9)作为 scrambling identity的取值；或者，可以先通过预设函数依次获取两个值对应的两个初始参数，然后，对两个初始参数进行加权处理，得到上述的初始参数。也可以取该三个值的平均值8作为scrambling identity的取值；或者，也可以通过预设函数依次获取三个值分别对应的三个初始参数，然后，对得到的三个初始参数取值进行处理(如加权)，得到上述的初始参数。
可选的，上述Cell Identity可通过同步信号块(Synchronization Signal and PBCH block，SSB)得到，即在接入服务小区时，接收该服务小区发送的SSB，解析该SSB，即可得到该服务小区的Cell Identity。
可选的，上述配置值通过用户终端级别的无线资源控制(User Equipment specific Radio Resource Control，UE-specific RRC)配置信息指示。
可选的，该UE-specific RRC配置信息包括上行链路控制信道配置信源PUCCH-Config Information Element、物理上行链路控制信道资源信源PUCCH-Resource IE以及PUCCH-Format2 IE。
参阅表1，表2和表3。表1和表2示出了PUCCH-Resource IE两种配置形式；表3示出了PUCCH-Format2 IE的配置形式。
如表1所示，在PUCCH-Resource IE(也可以称为IE：PUCCH-Resource)配置了Scrambling Identity，同时也配置了PUCCH的格式为format 2；如表2所示，在PUCCH-Resource IE中可以配置是否需要进行扰码，以及扰码时所需的Scrambling Identity，以及PUCCH的格式为format 2。
因此，该配置值以及对PUCCH的配置可以通过PUCCH-Config IE指示；或，通过PUCCH-Resource IE指示；或，通过PUCCH-Format2 IE指示。即在每个信源的相关字段中读取该配置值，得到Scrambling Identity。
其中，对PUCCH-Config IE的配置可以与对上述配置方式相同，也可以不同，本申请对此PUCCH-Config IE的配置形式不做限定。

可选的，上述服务小区为该用户终端接入的小区，该服务小区包括主服务小区(Primary Cell，PCell)和/或辅服务小区(Secondary Cell，SCell)。
402：用户终端使用扰码序列对所述PUCCH上的待传输信息进行扰码。
如图5所示，使用扰码序列R(k)对待传输信息X(k)进行扰码，即将扰码序列R(k)与待传输信息X(k)的对应位进行相乘，得到扰码结果Y(k)。
403：用户终端将扰码结果映射到与所述PUCCH对应的频域资源。
可以看出，在本申请实施例中，当PUCCH的配置满足预设条件时，采用扰码序列对PUCCH上的待传输信息进行扰码，从而降低将该待传输信息映射到频域资源后的重复信息，进而降低峰值平均功率比，提高数据传输效率。
图6为本申请实施例提供的另一种信息传输方法。该实施例中与图3、图4所示的实施例相同的内容，此处不再重复描述。该方法包括但不限于以下步骤：
601：当物理上行链路控制信道PUCCH的配置满足预设条件时，用户终端使用预设调制方式对目标序列进行调制，得到扰码序列。
602：用户终端使用扰码序列对所述PUCCH上的待传输信息进行扰码。
603：用户终端将扰码结果映射到与所述PUCCH对应的频域资源。
604：用户终端通过频域资源向网络设备发送映射结果。
进一步地，网络设备在接收到该映射结果后，对该映射结果进行解扰码，得到该待传输信息。
具体来说，网络设备对映射结果进行解映射，得到扰码结果；然后，网络设备和用户终端具有相同的随机二进制生成器以及预设函数，用户终端在发送该映射结果时，可将扰码索引以及预设调制方式同步上报给网络设备。网络设备可以通过该预设函数生成同样的初始参数，同样，使用随机二进制生成器对该初始参数进行处理生成上述的扰码序列，使用该预设调制方式和该扰码序列得到目标序列。最后，使用目标序列对该扰码结果解扰码，得到该待传输信息。
可以看出，在本申请实施例中，在本申请实施例中，当PUCCH的配置满足预设条件时，采用扰码序列对PUCCH上的待传输信息进行扰码，从而降低将该待传输信息映射到频域资源后的重复信息，进而降低峰值平均功率比，提高数据传输效率。
