本申请主张在2022年09月16日在中国提交的中国专利申请号202211133193.9的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种基于混合调制的通信方法、装置及通信设备。
背景技术
在低功耗唤醒信号的设计中，存在一种基于开关键控(On-off Keying，OOK)调制的混合信号调制方法，第一数据符号可以是正交幅度调制(Quadrature Amplitude Modulation，QAM)、正交相移键控(Quadrature Phase Shift Keying，QPSK)等任意调制符号，而第二数据符号是OOK调制的符号，用ON/OFF或OFF/ON来表示0/1比特。通过按照OOK调制后的ON、OFF规律对第一数据符号进行叠加调制，最后得到混合数据符号流。
在上述混合调制信号生成方法中，第二数据流是在第一数据流符号中通过加入空白时间间隔来调制信息。在该方法中，混合调制信号的时间利用率较低：在保持第一数据流符号速率不变的情况下将大幅降低第一数据流符号的接收信号质量；或者保持接收信号质量不变但大幅降低第一数据流符号速率。因此，亟待设计一种高效的混合调制信号调制方法。

首先对本申请涉及的相关技术进行介绍。
一、相干解调
相干解调也叫同步检波，实现的关键是接收端要恢复出一个与调制载波严格同步的相干载波。实现相干解调通常需要利用乘法器，输入一路与载频相干(同频同相)的参考信号与载频相乘。图2展示了一种典型的相干解调接收机。具体地，由锁相环控制的压控振荡器产生一个与输入信号同频同相的载波信号，然后分别经过0度和90度相移器分成I、Q两路载波(其中，I为同相位(In-phase)分量，Q为90度相移(quadrature phase)分量)，这两路载波与接收信号相乘，经过滤波器滤掉高频分量后得到I、Q两路的基带信号。最终，对I、Q两路基带信号进行采样和判决后，可以得到相应的解调符号。
相干解调适用于所有线性调制信号的解调，包括脉冲幅度调制(Pulse Amplitude Modulation，PAM)(包括OOK、二进制振幅键控(Amplitude Shift Keying，ASK))、QAM、频移键控(Frequency-shift keying，FSK)、相移键控(phase-shift keying，PSK)等。
二、非相干解调
与相干解调相对应，非相干解调不需要恢复出相干载波。特别地，非相干解调不使用乘法器，不需要接收机和载波同步，所以比相干解调方式要简单，接收机实现难度和成本都较低。图3展示了一种非相干解调接收机的结构图。具体地，接收信号与同频的I、Q两路匹配滤波器相乘，经过低通滤波器、采样、平方求和、开根号后，得到接收信号的基带包络信号。最终，对基带包络信号进行判决后，得到相应的解调符号。
由于最终获得的信号是包络信号，非相干解调通常也被称为包络检波。显然，包络信号无法携带相位信息。对于任意的发送信号，经过非相干解调后最终只能获得与幅度相关的基带信号。因此，非相干解调只能适用于PAM(包括OOK、ASK)、FSK等不依赖相位调制信息(或利用I、Q两个支路调制独立信息)的调制方式。
三、脉冲幅度调制
脉冲幅度调制PAM是一种脉冲载波的幅度随基带信号变化的一种调制方式。该调制方式系统实现简单，并且可以基于非相干解调器实现解调。如图4所示为2阶PAM 调制的示意图，用高电平表示“1”，用低电平表示“0”，该调制方式也可以叫做OOK或ASK。图5所示为4阶PAM调制示意图，用4阶幅度的脉冲信号来承载信息比特，每个脉冲信号都可以携带两个信息比特。
四、正交幅度调制
正交幅度调制(QAM，Quadrature Amplitude Modulation)是一种在两个正交载波(I、Q支路)上进行幅度调制的调制方式。这两个载波通常是相位差为90度(π/2)的正弦波，因此被称作正交载波。这种调制方式因此而得名。在QAM中，数据信号由相互正交的两个载波的幅度变化表示。
M-QAM信号的通带射频信号波形的表达式为：
其中，g(t)为信号脉冲。
图6展示了典型的16-QAM信号和64-QAM星座图，其中横坐标和纵坐标分别表示I、Q支路的幅度。
五、频移键控
FSK是一种以数字信号控制载波频率变化的调制方式，是数字信号传输中用的最早的一种调制方式。此方式实现起来比较容易，抗噪声和抗衰减性能好，稳定可靠，是中低速数据传输最佳选择。二进制的FSK(Binary Frequency Shift Keying，BFSK)，通过频率的变化来表示0和1。同理，可以拓展到任意的多进制频率键控M-FSK。
BFSK的射频通带信号表达式可以写作：
由于FSK仅使用频率来表示信息，可以用非相干的方式进行解调。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的基于混合调制的通信方法进行详细地说明。
图7是本申请实施例提供的基于混合调制的通信方法的流程示意图之一。如图7所示，该方法包括以下步骤：
步骤700、第一设备将第一组比特信息调制为第一信号的频率、幅度和相位中的至少一项，将第二组比特信息调制为所述第一信号的频率。
可以理解的是，第一设备为调制端，可以是终端或网络侧设备。
第一设备将比特信息调制成基带或射频通带信号，其中，第一组比特信息被映射为调制信号(即第一信号)的频率、幅度和相位中的至少一项，第二组比特信息被映射为调制信号的频率，形成第一信号，第一信号即是一种混合调制信号。
在本申请实施例中，通过将第一组比特信息调制为第一信号的频率、幅度和相位中的至少一项，将第二组比特信息调制为所述第一信号的频率，实现了用统一的信号向接收端同时传输多组比特信息，提高了传输的灵活性和效率。
下面以一种混合调制信号为例说明具体的调制过程，该混合调制信号可以看作由常规的FSK调制和QAM调制复合构成，因此本实施例将其称为FSK-QAM信号。考虑2个可用频率(f1,f2)，2个可用幅度(a1,a2)和4个可用相位(θ1,θ2,θ3,θ4)。表1列出了幅度和相位的一种可能取值。
表1一种幅度和相位的取值
考虑传输2组比特信息，速率分别为3bit/调制信号以及1bit/调制信号。因此，第一组比特信息的3bit可以用幅度和相位来表示，而第二组比特信息的1bit可以用频率来表示。表2和表3分别列出了比特信息与频率、幅度和相位的一种可能的映射关系。表3还列出了每种映射关系下对应的I、Q支路幅度。
表2一种比特信息和频率的映射关系
表3一种比特信息和幅度、相位的映射关系
在频率、I支路幅度、Q支路幅度的三维坐标系下，混合调制信号的星座图可以表示成图8的形式。
图9展示了混合调制信号的一种调制过程：分别根据第一组比特信息和第二组比特信息映射得到频率f、幅度a、相位θ(或I、Q支路的幅度i、q)；将I、Q支路相应的幅度分别与振荡器根据f产生的信号进行混频，最后相加得到输出信号x(t)：
x(t)＝acos(θ)g(t)cos2πft-asin(θ)g(t)sin2πft
其中，对应表1、2、3，有a∈{a1,a2},θ∈{θ1,θ2,θ3,θ4},f∈{f1,f2}。
本实施例所述方案对于频率的调制方式容易拓展到最小频移键控MSK(Minimum Shift Keying)、高斯最小频移键控(Gaussian Filtered Minimum Shift Keying)、连续相位频移键控(continuous phase frequency shift keying)等利用频率承载信息的调制方式；而对于幅度、相位的调制则容易拓展到PSK、PAM、ASK、差分相移键控(Differential Phase Shift Keying，DPSK)、幅度相移键控(Amplitude Phase Shift Keying，APSK)等利用幅度和/或相位承载信息的调制方式。
可选地，根据第一配置信息，对所述第一组比特信息和第二组比特信息进行调制，所述第一配置信息用于指示第一调制参数。
所述第一调制参数包括以下至少一项：
a)可用的频率数量，或，频率的调制阶数；
b)可用的频率信息；
频率信息包括以下至少一项：频点、频率起始位置、频率间隔。
c)可用的幅度数量，或，幅度的调制阶数；
需要说明的是，可用的幅度数量，或，幅度的调制阶数取决于第一设备的能力。
d)可用的相位数量，或，相位的调制阶数；
e)可用的I支路和/或Q支路的幅度数量，或，I支路和/或Q支路的幅度调制阶数；
f)第一信号的星座点总数；
此处，星座点总数是指所有可能的不同混合调制信号的总数。
g)单个第一信号可表示的比特总数；或，第一信号的调制阶数；
单个混合调制信号可表示的比特总数，或，混合调制信号的调制阶数。
h)比特信息与第一信号频率的映射规则；
即比特信息与混合调制信号频率的映射规则。
i)比特信息与第一信号幅度的映射规则；
即比特信息与混合调制信号幅度的映射规则。
j)比特信息与第一信号相位的映射规则；
即比特信息与混合调制信号相位的映射规则。
k)比特信息与第一信号I支路幅度的映射规则；
l)比特信息与第一信号Q支路幅度的映射规则；
m)两组比特信息的传输模式，所述两组比特信息包括所述第一组比特信息和第二组比特信息；
可选地，所述传输模式包括：复用模式，分集模式或混合模式。
取决于比特信息之间的关系，两组比特信息的传输模式有复用模式、分集模式、混合模式。
所述复用模式是指各组比特信息包含或表征的信息是独立不相关的；
所述分集模式是指各组比特信息为相同信息，或者，所述两组比特信息的每组比特信息为相同信息具有关联性的不同表示；
可选地，相同信息经过编码、压缩、加密、切割、交织等处理后具有关联性的不同表示。
所述混合模式是指两组比特信息中的部分比特信息包含独立不相关的信息，其他比特信息是相同信息具有关联性的不同表示。
若存在来自多个信息源(比如不同的应用)的独立信息(下面称为多路信息)，复用模式可以将多路信息分别映射(或可选通过预处理)到不同组的比特信息中。比如，若只有两路信息，那么可以分别用第一组比特信息和第二组比特来传输这两路信息；若有大于两路信息，那么可以对这多路信息进行合并，然后最终映射到两组比特信息中。图10是本申请实施例提供的复用模式在调制端的示意图。
对于分集模式，主要针对单路信息的情况，该单路信息通过编码、压缩、加密、切割、交织等处理后，最终映射到两组比特信息中。显然，这两组比特信息是该单路信息的重复表示，或者是有关联的不同表示。图11是本申请实施例提供的分集模式在调制端的示意图。
对于混合模式，同样针对存在多路信息的情况，其中，部分信息以复用模式的方式映射到两组比特信息中的部分比特中；而剩余信息以分集模式的方式映射到两组比特信息的剩余比特中。混合模式的调制端示意图和图11一样，但区别在于最终得到的第一组比特信息和第二组比特信息所表示的原始信息不是完全独立的。
相应的，对于分集模式和混合模式，如果解调端能够解调出表示相同信息的多个比特信息，对其进行相应的处理(解码、解压缩、解密、解合并、合并、解交织等)后，获得发送的相同信息。
分集模式为同一路信息提供了冗余性，提高了传输可靠性，为解调端提供了灵活性。比如，若分别用两组比特信息传输相同信息，其中第一组比特信息用混合调制信号的相位表示，第二组比特信息用混合调制信号的频率表示，这样可以让解调端先尝 试进行非相干解调，在无法成功解调时再使用相干解调，从而可以降低解调端的功耗。
分集模式还可以为具有不同解调能力的接收端提供有差异的传输服务。比如，对于一路信息，可以通过具有优先级的分层压缩方法得到重要性不同的两组比特信息。混合调制信号采用不同维度表示这两组比特信息，比如用频率来表示重要性更高的比特流。那么，对于能力弱的接收设备可以采用非相干解调接收更为重要的那一组比特信息，获得有限度的服务；对于能力强的接收设备可以采用相干解调接收全部比特信息，获得完整的服务。
可选地，若频率、幅度、相位的调制阶数分别为F、A、P，那么一个混合调制信号总共可以表示log2(F)+log2(A)+log2(P)个比特信息。比特信息与频率、幅度、相位的映射可以是灵活的。比如，对于F＝4，P＝4的混合调制信号来说，共可以表示4个比特。那么，包含3个比特的第一组比特信息可以联合使用2个频率和4个相位来表示；而包含1个比特的第二组比特信息使用2个频率来表示。采用本申请实施例提供的方法可以实现灵活映射。结合前述实施例提到的多种传输模式，使得多路信息与混合调制信号中的频率、幅度、相位也能具有灵活的映射方式。
n)所述两组比特信息的时序关系。
混合调制信号中的第一组比特信息和第二组比特信息可以是灵活的时序对应关系。比如，图12是本申请实施例提供的两组比特信息的时序关系示意图，如图12所示，发送端可以每发送两次第一组比特信息时发送一次第二组比特信息。实际情况中，两组比特信息的对应关系可以是一对多，多对一，多对多，根据配置情况而定。
可选地，所述方法还包括：
所述第一设备根据第一信息，确定所述第一配置信息；
或者，接收所述第三设备发送的第一配置信息，所述第一配置信息是所述第三设备根据第一信息确定的；
其中，所述第一信息包括以下至少一项：第一设备的能力信息，第二设备的能力信息，信道状态情况；
其中，所述第二设备为所述第一信号的接收端。
可以理解的是，上述实施例提及的第一配置信息可以是第一设备确定的，具体根据第一信息确定。第一信息包括以下至少一项：第一设备的能力信息，第二设备的能力信息，信道状态情况。
所述第二设备为所述第一信号的接收端，或称为解调端，可以是终端或网络侧设备。
可选地，第一配置信息可以是第三设备确定的，具体地，第三设备根据第一信息确定第一配置信息，向第一设备发送第一配置信息。
可选地，第一设备向第三设备上报第一设备的能力信息。例如，进入连接态后，第一设备通过UE Capability Enquiry-UE Capability Information信令上报自己的UE能力信息，或者，通过UE Assistance Information信息上报自己的UE能力信息。或者，在初始注册或添加过程中，通过Initial UE message主动上报自己的UE能力信息。
第三设备可以是发送端(即调制端，第一设备)，接收端(即解调端，第二设备)，或第三方通信设备。
可选地，所述第一设备或第二设备的能力信息包括以下至少一项：
a)调幅能力；
包括支持的幅度信息，连续调幅或离散调幅及对应的连续或离散特征的状态数量。
b)调相能力；
包括支持的相位信息，连续调相或离散调相及对应的连续或离散特征的状态数量。
c)载波生成能力；
包括支持的频率信息及其数量等。
d)解调能力；
如支持相干解调或非相干解调能力。
e)同步能力；
包括是否支持相位同步、是否支持时间同步、同步精度、误差范围等。
f)天线能力
包括天线数量、天线阵列排列配置、频率响应情况等。
可选地，所述信道状态情况包括历史的信道状态信息，或，实时的信道状态信息。
历史的信道状态信息可以是曾经设备驻留时记录的信道状态信息。实时的信道状态信息可以是估计或是通过其它方式获得的信息状态信息。
在一些可选的实施例中，第一配置信息(即第一调制参数)可以是默认配置好的或出厂设置的。
可选地，所述第一组比特信息包括以下之一：唤醒指示信号，寻呼消息，控制命令，指示信息。
混合调制信号在传输控制信令方面具有重要优势，比如唤醒指示信号。由于非相干解调较为简单，功耗比较低，适合长时间开启。因此，可以将寻呼消息、控制命令(如媒体访问控制控制元素(MAC Control Element，MAC CE))、指示信息(如侧链路控制信息(Sidelink Control Information，SCI)，下行控制信息(Downlink Control Information，DCI))等的比特信息调制到混合调制信号的频率部分。
以唤醒信号为例，可以将混合调制信号的频率变化用于承载唤醒序列的比特信息，而幅度、相位则用于承载具体的寻呼(Paging)信号位置、初始随机接入机会(RACH Occasion，RO)等信息。那么，当接收设备用非相干解调的解调端接收到唤醒序列后，开启相干解调的解调端接收剩余的信息。该方案一方面能让接收设备以较低的功耗持续监听唤醒信息，降低唤醒时延；另一方面还能为接收设备提供足够的辅助信息，帮助快速建立连接，比如无线资源控制(Radio Resource Control，RRC)连接。
可选地，在部分比特信息已被预调制为第一符号的情况下，对比特信息进行调制包括：
对所述第一符号进行第一处理，获得一个或多个第二符号；
若第一符号来自第一组比特信息，则将第二符号调制为第一信号的频率、幅度和相位中的至少一项；
若第一符号来自第二组比特信息，则将第二符号调制为第一信号的频率；
其中，所述第一符号包括单维调制符号或多维调制符号；所述第一处理包括以下至少一项：直接映射、交织、扩展、加扰。
可以理解的是，发送端在接收原始的一路或多路信息时，可能部分比特信息已经被调制成了第一符号，部分比特信息可以是第一组比特信息，第二组比特信息，或者，第一组比特信息的部分比特信息，第二组比特信息的部分比特信息，比如OFDM、QAM符号等。预调制的第一符号会占据混合调制信号的部分维度，比如QAM符号需要用幅度和相位进行承载。此时，混合调制信号的剩余维度，比如频率可以用于承载剩余的比特信息。
另外，第一符号可以直接被映射到混合调制信号的相应维度(比如QAM信号的幅度相位直接映射到混合调制信号的幅度和相位)；或者，经过交织、扩展、加扰等至少一项处理形成一个或者多个第二符号(扩展会增加符号的数量)，然后映射到一个或多个混合调制信号的相应维度进行承载。
其中，交织是指：交换多个符号的位置，变成一组新的符号
扩展是指：将一个符号复制成多个新的符号，其中复制到每个新的符号时可以进行对原符号进行按照约定规则的修改(比如调整幅度和相位)。
加扰是指：将原符号进行按照约定规则的修改，变成新的符号
第一符号可以是单维调制符号或多维调制符号。
其中，单维调制即只在电磁波的幅度、相位、频率等维度上的其中一个维度进行信息调制，典型的单维调制有：ASK调制、PSK调制、FSK调制等。
多维调制是指利用多个维度表示比特信息，例如，二维调制在电磁波的幅度、相位、频率等维度上的其中两个维度上进行联合调制，典型的二维调制有：QAM调制、无载波幅相调制(Carrierless Amplitude-Phase，CAP)调制、APSK调制等。
可选地，所述方法还包括：
向第二设备发送所述第一信号，其中，所述第二设备包括多个不同的接收设备，或者，相同设备的不同解调端，或者，相同设备的相同解调端。
需要说明的是，前述实施例中提及的第二设备，可以是多个不同的接收设备的不同解调端，也可以是相同接收设备的不同解调端，或者，第二设备是相同设备的相同解调端。
如图13所示，对于单接收设备的场景，发送端发送混合调制信号，系统配置或发送端指示接收端解调混合调制信号中的部分或全部比特信息。
如图14所示，对于多接收设备的场景，一种情况是不同设备独立地进行解调。若分布在网络中的UE的能力有差异，比如部分UE只能解调混合调制信号中的部分比特信息，另外一部分UE能够解调混合调制信号中的全部比特信息。此时，发送端可利用统一的调制方式就同时为不同的用户提供信息传输，降低了调度和传输时延。
如图15所示，对于多接收设备的场景，另外一种情况是不同设备协作进行解调。同样考虑分布在网络中的UE的能力有差异，不同UE只能解调混合调制信号中不同部分的比特信息。比如，若UE1只能解调第一部分比特信息，UE2能够解调全部或第二部分比特信息，那么UE2可以在完成第二部分比特信息解调之后将解调出的信息传输给UE1，UE1将解调出的第一部分比特信息和来自于UE2传输的第二部分比特信息进行合并，从而解调出发送端发送的混合调制信号的所有比特信息。通过UE之间的协作，实现联合解调。这种方式适合于UE能力弱，但对速率有要求的场景，但要求UE和UE之间能够基于类似于sidelink的数据和信令传输。
可选地，所述方法还包括：
向所述第二设备发送第一指示信息，所述第一指示信息用于指示第一调制参数。
可以理解的是，第一指示信息为调制端发送给解调端的指示信息，以指示解调端如何对接收到的混合调整信号进行解调。
第一调制参数包括的具体内容可以参考前述实施例的描述，在此不再赘述。
本申请实施例实现了用统一的信号向不同的接收设备或解调端同时传输多组比特信息，并提供了灵活的比特映射和传输模式，能够满足不同接收设备/解调端在速率、复杂度、功耗等方面的差异化需求，提高了传输的灵活性和效率。
图16是本申请实施例提供的基于混合调制的通信方法的流程示意图之二。如图16所示，该方法包括以下步骤：
步骤1600、第二设备接收第一信号，其中，所述第一信号为用频率、幅度和相位中的至少一项调制第一组比特信息，用频率调制第二组比特信息得到的信号；
步骤1601、所述第二设备解调所述第一信号，确定并根据所述第一信号的频率、幅度和相位中的至少一项，得到第一组比特信息；或，确定并根据所述第一信号的频率，得到第二组比特信息；或，确定并根据所述第一信号的频率、幅度和相位中的至少一项，得到第一组比特信息和第二组比特信息。
可以理解的是，第二设备为解调端，可以是终端或网络侧设备。
第二设备接收第一信号，其中，所述第一信号为用频率、幅度和相位中的至少一项调制第一组比特信息，用频率调制第二组比特信息得到的信号，第二设备对所述第一信号进行解调，可以得到所述第一组比特信息和所述第二组比特信息的至少一者。
第一信号是为用频率、幅度和相位中的至少一项调制第一组比特信息，用频率调制第二组比特信息得到的信号，因此，在解调端，确定并根据所述第一信号的频率、幅度和相位中的至少一项，得到第一组比特信息；或，确定并根据所述第一信号的频率，得到第二组比特信息；或，确定并根据所述第一信号的频率、幅度和相位中的至少一项，得到第一组比特信息和第二组比特信息。
下面以前述实施例中提到的混合调制信号为例，描述一种混合调制信号的解调方式，分为非相干解调和相干解调。
图17展示了一种非相干解调的解调端结构图。首先对接收信号y(t)进行下变频和低通滤波、匹配滤波，此时就能得到在f1和f2两个频率I、Q支路的幅度，然后对其平方求和，得到信号在不同频率上的能量，据此判决信号所在的频率(比如取最大值所在频率)，最终映射到比特信息。
图18展示了一种相干解调的解调端结构图。图中的振荡器为具有同步功能的振荡器，可以产生相位为θ'的载波，补偿接收信号的相位偏差，从而得到准确的I、Q支路幅度。通过求出每个频率对应的I、Q支路幅度与混合调制信号星座(如图8)中的所有星座点对应的I、Q支路幅度的欧氏距离，可以判决得到最接近的频率、幅度和相位，从而映射得到比特信息。除了图中描述的输出两组比特信息，也可以根据解复用相关配置对比特信息进行分割、筛选等操作，只输出所需的比特信息。值得注意的是，此处不限定提供同步载波的振荡器的实现方式，通常有锁相环、延迟反馈锁相环等，也可以通过导频估计相位偏差。
本实施例以前述实施例形成的混合调制信号为例阐述了解调端的一种可能实现，但相应的思想可以拓展到任意混合调制信号中，比如当大于两个频率时增加振荡器的数量、改变判决准则、映射大于1路或2路比特信息等。
