为更充分介绍本方案各实施例，首先对以下内容进行介绍：
1.MIMO；
在MIMO系统中，收发双方使用多副可以同时工作的天线进行通信。MIMO系统通常采用复杂的信号处理技术来显著增强可靠性、传输范围和吞吐量。发射机采用这些技术同时发送多路射频信号，接收机再从这些信号中将信息恢复出来。
不同的MIMO模式的共同目的是利用已知的空间相关性获得额外的分集增益或者频谱效率提升。例如长期演进(Long Term Evolution，LTE)协议中的MIMO模式主要有以下几种：
Mode 1：单天线工作模式；
传统无线制式的天线工作模式。
Mode 2：开环发射分集；
利用复数共轭的数学方法，在多根天线上形成了彼此正交的空间信道，发送相同的数据流，提高传输可靠性。
Mode 3：开环空间复用；
在不同的天线上人为制造“多径效应”，一个天线正常发射，其他天线上引入相位偏移环节。多个天线的发射关系构成复矩阵，并行地发射不同的数据流。这个复矩阵在发射端随机选择，不依赖于接收端的反馈结果，就是开环(Open Loop)空间复用。
Mode 4：闭环空间复用；
发射端在并行发射多个数据流的时候，根据反馈的信道估计的结果，选择制造“多径效应”的复矩阵，就是闭环(Close Loop)空间复用。
Mode 5：MU-MIMO(Multi-User Multiple-Input Multiple-Output，多用户-多输入多输出)；
并行传输的多个数据流是由多个用户设备(User Experience，UE)组合实现的，就是多用户空间复用，即MU-MIMO(Multi User MIMO)。
Mode 6：Rank＝1的闭环发射分集；
作为闭环空间复用的一个特例，只传输一个数据流，也就是说，空间信道的秩Rank＝1。这种工作模式起到的是提高传输可靠性的作用，实际上是一种发射分集的方式。
Mode 7：波束赋形(Beamforming)；
多个天线协同工作时，根据基站和UE的信道条件，实时计算不同的相位偏移方案，利用天线之间的相位干涉叠加原理，形成指向特定UE的波束。
当前MIMO系统的工作模式3～6都是利用不同的天线发送不同的数据流，以达到提升频谱效率的目的。MIMO多流传输的流数上限由天线数确定，在此基础上，在信道质量较好，或者说接收信号SNR(SIGNAL NOISE RATIO，信噪比)较大时，系统可以通过采用高阶调制的方式来进一步提升频谱效率。然而由于接收机最小EVM的限制，随着调制阶数的升高，系统的频谱效率存在着边际效应递减的问题。因此，在SNR足够大时，通过在MIMO多天线系统中引入FTN/OVTDM(Faster-than-Nyquist Signaling/Overlapped Time Division Multiplexing，超奎奈斯特/重叠时分复用)技术，利用多个天线进行信号的延时叠加发送，从而起到进一步提升频谱效率的作用。
传统的单天线系统中，FTN/OVTDM信号的生成通过将过采样后的信号通过成型滤波器来实现。在成型滤波器的设计的采样精度确定的前提下，叠加层数越高，要求的信号过采样率越高，这造成了高阶叠加对硬件的设计具有挑战性。而在多天线系统中，通过不同天线振子/端口以不同的时间延迟发送信号，在空口叠加形成FTN/OVTDM信号。通过利用MIMO系统中已有的多天线设计，实现了超奈奎斯特采样传输，减少了基带设计的复杂度和硬件成本。
2.超奈奎斯特传输，即Faster-than-Nyquist Signaling。
FTN/OVTDM是通过对发送信号进行移位叠加处理(又称波形编码)，人为地引入适量ISI(Symbol Interference，符号间干扰)和/或ICI(Carrier Interference，信道干扰)一种信号处理方法，其目的是加快码元发送速率，即增加每赫兹每秒(Hz*s)内发送的符号数量。其中，FTN的全称为
Faster-than-Nyquist，即超奈奎斯特。OVXDM(Overlapped X Division Multiplexing，X域重叠复用)(X代表任何域，时间T，空间S，频率F或混合H等)包括OVTDM(Overlapped Time Division Multiplexing，重叠时分复用)，OVFDM(Overlapped Frequency Division Multiplexing，频域重叠复用系统)和OVCDM(Overlapped code Division Multiplexing，重叠码分复用)，以及OVTDM和OVFDM的组合技术，其全称为Overlapped X-Domain Multiplexing，即X域重叠复用，可以用FTN(Faster Than Nyquist，多载波超奈奎斯特)指代。同时，引入的ISI和ICI会增加译码的复杂度，可能造成误码率的提升。然而，通过先进的译码算法可以抑制误码率提升带来的负面效应，综合来看仍然可以通过所述加快码元发送速率的方法提升信道容量。其表达式如下：

图2是本申请实施例提供的无时域重叠与有时域重叠的信号对比示意图，如图2所示，体现了ISI的产生，当T＝0.8时，即时域波形重叠系数τ＝0.8后，经处理后的信号在在各个采样点所在时刻上，携带其他采样点信息的脉冲波形幅度不为零，因此产生了ISI。
假设多径信道的冲激响应函数为h CH(t)，则经过信道后的信号可以等效地表示为：

其中
Figure PCTCN2021131838-appb-000008
FTN/OVTDM信号的生成主要有两种方式：1)在单天线系统中，可以通过对信号过采样+成型滤波的方式来等效生成，其效果类似为一个作用于调制级别的卷积编码器；2)在多天线系统中，我们可以采用更贴近其物理含义的方式来生成，即控制多天线的每个天线振子/端口按照既定的移位叠加原则，依次以T Δ的延迟来发送信号，不同天线振子/端口以不同延迟发送的信号在空口叠加，和信号的采样点之间引入了ISI，形成FTN/OVTDM信号。
超奈奎斯特传输是目前被认为可以突破奈奎斯特采样速率，进一步逼近信道容量物理极限的一种新型信号处理技术。其衍生技术为OVXDM。OVXDM/FTN技术在时域/频域基于波形编码理论人为引入了ISI和/或ICI，从而提高了码元发送速率，增加了等效信道容量。然而，波形编码后的信号对接收机的性能提出了更高的要求，增加了译码算法的复杂度以及硬件的功耗。一般来说，波形编码时的时频域重叠系数越大，即人为引入的ISI和ICI越严重，则接收机侧需要判断的状态数越多，接收算法的复杂度越高。
在城市里复杂的电磁波传输环境中，由于存在大量的散射、反射和折射面，造成了无线信号经不同路径到达接收天线的时刻不同，即传输的多径效应，不同路径信号造成的。当发送信号的前后符号经过不同路径同时抵达时，或者说，当后一个符号在前一个符号的时延扩展内到达时，即产生了ISI。类似的，在频域上，由于频偏效应，多普勒效应等原因，信号所在的各个子载波会产生频率上不同程度的偏移，造成原本可能正交的子载波产生重叠，即ICI。上述在信号传输过程中产生的ISI/ICI与发送时采用波形编码引入的ISI/ICI叠加，对接收机的译码能力产生了更高的要求。可以通过更加复杂的接收机算法对抗衰落信道。例如利用信道预均衡，联合信道译码的迭代算法等方法。但在实际应用中，一方面，实际系统受成本和功耗等条件限制，往往无法采用理想接收机，实现的译码算法复杂度有限，当ISI/ICI超出了一定阈值后，会无法正确译码。同时，接收机的译码复杂度增加时，也会增加能量消耗，不利于终端节能降耗。
因此，明显并不是所有的场景下FTN/OVTDM系统都优于传统MIMO系统。
因此，本申请各实施例的主要构思为：可以利用无线信道的先验信息，利用信道测量结果等，灵活调节多天线系统的工作模式，使其可以在FTN/OVTDM模式和传统MIMO工作模式间灵活切换，以利于接收机能供跟踪衰落信道的时变特性，始终保持在最佳的工作状态。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的信息传输方法及装置进行详细地说明。
图3是本申请实施例提供的信息传输方法的流程示意图，该方法应用于通信设备，如图3所示，该方法包括如下步骤：
步骤300，获取多个天线的信道质量；
步骤310，根据所述信道质量，确定天线工作模式；
步骤320，采用所述天线工作模式，进行信息传输；
所述天线工作模式包括：所述多个天线均采用多输入多输出MIMO方式工作的MIMO模式，所述多个天线均采用超奈奎斯特FTN方式工作的FTN模式，或所述多个天线中同一天线端口组采用FTN方式工作、不同天线端口组之间采用MIMO方式工作的MIMO-FTN模式，其中，每个天线端口组内包括至少1个天线。
具体地，MIMO传输利用了多天线之间的空间相关性，在发端采用了数字域波束赋形(即根据信道特性进行的MIMO预编码等)的方式提供了额外的增益。其本质是利用多天线提供的额外的空间自由度获得的增益，可以称之为MIMO增益。
而FTN信号利用了不同天线发送信号之间的延迟叠加特性，达到了在相同发送时间间隔(Transmit Time Interval，TTI)内发送更多信息比特的效果。例如当重叠层数K＝2时，相当于把采用奈奎斯特传输在2T时间内所要发送比特数在T时间内发送完成，从而获得额外的增益。其本质是利用收发端已知的信号波形叠加规则，增加了额外的编码自由度，达到了把信息按照编码规则压缩后发送提升频谱效率的作用，可以称之为FTN增益。
MIMO工作模式中，不同发射天线上的发送信号是完全同步的。即不同天线的发射信号叠加时，信号波形的波峰与波峰叠加，波谷与波谷叠加。通过对MIMO信道信息的测量，选择合适的预编码矩阵来获取多天线系统的额外好处，例如通过空时编码实现分集增益，或者通过预编码实现多流传输提升频谱效率。
具体地，本实施例中，MIMO中的多天线系统可以在两种或三种模式中无缝切换。
例如，在低信噪比(Signal Noise Ratio，SNR)下，MIMO模式可以获取可观的分集增益，保证了传输的可靠性；而在高SNR下，多流MIMO受限于高阶调制的EVM限制，对频谱效率的提升有限，则可以采用FTN模式。因此，可以通过对信道状态信息的测量和反馈，由发端和/或收端触发工作模式切换。
具体地，为了实现利用无线信道的先验信息，利用信道测量结果等，灵活调节多天线系统的工作模式，使其可以在多种工作模式间灵活切换，切换成FTN模式、MIMO模式或MIMO-FTN模式，并通过多种工作模式间灵活切换，使信号发送模式根据信道状态变化的优化；因此可以通过对多个天线的信道质量的测量和反馈，获取信道质量，并基于信道质量，确定天线工作模式，由发端和/或收端触发切换，最后基于确定的天线工作模式，完成信息传输，且对流程和信令进行了保护。
可以理解的是，本实施例中的多天线系统可以切换为以下工作模式：
1)模式一：MIMO模式。该模式下，天线按照传统方式，通过在每个天线通道上预置不同的系数，进行发送预编码，实现数字波束赋形。
2)模式二：FTN模式。图4是本申请实施例提供的多天线系统生成FTN/OVTDM符号的示意图，如图4所示，该模式下，天线按照FTN方式工作。即每个天线通道间隔一定时间发送信号，信号在空口叠加形成FTN信号。
3)模式三：MIMO-FTN模式。MIMO-FTN模式中，部分天线组成集合即天线端口组，组内天线 的信号进行叠加形成FTN信号，天线端口组间基于MIMO工作模式进行信息传输。
可以理解的是，天线端口组可以是以天线为单元进行的分组，即可以对多个天线进行分组得到天线端口组；
天线端口组也可以是以天线通道为单元进行的分组，即可以对多个天线通道进行分组得到天线端口组。
图5是本申请实施例提供的MIMO-FTN混合工作模式的传输示意图，以图5为例，图5中的多天线系统总共有八个天线。每个实线框内的天线分为一组，称为天线端口组。其中，天线端口组1内天线的信息以不同的延时[λ 0，λ 1，λ 2，λ 3]传输，天线端口组2内天线的信息以不同的延时[λ 0，λ 1，λ 2，λ 3]传输。在此基础上，天线端口组1和天线端口组2的信息，基于MIMO工作模式进行信息传输。
本申请实施例中，MIMO中的多天线系统可以工作在传统MIMO和FTN/OVTDM两种状态。在协议中，需要增加至少一种MIMO模式，本申请中可以称之为FTN模式，对应利用多天线生成FTN/OVTDM信号的传输。为方便描述，可以把传统的MIMO模式称之为MIMO模式。
本申请实施例中上下行定义如下：上行指终端侧比如用户设备到网络侧比如基站，下行指网络侧比如基站到终端侧比如用户设备。
可以理解的是，本实施例除了适用上下行信息传输，还可以适用于sidelink信息传输。
具体地，通信设备可以是网络侧设备，比如基站，则发端为网络侧，收端为终端侧，对应传输的信息为下行信息。
具体地，通信设备可以是终端，比如UE，则发端为终端侧，收端为网络侧，对应传输的信息为上行信息。
具体地，通信设备可以是终端，比如UE，其通信对端也为终端，则发端为终端，收端为终端，对应传输的信息为sidelink信息。
在本申请实施例中，通过基于信道状态信息，确定天线工作模式，进行信息的传输，在信息传输时可以实现根据信道状态自适应地选择合适的传输模式进行信息传输，灵活调节多天线系统的工作模式，实现了针对信道状态动态优化频谱效率，利于接收机能供跟踪衰落信道的时变特性，始终保持在最佳的工作状态。
可选地，根据所述信道质量，确定天线工作模式，包括以下至少一项：
在所述信道质量小于或等于第一阈值的情况下，确定天线工作模式是MIMO模式；
在所述信道质量大于或等于第二阈值的情况下，确定天线工作模式是FTN模式；
在所述信道质量大于第一阈值且小于第二阈值的情况下，确定天线工作模式是MIMO-FTN模式。
具体地，FTN/OVTDM系统相对传统OFDM系统的吞吐量优势主要在于高SNR区域。在高SNR区域，噪声对接收信号的影响程度相对较小，接收机易于根据已知的FTN/OVTDM的符号间编码的约束关系正确的进行译码，误码率很低。在低SNR区域，噪声对接收信号的影响程度相对较大，破坏了符号间编码的约束关系，使得误码率较高，不如传统的OFDM系统。
具体地，在基于信道状态信息，确定天线工作模式，可以基于信道状态信息中的信号与干扰加噪声比SINR来确定。
图6是本申请实施例提供的天线工作模式确定方法示意图，如图6所示，对某个天线集合比如天线端口组而言，当信道状态较好时，即信道质量大于或等于第二阈值，比如其接收信号SNR大于第二阈值，导致当FTN增益大于MIMO增益时，则可以切换为FTN模式；反之，当信道状态不好，信道质量小于或等于第一阈值，FTN增益小于MIMO增益时，则可以切换为MIMO波束赋形模式；信道质量大于第一阈值且小于第二阈值，则可以切换为MIMO-FTN模式；进一步的，还可以根据可用天线数量和所需的FTN重叠层数，决定天线的分组方式，和天线分组间的协作工作模式，比如当天线数量是FTN重叠层数的多倍时，可以确定天线工作模式是MIMO-FTN模式。
具体地，第一阈值及第二阈值可以是预先确定的，也可以是网络配置的，也可以是协议约定的。
本申请实施例，根据信道状况的不同，当接收SNR≥Thh(第二阈值)时利用FTN有较大增益，在接收SNR<Thl(第一阈值)时用传统MIMO效果较好，在Thl<SNR<Thh时利用混合模式，取得MIMO增益和FTN增益的权衡，进一步实现了针对SNR动态优化频谱效率的目的。
可选地，根据所述信道质量，确定天线工作模式之后，还包括：根据更新的信道质量，切换天线工作模式；采用切换后的天线工作模式，进行信息传输。
具体地，为了实现多天线系统根据信道质量进行工作模式的自适应切换，可以在确定天线工作模式之后，进一步监控更新后的信息传输情况，根据信息传输情况，确定需要切换天线工作模式。
例如，当前天线工作模式为FTN模式，可以在确定连续多次信息传输不满足传输条件的情况下，确定当前天线工作模式需要进行切换，可以根据更新的信道质量，确定可以切换至MIMO-FTN模式，适应当前信道质量的天线工作模式，因此可以对天线工作模式进行切换。
可以理解的是，更新的信道质量，可以是在确定需要切换天线工作模式后测量获得的信道质量；还可以是在确定天线工作模式之后的多次信道测量获得的信道质量的综合值或平均值。
具体地，在确定切换的天线工作模式并进行切换后，继续进行信息传输；
可以理解的是，本申请实施例中，确定信息传输是否满足条件时，可以以一个或多个数据块的传输为单位进行确定。
可选地，所述信道质量是根据第一信道质量参数确定的，所述第一信道质量参数包括：信号与噪声比SNR、信号与干扰加噪声比SINR、参考信号接收功率RSRP和参考信号接收质量RSRQ中的至少一项。
具体地，信道质量是根据第一信道质量参数确定的，可以包括：可由导频测量方式获取的SNR，SINR(Signal to Interference plus Noise Ratio，SINR)，参考信号接收功率RSRP(Reference Signal Receiving Power，RSRP)和参考信号接收质量(Reference Signal Receiving Quality，RSRQ)等，还可以包括多普勒频移，残留频偏(指经频偏纠正后的频率偏移)，多径数量和相对速度等，这些参数可以直接影响信号的频偏，ISI和ICI，也可以间接反映在误码率上。
可以理解的是，相对速度指发端和收端之间的径向速度。
可选地，当所述通信设备为终端时，获取多个天线的信道质量，包括：通过所述多个天线，接收下行参考信号；对所述下行参考信号进行测量，得到所述信道质量。
具体地，当通信设备为终端时，其通信对端为网络侧设备，则此次传输为上行传输，可以理解的是，可以基于信道互易性，在上行传输场景下，采用下行测量。
具体地，可以通过多个天线，接收网络侧设备发送的下行参考信息，并对下行参考信息进行测量，得到下行信道质量，作为上行信道质量的参考。
可以理解的是，本申请实施例中，上行传输场景下，还可以采用上行测量，通过基站对上行信道进行测量并将信道质量告知终端。
可选地，当所述通信设备为终端，且通信对端为终端时，获取多个天线的信道质量，包括：通过所述多个天线，发送sidelink参考信号；接收所述通信对端反馈的信道质量，其中，所述信道质量是所述通信对端根据所述sidelink参考信号测量得到的。
具体地，当通信设备为终端时，其通信对端还可以为终端，则此次传输为sidelink传输，同样可以进行信道测量。
具体地，可以向通信对端的终端发送sidelink参考信号，通信对端接收到sidelink参考信号后可以对sidelink参考信号进行测量，获得信道质量，并告知发端的终端，发端的终端即可接收通信对端反馈的信道质量。
可选地，当所述通信设备为网络侧设备时，获取多个天线的信道质量，包括：
通过所述多个天线，发送下行参考信号；
接收所述终端反馈的信道状态信息(Channel State Information，CSI)，得到所述信道质量，其中，所述CSI是所述终端根据所述下行参考信号测量得到的。
具体地，当通信设备为网络侧设备时，其通信对端为终端，此次传输为下行传输，则可以采用下行测量。
下行测量场景下，网络侧设备发送下行参考信号，终端根据下行参考信号测量信道，并发送反馈消息给网络侧，网络侧可以接收终端反馈的信道状态信息CSI。
可选地，当所述通信设备为网络侧设备时，获取多个天线的信道质量，包括：
通过所述多个天线，接收上行参考信号；
对所述上行参考信号进行测量，得到所述信道质量。
具体地，当通信设备为网络侧设备时，其通信对端为终端，此次传输为下行传输，还可以基于信道互易性，在下行传输场景下，采用上行测量。
上行测量场景下，终端侧发送上行参考信号，网络侧根据上行参考信号测量信道，得到所述信道质量。
可以理解的是，在下行传输场景下，采用上行测量，或者在上行传输场景下，采用下行测量的前提是信道互易性的假设。即由发端到收端的信道和从收端到发端的信道相似，比如可以用于时分复用(Time Division Duplexing，TDD)的场景。
可以理解的是，测量得到的信道质量可以用于确定天线工作模式以及确定FTN的重叠层数等。
可选地，当所述天线工作模式为MIMO-FTN模式时，所述方法还包括：
确定天线端口组内采用FTN方式工作时的重叠层数；
确定天线端口组间采用MIMO方式工作时的MIMO目标工作模式；
其中，采用所述天线工作模式，进行信息传输，包括：根据所述MIMO目标工作模式和所述重叠层数，进行信息传输。
具体地，MIMO-FTN模式中，部分天线组成集合即天线端口组，组内天线采用FTN方式使得信号叠加形成FTN信号，随后天线端口组间基于MIMO目标工作模式进行处理，获得MIMO-FTN信息。因此，可以在传输信息前首先确定天线端口组内采用FTN方式工作时的重叠层数以及天线端口组间采用MIMO方式工作时的MIMO目标工作模式。
具体地，可以采用重叠层数作为表示FTN/OVTDM信号特征的描述方式。
具体地，由于可以将天线端口组看做是虚拟天线端口，因此根据所述MIMO目标工作模式和所述重叠层数，进行信息传输时，可以将虚拟天线端口的FTN信息进行MIMO传输，则可以基于天线端口组测量信息进一步确定MIMO目标工作模式；
具体地，可以根据当前多天线系统的系统条件，以及所处的无线环境情况，确定MIMO目标工作模式。
