Description

通信方法、设备和存储介质 技术领域
本申请涉及通信领域，具体涉及一种通信方法、设备和存储介质。
背景技术
在通信感知一体化系统中，由于使用相同的时间、频率和功率等资源就可实现数据传输和目标感知两大业务功能，从而受到业界越来越多的重视。在信号特性方面，由于正交频分复用技术(Orthogonal Frequency Division Multiplexing，OFDM)波形在频谱效率、干扰抑制、与多输入多输出(Multiple-Input Multiple-Output，MIMO)技术良好适配结合等方面的显著优势，OFDM波形已在4G/5G移动系统得到广泛应用。此外，由于OFDM信号的模糊函数呈现单一尖峰形状，具有良好的距离分辨率特性，因此也能很好地去承担无线感知任务。基于上述两个原因，通感一体化融合波形设计中，还是以OFDM作为主要调制方式。
在基于OFDM波形的通感一体化系统中，用于感知的信号通常是由多个资源块组成，这些资源块携带不同用户的数据，由于用户的信道环境不同，不同资源块的功率、采用的调制方式等都可能有很大差异，并且，随着用户业务需求、信道环境的变化，上述资源分配功率、调制方式等还会动态变化。不同用户资源块的功率、调制方式差异会降低感知信号的有效相关带宽，进而降低了系统的距离分辨率；资源分配功率、调制方式的动态变化会导致感知信号的有效相关带宽动态变化，进而影响了感知性能的稳定性。

具体实施方式
下文中将结合附图对本申请的实施例进行说明。以下结合实施例附图对本申请进行描述，所举实例仅用于解释本申请，并非用于限定本申请的范围。
在一实施例中，图1是本申请实施例提供的一种通信方法的流程图。本实施例可以由第一通信节点执行。其中，第一通信节点可以为网络侧(比如，基 站)。如图1所示，本实施例中的通信方法包括：S110-S120。
S110、确定第一类型子载波集合和第二类型子载波集合。
其中，第一类型子载波集合中每个第一类型子载波与第二类型子载波集合中的一个或多个第二类型子载波在同一个资源块；第一类型子载波用于通信信息和感知信息的传输，第二类型子载波只用于通信信息的传输。
在实施例中，第一类型子载波集合包含同时用于通信信息和感知信息传输的多个子载波，即第一类型子载波集合中所有的第一类型子载波既可以用于通信信息的传输，也可以用于感知信息的传输。
在实施例中，第一通信节点基于子载波的分配方式对第一类型子载波和第二类型子载波进行分配，即确定每个第一类型子载波对应的子载波索引和每个第二类型子载波对应的子载波索引，然后将第一类型子载波组合得到对应的第一类型子载波集合，以及将第二类型子载波组合得到对应的第二类型子载波集合。
S120、将第一类型子载波集合和第二类型子载波集合发送至第二通信节点。
在实施例中，在第一通信节点完成第一类型子载波和第二类型子载波的分配之后，将第一类型子载波集合和第二类型子载波集合发送至第二通信节点，以使第二通信节点采用第一类型子载波集合中的第一类型子载波对通信信息和感知信息进行传输，以及采用第二类型子载波集合中的第二类型子载波进行通信信息的传输。
在一实施例中，第一类型子载波和第二类型子载波的分配方式均包括下述之一：等间隔分配方式；非等间隔分配方式；时变分配方式。在实施例中，第一通信节点可以采用等间隔分配方式、非等间隔方式或时变分配方式分配第一类型子载波和第二类型子载波。其中，第二类型子载波只用于通信。在一实施例中，等间隔分配方式指的是相邻两个第一类型子载波之间的第二类型子载波个数是相同的，且相连两个第二类型子载波之间的第一类型子载波个数是相同的；非等间隔分配方式指的是相邻两个第一类型子载波之间的第二类型子载波 个数是不同的，且相邻两个第二类型子载波之间的第一类型子载波个数是不同的；时变分配方式指的是在不同时隙分配不同的子载波作为第一类型子载波。
在一实施例中，采用专用信令或公共信令将第一类型子载波集合和第二类型子载波集合发送至第二通信节点。在实施例中，第一通信节点可以通过专用信令或公共信令向第二通信节点通知第一类型子载波集合和第二类型子载波集合。示例性地，第一通信节点可以采用专用信令向第二通信节点发送第一类型子载波集合；或者，第一通信节点可以采用公共信令向第二通信节点发送第一类型子载波集合。其中，专用信令是第一通信节点发送至某一个第二通信节点的，而公共信令是第一通信节点发送至多个第二通信节点的。示例性地，假设第一类型子载波集合包括：子载波0、子载波3、子载波6、子载波9……子载波99，其中，子载波0-11为资源块1，子载波12-23为资源块2，并且，第一通信节点向第二通信节点分配资源块1，则第一通信节点只需要通过专用信令向第二通信节点通知子载波0、子载波3、子载波6和子载波9为第一类型子载波；若不同第二通信节点分配的资源块不同，则第一通信节点可以通过公共信令向第二通信节点发送所有第一类型子载波的索引，从而第一通信节点无需向每个第二通信节点发送一个专用信令，以通知对应的第一类型子载波集合。
在一实施例中，在所述第一类型子载波携带通信信息的情况下，应用于第一通信节点的通信方法，还包括：采用专用信令或公共信令将第一类型子载波的功率参数发送至第二通信节点，其中，功率参数小于预设功率参数门限值。在实施例中，功率参数用于表征每两个第一类型子载波所对应功率之间的差值。在一实施例中，功率参数可以包括功率方差，也可以包括功率偏差值，对此并不进行限定。
在实施例中，相邻两个第一类型子载波之间的功率参数小于预设功率参数门限值，是为了避免相邻两个第一类型子载波的功率之间出现较大幅度的变化，进而避免大幅度地降低感知信号的有效相关带宽，保证了感知性能的稳定性。示例性地，预设功率参数门限值可以为0dB-3dB之间的任意一个值。
在实施例中，相邻两个第一类型子载波之间的功率参数可以是相同的，也可以是不相同的。示例性地，假设第一类型子载波集合包括：子载波2、子载波4、子载波6和子载波8，则子载波2和子载波4之间的功率参数，与子载波4和子载波6之间的功率参数可以是相同的，也可以是不相同的。
在一实施例中，在第一类型子载波携带通信信息，且第二通信节点采用正交幅度调制(Quadrature Amplitude Modulation，QAM)调制方式的情况下，应用于第一通信节点的通信方法，还包括：采用专用信令或公共信令向第二通信节点发送第一类型子载波与第二类型子载波之间的功率比例。在实施例中，在第一通信节点每次调度资源的情况下，若第一通信节点为第二通信节点分配的资源包括第一类型子载波，且第二通信节点采用QAM调制方式的情况下，第一通信节点向第二通信节点发送第一类型子载波集合，以及第一类型子载波集合中第一类型子载波与第二类型子载波之间的功率比例。在一实施例中，第一类型子载波集合中所有的第一类型子载波的功率可以相同，或者，第一类型子载波中相邻两个第一类型子载波的功率参数小于预设功率参数门限值，从而在感知角度可以最大化感知信号的有效相关带宽。在实施例中，第一通信节点向第二通信节点发送第一类型子载波集合，以及第一类型子载波集合中第一类型子载波与第二类型子载波之间的功率比例，第一类型子载波可以与第二类型子载波一样，可以采用QAM方式携带通信信息，从而可以将感知对通信的影响最小化。
在一实施例中，专用信令包括下述之一：物理下行控制信道(Physical Downlink Control Channel，PDCCH)；下行控制信息(Downlink Control Information，DCI)；物理下行共享信道(Physical Downlink Shared Channel，PDSCH)；媒体接入控制(Media Access Control，MAC)控制单元(Control Element，CE)信令。
在一实施例中，在第一类型子载波携带通信信息，且第二通信节点采用QAM方式的情况下，每个第一类型子载波与第二类型子载波之间的功率比例恒 定；并且，第一类型子载波所携带的通信信息占用前两个比特，以及其它比特为预设值。在实施例中，第一类型子载波之间的功率比例恒定，可以理解为，第一类型子载波集合中每两个第一类型子载波之间的功率比值(或差值的绝对值)是一个定值或者该比值(或差值的绝对值)小于一个预设的门限值。示例性地，第一类型子载波集合中包括：子载波1、子载波3和子载波5，并且，子载波1的功率为1，子载波3的功率为2，子载波5的功率为4，则子载波1与子载波3之间的功率比例，以及子载波5与子载波3之间的功率比例均为2。在实施例中，为了降低对通信性能的影响，在QAM调制方式中，第一类型子载波携带通信信息的情况下，可以只占用前两个比特，并且其它比特为预设值，从而可以使QAM调制方式等效于正交相移键控(Quadrature Phase Shift Keying，QPSK)调制方式。其中，其它比特的预设值可以为1。
在一实施例中，图2是本申请实施例提供的另一种通信方法的流程图。本实施例可以由第二通信节点执行。其中，第二通信节点可以为终端，比如，用户设备(User Equipment，UE)。如图2所示，本实施例中的通信方法包括：S210-S220。
S210、接收第一通信节点发送的第一类型子载波集合和第二类型子载波集合。
其中，所述第一类型子载波集合中每个第一类型子载波与所述第二类型子载波集合中的一个或多个第二类型子载波在同一个资源块；所述第一类型子载波用于通感一体化的信息传输，所述第二类型子载波只用于通信信息的传输。
S220、根据第一类型子载波集合中的第一类型子载波和第二类型子载波集合中的第二类型子载波进行信息传输。
在实施例中，第一通信节点确定第一类型子载波集合和第二类型子载波集合之后，将第一类型子载波集合和第二类型子载波集合发送至第二通信节点；在第二通信节点接收到第一类型子载波集合和第二类型子载波集合之后，第二 通信节点根据第一类型子载波进行通信信息和感知信息的传输，或者，采用第二类型子载波进行通信信息的传输。
在一实施例中，第一类型子载波和第二类型子载波的分配方式均包括下述之一：等间隔分配方式；非等间隔分配方式；时变分配方式。
在一实施例中，接收第一通信节点发送的第一类型子载波集合和第二类型子载波集合，包括：接收第一通信节点采用专用信令或公共信令发送的第一类型子载波集合和第二类型子载波集合。
在一实施例中，在所述第一类型子载波携带通信信息的情况下，应用于第二通信节点的通信方法，还包括：接收第一通信节点采用专用信令或公共信令发送的第一类型子载波的功率参数，其中，所述功率参数小于预设功率参数门限值。
在一实施例中，功率参数包括下述之一：功率方差；功率偏差。
在一实施例中，在第一类型子载波携带通信信息，且第二通信节点采用QAM调制方式的情况下，应用于第二通信节点的通信方法，还包括：
接收第一通信节点采用专用信令或公共信令发送的第一类型子载波和第二类型子载波之间的功率比例。
在一实施例中，专用信令包括下述之一：PDCCH；DCI；PDSCH；MAC CE信令。
在一实施例中，在第一类型子载波携带通信信息，且第二通信节点采用QAM方式的情况下，每个第一类型子载波与第二类型子载波之间的功率比例恒定；
并且，第一类型子载波所携带的通信信息占用前两个比特，以及其它比特为预设值。
在此需要说明的是，对应用于第二通信节点的通信方法中第一类型子载波集合、第一类型子载波之间的功率参数、预设功率参数门限值、功率比例、第一类型子载波的分配方式等参数的解释，可参见上述应用于第一通信节点的通 信方法中对应参数的描述，在此不再赘述。
在一实施例中，图3是本申请实施例提供的又一种通信方法的流程图。本实施例可以由第一通信节点执行。其中，第一通信节点可以为基站。如图3所示，本实施例中的通信方法包括：S310-S320。
S310、确定用于发送第一类型信号的目标符号。
其中，第一类型信号为通感一体化的信号。
在实施例中，第一类型信号指的是可以同时用于感知和通信的信号，即通感一体化的信号。在实施例中，第一通信节点可以从上行与下行进行切换之间的时隙(即下行时隙和上行时隙之间的时隙)中选择至少一个符号，作为目标符号，以用来传输第一类型信号。
S320、采用目标符号向第二通信节点发送第一类型信号。
在实时中，第一通信节点确定目标符号之后，可以采用该目标符号向第二通信节点发送第一类型信号。在实施例中，感知信号接收机可以利用特殊子帧的保护周期接收目标回波信号，拓展了保护周期的作用，降低了感知信号的开销，并且，并未对保护周期在通信信号的作用造成影响。
在一实施例中，在第一通信节点处于长期演进(Long Term Evolution，LTE)时分双工(Time Division Duplex，TDD)的通感一体化系统的情况下，目标符号包括：下行导频时隙(Downlink Pilot Time Slot，DwPTS)的最后K个符号；
在第一通信节点处于新空口(New Radio，NR)TDD的通感一体化系统的情况下，目标符号包括：一个时隙中下行符号的最后K个符号；其中，K为大于等于1的正整数。
在一实施例中，针对基于LTE TDD的通感一体化系统，第一通信节点可以在特殊子帧中DwPTS的最后K个符号发送第一类型信号；针对基于NR TDD的通感一体化系统，第一通信节点可以在一个时隙的下行符号中最后K个符号发送第一类型信号。
在一实施例中，图4是本申请实施例提供的再一种通信方法的流程图。本实施例可以由第二通信节点执行。其中，第二通信节点可以为终端。如图4所示，本实施例包括：S410。
S410、接收第一通信节点采用目标符号发送的第一类型信号。
其中，第一类型信号为通感一体化的信号；目标符号为用于发送第一类型信号的符号。
在一实施例中，在第一通信节点处于LTE TDD的通感一体化系统的情况下，目标符号包括：DwPTS的最后K个符号；
在第一通信节点处于NR TDD的通感一体化系统的情况下，目标符号包括：一个时隙中下行符号的最后K个符号；其中，K为大于等于1的正整数。
在此需要说明的是，对应用于第二通信节点的通信方法中目标符号、第一类型信号等参数的解释，可参见上述应用于第一通信节点的通信方法中对应参数的描述，在此不再赘述。
在一实施例中，以第一通信节点为基站，第二通信节点为UE，以及功率参数为功率方差为例，并且，基站采用等间隔分配方式分配第一类型子载波(即用于感知和通信一体化的子载波)，即第一类型子载波在频域上是等间隔的。
在实施例中，基站分配一部分子载波用于通信(即第二类型子载波)，另一部分子载波用于感知和通信一体化(即第一类型子载波)。基站通过专用或公共信令通知UE用于感知和通信一体化的子载波集合(即第一类型子载波集合)。比如，基站可以采用专用信令通知部分用于感知的子载波集合，该集合可以与分配给UE用于通信的子载波(即第二类型子载波集合中的第二类型子载波)在同一个资源块。再比如，基站可以采用公共信令通知用于感知的子载波集合整体。其中，第一类型子载波之间的功率方差应小于预设功率方差门限值，可选的，该预设功率方差门限值可以设定为0dB～3dB间的一个值(上述门限值 不需要通知UE)。图5是本申请实施例提供的一种第一类型子载波和第二类型子载波的分配示意图。如图5所示，选取子载波序号为双数的子载波作为第一类型子载波(比如，sub-carrier2、sub-carrier4、sub-carrier6……sub-carrier N-1)，并且，相邻两个第一类型子载波之间是等间隔的。其中，N为偶数。
在一实施例中，以第一通信节点为基站，第二通信节点为UE，以及功率参数为功率方差为例，并且，基站采用非等间隔分配方式分配第一类型子载波(即用于感知和通信一体化的子载波)。
在实施例中，基站分配一部分子载波用于通信(即第二类型子载波)，另一部分子载波用于感知和通信一体化(即第一类型子载波)。基站通过专用或公共信令通知UE用于感知和通信一体化的子载波集合(即第一类型子载波集合)。在实施例中，第一类型子载波之间的功率方差应小于预设功率方差门限值，可选的，该预设功率方差门限值设定为0dB～3dB间的一个值(上述门限值不需要通知UE)。图6是本申请实施例提供的另一种第一类型子载波和第二类型子载波的分配示意图。如图6所示，相邻两个第一类型子载波之间是非等间隔的。比如，第一类型子载波为sub-carrier1、sub-carrier4、sub-carrier N-2、sub-carrier N，并且，sub-carrier1和sub-carrier4之间相差两个子载波，sub-carrier N-2和sub-carrier N之间相差一个子载波。其中，N为大于1的正整数。
在一实施例中，以第一通信节点为基站，第二通信节点为UE，以及功率参数为功率方差为例，并且，基站采用时变分配方式分配第一类型子载波(即用于感知和通信一体化的子载波)。
在实施例中，基站采用时变分配方式在不同时隙分配不同子载波作为第一类型子载波，其功率方差小于预设功率方差门限值，并用广播方式告知UE。
在实施例中，基站分配一部分子载波用于通信(即第二类型子载波)，另一部分子载波用于感知和通信一体化(即第一类型子载波)。基站通过专用或 公共信令通知UE用于感知和通信一体化的子载波集合(即第一类型子载波集合)。其中，第一类型子载波之间的功率方差应小于预设功率方差门限值。在一实施例中，该预设功率方差门限值设定为0dB～3dB间的一个值(上述门限值不需要通知UE)。图7是本申请实施例提供的又一种第一类型子载波和第二类型子载波的分配示意图。如图7所示，在不同的时隙，基站分配不同的子载波作为第一类型子载波，并通过专用或公共信令通知UE。示例性地，在时隙t1，采用sub-carrier2、sub-carrier4……sub-carrier N-1作为第一类型子载波，而在时隙t2，采用sub-carrier1、sub-carrier4……sub-carrier N-1作为第一类型子载波。
在一实施例中，以第一通信节点为基站，第二通信节点为UE，以及功率参数为功率方差为例，并且，基站向UE发送第一类型子载波和第二类型子载波之间的功率比例，以及UE采用QAM调制方式。图8是本申请实施例提供的一种下行资源的分配示意图。如图8所示，基站向UE进行频域资源的分配。其中，基站进行下行资源的分配过程，指的是基站为UE分配子载波的过程，可以包括如下步骤：用户服务(user service)；资源调度(resource scheduler)、资源分配(resource allocation)、反馈(feedback)。其中，在资源调度的过程中，可以将功率比例(power ratio)发送至UE。
在实施例中，基站使用专用或公共信令向UE通知第一类型子载波(即通感一体化子载波)和第二类型子载波(即纯通信子载波)的功率比例。
在实施例中，基站分配的频域资源包括通感一体化子载波和纯通信子载波。在一个OFDM符号时间内，每个通感一体化子载波的功率相同，或者这些通感一体化子载波的功率方差小于预设功率方差门限值，即通感一体化子载波和纯通信子载波的功率不同。基站在每次资源调度的情况下，如果基站为UE分配的资源包括通感一体化子载波且UE所采样的调制方式QAM调制(如16QAM，64QAM，256QAM等)时，基站则采用专用或公共信令的信令向UE通知通感一体化子载波集合(即第一类型子载波集合)及该集合中第一类型子载波的功 率与纯通信子载波的功率之间的比例。采用这种方式，由于每个通感一体化子载波的功率相同或者这些子载波的功率方差小于预设功率方差门限值，从而从感知角度可以最大化感知信号的有效相关带宽。另外一方面，通过向UE通知通感一体化子载波集合及相对通信子载波的功率比例，通感一体化子载波可以像传统的通信子载波一样采用QAM方式携带信息，因而可以将感知对通信的负面影响最小化。
在一实施例中，以第一通信节点为基站，第二通信节点为UE，以及功率参数为功率方差为例，并且，第一类型子载波和第二类型子载波之间的功率比例恒定，以及UE采用16QAM调制方式。图9是本申请实施例提供的一种16QAM调制方式的调制示意图。
在实施例中，基站分配的频域资源包括通感一体化子载波(即第一类型子载波)和纯通信子载波(即第二类型子载波)，并且通感一体化子载波之间的功率比例恒定，或者这些子载波的功率方差小于预设功率方差门限值。可以理解为，通感一体化子载波的功率与纯通信子载波的功率不同。为降低对通信性能的影响，在QAM调制中，通感一体化子载波携带通信信息时只占用前两个比特，规定其它比特为预设值(比如，预设值为1)，从而使其调制方式等效于QPSK。以图9为例进行说明，调制方式为16QAM，基站采用第一类型子载波携带通信信息时占用前两个比特，规定后两位为11，即：通感一体化子载波在携带信息时，其调制对应的星座点为图中索引为3,7，11,15这四个星座点中的1个，等效于QPSK调制方式。对于其它QAM方式原理相同，这里不再赘述。
采用这种方式，在最大化感知信号有效相关带宽的同时，还可以将感知对通信的负面影响最小化。与上述将第一类型子载波和第二类型子载波之间的功率比例的实施例相比，该方式不需要专门信令向UE通知通感一体化子载波和纯通信子载波的功率比例。
在一实施例中，以第一通信节点为基站，第二通信节点为UE为例，对基站 为第一类型信号分配目标符号的过程进行说明。其中，第一类型信号指的是用于感知的信号，即感知信号。
在实施例中，基站可以将特殊子帧S中DwPTS的后K个符号用于感知，K小于或等于DwPTS所包含的符号数。
图10a是本申请实施例提供的一种目标符号的分配示意图。如图10a所示，示出了感知信号通过DwPTS最后两个符号进行发送。其中，D表示下行子帧，S表示上行子帧，U表示上行子帧。对于基于LTE TDD的通感一体化系统，感知信号在特殊子帧S中DwPTS的最后K个符号发送，K>＝1。图10b是本申请实施例提供的另一种目标符号的分配示意图。如图10b所示，示出了感知信号通过一个时隙下行符号中最后两个符号进行发送。其中，GP表示保护周期。对于基于NR TDD的通感一体化系统，感知信号在有下行/上行切换的时隙发送，并且，感知信号在该时隙下行符号部分的最后K个符号发送，K>＝1。
采用上述方式，感知信号接收机可以利用特殊子帧的保护周期(GP)来接收目标回波信号，该方法拓展了保护周期的作用，降低了感知信号的开销，同时，也不会对保护周期在通信信号的作用造成影响。
