结合前面的描述，如图2所示，为本申请实施例提供的一种通信方法流程示意图。参见图2，该方法包括：
步骤201：第一网络设备在第一载波上向第一终端设备发送第一信号。
所述第一载波为所述第一无线通信技术和第二无线通信技术共享的载波；所述第一网络设备为所述第一无线通信技术中的网络设备。
需要说明的是，本申请实施例中，对第一信号并不限定，第一信号可以包括数据信息，也可以包括控制命令信息等，本申请实施例对此并不限定。第一信号只需要是满足第一无线通信技术的规定的信号即可。
步骤202：第一终端设备在第一载波上从第一网络设备接收第一信号。
在本实施方式中，第一无线通信技术的第一网络设备能够使用第二无线通信技术的载 波，此处的载波应理解为频率资源，也就是说，第一无线通信技术的网络可以与第二无线通信技术共享相同的频率资源，从而能够提升频率资源的整体使用效率。
可选的，所述第一无线通信技术为蜂窝移动通信技术，例如可以是LTE系统，也可以是NR系统等；所述第二无线通信技术为广播通信技术。也就是说，蜂窝移动通信技术的网络设备与广播通信技术网络共享相同的频率资源。需要说明的是，由于广播通信技术网络中存在门限效应，网络整体频谱效率较低，因此，让蜂窝移动通信技术的网络与广播通信技术网络共享相同的频率资源，能够在不明显影响广播通信技术网络的性能的前提下，为蜂窝移动通信技术网络提供更多的资源，能够最大限度的提升频谱使用效率。
可选的，所述第一网络设备向所述第一终端设备发送第一指示信息。
其中，所述第一指示信息用于指示以下至少一项：
所述第一信号是否存在干扰信号；所述干扰信号与所述第一信号的功率配比；所述干扰信号的调制方式。
相应的，第一终端设备从所述第一网络设备接收第一指示信息，并根据所述第一指示信息解调所述第一信号中携带的信息。
需要说明的是，第一指示信息可以为同时指示出上述三项，也可以包括三个字段，每个字段指示出其中一项，本申请实施例对此并不限定。
针对第一信号是否存在干扰信号，其只包括两个状态，即存在干扰和不存在干扰。需要说明的是，若其指示存在干扰信号，则第一终端设备在接收第一信号时需要将该干扰删除后才能获取第一信号所传输的信息；若其指示不存在干扰信号，则第一终端设备直接按照现有技术的方法接收第一信号。还需要说明的是，此处并不对干扰信号的名称进行限定，应理解，第一指示信息的实质在于为第一终端设备指示辅助信息，以使第一终端设备能够采用合适的接收方法来接收第一信号。干扰信号也可以称为其他信号、冗余信号、共享信号等，或者具体称为第二无线接入技术的信号，如广播信号等，或直接称为信号。
示例性的，本申请实施例中，可以采用至少一个比特位来指示第一信号是否存在干扰信号。例如采用1个比特位时，该比特位取值为0可以表示第一信号不存在干扰信号，该比特位取值为1可以表示第一信号存在干扰信号。当然，也可以反过来，即该比特位取值为1可以表示第一信号不存在干扰信号，该比特位取值为0可以表示第一信号存在干扰信号。
再例如，采用2个比特位来指示第一信号是否存在干扰信号时，该2个比特位取值为00可以表示第一信号不存在干扰信号，该2个比特位取值为11可以表示第一信号存在干扰信号。当然，以上只是示例，还可以用其它值来表示第一信号是否存在干扰信号，本申请实施例对此并不限定，在此不再赘述。
针对干扰信号与第一信号的功率配比，由于干扰信号与第一信号通过功率分配的方式复用在一起，通常干扰信号的功率较大，第一信号的功率较小，因此当第一终端获取了干扰信号与第一信号的功率配比后，可以根据功率配比确定出第一信号，提升通信性能。本实施例并不限定干扰信号的功率相比于第一信号的功率较大，也可以反过来。
第一指示信息所指示的干扰信号与第一信号的功率配比可以有多种表现形式，例如，功率配比可以是干扰信号的功率比第一信号的功率，也可以是第一信号的功率比干扰信号的功率，还可以是干扰信号的功率比上干扰信号的功率与第一信号的功率之和，又可以是第一信号的功率比上干扰信号的功率与第一信号的功率之和，还可以是干扰信号的功率与 第一信号的功率之和比第一信号的功率，还可以是干扰信号的功率与第一信号的功率之和比干扰信号的功率。需要说明的是，上述功率配比的表现形式只为举例，本实施例并不限定，其他与功率配比等价的形式也属于本发明的保护范围。例如，干扰信号与第一信号的功率配比等于x/y，则第一指示信息指示的为sqrt(x/y),其中sqrt(a)表示a的平方根(正数)。
示例性的，功率配比的形式是干扰信号的功率比第一信号的功率时，该功率配比数值可以是1:3、1:1、3:2等。需要说明的是，功率配比的形式不限于x：y的形式，还可以是x/y的形式，也可以是小数的形式，如z＝x/y，也就是第一指示信息指示的功率配比值为z。例如，干扰信号的功率比第一信号的功率为1:3时，z的取值可以是0.33；干扰信号的功率比第一信号的功率为1:1时，z的取值可以是1；干扰信号的功率比第一信号的功率为3:2时，z的取值可以是1.5等，其它情况在此不再赘述。
示例性的，功率配比的形式是第一信号的功率比干扰信号的功率时，该功率配比数值可以是2:5、1:1、1:2等。需要说明的是，功率配比的形式不限于x：y的形式，还可以是x/y的形式，也可以是小数的形式，如z＝x/y，也就是第一指示信息指示的功率配比值为z。例如，第一信号的功率比干扰信号的功率为2:5时，z的取值可以是0.4；第一信号的功率比干扰信号的功率为1:1时，z的取值可以是1；第一信号的功率比干扰信号的功率为1:2时，z的取值可以是0.5等，其它情况在此不再赘述。
示例性的，功率配比的形式为第一信号的功率比上干扰信号的功率与第一信号的功率之和，该功率配比数值可以是1:3、1:4、1:5等。例如，1:3表示第一信号的功率为1份，第一信号的功率与干扰信号的功率之和为3份，从而干扰信号的功率为2份。需要说明的是，功率配比的形式不限于x：y的形式，还可以是x/y的形式，也可以是小数的形式，如z＝x/y，也就是第一指示信息指示的功率配比值为z，z的取值可以是0.33、0.25、0.2等，此处并不限定。
示例性的，功率配比的形式为干扰信号的功率比上干扰信号的功率与第一信号的功率之和，该功率配比数值可以是1:3、2:3、3:5等。例如，1:3表示干扰信号的功率为1份，第一信号的功率与干扰信号的功率之和为3份，从而第一信号的功率为2份。需要说明的是，功率配比的形式不限于x：y的形式，还可以是x/y的形式，也可以是小数的形式，如z＝x/y，也就是第一指示信息指示的功率配比值为z。干扰信号的功率比上干扰信号的功率与第一信号的功率之和分别是1:3、2:3、3:5时，z的取值分别可以是0.33、0.67、0.6等，此处并不限定。
示例性的，功率配比的形式是干扰信号的功率与第一信号的功率之和比第一信号的功率，该功率配比数值可以是3:1、3:2、5:2等。例如，5:2表示第一信号的功率为2份，干扰信号的功率与第一信号的功率之和为5份，从而干扰信号的功率为3份。需要说明的是，功率配比的形式不限于x：y的形式，还可以是x/y的形式，也可以是小数的形式，如z＝x/y，也就是第一指示信息指示的功率配比值为z，例如，干扰信号的功率与第一信号的功率之和比第一信号的功率分别是3:1、3:2、5:2时，z的取值可以是3、1.5、2.5等，此处并不限定。
示例性的，功率配比的形式是干扰信号的功率与第一信号的功率之和比干扰信号的功率，该功率配比数值可以是3:2、4:3、5:2等。例如，4:3表示干扰信号的功率为3份，干扰信号的功率与第一信号的功率之和为4份，从而第一信号的功率为1份。需要说明的是， 功率配比的形式不限于x：y的形式，还可以是x/y的形式，也可以是小数的形式，如z＝x/y，也就是第一指示信息指示的功率配比值为z，例如，干扰信号的功率与第一信号的功率之和比干扰信号的功率分别是3:2、4:3、5:2时，z的取值可以是1.5、1.333、2.5等，此处并不限定。
示例性的，功率配比的形式为干扰信号与第一信号的功率配比的索引值。例如，功率配比数值是1:3、1:4、1:5时，对应的索引值为00、01和10。当功率配比的索引值为00时，表示干扰信号与第一信号的功率配比为1:3；当功率配比的索引值为01时，表示扰信号与第一信号的功率配比为1:4；当功率配比的索引值为10时，表示干扰信号与第一信号的功率配比为1:5。
示例性的，第一网络设备和第一终端设备可以预先约定至少一个功率配比，如2:1、3:1及4:1等，此处并不限定，则第一指示信息可以用于指示所述至少一个功率配比中的一个，第一终端设备从而可以确定干扰信号与第一信号的功率配比。本实施例并不限定至少一个功率配比的个数，可以是2个、3个、4个，或其他正整数个。示例性的，功率配比的个数为4个，如下表1所示，则第一指示信息可以指示4个状态，每个状态分别对应一个功率配比值，具体的，状态0对应第1功率配比值，状态1对应第2功率配比值，以此类推。当第一终端设备从第一网络设备接收到第一指示信息后，第一终端设备可以根据第一指示信息所指示的状态确定该状态对应的功率配比值。
表1
状态 功率配比
0 第1功率配比值
1 第2功率配比值
2 第3功率配比值
3 第4功率配比值
当然，表1只是示例，还可能存在其他形式的表格，在此不再逐一举例说明。
针对干扰信号的调制方式，第一终端获知干扰信号的调制方式后，其可以相应的解调方式获取第一信号，提升通信性能。
通常，调制方式有正交相移键控(quadrature phase shift keying，QPSK)、16正交幅度调制(quadrature amplitude modulation，QAM)、64QAM、256QAM等，第一网络设备与第一终端设备可以预先约定至少一个调制方式，则第一指示信息可以用于指示所述至少一个调制方式中的一个，第一终端设备从而可以确定干扰信号的调制方式。需要说明的是，本实施例并不限定至少一个调制方式的个数，可以是2个、3个、4个，或其他正整数个，在此不再逐一举例说明。
示例性的，本申请实施例中，可以为每个调制方式配置一个索引值，第一指示信息可以指示干扰信号的调制方式的索引值。举例来说，第一网络设备与第一终端设备可以预先约定4个调制方式：QPSK、16QAM、64QAM、256QAM，对应的索引值分别为00、01、10、11，具体可以参考表2所示。
表2
索引值 调制方式
00 QPSK
01 16QAM
10 64QAM
11 256QAM
当网络设备发送的第一指示信息指示的调制方式的索引值为00时，可以指示干扰信号的调制方式为QPSK；当网络设备发送的第一指示信息指示的调制方式的索引值为01时，可以指示干扰信号的调制方式为16QAM；当网络设备发送的第一指示信息指示的调制方式的索引值为10时，可以指示干扰信号的调制方式为64QAM；当网络设备发送的第一指示信息指示的调制方式的索引值为11时，可以指示干扰信号的调制方式为256QAM。当然，以上只是示例，其它情况不再赘述。
当然以上只是示例，第一指示信息还可以指示出第一信号的其他信号特征，本申请实施例对此并不限定，在此不再逐一举例说明。
通过上述方法流程，第一网络设备通过第一指示信息指示在第一载波中发送的第一信号的干扰信号的信号特征，可以使得第一终端设备根据第一指示信息消除干扰信号，从而提高频谱利用率，提升在第一载波中接收信号的可靠性。可选的，第一网络设备可以通过多种方式发送第一指示信息，例如所述第一指示信息可以携带在下行控制信息(Downlink Control Information，DCI)中，也可以携带在无线接入控制(Radio Resource Control，RRC)信令中，还可以携带在媒体接入控制(Medium Access Control，MAC)信令中等，在此不再逐一举例说明。
需要说明的是，第一指示信息可以都携带在一个信令中由第一网络设备发送给第一终端设备，也可以携带在多个不同的信令中由第一网络设备发送给第一终端设备。示例性的，相比于蜂窝移动通信网络，广播通信网络中的业务持续时间较长，因此，对于第一终端设备来说，干扰信号在很长一段时间内都会存在，在这种情况下，是否存在干扰可以携带在RRC或MAC信令中，而功率配比和/或调制方式可以携带在DCI中，这样相比于所有干扰特征都携带在DCI中能够降低开销。又例如，对于某些广播终端较少的广播通信网络，有些时间段内可能所有广播终端都处于关闭状态，此时广播通信网络可以不发送广播信号，从而使得广播信号开关频繁，此时功率配比和调制方式可以携带在RRC或MAC信令中，而是否存在干扰可以携带在DCI中，这样相比于所有干扰特征都携带在DCI中能够降低开销。也就是说，干扰信号特征可以携带在RRC、MAC和DCI信令中的至少两种中，这样能够适应不同场景的不同需求，相比于干扰信号特征只携带在一类信令中更加灵活。
可选的，第一网络设备可以通过载波聚合方式使用第一载波和第二载波向第一终端设备发送信号，即所述第二载波与所述第一载波为载波聚合的两个载波。进一步的，所述第二载波为主载波，所述第一载波为辅载波。需要说明的是，由于蜂窝移动通信网络中的小区通常包括一个下行载波和一个上行载波，而本实施例中的第一载波为与广播通信网络共享的载波，其可以只有下行，因此，第一网络设备可以采用载波聚合的方式来使用第一载波。另外，蜂窝移动通信网络可以定义新一类的小区，即该小区包括两个下行载波和一个上行载波，从而使得蜂窝移动通信网络能够更方便的与广播通信网络共享相同的频率资源。
可选的，所述第一网络设备还可以在第二载波上向所述第一终端设备发送第二信号。
本申请实施例中，第二信号可以包括数据信息，也可以包括控制命令信息等，本申请实施例对此并不限定。第二信号只需要是满足第一无线通信技术的规定的信号即可。
举例来说，如图3所示，第一网络设备所处的通信系统为NR系统，第二网络设备所处的通信系统为广播通信系统。第一网络设备在NR系统中，可以使用一个时分双工(time  division duplex，TDD)载波，载波频率可以是3.5GHz或4.9GHz，并可以使用NR系统与广播通信系统共享的一个下行载波，载波频率可以是700MHz。图3中，D表示下行子帧，U表示上行子帧。
需要说明的是，第一网络设备与第二网络设备可以采用时分复用、频分复用和非正交复用的方式共享第一载波。应理解，时分复用的方式为第一网络设备与第二网络设备在第一载波上的不同时间段上传输信号，例如，第一网络设备可以在每10ms中的第1、3、5、7、9个1ms上传输信号，第二网络设备可以在每10ms中的第2、4、6、8、10个1ms上传输信号，从而第一网络设备与第二网络设备传输的信号互不干扰。频分复用的方式为第一网络设备与第二网络设备在第一载波上的不同频率范围上传输信号，例如，第一网络设备可以在10MHz的第一载波中频率较小的5MHz上传输信号，而第二网络设备可以在10MHz的第一载波中频率较大的5MHz上传输信号，从而第一网络设备与第二网络设备传输的信号互不干扰。非正交复用的方式为第一网络设备与第二网络设备在第一载波上的相同时频资源上传输信号，例如，第一网络设备的信号与第二网络设备发送的信号在功率维度上进行区分，第一网络设备发送的信号功率较小，第二网络设备发送的信号功率较大，此时第一网络设备与第二网络设备传输的信号之间存在干扰。
由于第一载波为共享的载波，在第一载波中发送的第一信号可能存在干扰信号。可选的，所述干扰信号为第二网络设备通过所述第一载波发送的信号，所述第二网络设备为所述第二无线通信技术的网络设备。第一网络设备可以获知干扰信号为第二网络设备发送的信号，但是从第一终端设备的角度，其并不知道干扰信号的来源，因此第一网络设备可以通过第一指示信息，向第一终端设备指示干扰信号的信号特征，使得第一终端设备干扰信号的相关信息，从而消除干扰信号。
结合前面的描述，第一终端设备接收到第一指示信息之后，可以根据第一指示信息确定第一信号是否存在干扰。当第一终端设备确定不存在干扰信号，则第一终端直接按照现有技术的方法接收第一信号；相应的，当第一终端设备确定存在干扰信号，则根据干扰信号的调制方式、干扰信号与第一信号的功率配比将干扰信号删除。
本申请实施例中，第一终端设备还可以在第一载波中接收第二网络设备发送的第三信号，为此第一网络设备需要通过第二指示信息，向第一终端设备指示出第三信号的信号特征，第一终端设备从而可以解调第三信号。需要说明的是，信号特征是指信号的调制方式、编码率等信息的统称，并不具有限定作用。
结合前面的描述，如图4所示，为本申请实施例提供的一种通信方法流程示意图。参见图4，该方法包括：
步骤401：第一网络设备确定数据信息，并将所述数据信息发送给第二网络设备。
其中，所述第一网络设备为第一无线通信技术中的网络设备；所述第二网络设备为第二无线通信技术中的网络设备。
需要说明的是，数据信息为第一无线通信技术的信息，而数据信息的具体内容，本申请实施例对此并不限定。
步骤402：第二网络设备接收来自第一网络设备的数据信息，并在第一载波中向第一终端设备发送携带所述数据信息的第三信号。
本申请实施例中，对第三信号的具体形式并不限定，第三信号只需要是满足第二无线通信技术的规定的信号即可。
可选的，所述第一网络设备向第一终端设备发送第二指示信息。
所述第二指示信息用于指示第三信号的信号特征；所述第三信号为所述第二网络设备在第一载波上向所述第一终端设备发送的、用于承载所述数据信息的信号。
需要说明的是，第一网络设备发送第二指示之前，可以获取第二网络设备发送的第三信号的信号特征，具体如何获取，本申请实施例对此并不限定。举例来说，第二网络设备可以将第三信号的信号特征发给至第一网络设备，例如第二网络设备可以将第三信号的子载波间隔、调制方式、编码率等通知给第一网络设备。或者，第二网络设备与第一网络设备之间可以预先约定第三信号的子载波间隔、调制方式、编码率等信息，在此不再赘述。
可选的，第一终端设备从第一网络设备接收第二指示信息。
可选的，第一终端设备在第一载波上从第二网络设备接收所述第三信号，并根据所述第二指示信息解调所述第三信号中的数据信息。
通过上述方法流程，第一网络设备通过第二指示信息指示在第一载波中发送的第三信号的信号特征，可以使得第一终端设备根据第二指示信息在一载波中接收第三信号，从而提高频谱利用率，提升在第一载波中接收信号的可靠性。
可选的，所述第一无线通信技术为蜂窝移动通信技术，例如可以是LTE系统，也可以是NR系统等；所述第二无线通信技术为广播通信技术。
可选的，第一网络设备可以通过多种方式发送第二指示信息，例如所述第二指示信息可以携带在DCI中，也可以携带在RRC信令中，还可以携带在MAC信令中等，另外，第二指示信息指示第三信号的信号特征也可以携带在RRC、MAC和DCI信令中的至少两种中，这样能够适应不同场景的不同需求，相比于信号特征只携带在一类信令中更加灵活，在此不再逐一举例说明。
可选的，第一网络设备可以通过载波聚合方式使用第一载波和第二载波向第一终端设备发送信号，即所述第二载波与所述第一载波为载波聚合的两个载波。进一步的，所述第二载波为主载波，所述第一载波为辅载波。需要说明的是，由于蜂窝移动通信网络中的小区通常包括一个下行载波和一个上行载波，而本申请实施例中的第一载波为与广播通信网络共享的载波，其可以只有下行，因此，第一网络设备可以采用载波聚合的方式来使用第一载波。另外，蜂窝移动通信网络可以定义新一类的小区，即该小区包括两个下行载波和一个上行载波，从而使得蜂窝移动通信网络能够更方便的与广播通信网络共享相同的频率资源。
可选的，所述第一终端设备也可以通过第二载波接收第一网络设备发送的第四信号，且所述第三信号与所述第四信号联合编码。本申请实施例中，第思信号只需要是满足第一无线通信技术的规定的信号即可，本申请实施例对第四信号中包括的是数据信息还是控制命令信息并不限定。
可选的，所述第二指示信息用于指示以下至少一项：
所述第三信号的子载波间隔；所述第三信号的调制方式；所述第三信号的编码率；所述数据信息在所述第三信号中的比特位置。
当然以上只是示例，第二指示信息还可以指示出其他内容，在此不再逐一举例说明。
针对第三信号的子载波间隔，可以为15kHz，可以为30kHz等，具体根据实际情况确定。本申请实施例中，第二指示信息可以直接指示出第三信号的子载波间隔，例如，第三信号的子载波间隔为15kHz，第二指示信息指示出的值为15；第三信号的子载波间隔为 30kHz，第二指示信息指示出的值为30。
本申请实施例中，第二指示信息可以间接指示出第三信号的子载波间隔。示例性的，本申请实施例中，第一网络设备与第一终端设备可以预先约定至少一个子载波间隔，则第二指示信息可以用于指示所述至少一个子载波间隔中的一个，第一终端设备从而可以确定第三信号的子载波间隔。需要说明的是，本实施例并不限定至少一个子载波间隔的数量，可以是1个，也可以大于1个，在此不再逐一举例说明。
示例性的，本申请实施例中，还可以为每个子载波间隔配置一个索引值，第二指示信息可以指示子载波间隔的索引值。举例来说，第一网络设备与第一终端设备可以预先约定3个子载波间隔：15kHz、30kHz、60kHz，对应的索引值分别为01、10、11，具体可以参考表3所示。
表3
索引值 子载波间隔
01 15kHz
10 30kHz
11 60kHz
当网络设备发送的第二指示信息指示的子载波间隔的索引值为01时，指示的子载波间隔为15kHz；当网络设备发送的第二指示信息指示的子载波间隔的索引值为10时，指示的子载波间隔为30kHz；当网络设备发送的第二指示信息指示的子载波间隔的索引值为11时，指示的子载波间隔为60kHz。当然，以上只是示例，其它情况不再赘述。
需要说明的是，目前的标准中，子载波间隔不是任意值，而是需要满足公式：15*2 MkHz，M为大于0的整数。因此，示例性的，本申请实施例中，第二指示信息还可以指示子载波间隔对应的M的取值。举例来说，当网络设备发送的第二指示信息指示的值为0时，指示的子载波间隔为15kHz；当网络设备发送的第二指示信息指示的值为1时，指示的子载波间隔为30kHz；当网络设备发送的第二指示信息指示的值为2时，指示的子载波间隔为60kHz。当然，以上只是示例，其它情况不再赘述。

需要说明的是，本实施例并不限定至少一个调制方式的个数，可以是1个，也可以是大于1个的任意正整数个，在此不再逐一举例说明。
示例性的，本申请实施例中，可以为每个调制方式配置一个索引值，第二指示信息可以指示干扰信号的调制方式的索引值。举例来说，第一网络设备与第一终端设备可以预先约定4个调制方式：QPSK、16QAM、64QAM、256QAM，对应的索引值分别为00、01、10、11，具体可以参考表4所示。
