由于一个终端设备中存在多个通信系统时,不同通信系统的通信频段相邻时,一个通信系统的发送操作会对另一个系统的接收操作造成干扰,产生设备内共存干扰问题。随着无线通信系统的带宽增加以及带宽的不断丰富,现有技术中的IDC消息已经不能解决所有场景下的设备内共存干扰的问题,影响终端设备数据传输的可靠性。

例如,Wi-Fi 2.4GHz、BT与B40/n40、B7/n7和B41/n41、5GHz与n77、n79等邻频互扰,即终端设备在多个通信系统中的工作频率相邻或相近,由于调频信号含有无穷多个边频分量,当其中某些边频分量落入邻道接收机的工作频带内,就会造成邻频互扰;Wi-Fi2.4GHz、5GHz、BT受B1/n1、B5/n5和B41/n41等谐波干扰,即终端设备在某个通信系统中产生的信号的二次谐波、三次谐波等落入邻道接收机的工作频带内,就会造成谐波干扰;Wi-Fi 5GHz与授权频谱辅助接入(license assisted access,LAA)/非授权频谱上的LTE(LTE in unlicensed spectrum,LTE-U)/增强型授权辅助接入(enhanced licensed assisted access,eLAA)之间的同频段共存;Wi-Fi双频、BT并发和单元多频并发之间的交调互扰,即终端设备在工作频率不同的多个通信系统中产生的不同频率信号作用于一非线性电路时,将互相调制,产生新频率信号输出,如果该频率正好落在接收机工作信道频带内,则对接收机构成干扰。
为此,本申请提供了一种通信的方法,能够有效避免设备内共存干扰,提高数据传输的可靠性。
为了便于描述,本申请实施例以蜂窝通信系统和WIFI通信系统为互相干扰的通信系统为例进行说明,其中,第一通信系统为蜂窝通信系统,第二通信系统为WIFI通信系统,但本申请实施例对比并不作限定。
图3示出了本申请实施例提供的通信的方法300。下面将结合图3详细说明方法300中的各个步骤。
应理解,在本申请实施例中,以终端设备和网络设备作为执行方法300的执行主体为例,对方法300进行说明。作为示例而非限定,执行方法300的执行主体也可以是应用于终端设备的芯片和应用于网络设备的芯片。

可选地,该第一IDC干扰调整信息还可以为WIFI通信系统中未干扰该终端设备在蜂窝通信系统中的起止频率,或者频点和带宽。
例如,终端设备在WIFI通信系统的工作频率为100MHz,工作带宽为200MHz,WIFI通信系统发送的信号为干扰源时,终端设备通过内部硬件测量确定该第一IDC干扰调整信息。比如,终端设备在WIFI通信系统中遍历WIFI通信系统的每一个频点和带宽发送测量信号,若终端设备在WIFI通信系统中接收测量信号的灵敏度降低,则表明该终端设备在WIFI通信系统中被蜂窝通信系统干扰,此时终端设备在WIFI通信系统中发送测量信号的频点和带宽为被蜂窝通信系统干扰的频点和带宽;若终端设备在WIFI通信系统中接收测量信号的灵敏度未降低,则表明该终端设备在WIFI通信系统中未被蜂窝通信系统干扰,此时终端设备在WIFI通信系统中发送测量信号的频点和带宽为未被蜂窝通信系统干扰的频点和带宽。通过测量,该WIFI通信系统干扰终端设备在同时工作的蜂窝通信系统中的频点为50MHz,干扰的起始频率为30MHz,干扰的终止频率为70MHz,则该WIFI通信系统干扰终端设备在蜂窝通信系统中的带宽为40MHz,则终端设备确定的第一IDC干扰调整信息为该WIFI通信系统频率干扰该终端设备在蜂窝通信系统中的起始频率30MHz和终止频率70MHz,或者该第一IDC干扰调整信息为WIFI通信系统干扰该终端设备在蜂窝通信系统中的频点50MHz和带宽40MHz。或者,该第一IDC干扰调整信息为WIFI通信系统未干扰该终端设备在蜂窝通信系统中的起始频率0MHz和终止频率30MHz,或者未干扰的起始频率70MHz和终止频率200MHz。或者,该第一IDC干扰调整信息为WIFI通信系统未干扰该终端设备在蜂窝通信系统中的频点10MHz和带宽20MHz,以及未干扰的频点135MHz和带宽130MHz。
可选地,当该蜂窝通信系统为被干扰源时,该终端设备确定该第一IDC干扰调整信息为该终端设备在WIFI通信系统中的工作频点以及带宽,或者该第一IDC干扰调整信息为该终端设备在WIFI通信系统中的工作起止频率。
例如,终端设备中的蜂窝通信系统为被干扰源,在通信过程中,受到同处一个终端设备中WIFI通信系统的干扰,终端设备在蜂窝通信系统中接收数据受到影响。若该终端设备在WIFI通信系统中的工作频点为150MHz,工作起始频率为100MHz,终止频率为200MHz,则该第一IDC干扰调整信息为该终端设备在WIFI通信系统中的工作频点 150MHz和带宽100MHz,或者,该第一IDC干扰调整信息为该终端设备在WIFI通信系统中的工作起始频率100MHz以及终止频率200MHz。
上述技术方案中,终端设备确定的第一IDC干扰调整信息包括频率带宽信息,即频带信息,可以准确确定该IDC干扰范围,从而有效进行IDC干扰调整。

需要说明的是,终端设备中的通信系统可以是一个或多个,而该一个或多个第一通信系统可以为相同的通信系统,也可以为不同的通信系统,本申请实施例对此不作限定。
当终端设备内共存多个通信系统时,由于多个通信系统使用的频段范围有限,设备内共存的多个通信系统之间存在干扰。为了避免干扰造成的系统吞吐量降低,终端设备通过测量确定第一IDC干扰调整信息,其中,该第一IDC干扰调整信息用于指示网络设备进行IDC干扰调整,从而避免终端设备中的多个通信系统间的干扰,提高数据传输的可靠性。
S320,终端设备向网络设备发送该第一IDC干扰调整信息。
终端设备在确定该第一IDC干扰调整信息后,向网络设备发送该第一IDC干扰调整信息,指示该网络设备进行IDC干扰调整。

可选地,该网络设备接收到终端设备发送的第一IDC干扰调整信息后,根据该第一IDC干扰调整信息包括的频率带宽信息进行IDC干扰调整,减小IDC干扰,提高数据传输的可靠性。

可选地,该网络设备根据该第一IDC干扰中包括的频率带宽信息,计算出通信系统之间的干扰大小,从而能根据该干扰大小适当降低该终端设备在蜂窝通信系统中的发射功率,减小IDC干扰,提高数据传输的可靠性。
可选地,该网络设备根据该第一IDC干扰调整信息中包括的频带信息确定该终端设备的第二通信系统被该终端设备在该第一通信系统中干扰的频带与该终端设备在第二通信系统中的工作频带重叠的大小或者间隔大小确定该终端设备在第一通信系统中的发射功率的降低幅度,其中,该重叠越大或者间隔越小,发射功率降低幅度越大,重叠越小或者间隔越大,发射功率降低幅度越小。
例如,蜂窝通信系统作为干扰源时,终端设备在WIFI通信系统中的工作频点为100MHz,带宽为200MHz。场景一中,终端设备在WIFI通信系统中被蜂窝通信系统干扰的工作频点为150MHz和带宽为100MHz;场景二中,终端设备在WIFI通信系统中被蜂窝通信系统干扰的工作频点为150MHz和带宽为50MHz。通过比较,场景二中蜂窝通信系统对终端设备在WIFI通信系统中的干扰频带与终端设备在WIFI通信系统中的工作频带的重叠小于场景一中蜂窝通信系统对终端设备在WIFI通信系统中的干扰频带与终端设备在WIFI通信系统中的工作频带的重叠,即蜂窝通信系统在场景二中对终端设备在WIFI通信系统中的干扰影响小于场景一中对终端设备在WIFI通信系统中的干扰,因此,场景二中终端设备在蜂窝通信系统中的发射功率降低幅度小于场景一中终端设备在蜂窝通信系统中的发射功率降低幅度,即重叠越大,干扰影响程度越大,终端设备在第一通信系统中的发射功率降低幅度越大。
另外,蜂窝通信系统作为干扰源时,终端设备在蜂窝通信系统中的工作频点为100MHz,带宽为200MHz。场景一中,终端设备在WIFI通信系统中的的工作频点为300MHz和带宽为200MHz;场景二中,终端设备在WIFI通信系统中的工作频点为350MHz和带宽为200MHz。通过比较,场景二中终端设备在蜂窝通信系统中的工作频带与终端设备在WIFI通信系统中的工作频带间隔大于场景一中终端设备在蜂窝通信系统中的工作频带与终端设备在WIFI通信系统中的工作频带间隔,因此,相较于场景二,场景一中终端设备在蜂窝通信系统中与终端设备在WIFI通信系统中更易互相造成邻频干扰,因此,场景二中终端设备在蜂窝通信系统中的发射功率降低幅度小于场景一中终端设备在蜂窝通信系统中的发射功率降低幅度,即间隔越小,邻频干扰影响程度越大,终端设备在蜂窝通信系统中的发射功率降低幅度越大。
可选地,当第一通信系统为干扰源时,该网络设备根据该第一IDC干扰调整信息将该 终端设备在该第一通信系统中的接收频点和带宽,或者起止频率切换至不被该第二通信系统干扰的频点和带宽,或者起止频率;或该网络设备根据该第一IDC干扰调整信息将针对该终端设备的该第一通信系统的发射频点和带宽,或者起止频率切换至不被该第二通信系统干扰的频点和带宽,或者起止频率;或该网络设备根据该第一IDC干扰调整信息将该终端设备在该第一通信系统中的下行BWP切换至不被该第二通信系统的干扰的接收频点和带宽,或者起止频率。
例如,终端设备在蜂窝通信系统中的工作频点为100MHz,工作带宽为200MHz,第一IDC干扰调整信息中包括WIFI通信系统干扰终端设备在蜂窝通信系统中的频点为50MHz和带宽为40MHz,或者WIFI通信系统干扰终端设备在蜂窝通信系统中的起始频率为30MHz,终止频率为70MHz。则该网络设备根据该第一IDC干扰调整信息将该终端设备在蜂窝通信系统中的频点和带宽调整到未被WIFI通信系统干扰的频点和带宽,或者将该终端设备在蜂窝通信系统中的起止频点调整到未被WIFI通信系统干扰的起止频点。比如,网络设备将该终端设备在蜂窝通信系统中的工作频点调整到200MHz,带宽不变,或者将该终端设备在蜂窝通信系统中的工作起始频率调整到100MHz,终止频率调整到300MHz。或者,缩小网络设备为终端设备在蜂窝通信系统中分配的工作带宽,即将该终端设备在WIFI通信系统中的工作带宽由原来的200MHz调整到130MHz,工作频点由100MHz调整到135MHz,使得该终端设备在蜂窝通信系统中不被WIFI通信系统干扰,能够正常进行数据接收。
可选地,该网络设备根据该第一IDC干扰中包括的频率带宽信息,计算出通信系统之间的干扰大小,从而能根据该干扰大小适当增加网络设备的发射功率,减小IDC干扰,提高数据传输的可靠性。
可选地,该网络设备根据该第一IDC干扰调整信息中包括的频带信息确定该终端设备的第二通信系统干扰该终端设备在该第一通信系统的频带与该终端设备在第一通信系统中的工作频带重叠的大小或者间隔大小确定该网络设备在第一通信系统中的发射功率的增加幅度,其中,该重叠越大或者间隔越近,发射功率增加幅度越大,重叠越小或者间隔越远,发射功率增加幅度越小。例如,蜂窝通信系统作为被干扰源时,终端设备在蜂窝通信系统中的工作频点为100MHz,带宽为200MHz。场景一中,终端设备在蜂窝通信系统中被WIFI通信系统干扰的工作频点为150MHz和带宽为100MHz;场景二中,终端设备在蜂窝通信系统中被WIFI通信系统干扰的工作频点为150MHz和带宽为50MHz。通过比较,场景二中WIFI通信系统对终端设备在蜂窝通信系统中的干扰频带与终端设备在蜂窝通信系统中的工作频带的重叠小于场景一中WIFI通信系统对终端设备在蜂窝通信系统中的干扰频带与终端设备在蜂窝通信系统中的工作频带的重叠,即WIFI通信系统在场景二中对终端设备在蜂窝通信系统中的干扰影响小于场景一中对终端设备在蜂窝通信系统中的干扰,因此,场景二中网络设备在蜂窝通信系统中的发射功率增加幅度小于场景一中网络设备在蜂窝通信系统中的发射功率增加幅度,即重叠越大,干扰影响程度越大,网络设备在第一通信系统中的发射功率增加幅度越大。
另外,蜂窝通信系统作为被干扰源时,终端设备在蜂窝通信系统中的工作频点为100MHz,带宽为200MHz。场景一中,终端设备在WIFI通信系统中的的工作频点为300MHz和带宽为200MHz;场景二中,终端设备在WIFI通信系统中的工作频点为350MHz和带宽为200MHz。通过比较,场景二中终端设备在蜂窝通信系统中的工作频带与终端设 备在WIFI通信系统中的工作频带间隔大于场景一中终端设备在蜂窝通信系统中的工作频带与终端设备在WIFI通信系统中的工作频带间隔。因此,相较于场景二,场景一中终端设备在蜂窝通信系统中与终端设备在WIFI通信系统中更易互相造成邻频干扰,因此,场景二中网络设备在蜂窝通信系统中的发射功率增加幅度小于场景一中网络设备在蜂窝通信系统中的发射功率增加幅度,即间隔越小,邻频干扰影响程度越大,网络设备在蜂窝通信系统中的发射功率增加幅度越大。

图4示出了本申请实施例提供的通信的方法400。下面将结合图4详细说明方法400中的各个步骤。
应理解,在本申请实施例中,以终端设备和网络设备作为执行方法400的执行主体为例,对方法400进行说明。作为示例而非限定,执行方法400的执行主体也可以是应用于终端设备的芯片和应用于网络设备的芯片。
S410,终端设备确定第二设备内共存IDC干扰调整信息。
实际中,终端设备自身的干扰可能只影响某一根固定天线,比如历史产品下天线隔离度差,主频工作时,三次谐波过大,B5/8/20/26工作时会对WIFI 2.4G频段造成干扰,需要在这些频段工作时,发射天线切换至上天线。
在进行发射天线切换之前,该终端设备需要确定包括天线干扰调整信息的第二IDC干扰调整信息。目前协议中,天线选择基站一般会配置两个码本(codebook)的上行参考信号资源(sounding reference signal resource,SRS resource),每个SRS resource对应不同的天线。例如,SRS resource1对应天线#1,SRS resource1对应天线#2等。
在手机初始接入时,网络设备可以配置多个SRS资源,让终端设备进行SRS轮发,每个SRS资源对应不同的天线端口(port),每个天线端口可以映射到对应的物理天线。然后网络设备通过下行控制信号(downlink control information,DCI)里的上行参考信号资源号(SRS resource indicater,SRI)指示终端设备发送物理上行链路共享通道(physical uplink shared channel,PUSCH)采用哪一个SRS resource,即网络设备通过DCI指示终端设备使用哪一根天线为发射天线。
当终端设备内共存干扰时,终端设备确定第二IDC干扰调整信息,其中,该第二IDC干扰调整信息包括受到干扰的天线对应的SRS资源号(SRS resource index),或者为不被干扰的天线对应的SRS资源号。
可选地,若协议中可以明确指示天线端口号,则该第二IDC干扰调整信息中可以直接包括受干扰的天线端口号,或不受干扰的天线端口号。

S430,网络设备根据该第二IDC干扰调整信息确定发射天线。
网络设备接收到该终端设备发送的第二IDC干扰调整信息,根据该第二IDC干扰调 整信息确定发射天线。
例如,该第二IDC干扰调整信息包括被干扰的天线对应的SRS资源号,该网络设备根据该SRS资源号与天线的对应关系,确定受干扰的天线。
或者,该第二IDC干扰调整信息包括未被干扰的天线对应的SRS资源号,该网络设备根据该SRS资源号与天线的对应关系,确定未受干扰的天线。
或者,该第二IDC干扰调整信息可以包括天线端口号,网络设备根据该第二IDC干扰调整信息中包括的被干扰的天线端口号确定被干扰的天线,或者,该网络设备根据该第二IDC干扰调整信息中包括的未被干扰的天线端口号确定未被干扰的天线。
图5示出了发射天线与接收天线的对应关系。如图5所示,在手机初始接入时,终端设备进行SRS轮发。当1根发射天线对应2根接收天线时,即终端设备发射的SRS可以被2根接收天线接收,终端设备确定受到干扰的天线对应的SRS资源号为SRS_1,并将该受干扰的天线对应的SRS资源号SRS_1作为第二IDC干扰调整信息发送给网络设备,网络设备根据该终端设备发送的第二IDC干扰调整信息,确定该终端设备的发射天线为SRS_0对应的天线;或者终端设备确定受到干扰的天线端口为端口1,并将该受干扰天线的端口(即,端口1)作为第二IDC干扰调整信息发送给网络设备,网络设备根据该终端设备发送的第二IDC干扰调整信息,确定该终端设备的发射天线为端口0对应的天线;当2根发射天线对应4根接收天线时,即终端设备发射的SRS可以被4根接收天线接收,终端设备确定受到干扰的天线对应的SRS资源号为SRS_2和SRS_3,并将该受干扰的天线对应的SRS资源号SRS_2和SRS_3作为第二IDC干扰调整信息发送给网络设备,网络设备根据该终端设备发送的第二IDC干扰调整信息,确定该终端设备的发射天线为SRS_0和SRS_1对应的天线;或者终端设备确定受到干扰的天线端口为端口2和端口3,并将该受干扰天线的端口(即,端口2和端口3)作为第二IDC干扰调整信息发送给网络设备,网络设备根据该终端设备发送的第二IDC干扰调整信息,确定该终端设备的发射天线为端口0和端口1对应的天线。
上述技术方案中,网络设备通过接收终端设备发送的第二IDC干扰调整信息,并根据该第二IDC干扰调整信息确定未受干扰的天线为该终端设备的发射天线,从而减小IDC干扰,提高数据传输的可靠性。
网络设备根据确定的未被干扰的天线,将该未被干扰的天线作为发射天线,或者根据上行天线调度PUSCH在非干扰天线端口发射。
本申请实施例中,终端设备通过确定包括未被干扰的天线信息或被干扰的天线信息的第二IDC干扰调整信息,将确定的第二IDC干扰调整信息发送至网络设备,该网络设备根据接收到的第二IDC干扰调整信息,将未被干扰的天线作为发射天线,不再需要进过FDM或TDM方式避免干扰,而是直接通过确定未被干扰的天线来避免IDC干扰,提高了数据传输的可靠性。
