为便于更好的理解本申请实施例，首先对相关的技术作一说明。
在无线通信中，调制是完成信号频谱搬移的主要方法。例如，如图2所示，可以通过混频器将低频输入信号F1跟调制载波F0进行非线性操作产生两个信号的和频率信号或差频率信号，从中筛选出需要的高阶频率输出信号F2，即完成了从低频到高频的频谱搬移，其中，频率关系为F2＝F1+F0。
对于宽带信号来说，其中心频点称为直流载波位置，也称DC(Direct Current)位置，如图3中的F1及F2。
在具体实现中，信号的调制是在终端设备的射频芯片(RFIC)中实现的，如图4所示，终端设备的基带芯片(BBIC)将基带信号输入至RFIC，进一步地，在RFIC中，输入的低频基带信号和该RFIC的本振信号(LO，频率为F0)，混频产生射频信号，经过功率放大器(PA)放大后，最后通过该终端设备的天线发射出去。
在正交频分复用(Orthogonal frequency-division multiplexing，OFDM)调制方式中，通常DC位置会有比较强的信号干扰，在接收端中需要将这个载波去掉以提高接收信噪 比，因此接收端需要知道准确的DC位置。该DC位置通常由发射端告知接收端。以上行为例，终端设备需要告知网络设备其发射信号的准确的DC位置，便于网络设备准确的将DC位置的子载波去掉。
在NR系统中，为了终端的省电，引入了BWP的概念，网络设备通常会给终端设备配置一个较小的发射和接收带宽，从而减少终端设备发射和接收信号的复杂度。例如在整个频段内会有多个信道，终端设备接入一个信道后，网络设备会进一步配置不超过4个BWP(在同一时间只能激活一个BWP)，终端设备在后续的通信中将在这个激活的BWP中工作。终端设备可以基于配置的BWP进行DC位置的上报，假设单载波上配置有4个BWP，则终端设备最多上报4个DC位置给网络设备。
在一些场景中，终端设备可以工作在多个载波上，每个载波又可以配置多个BWP，每两个BWP可以确定一个DC位置，则潜在的DC位置非常多，如图5所示，载波1配置有BWP1～BWP4，载波2上配置有BWPx～BWPz，……，载波n上配置有BWPa～BWPd，则潜在的BWP组合有4*3*…*4种，在配置的载波数较多的情况下，潜在的BWP组合的数量会非常庞大，此情况下，如何进行DC位置的上报是一项急需解决的问题。
图6是根据本申请实施例的上报直流载波位置的方法的示意性交互图，如图6所示，该方法200可以包括如下至少部分步骤：
S202，终端设备根据第一信息，确定至少一个直流载波位置；
S203，所述终端设备向所述网络设备上报所述至少一个直流载波位置。

可选地，所述多个载波可以指网络设备配置并且激活的上行载波。
例如，网络设备给终端设备配置了M个载波，进一步地，网络设备激活了该M个载波中的N个载波，则该第一载波集合可以包括该N个载波，其中，N小于M。
在该方式2中，所述终端设备可以根据网络设备配置并且激活的多个载波中的频率最低和频率最高的载波分别对应的BWP配置，确定DC位置。

结合图8和图9举例说明，在图8的示例中，终端设备上配置有载波1～载波4，该4个载波对应单个发射链路，则采用方式1确定DC位置时，可以根据载波1和载波4对应的BWP配置确定DC位置。在图9的示例中，终端设备上配置有载波1～载波4，其中，载波1和载波2对应发射链路1，载波3和载波4对应发射链路2，则采用方式1确定DC位置时，可以根据载波1和载波2对应的BWP配置确定发射链路1对应的DC位置，根据载波3和载波4对应的BWP配置确定发射链路2对应的DC位置。

作为另一示例，所述终端设备可以根据所述第一载波上的特定BWP配置和所述第二载波上的特定BWP配置确定DC位置。
可选地，所述第一载波上的特定BWP配置可以指激活的BWP配置，或者频点最低的BWP配置，所述第二载波上的特定BWP配置可以指激活的BWP配置，或者频点最高的BWP配置。
方式4

在该方式4中，所述终端设备可以根据网络设备配置并且激活的上行载波和下行载波中的频率最低和频率最高的载波对应的BWP配置，确定DC位置。
在该方式4中，所述第一载波为网络设备配置并且激活的上行载波和下行载波中的频率最低的载波，所述第二载波为网络设备配置并且激活的上行载波和下行载波中的频率最高的载波。

作为另一示例，所述终端设备可以根据所述第一载波上的激活BWP配置和所述第二BWP上的激活BWP配置确定DC位置。
因此，基于本申请实施例的DC位置的确定方式，将终端设备上报的DC位置与该网络设备配置的多个载波中的具体的载波位置进行了解耦，而只跟频点最低和频点最高的载波有关，有利于降低确定的DC位置的数量，进而降低信令开销。
方式5
在该方式5中，所述终端设备可以根据网络设备的请求信息确定DC位置。
可选地，在一些实施例中，所述终端设备在接收到网络设备的请求信息的情况下，根据所述网络设备的请求信息确定DC位置，在未接收到网络设备的请求信息的情况下，根据前述实施例中的方式确定所述DC位置。
可选地，在一些实施例中，所述请求信息可以是在网络设备激活BWP之前发送，或者也可以是在激活BWP之后发送。
可选地，在一些实施例中，所述终端设备上报DC位置可以是在网络设备激活BWP之前，或者在网络设备激活BWP之后。
可选地，在一些实施例中，所述网络设备的请求信息包括所述网络设备请求所述终端设备进行直流载波位置的上报所针对的载波和/或BWP的标识信息，例如载波号和/或 BWP ID。则所述终端设备可以基于网络设备的请求根据特定的载波或BWP确定DC位置，进一步进行DC位置的上报。
例如，网络设备的请求信息中包括载波1和载波2的索引号，则该终端设备可以根据载波1和载波2分别对应的BWP配置，确定DC位置。具体确定方式参考前述的实现方式。
又例如，网络设备的请求信息中包括BWP1、BWP2、BWPx、BWPa的BWP ID，则终端设备可以基于该四个BWP确定DC位置。
在该方式5中，终端设备基于网络设备请求的载波配置或BWP配置确定DC位置，以及进行DC位置的上报，而不是基于所有载波配置确定DC位置，能够降低信令开销。
综上，终端设备在确定DC位置时，只考虑频点最低和频点最高的载波对应的BWP配置，有利于降低信令开销，进一步地，考虑终端设备的发射链路架构以及上行发射和下行接收是否共用DC位置等因素，对DC位置的确定方式进行适应性调整，使得上报的DC位置更为准确且有效，这样，网络设备基于上报的DC位置能够有效的消除干扰。
