具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
请参考图1，其示出了本公开各个实施例涉及的信号接收系统的框图，该信号接收系统包括基站110和终端120，基站110与终端120之间建立连接。
信号接收系统可以应用于5G(Fifth Generation，第五代通信系统)中。其中，由于5G提出的业务需求包括eMBB、URLLC(Ultra Reliable&Low Latency Communication，超高可靠性与超低时延通信)和mMTC(Massive Machine Type Communication，大规模物联通信)，且URLLC的业务需求对时延要求较高，因此，为eMBB的业务需求所配置的15kHz的子载波间隔已经无法满足URLLC的业务需求，需要为URLLC配置大于15kHz的子载波间隔。
终端120支持eMBB和URLLC的业务需求，由于两种业务需求对应的子载波间隔不同，因此，终端120需要分别为两种业务需求进行系统信号配置，在配置成功后，终端120可以根据两种配置接收基站110发送的信号，从而与基站110进行通信。
由于每种业务需求对应一种系统信号配置，为了便于区分，将两种系统信号配置命名为第一系统信号配置和第二系统信号配置，下文将eMBB的业务需求对应的系统信号配置称为第一系统信号配置，将URLLC的业务需求对应的系统信号配置称为第二系统信号配置；或者，将URLLC的业务需求对应的系统信号配置称为第一系统信号配置，将eMBB的业务需求对应的系统信号配置称为第二系统信号配置。其中，第一系统信号配置中的第一子载波间隔和第二系统信号配置中的第二子载波间隔不同。
图2是根据一示例性实施例示出的一种信号接收方法的流程图，该信号接收方法应用于图1所示的终端120中，如图2所示，该信号接收方法包括以下步骤。
在步骤201中，根据终端支持的频带，确定待接收的信号与第一子载波间 隔对应的第一频域位置和信号与第二子载波间隔对应的第二频域位置，该信号为同步信号或基本广播信号。
同步信号包括PSS(Primary Synchronization Signal，主同步信号)和SSS(SecondarySynchronization Signal，辅同步信号)。终端接收到同步信号后，与基站进行频率和时间同步，以便后续接收基本广播信号。
基本广播信号携带有主要广播信息，或者，基本广播信号携带有主要广播信息和系统信息块。其中，在一种实现中，主要广播信息包括系统带宽、系统帧号和PHICH(Physical Hybrid ARQ Indicator Channel，物理混合自动重传指示信道)配置，系统信息块可按照业务需求进行划分，比如，用于小区无线配置的系统信息块、用于小区重选的系统信息块等等，本实施例不作限定。
第一频域位置是以第一子载波间隔发送信号时信号所在的频域位置，第二频域位置是以第二子载波间隔发送信号时信号所在的频域位置。
在步骤202中，确定在频带内为第一子载波间隔分配的第一频率资源和为第二子载波间隔分配的第二频率资源。
比如，当终端支持1901MHz-2000MHz的频带，且平均分配频率资源时，第一频率资源可以是1901MHz-1950MHz的频带，第二频率资源可以是1951MHz-2000MHz的频带。
在步骤203中，根据第一频域位置在第一频率资源上接收信号，同时，根据第二频域位置在第二频率资源上接收信号。
由于终端并不能确定出信号的时域位置，因此，终端可以根据第一频域位置在第一频率资源上盲搜信号，同时，根据第二频域位置在第二频率资源上盲搜信号。
综上所述，本公开提供的信号接收方法，通过根据终端支持的频带，确定待接收的信号与第一子载波间隔对应的第一频域位置和信号与第二子载波间隔对应的第二频域位置；确定在频带内为第一子载波间隔分配的第一频率资源和为第二子载波间隔分配的第二频率资源；根据第一频域位置在第一频率资源上接收信号，同时，根据第二频域位置在第二频率资源上接收信号，使得终端在支持两种系统信号配置，且每种系统信号配置中的子载波间隔不同时，可以同时在两种子载波间隔所对应的频率资源上接收信号，解决了终端只能在一种子载波间隔所对应的频率资源上接收信号，无法满足多种业务需求的问题，达到了扩展终端所能满足的业务需求的效果。
本公开中，终端接收的信号可以是同步信号，也可以是基本广播信号，下面分别对这两种信号的接收流程进行详细说明。
图3是根据另一示例性实施例示出的一种信号接收方法的流程图，该信号接收方法应用于图1所示的终端120中且信号是同步信号，如图3所示，该信号接收方法包括如下步骤。
在步骤301中，根据终端支持的频带，确定待接收的同步信号与第一子载波间隔对应的第一频域位置和同步信号与第二子载波间隔对应的第二频域位置。
同步信号、第一频域位置和第二频域位置的定义详见步骤201中的描述，此处不再赘述。
第一子载波间隔是为eMBB的业务需求配置的，为15kHz，第二子载波间隔是为URLLC的业务需求配置的，大于15kHz，比如，60kHz；或者，第一子载波间隔是为URLLC的业务需求配置的，大于15kHz，比如，60kHz，第二子载波间隔是为eMBB的业务需求配置的，为15kHz。
由于每个终端所支持的频带是固定的，且同步信号在频带中的频域位置是预先定义的，因此，终端可以根据频带确定出第一频域位置和第二频域位置。
在实现时，确定待接收的同步信号与第一子载波间隔对应的第一频域位置和信号与第二子载波间隔对应的第二频域位置，包括：将位于频带的中心频点处的预设频率资源块向上偏移与第一子载波间隔对应的第一阈值，得到第一频率资源块，按照同步信号与第一频率资源块的第一位置关系确定同步信号的第一频域位置；将预设频率资源块向下偏移与第二子载波间隔对应的第二阈值，得到第二频率资源块，按照同步信号与第二频率资源块的第二位置关系确定同步信号的第二频域位置。
相关技术中，终端确定同步信号的频域位置的方式如下：终端在支持的频带内确定出位于中心位置的6个RB(Resource Block，资源块)，将这6个RB作为位于中心频点处的预设频率资源块；再读取同步信号与预设频率资源块的位置关系，根据位置关系确定出同步信号在预设频率资源块中的频域位置。比如，对于FDD(Frequency Division Duplex，频分双工)制式的终端来说，位置关系为PSS周期出现在时隙0和时隙10的最后一个OFDM(Orthogonal Frequency Division Multiplexing，正交频分复用)符号的中间62个子载波上， SSS周期出现在时隙0和时隙10的倒数第二个OFDM符号的中间62个子载波上；对于TDD(Time Division Duplex，时分双工)制式的终端来说，位置关系为PSS周期出现在子帧1和子帧6的第三个OFDM符号的中间62个子载波上，SSS周期出现在子帧0和子帧5的最后一个OFDM符号的中间62个子载波上。
本实施例中，在确定第一频率资源块和第二频率资源块时，终端可以将预设资源块向上偏移与第一子载波间隔对应的第一阈值，得到第一频率资源块；将预设频率资源块向下偏移与第二子载波间隔对应的第二阈值，得到第二频率资源块。其中，第一阈值和第二阈值可以相等，也可以不等，且第一阈值和第二阈值的正负关系不作限定。比如，将位于中心位置的的6个RB向上偏移x，得到第一频率资源为“中心位置+x”的6个RB，将位于中心位置的的6个RB向下偏移x，得到第二频率资源为“中心位置-x”的6个RB。
第一位置关系可以与相关技术中的位置关系相同，也可以不同；第二位置关系可以与相关技术中的位置关系相同，也可以不同；且第一位置关系和第二位置关系可以相同，也可以不同，本实施例不作限定。
在步骤302中，确定在频带内为第一子载波间隔分配的第一频率资源和为第二子载波间隔分配的第二频率资源。
终端将频带内的一部分频率资源分配为第一频率资源，将频带内剩余的频率资源分配为第二频率资源。比如，当终端支持1901MHz-2000MHz的频带，且平均分配频率资源时，第一频率资源可以是1901MHz-1950MHz的频带，第二频率资源可以是1951MHz-2000MHz的频带。
在步骤303中，根据第一频域位置在第一频率资源上接收同步信号，同时，根据第二频域位置在第二频率资源上接收同步信号。
由于终端并不能确定出同步信号的时域位置，因此，终端可以根据第一频域位置在第一频率资源上盲搜同步信号，同时，根据第二频域位置在第二频率资源上盲搜同步信号。
在实现时，终端确定第一子载波间隔对应的第一频栅和第二子载波间隔对应的第二频栅；在第一频率资源上，将与第一频率资源块等大的第一扫描窗口以第一频栅为间隔扫描同步信号；同时，在第二频率资源上，将与第二频率资源块等大的第二扫描窗口以第二频栅为间隔扫描同步信号。
其中，频栅是频点之间间隔的最小单位。比如，15kHz子载波间隔对应的频栅是100kHz。子载波间隔和频栅之间具有对应关系，终端可以根据第一子 载波间隔和该对应关系确定第一频栅，根据第二子载波间隔和该对应关系确定第二频栅。
可选的，终端还可以根据两个子载波间隔和其中的一个频栅计算出另一个频栅。比如，第一子载波间隔为15kHz，第二子载波间隔为60kHz，且第一频栅为100kHz，则第二频栅＝100×(60/15)＝400kHz。
由于同步信号位于第一频率资源块和第二频率资源块中，因此，终端可以确定与第一频率资源块等大的第一扫描窗口，将第一扫描窗口以第一频栅为间隔扫描同步信号；同时，终端确定与第二频率资源块等大的第二扫描窗口，将第二扫描窗口以第二频栅为间隔扫描同步信号，本实施例不对扫描方式作限定。此时，频栅是扫描窗口的最小移动距离。
比如，第一频率资源块是6个RB、第一频栅为100kHz、第一频率资源为1901MHz-1950MHz的频带，则终端以100kHz的移动距离，利用6个RB的扫描窗口在1901MHz-1950MHz的频带上接收同步信号。
请参考图4所示的同步信号的接收示意图，其中，以第一子载波间隔为15kHz，第二子载波间隔为60kHz，同步信号在每种子载波上的周期为yms，且同步信号在不同子载波上的周期为y/2ms为例进行说明，由于终端同时在两种子载波间隔所对应的频率资源上接收同步信号，因此，图4中以两根重叠的箭头来表示DSP(Digital Signal Processing，数字信号处理)芯片在同一时隙位置上同时在两个子载波间隔所对应的频率资源上接收同步信号。
当终端在首次盲搜时即接收到完整的同步信号时，终端执行步骤304或305；当终端在首次盲搜时接收到同步信号的部分内容时，终端还可以根据同步信号的周期确定同步信号下次出现的时域位置，根据同步信号的频域位置和时域位置，在频率资源上接收同步信号，再执行步骤304或305。
由于终端可能在第一频率资源上接收到同步信号的部分内容，也可能在第二频率资源上接收到同步信号的部分内容，下面分别对这两种情况进行详细描述。
在第一种实现方式中，当在第一频率资源上接收到信号的部分内容时，根据信号当前的第一时域位置确定信号下次在第二频率资源上出现时的第二时域位置，在到达第二时域位置时，根据第一频域位置在第一频率资源上接收信号，同时，根据第二频域位置在第二频率资源上接收信号，第二时域位置早于信号下次在第一频率资源上出现时的第三时域位置。
由于同步信号之间的周期固定，因此，终端在接收到同步信号的部分内容时，可以计算出基站下一次发送同步信号的第二时域位置，从而根据第二时域位置接收同步信号，而不需要继续盲搜同步信号，可以节省资源。并且，基站在第一频率资源和第二频率资源上交替发送同步信号，这样，在不同的频率资源上发送的同步信号的周期为原来的二分之一，终端可以在一个频率资源上接收到同步信号的部分内容时，在等待二分之一的周期后在另一频率资源上接收到同步信号，而不用在等待一个周期后在同一频率资源上接收同步信号，可以提高同步信号的接收效率。
请参考图4，假设终端在当前时刻在15kHz子载波间隔对应的频率资源上接收到同步信号的部分内容，则可以确定出同步信号在60kHz子载波间隔对应的频率资源上的时域位置为y/2ms处，在等待了y/2ms后，终端在60kHz子载波间隔对应的频率资源上接收同步信号；而不需要在等待yms后，在15kHz子载波间隔对应的频率资源上接收同步信号。
在第二种实现方式中，当在第二频率资源上接收到信号的部分内容时，根据信号当前的第四时域位置确定信号下载在第一频率资源上出现时的第五时域位置，在到达第五时域位置时，根据第一频域位置在第一频率资源上接收信号，同时，根据第二频域位置在第二频率资源上接收信号，第五时域位置早于信号下次在第二频率资源上出现时的第六时域位置。
其中，第二种实现方式与第一种实现方式的区别在于在哪种频率资源上接收到同步信号的部分内容，两者的实现过程相似，此处不作赘述。
在终端接收到同步信号后，还需要根据同步信号继续接收基本广播信号，基本广播信号的接收方式与同步信号的发送方式相关，下面分别对基本广播信号的接收方式进行详细说明。
在步骤304中，当在第一频率资源和第二频率资源上均接收到同步信号时，根据在第一频率资源上接收到的同步信号确定基本广播信号在第一频率资源上出现时的第三频域位置和第七时域位置，并根据在第二频率资源上接收到的同步信号确定基本广播信号在第二频率资源上出现时的第四频域位置和第八时域位置；根据第三频域位置和第七时域位置在第一频率资源上接收基本广播信号，并根据第四频域位置和第八时域位置在第二频率资源上接收基本广播信号。
其中，终端在第一频率资源和第二频率资源上均接收到同步信号，是指， 终端在第一频率资源和第二频率资源上交替接收到同步信号，请参考图4。
终端在接收到同步信号后，可以根据同步信号先确定基本广播信号的频域位置，再确定基本广播信号的时域位置，根据频域位置和时域位置，在频率资源上接收基本广播信号。其中，在第一频率资源上接收到的同步信号可以指示在第一频率资源上发送的基本广播信号的时频位置，在第二频率资源上接收到的同步信号可以指示在第二频率资源上发送的基本广播信号的时频位置。
需要说明的是，由于基本广播信号在每种频率资源上的时频位置都是已知的，因此，终端可以在每种频率资源上对应的时频位置接收基本广播信号，而不需要同时在两种频率资源上对应的时频位置接收基本广播信号，可以节省资源。请参考图5所示的基本广播信号的接收示意图，以一根箭头来表示DSP芯片在一个频率资源上对应的时隙位置接收基本广播信号。
当然，终端也可以同时在两种频率资源上对应的时频位置接收基本广播信号，此时，应该以两根重叠的箭头来表示DSP芯片同时在两个频率资源上对应的时隙位置接收基本广播信号。
在步骤305中，当仅在第一频率资源上接收到同步信号时，根据同步信号确定基本广播信号在第一频率资源上出现时的第五频域位置和第九时域位置，并根据第九时域位置确定基本广播信号在第二频率资源上出现时的第十时域位置；根据第五频域位置和第九时域位置在第一频率资源上接收基本广播信号，并根据第十时域位置在第二频率资源上接收基本广播信号；或者，当仅在第二频率资源上接收到同步信号时，根据同步信号确定基本广播信号在第二频率资源上出现时的第六频域位置和第十一时域位置，并根据第十一时域位置确定基本广播信号在第一频率资源上出现时的第十二时域位置；根据第六频域位置和第十一时域位置在第二频率资源上接收基本广播信号，并根据第十二时域位置在第一频率资源上接收基本广播信号。
终端仅在第一频率资源上接收到同步信号，是指，同步信号仅在第一频率资源上发送。终端接收到同步信号后，可以根据同步信号确定在第一频率资源上发送的基本广播信号的第五频域位置，再确定基本广播信号的第九时域位置，根据第五频域位置和第九时域位置，在第一频率资源上接收基本广播信号。由于基本广播信号在第一频率资源和第二频率资源上交替发送的周期是已知的，因此，终端可以根据基本广播信号在第一频率资源上发送的第九时域位置和周期计算出基本广播信号在第二频率资源上发送的第十时域位置，根据第十 时域位置在第二频率资源上盲搜基本广播信号。
假设终端在当前时刻在15kHz对应的频率资源上接收到基本广播信号，则可以确定出基本广播信号在60kHz对应的频率资源上的时域位置为y/2ms处，在等待了y/2ms后，终端在60kHz对应的频率资源上盲搜基本广播信号。
终端仅在第二频率资源上接收到同步信号，是指，同步信号仅在第二频率资源上发送。终端接收到同步信号后，可以根据同步信号确定在第二频率资源上发送的基本广播信号的第六频域位置，再确定基本广播信号的第十一时域位置，根据第六频域位置和第十一时域位置，在第二频率资源上接收基本广播信号。由于基本广播信号在第一频率资源和第二频率资源上交替发送的周期是已知的，因此，终端可以根据基本广播信号在第二频率资源上发送的第十一时域位置和周期计算出基本广播信号在第一频率资源上发送的第十二时域位置，根据第十二时域位置在第一频率资源上盲搜基本广播信号。
综上所述，本公开提供的信号接收方法，通过根据终端支持的频带，确定待接收的信号与第一子载波间隔对应的第一频域位置和信号与第二子载波间隔对应的第二频域位置；确定在频带内为第一子载波间隔分配的第一频率资源和为第二子载波间隔分配的第二频率资源；根据第一频域位置在第一频率资源上接收信号，同时，根据第二频域位置在第二频率资源上接收信号，使得终端在支持两种系统信号配置，且每种系统信号配置中的子载波间隔不同时，可以同时在两种子载波间隔所对应的频率资源上接收信号，解决了终端只能在一种子载波间隔所对应的频率资源上接收信号，无法满足多种业务需求的问题，达到了扩展终端所能满足的业务需求的效果。
当在第一频率资源上接收到信号的部分内容时，根据信号当前的第一时域位置确定信号下次在第二频率资源上出现时的第二时域位置，由于第二时域位置早于信号下次在第一频率资源上出现时的第三时域位置，因此，终端可以缩短接收同步信号的周期，从而提高同步信号的接收效率。
图6是根据另一示例性实施例示出的一种信号接收方法的流程图，该信号接收方法应用于图1所示的终端120中且信号是基本广播信号，如图6所示，该信号接收方法包括如下步骤。
在步骤601中，根据终端支持的频带，确定待接收的基本广播信号与第一子载波间隔对应的第一频域位置和基本广播信号与第二子载波间隔对应的第 二频域位置。
在步骤602中，确定在频带内为第一子载波间隔分配的第一频率资源和为第二子载波间隔分配的第二频率资源。
在步骤603中，根据第一频域位置在第一频率资源上接收基本广播信号，同时，根据第二频域位置在第二频率资源上接收基本广播信号。
其中，终端同时在第一频率资源和第二频率资源上接收基本广播信号的流程，与，终端同时在第一频率资源和第二频率资源上接收同步信号的流程相同，详见图3所示的实施例中的描述，此处不作赘述。
需要说明的是，当信号是基本广播信号时，终端还需要在接收基本广播信号之前接收同步信号，接收同步信号的流程详见图3所示的实施例中的描述，此处不作赘述。

该第四接收模块870，被配置为根据第三确定模块确定的第三频域位置和第七时域位置在第一频率资源上接收基本广播信号，并根据第四频域位置和第八时域位置在第二频率资源上接收基本广播信号。
可选的，装置，还包括：第五接收模块880或第六接收模块890；
该第五接收模块880，被配置为当信号是同步信号，且仅在第一频率资源上接收到同步信号时，根据同步信号确定基本广播信号在第一频率资源上出现时的第五频域位置和第九时域位置，并根据第九时域位置确定基本广播信号在 第二频率资源上出现时的第十时域位置；根据第五频域位置和第九时域位置在第一频率资源上接收基本广播信号，并根据第十时域位置在第二频率资源上接收基本广播信号；或者，

综上所述，本公开提供的信号接收装置，通过根据终端支持的频带，确定待接收的信号与第一子载波间隔对应的第一频域位置和信号与第二子载波间隔对应的第二频域位置；确定在频带内为第一子载波间隔分配的第一频率资源和为第二子载波间隔分配的第二频率资源；根据第一频域位置在第一频率资源上接收信号，同时，根据第二频域位置在第二频率资源上接收信号，使得终端在支持两种系统信号配置，且每种系统信号配置中的子载波间隔不同时，可以同时在两种子载波间隔所对应的频率资源上接收信号，解决了终端只能在一种子载波间隔所对应的频率资源上接收信号，无法满足多种业务需求的问题，达到了扩展终端所能满足的业务需求的效果。
当在第一频率资源上接收到信号的部分内容时，根据信号当前的第一时域位置确定信号下次在第二频率资源上出现时的第二时域位置，由于第二时域位置早于信号下次在第一频率资源上出现时的第三时域位置，因此，终端可以缩短接收同步信号的周期，从而提高同步信号的接收效率。
