具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B。本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。并且，在本申请的描述中，除非另有说明，“多个”是指两个或多于两个。另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
本申请实施例提供了一种通信系统，该通信系统包括至少一个网络设备和至少一个终端，该至少一个终端中的一个或多个终端可以与该至少一个网络设备中的一个或多个网络设备通信。以一个网络设备和一个终端为例，参见图1，网络设备和终端可以进行无线通信。需要说明的是，在如图1所述的通信系统包含的网络设备和终端仅是一种示例，在本申请实施例中，所述通信系统包含的网元的类型、数量，以及网元之间的连接关系不限于此。
本申请实施例中的通信系统可以是支持第四代(fourth generation，4G)接入技术的通信系统，例如长期演进(long term evolution，LTE)接入技术；或者，该通信系统也可以是支持5G接入技术的通信系统，例如新无线(new radio，NR)接入技术；或者，该通信系统也可以是支持第三代(third generation，3G)接入技术的通信系统，例如通用移动通讯系统(universal mobile telecommunications system，UMTS)接入技术；或者，该通信系统还可以是支持多种无线技术的通信系统，例如支持LTE技术和NR技术的通信系统。另外，该通信系统也可以适用于面向未来的通信技术。
本申请实施例中的网络设备可以是接入网侧用于支持终端接入通信系统的设备，例如，可以是第二代(second generation，2G)接入技术通信系统中的基站收发信台(base transceiver station，BTS)和基站控制器(base station controller，BSC)、3G接入技术通信系统中的节点B(node B)和无线网络控制器(radio network controller，RNC)、4G接入技术通信系统中的演进型基站(evolved nodeB，eNB)、5G接入技术通信系统中的下一代基站(next generation nodeB，gNB)、发送接收点(transmission reception point，TRP)、中继节点(relay node)、接入点(access point，AP)等等，网络设备可以称为基站、节点或者接入网设备等。
本申请实施例中的终端可以是一种向用户提供语音或者数据连通性的设备，也可以称为用户设备(user equipment，UE)，移动台(mobile station)，用户单元(subscriber unit)， 站台(station)，终端设备(terminal equipment，TE)等。例如，终端可以为蜂窝电话(cellular phone)，个人数字助理(personal digital assistant，PDA)，无线调制解调器(modem)，手持设备(handheld)，膝上型电脑(laptop computer)，无绳电话(cordless phone)，无线本地环路(wireless local loop，WLL)台，平板电脑(pad)等。随着无线通信技术的发展，可以接入通信系统、可以与通信系统的网络侧进行通信，或者通过通信系统与其它物体进行通信的设备都可以是本申请实施例中的终端，譬如，智能交通中的终端和汽车、智能家居中的家用设备、智能电网中的电力抄表仪器、电压监测仪器、环境监测仪器、智能安全网络中的视频监控仪器、收款机等等。
针对不同网络制式的小区，可以通过频谱共享提高频谱利用率。在LTE小区和NR小区进行频谱共享时，参见图2中的(a)，若LTE小区和NR小区的覆盖区域一一对应，则一个LTE小区的频谱资源中的部分频谱资源可以共享给对应的NR小区，从而提高频谱利用率。在某些应用场景中，比如，为了扩大LTE小区的容量，参见图2中的(b)，可以将原本的一个LTE小区劈裂为两个，此时，相同覆盖区域内LTE小区的个数多于NR小区。此时，为了进行频谱共享，参见图2中的(c)，可以将原本的一个NR小区也劈裂为两个NR小区，使得LTE小区和NR小区的覆盖区域一一对应，此时，可以将一个LTE小区的频谱资源中的部分频谱资源共享给对应的NR小区。该方法虽然提高了频谱资源利用率，但是需要新增NR的基带板以支持更多的NR小区，增加了小区的部署成本。
在图2中，一个扇形区域代表1个小区，多个NR小区可以由一个或多个NR基站提供，多个LTE小区可以由一个或多个LTE基站提供。
本申请提供了一种确定频谱资源的方法，该方法可以实现相同覆盖区域内不同网络制式的小区的个数不同情况下的频谱共享，从而在避免增加小区部署成本的前提下，提高频谱利用率。
为便于理解本申请实施例，下面先对本文涉及的相关术语进行简单的介绍。
1、时分双工(time division deplux，TDD)
通信系统的一种双工通信技术，用于分离接收和发送的信道，即上下行链路。采用TDD模式的通信系统中，上下行链路使用相同的频域资源，通过不同时域资源来区分上行链路和下行链路。
2、频分双工(time division depluxing，FDD)
通信系统的一种双工通信技术，用于分离接收和发送的信道，即上下行链路。采用FDD模式的通信系统中，上下行链路使用相同的时域资源，通过不同频域资源来区分上行链路和下行链路，例如上行频率范围与下行频率范围不同。
3、载波聚合(carrier aggregation，CA)
CA是将2个或更多个分量载波(component carrier，CC)聚合在一起以支持更大的传输带宽的技术。CA可以分为上行CA和下行CA。针对上行CA，终端可以根据其能力在一个或多个CC上同时接收或发送。本申请实施例中将分量载波简称为载波。
4、辅助上行链路(supplementary uplink，SUL)
SUL是为终端配置的补充上行链路。目的是为了提高终端的上行覆盖。示例性的，参见图3，终端可以通过正常上行链路(normal uplink，NUL)发送上行信息，也可以通过SUL发送上行信息。NUL的覆盖区域小于SUL的覆盖区域。SUL所覆盖的范围可以称为 SUL小区。
本申请实施例的执行主体可以是网络设备。网络设备可以为管理第一小区的基站，也可以为管理第二小区的基站，还可以是除管理第一小区的基站和管理第二小区的基站之外的独立设备。共享信息可以是配置在网络设备中的，例如，可以由运营商配置。共享信息也可以是输入至网络设备中的，例如，可以由网管输入。
本申请实施例提供了一种确定频谱资源的方法，如图4所示，包括：
401、获取共享信息，共享信息指示N个第一小区和一个第二小区共享第一频段。
其中，N个第一小区中的每个第一小区均与第二小区的覆盖区域有重叠，N为大于1的整数。
其中，N个第一小区可以为N个相邻的第一小区。N个第一小区可以由一个基站管理，也可以由多个基站管理。
可选的，第一小区和第二小区的网络制式不同。例如，第一小区为LTE小区，第二小区为NR小区，该情况下，网络设备可以是LTE基站或NR基站或除LTE基站和NR基站之外的独立设备。进一步的，第二小区可以为NR小区中的普通小区或SUL小区。
与一个第二小区的覆盖区域有重叠的多个第一小区以及该第二小区可以组成一个频谱共享组，一个频谱共享组中的不同网络制式的小区可以进行频谱共享。进一步的，相同覆盖区域内的第二小区和多个第一小区可以组成一个频谱共享组。例如，参见图2中的(b)，相同覆盖区域内的1个NR小区和2个LTE小区可以组成一个频谱共享组。
在具体实现时，第二小区中可以定义N个波束(Beam)，一个Beam的覆盖区域与一个第一小区的覆盖区域部分或完全重叠，该Beam与该第一小区进行频谱共享。
第一频段可以为任意一个频段，示例性的，第一频段可以为1.8G的全部频段或其中的一部分、3.5G的全部频段或其中的一部分等，本申请实施例对第一频段不作具体限定。
402、确定N个第一小区各自的频谱资源，以及第二小区的频谱资源。
N个第一小区各自的频谱资源，以及第二小区的频谱资源都位于第一频段中。
在第一种可选的实施方式中，可以将第二小区的频谱资源称为第一频谱资源，第一频谱资源与N个第一小区中的每个第一小区在第一频段中的频谱资源不重叠。
在第二种可选的实施方式中，第二小区的频谱资源可以包括N个第二频谱资源，分别为第n个频谱资源，n的取值为取遍1，2，…，至N的整数。
在第二种可选的实施方式中，步骤402具体可以通过如下方式实现：确定N个第一小区中的第n个第一小区在第一频段中的频谱资源，确定第二小区的第n个第二频谱资源，在第二小区和第n个第一小区的覆盖重叠区域中，第n个第二频谱资源与第n个第一小区在第一频段中的频谱资源不重叠。
其中，不同第一小区在第一频段中的频谱资源可以部分或全部重叠，也可以完全不重叠。N个第二频谱资源中的任意两个第二频谱资源可以部分或全部重叠，也可以完全不重叠。第一频段中第一小区的频谱资源和第二小区的频谱资源可以占满整个第一频段，也可以占据第一频段的一部分，本申请实施例中以第一小区的频谱资源和第二小区的频谱资源占满整个第一频段为例对本申请实施例提供的方法作示例性说明。
示例性的，若N＝2，第一小区为LTE小区，第二小区为NR小区。
在上述第一种实施方式中，N个LTE小区各自的频谱资源和NR小区的第一频谱资源的 位置可参见图5。
在上述第二种实施方式中，N个LTE小区各自的频谱资源和NR小区的N个第二频谱资源的位置可参见图6。
若第一小区为LTE小区，第二小区为NR小区，本申请实施例提供的方法可以实现多个LTE小区和一个NR小区的频谱共享，从而提升频谱资源的利用率和NR小区容量，并且不需要新建多个NR小区，可以避免增加小区部署成本。
在步骤402之前，可选的，上述方法还包括：获取频谱资源需求信息。该情况下，步骤402在具体实现时可以包括：根据频谱资源需求信息确定N个第一小区中的每个第一小区在第一频段中的频谱资源，并确定第二小区的第一频谱资源或第n个第二频谱资源。
频谱资源需求信息包括以下信息中的一种或多种：
信息1、N个第一小区中的每个第一小区的频谱资源需求信息。
信息2、第二小区的频谱资源需求信息。
信息3、第二小区与第n个第一小区的覆盖重叠区域内第二小区的频谱资源需求信息。
其中，一个小区的频谱资源需求信息可以为该小区需求的资源块(resource block，RB)的个数信息，需求的子载波的个数信息等。
步骤402在具体实现时，根据频谱资源需求信息中包括的信息的不同，可以有不同的实现方式，以下通过情况1至情况3分别进行描述。
情况1、频谱资源需求信息至少包括N个第一小区中的每个第一小区的频谱资源需求信息。
在情况1下，步骤402在具体实现时，可以根据N个第一小区中的每个小区的频谱资源需求信息在第一频段中为N个第一小区分配频谱资源，再在第一频段中剩余的频谱资源中为第二小区分配第一频谱资源或第n个第二频谱资源。
示例性的，若N个第一小区为LTE小区0和LTE小区1，第二小区为NR小区，LTE小区0需求的RB个数为10，LTE小区1需求的RB个数为15，第一频段共30个RB。参见图7中的(a)，可以在第一频段中为LTE小区0分配10个RB，为LTE小区1分配15个RB，为LTE小区1分配的15个RB包含为LTE小区0分配的10个RB的。该情况下，可以将第一频段中的除为LTE小区1分配的15个RB之外的15个RB为第二小区分配，该15个RB即第一频谱资源。参见图7中的(b)，可以在第一频段中为LTE小区0分配10个RB，为LTE小区1分配15个RB，为LTE小区1分配的15个RB包含为LTE小区0分配的10个RB的。该情况下，在NR小区与LTE小区0的覆盖重叠区域内，将第一频段中的除为LTE小区0分配的10个RB之外的20个RB为第二小区分配，该20个RB即第1个第二频谱资源。在NR小区与LTE小区1的覆盖重叠区域内，将第一频段中的除为LTE小区1分配的15个RB之外的15个RB为第二小区分配，该15个RB即第2个第二频谱资源。
情况2、频谱资源需求信息至少包括第二小区的频谱资源需求信息。
在情况2下，步骤402在具体实现时，可以根据第二小区的频谱资源需求信息在第一频段中为第二小区分配第一频谱资源，再在第一频段中剩余的频谱资源中为终端分配N个第一小区中的每个小区的频谱资源。
示例性的，若N个第一小区为LTE小区0和LTE小区1，第二小区为NR小区，NR小区 需求的RB个数为15，第一频段共30个RB。参见图7中的(a)，可以在第一频段中为第二小区分配15个RB，该15个RB即第一频谱资源。该情况下，若LTE小区0需求的RB个数为10，LTE小区1需求的RB个数为15。再在第一频段中的除为第二小区分配的15个RB之外的15个RB中为LTE小区0分配10个RB，为LTE小区1分配15个RB，为LTE小区1分配的15个RB包含为LTE小区0分配的10个RB的。
情况3、频谱资源需求信息至少包括第二小区与第n个第一小区的覆盖重叠区域内第二小区的频谱资源需求信息。
在情况3下，步骤402在具体实现时，可以根据第二小区与第n个第一小区的覆盖重叠区域内第二小区的频谱资源需求信息在第一频段中为第二小区分配第n个第二频谱资源，再在第一频段中剩余的频谱资源中为终端分配N个第一小区中的每个小区的频谱资源。
示例性的，若N个第一小区为LTE小区0和LTE小区1，第二小区为NR小区，NR小区与LTE小区0的覆盖重叠区域内NR小区的频谱资源需求的RB个数为20，NR小区与LTE小区1的覆盖重叠区域内NR小区的频谱资源需求的RB个数为15，第一频段共30个RB。参见图7中的(b)，在NR小区与LTE小区0的覆盖重叠区域内，为NR小区分配20个RB，该20个RB即第1个第二频谱资源。在NR小区与LTE小区1的覆盖重叠区域内，为NR小区分配15个RB，该15个RB即第2个第二频谱资源。该情况下，若LTE小区0需求的RB个数为10，LTE小区1需求的RB个数为15。再将第一频段中的除第1个第二频谱资源之外的10个RB分配给LTE小区0，将第一频段中的除第2个第二频谱资源之外的15个RB分配给LTE小区1。
在步骤402之后，若网络设备为LTE基站，该方法还包括：LTE基站向NR基站发送第二小区的第一频谱资源的信息或第二小区的N个第二频谱资源的信息。若网络设备为NR基站，该方法还包括：NR基站向LTE基站发送N个第一小区中的每个第一小区的频谱资源的信息。LTE基站和NR基站之间可以通过X2接口交互信息。
若网络设备为独立设备，该方法还包括：向NR基站发送第二小区的第一频谱资源的信息或第二小区的N个第二频谱资源的信息，向LTE基站发送N个第一小区中的每个第一小区的频谱资源的信息。
后续过程中，LTE基站根据N个第一小区中的每个第一小区的频谱资源对N个第一小区的数据进行调度，NR基站根据第二小区的第一频谱资源或第二小区的N个第二频谱资源对第二小区的数据进行调度。
基于上述确定的频谱资源，网络设备在对终端的数据调度时可以有以下两种情况。
情况一、
当一个终端位于第n个第一小区的覆盖区域、且终端对N个第一小区中的其他第一小区的干扰均小于或等于第一阈值时，在第n个第二频谱资源上对终端的数据进行调度，其中，终端的服务小区为第二小区。
情况二、
当一个终端位于第n个第一小区的覆盖区域、且终端对N个第一小区中的其他任意一个第一小区的干扰大于第一阈值时，在第一频谱资源上对终端的数据进行调度，终端的服务小区为第二小区。
其中，上述情况一和情况二中的对一个小区的干扰可以包括对该小区中的终端的下行接收的干扰和/或对管理该小区的基站的上行接收的干扰。第一阈值可以为预设的或预 定义的，也可以为网络设备配置的，还可以为根据实际的应用场景确定的。示例性的，第一阈值可以为在相邻小区测量终端的探测参考信号(sounding reference signal，SRS)的参考信号接收功率(reference signal receiving power，RSRP)的门限或终端上报的相邻小区的下行RSRP的门限。
针对服务小区为第二小区的终端，当终端位于一个第一小区的覆盖区域内且对其他第一小区的干扰均小于或等于第一阈值时，这些终端可以记为第一类型终端。当终端位于一个第一小区的覆盖区域内、且对其他任意一个第一小区的干扰大于第一阈值时，这些终端可以记为第二类型终端。
可选的，该方法还包括：NR基站确定服务小区为第二小区的每个终端是第一类型终端还是第二类型终端。若服务小区为第二小区的所有终端均为第二类型终端，则NR基站在为第二类型终端分配资源时，分配第一频谱资源中的资源，并且第一频谱资源中的相同的资源仅分配给一个第二类型终端，从而避免第二类型终端之间的干扰。若一个服务小区为第二小区的终端为第一类型终端，如果该终端位于第二小区与第n个第一小区的覆盖重叠区域内，则NR基站可以将第n个第二频谱资源中的资源分配给该终端，由于该终端不会对其他终端产生干扰，因此，位于其他第一小区的覆盖范围中的终端若使用第n个第二频谱资源中的资源时也可以正常使用，互不影响。
该可选的方法在具体实现时，NR基站可通过上行信号接收质量和/或下行信号接收质量确定第二小区内的每个终端是第一类型终端还是第二类型终端。其中，上行信号接收质量可以为NR基站的上行接收天线的各个接收端口对终端发送的信号(例如，SRS)测量的RSRP，下行信号接收质量可以为终端对NR基站发送的信号测量的RSRP。
示例性的，若N个第一小区为LTE小区0和LTE小区1，NR基站可以通过4个天线端口对终端发送的SRS进行测量，4个天线端口中第1个和第2个天线端口所采用的接收波束朝向LTE小区0，第3个天线端口和第4个天线端口所使用的接收波束朝向LTE小区1，则若第1个和第2个天线端口对SRS测量得到的RSRP与第3个和第4个天线端口对SRS测量得到的RSRP相近，则说明该终端为第二类型终端，若第1个和第2个天线端口对SRS测量得到的RSRP与第3个和第4个天线端口对SRS测量得到的RSRP相差较远，则说明该终端为第一类型终端。
上述实施例中，第一频段可以为用于上行传输的频段，也可以为用于下行传输的频段，也可以既包含用于上行传输的频段，还包含用于下行传输的频段。
可选的，若第一频段为用于上行传输的频段，一种情况下，第二小区中包含第一频谱资源或第二频谱资源的载波作为第二小区的SUL。另一种情况下，第二小区中包含第一频谱资源或第二频谱资源的载波用于与其他载波进行上行CA。若第一频段为用于下行传输的频段，第二小区中包含第一频谱资源或第二频谱资源的载波用于与其他载波进行下行CA。
第一频段可以为FDD频段，也可以为TDD频段。在具体实现时，LTE小区和NR小区可以共享上行频谱资源和/或下行频谱资源，从而为5G网络提供NR的FDD频谱资源或使得5G网络支持下行CA或使得5G网络支持上行CA等。以第一频段为FDD频段为例，本申请实施例提供的方法可以应用于多种场景中。例如，在运营商无独立的NR的FDD频谱资源的情况下，参见图8，LTE小区和NR小区可以共享上行频谱资源，为5G网络提供NR的 FDD上行频谱资源，从而支持SUL，提升NR小区的上行覆盖。再例如，在运营商无独立的NR的FDD频谱资源的情况下，参见图9，LTE小区和NR小区可以共享上行频谱资源和下行频谱资源，为5G网络提供NR的FDD上行频谱资源和NR的FDD下行频谱资源，从而支持FDD的NR。再例如，参见图10，LTE小区和NR小区可以共享下行频谱资源，为5G网络提供NR的FDD下行频谱资源，从而支持NR小区的下行CA等。
本申请实施例中的频段也可以称为频带。
上述主要从方法角度对本申请实施例的方案进行了介绍。可以理解的是，确定频谱资源的装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和软件模块中的至少一个。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
本申请实施例可以根据上述方法示例对确定频谱资源的装置进行功能单元的划分，例如，可以对应各个功能划分各个功能单元，也可以将两个或两个以上的功能集成在一个处理单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。需要说明的是，本申请实施例中对单元的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
