应理解，本发明实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile Communication，简称为“GSM”)系统、码分多址(Code Division Multiple Access，简称为“CDMA”)系统、宽带码分 多址(Wideband Code Division Multiple Access，简称为“WCDMA”)通用分组无线业务(General Packet Radio Service，简称为“GPRS”)系统、长期演进(Long Term Evolution，简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex，简称为“FDD”)系统、LTE时分双工(Time Division Duplex，简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System，简称为“UMTS”)、全球互联微波接入(Worldwide Interoperability for Microwave Access，简称为“WiMAX”)通信系统，以及未来的5G通信系统等。
本发明实施例应用的通信系统中包括用户设备和网络设备。
用户设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，用户设备可以指(User Equipment，简称为“UE”)、接入用户设备、用户单元、用户站、移动站、移动台、远方站、远程用户设备、移动设备、无线通信设备、用户代理或用户装置。接入用户设备可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，简称为“SIP”)电话、无线本地环路(Wireless Local Loop，简称为“WLL”)站、个人数字处理(Personal Digital Assistant，简称为“PDA”)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的用户设备等。
网络设备可以是用于与用户设备进行通信的设备，例如，可以是GSM系统或CDMA中的网络设备(Base Transceiver Station，简称为“BTS”)，也可以是WCDMA系统中的网络设备(NodeB，简称为“NB”)，还可以是LTE系统中的演进型网络设备(Evolutional Node B，简称为“eNB”或“eNodeB”)，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络侧设备或未来演进的PLMN网络中的网络设备等。
滤波的正交频分复用(Filtered Orthogonal Frequency Division Multiplex，简称为“F-OFDM”)是一种改进的正交频分复用技术，其基本原理是，通过把一个载波，划分成不同的子带，对每个子带进行滤波，并在子带边缘预留一定的保护带，从而使得子带和子带之间是不相关的，子带与子带之间互不影响。各子带的带宽可以不相同，子带的带宽根据业务需求来确定。
图1为F-OFDM处理过程的简略框图。如图1所示，一个载波被划分为N个子带，每个子带占用一定的带宽，每个子带的数据独立处理，每个子带的配置信息可以不同，最后对每个子带单独滤波后，叠加在一起，在空口发射。不同子带的物理层基本参数(numerology)可以相同，也可以不同。子带的物理层基本参数包括子载波带宽、传输时间间隔(Transmission Time Interval，简称为“TTI”)长度、符号长度、符号数，以及循环前缀(Cyclic Prefix，简称为“CP”)长度等参数中的至少一个。子带的物理层基本参数可以是预先配置好的，也可以根据业务负载等情况灵活的适配。通常不同物理层基本参数配置的子带适合于不同的业务类型。本发明实施例中子带的物理层基本参数不同可以是子载波带宽、传输时间间隔(Transmission Time Interval，简称为“TTI”)长度、符号长度、符号数，以及循环前缀(Cyclic Prefix，简称为“CP”)长度等参数中有一个不同或者有多个不同，例如：不同子带的TTI不同。
本发明实施例中，子带的配置信息用于所述用户设备或者网络设备定位所述子带并使用所述子带，所述子带的配置信息可以包括系统当前配置的子带的位置和带宽，可以包括子带的物理层基本参数，也可以不包括子带的物理层基本参数。在配置信息中可以包括子带的标识信息，需要通过子带的标识信息在预先配置的物理层基本参数中确定该子带的物理层基本参数，如果在配置信息中包括子带的物理层基本参数。另外，可选地，子带的配置信息中还可以包括子带的频率范围、子带的频率中心点、子带的负载情况或空闲情况、子带的覆盖情况或功率等级，业务类型标识、子带的优先级，上下行子带的对应关系等。
F-OFDM由于能够对子带进行滤波，使得子带之间相互不影响，从而能够对子带配置不同的物理层基本参数，以适应不同业务和环境的特性，把不同特性的业务放到最适合的子带中传输，提高整个系统的性能。而不会出现子带之间出现明显的干扰，影响系统或子带的性能。
为了达到以上目的，本发明实施例中设计了子带划分、配置和重配置的方法，以及子带信息如何通知到用户设备的相关方案。
参阅图2，本发明实施例提供的通信的方法的一实施例包括：
S101、网络设备获取第一子带的配置信息和第二子带的配置信息，所述第 二子带的配置信息包括所述第二子带的标识信息，所述第二子带的标识信息用于所述用户设备确定所述第二子带的物理层基本参数，所述第一子带的物理层基本参数和所述第二子带的物理层基本参数不同。
本发明实施例中，第二子带可以有一个，也可以有多个。
获取第一子带的配置信息和第二子带的配置信息的方式可以有多种，例如：读取预置文件中第一子带的配置信息和第二子带的配置信息。
可选地，所述配置信息还包括所述第二子带的位置、带宽、物理层基本参数、频率范围、频率中心点、负载情况、所支持业务的类型标识和优先级中的至少一个。
可选地，所述物理层基本参数包括子载波带宽、传输时间间隔TTI、符号长度、符号数和循环前缀CP长度中的至少一个。
S102、网络设备确定第一子带和第二子带。
可选地，所述网络设备确定第一子带和第二子带，可以包括：
所述网络设备根据业务环境的类型确定第一子带，根据业务的类型确定第二子带。
本发明实施例中，业务环境的类型指的是网络设备所处的业务环境，例如：当网络设备同时兼容长期演进(Long Term Evolution，简称为“LTE”)系统时，则该业务环境的类型就是LTE的类型，当要兼容其他2G或3G通信系统时，则该业务环境的类型就是其他2G或3G通信系统的类型。
可选地，所述下行载波带宽中的下行子带是依据下行业务需求进行划分的，上行载波带宽中的上行子带是依据上行业务需求进行划分的，所述下行业务需求与上行业务需求不同时，所述下行子带的划分和所述上行子带的划分也不同。
S103、网络设备在所述第一子带上发送所述第二子带的配置信息。
S104、用户设备接收所述网络设备发送的第二子带的配置信息后，通过所述第二子带与网络设备通信。
与现有技术中一个载波只有一种波形和物理层基本参数，无法适应多业务需求相比，本发明实施例提供的通信的方法，网络设备可以将不同物理层基本 参数的子带的配置信息发送给用户设备，网络设备和用户设备可以通过不同的子带进行通信，从而满足通信业务多样化的需求。
可选地，所述方法还包括：
所述网络设备在所述第一子带上发送第三子带的配置信息；
所述用户设备从所述第一子带上接收第三子带的配置信息；
其中，当所述第二子带为上行子带时，所述第三子带为下行子带，当所述第二子带为下行子带时，所述第三子带为上行子带。
可选地，所述方法还包括：当所述用户设备从第一子带上接入时，所述网络设备还根据所述用户设备的业务类型，将所述用户设备切换到与所述业务类型对应的第二子带上。
本发明实施例中，通信系统通常包括频分双工(Frequency Division Duplex，简称为“FDD”)系统和时分双工(Time Division Duplex，简称为“TDD”)系统，FDD系统上下行频率资源的频谱范围是不同的，可以同时进行上下行的数据传输。TDD系统上下行频率资源的频谱范围是相同的，只是时间上不同，上下行交替使用该范围内的频谱资源。
FDD系统为上下行频分系统，为简化F-OFDM波形技术应用到实际系统的设计，从整个系统考虑，不导致其他必要功能的设计过于复杂，比如混合自动重传请求(Hybrid Automatic Repeat request，简称为“HARQ”)、同步、广播、和调度等，同时也要考虑并满足未来业务的多样性要求，对F-OFDM的子带划分做了如图3和图4所示的设计。
图3是FDD系统下行子带划分示意图，图4是FDD系统上行子带划分示意图。
子带的数量可以有多个，并不是一定是图3和图4中所示的几个，可以是n个(n>＝1)，子带的带宽，可以根据需要进行配置。
在下行子带中可以定义一个主子带和多个从子带，下行主子带主要用于传输系统消息、传输从子带的配置信息。下行从子带主要用于下行业务数据的传输。例如：图3中，第一子带可以理解为是下行主子带，第二子带1至第二子带5可以理解为下行从子带。
实际上，上行子带中也可以有上行主子带和上行从子带，上行主子带主要用户传输从下行主子带上接收的消息的响应消息，上行从主带主要用于上行业务数据的传输。例如：图4中，第三子带可以理解为是上行主子带，第四子带1至第四子带3可以理解为是上行从子带。
需要说明的是，图3和图4中的第二子带、第三子带和第四子带只是在该场景中为了便于说明而标的序号，并不限定权相中所描述的第二子带和第三子带一定是图3和图4中的第二子带和第三子带。
作为一种可能的实施方式，可以将权相中的第二子带理解为是图3中的第二子带1至第二子带5，可以将权相中的第三子带理解为是图4中的第三子带和第四子带1至第四子带3。
下行载波或上行载波在子带划分时，可以划分为多个相同或者不同带宽的子带。任何一个子带在时域上占用至少一个无线帧，也就是子带在一个无线帧内不变。
通常情况下，用户设备首先通过第一子带接收系统信息，并获知第二子带和上行子带的配置信息。
第一子带的位置通常设置在载波频带的中心点，初始带宽和相关参数可以根据网络设备所处的默认业务环境进行设定；当然第一子带的位置也可以不位于频带的中心点，本发明实施例中对此不做具体限定。
第一子带必须设置，其所占用的带宽可以调整。为了与长期演进(Long Term Evolution，简称为“LTE”)系统兼容，第一子带的物理层基本参数可以设置为LTE系统的典型参数，比如TTI大小为1ms，waveform为典型的OFDM，子载波间隔为15kHz。
网络设备在第一子带上下发第二子带和上行子带的配置信息给覆盖范围内的用户设备。
一般用户设备在初始接入时，首先从第一子带接入；接入之后，根据用户设备的业务特性，网络设备可以把用户设备切换到对应的第二子带上工作。因为用户设备可以同时进行不同的业务，所以用户设备可以同时工作在多个第二子带。
本发明实施例中，网络设备还会为下行子带和上行子带配置对应关系，并通过第一子带向用户设备发送该对应关系，该对应关系用于指示用户设备从对应关系中的上行子带上反馈响应数据，该响应数据是针对从所述对应关系的下行子带上接收的数据做出的。例如：该对应关系中包括：第二子带1和第三子带3，则用户设备从第二子带1上接收的数据需要在第三子带3上向网络设备反馈响应数据。
可选地，所述方法还包括：
所述网络设备在所述第一子带上发送与所述第一子带对应的上行子带的信息；
所述用户设备从所述第一子带上接收与所述第一子带对应的上行子带的信息；
所述与所述第一子带对应的上行子带和所述第一子带的TTI相匹配。
与所述第一子带对应的上行子带的信息的表达形式可以是通过对应关系的形式来表示的，与所述第一子带对应的上行子带的信息可以是预先配置好的，也可以是网络设备动态配置的。
可选地，所述方法还包括：
当所述第二子带为下行子带时，所述网络设备在所述第一子带上发送与所述第二子带对应的上行子带的信息；
当所述第二子带为下行子带时，所述用户设备从所述第一子带上接收与所述第二子带对应的上行子带的信息；
所述与所述第二子带对应的上行子带和所述第二子带的TTI相匹配。
当所述第二子带为上行子带时，所述网络设备在所述第一子带上发送与所述第二子带对应的下行子带的信息；
当所述第二子带为上行子带时，所述用户设备从所述第一子带上接收与所述第二子带对应的下行子带的信息；
所述与所述第二子带对应的下行子带和所述第二子带的TTI相匹配。
当所述第二子带为下行子带时，与所述第二子带对应的下行子带的信息，或者，当所述第二子带为上行子带时，与所述第二子带对应的下行子带的信可 以是预先配置好的，也可以是网络设备动态配置的。
当所述第二子带为下行子带时，所述用户设备根据所述与第二子带对应的上行子带信息，从所述第二子带上接收下行数据后，从与所述第二子带对应的所述至少一个上行子带上向所述网络设备反馈应答数据。
当所述第二子带为上行子带时，所述用户设备从与该第二子带对应的下行子带上接收数据后，从该第二子带反馈应答数据。
上述实施例中上下行子带之间的对应，都可以用对应关系来表达。
在FDD系统中一般情况是下行业务占据一个频段带宽，上行业务占据另一个频段带宽。上下行子带通常都需要有一个对应关系。只有在特殊的情况下的下行子带才不需要与之关联的上行子带。例如：某些做广播业务的子带，可以没有关联的上行子带。
图5是FDD系统上下行子带关联示意图。
如图5所示，下行子带包括第一子带和第二子带1至第二子带5，上行子带包括第三子带和第四子带1至第四子带3。第一子带与第三子带存在前述所描述的对应关系。这种对应关系后面都描述为对应。第二子带1与第四子带2对应，第二子带2与第四子带1对应，第二子带3与第四子带2对应，第二子带4与第四子带3对应，第二子带5没有对应的上行子带。
从图5中可以看出，无论是带宽还是在载波中的相对位置，上下行子带之间的对应关系是不对称的，上下行子带之间的对应关系是根据上下行的业务需求进行配置的；上下行子带的对应关系也不是一对一的，当然，也可以是一对一，还可以是一对多，或多对一，或多对多的关系。也就是两个或多个下行子带对应的上行子带可以是同一个；或者某个下行子带，可以对应多个上行子带。这种上下行子带的对应关系，可以在系统初始化时设定，也可以在系统运行过程中根据需要动态的调整，以适应业务场景的动态变化。
例如：下行的第二子带3和第二子带1都与上行的第四子带2对应；第二子带子带5没有对应的上行子带，说明下行的第二子带5没有对应的上行业务，该第二子带5可能是用于广播业务的子带。
另外，需要说明的是，上下行子带在划分上是独立的。下行子带和上行子 带在配置信息的配置上也是各自独立的。由于上下行在业务特性上本身是有区别的，所以，上下行子带为了更好的传输各自的业务，本身也要求独立的配置信息，比如典型的上下行业务量是不对称的，那么下行子带对应的上行子带的带宽是可以配置不同的；又比如，上下行使用不同的waveform，也是一种典型的设置。
另外，从整个载波来说，上下行的载波带宽也可以不同，根据上下行业务和可用带宽来调整。
为了简化系统设计，一般要求上述对应关系中的上下行子带的TTI相匹配，也就是说，采用相同的TTI长度，或者要求下行子带的TTI是上行子带的TTI整数倍，以保证HARQ的反馈能够及时。
对于一些特殊的应用场景或业务，用户设备也可以直接从对应的从子带接入。可以有一些特殊的子带。
特殊子带：针对某种特殊场景或单一功能的用户设备的特殊接入子带，以满足场景限制或功能限制
特殊子带，比如用于物联网的机器对机器通信(Machine Type Communication，简称为“MTC”)的子带，MTC业务是5G网络需要支持的基本业务。MTC的用户设备由于成本或耗电的特殊要求，在系统设计上需要支持MTC业务的用户设备，能够直接接入到支持MTC业务的子带。MTC子带提供预设参数的快速接入，减少MTC用户设备网络搜索的时间，以及能力要求。
特殊子带，比如用于高速移动的用户设备接入的子带，高速接入子带对于处于高速运动的用户设备，由于第一子带的设计是用于普通中低速移动的用户设备接入的；高速移动的用户设备在第一子带上将难以接入，必须设置专门的用于高速移动用户设备的接入。
特殊子带，比如用于广播的子带，广播子带一般是下行子带，广播子带一般用于面向整个覆盖范围内进行广播业务，广播子带一般不用关联专门的上行子带。
但在使用蜂窝网络进行大范围的广播业务时，也可能存在需要用户设备反馈或接入广播业务的诉求。这种情况下，因为上行数据只是一些信令传输或简 单反馈，这中情况下可以将广播子带随机关联到任意一个上行子带上。
特殊子带，比如空子带：为了减少系统干扰和能耗，如果业务量较低，并不需要相应的带宽资源来进行业务，那么多余的带宽资源就可以空出来，形成空子带。空子带，顾名思义，就是不发送任何信息的子带，在第一子带的子带广播消息中也不发送空子带的配置信息。
空子带的位置，可以在除第一子带外，网络设备频带范围内的任何位置出现。有时系统如果突然出现一些窄带干扰，也可以把干扰位置重配为空子带，以避开干扰的影响。
在同频组网的情况下，空子带也可以用来协调小区边缘的频谱分配，降低小区边缘的同频干扰问题。
本发明实施例中，可以为各第二子带设置优先级，还可以为各上行子带设置优先级，子带优先级的设置是为了区分不同优先级的用户或业务，使得高优先级的用户或业务能够获得相应的服务资源，保障其满意度。
这样针对某些高优先级的子带只有优先级较高的用户才能接入，有利于保障重要用户的业务质量。
不是所有用户设备或子带都需要设置优先级，子带或用户设备如果不设置优先级，就默认为某个优先级。
子带跳频：由于5G单个载波可以达到数百兆的带宽，每个载波的带宽内可以划分出多个不同带宽的子带。为了能够利用这么大带宽的频率分集增益，可以对子带进行跳频。
子带跳频有多种方式：固定模式跳频：可以设置几种固定跳频模式；根据频率分集增益的预估结果，进行动态跳频。跳频的方式在系统消息中进行广播或通过单播通知连接态的用户设备。
TDD系统上下行是通过时间区分的，也就是说，系统上下行业务占用同样的载波带宽，在一段时间用于下行业务，一段时间用于上行业务，这样交替进行。图6是一个典型的TDD系统子带划分示意图：
图6中可以看出，在上下行发射的各自时间内，载波带宽被划分成多个子带，每个子带占用一定的带宽；上行时间内的子带划分和下行时间内的子带划 分是独立的。
在TDD系统中，上下行子带之间也是存在对应关系的，下行子带包括第一子带和第二子带1至第二子带5，上行子带包括第三子带和第四子带1至第四子带3。第一子带与第三子带存在前述所描述的对应关系。这种对应关系后面都描述为对应。第二子带1与第四子带2对应，第二子带2与第四子带1对应，第二子带3与第四子带2对应，第二子带4与第四子带2和第四子带3对应，第二子带5与第四子带3对应。
对应关系的描述可以参阅FDD系统中的相关描述进行理解，本处不做过多赘述。
由于业务或通信环境的变化，系统现有的子带，可能不能最好的适配新的业务或环境，需要重新调整子带，并对调整后的子带重新下发配置信息，来最佳的适配系统的业务需求或通信环境情况。这就涉及到子带的重配。
可选地，所述网络设备确定需要进行子带重配，则获取重配后的各子带的配置信息；
所述网络设备通过所述第一子带发送重配后的各子带的配置信息；或者，
所述网络设备通过所述第一子带向处于空闲态的用户设备发送所述重配后的各子带的配置信息，通过所述第二子带向在所述第二子带上有业务传输的用户设备发送所述重配后的各子带的配置信息。
所述用户设备在子带重配后，从所述第一子带上接收重配后的各子带的配置信息。
在子带重配后，当所述用户设备正在使用所述第二子带传输业务时，从所连接的第二子带上接收重配后的各子带的配置信息，所述所连接的第二子带为下行子带；
在子带重配后，当所述用户设备处于空闲态时，从所述第一子带上接收重配后的各子带的配置信息。
本发明实施例中，因为子带在重配后，子带的配置信息都相应的发生了变化，用户设备再去获取原来的配置信息已经没有使用价值了，所以网络设备在准备重配时，会通过第一子带下发重配标志位，该重配标志位可以是在系统消 息中下发的。
可选地，当子带重配是周期性重配时，在所述重配周期开始前的预置时刻，所述网络设备将重配标志位的状态值修改到准备子带重配的状态，在所述重配周期开始时，所述网络设备将所述重配志位的状态值修改到已完成重配状态。
所述用户设备当识别所述子带重配标志位的状态值处于准备子带重配的状态时，停止接入所述第二子带。
图7是子带重配示意图。如图7所示，一般情况下，系统会设置一个子带的重配周期，在重配周期到来的时候，系统才会重配子带，在重配周期内，子带是不会发生任何变化的。从图7中可以看出，从下一个重配周期的第一个帧开始，系统就开始使用重配后的子带。重配前的下行子带包括第一子带和第二子带1至第二子带5。重配后的下行子带包括第一子带和第二子带1至第二子带3。重配前后的第二子带1、第二子带2和第二子带3是不相同的。
子带重配是由业务或无线环境变化引起的。比如，某种业务量增加了，其对应传输的子带资源就需要增加以满足业务需求，相反，就可以减少子带带宽，把资源留给其他有需求的业务。另外，无线环境的变化也可能导致子带的重配，以适应环境的变化。
所述重配周期为无线帧的整数倍，且为系统帧号的周期的分数倍。
子带重配必须在该子带重配周期结束的时刻，系统在下一个的子带重配周期开始时按新配置的子带运行。子带重配周期为无线帧长的整数倍，一个无线帧通常为10ms，且为系统帧号的周期的分数倍，一个系统帧号的周期通常包括2048个无线帧，当然，随着需求的增值，也可以扩展为4096个无线帧。
例如：系统帧号的周期为2048个无线帧(也就是系统帧号为0，1，---2047)，那么子带重配周期，可以设置为2048个无线帧，或1024个无线帧，或512个无线帧，或256个无线帧，比如设置为512个无线帧，那么在系统帧号能整除512时，为下一个重配周期的开始位置。
第一子带在重配时变化的通常只有带宽，配置信息中的其他信息通常都保持不变。第二子带和上行子带在重配时，要求子带上没有UE的业务在运行，也就是这个子带是空载的。子带重配的原则是尽量不影响现有用户设备在子带 上的业务。
在子带的下一个重配周期到来前，通过所述第一子带广播子带重配通知消息，并将子带的重配标志位置位，重配标志位置位表示下一个重配周期，子带要进行重配。
在每个子带重配周期结束前的几个无线帧，网络设备通过第一子带开始广播子带重配通知消息，在重配通知消息中携带重配标识位，表示下一个重配周期，子带要进行重配。
对于连接态的用户设备，可以通过单播消息通知用户设备子带重配后的配置信息；也可以通过广播通知子带重配后的配置信息。通过单播的话，可以告诉连接态的用户设备，在子带重配后，它在哪一个或几个子带上去接收对应的业务。如果是广播方式，那么可以通知在本子带下接收业务的用户设备，统一都到指定的重配后的子带上去接收对应的业务；如果单播和多播方式都存在，那么对具体的某个用户设备，以单播通知的方式为准。
对于空闲态的用户设备，用户设备直接在重配周期开始的时候从第一子带接收广播信息，获取重配后的子带的配置信息。
在新的子带重配周期开始时，将所述子带的重配标志位清除，表示系统现在没有进行子带重配了。
若某个用户设备在至少两个子带上有业务，那只需在其中一个子带上向该用户设备通知子带的重配信息。
系统广播是为了让用户设备快速正确的了解当前系统的信息，用于其快速准确的接入无线通信系统，并顺利开展各种系统支持的业务。
分两种情况，一种是UE只能同时接收一个子带；一种是UE可以同时接收多个子带。
UE只能同时接收一个子带的情况：
系统采用两级广播方案：通过第一子带广播第二子带和上行子带的配置信息和全局适用的广播信息，以及本第一子带自身相关的广播信息；
如果第二子带上的UE处于连接态(ACTIVE态)，网络设备则可以在第二子带子带上发送重配后的配置信息，UE在第二子带上接收。这样UE就不需要再 切换到第一子带上去接收更新的系统消息了。
如果第二子带上的UE处于非连接态的，第二子带上会广播主系统消息有更新的消息，UE收到这个消息后，就切换到第一子带上去接收系统消息更新信息，完成系统消息更新后，再切换到从子带上。
UE能同时接收至少2个子带的情况：
那么UE在某个子带进行业务的时候，还能够接收第一子带的广播消息；因此，第一子带广播消息的更新，不需要再从子带上再次发送；
另外，还有一种情况是，UE本身在多个子带上进行业务，没有多余的能力再接收第一子带上的广播信息；这种情况下，要求UE暂时停止某个子带上的业务，去接收第一子带上广播消息的更新。
本发明针对F-OFDM技术的标准化，提供了无线通信系统需要在进行的配合设计方案，通过本方案，能够有效利用F-OFDM的技术价值，提供5G系统灵活的适配不同业务和应用场景的能力。
