具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请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，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、未来的第五代(5th Generation，5G)系统或新无线(New Radio，NR)、物联网(Internet of Things，IoT)系统等。
本申请实施例中的基站，可以是网络设备，网络设备可以是用于与终端设备通信的设备，该网络设备可以是全球移动通讯(Global System of Mobile communication，GSM)系统或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional NodeB，eNB或eNodeB)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，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网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
另外，在本申请实施例中，网络设备为小区提供服务，终端设备通过该小区分配的传输资源(例如，频域资源，或者说，频谱资源)与网络设备进行通信，该小区可以是网络 设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
此外，LTE系统或5G系统中的载波上可以同时有多个小区同频工作，在某些特殊场景下，也可以认为上述载波与小区的概念等同。例如在载波聚合(Carrier Aggregation，CA)场景下，当为UE配置辅载波时，会同时携带辅载波的载波索引和工作在该辅载波的辅小区的小区标识(Cell Indentify，Cell ID)，在这种情况下，可以认为载波与小区的概念等同，比如UE接入一个载波和接入一个小区是等同的。
本申请实施例中的终端设备可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，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网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例对此并不限定。
此外，在本申请实施例中，终端设备还可以是物联网(Internet of Things，IoT)系统中的终端设备，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。
在本申请实施例中，IoT技术可以通过例如窄带(Narrow Band，NB)技术，做到海量连接，深度覆盖，终端省电。网络设备为终端设备分配资源供终端设备进行数据传输，根据本申请实施例的通信方法，能够使得在离散窄带频谱中，终端设备与网络设备在有效载波上进行数据传输。
图1是能够适用本申请实施例通信方法和通信装置的系统100的示意图。如图1所示，该系统100包括网络设备101，网络设备101可以是eNodeB等。网络设备101可包括1个天线或多个天线，网络设备101可附加地包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
网络设备101可以与多个终端设备通信，例如终端设备102。然而，可以理解，网络设备101可以与类似于终端设备102的任意数目的终端设备通信。终端设备102可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
系统100还可以包括核心网103，如，分组核心网络(Evolved Packet Core，EPC)。EPC可以支持3GPP和非3GPP等多种接入方式，是支持异构网络的融合架构。EPC是4G移动通信网络的核心网。它属于核心网范畴，具备用户签约数据存储，移动性管理和数据交换等移动网络的传统能力，并能够给用户提供超高速的上网体验。
如图1所示，网络设备101可以通过UU接口与终端设备102通信，UU接口的功能包括广播寻呼以及无线资源控制(Radio Resource Control，RRC)连接的处理、切换和功 率控制的判决执行、处理无线资源的管理和控制信息、处理基带和射频处理信息等。此外，网络设备102可以通过S1接口与核心网103进行通信。终端设备102通过网络设备，如基站，接入，或者通过路由节点接入，网络设备101连接核心网103完成数据的回传和前向传递。网络设备101可以指网络侧的一种用来发送或接收信号的实体，例如，可以是基站。UE可以是任意的终端，例如，UE可以是机器类通信的用户设备。终端设备110和网络设备120之间支持多业务传输。例如，5G系统中的增强移动宽带业务、超可靠和低时延的机器通信业务以及超大连接的机器通信业务。
此外，该通信系统100可以是PLMN网络、D2D网络、M2M网络、IoT网络或者其他网络，图1只是举例的简化示意图，网络中还可以包括其他网络设备，图1中未予以画出。
对于终端设备与网络设备进行数据传输，网络设备给终端设备分配资源的方式有很多。一种方案是，通过激活半静态调度(Semi-Persistent Scheduling，SPS)。在LTE系统中，终端设备需要使用某个资源或者发送数据时，需要先向基站进行资源申请。只有申请到了时频空资源，才能够发送相应的数据。在通信业务中，有一些业务是有固定的格式，比如语音，通常是20ms一个数据报文。这样可以空口每20ms发送一次。这样就不要每次都进行物理下行控制信道(Physical Downlink Control Channel，PDCCH)的信令交互。如果语音业务将资源给固定分配下来，则业务过程中不再需要将相应的资源信息通知给终端设备，这样就可以节省底层的信令交互的信息。SPS就是这样一种思路，基站首次配置了SPS的资源的调度之后，此调度在整个SPS时间内周期有效，直到SPS的释放，从而基站或者终端设备只需要持续数传即可，不需要再次进行资源分配，于是SPS能够节省PDCCH的资源。
具体地，是否能够进行SPS是由L3来进行控制的，即，L3通过发送携带SPS配置(SPS，Configuration，SPS-Config)的无线资源控制连接重配置(Radio Resource Control Connection Reconfiguration)信令来配置SPS。SPS-Config主要包含三个部分，其中，semi-Persist Scheduling C-RNTI字段表示如果UE收到该C-RNTI加扰的调度，则预示着SPS被激活了；sps-ConfigDL字段是用于指示下行的SPS配置；sps-ConfigUL字段是用于指示上行的SPS配置。
协议并没有规定什么时候需要激活和去激活下行的SPS，但是协议上规定了激活方式，即当终端设备收到使用semi-Persist Scheduling C-RNTI加扰的DL Grant后，需要激活或去激活SPS。同样，协议中并没有规定什么时候需要激活上行的SPS，但是规定了激活方式和去激活方式，即当终端设备收到使用semi-Persist Scheduling C-RNTI加扰的UL Grant后，需要激活或去激活SPS。
SPS机制对于离散频谱来说，可能不是很合适。其中，离散频谱可以是指在一个频段中包括多个载波，该多个载波中有有效载波，也有无效载波。其中，有效载波指的是指能供终端设备与基站进行通信的载波，无效载波是指不能供终端设备与基站进行通信的载波。
以IoT系统为例，在电力系统中，223MHz～235MHz总共存12MHz带宽的专用频谱，230MHz IoT方案上高层协议主要基于R14的NB-IoT技术，物理层基于频谱的特殊限制(例如，每个信道带宽25KHz、离散窄带频谱等特点)进行优化设计。图2示出了230MHz  IoT系统的频谱特点，且图3示出了230MHz的可用频点。
223MHz～235MHz的IoT系统，共12MHz频段，原用于无线电台，对双工方式定义模糊。如图2所示，每25kHz窄带构成一个独立载波，多个连续分布的25kHz载波可以按载波聚合(Carrier Aggregation，CA)方式使用，不允许作为一个宽带载波使用。此外，对于离散频谱来说，例如，230MHz IoT系统，频谱划分方式与LTE系统存在很大的差别。在离散频谱中具体哪个载波是有效载波、哪个载波是无效载波是不清楚的。因此对于离散频谱来说，不能直接沿用LTE系统的SPS机制。本申请实施例主要考虑的是在这种离散频谱下，如何分配资源，如，进行上行资源配置或下行资源配置。
下面，结合图4，对本申请实施例的通信方法100进行详细说明。图4是本申请实施例的通信方法的示意性交互图。图4的方法100包括：
110，基站向终端设备发送第一频段的资源信息。所述第一频段包括第一载波集合和第二载波集合，所述第一频段的资源信息包括所述第一载波集合中的载波标识和/或第二载波集合中的载波标识，其中，所述第一载波集合中的载波能用于所述终端设备与所述基站通信，所述第二载波集合中的载波不能用于所述终端设备与所述基站通信；
120，所述基站基于所述第一频段的资源信息与所述终端设备通信。
通过本申请实施例，可以在离散频谱系统中，使得终端设备确定无效载波，并且在有效载波上进行通信。
第一频段包括多个载波，该多个载波包括有效载波，有效载波代表第一载波集合中的载波；多个载波还包括无效载波，无效载波代表第二载波集合中的载波。
其中，第一载波集合中的载波(即有效载波)能用于所述终端设备与所述基站通信，可以理解为，第一载波集合中的载波是可用于终端设备和基站通信的候选载波的集合，可包括一个或多个载波。所述第二载波集合中的载波(即无效载波)不能用于所述终端设备与所述基站通信，可以理解为，第二载波集合中的载波是不可用于，或者说，被禁止用于，终端设备和基站通信的载波的集合，可包括一个或多个载波。并且，第一载波集合和第二载波集合都可以是预先配置的，例如基站配置等。
基站可以基于终端设备的业务为终端设备确定一个频段，记为频段#A，即可以理解为动态地分配一个频段#A。第一频段可以是频段#A；或者，第一频段包括频段#A，即频段#A为第一频段中的一段。第一频段包括多个载波，图5示出了分配载波的示意图。如图5所示，基站为终端设备从第一频段中分配频段#A，该频段#A包括4个载波，其中包括两个有效载波和两个无效载波。为终端设备分配多少个有效载波或者分配多大的频段，可以基于终端设备的业务确定，此处不作限定。
应理解，上述频段#A仅是为了不失一般性，且便于理解，而进行的一个举例说明。或者，第一频段可以是半静态调度的，也可以是动态调度的，本申请实施例对此不作限定。
应理解，此处的第一载波集合中的载波是有效载波，第二载波集合中的载波是无效载波。第一载波集合中可以包括多个有效载波，第二载波集合中可以包括多个无效载波。
所述第一频段的资源信息包括所述第一载波集合中的载波标识和/或第二载波集合中的载波标识。换句话说，基站向终端设备发送第一频段的资源信息，第一频段的资源信息包括有效载波的标识信息和/或无效载波的标识信息。
无效载波的标识信息用于终端设备确定哪些载波是无效载波，例如，网络设备可以对 无效载波作标识，终端设备根据该标识可确定频段中的无效载波。
有效载波的频段信息用于终端设备确定进行通信的频域信息。
当频段的信息包括有效载波的标识信息时，终端设备可以根据该有效载波的标识信息在有效载波上与基站进行通信。或者，当频段的信息包括无效载波的标识信息时，终端设备可以根据该无效载波的标识信息确定无效载波。或者，当频段的信息包括无效载波的标识信息和有效载波的标识信息时，终端设备不仅可以确定哪些载波是无效载波，而且可以在有效载波上与基站进行通信。
可选地，所述第一频段的资源信息还包括所述第一频段的起始位置的信息；所述基站基于所述第一频段的资源信息与所述终端设备通信，包括：所述基站基于所述第一载波集合中的载波标识和/或第二载波集合中的载波标识，并根据所述第一频段的起始位置的信息，与所述终端设备在第三载波上通信，所述第三载波是所述第一载波集合中的载波。
根据有效载波的标识信息和/或无效载波的标识信息，以及频段的起始位置的信息，终端设备可以确定与基站进行通信的频域资源信息。通过起始位置以及标识信息以确定进行通信的第三载波，可以节省信令。
可选地，所述第一频段的资源信息包括载波数N，所述载波数N为所述基站分配给所述终端设备的载波的数量，其中，N为大于或等于1的整数；以及，所述基站基于所述第一频段的资源信息与所述终端设备通信，包括：所述基站基于所述载波数N和所述第一载波集合中的载波标识，与所述终端设备在N个载波上通信，所述N个载波是所述第一载波集合中的载波。
基站为终端设备分配N个有效载波，根据有效载波的标识，终端设备从有效载波中确定N个有效载波，便于与基站进行通信。根据有效载波的标识和载波绑定数可以确定基站与终端设备进行通信的频域资源，进一步节省信令。应理解，第三载波可以是N个有效载波中的任意一个，也可以是第一载波集合中的任意一个。
载波数，也可称为载波绑定数，或者，称为有效载波数，指的是网络设备为终端设备分配的有效载波的数目。根据载波绑定数和有效载波的标识信息，可以确定N个载波，以便终端设备与基站进行通信。这种确定频段的方式，可以节省开销。
或者，根据第一频段起始位置和载波绑定数也可以确定终端设备与基站进行通信的载频资源。
应理解，该有效载波数指的单个突发脉冲(burst)传输占用的载波的数。
可选地，所述第一频段的资源信息还包括所述基站与所述终端设备通信所占的时域资源信息。
该时域资源信息可以包括帧(frame)绑定数，帧绑定数指的是单个burst传输占用的帧的数目，图6是单个突发脉冲占用帧数的示意图。如图6所示，假设帧绑定数为2、重复传输(repetition Number)的次数为2。那么burst的长度是帧绑定数与重复次数的乘积，即为4个帧。
该时域资源信息还可以包括周期(period)、起始偏置(offset)、持续时间(duration)等。图7示出了传输时间点的配置，其中包括在一个周期内进行数据传输的持续时间和起始偏置。
可选地，所述第一频段的资源信息承载于无线资源控制RRC连接重配置信令中。
为便于理解，首先通过图8介绍一下NB-IoT的接入流程。
810，终端设备向基站发送前导码(preamble)，用于通知基站有一个随机接入请求。
820，基站向终端设备发送反馈信息(response)。具体地，终端设备可以根据接收到的反馈信息确定是否成功接收到自己想要的反馈信息，然后进行后续处理。
830，终端设备向基站RRC连接请求信息。具体地，该RRC连接请求信息携带的信息如下：
(1)如果是初次接入(initial access)，RRC连接请求信息为在公共控制信道(common control channel，CCCH)上传输的RRC连接请求信息，且至少需要携带NAS终端设备标志信息。
(2)如果是RRC连接重建，RRC连接请求信息为CCCH上传输的RRC连接重建请求信息，且不携带任何NAS消息。
(3)如果是切换(handover)，RRC连接请求信息为在专用控制信道(Dedicated Control Channel，DCCH)上传输的经过加密和完整性保护的RRC Handover Confirm，必须包含终端设备的小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)，且如果可能的话，需要携带BSR。
(4)对于其它触发事件，则至少需要携带C-RNTI。
840，基站向终端设备发送RRC连接配置信息。

880，基站向终端设备发送RRC连接重配置信息(RRC Connection Reconfiguration)
890，终端设备向基站发送RRC连接重配置完成信息(RRC Connection Reconfiguration Complete)。
通过将第一载波的信息承载RRC连接重配置信令中，可以节省信令开销。
接下来，通过图9，以为终端设备进行下行资源配置为例说明上述过程。
首先，基站向终端设备发送RRC连接重配置信息，其中包括下行资源配置的参数的信息，该信息可以承载于物理下行共享信道(Physical Downlink Shared Channel，PDSCH)。下行资源配置的参数包括：载波绑定数、起始载波位置、帧绑定数、调制与编码方式索引(modulation and coding scheme Index，mcs-Index)、重复次数、周期、起始偏置、持续时间等，其中，载波绑定数和重复次数指的是占用的频域资源。各个参数具体的含义如前所述，此处不再赘述。
其次，终端设备向基站发送RRC连接重配置完成信息。
需要说明的是，为终端设备进行上行资源配置的过程同上述过程相似，此处不再赘述。
需要说明的是，本申请实施例还可以应用于为终端设备进行免调度传输对应的下行或上行资源配置。
其中，免调度传输可以指：网络设备预先分配并告知终端设备多个传输资源；终端设备有上行数据传输需求时，从网络设备预先分配的多个传输资源中选择至少一个传输资源，使用所选择的传输资源发送上行数据；网络设备在所述预先分配的多个传输资源中的一个或多个传输资源上检测终端设备发送的上行数据。
或，免调度传输可以指：网络设备预先分配并告知终端设备多个传输资源，以使终端设备有上行数据传输需求时，从网络设备预先分配的多个传输资源中选择至少一个传输资源，使用所选择的传输资源发送上行数据。

或，免调度传输可以指：终端设备在不需要网络设备调度的情况下进行上行数据传输。所述调度可以指终端设备发送上行调度请求给网络设备，网络设备接收调度请求后，向终端设备发送上行许可，其中所述上行许可指示分配给终端设备的上行传输资源。
或，免调度传输可以指：一种竞争传输方式，具体地可以指多个终端在预先分配的相同的时频资源上同时进行上行数据传输，而无需基站进行调度。
图10是本申请另一实施例的通信方法的示意图。方法200包括：
210，终端设备接收基站发送的第一频段的资源信息。所述第一频段包括第一载波集合和第二载波集合，所述第一频段的资源信息包括所述第一载波集合中的载波标识和/或第二载波集合中的载波标识，其中，所述第一载波集合中的载波能用于所述终端设备与所述基站进行通信，所述第二载波集合中的载波不能用于所述终端设备与所述基站进行通信；
220，在第三载波上进行通信。也就是说，所述终端设备根据所述第一频段的资源信息，从所述第一载波集合中确定与所述基站通信的载波。

应理解，所述第三载波是所述第一载波集合中的任一载波。
可选地，所述第一频段的资源信息还包括所述第一频段的起始位置的信息；所述根据所述第一频段的资源信息，所述终端设备根据所述第一频段的资源信息，从所述第一载波集合中确定与所述基站通信的载波，包括：所述终端设备根据所述第一载波集合中的载波标识和/或所述第二载波集合中的载波标识，并根据所述第一频段的起始位置的信息，从所述第一载波集合中确定与所述基站通信的载波。

通过本申请实施例的通信方法，可以解决在离散频谱中，混合自动重传请求(Hybrid  Automatic Repeat reQuest，HARQ)反馈资源的问题。
应理解，对于PDSCH传输，需要进行HARQ反馈解调结果。HARQ技术是一种将前向纠错编码(Forward Error Correction，FEC)和自动重传请求(Automatic Repeat Request，ARQ)相结合而形成的技术。
例如，在HARQ技术中，接收端在从发送端接收到数据后，可以确定该数据是否准确译码。如果不能准确译码，则接收端可以向发送端反馈非确认(Negative-acknowledge，NACK)信息，从而，发送端可以基于NACK信息，确定接收端没有准确接收到数据，从而可以进行重传处理；如果能够准确译码，则接收端可以向发送端反馈确认(Acknowledge，ACK)信息，从而，发送端可以基于ACK信息，确定接收端准确接收到数据，从而可以确定完成了数据传输。
即，在本申请实施例中，当终端设备解码成功时可以向网络设备发送ACK信息，在解码失败时可以向网络设备反馈NACK信息。
作为示例而非限定，在本申请实施例中，反馈信息可以包括HARQ技术中的ACK信息或NACK信息。

根据本申请实施例的通信方法，通过使网络设备确定第一频段上的有效载波和无效载波，并把有效载波的信息和/或无效载波的信息发送给终端设备，使得终端设备从离散的载波中确定出有效载波，进一步与网络设备在有效载波上进行通信，从而能够使得终端设备与网络设备有效地通信。
