Description

传输数据的方法、网络设备和终端设备 技术领域
本发明涉及通信领域，并且更具体地，涉及一种传输数据的方法、网络设备和终端设备。
背景技术
在第五代移动通信技术(5G)技术中，用户设备(User Equipment，简称“UE”)可以在一个载波内支持多种不同的基础参数集(numerology)。这些不同的基础参数集可以通过频分复用(Frequency Division Multiplex，简称“FDM”)的方式进行复用。在同一个传输时间间隔(Transmission Time Interval，简称“TTI”)中，不同的频域资源可以分配给基于不同基础参数集的数据传输使用。例如对于长期演进(Long Term Evolution，简称“LTE”)系统而言，子载波(subcarrier)带宽是15kHz，符号(symbol)宽度是1/14ms。而5G通信系统和4G通信系统最大的不同之处就在于5G系统可以支持基于不同基础参数集的数据传输，5G的终端也可以支持基于不同基础参数集的数据传输，例如目前5G系统的子载波带宽可以是15*2n Hz(n为非负整数)。
基于不同基础参数集的数据传输可以位于不同的频带(band)上，但是这样会降低5G系统的灵活性，复用不同的基础参数集可以为5G系统带来最大的灵活性，但是当复用不同的基础参数集时，基于不同基础参数集的数据传输的传输过程之间，可能会产生相互干扰。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
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“GSM”)系统、码分多址(Code Division Multiple Access，简称“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access，简称“WCDMA”)系统、通用分组无线业务(General Packet Radio Service，简称“GPRS”)、长期演进(Long Term Evolution，简称“LTE”)系统、通用移动通信系统(Universal Mobile Telecommunication System，简称“UMTS”)、等目前的通信系统，以及，尤其应用于未来的5G系统。
本发明实施例中的终端设备也可以指用户设备(User Equipment，简称“UE”)、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。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，简称“SIP”)电话、无线本地环路(Wireless Local Loop，简称“WLL”)站、个人数字处理(Personal Digital Assistant，简称“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，简称“PLMN”)中的终端设备等。
本发明实施例中的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GSM或CDMA中的基站(Base Transceiver Station，简称“BTS”)，也可以是WCDMA系统中的基站(NodeB，简称“NB”)，还可以是LTE系统中的演进型基站(Evolutional NodeB，简称“eNB或eNodeB”)，还可以是云无线接入网络(Cloud Radio Access Network，简称“CRAN”)场景下的无线控制器，或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未来演进的PLMN网络中的网络设备等。
图1是本发明一个应用场景的示意图。图1中的通信系统可以包括网络设备10和终端设备20。网络设备10用于为终端设备20提供通信服务并接入核心网，终端设备20通过搜索网络设备10发送的同步信号、广播信号等而接入网络，从而进行与网络的通信。图1中所示出的箭头可以表示通过终端设备20与网络设备10之间的蜂窝链路进行的上/下行传输。本发明实施例通过使用不同的DCI格式对基于不同基础参数集的数据传输进行调度，能够 提高控制信令设计的灵活性。
图2示出了根据本发明实施例的传输数据的方法的流程交互图。图2中示出了网络设备10和终端设备20。如图2所示，该传输数据的具体流程包括：
210，网络设备10确定用于传输所述数据的基础参数集和目标频带。
其中，该目标频带包括用于传输该数据的传输频带和保护频带，终端设备20不在所述保护频带上传输所述数据。该保护频带的高频端和低频端分别与基于不同基础参数集传输的数据所使用的传输频带相邻，终端设备不会在此区域内发送和接收5G信号。
具体而言，为了防止使用不同基础参数集的数据的传输过程之间相互干扰，当基于不同基础参数集传输的信号在频域上相邻时，即采用FDM的方式进行复用时，可以在原本相邻的两个频带之间插入该保护频带(guard tone/guard subcarrier)，终端设备在该保护频带上不传输数据，使该保护频带能够用于隔离基于不同基础参数集的数据传输所使用的频带。
举例来说，图3示出了没有保护频带和存在保护频带时基于不同基础参数集的数据传输的示意图。以图3为例，当没有保护频带时，使用不同基础参数集的数据的在相邻频带上传输时，很容易产生相互干扰，例如图3所示，在两个相邻频带上进行数据传输时所使用的子载波间隔(subcarrier spacing)分别为30kHz和15kHz时，在这两个相邻的频带上分别使用这两种子载波间隔的数据的传输过程中，相邻两频带上使用不同子载波间隔传输数据时出现了干扰。但是存在保护频带时，例如图3所示，在两个不同频带上传输的数据所使用的子载波间隔分别为30kHz和15kHz，在这两个频带上分别使用这两种子载波间隔的进行数据传输的过程中，使用不同基础参数集传输的数据所占用的这两个频带被保护频带间隔开，该保护频带上不进行数据传输，从而不会产生不同子载波间隔之间的相互干扰，图3(b)中所示的保护频带的带宽为60kHz。
因此，本发明实施例所述的方法，通过在为终端设备配置的传输资源中设置保护频带，避免了基于不同基础参数集的数据传输之间产生的相互干扰。
可选地，所述目标频带的信息包括所述目标频带的起始位置和终止位置、所述保护频带在所述目标频带中的位置和所述保护频带的带宽。
具体地，网络设备10在为终端设备20配置上下行传输的资源时，发送的配置信息中需要包括用于传输该数据的基础参数集和用于传输该数据的目标频带的信息，其中，用于传输该数据的目标频带的位置可以用该目标频带的起始位置和终止位置来表示，该起始位置和终止位置所限定的目标频带中包括该保护频带，该目标频带的信息还包括该保护频带在该目标频带中所占的位置。
可选地，所述保护频带在所述目标频带中的位置包括所述目标频带的低频端或高频端，或者包括所述目标频带的低频端和高频端。
具体地，网络设备10可以按照下述保护频带与目标频带之间的四种位置关系，为终端设备20分配上下行传输所使用的频域资源。即：保护频带位于目标频带的低频端；保护频带位于目标频带的高频端；保护频带同时位于目标频带的高频端和低频端；目标频带的两端都没有保护频带。
其中，如果该传输频带上传输的数据所使用的基础参数集，与和该目标频带的低频端相邻的频带上传输的数据所使用的基础参数集不同，那么保护频带可以设置于目标频带的低频端；如果该传输频带上传输的数据所使用的基础参数集，与和该目标频带的高频端相邻的频带上传输的数据所使用的基础参数集不同，那么保护频带可以设置于目标频带的高频端；如果该传输频带上传输的数据所使用的基础参数集，与和该目标频带的低频端相邻的频带上传输的数据所使用的基础参数集不同，且该传输频带上传输的数据所使用的基础参数集，与和该目标频带的高频端相邻的频带上传输的数据所使用的基础参数集也不同，那么保护频带可以同时设置于目标频带的低频端和高频端；如果该传输频带上传输的数据所使用的基础参数集，与和该目标频带的低频端相邻的频带上传输的数据所使用的基础参数集相同，且该传输频带上传输的数据所使用的基础参数集，与和该目标频带的高频端相邻的频带上传输的数据所使用的基础参数集相同，那么两个相邻频带之间可以没有保护频带。该目标频带的信息包括该保护频带在该目标频带中的位置，即包括该保护频带所使用的位置关系是上述四种位置关系中的哪一种。
应理解，该保护频带的信息中，也可以包括所述目标频带的起始位置和终止位置、以及所述保护频带的起始位置和终止位置。其中，该保护频带的起始位置和终止位置所形成的该保护频带可以位于目标频带的低频端和/或高频端。如果该保护频带同时位于目标频带的低频端和高频端，该目标频带 的信息中应同时包括位于低频端的那部分保护频带的起止位置，和位于高频端的那部分保护频带的起止位置。
可选地，所述保护频带的带宽为所述网络设备10所支持的最小子载波间隔的整数倍。
具体地，该目标频带的信息中还包括该保护频带的带宽。由于5G系统中同一载波上支持不同的基础参数集，因此该保护频带的带宽要能覆盖基于不用基础参数集的数据传输所使用的频带。所以网络设备10在确定该保护频带的带宽时，要以网络设备10所支持的最小的载波间隔为单位。以图3所示为例，该通信系统支持内15kHz和30kHz这两种子载波间隔，网络设备10在确定该保护频带的带宽时，应以15kHz作为基本单位，也就是说，该保护频带的带宽应为15kHz的整数倍且小于目标频带的带宽。如果该保护频带同时位于目标频带的低频端和高频端，那么位于低频端的那部分保护频带的起止位置和位于高频端的那部分保护频带的带宽都应为15kHz的整数倍。
应理解，网络设备10向终端设备20发送的配置信息中，该目标频带的信息也可以包括该目标频带的起始位置和终止位置，以及保护频带的起始位置和终止位置。
可选地，所述基础参数集包括子载波间隔。
其中，子载波间隔指相邻子载波之间的频率间隔，例如15kHz、60kHz等。该基础参数集中的参数这里包括但不限于子载波间隔，例如网络设备10向终端设备20发送的配置信息中包括的基础参数集中，也可以包括其他参数，例如特定带宽下的子载波数目、物理资源块(Physical ResourceBlock，简称“PRB”)中的子载波数、正交频分复用(Orthogonal FrequencyDivision Multiplexing，简称“OFDM”)符号的长度、用于生成OFDM信号的傅里叶变换例如快速傅里叶变换(Fast Fourier Transform，简称“FFT”)或傅里叶逆变换例如快速逆傅里叶变换(Inverse Fast Fourier Transform，简称“IFFT”)的点数、传输时间间隔TTI中的OFDM符号数、特定时间长度内包含的TTI的个数和信号前缀的长度等。
下面举例说明网络设备10确定的用于传输所述数据的基础参数集和目标频带。假设网络设备10分别为终端设备20和终端设备30配置用于传输上行数据的传输资源。网络设备10为终端设备20配置的用于传输上行数据 的子载波间隔为60kHz，为终端设备30配置的用于传输上行数据的子载波间隔为30kHz，且网络设备10为终端设备20配置的用于传输该上行数据的目标频带的起始位置和终止位置分别为1800kHz和1860kHz，网络设备10为终端设备30配置的用于传输该上行数据的目标频带的起始位置和终止位置分别为1860kHz和2000kHz。由于终端设备20所使用的子载波间隔和终端设备30所使用的子载波间隔不相同，且终端设备20用于传输其上行数据的频带的高频端，与终端设备30用于传输其上行数据的频带的低频端之间相邻，因此，网络设备10可以在为终端设备20配置的目标频带的高频端设置保护频带，或者在为终端设备30配置的目标频带的低频端设置保护频带。假设通信系统中所支持的最小的子载波间隔为30kHz，那么该保护频带的带宽为30kHz的整数倍。例如网络设备10为终端设备20配置的保护频带可以位于为其配置的目标频带的高频端，且保护频带的带宽例如可以为30kHz，即该保护频带的起始位置和终止位置分别为1830kHz和1860kHz；又例如网络设备10为终端设备30配置的保护频带可以位于为其配置的目标频带的低频端，且保护频带的带宽例如可以为60kHz，即该保护频带的起始位置和终止位置分别为1860kHz和1920kHz。
应理解，该目标频带中的用于传输该数据的传输频带，可以是连续的，也可以是不连续的。该目标频带中没有用于传输该数据且不属于保护频带的那部分频带资源，可以用于其它数据的传输等。本发明对此不做限定。
220，网络设备10向终端设备20发送配置信息。
其中，该配置信息包括该基础参数集和该目标频带的信息。
具体而言，网络设备10确定好了用于传输所述数据的基础参数集和目标频带后，向终端设备20发送包括该基础参数集和该目标频带的配置信息，以使得终端设备20根据该配置信息，使用该基础参数集，在该目标频带中的用于传输该数据的频带上，与网络设备10进行该数据传输。
230，终端设备20接收网络设备10发送的配置信息。
具体而言，网络设备10向终端设备20发送配置信息，终端设备20接收到该网络设备10发送的该配置信息后，可以根据该配置信息中的基础参数集，在该配置信息指示的频带上，与网络设备10进行数据传输。
可选地，该配置信息还可以包括与所述基础参数集对应的滤波方式。
具体地，如果该配置信息中还包括与该基础参数集对应的滤波方式，那 么终端设备20可以根据该配置信息指示的滤波方式，对接收到的或者待发送的数据进行滤波。
这时，网络设备10向终端设备20发送配置信息之前，即执行220前，该方法还包括：网络设备10确定与所述基础参数集对应的所述滤波方式。
可选地，该滤波方式包括以下中的至少一种：基带滤波器(可以简称为“滤波器”)的类型、所述基带滤波器的参数、所使用的滤波波形和所述滤波波形的参数。
图4示出了根据本发明另一实施例的数据传输的方法的流程交互图。图4中示出了网络设备10和终端设备20。如图4所示，该传输数据的具体流程包括：
310，网络设备10确定用于传输所述数据的基础参数集、用于传输所述数据的传输频带和与所述基础参数集对应的滤波方式。
具体而言，如果基于不同基础参数集进行传输的数据所使用的频带相邻时，为了防止在频分复用时不同基础参数集之间产生的干扰，网络设备10可以根据该基础参数集，为终端设备20配置与该基础参数集对应的合适的滤波方式，例如滤波器(filter)类型和/或波形(waveform)，以减少基于不同基础参数集的数据传输之间产生的相互干扰。其中，该滤波器的类型和该波形可以是系统中预先规定好的。
因此，通过对基于不同基础参数集传输的数据使用不同的滤波方式进行处理，可以减小基于不同基础参数集的数据传输之间产生的相互干扰。
可选地，该滤波方式可以包括以下中的至少一种：基带滤波器的类型、所述基带滤波器的参数、所使用的滤波波形和所述滤波波形的参数。
具体地，网络设备10为终端设备20配置用于传输该数据的基础参数集和传输频带，还为终端设备20配置与该基础参数集对应的用于对该数据进行滤波的滤波方式。使用不同基础参数集的数据在进行滤波时可以使用不同的滤波器，也可以使滤波器用同一种滤波器但是使用该滤波器时所用的参数不同，或者使用不同的滤波波形，或者同一种滤波波形的不同参数。
在5G系统中，基于不同的基础参数集传输的数据，在基带处理过程中，可能需要与不同的波形或滤波器配合使用。例如，常见的与正交频分复用(Orthogonal Frequency Division Multiplexing，简称“OFDM”)信号配合使用的波形有w-OFDM(windowing OFDM)，f-OFDM(filtered OFDM)。以 w-OFDM为例，OFDM信号产生后在时域上要乘以一个窗函数，譬如常用的升余弦窗w(n)＝0.5{1-cos[2*pi*n/(N-1)]}，其中，n为时域采样时间，N为可配置的参数，上式所列窗函数也可以理解为一个时域的滤波器，N为滤波器参数。
举例来说，网络设备10为终端设备20配置的用于传输上行数据的子载波间隔为60kHz、滤波波形为w-OFDM、传输频带为1800kHz-1830kHz，为终端设备30配置的用于传输下行数据的子载波间隔为30kHz、滤波波形为f-OFDM、传输频带为1920kHz-2000kHz。那么，终端设备20根据网络设备10为其发送的配置信息后，终端设备20根据w-OFDM波形对待发送的上行数据进行处理，并使用30kHz的子载波间隔，在频带1800kHz-1830kHz上向网络设备10发送该上行数据。而终端设备30根据网络设备10为其发送的配置信息后，终端设备30根据30kHz的子载波间隔，在频带1920kHz-2000kHz上接收网络设备10发送该下行数据，并根据f-OFDM波形对接收到的该数据进行处理。
可选地，在310中，网络设备10可以确定用于传输所述数据的基础参数集、用于传输所述数据的传输频带和与所述基础参数集对应的滤波方式，网络设备10还可以确定与该传输频带相邻的保护频带。其中，该保护频带的一端与该传输频带相邻，且该保护频带上不允许终端设备20传输所述数据，以隔离用于传输该数据的该传输频带，和与该保护频带的另一端相邻的传输频带。
320，网络设备10向终端设备20发送配置信息。
其中，该配置信息包括用于传输所述数据的基础参数集、用于传输所述数据的传输频带和与所述基础参数集对应的滤波方式。
具体而言，网络设备10确定用于传输所述数据的用于传输所述数据的基础参数集、用于传输所述数据的传输频带和与所述基础参数集对应的滤波方式后，向终端设备20发送包括用于传输该数据的该传输频带、该基础参数集、和该滤波方式的配置信息，以使得终端设备20根据该配置信息，使用该滤波方式对该数据进行滤波，并使用该基础参数集，在该传输频带上，与网络设备10进行该数据的传输。
可选地，所述配置信息中还可以包括与该传输频带相邻的保护频带的信息。其中，该保护频带的信息可以包括该保护频带和该传输频带的位置关系， 以及该保护频带的带宽。该保护频带和该传输频带的位置关系可以包括：该保护频带与该传输频带的低频端相邻和/或该保护频带与该传输频带的高频端相邻。
330，终端设备20接收网络设备10发送的配置信息。
具体而言，网络设备10向终端设备20发送配置信息，终端设备20接收到该网络设备10发送的该配置信息后，可以根据该滤波方式对该数据进行滤波，并根据该配置信息中的基础参数集，在该配置信息指示的频带上，与网络设备10进行该数据的传输。
可选地，根据图2和图4所示的传输数据的方法，如图5所示的本发明另一实施例的传输数据的方法，在230或330之后，该方法还可以包括411和421。
411，网络设备10根据该配置信息，向终端设备20发送该数据。
具体地，网络设备10可以根据该基础参数集中的参数，在该目标频带中的用于传输该数据的频带上，向终端设备20发送该数据。
421，终端设备20根据该配置信息，接收网络设备10发送的该数据。
具体地，终端设备20根据该基础参数集中的参数，在该目标频带中的用于传输该数据的频带上，接收网络设备10发送的该数据。

431，终端设备20根据该滤波方式对接收到的该数据进行处理。
具体地，终端设备20根据网络设备10发送的配置信息中所指示的滤波方式例如合适的基带滤波器类型或滤波波形，对接收到的该数据进行滤波处理。
可选地，411和421还可以分别由图6中所示的412和422替代，图6是本发明另一实施例的传输数据的方法的流程交互图。
412，终端设备20根据该配置信息，向网络设备10发送该数据。
具体地，终端设备20可以根据该基础参数集中的参数，在该目标频带中的用于传输该数据的频带上，向网络设备10发送该数据。

具体地，终端设备20根据网络设备10发送的配置信息中所指示的滤波方式例如合适的基带滤波器类型或滤波波形，对待发送的该数据进行滤波处理，并向网络设备发送处理后的该数据。
应理解，当前终端设备20与网络设备10之间传输的该数据可以包括上行数据或下行数据，如果传输的该数据是下行数据，网络设备10向终端设备20发送该数据，该配置信息为用于调度下行数据的配置信息，网络设备10向终端设备20发送下行数据后，终端设备20根据该配置信息，正确接收网络设备10发送的该下行数据，即执行411和421；如果传输的该数据是上行数据，终端设备20向网络设备30发送该数据，该配置信息为用于调度上行数据的配置信息，终端设备20根据该配置信息，向网络设备10发送上行数据，网络设备10接收终端设备20发送的该上行数据，即执行412和422。
