技术领域
本申请涉及通信领域，并且更具体地，涉及通信领域中传输数据的方法和装置。
背景技术
增强的移动宽带(enhanced Mobile Broadband，eMBB)通信与低时延高可靠性(ultra-reliable low latency communication，URLLC)通信是未来网络系统中的两个重要场景。eMBB能够在现有移动宽带业务场景的基础上，进一步提升系统容量等性能，增强用户体验，eMBB业务主要为3D/超高清视频等大流量移动宽带业务。URLLC业务主要是无人驾驶、工业自动化等需要低时延高可靠连接业务。URLLC业务的数据相比eMBB业务的数据来说，一般数据包较小，例如从几十字节到几百字节。
由于URLLC业务的数据具有随机到达的特性，当采用某一时频资源上行传输eMBB业务的数据时，URLLC业务的数据也可能使用该时频资源进行上行传输，此时URLLC业务的数据和eMBB业务的数据在接收时会产生互相干扰。
发明内容
本申请提供一种传输数据的方法和装置以及传输信息的方法和装置，能够降低在复用相同时频资源进行数据传输的情况下一种数据对另一种数据所产生的干扰。

根据所述传输参数，确定用于对该第一数据进行编码的待编码数据块的大小；
根据所述待编码数据块的大小，对所述第一数据进行编码；
将编码得到的数据块映射到所述时频资源上。
本申请实施例中，TTI表示一次数据传输的时间间隔，同时也是最小的调度周期。在5G中，eMBB业务的数据和URLLC业务的数据通常采用不同大小的TTI进行传输。

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。
图1示出了本申请实施例应用的无线通信系统100。该无线通信系统100可以包括至少一个网络设备，图1中示出了网络设备110，网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。该网络设备110可以是GSM系统或CDMA系统中的基站(base transceiver station，BTS)，也可以是WCDMA系统中的基站(nodeB，NB)，还可以是LTE系统中的演进型基站(evolved node B，eNB或eNodeB)，或者是云无线接入网络(cloud radio access network，CRAN)中的无线控制器。该网络设备还可以为中继站、接入点、车载设备、可穿戴设备、未来5G网络中的网络侧设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的网络设备等。
该无线通信系统100还包括位于网络设备110覆盖范围内的多个终端设备，图1中示出了终端设备120和终端设备130。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该无线通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。可选地，该无线通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例不限于此。
应理解，在本申请实施例中，终端设备可以是移动的或固定的。该第一终端设备120和该第二终端设备130可以指接入终端、用户设备(user equipment，UE)、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等。接入终端可以是蜂窝电话、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PLMN中的终端设备等。
本申请实施例中，TTI表示一次数据传输的时间间隔，同时也是最小的调度周期。在5G中，eMBB业务的数据和URLLC业务的数据通常采用不同的TTI大小进行传输。为便于理解，在本申请中将“eMBB业务的数据”简称为“eMBB数据”，将“URLLC业务的数据”简称为“URLLC数据”。
在本申请实施例中，数据传输设备可以传输eMBB数据和/或URLLC数据，由于URLLC数据的数据包通常比eMBB数据的数据包小，因此，eMBB的TTI通常大于或等于URLLC的TTI。
本申请实施例中，数据发送设备在一个TTI内传输的数据数据块，称为传输块(transmit block，TB)，该传输块的大小称为传输块大小(transmit block size，TBS)，对一个TTI内的传输块进行调制编码后可以得到编码块(code block，CB)。
数据发送设备在发送数据之前可以获知待传输的传输块的调制编码方案(modulation and coding，MCS)编号和预分配的物理资源块编号，根据该MCS编号可以查询得到对应的TBS编号，并获得与该TBS编号对应的TBS表格，并根据该物理资源块的数量从TBS 表格中查到TBS，并根据该TBS确定待传输的TB，根据该TB的MCS对该TB进行调制编码得CB，然后将该CB映射到该物理资源块编号对应的物理资源上。
另外，在现有技术技术中，如果数据接收设备在分配的物理资源上接收eMBB CB的过程中，存在其它设备复用该物理资源的部分或全部传输了URLLC CB，由于该数据接收设备在物理资源的复用部分上接收eMBB数据时受到URLLC数据的干扰，导致接收到的eMBB数据的编码块受到URLLC数据的编码块的干扰，现有技术中eMBB的编码块大小是远大于URLLC数据的编码块大小，就导致了较小的URLLC的编码块对较大的eMBB数据的数据块的干扰，因此，对接收到的eMBB数据的编码块进行译码时会产生比较高的误码率。
本申请实施例的数据传输方法，数据发送设备能够按照URLLC数据的传输情况，确定eMBB数据的待编码数据块大小，并根据eMBB数据的待编码数据块大小对eMBB数据进行编码和映射，那么在物理资源的复用部分上eMBB数据的待编码数据块大小能较好的匹配URLLC数据的待编码数据块大小。因此，数据接收设备在对eMMB数据进行译码时，URLLC数据对eMBB数据的干扰就被限制在较小的数据范围内，从而降低了URLLC数据对eMBB数据的干扰。
此外，在对URLLC数据的编码块进行译码时，需要读取对该编码块产生干扰的eMBB数据的编码块，由于在物理资源的复用部分上eMBB数据的待编码数据块大小能较好的匹配URLLC数据的待编码数据块大小，eMBB数据的编码块大小也就能较好的匹配URLLC数据的编码块大小，从而降低了在对URLLC数据的编码块进行译码时产生的译码时延。
图2示出了本申请实施例提供的传输数据的方法200的示意性流程图，该方法200例如可以应用于如图1所示的无线通信系统，应理解，该方法200可以由数据发送设备执行。
S210，获取用于传输第一数据的时频资源，其中，所述时频资源中有部分资源或者全部资源也被用于传输第二数据。
S220，获取传输所述第二数据所使用的传输参数。
S230，根据所述传输参数，确定用于对所述第一数据进行编码的待编码数据块的大小。
S240，根据所述待编码数据块的大小，对所述第一数据进行编码。
S250，将编码得到的数据块映射到所述时频资源上。
应理解，本申请实施例的传输数据的方法，既可以用于上行数据传输的场景，也可以用于下行数据传输的场景，在上行数据传输的场景下，该数据发送设备可以为终端设备，在下行数据传输的场景下，该数据发送设备可以为网络设备。还应理解，本申请实施例中的第一数据可以为eMBB数据，第二数据可以为URLLC数据，该第一数据和该第二数据可以通过同一个数据发送设备传输，也可以通过不同的发送设备传输。
在本申请实施例中，待编码数据块可以是TB，也可以是将TB分割得到的用于输入到编码器的数据块。
本申请实施例的数据传输方法，数据发送设备能够按照URLLC数据的传输情况，确定eMBB数据的待编码数据块大小，并根据eMBB数据的待编码数据块大小对eMBB数据进行编码和映射，那么在物理资源的复用部分上eMBB数据的待编码数据块大小能较好的匹配URLLC数据的待编码数据块大小。因此，数据接收设备在对eMMB数据进行译码时，URLLC数据对eMBB数据的干扰就被限制在较小的数据范围内，从而降低了URLLC 数据对eMBB数据的干扰。
另外，在对URLLC数据的编码块进行译码时，需要读取对该编码块产生干扰的eMBB数据的编码块，由于在物理资源的复用部分上eMBB数据的待编码数据块大小能较好的匹配URLLC数据的待编码数据块大小，eMBB数据的编码块大小也能较好的匹配URLLC数据的编码块大小，从而降低了在对URLLC数据的编码块进行译码时产生的译码时延。
可选地，S220中的传输参数可以包括传输所述第二数据所使用的待编码数据块的大小、用于传输所述第二数据的TTI的数量、每个所述TTI的大小、每个所述TTI内用于传输所述第二数据的第一频率资源、每个所述TTI中控制信道所占用的时频资源和每个所述TTI中导频所占用的时频资源中的至少一种，本申请实施例对此不作限定。
本申请实施例提供的传输数据的方法，根据用于传输所述第二数据的TTI的数量、每个所述TTI的大小、每个所述TTI内用于传输所述第二数据的第一频率资源、每个所述TTI中控制信道所占用的时频资源和每个所述TTI中导频所占用的时频资源中的至少一种，确定的用于对所述第一数据进行编码的待编码数据块的大小，实际上较好的匹配了传输所述第二数据所使用的待编码数据块的大小，并根据该待编码数据块的大小对第一数据进行编码和映射，使得在接收eMBB数据时将URLLC数据对eMBB数据的干扰限制在较小的数据范围内，也可以降低在接收URLLC数据时的译码时延。
作为一个可选实施例，该传输参数可以包括传输该第二数据所使用的待编码数据块的大小，数据发送设备可以根据该第二数据所使用的待编码数据块的大小，确定用于对该第一数据进行编码的待编码数据块的大小。
可选地，在本申请实施例中，每个所述TTI内用于传输第一数据的第一频率资源可以全部被用于传输第二数据，也可以部分被用于传输第二数据，本申请实施例对此不作限定。
作为一个可选实施例，所述传输参数可以包括每个所述TTI的大小和每个所述TTI内用于传输所述第二数据的第一频率资源，数据发送设备可以根据每个所述TTI的大小和每个所述TTI内用于传输所述第二数据的第一频率资源，确定每个所述TTI对应的待编码数据块的大小，并根据每个所述TTI对应的待编码数据块的大小，确定用于对第一数据进行编码的待编码数据块的大小。
作为另一个可选实施例，若每个所述TTI内用于传输第一数据的第一频率资源部分被用于传输第二数据，所述传输参数可以包括用于传输所述第二数据的TTI的数量、每个所述TTI的大小和每个所述TTI内用于传输所述第二数据的第一频率资源，所述数据发送设备可以根据每个所述TTI内用于传输所述第二数据的第一频率资源，确定所述时频资源中未被用于传输所述第二数据的第二频率资源，根据所述第二频率资源和所述时频资源所对应的TTI，确定用于对所述第一数据中利用所述第二频率资源进行传输的数据进行编码的待编码数据块的大小，并根据每个所述TTI对应的待编码数据块的大小和所述用于对所述第一数据中利用所述第二频率资源进行传输的数据进行编码的待编码数据块的大小，确定所述用于对第一数据进行编码的待编码数据块的大小。
作为又一个可选实施例，若用于传输所述第二数据的TTI占满第一数据的时域资源，则所述传输参数可以包括所述TTI的大小，相应地，数据发送设备可以根据所述TTI的大小，确定所述用于对所述第二数据进行编码的待编码数据块的大小，并根据用于对所述第二数据进行编码的待编码数据块的大小，确定用于对所述第一数据进行编码的待编码数据 块的大小。
可选地，数据发送设备可以通过不同的方式确定该TTI中第i个TTI所对应的待编码数据块的大小，下面将详细介绍本申请实施例中，数据发送设备确定第i个TTI所对应的待编码数据块的大小的方法。
作为一个可选实施例，数据发送设备可以根据该TTI中第i个TTI内用于传输该第二数据的第一频率资源，确定当该第i个TTI对应基准TTI大小，该基准TTI对应的待编码数据块的大小，i为大于0的整数；根据该基准TTI对应的待编码数据块的大小和该第i个TTI的大小，确定该第i个TTI所对应的待编码数据块的大小。
例如，该数据发送装置可以根据该第i个TTI内用于传输该第二数据的MCS索引，确定当该第i个TTI对应基准TTI的大小时，该第i个TTI内用于传输该第二数据的TBS索引，并获取TBS表格，第i个TTI内用于传输该第二数据的第一频率资源，在该TBS表格中查找该基准TTI对应的待编码数据块的大小，再根据该基准TTI对应的待编码数据块的大小和该第i个TTI的大小，折算出该第i个TTI所对应的待编码数据块的大小。
表1示出了基准TTI对应的TBS表格。应理解，该基准TTI的大小例如可以为14个符号。

1 TBS(bit) 16 32 56 88 120 152 176 208 224 ……

例如，假设该基准TTI的大小为14个符号，与基准TTI对应的TBS为224bit，该第i个TTI的大小为2个符号，则该第i个TTI对应的待编码数据块的大小可以为floor(224*2/14)。

另外，假设图4中一个频带为一个复用区域，以复用区域1为例，该第二消息用于指示在频带1上传输第二数据采用的帧结构。该第二消息例如可以携带频带1上包括5个TTI、每个TTI的大小和每个所述TTI的起始位置。如图5所示，在频带1上，用于传输第一数据的第一TTI包括编号0到13的14个符号，该第一TTI包括5个用于传输第二数据的TTI，第一个TTI包括编号为2、3、4的3个符号，第二个TTI包括编号为5、6的2个符号，第三个TTI包括编号为7、8、9的3个符号，第四个TTI包括编号为10、11的2个符号，第五个TTI包括编号为12、13的2个符号，其中，该第一TTI中编号为0、1的2个符号用于传输该第一数据的导频和/或控制信道。同理可知复用区域2、复用区域3与复用区域4中的帧结构，此处不再赘述。

例如，如图5中一个TTI对应一个复用区域，例如复用区域1中，TTI 1的跳频信息用于指示第一终端设备在TTI 1占用频带1，在TTI 2占用频带2，在TTI 3占用频带3，在TTI 4占用频带4。例如复用区域2中，TTI 2的跳频信息用于指示第一终端设备在TTI1占用频带4，在TTI 2占用的频带1，在TTI 3占用频带2，在TTI 4占用频带3。同理可知复用区域3与复用区域4的跳频信息指示的时频信息的分布，此处不再赘述。
可选地，本申请实施例上述两种传输参数的指示方法中，第二消息信息还可以携带每个所述TTI中控制信道所占用的时频资源和/或每个所述TTI中导频所占用的时频资源。相应地，用于传输第一数据的设备可以根据第二消息获知每个所述TTI中控制信道所占用的时频资源和/或每个所述TTI中导频所占用的时频资源。
可选地，导频可以位于TTI的首个符号或者非首个符号，且导频所占用的带宽可以为该导频所在符号对应的全部带宽或者部分带宽，本申请实施例对此不作限定。

可选地，由于第一消息指示的周期长且指示的信息变化慢，可以静态配置，因此该第一消息可以为高层控制消息，该高层控制消息例如可以为SI或者RRC消息，本申请实施例对此不作限定。
可选地，由于第二消息指示的周期短且指示的信息变化快，需要动态指示，因此该第二消息可以为底层控制消息，该底层控制消息例如可以为DCI或者CFI消息，本申请实施例对此不作限定。
本申请实施例的传输数据的方法，第二消息信息携带每个所述TTI中控制信道所占用的时频资源和/或每个所述TTI中导频所占用的时频资源，以便于在传输第一数据的时候可以避开第二数据的导频和/或控制信道占用的符号，避免影响第二数据的正常传输。
本申请实施例还提供了另一种数据传输的方法，该方法用于数据接收端接收数据，该数据接收端可以为终端设备，也可以为网络设备，本申请实施例对此不作限定。
作为一个可选实施例，该数据接收设备可以获取用于传输第一数据的时频资源，其中，所述时频资源中有部分资源或者全部资源也被用于传输第二数据，获取传输所述第二数据所使用的传输参数，根据所述传输参数，确定用于对所述第一数据进行译码的待译码数据块的大小，根据所述待译码数据块的大小，通过所述时频资源接收所述第一数据的待译码数据块。
应理解，数据接收设备接收的待译码数据块可以理解为数据发送设备对待编码数据块进行编码后得到的数据块。
可选地，传输参数可以包括传输所述第二数据所使用的待编码数据块的大小、用于传输所述第二数据的TTI的数量、每个所述TTI的大小、每个所述TTI内用于传输所述第二数据的第一频率资源、每个所述TTI中控制信道所占用的时频资源和每个所述TTI中导频所占用的时频资源中的至少一种，本申请实施例对此不作限定。
作为一个可选实施例，所述传输参数可以包括传输所述第二数据所使用的待编码数据块的大小、数据接收设备可以根据传输所述第二数据所使用的待编码数据块的大小，确定用于对所述第一数据进行译码的待译码数据块的大小，并根据所述待译码数据块的大小，通过所述时频资源接收所述第一数据的待译码数据块，并对接收到的待译码数据块进行译码。
作为另一个可选实施例，所述传输参数可以包括用于传输所述第二数据的TTI的数量、每个所述TTI的大小和每个所述TTI内用于传输所述第二数据的第一频率资源，数据接收设备可以根据每个所述TTI的大小和每个所述TTI内用于传输所述第二数据的第一频率资源，确定每个所述TTI对应的待编码数据块的大小，并将每个所述TTI对应的待编码数据块的大小，作为用于对第一数据进行译码的待译码数据块的大小。
本申请实施例的数据传输方法，由于数据发送设备按照URLLC数据的传输情况，确定eMBB数据的待编码数据块大小，并根据eMBB数据的待编码数据块大小对eMBB数据进行编码和映射，那么在物理资源的复用部分上eMBB数据的待编码数据块大小能较好的匹配URLLC数据的待编码数据块大小。因此，数据接收设备在对eMMB数据进行译码时，URLLC数据对eMBB数据的干扰就被限制在较小的数据范围内，从而降低了URLLC数据对eMBB数据的干扰。
此外，在对URLLC数据的编码块进行译码时，需要读取对该编码块产生干扰的eMBB数据的编码块，由于在物理资源的复用部分上eMBB数据的待编码数据块大小能较好的匹配URLLC数据的待编码数据块大小，eMBB数据的编码块大小也能较好的匹配URLLC数据的编码块大小，从而降低了在对URLLC数据的编码块进行译码时产生的译码时延。
