具体实施方式
现在参照附图描述多个实施例，其中用相同的附图标记指示本文中的相同元件。在下面的描述中，为便于解释，给出了大量具体细节，以便提供对一个或多个实施例的全面理解。然而，很明显，也可以不用这些具体细节来实现所述实施例。在其它例子中，以方框图形式示出公知结构和设备，以便于描述一个或多个实施例。
在本说明书中使用的术语"部件"、"模块"、"***"等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如，部件可以是但不限于，在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。通过图示，在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程和/或执行线程中，部件可位于一个计算机上和/或分布在2个或更多个计算机之间。此外，这些部件可从在上面存储有各种所述数据结构的各种计算机可读介质执行。部件可例如根据具有一个或多个所述数据分组(例如来自与本地***、分布式***和/或网络间的另一部件交互的二个部件的所述数据，例如通过信号与其它***交互的互联网)的信号通过本地和/或远程进程来通信。
此外，结合接入终端设备描述了各个实施例。接入终端设备也可以称为***、用户单元、用户站、移动站、移动台、远方站、远程终端设备、移动设备、用户终端设备、终端设备、无线通信设备、用户代理、用户装置或UE(User Equipment，用户设备)。接入终端设备可以是蜂窝电话、无绳电话、SIP(Session Initiation Protocol，会话启动协议)电话、WLL(Wireless Local Loop，无线本地环路)站、PDA(Personal Digital Assistant，个人数字处理)、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。此外，结合基站描述了各个实施例。基站可用于与移动设备通信，基站可以是GSM(Global System of Mobile communication，全球移动通讯)或CDMA(Code Division Multiple Access，码分多址)中的BTS(Base Transceiver Station，基站)，也可以是WCDMA(Wideband Code Division Multiple Access，宽带码分多址)中的NB(NodeB，基站)，还可以是LTE(Long Term Evolution，长期演进)中的eNB或eNodeB(Evolutional Node B，演进型基站)，或者中继站或接入点，或者未来5G网络中的基站设备等。
本专利所有实施例中的网络实体名称可以扩展为具有相同或类似功能的名称。
此外，本专利申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语"制品"涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，CD(Compact Disk，压缩盘)、DVD(Digital Versatile Disk，数字通用盘)等)，智能卡和闪存器件(例如，EPROM(Erasable Programmable Read-Only Memory，可擦写可编程只读存储器)、卡、棒或钥匙驱动器 等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语"机器可读介质"可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或所述数据的各种其它介质。
现在，参照图1，示出根据本文所述的各个实施例的无线通信***100。无线通信***100包括基站102，基站102可包括多个天线组。每个天线组可以包括一个或多个天线，例如，一个天线组可包括天线104和106，另一个天线组可包括天线108和110，附加组可包括天线112和114。图1中对于每个天线组示出了2个天线，然而可对于每个组使用更多或更少的天线。基站102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)。
基站102可以与一个或多个接入终端设备(例如接入终端设备116和接入终端设备122)通信。然而，可以理解，基站102可以与类似于接入终端设备116或122的任意数目的接入终端设备通信。接入终端设备116和122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***、PDA和/或用于在无线通信***100上通信的任意其它适合设备。如图所示，接入终端设备116与天线112和114通信，其中天线112和114通过前向链路118向接入终端设备116发送信息，并通过反向链路120从接入终端设备116接收信息。此外，接入终端设备122与天线104和106通信，其中天线104和106通过前向链路124向接入终端设备122发送信息，并通过反向链路126从接入终端设备122接收信息。在FDD(Frequency Division Duplex，频分双工)***中，例如，前向链路118可利用与反向链路120所使用的不同频带，前向链路124可利用与反向链路126所使用的不同频带。此外，在TDD(Time Division Duplex，时分双工)***中，前向链路118和反向链路120可使用共同频带，前向链路124和反向链路126可使用共同频带。
被设计用于通信的每组天线和/或区域称为基站102的扇区。例如，可将天线组设计为与基站102覆盖区域的扇区中的接入终端设备通信。在基站102通过前向链路118和124分别与接入终端设备116和122进行通信的过程中，基站102的发射天线可利用波束成形来改善前向链路118和124的信噪比。此外，与基站通过单个天线向它所有的接入终端设备发送信号的方式相比，在基站102利用波束成形向相关覆盖区域中随机分散的接入终端设备116和122发送信号时，相邻小区中的移动设备会受到较少 的干扰。
在给定时间，基站102、接入终端设备116或接入终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送所述数据时，无线通信发送装置可对所述数据进行编码以用于传输。具体地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的所述数据比特。这种所述数据比特可包含在所述数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
传统无线网络使用固定发送时间间隔(TTI)长度。例如，在第三代合作伙伴计划(3GPP)长期演进(LTE)版本8(release 8)电信标准下操作的网络使用的传输时间间隔(TTI)为1毫秒(ms)。TTI的长度可以显著影响网络的时延性能和吞吐量性能。具体而言，较短的TTI通过提供更为频繁的发送机会实现优越的时延性能，而较长的TTI通过降低信令开销实现优越的吞吐量性能。
为满足未来***需要支持极短传输时延业务的需求，在空口会采用更短的传输时间间隔(TTI)设计。例如,进一步缩短TTI至0.5ms、0.25ms甚至更短。但使用较短的TTI传输对传输数据量较大的业务由于需要多次调度传输及反馈，会带来额外的控制信息传输开销，增加传输成本。
本专利申请提出了一个无线通信***，将***频带分成多个子带，每个子带分别配置不同时长的TTI。图2示出了将一个频带分成2个子带的场景。***频带具体包括第一子带201和第二子带203。第一子带201和第二子带203之间可以有保护带宽(Guard Band,GB)。保护带宽>＝0Hz。第一子带201具有第一传输时间间隔TTI_1。第二子带203具有第二传输时间间隔TTI_2。第二传输时间间隔TTI_2大于第一传输时间间隔TTI_1。即，TTI_1时长较短，TTI_2时长较长。TTI_2可以是TTI_1的整数倍，即TTI_2＝N×TTI_1。其中N为正整数。在图2中，以TTI_2＝2×TTI_1为例进行说明。本专利申请中并不限定第二传输时间间隔TTI_2一定要是第一传输时间间隔TTI_1的整数倍。在TTI_2是TTI_1的整数倍时，如果在第一传输时间间隔TTI_1和第二传输时间间隔TTI_2内发送和接收信息，调度处理会更简单。
第一子带201中的每个第一传输时间间隔TTI_1都对应有第一控制信道和第一数据信道的传输时间。第二子带203中的每个第二传输时间间隔TTI_2都对应有第二控制信道和第二数据信道的传输时间。第一控制信道和第二控制信道可以传输终端设备 的控制信息。第一数据信道和第二数据信道可以传输终端设备的数据。在第一子带201和第二子带203中，有些TTI内还包含公共控制信道，如广播信道，同步信道，随机接入信道等，分别用于传输小区***信息，终端设备接入等。本专利申请不涉及公共控制信道，因此没有在图中示出。
需要注意的是，本专利申请中的无线通信***本身不限于只划分为2个子带，配置2类不同时长的TTI的情况。无线通信***本身可以划分为多个子带，比如可以划分为3个、4个及更多的子带。各个子带的TTI不同。
上面以一个子带内的TTI时长是固定的为例进行说明。本领域技术人员应当清楚一个子带在不同TTI时长也是可以变化的。
对于一个终端设备，其短时延、大数据量业务可以混合使用第一子带201中的TTI_1和第二子带203中的TTI_2。终端设备在第一子带201上传输终端设备的控制信息，在第二子带203上传输终端设备的数据。
下面将分上行和下行两种情况，对本专利申请的通信传输方法做进一步详细说明。
图3示出了本专利申请一个实施例的一种通信传输方法。该通信传输方法所应用的无线通信***包括上行第一子带和第二子带，下行第一子带和第二子带。其中上行和下行第一子带具有第一传输时间间隔TTI_1。上行和下行第二子带具有第二传输时间间隔TTI_2。第二传输时间间隔TTI_2大于第一传输时间间隔TTI_1。基站和终端设备支持在上行和下行第一子带和第二子带中发送和接收信息。
该通信方法包括如下步骤：
301、终端设备通过空中接口在上行第一子带采用TTI_1向基站发送调度请求信息。基站在上行第一子带采用TTI_1接收终端设备发送的调度请求信息。调度请求消息包括调度请求(scheduling request,SR)或缓存状态报告(buffer status report,BSR)。调度请求和缓存状态报告都会触发上行数据的调度传输，本专利申请中不予区分，统一以调度请求描述。
303、基站接收调度请求信息后，开始进行309、调度处理。调度处理可以根据确定的传输模式来进行。关于调度处理，下面将做进一步详细说明。调度处理后为终端设备在相应的上行第二子带内分配传输所需的时频资源。基站在下行第一子带采用TTI_1向终端设备发送调度授予信息。终端设备在下行第一子带采用TTI_1接收基站发送的调度授予信息。
305、终端设备接收调度授予信息后，对数据进行基带处理，例如：编码和调制等。在基站所分配的上行第二子带的时频资源上采用TTI_2向基站发送数据。基站在上行第二子带采用TTI_2上接收终端设备发送的数据。
基站在上行第二子带TTI_2上接收终端设备发送的数据后，对数据进行基带处理，例如：解调和译码等。基站在下行第一子带采用TTI_1向终端设备发送传输反馈信息。终端设备在下行第一子带采用TTI_1接收基站发送的传输反馈信息。在译码不成功的情况下，则具体进行步骤307A，在步骤307A中，反馈信息是否定应答(Negative Acknowledgement，NACK)消息。基站在下行第一子带采用TTI_1向终端设备发送NACK消息。在译码成功的情况下，则具体进行步骤307B，在步骤307B中，反馈消息是应答(Acknowledgement，ACK)消息。基站在下行第一子带采用TTI_1向终端设备发送ACK消息。这表示数据传输成功，结束一次传输。
在发生步骤307A的情况下，该通信方法还包括如下步骤：
308、终端设备接收NACK消息后，如果采用上行同步非自适应重传，则终端设备在上行第二子带采用TTI_2和第一次所分配的时频资源相同的时频资源上对终端设备数据进行重传。基站在上行第二子带的该时频资源上接收终端设备发送的数据。如果采用上行同步自适应重传，则重新进行309、调度处理，基站调度处理后为终端设备在相应的上行第二子带内分配重传所需的时频资源。然后可以继续进行调度授予、用户数据传输传输反馈，具体可以再进行步骤303、305和307A或进行步骤303、305和307B。
如图4所示，该通信方法中的传输模式还可通过如下步骤确定：
401、终端设备向基站提供终端设备的业务需求。基站获取终端设备的业务需求。具体地，基站可以在终端设备接入时，根据终端设备的签约信息获取。或者在终端设备请求业务时，根据存储在网络侧的控制器，如LTE***中的移动性管理实体(mobility management entity，MME)的指示业务需求的终端设备上下文信息获取。或者在终端设备请求业务时，根据上报的业务类型或切片类型获取。
403、基站根据业务需求进行传输模式决策。
根据无线通信***所支持的第一传输时间间隔TTI_1和第二传输时间间隔TTI_2，同时根据业务需求，终端设备数据和终端设备控制信息的传输可以包括三种模式：
第一种、终端设备数据和终端设备控制信息均采用采用第二传输时间间隔TTI_2 传输，这适合时延不敏感业务，例如：时延不敏感的邮件、FTP等下载业务。
第二种、终端设备数据和终端设备控制信息均采用采用第一传输时间间隔TTI_1传输，这适合时延敏感同时数据量小的业务，例如工业控制、传感器报警。
第三种、终端设备数据采用第二传输时间间隔TTI_2传输，而终端设备控制信息采用第一传输时间间隔TTI_1传输，这适合时延敏感同时数据量较大的业务，例如：远程医疗等业务。本专利申请中，重点关注第三种。
405、基站向终端设备发送传输模式配置信息。终端设备接收基站发送的传输模式配置信息。传输模式配置信息可以在无线资源控制(radio resource control，RRC)连接重配置(connection reconfiguration)信令中增加传输模式字段(trans.Mode)，以2比特指示，具体如下表所示：
Figure PCTCN2016109276-appb-000001
在第三种传输模式的情况下，传输模式配置信息指示终端设备采用第一传输时间间隔TTI_1传输终端设备的控制信息并且采用第二传输时间间隔TTI_2传输终端设备的数据。
由于用户数据采用TTI_2传输，即一次调度分配的时频资源时长为TTI_2，而用户控制信息采用TTI_1传输，如果调度器的调度起始时间和TTI_1起始位置对齐，则会出现对时频资源的调度冲突。具体的，如图5所示，如果在TTI_1起始时间开始调度，则对于在第(m)TTI_1到达的调度请求，从第(m+1)TTI_1开始时进行调度，对于在第(m+1)TTI_1内到达的调度请求，在第(m+2)TTI_1开始时进行调度。假设调度时间为TTI_2，由于调度的是相同的时频资源，可能发生在(m+1)TTI_1内收到的调度请求的业务优先级高，但由于调度的晚而无法获得所需的时频资源进行传输的问题，使得用户业务的业务质量(Quality of service，QoS)得不到满足。
基站也可以不需要获取业务需求，而直接进行传输模式配置。
本专利申请中提出了一种解决方案。在这种解决方案中，调度处理的开始时间始 终与第二传输时间间隔TTI_2起始时间对齐。对于一个TTI_2时长内对应的多个TTI_1时长内的调度请求。如图6所示，调度器在收到第m个TTI_1内的SR调度请求后等待，直到收到第m+1个TTI_1内的SR调度请求后再集中进行调度.针对第m和第m+1个TTI_1内的调度请求的SG调度授予统一在第m+4这个TTI_1内下发，即在第m，m+1发送SR的UE在m+4接收SG。此时提前到达的调度请求需要等待n(n<k)个TTI_1时长再进行调度，即使用TTI_2时长的调度周期。针对一个TTI_2中包含k个TTI_1的场景，第一个TTI_1内收到的SR调度请求需要等待k-1个TTI_1时长再进行调度，第二个TTI_1内收到的SR调度请求需要等待k-2个TTI_1时长再进行调度，以此类推，直到收到第k-1个TTI_1内的SR调度请求。虽然提前到达的调度请求在调度前需要额外的等待，但由于时频资源统一调度，可以获得有效的时频资源利用率，同时满足用户不同的业务需求。
本专利申请中还提出了另一种解决方案。在这种解决方案中，调度开始时间可以与第一传输时间间隔TTI_1起始时间对齐。此时需要将第二传输时间间隔TTI_2时长内的时频资源进行协同，分别分配给在各TTI_1接收到的调度请求。如图7所示，可以将TTI_2时长内的时频资源分成两部分，一部分分配给在第m个TTI_1到达的调度请求，另一部分分配给在第m+1个TTI_1到达的调度请求。此时在m+1发送SR的UE在m+3接收SG，在m+2发送SR的UE在m+4接收SG，即针对一个TTI_1时长内的调度请求，调度授予反馈时间在一个固定延时，例如调度处理时间后的一个TTI_1内。本方案可以对调度请求进行及时调度，同时调度授予信息在不同的TTI_1中发送，可以空出TTI_1中的时频资源用于传输其它终端设备的时延敏感业务的控制信息和数据，满足不同用户的业务需求。
本实施例以频分复用(Frequency Division Duplex，FDD)为例进行说明，对时分复用(Time Division Duplex，TDD)***同样适用。
上面以上行终端设备数据的传输为例进行了说明，下面再以下行终端设备数据的传输为例对本专利申请做进一步描述。
图8示出了根据本专利申请另一个实施例的一种通信传输方法。该通信方法包括如下步骤：
801、当下行终端设备数据到达基站时，根据确定的传输模式，基站调度器开始进行调度，为终端设备在相应的下行第二子带内分配下行终端设备数据传输所需的时频 资源。基站在下行第一子带采用第一传输时间间隔TTI_1向终端设备发送调度授予信息。终端设备在下行第一子带采用第一传输时间间隔TTI_1接收基站发送的调度授予信息。基站在下行第二子带采用第二传输时间间隔TTI_2向终端设备发送数据。
终端设备接收调度授予信息后，根据调度授予信息在下行第二子带采用第二传输时间间隔TTI_2接收基站发送的数据。终端设备将数据进行基带处理，例如解调、译码等。终端设备在上行第一子带采用第一传输时间间隔TTI_1向基站发送传输反馈信息。基站在上行第一子带采用第一传输时间间隔TTI_1接收终端设备发送的传输反馈信息。
在译码不成功的情况下，则具体进行步骤802A，在步骤802A中，反馈信息是否定应答(Negative Acknowledgement，NACK)消息。终端设备在上行第一子带采用第一传输时间间隔TTI_1向基站发送NACK消息。这表示这次数据传输失败，将会触发数据重传。在译码成功的情况下，则具体进行步骤802B，在步骤802B中，反馈消息是应答(Acknowledgement，ACK)消息。终端设备在上行第一子带采用第一传输时间间隔TTI_1向基站发送ACK消息。这表示数据传输成功，结束一次传输。
在发生步骤802A的情况下，该通信方法还包括如下步骤：
803、基站接收NACK消息后，进行数据重传。如果采用下行异步自适应重传，则基站重新进入步骤801。基站选择再次调度该终端，为终端在相应的下行第二子带内分配下行终端数据重传所需的时频资源，调度授予信息在下行第一子带采用第一传输时间间隔TTI_1发送给终端，同时将重传数据在下行第二子带采用第二传输时间间隔TTI_2内发送给终端，然后等待接收下行终端数据重传反馈。终端设备接收调度授予信息后，根据调度授予信息在下行第二子带采用第二传输时间间隔TTI_2内接收基站发送的数据。终端设备将数据进行基带处理，例如解调、译码等。终端设备在上行第一子带采用第一传输时间间隔TTI_1向基站发送传输反馈信息。基站在上行第一子带采用第一传输时间间隔TTI_1接收终端设备发送的传输反馈信息。在译码不成功的情况下，则具体进行步骤802A，在译码成功的情况下，则具体进行步骤802B。
上面以一次重传为例进行描述，但本专利申请不限于一次重传场景，可以是没有重传，即一次传输成功的场景。或者本专利申请重传次数不大于最大重传次次数。
下行数据传输中，传输模式也可以通过图4所示实施例获取。基站进行调度的处理也可以参考上文关于图5和图6所示的方式进行处理。具体地，调度处理的开始时 间始终与第二传输时间间隔TTI_2起始时间对齐。对于一个TTI_2时长内对应的多个TTI_1时长内收到的下行数据，如图9所示，调度器在收到第m个TTI_1内的下行数据后等待，直到收到第(m+1)个TTI_1内的下行数据后再集中进行调度。针对第m和第(m+1)个TTI_1内的下行数据传输的SG调度授予统一在第(m+4)这个TTI_1内下发，即在第m，m+1有下行数据传输的UE在m+4接收SG。此时提前到达的下行数据需要等待n(n<k)个TTI_1时长再进行调度，即使用TTI_2时长的调度周期。针对一个TTI_2中包含k个TTI_1的场景，第一个TTI_1内收到下行数据需要等待k-1个TTI_1时长再进行调度，第二个TTI_1内收到的下行数据需要等待k-2个TTI_1时长再进行调度，以此类推，直到收到第k-1个TTI_1内的下行数据。虽然提前到达的下行数据在调度前需要额外的等待，但由于时频资源统一调度，可以获得有效的时频资源利用率，同时满足用户不同的业务需求。
本专利申请中还提出了另一种解决方案。在这种解决方案中，调度开始时间可以与第一传输时间间隔TTI_1起始时间对齐。此时需要将第二传输时间间隔TTI_2时长内的时频资源进行协同，分别分配给在各TTI_1接收到的下行数据调度请求。如图10所示，可以将TTI_2时长内的时频资源分成几部分，一部分分配给在第m个TTI_1到达的下行数据调度请求，另一部分分配给在第m+1个TTI_1到达的下行数据调度请求。此时在m+1到达的下行数据调度请求在m+3发送调度授予信息至UE，在m+2到达的下行数据调度请求在m+4发送调度授予至UE，即针对一个TTI_1时长内的下行数据调度请求，调度授予反馈时间在一个固定延时，例如调度处理时间后的一个TTI_1内。此时在m+3发送的调度授予信息中还需要指示为UE分配的时频资源是在下一个TTI_2内。本方案可以对下行数据调度请求进行及时调度，同时调度授予信息在不同的TTI_1中发送，可以空出TTI_1中的时频资源用于传输其它终端设备的时延敏感业务的控制信息和数据，满足不同用户的业务需求。
