本申请实施例涉及领域通领域，并且更具体地，涉及一种发送反馈信息的方法及其装置和接收反馈信息的方法及其装置。
背景技术
移动通信技术已经深刻地改变了人们的生活，但人们对更高性能的移动通信技术的追求从未停止。为了应对未来爆炸性的移动数据流量增长、海量移动通信的设备连接、不断涌现的各类新业务和应用场景，第五代(the fifth generation，5G)移动通信系统应运而生。5G移动通信系统需要支持增强型移动宽带(enhanced mobile broadband，eMBB)业务、高可靠低时延通信(ultra reliable and low latency communications，URLLC)业务以及海量机器类通信(massive machine type communications，mMTC)业务。
典型的URLLC业务有：工业制造或生产流程中的无线控制、无人驾驶汽车和无人驾驶飞机的运动控制以及远程手术等触觉交互类应用，这些业务的主要特点是超高可靠性、低延时，传输数据量较少以及具有突发性。
URLLC业务对时延要求极高，不考虑可靠性的情况下，传输时延要求在0.5毫秒(millisecond，ms)以内；在达到99.999％的可靠性的前提下，传输时延要求在1ms以内。
因此，亟需一种发送反馈信息和接收反馈信息的方法，能够满足业务对高可靠性的要求。

作为示例，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。

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使用的传输资源(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和发射功率低的特点，适用于提供高速率的数据传输服务。
本申请实施例提供的方法和装置，可以应用于终端设备或网络设备，该终端设备或网络设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、以及即时通信软件等应用。并且，在本申请实施例中，传输信号的方法的执行主体的具体结构，本申请实施例并未特别限定，只要能够通过运行记录有本申请实施例的传输信号的方法的代码的程序，以根据本申请实施例的传输信号的方法 进行通信即可，例如，本申请实施例的无线通信的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。

在当前的讨论中，一个共识是mini-slot的概念可以应用在高频系统中大带宽调度的场景下，即调度策略倾向于较小的时间颗粒度。但是，对于如何基于mini-slot进行数据调度还没有确定的方案。此外，如何基于mini-slot监听下行控制信道也没有确定的方案。
针对上述问题，本申请实施例提出了一种数据发送方法和一种数据接收方法以及相应的网络设备和终端设备。
图1是应用于本申请实施例无线通信系统的示意图。如图1所示，该无线通信系统100包括网络设备102，网络设备102可包括1个天线或多个天线例如，天线104、106、108、110、112和114。另外，网络设备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)。
网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而，可以理解，网络设备102可以与类似于终端设备116或终端设备122的任意数目的终端设备通信。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。
如图1所示，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(也称为下行链路)118向终端设备116发送信息，并通过反向链路(也称为上行链路)120从终端设备116接收信息。此外，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向终端设备122发送信息，并通过反向链路126从终端设备122接收信息。
例如，在频分双工(frequency division duplex，FDD)系统中，例如，前向链路118可与反向链路120使用不同的频带，前向链路124可与反向链路126使用不同的频带。
再例如，在时分双工(time division duplex，TDD)系统、全双工(full duplex)系统和灵活双工系统中，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个天线(或者由多个天线组成的天线组)和/或区域称为网络设备102的扇区。例如，可将天线组设计为与网络设备102覆盖区域的扇区中的终端设备通信。网络设备可以通过单个天线或多天线发射分集向其对应的扇区内所有的终端设备发送信号。在网络设备102通过前向链路118和124分别与终端设备116和122进行通信的过 程中，网络设备102的发射天线也可利用波束成形来改善前向链路118和124的信噪比。此外，与网络设备通过单个天线或多天线发射分集向它所有的终端设备发送信号的方式相比，在网络设备102利用波束成形向相关覆盖区域中随机分散的终端设备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，网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对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数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
此外，该通信系统100可以是PLMN网络或者D2D网络或者M2M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。

可选的，网络设备还可以包括总线205。其中，接收器202、发送器203、以及存储器204可以通过总线205与处理器201连接；总线205可以是外设部件互连标准(Peripheral Component Interconnect，PCI)总线或扩展工业标准结构(Extended Industry Standard Architecture，EISA)总线等。所述总线205可以分为地址总线、数据总线、控制总线等。为便于表示，图7中仅用一条粗线表示，但并不表示仅有一根总线或一种类型的总线。
处理器201例如可以是中央处理器(Central Processing Unit，CPU)，通用处理器，数字信号处理器(Digital Signal Processor，DSP)，专用集成电路(Application-Specific Integrated Circuit，ASIC)，现场可编程门阵列(Field Programmable Gate Array，FPGA)或者其他可编程逻辑器件、晶体管逻辑器件、硬件部件或者其任意组合。其可以实现或执行结合本申请公开内容所描述的各种示例性的逻辑方框，模块和电路。所述处理器也可以是实现计算功能的组合，例如包含一个或多个微处理器组合，DSP和微处理器的组合等等。
接收器202和发送器203可以是包括上述天线和发射机链和接收机链的电路，二者可以是独立的电路，也可以是同一个电路。
图3为上述无线通信系统中，终端设备的结构示意图。该终端设备该网络设备能够执行本申请实施例提供的数据接收方法。该终端设备可以包括处理器301、接收器302、发送器303、以及存储器304。可选的，该处理器301可以与接收器302和发送器303通信连接。或者，该终端设备还可以包括总线305，该接收器302、发送器303、以及存储器304可以通过总线305与处理器301连接。总线305可以是外设部件互连标准(Peripheral Component Interconnect，PCI)总线或扩展工业标准结构(Extended Industry Standard Architecture，EISA)总线等。所述总线305可以分为地址总线、数据总线、控制总线等。为便于表示，图3中仅用一条粗线表示，但并不表示仅有一根总线或一种类型的总线。
相应的，该存储器304可以用于存储该终端设备的程序代码和数据。因此，该存储器 304可以是处理器301内部的存储单元，也可以是与处理器301独立的外部存储单元，还可以是包括处理器301内部的存储单元和与处理器201独立的外部存储单元的部件。接收器302和发送器303可以是独立的电路，也可以是同一个电路。
为了提高URLLC业务的可靠性，一种常见的方法是将一个信息块重复发送N次，同时为了提高控制信道的可靠性，可以发送多个下行控制信息，该多个下行控制信息调度同一信息块的N次传输，其中，N为大于1的整数。举例来说，图4示出了本申请一个实施例的应用场景的示意图，如图4所示，分别发送3个下行控制信息，调度同一个信息块的3次传输。应理解，图4仅仅是示例性的应用场景图，本申请实施例不限于此。
然而，在实际传输过程中，可能会存在某一个或多个下行控制信息发送失败的情况，举例来说，如果URLLC业务可靠性需求为99.999％，也就是误块率最大为10 -5，那么基站可能通过调度3次传输，每次的误块率为10 -2来满足可靠性需求，如果第一个下行控制信息丢失，则丢失一次传输，使得数据可靠性只能达到1-(10 -2) 2＝99.99％，无法达到99.999％，一旦所有的下行控制信息均未接收到，终端设备错失至少三次调度机会，从而传输失败。
因此，在发送多个下行控制信息调度同一个信息块的多次传输时，如何进一步提高URLLC业务的传输可靠性成为需要解决的问题。
在本申请实施例中，时间单元可以包括一个或多个时域符号，也可以包括一个或多个时隙(slot)，还可以包括一个或多个迷你时隙(mini-slot)，或者，包括一个或多个子帧(subframe)。上述时间单元包括多个时间单元时，该多个时间单元可以是连续的，也可是不连续的，本申请不做限定。其中，上述时域符号可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，也可以是单载波频分复用(single-carrier frequency-division multiplexing，SC-FDM)符号。
在本申请实施例中，信息块可以为传输块(transport block，TB)、编码块(code block，CB)、编码块组(code block group，CBG)，其中，CB包含一组信息比特，该组信息比特一起用于一次信道编码，或者说，该组信息比特被发送设备一起进行信道编码，对应一个信道编码后的比特块；CBG至少包括一个编码块，可以包括多个编码块；TB包括至少一个CB，也可以包括至少一个CBG，本申请不做限定。
下面具体描述本申请实施例的方法。图5所示为本申请实施例的方法中数据传输交互图。如图5所示，该方法包括如下步骤。需要说明的是，图5中的虚线表示相应的步骤为可选步骤。
步骤501，网络设备在第一时间单元上向终端设备发送第一参考信号，其中，该第一参考信号对应于第一下行控制信息，第一下行控制信息用于调度第一信息块。相应地，终端设备在第一时间单元上接收网络设备发送的第一参考信息。
具体地，第一信息块可以为长期演进(Long Term Evolution，LTE)系统中的传输块(transmission block，TB)，第一下行控制信息用于调度该第一信息块，网络设备使用第一时间单元向终端设备发送该第一信息块，其中，第一下行控制信息可以为LTE系统中下行控制信息(downlink control information，DCI)。
其中，第一下行控制信息可以承载在第一下行控制信道中，其中，第一控制信道可以为下行控制信道(physical downlink control channel，PDCCH)或其它用于承载物理层控制 信息的下行信道，本申请不做限定。
进一步地，上述第一下行控制信道中还承载了第一参考信号，具体地，该第一参考信号可以为LTE系统中的(reference signals，RS)，具体地，第一参考信号对应于第一下行控制信息指的是：终端设备能够根据该第一参考信号进行第一下行控制信息的解调和译码。
步骤502，终端设备根据第一参考信号确定第一时间单元上的第一下行控制信息接收失败。
具体地，如果终端设备接收到网络设备发送的第一参考信号，那么能够确定网络设备在第一时间单元上发送该第一下行控制信息，但终端设备如果没有收到该第一下行控制信息，或者对该第一下行控制信息进行解调和译码失败，那么该终端设备确定第一下行控制信息接收失败。
步骤503，终端设备在第一时间单元对应的第一资源上向网络设备发送第一反馈信息，其中，第一反馈信息表示第一下行控制信息接收失败。
具体地，第一时间单元对应的第一资源指的是：第一资源与第一时间单元具有确定的时频资源关系。也就是说，每个时间单元对应一个用于发送上行反馈信息的第一资源。
具体地，第一反馈信息可以为表征第一下行控制信息接收失败的反馈信息，在本申请实施例中，为了便于描述，下行控制信息接收失败的反馈信息可以简写为PDCCH接收失败，本申请不做限定。
因此，本申请实施例提供的方法通过向网络设备发送下行控制信息接收失败的反馈信息，有以利于网络设备根据该反馈信息，调整下一次向终端设备发送的下行控制信息的发送功率或者聚合等级等，从而有以利于提升业务传输的可靠性。
除此之外，终端设备根据网络设备发送的第一参考信号，确定网络设备发送了下行控制信息，在多次收到第一参考信号，但又没收到网络设备发送的下行控制信息时，终端设备可以将可能承载下行控制信息的候选下行控制信道进行合并，从而提升业务传输的可靠性。
可选地，作为本申请一个实施例，所述第一资源用于发送至少两个信息比特，所述至少两个信息比特的第一状态用于指示所述第一反馈信息；所述至少两个信息比特的第二状态用于指示第二反馈信息，其中，所述第二反馈信息用于指示传输参数调整值，所述传输参数调整值是所述终端设备根据所述第一时间单元上接收到的第二参考信号确定的；所述至少两个信息比特的第三状态用于指示第三反馈信息，所述第三反馈信息用于表示所述终端设备正确译码在时间单元m-s上接收的所述第一信息块，所述第一时间单元为时间单元m，所述m和s为正整数，且m大于或等于s；所述终端设备发送第一反馈信息，包括：所述终端设备在所述第一资源上发送所述第一状态。
也就是说，第一时间单元对应的第一资源可以用于发送至少两个信息比特，该两个信息比特的不同状态可以用于指示上述三种反馈信息：第一反馈信息、第二反馈信息、第三反馈信息。
具体地，上述传输参数包括下列中至少一项：调制方式、编码方式、发送功率和波束设置中的至少一项。
应理解，第一参考信号是用于第一时间单元上的控制信道解调的参考信号，第二参考 信号是用于第一时间单元上的数据信道数据解调的参考信号，当数据信道和控制信道的参考信号可以共享时，第一参考信号和第二参考信号相同。
具体地，第三反馈信息用于表示终端设备正确译码在时间单元m-s上接收的第一信息块，也就是说，第三反馈信息可以为第一传输的确认(acknowledgement)消息。
可选地，作为本申请一个实施例，所述方法还包括：所述终端设备在第二时间单元对应的第一资源发送所述第三状态，其中，所述第二时间单元为时间单元n，所述第三状态指示所述终端设备正确译码在时间单元n-k上接收的所述第一信息块，所述n和k为正整数，且n大于或等于k；或者，当所述终端设备在第二时间单元上成功译码第二下行控制信息时，所述终端设备在所述第二时间单元对应的第一资源发送所述第二状态，其中，所述第二下行控制信息用于调度所述第一信息块，所述第二状态用于指示传输参数调整值，所述传输参数调整值是所述终端设备根据所述第二时间单元上接收到的第三参考信号确定的，并且，所述第n-k时间单元上接收的所述第一信息块接收失败，所述第二时间单元为时间单元n，所述n和k为正整数，且n大于或等于k。
也就是说，在一种情况下，如果某个时间单元(例如，时间单元n)对应的进行上行信息反馈的资源只有一个，即第一资源，如果终端设备在时间单元n-k上接收的第一信息块正确译码，那么则在该第一资源上发送第三反馈信息，也就是反馈第一信息块正确译码的反馈信息。
也就是说，在另外一种情况下，如果某个时间单元(例如，时间单元n)对应的进行上行信息反馈的资源只有一个，即第一资源，如果在第n个时间单元，终端设备不需要反馈第三反馈信息时，也就是说第n个时间单元前没有接收到第一信息块，或者第一信息块解码失败，或者第一信息块解调译码未结束，或者第一信息块解调译码成功但是未生成第三反馈信息时，并且，终端设备在时间单元n上成功译码第二下行控制信息时，那么则在该第一资源上发送第二反馈信息，该第二反馈信息包括传输参数调整值。
也就是说，在另外一种情况下，如果某个时间单元(例如，时间单元n)对应的进行上行信息反馈的资源只有一个，即第一资源，如果在第n个时间单元，终端设备不需要反馈第三反馈信息时，也就是说第n个时间单元前没有接收到第一信息块，或者第一信息块解码失败，或者第一信息块解调译码未结束，或者第一信息块解调译码成功但是未生成第三反馈信息时，并且，终端设备接收到网络设备发送的第一参考信号，但又没有接收到网络设备发送的下行控制信息，那么则在该第一资源上发送第一反馈信息。
下面结合图6进行描述，图6示出了本申请一个实施例的示意图。其中，第一反馈信息用于反馈第m个时间单元上的下行控制信息接收失败；第二反馈信息用于反馈传输参数调整值，例如，该第二反馈信息可以用于反馈调制编码方案(modulation and coding scheme，MCS)调整值，可以简写为Delta_MCS；第三反馈信息用于反馈第m-3个时间单元上发送的第一信息块的ACK。那么上述三个反馈信息可以使用第m个时间单元对应的第一资源进行上述三种反馈信息中的任意一种信息的反馈。
应理解，图6中示出用于传输第一信息块的三个时间单元仅仅是示例性的，实际通信过程中可能存在更多的时间单元，或者，实际通信过程在不存在第m-3、m-2或m-1中的至少一个时间单元，本申请不做限定。
假设上述第一资源用于发送3个信息比特，那么该三个信息比特的不同状态可以表征 不同的反馈信息，如表1所示。
表1
Figure PCTCN2018082865-appb-000001
表1中最后一列示出的三个信息比特的6种状态分别表示了PDCCH接收失败、Delt_MCS1、Delt_MCS2、Delt_MCS3、Delt_MCS4以及ACK。
具体地，如果终端设备接收到第一参考信号，确认基站发送了PDCCH，但是用户未接收到自己的PDCCH，并且终端设备此时没有接收到所述第一信息块或者接收到的第一信息块解调译码失败时，终端设备反馈PDCCH接收失败消息给网络设备，例如，如表1所示，终端设备反馈“000”给网络设备。此时，网络设备接收到“000”，网络设备则能够确定该反馈信息为第一反馈信息，以便于网络设备根据该第一反馈信息在第三时间单元上发送第二下行控制信息，该第二下行控制信息用于调度第一信息块，如果第一时间单元为m，那么第三时间单元为m+p，其中p为正整数。

应理解，表1和表2仅仅是示例性的，根据传输参数不同可以灵活选择2个或2个以上的信息比特表征不同的反馈信息。例如，当传输参数有M个值时，那么可以至少使用[log 2(M+2)]个信息比特的不同状态表示上述三种反馈信息，其中，M为正整数。并且，每个信息比特状态与所述第一反馈信息，第二反馈信息，第三反馈信息的对应关系仅是示例性的。例如，也可以用“11”表示PDCCH接收失败，用“00”表示ACK，本申请不做限定。
可选地，作为本申请一个实施例，网络设备接收所述第一反馈信息时，所述方法还包括：步骤504，网络设备使用第二聚合等级发送第二下行控制信息，所述第二聚合等级高于第一聚合等级，所述网络设备使用第一聚合等级发送所述第一下行控制信息，所述第二消息控制信息用于调度所述第一信息块，和/或网络设备使用第二发送功率发送第二下行控制信息，所述第二发送功率比第一发送功率高，所述网络设备采用所述第一发送功率发送第一控制信息，所述第二控制信息用于调度所述第一信息块。
也就是说，网络设备根据终端设备返回的第一反馈信息，能够使用更高的聚合等级和/或更高的发送功率发送调度第一信息块下一次传输的下行控制信息，能够有利于提升业务传输的可靠性。
因此，对于每个时间单元来说，本申请实施例提供了一种资源复用的方法，多个反馈信息对应于一个第一资源进行发送，资源的开销较小。

也就是说，第一时间单元对应的第一资源用于发送第一反馈信息，而第一时间单元对 应的第二资源用于发送第二反馈信息或第三反馈信息。
也就是说，在一种情况下，如果某个时间单元(例如，时间单元n)对应的进行上行信息反馈的资源有两个，即第一资源和第二资源，如果终端设备在时间单元n-k上接收的第一信息块正确译码，那么则在第二资源上发送第三反馈信息，也就是反馈第一信息块正确译码的反馈信息。
也就是说，在另外一种情况下，如果某个时间单元(例如，时间单元n)对应的进行上行信息反馈的资源有两个，即第一资源和第二资源，如果在第n个时间单元，终端设备不需要反馈第三反馈信息时，也就是说第n个时间单元前没有接收到第一信息块，或者第一信息块解码失败，或者第一信息块解调译码未结束，或者第一信息块解调译码成功但是未生成第三反馈信息时，并且，终端设备在时间单元n上成功译码第二下行控制信息时，那么则在该第二资源上发送第二反馈信息，该第二反馈信息包括传输参数调整值。

其中，第一时间单元的第一资源可以为预设的资源，也可以是网络设备通过高层信令指示终端设备的，本申请不做限定；同理，第一时间单元的第二资源可以为预设的资源，也可以为网络设备通过高层信令指示终端设备，本申请不做限定。
