Description

一种传输信息的方法和装置
本申请要求于2019年3月18日提交中国专利局、申请号为201910204987.1、申请名称为“一种传输信息的方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，并且更具体地，涉及一种传输信息的方法和装置。
背景技术
在现有通信***中，终端设备接收下行数据，生成混合自动重传请求(hybrid automatic repeat request，HARQ)反馈信息，其中，HARQ反馈信息包括肯定应答消息(positive acknowledgement，ACK)和否定应答消息(negative acknowledgement，NACK)。肯定应答消息表示终端设备成功接收(correctly received)下行数据；否定应答消息表示终端设备没有成功接收(incorrectly received)下行数据。
由于终端设备频繁的发送HARQ反馈信息，可能导致不同的终端设备发送的HARQ反馈信息之间的干扰，从而导致网络设备无法正确接收到HARQ反馈信息。
网络设备可能将NACK错误的理解为ACK，进而网络设备不再对已经失败的传输块(TB，Transport block)进行重传，导致***的传输效率下降，恶化通信***的指标。
网络设备还有可能将ACK错误的理解为NACK，进而对无需重传的TB重新发送，导致重发的TB占用额外的***资源，阻塞其他数据的发送，也会使得***的数据传输效率下降。

具体实施方式
以下，对本申请中的部分用语进行说明：
1)、终端设备，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音/数据连通性的设备，例如，具有无线连接功能的手持式设备、或车载设备等。目前，一些终端的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、或智慧家庭(smart home)中的无线终端等。
2)、网络设备是无线网络中的设备，例如将终端接入到无线网络的无线接入网(radio access network，RAN)节点。目前，一些RAN节点的举例为：gNB、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等。在一种网络结构中，网络设备可以包括集中单元(centralized unit，CU)节点、或分布单元(distributed unit，DU)节点、或包括CU节点和DU节点的RAN设备。
3)、“多个”是指两个或两个以上，其它量词与之类似。“和/或”描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。此外，对于单数形式“a”，“an”和“the”出现的元素(element)，除非上下文另有明确规定，否则其不意味着“一个或仅一个”，而是意 味着“一个或多于一个”。例如，“a device”意味着对一个或多个这样的device。再者，至少一个(at least one of).......”意味着后续关联对象中的一个或任意组合，例如“A，B和C中的至少一个”包括A，B，C，AB，AC，BC，或ABC。
本申请实施例的技术方案可以应用于各种通信***，例如：全球移动通信(global system for mobile communications，GSM)***、码分多址(code division multiple access，CDMA)***、宽带码分多址(wideband code division multiple access，WCDMA)***、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)***、LTE频分双工(frequency division duplex，FDD)***、LTE时分双工(time division duplex，TDD)、通用移动通信***(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信***、第五代(5th generation，5G)***或新无线(new radio，NR)等。
在本申请实施例中，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***层，以及运行在操作***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***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***，例如，Linux操作***、Unix操作***、Android操作***、iOS操作***或windows操作***等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供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。
另外，本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，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、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/或数据的各种其它介质。
图1是本申请实施例提供技术方案的应用场景的示意图，如图1所示，终端设备130接入到无线网络，以通过无线网络获取外网(例如因特网)的服务，或者通过无线网络与其它终端设备通信。该无线网络包括RAN110和核心网(CN)120，其中RAN110用于将终端设备130接入到无线网络，CN120用于对终端设备进行管理并提供与外网通信的网关。
应理解，本申请提供的传输信息的方法可适用于无线通信***，例如，图1中所示的无线通信***100。处于无线通信***中的两个通信装置间具有无线通信连接，该两个通信装置中的一个通信装置可对应于图1中所示的终端设备130，例如，可以为图1中的终端设备130，也可以为配置于终端设备130中的芯片；该两个通信装置中的另一个通信装置可对应于图1中所示的RAN110，例如，可以为图1中的RAN110，也可以为配置于 RAN110中的芯片。
图2是本申请实施例提供的一种网络架构的示意图，如图2所示，该网络架构包括CN设备和RAN设备。其中RAN设备包括基带装置和射频装置，其中基带装置可以由一个节点实现，也可以由多个节点实现，射频装置可以从基带装置拉远独立实现，也可以集成基带装置中，或者部分拉远部分集成在基带装置中。例如，在长期演进(Long Term Evolution，LTE)通信***中，RAN设备(eNB)包括基带装置和射频装置，其中射频装置可以相对于基带装置拉远布置，例如射频拉远单元(remote radio unit，RRU)相对于BBU拉远布置。
RAN设备和终端设备之间的通信遵循一定的协议层结构。例如控制面协议层结构可以包括无线资源控制(radio resource control，RRC)层、分组数据汇聚层协议(packet data convergence protocol，PDCP)层、无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理层等协议层的功能。用户面协议层结构可以包括PDCP层、RLC层、MAC层和物理层等协议层的功能；在一种实现中，PDCP层之上还可以包括业务数据适配(service data adaptation protocol,SDAP)层。
RAN设备可以由一个节点实现无线资源控制(radio resource control，RRC)、分组数据汇聚层协议(packet data convergence protocol，PDCP)、无线链路控制(radio link control，RLC)、和媒体接入控制(media access control，MAC)等协议层的功能；或者可以由多个节点实现这些协议层的功能；例如，在一种演进结构中，RAN设备可以包括集中单元(centralized unit，CU)和分布单元(distributed unit，DU)，多个DU可以由一个CU集中控制。如图2所示，CU和DU可以根据无线网络的协议层划分，例如PDCP层及以上协议层的功能设置在CU，PDCP以下的协议层，例如RLC层和MAC层等的功能设置在DU。
这种协议层的划分仅仅是一种举例，还可以在其它协议层划分，例如在RLC层划分，将RLC层及以上协议层的功能设置在CU，RLC层以下协议层的功能设置在DU；或者，在某个协议层中划分，例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外，也可以按其它方式划分，例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。
此外，射频装置可以拉远，不放在DU中，也可以集成在DU中，或者部分拉远部分集成在DU中，在此不作任何限制。
请继续参考图3，图3示出了本申请实施例提供的另一种网络架构的示意图，相对于图2所示的架构，还可以将CU的控制面(CP)和用户面(UP)分离，分成不同实体来实现，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。
在以上网络架构中，CU产生的信令可以通过DU发送给终端设备，或者终端设备产生的信令可以通过DU发送给CU。DU可以不对该信令进行解析而直接通过协议层封装而透传给终端设备或CU。以下实施例中如果涉及这种信令在DU和终端设备之间的传输，此时，DU对信令的发送或接收包括这种场景。例如，RRC或PDCP层的信令最终会处理为PHY层的信令发送给终端设备，或者，由接收到的PHY层的信令转变而来。在这种架构下，该RRC或PDCP层的信令，即也可以认为是由DU发送的，或者，由DU和射频 发送的。
在以上实施例中CU划分为RAN侧的网络设备，此外，也可以将CU划分为CN侧的网络设备，在此不做限制。
本申请以下实施例中的装置，根据其实现的功能，可以位于终端设备。当采用以上CU-DU的结构时，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的RAN设备。

还应理解，该下行数据中可以包括一个或者多个传输块(transport block，TB)。
S220，该终端设备确定第一序列或者第二序列，其中，该第一序列为该终端设备对该下行数据接收成功时确定的序列；该第二序列为该终端设备对该下行数据没有接收成功时确定的序列；该第一序列的幅值和该第二序列的幅值不同。

例如，当该下行数据中仅包括一个传输块时，若该终端设备对该传输块接收成功，该终端设备可以向网络设备发送第一序列；若该终端设备对该传输块没有成功接收时，该终端设备可以向该网络设备发送第二序列。
又例如，当该下行数据中包括两个传输块时，若该终端设备对这两个传输块都接收成功时，该终端设备可以向该网络设备发送第一序列；若该终端设备对这两个传输块中的一个传输块接收成功，另一个传输块没有接收成功，或者对这两个传输块都没有接收成功时，该终端设备可以向网络设备发送第二序列。

例如，该反馈信息的比特取值为0表示否定应答消息(NACK)；该反馈信息的比特取值为1表示肯定应答消息(ACK)。
例如，该下行数据中包括一个或者多个传输块，该终端设备可以为该一个或者多个传输块中每一个传输块生成1bit反馈信息。如果该终端设备对传输块接收成功，则确定反馈信息的比特取值为1；如果该终端设备对传输块接收失败，则确定反馈信息的比特取值为0。
又例如，该下行数据中包括两个传输块，如果该终端设备对这两个传输块都接收成功，则确定反馈信息的比特取值为1；如果该终端设备只对这两个传输块中的一个传输块接收成功，则确定反馈信息的比特取值为0；如果该终端设备对这两个传输块都接收失败，则确定反馈信息的比特取值为0。
又例如，该下行数据中包括两个传输块，如果该终端设备对这两个传输块都接收成功，则确定反馈信息的比特取值为11；如果该终端设备只对这两个传输块中第一个传输块接收成功且第二个传输块接收失败，则确定反馈信息的比特取值为10；如果该终端设备只对这两个传输块中第一个传输块接收失败且第二个传输块接收成功，则确定反馈信息的比特取值为01；如果该终端设备对这两个传输块都接收失败，则确定反馈信息的比特取值 为00。

可选地，该终端设备根据该第一调制方式，将该反馈信息的比特映射为复值符号之前，该方法还包括：

应理解，该第一序列的幅值为0也可以理解为该第一序列中每个元素的幅值均为0。
当反馈信息的比特取值为0时，复值符号

应理解，该第二序列的幅值为1也可以理解为该第二序列中每个元素的幅值为1。
又例如，终端设备生成2比特的反馈信息且调制方式为多比特的OOK调制方式时，当反馈信息的比特取值为11时，复值符号d(i)＝0，该终端设备可以根据公式(3)和公式(4)确定该第一序列。若

本申请实施例中的传输信息的方法，终端设备可以根据对下行数据接收成功或者接收不成功，从而确定不同幅值的序列，有助于降低幅值较低的序列对应的应答消息所带来的上行控制信道的干扰，提高网络设备接收准确性。
图14示出了本申请实施例的传输信息的方法300的示意性流程图，如图14所示，该方法300的执行主体可以是传输信息的装置(例如，终端设备或者终端设备的芯片或者装置、网络设备或者网络设备的芯片或者装置)，该方法300包括：
S310，终端设备接收网络设备发送的下行数据。
例如，终端设备可以接收网络设备按照预定周期发送的下行数据。该终端设备可以在第一个预定周期内接收下行数据1以及调度该下行数据的DCI，该DCI可以指示该终端设备在以后的每个预定周期内接收下行数据。在以后的每个预定周期中，终端设备接收下行数据且没有接收调度该下行数据的DCI。例如，在第二个预定周期中，该终端设备可以接收下行数据2且没有接收调度该下行数据2的DCI；在第三个预定周期中，该终端设备可以接收下行数据3且没有接收调度该下行数据3的DCI。
又例如，网络设备通过高层信令(例如，RRC信令)配置周期发送下行数据。在这种情况下，网络设备周期的发送下行数据给终端设备，且无需再发送下行控制信息。终端设备在每个接收下行数据的资源上接收下行数据且没有接收调度该数据的下行控制信息。又例如，网络设备按照预定周期下发下行数据和调度下行数据的DCI，终端设备可以接收网络设备按照预定周期发送的下行数据，且该终端设备在每个预设周期内接收下行数据之前接收调度该下行数据的DCI。
S320，该终端设备对该下行数据没有成功接收时，该终端设备向该网络设备发送第一信息；该终端设备对该下行数据接收成功时，该终端设备不向该网络设备发送该第一信息。
例如，对于网络设备仅在第一个预定周期内下发调度下行数据的DCI的情况，或者，网络设备周期的发送下行数据给终端设备且无需发送DCI的情况，终端设备可以在对该下行数据没有成功接收时，可以向该网络设备发送第一信息；该终端设备对该下行数据接收成功时，该终端设备不向该网络设备发送该第一信息。
图15示出了终端设备反馈第一信息的示意图，如图15所示，在第一个预定周期中，终端设备对下行数据1成功接收，则该终端设备在上行资源1上不发送第一信息；该第N个预定周期中，终端设备对下行数据N没有成功接收，则该终端设备在上行资源N上发送第一信息。N为大于1的正整数。
可选的，该第一信息可以为复值符号组。
该终端设备在对该下行数据没有成功接收时，可以先确定反馈信息比特(例如，反馈信息比特可以为0)，该终端设备可以对该反馈信息比特进行信道编码、调制后，生成复值符号组，并向网络设备发送该复值符号组；该终端设备在对该下行数据接收成功时，可以不生成反馈信息比特，从而也不会向网络设备发送复值符号组。
可选地，该第一信息可以为序列。
当该第一信息为序列时，当终端设备对该下行数据没有接收成功时，该终端设备可以向该网络设备发送第二序列；当该终端设备对该下行数据接收成功时，该终端设备可以不向该网络设备发送第一信息。
应理解，该终端设备对该下行数据没有接收成功时，可以先确定第二序列，确定第二序列的过程可以参考上述方法200中的描述，为了简洁，在此不再赘述。
还应理解，当该终端设备对该下行数据接收成功时，该终端设备可以不向该网络设备发送信息，也可以理解为该终端设备对该下行数据接收成功时，不生成对应的反馈信息比特，从而也不会向该网络设备发送该第一信息。
例如，该终端设备确定反馈信息的比特长度为1bit，当反馈信息的比特取值为0时，该终端设备向该网络设备发送该第二序列；当反馈信息的比特取值为1时，该终端设备不 向该网络设备发送第一信息。
又例如，该终端设备确定反馈信息的比特长度为2bit，当反馈信息的比特取值为00、01或者10时，该终端设备向该网络设备发送该第二序列；当反馈信息的比特取值为11时，该终端设备可以不向该网络设备发送第一信息。
又例如，该终端设备确定反馈信息的比特长度为2bit，当反馈信息的比特取值为00时，该终端设备向该网络设备发送第二序列；当反馈信息的比特取值为01时，该终端设备向该网络设备发送第三序列；当反馈信息的比特取值为10时，该终端设备向该网络设备发送第四序列；当反馈信息的比特取值为11时，该终端设备可以不向该网络设备发送第一信息。
应理解，该第二序列、第三序列和第四序列可以参考上述方法200中的描述，为了简洁，在此不再赘述。
还应理解，本申请实施例中，在该终端设备确定对该下行数据接收成功时，该终端设备不向网络设备发送第一信息还可以理解为该终端设备不向网络设备发送任何信息。
还应理解，对于终端设备在对该下行数据接收成功的情况，该终端设备在不生成对应的反馈信息比特，且无其他上行反馈信息时，该终端设备不发送任何信号或信息给网络设备。而该终端设备在不生成对应的反馈信息比特，且有其他上行反馈信息时，该终端设备仅发送该其他上行反馈信息。
例如，该其他上行反馈信息可以为终端设备对网络设备非周期性发送的下行数据的反馈信息；或者，该其他上行反馈信息还可以为终端设备在进行信道测量时生成的信道状态信息(channel state information，CSI)。
又例如，对于网络设备按照预定周期下发下行数据和调度下行数据的DCI的情况，终端设备可以在对该下行数据没有成功接收时，可以向该网络设备发送第一信息；终端设备在没有接收到调度下行数据的DCI时，可以向该网络设备发送第二信息；该终端设备对该下行数据接收成功时，该终端设备不向该网络设备发送该第一信息或者该第二信息。
当该终端设备确定反馈信息的比特长度为1bit，当反馈信息的比特取值为0时，该终端设备向该网络设备发送该第一信息；当反馈信息的比特取值为1时，表示终端设备没有成功接收调度下行数据的DCI，该终端设备可以向该网络设备发送第二信息；当终端设备确定对下行数据成功接收时，可以不向该网络设备发送该第一信息或者该第二信息。
可选地，该第一信息和该第二信息为不同幅值的序列。可选地，该终端设备向该网络设备发送第一信息，包括：
该终端设备在预定的上行资源上，向该网络设备发送该第一信息。
可选地，该终端设备向该网络设备发送第一信息，包括：

当该终端设备确定对该下行数据没有接收成功时，该终端设备可以从上行资源集合中竞争获得一个或者多个上行资源，并在该一个或者多个上行资源中的至少部分上行资源上，向该网络设备发送该第一信息。
S330，该网络设备接收该终端设备发送的第一信息时，该网络设备确定该终端设备对该下行数据没有成功接收；该网络设备没有接收到该终端设备发送的第一信息时，该网络设备确定该终端设备对该下行数据接收成功。
可选地，该网络设备接收该终端设备发送的第一信息，包括：
该网络设备在预定的上行资源上接收该第一信息。
可选地，该网络设备没有接收到该终端设备发送的第一信息，包括：

可选地，该网络设备接收该终端设备发送的第一信息，包括：
该网络设备在一个或者多个上行资源上接收到该终端设备发送的该第一信息。
网络设备可以配置上行资源集合来让终端设备竞争，该下行数据和该上行资源集合可以有对应关系。终端设备可以在从该上行资源集合中竞争获得一个或者多个上行资源上，并可以在竞争成功的该一个或者多个上行资源向该网络设备发送该第一信息，该网络设备在该上行资源集合中的每个上行资源上接收该第一信息，若该网络设备在上行资源集合中的每个上行资源上都没有接收到该第一信息，则该网络设备确定终端设备对该下行数据接收成功；若该网络设备在该上行资源集合中的一个或者多个上行资源上接收到该第一信息，则该网络设备确定该终端设备对该下行数据没有接收成功。
对于网络设备仅在第一个预定周期内下发调度下行数据的DCI的情况，或者，网络设备周期的发送下行数据给终端设备且无需发送DCI的情况，当网络设备接收到该第一信息时，可以向终端设备重传下行数据。
对于网络设备按照预定周期下发下行数据和调度下行数据的DCI的情况，当网络设备接收到该第一信息时，可以向终端设备重传下行数据以及调度该下行数据的DCI；当网络设备接收到该第二信息时，可以向终端设备重传下行数据。
