Description

无线通信的方法和终端设备 技术领域
本申请实施例涉及通信领域，具体涉及一种无线通信的方法和终端设备。
背景技术
在非授权频谱上，通信设备遵循“先听后说(Listen Before Talk，LBT)”原则，即通信设备在非授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在非授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。
非授权频段上的NR(NR-based access to unlicensed spectrum，NR-U)系统支持基于全部混合自动请求重传(Hybrid Automatic Repeat reQuest，HARQ)进程进行确认/否定确认(ACKnowledgement/Negative ACKnowledgement，ACK/NACK)反馈的方式。具体地，若终端设备支持最多N个HARQ进程，当网络设备触发终端设备进行全部HARQ进程的反馈时，不论终端设备实际接收到多少个HARQ进程，都需要向网络设备反馈该N个进程对应的ACK/NACK信息。
这种情况下，若网络设备先后使用同一HARQ进程进行调度传输，并且终端设备只接收到第一次调度的数据，未接收到第二次调度的数据，则进行反馈时，终端设备反馈的是第一次调度的数据的反馈信息，而网络设备以为终端设备反馈的是第二次调度的数据的反馈信息，若第一次调度的数据的反馈信息为ACK，这种理解的不一致导致会导致网络设备以为第二次调度的数据传输成功而不再进行重传，导致数据丢失，影响用户体验。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然， 所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请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，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、非授权频段上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。

该通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。作为在此使用的“终端设备”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端设备的被设置成接收/发 送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、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。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、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
可选地，终端设备120之间可以进行设备到设备(Device to Device，D2D)通信。
可选地，5G系统或5G网络还可以称为新无线(New Radio，NR)系统或NR网络。
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，本申请实施例对此不作限定。
应理解，本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例，通信设备可包括具有通信功能的网络设备110和终端设备120，网络设备110和终端设备120可以为上文所述的具体设备，此处不再赘述；通信设备还可包括通信系统100中的其他设备，例如网络控制器、移动管理实体等其他网络实体，本申请实施例中对此不做限定。
应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种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。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
在NR-U系统中，终端设备确定支持基于全部混合自动请求重传(Hybrid Automatic Repeat reQuest，HARQ)进程进行确认/否定确认(ACKnowledgement/Negative  ACKnowledgement，ACK/NACK)反馈的方式。
具体地，终端设备支持最多N个HARQ进程，当网络设备触发终端设备进行全部HARQ进程的反馈时，不论终端设备实际接收到多少个HARQ进程，都需要向网络设备反馈该N个进程对应的ACK/NACK信息。其中，每个HARQ进程的ACK/NACK信息可以按照HARQ进程的编号顺序依次映射到反馈信息码本(codebook)中。终端设备未接收到的HARQ进程所对应的ACK/NACK信息设置为占位信息(如NACK)。
假设终端设备最多支持8个HARQ进程，一个HARQ进程每次通过一个物理下行共享信道(Physical Downlink Shared Channel，PDSCH)传输。终端设备支持的最大传输块(Transport Block，TB)数量为2(即一个PDSCH中最多承载2个TB)，每个TB对应独立的ACK/NACK信息。
若终端接收到HARQ进程3、HARQ进程7和HARQ进程4，当网络设备触发终端设备进行全HARQ进程的反馈时，终端设备在PUCCH内传输如下反馈信息：{NACK HARQ0,TB0,NACK HARQ0,TB1,NACK HARQ1,TB0,NACK HARQ1,TB1,NACK HARQ2,TB0,NACK HAR Q2,TB1,b HARQ3,TB0,b HARQ3,TB1,b HARQ4,TB0,b HARQ4,TB1,NACK HARQ5,TB0,NACK HARQ5,TB1,NACK HARQ6, TB0,NACK HARQ6,TB1,b HARQ7,TB0,b HARQ7,TB1}，其中，b HARQi,TBj表示HARQ进程i中TBj对应的ACK/NACK信息。
在一些场景中，网络设备第一次调度通过HARQ进程3传输TB a，后来又调度HARQ进程3传输新的传输块TB b，此时调度该HARQ进程3的下行控制信令(Downlink Control Information，DCI)中的新数据指示(New Data Indicator，NDI)相对于上一次调度发生翻转，若终端设备接收到TB a而没有接收到TB b。这种情况下，若网络设备指示终端设备进行全HARQ进程反馈时，针对HARQ进程3，终端设备反馈TB a对应的ACK/NACK信息，而网络设备以为终端设备发送的是TB b对应的ACK/NACK信息。由于该HARQ进程3被重新调度数据，通常是TB a已经被正确接收，即对应的反馈信息为ACK。这种终端设备和网络设备的理解分歧会造成网络设备以为TB b被正确接收而不再重传TB b，从而造成数据丢失，影响用户体验。
在一些实施例中，可以通过上报NDI信息避免上述理解的分歧，具体地，网络设备在触发终端设备进行全部HARQ进程反馈时，进一步指示每个HARQ进程对应的NDI信息，或者在终端设备上报反馈信息时将每个HARQ进程的NDI信息一起上报给网络设备。但是，这种反馈方式导致终端设备的反馈信令的开销很大，影响反馈信息的传输。
有鉴于此，本申请实施例提供了一种反馈方式，有利于实现反馈开销和网络设备与终端设备的理解的一致的平衡。
图2为本申请实施例提供的一种无线通信的方法200的示意性流程图。该方法200可以由图1所示的通信系统中的终端设备执行，如图2所示，该方法200可以包括如下至少部分内容：
S210，终端设备接收第一信令，所述第一信令用于指示所述终端设备发送所述终端设备支持的全部混合自动请求重传HARQ进程的反馈信息；
S220，所述终端设备根据所述第一信令中是否包括M个信道组中的每个信道组的新反馈指示信息NFI，确定生成第一反馈信息码本还是第二反馈信息码本，其中，所述第一反馈信息码本只包括所述全部HARQ进程中的每个HARQ进程对应的反馈信息，所述第二反馈信息码本包括所述全部HARQ进程中的每个HARQ进程对应的反馈信息和所述每个HARQ进程对应的新数据指示信息NDI，所述每个信道组包括至少一个信道，所述M为大于1的正整数。
在本申请实施例中，所述M为所述终端设备支持的信道组的最大数量，作为一个具体示例，所述M为2，以下，在具体示例中以M等于2进行说明，但本申请实施例并不限于此。
在本申请实施例中，所述全部HARQ进程的数量可以根据终端设备配置的载波的工作模式和每个载波上终端设备支持的最大HARQ进程数确定。
作为一个示例，所述终端设备被配置为单载波工作模式，则全部HARQ进程的数量可以根据该单载波(例如载波1)上终端设备支持的最大HARQ进程的数量确定，例如，该载波1上终端设备支持16个HARQ进程，则全部HARQ进程为16个。
作为另一示例，所述终端设备被配置为载波聚合模式，则全部HARQ进程的数量可以根据该多个载波(例如载波1和载波2)上终端设备支持的最大HARQ进程的数量确定，例如，该载波1上终端设备支持16个HARQ进程，载波2上终端设备最多支持8个HARQ进程，则全部HARQ进程为24个。
在本申请一些实施例中，所述第一信令可以为任一下行信令，例如，DCI，所述DCI可以用于指示所述终端设备发送全部HARQ进程的反馈信息(one-shot feedback)。即无论终端设备实际接收到多少个HARQ进程，都需要向网络设备反馈全部HARQ进程的反馈信息。其中，未接收到的HARQ进程的反馈信息可以设置为占位信息，例如NACK。
在一些实施例中，所述第一信令可以包括M个新反馈指示信息(New Feedback Indicator，NFI)，对应所述M个信道组。
在另一些实施例中，所述第一信令可以包括所述M个信道组中的部分信道组的NFI，或者不包括NFI。
可选地，在该第一信令中，该M个NFI可以按照一定的顺序排列，例如，按照对应的信道组的编号排列，以便终端设备确定每个信道组对应的NFI。
在本申请实施例中，所述M个信道组中的每个信道组可以包括至少一个信道，每个信道组中的信道可以为PDCCH或者PDSCH。终端设备可以接收所述M个信道组中的每个信道组中的至少一个信道，从接收的信道中获取该信道所属的信道组的信息以及该信道组对应的NFI。
在本申请一些实施例中，所述S220可以包括：
若所述第一信令中包括M个信道组中的每个信道组的NFI，确定生成所述第一反馈信息码本；或
若所述第一信令中只包括M个信道组中的部分信道组的NFI或不包括NFI，确定生成所述第二反馈信息码本。
在所述第一信令包括所有的信道组中的每个信道组的NFI的情况下，反馈信息码本中不包括HARQ进程对应的NDI，也可以保证终端设备和网络设备对反馈信息的理解的一致，因此，所述终端设备生成的反馈信息码本中可以只包括每个HARQ进程的反馈信息不包括NDI，有利于降低反馈开销。
并且，在第一信令中只包括部分信道组的NFI或不包括NFI的情况下，生成的反馈信息码本中包括每个HARQ进程对应的反馈信息和NDI，能够保证终端设备和网络设备对反馈信息的理解的一致。
例如，对于前文所述的TB b的反馈，在本申请实施例中，所述终端设备可以将TB a的反馈信息和承载该TB a的HARQ进程3对应的NDI一起发送给网络设备，从而网络设备可以根据该反馈信息和该NDI，确定该反馈信息所对应的数据，由于传输TB a和TB b时HARQ进程3对应的NDI不同，据此上报的反馈信息可以区分是哪个数据的反馈信息。
在本申请实施例中，所述第一反馈信息码本中的反馈信息为N个信道组的反馈信息，所述N个信道组中的信道组的NFI与所述M个信道组中的信道组的NFI相同。
例如，所述M个信道组包括第一信道组，所述第一反馈信息码本中可以包括与所述第一信道组的NFI相同的信道组的反馈信息。
若确定生成所述第一反馈信息码本，所述终端设备可以根据载波工作模式确定第一反馈信息码本中的反馈信息的排列顺序。
作为一个实施例，若所述终端设备被配置为单载波工作模式，即所述全部HARQ进程为同一载波上，所述终端设备可以将所述全部HARQ进程对应的反馈信息按照HARQ 进程的进程号顺序排列以得到所述第一反馈信息码本。
可选地，若在该载波上一个PDSCH中能传输多个TB，对于每个HARQ进程，还可以按照TB的顺序排列每个TB对应的反馈信息。
作为另一实施例，若所述终端设备被配置为载波聚合的工作模式，所述全部HARQ进程在多个载波上，所述终端设备按照先载波号后HARQ进程号的顺序排列所述多个载波中的每个载波上的HARQ进程所对应的反馈信息以得到所述第一反馈信息码本。可选地，若在载波上一个PDSCH中能传输多个TB，对于每个HARQ进程，还可以按照TB的顺序排列每个TB对应的反馈信息。
作为一个例子，若所述终端设备被配置了载波聚合的工作模式，其中，在载波1上终端设备最多支持16个HARQ进程且一个PDSCH中最多包括两个TB，在载波2上终端设备最多支持8个HARQ进程且一个PDSCH中最多包括一个TB，并且传输每个HARQ进程的PDSCH属于所述2个信道组中的一个。
若该第一信令包括2个信道组的NFI，并且所述第一信令还指示终端设备发送全部HARQ进程的反馈信息，则终端设备可以生成第一反馈信息码本。所述第一反馈信息码本可以包括16*2+8*1＝40比特的ACK/NACK信息，并且每个TB对应独立的ACK/NACK信息。
具体地，首先按照载波编号的顺序，然后在每个载波内，按照HARQ进程号的顺序，每个HARQ进程内，按照TB的编号的顺序依次将对应的反馈信息映射到反馈码本对应的比特位上。则该第一反馈信息码本可以为：{o 1,1,1,o 1,1,2,o 1,2,1,o 1,2,2,……,o 1,16,1,o 1,16,2,o 2,1,1,o 2,2,1,……,o 2,8,1}其中，o i,j,k表示在载波i上，HARQ进程(编号)j中，TB块(编号)k对应的反馈信息。
在另一些实施例中，若确定生成所述第二反馈信息码本，所述终端设备可以根据载波工作模式确定第二反馈信息码本中的反馈信息的排列顺序。
作为一个实施例，若所述终端设备被配置为单载波工作模式，即所述全部HARQ进程在同一载波上，所述终端设备可以将所述全部HARQ进程中的每个HARQ进程对应的反馈信息和NDI按照HARQ进程的进程号顺序排列以得到所述第二反馈信息码本。
即所述终端设备可以向所述网络设备反馈每个HARQ进程对应的反馈信息和NDI，以便于网络设备确定该反馈信息对应的信道。可选地，若在载波上一个PDSCH中能传输多个TB，对于每个HARQ进程，还可以按照TB的顺序排列每个TB对应的反馈信息和NDI。
作为另一实施例，若所述终端设备被配置为载波聚合的工作模式，所述全部HARQ 进程在多个载波上，所述终端设备可以按照先载波号后HARQ进程号的顺序排列所述多个载波中的每个载波上的HARQ进程所对应的反馈信息和NDI以得到所述第二反馈信息码本。可选地，若在载波上一个PDSCH中能传输多个TB，对于每个HARQ进程，还可以按照TB的顺序排列每个TB对应的反馈信息和NDI。
作为一个例子，若终端设备被配置了载波聚合模式，其中，在载波1上终端设备最多支持16个HARQ进程且一个PDSCH中最多包括两个TB，在载波2上终端设备最多支持8个HARQ进程且一个PDSCH中最多包括一个TB，并且传输每个HARQ进程的PDSCH属于所述2个信道组中的一个。
若该第一信令用于调度第一PSDCH，该第一PDSCH属于第一信道组，所述第一信令包括一个NFI，对应所述第一信道组，或者所述第一信令不包括NFI，并且所述第一信令还指示终端设备发送全部HARQ进程的反馈信息，则终端设备可以生成第二反馈信息码本。
基于上述配置，所述第二反馈信息码本可以包括16*2*2+8*1*2＝80比特的ACK/NACK信息，并且每个TB对应独立的ACK/NACK信息和NDI。
具体地，先按照载波编号的顺序，然后在每个载波内，按照HARQ进程号的顺序，每个HARQ进程内，按照TB的编号的顺序依次将对应的反馈信息和NDI映射到反馈码本中对应的比特位上。则该第二反馈信息码本为：{o 1,1,1,NDI 1,1,1，o 1,1,2,NDI 1,1,2，o 1,2,1,NDI 1,2,1，o 1,2,2,NDI 1,2,2，……,o 1,16,1,NDI 1,16,1，o 1,16,2,NDI 1,16,2，o 2,1,1,NDI 2,1,1，o 2,2,1,NDI 2,2,1……,o 2,8,1，NDI 2,8,1}其中，o i,j,k表示在载波i上，HARQ进程(编号)j中，TB块(编号)k对应的反馈信息，NDI i,j,k表示在载波i上，HARQ进程(编号)j中，TB块(编号)k对应的NDI。
在本申请实施例中，每个HARQ进程的反馈信息为传输该HARQ进程的信道的反馈信息，将HARQ进程的反馈信息映射到码本中可以为将该信道的反馈信息映射到码本中。
例如，所述全部HARQ进程包括第一HARQ进程，所述第一HARQ进程通过所述M个信道组中的第一信道组中的信道传输，则所述第一HARQ进程的反馈信息根据传输所述第一HARQ进程的信道的反馈信息确定，其中，所述第一信道组对应的NFI和所述第一信令中指示的所述第一信道组对应的NFI相同。
作为一个示例，若所述第一HARQ进程通过所述第一信道组中的一个信道传输，则所述终端设备根据所述一个信道的接收情况，确定所述第一HARQ进程的反馈信息。若所述一个信道接收成功，确定所述第一HARQ进程的反馈信息为ACK，否则为NACK。
作为另一个示例，若所述第一HARQ进程通过所述第一信道组中的多个信道传输，则所述终端设备根据所述多个信道传输的传输块TB是否相同以及所述多个信道的接收情况，确定所述第一HARQ进程的反馈信息。
若所述多个信道用于传输相同的TB，则任一信道接收正确，所述第一HARQ进程的反馈信息即为ACK，或者，若所述多个信道都接收失败，则所述第一HARQ进程的反馈信息为NACK；或者
若所述多个信道传输用于不同的传输块TB，所述终端设备确定所述第一HARQ进程的反馈信息为所述多个信道中传输时间最晚的TB的反馈信息。若传输时间最晚的TB接收正确，则确定所述第一HARQ进程的反馈信息为ACK，否则，确定所述第一HARQ进程的反馈信息为NACK。
因此，在本申请实施例中，当触发终端设备发送全部HARQ进程的反馈信息的信令中包括每个信道组的NFI时，所述终端设备上报的反馈信息码本中可以只包括HARQ进程的反馈信息，能够降低开销，提升系统效率，同时还可以保证网络设备和终端设备对于反馈信息的理解的一致。
并且，在当触发终端设备发送全部HARQ进程的反馈信息的信令中包括部分信道组的NFI或不包括NFI时，所述终端设备上报的反馈信息码本中可以包括每个HARQ进程的反馈信息和NDI，能够保证网络设备和终端设备对于反馈信息的理解的一致。
