Description

发送、接收反馈信息的方法和设备 技术领域
本申请实施例涉及通信领域,并且更具体地,涉及发送、接收反馈信息的方法和设备。
背景技术
新空口(New Radio,NR)第15版本(Rel-15)支持两种混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)-确认(ACK)的码本(codebook)生成方式。即,半静态HARQ-ACK codebook生成方式和动态HARQ-ACK codebook生成方式。
其中,在动态HARQ-ACK codebook生成方式中,终端设备需要根据下行控制信息(Downlink Control Information,DCI)中的下行分配索引(Downlink assignment index,DAI)确定实际的调度数量。例如,当终端设备只配置了单载波时,DAI信息域包括2比特的累计DAI(counter DAI,C-DAI)。当终端设备配置了多个下行载波时,DAI信息域包括4比特,其中2比特为C-DAI,2比特为总DAI(total DAI,T-DAI)。由此,终端设备能够根据基站的调度情况确定反馈信息的比特数量,降低反馈开销。其中,C-DAI的取值的物理意义是到当前载波当前物理下行控制信道(Physical Downlink Control Channel,PDCCH)检测位置为止被调度的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)或指示半永久性调度(Semi-Persistent Scheduling,SPS)资源释放的PDCCH的数量。T-DAI的取值的物理意义是到当前PDCCH检测位置为止被调度的PDSCH或指示SPS资源释放的PDCCH的总数量。
在NR-U***中,若沿用Rel-15C-DAI与T-DAI的计数方法,即不同载波联合统计。当某个载波上的先听后说(Listen Before Talk,LBT)失败后,针对这个载波上预先准备的数据不能够被传输。但由于DCI信息需要在发送数据前提前准备(编码、映射等物理层处理),而在准备DCI(统计C-DAI、T-DAI)时,并不能知道实际LBT结果,因此会造成C-DAI、T-DAI的计数结果比实际传输的PDSCH数量大,从而造成确认/非确认(acknowledgement/non-acknowledgement,ACK/NACK)反馈信息中存在大量的冗余信息,降低了反馈效率。

基于以上技术方案,通过第一信令可指示终端设备传输至少一个目标组对应的反馈信息时,由于终端设备以组为单位发送反馈信息,且所述至少一个目标组中的同一目标组对应的下行信道属于同一载波,因此,网络设备可以通过所述第一信令触发终端设备反馈由于LBT成功已在至少一个载波上成功传输的下行信道的反馈信息,避免了触发终端设备反馈由于LBT失败而未成功传输的下行信道的反馈信息,因此能够避免由于LBT失败造成的反馈信息中存在大量的冗余信息,进而提高了反馈效率。
换言之,通过所述第一信令,可以以一个载波对应的至少一组为单位触发终端设备反馈下行信道的反馈信息,而非以多个载波为单位触发终端设备反馈下行信道的反馈信息,避免了由于某个载波LBT失败会造成其反馈信息存在大量的冗余信息,能够提高反馈效率。

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。
图1是本申请实施例的一个应用场景的示意图。
如图1所示,通信***100可以包括终端设备110和网络设备120。网络设备120可以通过空口与终端设备110通信。终端设备110和网络设备120之间支持多业务传输。
应理解,本申请实施例仅以通信***100进行示例性说明,但本申请实施例不限定于此。也就是说,本申请实施例的技术方案可以应用于各种通信***,例如:长期演进(Long Term Evolution,LTE)***、LTE时分双工(Time Division Duplex,TDD)、通用移动通信***(Universal Mobile Telecommunication System,UMTS)、5G通信***(也称为新无线(New Radio,NR)通信***),或未来的通信***等。
在图1所示的通信***100中,网络设备120可以是与终端设备110通信的接入网设备。接入网设备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110(例如UE)进行通信。
网络设备120可以是长期演进(Long Term Evolution,LTE)***中的演进型基站(Evolutional Node B,eNB或eNodeB),或者是下一代无线接入网(Next Generation Radio Access Network,NG RAN)设备,或者是NR***中的基站(gNB),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该网络设备120可以为中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器,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。
终端设备110可以是任意终端设备,其包括但不限于与网络设备120或其它终端设备采用有线或者无线连接的终端设备。
例如,所述终端设备110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网络中的终端设备等。
终端设备110可以用于设备到设备(Device to Device,D2D)的通信。
无线通信***100还可以包括与基站进行通信的核心网设备130,该核心网设备130可以是5G核心网(5G Core,5GC)设备,例如,接入与移动性管理功能(Access and Mobility Management Function,AMF),又例如,认证服务器功能(Authentication Server Function,AUSF),又例如,用户面功能(User Plane Function,UPF),又例如,会话管理功能(Session Management Function,SMF)。可选地,核心网络设备130也可以是LTE网络的分组核心演进(Evolved Packet Core,EPC)设备,例如,会话管理功能+核心网络的数据网关(Session Management Function+Core Packet Gateway,SMF+PGW-C)设备。应理解,SMF+PGW-C可以同时实现SMF和PGW-C所能实现的功能。在网络演进过程中,上述核心网设备也有可能叫其它名字,或者通过对核心网的功能进行划分形成新的网络实体,对此本申请实施例不做限制。
通信***100中的各个功能单元之间还可以通过下一代网络(next generation,NG)接口建立连接实现通信。
例如,终端设备通过NR接口与接入网设备建立空口连接,用于传输用户面数据和控制面信令;终端设备可以通过NG接口1(简称N1)与AMF建立控制面信令连接;接入网设备例如下一代无线接入基站(gNB),可以通过NG接口3(简称N3)与UPF建立用户面数据连接;接入网设备可以通过NG接口2(简称N2)与AMF建立控制面信令连接;UPF可以通过NG接口4(简称N4)与SMF建立控制面信令连接;UPF可以通过NG接口6(简称N6)与数据网络交互用户面数据;AMF可以通过NG接口11(简称N11)与SMF建立控制面信令连接;SMF可以通过NG接口7(简称N7)与PCF建立控制面信令连接。
图1示例性地示出了一个基站、一个核心网设备和两个终端设备,可选地,该无线通信***100可以包括多个基站设备并且每个基站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。
应理解,本申请实施例中网络/***中具有通信功能的设备均可称为通信设备。以图1示出的通信***100为例,通信设备可包括具有通信功能的网络设备120和终端设备110,网络设备120和终端设备110可以为上文所述的设备,此处不再赘述;通信设备还可包括通信***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“***”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。
在本申请的一些实施例中,所述通信***可应用于NR网络。
换言之,所述终端设备100可支持动态确定混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)反馈时序。
具体而言,终端设备100首先确定预配置反馈时序集合,其中,预配置集合最多包括8个定时(timing)取值,对于下行控制信息(Downlink Control Information,DCI)格式1_0(format 1_0),该集合由协议约定,对于DCI format 1_1,该集合由网络设备配置。DCI中的物理下行共享信道-HARQ的反馈定时指示(Physical Downlink Shared Channel,PDSCH-to-HARQ_feedback timing indicator)信息域指示集合中的一个数值作k。该DCI调度的PDSCH的结束位置在时隙(slot)n,则对应的应答/非应答(ACK/NACK)信息在slot n+k中传输。
此外,所述终端设备110还可以支持两种混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)-确认(ACK)的码本(codebook)生成方式。即,半静态HARQ-ACK codebook生成方式和动态HARQ-ACK codebook生成方式。
在半静态HARQ-ACK codebook生成方式中,一个物理上行控制信道(Physical Uplink Control Channel,PUCCH)中承载的ACK/NACK信息比特数量半静态确定,而与实际的调度情况无关。本方式的优点在于基站与终端对反馈信息的理解能够保持一致,避免了理解歧义造成的接收错误。
在动态HARQ-ACK codebook生成方式中,终端设备需要根据下行控制信息(Downlink Control Information,DCI)中的下行分配索引(Downlink assignment index,DAI)确定实际的调度数量。例如,当终端设备只配置了单载波时,DAI信息域包括2比特的累计DAI(counter DAI,C-DAI)。当终端设备配置了多个下行载波时,DAI信息域包括4比特,其中2比特为C-DAI,2比特为总DAI(total DAI,T-DAI)。由此,终端设备能够根据基站的调度情况确定反馈信息的比特数量,降低反馈开销。其中,C-DAI的取值的物理意义是到当前载波当前物理下行控制信道(Physical Downlink Control  Channel,PDCCH)检测位置为止被调度的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)或指示半永久性调度(Semi-Persistent Scheduling,SPS)资源释放的PDCCH的数量。T-DAI的取值的物理意义是到当前PDCCH检测位置为止被调度的PDSCH或指示SPS资源释放的PDCCH的总数量。
图2是本申请实施例的DAI的示意性框图。
如图2所示,C-DAI和T-DAI分别指在载波0、载波1和载波2的基础上针对被调度的PDSCH或指示SPS资源释放的PDCCH的累计计数和总计数。
换言之,不同载波联合统计。
针对DCI格式1_0,采用半静态HARQ-ACK codebook生成方式时,可以存在DAI信息域。即虽然不使用该信息域,但依然存在DCI中。对于DCI格式1_1,采用动态HARQ-ACK codebook生成方式时,可以存在DAI信息域,否则不存在,其中T-DAI只会存在于DCI格式1_1中。
在本申请的另一些实施例中,所述通信***还可以适用于NR-U网络。
NR-U网络可以在免授权频谱上进行数据的传输。
免授权频谱是国家和地区划分的可用于无线电设备通信的频谱,该频谱通常被认为是共享频谱,即不同通信***中的通信设备只要满足国家或地区在该频谱上设置的法规要求,就可以使用该频谱,不需要向政府申请专有的频谱授权。为了让使用免授权频谱进行无线通信的各个通信***在该频谱上能够友好共存,一些国家或地区规定了使用免授权频谱必须满足的法规要求。例如,在一些地区,通信设备遵循“先听后说”原则,即通信设备在免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;如果通信设备在免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。为了保证公平性,在一次传输中,通信设备使用免授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupation Time,MCOT)。随着无线通信技术的发展,LTE***和NR***都会考虑在免授权频谱上布网,以利用免授权频谱来进行数据业务的传输。
NR-U可支持基于分组的ACK/NACK反馈方式。
例如,网络设备通过DCI指示该DCI调度的PDSCH或承载该DCI的PDCCH所属于的组信息。当网络设备发送第一信令,指示终端反馈某个组对应的ACK/NACK信息时,则终端将属于该组的所有PDSCH或PDCCH对应的反馈信息一起反馈给网络设备。网络设备可以多次触发终端发送某一个组的ACK/NACK信息,即实现ACK/NACK重传。为了保证基站与终端对一个分组对应的反馈信息比特数量理解一致,在每个组内独立的统计物理下行信道的C-DAI和T-DAI。DCI中可进一步包括新反馈指示(New feedback information,NFI)信息域,该信息的用于指示该DCI调度的PDSCH或承载该DCI的PDCCH所对应的组内的ACK/NACK信息被清除。
图3是本申请实施例的NFI和DAI之间的关系的示意性框图。
如图3所示,对于反馈组0对应NFI=0的三个DCI的ACK/NACK通过PUCCH成功反馈之后,网络设备可以在后续调度反馈组0时将NFI设置成1(比特翻转的工作方式),表示反馈组0重新开始组织,即将之前NFI=0对应ACK/NACK信息释放掉。
为了保证终端与网络设备对每个分组中包括的下行信道理解一致,第一信令中可以同时指示所触发组对应的NFI信息。即第一信令中可进一步包括触发组的NFI信息和/或T-DAI信息。
在NR-U***中,若沿用C-DAI与T-DAI的计数方法,即不同载波联合统计。当某个载波上的先听后说(Listen Before Talk,LBT)失败后,针对这个载波上预先准备的数据不能够被传输。然而,由于DCI信息需要在发送数据前提前准备(编码、映射等物理层处理),而在准备DCI(统计C-DAI、T-DAI)时,并不能知道实际LBT结果,因此会造成C-DAI、T-DAI的计数结果比实际传输的PDSCH数量大,从而造成ACK/NACK反馈信息中存在大量的冗余信息,降低了反馈效率。
图4是本申请实施例的LBT和DAI的关系的示意性框图。
如图4所示,当某个载波上的三个下行信道LBT失败后,针对这个载波上预先准备的数据不能够被传输。然而,其反馈信息仍然包括5比特信息{N,N,b3,N,b5},其中N为占位信息,b3、b5是有效ACK/NACK信息,即针对LBT成功的下行信道的反馈信息。
本申请提供了一种发送反馈信息的方法,通过第一信令可指示终端设备传输至少一个目标组对应的反馈信息时,使得所述至少一个目标组中的同一目标组对应的下行信道属于同一载波,由此,能够避免由于LBT失败造成的反馈信息中存在大量的冗余信息,进而提高反馈效率。
图2示出了根据本申请实施例的发送反馈信息或接收反馈信息的方法200的示意性流程图,该方法200可以由终端设备和网络设备交互执行。图2中所示的终端设备可以是如图1所示的终端设备,图2中所示的网络设备可以是如图1所示的接入网设备。
如图2所示,该方法200包括以下部分或全部内容:
S210,终端设备接收网络设备发送的第一信令,所述第一信令用于指示所述终端设备传输至少一个目标组对应的反馈信息,其中,所述至少一个目标组中的同一目标组对应的下行信道属于同一载波。
S220,所述终端向所述网络设备发送反馈信息码本,所述反馈信息码本中包括所述至少一个目标组对应的反馈信息。
例如,所述终端设备接收DCI,所述DCI包括所述第一信令。其中,所述反馈信息包括确认/非确认ACK/NACK反馈信息。所述下行信道包括PDCCH和/或PDSCH。
通过第一信令可指示终端设备传输至少一个目标组对应的反馈信息时,由于终端设备以组为单位发送反馈信息,且所述至少一个目标组中的同一目标组对应的下行信道属于同一载波,因此,网络设备可以通过所述第一信令触发终端设备反馈由于LBT成功已在至少一个载波上成功传输的下行信道的反馈信息,避免了触发终端设备反馈由于LBT失败而未成功传输的下行信道的反馈信息,因此能够避免由于LBT失败造成的反馈信息中存在大量的冗余信息,进而提高了反馈效率。
换言之,通过所述第一信令,可以以一个载波对应的至少一组为单位触发终端设备反馈下行信道的反馈信息,而非以多个载波为单位触发终端设备反馈下行信道的反馈信息,避免了由于某个载波LBT失败会造成其反馈信息存在大量的冗余信息,能够提高反馈效率。
例如,在NR-U载波聚合***中,基于分组进行ACK/NACK反馈时,一个反馈组内包含的下行信道(PDSCH或PDCCH)属于一个成员载波。一个成员载波内的不同PDSCH或PDCCH可以属于不同的反馈组。当终端收到网络设备发送的第一信令后,向网络设备反馈至少一个目标组对应的ACK/NACK信息时,所述至少一个目标组对应的下行信道(或满足处理时延的下行信道)的ACK/NACK信息同时传输。C-DAI、T-DAI在每一个目标组内分别统计。此时,调度信令中可以仅包括C-DAI。所述第一信令中可包括目标组的标识信息。例如T-DAI。
应理解,所述目标组可以是信道组也可以是反馈组,本申请对此不做限定。
例如,所述第一信令可以用于指示所述终端设备传输至少一个信道组对应的反馈信息。此时,网络设备在发送用于调度目标下行信道的调度信息时,所述调度信息可以包括所述目标下行信道在其所属的信道组中的计数。
又例如,所述第一信令可以用于指示所述终端设备传输至少一个反馈组对应的反馈信息。此时,网络设备在发送用于调度目标下行信道的调度信息时,所述调度信息可以包括所述目标下行信道的反馈信息在其所属的反馈组中的计数。
在本申请的一些实施例中,所述第一信令中包括第一组标识信息,所述第一组标识信息用于指示终端设备支持的A个组中的至少一个组,A为正整数;所述至少一个目标组包括所述第一组标识信息指示的至少一个组。
换言之,所述第一信令可以通过第一组标识信息指示所述至少一个目标组。
例如,若终端设备最多支持M个载波,则需要至少支持M个组。例如,若终端设备最多支持8个组,组编号为0~7,网络设备在载波上发送的目标物理信道时,所述目标物理信道对应所述8个组中的一个组。网络设备触发终端设备反馈所述目标物理信道的反馈信息时,第一信令中指示所述目标物理信道对应的组编号即可。
即,终端不期待属于不同载波的物理信道属于同一个组。
又例如,若终端设备最多支持M个载波,则需要至少支持M个组。为避免调度受限,则较优化地需要支持2M个组。此时,调度物理信道的DCI中可以包括log 2(2M)个比特指示该物理信道对应的组编号。所述第一信令中可以包括2M比特bitmap指示信息指示触发哪些组传输ACK/NACK信息。优选地,所述第一信令还用于指示每个触发组对应的x(较优地x=1)比特NFI信息和/或y(较优地y=2)比特T-DAI信息,则第一信令最多可包括(x+y)*M比特。
此时,所述方法200还可包括:
所述终端设备级联所述至少一个目标组对应的反馈信息,以得到所述反馈信息码本。
通过所述第一组标识指示所述至少一个目标信道,可以以一个载波对应的至少一组为单位触发终端设备反馈下行信道的反馈信息,而非以多个载波为单位触发终端设备反馈下行信道的反馈信息,可避免由于LBT不过造成的反馈信息中存在大量的冗余信息的问题,进而提高反馈效率。而且,终端和基站侧实现都比较简单,
应理解,本申请中的组标识信息可以是组的编号,也可以是用于指示组的编号的指示信息,还可以是与组的编号对应的标识信息。类似地,载波标识信息可以是载波的编号,也可以是用于指示载波编号的指示信息,还可以是与载波编号对应的标识信息。
在本申请的另一些实施例中,所述第一信令可以通过二维标识指示所述至少一个目标组。例如, 终端设备配置有5个载波,其载波的编号分别为0~4。每个载波内最多支持2个组,组编号(即第二组标识信息)为0、1。此时,每个组对应为{载波编号x,组编号y}。
作为一种示例,所述第一信令中包括第二组标识信息,所述第二组标识信息用于指示所述终端设备在一个载波内支持的B个组中的至少一个组,B为正整数,所述至少一个目标组包括第一载波内的所述第二组标识信息指示的至少一个组。可选地,所述第一载波为传输所述第一信令的载波,或者所述第一载波为传输所述第一信令调度的物理信道的载波,或者所述第一载波为所述第一信令中的载波标识信息所指示的载波。
换言之,可以通过第一载波的标识信息和第二组标识信息指示所述至少一个目标组。
例如,可以通过一个DCI触发终端传输一个载波内的至少一个组包含的ACK/NACK信息。具体而言,在载波x上发送的DCI或调度载波x上PDSCH传输的DCI可以触发载波x内的至少一个组。此时,DCI中可以仅包括组编号信息(即所述第二组标识信息),可以将用于传输所述一个DCI的载波或者用于传输所述一个DCI调度的物理信道的载波的编号确定为所述第一载波的编号(即所述第一载波的标识信息)。
其中,所述一个DCI可以用于指示传输所述一个载波内的至少一个组包含的ACK/NACK反馈所使用的物理上行控制信道PUCCH资源,包括时隙位置、时隙内时域符号位置、频域位置、扩频信令编号等。
终端设备在接收所述第一信令时,可以接收包括所述第一信令的多个信令。换言之,所述终端设备接收多个信令;其中,所述多个信令分别用于指示所述终端设备传输多个组对应的反馈信息,所述多个信令包括所述第一信令。
若所述多个组对应的反馈信息的资源重叠;所述终端设备级联所述多个组对应的反馈信息,以得到所述反馈信息码本。
例如,针对同一组内的下行信道对应的反馈信息,所述终端设备基于下行信道的下行分配索引DAI的顺序,级联所述同一组内的下行信道对应的反馈信息;和/或针对同一载波内的组对应的反馈信息,所述终端设备基于组的标识的顺序,级联所述同一载波内的组对应的反馈信息;和/或针对不同载波对应的反馈信息,所述终端设备基于载波的标识信息的顺序,级联所述不同载波对应的反馈信息。
换言之,若多个DCI指示的PUCCH资源重叠(时域重叠、时频域重叠)或完全相同时,所述多个PUCCH原本各自承载的ACK/NACK信息复用传输。多个PUCCH原本各自承载的ACK/NACK信息级联起来,联合编码后复用传输。级联可以按照载波编号顺序映射ACK/NACK信息,进一步的对每个载波按照组编号映射ACK/NACK信息,对于每个组按照DAI升序映射ACK/NACK信息。
以图6为例,载波2、1上分别触发反馈本载波内组0对应的ACK/NACK信息,并分别指示了PUCCH 1和PUCCH 2的资源,且二者时域重叠。则可以将载波2和载波1对应的反馈信息级联起来得到{b cc1,dai0,b cc1,dai1,b cc2,dai0,b cc2,dai1,b cc2,dai2},其中b cci,daij,表示载波i上DAI=j的下行信道对应的ACK/NACK信息。可以根据发送时间在后的第一信令确定传输级联信息的PUCCH。例如可以使用载波1上的第一信令确定的PUCCH 2。
在其他可替代实施例中,假设图6中所示的载波0上触发本载波内组1对应的ACK/NACK信息,并指示PUCCH 3资源。PUCCH 3与PUCCH1、2不重叠,终端设备可独立传输各个信令指示的目标组对应的反馈信息码本。
通过所述第二组标识信息,可以以一个载波对应的至少一组为单位触发终端设备反馈下行信道的反馈信息,而非以多个载波为单位触发终端设备反馈下行信道的反馈信息,避免了由于LBT失败造成的反馈信息中存在大量的冗余信息的问题,能够提高反馈效率。
而且,DCI信令开销较小,调度物理信道的DCI中需要包括1比特(假设每个载波最多支持2个组)第二组标识信息指示该物理信道对应的组编号。而第一信令中仅需要包括1比特信息指示触发哪些组传输ACK/NACK信息(例如指示“0”表示触发该DCI所调度的物理信道所在组的ACK/NACK反馈信息,“1”表示触发2个组的ACK/NACK信息)。由于一个第一信令可触发的组的数量少(每个载波内支持的组数量,如2),若第一信令中进一步包括NFI和T-DAI信息,其开销也较小。
需要说明的是,通过所述第二组标识信息指示所述至少一个目标组时,网络设备和终端设备有可能对反馈信息存在理解歧义。例如,假设图3中终端涩北没有争取接收到载波2上的第一信令,则终端设备会在PUCCH 2中只发送载波1对应的反馈信息,但网络设备期待接收载波2和载波1对应的反馈信息。但由于DCI信令丢失的概率较小,此问题对***整体影响较小。另外,也可以通过网络设备的调度避免网络设备和终端设备对反馈信息存在理解歧义,例如,将不同载波的PUCCH尽量调度在不同的时域资源上,使其不重叠发送反馈信息。
作为另一示例,所述第一信令中包括第一载波标识信息和第三组标识信息;所述第一载波标识信息用于指示终端设备支持的多个载波中的至少一个载波;所述第三组标识信息用于指示所述至少一个载波中每一个载波支持的C个组中的至少一个组,C为正整数;所述至少一个目标组包括所述至少一个载波中的所述第三组标识信息针对每一个载波指示的至少一个组。
换言之,可以通过所述第一载波标识信息和所述第三组标识信息,在二维上指示所述至少一个目标组。
例如,假设终端设备可支持M个载波且每个载波内最多支持N个组,第一信令最多可包括(M+1)*N比特信息,用于指示触发了哪些载波上的哪些组,即M比特的bitmap指示载波信息,每个载波对应N比特的bitmap指示组信息。即,一个第一信令DCI可触发的组的数量多为M*N个。进一步地,第一信令还可包括NFI和T-DAI信息。
进一步地,所述方法200还可包括:
所述终端设备级联所述至少一个载波中的所述第三组标识信息针对每一个载波指示的至少一个组对应的反馈信息,以得到所述反馈信息码本。
例如,针对同一组内的下行信道对应的反馈信息,所述终端设备基于下行信道的下行分配索引DAI的顺序,级联所述同一组内的下行信道对应的反馈信息;和/或针对同一载波内的组对应的反馈信息,所述终端设备基于组的标识的顺序,级联所述同一载波内的组对应的反馈信息;和/或针对不同载波对应的反馈信息,所述终端设备基于载波的标识信息的顺序,级联所述不同载波对应的反馈信息。
换言之,一个DCI(即所述第一信令)可触发终端传输多个载波内的组。所述一个DCI中可包括所述多个载波的编号信息(即所述第一载波标识信息)及载波内的组编号信息(即所述第三组标识信息)。此时,反馈信息可以按照触发的载波的载波编号顺序映射ACK/NACK信息,每个载波内进一步可以按照触发的组编号顺序映射,每个组内进一步可以按照DAI升序顺序映射。
以图7为例,调度物理信道传输的DCI中指示载波0及组0,载波2及组0和1,则终端设备可以在PUCCH中反馈载波0上组0和载波2上组0和1对应的ACK/NACK信息,即{b cc0,group0,dai0,b cc0,group0,dai1,b cc2,group0,dai0,b cc2,group0,dai1,b cc2,group1,dai0},其中b cci,groupj,daik为载波i上组j内C-DAI=k的物理信道对应的ACK/NACK信息。
通过所述第一载波标识信息和所述第三组标识信息,可以以一个载波对应的至少一组为单位触发终端设备反馈下行信道的反馈信息,而非以多个载波为单位触发终端设备反馈下行信道的反馈信息,避免了由于LBT失败造成的反馈信息中存在大量的冗余信息的问题,能够提高反馈效率。
而且,调度物理信道的DCI信令开销较小,能够降低信令开销。
此外,网络设备和终端设备对PUCCH中承载的反馈信息不会存在理解歧义。
作为另一示例,所述第一信令包括第二载波标识和第四组标识信息;所述第二载波标识用于指示所述终端支持的多个载波中除第一载波之外的其他载波中的至少一个载波;所述第四组标识用于指示所述第一载波内支持的D个组的至少一个组,D为正整数;所述第一载波为传输所述第一信令的载波,或者所述第一载波为传输所述第一信令调度的物理信道的载波;所述至少一个目标组包括所述第一载波内的所述第四组标识指示的至少一个组。
换言之,通过所述第二载波标识和所述第四载波标识可指示所述至少一个目标组。
进一步地,所述方法200还可包括:
所述终端设备级联所述至少一个载波对应的全HARQ进程反馈信息与所述至少一个目标组对应的反馈信息,以得到反馈信息码本。
例如,针对所述至少一个目标组对应的反馈信息,所述方法200还可包括:
针对同一组内的下行信道对应的反馈信息,所述终端设备基于下行信道的下行分配索引DAI的顺序,级联所述同一组内的下行信道对应的反馈信息;和/或,针对同一载波内的组对应的反馈信息,所述终端设备基于组的标识的顺序,级联所述同一载波内的组对应的反馈信息。
又例如,针对所述至少一个载波对应的全HARQ进程反馈信息,所述方法200还可包括:
针对同一载波对应的全部HARQ进程反馈信息,所述终端设备基于HARQ进程编号的顺序,级联所述同一载波内的全部HARQ进程对应的反馈信息;和/或,针对不同载波对应的反馈信息,所述终端设备基于载波的标识信息的顺序,级联所述不同载波对应的反馈信息。
其中,所述反馈信息码本中所述至少一个载波对应的全HARQ进程反馈信息在所述至少一个目标组对应的反馈信息之前或之后。
例如,一个DCI可触发终端传输本载波内的组对应的ACK/NACK信息,进一步的可触发反馈其他载波全HARQ进程反馈。具体的,第一信令中包括本载波内的组指示信息(即所述第四组标识信 息)及其他载波编号信息。对于其他载波,终端设备可发送该载波上所支持的所有HARQ进程对应的ACK/NACK信息。反馈信息可按照如下顺序进行映射,首先映射本载波组对应的ACK/NACK信息,具体的,可按照组编号映射ACK/NACK信息,对于每个组内的ACK/NACK信息,按照DAI升序映射ACK/NACK信息;然后,可按照其他载波的载波编号顺序映射ACK/NACK信息。
以图8为例,载波2上发送的第一信令中触发本载波的组1,和载波0和1,则终端设备可在PUCCH中发送的反馈信息为{b cc2,group1,dai0,b cc0,HARQ0,b cc0,HARQ1,……,b cc0,HARQ7,b cc1,HARQ0,b cc1,HARQ1,……,b cc1,HARQ7},其中b cc2,group1,dai0为载波2上组1内C-DAI=0的物理信道对应的ACK/NACK信息,b cci, HARQj表示载波i上HARQ进程j对应的ACK/NACK反馈信息。
通过所述第二载波信息和所述第四组标识信息,可以以一个载波对应的至少一组为单位触发终端设备反馈下行信道的反馈信息,而非以多个载波为单位触发终端设备反馈下行信道的反馈信息,避免了由于某个载波LBT,反馈信息中存在该载波对应的冗余信息的问题,能够提高反馈效率。
而且,调度物理信道的DCI信令开销较小,即第一信令开销较小。若第一信令中包括NFI和T-DAI信息,第一信令中只需要包括本载波内组对应的NFI和T-DAI,其开销也较小。
此外,网络设备和终端设备对PUCCH中承载的反馈信息不会存在理解歧义。
