Description

信息传输方法、装置、设备及存储介质 技术领域
本申请涉及移动通信领域,特别涉及一种信息传输方法、装置、设备及存储介质。
背景技术
无线通信系统中,终端设备与网络设备之间可以采用SPS(Semi Persistent Schedule,半静态)方式数据,网络设备为终端设备配置SPS传输参数,终端设备根据网络设备配置的SPS传输参数确定网络设备配置的传输资源,网络设备在传输资源上发送SPS PDSCH(Physical Downlink Shared Channel,物理下行共享信道),终端设备根据接收的SPS PDSCH向网络设备发送对应的反馈信息。
但是,为了防止SPS PDSCH对应的反馈信息被丢弃造成的系统效率降低,允许终端设备会推迟发送反馈信息,但推迟发送反馈信息将会导致PDSCH的时序关系混乱,进而导致推迟发送的反馈信息在未推迟发送的反馈信息之后,与SPS PDSCH对应的反馈信息的传输准确性降低。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
首先,先对本申请涉及的名词进行解释:
SPS PDSCH:
在NR系统中,数据传输方式包括两种:动态传输方式和半持续/半静态传输。动态传输的特征在于每一次数据传输的参数由对应的DCI(Downlink Control Information,下行控制信令)指示。
其中,DCI中包括PDSCH所使用的资源、HARQ进程号等信息。
另外,半持续/半静态传输的特征在于传输资源和传输方式都是半持续/半静态配置的,DCI用于激活/释放对应的SPS传输,若对应的SPS激活,后续传输不再需要发送物理层信令。
网络设备通过高层信令为终端设备预先配置SPS传输参数。
在一些实施例中,该SPS传输参数中包括以下至少一项:
(1)SPS周期。
(2)时域资源。
(3)用于传输反馈信息的PUCCH资源。
在一些实施例中,网络设备为SPS PDSCH配置的用于传输反馈信息的PUCCH格式包括PUCCH格式0或PUCCH格式1。其中,PUCCH格式0或PUCCH格式2承载的反馈信息的比特数目最大为2。
网络设备为终端设备配置SPS传输参数后,通过DCI进行SPS激活,在DCI中会进一步指示SPS传输参数。
在一些实施例中,该SPS传输参数中包括以下至少一项:
(1)频域资源。
(2)反馈时长。
例如,如图1所示,网络设备发送DCI信令进行SRS激活后,在相同时域资源内无动态调度的情况下,网络设备总会发送一个SPS PDSCH,终端设备也会通过PUCCH发送一个与SPS PDSCH对应的反馈信息。
在一些实施例中,若根据预配置的反馈时隙确定的时域资源无法用于传输PUCCH,如PUCCH占有的时域符号为下行符号,则该SPS PDSCH的反馈信息将不会被传输。
PDSCH时序关系:
第一种:
若终端设备接收第一PDSCH后,该第一PDSCH对应的HARQ进程编号为X,当终端未发送第一PDSCH对应的反馈信息之前,终端不期待基站调度一个承载与第一PDSCH承载的编号为X的HARQ进程的第二PDSCH。也即是,如图2所示,在通过PDSCH1传输一个HARQ进程X之后,且该HARQ进程X对应的反馈信息未发送之前,基站不能重复使用与该HARQ进程相同的编号进行数据传输。
第二种:
终端设备在时隙I中接收到PDSCH 1,PDSCH 1对应的反馈信息通过时隙J传输,终端不期待收到起 始符号在PDSCH 1的起始符号之后,且反馈信息在PDSCH 1对应的反馈信息之前的PDSCH 2,例如,如图3所示,调度在后的PDSCH 2的反馈信息不能在PDSCH 1的反馈信息之前传输。
下面,对本申请的应用场景进行说明:
图4示出了本申请一个示例性实施例提供的通信系统的框图,该通信系统可以包括:接入网12和终端设备13。
接入网12中包括若干个网络设备120。网络设备120可以是基站,所述基站是一种部署在接入网中用以为终端设备提供无线通信功能的装置。基站可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在LTE系统中,称为eNodeB或者eNB;在5G NR-U系统中,称为gNodeB或者gNB。随着通信技术的演进,“基站”这一描述可能会变化。为方便本申请实施例中,上述为终端设备13提供无线通信功能的装置统称为接入网设备。
终端设备13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备,移动台(Mobile Station,MS),终端设备(terminal device)等等。为方便描述,上面提到的设备统称为终端设备。接入网设备120与终端设备13之间通过某种空口技术互相通信,例如Uu接口。
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、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。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type Communication,MTC),车辆间(Vehicle to Vehicle,V2V)通信以及车联网(Vehicle to everything,V2X)系统等。本申请实施例也可以应用于这些通信系统。
图5示出了本申请一个示例性实施例提供的信息传输方法的流程图,应用于如图4所示的终端设备和网络设备中,该方法包括以下内容中的至少部分内容:
510、终端设备确定与第一时域单元关联的至少一个反馈信息。
在本申请实施例中,网络设备会预先为终端设备预先配置用于进行数据传输的SPS PDSCH传输参数,终端设备根据已配置的SPS PDSCH传输参数接收网络设备发送的SPS PDSCH。
其中,该第一时域单元为终端设备获取的预先配置的多个时域单元中的一个。至少一个反馈信息中包括未推迟反馈信息和推迟反馈信息。
在一些实施例中,该反馈信息包括ACK(Acknowledgement,肯定应答)信息或NACK(Negative Acknowledgement,否定应答)信息。该ACK信息用于指示终端设备确认接收到SPS PDSCH。该NACK信息用于指示终端设备确认未接收到SPS PDSCH。
该未推迟反馈信息包括第一SPS PDSCH对应的反馈信息,第一时域单元为根据反馈时长确定的用于传输第一SPS PDSCH对应的反馈信息的时域单元。该推迟反馈信息包括在第二时域单元内未成功传输的反馈信息,在第二时域单元内未成功传输的反馈信息为第二SPS PDSCH对应的反馈信息,第二时域单元为根据反馈时长确定的用于传输第二SPS PDSCH对应的反馈信息的时域单元。
该反馈时长为终端设备接收到SPS PDSCH后,发送该SPS PDSCH对应的反馈信息的时长。例如,若该反馈时长为1个时隙,终端设备在第一个时隙接收SPS PDSCH,在第二个时隙发送该SPS PDSCH对应的反馈信息。而若该反馈时长为2个时隙,终端设备在第一个时隙接收SPS PDSCH,在第三个时隙发送该SPS PDSCH对应的反馈信息。
另外,该第一时域单元关联的至少一个反馈信息中包括第二时域单元内未成功传输的反馈信息,说明该第二时域单元位于第一时域单元之前。
在一些实施例中,该第一时域单元为时隙,或者该第一时域单元为子时隙,或者,该第一时域单元为至少一个时域符号,本申请实施例并不对第一时域单元进行限定。
在一些实施例中,终端设备确定位于第一时域单元之前,且与第一时域单元相隔反馈时长的倍数的至少一个第二时域单元,将至少一个第二时域单元上未成功传输的反馈信息确定为与第一时域单元关联的反馈信息。
例如,以第一时域单元为时隙为例进行说明。若该第一时域单元为时隙4,且反馈时长为1个时隙,该第一时域单元之前的时域单元分别为时隙1、时隙2、时隙3,该时隙1与时隙4相隔反馈时长的2倍,时隙2与时隙4相隔反馈时长的1倍,时隙3与时隙4相隔反馈时长的0倍,再将时隙1、时隙2和时隙3上未成功传输的反馈信息确定为与该第一时域单元关联的反馈信息。
在另一些实施例中,终端设备确定的用于传输第二SPS PDSCH的时域单元在第一时域单元之前,且与第一时域单元的相隔时域长度不大于最大延迟长度。
本申请实施例中设置有最大延迟长度,该最大延迟长度用于控制SPS PDSCH对应的反馈信息能够延迟传输的时长。例如,若该最大延迟长度为3个时隙,反馈时长为1个时隙,终端设备在第一个时隙接收SPS PDSCH,则该SPS PDSCH对应的反馈信息最迟在第5个时隙传输,若超过第5个时隙,该反馈信息不会再进行传输。
例如,以第一时域单元为时隙为例进行说明。若该第一时域单元为时隙4,且反馈时长为1个时隙,该第一时域单元之前的时域单元分别为时隙1、时隙2、时隙3,该时隙1与时隙4相隔反馈时长的2倍,时隙2与时隙4相隔反馈时长的1倍,时隙3与时隙4相隔反馈时长的0倍,再将时隙1、时隙2和时隙3上未成功传输的反馈信息确定为与该第一时域单元关联的反馈信息。
520、终端设备根据至少一个反馈信息,确定至少一个PUCCH资源。
在本申请实施例中,终端设备确定与第一时域单元关联的至少一个反馈信息,再根据至少一个反馈信息的比特数目确定满足要求的至少一个PUCCH资源。
其中,网络设备为终端设备预先配置用于传输信息的PUCCH资源。例如,终端设备在一个时隙内获取到两个PUCCH资源,两个PUCCH资源分别为第一PUCCH资源和第二PUCCH资源,该第一PUCCH资源和第二PUCCH资源均由网络设备配置。
在一些实施例中,网络设备为终端设备预配置的PUCCH资源承载的比特数目不同。例如,若网络设备为终端设备配置两个PUCCH资源,分别为第一PUCCH资源和第二PUCCH资源,第一PUCCH资源最多承载2比特的反馈信息,第二PUCCH资源承载2比特以上的反馈信息。或者,PUCCH资源还能承载其他比特数目的信息,本申请实施例并不对网络设备为终端设备配置的PUCCH资源进行限定。
在一些实施例中,终端设备根据至少一个反馈信息包括的推迟反馈信息和未推迟反馈信息的总比特数目确定至少一个PUCCH资源。
在本申请实施例中,终端设备根据推迟反馈信息和未推迟反馈信息的总比特数目与PUCCH资源可承载的比特数目的大小来确定PUCCH资源。
例如,若推迟反馈信息和未推迟反馈信息的总比特数目为6比特,PUCCH资源可承载的最大比特数目为8比特,说明该PUCCH资源可承载的比特数目大于推迟反馈信息和未推迟反馈信息的总比特数目,可以承载这些反馈信息。
又例如,若推迟反馈信息和未推迟反馈信息的总比特数目为6比特,而PUCCH资源可承载的最大比特数目为2比特,说明该PUCCH资源可承载的比特数目小于推迟反馈信息和未推迟反馈信息的总比特数目,无法承载这些反馈信息。
在一些实施例中,终端设备根据至少一个反馈信息包括的未推迟反馈信息的比特数目确定至少一个PUCCH资源。
在本申请实施例中,终端设备根据未推迟反馈信息的比特数目与PUCCH资源可承载的比特数目的大小来确定PUCHH资源。
例如,若未推迟反馈信息的比特数目为1比特,PUCCH资源可承载的最大比特数目为2比特,说明该PUCCH资源可承载的比特数目大于未推迟反馈信息的总比特数目,可以承载未推迟反馈信息。
又例如,若未推迟反馈信息的比特数目为4比特,PUCCH资源可承载的最大比特数目为2比特,说明该PUCCH资源可承载的比特数目小于未推迟反馈信息的总比特数目,不可以承载未推迟反馈信息。
530、终端设备根据至少一个PUCCH资源,确定在第一时域单元内发送的反馈信息。
在本申请实施例中,终端设备确定可承载反馈信息的PUCCH资源后,还需要根据PUCCH资源是否可用来确定在第一时域单元内传输的反馈信息。
在一些实施例中,若终端设备根据至少一个反馈信息包括的推迟反馈信息和未推迟反馈信息的总比特数目确定第一PUCCH资源,且该第一PUCCH资源可用,终端设备确定在第一时域单元内发送的反馈信息中包括推迟反馈信息和未推迟反馈信息。
在另一些实施例中,终端设备根据至少一个反馈信息包括的推迟反馈信息和未推迟反馈信息的总比特数目确定第一PUCCH资源,根据未推迟反馈信息的比特数目确定第二PUCCH资源,且该第一PUCCH 资源不可用,第二PUCCH资源可用,终端设备确定在第一时域单元内发送的反馈信息中包括未推迟反馈信息。
其中,若终端设备确定在第一时域单元内发送的反馈信息中包括未推迟反馈信息,则终端设备清除至少一个反馈信息中的推迟反馈信息。
在一些实施例中,终端设备清除至少一个反馈信息中的推迟反馈信息还可以替换为以下任一项:
(1)终端设备丢弃至少一个反馈信息中的推迟反馈信息。
(2)终端设备取消至少一个反馈信息中的推迟反馈信息。
(3)终端设备跳过至少一个反馈信息中的推迟反馈信息。
(4)终端设备不存储至少一个反馈信息中的推迟反馈信息。
例如,如图6所示,以时域单元为时隙为例进行说明。时隙n中的SPS PDSCH 0和SPS PDSCH 1的反馈信息在时隙n+1中传输,但该时隙为下行时隙,无法传输反馈信息,则对应的反馈信息需要进行推迟。时隙n+1中的SPS PDSCH 2和SPS PDSCH 3的反馈信息在时隙n+2中传输,但该时隙为下行时隙,无法传输反馈信息,则对应的反馈信息需要进行推迟。时隙n+2中的SPS PDSCH 4和SPS PDSCH 5的反馈信息在时隙n+3中传输。若在时隙n+3中只传输SPS PDSCH 4和SPS PDSCH 5对应的2比特反馈信息,使用PUCCH资源1,PUCCH资源1占有的时域符号都是上行符号,即PUCCH资源1可用。但在时隙n+3中传输SPS PDSCH 0~5对应的6比特反馈信息,需要使用PUCCH资源2,但PUCCH资源2占有的时域符号包括下行符号,即PUCCH资源2不可用,因此,终端设备确定SPS PDSCH 4和SPS PDSCH 5对应的2比特反馈信息在时隙n+3中传输,清除SPS PDSCH 0~3的反馈信息。
需要说明的是,本申请实施例仅是以PUCCH资源是否可用为例进行说明。在另一实施例中,将对如何判断PUCCH资源是否不可用进行说明。
在一些实施例中,PUCCH资源不可用包括:
PUCCH资源占有的时域符号包括如下情况中的至少一种:
(1)下行时域符号。
(2)灵活时域符号。
(3)广播信道占用的时域符号。
(4)同步信道占用的时域符号。
(5)下行参考符号占用的时域符号。
(6)控制信道占用的时域符号。
(7)网络设备预配置的时域符号。
其中,若PUCCH资源中的时域符号包括以下至少一种时域符号,则说明该PUCCH资源中的时域符号无法进行上行传输,说明该PUCCH资源不可用。
在另一些实施例中,PUCCH资源可用与PUCCH资源不可用为相反的条件,若终端设备确定PUCCH资源不符合不可用的条件,则确定该PUCCH资源可用。
在另一些实施例中,终端设备还可以根据PUCCH资源中是否包括以下时域符号来确定PUCCH资源是否可用:
(1)PUCCH资源占用的时域符号为上行符号。
(2)PUCCH资源占用的时域符号不包括下行符号、广播信道占用的时域符号、同步信道占用的时域符号。
若终端设备确定PUCCH资源占用的时域符号为上述两种情况中的任一种,则说明PUCCH资源为可用资源。
需要说明的是,本申请实施例仅是以从至少一个反馈信息中确定在第一时域单元内发送的反馈信息为例进行说明。而在另一实施例中,终端设备获取的时域单元关联的至少一个反馈信息中包括多个SPS PDSCH对应的反馈信息,且多个SPS PDSCH承载的HARQ进程不同。
其中,终端设备控制多个SPS PDSCH承载的HARQ进程不同的方式请参见下述图7所示的方法。
本申请实施例提供了一种信息传输方法,根据第一时域单元关联的反馈信息确定满足要求的PUCCH资源,且从至少一个反馈信息中,根据PUCCH资源确定能够在第一时域单元内发送的反馈信息,确保发送的反馈信息满足传输需求,而剩余反馈信息无需传输,保证推迟反馈信息不会影响PDSCH的时序关系,提高反馈信息的发送准确性,也提高了反馈信息的传输稳定性。
图5实施例对终端设备如何根据至少一个反馈信息及PUCCH资源确定反馈信息为例进行说明。而在另一实施例中,若终端设备确定的目标信息为空,终端设备还会根据位于第一时域单元之后的第三时域单元确定反馈信息,具体参见图7实施例:
710、若终端设备确定在第一时域单元内发送的反馈信息为空,确定与第三时域单元关联的至少一个 反馈信息。
在本申请实施例中,终端设备通过上述步骤510-530确定的在第一时域单元内发送的反馈信息为空,说明此时的第一时域单元仍无法传输反馈信息,终端设备需要根据第一时域单元之后的第三时域单元获取与该第三时域单元关联的至少一个反馈信息。
在一些实施例中,若终端设备根据至少一个反馈信息包括的推迟反馈信息和未推迟反馈信息的总比特数目确定第一PUCCH资源,且该第一PUCCH资源不可用,终端设备确定在第一时域单元内发送的反馈信息为空。
在另一些实施例中,终端设备根据至少一个反馈信息包括的推迟反馈信息和未推迟反馈信息的总比特数目确定第一PUCCH资源,根据未推迟反馈信息的比特数目确定第二PUCCH资源,且该第一PUCCH资源不可用,第二PUCCH资源不可用,终端设备确定在第一时域单元内发送的反馈信息为空。
其中,终端设备确定与第三时域单元关联的至少一个反馈信息的过程与步骤510类似,在此不再赘述。
720、终端设备根据至少一个反馈信息,确定至少一个PUCCH资源。
730、终端设备根据至少一个PUCCH资源,确定在第一时域单元内发送的反馈信息。
其中,步骤720-730与上述步骤520-530类似,在此不再赘述。
需要说明的是,本申请实施例仅是以在反馈信息为空的情况下,根据第三时域单元确定反馈信息为例进行说明。在另一些实施例中,若在第一时域单元内发送的反馈信息为空时,先确定位于第一时域单元之后的第三时域单元是否包括PUCCH资源,若不包括PUCCH资源,获取位于第三时域单元之后的第四时域单元,继续判断第四时域单元是否包括PUCCH资源,直至确定时域单元包括PUCCH资源的情况下,执行步骤710。
例如,结合图6对本申请实施例的步骤进行说明。若终端设备确定的第一时域单元为时隙n,该时隙n为下行时隙,不包括PUCCH资源,跳过该时隙n。终端设备再确定时隙n+1关联的反馈信息,且该时隙n+1为下行时隙,不包括PUCCH资源,跳过时隙n+1。终端设备再确定时隙n+2关联的反馈信息,且该时隙n+2为下行时隙,不包括PUCCH资源,跳过时隙n+2。终端设备再确定时隙n+3关联的反馈信息包括SPS PDSCH 0-5对应的反馈信息,比特数目为6,终端设备确定PUCCH资源2,且PUCCH资源2占有的部分符号为下行符号,说明该PUCCH资源不可用,因为终端设备确定在时隙n+3内发送的反馈信息为空。终端设备再确定时隙n+4关联的反馈信息,且该时隙n+4为下行时隙,不包括PUCCH资源,则终端设备确定在时隙n+4内发送的反馈信息为空,跳过时隙n+4。终端设备再确定时隙n+5关联的反馈信息包括SPS PDSCH 4-8对应的反馈信息,且比特数目为5,确定PUCCH资源2,且PUCCH资源2占有的符号都为上行符号,因此终端设备确定PUCCH资源2可用,SPS PDSCH 4-8的反馈信息在slot n+5中发送。
本申请实施例提供的方法,终端设备先确定位于第一时域单元之后的时域单元是否包括PUCCH资源,若不包括直接跳过该时域单元,继续确定下一个时域单元是否包括PUCCH资源,能够提高终端设备的执行效率。
需要说明的是,上述举例仅是从时域单元的角度进行说明。而在另一实施例中,还可以从SPS PDSCH的角度进行说明。
例如,以最大反馈延迟长度为2个时隙为例,结合图6为例进行说明。终端设备接收的第一SPS PDSCH的时隙为时隙n+2,则第一SPS PDSCH对应的反馈信息需要在时隙n+3传输,此时终端设备确定的第一时域单元为时隙n+3,且时隙n+3关联的反馈信息包括SPS PDSCH 0-5对应的反馈信息,比特数目为6,终端设备确定PUCCH资源2,且PUCCH资源2中包括下行符号,说明该PUCCH资源2不可用,因此终端设备确定在时隙n+3内发送的反馈信息为空。终端设备再确定下一个时隙n+4,且该时隙n+4不包括PUCCH资源,说明该时隙n+4无法发送反馈信息,跳过该时隙n+4。终端设备再确定时隙n+5关联的反馈信息包括SPS PDSCH 4-8对应的反馈信息,比特数目为5,确定PUCCH资源2,且PUCCH资源2占有的符号都为上行符号,因此终端设备确定PUCCH资源2可用,SPS PDSCH 0-3的反馈信息不再传输,而SPS PDSCH 4-8的反馈信息在slot n+5中传输。
本申请实施例提供的方法,若在第一时域单元内发送的反馈信息为空的情况下,终端设备会根据下一个时域单元关联的反馈信息继续确定满足要求的PUCCH资源,且从至少一个反馈信息中,根据PUCCH资源确定能够在第一时域单元内传输的反馈信息,确保传输的反馈信息满足传输需求,而剩余反馈信息无需传输,保证能够传输SPS PDSCH对应的反馈信息,防止出现反馈信息无法传输的情况,并且也不会因为推迟反馈信息影响PDSCH的时序关系,提高反馈信息的发送准确性,也提高了反馈信息的传输稳定性。
需要说明的是,图5和图7实施例仅是以终端设备如何确定在第一时域单元内发送的反馈信息为例进行说明。而在另一实施例中,网络设备也会根据第一时域单元关联的至少一个反馈信息,确定在第一时域单元内接收的反馈信息,具体方法请参见图8,该方法包括:
810、网络设备确定与第一时域单元关联的至少一个反馈信息。
其中,至少一个反馈信息中包括未推迟反馈信息和推迟反馈信息,未推迟反馈信息包括第一SPS PDSCH对应的反馈信息,第一时域单元为根据反馈时长确定的用于传输第一SPS PDSCH对应的反馈信息的时域单元,推迟反馈信息包括在第二时域单元内未成功传输的反馈信息,在第二时域单元内未成功传输的反馈信息为第二SPS PDSCH对应的反馈信息,第二时域单元为根据反馈时长确定的用于传输第二SPS PDSCH对应的反馈信息的时域单元,第二时域单元位于第一时域单元之前。
在一些实施例中,用于传输第二SPS PDSCH的时域单元在第一时域单元之前,且与第一时域单元之间的相隔时域长度不大于最大延迟长度。
在一些实施例中,至少一个反馈信息中包括多个SPS PDSCH对应的反馈信息,多个SPS PDSCH承载的HARQ进程不同。
其中,第一时域单元为时隙,或者,第一时域单元为子时隙,或者,第一时域单元为至少一个时域符号。
820、网络设备根据至少一个反馈信息,确定至少一个PUCCH资源。
其中,步骤810-820的过程与上述步骤510-520类似,在此不再赘述。
830、网络设备根据至少一个PUCCH资源,确定在第一时域单元内接收的反馈信息。
在一些实施例中,至少一个PUCCH资源包括第一PUCCH资源,第一PUCCH资源根据未推迟反馈信息和推迟反馈信息的总比特数目确定。
其中,根据至少一个PUCCH资源,确定在第一时域单元内接收的反馈信息,包括:若第一PUCCH资源可用,在第一时域单元内接收的反馈信息包括未推迟反馈信息和推迟反馈信息。
在另一些实施例中,至少一个PUCCH资源包括第一PUCCH资源和第二PUCCH资源,第一PUCCH资源根据未推迟反馈信息和推迟反馈信息的总比特数目确定,第二PUCCH资源根据未推迟反馈信息的比特数目确定。
其中,根据至少一个PUCCH资源,确定在第一时域单元内接收的反馈信息,包括:若第一PUCCH资源不可用,第二PUCCH资源可用,在第一时域单元内接收的反馈信息包括未推迟反馈信息。
需要说明的是,本申请实施例仅是以网络设备确定在第一时域单元内接收的反馈信息不为空为例进行说明。在另一实施例中,若在第一时域单元内发送的反馈信息为空,确定与第三时域单元关联的至少一个反馈信息。其中,第三时域单元位于第一时域单元之后。
在一些实施例中,至少一个PUCCH资源包括第一PUCCH资源,且第一PUCCH资源不可用;其中,第一PUCCH资源根据未推迟反馈信息和推迟反馈信息的总比特数目确定。
在另一些实施例中,至少一个PUCCH资源包括第一PUCCH资源和第二PUCCH资源,且第一PUCCH资源不可用;其中,第一PUCCH资源根据未推迟反馈信息和推迟反馈信息的总比特数目确定,第二PUCCH资源根据未推迟反馈信息的比特数目确定。
在一些实施例中,PUCCH资源不可用包括:
PUCCH资源占有的时域符号包括如下情况中的至少一种:
下行时域符号;
灵活时域符号;
广播信道占用的时域符号;
同步信道占用的时域符号;

网络设备预配置的时域符号。
其中,步骤830的过程与上述步骤530、步骤710-730的过程类似,在此不再赘述。
需要说明的是,本申请中的图8实施例可以与上述图5或图7实施例相结合,本申请不作限定。
本申请实施例提供了一种信息传输方法,根据第一时域单元关联的反馈信息确定满足要求的PUCCH资源,且从至少一个反馈信息中,根据PUCCH资源确定能够在第一时域单元内传输的反馈信息,确保传输的反馈信息满足传输需求,而剩余反馈信息无需传输,保证推迟反馈信息不会影响PDSCH的时序关系,提高反馈信息的发送准确性,也提高了反馈信息的传输稳定性。
图9示出了本申请一个示例性实施例提供的信息传输方法的流程图,应用于如图4所示的终端设备中,该方法包括以下内容中的至少部分内容:
910、终端设备通过第一时域单元接收第一SPS PDSCH。
第一SPS PDSCH承载第一HARQ进程,第一SPS PDSCH对应的反馈信息通过第二时域单元传输。该第二时域单元为第一SPS PDSCH对应的反馈信息推迟传输后的时域单元,或者,为第一SPS PDSCH对 应的反馈信息未推迟传输的时域单元。
在本申请实施例中,网络设备通过第一时域单元向终端设备发送第一SPS若PDSCH,则终端设备通过第一时域单元接收第一SPS PDSCH。
920、若位于第二时域单元之前的时域单元中包括第三时域单元,且第二SPS PDSCH承载第一HARQ进程,对第一SPS PDSCH对应的反馈信息或第二SPS PDSCH进行失效处理。
其中,第三时域单元用于传输第二SPS PDSCH。
在本申请实施例中,若终端设备在第一时域单元接收到第一SPS PDSCH,且发送该第一SPS PDSCH对应的反馈信息的时域单元为第二时域单元,则在该第二时域单元之前,若存在与第一SPS PDSCH承载的HARQ进程相同的第二SPS PDSCH,则终端设备为了防止发生时序混乱问题,对第一SPS PDSCH对应的反馈信息或第二SPS PDSCH进行失效处理。
在一些实施例中,终端设备对第一SPS PDSCH对应的反馈信息,包括:清除第一SPS PDSCH对应的反馈信息。
其中,终端设备清除第一SPS PDSCH对应的反馈信息还可以替换为以下任一项:
(1)终端设备丢弃第一SPS PDSCH对应的反馈信息。
(2)终端设备取消第一SPS PDSCH对应的反馈信息。
(3)终端设备跳过第一SPS PDSCH对应的反馈信息。
(4)终端设备不存储第一SPS PDSCH对应的反馈信息。
例如,如图10所示,在时隙n-n+3中的每个时隙内配置了2个SPS PDSCH,时隙n内的两个SPS PDSCH分别承载HARQ进程0和HARQ进程7,时隙n+1内的两个SPS PDSCH分别承载HARQ进程1和HARQ进程8,时隙n+2内的两个SPS PDSCH分别承载HARQ进程2和HARQ进程0,时隙n+3内的两个SPS PDSCH分别承载HARQ进程3和HARQ进程1。若终端设备在时隙n中接收的第一SPS PDSCH承载HARQ进程0,且该第一SPS PDSCH在时隙n+4内传输,而在时隙n+2内存在第二SPS PDSCH承载HARQ进程0,则终端设备需要对第一SPS PDSCH对应的反馈信息或第二SPS PDSCH进行失效处理。
在另一些实施例中,终端设备对第二SPS PDSCH进行失效处理包括:终端设备不会在第三时域单元上接收第二SPS PDSCH。
在另一些实施例中,若终端设备在所述第二时域单元之前,接收动态调度PDSCH,且所述动态调度PDSCH承载第二HARQ进程,则终端设备根据接收的动态调度PDSCH传输对应的反馈信息,无需再执行步骤920。
本申请实施例提供的方法,终端设备会根据在第一时域单元内已接收的SPS PDSCH确定传输对应的反馈信息的第二时域单元,并且若存在位于第二时域单元之前,且与SPS PDSCH承载相同HARQ进程的第三时域单元,而此时在第一时域单元接收的SPS PDSCH对应的反馈信息未传输完成,无法接收第二个承载相同HARQ进程的SPS PDSCH,则对第一SPS PDSCH对应的反馈信息或第二SPS PDSCH进行失效处理,防止由于承载相同的HARQ进程而导致出现PDSCH时序混乱的问题,提高反馈信息的发送准确性,也提高了反馈信息的传输稳定性。
图9实施例说明了终端设备如何对SPS PDSCH对应的反馈信息或第二SPS PDSCH进行失效处理的过程,而网络设备同样也会确定终端设备如何对SPS PDSCH对应的反馈信息或第二SPS PDSCH进行失效处理,进而判断如何执行后续过程,下面图11示出了本申请一个示例性实施例提供的信息传输方法的流程图,参见图11,该方法包括:
1110、网络设备通过第一时域单元发送第一SPS PDSCH。
其中,第一SPS PDSCH承载第一HARQ进程,第一SPS PDSCH对应的反馈信息通过第二时域单元传输。
步骤1110的过程与上述步骤910类似,在此不再赘述。
1120、若位于第二时域单元之前的时域单元中包括第三时域单元,且第三时域单元用于传输第二SPS PDSCH,网络设备确定第一SPS PDSCH对应的反馈信息或第二SPS PDSCH失效。
其中,第二SPS PDSCH承载第一HARQ进程。
在本申请实施例中,若网络设备在第一时域单元发送第一SPS PDSCH,且接收该第一SPS PDSCH对应的反馈信息的时域单元为第二时域单元,则在该第二时域单元之前,若存在与第一SPS PDSCH承载的HARQ进程相同的第二SPS PDSCH,则终端设备和网络设备为了防止发生时序混乱问题,终端设备对第一SPS PDSCH对应的反馈信息或第二SPS PDSCH进行失效处理,网络设备需要确定终端设备做了失效处理的反馈信息或SPS PDSCH。
在另一些实施例中,网络设备确定第二SPS PDSCH失效包括:网络设备不会在第三时域单元上发送第二SPS PDSCH。
需要说明的是,终端设备对第一SPS PDSCH对应的反馈信息进行失效处理后,终端设备在第二时域单元内发送除已失效处理后的其他反馈信息,网络设备在第二时域单元内接收终端设备发送的反馈信息。
在另一些实施例中,若网络设备在所述第二时域单元之前,发送动态调度PDSCH,且所述动态调度PDSCH承载第二HARQ进程,则网络设备根据接收的动态调度PDSCH接收对应的反馈信息,无需再执行步骤1120。
本申请实施例提供的方法,网络设备会根据在第一时域单元内发送的SPS PDSCH确定传输对应的反馈信息的第二时域单元,并且若存在位于第二时域单元之前,且与SPS PDSCH承载相同HARQ进程的第三时域单元,而此时在第一时域单元接收的SPS PDSCH对应的反馈信息未传输完成,无法接收第二个承载相同HARQ进程的SPS PDSCH,确定第一SPS PDSCH对应的反馈信息或第二SPS PDSCH失效,防止由于承载相同的HARQ进程而导致出现PDSCH时序混乱的问题,提高反馈信息的发送准确性,也提高了反馈信息的传输稳定性。
