It uses the principle of division and remainder for error detection. Specifically, the CRC forms an n-bit transmission frame T by adding (n-k) redundant bits, that is, a frame check sequence (Frame Check Sequence, FCS), after the k-bit data D to be transmitted. Rate matching means that the bits on the transmission channel are repeated, zero-filled or punctured to match the carrying capacity of the physical channel, and the bit rate required by the transmission format is reached during channel mapping.

Description

无线通信方法、第一设备和第二设备 技术领域
本申请实施例涉及通信领域,并且更具体地,涉及一种无线通信方法、第一设备和第二设备。
背景技术
截止目前,物理上行共享信道(Physical Uplink Shared Channel,PUSCH)重复传输的重复次数是半静态配置的,当和灵活时隙结构同时使用时,会导致部分时隙(slot)的PUSCH重复被忽略掉(或被取消)。也就是说,在一些配置,尤其是时分双工(Time Division Duplexing,TDD)的情况下,配置的重复次数不能达到理想的覆盖增强效果。
对于物理上行数据信道增强(PUSCH)的方案,通常分为基于Type B的PUSCH重复传输和基于Type A的PUSCH重复传输。针对基于Type A的PUSCH重复传输,终端基于第n次传输时机(n th transmission occasion)确定其对应的冗余版本(redundancy version,RV),此时如果由于突发情况(例如发送PRACH),RV0对应的PUSCH传输被取消(cancel),会导致译码性能恶化。例如,假设一个传输时机为一个时隙,则终端设备在向网络设备发送多个PUSCH重复的过程中,针对该多个PUSCH重复中的某一个PUSCH重复,需要基于用于发送该某一个PUSCH重复的时隙的时域位置,确定其对应的冗余版本(redundancy version,RV)的版本号,如果在用于发送该某一个PUSCH重复的时隙被取消,即其RV对应的PUSCH重复被取消,如果被取消的PUSCH重复为RV0对应的PUSCH重复,会导致译码性能恶化。此外,针对基于Type B的PUSCH重复传输,终端基于实际重复(actual repetition)的次数确定其对应的RV,如果存在被取消的PUSCH重复,其后续实际重复对应的RV会发生变化,但是网络侧并不知道,这将会导致PUSCH重复传输中网络侧和UE对PUSCH对应的RV版本的理解存在不一致的问题。

图1是本申请实施例的一个系统框架的示意图。
如图1所示,通信系统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系统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系统,例如:长期演进(Long Term Evolution,LTE)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile  Telecommunication System,UMTS)、物联网(Internet of Things,IoT)系统、窄带物联网(Narrow Band Internet of Things,NB-IoT)系统、增强的机器类型通信(enhanced Machine-Type Communications,eMTC)系统、5G通信系统(也称为新无线(New Radio,NR)通信系统),或未来的通信系统等。

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、IoT设备、卫星手持终端、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。

为了增强上行传输的可靠性,NR R15引入了时隙聚合PUSCH重复传输。时隙聚合PUSCH重复传输是指同一个传输块采用不同的冗余版本重复传输K次。基站通过高层参数,即PUSCH聚合因子 (pusch-AggregationFactor),为终端配置重复次数K,终端在K个连续的时隙上重复发送相同传输块,且每个时隙中承载该传输块的PUSCH副本在时域上占用相同的符号。第一个PUSCH副本的冗余版本(RV)是由上行授权信令指示的,其余PUSCH副本的RV是以{0,2,3,1}为顺序循环的。下面结合表1对RV的的传输情况进行说明。
表1
Figure PCTCN2021093465-appb-000001
如表1所示,终端可通过循环缓存对传输块实现速率匹配。即,终端可将编码比特存储在循环缓存中,每次传输时根据冗余版本从循环缓存中顺序读取,实现速率匹配。换言之,对于每次传输,速率匹配的读取位置由冗余版本rv决定,或者说,RV版本可用于指示从这个缓冲区的哪个位置来提取数据。作为示例,假设循环缓存中预先设置有4个RV,分别为RV 0、RV 1、RV 2和RV 3。这4个RV的选取顺序为[0,2,3,1],即经第一次传输以RV 0为起始位置,第二次传输以RV 2为起始位置,第三次传输以RV 3为起始位置,第四次传输以RV 1为起始位置,其中,第一次传输是指数据的首次传输,第二、三、四次传输均为数据的重传。0、2、3、1是LTE/NR传输数据时RV典型的选取顺序,其中,0、2、3、1分别为第一个RV(即RV 0)对应的取值、第三个RV(即RV 2)对应的取值、第四个RV(即RV 3)对应的取值和第二个RV(即RV 1)对应的取值。
如果一个时隙中的PUSCH副本对应的时域资源中至少有一个半静态下行符号,那么这个时隙中的PUSCH不发送。
图2是本申请实施例提供的时隙聚合PUSCH重复传输的示意图。
如图2所示,基站配置终端将传输块重复发送4次,PUSCH副本在每个时隙中占用的都是#0~#11符号。但是,由于时隙#1和时隙#2的#0~#2符号是半静态下行符号,因此,在时隙#1上待发送的第2个PUSCH重复和时隙#2上待发送的第3个PUSCH重复会被丢弃而不进行发送。
对于上行免授权调度的时隙聚合PUSCH重复,传输块的重复次数由高层参数RepK配置。
对于物理上行数据信道增强(PUSCH)的方案,分为基于Type B的PUSCH重复传输和基于Type A的PUSCH重复传输。
其中,针对基于Type B的PUSCH重复传输,基站发送一个上行授权或者一个免授权指示一个或多个名义PUSCH重复传输。终端在一个时隙中传输一个或多个实际PUSCH副本,或者在连续多个可用的时隙中传输两个或多个实际PUSCH副本。基站在时域资源分配表(Time Domain Resource Allocation,TDRA)中增加一列,用于指示B类PUSCH重复传输的副本个数numberofrepetition,其取值可以为{1,2,3,4,7,8,12,16}。上行调度信令或者第一类免授权配置信息指示第一个名义PUSCH的起始符号S和持续时间L,每一个名义PUSCH副本的持续时间L相同,其中,0≤S≤13,1≤L≤14,高层信令各用4bit分别指示S和L,可以实现S+L>14。名义和实际PUSCH副本的传输块大小(TBS)根据名义PUSCH的时域长度L确定。从第二个名义PUSCH开始,名义PUSCH副本的起始符号是上一个名义PUSCH副本的终止符号的下一个符号。
终端在确定实际PUSCH副本的时域资源之前,需要确定无效符号,其余的符号可以认为是潜在有效符号。如果一个名义PUSCH副本在时隙内连续潜在有效符号的个数大于0,则可以映射一个实际PUSCH副本,一个名义PUSCH副本的时域资源可包含一个或多个实际PUSCH副本的时域资源。终端不发送单个符号的实际PUSCH副本,除非单个符号是基站指示的名义PUSCH的持续时间L。
图3是本申请实施例提供的基于Type B的PUSCH重复传输的时域资源示意图。
如图3所示,基站发送一个上行授权或者一个免授权指示4个名义PUSCH重复传输,每一个名义PUSCH副本的持续时间L等于4。第1个名义PUSCH副本的时域资源可包含2个实际PUSCH副本(即第1个实际PUSCH和第2个实际PUSCH)的时域资源,第2个名义PUSCH副本的时域资源可包含1个实际PUSCH副本(即第3个实际PUSCH)的时域资源,第3个名义PUSCH副本的时域资源可包含2个实际PUSCH副本(即第4个实际PUSCH和第5个实际PUSCH)的时域资源,第4个名义PUSCH副本的时域资源可包含2个实际PUSCH副本的时域资源;但是,由于位置靠前的实际PUSCH副本的时域资源为一个符号,不发送该实际PUSCH副本,即仅发送位置靠后的实际PUSCH副本(即第6个实际PUSCH)。
在一些实现方式中,终端可按照以下方式中的至少一项确定无效符号:
方式1:
高层参数tdd-UL-DL-ConfigurationCommon或tdd-UL-DL-Configuration Dedicated半静态配置的下行符号是一种无效符号。
方式2:
高层参数InvalidSymbolPattern配置符号级位图(Bitmap),比特值为1表示相应的符号为无效符号。当DCI格式0_1或者0_2调度PUSCH重复,或者激活第二类免授权PUSCH重复,而且DCI中配置了1Bit的无效符号图样指示信息域,当无效符号图样指示信息域为1时,终端应用无效符号图样,否则终端忽略无效符号图样。如果DCI中不包含无效符号图样指示信息域,终端直接按照高层参数InvalidSymbolPattern的配置应用无效符号图样。不同的DCI格式独立配置无效符号图样指示信息域。
对于基于Type A的PUSCH重复传输,基站可以在高层信令配置的时域资源分配表格中增加一列numberofrepetitions,用于指示A类PUSCH重复传输次数K。如果没有配置numberofrepetitions,重复次数K由高层参数pusch-AggregationFactor确定。如果前述两个参数都没有配置,重复次数K=1。基于Type A的PUSCH重复传输是用户在连续的K个时隙上发送同一个传输块(TB),且在K个时隙中占据的符号位置完全相同(起始符号位置与占据符号长度均相同)。与HARQ相似的地方在于,二者都可以看做是信息的重传;其不同点在于,HARQ需要收到NACK才会触发重传,而PUSCH重复配置结束以后可以直接进行K次重传。第一次传输的版本号可根据下行控制信息(Downlink Control Information,DCI)域(field)中的指示信息确定,所述指示信息可占据两个比特位,之后的RV版本号按照0,2,3,1循环。比如,当DCI指示第一次传输的版本号为2,则后面的版本号依次为3,1,0,2,…。
针对免授权PUSCH重复,当高层参数PUSCHRepTypeIndicatorForType1Configuredgrant配置为pusch-RepTypeB,表明为B类PUSCH重复,否则为A类PUSCH重复。如果时域资源分配表格中有numberofrepetitions,PUSCH的名义重复传输次数由TDRA表格中的一行确定,否则重复次数由高层参数repK确定。
通过内容可知,物理上行共享信道(Physical Uplink Shared Channel,PUSCH)重复传输的重复次数是半静态配置的,当和灵活时隙结构同时使用时,会导致部分时隙(slot)的重复被忽略掉。因此,在一些配置,尤其是TDD的情况下,配置的重复次数不能达到理想的覆盖增强效果。
此外,在第三代合作伙伴计划(The 3rd Generation Partnership Project,3GPP)第17版本(R17)中,考虑在PUSCH的重复传输中将引入基于多时隙的传输块过程(TB processing over multi-slot,TBoMS),即基于多个时隙确定传输块大小(Transport Block Size,TBS)的大小,或者说,将一个传输块(Transport Block,TB)在多个时隙上进行传输。然而,针对R15/R16的速率匹配机制,基于Type A的PUSCH重复传输(repetition type A)是在每一个时隙上基于冗余版本(redundancy version,RV)进行速率匹配处理的,如果按照R15/R16的速率匹配机制对TboMS中的传输块进行速率匹配,每一个时隙上基于一个RV进行速率匹配时,由于TBS是针对多个时隙确定的,有可能会丢失RV0和/或RV1对应的系统位,使的译码性能下降。例如,当一个时隙上可用于上行传输的符号不足以传输一个RV对应的比特序列时,可能会丢失RV0和/或RV1对应的系统位,使的译码性能下降。
基于此,本申请实施例提供了一种无线通信方法、终端设备和网络设备,不仅能够实现对TboMS中的传输块的速率匹配,还能够避免丢失RV0和/或RV1对应的系统位,以提升对速率匹配后的序列的译码性能。
为例便于理解本申请提供的方案,下面对LDPC码的编码流程进行简单说明。
在LDPC码的编码流程中,物理层在接收到媒体接入控制层(MAC)的一个传输块之后,先给它添加一个(16或24比特)的循环冗余校验(Cyclic Redundancy Check,CRC)。在添加CRC之后,如果它包含的比特数超过一定值,则需要把它分成长度相同的两个或多个码块;各个码块再各自添加CRC;然后,各个加了CRC的码块独立地进行LDPC编码;再然后,各个编码后的码块分别进行速率匹配、混合自动重传请求(HARQ)处理和交织。其中,CRC是一种根据网络数据包或计算机文件等数据产生简短固定位数校验码的一种信道编码技术,主要用来检测或校验数据传输或者保存后可能出现的错误。它是利用除法及余数的原理来作错误侦测的。具体地,CRC通过在要传输的k比特数据D后添加(n-k)比特冗余位,即帧检验序列(Frame Check Sequence,FCS),以形成n比特的传输帧T。速率匹配(Rate matching)是指传输信道上的比特被重发(repeated)、零填充或者被打孔(punctured),以匹配物理信道的承载能力,信道映射时达到传输格式所要求的比特速率。在速率匹配中,如果输入比特数少于输出比特数,那就是用重发或者零比特填充;如果输入比特数多于输出比特数,那就是用打孔。打孔就是依照一定的图样(pattern)把一些比特打掉,即从比特序列中移除或打掉,同时将后面的比特依次前移一位。重复就是在当前比特和后面的比特之间插入一次当前比特。零比特填充是在 当前比特和后面的比特之间插入零比特。解速率匹配算法与之相反,恢复被打掉的比特,或者打掉重复/零填充的比特。
在速率匹配过程中,可将经过编码的比特序列用d 0,d 1,d 2,...d N-1(N为编码之后的序列长度)来表示,该序列会输入到一个长度为N cb的循环缓存区中。用E r表示第r个码块经过速率匹配后的输出序列的长度。
在一种实现方式中,E r的确定过程可通过以下代码实现:
Figure PCTCN2021093465-appb-000002
其中,N L是传输块要映射的传输层数;Q m是调制阶数;G是传输块用于传输的编码后比特的总数目;如果在调度传输块的DCI中没有出现CBGTI,则C′=C,如果在调度传输块的DCI中出现了CBGTI,则C′是调度传输块的码块的个数。
传输的冗余版本号可表示为rv id,(rv id=0,1,2,or 3),速率匹配后的输出序列用e k表示,k=0,1,2,…,E-1。速率匹配后的输出序列中的第一个比特k 0与rv id和低密度奇偶校验码(Low Density Parity Check Code,LDPC)的基图(Base Graph,BG)有关。其中,BG是整个LDPC码设计的核心。每个TB码块需要通过LDPC基图1(LDPC base graph 1)或者LDPC基图2(LDPC base graph 2)编码。下面结合表2对LDPC基图和rv id的关系进行说明。
表2
Figure PCTCN2021093465-appb-000003
如图2所示,针对标识为0的RV,其对应的LDPC基图1和LDPC基图2均为0,针对标识为1、2或3的RV,其均可对应有一个LDPC基图1和一个LDPC基图2。
在一种实现方式中,经由速率匹配后输出的序列e k的可通过以下代码实现:
Figure PCTCN2021093465-appb-000004
Figure PCTCN2021093465-appb-000005
对速率匹配得到的编码比特进行交织后再调制,即比特交织编码调制,其用于保证LDPC码在高阶调制和衰落信道下的性能稳定性。经过比特选择得到的比特序列为e 0,e 1,e 2,...,e E-1,该比特序列需要进行交织,交织之后得到序列f 0,f 1,f 2,...,f E-1
在一种实现方式中,可通过以下代码实现比特交织:

如表2所示,针对基于Type A的PUSCH重复传输,终端基于第n次传输时机(n th transmission occasion)确定其对应的冗余版本(redundancy version,RV),针对基于Type B的PUSCH重复传输,终端基于实际重复(actual repetition)的次数确定其对应的RV。
针对基于Type A的PUSCH重复传输,由于终端基于第n次传输时机(n th transmission occasion)确定其对应的冗余版本(redundancy version,RV),此时如果由于突发情况(例如发送PRACH),RV0对应的PUSCH传输被取消(cancel),会导致译码性能恶化。例如,假设一个传输时机为一个时隙,则终端设备在向网络设备发送多个PUSCH重复的过程中,针对该多个PUSCH重复中的某一个PUSCH重复,需要基于用于发送该某一个PUSCH重复的时隙的时域位置,确定其对应的冗余版本(redundancy version,RV)的版本号,如果在用于发送该某一个PUSCH重复的时隙被取消,即其RV对应的PUSCH重复被取消,如果被取消的PUSCH重复为RV0对应的PUSCH重复,会导致译码性能恶化。
针对基于Type B的PUSCH重复传输,由于终端基于实际重复(actual repetition)的次数确定其对应的RV,如果存在被取消的PUSCH重复,其后续实际重复对应的RV会发生变化,但是网络侧并不知道,这将会导致PUSCH重复传输中网络侧和UE对PUSCH对应的RV版本的理解存在不一致的问题。
基于此,本申请实施例提供了一种无线通信方法、第一设备和第二设备,能够提升译码性能的基础上,在重复传输中网络侧和终端侧对每一次传输对应的RV版本的理解保持一致,进而提升通信质量。下面对本申请提供的无线通信方法进行说明。
图4示出了根据本申请实施例的无线通信方法200的示意性流程图,所述方法200可以由第一设备执行。该第一设备可以是物理信道重复传输的发送端,例如图1所示的终端设备或网络设备。
如图4所示,所述方法200可包括:
S210,确定第一物理信道的重复传输次数;
S220,基于所述第一物理信道对应的多个可用时域单元进行计数,得到每一个可用时域单元的计数;
S230,基于所述重复传输次数和所述每一个可用时域单元的计数,进行所述第一物理信道的重复数据的发送。
基于以上技术方案,在第一物理信道的重复传输中,基于所述第一物理信道对应的多个可用时域单元进行计数,得到每一个可用时域单元的计数;然后基于所述重复传输次数和所述每一个可用时域单元的计数,进行所述第一物理信道的重复数据的发送;相当于,不管可用时域单元是否被取消,均对其进行计数,基于此,网络设备和终端设备对可用时域资源的计数结果会保持一致,进而不仅有利于提升译码性能,还有利于重复传输中网络侧和终端侧对每一次传输对应的RV版本的理解保持一致,进而提升通信质量。
在一些实施例中,所述可用时域单元包括至少一个连续的时隙或至少一个连续的符号。
在一些实施例中,所述可用时域单元为一个时隙内时域资源分配表(Time Domain Resource Allocation,TDRA)分配的至少一个符号,所述至少一个符号均用于上行传输。在一种实现方式中,针对基于Type A的PUSCH重复传输,所述可用时域单元为一个时隙内时域资源分配表TDRA分配的至少一个符号,所述至少一个符号均用于上行传输。换言之,针对一个时隙而言,所述可用时域单元为这个时隙内由TDRA分配的符号,且由TDRA分配的符号均为上行符号,此时,这些上行符号可以为所述可用时域单元;反之,如果一个时隙(slot)内TDRA分配的符号至少有一个不是上行(UL)传输的符号,则认为该时隙为不可用时隙(unavailable slot)。可对于不可用时隙,在物理信道重复传输中,不进行重复次数的计数。
在一些实施例中,所述可用时域单元为至少一个连续的符号,所述至少一个连续的符号均用于上行传输。在一种实现方式中,针对基于Type B的PUSCH重复传输,所述可用时域单元为至少一个连续的符号,所述至少一个连续的符号均用于上行传输。换言之,终端在确定可用时域单元之前,需要确定无效符号,其余的符号可以认为是潜在有效符号;如果一个时隙内连续潜在有效符号的个数大于0,这些有效的符号可作为一个可用时域单元。进一步的,如果一个时隙内连续潜在有效符号的个数大于1,则这些有效的符号可作为一个可用时域单元。
在一些实施例中,所述S230可包括:
在所述计数的初始值为1,且所述每一个可用时域单元的计数小于或等于所述重复传输次数的情况下,进行所述第一物理信道的重复数据的发送,否则,终止所述第一物理信道的重复数据的发送;或者
在所述计数的初始值为0,且所述每一个可用时域单元的计数小于或等于所述重复传输次数与1的差值的情况下,进行所述第一物理信道的重复数据的发送,否则,终止所述第一物理信道的重复数据的发送。
在一些实现方式中,所述多个可用时域单元包括被取消的可用时域单元。可选的,所述被取消的可用时域单元包括:网络设备指示的被取消的可用时域单元,和/或由于用户设备UE原因导致的但是网络设备并不知道的被取消的可用时域单元。可选的,所述由于用户设备UE原因导致的但是网络设备并不知道的被取消的可用时域单元满足以下条件中的至少一项:可用时域单元的发射功率受限;存在待发送的第一信号,所述第一信号的优先级高于所述物理信道的优先级。可选的,所述第一信号包括以下中的至少一项:物理上行控制信道PUCCH、物理随机接入信道PRACH以及探测参考信号SRS。
作为本申请的一个示例,对于带有两个上行载波的单小区操作或带有载波聚合的操作,如果在可用时域单元i中,一个频率范围内的服务小区上的PUSCH或PUCCH或PRACH或SRS传输的总UE发送功率超过某个阈值,终端可以根据以下优先级顺序(降序)向PUSCH/PUCCH/PRACH/SRS传输分配功率,使得在可用时域单元i的每个符号中,用于在频率范围内的服务小区上的传输的总传输功率小于或等于该频率范围的阈值。其中,PRACH有着更高的优先级,因此在PUSCH重复传输过程中,如果UE临时需要在用于传输PUSCH的可用时域单元上传输PRACH,由于功率受限的原因,该次PUSCH的重复传输需要被取消。这种由UE原因导致PUSCH被取消的特殊情况,网络侧并不知道。可选的,当确定在可用时域单元i中的频率范围内的服务小区的总发射功率时,其不包括在可用时域单元i之后开始发送的功率。可用时域单元中的每个符号的总UE发射功率可以为:符号中PUSCH、PUCCH、PRACH和SRS的UE发射功率的线性值之和。
在一些实施例中,所述多个可用时域单元的数量大于或等于实际进行重复数据的发送的可用时域单元的数量。
图5是本申请实施例提供的基于实际PUSCH重复进行重复传输计数的示意图。
如图5所示,假设在PUSCH重复传输过程中,如果UE临时需要在用于传输PUSCH的可用时域单元上传输PRACH,由于PRACH有着更高的优先级,考虑到功率受限的原因,该次PUSCH的重复传输需要被取消。这种由UE原因导致PUSCH被取消的特殊情况,网络侧并不知道。为了保证PUSCH实际的重复传输次数可以达到网络配置的重复次数,则UE可以推迟PUSCH重复的发送,这种情况下UE推迟发送的PUSCH重复,且基于实际PUSCH重复进行重复传输计数,以此来保证实 际重复传输的次数可以达到网络配置的重复传输次数,进而实现更好的覆盖性能,但是同样会导致网络侧由于和UE对重复次数理解不一致,进而导致网络设备不能正确接收。
图6是本申请实施例提供的基于可用时域单元进行重复传输计数的示意图。
如图6所示,对于UE引起而网络侧不可知的被取消的PUSCH重复,仍需要进行重复次数的计数,即基于可用时域单元进行重复传输计数,此时USCH重复的传输次数小于网络配置的重复传输次数。换言之,重复传输计数是基于所有的可用时域单元进行计数的(包含UE导致而网络侧不知道的潜在被取消的可用时域单元),由此,能够避免由于潜在被取消的可用时域单元带来的网络侧和UE对重复次数和重复传输使用的可用时域单元的理解不一致的问题。
通过对比图5和图6可见,本申请提供的重复传输次数的计数方式,能够保证网络设备和终端设备对可用时域资源的计数结果会保持一致,进而不仅有利于提升译码性能,还有利于重复传输中网络侧和终端侧对每一次传输对应的RV版本的理解保持一致,进而提升通信质量。
在一些实施例中,所述S230可包括:
基于所述每一个可用时域单元的计数,确定适用于所述每一个可用时域单元的冗余版本RV;
基于所述重复传输次数和适用于所述每一个可用时域单元的RV,进行所述第一物理信道的重复数据的发送。
简言之,第一设备基于所述多个可用时域单元进行重复次数的计数,记为n th,然后基于第n次可用时域单元(n th可用时域单元)来计算RV版本。
在一些实现方式中,基于适用于所述多个可用时域单元中的第一个可用时域单元的RV和所述每一个可用时域单元的计数,按照RV标识为0,2,3,1,的顺序循环的方式,确定适用于所述每一个可用时域单元的RV。
在一些实现方式中,所述第一个可用时域单元的RV为用于调度PUSCH的下行控制信息DCI指示的RV id
在一些实现方式中,按照以下表格确定适用于所述每一个可用时域单元的RV:

其中,mod表示取模运算。
下面结合图7至图8,对重复传输次数的不同计数方式对确定的RV产生的影响进行说明。
图7是本申请实施例提供的基于实际PUSCH重复的计数确定RV的示意图。
如图7所示,如果基于实际PUSCH重复进行重复传输次数的计数,则进一步需要基于实际PUSCH重复的计数确定其相应的RV。假设一个实际PUSCH重复的时域资源为一个时隙,如图7所示,存在4个实际PUSCH重复,如果这4个实际PUSCH重复中没有由于UE原因导致的但是网络设备并不知道的被取消的实际PUSCH重复,则第1个实际PUSCH重复的RV为RV0,第2个实际PUSCH重复的RV为RV2,第3个实际PUSCH重复的RV为RV3,第4个实际PUSCH重复的RV为RV1;但是,如果这4个实际PUSCH重复中存在由于UE原因导致的但是网络设备并不知道的被取消的实际PUSCH重复,例如,假设这4个实际PUSCH重复中的第1个实际PUSCH重复是由于UE原因导致的但是网络设备并不知道的被取消的实际PUSCH重复,则第1个实际PUSCH重复向后推迟,终端设备基于实际PUSCH重复的计数确定其相应的RV,此时,第1个实际PUSCH重复的RV为RV0,但网络设备会认为第1个实际PUSCH重复的RV为RV2,第2,3,4个实际PUSCH重复与第一个第1个实际PUSCH重复,即存在网络侧与UE对RV理解不一致问题。
图8是本申请实施例提供的传输时机确定RV的示意图。
如图8所示,如果基于传输时机进行重复传输次数的计数,则进一步需要基于传输时机的计数确定其相应的RV。假设一个传输时机为一个时隙,如图8所示,存在10个时隙,第1个时隙的RV为RV0,第2个时隙的RV为RV2,第3个时隙的RV为RV3,第4个时隙的RV为RV1,以此类推,第10个时隙的RV为RV2;如图8所示,假设终端可在4个时隙(即第1,2,4,8个时隙)上进行重复传输,如果这4个时隙中没有由于UE原因导致的但是网络设备并不知道的被取消的时隙,则第1个时隙的RV为RV0,第2个时隙的RV为RV2,第4个时隙的RV为RV1,第8个时隙的RV为RV1;但是,如果这4个时隙中存在由于UE原因导致的但是网络设备并不知道的被取消的时隙,例如,假设这4个时隙中的第1个时隙是由于UE原因导致的但是网络设备并不知道的被取消的时隙, 则发送第2,3,4个可用时隙的RV,这种情况下,对于部分帧结构可能会导致实际传输时没有能够自解码的RV版本,会导致译码性能恶化。
图9是本申请实施例提供的基于可用时域单元的技术确定RV的示意图。
如图9所示,如果基于可用时域单元进行重复传输次数的计数,则进一步需要基于可用时域单元的计数确定其相应的RV。如图9所示,假设一个可用时域单元为一个可用时隙,且存在4个可用时隙,如果这4个可用时隙中没有由于UE原因导致的但是网络设备并不知道的被取消的可用时隙,则第1个可用时隙的RV为RV0,第2个可用时隙的RV为RV2,第3个可用时隙的RV为RV3,第4个可用时隙的RV为RV1;如果这4个可用时隙中存在由于UE原因导致的但是网络设备并不知道的被取消的可用时隙,例如,假设这4个可用时隙中的第1个可用时隙是由于UE原因导致的但是网络设备并不知道的被取消的可用时隙,则终端设备基于可用时隙的计数确定其相应的RV,此时,第1个实际PUSCH重复的RV为RV2,第2个实际PUSCH重复的RV为RV3,第3个实际PUSCH重复的RV为RV1,基于此,网络设备和终端设备对可用时域资源的计数结果会保持一致,进而不仅有利于提升译码性能,还有利于重复传输中网络侧和终端侧对每一次传输对应的RV版本的理解保持一致,进而提升通信质量。
