为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
本公开针对相关技术在配置了重复传输时,存在不可用的重复传输机会,导致信道传输性能受到影响的问题,提供一种传输方法,对于配置了重复传输的信道,在不可用的重复机会中传输解调用参考信号(DeModulation  Reference Signal,DMRS),解决因为传输方向冲突导致一些重复传输机会不可以使用而导致重复传输性能下降的问题,提高重复传输的传输性能。
为清楚说明本公开实施例所述传输方法,以下先对重复传输的类型说明。
目前在NR通信系统中,物理上行共享信道(Physical Uplink Shared Channe,PUSCH)和物理下行共享信道(Physical Downlink Shared Channel,PDSCH)都支持重复传输。所谓重复传输,即同一个传输块(Physical Downlink Shared Channel,TB)信息,在多个传输机会中进行重复性的传输,每一个传输机会中都是一个单独的PUSCH/PDSCH信道,承载的TB是同一个TB信息。
PUSCH包括配置许可(Configured Grant,CG)PUSCH和动态许可(Dynamic Grant,DG)PUSCH。DG PUSCH即具有物理下行控制信道(Physical Downlink Control Channel,PDCCH)调度的PUSCH,终端通过调度请求(Scheduling Request,SR)向基站请求数据传输,基站通过上行许可(Uplink grant,UL grant)调度一个PUSCH传输。CG PUSCH没有调度信令,是一种半静态传输,根据高层信令配置的周期确定一些周期性的传输机会,当有数据要传输时,可以自行在最近的传输机会中进行PUSCH传输。CG PUSCH分为类型type1和type2两种,type1CG PUSCH的所有传输参数,包括时域资源(起始符号、符号个数和重复次数等)、频域资源、天线端口、DMRS等参数都是由高层信令预先配置的。Type2CG PUSCH是通过PDCCH激活,激活之后按照配置的周期确定周期性传输机会,其中,激活信令可以通知一部分传输参数,例如时域资源(起始符号、符号个数和重复次数等)、频域资源、天线端口、DMRS等参数。此外,还可以通过发送去激活PDCCH来释放type2 CG PUSCH的资源。
对于PUSCH,在R15中仅支持一种重复传输方式,即基于时隙的重复传输。具体的,高层信令(例如pusch-Aggregation Factor信令)预先配置重复传输的次数(又称Aggregation factor,简单起见用N表示),N次重复传输,表示PUSCH占用N个时隙传输,每个时隙中在相同的PUSCH资源上传输相同的TB信息。对于具有PDCCH调度的PUSCH,N个时隙是根据调度PUSCH的PDCCH中的时域资源分配(Time Domain Resource Allocation,TDRA)指 示域中的K2(定义PDCCH所在时隙和被调度的PUSCH所在时隙之间的时隙间隔,例如PDCCH在时隙n传输,则被调度的PUSCH在时隙n+k2传输)确定被调度的PUSCH传输的第一个时隙,并根据TDRA中的起始和长度指示值(Start and length indicator value,SLIV)确定在一个时隙中的起始符号和符号个数。对于CG PUSCH,第一个时隙是根据高层信令或激活PDCCH中通知的相关参数确定的。然后,对于DG PUSCH和CG PUSCH,基于第一个时隙,连续向后确定的N-1个时隙,每个时隙中都是按照相同的起始符号和符号个数确定这个时隙中的PUSCH传输的时域位置,如果其中一个时隙中根据起始符号和符号个数确定的符号集合中包含高层信令(例如tdd-UL-DL-ConfigurationCommon,or tdd-UL-DL-ConfigurationDedicated)配置的下行符号,则确定这个符号集合不可用,在这个时隙中不传输PUSCH,但还是记录一次重复传输,如图1所示,也就是如果出现了N个时隙中的N1个时隙中确定的符号集合不可用,则实际只有N-N1次重复传输。
对于PUSCH,在R15中除了支持上述基于时隙的重复传输(重复类型A,repetition type A),还支持重复类型B(repetition type B)。对于repetition type A,扩展了repetition次数的配置方式,除了高层信令预先配置重复repetition次数之外,还可以通过在TDRA表格中增加一列表达重复repetition次数(通过repetitionNumber-r16配置),这样下行控制信息(Downlink Control Information,DCI)在动态调度一个PUSCH传输时,可以从TDRA表格中选择一个合适的repetition次数与SLIV和K2一起指示给终端,从而实现动态改变重复传输次数。对于repetition type B,就是根据调度PUSCH的PDCCH(或DCI)中指示的起始符号,传输符号个数确定每个repetition的传输机会(即时域资源,具体表现为符号集合),重复传输次数可以是类似repetition type A的方式得到的;第一个repetition PUSCH的时域资源直接根据DCI指示的起始符号和符号个数确定,后续的repetition的时域资源则在第一个repetition之后顺序的确定,每个传输机会对应相同的符号个数,起点就是前一个repetition之后的第一个符号,这样划分得到的N个连续的repetition传输机会,其中的每一个传输机会对应一个名义重复机会Nominal repetition(即按照配置参数划分的repetition,但并不一定实际传输),如果一个传输机会对 应的符号集合中包含了高层信令配置的DL符号或者不可用符号,则这个Nominal repetition会被分割为多个实际重复机会Actual repetition(即实际传输的repetition),每个Actual repetition都仅包含可以用于传输的符号,比如上行符号或Flexible符号。多个repetition PUSCH可以在同一个时隙中,也可以分布在不同的时隙中。具体如图2所示。对于名义重复机会到实际重复机会划分的过程中得到的传输长度(符号个数)比较短的actual repetition,例如1个符号的Actual repetition,除非调度信令配置的传输长度就是1符号,否则这样的actual repetition是不传输的。
对于PDSCH,仅支持一种重复传输方式,即基于时隙的重复传输。具体的,高层信令(例如pdsch-AggregationFactor,repetitionNumber-r16)预先配置重复传输的次数(又称Aggregation factor,简单起见用N表示),N次重复传输,表示PDSCH占用N个时隙传输,每个时隙中在相同的PDSCH资源上传输相同的TB信息。对于具有PDCCH调度的PDSCH,N个时隙是根据调度PDSCH的PDCCH中的TDRA指示域中的K0(定义PDCCH所在时隙和被调度的PDSCH所在时隙之间的时隙间隔,例如PDCCH在时隙n传输,则被调度的PDSCH在时隙n+k0传输)确定被调度的PDSCH传输的第一个时隙,并根据TDRA中的SLIV确定在一个时隙中的起始符号和符号个数,然后基于第一个时隙,向后一次寻找到临近的N-1个时隙,每个时隙中都是按照相同的起始符号和符号个数传输的,如果其中一个时隙中根据起始符号和符号个数确定的符号集合中包含高层信令(例如tdd-UL-DL-ConfigurationCommon,or tdd-UL-DL-ConfigurationDedicated)配置的上行符号,则确定这个符号集合不可用,在这个时隙中不接收PDSCH,但还是记录一次重复传输,也就是如果出现了N个时隙中的N1个时隙中确定的符号集合不可用,则实际只有N-N1次重复传输。
在R17中,因为复杂的环境或小区边缘的干扰,可能影响信号或信道传输的覆盖范围,因此提出了覆盖增强(Coverage enhancement),对于需要进行覆盖增强的终端,重复传输是一项重要手段,此外还可以考虑重复传输过程中使用多个传输机会中的DMRS进行联合信道估计,以提升信道估计性能。
在R17中,为了降低NR终端的成本和体积,更好的适用于可穿戴设备 等方面的需求,提出了降低复杂度的终端(RedCap终端),对这类终端,可能因为复杂度和硬件指标的降低,例如降低带宽和天线等,导致传输性能下降,重复传输也是弥补传输性能下降的一个重要方案。
然而,在配置了重复传输时,重复传输的PUSCH或PDSCH在其中一个或多个重复传输机会中,可能因为与半静态配置的符号方向发生冲突,而导致这个传输机会不能用于重复传输,从而使得实际的重复传输次数无法达到目标重复传输次数,导致信道传输性能受到影响。
为解决上述技术问题,本公开实施例提供一种传输方法,能够解决相关技术在配置了重复传输时,存在不可用的重复传输机会,导致信道传输性能受到影响的问题。
如图3所示,本公开其中一实施例提供一种传输方法,应用于发送端,包括:
S301,在配置了重复传输的信道中,若N个重复机会中存在不可用重复机会,则在所述不可用重复机会中,仅传输解调用参考信号DMRS;

其中,采用不同方式确定重复机会时,重复机会的总次数N的确定方式分别可以参阅以上的描述,在此不再说明。
以下对基于不同类型的重复机会时,采用本公开实施例所述传输方法的具体方式进行说明。
对于N个重复机会为基于时隙的重复机会,或者为基于重复类型A的重复机会:
一方面,可选地,N个重复机会为基于时隙的重复机会,或者为基于重复类型A的重复机会时,N个重复机会为基于为所述信道所分配的起始符号、传输符号个数和调度时序确定。

依据N个重复机会中的可用重复机会中传输DMRS的符号位置,在所述不可用重复机会对应的符号集合中的可用符号上传输DMRS。
也即,具体地,按照上述方式之一确定传输DMRS的符号(也即时域资源)。
其中,当在所述不可用重复机会对应的符号集合中的所有可用符号上都传输DMRS时,可用符号也即为不可用重复机会对应的符号集合中去掉不可用符号之外的符号;

当依据N个重复机会中的可用重复机会中传输DMRS的符号位置,在所述不可用重复机会对应的符号集合中的可用符号上传输DMRS时,也即,按 照每一重复机会中的DMRS图样确定在一个重复机会对应的符号集合中传输DMRS的符号,如果对应的传输DMRS的符号在不可用重复机会中是可用的,则传输DMRS,如果对应的传输DMRS的符号在不可用重复机会中是不可用的,则在不可用符号上不传输DMRS。
一方面,在步骤S301,在不可用的重复机会中,传输DMRS时,采用以下其中之一方式,确定所述不可用重复机会传输DMRS的频域资源:
所述不可用重复机会中传输DMRS的频域资源为配置重复传输的信道的频域资源;
在不同的重复机会对应的频域资源大小不同的情况下,按照多个重复机会,或者多个重复机会中的与所述不可用重复机会相邻的重复机会对应的频域资源中的最大值、最小值或并集,确定所述不可用重复机会中传输DMRS的频域资源。
具体地,传输DMRS的频域资源可以为重复信道的频域资源(如DMRS在重复信道传输所分配的RB集合中传输);或者
如果不同的重复机会对应的频域资源大小不同,则按照多个重复机会或多个重复机会中的与不可用重复机会相邻的重复机会(前、后)对应的频域资源中的最大值或最小值或并集确定DMRS的频域资源。
一方面,在步骤S301,在不可用的重复机会中,传输DMRS时,采用以下其中之一方式,确定所述不可用重复机会传输DMRS的DMRS序列:

第六方式:在所述DMRS序列与所述不可用重复机会之前的一个可用重复机会或者所述不可用重复机会之后的一个可用重复机会中的DMRS序列相同时,若所述不可用重复机会中的DMRS传输符号为所述可用重复机会中的DMRS传输符号的子集,或者所述不可用重复机会中的DMRS传输符号部分地包括在所述可用重复机会的DMRS传输符号中,则对于所述不可用重复机会的DMRS传输符号中,包括在所述可用重复机会的DMRS传输符号中的DMRS传输符号,依据所述可用重复机会中的相应符号上的DMRS序列传输;
第七方式:在所述DMRS序列与所述不可用重复机会之前的一个可用重复机会或者所述不可用重复机会之后的一个可用重复机会中的DMRS序列相同时,对于不包括在所述可用重复机会的DMRS传输符号中的DMRS传输符号,重用所述第一方式至第五方式中的任一种确定所传输的DMRS序列。
本公开实施例中,可选地,在采用所述DMRS序列与N个重复机会中所有可用重复机会中的DMRS序列相同的方式,确定所述不可用重复机会传输DMRS的DMRS序列时,DMRS序列与所有可用重复机会中的DMRS序列相同,此时每个重复机会中的每个符号上的DMRS序列都是相同的,例如使用低峰值与均值比(Peak-to-Average Power Ratio,PAPR)序列type1产生DMRS,或使用低PAPR序列type2产生长度不超过30的DMRS,DMRS的产生与符号编号、时隙编号无关,因此可以保证任何时隙任何符号上的DMRS序列都是相同的。

所述预编码与所述不可用重复机会的前M个和/或后Q个连续的可用重 复机会中信道传输所使用的预编码方式一致;

一方面,对于N个重复机会为基于重复类型B的重复机会,在步骤S301,在不可用的重复机会中,仅传输DMRS时,包括:

本公开实施例所述传输方法,可选地,所述方法还包括:
根据预设信令指示,确定是否执行在所述不可用重复机会中仅传输解调用参考信号DMRS的步骤。
具体地,采用本公开实施例所述方法,可以根据预设信令的预先配置确 定是否执行在不可用重复机会中,仅传输解调用参考信号DMRS的步骤,也即开启或者关闭执行该功能。
这样,根据预设信令的配置确定是否在不可用repetition机会中传输DMRS,如果确定传输,则按照上述方式传输。
可选地,预设信令可以是高层信令和/或物理层信令等。
本公开实施例所述传输方法,所述发送端可以为终端或基站。其中对于终端,配置了重复传输的信道为上行信道,如为发送PUSCH信道;对于基站,配置了重复传输的信道为下行信道,如为发送PDSCH信道。
以下结合具体实施方式,对本公开实施例所述传输方法的具体过程详细说明。
如图4所示,设定PUSCH被配置采用基于时隙或重复类型A进行重复传输,配置的重复传输次数为4,即在4个连续的时隙中传输,按照PUSCH的调度或配置信息(包括起始符号,符号个数,以及K2等信息),确定PUSCH的重复repetition传输从时隙n到时隙n+3,每个重复传输的PUSCH承载相同的TB,在一个时隙中占用这个时隙中的第8-14个符号传输,即时隙n到时隙n+3中的每个时隙中的第10-14个符号(共计5个符号,起始符号是编号为9的符号,其中编号从0开始,即第10个符号)构成一个repetition机会,其中,假设每个repetition机会所对应的符号集合中传输PUSCH时,DMRS在符号集合中的5个符号中的第一个和最后一个符号上传输,假设时隙n+2中的repetition机会对应的符号集合(即时隙n+2中的第10-14个符号,即编号为9-13的符号,下同)中的第1和2个符号(即该时隙中的第10和11个符号,该时隙中编号为9和10的符号,编号从0开始,下同)为高层信令配置的DL符号。
对于终端侧:
终端在时隙n、n+1和n+3中,在第10-14个符号上发送PUSCH,其中PUSCH的DMRS在所占用的5个符号中的第1个符号(即时隙中编号为9的符号)和最后一个符号(即时隙中编号为13的符号)上传输;确定第3个repetition机会(即时隙n+2中)对应的符号集合因为包含了2个DL符号(不可用符号),确定为不可用重复repetition机会,因此终端确定在不可用 repetition机会中不传输PUSCH(数据),仅传输DMRS;具体的按照如下方式在时隙n+2中传输DMRS:
1)确定DMRS的传输符号:
方式1-1:确定在不可用repetition机会对应的符号集合中除去DL符号之外的所有符号上传输DMRS,即时隙n+2中的repetition机会对应的符号集合中的第3-5个符号(即时隙中编号为11、12、13的符号)上传输DMRS;如图5所示;
方式1-2:约定或配置在不可用repetition机会对应的符号集合中的可用符号中的部分符号上传输,例如约定或配置在可用符号中的第一个符号和/或最后一个符号上传输等,即确定在时隙n+2中的repetition机会对应的符号集合中的第3个符号(即时隙中编号为11的符号)和/或第5个符号(即时隙中编号为13的符号)上传输DMRS;如图6a至图6c所示;
方式1-3:确定在不可用repetition机会对应的符号集合中除去DL符号之外的符号集合中按照可用repetition机会中的DMRS符号位置传输DMRS,即时隙n+2中的repetition机会对应的符号集合中的第5个符号(即时隙中编号为13的符号)上传输DMRS(因为第1个符号是不可用符号,虽然对应可用repetition机会中的DMRS符号位置,但因为该符号不可用,不能用来传输DMRS);如图7所示。2)确定DMRS传输的频域资源:
方式2-1:在分配给每个重复repetition PUSCH的频域资源上传输,即调度或配置信令中分配给PUSCH的RB集合,假设每个repetition的RB集合相同;
方式2-2:在分配给每个repetition PUSCH的频域资源的并集上传输DMRS,例如第1、2和第4个repetition分别对应RB1-3、RB2-4和RB3-5,则确定在RB1-5上传输DMRS;
方式2-3:在分配给与不可用repetition相邻的repetition PUSCH的频域资源的并集上传输DMRS,例如第2和第4个repetition分别对应RB2-4和RB3-5,则确定在RB2-5上传输DMRS,不排除按照其他方式确定DMRS的频域资源;
其中,对于上述任一种方式确定的RB集合中,按照相关技术定义的 DMRS在一个RB中的映射方式传输DMRS。
3)产生DMRS序列:
方式3-1:DMRS序列按照假设在该repetition机会进行信道传输时产生;即,根据当前不可用repetition机会所在的时隙编号
Figure PCTCN2021126116-appb-000001
DMRS传输所对应的符号在该时隙中的编号(l=11、12、13对于方式1-1,l=11,13对于方式1-2,l=13对于方式1-3),按照如下公式1或公式2,计算得到DMRS的基本序列;
方式3-2:DMRS序列基于前1个或后1个可用repetition机会的时隙编号以及DMRS在不可用repetition机会中的符号编号确定DMRS序列;即根据时隙编号
Figure PCTCN2021126116-appb-000002
DMRS编号(l=11,12,13对于方式1-1,l=11,13对于方式1-2,l=13对于方式1-3),按照如下公式1或公式2,计算得到DMRS的基本序列;
方式3-3:DMRS序列与前1个或后1个可用repetition机会中的DMRS序列相同;例如,与时隙n+1中的DMRS序列相同,则因为时隙n+1中DMRS是在编号为9和13的符号上传输,与上述方式1-1到1-3中确定的在时隙n+2中传输的DMRS符号,仅符号13是对应的,则根据时隙编号
Figure PCTCN2021126116-appb-000003
DMRS编号l=13,按照如下公式,计算得到编号为13的符号上的DMRS的基本序列,在时隙n+2中的编号为13的符号上按照该方式确定的DMRS序列传输,而对于方式1-1确定DMRS符号中不包含在时隙n+1中传输的DMRS符号中的符号,如编号为11和12的符号,对于方式1-2确定DMRS符号中不包含在时隙n+1中传输的DMRS符号中的符号,如编号为11的符号,还需要按照上述方式3-1或3-2中的一种确定每个符号上的DMRS序列进行传输;
方式3-4:DMRS序列与每一个可用repetition机会中的DMRS序列相同;此时相当于假设按照如下公式2计算DMRS,且满足不使用伪随机序列的情况,则任何repetition中任何符号上的DMRS序列都相同,在不可用repetition机会中确定传输DMRS的符号,按照任何一个repetition中任何一个符号上传输的DMRS序列传输即可;
上述每一种方式中,在确定了DMRS产生方式之后,按照相应的方式产生一个符号上的DMRS的方式可以参见相关协议内容。
公式1:对于不使用预变换(离散傅立叶变换(Discrete Fourier Transform,DFT))的PUSCH,按照如下公式计算每个符号上的DMRS序列:
Figure PCTCN2021126116-appb-000004

公式1.1:

公式2:对于使用预变换的PUSCH,按照如下公式计算每个符号上的DMRS序列:
Figure PCTCN2021126116-appb-000010
其中,
Figure PCTCN2021126116-appb-000011
为按照相关技术确定的ZC序列,如果使用低峰值与均值比(Peak-to-Average Power Ratio,PAPR)序列type1产生,则与伪随机序列c()无关,每个时隙的每个符号上产生的DMRS序列都是相同的,如果使用低PAPR序列type2产生,当产生的序列长度小于30时,与伪随机序列c()无关,每个时隙的每个符号上产生的DMRS序列都是相同,当产生的序列长度大于或等于30时,
Figure PCTCN2021126116-appb-000012
根据伪随机序列产生,其中,伪随机序列c()是按照下述公式2.1进行初始化的,其中,

4)终端按照上述方式确定的DMRS的时域资源和频域资源、以及产生的DMRS序列传输DMRS,其中,上述确定时域资源、频域资源的步骤在执行上不分先后顺序;如果DMRS需要进行预编码,则采用的预编码方式需要与时隙n+2其他repetition机会(如时隙n、n+1和n+3中的repetition机会),或与时隙2前后相邻的repetition机会(如时隙n+1和n+3中的repetition机会)中所使用的预编码方式是相同的,从而支持基站可以使用这些时隙中的DMRS进行联合信道估计。
对于基站侧:
按照上述同终端侧一致的判定方式,确定在时隙n、n+1和n+3中,在第10-14个符号上接收PUSCH,其中PUSCH的DMRS在所占用的5个符号中的第1和最后一个符号上传输;在时隙n+2中,仅在按照与上述终端对应发送DMRS的符号上接收DMRS(具体的确定DMRS传输符号和频域资源以及DMRS序列的方式同上终端侧,这里不再赘述),其中,因为终端发送时,保证了时隙n+2中的DMRS的预编码方式与前面和/或后面的repetition机会中传输的PUSCH的预编码方式相同,从而可以实现联合信道估计,即基于这个时隙中的DMRS与前面和/或后面的repetition机会中的DMRS在一起进行信道估计,从而提高信道估计的性能,进而提高PUSCH重复传输的传输性能。
上述实施方式中,以PUSCH为例,PUSCH是否采用跳频方式,可能对应不同的DMRS传输方式,但都是相关协议所规定的,都可以适用上述方式在不可用的repetition机会中进行DMRS传输;PUSCH是否采用预变换方式(即波形是基于离散傅立叶变换扩展OFDM(Discrete Fourier Transform-Spread OFDM,DFT-s-OFDM)的还是循环前缀OFDM(Cyclic Prefix OFDM,CP-OFDM的),都可以使用上述方式,所不同的就是不同的波形DMRS产生和映射的方式不同,具体参考相关技术的规定;上述仅以每个时 隙中PUSCH的重复传输资源都相同为例,如果配置或者调度信令可以分别指示每个repetition的传输资源,则每个repetition机会的符号集合的位置和大小中的至少一个可以不同,频域资源也可以不同;
需要说明的是,上述实施例仅以PUSCH为例,对本公开实施例所述传输方法进行了详细说明。当所述传输方法应用PUCCH、PDSCH、PDCCH等信道传输时,可以采用类似的方式,只不过需要按照各自信道的定义方式确定DMRS的传输图样;如果为下行信道,如PDSCH、PDCCH等,则上述终端行为是在不可用repetition机会中接收DMRS,基站的行为则是在不可用机会中发送DMRS。
另外,上述仅以高层信令配置的DL符号作为不可用符号为例,其他的不可用符号定义,例如SSB符号、对于CG PUSCH情况下SFI指示为Flexible的符号(高层信令配置这个符号也是flexible符号)等也适用于上述方式;对于不同信道,不可用符号的定义可能不同,这些变化都包含在本公开所述传输方法中。
本公开另一实施例还提供一种传输方法,应用于接收端,如图8所示,所述方法包括:
