技术领域
本公开涉及无线技术领域,尤其是指一种数据传输方法、网络侧设备及终端。
背景技术
相关技术中,根据物理下行控制信道(Physical Downlink Control Channel,PDCCH)的发送方式,可以将下行多传输接收点(Multi Transmission Reception Point,Multi-TRP)相干联合传输(non-coherent joint transmission,NCJT)传输分为2种:一种为基于单Single PDCCH的Multi-TRP NCJT传输,在该传输方式中,用户设备(User Equipment,UE)也可称为终端,在一个传输时间间隔(Transmission Time Interval,TTI)内只能收到一个PDCCH;一种为基于Multiple PDCCH的Multi-TRP NCJT传输,在该传输方式中,UE在一个TTI能收到多个PDCCH,分别来自于不同的TRP。
针对基于Multiple PDCCH的Multi-TRP NCJT传输方式,PDCCH本身不需要做太多的增强设计,只是需要UE具备在一个TTI监测多个PDCCH的能力,进而接收多个独立调度的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)。但是UE如何对多个独立的PDSCH进行混合自动重传请求(hybrid automatic repeatrequest,HARQ)反馈和传输则需要一些增强的设计。总的来说,有2种设计思路:
一种是基于single物理上行链路控制信道(Physical Uplink Control CHannel,PUCCH)的HARQ-确认ACK反馈,即UE针对在一个时隙内收到的由多个PDCCH调度的多个PDSCH,其对应的HARQ-ACK信息都在同一个PUCCH中反馈;
一种是基于Multiple PUCCH的HARQ-ACK反馈,即UE针对在一个时隙内收到的由多个PDCCH调度的多个PDSCH,分别在不同的PUCCH中反馈其对应的HARQ-ACK信息。
相关技术中,R15协议中PDSCH到相应的HARQ-ACK的反馈时序是由高层信令配置(dl-DataToUL-ACK)和动态信令配置(PDSCH-to-HARQ_feedback timing indicator)联合指示的,即由高层信令配置一个时序集合,下行控制信息(Downlink Control Information,DCI)在这个集合中动态选择一个时序关系进行指示,同时通过DCI中的PUCCH资源指示符(PUCCH resource indicator)指示承载HARQ-ACK使用的PUCCH资源。
基于上述方式,不难发现,有可能存在同一个服务小区Serving Cell的多个PDSCH的HARQ-ACK需要在同一个时隙slot进行传输的情况,相关技术中,新空口(New Radio,NR)有两种确定HARQ-ACK编码索引codebook的方式:半静态指示方式和动态指示方式,两种方式都会把这多个PDSCH的HARQ-ACK复用在一个PUCCH中进行传输。
进一步地,对于上述基于Multiple PUCCH的HARQ-ACK信息反馈方式,如果不同的TRP独立的确定各自PDSCH对应的DCI中的PUCCH resource indicator,可能会存在来自不同TRP的多个PDSCH对应的HARQ-ACK对应的PUCCH在同一个上行时隙发送的情况,进而可能会存在这多个PUCCH发送的时域和频域资源重叠的情况,因此UE在同一个slot反馈的对应于不同TRP的HARQ-ACK对应的PUCCH resource就有可能发生重叠。

需要说明的是,上述通信***可以包括多个UE,网络侧设备和可以与多个UE通信(传输信令或传输数据)。
本公开实施例提供的网络侧设备10可以为基站,该基站可以为通常所用的基站,也可以为演进型基站(evolved node base station,eNB),还可以为5G***中的网络侧设备(例如下一代基站(next generation node base station,gNB)或发送和接收点(transmission and reception point,TRP))或者小区cell等设备。
本公开实施例提供的用户设备可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer,UMPC)、上网本或者个人数字助理(Personal Digital Assistant,PDA)等。
为解决基于Multiple PUCCH的HARQ-ACK信息反馈方式,UE在同一个slot反馈的对应于不同TRP的HARQ-ACK对应的PUCCH resource就有 可能发生重叠,本公开实施例所述数据传输方法,通过使网络侧设备向终端发送下行控制信息DCI,DCI中的PUCCH资源指示信息用于指示一PUCCH资源组,使终端可以根据PUCCH资源组中的PUCCH资源,进行DCI对应的物理下行共享信道PDSCH的混合自动重传请求确认HARQ-ACK的反馈,避免在同一个slot反馈的对应于不同TRP的HARQ-ACK对应的PUCCH资源发生重叠。
具体地,本公开实施例所述数据传输方法,应用于网络侧设备,如图2所示,所述方法包括:
S210,向终端发送下行控制信息DCI,其中所述DCI中的物理上行链路控制信道PUCCH资源指示信息用于指示一PUCCH资源组,所述PUCCH资源组包括至少一PUCCH资源。
相较于相关技术DCI中的PUCCH资源指示信息指示一PUCCH资源,本公开实施例所述数据传输方法,通过DCI向终端指示包括至少一PUCCH资源的PUCCH资源组,使终端可以根据PUCCH资源组中的PUCCH资源,选择其中一PUCCH资源进行DCI对应的物理下行共享信道PDSCH的混合自动重传请求确认HARQ-ACK的反馈,避免在同一个slot反馈的对应于不同TRP的HARQ-ACK对应的PUCCH资源发生重叠。
可选地,所述方法还包括:
获取预先配置的至少一PUCCH资源集,其中所述PUCCH资源集中包括至少一PUCCH资源组;
选择所述PUCCH资源集中的其中一所述PUCCH资源组为所述PUCCH资源指示信息中所指示的PUCCH资源组。
采用本公开实施例所述数据传输方法,网络侧设备可以为终端配置PUCCH资源集PUCCH Resource Set,每一PUCCH Resource Set包括至少一PUCCH资源组Resource Group,在执行步骤S210之前,选择所述PUCCH资源集中的其中一所述PUCCH资源组为所述PUCCH资源指示信息中所指示的PUCCH资源组,通过DCI中的PUCCH资源指示信息指示给终端。
采用上述方式,例如在标准TS38.33F1中可以采用类似如下的方法执行:
Figure PCTCN2020070652-appb-000001
本公开实施例中,所述获取预先配置的至少一PUCCH资源集的步骤中:
通过高层信令配置获取所述PUCCH资源集,或者通过动态信令配置获取所述PUCCH资源集。
另外,在步骤S210,向终端发送下行控制信息DCI的步骤中,通过DCI格式1_0或DCI格式1_1中的PUCCH资源指示信息指示所述PUCCH资源组。
基于上述的方式,可以通过DCI中的PUCCH资源指示信息向终端指示包括至少一PUCCH资源的PUCCH资源组。
较佳地,在步骤S210,通过DCI中的PUCCH资源指示信息向终端指示包括至少两个PUCCH资源的PUCCH资源组。
本公开实施例另一方面还提供一种数据传输方法,应用于终端,如图3所示,所述方法包括:
S310,监测网络侧设备发送的下行控制信息DCI,其中所述DCI中的物理上行链路控制信道PUCCH资源指示信息用于指示一个PUCCH资源组,所述PUCCH资源组包括至少一个PUCCH资源;
S320,基于所述PUCCH资源组确定一个PUCCH资源用于混合自动重传请求确认HARQ-ACK的反馈。
本公开实施例所述数据传输方法,终端在监测到网络侧设备发送的DCI,根据DCI中的PUCCH资源指示信息确定指示一PUCCH资源组后,在进行DCI对应的DSCH的混合自动重传请求确认HARQ-ACK的反馈时,可以选 择PUCCH资源组中的其中一个PUCCH资源进行HARQ-ACK的反馈。
具体地,本公开实施例所述数据传输方法的其中一实施方式,在步骤S310,监测网络侧设备发送的下行控制信息DCI的步骤包括:
监测网络侧设备发送对应至少两个PDSCH的DCI;其中对应每一PDSCH的DCI中的PUCCH资源指示信息分别用于指示对应的所述PUCCH资源组;
基于上述方式,在步骤S320,所述基于所述PUCCH资源组确定一个PUCCH资源用于混合自动重传请求确认HARQ-ACK的反馈,包括:
从每一所述PUCCH资源组中分别选择一个PUCCH资源,形成多个PUCCH资源组合;
选择多个PUCCH资源组合中的目标PUCCH资源组合中的PUCCH资源,用于每一PDSCH的HARQ-ACK的反馈。
可以理解的是,终端接收的DCI由PDCCH承载,当获取网络侧设备发送的两个PDCCH时,两个PDCCH中的DCI中的PUCCH资源指示信息分别用于指示对应的PUCCH资源组。
具体地,在选择多个PUCCH资源组合中的目标PUCCH资源组合中的PUCCH资源,用于多个PDSCH的HARQ-ACK的反馈时,UE可以根据显式或隐式的指示或预设规则将两个PDCCH区分为第一PDCCH和第二PDCCH,其中第一PDCCH对应的PUCCH称为第一PUCCH,第二PDCCH对应的PUCCH称为第二PUCCH,第一PDCCH的PUCCH资源指示信息指示的PUCCH Resource Group表示为PUCCH Resource Group 1,第二PDCCH的PUCCH资源指示信息指示的PUCCH Resource Group表示为PUCCH Resource Group 2。
基于上述方式,在步骤S320,UE可以从PUCCH Resource Group 1和PUCCH Resource Group 2中分别选择一个PUCCH Resource形成一个PUCCH资源组合Resource Combination,当PUCCH Resource Group 1和PUCCH Resource Group 2中分别包括多个PUCCH Resource时,每从PUCCH Resource Group 1中选择一个PUCCH Resource和从PUCCH Resource Group 2中选择一个PUCCH Resource,PUCCH Resource Group 1中的多个PUCCH Resource和PUCCH Resource Group 2中的多个PUCCH Resource,可以形成多个 PUCCH Resource Combination。
例如,PUCCH Resource Group 1中的多个PUCCH Resource和PUCCH Resource Group 2中的多个PUCCH Resource相组合,若共有N种可选组合,可以组合形成N个PUCCH Resource Combination,每一PUCCH Resource Combination中包括两个PUCCH Resource,其中第一个PUCCH Resource来自于PUCCH Resource Group 1,第二个PUCCH Resource来自于PUCCH Resource Group 2。
基于上述形成的多个PUCCH Resource Combination,终端可以选择其中的一PUCCH Resource Combination为目标PUCCH资源组合,根据目标PUCCH资源组合中的PUCCH资源,进行对应每一PDSCH的HARQ-ACK的反馈。
采用上述方式,当UE根据两个PDCCH的指示需要在同一个slot内传输对应的两个PUCCH,进行DCI所对应的每一PDSCH的HARQ-ACK的反馈时,可以选择多个PUCCH资源组合中的一个目标PUCCH资源组合,避免在同一个slot反馈的对应于不同TRP的HARQ-ACK对应的PUCCH资源发生重叠。
上述以UE根据两个PDCCH的指示需要在同一个slot内传输对应的两个PUCCH,形成PUCCH Resource Combination中的PUCCH Resource为两个为例进行了说明,可以理解的是,当需要在同一个slot内传输两个以上的PUCCH时,形成多个PUCCH Resource Combination中的PUCCH Resource可以为两个以上。
本公开实施例中,所述形成多个PUCCH资源组合之后,所述方法还包括:
确定每一所述PUCCH资源组合的资源组合类型;其中所述资源组合类型为所述PUCCH资源组合中的PUCCH资源在时域和频域上完全不重叠的第一类型、为所述PUCCH资源组合中的至少部分PUCCH资源在时域或频域上重叠的第二类型、或者为所述PUCCH资源组合中的PUCCH资源在时域和频域上完全重叠的第三类型;
根据每一所述PUCCH资源组合的资源组合类型,确定所述目标PUCCH 资源组合。
具体地,采用上述的方式,通过确定从每一PUCCH资源组中分别选择的PUCCH资源所形成的多个PUCCH资源组合的资源组合类型,确定每一PUCCH资源组合的资源组合类型为第一类型、第二类型还是第三类型,根据所确定的资源组合类型,依据预设规则可以确定目标PUCCH资源组合,该目标PUCCH资源组合内的PUCCH资源能够用于在同一个时隙内进行对应至少两个PDSCH的HARQ-ACK的反馈。
具体地,确定目标PUCCH资源组合的预设规则,也即根据每一所述PUCCH资源组合的资源组合类型,确定所述目标PUCCH资源组合,包括:
当多个所述PUCCH资源组合中,至少一所述PUCCH资源组合的资源组合类型为所述第一类型时,则确定所述目标PUCCH资源组合为资源组合类型为所述第一类型的其中一PUCCH资源组合;
当多个所述PUCCH资源组合中,任一所述PUCCH资源组合的资源组合类型均不为所述第一类型,至少一所述PUCCH资源组合的资源组合类型为所述第二类型时,则确定所述目标PUCCH资源组合为资源组合类型为所述第二类型的其中一PUCCH资源组合;
当多个所述PUCCH资源组合中,每一所述PUCCH资源组合的资源组合类型均为第三类型时,则确定所述目标PUCCH资源组合为资源组合类型为所述第三类型的其中一PUCCH资源组合。
具体地,采用上述的选择方式,多个PUCCH资源组合中选择目标PUCCH资源组合的优先级顺序为第一类型的PUCCH资源组合、第二类型的PUCCH资源组合和第三类型的PUCCH资源组合。这样,当UE进行DCI对应的PDSCH的混合自动重传请求确认HARQ-ACK的反馈时,可以优先选择第一类型的PUCCH资源组合,也即优先选择所包括的PUCCH资源在时域和频域上完全不重叠的PUCCH资源组合,以避免在同一个slot反馈的对应于不同TRP的HARQ-ACK对应的PUCCH资源发生重叠。进一步地,当多个PUCCH资源组合中不存在第一类型的PUCCH资源组合时,可以进一步选择第二类型的PUCCH资源组合,也即优先选择仅有部分PUCCH资源在时域或频域上重叠的PUCCH资源组合,以降低在同一个slot反馈的对应于不同 TRP的HARQ-ACK对应的PUCCH资源发生重叠的概率。
可选地,本公开实施例中,当多个所述PUCCH资源组合中,至少两个所述PUCCH资源组合的资源组合类型为所述第一类型时,所述确定所述目标PUCCH资源组合为资源组合类型为所述第一类型的其中一PUCCH资源组合,包括:

若属于第一个PUCCH资源组的PUCCH资源的索引值最小的PUCCH资源组合的数量为至少两个,则确定属于第二个PUCCH资源组的PUCCH资源的索引值最小的PUCCH资源组合为所述目标PUCCH资源组合。
具体地,上述的第一个PUCCH资源组和第二个PUCCH资源组,可以由UE在获取网络侧设备发送对应至少两个PDSCH的DCI之后,根据对应每一PDSCH的DCI中的PUCCH资源指示信息分别用于指示的PUCCH资源组,依据显示或隐式的指示,或者依据预设规则,将多个DCI分别指示的PUCCH资源组划分为第一个PUCCH资源组、第二个PUCCH资源组等。
可选地,本公开实施例中,当多个所述PUCCH资源组合中,任一所述PUCCH资源组合的资源组合类型均不为所述第一类型,至少两个所述PUCCH资源组合的资源组合类型为所述第二类型时,所述确定所述目标PUCCH资源组合为资源组合类型为所述第二类型的其中一PUCCH资源组合,包括:
依据第二预设规则,确定资源组合类型为所述第二类型的其中一PUCCH资源组合为所述目标PUCCH资源组合;
其中,所述第二预设规则包括:

若时频资源重叠最少的所述PUCCH资源组合的数量为至少两个,则确定时频资源重叠最少的至少两个所述PUCCH资源组合中,属于第一个PUCCH资源组的PUCCH资源的索引值最小的PUCCH资源组合为所述目标PUCCH资源组合;
若属于第一个PUCCH资源组的PUCCH资源的索引值最小的PUCCH资源组合的数量为至少两个,则确定属于第二个PUCCH资源组的PUCCH资源的索引值最小的PUCCH资源组合为所述目标PUCCH资源组合。
可选地,当多个所述PUCCH资源组合中,每一所述PUCCH资源组合的资源组合类型均为第三类型时,则确定所述目标PUCCH资源组合为资源组合类型为所述第三类型的其中一PUCCH资源组合,包括:
依据第三预设规则,确定资源组合类型为所述第三类型的其中一PUCCH资源组合为所述目标PUCCH资源组合;
其中,所述第三预设规则包括:
确定资源组合类型为所述第三类型的至少两个所述PUCCH资源组合中,所包括的每一PUCCH资源的上行链路控制信息(Uplink Control Information,UCI)位数最少的PUCCH资源组合为目标PUCCH资源组合。
