本申请主张在2018年10月10日在中国提交的中国专利申请号No.201811180379.3的优先权,其全部内容通过引用包含于此。
技术领域
本公开的一些实施例涉及通信技术领域,尤其涉及一种数据传输方法及通信设备。
背景技术
网络侧设备可以为终端配置1个或多个带宽部分(Bandwidth Part,BWP)。进一步地,网络侧设备可以为BWP配置半持续调度资源,以使得通信设备可以在BWP的半持续调度资源上,采用混合自动重复请求(Hybrid Automatic Repeat Request,HARQ)进程传输数据。
目前,终端对于1个小区只能激活1个BWP。然而,在未来的通信系统中,终端对于1个小区可以激活多个BWP。在该场景中,1个小区的多个激活的BWP使用的可以是同一个HARQ实体,因此,对于激活的同一小区的多个BWP,如何为每个BWP的半持续调度资源分配HARQ实体的HARQ进程,是需要解决的问题。
发明内容
本公开的一些实施例提供一种数据传输方法及通信设备,以针对激活的同一小区的多个BWP中的每个BWP的半持续调度资源的HARQ进程的分配问题,提出解决方案。
本公开是这样实现的:
第一方面,本公开的一些实施例提供了一种数据传输方法,应用于通信设备,所述方法包括:
在目标带宽部分BWP的半持续调度资源上,采用所述目标BWP对应的 混合自动重复请求HARQ进程传输数据;
其中,第一小区的包括所述目标BWP在内的N个BWP各自对应的HARQ进程不同,N为大于1的整数。
第二方面,本公开的一些实施例还提供一种通信设备,该通信设备包括:
传输模块,用于在目标带宽部分BWP的半持续调度资源上,采用所述目标BWP对应的混合自动重复请求HARQ进程传输数据;
其中,第一小区的包括所述目标BWP在内的N个BWP各自对应的HARQ进程不同,N为大于1的整数。
第三方面,本公开的一些实施例还提供一种通信设备,该通信设备包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序,所述计算机程序被所述处理器执行时实现如上所述的数据传输方法的步骤。
第四方面,本公开的一些实施例还提供一种计算机可读存储介质,该计算机可读存储介质上存储有计算机程序,所述计算机程序被处理器执行时实现如上所述的数据传输方法的步骤。
在本公开的一些实施例中,通信设备在目标带宽部分BWP的半持续调度资源上,采用所述目标BWP对应的混合自动重复请求HARQ进程传输数据;其中,第一小区的包括所述目标BWP在内的N个BWP各自对应的HARQ进程不同,N为大于1的整数。可见,本公开可以为第一小区的不同BWP分配不同的HARQ进程,一方面可以规范第一小区的目标BWP的HARQ进程的分配,另一方面可以避免HARQ进程在不同BWP上的冲突,进而可以提高数据传输的成功率。

(每个系统帧的时隙数量×当前的系统帧号+当前系统帧的时隙编号)=[(每个系统帧的时隙数量×起始系统帧编号+起始时隙编号)+N×周期×每个系统帧的时隙数量/10]modulo(1024×每个系统帧的时隙数量)
其中,modulo表示取模运算;
每个系统帧的时隙数量可以解释为:Number Of Slots Per Frame;
当前的系统帧号可以解释为:System Fram Number,简称SFN;
当前系统帧的时隙编号可以解释为:Slot Number In The Frame;
起始系统帧编号可以解释为:SFN start time
起始时隙编号可以解释为:Slot start time
N可以表示第N个资源;
周期可以解释为:Periodicity,具体实现时,可以是网络侧设备通过RRC(Radio Resource Control,无线资源配置)消息配置的SPS资源周期。
DL SPS对于时隙的HARQ进程编号可以通过以下公式计算得出:
HARQ进程编号=[Floor(当前的时隙编号×10/(每个系统帧的时隙数量×周期))]modulo(HARQ进程数量)
其中,Floor()表示Floor函数,其功能是“向下取整”;
当前的时隙编号可以解释为:Current_Slot,具体实现时,可以通过如下公式计算得出:当前的时隙编号=[(当前的系统帧号×每个系统帧的时隙数量)+当前系统帧的时隙编号;
HARQ进程数量可以解释为:nrofHARQ-Processes,具体实现时,可以是网络侧设备通过RRC消息配置的SPS资源的HARQ进程数量。
2)UL configured grant Type 1
UL configured grant Type 1是由网络侧设备配置的周期性的上行资源,每个周期有1个上行资源分配。UL configured grant Type 1不需要PDCCH控制信令激活,RRC配置了就可以使用。
具体实现时,通信设备,如UE可以通过以下公式计算出第N个资源位置:
[(当前的系统帧号×每个系统帧的时隙数量×每个时隙的符号数量)+(当前系统帧的时隙编号×每个时隙的符号数量)+当前时隙的符号编号]=(时间域偏移量×每个时隙的符号数量+S+N×周期)modulo(1024×每个系统帧的时隙数量×每个时隙的符号数量)
其中,每个时隙的符号数量可以解释为:Number Of Symbols Per Slot,即正交频分复用(Orthogonal Frequency Division Multiplex,OFDM)符号数量;
时间域偏移量可以解释为Time Domain Offset,可以理解为相对于SFN=0的时间域的资源偏移量,如,Slot 1;
N可以表示第N个资源;S表示起始符号的编号,如,对于Slot 1的位置,起始符号为OFDM symbol 1。
UL configured grant Type 1对于时隙的HARQ进程编号通过以下公式计 算得出:
HARQ进程编号=[floor(当前符号编号/周期)]modulo(HARQ进程数量)
其中,当前符号编号可以解释为:Current_Symbol,具体实现时,可以通过如下公式计算得出:当前符号编号=(当前的系统帧号×每个系统帧的时隙数量×每个时隙的符号数量+当前系统帧的时隙编号×每个时隙的符号数量+当前时隙的符号编号。
3)UL configured grant Type 2
UL configured grant Type 2是由网络侧设备配置的周期性的上行资源,每个周期有1个上行资源分配。进一步地,网络侧设备通过PDCCH控制信令激活或去激活该SPS资源的使用。
具体实现时,可以将该PDCCH控制信令指示激活的资源位置(如,起始系统帧编号、起始时隙编号和起始符号编号)确定为资源的开始位置。通信设备,如UE可以通过以下公式计算出第N个资源位置:
[(当前的系统帧号×每个系统帧的时隙数量×每个时隙的符号数量)+(当前系统帧的时隙编号×每个时隙的符号数量)+当前时隙的符号编号]=[(起始系统帧编号×每个系统帧的时隙数量×每个时隙的符号数量+起始时隙编号×每个时隙的符号数量+起始符号编号)+N×周期]modulo(1024×每个系统帧的时隙数量×每个时隙的符号数量)
其中,起始符号编号可以解释为:Symbol start time
UL configured grant Type 2对于时隙的HARQ进程编号的计算公式,可以与UL configured grant Type 1对于时隙的HARQ进程编号的计算公式相同,具体表现为:
HARQ进程编号=[floor(当前符号编号/周期)]modulo(HARQ进程数量)
4)AUL
AUL是由网络侧设备配置的一个比特图(Bitmap)的资源分配,如,40bit中如果其中1个bit值设置成1,则该设置成1的bit对应的资源被分配给UE。进一步地,网络侧设备通过PDCCH控制信令激活或去激活该AUL资源的使用。
具体实现时,可以将该PDCCH控制信令指示激活的资源位置(如,起 始系统帧编号、起始时隙编号和起始符号编号)确定为资源的开始位置。UE在有上行数据发送的时候,可以从网络侧设备配置的HARQ进程池中自主的选择一个HARQ进程进行发送。
二、带宽部分(Bandwidth Part,BWP)介绍
在系统,如5G系统中,UE可能只能支持一个比较小的工作带宽(如5MHz),而网络侧设备的一个小区会支持比较大的带宽(如100MHz),该大带宽中的UE工作的小带宽部分则认为是BWP。
从UE配置的角度,对于不同的UE功能,可以配置1个小区下的不同BWP实现。多个不同的BWP采用的是同一个HARQ实体。
网络侧设备可配置UE有1个或多个BWP,并可通过BWP切换(Switching)命令(如PDCCH指示信息)变换UE当前激活的BWP,即激活新的BWP并去激活当前激活的BWP。当前UE对于1个小区只能激活1个BWP。
额外的,网络侧设备可以对于一个激活的BWP配置BWP非激活定时器(BWP-Inactivity Timer),UE在激活1个BWP后启动,然后在该定时器超时后将激活的BWP变换到网络配置默认的BWP(即default BWP)。
以下对本公开的一些实施例的数据传输方法进行说明。
参见图2,图2是本公开的一些实施例提供的数据传输方法的流程图。本公开的一些实施例的数据传输方法可以应用于通信设备,具体实现时,通信设备可以表现为终端,即UE或者网络侧设备。
如图2所示,本实施例的数据传输方法包括以下步骤:
步骤201、在目标带宽部分BWP的半持续调度资源上,采用所述目标BWP对应的混合自动重复请求HARQ进程传输数据。
在本公开的一些实施例中,第一小区的包括所述目标BWP在内的N个BWP各自对应的HARQ进程不同,N为大于1的整数。也就是说,第一小区的不同BWP可以通过不同的HARQ进程传输数据,从而可以避免HARQ进程在不同BWP上的冲突,进而可以提高数据传输的成功率。
另外,目标BWP的半持续调度资源可以包括以下至少一项:下行半持续调度(即DL SPS);上行配置授权类型1(即UL Configured Grant Type 1); 上行配置授权类型2(即UL Configured Grant Type 2);自主上行(即AUL)。
具体实现时,在目标BWP的DL SPS上,网络侧设备可以采用目标BWP对应的HARQ进程发送数据;在目标BWP的UL Configured Grant Type 1、UL Configured Grant Type 2或者AUL上,UE可以采用目标BWP对应的HARQ进程发送数据。
应理解的是,在本公开的一些实施例中,目标BWP可以是第一小区的N个BWP中的任一BWP,具体可根据实际需要确定,本公开的一些实施例对此不作限定。
本实施例的数据传输方法,通信设备在目标带宽部分BWP的半持续调度资源上,采用所述目标BWP对应的混合自动重复请求HARQ进程传输数据;其中,第一小区的包括所述目标BWP在内的N个BWP各自对应的HARQ进程不同,N为大于1的整数。可见,本实施例的数据传输方法可以为第一小区的不同BWP分配不同的HARQ进程,一方面可以规范第一小区的目标BWP的HARQ进程的分配,另一方面可以避免HARQ进程在不同BWP上的冲突,进而可以提高数据传输的成功率。
在本公开的一些实施例中,通信设备可以预先获取目标BWP对应的HARQ进程。
可选的,所述在目标带宽部分BWP的半持续调度资源上,采用所述目标BWP对应的混合自动重复请求HARQ进程传输数据之前,还包括:
根据半持续调度资源的配置信息,获取所述目标BWP对应的HARQ进程的编号(以下简称HARQ进程编号);
其中,所述半持续调度资源的配置信息包括:所述目标BWP的半持续调度资源的周期;和/或,所述目标BWP的半持续调度资源的HARQ配置信息。
这样,通信设备在获取目标BWP对应的HARQ进程编号后,可以在该编号对应的HARQ进程上传输数据。
在本实施例中,半持续调度资源的配置信息可以由网络侧设备确定。具体实现时,网络侧设备可以将上述半持续调度资源的配置信息下发给UE,以使UE可以根据半持续调度资源的配置信息,获取所述目标BWP对应的HARQ进程的编号。
其中,半持续调度资源的配置信息,可以用于配置目标BWP的半持续调度资源。具体地,目标BWP的半持续调度资源的周期,可以用于配置目标BWP的半持续调度资源的周期(如40毫秒);目标BWP的半持续调度资源的HARQ配置信息,可以用于配置目标BWP的半持续调度资源的HARQ信息。
具体实现时,上述周期与HARQ配置信息,可以由网络侧设备通过半持续调度资源的配置信息下发给UE;也可以由网络侧设备分开单独下发给UE,并将周期或HARQ信息携带在半持续调度资源的配置信息中,但不仅限于此。
进一步地,所述HARQ配置信息,可以包括:连续或离散的HARQ进程编号;和/或,每个周期的半持续调度资源可用的HARQ进程数量。
具体实现时,每个周期的半持续调度资源可用的HARQ进程数量可以是1,或者m,m为大于1的整数。
在一些实施方式中,所述HARQ配置信息包括的内容可以基于每个周期的半持续调度资源可用的HARQ进程数量确定。
示例性的,若每个周期的半持续调度资源可用的HARQ进程数量为1,即半持续调度资源对于每个周期有1个HARQ进程可以使用,则所述HARQ配置信息中可以不包括每个周期的半持续调度资源可用的HARQ进程数量,通信设备可以默认每个周期的半持续调度资源可用的HARQ进程数量为1,从而可以减少信令开销。
若每个周期的半持续调度资源可用的HARQ进程数量大于1,即半持续调度资源对于每个周期有1个HARQ进程可以使用,则所述HARQ配置信息中可以包括连续或离散的HARQ进程编号,以及每个周期的半持续调度资源可用的HARQ进程数量。
为方便理解,举例说明如下:
由于目标BWP可以是第一小区的N个BWP中的任一BWP,因此,可以理解的,具体实现时,HARQ配置信息可以用于:
配置方法1
在每个周期的半持续调度资源可用的HARQ进程数量为1的情况下,HARQ配置信息可以为第一小区的每个BWP的半持续调度资源配置1段连 续的HARQ进程编号(HARQ Process ID)。示例性的,BWP1的HARQ进程编号范围是0-3;BWP2的HARQ进程编号范围是4-7;
在每个周期的半持续调度资源可用的HARQ进程数量大于1的情况下,HARQ配置信息可以为第一小区的每个BWP的半持续调度资源配置1段连续的HARQ进程编号,同时指定每个周期的半持续调度资源可用的HARQ进程数量。示例性的,BWP1的HARQ进程编号范围是0-3,每个周期的半持续调度资源可用的HARQ进程数量为2;BWP2的HARQ进程编号范围是4-7,每个周期的半持续调度资源可用的HARQ进程数量为2。
配置方法2
在每个周期的半持续调度资源可用的HARQ进程数量为1的情况下,HARQ配置信息可以为第一小区的每个BWP的半持续调度资源配置离散的HARQ进程编号。示例性的,BWP1的HARQ进程编号范围是[0,2,4,6];BWP2的HARQ进程编号范围是[1,3,5,7]。
在每个周期的半持续调度资源可用的HARQ进程数量大于1的情况下,HARQ配置信息可以为第一小区的每个BWP的半持续调度资源配置离散的HARQ进程编号,同时指定每个周期的半持续调度资源可用的HARQ进程数量。示例性的,BWP1的HARQ进程编号范围是[0,2,4,6],每个周期的半持续调度资源可用的HARQ进程数量为2;BWP2的HARQ进程编号范围是[1,3,5,7],每个周期的半持续调度资源可用的HARQ进程数量为2。
需要说明的是,上述HARQ进程编号仅为示例,具体可以根据实际需要确定,本公开的一些实施例对此不作限定。
当然,在另一些实施方式中,所述HARQ配置信息可以不包括连续或离散的HARQ进程编号,目标BWP的半持续调度资源的连续或离散的HARQ进程编号可以预定义在协议中,从而可以减少信令开销。
在本实施例中,获取所述目标BWP对应的HARQ进程的编号的方式可以是根据半持续调度资源的配置信息,计算获取;或者,从半持续调度资源的配置信息中,提取获取,具体可根据实际情况确定,本公开的一些实施例对此不作限定。
示例性的,对于目标BWP的AUL,UE可以直接从半持续调度资源的配 置信息中,提取目标BWP的AUL的HARQ进程编号。具体实现时,UE可以从上述HARQ进程编号中,随机选择一个对应未被使用的HARQ进程的编号,通过该编号对应的HARQ进程进行上行数据的发送。
进一步地,所述半持续调度资源包括自主上行,所述通信设备为终端;
所述在目标带宽部分BWP的半持续调度资源上,采用所述目标BWP的混合自动重复请求HARQ进程传输数据,包括:
在目标带宽部分BWP的半持续调度资源上,采用所述目标BWP的混合自动重复请求HARQ进程传输数据,并将所述目标BWP的HARQ进程的信息发送给网络侧设备。
在该场景中,UE可以从配置的HARQ进程编号中,随机选择一个对应未被使用的HARQ进程的编号,通过该编号对应的HARQ进程进行上行数据的发送,并将该HARQ进程的信息通知给网络侧设备。
其中,HARQ进程的信息可以包括HARQ进程编号,但不仅限于此。
对于目标BWP的DL SPS、UL Configured Grant Type 1或UL Configured Grant Type 2,通信设备可以根据半持续调度资源的配置信息,计算所述目标BWP的半持续调度资源中,每个周期的半持续调度资源可用的HARQ进程编号。
需要说明的是,通信设备在计算所述目标BWP的半持续调度资源中,每个周期的半持续调度资源可用的HARQ进程编号之前,还可以包括:
根据半持续调度资源的配置信息,计算目标BWP的半持续调度资源的位置(或称为半持续调度资源位置,以下简称资源位置)。
进一步地,在每个周期的半持续调度资源可用的HARQ进程数量大于1的情况下,所述半持续调度资源的配置信息还可以包括:
所述目标BWP的半持续调度资源中,每个周期的资源分配信息;
其中,上述每个周期内的资源分配信息可以包括以下至少一项:
资源分配比特图,如,10比特标识10个时隙的位置,若某比特取值为1,则可以认为该比特标识的时隙位置的资源为分配给UE的资源;
资源分配时长,如,对于一个40ms(毫秒)周期的资源,从资源的开始位置起10ms的资源分配时长。
资源分配短周期,如,对于一个40ms周期的资源,对于每40ms有10ms的资源分配时长,在该10ms内资源分配的周期为2ms。
这样,通信设备可以基于上述每个周期的资源分配信息,计算目标BWP的半持续调度资源的位置。
具体实现时,对于DL SPS、UL Configured Grant Type 2或AUL,通信设备可以根据半持续调度资源的配置信息、激活信令(如PDCCH激活命令)指示激活的资源位置以及其各自对应的资源位置计算公式,计算得到目标BWP的资源位置。
对于UL Configured Grant Type 1,通信设备可以根据半持续调度资源的配置信息,以及UL Configured Grant Type 1对应的资源位置计算公式,计算得到目标BWP的资源位置。
这样,通信设备可以结合半持续调度资源的配置信息,以及计算得到的目标BWP的半持续调度资源的位置,计算目标BWP的每个资源位置对应的HARQ进程编号。
在实际应用中,对于目标BWP的DL SPS、UL Configured Grant Type 1或UL Configured Grant Type 2,通信设备至少可以通过以下两种计算方法计算目标BWP的每个资源位置对应的HARQ进程编号。
计算方法1
可选的,所述根据半持续调度资源的配置信息,获取所述目标BWP对应的HARQ进程的编号,包括:
根据初始HARQ进程编号和第一偏移量,计算所述目标BWP的半持续调度资源中,每个周期的半持续调度资源可用的HARQ进程编号;
其中,所述初始HARQ进程编号与所述目标BWP的半持续调度资源对应;所述第一偏移量根据所述目标BWP的半持续调度资源配置的连续的HARQ进程编号确定。
具体实现时,初始HARQ进程编号可以根据目标BWP的半持续调度资源的目标参数(如半持续调度资源的表现类型和每个周期的半持续调度资源可用的HARQ进程数量)确定。应理解的是,目标BWP的半持续调度资源的目标参数可以根据半持续调度资源的配置信息确定。
具体说明如下:
在每个周期的半持续调度资源可用的HARQ进程数量为1的情况下,由于每个周期只可以使用1个HARQ进程,说明每个周期的半持续调度资源可用的HARQ进程编号的数量也为1。
因此,具体实现时,可以根据上述目标参数,确定可以用于计算所述目标BWP的半持续调度资源中,每个周期的半持续调度资源对应的初始HARQ进程编号的第一计算公式。进一步地,基于第一计算公式加入第一偏移量,生成可以用于计算所述目标BWP的半持续调度资源中,每个周期的半持续调度资源可用的HARQ进程编号的第二计算公式。
示例1,若目标BWP的半持续调度资源的表现类型为DL SPS,每个周期的半持续调度资源可用的HARQ进程数量为1,即目标BWP的DL SPS,对于每个周期有1个HARQ进程可以使用,则上述第一计算公式可以表现为:
每个周期的半持续调度资源对应的初始HARQ进程编号=[Floor(当前的时隙编号×10/(每个系统帧的时隙数量×周期))]modulo(HARQ进程数量)
第二计算公式可以表现为:
每个周期的半持续调度资源对应的HARQ进程编号=[Floor(当前的时隙编号×10/(每个系统帧的时隙数量×周期))]modulo(HARQ进程数量)+第一偏移量
示例2,若目标BWP的半持续调度资源的表现类型为UL configured grant Type 1或UL configured grant Type 2,每个周期的半持续调度资源可用的HARQ进程数量为1,即目标BWP的UL configured grant Type 1或UL configured grant Type 2,对于每个周期有1个HARQ进程可以使用,则上述第一计算公式可以表现为:
每个周期的半持续调度资源对应的初始HARQ进程编号=[floor(当前符号编号/周期)]modulo(HARQ进程数量)
上述第二计算公式可以表现为:
每个周期的半持续调度资源对应的HARQ进程编号=[floor(当前符号编号/周期)]modulo(HARQ进程数量)+第一偏移量
其中,第一偏移量根据所述目标BWP的半持续调度资源配置的连续的 HARQ进程编号确定。
具体实现时,第一偏移量可以为:所述目标BWP的半持续调度资源配置的连续的HARQ进程编号的起始值。示例性的,若BWP1的HARQ进程编号范围是0-3,则第一偏移量可以等于0;若BWP2的HARQ进程编号范围是4-7,则第一偏移量可以等于4。
当然,第一偏移量还可以是所述目标BWP的半持续调度资源配置的连续的HARQ进程编号中的任一HARQ进程编号。示例性的,若BWP1的HARQ进程编号范围是0-3,则第一偏移量可以等于1、2或3,具体可根据实际需要决定,本公开的一些实施例对此不作限定。
第一偏移量还可以是所述目标BWP的半持续调度资源配置的连续的HARQ进程编号的起始值与预设值的和值,其中,预设值可以根据实际需要确定,本公开的一些实施例对此不作限定。示例性的,假设BWP1的HARQ进程编号范围是0-3,预设值为1,则第一偏移量可以等于1;或者,假设BWP1的HARQ进程编号范围是0-3,预设值为-1,则第一偏移量可以等于-1。
在每个周期的半持续调度资源可用的HARQ进程数量为m,m为大于1的整数的情况下,由于每个周期可以使用m个HARQ进程,说明每个周期的半持续调度资源可用的HARQ进程编号的数量也为m。需要说明的是,资源位置与HARQ进程编号一一对应,即一个资源位置分别对应一个HARQ进程编号。
因此,可选的,所述根据初始HARQ进程编号和第一偏移量,计算所述目标BWP的半持续调度资源中,每个周期的半持续调度资源可用的HARQ进程编号,具体可以表现为:
根据初始HARQ进程编号和第一偏移量,计算所述目标BWP的半持续调度资源中,每个周期的第一个半持续调度资源的HARQ进程编号;
根据每个周期的第一个半持续调度资源的HARQ进程编号、所述HARQ配置信息、周期顺序以及半持续调度资源顺序,计算所述目标BWP的半持续调度资源中,每个周期的第i个半持续调度资源的HARQ进程编号;
其中,i为大于1,小于或等于m的整数。
在该场景中,可以先计算每个周期的第一个半持续调度资源(即起始资 源)的HARQ进程编号,再基于此推算出每个周期的第i个半持续调度资源的HARQ进程编号。
具体实现时,可以根据目标BWP的半持续调度资源的目标参数,确定可以用于计算每个周期的起始资源位置对应的初始HARQ进程编号的第三计算公式。进一步地,基于第三计算公式加入第一偏移量,生成可以用于计算每个周期的起始资源位置可用的HARQ进程编号的第四计算公式。
示例1,若目标BWP的半持续调度资源的表现类型为DL SPS,每个周期的半持续调度资源可用的HARQ进程数量为m,即目标BWP的DL SPS,对于每个周期有m个HARQ进程可以使用,则上述第三计算公式可以表现为:
每个周期的第一个半持续调度资源对应的初始HARQ进程编号=[Floor(当前的时隙编号×10/(每个系统帧的时隙数量×周期))]modulo(HARQ进程数量/每个周期的半持续调度资源可用的进程数量)
上述第四计算公式可以表现为:
每个周期的第一个半持续调度资源对应的HARQ进程编号=每个周期的第一个半持续调度资源对应初始HARQ进程编号+第一偏移量=[Floor(当前的时隙编号×10/(每个系统帧的时隙数量×周期))]modulo(HARQ进程数量/每个周期的半持续调度资源可用的进程数量)+第一偏移量
示例2,若目标BWP的半持续调度资源的表现类型为UL configured grant Type 1或UL configured grant Type 2,每个周期的半持续调度资源可用的HARQ进程数量为m,即目标BWP的UL configured grant Type 1或UL configured grant Type 2,对于每个周期有m个HARQ进程可以使用,则上述第三计算公式可以表现为:
每个周期的第一个半持续调度资源对应的初始HARQ进程编号=[floor(当前符号编号/周期)]modulo(HARQ进程数量/每个周期的半持续调度资源可用的进程数量)
上述第四计算公式可以表现为:
每个周期的第一个半持续调度资源对应的HARQ进程编号=[floor(当前符号编号/周期)]modulo(HARQ进程数量/每个周期的半持续调度资源可用的进程数量)+第一偏移量
之后,可以基于每个周期的第一个资源的HARQ进程编号,推算出每个周期的第i个半持续调度资源的HARQ进程编号。具体地,可以根据每个周期的第一个半持续调度资源的HARQ进程编号、所述HARQ配置信息、周期顺序以及半持续调度资源顺序,计算所述目标BWP的半持续调度资源中,每个周期的第i个半持续调度资源的HARQ进程编号。
其中,周期顺序和半持续调度资源顺序,用于确定半持续调度资源的位置。具体地,周期顺序可以表现为第p个周期;半持续调度资源顺序可以表现为第q个半持续调度资源(以下简称资源),其中,p和q均为正整数,其具体取值可以根据实际需要决定,本公开的一些实施例对此不作限定。
示例性的,假设周期=10;HARQ进程数量=4;每个周期的半持续调度资源可用的进程数量(nrofHARQ-Processes Per Period)=2。进一步地,每个周期配置了2个资源位置,BWP1的HARQ进程编号范围是0-3。
若计算得到第1个周期的第1个资源的“HARQ进程编号=0”;第2个周期的第1个资源的“HARQ进程编号=2”;第3个周期的第1个资源的“HARQ进程编号=0”;第4个周期的第1个资源的“HARQ进程编号=2”,依次类推。则可以根据周期顺序以及半持续调度资源顺序,将剩余的HARQ进程编号按顺序分配给每个周期的后续资源,第1个周期的第2个资源的“HARQ进程编号=1”;第2个周期的第2个资源的“HARQ进程编号=3”;第3个周期的第2个资源的“HARQ进程编号=1”;第4个周期的第2个资源的“HARQ进程编号=3”,依次类推。
在实际应用中,对于计算方法1中,通信设备可以将第一偏移量,目标BWP的半持续调度资源的信息(如资源位置和周期等)代入第二计算公式中,计算得到目标BWP的半持续调度资源中,每个周期的第一个半持续调度资源可用的HARQ进程编号。
进一步地,若每个周期的半持续调度资源可用的HARQ进程编号的数量大于1,则可以根据每个周期的第一个半持续调度资源可用的HARQ进程编号,推算出每个周期的第i个半持续调度资源可用的HARQ进程编号。
另外,由于第一偏移量根据连续的HARQ进程编号确定,因此,可见,计算方法1可以适用于上述配置方法1。
计算方法2
可选的,所述根据半持续调度资源的配置信息,获取所述目标BWP对应的HARQ进程的编号,包括:
根据初始HARQ进程编号和第二偏移量,计算第一个HARQ进程编号对应的所述目标BWP的半持续调度资源;
根据第一个HARQ进程编号对应的所述目标BWP的半持续调度资源、所述HARQ配置信息、周期顺序以及半持续调度资源顺序,计算所述目标BWP的半持续调度资源中,每个周期的半持续调度资源可用的HARQ进程编号;
其中,所述初始HARQ进程编号与所述目标BWP的半持续调度资源对应;所述第二偏移量根据所述目标BWP的半持续调度资源配置的HARQ进程编号确定。另外,应理解的是,所述第一个HARQ进程编号为:所述目标BWP的半持续调度资源配置的HARQ进程编号的起始值。
需要说明的是,在计算方法2中,在每个周期的半持续调度资源可用的HARQ进程数量为1或大于1的情况下,均可以基于计算方法1中的第二计算公式,来计算第一个HARQ进程编号对应的所述目标BWP的半持续调度资源。但需要说明的是,在计算第一个HARQ进程编号对应的所述目标BWP的半持续调度资源时,需要将计算方法2中的第一偏移量替换为第二偏移量。
其中,第一偏移量和第二偏移量的区别在于:第一偏移量根据连续的HARQ进程编号确定,第二偏移量可以根据连续或离散的HARQ进程编号HARQ进程确定。需要说明的是,第二偏移量的确定方式与第一偏移量的确定方式原理相同,具体可以参考第一偏移量的确定方式的描述,本公开的一些实施例对此不作限定。
区别于计算方法1,在计算方法2中,通信设备可以先计算第一个HARQ进程编号对应的所述目标BWP的半持续调度资源的位置,再基于此,推算出所述目标BWP的半持续调度资源中,每个周期的半持续调度资源位置分别对应的HARQ进程编号。
在计算方法2中,通信设备可以将第一个HARQ进程编号代入第二计算公式或第四计算公式中,计算得到第一个HARQ进程编号对应的所述目标 BWP的半持续调度资源的位置。
之后,以该资源位置为起点,BWP上的后续资源对应的HARQ进程编号,基于该资源位置对应的HARQ进程编号依次循环增加。其中,BWP上的后续资源的位置预先计算得出。
示例性的,假设BWP1的HARQ进程编号范围是[0,2,4,6],半持续调度资源周期为10ms。
场景一、一个周期内有1个资源(即半持续调度资源),为:Slot=1。
在该场景中,若通信设备计算BWP1的HARQ进程编号=0的资源位置为(SFN=1,Slot=1),即第一个周期的第一个资源,则第二个周期的第二个资源,即(SFN=2,Slot=1)位置的HARQ进程编号=2,第三个周期的第二个资源,即(SFN=3,Slot=1)位置的HARQ进程编号=4,第四个周期的第二个资源,即(SFN=4,Slot=1)位置的HARQ进程编号=6,第五个周期的第二个资源,即(SFN=5,Slot=1)位置的HARQ进程编号=0,以此类推。
场景二、一个周期内有2个资源,分别为:Slot=1和Slot=2。
在该场景中,若通信设备计算BWP1的HARQ进程编号=0的资源位置为:(SFN=1,Slot=1),即第一个周期的第一个资源,则第一个周期的第二个资源,即(SFN=1,Slot=2)位置的资源的HARQ进程编号=2,第二个周期的第一个资源,即(SFN=2,Slot=1)位置的资源的HARQ进程编号=4,则第二个周期的第二个资源,即(SFN=2,Slot=2)位置的HARQ进程编号=6,则第三个周期的第一个资源,即(SFN=3,Slot=1)位置的HARQ进程编号=0,以此类推。
另外,由于第二偏移量可以为连续或离散的HARQ进程编号的起始值,因此,计算方法2可以适用于上述配置方法1和配置方法2。
需要说明的是,本公开的一些实施例中介绍的多种可选的实施方式,彼此可以相互结合实现,也可以单独实现,对此本公开的一些实施例不作限定。
为方便理解,以下通过具体的实施例进行说明:
实施例1:DL SPS对于每个周期有1个HARQ进程可以使用。
步骤1:网络侧设备给UE的同一个小区的多个BWP下发多个DL SPS资源的配置信息,该“资源的配置信息”包括:
资源的周期(如,40ms);
每个BWP上的DL SPS的HARQ配置信息。
其中,该“BWP上的DL SPS的HARQ配置信息”包括以下任意一种:
配置方法1:每个BWP的半持续调度资源分配1段连续的HARQ Process ID。(如,BWP1的HARQ Process ID范围是0-3;BWP2的HARQ Process ID范围是4-7)
配置方法2:每个BWP可以分配离散的HARQ Process ID。(如,BWP1的HARQ Process ID范围是[0,2,4,6];BWP2的HARQ Process ID范围是[1,3,5,7])
步骤2.1:UE根据步骤1中的配置信息,当网络侧设备发送激活信令(如,PDCCH激活命令)的时候,UE根据该激活信令给的资源位置信息,计算得出自己可用的资源位置信息,并使用该位置的资源。
步骤2.2:UE根据步骤1中配置信息,计算的出每个周期的半持续调度资源可用的HARQ进程编号(本实施例中,每个周期的半持续调度资源可用的HARQ进程数为1个)。
计算方法1:基于HARQ进程编号计算公式加入偏移量(Offset),偏移量的值为HARQ Process ID范围的起始值。如,BWP1的HARQ Process ID范围是0-3;BWP2的HARQ Process ID范围是4-7。则BWP1的Offset=0,BWP2的Offset=4。该计算方法适用于配置方法1。
如:
HARQ Process ID=[floor(Current_Slot×10/(number Of Slots Per Frame×Periodicity))]modulo(nrofHARQ-Processes)+Offset
计算方法2:UE根据HARQ进程数量和偏移量计算起始HARQ进程编号的位置(其中,该偏移量同方法1),则以该位置为起始点,后续周期的HARQ进程编号为依次循环递增。如,UE计算BWP1的HARQ Process ID=0的资源位置为(SFN=1,Slot=1),半持续资源周期为10ms,则(SFN=2,Slot=1)位置的HARQ Process ID=2,(SFN=3,Slot=1)位置的HARQ Process ID=4,(SFN=4,Slot=1)位置的HARQ Process ID=6,(SFN=5,Slot=1)位置的HARQ Process ID=0。该计算方法适用于配置方法1和配置方法2。
如:
HARQ Process ID=[floor(Current_Slot×10/(number Of Slots Per Frame×Periodicity))]modulo(nrofHARQ-Processes)+Offset
步骤2.3:网络侧设备在对应的资源位置用对应的HARQ进程发送数据。

其中,该“BWP上的DL SPS的HARQ配置信息”包括以下任意一种:
配置方法1:每个BWP的半持续调度资源分配1段连续的HARQ Process ID,同时指定每个周期的半持续调度资源可用的HARQ进程数量。如,BWP1的HARQ Process ID范围是0-3,每个周期的半持续调度资源可用的HARQ进程数量为2;BWP2的HARQ Process ID范围是4-7每个周期的半持续调度资源可用的HARQ进程数量为2。
配置方法2:每个BWP可以分配离散的HARQ Process ID,同时指定每个周期的半持续调度资源可用的HARQ进程数量。如,BWP1的HARQ Process ID范围是[0,2,4,6],每个周期的半持续调度资源可用的HARQ进程数量为2;BWP2的HARQ Process ID范围是[1,3,5,7],每个周期的半持续调度资源可用的HARQ进程数量为2。

计算方法1:基于HARQ进程编号计算公式加入偏移量,偏移量的值为 HARQ Process ID范围的起始值。(如,BWP1的HARQ Process ID范围是0-3;BWP2的HARQ Process ID范围是4-7。则BWP1的Offset=0,BWP2的Offset=4。)。该计算方法适用于配置方法1。
如:
UE每个周期的起始资源的HARQ进程编号为:
HARQ Process ID=[floor(Current_Slot×10/(number Of Slots Per Frame×Periodicity))]modulo(nrofHARQ-Processes/nrofHARQ-Processes Per Period)+Offset
UE每个周期的的后续资源的HARQ进程编号为:
根据周期顺序和资源顺序,在剩余的HARQ进程编号中按顺序分配。
如:Periodicity=10;nrofHARQ-Processes=4;“nrofHARQ-Processes Per Period=2。如,网络侧设备每个周期配置了2个资源位置。则:第1个周期的第1个资源的“HARQ进程编号=0”;第2个周期的第1个资源的“HARQ进程编号=2”;第3个周期的第1个资源的“HARQ进程编号=0”;第4个周期的第1个资源的“HARQ进程编号=2”依次类推。第1个周期的第2个资源的“HARQ进程编号=1”;第2个周期的第2个资源的“HARQ进程编号=3”;第3个周期的第2个资源的“HARQ进程编号=1”;第4个周期的第2个资源的“HARQ进程编号=3”,依次类推。
计算方法2:UE根据HARQ进程数量和偏移量计算起始HARQ进程编号的位置(其中,该偏移量同方法1),则以该位置为起始点,后续周期的HARQ进程编号为依次循环递增。如,UE计算BWP1的HARQ Process ID=0的资源位置为(SFN=1,Slot=1),一个周期内有2个资源分别为(Slot=1和Slot=2),半持续资源周期为10ms,则(SFN=1,Slot=2)位置的HARQ Process ID=2,则(SFN=2,Slot=1)位置的HARQ Process ID=4,则(SFN=2,Slot=2)位置的HARQ Process ID=6,则(SFN=3,Slot=1)位置的HARQ Process ID=0。该计算方法适用于配置方法1和配置方法2。
