PDSCH时域资源分配方法、终端及计算机可读存储介质
相关申请的交叉引用
本申请主张在2018年7月13日在中国提交的中国专利申请No.201810771945.1的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种PDSCH时域资源分配方法、终端及计算机可读存储介质。
背景技术
5G NR系统支持为用户设备(User Equipment，UE)配置一个或多个载波(component carrier，CC)或小区。当UE配置为单载波模式或载波聚合(carrier aggregation，CA)下的自调度模式时，每个CC或小区可配置多个控制资源集(control-resource set，CORESET)以及多个搜索空间集，包括公共搜索空间(common search space，CSS)以及UE特定搜索空间(UE-specific search space，USS)。网络可以为每个搜索空间集灵活配置盲检数目，CORESET与搜索空间集之间可以灵活关联。
如果某些小区的信道质量不够好或信道阻塞概率较高时，网络可以为UE配置跨载波调度，即把控制信道配置在其他信道质量较好的小区(例如，主小区)，来跨载波调度其他小区(例如，辅小区)的数据。调度小区与被调度小区的子载波带宽(sub-carrier spacing，SCS)可以相同也可以不同。调度小区可以为自调度模式，此时调度小区仅调度自己。如果调度小区被配置为跨载波调度，则调度小区还可以调度一个或多个自己以外的被调度小区。被调度小区没有自己的物理下行控制信道(physical downlink control channel，PDCCH)，只能由调度小区来执行调度操作。
UE监听PDCCH来接收下行控制信息(downlink control information，DCI)，根据DCI的指示来解调基站调度的物理层下行共享信道(physical downlink shared channel，PDSCH)。DCI可以灵活指示PDSCH的资源分配，例如， PDSCH的所在的小区或带宽部分(bandwidth part，BWP)，频域资源以及时域资源等。其中，时域资源可以指示PDSCH的时隙偏移即slot offset，起始OFDM符号以及符号长度等。PDSCH的起始OFDM符号不能早于PDCCH的起始OFDM符号。
由于PDSCH的起始符号可能跟PDCCH的起始OFDM符号相同，因此UE在接收并盲检测PDCCH的同时，必须把被调度小区的整个BWP的数据先缓存起来。对于自调度或跨载波调度且调度小区的SCS(即PDCCH的SCS)与被调度小区的SCS(PDSCH的SCS)相同时，UE需要缓存被调度小区的整个BWP数据一直到PDCCH解调完毕为止。但PDCCH的SCS小于PDSCH的SCS时，UE接收PDCCH的时长远大于PDCCH的SCS小于PDSCH的SCS的情况下UE接收PDCCH的时长，相应地UE所缓存的数据的时长将变长，UE所缓存的数据量较相同SCS的情况下将增大，UE数据缓存负荷增大。
可见，目前迫切需要本领域技术人员解决的技术问题为，在PDCCH的SCS小于PDSCH的SCS的情况下，如何能够降低UE的数据缓存负荷。
发明内容

第二方面，本公开实施例还提供一种PDSCH时域资源分配终端，其中，所述终端包括：处理器用于不早于PDSCH的时域限制位置开始缓存或接收所述PDSCH，其中，所述PDSCH的时域位置不早于所述PDSCH的时域限制位置。

第四方面，本公开实施例还提供一种计算机可读存储介质，包括：所述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前述的PDSCH时域资源分配方法中的步骤。
本公开实施例提供的技术方案，终端不早于PDSCH的时域限制位置开始缓存或接收PDSCH，其中，在PDCCH的SCS小于PDSCH的SCS情况下，PDSCH的时域位置不早于PDSCH的时域限制位置，相较于相关技术中从开始接收PDCCH时便开始进行数据缓存，可以减少数据缓存量，降低能耗。

参照图1，示出了本公开一些实施例提供的PDSCH的时域资源分配方法的步骤流程图。
本公开实施例的PDSCH时域资源分配方法包括如下步骤：
步骤101：终端不早于PDSCH的时域限制位置开始缓存或接收PDSCH。
在PDCCH的SCS小于PDSCH的SCS情况下，PDSCH的时域位置不早于PDSCH的时域限制位置。其中，PDSCH的时域位置不早于PDSCH的时域限制位置即PDSCH的时域位置等于或者晚于PDSCH的时域限制位置。
PDSCH时域位置包括：PDSCH的时隙偏移、PDSCH的起始OFDM符号中的一个或多个，相对应地，时域限制位置为对时隙偏移的限制和/或对起始OFDM符号位置的限制。
PDSCH的时域限制位置可以与PDCCH的SCS第一配置值、PDSCH的SCS第二配置值、PDCCH的处理时间、PDCCH的时域长度、PDCCH的起始符号位置、PDCCH的结束符号位置以及参考OFDM符号中的一个或多个因子相关。PDSCH的时域限制位置与上述一个或多个因子的关系可由协议预定义或网络设备所配置或由终端确定。对于PDSCH的时域限制位置与上述一个或多个因子的具体相关关系可参照后续实施例中的相关描述。对于确定PDSCH的时域限制位置的具体方式，可由本领域技术人员根据实际需求进行设置，能够保证PDSCH时域位置不早于PDSCH的时域限制位置即可。
本公开实施例提供的PDSCH时域资源分配方法，适用于终端如用户设备UE。
例如时域限制位置为5，则可从第五个单位位置处开始缓存被调度小区BWP数据，也可以从第四个、第三个或者第二个单位位置处开始缓存被调度小区的BWP数据，本公开实施例中通过限制PDSCH的时域位置分配，可以避免终端额外缓存更多数据。
本公开实施例提供的PDSCH时域资源分配方法，终端不早于PDSCH的时域位置开始缓存或接收PDSCH，其中，在PDCCH的SCS小于PDSCH的SCS情况下，PDSCH的时域位置不早于PDSCH的时域限制位置，相较于相关技术中从开始接收PDCCH时便开始进行数据缓存，可以减少数据缓存量，降低能耗。
参照图2，示出了本公开一些实施例提供的PDSCH的时域资源分配方法的步骤流程图。
本公开实施例的PDSCH时域资源分配方法包括以下步骤：
步骤201：依据PDSCH的SCS第二配置值与PDCCH的SCS第一配置值确定第一中间值。
SCS的配置值用表示，配置值不同则其对应的Δf即子载波频率间隔不同。
具体地，SCS的配置值与Δf二者的对应关系如表1所示：
表1
μ Δf＝2 μ·15[kHz]
0 15
1 30
2 60
3 120
4 240
网络设备通过RRC(Radio Resource Control，无线资源控制)为终端配置了两个小区A与B，其中A是主小区即调度小区，B是辅小区即被调度小区，A跨载波调度B。网络侧配置了A小区的BWP上的PDCCH。A的SCS为μ PDCCH＝0，(即15kHz)，B的SCS为μ PDSCH＝2(即60kHz)。
μ PDCCH为第一配置值，μ PDSCH为第二配置值。
第一中间值为依据第一配置值与第二配置值按照第一预设规则计算所得到的值。第一中间值可以为第二配置值与第二配置的差值，也可以为第一配置值与第二配置值差值的预设倍数，还可以为第一配置值与第二配置的加权平均值等，对于第一预设规则可以由本领域技术人员根据实际需求进行设置，本公开实施例中对此不做具体限制。
本公开实施例中以第一中间值为第二配置值与第一配置值的差值为例进行说明。本公开实施例中第二配置值为2，第一配置值为0，则PDSCH的SCS第二配置值与PDCCH的SCS第一配置值的差值则为2-0＝2。
步骤202：依据系统中预设的时域限制位置与第一中间值的对应关系，将第一中间值对应的时域限制位置，确定为PDSCH的时域限制位置。
本公开实施例中以时域限制位置为对时隙偏移K0的限制为例进行说明。
系统中预设的时域限制位置与第一中间值的对应关系具体可由本领域技术人员根据实际需求进行设置。由于第一配置值可以有多个，第二配置值也可以有多个，第一配置值与第二配置值的第一中间值也有多个，系统可以预 设不同第一中间值与时域限制位置之间的对应关系。一种示例性的举例如表2所示：
表2
μ PDSCH-μ PDCCH L(slot)
0 0
1 1
2 2
3 3
表2中，L则为时域限制位置。
由于步骤201中所确定的第一差值为2，则其对应的时域限制位置L则为2。
本公开实施例中以基于第一配置值、第二配置值确定PDSCH的时域限制位置为例进行说明。在具体实现过程中，PDSCH的时域限制位置可以为系统中预设的时域限制位置，即L系统中预设的固定常量，K0≥L。
对于系统中预设的时域限制位置的具体值，可以由本领域技术人员根据实际需求进行设置，例如：设置为1、2或者3等，本公开实施中对此不做具体限制。
步骤203：终端不早于PDSCH的时域限制位置开始缓存或接收PDSCH。
在PDCCH的SCS小于PDSCH的SCS情况下，PDSCH的时域位置不早于PDSCH的时域限制位置。
在确定PDSCH的时域限制位置后，终端在盲检测PDCCH时，可以只从时域限制位置指示的时间即K0＝L开始缓存数据，直到解调到DCI，根据DCI实际指示的时域位置K0接收PDSCH。
本公开实施例提供的PDSCH时域资源分配方法，终端不早于PDSCH的时域限制位置开始缓存或接收PDSCH，其中，在PDCCH的SCS小于PDSCH的SCS情况下，PDSCH的时域位置不早于PDSCH的时域限制位置，相较于相关技术中从开始接收PDCCH时便开始进行数据缓存，可以减少数据缓存量，降低能耗。
参照图3，示出了本公开一些实施例提供的PDSCH时域资源分配方法的步骤流程图。
本公开实施例的PDSCH时域资源分配方法包括以下步骤：
步骤301：依据PDSCH的SCS第二配置值与PDCCH的SCS第一配置值的确定第二中间值。
网络设备通过无线资源控制(Radio Resource Control，RRC)为终端配置了两个小区A与B，其中A是主小区即调度小区，B是辅小区即被调度小区，A跨载波调度B。网络侧配置了A小区的BWP上的PDCCH。A的SCS为μ PDCCH＝0，(即15kHz)，B的SCS为μ PDSCH＝2(即60kHz)。
μ PDCCH为第一配置值，μ PDSCH为第二配置值。第二中间值为依据第一配置值与第二配置值按照第二预设规则计算所得到的值。第二中间值可以为第二配置值与第二配置的差值，也可以为第一配置值与第二配置值差值的预设倍数，还可以为第一配置值与第二配置的加权平均值等，对于第一预设规则可以由本领域技术人员根据实际需求进行设置，本公开实施例中对此不做具体限制。
本公开实施例中以第二中间值为第二配置值与第一配置值的差值为例进行说明。本公开实施例中第二配置值为2，第一配置值为0，则第二配置值与第一配置值的差值则为2-0＝2，即第二中间值为2。
步骤302：依据终端上报的时域限制位置与第二中间值的对应关系，确定所述第二中间值对应的时域限制位置为PDSCH的时域限制位置。
本公开实施例中仍以时域限制位置为对时隙偏移K0的限制为例进行说明。K0≥L即时域限制位置。
时域限制位置与第二中间值的对应关系可由终端上报，由于第一配置值可以有多个，第二配置值也可以有多个，第一配置值与第二配置值的第二中间值也有多个，终端可以上报不同第二中间值与时域限制位置之间的对应关系。表3中示例性的给出了一组终端上报的时域限制位置与第二中间值的对应关系：
表3
μ PDSCH-μ PDCCH L(slot)
0 0
1 0
2 1
3 2
需要说明的是，表3中以solt单位为例进行说明，在具体实现过程中也 可以以OFDM符号为单位。
由于步骤301中所确定的第二中间值为2，通过表3可知，其对应的时域限制位置L为2。
在具体实现过程中，L也可以由终端通过能力上报，终端直接或者间接的方式通知网络其支持的时域限制位置L。
步骤303：终端不早于PDSCH的时域限制位置开始缓存或接收PDSCH。
在PDCCH的SCS小于PDSCH的SCS情况下，PDSCH的时域位置不早于PDSCH的时域限制位置。
终端在盲检测PDCCH时，可以只从时域限制位置指示的时间即K0＝L开始缓存数据，直到解调到DCI，根据DCI实际指示的时域位置K0接收PDSCH。

μ PDCCH为PDCCH的SCS的第一配置值，μ PDSCH为PDSCH的SCS的第二配置值，第一配置值为0，第二配置值为2。
本公开实施例中以时域限制位置为对时隙偏移K0的限制为例进行说明。
表4中示例性的给出了一组终端上报的配置值与处理时间的对应关系：

3 27
通过上述配置可确定的第一配置值为0，则通过表4可确定其对应的处理时间S为4。
步骤402：依据第一配置值、第二配置值以及第一处理时间，确定PDSCH的时域限制位置。
具体地，可以通过公式一确定PDSCH的时域限制位置：
Figure PCTCN2019095715-appb-000001
其中公式一中的M为时域限制位置，K0≥M，将第一配置值、第二配置值以及第一处理时间的值代入第一公式即可计算得到M的值。
步骤403：终端不早于PDSCH的时域限制位置开始缓存或接收PDSCH。
在PDCCH的SCS小于PDSCH的SCS情况下，PDSCH的时域位置不早于PDSCH的时域限制位置。
确定PDSCH的时域限制位置后，终端在盲检测PDCCH时，可以只从时域限制位置指示的时间即K0＝M开始缓存数据，直到解调到DCI，根据DCI实际指示的时域位置K0接收PDSCH。

本公开实施例中以基于PDCCH的SCS的第一配置值、PDSCH的SCS的第二配置值、参考OFDM符号以及PDCCH的时域长度确定PDSCH的时域限制位置为例进行说明。本公开实施例的PDSCH时域资源分配方法包括以下步骤：
步骤701：分别确定PDCCH的SCS的第一配置值以及PDSCH的SCS的第二配置值。
网络设备通过无线资源控制(Radio Resource Control，RRC)为终端配置了两个小区A与B，其中A是主小区即调度小区，B是辅小区即被调度小区，A跨载波调度B。网络侧配置了A小区的BWP上的PDCCH。A的SCS为μ PDCCH＝0，(即15kHz)，B的SCS为μ PDSCH＝2(即60kHz)。

步骤702：确定参考OFDM符号和PDCCH的时域长度。
参考OFDM符号可用P表示，时域长度可用D表示，本公开实施例中以P＝2，D＝3为例进行说明。P等于2则表示参考OFDM符号为第二个OFDM符号。
步骤703：基于第一配置值、第二配置值、参考OFDM符号以及时域长度，确定PDSCH的时域限制位置。

步骤802：将PDCCH所在的单位时间划分成预设数量各子单位时间。
在具体实现过程中，单位时间可以为slot，预设数量可以为4。当然并不局限于此，预设数量还可以设置为3或5等。
根据PDCCH的SCS，将PDCCH所在的slot分为4个sub-slot，sub-slot{k＝0、1、2、3}的边界符号编号S k依次为0、4、7、11。其中，sub-slot则为子单位时间。
步骤803：根据第一配置值、第二配置值以及PDCCH与各子单位时间边 界的相对位置，确定PDSCH的时域限制位置。
本公开实施例中以时域限制位置为对时隙偏移K0的限制为例进行说明。
在具体实现过程中，根据第一配置值、第二配置值以及PDCCH与各子单位时间边界的相对位置，确定PDSCH的时域限制位置的具体方式如下：
首先，通过PDCCH的最后一个符号的编号，确定PDCCH所在的sub-slot j
本公开实施例中以j＝1为例进行说明，j＝1则表示PDCCH在第一sub-slot上。
其次，根据PDCCH所在的sub-slot，确定最早的PDSCH的起始符号偏移O。本公开实施例中以O＝1为例进行说明。
再次，根据sub-slot j与偏移O，确定最早的PDSCH的起始符号P
k＝(j+O)＝2，
S k＝7,S 2对应的边界符号为7，因此S k＝7。
基于公式五
Figure PCTCN2019095715-appb-000005
确定早的PDSCH的起始符号P，即时域限制位置，K0≥P。
将μ PDCCH第一配置值，μ PDSCH第二配置值以及S k代入上述公式五得P值。
步骤804：终端不早于PDSCH的时域限制位置开始缓存或接收PDSCH。
在PDCCH的SCS小于PDSCH的SCS情况下，PDSCH的时域位置不早于PDSCH的时域限制位置。
