Because the base station can schedule any value in the time domain resource allocation list, the terminal device can only determine the time slot offset indicated by the DCI in the PDCCH when it detects the PDCCH.

Description

一种调度方法及装置
相关申请的交叉引用
本申请要求在2019年08月16日提交中国专利局、申请号为201910760931.4、申请名称为“一种调度方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域,尤其涉及一种调度方法及装置。
背景技术
在目前的第三代伙伴计划(the 3rd generation partnership project,3GPP)规定的协议中,基站进行下行调度之前,通过无线资源控制(radio resource control,RRC)信令向终端设备配置物理下行共享信道(physical downlink shared channel,PDSCH)的时域资源分配列表(Time Domain Resource Allocation List)。该时域资源分配列表中包含了物理下行控制信道(physical downlink control channel,PDCCH)与被调度的PDSCH之间的时间偏移,包括时隙偏移以及PDSCH在这个时隙内的起始符号和长度。比如时隙偏移可以配置为{0,1,2,3,4,5,6},当基站实际向终端设备调度PDSCH时,通过PDCCH中的下行控制信息(downlink control information,DCI)指示时域资源分配列表中一个时隙偏移,表示当前调度的PDSCH的时域位置相对于PDCCH的偏移值。如果DCI指示的时隙偏移为0,则表示PDSCH与PDCCH在同一个时隙。因为基站可以调度时域资源分配列表中的任一个值,终端设备只有检测到PDCCH才能确定PDCCH中的DCI指示的时隙偏移,因此终端设备在开始检测PDCCH时,总要假设PDCCH中的DCI指示的时隙偏移至少是时域资源分配列表中的最小值。如果时域资源分配列表中包含0,也就是基站有可能调度的PDSCH和PDCCH在同一个时隙,甚至PDSCH和PDCCH的起始符号都是相同的。对于下行调度而言,终端设备每次检测PDCCH的同时都要缓存PDSCH,因为在完成PDCCH检测之前不知道PDSCH的位置甚至不知道有没有PDSCH,这样会带来终端设备的功耗浪费。对于上行调度而言,类似的道理,终端设备不确定PDCCH调度的物理上行共享信道(physical uplink shared channel,PUSCH)的位置,这样就要求终端设备要尽快的检测出PDCCH,否则PDCCH和PUSCH在同一时隙时,终端设备来不及发送PUSCH,而较快的PDCCH检测速度同样会带来较大的功率消耗。
为了降低终端设备的功耗,目前的讨论中,在下行调度中,除了为终端设备配置PDSCH的时域资源分配列表之外,还为终端设备配置允许使用的最小时隙偏移值,该值可以记为最小K0(Minimum K0)。最小K0表示DCI中指示的时隙偏移的最小值为最小K0。当最小K0大于0时,终端设备可以确定PDSCH与PDCCH不在同一个时隙,在接收PDCCH时,可以不需要缓存太多的数据,同时不需要为了准备在PDCCH所处的时隙接收PDSCH而带来的功耗消耗,从而可以减少终端设备的功耗。基于同样的理由,在上行调度中,除了为终端设备配置PUSCH的时域资源分配列表之外,还为终端设备配置允许使用的最小时隙偏移值,该值可以记为最小K2(Minimum K2)。最小K2表示DCI中指示的时隙偏移 的最小值为最小K2。当最小K2大于0时,终端设备可以确定PUSCH与PDCCH不在同一个时隙,在接收PUSCH时,可以不需要为了准备在PDCCH所处的时隙发送PUSCH而带来的功耗消耗,从而可以减少终端设备的功耗。
目前的协议中,对于配置了最小K0、最小K2之后,如何根据实际情况更新最小K0、最小K2,还没有一个明确的解决方案。
发明内容
本申请实施例提供一种调度方法及装置,用以解决如何更新最小时隙偏移值的问题。
第一方面,本申请实施例提供一种调度方法,该方法包括:终端设备接收来自网络设备的第一消息;所述第一消息包括第一指示信息以及第二指示信息;所述第一指示信息用于指示是否更新第一偏移值;所述第二指示信息用于指示第二偏移值;所述终端设备利用所述第二偏移值更新所述第一偏移值。其中,所述第一偏移值为物理下行控制信道PDCCH与所述PDCCH调度的物理下行共享信道PDSCH之间的时间偏移的最小值;或者,所述第一偏移值为所述PDCCH与所述PDCCH调度的物理上行共享信道PUSCH之间的时间偏移的最小值;当所述第一指示信息指示更新所述第一偏移值时。
采用上述方法,网络设备通过第一指示信息来指示是否更新第一偏移值,使得终端设备能够及时根据第一指示信息更新第一偏移值,实现起来较为灵活。同时,当第一指示信息用于指示更新第一偏移值时,可以通过指示采用第一消息中携带的第二指示信息对第一偏移值进行更新,可以在不在第一消息中额外增加负载的情况下,实现更新第一偏移值。
在一种可能的设计中,所述第一消息包括第一字段,当所述第一字段包括的比特位的值为第一状态值时,所述第一指示信息指示更新所述第一偏移值;当所述第一字段包括的比特位的值为第二状态值时,所述第一指示信息指示不更新所述第一偏移值。

上述方法中,通过复用第一消息中已有的字段携带第二指示信息,实现起来更加灵活,而且不会对现有协议中第一消息的格式做修改,提高系统兼容性。
在一种可能的设计中,当所述第一指示信息指示更新所述第一偏移值时,所述方法还包括:所述终端设备根据所述第二偏移值确定第三偏移值;当所述第一偏移值为所述PDCCH与所述PDSCH之间的时间偏移的最小值时,所述终端设备将所述PDCCH与所述PUSCH之间的时间偏移的最小值更新为所述第三偏移值;或者,当所述第一偏移值为所述PDCCH与所述PUSCH之间的时间偏移的最小值时,所述终端设备将所述PDCCH与所述PDSCH之间的时间偏移的最小值更新为所述第三偏移值。
通过上述方法,通过第一指示信息同时更新PDCCH与PDSCH之间的时间偏移的最小值,以及PDCCH与PUSCH之间的时间偏移的最小值,实现通过一个指示信息同时更新两个时间偏移的最小值,可以提高系统效率,降低信令资源开销。
在一种可能的设计中,当所述第一指示信息指示更新所述第一偏移值时,所述方法还包括:当所述第二偏移值大于或等于所述第一偏移值时,所述终端设备根据所述第二偏移值接收所述PDSCH,或者根据所述第二偏移值发送所述PUSCH;或者,当所述第二偏移值小于所述第一偏移值时,所述终端设备确定所述PDCCH未调度所述PDSCH或者所述PUSCH。
在一种可能的设计中,所述方法还包括:当所述第一指示信息指示不更新所述第一偏移值时,所述终端设备根据所述第二偏移值接收所述PDSCH,或者根据所述第二偏移值发送所述PUSCH。
上述方法中,当所述第一指示信息指示不更新所述第一偏移值时,可以依然按照现有技术中的方法使用第二偏移值,提高系统兼容性。

参见图2,为本申请实施例提供的一种调度方法流程示意图。该方法包括:
步骤201:网络设备确定第一消息。
其中,所述第一消息包括第一指示信息以及第二指示信息;所述第一指示信息用于指示是否更新第一偏移值;所述第二指示信息用于指示第二偏移值。
所述第一偏移值为PDCCH与所述PDCCH调度的PDSCH之间的时间偏移的最小值; 或者,所述第一偏移值为所述PDCCH与所述PDCCH调度的PUSCH之间的时间偏移的最小值。
需要说明的是,本申请实施例中第一偏移值以及第二偏移值可以为时隙(slot)粒度的偏移值,也可以为符号(symbol)粒度的偏移值,还可以为其它粒度的偏移值,例如以秒为粒度,毫秒为粒度等。
举例来说,所述第一偏移值为PDCCH与所述PDCCH调度的PDSCH之间的时间偏移,以时隙粒度为例,示例性的,作为一个例子,指PDCCH所在的时隙(slot)和PDSCH所在slot的相对slot偏移值,例如PDCCH所在slot为n,PDCCH的子载波间隔为

所述PDCCH调度的PDSCH的子载波间隔为
Figure PCTCN2020109359-appb-000002
若第一偏移值为K0,则PDSCH所在的slot为
Figure PCTCN2020109359-appb-000003
其中K0以PDSCH的子载波间隔对应的slot为单位。
举例来说,所述第一偏移值为PDCCH与所述PDCCH调度的PUSCH之间的时间偏移,以时隙粒度为例,示例性的,作为一个例子,指PDCCH所在的slot和PUSCH所在slot的相对slot偏移值,例如PDCCH所在slot为n,PDCCH的子载波间隔为

所述PDCCH调度的PUSCH的子载波间隔为
Figure PCTCN2020109359-appb-000005
若第一偏移值为K2,则PUSCH所在的slot为
Figure PCTCN2020109359-appb-000006
其中K2以PUSCH的子载波间隔对应的slot为单位。
举例来说,所述第一偏移值为PDCCH与所述PDCCH调度的PDSCH之间的时间偏移,以符号粒度为例,示例性的,作为一个例子,指PDCCH的最后一个符号(symbol)和PDSCH的起始符号之间的符号相对偏移值,例如PDCCH的结束符号为n,PDCCH的子载波间隔为
Figure PCTCN2020109359-appb-000007
所述PDCCH调度的PDSCH的子载波间隔为
Figure PCTCN2020109359-appb-000008
若第一偏移值为m0,则PUSCH所在的起始符号为
Figure PCTCN2020109359-appb-000009
其中m0以PDSCH的子载波间隔对应的符号为单位。
举例来说,所述第一偏移值为PDCCH与所述PDCCH调度的PUSCH之间的时间偏移,以符号粒度为例,示例性的,作为一个例子,指PDCCH的最后一个符号(symbol)和PUSCH的起始符号之间的符号相对偏移值,例如PDCCH的结束符号为n,PDCCH的子载波间隔为
Figure PCTCN2020109359-appb-000010
所述PDCCH调度的PUSCH的子载波间隔为
Figure PCTCN2020109359-appb-000011
若第一偏移值为m2,则PUSCH所在的起始符号为
Figure PCTCN2020109359-appb-000012
其中m2以PUSCH的子载波间隔对应的符号为单位。
以上只是示例,其它情况可以参考此处的描述,在此不再赘述。
本申请实施例中,第一消息可以为承载于PDCCH中的DCI,也可以为其它类型的消 息,本申请实施例对此并不限定。
步骤202:网络设备向终端设备发送所述第一消息。
步骤203:终端设备接收来自网络设备的第一消息。
其中,所述第一消息包括第一指示信息以及第二指示信息。
步骤204:当所述第一指示信息指示更新所述第一偏移值时,所述终端设备利用所述第二偏移值更新所述第一偏移值。
另一方面,当第一指示信息指示不更新第一偏移值时,终端设备可以按照现有技术中的方法,根据第二偏移值进行数据传输。具体的,在第二偏移值为PDCCH与所述PDCCH调度的PDSCH之间的时间偏移的情况下,终端设备可以根据所述第二偏移值接收所述PDSCH。相应的,在第二偏移值为PDCCH与所述PDCCH调度的PUSCH之间的时间偏移的情况下,终端设备可以根据所述第二偏移值发送所述PUSCH。
通过上面的方法,网络设备通过第一指示信息来指示是否更新第一偏移值,从而使得终端设备能够及时确定是否更新第一偏移值,实现起来较为灵活。
本申请实施例中,第一指示信息、第二指示信息可以是显性的指示信息或者隐性的指示信息。其中,显性的指示信息指第一消息中包含字段用于第一指示信息或第二指示信息。隐性的指示值第一信息中不直接包含携带第一指示信息或第二指示信息的字段,而通过携带的其他信息间接的指示第一指示信息或者第二指示信息。第一指示信息、第二指示信息可以存在多种实现方式,下面将分别进行描述。
第一种可能的实现方式中,第一指示信息、第二指示信息均采用显性的方式指示。在该实现方式下,第一指示信息可以位于第一消息中的第一字段中,第二指示信息可以位于第一消息的第二字段中。
第一种可能的实现方式中,以第一消息为DCI为例,第一字段可以为DCI中已有的字段,也可以为未来的标准中新定义的字段,该新定义的字段可以专门用于承载第一指示信息,也可以用来承载其它信息,本申请实施例对此并不限定。
在该实现方式下,当所述第一字段包括的比特位的值为第一状态值时,所述第一指示信息指示更新所述第一偏移值;相应的,当所述第一字段包括的比特位的值为第二状态值时,所述第一指示信息指示不更新所述第一偏移值。第一状态值与第二状态值,均为预先约定的值。
举例来说,所述第一消息为DCI,第一字段为第一消息中的保留(reserved)字段,此处只是示例,第一字段还可以为未来的标准中新定义的字段。此时,可以使用第一字段中的1个比特承载第一指示信息,第一状态值可以为1,第二状态值可以为0。当网络设备将该比特的值设置为1时,表示需要更新第一偏移值;当网络设备将该比特的值设置为0时,表示不需要更新第一偏移值。当然,以上只是示例,还可以采用多个比特承载第一指示信息,第一状态值与第二状态值还可以存在其他取值,在此不再逐一举例说明。
第一种可能的实现方式中,第二字段可能存在至少两种实现方式,下面分别描述。
方式一:第二指示信息位于第一消息的第二字段中时,第二字段可以为第一消息中已有的字段,并可以保持第二字段在第一消息中原有的功能不变,即第二字段可以为第一消息中已有用于指示第二偏移值的字段。其中,第二指示信息指示的第二偏移值是网络设备从预设的偏移值集合中确定的一个值,网络设备具体如何确定,本申请在此不做限定。
举例来说,第一消息为DCI时,第二字段可以为时域资源分配(Time Domain Resource Allocation,TDRA)字段。此时,当第一偏移值为PDCCH与所述PDCCH调度的PDSCH之间的时间偏移的最小值时,TDRA字段中的第二指示信息指示的第二偏移值可以为PDCCH与所述PDCCH调度的PDSCH之间的时间偏移;当第一偏移值为PDCCH与所述PDCCH调度的PUSCH之间的时间偏移的最小值时,TDRA字段中的第二指示信息指示的第二偏移值可以为PDCCH与所述PDCCH调度的PUSCH之间的时间偏移。第一消息为其它消息时,第二字段的名称可能随之改变,在此不再逐一举例说明。
方式二:第二字段不再是第一消息中已有的用于指示第二偏移值的字段,而是可以对第一消息中已有的字段原有的功能进行重定义,从而复用第一消息中已有的字段。
结合第一指示信息,当第一指示信息指示更新第一偏移值时,第二字段中包括第二指示信息;当第一指示信息指示不更新第一偏移值时,第二字段中可以不包括第二指示信息,此时第二字段可以保留原来的功能不变。
举例来说,第一消息为DCI时,第二字段为第一消息中的带宽部分标识(bandwide part identity,BWP ID)字段。在该情况下,当第一指示信息指示更新第一偏移值时,BWP ID字段中包括第二指示信息指示的第二偏移值。当第一指示信息指示不更新第一偏移值时,BWP ID字段还可以按照现有技术中的方式,仍然用于指示终端设备的BWP的ID。
再举例来说,第一消息为DCI时,第二字段为第一消息中的保留(reserved)字段,此时第二指示信息指示的第二偏移值。当第一指示信息指示更新第一偏移值时,保留字段中包括第二指示信息指示的第二偏移值。当第一指示信息指示不更新第一偏移值时,保留字段还可以按照现有技术中的方式,仍然作为保留字段不变。
以上只是示例,第二字段也可能是DCI中的其它字段,在此不再逐一举例说明。
示例性的,第二字段还可以为未来的标准中,在第一消息中新定义的字段,在该情况下,第二指示信息指示的第二偏移值,可以专门用于更新第一偏移值。
在第一种可能的实现方式中,当第一指示信息指示更新第一偏移值时,还可能存在以下场景。
场景一:第二偏移值大于或等于第一偏移值。
现有技术中,第一偏移值是终端设备可以使用的最小值,而第二偏移值是终端设备实际使用的值,为此第二指示信息指示的第二偏移值一定大于或等于第一偏移值。因此,本申请实施例中,当终端设备确定第二偏移值大于或等于第一偏移值时,确定可以按照预先约定的方式使用第二偏移值。
举例来说,第一偏移值为PDCCH与PDSCH之间的时间偏移的最小值,当第二偏移值为PDCCH与所述PDCCH调度的PDSCH之间的时间偏移时,所述终端设备接收到PDCCH之后,可以根据所述第二偏移值接收所述PDSCH。终端设备具体如何接收PDSCH,可以参考现有技术中的描述,在此不再赘述。
再举例来说,第一偏移值为所述PDCCH与PUSCH之间的时间偏移的最小值,当第二偏移值为PDCCH与所述PDCCH调度的PUSCH之间的时间偏移时,所述终端设备接收到PDCCH之后,可以根据所述第二偏移值发送所述PUSCH。终端设备具体如何发送PUSCH,可以参考现有技术中的描述,在此不再赘述。
场景二:第二偏移值小于第一偏移值。
由于现有技术中,第二偏移值一定大于或等于第一偏移值。因此,本申请实施例中,当终端设备确定第二偏移值小于第一偏移值时,可以确定不需要根据第二偏移值接收PDSCH或者发送PUSCH。
因此,在该场景下,当第二偏移值为PDCCH与所述PDCCH调度的PDSCH之间的时间偏移,终端设备可以确定不需要接收所述PDSCH。相应的,当第二偏移值为PDCCH与所述PDCCH调度的PUSCH之间的时间偏移时,终端设备可以确定不需要发送所述PUSCH。
在第一种可能的实现方式中,当第一指示信息指示更新第一偏移值时,还可以根据第二偏移值确定第三偏移值。
其中,当所述第一偏移值为PDCCH与PDSCH之间的时间偏移的最小值时,第三偏移值用于更新PDCCH与所述PDCCH调度的PUSCH之间的时间偏移的最小值;当所述第一偏移值为所述PDCCH与所述PUSCH之间的时间偏移的最小值时,第三偏移值用于更新PDCCH与所述PDCCH调度的PDSCH之间的时间偏移的最小值。
终端设备可以根据第三偏移值对PDCCH与所述PDCCH调度的PUSCH之间的时间偏移的最小值进行更新,或者终端设备可以根据第三偏移值对PDCCH与所述PDCCH调度的PDSCH之间的时间偏移的最小值进行更新。
通过上述方法,通过第一指示信息同时更新PDCCH与PDSCH之间的时间偏移的最小值,以及PDCCH与PUSCH之间的时间偏移的最小值,实现通过一个指示信息同时更新两个时间偏移的最小值,可以提高系统效率,降低信令资源开销。
需要说明的是,如何根据第二偏移值确定第三偏移值存在多种实现方式。示例性的,第二偏移值与第三偏移值对应,第二偏移值与第三偏移值的对应关系是预先配置的。此时,当终端设备确定第二偏移值时,可以确定与所述第二偏移值对应的第三偏移值。
示例性的,第二偏移值与第三偏移值满足预设规则,所述预设规则是预先配置的。此时,当确定第二偏移值时,还可以根据所述预设规则与所述第二偏移值确定第三偏移值。例如,所述预设规则为:N mk2=N mk0+O mk2-O mk0
其中,N mk2表示第三偏移值;N mk0表示第二偏移值;O mk0表示第一偏移值;当所述第一偏移值为PDCCH与PDSCH之间的时间偏移的最小值时,O mk2表示所述PDCCH与PUSCH之间的时间偏移的最小值,当所述第一偏移值为PDCCH与PUSCH之间的时间偏移的最小值时,O mk2表示所述PDCCH与PDSCH之间的时间偏移的最小值。
当然,以上只是示例,预设规则还可以为其它形式,例如N mk2=N mk0*(O mk2/O mk0)等,在此不再逐一举例说明。
第二种可能的实现方式中,第一消息中也可以不直接携带第一指示信息,而是通过隐式的方式携带第一指示信息。
在该实现方式下,第一消息可以为DCI。目前,1个DCI对应的所有聚合等级对应的搜索空间的总和,可以称为搜索空间集合(search space set)。DCI和搜索空间集合的关系是预先配置的,网络设备发送DCI之后,终端设备需要在该DCI对应的搜索空间集合中检测DCI。
为此,可以通过发送第一消息所使用的搜索空间集合隐式的指示是否更新第一偏移值。具体的,当网络设备确定需要更新第一偏移值时,可以在预设搜索空间集合中发送第一消息。当终端设备在第一搜索空间集合中接收到第一消息,并确定第一搜索空间集合为预设搜索空间集合时,可以确定第一消息携带第一指示信息,且第一指示信息指示更新第一偏移值。
当网络设备确定不更新第一偏移值时,可以在预设搜索空间集合之外的搜索空间集合中发送第一消息。当终端设备在第一搜索空间集合中接收到第一消息,并确定第一搜索空间集合为预设搜索空间集合之外的搜索空间集合时,可以确定第一消息不携带第一指示信息,从而确定不需要指示更新第一偏移值。
在第三种可能的实现方式中,第二指示信息可以位于第一消息的第二字段中。第二字段可以为第一消息中已有的字段,也可以为新的字段,具体可以参考第一种可能的实现方式中的描述,在此不再赘述。作为一种例子,已有的字段为TDRA字段。
在第二种可能的实现方式中,当终端设备确定更新第一偏移值时,在某些情况下(例如当第二字段复用已有的TDRA字段时),还可能存在以下场景。
场景一:第二偏移值大于或等于第一偏移值。
在该场景下,当第二偏移值为PDCCH与所述PDCCH调度的PDSCH之间的时间偏移时,所述终端设备可以根据所述第二偏移值接收所述PDSCH。终端设备具体如何接收PDSCH,可以参考现有技术中的描述,在此不再赘述。
当第二偏移值为PDCCH与所述PDCCH调度的PUSCH之间的时间偏移时,所述终端设备可以根据所述第二偏移值发送所述PUSCH。终端设备具体如何发送PUSCH,可以参考现有技术中的描述,在此不再赘述。
场景二:第二偏移值小于第一偏移值。
在该场景下,当第二偏移值为PDCCH与所述PDCCH调度的PDSCH之间的时间偏移,或者为PDCCH与所述PDCCH调度的PUSCH之间的时间偏移时,终端设备可以确定所述PDCCH未调度所述PDSCH或者所述PUSCH,从而不接收所述PDSCH或者不发送所述PUSCH。
在第二种可能的实现方式中,当终端设备确定更新第一偏移值时,终端设备还可以根据第二偏移值确定第三偏移值,具体可以参考第一种可能的实现方式中的描述,在此不再赘述。
第三种可能的实现方式中,第一消息中也可以不直接携带第一指示信息,而是携带第三指示信息。第三指示信息用于指示PDCCH与所述PDCCH调度的PDSCH之间的时间偏移值或所述PDCCH与所述PDCCH调度的PUSCH之间的时间偏移值。
在该实现方式中,第一指示信息指示是否更新第一偏移值,是通过第三指示信息指示的值与第一偏移值的大小关系来实现。
举例来说,在该实现方式下,当所述第三指示信息指示的值小于所述第一偏移值时,所述第一指示信息指示更新所述第一偏移值;当所述第三指示信息指示的值大于或等于所述第一偏移值时,所述第一指示信息指示不更新所述第一偏移值。
需要说明的是,第三指示信息与前面描述的第二指示信息可以位于相同的字段中,也 可以位于不同的字段中。第三指示信息与第二指示信息位于相同的字段中时,第三指示信息与第二指示信息可以为同一个指示信息。
进一步可选的,现有技术中,在触发非周期信道状态信息参考信号(channel state information reference signal,CSI-RS)发送时,除了为终端设备配置非周期CSI-RS发送的时域资源分配列表之外,还为终端设备配置允许使用的最小时隙偏移值,该最小时隙偏移值可以记为最小A-CSI-RS triggering offset。最小A-CSI-RS triggering offset表示DCI中指示的非周期CSI-RS发送对应的时隙偏移的最小值。当最小A-CSI-RS triggering offset大于0时,终端设备可以确定非周期CSI-RS发送与PDCCH不在同一个时隙,可以不需要为了准备在PDCCH所处的时隙接收非周期CSI-RS而缓存信号,从而可以减少终端设备的功耗。
为此,本申请实施例中,第一消息中还可以包括第四指示信息,所述第四指示信息用于指示所述最小时隙偏移值。或者,第一消息中也可以不包括第四指示信息,也可以根据第二偏移值确定所述最小时隙偏移值,具体如何确定,可以参考根据第二偏移值确定第三偏移值中的描述,在此不再赘述。
