本申请实施例提供的一种配置PDCCH检测的方法,应用于网络设备,包括:
通过指示信号,为终端设备配置PDCCH检测的参数;
其中,所述PDCCH检测的参数,用于指示终端设备检测全部搜索空间中的部分特定搜索空间、和/或用于指示终端设备对搜索空间中的部分时域和/或部分频域进行检测。
具体的,参见图2,本申请提供的PDCCH检测方法,可以包括:
步骤201:获取终端设备的业务情况和/或负载情况;
步骤202:基于所述终端设备的业务情况和/或负载情况,确定针对所述终端设备的指示信号;
步骤203:通过指示信号,为终端设备配置PDCCH检测的参数;
其中,所述PDCCH检测的参数,用于指示终端设备检测全部搜索空间中的部分特定搜索空间、和/或用于指示终端设备对搜索空间中的部分时域和/或部分频域进行检测。
下面分别针对指示信号的不同类型进行说明:
第一种、
向终端设备发送第一指示信号,所述第一指示信号包含PDCCH检测的第一参数;其中,所述第一参数为搜索空间检测周期的倍数。
所述第一指示信号中,还包括:第二参数;其中,所述第二参数为指示所述终端设备检测的部分特定搜索空间对应的索引值。
检测周期是配置搜索空间的一个参数,用于表示搜索空间检测的周期,即X个时隙检测一次搜索空间。
具体的,可以在第一指示信号中携带第一参数P,所述第一参数P表示搜索空间的检测周期的倍数,典型的,P是大于或者大于等于1的整数。例如,终端的某个搜索空间的检测周期为5个时隙,在第一指示信号中携带的第一参数P=4,表示该搜索空间的检测周期调整为5*4=20个时隙。需要指出的是,第一参数P可以理解为检测周期的调整因子,其具体取值可以为大于1、或者小于1。
可选的,所述第一指示信号中,还包括:第二参数;其中,所述第二参数用于确定所述第一参数适用的搜索空间。
所述第二参数包括搜索空间的索引值;
所述第二参数用于确定所述第一参数适用的搜索空间,包括:所述第二参数适用于所述索引值对应的搜索空间。
在第一指示信号中可以同时携带第二参数,即搜索空间的索引(或一个位图,每个位对应一个搜索空间),此时第一参数P应用于该索引对应的搜索空间中。增加指示搜索空间。也就是说,当前假设有4个搜索空间,通过第二参数,可以指示对其中的第1、3个搜索空间进行搜索;结合第一参 数P调整针对每一个搜索空间的检测周期。
所述第二参数为比特位图,所述比特位图中的每一个比特对应一个搜索空间;
所述第二参数用于确定所述第一参数适用的搜索空间,包括:所述第二参数适用于该比特位图中为第一值的比特位对应的搜索空间。其中,所述第一值可以为1,也就是当比特位图中的某一个bit位设置为1时,表征对应的搜索空间为需要检测的搜索空间。
其中,假设第二参数通过位图的方式进行指示,那么可以为(1010),就可以表示针对其中的第一、三搜索空间进行检测,当然,还可以存在其他的指示方式,本实施例中不再进行穷举。
可选的,所述第二参数包括搜索空间的类别。通过预配置或者网络配置搜索空间的类别,如第一类搜索空间为用户专用搜索空间,第二类搜索空间为公用搜索空间,或者第一类搜索空间为检测周期小于10个时隙的搜索空间,第二类搜索空间为检测周期大于等于10个时隙的搜索空间,第二参数为一个比特,当该比特值为1时,表示所述第一参数适用于用户专用搜索空间,当该比特值为0时,表示所述第一参数适用于公用搜索空间。可选的,当所述第二参数为11,表示适用于所有的搜索空间。
可选的,所述第一参数应用于所述终端设备的全部搜索空间中;或者,所述第一参数应用于所述终端设备的第一类搜索空间中。第一类搜索空间可以是专有搜索空间,或者公共搜索空间,或者某个载波上的搜索空间,或者某个BWP上的搜索空间,或者是检测周期小于某个数值(例如10个时隙)的搜索空间。所述第一参数适用的第一类搜索空间,可以是网络配置的,或者是预配置的。比如,在第一指示信号中不携带搜索空间的索引,此时该第一参数P应用于该终端的所有的搜索空间中;或者该第一参数P应用于该终端的所有的UE专有搜索空间中,而公共搜索空间的参数不变。
也就是说,当第一指示信号中不包含第二参数时,可以仅利用第一参数进行检测,而第一参数可以应用于全部搜索空间中,或者,第一参数可以应用于终端设备的专用搜索空间中。还存在一种处理,可以为:通过网络侧配置指示终端设备不论当前是否接收到第二参数,仅采用第一参数进行检测,检测的可以为全部搜索空间,也可以为仅针对终端设备的专用搜索空间。
本实施例中,终端设备初始配置的至少一个搜索空间的检测周期,可以为:通过所述第一指示信号,为所述终端设备配置至少一个搜索空间对应的检测周期。也就是网络侧不仅通过第一指示信号对至少一个参数进行配置,还可以进行初始状态下每一个搜索空间的检测周期进行配置。比如,可以在第一指示信号中携带第二参数Q,所述第二参数Q用于配置某个或多个搜索空间的检测周期。
第二种、为了降低终端检测PDCCH的复杂度或者达到节能的目的,网络可以通过第二指示信号指示终端需要检测PDCCH的载波信息和/或BWP信息。
具体的,向终端设备发送第二指示信号,所述第二指示信号用于向终端设备指示需要检测的PDCCH的载波信息和/或BWP信息。
本方式中,网络设备还可以执行以下处理:为终端设备配置至少一个载波,在每个载波上配置至少一个带宽部分(BWP,Bandwidth part),在每个BWP上配置至少一个搜索空间。
具体的,所述第二指示信号中,包括有:至少一个载波索引、和/或、至少一个BWP索引。例如,网络为终端配置2个载波,在每个载波上配置了4个BWP,在每个BWP上配置了8个搜索空间,网络可以通过在PDCCH中携带载波索引和BWP索引,指示终端检测该载波上的该BWP上配置的所有的搜索空间。
进一步需要说明的是,所述第二指示信号中所包含的至少一个载波索引和/或至少一个BWP索引,为终端设备需要检测的PDCCH的载波信息和/或BWP信息。或者,所述第二指示信号中所包含的至少一个载波索引和/或至少一个BWP索引,为终端设备不需要检测的PDCCH的载波信息和/或BWP信息。也就是说,第二指示信号中携带的载波索引(或者BWP索引)用于指示终端检测该载波(BWP)上的搜索空间;或者,第二指示信号中携带的载波索引(或者BWP索引)用于指示终端检测除了该载波(BWP)的其他载波(BWP)上的搜索空间。
第三种、向终端设备发送第三指示信号;其中,所述第三指示信号包括聚合等级信息。
也就是说,向终端设备指示需要检测的搜索空间中的特定聚合等级对应的PDCCH。
也就是,通过第三指示信号指示终端需要检测的搜索空间中的某个聚合等级对应的PDCCH。
例如,新无线(NR,New Radio)系统的PDCCH支持聚合等级(Aggregation level)1、2、4、8、16,在PDCCH中携带聚合等级信息(例如AL=4),表示终端在所有的搜索空间中只需要检测聚合等级4的PDCCH。
第四种、
向终端设备发送第四指示信号;其中,所述第四指示信号包括控制资源集信息。
也就是,通过第四指示信号,指示所述终端设备对特定控制资源集信息所对应的搜索空间进行检测。
也就是说,网络为终端配置的搜索空间会对应到某个控制资源集,多个搜索空间可以对应相同的控制资源集,网络可以通过在第四指示信号中携带控制资源集的信息,指示终端只检测对应该控制资源集的搜索空间。
需要指出的是,前述四种指示信号可以结合在一起使用,比如可以使用前述四种指示信号中的至少之一来使用,具体的结合方式,本实施例中不再进行穷举。
需要说明的是,本实施例所述指示信号为PDCCH、或介质访问控制层(MAC,Media Access Control)控制元素(CE,Control Element)、或RRC信令。即前述第一指示信号、第二指示信号、第三指示信号、第四指示信号均可以通过PDCCH、或者MAC CE、或者RRC信令进行传输。
可选的,当所述指示信号为PDCCH时,若所述PDCCH承载的下行控制信息(DCI,Downlink Control Information)中的特定域为第二值,则确定所述PDCCH包括所述指示信号。
也就是说,当上述的第一、第二、第三、第四指示信号为PDCCH时,可以通过现有的DCI格式实现,例如,通过设置DCI中某些域为特殊值,用于表示该DCI为所述第一、第二、第三、第四指示信号。
进一步地,网络设备可以通过业务情况和/或网络负荷等情况,来确定前述指示信号。
比如,当终端设备的业务较少的时候,可以将终端设备的检测周期加大,可以通过第一参数对检测周期进行调节;或者,当网络负荷较大的时候,可以减少终端设备的检测次数。具体减少终端设备的检测次数的方式为通过前述四种指示信号中的一种或多种进行指示,这里不再进行穷举。
可见,通过采用上述方案,就能够控制终端设备仅检测部分搜索空间,和/或检测搜索空间中的部分时域和/或频域位置,如此,减少终端设备检测搜索空间的频次,从而对终端设备PDCCH的检测进行了优化,降低终端检测的复杂度或者节省功耗。

步骤301:接收网络侧发来的指示信号,基于所述指示信号获取PDCCH检测的参数;
步骤302:基于所述PDCCH检测的参数对PDCCH进行检测。

需要说明的是,本实施例所述指示信号为PDCCH、或MAC CE、或RRC信令。即前述第一指示信号、第二指示信号、第三指示信号、第四指示信号均可以通过PDCCH、或者MAC CE、或者RRC信令进行传输。
可选的,当所述指示信号为PDCCH时,若所述PDCCH承载的DCI中的特定域为第二值,则确定所述PDCCH包括所述指示信号。
也就是说,当上述的第一、第二、第三、第四指示信号为PDCCH时,可以通过现有的DCI格式实现,例如,通过设置DCI中某些域为特殊值,用于表示该DCI为所述第一、第二、第三、第四指示信号。
进一步地,网络设备可以通过业务情况和/或网络负荷等情况,来确定前述指示信号。
比如,当终端设备的业务较少的时候,可以将终端设备的检测周期加大,可以通过第一参数对检测周期进行调节;或者,当网络负荷较大的时候,可以减少终端设备的检测次数。具体减少终端设备的检测次数的方式为通过前述四种指示信号中的一种或多种进行指示,这里不再进行穷举。
可见,通过采用上述方案,就能够控制终端设备仅检测部分搜索空间,和/或检测搜索空间中的部分时域和/或频域位置,如此,减少终端设备检测搜索空间的频次,从而对终端设备PDCCH的检测进行了优化,降低终端检测的复杂度或者节省功耗。
本申请实施例提供的一种终端设备,如图4所示,包括:
第二通信单元41,用于接收网络侧发来的指示信号,基于所述指示信号获取PDCCH检测的参数;基于所述PDCCH检测的参数对PDCCH进行检测。
其中,所述PDCCH检测的参数,用于指示终端设备检测全部搜索空间中的部分特定搜索空间、和/或用于指示终端设备对搜索空间中的部分时域和/或部分频域进行检测。
下面分别针对指示信号的不同类型进行说明:
第一种、
第二通信单元41,用于接收网络侧发来的第一指示信号,所述第一指示信号包括第一参数;其中,所述第一参数为搜索空间检测周期的倍数。
检测周期是配置搜索空间的一个参数,用于表示搜索空间检测的周期,即X个时隙检测一次搜索空间。
具体的,可以在第一指示信号中携带第一参数P,所述第一参数P表示搜索空间的检测周期的倍数,典型的,P是大于或者大于等于1的整数。例如,终端的某个搜索空间的检测周期为5个时隙,在第一指示信号中携带的第一参数P=4,表示该搜索空间的检测周期调整为5*4=20个时隙。需要指出的是,第一参数P可以理解为检测周期的调整因子,其具体取值可以为大于1、或者小于1。
可选的,所述第一指示信号中,还包括:第二参数;其中,所述第二参数用于确定所述第一参数适用的搜索空间。
所述第二参数包括搜索空间的索引值;
所述第二参数适用于所述索引值对应的搜索空间。
在第一指示信号中可以同时携带第二参数,即搜索空间的索引(或一个位图,每个位对应一个搜索空间),此时该第一参数P应用于该索引对应的搜索空间中。增加指示搜索空间。也就是说,当前假设有4个搜索空间,通过第二参数,可以指示对其中的第1、3个搜索空间进行搜索;结合第一参数P调整针对每一个搜索空间的检测周期。
所述第二参数为比特位图,所述比特位图中的每一个比特对应一个搜索空间;
所述第二参数用于确定所述第一参数适用的搜索空间,包括:所述第二参数适用于该比特位图中为第一值的比特位对应的搜索空间。其中,所述第一值可以为1,也就是当比特位图中的某一个bit位设置为1时,表征对应的搜索空间为需要检测的搜索空间。
其中,假设第二参数通过位图的方式进行指示,那么可以为(1010),就可以表示针对其中的第一、三搜索空间进行检测,当然,还可以存在其他的指示方式,本实施例中不再进行穷举。
可选的,所述第一参数应用于所述终端设备的全部搜索空间中;或者,所述第一参数应用于所述终端设备的第一类搜索空间中。第一类搜索空间可以是专有搜索空间,或者公共搜索空间,或者某个载波上的搜索空间,或者某个BWP上的搜索空间。所述第一参数使用的第一类搜索空间,可以是网络配置的,或者是预配置的。比如,在第一指示信号中不携带搜索空间的索引,此时该第一参数P应用于该终端的所有的搜索空间中;或者该第一参数P应用于该终端的所有的UE专有搜索空间中,而公共搜索空间的参数不变。
也就是说,当第一指示信号中不包含第二参数时,可以仅利用第一参数进行检测,而第一参数可以应用于全部搜索空间中,或者,第一参数可以应用于终端设备的专用搜索空间中。还存在一种处理,可以为:通过网络侧配置指示终端设备不论当前是否接收到第二参数,仅采用第一参数进行检测,检测的可以为全部搜索空间,也可以为仅针对终端设备的专用搜索空间。
本实施例中,终端设备初始配置的至少一个搜索空间的检测周期,可以为:通过所述第一指示信号,为所述终端设备配置至少一个搜索空间对应的检测周期。也就是网络侧不仅通过第一指示信号对至少一个参数进行配置,还可以进行初始状态下每一个搜索空间的检测周期进行配置。比如,可以在第一指示信号中携带第二参数Q,所述第二参数Q用于配置某个或多个搜索空间的检测周期。
第二种、为了降低终端检测PDCCH的复杂度或者达到节能的目的,网络可以通过第二指示信号指示终端需要检测PDCCH的载波信息和/或BWP信息。
具体的,第二通信单元41,用于接收网络侧发来的第二指示信号,基于所述第二指示信号获取需要检测PDCCH的载波信息和/或BWP信息。
本方式中,网络设备还可以执行以下处理:为终端设备配置至少一个载波,在每个载波上配置至少一个带宽部分(BWP,Bandwidth part),在每个BWP上配置至少一个搜索空间。
具体的,所述第二指示信号中,包括有:至少一个载波索引、和/或、至少一个BWP索引。例如,网络为终端配置2个载波,在每个载波上配置了4个BWP,在每个BWP上配置了8个搜索空间,网络可以通过在PDCCH中携带载波索引和BWP索引,指示终端检测该载波上的该BWP上配 置的所有的搜索空间。
进一步需要说明的是,所述第二指示信号中所包含的至少一个载波索引和/或至少一个BWP索引,为终端设备需要检测的PDCCH的载波信息和/或BWP信息。或者,所述第二指示信号中所包含的至少一个载波索引和/或至少一个BWP索引,为终端设备不需要检测的PDCCH的载波信息和/或BWP信息。也就是说,第二指示信号中携带的载波索引(或者BWP索引)用于指示终端检测该载波(BWP)上的搜索空间;或者,第二指示信号中携带的载波索引(或者BWP索引)用于指示终端检测除了该载波(BWP)的其他载波(BWP)上的搜索空间。
第三种、第二通信单元41,用于接收网络侧发来的第三指示信号,所述第三指示信号包括聚合等级信息;基于所述聚合等级信息检测PDCCH。。
也就是,通过第三指示信号指示终端需要检测的搜索空间中的某个聚合等级对应的PDCCH。
例如,NR系统的PDCCH支持聚合等级(Aggregation level)1、2、4、8、16,在PDCCH中携带聚合等级信息(例如AL=4),表示终端在所有的搜索空间中只需要检测聚合等级4的PDCCH。
第四种、
第二通信单元41,用于接收网络侧发来的第四指示信号,所述第四指示信号包括控制资源集信息;检测关联到所述控制资源集的搜索空间中的PDCCH。
也就是说,网络为终端配置的搜索空间会对应到某个控制资源集,多个搜索空间可以对应相同的控制资源集,网络可以通过在第四指示信号中携带控制资源集的信息,指示终端只检测对应该控制资源集的搜索空间。
需要指出的是,前述四种指示信号可以结合在一起使用,比如可以使用前述四种指示信号中的至少之一来使用,具体的结合方式,本实施例中不再进行穷举。
需要说明的是,本实施例所述指示信号为PDCCH、或介质访问控制层(MAC,Media Access Control)控制元素(CE,Control Element)、或RRC信令。即前述第一指示信号、第二指示信号、第三指示信号、第四指示信号均可以通过PDCCH、或者MAC CE、或者RRC信令进行传输。
可选的,第二处理单元42,用于当所述指示信号为PDCCH时,若所述PDCCH承载的DCI中的特定域为第二值,则确定所述PDCCH包括所述指示信号。
也就是说,当上述的第一、第二、第三、第四指示信号为PDCCH时,可以通过现有的DCI格式实现,例如,通过设置DCI中某些域为特殊值,用于表示该DCI为所述第一、第二、第三、第四指示信号。
进一步地,网络设备可以通过业务情况和/或网络负荷等情况,来确定前述指示信号。
比如,当终端设备的业务较少的时候,可以将终端设备的检测周期加大,可以通过第一参数对检测周期进行调节;或者,当网络负荷较大的时候,可以减少终端设备的检测次数。具体减少终端设备的检测次数的方式为通过前述四种指示信号中的一种或多种进行指示,这里不再进行穷举。
可见,通过采用上述方案,就能够控制终端设备仅检测部分搜索空间,和/或检测搜索空间中的部分时域和/或频域位置,如此,减少终端设备检测搜索空间的频次,从而对终端设备PDCCH的检测进行了优化,降低终端检测的复杂度或者节省功耗。
