Description

一种通信方法、设备及装置
本申请要求在2018年8月10日提交国家知识产权局、申请号为201810912108.6、申请名称为“一种通信方法、设备及装置”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
本申请涉及通信技术领域,尤其涉及一种通信方法、设备及装置。
背景技术
在第五代移动通信系统(the 5 th generation,5G)系统中,已经确定了将终端设备的省电设计作为一个优化方向。在物理层,终端设备的能耗开销主要集中在候选物理下行控制信道(physical downlink control channel,PDCCH)的盲检上。简单来说可以理解为,基站在一段时间没有通过PDCCH向终端设备发送下行控制信令,而终端设备不确定基站是否会发送下行控制信令,因此终端设备需要持续一段时间对PDCCH进行盲检测,而这部分盲检的开销就成为了无用开销。如果能在保证PDCCH检测性能的前提下,减少这部分无用开销,则能够为终端设备提供更长时间的续航能力。
为此,在长期演进(long term evolution,LTE)LTE系统中,已经引入了非连续接收(discontinuous reception,DRX)机制,其中,当终端设备处于连接态(RRC connected)时,终端设备会使用DRX在连接态下的节能机制,即C-DRX(Connected-DRX),在C-DRX下,终端设备会周期性地盲检测候选PDCCH,在进行盲检时,终端设备能耗较高。
发明内容
本申请实施例提供一种通信方法、设备及装置,用于减小终端设备的功耗。
第一方面,提供第一种配置参数集合的方法,该方法包括:确定为终端设备配置的N个配置参数集合,所述N个配置参数集合中的每个配置参数集合包括检测候选下行控制信道的参数,N为大于或等于2的整数;向所述终端设备发送所述N个配置参数集合的信息,其中,所述N个配置参数集合中的每个配置参数集合包括以下参数中的至少一种:带宽区域,搜索空间的参数,检测候选下行控制信道的周期,控制资源集合的参数,以及,候选下行控制信道对应的时域资源集合。
该方法可由第一通信装置执行,第一通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。
第二方面,提供第二种配置参数集合的方法,该方法包括:接收N个配置参数集合的信息;根据所述N个配置参数集合的信息确定所述N个配置参数集合,其中,所述N个配置参数集合中的每个配置参数集合包括检测候选下行控制信道的参数,N为大于或等于2的整数,所述N个配置参数集合中的每个配置参数集合包括以下参数中的至少一种:带宽区域,搜索空间的参数,检测候选下行控制信道的周期,控制资源集合的参数,以及,候选下行控制信道对应的时域资源集合。
该方法可由第二通信装置执行,第二通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。
在本申请实施例中,可以为终端设备配置N个配置参数集合,由于N个配置参数集合包括的配置参数的值不完全相同,为终端设备处在N个配置参数集合中的两个配置参数集合时对应的检测候选PDCCH的能耗提供了不同的可能,从而可以通过使得终端设备切换配置参数集合而使得终端设备处于不同的检测候选PDCCH的能耗状态,减少终端设备始终处于最高检测候选PDCCH的能耗状态的几率,通过这种方式能够减小终端设备的检测候选PDCCH的能耗,延长终端设备的使用寿命。
例如,所述N个配置参数集合中的每个配置参数集合可以只包括这些参数中的至少一种,如,只包括检测候选下行控制信道的周期,或只包括带宽区域,等等。或者,所述N个配置参数集合中的每个配置参数集合可以包括这些参数中的至少两种。例如,所述N个配置参数集合中的每个配置参数集合可以包括搜索空间的参数和检测候选下行控制信道的周期等。
需要说明的是,每个配置参数集合中包括的参数是对应于该配置参数集合的。而且,不同的配置参数集合可以包括相同类型的参数,也可以包括的是不同类型的参数,本申请实施例对此并不限定。
在一个可能的设计中,所述方法还包括:在所述终端设备由不检测候选下行控制信道的时隙进入检测候选下行控制信道的时隙时,或,在第a个非连续接收状态周期中所述终端设备开始检测候选下行控制信道的一个或多个时隙,在第三配置参数集合对应的候选下行控制信道的资源上向所述终端设备发送下行控制信道,所述第三配置参数集合是所述N个配置参数集合中的特定的配置参数集合。相应的,所述方法还包括:在所述终端设备由不检测候选下行控制信道的时隙进入检测候选下行控制信道的时隙时,或,在第a个非连续接收状态周期中所述终端设备开始检测候选下行控制信道的一个或多个时隙,在第三配置参数集合对应的候选下行控制信道的资源上检测候选下行控制信道,所述第三配置参数集合是所述N个配置参数集合中的特定的配置参数集合。
如果终端设备要进行配置参数集合的切换,则很难保证终端设备和网络设备始终对于配置参数集合保持相同的认知,也就是很难保证终端设备和网络设备始终维持在相同的配置参数集合。鉴于此,为了让网络设备和终端设备能在发生认知错误后自动的修复,本申请实施例还提出,终端设备在由不检测候选下行控制信道的时隙进入检测候选下行控制信道的时隙时,或者说,在第a个DRX周期中终端设备开始检测候选PDCCH的一个或多个时隙,自动进入第三配置参数集合,网络设备也在第三配置参数集合对应的候选PDCCH的资源上发送PDCCH,这样,在每个DRX周期起始,网络设备和终端设备的配置参数集合始终是保持一致的。
在一个可能的设计中,向所述终端设备发送所述N个配置参数集合的信息,包括:向所述终端设备发送至少一个第一消息,所述至少一个第一消息用于指示所述N个配置参数集合,向所述终端设备发送至少一个第二消息,所述至少一个第二消息用于指示一个配置参数集合,所述一个配置参数集合与所述N个配置参数集合中的一个配置参数集合相同,其中,所述特定的配置参数集合为所述N个配置参数集合中的一个,或所述特定的配置参数集合为所述一个配置参数集合;或,向所述终端设备发送至少一个第一消息,所述至少一个第一消息用于指示所述N个配置参数集合中的N-1个配置参数集合,向所述终端设备发送至少一个第二消息,所述至少一个第二消息用于指示所述N个配置参数集合中除所述N-1个配置参数集合之外剩余的一个配置参数集合,其中,所述特定的配置参数集合为所 述N-1个配置参数集合中的一个,或所述特定的配置参数集合为所述一个配置参数集合;或,向所述终端设备发送至少一个第一消息,所述至少一个第一消息用于指示所述N个配置参数集合,其中,所述特定的配置参数集合为所述N个配置参数集合中的一个。
相应的,接收N个配置参数集合的信息,包括:接收至少一个第一消息,所述至少一个第一消息用于指示所述N个配置参数集合,接收至少一个第二消息,所述至少一个第二消息用于指示一个配置参数集合,所述一个配置参数集合与所述N个配置参数集合中的一个配置参数集合相同,其中,所述特定的配置参数集合为所述N个配置参数集合中的一个,或所述特定的配置参数集合为所述一个配置参数集合;或,接收至少一个第一消息,所述至少一个第一消息用于指示所述N个配置参数集合中的N-1个配置参数集合,接收至少一个第二消息,所述至少一个第二消息用于指示所述N个配置参数集合中除所述N-1个配置参数集合之外剩余的一个配置参数集合,其中,所述特定的配置参数集合为所述N-1个配置参数集合中的一个,或所述特定的配置参数集合为所述一个配置参数集合;或,接收至少一个第一消息,所述至少一个第一消息用于指示所述N个配置参数集合,其中,所述特定的配置参数集合为所述N个配置参数集合中的一个。
在一个可能的设计中,所述特定的配置参数集合为所述N个配置参数集合中的一个,所述至少一个第一消息还用于指示所述N个配置参数集合中的一个为所述特定的配置参数集合,或,所述特定的配置参数集合为所述N个配置参数集合中的默认的配置参数集合;或,所述特定的配置参数集合为所述N-1个配置参数集合中的一个,所述至少一个第一消息还用于指示所述N-1个配置参数集合中的一个为所述特定的配置参数集合,或,所述特定的配置参数集合为所述N-1个配置参数集合中的默认的配置参数集合。
网络设备可以通过至少一个第一消息和至少一个第二消息为终端设备配置N个配置参数集合,其中,通过至少一个第二消息为终端设备配置一个配置参数集合,通过至少一个第一消息为终端设备配置的配置参数集合中可以包括这一个配置参数集合,也就是通过至少一个第一消息为终端设备配置N个配置参数集合,使得终端设备更为明确网络设备的配置,或者,通过至少一个第一消息为终端设备配置的配置参数集合中也可以不包括这一个配置参数集合,也就是通过至少一个第一消息为终端设备配置N-1个配置参数集合,有助于减小第一消息的信息量。或者,网络设备也可以不发送第二消息,而是通过至少一个第一消息为终端设备配置N个配置参数集合,简化了配置过程。其中,第三配置参数集合可以是通过至少一个第一消息所配置的配置参数集合中的一个,或者也可以是通过至少一个第二消息所配置的配置参数集合。如果第三配置参数集合是通过至少一个第一消息所配置的配置参数集合中的一个,那么至少一个第一消息除了用于配置N个配置参数集合或N-1个配置参数集合之外,还用于指示,所配置的这些配置参数集合中的一个为第三配置参数集合;或者,如果第三配置参数集合是通过至少一个第一消息所配置的配置参数集合中的一个,那么也可以不通过至少一个第一消息来指示,而是通过默认或协议预定义的方式确定通过至少一个第一消息所配置的配置参数集合中的哪一个是第三配置参数集合,方式较为灵活。
作为一种示例,第三配置参数集合可以是N个配置参数集合中所对应的终端设备的检测候选PDCCH的能耗最高的配置参数集合。当然,本申请实施例也不限于此。
在一个可能的设计中,向所述终端设备发送所述N个配置参数集合的信息,包括:向所述终端设备发送至少一个第一消息,所述至少一个第一消息用于指示所述N个配置参数 集合,向所述终端设备发送至少一个第二消息,所述至少一个第二消息用于指示一个配置参数集合,所述一个配置参数集合与所述N个配置参数集合中的一个配置参数集合相同;或,向所述终端设备发送至少一个第一消息,所述至少一个第一消息用于指示所述N个配置参数集合中的N-1个配置参数集合,向所述终端设备发送至少一个第二消息,所述至少一个第二消息用于指示所述N个配置参数集合中除所述N-1个配置参数集合之外剩余的一个配置参数集合;或,向所述终端设备发送至少一个第一消息,所述至少一个第一消息用于指示所述N个配置参数集合。
相应的,接收所述N个配置参数集合的信息,包括:接收至少一个第一消息,所述至少一个第一消息用于指示所述N个配置参数集合,接收至少一个第二消息,所述至少一个第二消息用于指示一个配置参数集合,所述一个配置参数集合与所述N个配置参数集合中的一个配置参数集合相同;或,接收至少一个第一消息,所述至少一个第一消息用于指示所述N个配置参数集合中的N-1个配置参数集合,接收至少一个第二消息,所述至少一个第二消息用于指示所述N个配置参数集合中除所述N-1个配置参数集合之外剩余的一个配置参数集合;或,接收至少一个第一消息,所述至少一个第一消息用于指示所述N个配置参数集合。
关于这种设计的技术效果,可以参考对于前面的设计方式的技术效果的介绍。
在一个可能的设计中,所述N个配置参数集合中的第i个配置参数集合对应的候选下行控制信道的资源是第i-1个配置参数集合对应的候选下行控制信道的资源的子集,i为大于或等于1且小于或等于N的整数。
简单来讲,就是讲N个配置参数集合进行嵌套设置。在为终端设备配置了N个配置参数集合的情况下,网络设备可以通过PDCCH来指示终端设备进行配置参数集合的切换。那么,如果终端设备漏检了网络设备发送的用于指示终端设备进行配置参数集合切换的PDCCH,则终端设备继续按照原配置参数集合进行检测,而网络设备会按照新的配置参数集合发送PDCCH,从而会导致终端设备漏检网络设备发送的PDCCH。如果按照本申请实施例提供的方式,将N个配置参数集合进行了嵌套设置,且,规定网络设备在指示终端设备进行配置参数集合的切换时,只能按照配置参数集合所对应的终端设备对应的检测候选PDCCH的能耗从高到低的顺序进行切换,也就是,切换前的配置参数集合所对应的终端设备的检测候选PDCCH的能耗需要大于切换后的终端设备所对应的检测候选PDCCH的能耗,那么,根据嵌套设置的规则,切换后的配置参数集合所对应的候选PDCCH的资源就是切换前的配置参数集合所对应的候选PDCCH的资源的子集,那么,即使终端设备漏检了网络设备发送的用于指示终端设备进行配置参数集合切换的指令,终端设备继续按照原配置参数集合进行检测,网络设备按照新配置参数集合发送PDCCH,因为新的配置参数集合所对应的候选PDCCH的资源是原配置参数集合所对应的候选PDCCH的资源的子集,则网络设备在新的配置参数集合所对应的候选PDCCH的资源上所发送的PDCCH依然能够被终端设备检测到,从而减小了终端设备漏检PDCCH的可能性。
在一个可能的设计中,所述N个配置参数集合中的第i个配置参数集合对应的候选下行控制信道的资源是第i-1个配置参数集合对应的候选下行控制信道的资源的子集,包括以下至少一种:
所述N个配置参数集合中的每个配置参数集合包括检测候选下行控制信道的周期,所述第i个配置参数集合包括的检测候选下行控制信道的周期大于所述第i-1个配置参数集合 包括的检测候选下行控制信道的周期,且所述第i个配置参数集合包括的检测候选下行控制信道的周期是所述第i-1个配置参数集合包括的检测候选下行控制信道的周期的整数倍;
所述N个配置参数集合中的每个配置参数集合包括候选下行控制信道的时域资源集合的参数,所述第i个配置参数集合对应的候选下行控制信道的时域资源集合是所述第i-1个配置参数集合对应的候选下行控制信道的时域资源集合的子集;
所述N个配置参数集合中的每个配置参数集合包括搜索空间的参数,所述第i个配置参数集合对应的搜索空间的候选下行控制信道的集合是所述第i-1个配置参数集合对应的搜索空间的候选下行控制信道的集合的子集;
所述N个配置参数集合中的每个配置参数集合包括控制资源集合的参数,所述第i个配置参数集合对应的候选下行控制信道的控制资源集合是所述第i-1个配置参数集合对应的候选下行控制信道的控制资源集合的子集;
所述N个配置参数集合中的每个配置参数集合包括带宽区域,所述第i个配置参数集合对应的带宽区域所对应的候选下行控制信道的搜索空间是所述第i-1个配置参数集合对应的带宽区域所对应的候选下行控制信道的搜索空间的子集;以及,
所述N个配置参数集合中的每个配置参数集合包括带宽区域,所述第i个配置参数集合对应的带宽区域所对应的候选下行控制信道的控制资源集合是所述第i-1个配置参数集合对应的带宽区域所对应的候选下行控制信道的控制资源集合的子集。
其中,时域资源集合的参数例如可以指示时域资源集合的大小和位置等,搜索空间的参数例如指示搜索空间的候选PDCCH的集合。这几种参数只是示例,本申请实施例只是要使得N个配置参数集合中的第i个配置参数集合对应的候选PDCCH的资源是第i-1个配置参数集合对应的候选PDCCH的资源的子集,并不限制究竟通过哪些参数来实现,例如可以通过如上介绍的一种参数或多种参数来实现,还可以通过如上介绍的一种或多种参数、以及结合其他的参数来实现,或者也可以不通过如上介绍的参数,而是通过其他的参数来实现,本申请实施例均不做限制。
在一个可能的设计中,所述方法还包括:向所述终端设备发送第一下行控制信息,所述第一下行控制信息用于指示所述N个配置参数集合中的第一配置参数集合,其中,所述第一配置参数集合对应的候选下行控制信道的资源是所述N个配置参数集合中的第二配置参数集合对应的候选下行控制信道的资源的子集,所述第二配置参数集合是终端设备在检测所述第一下行控制信息时使用的配置参数集合,所述第一配置参数集合和所述第二配置参数集合是所述终端设备在同一非连续接收周期内使用的配置参数集合。相应的,所述方法还包括:接收第一下行控制信息,所述第一下行控制信息用于指示所述N个配置参数集合中的第一配置参数集合,其中,所述第一配置参数集合对应的候选下行控制信道的资源是所述N个配置参数集合中的第二配置参数集合对应的候选下行控制信道的资源的子集,所述第二配置参数集合是终端设备在检测所述第一下行控制信息时使用的配置参数集合,所述第一配置参数集合和所述第二配置参数集合是所述终端设备在同一非连续接收周期内使用的配置参数集合。
其中,例如终端设备在检测第一下行控制信息时使用的配置参数集合是N个配置参数集合中的第二配置参数集合,如果第一配置参数集合与第二配置参数集合不同,则可以理解为,第一下行控制信息是指示终端设备切换配置参数集合的信息,如果第一配置参数集合与第二配置参数集合相同,则可以理解为,第一下行控制信息是指示终端设备不切换配 置参数集合的信息。在通知信息通过第一下行控制信息实现的情况下,N个配置参数集合包括的各个配置参数集合需要按照前文所介绍的嵌套方式设置,且可以规定,网络设备在指示终端设备进行配置参数集合的切换时,需要使得切换后的配置参数集合对应的候选PDCCH的资源是切换前的配置参数集合对应的候选PDCCH的资源的子集,这样可以减小终端设备漏检PDCCH的可能性。
在一个可能的设计中,所述方法还包括:向终端设备组发送第二下行控制信息,所述第二下行控制信息包括至少一个指示信息,所述至少一个指示信息中的每个指示信息用于为所述终端设备组中的一个或多个终端设备指示所述N个配置参数集合中的配置参数集合。相应的,所述方法还包括:接收第二下行控制信息;根据所述第二下行控制信息包括的第一指示信息确定所述N个配置参数集合中的第二配置参数集合,其中,所述第二下行控制信息是基于终端设备组的下行控制信息,所述第一下行控制信息包括至少一个指示信息,所述至少一个指示信息中的每个指示信息用于为所述终端设备组中的一个或多个终端设备指示配置参数集合,所述终端设备属于所述终端设备组,所述第一指示信息对应于所述终端设备。
也就是,第二下行控制信息可以是基于终端设备组的下行控制信息,网络设备在发送第二下行控制信息时可以采用组播或广播的发送方式,该终端设备组中的终端设备接收第二下行控制信息后,根据第二下行控制信息包括的至少一个指示信息中与该终端设备对应的指示信息,就可以确定切换后的配置参数集合,或确定不切换配置参数集合。这样,通过发送一个第二下行控制信息就能指示多个终端设备的配置参数集合,有助于节省传输资源。
在一个可能的设计中,所述方法还包括:向所述终端设备发送MAC CE,所述MAC CE用于指示第一配置参数集合,其中,所述第一配置参数集合是所述N个配置参数集合中的一个。相应的,所述方法还包括:接收MAC CE,所述MAC CE用于指示第一配置参数集合,其中,所述第一配置参数集合是所述N个配置参数集合中的一个。
由于MAC CE是承载在PDSCH上,网络设备发送MAC CE后,终端设备会向网络设备回复物理层的应答信息,这种握手通信机制可以基本保证网络设备明确终端设备是否漏检了MAC CE,从而能够基本保证网络设备和终端设备按照相同的配置参数集合工作。因此,如果网络设备发送的是MAC CE,那么可以不必限制N个配置参数集合的设置方式,N个配置参数集合可以按照嵌套方式设置,或者也可以不按照嵌套方式设置,而是按照其他的方式设置。且,网络设备在指示终端设备进行配置参数集合的切换时,也不需要使得切换后的配置参数集合对应的候选PDCCH的资源是切换前的配置参数集合对应的候选PDCCH的资源的子集,也就是,无需限制切换后的配置参数集合,切换后的配置参数集合对应的候选PDCCH的资源可以是切换前的配置参数集合对应的候选PDCCH的资源的子集,或者切换后的配置参数集合对应的候选PDCCH的资源也可以不是切换前的配置参数集合对应的候选PDCCH的资源的子集,方式更为灵活。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚,下面将结合附图对本申请实 施例作进一步地详细描述。
以下,对本申请实施例中的部分用语进行解释说明,以便于本领域技术人员理解。
1)终端设备,包括向用户提供语音和/或数据连通性的设备,例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该终端设备可以经无线接入网(radio access network,RAN)与核心网进行通信,与RAN交换语音和/或数据。该终端设备可以包括用户设备(user equipment,UE)、无线终端设备、移动终端设备、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point,AP)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、或用户装备(user device)等。例如,可以包括移动电话(或称为“蜂窝”电话),具有移动终端设备的计算机,便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,智能穿戴式设备等。例如,个人通信业务(personal communication service,PCS)电话、无绳电话、会话发起协议(session initiation protocol,SIP)话机、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)、等设备。还包括受限设备,例如功耗较低的设备,或存储能力有限的设备,或计算能力有限的设备等。例如包括条码、射频识别(radio frequency identification,RFID)、传感器、全球定位系统(global positioning system,GPS)、激光扫描器等信息传感设备。
作为示例而非限定,在本申请实施例中,该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能头盔、智能首饰等。
2)网络设备,例如包括基站(例如,接入点),可以是指接入网中在空口通过一个或多个小区与无线终端设备通信的设备。网络设备可用于将收到的空中帧与网际协议(IP)分组进行相互转换,作为终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括IP网络。网络设备还可协调对空口的属性管理。例如,网络设备可以包括长期演进(long term evolution,LTE)系统或演进的LTE系统(LTE-Advanced,LTE-A)中的演进型基站(NodeB或eNB或e-NodeB,evolutional Node B),或者也可以包括第五代移动通信技术(fifth generation,5G)新无线(new radio,NR)系统中的下一代节点B(next generation node B,gNB)或者也可以包括云接入网(cloud radio access network,CloudRAN)系统中的集中式单元(centralized unit,CU)和分布式单元(distributed unit,DU),本申请实施例并不限定。
3)DRX,在DRX机制下,终端设备在一段时间里会停止监听PDCCH。DRX分两种:空闲(IDLE)DRX和C-DRX。
IDLE DRX,也就是终端设备处于空闲状态的非连续性接收,由于终端设备处于空闲状态时,已经没有无线资源控制(radio resource control,RRC)连接以及终端设备的专有资源,因此在IDLE DRX下终端设备主要是监听呼叫信道与广播信道,只要定义好固定的 周期,就可以达到非连续接收的目的。终端设备如果要监听用户数据信道,则需要从空闲状态先进入连接状态。
C-DRX,也就是终端设备处在RRC connected状态下的DRX,在C-DRX下,终端设备会周期性地盲检测候选PDCCH,在进行盲检时,终端设备一般都会按照最高检测候选PDCCH的能耗的配置进行检测,如果在一段时间内检测不到PDCCH,终端设备就会进入停止(OFF)状态,在OFF状态下终端设备停止检测候选PDCCH,以降低终端设备的检测候选PDCCH的能耗。
4)下行控制信道,例如为PDCCH,或者为增强的物理下行控制信道(enhanced physical downlink control channel,EPDCCH),或者可以是其他的下行控制信道。在本文中,以下行控制信道是PDCCH为例进行介绍,也就是,后文中所述的“PDCCH”均可替换为“下行控制信道”。
5)本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上,鉴于此,本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”,可理解为一个或多个,例如理解为一个、两个或更多个。例如,包括至少一个,是指包括一个、两个或更多个,而且不限制包括的是哪几个,例如,包括A、B和C中的至少一个,那么包括的可以是A、B、C、A和B、A和C、B和C、或A和B和C。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,字符“/”,如无特殊说明,一般表示前后关联对象是一种“或”的关系。
除非有相反的说明,本申请实施例提及“第一”、“第二”等序数词用于对多个对象进行区分,不用于限定多个对象的顺序、时序、优先级或者重要程度。
首先,介绍本申请实施例中涉及的技术特征。
在C-DRX下,终端设备会周期性地盲检测候选PDCCH,在进行盲检时,终端设备一般都会按照最高检测候选PDCCH的能耗的配置进行检测,如果在一段时间内检测不到PDCCH,终端设备就会进入OFF状态,在OFF状态下终端设备停止检测候选PDCCH,以降低终端设备的检测候选PDCCH的能耗。可见,终端设备在检测候选PDCCH的状态中,一般都会按照最高检测候选PDCCH的能耗的配置进行检测,导致检测候选PDCCH的能耗较大。另外,在C-DRX机制中,终端设备只具有两种状态,即检测候选PDCCH的状态与不检测候选PDCCH的状态(也就是OFF状态),这在一定程度上限制了终端设备平衡检测候选PDCCH的能耗与业务时延的灵活性。
鉴于此,提供本申请实施例的技术方案,在本申请实施例中,可以为终端设备配置N个配置参数集合,例如终端设备处在N个配置参数集合中的两个配置参数集合时对应的检测候选PDCCH的能耗可以是不同的,从而可以通过使得终端设备切换配置参数集合而使得终端设备处于不同的检测候选PDCCH的能耗状态,减少终端设备始终处于最高检测候选PDCCH的能耗状态的几率,通过这种方式能够减小终端设备的检测候选PDCCH的能耗,延长终端设备的使用寿命。
本申请实施例提供的技术方案可以应用于5G系统中,或者应用于LTE系统中,或者还可以应用于下一代移动通信系统或其他类似的通信系统,具体的不做限制。
下面介绍本申请实施例所应用的一种网络架构,请参考图1。
图1中包括网络设备和终端设备,终端设备与一个网络设备连接。当然图1中的终端 设备的数量只是举例,在实际应用中,网络设备可以为多个终端设备提供服务,网络设备可以为多个终端设备中的全部终端设备或者部分终端设备配置N个配置参数集合。
图1中的网络设备例如为接入网(access network,AN)设备,例如基站。其中,接入网设备在不同的系统对应不同的设备,例如在第四代移动通信技术(4G)系统中可以对应eNB,在第五代移动通信技术(5G)系统中对应5G中的接入网设备,例如gNB。
下面结合附图介绍本申请实施例提供的技术方案。
本申请实施例提供一种通信方法,请参见图2,为该方法的流程图。在下文的介绍过程中,以该方法应用于图1所示的网络架构为例,也就是,下文中所述的网络设备可以是图1所示的网络架构中的网络设备,下文中所述的终端设备可以是图1所示的网络架构中的终端设备。另外,该方法可由两个通信装置执行,这两个通信装置例如为第一通信装置和第二通信装置,其中,第一通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置,或者第一通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。对于第二通信装置也是同样,第二通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置,或者第二通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。且对于第一通信装置和第二通信装置的实现方式均不做限制,例如第一通信装置可以是网络设备,第二通信装置是终端设备,或者第一通信装置和第二通信装置都是网络设备,或者第一通信装置和第二通信装置都是终端设备,或者第一通信装置是网络设备,第二通信装置是能够支持终端设备实现该方法所需的功能的通信装置,等等。其中,网络设备例如为基站。
本实施例提出了为终端设备配置的N个配置参数集合。可以理解的,该N个配置参数集合包括的参数的类型可以是相同的,也可以是至少一种参数类型不同。但是该N个配置参数中包括的值是不完全相同的。例如,配置参数集合1中包括检测候选PDCCH的周期和BWP这两种参数,配置参数集合2中也包括检测候选PDCCH的周期和BWP这两种参数,其中,配置参数集合1中的检测候选PDCCH的周期的取值与配置参数集合2中的检测候选PDCCH的周期的取值不同,或者,配置参数集合1中的BWP的取值与配置参数集合2中的BWP的取值不同,或者,配置参数集合1中的检测候选PDCCH的周期的取值与配置参数集合2中的检测候选PDCCH的周期的取值不同,以及,配置参数集合1中的BWP的取值与配置参数集合2中的BWP的取值不同。
N个配置参数集合中的每个配置参数集合可以包括至少一种参数,例如,N个配置参数集合中的每个配置参数集合都包括检测候选PDCCH的参数,其中,N个配置参数集合中的每个配置参数集合所包括的检测候选PDCCH的参数,例如包括如下的至少一种:检测候选PDCCH的周期、候选PDCCH对应的时域资源集合、搜索空间的参数、控制资源集合的参数、以及带宽区域(band width part,BWP)。
当然,配置参数集合中还可以包括其他的检测候选PDCCH的参数,具体的不做限制。另外,N个配置参数集合中的不同的配置参数集合所包括的参数的种类可以是相同的,例如N个配置参数集合中的每个配置参数集合都包括检测候选PDCCH的周期、候选PDCCH对应的时域资源集合、搜索空间的参数、控制资源集合的参数、以及BWP这几种参数,或者,N个配置参数集合中的不同的配置参数集合所包括的参数的种类也可以有区别,但有交集,例如N个配置参数集合中的一个配置参数集合包括检测候选PDCCH的周期和候 选PDCCH对应的时域资源集合这两种参数,而N个配置参数集合中的另一个配置参数集合包括检测候选PDCCH的周期和搜索空间的参数这两种参数。
例如,所述N个配置参数集合中的每个配置参数集合可以只包括这些参数中的至少一种,如,只包括检测候选下行控制信道的周期,或只包括带宽区域,等等。或者,所述N个配置参数集合中的每个配置参数集合可以包括这些参数中的至少两种。例如,所述N个配置参数集合中的每个配置参数集合可以包括搜索空间的参数和检测候选下行控制信道的周期等。
需要说明的是,每个配置参数集合中包括的参数是对应于该配置参数集合的。而且,不同的配置参数集合可以包括相同类型的参数,也可以包括的是不同类型的参数,本申请实施例对此并不限定。
为了便于介绍,在下文中,以该方法由网络设备和终端设备执行为例,也就是,以第一通信装置是网络设备、第二通信装置是终端设备为例。
S21、网络设备确定为终端设备配置的N个配置参数集合,所述N个配置参数集合中的每个配置参数集合包括检测候选下行控制信道的参数,N为大于或等于2的整数。
S22、网络设备向终端设备发送N个配置参数集合的信息。
S23、终端设备根据所述N个配置参数集合的信息确定所述N个配置参数集合,其中,所述N个配置参数集合中的每个配置参数集合包括检测候选下行控制信道的参数,N为大于或等于2的整数。
网络设备在确定为终端设备配置的N个配置参数集合后,可以向终端设备发送N个配置参数集合的信息,从而为终端设备配置N个配置参数集合。
网络设备在向终端设备发送N个配置参数集合的信息时,可以通过不同的方式发送,下面分别介绍。
方式一、通过至少一个第一消息和至少一个第二消息发送,且通过至少一个第一消息和至少一个第二消息配置不同的配置参数集合。
例如,网络设备可以向终端设备发送至少一个第一消息,则终端设备接收来自网络设备的至少一个第一消息,至少一个第一消息用于指示N个配置参数集合,也就是,至少一个第一消息可以用于配置N个配置参数集合。第一消息的数量可以是一个或多个,例如第一消息的数量可以为M,从而通过M个第一消息配置一个配置参数集合,或者第一消息的数量也可以是一个,通过一个第一消息配置N个配置参数集合,等等。至少一个第一消息中的每个第一消息例如为RRC消息。M的数量可以大于N,也可以小于或等于N。
以及,网络设备可以向终端设备发送至少一个第二消息,则终端设备接收来自网络设备的至少一个第二消息,至少一个第二消息用于为终端设备配置一个配置参数集合。第二消息的数量可以是一个或多个。至少一个第二消息中的每个第二消息例如为RRC消息。
在方式一下,N个配置参数集合中可以包括至少一个第二消息所配置的配置参数集合。可以理解为,至少一个第二消息所配置的配置参数集合,是现有技术中网络设备会为终端设备配置的配置参数集合,在现有技术中,网络设备就只为终端设备配置这一个配置参数集合。而至少一个第一消息所配置的至少一个配置参数集合中的全部或部分,是本申请实施例中提出的,网络设备可以额外为终端设备配置的配置参数集合。那么,网络设备在通过第一消息为终端设备额外配置参数集合时,可以再将第二消息所配置的配置参数集合配置一次,使得终端设备更为明确网络设备一共配置了多少个配置参数集合。在这种情况下, 网络设备通过至少一个第一消息为终端设备配置了N个配置参数集合,N个配置参数集合里包括了网络设备通过至少一个第二消息为终端设备配置的一个配置参数集合,那么,除了现有技术里网络设备会为终端设备配置的这一个配置参数集合(也就是通过至少一个第二消息为终端设备配置的配置参数集合)之外,网络设备还额外为终端设备配置了N-1个配置参数集合,从而网络设备一共为终端设备配置了所述的N个配置参数集合。
如果是通过方式一发送N个配置参数集合的信息,那么对于网络设备来说,可以先确定通过至少一个第二消息指示的一个配置参数集合,再确定通过至少一个第一消息指示的N个配置参数集合的信息,在发送时,也可以先发送至少一个第二消息,再发送至少一个第一消息;或者,也可以先确定通过至少一个第一消息指示的N个配置参数集合,再确定通过至少一个第二消息指示的一个配置参数集合的信息,在发送时,也可以先发送至少一个第一消息,再发送至少一个第二消息;或者,也可以同时确定N个配置参数集合,在发送时,可以先发送至少一个第二消息,再发送至少一个第一消息,或者先发送至少一个第一消息,再发送至少一个第二消息,或者同时发送至少一个第一消息和至少一个第二消息。
方式二、通过至少一个第一消息和至少一个第二消息发送,且通过至少一个第一消息和至少一个第二消息所配置的配置参数集合有交集。
例如,网络设备可以向终端设备发送至少一个第一消息,则终端设备接收来自网络设备的至少一个第一消息,至少一个第一消息用于指示N个配置参数集合,也就是,至少一个第一消息可以用于配置N个配置参数集合。第一消息的数量可以是一个或多个,例如第一消息的数量可以为N,从而通过一个第一消息配置一个配置参数集合,或者第一消息的数量也可以是一个,通过一个第一消息配置N个配置参数集合,等等。至少一个第一消息中的每个第一消息例如为RRC消息。
以及,网络设备可以向终端设备发送至少一个第二消息,则终端设备接收来自网络设备的至少一个第二消息,至少一个第二消息用于为终端设备配置一个配置参数集合。第二消息的数量可以是一个或多个。至少一个第二消息中的每个第二消息例如为RRC消息。
在方式二下,N个配置参数集合中可以不包括至少一个第二消息配置的配置参数集合。可以理解为,至少一个第二消息所配置的配置参数集合,是现有技术中网络设备会为终端设备配置的配置参数集合,在现有技术中,网络设备就只为终端设备配置这一个配置参数集合。而至少一个第一消息所配置的至少一个配置参数集合,是本申请实施例中提出的,网络设备可以额外为终端设备配置的配置参数集合。网络设备可以通过至少一个第二消息为终端设备配置一个配置参数集合,以及通过至少一个第一消息为终端设备配置N-1个配置参数集合,在配置N-1个配置参数集合时,无需再次配置通过至少一个第二消息已经配置的配置参数集合,有助于节省传输资源。在这种情况下,网络设备通过至少一个第一消息为终端设备配置了N-1个配置参数集合,N-1个配置参数集合里不包括网络设备通过至少一个第二消息为终端设备配置的一个配置参数集合,那么,除了现有技术里网络设备会为终端设备配置的这一个配置参数集合(也就是通过至少一个第二消息为终端设备配置的配置参数集合)之外,网络设备还额外为终端设备配置了N-1个配置参数集合,从而网络设备一共为终端设备配置了N个配置参数集合。
如果是通过方式二发送N个配置参数集合的信息,那么对于网络设备来说,可以先确定通过至少一个第二消息指示的一个配置参数集合,再确定通过至少一个第一消息指示的N-1个配置参数集合的信息,在发送时,也可以先发送至少一个第二消息,再发送至少一 个第一消息;或者,也可以先确定通过至少一个第一消息指示的N-1个配置参数集合,再确定通过至少一个第二消息指示的一个配置参数集合的信息,在发送时,也可以先发送至少一个第一消息,再发送至少一个第二消息;或者,也可以同时确定N-1个配置参数集合,在发送时,可以先发送至少一个第二消息,再发送至少一个第一消息,或者先发送至少一个第一消息,再发送至少一个第二消息,或者同时发送至少一个第一消息和至少一个第二消息。
方式三、通过至少一个第一消息发送。
例如,网络设备可以向终端设备发送至少一个第一消息,则终端设备接收来自网络设备的至少一个第一消息,至少一个第一消息用于指示N个配置参数集合,也就是,至少一个第一消息可以用于配置N个配置参数集合。第一消息的数量可以是一个或多个,例如第一消息的数量可以为N,从而通过一个第一消息配置一个配置参数集合,或者第一消息的数量也可以是一个,通过一个第一消息配置N个配置参数集合,等等。至少一个第一消息中的每个第一消息例如为RRC消息。
在方式三下,网络设备不再向终端设备发送第二消息,N个配置参数集合就是通过至少一个第一消息配置的,方式较为简单。那么这N个配置参数集合中,可以包括现有技术中网络设备会为终端设备配置的配置参数集合,或者也可以不包括现有技术中网络设备会为终端设备配置的配置参数集合,而全都是本申请实施例重新为终端设备配置的配置参数集合。
对于网络设备究竟会采用如上的三种方式中的哪一种来为终端设备配置N个配置参数集合,可以由网络设备自行选择,或者可以通过协议预定义等,具体的不做限制。
在本申请实施例中,可能N个配置参数集合中的部分或全部配置参数集合所对应的候选PDCCH的资源是相同的,那么,终端设备处在这些配置参数集合时对应的检测候选PDCCH的检测候选PDCCH的能耗也是相近的。或者,N个配置参数集合中包括至少两个配置参数集合,这至少两个配置参数集合所对应的候选PDCCH的资源是不同的,那么,终端设备处在这至少两个配置参数集合时对应的检测候选PDCCH的检测候选PDCCH的能耗有较大差别的。或者,N个配置参数集合中的不同的配置参数集合所对应的候选PDCCH的资源均是不同的,那么,终端设备处在N个配置参数集合中的不同的配置参数集合时对应的检测候选PDCCH的检测候选PDCCH的能耗均有较大差别的。
在为终端设备配置了N个配置参数集合的情况下,在终端设备处于DRX周期内的检测候选PDCCH的状态时,网络设备可以指示终端设备进行配置参数集合的切换,如果N个配置参数集合中的部分或全部配置参数集合所对应的终端设备的检测候选PDCCH的检测候选PDCCH的能耗有较大差别,那么通过切换配置参数集合,就能够在一定程度上减小终端设备的检测候选PDCCH的能耗。在这种情况下,可能存在以下问题:例如网络设备会通过下行控制信息来指示终端设备进行配置参数集合的切换,那么,如果终端设备漏检了网络设备发送的用于指示终端设备进行配置参数集合切换的下行控制信息,则终端设备继续按照原配置参数集合进行检测,而网络设备会按照新的配置参数集合发送PDCCH,从而可能会导致终端设备漏检网络设备发送的PDCCH。例如,网络设备通过下行控制信息指示终端设备从检测候选PDCCH的周期1切换至检测候选PDCCH的周期2,检测候选PDCCH的周期1大于检测候选PDCCH的周期2,而终端设备漏检了该用于指示切换的PDCCH,则网络设备会在检测候选PDCCH的周期2对应的资源上发送PDCCH,但是终 端设备仍然在检测候选PDCCH的周期1对应的资源上检测候选PDCCH,导致终端设备漏检PDCCH。
考虑到以上问题,本申请实施例提出,可以将N个配置参数集合进行嵌套设置,所谓的嵌套设置,可以简单理解为,如果将N个配置参数集合按照终端设备对应的检测候选PDCCH能耗从大到小的顺序进行排序,那么位于该序列中的后一个配置参数集合所对应的候选PDCCH的资源,是位于该序列中的前一个配置参数集合所对应的候选PDCCH的资源的子集,优选的,可以是真子集。或者理解为,N个配置参数集合中包括的第i个配置参数集合对应的候选PDCCH的资源是第i-1个配置参数集合对应的候选PDCCH的资源的子集,优选的,可以是真子集,i为大于或等于1且小于或等于N的整数。需注意的是,这里的i,只是在将N个配置参数集合进行嵌套设置时所编写的序列号,并不是通过至少一个第一消息或至少一个第二消息所指示的N个配置参数集合的序列号,也跟至少一个第一消息或至少一个第二消息的发送时间或发送顺序等无关。也就是,i只代表N个配置参数集合之间的嵌套关系,不能做其他限制性解释。
如果将N个配置参数集合进行了嵌套设置,且,规定网络设备在指示终端设备进行配置参数集合的切换时,只能按照配置参数集合所对应的终端设备对应的检测候选PDCCH的能耗从高到低的顺序进行切换,也就是,切换前的配置参数集合所对应的终端设备的检测候选PDCCH的能耗需要大于切换后的终端设备所对应的检测候选PDCCH的能耗,那么,根据嵌套设置的规则,切换后的配置参数集合所对应的候选PDCCH的资源就是切换前的配置参数集合所对应的候选PDCCH的资源的子集,那么,即使终端设备漏检了网络设备发送的用于指示终端设备进行配置参数集合切换的指令,终端设备继续按照原配置参数集合进行检测,网络设备按照新配置参数集合发送PDCCH,因为新的配置参数集合所对应的候选PDCCH的资源是原配置参数集合所对应的候选PDCCH的资源的子集,则网络设备在新的配置参数集合所对应的候选PDCCH的资源上所发送的PDCCH依然能够被终端设备检测到,从而减小了终端设备漏检PDCCH的可能性。
在前文介绍了,配置参数集合可以包括至少一个参数,那么,配置参数集合所对应的候选PDCCH的资源,也就可以通过至少一个参数来定义。那么,要使得N个配置参数集合中包括的第i个配置参数集合对应的候选PDCCH的资源是第i-1个配置参数集合对应的候选PDCCH的资源的子集,就可以通过控制至少一个参数中的一个或多个来实现,也就是,N个配置参数集合中包括的第i个配置参数集合对应的候选PDCCH的资源是第i-1个配置参数集合对应的候选PDCCH的资源的子集,可以包括以下至少一种:
N个配置参数集合中的每个配置参数集合包括检测候选PDCCH的周期,第i个配置参数集合对应的检测候选PDCCH的周期大于第i-1个配置参数集合对应的检测候选PDCCH的周期,且第i个配置参数集合对应的检测候选PDCCH的周期是第i-1个配置参数集合对应的检测候选PDCCH的周期的整数倍;
N个配置参数集合中的每个配置参数集合包括候选PDCCH的时域资源集合的参数,第i个配置参数集合对应的检测候选PDCCH的时域资源集合是第i-1个配置参数集合对应的检测候选PDCCH的时域资源集合的子集;
所述N个配置参数集合中的每个配置参数集合包括搜索空间的参数,第i个配置参数集合对应的搜索空间的候选PDCCH的集合是第i-1个配置参数集合对应的搜索空间的候选PDCCH的集合的子集;
N个配置参数集合中的每个配置参数集合包括控制资源集合的参数,第i个配置参数集合对应的候选PDCCH的控制资源集合是第i-1个配置参数集合对应的候选PDCCH的控制资源集合的子集;
N个配置参数集合中的每个配置参数集合包括带宽区域,第i个配置参数集合对应的BWP所对应的搜索空间的候选PDCCH的集合是第i-1个配置参数集合对应的BWP所对应的搜索空间的候选PDCCH的集合的子集;以及,
N个配置参数集合中的每个配置参数集合包括带宽区域,第i个配置参数集合对应的BWP所对应的候选PDCCH的控制资源集合是第i-1个配置参数集合对应的BWP所对应的候选PDCCH的控制资源集合的子集。
对于如上几种参数,下面分别介绍。
1、第i个配置参数集合对应的检测候选PDCCH的周期大于第i-1个配置参数集合对应的检测候选PDCCH的周期,且第i个配置参数集合对应的检测候选PDCCH的周期是第i-1个配置参数集合对应的检测候选PDCCH的周期的整数倍。
对于检测候选PDCCH的周期的定义,可以图3为例。图3所示的部分包括在一个DRX周期内,因为一个DRX周期内还包括不检测候选PDCCH的状态,而本文主要关注的是一个DRX周期内的检测候选PDCCH的状态,因此图3只示出了一个DRX周期中属于检测候选PDCCH的状态的一部分。例如该DRX周期中包括2个检测候选PDCCH的周期,在一个检测候选PDCCH的周期内,例如是从第3个时隙(slot)开始检测,到第5个时隙结束,那么所谓的检测候选PDCCH的周期,就是两个检测候选PDCCH的周期中包括的第3个时隙之间的时间差,图3中标注的3、4、5所代表的矩形框就表示第3个时隙~第5个时隙,检测候选PDCCH的周期也就如图3所示。
本申请实施例规定,第i个配置参数集合对应的检测候选PDCCH的周期大于第i-1个配置参数集合对应的检测候选PDCCH的周期,这就表示,终端设备在处于第i个配置参数集合时,检测候选PDCCH的次数会等于或小于终端设备在处于第i-1个配置参数集合时检测候选PDCCH的次数,那么,终端设备在处于第i-1个配置参数集合时所对应的检测候选PDCCH的能耗可以等于或大于在处于第i-1个配置参数集合时所对应的检测候选PDCCH的能耗。另外,第i个配置参数集合对应的检测候选PDCCH的周期需要是第i-1个配置参数集合对应的检测候选PDCCH的周期的倍数,这是为了使得,第i-1个配置参数集合对应的检测位置中包括了第i个配置参数集合对应的检测位置。例如,可以设置第i-1个配置参数集合对应的检测候选PDCCH的周期为5ms,以及设置第i个配置参数集合对应的检测候选PDCCH的周期为10ms,那么,终端设备在处于第i-1个配置参数集合时,每隔5ms检测一次,例如检测位置包括1、6、11、16、21等,终端设备在处于第i个配置参数集合时,每隔10ms检测一次,例如检测位置包括1、11、21等,可见,第i-1个配置参数集合对应的检测位置中包括了第i个配置参数集合对应的检测位置,从而保证了第i个配置参数集合对应的候选PDCCH的资源是第i-1个配置参数集合对应的候选PDCCH的资源的子集或真子集。例如网络设备通过下行控制信息指示终端设备从检测候选PDCCH的周期为5ms的第i-1个配置参数集合切换为检测候选PDCCH的周期为10ms的第i个配置参数集合,或者说,网络设备是通过下行控制信息为终端设备指示了第i个配置参数集合的信息,而终端设备漏检了网络设备的指示,终端设备会继续以5ms作为检测候选PDCCH的周期,而网络设备会按照10ms的检测候选PDCCH的周期来发送PDCCH,根 据如上对于检测位置的介绍可知,终端设备依然会检测到网络设备所发送的PDCCH,从而减小了终端设备漏检PDCCH的可能性,提高了终端设备对于PDCCH的检测成功率。
2、第i个配置参数集合对应的检测候选PDCCH的时域资源集合是第i-1个配置参数集合对应的检测候选PDCCH的时域资源集合的子集。
因为对于一个配置参数集合包括的检测候选PDCCH的周期来说,其中的每个检测候选PDCCH的周期对应的检测候选PDCCH的时域资源集合都是相同的,因此第2点也可以具体化为,第i个配置参数集合对应的一个检测候选PDCCH的周期中的时域资源集合是第i-1个配置参数集合对应的同一个检测候选PDCCH的周期中的时域资源集合的子集,只要保证一个检测候选PDCCH的周期的时域资源集合满足该条件,就能保证第i个配置参数集合对应的检测候选PDCCH的时域资源集合是第i-1个配置参数集合对应的检测候选PDCCH的时域资源集合的子集,例如,可以是真子集。
关于配置参数集合对应的一个检测候选PDCCH的周期中的时域资源集合,可以根据检测候选PDCCH的周期、偏移量以及持续时长等参数来确定。例如可继续参考图3来理解。图3里包括2个检测候选PDCCH的周期,以其中的第一个检测候选PDCCH的周期为例,在第一个检测候选PDCCH的周期内,是从第3个时隙开始检测,到第5个时隙结束,也就是偏移量为2个时隙,持续时长为3个时隙,在该检测候选PDCCH的周期内的时域资源集合是时隙3~时隙5,而对于同一个配置参数集合对应的每个检测候选PDCCH的周期来说,时域资源集合都是相同的。当然,图3只是以时隙为粒度,在考虑时域资源集合时,粒度还可以更细,例如还可以以时域符号为粒度,也就是,配置参数集合对应的一个检测候选PDCCH的周期中的时域资源集合,可以根据检测候选PDCCH的周期、偏移量、持续时长以及时隙内的图样等参数来确定,时隙内的图样就是一个时隙内究竟在哪些时域符号上检测候选PDCCH。一种时域符号例如为正交频分复用(orthogonal frequency division multiplexing,OFDM)符号,或者也可以是其他的时域符号。
例如,在图3的基础上,以图3中的第一个检测候选PDCCH的周期为例,在第一个检测候选PDCCH的周期内,是从第3个时隙开始检测,到第5个时隙结束,而在每个时隙中,都是从第2个时域符号开始检测,到最后一个时域符号检测结束,例如一个时隙包括12个时域符号,那么,在该检测候选PDCCH的周期内的时域资源集合就是时隙3的时域符号1~时域符号11、时隙4的时域符号1~时域符号11、以及时隙5的时域符号1~时域符号11,同样,对于同一个配置参数集合对应的每个检测候选PDCCH的周期来说,时域资源集合都是相同的。
本申请实施例规定,第i个配置参数集合对应的一个检测候选PDCCH的周期中的时域资源集合是第i-1个配置参数集合对应的一个检测候选PDCCH的周期中的时域资源集合的子集,这就表示,终端设备在处于第i个配置参数集合时,检测候选PDCCH的时域资源会等于或少于终端设备在处于第i-1个配置参数集合时检测候选PDCCH的时域资源,那么,终端设备在处于第i-1个配置参数集合时所对应的检测候选PDCCH的能耗可以等于或大于在处于第i-1个配置参数集合时所对应的检测候选PDCCH的能耗。
例如,设置的第i-1个配置参数集合对应的一个检测候选PDCCH的周期中的时域资源集合可参考图3,是时隙3~时隙5,以及设置第i个配置参数集合对应的一个检测候选PDCCH的周期中的时域资源集合为时隙4和时隙5,可见,第i-1个配置参数集合对应的检测位置中包括了第i个配置参数集合对应的检测位置,从而保证了第i个配置参数集合 对应的候选PDCCH的资源是第i-1个配置参数集合对应的候选PDCCH的资源的子集。例如网络设备通过下行控制信息指示终端设备从第i-1个配置参数集合切换为第i个配置参数集合,或者说,网络设备是通过下行控制信息为终端设备指示了第i个配置参数集合的信息,第i-1个配置参数集合对应的一个检测候选PDCCH的周期中的时域资源集合为时隙3~时隙5,第i个配置参数集合对应的一个检测候选PDCCH的周期中的时域资源集合为时隙4和时隙5,而终端设备漏检了网络设备的指示,终端设备会继续以第i-1个配置参数集合来进行检测,而网络设备会以第i个配置参数集合来发送PDCCH,根据如上对于检测位置的介绍可知,终端设备依然会检测到网络设备所发送的PDCCH,从而减小了终端设备漏检PDCCH的可能性,提高了终端设备对于PDCCH的检测成功率。
或者,设置的第i-1个配置参数集合对应的一个检测候选PDCCH的周期中的时域资源集合可参考图3,是时隙3的时域符号1~时域符号11、时隙4的时域符号1~时域符号11、以及时隙5的时域符号1~时域符号11,以及设置第i个配置参数集合对应的一个检测候选PDCCH的周期中的时域资源集合为时隙3的时域符号2~时域符号11、时隙4的时域符号2~时域符号11、以及时隙5的时域符号2~时域符号11,可见,第i-1个配置参数集合对应的检测位置中依然包括了第i个配置参数集合对应的检测位置,从而保证了第i个配置参数集合对应的候选PDCCH的资源是第i-1个配置参数集合对应的候选PDCCH的资源的子集或真子集。如果网络设备通过下行控制信息指示终端设备从第i-1个配置参数集合切换为第i个配置参数集合,或者说,网络设备是通过下行控制信息为终端设备指示了第i个配置参数集合的信息,即使终端设备漏检了网络设备的指示,终端设备会继续以第i-1个配置参数集合来进行检测,而网络设备会以第i个配置参数集合来发送PDCCH,根据如上的介绍可知,终端设备依然会检测到网络设备所发送的PDCCH,从而减小了终端设备漏检PDCCH的可能性,提高了终端设备对于PDCCH的检测成功率。
3、第i个配置参数集合对应的搜索空间的候选PDCCH的集合是第i-1个配置参数集合对应的搜索空间的候选PDCCH的集合的子集。
其中,配置参数集合会对应相应的搜索空间,而搜索空间又会对应候选PDCCH的集合。
其中,配置参数集合对应的搜索空间的候选PDCCH的集合,还可以理解为是配置参数集合对应的至少一个聚合级别的候选PDCCH的数量。例如规定,终端设备在一个给定的时隙内的聚合级别为1个控制信道单元(control channel element,CCE)的候选PDCCH的数量为4M,那么为N个配置参数集合对应的聚合级别为1个控制信道单元的候选PDCCH的数量可以分别为4M、2M、M,或者终端设备在一个给定的时隙内的对聚合级别为2个CCE的候选PDCCH的数量为4P,那么为N个配置参数集合对应的聚合级别为1个控制信道单元的候选PDCCH的数量可以分别为4P、2P、P。如果以盲检测候选PDCCH次数来进行配置,那么需要注意的是,1个终端设备的全部搜索空间对应的候选PDCCH的数量即为这个终端设备的最大盲检测候选PDCCH次数。那么,为第i个配置参数集合对应的候选PDCCH的集合所配置的最大盲检测候选PDCCH次数所对应的搜索空间需要是为第i-1个配置参数集合对应的候选PDCCH的集合所配置的最大盲检测候选PDCCH次数所对应的搜索空间的子集,例如可以是真子集。因为,如果候选PDCCH的最大盲检测候选PDCCH次数为4M次,那么其中就包括了两个2M次的盲检测候选PDCCH次数,可以理解为包括了分别对应于两个2M次的盲检测候选PDCCH次数的搜索空间,也就是包 括了两个搜索空间,如果为第i-1个配置参数集合对应的候选PDCCH所配置的最大盲检测候选PDCCH次数为2M次,这2M次盲检测候选PDCCH次数对应的搜索空间为两个搜索空间里的第一个搜索空间,为第i-1个配置参数集合对应的候选PDCCH所配置的最大盲检测候选PDCCH次数为M次,而为第i-1个配置参数集合所配置的这M次盲检次数所对应的搜索空间如果是两个搜索空间里的第二个搜索空间,显然为第i个配置参数集合对应的候选PDCCH所配置的最大盲检测候选PDCCH次数所对应的搜索空间就不是为第i-1个配置参数集合对应的候选PDCCH所配置的最大盲检测候选PDCCH次数所对应的搜索空间的子集或真子集,在这种情况下,显然第i个配置参数集合对应的候选PDCCH的资源也就不是第i-1个配置参数集合对应的候选PDCCH的资源的子集或真子集,从而无法达到配置参数集合嵌套的目的。因此,如果为第i-1个配置参数集合对应的候选PDCCH所配置的最大盲检测候选PDCCH次数为2M次,这2M次盲检测候选PDCCH次数对应的搜索空间为两个搜索空间里的第一个搜索空间,为第i-1个配置参数集合对应的候选PDCCH所配置的最大盲检测候选PDCCH次数为M次,为第i-1个配置参数集合对应的候选PDCCH所配置的这M次盲检次数所对应的搜索空间也需要是两个搜索空间里的第一个搜索空间,这样才能保证第i个配置参数集合对应的候选PDCCH的资源是第i-1个配置参数集合对应的候选PDCCH的资源的子集或真子集,以达到配置参数集合嵌套的目的。
例如,网络设备通过下行控制信息指示终端设备从第i-1个配置参数集合切换为第i个配置参数集合,或者说,网络设备是通过下行控制信息为终端设备指示了第i个配置参数集合的信息,第i-1个配置参数集合对应的搜索空间为搜索空间1,第i个配置参数集合对应的搜索空间为搜索空间2,搜索空间2是搜索空间1的真子集,而终端设备漏检了网络设备的指示,终端设备会继续以第i-1个配置参数集合来进行检测,而网络设备会以第i个配置参数集合来发送PDCCH,根据如上介绍可知,终端设备会在搜索空间1里继续检测候选PDCCH,网络设备在搜索空间2里发送PDCCH,由于搜索空间2是搜索空间1的真子集,因此终端设备依然会检测到网络设备所发送的PDCCH,从而减小了终端设备漏检PDCCH的可能性,提高了终端设备对于PDCCH的检测成功率。
4、第i个配置参数集合对应的候选PDCCH的控制资源集合是第i-1个配置参数集合对应的候选PDCCH的控制资源集合的子集。
第3点中的搜索空间是逻辑上的概念,而在第4点里,从物理资源的角度进行描述。
一个配置参数集合对应的候选PDCCH可能对应一个或多个控制资源集合,或者说,可以为一个配置参数集合对应的候选PDCCH配置一个或多个控制资源集合,那么本申请实施例可以规定,第i个配置参数集合对应的候选PDCCH的控制资源集合是第i-1个配置参数集合对应的候选PDCCH的控制资源集合的子集,例如,可以是真子集。例如,为第i-1个配置参数集合对应的候选PDCCH配置的控制资源集合为控制资源集合1和控制资源集合2,为第i个配置参数集合对应的候选PDCCH配置的控制资源集合可以是控制资源集合1,或者是控制资源集合2,或者是控制资源集合1和控制资源集合2。
例如,网络设备通过下行控制信息指示终端设备从第i-1个配置参数集合切换为第i个配置参数集合,或者说,网络设备是通过下行控制信息为终端设备指示了第i个配置参数集合的信息,第i-1个配置参数集合对应的候选PDCCH的控制资源集合为控制资源集合1和控制资源集合2,第i个配置参数集合对应的候选PDCCH的控制资源集合例如为控制资源集合2,而终端设备漏检了网络设备的指示,终端设备会继续以第i-1个配置参数集合 来进行检测,而网络设备会以第i个配置参数集合来发送PDCCH,根据如上介绍可知,终端设备会在控制资源集合1和控制资源集合2里继续检测候选PDCCH,网络设备在控制资源集合2里发送PDCCH,由于终端设备的检测范围包括了控制资源集合2,因此终端设备依然会检测到网络设备所发送的PDCCH,从而减小了终端设备漏检PDCCH的可能性,提高了终端设备对于候选PDCCH的检测成功率。
5、第i个配置参数集合对应的BWP所对应的搜索空间的候选PDCCH的集合是第i-1个配置参数集合对应的BWP所对应的搜索空间的候选PDCCH的集合的子集。
对于BWP,可以不要求嵌套,也就是,可以不要求第i个配置参数集合对应的BWP是第i-1个配置参数集合对应的BWP的子集,但是终端设备在工作过程中可能会进行BWP的切换,例如终端设备开始工作在BWP1,采用的配置参数集合是第i-1个配置参数集合,网络设备在BWP1上通过下行控制信息指示终端设备从第i-1个配置参数集合切换到第i个配置参数集合,或者说,网络设备是通过下行控制信息为终端设备指示了第i个配置参数集合的信息,而终端设备进行了BWP切换,从BWP1切换到BWP2,可能因为进行BWP的切换,终端设备漏检了网络设备在BWP1上发送的用于指示切换配置参数集合的PDCCH,则终端设备在BWP2上会继续以第i-1个配置参数集合进行检测,而网络设备在BWP2上会按照第i个配置参数集合来发送PDCCH,可能导致漏检。因此,为了减小终端设备在这种情况下漏检PDCCH的可能性,可以配置第i个配置参数集合对应的BWP所对应的搜索空间的候选PDCCH的集合是第i-1个配置参数集合对应的BWP所对应的搜索空间的候选PDCCH的集合的子集,如果延续上例,就是配置第i个配置参数集合对应的BWP2所对应的搜索空间的候选PDCCH的集合是第i-1个配置参数集合对应的BWP1所对应的搜索空间的候选PDCCH的集合的子集,例如,可以是真子集。那么,即使终端设备漏检了网络设备发送的用于指示切换配置参数集合的PDCCH,终端设备在BWP2里会继续以第i-1个配置参数集合来进行检测候选PDCCH,而网络设备在BWP2里会以第i个配置参数集合来发送PDCCH,根据如上介绍可知,BWP2所对应的候选PDCCH的搜索空间是BWP1所对应的候选PDCCH的搜索空间的子集或真子集,因此终端设备依然会检测到网络设备所发送的PDCCH,从而减小了终端设备漏检PDCCH的可能性,提高了终端设备对于PDCCH的检测成功率。
其中,配置参数集合对应的搜索空间的候选PDCCH的集合,还可以理解为是配置参数集合对应的至少一个聚合级别的候选PDCCH的数量。例如规定,终端设备在一个给定的时隙内的聚合级别为1个CCE的候选PDCCH的数量为4M,那么为N个配置参数集合对应的聚合级别为1个控制信道单元的候选PDCCH的数量可以分别为4M、2M、M,或者终端设备在一个给定的时隙内的对聚合级别为2个CCE的候选PDCCH的数量为4P,那么为N个配置参数集合对应的聚合级别为1个控制信道单元的候选PDCCH的数量可以分别为4P、2P、P。如果以盲检测候选PDCCH次数来进行配置,那么需要注意的是,1个终端设备的全部搜索空间对应的候选PDCCH的数量即为这个终端设备的最大盲检测候选PDCCH次数。那么,为第i个配置参数集合对应的候选PDCCH的集合所配置的最大盲检测候选PDCCH次数所对应的搜索空间需要是为第i-1个配置参数集合对应的候选PDCCH的集合所配置的最大盲检测候选PDCCH次数所对应的搜索空间的子集,例如可以是真子集。关于这部分的具体介绍,可参考如上的第3点。
6、第i个配置参数集合对应的BWP所对应的候选PDCCH的控制资源集合是第i-1 个配置参数集合对应的BWP所对应的候选PDCCH的控制资源集合的子集。
根据第5点的介绍可知,虽然对于BWP不要求嵌套,但是为了减小终端设备漏检PDCCH的可能性,还是需要对BWP加以限制。在第5点中,是配置第i个配置参数集合对应的BWP所对应的搜索空间的候选PDCCH的集合的是第i-1个配置参数集合对应的BWP所对应的搜索空间的候选PDCCH的集合的子集,而在第6点中,就选择配置第i个配置参数集合对应的BWP所对应的候选PDCCH的控制资源集合是第i-1个配置参数集合对应的BWP所对应的候选PDCCH的控制资源集合的子集,例如,可以是真子集。
例如,终端设备开始工作在BWP1,采用的配置参数集合是第i-1个配置参数集合,网络设备在BWP1上通过下行控制信息指示终端设备从第i-1个配置参数集合切换到第i个配置参数集合,或者说,网络设备是通过下行控制信息为终端设备指示了第i个配置参数集合的信息,而终端设备进行了BWP切换,从BWP1切换到BWP2,可能因为进行BWP的切换,终端设备漏检了网络设备在BWP1上发送的用于指示切换配置参数集合的PDCCH,则终端设备在BWP2上会继续以第i-1个配置参数集合进行检测候选PDCCH,而网络设备在BWP2上会按照第i个配置参数集合来发送PDCCH。而本申请实施例配置了,第i个配置参数集合对应的BWP2所对应的候选PDCCH的控制资源集合是第i-1个配置参数集合对应的BWP1所对应的候选PDCCH的控制资源集合的子集或真子集,那么,即使终端设备漏检了网络设备发送的用于指示切换配置参数集合的PDCCH,终端设备在BWP2里会继续以第i-1个配置参数集合来进行检测候选PDCCH,而网络设备在BWP2里会以第i个配置参数集合来发送PDCCH,根据如上介绍可知,BWP2所对应的候选PDCCH的控制资源集合是BWP1所对应的候选PDCCH的控制资源集合的子集,因此终端设备依然会检测到网络设备所发送的PDCCH,从而减小了终端设备漏检PDCCH的可能性,提高了终端设备对于PDCCH的检测成功率。
如上对几种参数进行了介绍,需注意的是,如上的介绍只是示例,本申请实施例只是要使得N个配置参数集合中的第i个配置参数集合对应的候选PDCCH的资源是第i-1个配置参数集合对应的候选PDCCH的资源的子集,并不限制究竟通过哪些参数来实现,例如可以通过如上介绍的一种参数或多种参数来实现,还可以通过如上介绍的一种或多种参数、以及结合其他的参数来实现,或者也可以不通过如上介绍的参数,而是通过其他的参数来实现,本申请实施例均不做限制。
S24、网络设备发送通知信息,则终端设备接收通知信息,所述通知信息用于指示配置参数集合。
在本申请实施例中,通知信息可以有不同的实现方式。
作为通知信息的第一种实现方式,通知信息可以通过下行控制信息实现,一种下行控制信息例如为(downlink control information,DCI)。例如,通知信息可实现为第一下行控制信息,第一下行控制信息用于指示N个配置参数集合中的第一配置参数集合,其中,例如终端设备在检测第一下行控制信息时使用的配置参数集合是N个配置参数集合中的第二配置参数集合,如果第一配置参数集合与第二配置参数集合不同,则可以理解为,第一下行控制信息是指示终端设备切换配置参数集合的信息,如果第一配置参数集合与第二配置参数集合相同,则可以理解为,第一下行控制信息是指示终端设备不切换配置参数集合的信息。
在通知信息通过第一下行控制信息实现的情况下,N个配置参数集合包括的各个配置 参数集合需要根据前文的介绍,按照嵌套方式设置,且可以规定,网络设备在指示终端设备进行配置参数集合的切换时,需要使得切换后的配置参数集合对应的候选PDCCH的资源是切换前的配置参数集合对应的候选PDCCH的资源的子集,也可以理解为,需要使得切换后的配置参数集合对应的终端设备的检测候选PDCCH的能耗小于切换前的配置参数集合对应的终端设备的检测候选PDCCH的能耗。如果将N个配置参数集合包括的各个配置参数集合按照对应的终端设备的检测候选PDCCH的能耗从大到小的顺序排序,也可以理解为,切换后的配置参数集合在该序列里的位置需要位于切换前的配置参数集合在该序列里的位置之后,但本申请实施例不限制切换后的配置参数集合与切换前的配置参数集合在该序列里的间隔,例如在该序列里,切换后的配置参数集合与切换前的配置参数集合是相邻的配置参数集合,或者在该序列里,切换后的配置参数集合与切换前的配置参数集合之间还间隔了其他的配置参数集合。
例如,第一下行控制信息可以是终端设备专用的下行控制信息,也就是基于终端设备的下行控制信息,第一下行控制信息中可以包括一个或多个比特,通过这一个或多个比特指示配置参数集合。那么,网络设备在发送第一下行控制信息时可以采用单播的方式,将第一下行控制信息发送给相应的终端设备,从而该终端设备根据第一下行控制信息确定切换后的配置参数集合,或确定不切换配置参数集合。通过终端设备专用的下行控制信息来指示终端设备的配置参数集合,可以使得指示更为明确。
或者,在通知信息通过下行控制信息实现的情况下,例如,通知信息还可以实现为第二下行控制信息。
第二下行控制信息可以是基于终端设备组的下行控制信息,例如第二下行控制信息可以包括至少一个指示信息,其中的每个指示信息用于指示该终端设备组中的一个或多个终端设备的配置参数集合。例如,至少一个指示信息中的每个指示信息可用于指示一个终端设备的配置参数集合,例如至少一个指示信息中的一个指示信息可用于为一个终端设备指示配置参数集合的索引。或者,至少一个指示信息中的每个指示信息可用于指示多个终端设备的配置参数集合,以至少一个指示信息中的一个指示信息指示三个终端设备的配置参数集合为例,当至少一个指示信息中的一个指示信息指示的配置参数集合的索引为3时,则指示对应的三个终端设备的配置参数集合的索引都为3。其中,如果至少一个指示信息中的每个指示信息用于指示多个终端设备的配置参数集合,则至少一个指示信息中不同的指示信息所指示的终端设备的数量可以是相同的,例如每个指示信息都指示2个终端设备的配置参数集合,或者,至少一个指示信息中不同的指示信息所指示的终端设备的数量也可以是不同的,例如,至少一个指示信息中有一个指示信息所指示的终端设备的数量为2,还有一个指示信息所指示的终端设备的数量为3。本申请实施例对于至少一个指示信息中每个指示信息所指示的终端设备的数量不做限制。
该终端设备组中的终端设备事先知道至少一个指示信息中的哪个指示信息是该终端设备所对应的,因此,网络设备在发送第二下行控制信息时可以采用组播或广播的发送方式,该终端设备组中的终端设备接收第二下行控制信息后,根据第二下行控制信息包括的至少一个指示信息中与该终端设备对应的指示信息,就可以确定切换后的配置参数集合,或确定不切换配置参数集合。例如,终端设备组中的一个终端设备对应于第二下行控制信息包括的至少一个指示信息中的第一指示信息,则该终端设备接收第二下行控制信息后,根据第一指示信息就可以确定切换后的配置参数集合,或确定不切换配置参数集合。这样, 通过发送一个第二下行控制信息就能指示多个终端设备的配置参数集合,有助于节省传输资源。
例如,终端设备组包括P个终端设备,基于终端设备组的第二下行控制信息可以包含K*P个比特信息位,K和P均为正整数,K*P个比特信息位能够用于指示P个终端设备的配置参数集合。如果K=1,则每个终端设备对应第二下行控制信息中的1个比特信息位,该1个比特信息位如果取值为“1”,表示指示该终端设备工作在N个配置参数集合序列中的下一个配置参数集合,该1个比特信息位如果取值为“0”,则表示该终端设备的配置参数集合不变。也就是,这1个比特信息位没有明确指示具体的配置参数集合的信息,如果要切换,则只是告知终端设备按照N个配置参数集合嵌套设置后构成的序列中的顺序进行切换,例如是按照从终端设备的高检测候选PDCCH的能耗到低检测候选PDCCH的能耗的顺序切换。例如,网络设备为终端设备配置的N个配置参数集合中包括4种配置参数集合,分别为配置参数集合1~配置参数集合4,按照配置参数集合对应的终端设备的检测候选PDCCH的能耗排序,该序列为配置参数集合1>配置参数集合2>配置参数集合3>配置参数集合4。当终端设备工作在配置参数集合1时,如果接收了第二下行控制信息,该第二下行控制信息中与该终端设备对应的指示信息的取值为“1”,则该终端设备就确定要从配置参数集合1切换为配置参数集合2,而如果该第二下行控制信息中与该终端设备对应的指示信息的取值为“0”,则该终端设备确定维持配置参数集合1不变。这里是以K=1为例,如果K>1,则每个终端设备可以对应第二下行控制信息中的K个比特信息位,K个比特信息位最多可以对应2 K种配置参数集合,从而可以使得网络设备的指示更为灵活。
在通知信息通过第二下行控制信息实现的情况下,需要使得切换后的配置参数集合对应的候选PDCCH的资源是切换前的配置参数集合对应的候选PDCCH的资源的子集,例如切换后的配置参数集合为第一配置参数集合,切换前的配置参数集合为第二配置参数集合,也就是,需要使得第一配置参数集合对应的候选PDCCH的资源是第二配置参数集合对应的候选PDCCH的资源的子集,那么第一配置参数集合和第二配置参数集合的组合就不会包含如下的一种或多种:
第二配置参数集合对应的检测候选PDCCH的周期大于第一配置参数集合对应的检测候选下行控制信道的周期,或,第一配置参数集合对应的检测候选PDCCH的周期不是第二配置参数集合对应的检测候选PDCCH的周期的整数倍,或,第二配置参数集合对应的检测候选PDCCH的周期大于第一配置参数集合对应的检测候选下行控制信道的周期,且第一配置参数集合对应的检测候选PDCCH的周期不是第二配置参数集合对应的检测候选PDCCH的周期的整数倍;
第一配置参数集合对应的检测候选PDCCH的时域资源集合不是第二配置参数集合对应的一个检测候选PDCCH的时域资源集合的子集;
第一配置参数集合对应的搜索空间的候选PDCCH的集合不是第二配置参数集合对应的搜索空间的候选PDCCH集合的子集;
第一配置参数集合对应的候选PDCCH的控制资源集合不是第二配置参数集合对应的PDCCH的控制资源集合的子集;
第一配置参数集合对应的带宽区域所对应的搜索空间的候选PDCCH的集合不是第二配置参数集合对应的带宽区域所对应的搜索空间的候选PDCCH的集合的子集;以及,
第一配置参数集合对应的带宽区域所对应的候选PDCCH的控制资源集合不是第二配 置参数集合对应的带宽区域所对应的候选PDCCH的控制资源集合的子集。
如上的几种情况,都不满足切换后的配置参数集合对应的候选PDCCH的资源是切换前的配置参数集合对应的候选PDCCH的资源的子集或真子集这个条件,因此如果通知信息通过第一下行控制信息实现,则第一配置参数集合和第二配置参数集合的组合不包括如上的一种或多种情况。
作为通知信息的第二种实现方式,通知信息可以通过承载在媒体接入控制控制元素(media access control control element,MAC CE)中,或者说,通知信息通过MAC CE实现。例如,通知信息可以由下行数据的MAC CE字段承载,该MAC CE字段可以位于下行数据的MAC层包头中。由于MAC CE是承载在物理下行共享信道(physical downlink shared channel,PDSCH)上,网络设备发送MAC CE后,终端设备会向网络设备回复物理层的应答信息,这种握手通信机制可以基本保证网络设备明确终端设备是否漏检了MAC CE,从而能够基本保证网络设备和终端设备按照相同的配置参数集合工作。因此,如果通知信息承载在MAC CE中,那么可以不必限制N个配置参数集合的设置方式,N个配置参数集合可以按照前文的介绍,以嵌套方式设置,或者也可以不按照嵌套方式设置,而是按照其他的方式设置。且,网络设备在指示终端设备进行配置参数集合的切换时,也不需要使得切换后的配置参数集合对应的候选PDCCH的资源是切换前的配置参数集合对应的候选PDCCH的资源的子集,也就是,无需限制切换后的配置参数集合,切换后的配置参数集合对应的候选PDCCH的资源可以是切换前的配置参数集合对应的候选PDCCH的资源的子集,或者切换后的配置参数集合对应的候选PDCCH的资源也可以不是切换前的配置参数集合对应的候选PDCCH的资源的子集。
例如,协议或者网络设备可以预配置至少一个MAC CE,至少一个MAC CE的数量可以等于N个配置参数集合包括的配置参数集合的数量,也就是,MAC CE与N个配置参数集合包括的配置参数集合一一对应,一个MAC CE表示一种配置参数集合。那么,网络设备发送哪个MAC CE,就表示指示终端设备将配置参数集合切换到哪个配置参数集合,也就是,网络设备所发送的MAC CE指示的是切换后的配置参数集合。或者,网络设备也可以通过1个MAC CE来指示终端设备切换配置参数集合,这1个MAC CE指示的可以是切换后的配置参数集合的信息,那么网络设备发送MAC CE后,终端设备可以切换到默认设置的配置参数集合,该默认设置的配置参数集合例如是网络设备或协议预先设置的。或者,网络设备也可以通过1个MAC CE以及MAC CE的载荷来指示终端设备切换配置参数集合,例如网络设备可以通过1个MAC CE指示终端设备切换配置参数集合,以及在该MAC CE的载荷中可以承载切换后的配置参数集合的信息,从而终端设备接收MAC CE后,根据MAC CE确定切换配置参数集合,以及根据该MAC CE的载荷可以确定需要切换到哪个配置参数集合。
S25、终端设备从第二配置参数集合切换到第一配置参数集合。
以通知信息是指示终端设备第二配置参数集合的信息、且第一配置参数集合与第二配置参数集合不同为例,则终端设备从第二配置参数集合切换到第一配置参数集合,如果第一配置参数集合与第二配置参数集合相同,则终端设备继续维持当前的配置参数集合,“维持”的操作,可以理解为终端设备也执行了S25,或者,因为第一配置参数集合和第二配置参数集合相同,或者也可以理解为终端设备不执行S25。
当然,执行S25,是建立在终端设备接收到了通知信息的情况,如果终端设备未接收 到通知信息,那么终端设备不会执行S25,也就不会切换配置参数集合,例如终端设备维持第二配置参数集合。此时,如果通知信息通过MAC CE承载,则终端设备不会向网络设备回复应答信息,网络设备未收到终端设备发送的应答信息,也就可以不调整配置参数集合,维持与终端设备相同的配置参数集合。而如果通知信息为第一下行控制信息或第二下行控制信息,则网络设备会切换配置参数集合,例如从第二配置参数集合切换为第一配置参数集合,而按照前文的介绍,第一配置参数集合对应的候选PDCCH的资源是第二配置参数集合对应的候选PDCCH的资源的子集,因此,虽然终端设备继续按照第二配置参数集合盲检测候选PDCCH,终端设备也依然能够检测到网络设备按照第一配置参数集合所发送的PDCCH,减小了终端设备漏检PDCCH的可能性。
当然,如果终端设备要进行配置参数集合的切换,则很难保证终端设备和网络设备始终对于配置参数集合保持相同的认知,也就是很难保证终端设备和网络设备始终维持在相同的配置参数集合。例如,在一个DRX周期包括的检测候选PDCCH的状态结束时,终端设备可能维持在配置参数集合1,而网络设备可能理解终端设备维持在配置参数集合2,从而在下一个DRX周期包括的检测候选PDCCH的状态开始时,网络设备会按照配置参数集合2来发送PDCCH,而终端设备又会按照配置参数集合1来检测候选PDCCH,导致网络设备的发送行为和终端设备的检测行为不一致。特别是,如果按照本申请实施例提供的一种技术方案,终端设备在进行状态切换时,可能切换后的配置参数集合对应的候选PDCCH的资源是切换前的配置参数集合对应的候选PDCCH的资源的子集,如果终端设备实际上已经切换到了配置参数集合2,而网络设备认为终端设备还停留在配置参数集合1,配置参数集合1对应的候选PDCCH的资源是配置参数集合2对应的候选PDCCH的资源的子集,则网络设备在配置参数集合1对应的候选PDCCH的资源上发送PDCCH,而终端设备在配置参数集合2对应的候选PDCCH的资源上盲检测候选PDCCH,就会导致终端设备漏检PDCCH。
鉴于此,为了让网络设备和终端设备能在发生认知错误后自动的修复,本申请实施例还提出,终端设备在从不检测候选PDCCH的状态改变为检测候选PDCCH的状态时,或者说,终端设备在由不检测候选PDCCH的时隙进入检测候选PDCCH的时隙时,或者说,在第a个DRX周期中终端设备开始检测候选PDCCH的一个或多个时隙,自动进入第三配置参数集合,或者理解为,终端设备在上一个DRX周期结束后进入下一个DRX周期内的检测候选PDCCH的状态时,自动进入第三配置参数集合。同理,网络设备在终端设备由不检测候选PDCCH的时隙进入检测候选PDCCH的时隙时,时,或者说,在终端设备的第a个DRX周期中该终端设备开始检测候选PDCCH的一个或多个时隙,也在第三配置参数集合对应的候选PDCCH的资源上发送PDCCH。也就是,无论终端设备在上一个DRX周期内是否接收了要求切换到第三配置参数集合的指示,在进入下一个DRX周期内的检测候选PDCCH的状态时,终端设备都自动进入第三配置参数集合,而网络设备也同样,在确定终端设备由不检测候选PDCCH的时隙进入检测候选PDCCH的时隙时,或者说确定在终端设备的第a个DRX周期中该终端设备开始检测候选PDCCH的一个或多个时隙,网络设备也在第三配置参数集合对应的候选PDCCH的资源上发送PDCCH,这样,在每个DRX周期起始,网络设备和终端设备的配置参数集合始终是保持一致的。
其中,第三配置参数集合可以是N个配置参数集合中的特定的配置参数集合,例如第三配置参数集合可以是通过至少一个第二消息配置的配置参数集合,也就是现有技术中网 络设备会为终端设备配置的配置参数集合,因为现有技术中网络设备为终端设备配置的配置参数集合,所对应的终端设备的检测候选PDCCH的能耗一般都比较高,终端设备在每个DRX周期起始,进入这样的配置参数集合,有助于全力检测候选PDCCH,而且如果终端设备在进行状态切换时要按照本申请实施例提出的方案,只从高检测候选PDCCH的能耗的状态切换为低检测候选PDCCH的能耗的状态,则终端设备在每个DRX周期起始进入较高检测候选PDCCH的能耗的配置参数集合,也有助于后续的配置参数集合的切换。或者,第三配置参数集合也可以是通过至少一个第一消息配置的N个配置参数集合或N-1个配置参数集合中的一个。
如果第三配置参数集合是通过至少一个第一消息配置的N个配置参数集合或N-1个配置参数集合中的一个那么,至少一个第一消息除了用于配置N个配置参数集合或N-1个配置参数集合之外,还可以用于指示特定的配置参数集合,也就是第三配置参数集合,或者,第三配置参数集合也可以不通过至少一个第一消息指示,而是通过协议或其他方式预定义,或由网络设备预先配置,或者第三配置参数集合也可以是N个配置参数集合或N-1个配置参数集合中默认的配置参数集合等。例如,默认的配置参数集合为N个配置参数集合中通过至少一个第一消息配置的一个配置参数集合;或者,默认的配置参数集合为N个配置参数集合中通过至少一个第二消息配置的配置参数集合。
其中,配置第三配置参数集合,可以通过配置第三配置参数集合的索引来实现。例如,可以为N个配置参数集合统一设置索引,那么第三配置参数集合的索引就是根据统一设置的索引确定的;或者,N个配置参数集合包括通过至少一个第一消息配置的N-1个配置参数集合和通过至少一个第二消息配置的一个配置参数集合,那么可以为这N-1个配置参数集合统一设置索引,以及为通过至少一个第二消息配置的一个配置参数集合单独设置索引,那么第三配置参数集合的索引就是根据为N-1个配置参数集合统一设置的索引确定的,或是根据为一个配置参数集合单独设置的索引确定的。
作为一种示例,第三配置参数集合可以是N个配置参数集合中所对应的终端设备的检测候选PDCCH的能耗最高的配置参数集合。
其中,终端设备在从不检测候选PDCCH的状态进入检测候选PDCCH的状态时,或者说,终端设备在由不检测候选PDCCH的时隙进入检测候选PDCCH的时隙时,或者说,在第a个非连续接收状态周期中终端设备开始检测候选下行控制信道的一个或多个时隙,自动进入第三配置参数集合,该技术方案可以独立应用,也就是不与前文所述的将N个配置参数集合嵌套设置的方案、以及通过下行控制信息或MAC CE指示终端设备进行配置参数集合的切换等方案结合应用;或者,终端设备在从不检测候选PDCCH的状态进入检测候选PDCCH的状态时,或者说,终端设备在由不检测候选PDCCH的时隙进入检测候选PDCCH的时隙时,或者说,在第a个非连续接收状态周期中终端设备开始检测候选下行控制信道的一个或多个时隙,自动进入第三配置参数集合,该技术方案也可以与前文所述的技术方案结合应用,例如可以与将N个配置参数集合嵌套设置的方案结合应用,或者可以与通过MAC CE指示终端设备进行配置参数集合切换的方案结合应用,或者可以与将N个配置参数集合嵌套设置的方案、以及通过下行控制信息指示终端设备进行配置参数集合切换的方案结合应用等,具体的不做限制。
以在第a个非连续接收状态周期中终端设备开始检测候选下行控制信道的一个或多个时隙,自动进入第三配置参数集合,该技术方案与N个配置参数集合嵌套设置的方案、以 及通过下行控制信息指示终端设备进行配置参数集合切换的方案结合应用为例,可参考图4。图4中的一个方框表示一个配置参数集合,方框的高度不同,代表配置参数集合所对应的终端设备的检测候选PDCCH的能耗不同,方框的高度越高表明终端设备的检测候选PDCCH的能耗越高。可以看到,在检测候选PDCCH的状态中,网络设备是指示终端设备从高检测候选PDCCH的能耗状态切换到低检测候选PDCCH的能耗状态,图4中竖直的虚线表示两个DRX周期的分界线,在下一个DRX周期中终端设备开始检测候选下行控制信道的一个或多个时隙,根据弧线的虚线指示可知,终端设备自动切换到高检测候选PDCCH的能耗的状态,也就是自动切换了配置参数集合,例如切换到了第三配置参数集合。当然,图4只是示例,本申请实施例对于终端设备的具体切换方式,以及各个配置参数集合对应的终端设备的检测候选PDCCH的能耗之间的关系等不做限制。
