本申请要求在2020年04月10日提交中国专利局、申请号为202010281678.7、申请名称为“一种检测方法及装置”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。
本申请涉及通信技术领域,尤其涉及一种检测方法及装置。
第三代合作伙伴计划(3rd generation partnership project,3GPP)标准组织目前正在制定的新空口(new radio,NR)***,与LTE***相比,具有支持更大的传输带宽,更高的传输速率以及更低的时延等优点。NR***的上述特性虽然为NR***提供了更多的适用范围,但却极大的增加了终端侧设备的功耗负担。
为了降低终端侧设备的功率消耗,3GPP在Rel-16版本的NR***中引入了非连续接收(discontinuous reception,DRX)机制。当终端侧设备被配置了DRX时,终端侧设备的状态可以分为DRX激活(Active)态和DRX非激活(non-active)态。终端侧设备每隔一定的周期,在DRX持续时间(ON Duration)处于DRX Active态,终端侧设备处于DRX Active态的持续时间也称为激活时间(Active Time)。当终端侧设备处于Active Time,会持续检测物理下行控制信道(physical downlink control channel,PDCCH)。如果终端侧设备进入睡眠状态(DRX non-active),则不去检测PDCCH。
为了进一步降低终端侧设备的功率消耗,在DRX ON Duration之前,还可以通过发送唤醒信号(wake up signal,WUS)指示信息用于指示终端侧设备在接下来的一个或多个DRX周期内是否去检测PDCCH。
进一步的,在很多情况下,网络侧设备并不是一直向终端侧设备调度数据,但是终端侧设备仍需要周期性检测PDCCH才能确定是否有调度,如果网络侧设备和终端侧设备之间没有业务传输,没有调度数据,那么造成终端侧设备的PDCCH空检(PDCCH-only),带来功耗浪费。因此,为了进一步降低终端侧设备的功率消耗,在DRX ON Duration之前,网络侧设备还可以通过下行控制信息(downlink control information,DCI)发送休眠指示(dormancy indication)信息,休眠指示信息用于指示终端侧设备进行BWP切换。终端侧设备接收到休眠指示信息,可以执行BWP切换,例如切换到休眠BWP上,从而不用检测PDCCH。BWP切换需要一定的时间,在BWP切换期间,终端侧设备不能接收或发送数据。
目前,唤醒信号指示信息是一定会发送的,但是休眠指示信息是可选的。如果同时通过DCI发送唤醒信号指示信息和休眠指示信息的情况下,如何确定BWP切换的起始时间,避免终端侧设备和网络侧设备对BWP切换的起始时间的定义不一致,导致终端侧设备无法接收到数据,是一个亟待解决的问题。
发明内容

通过这种方法,终端侧设备可以明确在第一时间段进行BWP切换,避免终端侧设备在任意的时间段进行BWP切换时,导致在进行BWP切换时,发生数据丢失的问题。

如上介绍了本申请实施例涉及的一些概念,下面介绍本申请实施例涉及的技术特征。
一、非连续接收(discontinuous reception,DRX)机制。
在LTE***中,3GPP设计了DRX机制(或称为DRX模式,或DRX状态等)以降低连接态的终端侧设备的功耗。配置了DRX的终端侧设备,在无线资源控制(Radio Resource Control,RRC)连接态会不连续接收,此时终端侧设备的状态也可以称为连接DRX(Connected-DRX,C-DRX)态。
DRX机制可以让终端侧设备周期性地在某些时候(可定义为非激活时间(inactive time))进入睡眠状态(sleep mode),不去检测指定的小区无线网络临时标识(cell radio network temporary identity,C-RNTI)加掩的PDCCH,而在需要检测的时候(可定义为激活时间(active time)),则从睡眠状态中唤醒(wake up)并检测这些PDCCH,这样就可以降低终端侧设备功耗。
DRX机制下的基本时间单位为DRX周期,或称为DRX循环(cycle)。举例来说,如图2所示。在图2中,一个DRX循环包括DRX持续时间(ON duration)和DRX机会(opportunity for DRX)。其中,DRX持续时间也可以简称为持续时间,本申请实施例中统称为DRX持续时间。
在本申请实施例中,终端侧设备在DRX持续时间的状态可以称为DRX active态,也可以称为唤醒(wake up)状态,还可以称为DRX_ON。在DRX持续时间内,终端侧设备将被唤醒,并检测和接收PDCCH,本申请实施例中将唤醒状态也称为激活态。终端侧设备处于DRX active态的时间也称为激活时间(active time)。
本申请实施例中,终端侧设备在DRX机会内的状态可以称为DRX非激活(non-active)态,或者也可以称为睡眠状态(sleep mode),或者也可以称为DRX_OFF。终端侧设备处于DRX非激活态的时间也称为非激活时间(non-active time)。
处于DRX非激活态的终端侧设备可以关闭射频收发器(或接收机)和基带处理器等通信器件以降低功耗,或者虽然打开了射频器件,但是只做一些功耗较低的检测过程,例如检测一些终端侧设备必须检测的消息,如寻呼消息、广播消息、或***消息等。需要说明的是,处于非激活时间的终端侧设备,只是不接收PDCCH中的一类DCI。例如,对于NR***来说,终端侧设备在非激活时间内不需要检测指定的PDCCH,其中指定的PDCCH是指该PDCCH的循环冗余校验(cyclic redundancy check,CRC)采用以下任一方式加扰:
采用小区无线网络临时标识(cell RNTI,C-RNTI)、配置调度无线网络临时标识 (configured scheduling RNTI,CS-RNTI)、中断RNTI(interruption RNTI,INT-RNTI)、时隙格式指示RNTI(slot format indicator-RNTI,SFI-RNTI)、半持续信道状态指示RNTI(semi-persistent channel state information RNTI,SP-CSI-RNTI)、发射功率控制物理上行控制信道(physical uplink control channel,PUCCH)-RNTI(transmit power control PUCCH RNTI,TPC-PUCCH-RNTI)、发射功率控制物理上行共享信道(physical uplink shared channel,PUSCH)RNTI(transmit power control PUSCH RNTI,TPC-PUSCH-RNTI)或发射功率控制探测参考信号(sounding reference signal,SRS)RNTI(transmit power control RNTI,TPC-SRS-RNTI)。
终端侧设备在激活时间则需要检测这些RNTI加扰的PDCCH。
处于非激活时间的终端侧设备,可以接收PDCCH中的其他不受终端侧设备是否处于激活时间影响的DCI,以及可以接收来自其他物理信道的数据,例如物理下行共享信道(physical downlink shared channel,PDSCH)、确认应答(acknowledgment,ACK)、否定应答(negative-acknowledgment,NACK)等。
二、唤醒信号(wakeup signalling,WUS)指示信息。
为了进一步降低终端侧设备的功耗,引入了唤醒信号指示信息,该唤醒信号指示信息通过DCI发送,该DCI的DCI格式可以为DCI格式2_6(DCI format 2_6),该DCI的CRC由省功耗RNTI(power saving RNTI,PS-RNTI)加扰。具体的,位于DRX On duration之前,可以通过唤醒信号指示信息指示终端侧设备在接下来的一个或多个DRX cycle是否唤醒去检测PDCCH。
举例来说,如图3所示,如果终端侧设备检测到包括唤醒信号指示信息的DCI,则开启定时器(标准中称为drx-ondurationTimer),并在DRX持续时间内检测PDCCH;如果终端侧设备未检测到包括唤醒信号指示信息的DCI,则不开启drx-ondurationTimer,即终端侧设备不在该DRX cycle唤醒,而进入睡眠状态节省功耗。
需要说明的是,由于终端侧设备检测唤醒信号指示信息的功耗和复杂度远小于在DRX持续时间内检测PDCCH的功耗和复杂度,因此通过唤醒信号指示信息可以极大地节省终端侧设备的功耗。
具体的,结合前面的图3。网络侧设备可以配置省功耗偏移(PS_offset),图3中记为PS_OF。PS_offset可以用于确定终端侧设备检测唤醒信号指示信息的起始时间。终端侧设备可以在DRX持续时间的起始时间之前,且与DRX持续时间的起始时间间隔所述省功耗偏移的时间开始检测唤醒信号指示信息,在图3中以时间1表示终端侧设备开始检测唤醒信号指示信息的时间。
进一步的,终端侧设备并不是在DRX持续时间之前一直检测唤醒信号指示信息。以图3为例,终端侧设备可以在DRX持续时间之前的时间2停止检测唤醒信号指示信息。时间2与DRX持续时间的起始时间之间的时长为第一偏移,也可以称为最小偏移(minimum offset),图3中记为M_OF,第一偏移可以是终端侧设备上报给网络的所述终端侧设备从休眠态转换为唤醒态所需的时间。所述终端侧设备在所述第一偏移内不要求检测特定DCI format的DCI,即终端侧设备在所述第一偏移内不检测特定DCI format的DCI。
其中,第一偏移也可以称为最小间隔(minimum gap)等名称,本申请实施例不对其名称进行限定。
三、休眠指示(dormancy indication)信息。
在载波聚合技术中,3GPP已经定义了辅载波(secondary cell,SCell)的休眠机制。当SCell被指示为dormancy状态时,那么在该SCell上,终端侧设备将从当前下行激活的带宽部分(bandwidth part,BWP)切换到休眠BWP,休眠BWP可以是指没有配置PDCCH搜索空间的BWP,或者不需要进行PDCCH monitoring的BWP。由于在休眠BWP上终端侧设备可以不进行PDCCH检测,从而节省功耗。网络侧设备可以通过休眠指示信息指示终端侧设备进行BWP切换。需要说明的是,网络侧设备可以通过休眠指示信息指示终端侧设备从非休眠(non dormancy)BWP切换到休眠BWP上,也可以从休眠BWP切换到特定非休眠BWP上。
举例来说,网络侧设备配置了4个SCell,其中,4个SCell分为两组,SCell group 1和SCell group 2。休眠指示信息有2比特,分别对应一组SCell group,网络侧设备向终端侧设备发送包括休眠指示信息的DCI,其中休眠指示信息对应的2比特取值为“10”,那么SCell group 1的SCell为non dormancy状态,终端侧设备将在SCell group 1的SCell监听PDCCH和数据传输,SCell group 2的SCell为dormancy状态,终端侧设备将工作在休眠BWP上,不监听PDCCH。
终端侧设备进行BWP切换所需的时间,可以称为BWP切换时延(BWP switching delay)。BWP切换时延包括:PDCCH解调与DCI译码时间、基带处理时间(比如参数计算等)、射频转换时间(RF transition time)等。BWP切换时延是终端侧设备根据自身的能力,上报给网络侧设备的。
目前,当网络侧设备通过一个DCI同时发送唤醒信号指示信息和休眠指示信息时,如何约定BWP切换时延的开始时间,还没有明确的解决方案。本申请实施例提供一种方法,可以使得终端侧设备与网络侧设备确定相同的BWP切换时延的开始时间,避免终端侧设备在BWP切换期间,网络侧设备向终端侧设备发送数据,导致终端侧设备丢失数据。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案,并不构成对于本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
需要说明的是,在实施本申请实施例提供的方法之前,终端侧设备与网络侧设备之间可以执行以下步骤:
步骤一:终端侧设备通过信令上报终端侧设备的能力信息,所述能力信息包括但不限于:第一偏移和BWP切换时延。
其中,第一偏移可以用于确定在DRX持续时间的起始时间之前,终端侧设备停止检测特定DCI format的DCI的最晚时间。所述特定DCI format的DCI中携带唤醒信号指示信息,还可以携带休眠指示信息。具体的,终端侧设备停止检测所述特定DCI format的DCI的时间位于DRX持续时间的起始时间之前,且与DRX持续时间的起始时间之间至少间隔所述第一偏移。
不失一般性,所述特定DCI format为网络配置或者预设。
作为一个例子,所述特定DCI format为NR***中DCI format 2_6。
BWP切换时延,指示出终端侧设备在不同子载波的BWP中,执行BWP切换所需的时长。举例来说,终端侧设备上报的BWP切换时延与子载波间隔的对应关系可以如表1 所示。
表1
子载波间隔 | BWP切换时延(时隙) |
15KHz | 1 |
30KHz | 2 |
60KHz | 3 |
120KHz | 6 |
需要说明的是,表1只是示例,BWP切换时延与子载波间隔的对应关系还可存在其他形式,在此不再逐一举例说明。
终端侧上报的能力信息,还可以包括其它信息,在此不再追一举例说明。
所述第一最小间隔和BWP switching delay可以在相同的信令或者不同的信令中上报。
步骤二:网络侧设备向终端侧设备发送配置信息。
所述配置信息中包含所述特定DCI format的DCI的配置信息,包括但不限于:所述特定DCI format的DCI关联的搜索空间集合(Search space set)的配置,以及省功耗偏移(PS_offset)、加扰该DCI的PS-RNTI等信息。
其中,所述特定DCI format的DCI关联的搜索空间集合的配置,可以用于指示该DCI对应的监测时机(monitoring occasion)的位置,终端侧设备可以在每个监测时机中检测所述特定DCI format的DCI。省功耗偏移可以用于确定检测所述特定DCI format的DCI的起始时间,具体的,终端侧设备检测所述特定DCI format的DCI的起始时间在DRX持续时间的起始时间之前,且与DRX持续时间的起始时间之间的时长为所述省功耗偏移。终端侧设备可以根据特定RNTI确定检测到的DCI是否为所述特定DCI format的DCI。
作为一个例子,所述特定RNTI为PS-RNTI,特定DCI format为NR***中DCI format 2_6。
网络侧设备发送的配置信息还可以包括其它信息,在此不再追一举例说明。
终端侧设备可以根据上述配置信息,在DRX持续时间之前,检测所述特定DCI format的DCI,下面将分别进行描述。
实施例一:
在实施例一中,主要描述如何确定BWP切换时延的开始时间,具体的,如图4所示,为本申请实施例提供的一种检测方法流程示意图。该方法包括:
步骤401:网络侧设备在DRX持续时间的起始时间之前的监测时机中发送第一指示信息。
其中,所示第一指示信息可以是指前面描述的休眠指示信息,所述第一指示信息用于指示终端侧设备进行BWP切换。
需要说明的是,关于第一指示信息等技术特征,将在后面详细描述。
步骤402:网络侧设备根据所述DRX持续时间的起始时间之前的多个监测时机中的第N个监测时机确定第一时间段。
所述第一时间段为所述终端侧设备被允许进行BWP切换的时间段。
其中,所述多个监测时机位于第一时间至第二时间内,关于第一时间和第二时间的具体内容,将在后面进行描述。
本申请实施例中,N为大于0的整数。第N个监测时机可以为所述多个监测时机中的 第1个监测时机,也可以为所述多个监测时机中的最后1个监测时机,本申请实施例并不限定。
作为一个例子,本申请实施例中一个设计为根据多个监测时机中的最后一个监测时机,确定第一时间段。
步骤403:终端侧设备在DRX持续时间的起始时间之前的多个监测时机进行检测。
所述检测是指终端侧设备根据特定DCI format对备选PDCCH进行监测。备选PDCCH中可能存在所述特定DCI format,终端侧设备需要通过检测来确定备选PDCCH中是否存在所述特定DCI format。
需要说明的是,终端侧设备是在多个监测时机中监测所述特定DCI format,本申请实施例中特定DCI format可以是指DCI format 2_6的DCI。
步骤404:若终端侧设备检测到来自网络侧设备的第一指示信息,则根据所述DRX持续时间的起始时间之前的所述多个监测时机中的第N个监测时机确定第一时间段,并在第一时间段内进行BWP切换。
需要说明的是,步骤401和步骤404中,第一指示信息可以指示终端侧设备从未休眠BWP切换到休眠BWP,也可以指示终端侧设备从休眠BWP切换到特定未休眠BWP,具体根据实际情况确定。休眠BWP可以是指没有配置PDCCH搜索空间的BWP或者被配置为不接收或者监测PDCCH的BWP,未休眠BWP可以是指除休眠BWP之外配置的其他BWP,例如配置PDCCH搜索空间的BWP,或者被配置监测PDCCH的BWP。终端侧设备在休眠BWP中可以不再监测PDCCH,从而节省功耗。
需要说明的是,所述第一指示信息是通过特定DCI format,例如DCI format 2_6的DCI发送的,该DCI中还可以携带第二指示信息,第二指示信息可以是指前面描述的唤醒指示信息。第二指示信息用于指示所述终端侧设备是否在所述DRX持续时间的起始时间唤醒。所述唤醒是指在DRX持续时间的起始时间启动持续时间定时器。
示例性的,监测时机,是终端侧设备根据特定DCI format监测备选PDCCH的时间单元,网络侧设备可以将监测特定DCI format的搜索空间集合(Search Space Set)对应的监测时机通过配置信息指示给终端侧设备。为了使得终端侧设备检测到所述特定DCI format的DCI,网络侧设备在发送所述特定DCI format的DCI时,也会在对应的监测时机发送该DCI。
步骤402和步骤403中,第一时间段的时长可以等于终端侧设备确定的BWP切换时延。进一步的,所述第一指示信息用于指示终端侧设备进行BWP切换时,可以指示终端侧设备在至少一个小区中进行BWP切换,所述至少一个小区可以属于一个辅小区组(SCell group),此时第一时间段的时长可以等于所述第一指示信息指示的至少一个小区对应的BWP切换时延。
其中,至少一个小区对应的BWP切换时延可以是根据至少一个小区所包括的下行子载波的子载波间隔确定的。例如,结合表1,当至少一个小区所包括的下行载波的子载波间隔为30KHz时,至少一个小区对应的BWP切换时延可以为2个时隙,相应的,第一时间段的时长等于2个时隙。
本申请实施例中,第一时间段的起始时间可以为所述多个监测时机中的第N个监测时机所包括的最后一个时间单元的结束时间。其中所述时间单元可以是指NR***中的时隙 (slot),也可以是指LTE***中的子帧等,本申请实施例并不限定。
进一步的,结合前面的描述,第一时间段的时长等于终端侧设备确定的BWP切换时延,所述多个监测时机中的第N个监测时机所包括的最后一个时间单元的结束时间则可以表示BWP切换时延的起始时间。
不失一般性,本申请实施例中用DCI format 2_6作为特定DCI format的一个例子进行描述,本申请实施例不限定所述特定DCI format的具体格式。
本申请实施例中,所述第一时间与所述第二时间均位于所述DRX持续时间的起始时间之前,所述第二时间位于所述第一时间与所述DRX持续时间的起始时间之间。所述第一时间为在所述DRX持续时间的起始时间之前,终端侧设备开始检测DCI format 2_6的DCI的时间;相应的,在第二时间之后,终端不要求监测对应于DCI format 2_6的PDCCH candidate,即可以理解为在第二时间至所述DRX持续时间的起始时间之间,所述终端侧设备不检测DCI format 2_6的DCI。
在本申请实施例中,检测DCI format 2_6的DCI,可以是指监测DCI format 2_6的DCI对应的备选PDCCH。
进一步的,所述第一时间与所述DRX持续时间的起始时间之间的时长为网络侧设备配置的。举例来说,第一时间与所述DRX持续时间的起始时间之间的时长为前面描述的省功耗偏移(PS_offset)参数进行配置。
省功耗偏移可以用于确定检测DCI format 2_6的DCI的起始时间,具体的,终端侧设备检测DCI format 2_6的DCI的起始时间在DRX持续时间的起始时间之前,且与DRX持续时间的起始时间之间的时长为所述省功耗偏移。
进一步的,一种可能的实现方式中,所述第二时间可以按照现有技术方式的方法确定,即第二时间与DRX持续时间的起始时间之间的时长可以等于终端侧设备确定并上报的第一偏移。
另一种可能的实现方式中,还可以按照实施例二中的方式确定第二时间,具体可以参考后面的实施例二中的描述。
进一步的,如果终端侧设备在DRX持续时间的起始时间唤醒,则最好在DRX持续时间的起始时间之前完成BWP切换。基于此,本申请实施例中,如果所述DRX持续时间的起始时间位于所述第一时间段内,一种可能的实现方式中,可以将所述DRX持续时间的起始时间推迟到所述第一时间段的结束时间。另一种可能的实现方式中,可以保持DRX持续时间的起始时间不变,此时第一时间段将与DRX持续时间重叠。具体采用哪种方式,可以根据实际情况确定。
结合图4,如图5所示,为本申请实施例提供的一种时序示意图。图5中,以时间单元为NR***中的时隙为例进行描述。网络侧设备配置的省功耗偏移包括4个时隙(slot),终端侧设备可以从位于DRX持续时间的起始时间之前4个时隙的第一时间开始检测所述特定DCI format。终端侧设备确定的第一偏移包括1个时隙,终端侧设备最晚在DRX持续时间的起始时间之前的1个时隙的第二时间停止检测,终端侧设备在位于DRX持续时间的起始时间之前1个时隙的第二时间之后可以停止检测所述特定DCI format。
结合前面的描述可知,第一时间至第二时间之间包括3个时隙,第二时间至DRX持续时间的起始时间(第三时间)之间包括1个时隙。假设第一时间至第二时间之间包括2 个监测时机,分别位于时隙2和时隙3中。第一偏移中也包括1个监测时机,位于时隙4中。图5中以每个监测时机中存在网络侧设备发送的DCI format 2_6的DCI为例进行说明,该DCI中包括第一指示信息和第二指示信息。
图5中,终端侧设备在第一时间至第二时间内监测DCI format 2_6的DCI,终端侧设备在第二时间与第三时间之间不监测该DCI。
终端侧设备在第一时间至第二时间内检测DCI format 2_6,是指在第一时间至第二时间内,在多个监测时机上根据DCI format 2_6,监听备选PDCCH。
假设第N个监测时机为第一时间至第二时间之间的最后一个监测时机。如果终端侧设备在第一时间至第二时间内的第1个监测时机检测到DCI format 2_6的DCI,则可以将所述第一时间至所述第二时间内的最后一个监测时机所包括的最后一个时隙的结束时间,作为第一时间段的起始时间。从图5中看,终端侧设备在时隙2检测到DCI,第一时间段的起始时间为时隙3(最后一个检测时机所包括的时隙)的结束时间。终端侧设备在第一时间段内进行BWP切换。
需要说明的是,终端侧设备无论在哪个监测时机检测到第一指示信息,均在第一时间段内,根据第一指示信息的指示进行BWP切换。
进一步的,终端侧设备如果确定检测到DCI format 2_6的DCI,且所述DCI包含所述终端侧设备的第二指示信息,且第二指示信息指示所述终端侧设备在所述DRX持续时间的起始时间唤醒,则终端侧设备可以开启定时器drx-onDurationTimer。所述‘唤醒’即指终端侧设备在预设或者预配置位置开启定时器drx-onDurationTimer。所述预设或预配置位置可以根据网络的配置参数确定。如果在DRX持续时间内,终端侧设备收到PDCCH指示下行或上行新的数据传输,则会开启(或重启)定时器drx-InactivityTimer。终端侧设备将一直处于DRX Active态直到定时器drx-InactivityTimer定时器超时,或者终端侧设备收到指示该定时器drx-InactivityTimer提前停止的指令。
前面的实施例一描述如何确定终端侧设备被允许进行BWP切换的时间段的起始时间,下面将描述如何确定终端侧设备停止检测DCI的时间,即如何确定第二时间。需要说明的是,实施例二也可以应用于实施例一中,即实施例二和实施例一可以结合起来实施,也可以分别独立实施。
实施例二:
实施例二具体包括以下流程:
步骤一:终端侧设备在DRX持续时间的起始时间之前的第一时间开始进行检测DCI。
其中,所述第一时间与所述DRX持续时间的起始时间之间的时长为网络侧设备配置的,具体可以参考前面的描述。所述DCI包括第一指示信息以及第二指示信息,所述DCI的格式可以为DCI format 2_6。所述第一指示信息用于指示所述终端侧设备进行BWP切换;所述第二指示信息用于指示所述终端侧设备是否在所述DRX持续时间的起始时间唤醒;所述‘唤醒’即指终端侧设备在预设位置开启定时器drx-onDurationTimer。第一指示信息以及第二指示信息的具体内容可以参考前面的描述,在此不再赘述。
步骤二:终端侧设备在第二时间之前停止检测所述DCI,第二时间位于所述DRX持续时间的起始时间之前。
其中,终端侧设备最晚在DRX持续时间的起始时间之前的第二时间停止检测。所述 第二时间是根据第二时间段和第一时间段确定的,所述第一时间段为所述终端侧设备被允许进行BWP切换的时间段,第一时间段的具体内容可以参考前面的描述,在此不再赘述。
本申请实施例中,所述第二时间段为终端侧设备上报的第一偏移,所述终端侧设备在所述第二时间段内不要求检测所述DCI。
在本申请实施例中,所述终端侧设备在所述第二时间段内不要求检测所述DCI,是指网络侧设备认为终端侧设备不会在所述第二时间段内监测所述DCI。
进一步的,本申请实施例中,所述第二时间与所述DRX持续时间的起始时间之间的时长可以为所述第二时间段的时长和所述第一时间段的时长中的最大值。
举例来说,结合图6,为本申请实施例提供的一种时序示意图。图6中,以时间单元为NR***中的时隙为例进行描述。网络侧设备配置的省功耗偏移包括4个时隙(slot),终端侧设备可以从位于DRX持续时间的起始时间之前4个时隙的第一时间开始检测。终端侧设备确定的第一偏移包括1个时隙,第二时间段可以包括1个时隙。假设第一时间段包括2个时隙,那么第二时间与所述DRX持续时间的起始时间之间的时长可以为2个时隙,即终端侧设备最晚可以在位于DRX持续时间的起始时间之前2个时隙的第二时间停止检测。
结合前面的描述可知,图6中,终端侧设备在第一时间至第二时间内包括的3个时隙检测DCI,终端侧设备在第二时间与第三时间之间包括的2个时隙不检测DCI。
进一步的,第一时间段的时长为终端侧设备确定的BWP切换时延。如果所述第一指示信息用于指示终端侧设备在至少一个小区中进行BWP切换,所述至少一个小区可以属于一个辅小区组(Scell group),此时第一时间段的时长可以根据所述至少一个小区包括的所有下行载波中,最小子载波间隔对应的BWP切换延时确定。例如第一时间段的时长可以等于所述至少一个小区包括的所有下行载波中,最小子载波间隔对应的BWP切换时延。
举例来说,结合表1,当至少一个小区包括小区1和小区2时,小区1所包括的下行载波的子载波间隔为30KHz时,小区2所包括的下行载波的子载波间隔为60KHz时,第一时间段的时长可以等于30KHz的子载波间隔对应的BWP切换时延,即包括2个时隙。
进一步的,第二时间段的时长也可以根据所述至少一个小区包括的所有下行载波中,所有下行载波对应的第一偏移的绝对时间的最大值确定。
进一步的,第二时间段的时长也可以根据所述至少一个小区包括的所有下行载波中,所有下行载波对应的最小子载波间隔对应的第一偏移。
进一步的,第二时间段的时长也可以根据所述至少一个小区包括的所有下行载波中,所有下行载波对应的最大子载波间隔对应的第一偏移。
举例来说,终端侧设备确定的第一偏移和子载波间隔的对应关系可以如表2所示。
表2
子载波间隔 | 第一偏移(时隙) |
15KHz | 1 |
30KHz | 1 |
60KHz | 2 |
120KHz | 3 |
需要说明的是,表2只是示例,第一偏移与子载波间隔的对应关系还可存在其他形式,在此不再逐一举例说明。
结合表2,当至少一个小区包括小区1和小区2时,小区1所包括的下行载波的子载波间隔为30KHz时,小区2所包括的下行载波的子载波间隔为60KHz时,第二时间段的时长可以等于30KHz的子载波间隔对应的BWP切换时延,即包括1个时隙。
进一步的,本申请实施例中,第一时间至第二时间内可以包括至少一个监测时机。
进一步的,当终端侧设备被网络设备配置为在所检测到的特定DCI format中仅包含所述终端侧设备的第二指示信息而不包含所述终端侧设备的第一指示信息时,所述终端侧设备根据第一时间段确定第二时间;当终端侧设备被网络设备配置为在所检测到的特定DCI format中包含所述终端侧设备的第一指示信息和二指示信息时,所述终端侧设备根据第一时间段和第二时间段的确定第二时间,典型地,根据第一时间段和第二时间段的最大值确定第二时间。网络设备确定第二时间的方式和终端侧设备确定第二时间的方式对应,不再赘述。
进一步的,如果所述第一时间至所述第二时间内不包括监测时机或者不包括有效的监测时机,则所述终端侧设备在所述DRX持续时间内,使用配置了PDCCH搜索空间的BWP进行通信。
具体的,如果在所述DRX持续时间的起始时间之前,终端侧设备工作在休眠BWP中,即终端侧设备使用没有配置PDCCH搜索空间的BWP进行通信,那么终端侧设备在所述DRX持续时间的起始时间之前,切换到非休眠BWP中,即切换到配置了PDCCH搜索空间的BWP中。
本申请实施例中,还可以保持第一时间、第二时间与现有技术中的定义不变,即第一时间根据网络侧设备配置的省功耗偏移(PS_offset)确定,第二时间根据终端侧设备确定的第一偏移确定,但是在BWP切换时延内,检测到第一指示信息,则忽略第一指示信息,即不根据第一指示信息进行BWP切换,下面详细描述。
实施例三:
如图7所示,为本申请实施例提供的一种检测方法流程示意图。该方法包括:
步骤701:终端侧设备在DRX持续时间的起始时间之前的多个监测时机进行检测。
所述检测是指终端侧设备根据特定DCI format对备选PDCCH进行监测。备选PDCCH中可能存在所述特定DCI format,终端侧设备需要通过检测来确定备选PDCCH中是否存在所述特定DCI format。关于监测时机,可以参考前面的描述,在此不再赘述。
步骤702:若终端侧设备检测到来自网络侧设备的第一指示信息的时间,位于所述DRX持续时间的起始时间之前的第一时间段内,则忽略所述第一指示信息。
相应的,在第一时段内,终端侧设备接收到第二指示信息时,第二指示信息有效,终端侧设备根据第二指示信息,确定是否进行唤醒操作。
可选的,步骤702还可以替换为以下步骤:
若终端侧设备检测到来自网络侧设备的第一指示信息的监测时机的结束时间,位于所述DRX持续时间的起始时间之前的第一时间段内,则忽略所述第一指示信息。所述监测 时机的结束时间可以定义为所述监测时机所在时间单元的结束时间。
其中,所述第一指示信息用于指示所述终端侧设备进行BWP切换,所述第一时间段为所述终端侧设备被允许进行BWP切换的时间段。
相应的,终端侧设备检测到第一指示信息的时间,或者终端侧设备检测到第一指示信息的监测时机的结束时间,位于第一时间与所述第一时间段的起始时间(可以包括第一时间段的起始时间)之间,则可以根据所述第一指示信息进行BWP切换。所述监测时机的结束时间可以定义为所述监测时机所在时间单元的结束时间。
可选的,终端侧设备在检测到所述第一指示信息的监测时机的结束时间至DRX持续时间的起始时间内进行BWP切换。其中,终端侧设备可以将检测到所述第一指示信息的监测时机的结束时间,作为BWP切换的起始时间;或者终端侧设备可以将第一时间段的起始时间作为BWP切换的起始时间;或者终端侧设备可以将第一指示信息的最后一个监测时机的结束时间作为BWP切换的起始时间,如实施例1所述。
需要说明的是,所述第一指示信息是通过DCI format 2_6的DCI发送的,该DCI中还可以携带第二指示信息,第二指示信息可以是指前面描述的唤醒指示信息。第二指示信息用于指示所述终端侧设备是否在所述DRX持续时间的起始时间唤醒。
其中,所述多个监测时机位于第一时间至第二时间内。所述第一时间与所述第二时间均位于所述DRX持续时间的起始时间之前,所述第二时间位于所述第一时间与所述DRX持续时间的起始时间之间。所述第一时间为在所述DRX持续时间的起始时间之前,终端侧设备开始检测DCI format 2_6的DCI的时间;相应的,第二时间为终端侧设备最晚停止检测DCI format 2_6的DCI的时间,即在第二时间至所述DRX持续时间的起始时间之间,不要求所述终端侧设备检测DCI format 2_6的DCI。
进一步的,所述第一时间与所述DRX持续时间的起始时间之间的时长为网络侧设备配置的。举例来说,第一时间与所述DRX持续时间的起始时间之间的时长为前面描述的省功耗偏移(PS_offset)进行配置。
所述第二时间与DRX持续时间的起始时间之间的时长可以等于终端侧设备确定的第一偏移。
本申请实施例中,第一时间段与第一指示信息可以存在关联关系。具体的,所述第一指示信息可以用于指示在所述终端侧设备在至少一个小区中进行BWP切换,所述至少一个小区可以属于一个辅小区组。所述第一时间段的时长可以等于所述第一指示信息指示的所述至少一个小区对应的BWP切换时延。
进一步的,当终端侧设备被网络设备配置为在所检测到的特定DCI format中仅包含所述终端侧设备的第二指示信息而不包含所述终端侧设备的第一指示信息时,所述终端侧设备在第一时间和第二时间内检测特定DCI format,并根据检测到的特定DCI format的DCI中的第二指示信息确定是否在预设位置或者预配置位置启动DRX持续时间定时器;当终端侧设备被网络设备配置为在所检测到的特定DCI format中包含所述终端侧设备的第一指示信息和二指示信息时,所述终端侧设备在第一时间和第二时间内检测特定DCI format,并根据检测到的特定DCI format的DCI中的第二指示信息确定是否在预设位置或者预配置位置启动DRX持续时间定时器,并根据第一时间和第一时间段的起始时间之间检测到的特定DCI format的DCI中的第一指示信息进行BWP切换,忽略第一时间段的起始时间之 后检测到的特定DCI format的DCI中的第一指示信息。所述忽略第一指示信息,指终端侧设备不根据第一指示信息进行BWP切换。
举例来说,如图8所示,以时间单元为NR***中的时隙为例进行描述。终端侧设备可以从位于DRX持续时间的起始时间之前的第一时间至第二时间内进行检测。第一时间至DRX持续时间的起始时间之间包括4个时隙,第二时间至DRX持续时间的起始时间之间包括1个时隙。第一时间至第二时间包括3个时隙,分别为时隙1、时隙2以及时隙3。
终端侧设备在第一时间和第二时间内的时隙2检测到DCI,该DCI中包括两个第一指示信息,分别为指示信息A和指示信息B。指示信息A用于指示终端侧设备在辅小区组1中进行BWP切换,指示信息B用于指示终端侧设备在辅小区组2中进行BWP切换。
辅小区组1对应的BWP切换时延为1个时隙,辅小区组2对应的BWP切换时延为2个时隙,即指示信息A关联的第一时间段为时间段A,包括1个时隙;指示信息B关联的第一时间段为时间段B,包括3个时隙。
通过上面的描述可知,终端侧设备检测到的DCI位于指示信息B关联的第一时间段内,位于指示信息A关联的第一时间段之外。
由于DCI位于指示信息B关联的第一时间段内,因此终端侧设备可以忽略指示信息B,即不在辅小区组2中进行BWP切换。相应的,终端侧设备可以根据指示信息A,在辅小区组1中进行BWP切换。
需要说明的是,本申请实施例中,终端侧设备忽略第一指示信息指,终端侧设备认为接收到的第一指示信息是无效的,不进行特定的操作。进一步,忽略第一指示信息包括终端侧设备保持当前BWP保持不变。
进一步的,如果在所述第一时间段的开始时间之前,所述终端侧设备没有检测到所述第一指示信息,则在所述DRX持续时间的起始时间开始,存在以下两种情况:
情况1,使用没有配置了PDCCH搜索空间的BWP进行通信;
在情况1中,终端侧设备可以在DRX持续时间的起始时间之前,切换到没有配置PDCCH搜索空间的BWP中,例如切换到网络侧配置的first non dormant BWP中。
情况2,使用当前的BWP进行通信。
在情况2中,在DRX持续时间的起始时间之前,终端侧设备保持当前的BWP不变。
进一步的,本申请实施例中,由于终端侧设备可以忽略位于第一时间段内的第一指示信息,为此,第一种可能的实现方式中,网络侧设备可以不在第一时间段内发送第一指示信息。
第二种可能的实现方式中,位于所述第一时间段内的第一指示信息对应的比特位的取值可以为预设值,例如设置为0或者1。
第三种可能的实现方式中,位于所述第一时间段内的第一指示信息对应的比特位的取值与第二指示信息对应的比特位的取值相同,从而可以提升DCI format 2_6的DCI检测的可靠性。
第四种可能的实现方式中,位于所述第一时间段内的第一指示信息可以用于指示其它功能,例如可以指示DRX持续时间之后的最小K0(minimum K0),minimum K0是指下行调度DCI与其调度的物理下行共享信道(physical downlink shared channel,PDSCH)之 间的时间间隔。
需说明的是,如前所述,第一指示信息与第二指示信息通过相同的DCI发送,终端侧设备可以根据第二指示信息确定是否在DRX持续时间内唤醒。如果第二指示信息指示所述终端侧设备在所述DRX持续时间的起始时间唤醒,则终端侧设备可以开启定时器drx-onDurationTimer,具体可以参考现有技术中的描述,在此不再赘述。
