If the PDCCH detection within the DRX duration does not detect any uplink or downlink data scheduling, the terminal equipment is in the DRX dormant state for all the time except the duration in the DRX cycle, and PDCCH detection is not performed to achieve the saving Electric purpose. If the terminal device detects newly transmitted uplink or downlink data scheduling during PDCCH detection, it starts or restarts the inactive timer.

  • WUS can also carry corresponding operation information of the terminal device after wake-up, such as partial bandwidth BWP switching, aperiodic CSI measurement report, etc.
  • WUS reduces the possibility of terminal equipment waking up to detect PDCCH, and can achieve the purpose of further power saving.

Description

一种无线通信的方法、终端设备、网络设备及网络系统
本申请要求于2019年4月30日提交中国专利局、申请号为201910365339.4、申请名称为“一种无线通信的方法、终端设备、网络设备及网络系统”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领域,更具体地涉及一种无线通信的方法、终端设备、网络设备及网络系统。
背景技术
在长期演进(long term evolution,LTE)系统和第五代接入系统标准新空口(new radio,NR)中,都引入了非连续接收(discontinuous reception,DRX)技术,在一定程度上节省了终端设备功耗。
DRX在时间上分为不同的DRX周期(DRX cycle),DRX周期内起始位置处是持续时间(on duration)。在DRX持续时间内,持续时间计时器计时,终端设备进行物理下行控制信道(physical downlink control channel,PDCCH)检测。如果在DRX持续时间内的PDCCH检测都没有检测到任何上行或下行数据调度,则终端设备在DRX周期内除了持续时间之外的时间,都处于DRX休眠的状态,不进行PDCCH检测,以达到省电目的。如果终端设备在进行PDCCH检测时检测到新传的上行或下行数据调度,则开启或重启非活跃计时器。在持续时间计时器或非活跃计时器或重传计时器计时等情况下,终端设备处于DRX活跃时间(active time),即在DRX活跃时间期间终端设备需要进行PDCCH检测。当持续时间计时器、非活跃计时器和重传计时器都停止计时的情况下,终端设备进入DRX休眠状态,不进行PDCCH检测。
在5G NR系统中,讨论的一个课题是降低终端设备功耗,其中的一个重要方向是唤醒信号(wake-up signal,WUS)。WUS的检测时机一般认为是DRX周期之前或DRX周期的起始位置。如果网络设备发送WUS且指示终端设备唤醒,则终端设备在对应的DRX持续时间唤醒,例如进行PDCCH检测;如果网络设备不发送WUS,或者发送WUS且指示终端设备不唤醒,则终端设备继续休眠,跳过该DRX周期的PDCCH检测。WUS除了携带简单的是否唤醒的信息,还可以携带唤醒后终端设备的相应操作信息,如部分带宽BWP切换、非周期CSI测量上报等。
WUS在DRX的基础上,减少了终端设备醒来检测PDCCH的可能性,可以达到进一步省电的目的。但是,终端设备被设置为在每个WUS的检测时机均进行WUS检测,这会增加终端设备的检测失败率。
发明内容
本申请提供一种无线通信的方法、终端设备、网络设备及网络系统,能够更加灵活地 进行WUS检测。
第一方面,确定第一类型的物理下行控制信道PDCCH的检测时机对应的检测条件参数,其中所述第一类型的PDCCH用于指示终端设备是否在非连续接收DRX周期对应的持续时间做PDCCH检测;根据所述检测条件参数确定终端设备是否在DRX周期的活跃时间内检测所述PDCCH。
第一类型的PDCCH用于唤醒终端设备进入DRX周期对应的持续时间,以唤醒终端设备开始进行PDCCH检测或者其他需要在DRX持续时间内执行的操作。第一类型的PDCCH可以是携带或承载WUS的PDCCH,或者可以称为WUS-PDCCH。在本申请说明书中,WUS-PDCCH的检测/处理也可以简称为WUS的检测/处理。
根据本申请实施例,终端设备可以根据WUS-PDCCH的检测条件参数判断是否在DRX周期的活跃时间内检测WUS-PDCCH,这样可以在活跃时间内更加灵活地检测WUS-PDCCH。
由于在活跃时间内,终端设备本身需要检测的PDCCH格式就已经比较多;WUS作为新增的一种PDCCH,会进一步加大终端设备的检测负担。如果在活跃时间内始终都需要检测WUS,则可能增大PDCCH的盲检测次数,导致在PDCCH的某个检测时机,超过终端设备可接受的盲检测次数,从而导致检测失败。
另一方面,如果终端设备在活跃时间内始终都不检测WUS,例如因为WUS的优先级低于其他PDCCH而始终不检测WUS,会导致终端设备不能及时接收到有效的WUS并执行相应的操作,增加了PDCCH译码时延,降低系统效率。
本申请实施例为WUS-PDCCH设置检测条件,并灵活地根据检测条件确定是否检测WUS-PDCCH,这样能够在终端资源允许时及时地执行WUS-PDCCH检测。
本申请实施例对WUS-PDCCH唤醒终端设备的具体机制不作限制。例如,终端设备可以通过两种方式被唤醒进行PDCCH检测,一种是终端设备检测到WUS-PDCCH就被唤醒,终端设备在DRX周期对应的持续时间醒来做PDCCH检测,终端设备未检测到WUS-PDCCH就表示不唤醒;另一种是终端设备检测到的WUS-PDCCH包含某个特定字段,这种字段指示终端设备在DRX周期对应的持续时间是否醒来做PDCCH检测。
结合第一方面,在第一方面的某些实现方式中,根据所述检测条件参数确定终端设备是否在DRX周期的活跃时间内检测第一类型的PDCCH包括:在第一类型的PDCCH检测时机对应的下行控制信息DCI的比特数小于或等于第一阈值时,终端设备在非连续接收DRX周期的活跃时间内检测第一类型的PDCCH。
根据本申请实施例,终端设备根据检测条件参数控制检测PDCCH的数量,使在某个检测时机的候选PDCCH数量不超过终端设备可接受的数量。
例如,PDCCH检测时机对应的下行控制信息DCI的比特数大于第一阈值,表示此时终端设备检测PDCCH的能力非常有限,在此情况下终端设备可以在DRX周期的活跃时间内不检测WUS-PDCCH。
结合第一方面,在第一方面的某些实现方式中,根据所述检测条件参数确定终端设备是否在非连续接收DRX周期的活跃时间内检测第一类型的PDCCH包括:在PDCCH检测时机对应的下行控制信息DCI的比特数小于或等于第一阈值,且PDCCH检测时机所在的时隙对应的检测的候选PDCCH个数小于或者等于第二阈值及PDCCH检测时机所在的时隙对应的不交叠的控制信号单元CCE个数小于或者等于第三阈值时,终端设备在非连 续接收DRX周期的活跃时间内检测所述PDCCH。
根据本申请实施例,终端设备根据检测条件参数控制检测WUS-PDCCH的数量,避免PDCCH译码时延过高。具体地,当上述阈值条件均不能满足时,表示此时终端设备检测PDCCH的能力非常有限,在此情况下,终端设备可以在DRX周期的活跃时间内不检测WUS-PDCCH。
应理解,在所述PDCCH检测时机对应的下行控制信息DCI的比特数大于第一阈值,或所述PDCCH检测时机所在的时隙对应的检测的候选PDCCH个数大于第二阈值或所述PDCCH检测时机所在的时隙对应的不交叠的控制信号单元CCE个数大于第三阈值时,终端设备在DRX周期的活跃时间内不检测所述PDCCH。
结合第一方面,在第一方面的某些实现方式中,所述检测条件参数为第一类型的PDCCH检测时机对应的DCI的比特数或格式,若所述比特数或所述格式与下列情况的任一种相同,则检测所述PDCCH:小区无线网络临时标识SI-RNTI或寻呼无线网络临时标识P-RNTI或随机接入无线网络临时标识RA-RNTI或临时小区无线网络临时标识TC-RNTI关联的DCI;DCI格式1_1;DCI格式0_1;DCI格式1_0。
根据本申请实施例,终端设备可以选取特定类型或特定比特数的WUS-PDCCH进行检测和译码。例如DCI格式1_1,该DCI格式是用于PDSCH调度的;DCI格式0_1,该DCI格式是用于PUSCH调度的;DCI格式1_0,该DCI格式是用于PDSCH调度的,且与用于PUSCH调度的DCI格式0_0的DCI比特数相同。这样,对于特定类型的WUS-PDCCH,终端设备可以优先保证这些类型的PDCCH进行检测和译码,避免PDCCH译码时延过高。
结合第一方面,在第一方面的某些实现方式中,上述第一阈值是4,所述第二阈值是44、36、22或20,所述第三阈值是56或48或32。
根据本申请实施例,根据所述搭载第一类型的PDCCH的载波的参数集索引取值不同时确定不同的判断条件,可以使终端设备在DRX周期的活跃时间内更加灵活检测第一类型的PDCCH。
结合第一方面,在第一方面的某些实现方式中,所述方法还包括:所述终端设备在DRX周期的活跃时间外,在第一时刻之前且离所述第一时刻的间隔小于第四阈值的时机检测所述PDCCH;如果检测到所述PDCCH,则所述终端设备根据唤醒信息执行对应操作,如果未检测到所述PDCCH,则终端设备休眠。
如果所述PDCCH携带不唤醒相关信息,则终端设备的所述对应操作可以包括指示不唤醒1个或n个DRX周期(n为大于等于2的整数)对应的操作,即在1个或n个DRX周期不醒来做PDCCH检测;如果所述PDCCH携带唤醒相关信息,则终端设备的所述对应操作可以包括以下一个或多个指示对应的操作:指示唤醒后的下行部分带宽BWP和/或上行部分带宽BWP(终端设备唤醒后切换到指示的下行BWP或上行BWP上),指示非周期CSI测量上报(终端设备唤醒后做非周期CSI测量上报),指示激活的搜索空间集合(终端设备唤醒后激活相应的搜索空间集合),指示需要做PDCCH检测的载波组合(终端设备唤醒后在相应的载波组合上做PDCCH检测)。应理解,终端设备可以只在第一时刻对应的时机检测所述PDCCH,在DRX周期的活跃时间外的其他时刻可以不检测所述PDCCH,终端设备可以休眠。
根据本申请实施例,通过在终端设备仅在DRX周期的活跃时间外的第一时刻对应的 时机检测所述PDCCH,其余时间均处于休眠状态,以达到节省能耗的目的。
结合第一方面,在第一方面的某些实现方式中,所述方法还包括:所述终端设备通过协议预定义的方式,或者通过从网络设备接收无线资源控制消息的方式,获得偏移时间信息;其中,所述第一时刻根据所述偏移时间信息与DRX持续时间确定。

根据本申请实施例的无线通信的方法,在第一类型的PDCCH的检测周期与DRX周期不相等时,终端设备可以根据偏移时间信息和对应的DRX持续时间确定第一时刻,可以在第一时刻对应的时机检测所述PDCCH,达到灵活应用所述PDCCH的目的。

具体实施方式
下面将结合附图,对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、LTE系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、未来的第五代(5th Generation,5G)系统或新无线(New Radio,NR)等。
图1是适用于本申请实施例的移动通信系统的架构示意图。
如图1所示,该移动通信系统100可以包括网络设备101和至少一个终端设备102。图1只是示意图,该通信系统中还可以包括其它网络设备,如还可以包括无线中继设备和无线回传设备,在图1中未画出。本申请的实施例对该移动通信系统中包括的网络设备和终端设备的数量和具体类型不做限定。
本申请实施例中的终端设备102可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation  orotocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字助手(personal digital assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network,PLMN)中的终端设备等,本申请实施例对此并不限定。
本申请实施例中的网络设备101可以是用于与终端设备通信的设备,该网络设备可以是全球移动通讯(global system of mobile communication,GSM)系统或码分多址(code division multiple access,CDMA)中的网络设备(base transceiver station,BTS),也可以是宽带码分多址(wideband code division multiple access,WCDMA)系统中的网络设备(NodeB,NB),还可以是LTE系统中的演进型网络设备(Evolutional NodeB,eNB或eNodeB),还可以是云无线接入网络(cloud radio access network,CRAN)场景下的无线控制器,或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等,本申请实施例并不限定。
PDCCH中承载的是下行控制信息(downlink control information,DCI),包含一个或多个终端设备上的资源分配和其他的控制信息。
搜索空间(search space)是某个聚合等级(aggregation level,AL)下候选PDCCH(PDCCH candidate)的集合。由于网络设备实际发送的PDCCH的聚合等级随时间可变,而且由于没有相关信令告知终端设备,终端设备需在不同聚合等级下盲检PDCCH,其中,待盲检的PDCCH称为候选PDCCH,某个聚合等级可以有多个候选PDCCH。终端设备会在搜索空间内对由控制信道单元(control-channel element,CCE)构成的所有候选PDCCH进行译码,如果循环冗余校验(cyclic redundancy check,CRC)通过,则认为所译码的PDCCH的内容对所述终端设备有效,并处理译码后相关信息。
在NR中,为了更好地控制盲检测下行控制信道的复杂度,网络设备可为终端设备配置一个或多个搜索空间集合(search space set,SS set),其中,每个搜索空间集合包括一个或多个聚合等级的搜索空间。即搜索空间集合包括一个或多个聚合等级,以及对应每个聚合等级的候选PDCCH的数量。
在时域上,终端设备以一定的时间间隔检测搜索空间集合中的候选PDCCH,因此对于每个搜索空间集合会配置一些时域配置信息,包括:
检测周期:检测搜索空间集合的时间间隔,单位为时隙(slot);
检测时机:检测周期中检测PDCCH的时机;
时隙数量:连续检测搜索空间集合的时隙数量,且时隙数量小于检测周期的取值。
目前WUS已经确定基于PDCCH来设计(又称为WUS-PDCCH),即WUS是新增的一种PDCCH,因此可以通过DCI携带更多信息。其中,WUS携带有唤醒信息,现有技术中的唤醒信息除了是否唤醒的简单操作,还可以指示如下的不唤醒相关操作:
可选地,可以指示不唤醒n个DRX周期,n为大于等于2的整数。
或者,WUS还可以指示如下的一个或多个唤醒相关信息:
可选地,可以指示唤醒后的下行部分带宽(band width part,BWP)和/或上行BWP。
可选地,可以指示非周期信道状态信息(channel state information,CSI)测量上报(包括指示非周期信道状态信息参考信号(CSI reference signal,CSI-RS)的时频资源和上报CSI报告的上行时频资源)。
可选地,可以指示激活SS set组合。
可选地,可以指示需要做PDCCH检测的载波组合。
可选地,WUS既可以是发送给一个终端设备的,也可以是发送给由多个终端设备组成的一组终端设备的。
如果终端设备被设置为始终进行WUS检测,例如在活跃时间内和活跃时间外都进行WUS检测,增加了终端设备的检测失败率。具体地,在活跃时间内和活跃时间外都进行WUS检测,使得WUS除了在活跃时间外能起到的指示终端设备是否唤醒的作用,还可能在活跃时间内用于指示终端设备的相应操作。由于在活跃时间内,终端设备本身需要检测的PDCCH格式就已经比较多。而WUS是新增的一种PDCCH,可能增大PDCCH的盲检测次数,导致在PDCCH的某个检测时机,超过终端设备可接受的盲检测次数。
图2是一种无线通信的方法的示意性流程图。图2的方法可以由图1的终端设备102执行。
S201,终端设备确定第一类型的PDCCH的检测时机对应的检测条件参数,第一类型的PDCCH用于唤醒终端设备进入DRX周期对应的持续时间。
第一类型的PDCCH用于唤醒终端设备进入DRX周期对应的持续时间,以唤醒终端设备开始进行PDCCH检测或者其他需要在DRX持续时间内执行的操作。第一类型的PDCCH可以是携带或承载WUS的PDCCH,或者可以称为WUS-PDCCH。在本申请说明书中,WUS-PDCCH的检测/处理也可以简称为WUS的检测/处理。
可选地,终端设备可以通过两种方式被唤醒进行检测第一类型的PDCCH可以通过两种方式唤醒终端设备进行PDCCH检测,一种是终端设备检测到WUS-PDCCH就被唤醒,终端设备在DRX周期对应的持续时间醒来做PDCCH检测,终端设备未检测到WUS-PDCCH就表示不唤醒;另一种是终端设备检测到的WUS-PDCCH包含某个特定字段,这种字段指示终端设备在DRX周期对应的持续时间是否醒来做PDCCH检测。
S202,终端设备根据检测条件参数确定终端设备是否在DRX周期的活跃时间内检测第一类型的PDCCH。
根据本申请实施例,终端设备可以根据WUS-PDCCH的检测条件参数判断是否在DRX周期的活跃时间内检测WUS-PDCCH,这样可以在活跃时间内更加灵活地检测WUS-PDCCH。
例如,终端设备通过网络设备配置的第一类型的PDCCH的检测周期、检测时机、检测时频资源,第一类型的PDCCH携带的DCI的比特数大小,以及DRX配置等检测条件参数,来确定是否检测第一类型的PDCCH。
可选地,检测条件参数可以与第一类型的PDCCH的检测时机和/或第一类型的PDCCH的携带信息格式和资源占用量关联。
例如,检测条件参数可以是PDCCH检测时间对应的比特数,或者PDCCH检测时机所在的时隙对应的检测的候选PDCCH的个数,或者PDCCH检测时机所在的时隙对应的不交叠的控制信号单元(control-channel element,CCE)的个数等。
一个实施例中,检测条件参数为第一类型的PDCCH检测时机对应的DCI的比特数。例如,在第一类型的PDCCH检测时机对应的DCI的比特数小于或等于第一阈值时,终端设备在非连续接收DRX周期的活跃时间内检测所述PDCCH。
应理解,在第一类型的PDCCH检测时机对应的DCI的比特数大于第一阈值时,终端 设备在非连续接收DRX周期的活跃时间内不检测所述PDCCH。
或者,例如,在WUS-PDCCH检测时机对应的下行控制信息DCI的比特数小于或等于第一阈值,且第一类型的PDCCH检测时机所在的时隙对应的检测的候选WUS-PDCCH个数小于或者等于第二阈值及WUS-PDCCH检测时机所在的时隙对应的不交叠的CCE个数小于或者等于第三阈值时,终端设备在DRX周期的活跃时间内检测WUS-PDCCH。
应理解,在WUS-PDCCH检测时机对应的下行控制信息DCI的比特数大于第一阈值,或WUS-PDCCH检测时机所在的时隙对应的检测的候选PDCCH个数大于第二阈值或WUS-PDCCH检测时机所在的时隙对应的不交叠的CCE个数小于或者等于第三阈值时,终端设备在非连续接收DRX周期的活跃时间内不检测WUS-PDCCH。
其中,WUS-PDCCH的检测时机对应的DCI可以是WUS-PDCCH携带的DCI。
其中,候选PDCCH为待盲检测的PDCCH,包括WUS-PDCCH或者其他类型的PDCCH。如果该PDCCH检测时机对应所在的时隙没有发生PDCCH发送,则终端设备需要完成所有的候选PDCCH的检测。
对于不同候选PDCCH的两个CCE,不交叠的定义为:CCE对应不同的CORESET索引,或者,CCE对应的接收候选各自的PDCCH起始符号不同。
可选地,所述第二阈值可以根据表1中的值确定。
表1
Figure PCTCN2020087940-appb-000001
其中,μ为发送PDCCH的载波的参数集(numerology)索引,μ=0,1,2,3分别对应发送PDCCH的载波的子载波间隔为15kHz,30kHz,60kHz,120kHz。

可选地,第一阈值可以是4,第二阈值可以是44、36、22或20,第三阈值可以是56或48或32。例如,可以按照上表1-2的方式设置三个阈值。
可选地,检测条件参数可以是PDCCH检测时机对应的DCI的格式,若DCI的格式与下列情况的任一种格式相同,则检测PDCCH:
小区无线网络临时标识(system information radio network temporary identity,SI-RNTI)或寻呼无线网络临时标识(paging radio network temporary identity,P-RNTI)或随机接入无线网络临时标识(random access radio network temporary identity,RA-RNTI)或临时小区无线网络临时标识(temporary cell radio network temporary identity,TC-RNTI)关联的DCI;

SI-RNTI或P-RNTI或RA-RNTI或TC-RNTI关联的DCI;
DCI格式1_1;
DCI格式0_1;
DCI格式1_0。
S203是可选的步骤,例如可以在检测到WUS-PDCCH时才执行。在S203中,终端设备可以根据在DRX周期的活跃时间内检测到的WUS-PDCCH所携带的指示信息执行相关操作。
可选地,如果终端设备在DRX周期的活跃时间内检测到第一类型的PDCCH,且第一类型的PDCCH内包含对应活跃时间外的不唤醒指示,则终端设备只在主载波检测PDCCH,不在辅载波检测PDCCH。
可选地,如果终端设备在DRX周期的活跃时间内检测到第一类型的PDCCH,且第一类型的PDCCH内包含对应活跃时间外的不唤醒指示,则终端设备去激活第一搜索空间集合SS set组,其中,第一SS set组与所述PDCCH不关联。这里不关联的含义是,第一SS set组中,不包括配置检测所述PDCCH的SS set。
可选地,如果终端设备在DRX周期的活跃时间内检测到第一类型的PDCCH,且第一类型的PDCCH内包含对应活跃时间外的不唤醒指示,则终端设备根据不唤醒指示,在多于一个PDCCH检测跳过时长中的一个PDCCH检测跳过时长,跳过PDCCH检测。
可选地,终端设备对于上述包含对应活跃时间外的不唤醒指示的第一类型的PDCCH的操作可以是网络设备发送的RRC消息携带的也可是协议预定义的。
可选地,如果终端设备在DRX周期的活跃时间内检测到第一类型的PDCCH,且第一类型的PDCCH内包含触发终端设备做非周期信道状态信息CSI测量的唤醒指示,则终端设备不测量CSI和/或不发送CSI报告。
可选地,终端设备的上述行为可以是协议预定义的,也可以是通过网络设备发送的无线资源控制消息获取的。
图3是一种无线通信方法的示意性交互图。图3的方法可以由图1的网络设备101和终端设备102执行。
S301,网络设备可以向终端设备发送无线资源控制(radio resource control,RRC)消息,RRC消息可以携带以下一个或多个信息:
第一类型的PDCCH的检测周期、检测时机及检测时频资源等相关参数;或者
DRX周期、DRX持续时间等DRX相关配置参数。
可选地,第一类型的PDCCH的检测周期与DRX周期由无线资源控制消息中的不同参数配置。
可选地,可以发送一个或多个载波。如果发送的载波数大于一个,则这些载波中有一个主载波,其余载波为辅载波。
可选地,可以对每个载波都配置一个或多个下行BWP和/或上行BWP。
可选地,可以对每个下行BWP,配置一个或多个可以被激活/去激活的SS set,组成半持续性SS set组合,所述半持续性SS set组合中不包括关联WUS的SS set。
其中,可以由SS set确定其对应的PDCCH的检测周期、检测时机,更好地控制候选PDCCH的复杂度。
可选地,在多于一个PDCCH检测跳过时长中的一个PDCCH检测跳过时长,跳过PDCCH检测。
非周期的CSI触发状态列表,以及专门用于反馈WUS触发的非周期CSI报告的上行信道资源。
所述CSI触发状态列表中的每个触发状态,关联CSI报告类型、CSI-RS资源(可以包括用于信道测量和/或干扰测量的CSI-RS)等。
可选地,所述上行信道资源,时域位置在WUS检测时机与对应的DRX持续时间之间。
可选地,所述上行信道资源可以为PUSCH或者PUCCH,其中,PUCCH的格式可以为PUCCH格式2、PUCCH格式3或PUCCH格式4。
S302,终端设备确认配置信息。
第一类型的PDCCH用于唤醒终端设备进入DRX周期对应的持续时间,以唤醒终端设备开始进行PDCCH检测或者其他需要在DRX持续时间内执行的操作。第一类型的PDCCH可以是携带或承载WUS的PDCCH,或者可以称为WUS-PDCCH。在本申请说明书中,WUS-PDCCH的检测/处理也可以简称为WUS的检测/处理。
由于WUS-PDCCH的配置信息和DRX周期的配置信息可以是由无线资源控制消息中的不同参数配置,所以WUS-PDCCH的检测周期可以等于DRX周期,也可以不等于DRX周期。
其中,通过给配置WUS-PDCCH对应的DCI格式关联一个SS set和控制资源集合(control resource set,CORESET),由SS set确定WUS-PDCCH的检测周期、检测时机, 由CORESET确定WUS-PDCCH的检测时频资源。
例如,DRX周期可以是第一类型的PDCCH检测周期的整数倍,或者,第一类型的PDCCH检测周期可以是DRX周期的整数倍。
可选地,WUS-PDCCH可以是发给一组多个终端设备的,也可以是发给一个终端设备的。
网络设备通过RRC消息,由于RRC消息可以携带DRX周期及第一类型的PDCCH的检测周期等相关参数。终端设备可以根据不同的RRC消息,确认不同的配置信息,例如网络设备可以根据需要配置不同的第一类型的PDCCH检测周期,可以使第一类型的PDCCH使用更灵活。
图4是网络设备发送给一组多个终端设备的WUS-PDCCH所携带的DCI中的不同比特块的示意图。
如图4所示,是对于发送给一组多个终端设备的WUS-PDCCH所携带的DCI中的不同比特块,还需要配置在WUS-PDCCH所携带的DCI中对应该终端设备的比特块位置和比特块的比特数,用于一组多个终端设备中的每一个终端设备可以在WUS-PDCCH携带的所有DCI中读取其对应的WUS-PDCCH所携带的DCI。
WUS-PDCCH所携带的DCI的索引含义列表,可以用于指示终端设备在休眠状态下检测到WUS-PDCCH时,可以进行唤醒或不唤醒行为。列表中,一个或多个索引取值对应上述步骤S101中配置的一个或多个配置参数的相关行为。
示例性的,对于比特数为2的索引,可以有如下表一的WUS-PDCCH所携带的DCI索引含义列表。
表3给出了示例性的一些可能,但索引取值及对应的终端设备执行的操作并不进行限定。
表3
Figure PCTCN2020087940-appb-000005
可选地,还可以配置活跃时间内WUS-PDCCH所携带的DCI索引含义列表(后面分别简称为表3和表4,其中,表3对应终端设备在休眠状态检测WUS-PDCCH所携带的DCI的内容解读,表4对应终端设备在活跃时间内检测WUS-PDCCH所携带的DCI的内容解读)。
示例性的,对于比特数为2的索引,可以有如下表4的WUS-PDCCH所携带的DCI索引含义列表:
表4
Figure PCTCN2020087940-appb-000006
表4给出了示例性的一些可能,但索引取值及对应的终端设备执行的操作并不进行限定。
例如,以下的一个或多个内容,表3可以配置,表4不可以配置:
不唤醒1个DRX周期;
不唤醒n个DRX周期(n为大于等于2的整数);
触发非周期CSI-RS测量。
这是因为,在活跃时间,可能缺乏专门用于反馈WUS-PDCCH触发的非周期CSI报告的上行信道资源(该上行信道资源的时域位置在WUS-PDCCH检测时机与对应的DRX持续时间之间);并且,活跃时间是有其他方式触发非周期CSI测量上报,不需要触发WUS-PDCCH专用的非周期CSI测量和/或上报。
再例如,以下的一个或多个内容,表4可以配置,表3不能配置:
在多于一个PDCCH检测跳过时长中的一个PDCCH检测跳过时长,跳过PDCCH检测。
由于WUS-PDCCH的检测周期和DRX周期可以是单独配置的,所以WUS-PDCCH的检测周期和DRX周期可以不相等。例如,DRX周期可以是WUS-PDCCH的检测周期的整数倍,或者,也可以不是WUS-PDCCH的检测周期的整数倍。
为了减少终端设备醒来检测PDCCH的可能性,达到进一步省电的目的,终端设备只需要在WUS-PDCCH的检测周期的时刻醒来进行WUS-PDCCH检测。
可选地,当DRX周期大于WUS-PDCCH的检测周期时,可以使终端设备在不对应DRX周期唤醒WUS-PDCCH的检测时机。例如如果处于活跃时间之外,则终端设备不检测WUS-PDCCH,进一步达到省电的目的。
可选地,当WUS-PDCCH的检测周期和DRX周期不相等时,网络设备发送的RRC消息还可以包括偏移时间信息。偏移时间信息用于指示终端设备唤醒进行WUS-PDCCH检测。
图5和图6是WUS-PDCCH的检测周期和DRX周期不相等时的示意图。结合图5和图6的实施例,描述终端设备根据偏移时间信息唤醒的示例方式。
当WUS-PDCCH的检测周期和DRX周期不相等时,终端设备可以通过协议预定义的方式,或者通过从网络设备接收无线资源控制消息的方式,获得偏移时间信息。
终端设备根据偏移时间信息与DRX周期或DRX持续时间来确定第一时刻。其中,所 述偏移时间信息可以对应等于0或大于0的偏移时间。
如图5所示,如果偏移时间等于0,则第一时刻为DRX周期的起始时刻,也即该DRX周期的持续时间的起始时刻。其中,501为不对应DRX周期唤醒的WUS-PDCCH的检测时机,而502为对应DRX周期唤醒的WUS-PDCCH的检测时机。
如图6所示,如果偏移时间大于0,第一时刻根据偏移时间信息和对应的DRX持续时间确定。终端设备在DRX周期的活跃时间外,在第一时刻之前且离第一时刻的间隔小于第四阈值的时机检测WUS-PDCCH,其中,第四阈值用于确定在第一时刻之前且离第一时刻最近的第一类型的PDCCH的检测时机。
第一类型的PDCCH的检测周期和DRX周期不相等,如果偏移时间大于0,可以根据DRX持续时间和偏移时间信息确定对应DRX周期的WUS-PDCCH的检测时机,如图6所示,确定的WUS-PDCCH的检测时机为602。
可选地,当第一类型的PDCCH的检测周期是DRX周期的整数倍时,偏移时间信息可以用于指示终端设备在其中不与DRX周期对应的WUS-PDCCH的检测周期,达到节约能耗的目的。
S303,网络设备向终端设备发送第一类型的PDCCH。
S304,终端设备检测到第一类型的PDCCH。
如果终端处不在活跃时间内,可以通过以下步骤确定是否检测WUS-PDCCH:
可选地,终端设备在DRX周期的活跃时间外,在第一时刻之前且离所述第一时刻的间隔小于第四阈值的时机检测WUS-PDCCH;如果检测到WUS-PDCCH,则终端设备根据唤醒信息执行对应操作,如果未检测到WUS-PDCCH,则终端设备休眠。
可选地,终端设备从网络设备接收偏移时间信息;其中,第一时刻根据偏移时间信息与DRX持续时间确定。
可选地,在检测WUS-PDCCH之前,还需要确定WUS-PDCCH的检测周期与DRX周期不相等。
可选地,终端设备不在上述WUS-PDCCH的检测时机或者DRX周期的活跃时间内,则终端设备可以不检测WUS-PDCCH。
S305,网络设备向终端设备发送的RRC消息还可以包括第一类型指示信息,第一类型指示信息可以指示终端设备在DRX周期的活跃时间检测WUS-PDCCH时,则可以根据第一类型指示信息进行以下操作:
如果终端设备在DRX周期的活跃时间内检测到WUS-PDCCH,且第WUS-PDCCH内包含对应活跃时间外的不唤醒指示,则终端设备只在主载波检测PDCCH,不在辅载波检测PDCCH。
或者,如果终端设备在DRX周期的活跃时间内检测到WUS-PDCCH,且WUS-PDCCH内包含对应活跃时间外的不唤醒指示,则终端设备去激活第一搜索空间集合SS set组,其中,第一SS set组与WUS-PDCCH不关联。这里不关联的含义是,第一SS set组中,不包括配置检测WUS-PDCCH的SS set。
可选地,如果终端设备在DRX周期的活跃时间内检测到WUS-PDCCH,且WUS-PDCCH内包含对应活跃时间外的不唤醒指示,则终端设备根据不唤醒指示,在多于一个PDCCH检测跳过时长中的一个PDCCH检测跳过时长,跳过PDCCH检测。
可选地,终端设备对于上述包含对应活跃时间外的不唤醒指示的WUS-PDCCH的操 作可以是网络设备发送的RRC消息携带的,也可是协议预定义的。
可选地,如果终端设备在DRX周期的活跃时间内检测到WUS-PDCCH,且WUS-PDCCH内包含触发终端设备做非周期信道状态信息CSI测量的唤醒指示,则终端设备不测量CSI和/或不发送CSI报告。
可选地,如果终端设备配置了表4或者处于休眠状态,则按WUS-PDCCH索引配置表3检测WUS-PDCCH;如果处于活跃时间,则按照WUS-PDCCH索引配置表4检测WUS-PDCCH。
可选地,如果WUS-PDCCH为发给一组多个终端设备,则终端设备在S305时,需要先在所有的WUS-PDCCH检测时机对应的DCI中找到自己对应的比特块的WUS-PDCCH检测时机对应的DCI。
可选地,终端设备的上述行为可以是协议预定义的,不需要第一类型指示信息进行定义。
