Abstract

本申请实施例提供一种下行控制信道的检测方法及装置、终端设备,可以达到调度灵活性与终端能耗的折中。该方法包括:终端设备获取第一信息;所述终端设备根据所述第一信息,在与所述第一信息对应的至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间上检测下行控制信道。

Description

一种下行控制信道的检测方法及装置、终端设备 技术领域
本申请实施例涉及移动通信技术领域,具体涉及一种下行控制信道的检测方法及装置、终端设备。
背景技术
在新无线(NR,New Radio)系统中,网络可以在每个下行带宽部分(BWP,Band Width Part)上配置多个控制资源集(CORESET,Control Resource Set),CORESET定义了一个时频域资源,具体地,在频域上规定了CORESET的频域大小以及在时域上规定了CORESET占用的连续符号的数目。与此同时,下一代基站(gNB,nextgeneration NodeB)还可以给每个CORESET关联1个或者多个搜索空间(Search Space),以此来决定用户设备(UE,User Equipment)按照什么时间周期来检测控制信道。其中,每一个Search Space需要关联到一个CORESET。
另一方面,在NR系统中,每个媒体接入控制实体(MAC entity)有一个非连续接收(DRX,Discontinuous Reception)配置,值得注意的是,DRX的配置参数(简称为DRX参数)适用于所有配置的CORESET和Search Space。在一个DRX周期(DRX cycle)内,如果UE处于唤醒状态,则UE需要盲检所有的物理下行控制信道(PDCCH,Physical Downlink Control Channel)可能的位置;如果在任何一个PDCCH可能的位置监测到PDCCH,且如果该PDCCH调度一个上行或者下行的新传数据,则会重启定时器—drx-InactivityTimer,从而延长处于唤醒状态的时长。
在目前的配置中,Search Space和CORESET都是通过RRC信令来配置,对于配置周期比较小的Search Space,UE需要频繁的盲捡PDCCH,导致终端能耗加大;对于配置周期比较长的Search Space,UE不需要频繁的盲捡PDCCH,但是可能会牺牲调度灵活性。

图2为本申请实施例提供的下行控制信道的检测方法的流程示意图,如图2所示,所述下行控制信道的检测方法包括以下步骤:
步骤201:终端设备获取第一信息。
本申请实施例中,所述终端设备可以是手机、平板电脑、笔记本、台式机、车载终端、可穿戴设备等任意能够与网络设备进行通信的设备。
本申请实施例中,终端设备的每个MAC实体有一个DRX配,包括一组DRX参数,在一实施方式中,所述一组DRX参数包括以下至少之一:
第一时间参数,所述第一时间参数用于确定所述DRX周期的起始时间;

第四时间参数,所述第四时间参数用于确定所述DRX周期对应的短周期时长;
第五时间参数,所述第五时间参数用于确定所述DRX周期对应的长周期时长。
不局限于,所述一组DRX参数还可以包括更多的参数,例如:drx-SlotOffset、drx-RetransmissionTimerDL、drx-RetransmissionTimerUL、drx-ShortCycleTimer、drx-HARQ-RTT-TimerDL、drx-HARQ-RTT-TimerUL。
进一步,对于上述方案中的第一时间参数,所述终端设备在所述DRX周期中处于唤醒状态对应的起始时间为基于所述一组DRX参数中的第一时间参数确定的第一时间。这里,唤醒状态的起始时间(也即第一时间)可以为任意的时间,在一个例子中,所述终端设备在所述DRX周期中处于唤醒状态对应的起始时间(也即第一时间)与所述搜索空间的周期的整数倍对应。例如:Search Space的周期配置为1个slot,假设所述终端设备在DRX周期中处于唤醒状态对应的起始时间可以是该Search Space的周期的4倍,那么,该终端设备需要在时隙0,4,8,…开始对PDCCH进行检测。
进一步,对于上述方案中的所述第二时间参数和/或所述第三时间参数和/或所述第四时间参数和/或所述第五时间参数,通过绝对时间长度(比如n毫秒)或者连续的时间单元的个数(比如m个PDCCH子帧)进行表示。这里,所述时间单元为子帧、或时隙、或符号、或短传输时间间隔(STTI)。
具体实现时,所述第一时间参数可以通过drx-StartOffset表示,所述第二时间参数对应的功能可以通过定时器drx-onDurationTimer实现,所述第三时间参数对应的功能可以通过定时器drx-InactivityTimer实现,所述四时间参数对应可以通过drx-ShortCycle表示,所述第五时间参数可以通过drx-LongCycle表示。
本申请实施例中,所述第一信息与所述至少一个控制资源集和/或所述至少一个搜索空间的对应关系由网络设备配置。
进一步,所述第一信息与一个控制资源集和所述一个控制资源集关联的部分搜索空间或全部搜索空间对应;或者,所述第一信息与多个控制资源集和所述多个控制资源集分别关联的部分搜索空间或全部搜索空间对应。
例如:假设CORESET1关联的SearchSpace为SS1、SS2,CORESET2关联的SearchSpace为SS3,CORESET3关联的SearchSpace为SS4、SS5、SS6,在一个例子中, 网络侧给终端设备配置的第一信息与CORESET1和SS1对应。在另一个例子中,网络侧给终端设备配置的第一信息与CORESET3和SS4、SS5、SS6对应。在又一个例子中,网络侧给终端设备配置的第一信息与CORESET1和SS1,以及CORESET2和SS3对应。
本申请实施例中,所述至少一个控制资源集包括多个控制资源集的情况下:所述多个控制资源集中的不同控制资源集配置在相同的带宽部分BWP上;或者,所述多个控制资源集中的不同控制资源集配置在不同的BWP上。
步骤202:所述终端设备根据所述第一信息,在与所述第一信息对应的至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间上检测下行控制信道。
本申请实施例中,所述第一信息为无线资源控制(RRC,Radio Resource Control)信令、或者下行控制信息(DCI,Downlink Control Information)信令、或者媒体接入控制控制单元(MAC CE,Media Access Control Control Element)、或者第一序列(可以是任意的序列)。
1)所述第一信息为RRC信令的情况,所述第一信息包括一组非连续接收DRX参数或多组DRX参数;所述终端设备根据所述一组DRX参数,在所述一组DRX参数对应的至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间上检测下行控制信道;或者,所述终端设备根据所述多组DRX参数,在所述多组DRX参数分别对应的至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间上检测下行控制信道。
这里,针对所述一组DRX参数或者所述多组DRX参数中的每一组DRX参数,所述终端设备根据所述一组DRX参数或者所述多组DRX参数中的每一组DRX参数,确定该组DRX参数对应的第一时间段,并在该第一时间段内,在与该组DRX参数对应的的至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间上检测下行控制信道,其中,所述第一时间段为所述终端设备在DRX周期中处于唤醒状态的时间段。
在一实施方式中,所述终端被配置有所述多组DRX参数的情况,所述终端确定处于激活状态的至少一组DRX参数,在所述处于激活状态的至少一组DRX参数分别对应的至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间上检测下行控制信道;和/或,所述终端确定处于去激活状态的至少一组DRX参数,在所述处于去激活状态的至少一组DRX参数分别对应的至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间上取消对下行控制信道的检测。这里,所述终端设备获取第二信息,所述第二信息用于确定需要激活的至少一组DRX参数,和/或,需要去激活的至少一组DRX参数。
上述方案中,所述多组DRX参数中的每一组DRX参数分别对应一个索引信息;其中,1)所述第二信息为DCI信令或者MAC CE,所述DCI信令或者所述MAC CE用于指示需要激活的至少一组DRX参数分别对应的索引信息,和/或,需要去激活的至少一组DRX参数分别对应的索引信息。或者,2)所述第二信息包括至少一个第二序列,所述至少一个第二序列中的每个所述第二序列与一组DRX参数的索引信息具有对应关系。
举个例子,网络侧通过DCI信令或者MAC CE向终端设备指示3个DRX index,分别为index1、index2、index3,其中,index1对应一组DRX参数S1,index2对应一组DRX参数S2,index3对应一组DRX参数S3,终端设备基于此,确定需要激活的三组DRX参数。
再举个例子,终端设备获取到某一种序列,该序列与一组DRX参数的DRX index有对应关系(如正交关系),终端设备基于该序列可确定一组DRX参数的DRX index, 从而确定需要激活或去激活的一组DRX参数,这里,是以一个序列为例进行解释,不局限于此,多个序列的情况与一个序列同理,通过多个序列可以确定出需要激活或去激活的多组DRX参数的DRX index,从而确定出需要激活或去激活的多组DRX参数。
本申请实施例的上述方案中,网络侧可以给终端配置一组DRX参数或者多组DRX参数;如果第一信息仅包括一组DRX参数,则网络侧可以通过RRC重配置消息来更改不同的DRX参数,使得终端能够监测不同的搜索空间;如果第一信息包括多组DRX参数,那么每一组DRX参数可以对应至少一个控制资源集和搜索空间。终端只在对应的一组DRX参数所决定的唤醒时段去监听对应的搜索空间里的控制信道。进一步,网络侧给终端配置多组DRX参数,以及每组DRX参数与搜索空间的对应关系的情况下,网络侧还可以通过MAC CE或者DCI激活或去激活一组或者多组DRX参数,如果某一组DRX参数去激活,则终端不需要监测对应的搜索空间的下行控制信道。
2)所述第一信息为DCI信令或者MAC CE的情况,所述第一信息包括第一指示信息,所述第一指示信息用于指示一组DRX参数的索引信息(也即需要激活的一组DRX参数的索引信息);所述终端设备根据所述一组DRX参数的索引信息,确定至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间对应的一组DRX参数;所述终端设备根据所述一组DRX参数,确定所述终端设备在DRX周期中处于唤醒状态的第一时间段,并在所述第一时间段内在所述至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间上检测下行控制信道。
3)所述第一信息为DCI信令或者MAC CE的情况,所述第一信息包括第二指示信息,所述第二指示信息用于指示至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间;所述终端设备在所述第二指示信息所指示的所述至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间上检测下行控制信道。
4)所述第一信息为第一序列的情况,所述第一序列与一组DRX参数具有对应关系;所述终端设备根据所述第一序列,确定至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间对应的一组DRX参数;所述终端设备根据所述一组DRX参数,确定所述终端设备在DRX周期中处于唤醒状态的第一时间段,并在所述第一时间段内在所述至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间上检测下行控制信道。
5)所述第一信息为第一序列的情况,所述第一序列与至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间具有对应关系;所述终端设备根据所述第一序列,确定至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间;所述终端设备在至少一个控制资源集和所述至少一个控制资源集关联的至少一个搜索空间上检测下行控制信道。
上述方案中,可以通过RRC信令直接配置一组DRX参数,然后基于该DRX参数监测对应的搜索空间上的下行控制信道。还可以通过DCI信令或者MAC CE配置一个指示信息,来指示需要激活的一组DRX参数,这里,终端预先获取多组DRX参数(可以通过RRC信令获取),接收到指示信息后,激活其中一组DRX参数,然后基于该DRX参数监测对应的搜索空间上的下行控制信道。还可以通过DCI信令或者MAC CE配置另一个指示信息,来指示需要监测的搜索空间,这里,终端预先获取一组DRX参数,接收到指示信息后,基于该DRX参数监测指示信息所指示的搜索空间上的下行控制信道。
具体地,一个DRX周期包括两个时间段,分别为On Duration(终端设备处于唤醒状态)和Opportunity for DRX(终端设备处于睡眠状态),其中,时间段On Duration在时间段Opportunity for DRX之前,终端设备在DRX周期的起始时间(基于第一时间参 数确定),开始对PDCCH进行检测,并在时间段On Duration内持续对PDCCH进行检测;1)如果所述终端设备成功解码到一个下行控制信道且该下行控制信道调度一个新传输的数据,则启动定时器drx-InactivityTimer(对应第三时间参数),在该定时器超时前,终端设备会持续维持处于唤醒状态,并对PDCCH进行检测,在定时器超时后,终端设备进入睡眠状态,直到下一个DRX周期的起始时间到来重新进入唤醒状态。2)如果所述终端设备未成功解码到一个下行控制信道且该下行控制信道调度一个新传输的数据,则在时间段On Duration结束时,终端设备进入睡眠状态,直到下一个DRX周期的起始时间到来重新进入唤醒状态。
以下通过具体应用示例对本申请实施例的技术方案进行举例说明。
应用示例一
参照图3,网络给一个UE的一个下行BWP上配置了两个CORESET,分别为CORESET1和CORESET2,每一个CORESET有一个关联的Search Space,CORESET1关联的Search Space的周期与CORESET2关联的Search Space的周期不同。
本示例中,CORESET2对应第一信息,即同一组DRX参数。所述一组DRX参数可以包括DRX周期的起始时间,UE在DRX周期的起始时间开始检测PDCCH,这里,该起始时间是Ssearch Space对应的周期的整数倍,比如Search Space的周期配置为1个slot,该起始时间是可以是周期的4倍,UE需要在0,4,8,…开始DRX周期。此外,网络设备可以通过动态信令(如DCI)向UE指示DRX周期的起始时间。
UE在时间段On Duration内持续对PDCCH进行检测;1)如果所述终端设备成功解码到一个下行控制信道且该下行控制信道调度一个新传输的数据,则启动定时器drx-InactivityTimer(对应第三时间参数),在该定时器超时前,终端设备会持续维持处于唤醒状态,并对PDCCH进行检测,在定时器超时后,终端设备进入睡眠状态,直到下一个DRX周期的起始时间到来重新进入唤醒状态。2)如果所述终端设备未成功解码到一个下行控制信道且该下行控制信道调度一个新传输的数据,则在时间段On Duration结束时,终端设备进入睡眠状态,直到下一个DRX周期的起始时间到来重新进入唤醒状态。
应用示例二
网络给一个UE配置两个CORESET,参照图4,分别为CORESET1和CORESET2,每个CORESET各关联一个Search Space,CORESET1关联的Search Space的周期与CORESET2关联的Search Space的周期不同。这里,不限定CORESET1和CORESET2是在一个相同的BWP上还是不同的BWP上。
本示例中,CORESET1和CORESET2对应不同的第一信息,即不同的一组DRX参数。终端在CORESET1对应的DRX周期的唤醒时间段内,只监测CORESET1相关联的Search Space上的PDCCH;终端在CORESET2对应的DRX周期的唤醒时间段内,只监测CORESET2相关联的Search Space上的PDCCH。
