技术领域
本公开涉及通信技术领域,尤其是指一种物理下行控制信道PDCCH的检测方法、装置及终端。
背景技术
在NR(New Radio,新空口)系统中,连接态的用户配置了DRX(Discontinuous Reception,非连续接收),节能PDCCH(Physical Downlink Control Channel,物理下行控制信道)可指示每个DRX周期是否需要激活。将通知终端进行后续一段时间PDCCH检测的PDCCH信令称为节能PDCCH(Power Saving-PDCCH,PS-PDCCH),将用户在后续一段时间不需要进行PDCCH检测称为睡眠,进行PDCCH检测称为醒来。
传输节能PDCCH的资源块中含有DMRS(DeModulation Reference Signal,解调参考信号),可通过对DMRS的序列检测判断PDCCH是否传输。DMRS序列检测和PDCCH译码相比较为简单,如果DMRS检测通过,再进行针对PDCCH的信道估计和盲检,如果没有检测到DMRS,则认为基站没有传输PDCCH,不进行后续信道估计和盲检,这样可以减少PDCCH盲检次数,节约用户功耗。
如上述所述,利用节能PDCCH DMRS进行存在检测的一种方式是将节能PDCCH相关信息引入到DMRS加扰的初始化种子中,如对节能PDCCH进行加扰的PS-RNTI(Power Saving-Radio Network Temporary Identity,节能无线网络临时标识)配置称为节能PDCCH DMRS的参数。
利用节能PDCCH DMRS进行PDCCH存在检测有个假设,就是基站存在不发送节能PDCCH的情况,基站不发送节能PDCCH可以表示用户睡眠,那么发送节能PDCCH指示用户醒来,这样当用户漏检节能PDCCH时,用户也会认为基站发送了睡眠,从而漏检了后续DRX周期中的PDCCH。

附图说明

图2表示本公开实施例提供的物理下行控制信道PDCCH的检测装置的结构示意图;
图3表示本公开实施例提供的终端的结构示意图。
具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
如图1所示,本公开实施例提供一种物理下行控制信道PDCCH的检测方法,应用于终端,包括:
步骤11,在网络侧设备配置的PDCCH检测机会上进行解调参考信号DMRS的检测;
步骤12,进行节能PDCCH盲检;
步骤13,根据所述DMRS的检测结果或所述节能PDCCH的盲检结果,在后续的至少一个非连续接收DRX周期中进行PDCCH检测;和/或,根据所述DMRS的检测结果和/或所述节能PDCCH的盲检结果,对DRX持续时间定时器、信道状态信息CSI以及信道探测参考信号SRS中至少一项进行预设处理。
作为一个可选实施例,并不限定步骤11和步骤12的执行顺序,可以先执行步骤11,再执行步骤12;也可以先执行步骤12,再执行步骤11;或者,通知执行步骤11和步骤12。
进一步的,作为又一个可选实施例,步骤12包括:
若DMRS的检测值大于预设门限值,则进行节能PDCCH盲检;否则, 不进行节能PDCCH盲检。
换言之,终端可以先进行DMRS检测,如果DMRS的检测值大于预设门限值,则进行节能PDCCH盲检,否则不进行节能PDCCH盲检。所述预设门限值可以标准定义,或者通过RRC信令配置。这样一方面可以降低节能PDCCH盲检的个数,从而节约功耗;另一方面可以降低节能PDCCH的漏检概率。如果节能PDCCH的循环冗余校验码CRC校验通过,则所述终端在节能PDCCH DMRS之后的DRX周期中,进行PDCCH检测并对DRX持续时间定时器、信道状态信息CSI以及信道探测参考信号SRS中至少一项进行预设处理。如果节能PDCCH的循环冗余校验码CRC校验未通过,则所述终端在节能PDCCH DMRS之后的DRX周期中,不进行PDCCH检测,DRX持续时间定时器不计时,信道状态信息CSI以及信道探测参考信号SRS都不被触发。
作为一个可选实施例,步骤13包括:
若所述DMRS的检测值大于预设门限值,所述终端在后续的至少一个非连续接收DRX周期中进行PDCCH检测。
作为又一个可选实施例,步骤13包括:
若所述节能PDCCH的循环冗余校验码CRC校验通过,所述终端在后续的至少一个非连续接收DRX周期中进行PDCCH检测。
作为另一个可选实施例,步骤13包括:
若所述DMRS的检测值大于预设门限值,且所述节能PDCCH的CRC校验通过,所述终端在后续的至少一个非连续接收DRX周期中进行PDCCH检测。
作为又一个可选实施例,终端可以进行PDCCH DMRS检测,并且进行PDCCH盲检,则步骤13包括:
若所述节能PDCCH的循环冗余校验码CRC校验未通过,并且DMRS的检测值大于预设门限值,在节能PDCCH DMRS之后的DRX周期中,对DRX持续时间定时器、信道状态信息CSI以及信道探测参考信号SRS中至少一项进行预设处理。
进一步,步骤13还可以包括:
若所述节能PDCCH的循环冗余校验码CRC校验未通过,在节能PDCCH DMRS之后的DRX周期中,所述终端进行PDCCH检测并对DRX持续时间定时器、信道状态信息CSI以及信道探测参考信号SRS中至少一项进行预设处理;
或者,步骤13包括:
若DMRS的检测值大于预设门限值,在节能PDCCH DMRS之后的DRX周期中,所述终端进行PDCCH检测并对DRX持续时间定时器、信道状态信息CSI以及信道探测参考信号SRS中至少一项进行预设处理。
例如,DMRS的检测值大于预设门限值,或者节能PDCCH的循环冗余校验码CRC校验通过,则所述终端在节能PDCCH DMRS之后的DRX周期中,进行PDCCH检测,或者并对DRX持续时间定时器、信道状态信息CSI以及信道探测参考信号SRS中至少一项进行预设处理。
再例如,DMRS的检测值不大于预设值,并且节能PDCCH的循环冗余校验码CRC校验未通过,则不进行PDCCH检测,并不启动DRX持续时间定时器、不触发信道状态信息CSI上报以及信道探测参考信号SRS传输。
又例如,DMRS的检测值大于预设值,并且节能PDCCH的循环冗余校验码CRC校验通过,则进行PDCCH检测,并启动DRX持续时间定时器、根据NR标准进行信道状态信息CSI上报以及信道探测参考信号SRS传输。
由于按照DMRS检测的虚警概率(如1%)要高于PDCCH检测的虚警概率,如果DMRS检测到有节能PDCCH发送,实际上网络侧没有发送节能PDCCH。当虚警时,如果用户在节能PDCCH指示的DRX周期进行CSI上报,或者发送SRS就会和基站在相同资源上调度的数据发生冲突。考虑到这种情况,本公开实施例中终端在节能PDCCH指示的DRX周期中进行PDCCH检测相关操作,当用户检测到有PDCCH传输,说明在DRX周期之前的节能PDCCH中指示用户醒来,DMRS并未虚警,则在后续时间可以进行周期以及半持续CSI的上报。当用户检测到有PDCCH传输,系统会启动DRX去激活定时器(drx-InactivityTimer),则可以让终端仅仅DRX去激活定时器启动时间进行CSI上报。
本公开实施例中,DMRS检测结果指示节能PDCCH存在,但是节能 PDCCH的CRC检验未通过的情况,也称之为DMRS检测结果和节能PDCCH检测结果不一致的情况;针对上述情况,本公开实施例规定了后续的相关处理,包括:在节能PDCCH DMRS之后的DRX周期中,所述终端进行PDCCH检测并对DRX持续时间定时器、CSI以及SRS中至少一项进行预设处理。本公开实施例提供的PDCCH的检测方法可以降低PDCCH楼漏检概率,并且避免了DMRS检测虚警时,CSI上报和SRS发送所带来的资源冲突问题,同时保证CSI的信息及时上报。
可选的,本公开的上述实施例中步骤12包括:
若DMRS的检测值大于预设门限值,则进行节能PDCCH盲检;否则,不进行节能PDCCH盲检。
作为一个可选实施例,步骤13中所述终端进行PDCCH检测,包括:
所述终端对通过目标标识进行加扰的PDCCH进行检测;其中,所述目标标识包括下述至少一项:
小区-无线网络临时标识C-RNTI;
配置调度-无线网络临时标识CS-RNTI;
中断无线-网络临时标识INT-RNTI;
时隙格式指示-无线网络临时标识SFI-RNTI;
半持续-信道状态信息-无线网络临时标识SP-CSI-RNTI;
发射功率控制-物理上行控制信道-无线网络临时标识TPC-PUCCH-RNTI;
发射功率控制-物理上行共享信道-无线网络临时标识TPC-PUSCH-RNTI;
发射功率控制-信道探测参考信号-无线网络临时标识TPC-SRS-RNTI。
需要说明的是,本公开实施例提供多种对DRX持续时间定时器、信道状态信息CSI以及信道探测参考信号SRS中至少一项进行预设处理的方式,下面分别进行描述。
方式一:即所述对DRX持续时间定时器(即drx-onDurationTimer)、信道状态信息CSI以及信道探测参考信号SRS中至少一项进行预设处理,包括:
启动所述DRX持续时间定时器;若CSI掩码(CSI-mask)为1,所述终端在DRX激活期对应的时间内不进行CSI的上报;若CSI掩码为0,所述终端在DRX去激活定时器(drx-InactivityTimer)运行对应的时间内进行CSI的 上报;
或者,
启动所述DRX持续时间定时器,所述终端在DRX去激活定时器运行对应的时间内进行SRS的传输。
此方式中的CSI的上报包括:周期CSI的上报和/或半持续CSI的上报。
可选的,本公开实施例中,当CSI-mask为1时,不允许进行CSI上报;而当CSI-mask为0时,仅允许在DRX去激活定时器运行对应的时间内进行CSI上报。或者,本公开实施例仅允许在DRX去激活定时器运行对应的时间内进行SRS的传输。
该方式可以降低了PDCCH的误检概率,CSI上报利用drx-InactivityTimer,采用较为简单的方法,避免了DMRS检测虚警上报CSI带来的资源冲突,并且能够及时上报CSI的信息。
方式二:即所述对DRX持续时间定时器、信道状态信息CSI以及信道探测参考信号中至少一项进行预设处理,包括:
启动所述DRX持续时间定时器,若CSI掩码为1,所述终端在DRX持续时间定时器运行对应的时间内进行CSI的上报;若CSI掩码为0,所述终端在DRX激活期对应的时间内进行CSI的上报;
或者,
启动所述DRX持续时间定时器,终端在DRX激活期对应的时间内进行SRS的传输。
此方式中的CSI的上报包括:周期CSI的上报和/或半持续CSI的上报。
可选的,本公开实施例中,当CSI-mask为1时,允许在DRX持续时间定时器运行对应的时间内进行CSI上报;而当CSI-mask为0时,允许在DRX激活期对应的时间内进行CSI上报。或者,本公开实施例仅允许在DRX激活期对应的时间内进行SRS的传输。
该方式可以降低PDCCH的误检概率,对标准的影响较小,适用于DMRS虚警概率的较低的情况。
方式三:即所述对DRX持续时间定时器、信道状态信息CSI以及信道探测参考信号中至少一项进行预设处理,包括:
启动所述DRX持续时间定时器,所述终端在DRX激活期对应的时间内不进行CSI的上报;
或者,
启动所述DRX持续时间定时器,所述终端在DRX激活期对应的时间内不进行SRS的传输。
本公开实施例中,终端在DRX激活期仅进行PDCCH检测,不进行CSI上报和SRS传输。
该方式可降低PDCCH的误检概率,对标准的影响较小,实现十分简单,对于在DRX激活期无法上报的周期CSI和/或半持续CSI,系统可以调度用户传输非周期CSI,从而获得CSI信息。
方式四:即所述对DRX持续时间定时器、信道状态信息CSI以及信道探测参考信号中至少一项进行预设处理,包括:
不启动所述DRX持续时间定时器,所述终端的媒体介入控制MAC层根据DRX持续时间定时器未启动进行CSI的上报和SRS的传输,所述终端的物理层根据高层配置的DRX参数维护DRX周期中的定时器。定时器的维护是为了保证终端在没有PDCCH传输时可以进入睡眠状态。
可选的,DRX周期中的定时器包含但不仅限于下述定时器:
DRX持续时间定时器(drx-onDurationTimer);DRX去激活定时器(drx-InactivityTimer);DRX下行重传定时器(drx-RetransmissionTimerDL);DRX上行重传定时器(drx-RetransmissionTimerUL);DRX短周期定时器(drx-ShortCycleTimer);DRX-混合自动重传-定时提前量-下行定时器(drx-HARQ-RTT-TimerDL);DRX-混合自动重传-定时提前量-上行定时器(drx-HARQ-RTT-TimerUL)。
该方式通过drx-onDurationTimer控制CSI的上报,降低了PDCCH的误检概率,对高层标准没有修改,需要物理层维护多个定时器,用物理层的实现复杂度换取高层简化。
需要说明的是,本公开实施例中提及的“DRX激活期对应的时间”并不是完全与DRX激活期对等,其可理解为与DRX激活期相关的时间,例如,“DRX激活期对应的时间”包括:与DRX激活期之间存在一个偏移量的时 间段;再例如,“DRX激活期对应的时间”包括:DRX激活期、DRX激活期的起始时间之前的一段时间、DRX激活期的结束时间之后的一段时间;在此不一一枚举。同样的,本公开实施例中提及的“DRX持续时间定时器运行对应的时间”也不是完全与DRX持续时间定时器运行时间对等,其可理解为与DRX持续时间定时器运行时间相关的时间。
综上,本公开实施例中通过DMRS检测高可靠性解决了节能PDCCH漏检使得DRX激活期中PDCCH无法检测的问题;进一步考虑当节能PDCCH检测和DMRS检测结果不一致时,后续CSI上报和SRS发送相关处理;本公开实施例利用drx-InactivityTimer,采用较为简单的方法,避免了DMRS检测虚警时,CSI上报和SRS发送所带来的资源冲突问题,并且能够使得及时上报CSI的信息。
如图2所示,本公开实施例还提供一种物理下行控制信道PDCCH的检测装置,应用于终端,包括:
第一检测模块21,用于在网络侧设备配置的PDCCH检测机会上进行解调参考信号DMRS的检测;
第二检测模块22,用于进行节能PDCCH盲检;
