下面详细描述本公开的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的要素。下面通过参考附图描述的实施例是示例性的,旨在用于解释本公开,而不能理解为对本公开的限制。
如图1所示,本公开实施例提供的一种传输配置信息的方法可应用于无线通信系统100,该无线通信系统可以包括用户设备101和网络设备102。其中,用户设备101被配置为支持载波聚合,并可连接至网络设备102的多个载波单元,包括一个主载波单元以及一个或 多个辅载波单元。
应理解,以上无线通信系统100既可适用于低频场景,也可适用于高频场景。无线通信系统100的应用场景包括但不限于长期演进(long term evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)系统、全球互联微波接入(worldwide interoperability for micro wave access,WiMAX)通信系统、云无线接入网络(cloud radio access network,CRAN)系统、未来的第五代(5th-Generation,5G)系统、新无线(new radio,NR)通信系统或未来的演进的公共陆地移动网络(public land mobile network,PLMN)系统等。
以上所示用户设备101可以是终端(terminal)、接入终端、终端单元、终端站、移动台(mobile station,MS)、远方站、远程终端、移动终端(mobile terminal)、无线通信设备、终端代理或终端设备等。该用户设备101可具备无线收发功能,其能够与一个或多个通信系统的一个或多个网络设备进行通信(如无线通信),并接受网络设备提供的网络服务,这里的网络设备包括但不限于图示网络设备102。
其中,用户设备(user equipment,UE)101可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字处理personal digital assistant,PDA)设备、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PLMN网络中的终端设备等。
网络设备102可以是接入网设备(或称接入网站点)。其中,接入网设备是指有提供网络接入功能的设备,如无线接入网(radio access network,RAN)基站等等。网络设备102具体可包括基站(base station,BS),或包括基站以及用于控制基站的无线资源管理设备等。该网络设备102还可包括中继站(中继设备)、接入点以及未来5G网络中的基站、未来演进的PLMN网络中的基站或者NR基站等。网络设备102可以是可穿戴设备或车载设备。网络设备102也可以是具有通信模块的通信芯片。
比如,网络设备102包括但不限于:5G中的下一代基站(gnodeB,gNB)、LTE系统中的演进型节点B(evolved node B,eNB)、无线网络控制器(radio network controller,RNC)、WCDMA系统中的节点B(node B,NB)、CRAN系统下的无线控制器、基站控制器(basestation controller,BSC)、GSM系统或CDMA系统中的基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved nodeB,或home node B,HNB)、基带单元(baseband unit,BBU)、传输点(transmitting and receiving point,TRP)、发射点(transmitting point,TP)或移动交换中心等。
结合图2所示,网络设备102可配置长周期(Long Cycle)的C-DRX,该长周期的C-DRX中,工作时段的周期较长。在长周期内嵌套短周期(Short Cycle)的场景下,工作时段的周期还包括在长周期内出现的多个短周期,工作时段出现的更加频繁。在每个工作时 段,用户设备101均需进行监听,若在工作时段内下行数据已传输完毕或者没有需要传输的下行数据,用户设备101保持监听状态会浪费自身能耗。
本公开实施例提供一种传输配置信息的方法,参照图3,图3是根据一示例性实施例示出的一种传输配置信息的方法,如图3所示,该方法包括步骤S301~S302,具体的:
步骤S301,网络设备102向用户设备101发送配置信息,配置信息用于配置在连接态下的不连续接收C-DRX的工作时段内运行的第一定时器,其中,第一定时器用于指示用户设备的主接收机在工作时段内不监听PDCCH的时机。
步骤S302,用户设备101接收配置信息。
在一些可能的实施方式中,C-DRX的工作时段对应的定时器为drx-onDurationTimer。在每次达到工作时段时,该定时器将启动,该定时器结束运行时,表明工作时段结束。
在一些可能的实施方式中,网络设备102还可配置第一定时器的启动时机以及运行时长T。
在一示例中,在工作时段内,用户设备101每收到下行控制信息(Downlink Control Information,DCI)后启动第一定时器,在运行时长T后结束运行。
在一示例中,当超过该运行时长T,即第一定时器超时,则认为此时无待接收的用于调度数据的DCI。
在一示例中,上述示例中DCI为调度新传数据的DCI。
其中,DCI中新数据标识(New Data Indicator,NDI)信息域用于指示DCI调度的数据是新传数据还是重传数据。例如,NDI信息域占用1个比特。对于相同HARQ进程标识的相邻两个DCI,若该两个DCI的NDI比特值相同,则表明后一个DCI调度的是重传数据;若该两个DCI的NDI比特值发生翻转(如前一个DCI的NDI比特值为0,后一个DCI的NDI比特值为1),表明后一个DCI调度的数据为新传数据。
在一些可能的实施方式中,当该第一定时器超时时,用户设备101可不监听PDCCH。
在一些可能的实施方式中,在工作时段内若已启动过第一定时器,且当前已无处于运行状态的第一定时器,用户设备101可不监听PDCCH。
在一些可能的实施方式中,用户设备101不监听PDCCH的状态可以认为是一种睡眠状态,在该睡眠状态下不监听PDCCH,但对于某些特殊的信道可以监听,例如,UE可以继续接收在进入该睡眠状态之前就已经被调度但还未被传输的物理下行共享信道(Physical Downlink Shared channel,PDSCH)。
在一示例中,不监听PDCCH可以是不监听设定类型的PDCCH。
在一示例中,该设定类型的PDCCH为用于数据调度的PDCCH。
在一示例中,该设定类型的PDCCH为特定类型搜索空间中的PDCCH。
例如,不监听用户特定搜索空间(UE-Specific Seach Space,USS)中的PDCCH,或者,不监听Type 3公共搜索空间(Common Searching Space,CSS)中的PDCCH。
在一些可能的实施方式中,在工作时段不监听PDCCH期间,用户设备101可通过低功耗接收机监听和接收低功耗唤醒信号(Low Power Wake Up Signal,LP WUS)。在监听到LP WUS时,唤醒并监听PDCCH。
本公开实施例中,用户设备101根据网络设备102下发的配置信息,获知可在C-DRX工作时段运行的第一定时器,从而用户设备101可以根据该第一定时器的运行情况,在工作时段内的合适时机不监听PDCCH,减少不必要的上行接收,有利于实现节能。
本公开实施例提供一种接收配置信息的方法,该方法被用户设备101执行。参照图4,图4是根据一示例性实施例示出的一种接收配置信息的方法,如图4所示,该方法包括步骤S401,具体的:
步骤S401,用户设备101接收网络设备102发送的配置信息,配置信息用于配置在连接态下的不连续接收C-DRX的工作时段内运行的第一定时器,其中,第一定时器用于指示用户设备的主接收机在工作时段内不监听PDCCH的时机。
在一些可能的实施方式中,用户设备101处于RRC连接态(Radio Resource Control Connected,RRC Connected)。
在一些可能的实施方式中,根据定时器drx-onDurationTimer确定是否在C-DRX的工作时段。
在一些可能的实施方式中,第一定时器在工作时段内运行。网络设备102可配置第一定时器的启动时机以及运行时长T。
在一示例中,用户设备101不监听PDCCH可以是不监听设定类型的PDCCH。
在一示例中,该设定类型的PDCCH为用于数据调度的PDCCH。
在一示例中,该设定类型的PDCCH为特定类型搜索空间中的PDCCH。
例如,不监听用户特定搜索空间USS中的PDCCH,或者,不监听Type 3 CSS中的PDCCH。
在一些可能的实施方式中,用户设备101不监听PDCCH的状态可以认为是一种睡眠状态,在该睡眠状态下不监听PDCCH,但对于某些特殊的信道可以监听,例如,UE可以继续接收在进入该睡眠状态之前就已经被调度但还未被传输的PDSCH。该睡眠状态可以包括:深度睡眠(Deep sleep)状态、轻睡眠(Light sleep)状态和浅睡眠(Micro sleep)状态。
本公开实施例中,用户设备101根据网络设备102下发的配置信息,获知可在C-DRX工作时段运行的第一定时器,从而用户设备101可以根据该第一定时器的运行情况,在工作时段内的合适时机不监听PDCCH,有利于实现节能。
本公开实施例提供一种接收配置信息的方法,该方法被用户设备101执行。参照图5,图5是根据一示例性实施例示出的一种接收配置信息的方法,如图5所示,该方法包括步骤S501~502,具体的:
步骤S501,用户设备101接收网络设备102发送的配置信息,配置信息用于配置在连接态下的不连续接收C-DRX的工作时段内运行的第一定时器,其中,第一定时器用于指示用户设备的主接收机在工作时段内不监听PDCCH的时机。
步骤S502,在工作时段内且在第一定时器超时后,主接收机不监听PDCCH。
在一些可能的实施方式中,第一定时器在工作时段内运行。网络设备102可配置第一定时器的启动时机以及运行时长T。
在一些可能的实施方式中,在工作时段内,用户设备101每收到DCI后启动第一定时器,在运行时长T后结束运行。
在一些可能的实施方式中,在第一定时器超时时,认为此时无待接收的用于调度数据的DCI,主接收机可以不监听PDCCH。
在一些可能的实施方式中,用户设备101包括主接收机和低功耗接收机。
其中,主接收机不监听PDCCH期间,可开启低功耗接收机。该低功耗接收机功率较小,仍可以保证用户设备101的节能。低功耗收发机用于监听和接收LP WUS,在未接收到LP WUS之前,主接收机保持不监听PDCCH以实现节能;在接收到LP WUS后,可唤醒主接收机进行数据收发等操作。
本公开实施例中,用户设备101根据第一定时器的运行情况,在工作时段内且第一定时器超时时,表明无待传输的DCI或者DCI已传输完,因此主接收机可以不监听PDCCH,从而减少工作时段不必要的上行接收,节约能耗。
本公开实施例提供一种接收配置信息的方法,该方法被用户设备101执行。参照图6,图6是根据一示例性实施例示出的一种接收配置信息的方法,如图6所示,该方法包括步骤S601~602,具体的:
步骤S601,用户设备101接收网络设备102发送的配置信息,配置信息用于配置在连接态下的不连续接收C-DRX的工作时段内运行的第一定时器,其中,第一定时器用于指示用户设备的主接收机在工作时段内不监听PDCCH的时机。
步骤S602,在工作时段内,若没有处于运行状态的第一定时器,主接收机不监听PDCCH。
在一些可能的实施方式中,网络设备102可配置第一定时器的启动时机以及运行时长T。
在一些可能的实施方式中,在工作时段内,DCI在第一定时器的运行时长内传输。
在一示例中,用户设备101收到第N个DCI后启动第一定时器,第一定时器在运行时长T后结束运行。其中,第N+1个DCI在该运行时长内传输完毕。
在一些可能的实施方式中,在工作时段的t时刻之前,若第一定时器已运行至少一次且均未超时,表明用户设备101在每次第一定时器运行期间都接收到了对应DCI。若在t时刻已无正在运行的第一定时器,表明待接收的数据均已在t时刻之前传输完毕,因此在t之后当前主接收机可不监听PDCCH。
本公开实施例中,适用于在工作时段内已运行至少一次第一定时器的场景,在没有处于运行状态的第一定时器时,用户设备101可不监听PDCCH,从而减少工作时段不必要的上行接收,节约能耗。
本公开实施例提供一种接收配置信息的方法,该方法被用户设备101执行。
该方法包括步骤S401~S402,具体的:
步骤S401,用户设备101接收网络设备102发送的配置信息,配置信息用于配置在连接态下的不连续接收C-DRX的工作时段内运行的第一定时器,其中,第一定时器用于指示用户设备的主接收机在工作时段内不监听PDCCH的时机。
步骤S402,在工作时段内接收到调度新传数据的下行控制信息DCI时,启动第一定时器。
在一些可能的实施方式中,DCI中包括新数据标识(New Data Indicator,NDI)信息域,该NDI信息域用于指示DCI调度的数据是新传数据还是重传数据。
例如,NDI信息域占用1个比特。对于相同HARQ进程标识的相邻两个DCI,若该两个DCI的NDI比特值相同,则表明后一个DCI调度的是重传数据;若该两个DCI的NDI比特值发生翻转(如前一个DCI的NDI比特值为0,后一个DCI的NDI比特值为1),表明后一个DCI调度的数据为新传数据。
在一些可能的实施方式中,若在工作时段内第一定时器超时,主接收机可不监听PDCCH。
在一些可能的实施方式中,若在工作时段内的某时刻没有处于运行状态的第一定时器,主接收机可不监听PDCCH。
本公开实施例中,示意了第一定时器的启动时机,即在每接收到一个DCI时启动一次第一定时器,从而监测后续是否还存在待传数据,以便及时接收数据或者不监听PDCCH实现节能。
本公开实施例提供一种接收配置信息的方法,该方法被用户设备101执行。
该方法包括步骤S501~503,具体的:
步骤S501,用户设备101接收网络设备102发送的配置信息,配置信息用于配置在连接态下的不连续接收C-DRX的工作时段内运行的第一定时器,其中,第一定时器用于指示用户设备的主接收机在工作时段内不监听PDCCH的时机。
步骤S502,在工作时段内且在第一定时器超时后,主接收机不监听PDCCH。
步骤S503,在工作时段内且当主接收机不监听PDCCH,通过低功耗接收机监听低功耗唤醒信号LP WUS。
或者,该方法包括步骤S601~603,具体的:
步骤S601,用户设备101接收网络设备102发送的配置信息,配置信息用于配置在连接态下的不连续接收C-DRX的工作时段内运行的第一定时器,其中,第一定时器用于指示用户设备的主接收机在工作时段内不监听PDCCH的时机。
步骤S602,在工作时段内,若没有处于运行状态的第一定时器,主接收机不监听PDCCH。
步骤S603,在工作时段内且当主接收机不监听PDCCH,通过低功耗接收机监听低功耗唤醒信号LP WUS。
在一些可能的实施方式中,低功耗接收机开始监听LP WUS的时机,可与主接收机不监听PDCCH的时机相同。
在一示例中:
如图7所示,用户设备101在t1时刻接收到第N个DCI,则在t1时刻启动第一定时器。其中,第一定时器的运行时长为T1。
若在第一定时器超时,即在t1时刻开始的T1时长后的t2时刻处仍未收到第N+1个DCI,则在t2时刻后,用户设备101的主接收机可不监听PDCCH,并启动低功耗接收机监听LP WUS。
若在第一定时器的运行时长T1内,即在t1时刻~t2时刻之间接收到第N+1个DCI,则重启第一定时器,并且用户设备101会继续监听PDCCH。参考此方式,每收到一个DCI都会重启一次第一定时器,第一定时器可能多次启动。当在t3时刻处已无处于运行状态的第一定时器,则可在t3时刻后,主接收机不监听PDCCH,并启动低功耗接收机监听LP WUS。
其中,本示例中涉及的DCI,如第N个DCI和第N+1个DCI,均为调度新传数据的DCI。
本公开实施例提供一种接收配置信息的方法,该方法被用户设备101执行。
该方法包括步骤S501~504,具体的:
步骤S501,用户设备101接收网络设备102发送的配置信息,配置信息用于配置在连接态下的不连续接收C-DRX的工作时段内运行的第一定时器,其中,第一定时器用于指示用户设备的主接收机在工作时段内不监听PDCCH的时机。
步骤S502,在工作时段内且在第一定时器超时后,主接收机不监听PDCCH。
步骤S503,在工作时段内且当主接收机不监听PDCCH,通过低功耗接收机监听低功耗唤醒信号LP WUS。
步骤S504,在工作时段内且接收到LP WUS时,主接收机由不监听PDCCH转换为监听PDCCH状态,监听下行信息。
或者,该方法包括步骤S601~604,具体的:
步骤S601,用户设备101接收网络设备102发送的配置信息,配置信息用于配置在连接态下的不连续接收C-DRX的工作时段内运行的第一定时器,其中,第一定时器用于指示用户设备的主接收机在工作时段内不监听PDCCH的时机。
步骤S602,在工作时段内,若没有处于运行状态的第一定时器,主接收机不监听PDCCH。
步骤S603,在工作时段内且当主接收机不监听PDCCH,通过低功耗接收机监听低功耗唤醒信号LP WUS。
步骤S604,在工作时段内且接收到LP WUS时,主接收机由不监听PDCCH转换至为监听PDCCH状态,监听下行信息。
在一些可能的实施方式中,主接收机转换为监听PDCCH状态,即可以正常监听PDCCH以及其他下行信息。
在一些可能的实施方式中,网络设备102在存在下行数据调度需求时,才会发送LP WUS。
在一些可能的实施方式中,在发送LP WUS之前,网络设备102可发送LP WUS的配置信息,以便用户设备101的低功耗接收机可以在合适的时频位置接收LP WUS。
在一个示例中,仍结合图7的示例,若低功耗接收机在t4时刻监听到LP WUS,则可以唤醒主接收机。主接收机可在t4时刻的唤醒时延T2之后的t5时刻唤醒,监听PDCCH以及其他下行信息。
其中,主接收机不监听PDCCH时可认为是一种睡眠状态,该睡眠状态下不监听PDCCH但对于某些特殊的信道可以监听,例如,UE可以继续接收在进入该睡眠状态之前就已经被调度但还未被传输的PDSCH。根据主接收机所处睡眠程度不同,唤醒时延T2会有所不同。例如,深度睡眠状态的唤醒时延大于轻睡眠状态的唤醒时延。
本公开实施例中,在工作时段不监听PDCCH的场景下,用户设备101通过监听LP WUS进行唤醒,从而既可以保证节能效果,又可以及时监听PDCCH。
本公开实施例提供一种接收配置信息的方法,该方法被用户设备101执行。
该方法包括步骤S501~504’,具体的:
步骤S501,用户设备101接收网络设备102发送的配置信息,配置信息用于配置在连接态下的不连续接收C-DRX的工作时段内运行的第一定时器,其中,第一定时器用于指示用户设备的主接收机在工作时段内不监听PDCCH的时机。
步骤S502,在工作时段内且在第一定时器超时后,主接收机不监听PDCCH。
步骤S503,在工作时段内且当主接收机不监听PDCCH,通过低功耗接收机监听低功耗唤醒信号LP WUS。
步骤S504’,在工作时段结束且未接收到LP WUS时,停止监听LP WUS。
或者,该方法包括步骤S601~604’,具体的:
步骤S601,用户设备101接收网络设备102发送的配置信息,配置信息用于配置在连接态下的不连续接收C-DRX的工作时段内运行的第一定时器,其中,第一定时器用于指示用户设备的主接收机在工作时段内不监听PDCCH的时机。

步骤S604’,在工作时段结束且未接收到LP WUS时,停止监听LP WUS。
在一些可能的实施方式中,当drx-onDurationTimer超时,表明工作时段结束。在工作时段结束后,用户设备101将进入休眠时段(off-duration)。
在一些可能的实施方式中,若用户设备101进入休眠时段,即表明将处于节能状态不监听PDCCH,因此此时若还未监听到LP WUS,可停止监听LP WUS。
本公开实施例中,当工作时段结束,用户设备101可停止监听LP WUS。
本公开实施例提供一种接收配置信息的方法,该方法被用户设备101执行。参该方法包括步骤S401,具体的:

例如,根据C-DRX配置应用的载波,将多个相同载波的C-DRX配置划分为一个C-DRX组。
另一种实施例,一个C-DRX组包括应用了同一个C-DRX配置的一个或者多个载波。例如,对于用户设备的多个服务载波,可将多个服务载波划分为不同的C-DRX组,每个C-DRX组内的载波应用同一个C-DRX配置。
