本申请要求在2019年08月16日提交中国专利局、申请号为201910760901.3、申请名称为“一种节能指示方法及其装置”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。
本申请涉及无线通信技术领域,尤其涉及一种节能指示方法及其装置。
在5G NR***中,终端为了获得下行调度信息,需要在每个物理下行控制信道(Physical Downlink Control Channel,PDCCH)检测(监听)机会(PDCCH monitor occasion)对PDCCH进行检测(监听),来判断是否传输有用户调度信息。其中,一个PDCCH检测机会对应一段时间长度,比如可以是几个符号的时间长度。
大多数PDCCH检测机会中,基站没有通过PDCCH发送用户调度信息。比如,在终端配置了非连续接收(Discontinuous Reception,DRX)的情况下,一个DRX周期包括激活期间和非激活期间,DRX周期中的非激活期间是没有调度信息传输的,只有在DRX的激活期间,终端才进行PDCCH的检测。在DRX周期可以令终端进入深度睡眠,当终端处于深度睡眠时,终端的功耗低于PDCCH检测所消耗的功耗。
由于每个DRX周期是否有数据调度是动态变化的,基站无法通过高层信令指示每个DRX周期内是否有调度信息传输。

本申请实施例提出了一种节能指示方法及其装置,用以指示终端进行PDCCH检测或者不进行PDCCH检测,使得终端可以根据基站的指示对 PDCCH进行检测,以保证调度信息的接收,或者不对PDCCH进行检测,以降低终端的功耗。
下面首先对本申请实施例中的一些技术名词进行说明。
(1)本申请实施例中的“终端”,又称为用户设备(User Equipment,UE)、移动台(Mobile Station,MS)、移动终端(Mobile Terminal,MT)等,是一种向用户提供语音和/或数据连通性的设备,例如,具有无线连接功能的手持式设备、车载设备等。目前,一些终端的举例为:手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(Mobile Internet Device,MID)、可穿戴设备,虚拟现实(Virtual Reality,VR)设备、增强现实(Augmented Reality,AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
(2)本申请实施例中的“基站”,可以是RAN节点或基站。RAN是网络中将终端接入到无线网络的部分。RAN节点(或设备)为无线接入网中的节点(或设备),又可以称为基站。目前,一些RAN节点的举例为:gNB、传输接收点(Transmission Reception Point,TRP)、演进型节点B(evolved Node B,eNB)、无线网络控制器(Radio Network Controller,RNC)、节点B(Node B,NB)、基站控制器(Base Station Controller,BSC)、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(Base Band Unit,BBU),或无线保真(Wireless fidelity,Wifi)接入点(Access Point,AP)等。另外,在一种网络结构中,RAN可以包括集中单元(Centralized Unit,CU)节点和分布单元(Distributed Unit,DU)节点。
(3)本申请实施例中,将用于指示终端醒来以进行PDCCH检测的指示信息,称为唤醒指示信息。唤醒指示信息也可称为唤醒信号(WakeUp Signaling, WUS)。其中,终端醒来,是指终端从睡眠状态唤醒。
(4)本申请实施例中,将用于指示终端睡去从而不进行PDCCH检测的指示信息,称为睡眠指示信息。睡眠指示信息也可称为睡眠信号(Go-To-Sleep,GTS)。其中,终端睡去,是指终端进入睡眠状态。
应当理解,本申请实施例中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,例如能够根据本申请实施例图示或描述中给出那些以外的顺序实施。
下面结合附图对本申请实施例进行详细描述。
参见图1,为本申请实施例提供的在基站侧实现的节能指示方法的流程示意图,如图所示,该流程可包括:
S101:基站确定需要醒来的终端;
S102:基站在为所述终端配置的PDCCH检测机会中,通过PDCCH向所述终端发送唤醒指示信息,所述唤醒指示信息用于指示终端醒来。
本申请的上述实施例中,基站确定需要醒来的终端,并在为该终端配置的PDCCH检测机会中,通过PDCCH向该终端发送唤醒指示信息,以指示终端醒来,以便进行PDCCH检测,从而可以接收基站发送的调度信息,从而有效得发送唤醒和睡眠信号,提高下行控制信令的传输效率,降低基站处理的复杂度。
根据图1所示的流程,在一些实施例中,基站在为终端配置的PDCCH检测机会中,还可以发送DRX周期数的指示信息,以使终端在随后的相应数量且连续的DRX周期醒来,以便进行PDCCH检测。
上述流程中的终端可以是单独的终端(即不是所配置的终端组中的终端),所述终端也可以是配置的终端组中的终端,一个终端或多个终端可以共享相同的唤醒和睡眠信息。其中,终端组的配置信息可由基站通过高层信令发送,终端根据该终端组的配置信息可获得该终端在该终端组中的位置或顺序(即该终端是所属终端组中的第几个终端)。
可选地,在上述流程中的终端为单独的终端的情况下,基站可以采用隐式方式指示终端睡去,不进行PDCCH检测。具体地,上述流程还可包括以下步骤:若基站确定该终端需要睡去,则在为该终端配置的PDCCH检测机会中,放弃通过PDCCH向该终端发送睡眠指示信息,以使得该终端在随后的一个或多个DTX周期中进入睡眠状态,不进行PDCCH检测。
可选地,在上述流程中的终端为终端组中的一个终端的情况下,基站可以采用隐式方式指示终端组中的所有终端睡去,不进行PDCCH检测。具体地,上述流程还可包括以下步骤:若基站确定终端组中的所有终端都需要睡去,则在为该终端组配置的PDCCH检测机会中,放弃通过PDCCH向该终端组中的终端发送睡眠指示信息,以使得该终端组中的终端在随后的一个或多个DTX周期中进入睡眠状态,不进行PDCCH检测。
基站是采用显式方式指示还是采用隐式方式指示,可以通过高层信令通知给终端。
可以看出,基站采用隐式方式指示终端或终端组中的所有睡去,无需通过PDCCH发送睡眠指示信息,从而可以减少资源开销,并且终端在PDCCH检测周期未收到睡眠指示信息的情况下,可以在随后的一个或多个DTX周期中睡去,从而可以降低终端的能耗。在所述指示终端组中的终端数量不多时,大多数情况均需终端睡眠,本申请实施例可以减少发送睡眠指示信息(也称睡眠PDCCH)或唤醒指示信息(也称唤醒PDCCH)的次数,节约资源,降低基站实现复杂度。
在上述流程中的终端为终端组中的一个终端的情况下,在S101中,基站确定终端组中需要醒来的终端;在S102中,基站在为该终端组配置的PDCCH检测机会中,通过PDCCH向该终端组中需要醒来的终端发送唤醒指示信息。
可选地,对于该终端组中需要睡去的终端,基站也可以发送睡眠指示信息。具体地,上述流程还可包括以下步骤:基站确定终端组中需要睡去的终端,并在为该终端组配置的PDCCH检测机会中,通过PDCCH向该终端组中需要睡去的终端发送睡眠指示信息。
基站可以通过下行控制信息(Downlink Control Information,DCI)向终端组中的终端发送唤醒指示信息和/或睡眠指示信息,使该终端组中的终端共享该DCI。具体地,基站向终端组中的终端发送第一DCI,该第一DCI中包括第一信息域,所述第一信息域中包含多个子域,每个子域对应终端组中的一个终端或多个终端,其中,需要醒来的终端所对应的子域的取值等于唤醒指示信息的取值,需要睡去的终端所对应的子域的取值等于睡眠指示信息的取值。其中,一个子域可包括一个比特或多个比特。
例如,一个终端组中包括8个终端,基站发送的DCI中包括第一信息域,该信息域包括8个比特,每个比特对应该终端组中的一个终端,用于为相应终端发送唤醒指示信息或睡眠指示信息。其中,当一个比特的取值为0时,表示向对应终端发送唤醒指示信息,当一个比特的取值为1时,表示向对应终端发送睡眠指示信息。
可选地,基站还可以为需要醒来的终端分配资源信息,并通过PDCCH将该资源信息的指示信息发送给需要醒来的终端。
其中,所述资源信息可以是与终端节能相关的配置信息,比如可包括多输入多输出(Multi-input Multi-output,MIMO)天线数/层数、辅小区(Scell)激活/去激活指示、BWP(BandWidth Part)的激活指示,非周期信道状态信息(Channel State Information,CSI)上报的触发配置信息,探测参考信号(Sounding Reference Signal,SRS)触发配置信息、时间参考信号(Time Reference Signal,TRS)的触发配置信息等信息中的一个或多个。
为节省上述配置信息所占用的DCI比特数量,可以通过高层信令将为终端配置的资源信息的具体配置信息发送给终端,资源信息指示的可能取值通过标准预定义,这样,基站在通过PDCCH将该资源信息的指示信息发送给需要醒来的终端时,只需将该指示信息(索引)通过DCI发送给终端,以节省DCI的比特开销。
可选地,基站可以通过第一DCI将为需要醒来的终端配置的资源信息的指示信息发送给相应终端,即通过同一DCI来指示需要醒来和需要睡去的终 端,并针对需要醒来的终端为其指示资源信息。在另外的实施例中,也可以通过第二DCI将为需要醒来的终端配置的资源信息的指示信息发送给相应的终端,即通过不同的DCI进行指示,一个DCI用来指示需要醒来和需要睡去的终端,另外的DCI用来针对需要醒来的终端为其指示资源信息。
在通过第一DCI发送资源信息的指示信息的实施例中,第一DCI中除了包括第一信息域以外,还包括第二信息域。第二信息域包括多个子域且所述多个子域的数量小于或等于终端组中需要醒来的终端的数量,第二信息域中的每个子域对应终端组中的一个需要醒来的终端,其中,每个子域用于携带为相应需要醒来的终端配置的资源信息的指示信息。
举例来说,一个终端组中有8个终端,该8个终端中的第一个终端(UE1)、第二个终端(UE2)、第三个终端(UE3)、第六个终端(UE6)需要被唤醒,其余终端需要睡去,则基站发送DCI,该DCI可被该终端组中的终端所共享,该DCI中包含的与本申请相关的信息以及结构可如图2所示。
如图2所示,该DCI中包括第一信息域(也称唤醒睡去指示域)和第二信息域(也称配置信息指示域)。第一信息域(唤醒睡去指示域)中包括8个比特,每个比特对应该终端组中的一个终端,用于指示相应终端是醒来还是睡去。在该例子中,当比特值取值为0,表示相应终端需要醒来,当比特值取值为1,表示相应终端需要睡去。在本例子中,由于比特1对应于该终端组中的UE1,比特2对应于该终端组中的UE2,比特3对应于该终端组中的UE3,比特6对应于该终端组中的UE6,因此第一信息域中的8个比特的取值如图2所示,表示向UE1、UE2、UE3、UE6发送的是唤醒指示信息,向其余UE发送的是睡眠指示信息。
由于该终端组中有4个终端需要醒来,因此在该DCI中的第二信息域(配置信息指示域)中包括4个子域,分别向该4个终端(UE1、UE2、UE3、UE6)指示配置信息,即每个子域承载相应终端的资源信息的指示信息。每个子域可包含M个比特(M为大于或等于1的整数)。
在终端侧,该终端组中的终端可以根据自己在该终端组中的位置,获取 该DCI中第一信息域中相应比特的取值,根据该取值确定自己是醒来还是睡去,即确定自己在随后的一个或多个DRX周期中是否检测PDCCH。如果终端确定自己需要醒来,则根据该终端在所有需要醒来的终端中的位置,确定第二信息域中该终端对应的子域,并读取该子域承载的指示信息,从而获得基站为该终端配置的资源信息。比如,对于UE1,由于其为需要唤醒的终端中的第一个终端,则UE1读取第二信息域中的第一个子域,对于UE3,由于其为需要唤醒的终端中的第三个终端,则UE3读取第二信息域中的第三个子域。
可选地,对于一个终端组中需要醒来的终端,为了使得该终端能够确定自己是该组终端中需要醒来的终端中的第几个终端,以便确定第二信息域中该终端所对应的子域的位置,基站可将该终端是该组终端中需要醒来的终端中的第几个终端的指示信息发送给该终端,或者将该终端之前有几个需要醒来的终端的指示信息发送给该终端。
可选地,在需要醒来的终端数量较多的情况下,DCI中的第二信息域可能无法承载这些需要醒来的所有终端的资源信息的指示信息。针对这种情况,本申请实施例中,可以在该DCI中的第二信息域中承载该终端组中需要醒来的所有终端中的部分终端的资源信息的指示信息,其余部分需要醒来的终端的资源信息的指示信息,可以通过其它DCI进行指示。所述其它DCI可以是用户特定的,也可以是基于终端组的(即可以被终端组中的多个终端所共享的)。
当然,在DCI的第一信息域中,一个子域也可以对应多个终端,使得该多个终端可以共享该子域所承载的唤醒指示信息或睡眠指示信息。
进一步地,如果基站发送第一DCI和第二DCI,则第一DCI和第二DCI可使用不同的聚合度(aggregation level)进行传输。其中,由于第一DCI用于发送唤醒指示信息和/或睡眠指示信息,而唤醒指示信息和睡眠指示信息对可靠性要求较高,并且所需比特数固定,因此可以采用较大的聚合度传输。
在另外的实施例中,第一DCI中的第一信息域中的每个子域,也可以对 应一个终端组,比如,第一信息域中包括8个比特,每个比特对应一个终端组,用于指示相应终端组中的终端是全部醒来还是全部睡去。通过该种方式,可以使多个终端组中的终端共享该DCI,与分别向这些终端组或终端组中的终端发送DCI相比,可以节省资源开销。
参见图3,为本申请实施例提供的终端侧实现的节能指示发送方法的流程示意图,如图所示,该流程可包括:
S301:终端在为所述终端配置的PDCCH检测机会中,通过PDCCH接收基站发送的唤醒指示信息;
S302:终端根据所述唤醒指示信息进行PDCCH检测。
可选地,在一些实施例中,基站在为终端配置的PDCCH检测机会中,还可以发送DRX周期数的指示信息。相应地,终端在为终端配置的PDCCH检测机会中接收到该指示信息后,可以根据该指示信息,在随后的相应数量且连续的DRX周期醒来,以便进行PDCCH检测。
可选地,在一些实施例中,还包括:若终端在为该终端配置的PDCCH检测机会中,未通过PDCCH接收到基站发送的唤醒指示信息和/或睡眠指示信息,则该终端在随后的一个或多个DTX周期放弃PDCCH检测。通过该方式,可实现隐式指示终端睡去,从而可以减少资源开销,并可以降低终端的能耗。
可选地,在一些实施例中,终端在为该终端配置的PDCCH检测机会中,还可通过PDCCH接收基站发送的睡眠指示信息。终端根据该睡眠指示信息,在随后的一个或多个DTX周期放弃PDCCH检测。通过该方式,可以实现显式方式指示终端睡去。
可选地,若该终端为终端组中的一个终端,则该终端通过PDCCH接收基站发送的唤醒指示信息的过程可包括:终端根据其在所属终端组中的位置,获取基站通过PDCCH发送的第一DCI的第一信息域中相应子域携带的唤醒指示信息。通过该方式,可以实现一个终端组中的终端共享一个DCI来获取唤醒指示信息或睡眠指示信息。
可选地,该终端还可以在为该终端配置的PDCCH检测机会中,通过 PDCCH接收所述基站发送的为所述终端配置的资源信息的指示信息,并根据所述资源信息的指示信息进行配置。
本申请还提供了一些实施例,可以使用PDCCH区域发送的解调参考信号(Demodulation Reference Signal,DMRS)序列来隐式指示终端组中的终端是醒来还是睡去。具体地,可以预先指定一个DMRS序列对应于唤醒指示,另一个DMRS序列对应于睡眠指示。针对一个终端组,如果该终端组中的所有终端均需要醒来,则可以使用与唤醒指示对应的DMRS序列进行DMRS传输,使得该终端组中的终端检测到该DMRS序列后可执行唤醒处理(即在随后的一个或多个DRX周期中进行PDCCH检测)。可选地,如果该终端组中的所有终端均需要睡去,则可以使用与睡眠指示对应的DMRS序列进行DMRS传输,使得该终端组中的终端检测到该DMRS序列后可执行睡眠处理(即在随后的一个或多个DRX周期中不进行PDCCH检测)。
本申请还提供了一些实施例,可以根据PDCCH序列来识别是否是睡眠指示。如果传输唤醒指示信息和/或睡眠指示信息的PDCCH加扰的PS-RNTI对应不同的终端,该加扰值是不同的,即,如果通过PDCCH指示终端组中的所有终端均睡去,则该PDCCH编码构成的序列与其它情况下的PDCCH编码序列不同(所述其它情况是指该终端组中有至少一个终端需要醒来的情况),为方便描述,这里称为睡眠PDCCH序列。因此,若该终端组中的终端检测到PDCCH序列为睡眠PDCCH序列,则可确定基站指示其睡去,该终端无需再对该睡眠PDCCH序列进行译码。采用这种方法,可以降低检测复杂度,快速识别睡眠指示,当大多数情况终端需要睡眠,本实施例可减少终端的处理开销。
本申请还提供了一些实施例,可以在用于发送唤醒指示信息和/或睡眠指示信息的DCI中,进行多终端联合指示,以节省DCI开销,或者使DCI能够承载更多的指示信息。具体地,在DCI中包含DRX周期数指示信息的情况下,可以将不同终端需要醒来或睡去的DRX周期数的各种组合情况分别进行联合编码,这样通过一个编码值或称索引值(该编码值指示某种组合情况下各终 端需要醒来或睡去的DRX周期数)即可指示多个终端醒来或睡去的DRX周期数,而不必针对每个终端指示其醒来或睡去的DRX周期数。其中,每种组合情况下各终端醒来或睡去的DRX周期数,可以由基站通过高层信令配置给终端。
通过以上描述可以看出,本申请提出了唤醒指示和睡眠指示的方法,通过对唤醒指示信息和/或睡眠指示信息以及其它节能功能相关的配置信息的联合设计,可以使得这些信息在多用户间共享,提高DCI的利用率,进一步提高资源利用率,降低用户检测功耗。本申请实施例提供的指示方法可以采用显式或隐式方式来指示终端醒来或睡去,使得***可以根据实际需要配置显式或隐式指示,提高DCI的利用率以及检测精度。
