背景技术
5G新空口(new radio,NR)系统中,系统带宽可以划分为多个分量载波(carrier component,CC),网络设备在每个CC上分别传输所述每个CC对应的组公共(group common)物理下行控制信道(physical downlink control channel,PDCCH)给用户设备(user equipment,UE)。group common PDCCH用于指示UE组(group)中包括的UE的公共(common)信息,即组UE公共信息(group UE common information),其中基站下的所有UE可以构成一个UE group,或者基站下的所有UE可以分为多个UE group。
现有中,UE为了获取common信息,需要从每个CC中检测group common PDCCH来获取为该UE配置的CC中的group UE common information,从而导致检测group common PDCCH的次数较多,功耗比较大。
发明内容

需要说明的是,在N等于M时,在M个CC的每个CC上传输的组公共PDCCH中均承载相同的组UE公共信息,即指示所述终端设备在N个分量载波CC上的任意一个CC上检测至少一个组公共PDCCH,从而终端设备可以选择任意一个CC上检测组公共PDCCH,并从组公共PDCCH上接收组UE公共信息即可。
在一种可能的设计中,所述N个CC是为所述终端设备配置的M个CC中的N个。基于此,终端设备可以从配置的M个CC中N个来检测组公共PDCCH,从而避免所述终端设备检测不是配置给自身的CC,增加功耗。
在一种可能的设计中,所述第一信息中包括所述N个CC的索引值。上述设计中,网络设备指示用于检测至少一个组公共PDCCH的N个CC的索引值,从而终端设备仅根据索引值即确定在哪个CC上检测至少一个组公共PDCCH,提供了简单有效的方式。
在一种可能的设计中,所述组公共PDCCH用于指示为所述终端设备配置的M个CC的组用户设备UE公共信息。所述组UE公共信息可以包括:时域单元格式信息、组UE的频域资源信息、优先占用指示信息中的至少一种。
上述设计,网络设备通过组公共PDCCH来指示为所述终端设备配置的M个CC的组UE公共信息,从而终端设备确定后续传输数据所采用的时频域资源。

在一种可能的设计中,所述终端设备在接收网络设备发送的第一信息时,具体可以通过如下方式实现:所述终端设备接收所述网络设备发送的下行控制信息DCI信令,所述DCI信令携带所述第一信息;或者,所述终端设备接收所述网络设备发送的无线资源控制RRC信令,所述RRC信令携带所述第一信息;或者,所述终端设备接收所述网络设备发送的小区广播信令,所述RRC信令携带所述第一信息。

需要说明的是,在N等于M时,在M个CC的每个CC上传输的组公共PDCCH中均承载相同的组UE公共信息,即可以配置所述终端设备在N个分量载波CC上的任意一个CC上检测至少一个组公共PDCCH,从而终端设备可以选择任意一个CC上检测组公共PDCCH,并从组公共PDCCH上接收组UE公共信息即可。
在一种可能的设计中,所述N个CC是为所述终端设备配置的M个CC中的N个。
在一种可能的设计中,网络设备与终端设备可以采用静态配置方式,确定在哪个CC上向哪个终端设备发送用于承载组UE公共信息的组公共PDCCH。

具体实施方式
本申请实施例可以应用于但不限于能够传输上行控制信令的通信系统中,比如新空口(英文:new radio,简称:NR)系统,可以用于NR系统的架构如图1所示:NR系统中包括基站和终端设备,基站与终端设备之间进行上行传输以及下行传输。
本申请实施例可以应用于载波聚合(carrier aggregation,CA)或者双连接(dual-connectivity,DC)场景中。
以下为了后续描述方便,先对本申请中的部分用语进行解释说明,以便与本领域技术人员理解。
组公共PDCCH(group common PDCCH),是针对一组UE来说的,用于指示一组UE的公共信息,即组UE公共信息(group UE common information)。
组公共PDCCH包括多个域,每个域占用一定比特数量的信息位,不同的域用于承载不同的信息。
组UE公共信息(group UE common information),基站下的所有UE可以构成一个UE组(UE group),或者基站下的所有UE可以分为多个UE group,group UE common information包括UE组中所有UE对应的公共信息。该组UE也可以理解为一个小区中的所有UE,或者一个小区下所有UE按照某种规则(例如,按照业务区分)划分的UE组,或者多个小区内的UE组成的一个组。
所述组UE公共信息包括:例如,时域单元格式信息、组UE的频域资源信息、优先占用指示信息(preemption indication)中的任意一种,组UE公共信息可能还包括其他组UE的公共信息,本申请中不作限定。其中,时域单元可以为时隙、或者子帧、帧、迷你时隙(mini-slot,或non-slot)或者K个正交频分复用(orthogonal frequency division multiplexing,OFDM)符号等等中的任一种,K为大于等于1的整数。
比如针对时隙格式信息(slot format related information,SFI)来说,5G NR系统中,可以支持多种时隙(slot)的结构,一个时隙中可以包括一个部分也可以包括多个部分,比如仅包括上行(uplink,UL)传输的时隙、或者仅包括下行(downlink,UL)传输的时隙,或者包括UL传输以及DL传输的时隙,该时隙还包括保护间隔(guard interval,GP),该保护间隔用于收发双发进行上下行转换,或者包括时隙中还可能包含未知(unknown)或者灵活(flexible)资源,即UE并不知道这部分资源是用于UL传输还是DL传输的,或者该资源可以灵活的被指成UL传输或者DL传输的资源等等。其中,UL传输可以包括UL数据传输和/UL控制传输,DL传输可以包括DL数据传输和/DL控制传输。参见图2所示的类型1至类型7分别对应的一个时隙。因此,一个slot中包括的几个部分,这几个部分所占的符号长度均需要基站指示给终端设备。
本申请实施例中网络设备可以是基站,或者是能够实现基站的功能的设备。本申请实 施例中以基站为例进行说明,基站(例如,接入点)可以指接入网中在空中接口上通过至少一个扇区与终端设备通信的设备。基站还可协调对空中接口的属性管理。例如,基站可以是LTE中的演进型基站或NR系统中的基站(gNB)或接入点,本申请实施例中并不限定。需要说明的是,本申请实施例中所述的基站不仅可以是基站设备,还可以是中继设备,或者具备基站功能的其他网元设备。
终端设备可以是无线终端也可以是有线终端,无线终端可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(英文:radio access network,简称:RAN)与至少一个核心网进行通信,无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(英文:personal communication service,简称:PCS)电话、无绳电话、会话发起协议(英文:session initiation protocol,简称:SIP)话机、无线本地环路(英文:wireless local loop,简称:WLL)站、个人数字助理(英文:personal digital assistant;简称:PDA)等设备。无线终端也可以称为系统、订户单元(英文:subscriber unit,简称:SU)、订户站(英文:subscriber station,简称:SS),移动站(英文:mobile station,简称:MB)、移动台(mobile)、远程站(英文:remote station,简称:RS)、接入点(英文:access point,简称:AP)、远程终端(英文:remote terminal,简称:RT)、接入终端(英文:access terminal,简称:AT)、用户终端(英文:user terminal,简称:UT)、用户代理(英文:user agent,简称:UA)、终端设备(英文:user device,简称:UD)、或用户装备(英文:user equipment,简称:UE)。后续将终端设备称为UE。
另外,需要理解的是,在本申请的描述中,“第一”、“第二”等词汇,仅用于区分描述的目的,而不能理解为指示或暗示相对重要性,也不能理解为指示或暗示顺序。本申请描述中的多个是指两个或者两个以上。
本申请实施例提供一种信息传输方法及装置,用以解决现有终端设备检测group common PDCCH的次数较多,功耗比较大的问题。其中,方法和装置是基于同一发明构思的,由于方法及装置解决问题的原理相似,因此装置与方法的实施可以相互参见,重复之处不再赘述。
参见图3所示,为本申请实施例提供的一种信息传输方法流程示意图。该信息传输方法包括:
S301,网络设备生成第一信息。
S302,所述网络设备向终端设备发送所述第一信息,所述第一信息用于指示所述终端设备在N个分量载波CC上检测至少一个组公共PDCCH,所述N为正整数,且小于或等于M,所述M等于为所述终端设备配置的CC的数量。
所述第一信息中可以包括所述至少一个组公共PDCCH所占用的所述N个CC的索引值。
S303,所述终端设备接收所述网络设备发送的第一信息,所述第一信息用于指示所述终端设备在N个分量载波CC上检测至少一个组公共PDCCH,所述N为正整数,且小于或者等于M,所述M等于为所述终端设备配置的CC的数量。
S304,所述终端设备根据所述第一信息在所述N个CC上检测所述至少一个组公共PDCCH。
通过上述方案,网络设备在终端设备检测组公共PDCCH之前,向该终端设备发送用于指示终端设备在哪个CC上检测组公共PDCCH,终端设备不需要检测所有的CC来获取组公共PDCCH,减少了终端设备盲检测的次数,降低了终端设备的功耗。
可选地,所述N个CC可以是为所述终端设备配置的M个CC中的N个,即网络设备可以配置在为所述终端设备配置的M个CC中的N个中承载至少一个组公共物理下行控制信道PDCCH,并将配置指示给终端设备,从而减少终端设备盲检测的次数,降低功耗。
可选地,所述组公共PDCCH用于指示为所述终端设备配置的M个CC的组UE公共信息,从而在步骤S304所述终端设备根据所述第一信息在所述N个CC上检测所述至少一个组公共PDCCH之后,还可以包括:
S305,所述终端设备从检测到的所述至少一个组公共PDCCH中接收为所述终端设备配置的M个CC的组UE公共信息。
需要说明的是,当N等于M时,在M个CC的每个CC上的组公共PDCCH中均承载相同的组UE公共信息,从而终端设备可以选择任意一个CC上检测组公共PDCCH,并从组公共PDCCH上接收组UE公共信息即可。
基于此,所述终端设备获取到组UE公共信息后,能够基于组UE公共信息确定传输或者接收数据所采用的时频域资源,或时隙格式,或者优先占用指示等信息。
可选地,所述网络设备在向终端设备发送所述第一信息时,具体可以通过如下方式实现:
所述网络设备通过下行控制信息(downlink control information,DCI)信令或者无线资源控制(radio resource control,RRC)信令或者小区广播信令,向所述终端设备发送所述第一信息。从而,所述终端设备接收所述网络设备发送的第一信息时,具体可以通过如下方式实现:所述终端设备接收所述网络设备发送的DCI信令,所述DCI信令携带所述第一信息;或者,所述终端设备接收所述网络设备发送的RRC信令,所述RRC信令携带所述第一信息;或者,所述终端设备接收所述网络设备发送的小区广播信令,所述RRC信令携带所述第一信息。
本申请实施例中所述第一信息用于指示所述终端设备在N个CC上检测至少一个组公共PDCCH时,具体可以通过如下任一方式实现:
方式一:第一信息包括为所述终端设备配置的N个CC的索引值。
方式二:第一信息包括为所述终端设备配置的M个CC的索引值与承载group common PDCCH的N个CC的索引值,以及组UE公共信息(group UE common information)中的域之间的对应关系。
方式三:第一信息包括为所述终端设备配置的M个CC的索引值与承载group common PDCCH的N个CC的索引值,组UE公共信息中的域,以及加扰组UE公共信息采用的标识信息之间的对应关系。
方式四:第一信息包括为所述终端设备配置的N个CC的索引值以及方式二和方式三中的一种对应关系,此种方式下,网络设备可以将为所述终端设备配置的N个CC的索引值以及对应关系通过同一信令发送给终端设备,网络设备也可以通过不同的信令分别将为所述终端设备配置的N个CC的索引值以及对应关系发送给终端设备。本申请实施例对此不作具体限定。
下面结合具体应用场景对本申请实施例提供的方案作具体说明。下面以网络设备是基站为例,由于终端设备组中包括的各个终端设备的group UE common information相同,因此后续以一个终端设备组为例进行说明。
本申请实施例中可以应用载波聚合场景下或者双连接场景下。
在载波聚合场景下,可以分为两种情况,第一种情况:一个基站占用的所有的CC为一个CC组,即所有的CC组成一个CC group。第二种情况:一个基站包括的所有的CC分为L个CC组,L大于2。
在DC场景下,可以分为两种情况,第一种情况:包括一个宏小区和多个小小区,该一个宏小区和多个小小区构成一个组。第二种情况:包括多个宏小区和多个小小区,该多个宏小区和多个小小区可以分为多个组。
其中,一般情况下,宏小区(Macro cell)占用一个CC、每个小小区(small cell)占用一个CC,从而宏小区(Macro cell)占用的一个CC和多个small cell占用的多个CC可以构成一个CC group。基于此,下面从CC的角度针对载波聚合场景进行具体说明,DC场景中宏小区以及小小区下的信息传输方式可以参见从CC角度描述的载波聚合场景下的信息传输方式,不再详细赘述。
针对载波聚合场景的第一种情况通过如下实施例一进行具体说明。
实施例一
一个基站占用的所有的CC为一个CC组,即所有的CC组成一个CC group。基站可以配置在CC组中其中N个CC用来承载至少一个group common PDCCH。该至少一个group common PDCCH用来承载该CC group中所有CC的组UE公共信息(group UE common information)。比如group UE common information包括SFI,UE从该N个CC中获取到SFI后,能够根据SFI确定在哪个CC上的时隙的格式。
比如基站占用的CC包括CC1~CC6,CC1为用来承载至少一个group common PDCCH的CC,则基站向所有UE组中的UE发送第一信息,第一信息用来指示UE在CC1上检测至少一个group common PDCCH,该至少一个group common PDCCH承载了该CC组中所有CC的group UE common information。从而UE接收到该第一信息后,能够根据第一信息在CC1上检测至少一个组公共PDCCH,并在至少一个组公共PDCCH中获取到为自身配置的CC的group UE common information。
基于此,基站在为UE配置CC时,需要为所有UE组均配置有CC1。
具体的,在上述方式一所述描述的情况下:第一信息可以包括用于承载至少一个group common PDCCH的CC1的索引值,从而终端设备可以通过该CC1的索引值,能够确定从CC1上检测group common PDCCH。
在上述方式二所描述的情况下:第一信息可以包括为所述终端设备配置的CC的索引值与承载group common PDCCH的CC的索引值,以及组UE公共信息中的域之间的对应关系。从而UE通过第一信息能够确定在哪个CC上检测group common PDCCH,并且能够确定承载在group common PDCCH中group UE common information的哪个域中包括哪个CC的group UE common information。比如参见表1所示。上述对应关系可以通过表格的方式通知UE,当然也可以通过表格以外的其它方式来通知UE。
在上述方式三所描述的情况下:第一信息可以包括为所述终端设备配置的CC的索引值 与承载group common PDCCH的CC的索引值,加扰group UE common information所采用的标识信息,以及group UE common information中的域之间的对应关系。
该group UE common information可以使用CC group的标识信息加扰,或者,该group UE common information可以使用被分配CC group的UE group的标识信息加扰,或者,该group UE common information可以使用被分配CC group的其中任一个UE的标识信息的标识信息加扰,或者该group UE common information可以使用网络侧配置的标识信息加扰,本申请不作具体限定。从而UE通过第一信息能够确定在哪个CC上检测group common PDCCH,通过什么标识信息进行解扰承载在group common PDCCH中的group UE common information,并且能够确定解扰后的group UE common information的哪个域中包括哪个CC的group UE common information。
表1
Figure PCTCN2018086282-appb-000001
在上述方式四所描述的情况下:第一信息中可以包括用于承载至少一个group common PDCCH的CC的索引值以及还可以包括方式二中所述的对应关系和方式三中所述的对应关系中的一种。其中,基站可以通过相同的或者不同的信令将用于承载至少一个group common PDCCH的CC的索引值以及上述方式二或者方式三中描述的对应关系发送给UE。
上述方案中,在最大程度上减少UE盲检测的次数,UE仅需要检测一个CC上的group common PDCCH来获取为该UE配置的CC的group UE common information。
但是,在上述情况下,为每个UE配置的CC中均需要包括具有group common PDCCH的CC,因此导致调度不灵活。
当然,还可以选择多个CC均用来承载group common PDCCH,每个CC上的group common PDCCH均可以承载所有CC的group UE common information。但是,在该情况下,多个CC包含group common PDCCH,虽然增加了调度的灵活性,但是group common PDCCH中的group UE common information的开销较大,并且如果UE没有被分配全部的CC,其实UE并不需要知道所有的CC的group UE common information。
在DC场景下中的第一种情况下,包括一个宏小区和多个小小区,该一个宏小区和多个小小区构成一个组。具体配置宏小区承载group common PDCCH,该group common PDCCH用于承载所有的小区的group UE common information。
针对载波聚合场景的第二种情况通过如下实施例二进行具体说明。
实施例二
一个基站占用的所有的CC分为多个CC group。基站可以配置在每个CC group中其中一个或者多个CC用来承载至少一个group common PDCCH,该至少一个group common PDCCH用来承载该CC group中所有CC的group UE common information。比如group UE common information包括SFI,UE从该CC group中1个或者多个CC中获取到SFI后,能够根据SFI确定在该CC group中哪个CC的时隙格式。
比如,一个基站下共占用20个CC,分为4个组,每个组中均包含5个CC。可以从每个组的5个CC中选择其中一个或者多个CC用来承载一个group common PDCCH。本申请实施例中以在每个组中选择一个CC来承载group common PDCCH为例,该group common PDCCH用于指示该CC组内所有CC上的group UE common information。
在上述配置下,基站可以通过第一信息将用于承载group common PDCCH的CC指示给UE。该第一信息用于指示UE在至少一个分量载波CC上检测group common PDCCH,该group common PDCCH承载了为UE配置的CC的group UE common information。
在DC场景下中的第二种情况下,包括多个宏小区和多个小小区,该多个宏小区和多个小小区构成多个组。比如4个宏小区和20小小区,则可以包括4个组,每个组中包括5个小区,分别为一个宏小区和4个小小区。在每个组中,在宏小区中承载group common PDCCH,该group common PDCCH承载该组中的所有的小区的group UE common information。从而基站向UE发送第一信息,第一信息指示UE通过宏小区检测group common PDCCH,从而UE从group common PDCCH中获取该宏小区对应的组中所有的小区的group UE common information。
具体的,本申请实施例中分为两种可能的方式针对实施例二进行具体说明。第一种可能的方式:以CC为颗粒度为UE配置CC,即为UE配置的CC中可能跨越不同的CC组,比如包括CC group1中的CC1,还包括CC group2中的CC4和CC5。第二种可能的方式:以CC组为颗粒度为UE配置CC,即为UE配置一个CC组或者多个CC组中包括的所有CC。
针对第一种可能的方式(以CC为颗粒度为UE配置CC):
以一个基站下所有的CC分为两个CC group为例,CC group1和CC group2,并且CC group1和CC group2之间包括的CC没有共有(overlap)的CC。具体的,CC group1中包括CC1~CC4,CC group2中包括CC5~CC8。
参见图4所示,假设配置给UE group1的CC包括CC group1中CC1和CC4,以及CC group2中CC5和CC7。其中,CC group1中CC1以及CC group2中的CC5均用来承载group common PDCCH,该CC1上的group common PDCCH用来承载CC1~CC4上的group UE common information,CC5上的group common PDCCH用来承载CC5~CC8上的group UE common information。
基于此配置方式,基站向UE group1中每个UE发送第一信息,下面以一个UE为例。基站向UE发送第一信息,该第一信息用于指示UE在CC1和CC5上检测group common PDCCH。在第一信息用于指示所述终端设备在CC1和CC5上检测至少一个组公共PDCCH时,可以采用上述方式一至方式四中的任意一种方式,此处以上述方式二所描述的情况为例,第一信息可以包括为所述UE配置的CC的索引值与承载group common PDCCH的CC的索引值,以及group UE common information中的域之间的对应关系。从而UE通过第一 信息能够确定在哪个CC上检测group common PDCCH,并且能够确定承载在检测到的group common PDCCH中的group UE common information的哪个域中包括哪个CC的group UE common information。比如参见表2所示。
表2
Figure PCTCN2018086282-appb-000002
UE在接收到第一信息后,基于第一信息在CC1和CC5上检测group common PDCCH,在CC1上检测到的group common PDCCH上接收group UE common information,从该group UE common information的field1获取CC1的group UE common information,在CC1上检测到的group common PDCCH上接收group UE common information,从该group UE common information的field4获取CC4的group UE common information,在CC5上检测到的group common PDCCH上接收group UE common information,从该group UE common information的field2获取CC5的group UE common information,在CC5上检测到的group common PDCCH上接收group UE common information,从该group UE common information的field3获取CC7的group UE common information。
通过上述方案,UE仅需要在基站指示的CC上检测group common PDCCH,并从group common PDCCH获取为UE配置的CC的group UE common information,从而降低了UE盲检测的次数,降低了UE的功耗。
另外,本申请实施例中,基站可以在为UE配置CC之前确定用于承载group UE common information的group common PDCCH所在的CC,从而在为UE配置CC时,仅需要保证配置给该UE的CC中包括携带该group common PDCCH的CC即可,不用每个UE必须配置某个CC,从而相比实施例一来说,能够提供为UE配置CC的灵活性。
以一个基站下所有的CC分为两个CC group为例,分别为CC group1和CC group2,并且CC group1和CC group2之间包括的CC有共有(overlap)的CC。具体的,CC group1中包括CC1~CC4,CC group2中包括CC4~CC7,CC group1和CC group2之间共有的CC为CC4。
第一种配置方式是:在共有的CC上承载group common PDCCH,第二种配置方式是:在非共有的CC上承载group common PDCCH。
针对第一种可能的方式下的第一种配置方式,在共有的CC上承载group common PDCCH进行如下说明:
参见图5所示,假设配置给UE group1的CC包括CC1、CC4以及CC6,分配给UE group2的CC包括CC2、CC4以及CC6。其中,CC4用来承载group common PDCCH,该CC4上的group common PDCCH用来承载CC1~CC7上的group UE common information。
基于此配置方式,基站分别向UE group1中每个UE发送信息1,向UE group2中每个UE发送信息2。信息1用于指示UE1在CC4上检测group common PDCCH,信息2用于指示UE2在CC4上检测group common PDCCH。下面以UE group1中的UE1为例。在信息1用于指示所述UE1在CC4上检测至少一个组公共PDCCH时,可以采用上述方式一至方式四中的任意一种方式,以上述方式二所描述的情况为例,信息1中包括为所述UE1配置的CC的索引值与承载group common PDCCH的CC的索引值,以及group UE common information中的域之间的对应关系。UE1通过第一信息能够确定在哪个CC上检测group common PDCCH,并且能够确定承载在检测到的group common PDCCH上的group UE common information的哪个域中包括哪个CC的group UE common information。比如参见表3所示。
表3

UE1在接收到信息1后,基于信息1在CC4上检测group common PDCCH,在CC4上检测到的group common PDCCH上接收group UE common information,从该group UE common information的field1获取CC1的group UE common information,在CC4上检测到的group common PDCCH上接收group UE common information,从该group UE common information的field4获取CC4的group UE common information,在CC4上检测到的group common PDCCH上接收group UE common information,从该group UE common information的field6获取CC6的group UE common information。
通过上述方案,UE仅需要在基站指示的CC上检测group common PDCCH,并从group common PDCCH获取为UE配置的CC的group UE common information,从而降低了UE盲检测的次数,降低了UE的功耗。
另外,本申请实施例中,基站可以在为UE配置CC之前确定用于承载group UE common information的group common PDCCH所在的CC,从而在为UE配置CC时,仅需要保证配置给该UE的CC中包括携带该group common PDCCH的CC即可,不用每个UE必须配置某个CC,从而相比实施例一来说,能够提供为UE配置CC的灵活性。
针对第一种可能的方式下的第二种配置方式,在非共有的CC上承载group common PDCCH进行如下说明:
参见图6所示,假设配置给UE group1的CC包括CC1、CC4,分配给UE group2的CC包括CC4以及CC5。其中,CC1和CC5用来承载group common PDCCH,该CC1上的group common PDCCH用来承载CC1~CC4上的group UE common information,该CC5上的group common PDCCH用来承载CC4~CC7上的group UE common information。
基于此配置方式,基站分别向UE group1每个UE发送信息1,信息1用于指示UE group1 中UE在CC1上检测group common PDCCH,基站向UE group2中每个UE发送信息2,信息2用于指示UE group2中的UE在CC5上检测group common PDCCH。
分别以UE group1中UE1和UE group2中UE2为例。
基站向UE1发送信息1,在信息1用于指示所述UE1在CC1上检测至少一个组公共PDCCH时,可以采用上述方式一至方式四中的任意一种方式,以上述方式二所描述的情况为例。信息1可以包括为所述UE1配置的CC的索引值与承载group common PDCCH的CC的索引值,以及group UE common information中的域之间的对应关系。从而UE1通过信息1能够确定在哪个CC上检测group common PDCCH,并且能够确定承载在检测到的group common PDCCH中的group UE common information的哪个域中包括哪个CC的group UE common information。比如参见表4所示。
表4
Figure PCTCN2018086282-appb-000004
UE1在接收到信息1后,基于信息1在CC1上检测group common PDCCH,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field1获取CC1的group UE common information,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field4获取CC4的group UE common information。
基站向UE2发送信息2,在信息2用于指示所述UE2在CC5上检测至少一个组公共PDCCH时,可以采用上述方式一至方式四中的任意一种方式,以上述方式二所描述的情况为例,信息2可以包括为所述UE2配置的CC的索引值与承载group common PDCCH的CC的索引值,以及group UE common information中的域之间的对应关系。从而UE2通过信息2能够确定在哪个CC上检测group common PDCCH,并且能够确定承载在检测到的group common PDCCH中的group UE common information的哪个域中包括哪个CC的group UE common information。比如参见表5所示。
表5
Figure PCTCN2018086282-appb-000005
UE2在接收到信息2后,基于信息2在CC5上检测group common PDCCH,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field1获取CC4的group UE common information,在检测到的group common  PDCCH上接收group UE common information,从该group UE common information的field2获取CC5的group UE common information。
通过上述方案,UE仅需要在基站指示的CC上检测group common PDCCH,并从group common PDCCH获取为UE配置的CC的group UE common information,从而降低了UE盲检测的次数,降低了UE的功耗。
另外,本申请实施例中,基站可以在为UE配置CC之前确定用于承载group UE common information的group common PDCCH所在的CC,从而在为UE配置CC时,仅需要保证配置给该UE的CC中包括承载该group common PDCCH的CC即可,不用每个UE必须配置某个CC,从而相比实施例一来说,能够提供为UE配置CC的灵活性。并且,在不同的CC group中共有的CC较多时,用于承载group common PDCCH的CC不为共有的CC时,为UE配置CC时,相比用于承载group common PDCCH的CC为共有的CC来说,能够进一步提高为UE配置CC的灵活性,使得系统的负载均衡。
下面以4个CC group为例,并且任意两个CC group之间均包括共有的CC。承载group common PDCCH的CC不为共有的CC,针对用于承载group common PDCCH的CC不为共有的CC的情况下,如何提高负载均衡具体说明。
比如,参见表6所示的第2行,分量载波a为CC group1、CC group2以及CC group3中共有的CC,参见表6所示的第3行,分量载波b为CC group2、CC group3以及CC group4中共有的CC,参见表6所示的第4行,分量载波c为CC group1、CC group2中共有的CC,参见表6所示的第5行,分量载波d为CC group3、CC group4中共有的CC。其中,CC group1中承载group common PDCCH的分量载波为CC1,CC group2中承载group common PDCCH的分量载波为CC2,CC group3中承载group common PDCCH的分量载波为CC3,CC group4中承载group common PDCCH的分量载波为CC4。基于此在为UE配置CC时,针对配置载波a,b,c或d时,可以考虑CC1,CC2,CC3和CC4上分配UE的数量,有利于系统负载均衡。比如,载波a和CC1分配给UE1,载波b和CC3分配给UE2,载波c和CC2分配给UE3,载波d和CC4分配给UE4。

a CC group1 CC group2 CC group3  
b   CC group2 CC group3 CC group4
c CC group1 CC group2

下面针对第二种可能的方式(以CC组为颗粒度为UE配置CC)进行具体说明。
以一个基站下所有的CC分为两个CC group为例,分别为CC group1和CC group2,并且CC group1和CC group2之间包括的CC没有共有(overlap)的CC。具体的,CC group1 中包括CC1~CC4,CC group2中包括CC5~CC8。
参见图7所示,假设配置给UE group1的CC为CC group1中所有CC,配置给UEgroup2的CC为CC group2中的所有CC。其中,CC group1中CC1以及CC group2中的CC5均用来承载group common PDCCH,该CC1上的group common PDCCH用来承载CC1~CC4上的group UE common information,CC5上的group common PDCCH用来承载CC5~CC8上的group UE common information。
基于此配置方式,基站分别向UE group1每个UE发送信息1,信息1用于指示UE group1中UE在CC1上检测group common PDCCH,基站向UE group2中每个UE发送信息2,信息2用于指示UE group2中的UE在CC5上检测group common PDCCH。
分别以UE group1中UE1和UE group2中UE2为例。
基站向UE1发送信息1,在信息1用于指示所述UE1在CC1上检测至少一个组公共PDCCH时,可以采用上述方式一至方式四中的任意一种方式,以上述方式二所描述的情况为例.信息1可以包括为所述UE1配置的CC的索引值与承载group common PDCCH的CC的索引值,以及group UE common information中的域之间的对应关系。从而UE1通过信息1能够确定在哪个CC上检测group common PDCCH,并且能够确定承载在检测到的group common PDCCH中的group UE common information的哪个域中包括哪个CC的group UE common information。比如参见表7所示。
表7

UE1在接收到信息1后,基于信息1在CC1上检测group common PDCCH,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field1获取CC1的group UE common information,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field2获取CC2的group UE common information,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field3获取CC3的group UE common information,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field4获取CC4的group UE common information。
基站向UE2发送信息2,在信息1用于指示所述UE2在CC5上检测至少一个组公共PDCCH时,可以采用上述方式一至方式四中的任意一种方式,以上述方式二所描述的情况为例。信息2可以包括为所述UE2配置的CC的索引值与承载group common PDCCH的CC的索引值,以及group common PDCCH包括的域之间的对应关系。从而UE2通过信息2能 够确定在哪个CC上检测group common PDCCH,并且能够确定承载在检测到的group common PDCCH中的group UE common information的哪个域中包括哪个CC的group UE common information。比如参见表8所示。
表8

UE2在接收到信息2后,基于信息2在CC5上检测group common PDCCH,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field1获取CC5的group UE common information,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field2获取CC6的group UE common information,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field3获取CC7的group UE common information,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field4获取CC8的group UE common information。
通过上述方案,UE仅需要在基站指示的CC上检测group common PDCCH,并从group common PDCCH获取为UE配置的group UE common information,从而降低了UE盲检测的次数,降低了UE的功耗。
另外,本申请实施例中,基站可以在为UE配置CC之前确定用于承载group UE common information的group common PDCCH所在的CC,从而在为UE配置CC时,仅需要保证配置给该UE的CC中包括承载该group common PDCCH的CC即可,不用每个UE必须配置某个CC,从而相比实施例一来说,能够提供为UE配置CC的灵活性。
以一个基站下所有的CC分为两个CC group为例,分别为CC group1和CC group2,并且CC group1和CC group2之间包括的CC有共有(overlap)的CC。具体的,CC group1中包括CC1~CC4,CC group2中包括CC4~CC7。CC group1配置给UE group1,CC group2配置给UE group2。
第一种配置方式是:在共有的CC上承载group common PDCCH,第二种配置方式是:在非共有的CC上承载group common PDCCH。
针对第二种可能的方式下的第一种配置方式,在共有的CC上承载group common PDCCH进行如下说明:
参见图8所示,CC group1和CC group2之间共有的CC为CC4。其中,CC4用来承载group common PDCCH,该CC4上的group common PDCCH用来承载CC group1和CC group2中的CC的group UE common information。因此,该CC4中可以承载两个group common  PDCCH,分别用于指示CC group1上的group UE common information,以及指示CC group2上的group UE common information。
基于此,两个group common PDCCH上承载的group UE common information可以分别使用CC group1以及CC group2的标识信息加扰,或者,两个group common PDCCH上承载的group UE common information可以分别使用被分配CC group1的UE group1的标识信息以及被分配CC group2的UE group2的标识信息加扰,或者,两个group common PDCCH上承载的group UE common information可以分别使用被分配CC group1的其中任一个UE的标识信息以及被分配CC group2的其中任一个UE的标识信息加扰,或者两个group common PDCCH上承载的group UE common information可以分别使用网络侧配置的标识信息加扰(需要分别告知被分配CC group1的UE group1中的UE和被分配CC group2的UE group2中的UE),用以区分该两个group common PDCCH上承载的group UE common information。
基于此配置方式,基站分别向UE group1中每个UE发送信息1,向UE group2中每个UE发送信息2。下面以UE group1中UE1和UE group2中UE2为例。基站向UE1发送信息1,该信息1用于指示UE1在CC4上检测group common PDCCH。具体的,信息1可以包括为所述UE1配置的CC的索引值与承载group common PDCCH的CC的索引值,以及group UE common information包括的域、加扰group UE common information采用的标识信息之间的对应关系。从而UE1通过信息1能够确定在哪个CC上检测group common PDCCH,通过什么标识信息进行解扰group UE common information,并且能够确定解扰后的group UE common information的哪个域中包括哪个CC的group UE common information。比如参见表9所示。
表9

基站向UE2发送信息2,该信息2用于指示UE2在CC4上检测group common PDCCH。具体的,信息2可以包括为所述UE2配置的CC的索引值与承载group common PDCCH的CC的索引值,以及group UE common information包括的域、加扰group UE common information采用的标识信息之间的对应关系。从而UE2通过信息2能够确定在哪个CC上检测group common PDCCH,通过什么标识信息进行解扰group UE common information,并且能够确定解扰后的group UE common information的哪个域中包括哪个CC的group UE common information。比如参见表10所示。
表10
Figure PCTCN2018086282-appb-000009
当然,第二种可能的方式下的第一种配置方式中,CC4上也可以只存在一个group common PDCCH,用于承载group UE common information,该group UE common information用于指示CC group1中CC的group UE common information,以及指示CC group2中CC的group UE common information。该group UE common information可以使用CC group1和CC group2共有的标识信息加扰,或者,该group UE common information可以使用被分配CC group1的UE group1和被分配CC group2的UE group2共有的标识信息加扰,或者,该group UE common information可以使用被分配CC group1的其中任一个UE的标识信息或被分配CC group2的其中任一个UE的标识信息加扰,或者该group UE common information可以使用网络侧配置的标识信息加扰(需要分别告知被分配CC group1的UE group1中的UE和被分配CC group2的UE group2中的UE),本申请不作具体限定。在此情况下,信息1和信息2的指示方式也可以采用上述方式一至方式四中的任意一种方式,本申请不作具体限定。
针对第二种可能的方式下的第二种配置方式,在非共有的CC上承载group common PDCCH进行如下说明:
参见图9所示,CC group1和CC group2之间共有的CC为CC4。其中,CC1和CC5用来承载group common PDCCH,该CC1上的group common PDCCH用来承载CC1~CC4上的group UE common information,该CC5上的group common PDCCH用来承载CC4~CC7上的group UE common information。
基于此配置方式,基站分别向UE group1中每个UE发送信息1,向UE group2中每个UE发送信息2。信息1用于指示UE group1中每个UE在CC1上检测group common PDCCH,信息2用于指示UE group2中每个UE在CC5上检测group common PDCCH。下面以UE group1中UE1为例。基站向UE1发送信息1,该信息1用于指示UE1在CC1上检测group common PDCCH。具体的,信息1可以包括为所述UE配置的CC的索引值与承载group common PDCCH的CC的索引值,以及group common PDCCH包括的域之间的对应关系。从而UE1通过信息1能够确定在哪个CC上检测group common PDCCH,并且能够确定group UE common information的哪个域中包括哪个CC的group UE common information。比如参见表11所示。
表11
Figure PCTCN2018086282-appb-000010
Figure PCTCN2018086282-appb-000011
UE1在接收到信息1后,基于信息1在CC1上检测group common PDCCH,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field1获取CC1的group UE common information,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field2获取CC2的group UE common information,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field3获取CC3的group UE common information,在检测到的group common PDCCH上接收group UE common information,从该group UE common information的field4获取CC4的group UE common information。
通过上述方案,UE仅需要在基站指示的CC上检测group common PDCCH,并从group common PDCCH获取为UE配置的CC的group UE common information,从而降低了UE盲检测的次数,降低了UE的功耗。
另外,本申请实施例中,基站可以在为UE配置CC之前确定用于承载group UE common information的group common PDCCH所在的CC,从而在为UE配置CC时,仅需要保证配置给该UE的CC中包括承载该group common PDCCH的CC即可,不用每个UE必须配置某个CC,从而相比实施例一来说,能够提供为UE配置CC的灵活性。并且,在不同的CC group中共有的CC较多时,用于承载group common PDCCH的CC不为共有的CC时,为UE配置CC时,相比用于承载group common PDCCH的CC为共有的CC来说,能够进一步提高为UE配置CC的灵活性,使得系统的负载均衡。
参见图10所示,为本申请实施例提供的另一种信息传输方法流程示意图。该信息传输方法包括:
S1001,网络设备生成为所述终端设备配置的M个分量载波CC的组UE公共信息;
S1002,所述网络设备在N个CC上的至少一个组公共PDCCH上向所述终端设备发送为所述终端设备配置的M个CC的组UE公共信息,所述N为正整数,且小于或等于M,所述M为正整数。
其中,所述N个CC是为所述终端设备配置的M个CC中的N个。
S1003,终端设备在N个分量载波CC上检测至少一个组公共物理下行控制信道PDCCH,所述至少一个组公共PDCCH用于指示为所述终端设备配置的M个CC的组用户设备UE公共信息,所述N为正整数,且小于或等于M,所述M为正整数。
S1004,所述终端设备从检测到的所述至少一个组公共PDCCH接收为所述终端设备配置的M个CC的组UE公共信息。
通过上述方案,终端设备不需要检测所所有的CC来获取组公共PDCCH,仅需要在N个分量载波CC上检测至少一个组公共PDCCH来获取为所述终端设备配置的M个CC的组UE公共信息即可,减少了终端设备盲检测的次数,降低了终端设备的功耗。
本申请实施例中终端设备在哪个CC上检测至少一个组公共PDCCH,一种可能的实现方式是:可以通过静态配置的方式;另一种可能的实现方式是:通过半静态配置的方式,具体的,在终端设备在N个分量载波CC上检测至少一个组公共物理下行控制信道PDCCH之前,网络设备向终端设备发送所述第一信息,所述第一信息用于指示指示所述终端设备在所述N个CC上检测所述至少一个组公共PDCCH,从而所述终端设备接收所述网络设备发送的第一信息后,根据所述第一信息在N个分量载波CC上检测所述至少一个组公共PDCCH。
在通过静态配置的方式时:一个基站占用的所有的CC为一个CC组,即所有的CC组成一个CC group。在此场景下,可以静态配置在CC组中其中N个CC用来承载至少一个group common PDCCH。一个基站包括的所有的CC为多个CC group。基站可以配置在每个CC group中其中一个或者多个CC用来承载至少一个group common PDCCH,该至少一个group common PDCCH用来承载该CC group中所有CC的group UE common information。在不同的CC group之间包括有共有的CC时,可以通过共有的CC来承载group common PDCCH,该group common PDCCH来承载不同的CC group中包括的CC的group UE common information,当然也可以通过非共有的CC来承载group common PDCCH,在每个CC group中一个或者多个用来承载group common PDCCH,该group common PDCCH中承载该CC group中包括的CC的group UE common information。在不同的CC group之间包括有共有的CC时,在每个CC group中一个或者多个用来承载group common PDCCH,该group common PDCCH中承载该CC group中包括的CC的group UE common information。具体的,确定终端设备哪个CC上检测至少一个组公共PDCCH时,具体的配置方式可以参见图4至图9所示的实施例中所述的配置方式,在此不再赘述。
在通过半静态配置的方式指示终端设备哪个CC上检测至少一个组公共PDCCH,具体指示方式可以参见图4至图9所示的实施例中所述的指示方式,在此不再赘述。
