具体实施方式
下面结合本发明实施例中的附图对本发明实施例进行描述。
本发明实施例中所涉及的各网元的描述如下:
网络设备:可以为接入网(radio access network,RAN)设备,主要负责空口侧的无线资源管理、服务质量(quality of service,QoS)管理、数据压缩和加密等功能。网络设备可以包括各种形式的基站,例如:宏基站,微基站(也称为小站),中继站,接入点等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如,在第五代(5th generation,5G)系统中,称为gNB;在LTE系统中,称为演进的节点B(evolved nodeB,eNB或者eNodeB);在第三代(3rd generation,3G)系统中,称为节点B(node B)等。
本发明实施例中远端用户设备或中继用户设备可称为终端设备,或者可以称为用户设备(user equipment,UE),UE是通过接入网设备来实现接入网络侧的,例如可以是手持终端设备、笔记本电脑、用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant,PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)或者无线本地环路(wireless local loop,WLL)台、机器类型通信(machine type communication,MTC)终端等,例如,终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
例如,远端用户设备可以是一个低能力的设备,例如可穿戴设备,其特点为体积小,电池容量小,射频能力较低。因此,需要节省其消耗的功率,延长其待机时间。中继用户设备可以是一个高能力的设备,例如高能力的智能手机,其可以作为一个中继节点辅助低能力的设备连接网络,节省低能力设备的耗电。例如,未来每个人身上都会带各种各样的智能可穿戴设备,这些设备需要连接网络传输数据或建立语音电话业务。由于可穿戴设备与智能手机的距离远小于与基站之间的距离,如果这些设备可以通过智能手机中继连接到网络,那么可以降低可穿戴设备的功耗,并且可以提高可穿戴设备的传输速率。
可选的,本发明实施例的资源分配方法可以应用于D2D通信系统中的UE-to-Network relay场景。D2D通信即是发送端通过侧行链路将数据直接发送给接收端,无需通过eNB或者蜂窝网络进行中转的通信方式。UE-to-Network relay场景是D2D通信方式中一种比较特殊的方式。
如图1所示,即是本发明实施例提供的一种UE-to-Network relay场景的系统架构,如图 所示,该系统架构包括网络设备、中继UE以及远端UE,远端UE通过中继UE与网络设备进行连接,从而接入网络。需要说明的是,图1中仅仅表示了两个远端UE,但是这并不构成对本发明实施例的限定,本发明实施例不限定远端UE的个数。
基于图1的系统架构图,网络设备可以为中继UE、远端UE分配资源。如果是为中继UE分配的资源,则中继UE可以根据所分配的资源来发送数据或接收数据,例如,中继UE向远端UE发送数据所需的资源;或者,中继UE接收远端UE发送的数据所需的资源;或者例如,中继UE向网络设备发送数据所需的资源;或者,中继UE接收网络设备发送的数据所需的资源;如果是为远端UE分配的资源,则远端UE可以根据所分配的资源来发送数据或接收数据,例如,远端UE向中继UE发送数据所需的资源;或者,远端UE接收中继UE发送的数据所需的资源;或者,远端UE向网络设备发送数据所需的资源;或者,远端UE接收网络设备发送的数据所需的资源。
现有的资源分配方法包括:网络设备通过下行控制信息(Downlink Control Information,DCI)为中继UE、远端UE分配资源,其中,DCI中的资源分配字段可以指示出为UE分配的资源信息。然而,在至少一个远端UE通过中继UE与网络设备通信的场景中,网络设备可以发送用于调度中继UE或发送用于调度远端UE的DCI,而对于中继UE而言,需要检测用于调度中继UE或用于调度远端UE的DCI,如何区分DCI是用于调度中继UE还是调度远端UE的,仍是一个值得考虑的问题;对于远端UE而言,如何检测用于调度自身设备的DCI,依旧是一个值得考虑的问题。
在第一种可选的实现方案中,在本发明实施例中,中继UE接收网络设备发送的第一控制信息;中继UE根据第一信息确定第一控制信息用于调度目标设备,目标设备为以下设备中的一个:中继UE和至少一个远端UE,其中,至少一个远端UE通过中继UE与网络设备通信,第一信息包括以下至少一项:第一控制信息、加扰第一控制信息的无线网络临时标识、第一控制信息的负载大小、承载第一控制信息的PDCCH和第一控制信息所在的子帧;在目标设备为至少一个远端UE中的一个的情况下,中继UE根据第一控制信息包含的用于传输数据的资源信息确定第二控制信息,并向目标设备发送第二控制信息,以使目标设备根据第二控制信息传输数据;在目标设备为中继UE的情况下,中继UE根据第一控制信息传输数据。这样中继UE在接收到网络设备发送的第一控制信息之后,能够根据与第一控制信息相关的第一信息来确定该第一控制信息是调度中继UE和至少一个远端UE中的哪一个UE的。
在第二种可选的实现方案中,在本发明实施例中,中继UE接收网络设备发送的第一控制信息;中继UE根据第一信息,确定第一控制信息用于调度第一类设备或第二类设备,第一类设备为中继UE,第二类设备包括至少一个远端UE;其中,至少一个远端UE通过中继UE与网络设备通信;第一信息包括:第一控制信息包含的第一指示信息、加扰第一控制信息的无线网络临时标识、第一控制信息的负载大小、承载第一控制信息的PDCCH或第一控制信息所在的子帧。这样中继UE在接收到网络设备发送的第一控制信息之后,能够根据与第一控制信息相关的第一信息来确定该第一控制信息是调度哪一类设备的。
另外,在本发明实施例中,远端UE检测网络设备发送的第一控制信息;远端UE根据第一信息确定第一控制信息用于调度远端UE,其中,第一信息包括以下至少一项:第一控制信息的负载大小、承载第一控制信息的PDCCH和第一控制信息所在的子帧;远端UE根据第一控制信息传输数据。这样远端UE在接收到网络设备发送的第一控制信息之后,能够根据与第一控制信息相关的第一信息来确定该第一控制信息是否是调度该远端UE的。
需要说明的是,本发明实施例的方案除了可以应用在图1所示的系统架构图中,还可以应用于另一场景中,第一设备为接入网设备,如中继节点(Relay node)、传输接收点(transmission reception point,TRP)、中继传输接收点(relay transmission reception point,rTRP)或者基站;至少一个第二设备为用户设备;网络设备为为接入网设备,如继续演进的节点B(gNB)、传输接收点(transmission reception point,TRP)、施主传输接收点或归属传输接收点(donor transmission reception point,donor TRP)、锚传输接收点(anchor transmission reception point,anchor 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),网络设备可直接与核心网连接,至少一个第二设备通过第一设备与网络设备通信,第一设备可以通过无线连接到网络设备,第一设备还可以通过其他至少一个第一设备与网络设备连接。第一设备与网络设备之间的链路可称为回程链路(backhaul link)。第二设备与第一设备之间的链路可称为接入链路(access link)。网络设备可以为第一设备、第二设备分配资源。在通过DCI为第一设备和第二设备分配资源的场景中,对于第一设备而言,需要检测用于调度第一设备或用于调度第二设备的DCI,如何区分DCI是用于调度第一设备还是调度第二设备的,仍是一个值得考虑的问题;对于第二设备而言,如何检测用于调度自身设备的DCI,依旧是一个值得考虑的问题。
又一需要说明的是,本发明实施例所涉及的加扰控制信息可以指:控制信息进行循环冗余校验(Cyclic Redundancy Check,CRC)附着之后,使用RNTI对CRC校验位进行加扰;相应地,解扰控制信息指使用RNTI对信道解码后的序列中的CRC校验比特进行解扰。或者,本发明实施例所涉及的加扰控制信息还可以指:使用RNTI对控制信息进行CRC附着之后的序列加扰;相应地,解扰控制信息指使用RNTI对信道解码后的序列进行解扰。
基于图1所示的系统架构图,请参见图2,为本发明实施例提供了一种控制信息的处理方法。如图2所示,在该实施例中,包括第一设备、至少一个第二设备、以及网络设备,其中,第一设备以中继UE为例,至少一个第二设备中的每个第二设备以远端UE为例,该实施例中至少一个远端UE通过中继UE与网络设备进行通信。图2中的中继UE可以确定出第一控制信息所要调度的目标设备,其中目标设备为中继UE和至少一个远端UE中的任一个,其中目标远端UE为至少一个远端UE中的任意一个UE。
如图2所示,该控制信息的处理方法包括步骤201至步骤208,请参见以下具体介绍。
201,网络设备发送第一控制信息。
其中,第一控制信息包含了用于传输数据的资源信息。这里的资源信息可以包括资源频域信息、资源时域信息中的至少一项。
可选的,另外一种情况下,第一控制信息包含了传输数据所使用的参数、且不包含传输数据的资源信息。又一情况下,第一控制信息包含了传输数据所使用的参数和传输数据的资源信息。其中,这里提到的传输数据所使用的参数可以包括但不限定于功率参数、调制与编码策略(Modulation and Coding Scheme,MCS)。
相应地,中继UE接收网络设备发送的第一控制信息。可选的,中继UE还可以是检测、监测或解码网络设备发送的第一控制信息。
202,中继UE确定第一信息。
其中,该步骤是可选步骤。这里的第一信息是与第一控制信息相关的信息。例如,该第一信息可以包括以下至少一项:第一控制信息、加扰所述第一控制信息的无线网络临时标识、所述第一控制信息的负载大小、承载所述第一控制信息的PDCCH和所述第一控制信息所在的子帧。
接下来对第一信息中可以包括的每一项进行分别说明:
(1)第一信息可以包括加扰所述第一控制信息的无线网络临时标识(radio network temporary identity,RNTI)。是因为在网络设备通过控制信息分配用于传输数据的资源信息时,需要对控制信息进行加扰,且是通过RNTI来加扰的,只有采用加扰时所采用的RNTI对其进行解扰才能接收成功。当中继UE对第一控制信息接收成功之后,可以确定加扰第一控制信息的RNTI。另外,网络侧会为一个UE分配一个RNTI,即一个UE对应一个RNTI。在本实施例中,中继UE与至少一个远端UE的RNTI可以相同;或者,中继UE与至少一个远端UE的RNTI可以不相同;或者,中继UE与部分远端UE的RNTI相同,剩余远端UE的RNTI也可以相同或者不相同。
例如,网络设备为设备1分配了RNTI 1,如果网络设备为该设备1分配资源信息且通过控制信息来指示该资源信息,则网络设备会采用RNTI 1对该控制信息进行加扰,并发送加扰后的控制信息。检测到该加扰后的控制信息的设备,只有通过RNTI 1对其进行解扰,才能确定网络设备所分配的资源信息。
(2)第一信息可以包括第一控制信息,这里是指第一控制信息包含的指示信息。在中继UE对加扰后的第一控制信息接收成功之后,可以确定该第一控制信息所包含的指示信息。例如,该指示信息可以是第一指示信息,可以用于确定第一控制信息是用于调度中继UE和至少一个远端UE中的哪一个用户设备,即该第一指示信息与一个UE的标识相对应;又如,该指示信息可以是第二指示信息,该第二指示信息可以结合其他参数来确定第一控制信息是用于调度中继UE和至少一个远端UE中的哪一个用户设备,即该第二指示信息与至少两个UE的标识相对应。
(3)第一信息可以包括第一控制信息的负载大小。这里所说的第一控制信息的负载大小是指第一控制信息的所占用的比特数。例如,30bit或32bit等等。在中继UE对加扰后的第一控制信息接收成功之后,可以确定该第一控制信息所占用的比特数。
(4)第一信息可以包括承载所述第一控制信息的物理下行控制信道(Enhanced Physical Downlink Control Channel,PDCCH)。在中继UE对加扰后的第一控制信息接收成功之后,可以确定承载该第一控制信息的PDCCH。通过将控制信息所调度的设备与承载该控制信息的PDCCH相对应,能够实现根据承载控制信息的PDCCH来确定该第一控制信息所调度的是哪一个设备。
举例来说,请参见图3,为本发明实施例提供了一种无线帧的可能的结构。如图3所示,一个10ms的无线帧包含10个子帧,每个子帧均为1ms,一个子帧中包含至少两个候选PDCCH,可以按照预设规则将至少两个候选PDCCH划分为至少两个候选PDCCH集合,不同候选PDCCH集合所承载的控制信息用于调度不同的设备。
需要说明的是,从图2以及其他附图对应实施例中,所涉及的承载所述第一控制信息的PDCCH,还可以是增强型物理下行控制信道(Enhanced Physical Downlink Control Channel,EPDCCH),EPDCCH与PDCCH均可以用于承载第一控制信息。在本发明实施例中采用PDCCH进行说明,对于采用EPDCCH承载第一控制信息的情况可以参考采用PDCCH承载 第一控制信息的详细描述进行类推,在这不再赘述。
(5)第一信息可以包括第一控制信息所在的子帧。在中继UE对加扰后的第一控制信息解扰成功之后,可以确定第一控制信息所在的子帧。由于多个子帧可以用于传输控制信息,因此可以将控制信息所调度的设备与第一控制信息所在的子帧相对应,能够实现根据第一控制信息所在的子帧来确定该第一控制信息所调度的是哪一个设备。
举例来说,结合图3,一个无线帧中包含10个子帧,在实际中10子帧中的多个子帧可以用于发送控制信息,因可以按照预设规则将允许用于发送控制信息进行分类,划分为至少两个候选子帧集合,不同候选子帧集合所发送的控制信息用于调度不同的设备。
需要说明的是,从图2以及其他附图对应实施例中,所涉及的第一控制信息所在子帧,还可以是第一控制信息所在的时隙、小/微时隙、符号(比如正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号)等。在本发明实施例中对第一控制信息所在的子帧进行说明,对于第一控制信息所在的时隙、小/微时隙、符号的情况可以参考采用第一控制信息所在的子帧的详细描述进行类推,在这不再赘述。
203,中继UE根据第一信息确定第一控制信息用于调度该中继UE。
204,中继UE根据第一信息确定第一控制信息用于调度至少一个远端UE中的目标远端UE。
针对步骤203和步骤204而言,接下来根据不同第一信息的情况进行详细描述。
(1)在第一种可能的实现方案中,第一信息包括加扰第一控制信息的RNTI。中继UE根据加扰第一控制信息的RNTI确定第一控制信息用于调度哪一个用户设备。
举例来说,7个远端UE通过中继UE与网络设备通信,不同UE与一个RNTI一一对应。请参见表1,为RNTI与设备标识的映射关系。其中,RNTI 0至RNTI 7是用于对7个远端UE和中继UE的第一控制信息加扰的RNTI。
表1 RNTI与设备标识的映射关系
Figure PCTCN2018087215-appb-000001
在网络设备需要发送用于调度中继UE的第一控制信息的情况下,可以按照中继UE ID对应的“RNTI 0”对第一控制信息进行加扰;同理,在网络设备需要发送用于调度远端UE 5的第一控制信息的情况下,可以按照远端UE5 ID对应的“RNTI 5”来对第一控制信息进行加扰。这样在中继UE检测或接收到该第一控制信息的情况下,可以先确定将第一控制信息解扰成功的RNTI,再确定与该RNTI相对应的设备标识,进而确定第一控制信息是用于调度哪个UE的。
可选的,RNTI与设备标识的映射关系可以是网络设备通知中继UE的,这样中继UE可以确定每个与其连接的远端UE对应的RNTI,以便于在检测或接收第一控制信息时,按照映射关系中的各个RNTI分别对其进行解扰,一旦查找到解扰成功的RNTI,即可确定该第一控制信息所调度的UE。
(2)在第二种可能的实现方案中,第一控制信息包含第一指示信息,第一信息包括该第 一控制信息包含的第一指示信息。中继UE根据第一指示信息确定第一控制信息用于调度哪一个用户设备。
举例来说,7个远端UE通过中继UE与网络设备通信,第一指示信息在第一控制信息为3个比特的字段,请参见表2,为第一指示信息与设备标识的映射关系。其中,8个第一指示信息与7个远端UE和中继UE的标识一一对应。在该举例中,第一指示信息在第一控制信息中占用三个比特的位置,本发明实施例对第一指示信息所占用的比特数不做限定。
表2 第一指示信息与设备标识的映射关系
Figure PCTCN2018087215-appb-000002
在网络设备需要发送用于调度中继UE的第一控制信息的情况下,可以按照中继UE ID对应的第一指示信息“000”来写入相应字段;同理,在网络设备需要发送用于调度远端UE 5的第一控制信息的情况下,可以按照远端UE5 ID对应的第一指示信息“101”来写入相应字段。这样在中继UE检测或接收到该第一控制信息的情况下,可以根据第一控制信息来确定所调度的设备。
可以理解的是,由于可以通过第一控制信息中的第一指示信息区分第一控制信息用于调度哪个UE,因此,用于调度不同UE的控制信息可以使用相同的RNTI加扰,这样,中继UE仅需要根据一个RNTI来确定搜索空间,减少了搜索空间的确定次数,减少第一控制信息的解扰次数,进而降低了检测PDCCH的复杂度,加快了第一指示信息的确定效率。
(3)在第三种可能的实现方案中,第一信息可以包括加扰第一控制信息的RNTI和第一控制信息所包括的第二指示信息。通过这两个参数结合的方式来确定第一控制信息所调度的UE。
举例来说,7个远端UE通过中继UE与网络设备通信,请参见表3,为RNTI与设备标识的映射关系,以及第二指示信息与设备标识的映射关系。其中,RNTI 0和RNTI 1是用于对7个远端UE和中继UE的第一控制信息加扰的RNTI;第二指示信息为第一控制信息所包含的字段。在该举例中,第二指示信息在第一控制信息中占用两个比特的位置,本发明实施例对第二指示信息所占用的比特数不做限定。
表3 RNTI与设备标识的映射关系以及第二指示信息与设备标识的映射关系
Figure PCTCN2018087215-appb-000003
在网络设备需要发送用于调度中继UE的第一控制信息的情况下,可以按照中继UE ID对应的“RNTI 0”对第一控制信息进行加扰,并在该第一控制信息中第二指示信息的字段写入“00”;同理,在网络设备需要发送用于调度远端UE 5的第一控制信息的情况下,可以按照远端UE5 ID对应的“RNTI 1”来对第一控制信息进行加扰,并在该第一控制信息中第二指示信息的字段写入“01”。这样在中继UE检测或接收到该第一控制信息的情况下,可以先确定将第一控制信息接收成功的RNTI,再确定该第一控制信息所包含的第二指示信息,进而确定出与该RNTI和该第二指示信息均相对应的设备标识,进而确定第一控制信息是用于调度的UE。
(4)在第四种可能的实现方案中,第一信息可以包括加扰第一控制信息的RNTI和承载第一控制信息的PDCCH。通过这两个参数结合的方式来确定第一控制信息所调度的UE。
举例来说,15个远端UE通过中继UE与网络设备通信,请参见表4,为RNTI与设备标识的映射关系,以及承载第一控制信息的PDCCH与设备标识的映射关系。其中,RNTI 0和RNTI 1是用于对15个远端UE和中继UE的第一控制信息加扰的RNTI;用于调度15个远端UE和中继UE的第一控制信息是承载在以下PDCCH0至PDCCH3来发送的。

RNTI 3 远端UE 12 ID 远端UE 13 ID 远端UE 14 ID 远端UE 15 ID
在网络设备需要发送用于调度中继UE的第一控制信息的情况下,可以按照中继UE ID对应的“RNTI 0”对第一控制信息进行加扰,并在子帧中PDCCH 0的位置来发送第一控制信息;同理,在网络设备需要发送用于调度远端UE 5的第一控制信息的情况下,可以按照远端UE5 ID对应的“RNTI 1”来对第一控制信息进行加扰,并在子帧中PDCCH 1的位置来发送第一控制信息。这样在中继UE检测或接收到该第一控制信息的情况下,可以确定将第一控制信息接收成功的RNTI,并确定承载该第一控制信息的PDCCH,进而确定出与该RNTI和该PDCCH均相对应的设备标识,进而确定第一控制信息是用于调度的UE。
可选的,在实际中,承载调度不同UE的第一控制信息的候选PDCCH是由同一RNTI确定的搜索空间中的,例如,搜索空间是由网络设备给中继UE分配的RNTI来确定的。承载调度不同UE的第一控制信息的候选PDCCH也可以由不同RNTI确定的搜索空间中的,例如,承载第一控制信息的候选PDCCH是根据加扰该第一控制信息的RNTI确定的搜索空间中的。例如,承载调度远端UE 1的第一控制信息的PDCCH是根据RNTI 0确定的搜索空间中的候选PDCCH 1。承载用于调度远端UE 5的第一控制信息的PDCCH是根据RNTI 1确定的搜索空间中的候选PDCCH 1。
需要说明的是,在图2及其他附图对应的实施例中所涉及的搜索空间为至少两个候选物理下行控制信道的集合,一个候选PDCCH在聚合的一个或多个控制信道单元(Control Channel Elements,CCE)上传输,聚合的CCE的数量为该候选PDCCH的聚合等级。

(5)在第五种可能的实现方案中,第一信息可以包括加扰第一控制信息的RNTI和第一控制信息所在的子帧。通过这两个参数结合的方式来确定第一控制信息所调度的UE。
举例来说,15个远端UE通过中继UE与网络设备通信,请参见表6,为RNTI与设备标识的映射关系,以及第一控制信息所在的子帧与设备标识的映射关系。其中,RNTI 0和RNTI 1是用于对15个远端UE和中继UE的第一控制信息加扰的RNTI;用于调度15个远端UE和中继UE的第一控制信息所在的子帧包括子帧0到子帧7的位置。
表6 RNTI与设备标识的映射关系以及第一控制信息所在的子帧与设备标识的映射关系
Figure PCTCN2018087215-appb-000009
在网络设备需要发送用于调度中继UE的第一控制信息的情况下,可以按照中继UE ID对应的“RNTI 0”对第一控制信息进行加扰,并在“子帧0”的位置来发送第一控制信息;同理,在网络设备需要发送用于调度远端UE 5的第一控制信息的情况下,可以按照远端UE 13 ID对应的“RNTI 1”来对第一控制信息进行加扰,并在“子帧5”的位置来发送第一控制信息。这样 在中继UE检测或接收到该第一控制信息的情况下,可以确定将第一控制信息接收成功的RNTI,并确定该第一控制信息所在的子帧,进而确定出与该RNTI和该子帧均相对应的设备标识,进而确定第一控制信息是用于调度的UE。
(6)在第六种可能的实现方案中,第一信息可以包括第一控制信息包含的第二指示信息和承载第一控制信息的PDCCH。通过这两个参数结合的方式来确定第一控制信息所调度的UE。
举例来说,7个远端UE通过中继UE与网络设备通信,请参见表7,为第二指示信息与设备标识的映射关系,以及承载第一控制信息的PDCCH与设备标识的映射关系。其中,第二指示信息为第一控制信息所包含的字段;承载调度7个远端UE和中继UE的第一控制信息是在以下PDCCH0至PDCCH3的位置来发送的。在该举例中,第二指示信息在第一控制信息中占用1个比特的位置,本发明实施例对第二指示信息所占用的比特数不做限定。

第二指示信息为0 中继UE ID 远端UE 1 ID 远端UE 2 ID 远端UE 3 ID
第二指示信息为1 远端UE 4 ID 远端UE 5 ID 远端UE 6 ID 远端UE 7 ID
在网络设备需要发送用于调度中继UE的第一控制信息的情况下,可以在第一控制信息中第二指示信息的字段写入“0”,并在子帧中PDCCH 0的位置来发送第一控制信息;同理,在网络设备需要发送用于调度远端UE 5的第一控制信息的情况下,可以第一控制信息中第二指示信息的字段写入“1”,并在子帧中PDCCH 1的位置来发送第一控制信息。这样在中继UE检测或接收到该第一控制信息,可以确定第一控制信息所包含的第二指示信息,并确定承载该第一控制信息的PDCCH,进而确定出与该第二指示信息和该PDCCH均相对应的设备标识,进而确定第一控制信息是用于调度的UE。
(7)在第七种可能的实现方案中,第一信息可以包括第一控制信息包含的第二指示信息和第一控制信息所在子帧。通过这两个参数结合的方式来确定第一控制信息所调度的UE。
举例来说,15个远端UE通过中继UE与网络设备通信,请参见表8,为第二指示信息与设备标识的映射关系,以及第一控制信息所在子帧与设备标识的映射关系。其中,第二指示信息为第一控制信息所包含的字段;用于调度15个远端UE和中继UE的第一控制信息所在的子帧包括子帧0到子帧7的位置。在该举例中,第二指示信息在第一控制信息中占用1个比特的位置,本发明实施例对第二指示信息所占用的比特数不做限定。
表8 第二指示信息与设备标识的映射关系以及第一控制信息所在子帧与设备标识的映射关系
Figure PCTCN2018087215-appb-000010
在网络设备需要发送用于调度中继UE的第一控制信息的情况下,可以在第一控制信息 中第二指示信息的字段写入“0”,并在“子帧0”的位置来发送第一控制信息;同理,在网络设备需要发送用于调度远端UE 13的第一控制信息的情况下,可以第一控制信息中第二指示信息的字段写入“1”,并在“子帧0”的位置来发送第一控制信息。这样在中继UE检测或接收到该第一控制信息的情况下,可以确定第一控制信息所包含的第二指示信息,并确定该第一控制信息所在的子帧,进而确定出与该第二指示信息和该子帧均相对应的设备标识,进而确定第一控制信息是用于调度的UE。
可选的,在第六种可能的实现方案和第七种可能实现方案,以及其他未通过加扰第一控制信息的RNTI来确定第一控制信息所调度的是哪个UE的方案中,用于加扰本发明实施例中的调度不同UE的第一控制信息的RNTI是相同的。这样,中继UE仅需要根据这一个RNTI来确定搜索空间,减少了搜索空间的确定次数,减少第一控制信息的解扰次数,进而降低了检测PDCCH的复杂度,加快了对第一控制信息的确定效率。
可选的,在以上第一种可能的实现方案至第七种可能的实现方案,以及其他未通过第一控制信息的负载大小来确定第一控制信息所调度的是哪个UE的方案中,用于调度中继UE的第一控制信息的负载大小和用于调度至少一个远端UE的第一控制信息的负载大小可以相同。由于在确定第一控制信息的负载大小的过程中,对于每一种类型的负载大小,中继UE均需要执行一次信道解码,因此通过设定第一控制信息的负载大小相同,则中继UE仅需执行一次信道解码,加快了对第一控制信息的确定效率。
在第八种可能的实现方案中,第一信息可以包括第一控制信息的负载大小,通过设定不同负载大小与不同设备标识的映射关系,使得中继UE在对第一控制信息接收成功之后先确定第一控制信息的负载大小,进而确定与该负载大小相对应的设备标识,进而确定该第一控制信息所调度的UE。具体实现方式同第一种可能的实现方案或第二种可能的实现方案相同,不同的是在该实现方案中与设备标识对应的为第一控制信息的负载大小。可选的,第一信息在包括第一控制信息的情况下,还可以结合其他参数来确定第一控制信息所调度的UE,在这里不再一一枚举。
需要说明的是,按照第一信息可以包括的各项参数,还存在其他组合方式,在这里不再一一举例说明,均可以按照与设备标识建立映射关系的方式,来实现中继UE确定第一控制信息所调度的UE。
可选的,在本发明实施例以上所提到的映射关系以及未一一进行举例的其他可能的实现方案中的映射关系RNTI与设备标识的映射关系可以是网络设备通知中继UE的,以便于中继UE确定第一控制信息所调度的UE。
205,中继UE根据第一控制信息传输数据。
其中,在步骤203中继UE确定第一控制信息是用于调度中继UE自身的情况下,中继UE根据第一控制信息来传输数据。举例来说,第一控制信息所包含的资源信息是用于向第一远端UE发送数据的,则中继UE在该资源信息上向该第一远端UE传输数据;或者,第一控制信息所包含的资源信息是用于接收第二远端UE发送的数据的,则中继UE在该资源信息接收第二远端UE发送的数据。其中第一远端UE或第二远端UE是至少一个远端UE中的任意一个。
可选的,在第一控制信息包含传输数据所使用的参数的情况下,中继UE根据该参数来传输数据。
可选的,在第一控制信息包含传输数据所使用的参数和资源信息的情况下,中继UE根 据该参数和资源信息来传输数据。
206,中继UE根据第一控制信息包含的用于传输数据的资源信息确定第二控制信息。
其中,在步骤204中继UE根据第一信息确定第一控制信息用于调度至少一个远端UE中的目标远端UE的情况下,中继UE根据第一控制信息包含的用于传输数据的资源信息确定第二控制信息。具体资源信息所包含的内容可以参见步骤201中具体介绍,在此不再赘述。中继UE所确定的第二控制信息包含该资源信息,以使在将第二控制信息发送给目标远端UE之后,目标远端UE可以确定可以用于传输数据的资源信息。
可选的,对于第一控制信息包含了传输数据所使用的参数、且不包含传输数据的资源信息的情况,中继UE根据第一控制信息包含的传输数据所使用的参数确定第二控制信息。
可选的,对于第一控制信息包含了传输数据所使用的参数和传输数据的资源信息,中继UE根据第一控制信息包含的传输数据所使用的参数和传输数据的资源信息确定第二控制信息。
207,中继UE向目标远端UE发送第二控制信息。
其中,在中继UE确定第二控制信息之后,中继UE向远端UE发送该第二控制信息。
相应的,目标远端UE接收该第二控制信息。
208,目标远端UE根据第二控制信息传输数据。
其中,在步骤207目标远端UE接收到第二控制信息的情况下,目标远端UE根据第二控制信息来传输数据。举例来说,第二控制信息所包含的资源信息是用于向中继UE发送数据的,则目标远端UE在该资源信息上向该中继UE传输数据;或者,第二控制信息所包含的资源信息是用于接收中继UE发送的数据的,则目标远端UE在该资源信息接收中继UE发送的数据。
可选的,在第一控制信息包含传输数据所使用的参数的情况下,目标远端UE根据该参数来传输数据。
可选的,在第一控制信息包含传输数据所使用的参数和资源信息的情况下,目标远端UE根据该参数和资源信息来传输数据。
在本发明实施例中,中继UE在接收到网络设备发送的第一控制信息之后,能够根据与第一控制信息相关的第一信息来确定该第一控制信息是调度中继UE和至少一个远端UE中的哪一个UE的。
基于图1所示的系统架构图,请参见图4,为本发明实施例提供了一种控制信息的处理方法。如图4所示,在该实施例中,包括第一设备、至少一个第二设备、以及网络设备,其中,第一设备以中继UE为例,至少一个第二设备中的每个第二设备以远端UE为例,该实施例中至少一个远端UE通过中继UE与网络设备进行通信。图4中的中继UE可以确定出第一控制信息所要调度的目标设备,其中目标设备为中继UE和至少一个远端UE中的任一个。
401,网络设备发送第一控制信息。
其中,步骤401可以参见图2所示实施例中步骤201的详细描述,在此不再赘述。
402,中继UE确定第一信息。
其中,该步骤是可选步骤。这里的第一信息是与第一控制信息相关的信息。这里的第一信息与图2所示实施例中的第一信息不同。例如,第一信息包括:所述第一控制信息包含的第一指示信息、加扰所述第一控制信息的无线网络临时标识、所述第一控制信息的负载大小、 承载所述第一控制信息的PDCCH或所述第一控制信息所在的子帧。
中继UE可以根据第一信息确定第一控制信息所调度设备分类包括第一类设备和第二类设备,第一类设备为中继UE,所述第二类设备包括至少一个远端UE。
接下来对第一信息中可以包括的每一项进行分别说明:
(1)第一信息可以包括加扰所述第一控制信息的RNTI。是因为在网络设备通过控制信息分配用于传输数据的资源信息时,需要对控制信息进行加扰,且是通过RNTI来加扰的,只有采用加扰时所采用的RNTI对其进行解扰才能接收成功。当中继UE对第一控制信息接收成功之后,可以确定加扰第一控制信息的RNTI。另外,网络侧会为一个UE分配一个RNTI,即一个UE对应一个RNTI。在本实施例中,中继UE与至少一个远端UE的RNTI不相同。
例如,网络设备为设备1分配了RNTI 1,如果网络设备为该设备1分配资源信息且通过控制信息来指示该资源信息,则网络设备会采用RNTI 1对该控制信息进行加扰,并发送加扰后的控制信息。检测到该加扰后的控制信息的设备,只有通过RNTI 1对其进行解扰,才能确定网络设备所分配的资源信息。
(2)第一信息可以包括第一控制信息,这里是指第一控制信息包含的指示信息。在中继UE对加扰后的第一控制信息接收成功之后,可以确定该第一控制信息所包含的指示信息。
(3)第一信息可以包括第一控制信息的负载大小。这里所说的第一控制信息的负载大小是指第一控制信息的所占用的比特数。例如,30bit或32bit等等。在中继UE对加扰后的第一控制信息接收成功之后,可以确定该第一控制信息所占用的比特数。(4)第一信息可以包括承载所述第一控制信息的PDCCH。在中继UE对加扰后的第一控制信息接收成功之后,可以确定承载该第一控制信息的PDCCH。
举例来说,结合图2所示实施例中无线帧中PDCCH的介绍,即一个子帧中包含至少两个候选PDCCH,可以按照预设规则将至少两个候选PDCCH划分为至少两个候选PDCCH集合,不同候选PDCCH集合所承载的控制信息用于调度不同的设备分类。
(5)第一信息可以包括第一控制信息所在的子帧。在中继UE对加扰后的第一控制信息接收成功之后,可以确定第一控制信息所在的子帧。由于多个子帧可以用于传输控制信息,因此可以将控制信息所调度的设备分类与第一控制信息所在的子帧相对应,能够实现根据第一控制信息所在的子帧来确定该第一控制信息是用于调度第一类设备或第二类设备。
举例来说,结合图3,即多个子帧可以用于发送控制信息,可以按照预设规则将允许用于发送控制信息进行分类,划分为至少两个候选子帧集合,不同候选子帧集合所发送的控制信息用于调度不同的设备分类。
403,中继UE根据第一信息确定第一控制信息用于调度第一类设备。
404,中继UE根据第一信息确定第一控制信息用于调度第二类设备。
针对步骤403和步骤404而言,接下来根据不同第一信息的情况进行详细描述。在本发明实施例中所涉及的设备分类包括第一类设备和第二类设备,第一类设备为中继UE;第二类设备为至少一个远端UE。
(1)在第一种可能的实现方案中,第一信息包括加扰第一控制信息的RNTI。中继UE根据加扰第一控制信息的RNTI确定第一控制信息用于调度第一类设备或第二类设备。
举例来说,加扰调度第一类设备的控制信息的RNTI和加扰调度第二类设备的控制信息的RNTI不同。7个远端UE通过中继UE与网络设备通信,请参见表9,为一种RNTI与设备标识的映射关系。其中,第一类设备的RNTI为与中继UE ID对应的RNTI 0,第二类设备 的RNTI为与至少一个远端UE ID对应的RNTI 1。又如,请参见表10,为又一种RNTI与设备标识的映射关系。其中,第一类设备的RNTI为与中继UE ID对应的RNTI 0,第二类设备的RNTI为与至少一个远端UE ID对应的RNTI 1、RNTI2、RNTI3。
表9 RNTI与设备标识的映射关系
Figure PCTCN2018087215-appb-000011
表10 RNTI与设备标识的映射关系
Figure PCTCN2018087215-appb-000012
以上表9和表10的这两种方式均可以使得第一类设备和第二类设备的RNTI不相同,本发明实施例不限定至少一个远端UE对应的RNTI的数量。以表10为例,在网络设备需要发送用于调度中继UE的第一控制信息的情况下,可以按照中继UE ID对应的“RNTI 0”对第一控制信息进行加扰;同理,在网络设备需要发送用于调度远端UE 5的第一控制信息的情况下,可以按照远端UE5 ID对应的“RNTI 3”来对第一控制信息进行加扰。这样在中继UE检测或接收到该第一控制信息的情况下,可以先确定将第一控制信息接收成功的RNTI,进而确定第一控制信息是用于调度哪个设备分类。
可选的,RNTI与设备标识的映射关系可以是网络设备通知中继UE的,这样中继UE可以确定第一类设备和第二设备所对应的RNTI,以便于在检测第一控制信息时,按照映射关系中的各个RNTI分别对其进行解扰,一旦查找到接收成功的RNTI,即可确定该第一控制信息所调度的设备分类。
可选的,检测用于调度远端UE的第一控制信息的搜索空间与检测用于调度中继UE的第一控制信息的搜索空间相同。可选的,搜索空间根据用于调度中继UE的第一控制信息的加扰的RNTI确定。或者,搜索空间根据其他用于调度中继UE的其他控制信息(非第一控制信息)的加扰的RNTI确定(是因为中继UE可能被配置多种RNTI,不同的RNTI加扰不同的控制信息)。这样,中继UE可以在相同的搜索空间中检测PDCCH,减少了检测PDCCH的复杂度。
可选的,在搜索空间中用于调度远端UE的第一控制信息的负载大小等于在同一搜索空间中用于调度中继UE的第一控制信息的负载大小。这里的用于调度中继UE的第一控制信息可以是用于调度中继UE的第一控制信息,也可以是用于调度中继UE的其他控制信息,即第三控制信息(例如,第三控制信息包括中继UE向基站发送数据所使用的资源,或者中继UE接收基站发送数据的资源)。例如,第一控制信息和第三控制信息以DCI进行举例,中继UE在根据小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI)确 定的搜索空间中需要检测/解码承载DCI format 0(第三控制信息)的PDCCH,则在根据C-RNTI确定的搜索空间中用于调度远端UE的DCI的负载大小等于DCI format 0的负载大小。又如,中继UE在根据C-RNTI确定的搜索空间中需要检测/解码承载DCI format 0的PDCCH及承载DCI format 1的PDCCH,且这两个DCI的负载大小不同,则在根据C-RNTI确定的搜索空间中用于调度远端UE的DCI的负载大小可以等于DCI format 0的负载大小,也可以等于DCI format 1的负载大小。在这种方法中,用于调度远端UE的DCI可以有两种负载大小。可以通过在用于调度远端UE的DCI信息的基础上填充0,使得负载大小相等。或者,通过在用于调度中继UE的DCI信息的基础上填充0,使得负载大小相等。
(2)在第二种可能的实现方案中,第一控制信息包含第一指示信息,第一信息包括该第一控制信息包含的第一指示信息。中继UE根据第一指示信息确定第一控制信息用于调度第一类设备或第二类设备。
举例来说,网络设备为第一类设备和第二类设备在第一控制信息中设定不同比特值的第一指示信息。7个远端UE通过中继UE与网络设备通信,第一指示信息在第一控制信息为1个比特的字段,请参见表11,为第一指示信息与设备标识的映射关系。其中,第一类设备的第一指示信息为与中继UE ID对应的“0”,第二类设备的第一指示信息为与至少一个远端UE ID对应的“1”。
表11 第一指示信息与设备标识的映射关系
Figure PCTCN2018087215-appb-000013
在网络设备需要发送用于调度中继UE的第一控制信息的情况下,可以按照中继UE ID对应的第一指示信息“0”来写入相应字段;同理,在网络设备需要发送用于调度远端UE 5的第一控制信息的情况下,可以按照远端UE5 ID对应的第一指示信息“1”来写入相应字段。这样在中继UE检测或接收到该第一控制信息的情况下,可以根据第一控制信息来确定所调度的设备分类。
表11中第二类设备的第一指示信息是相同的。在可选的方案中,第二类设备包含的至少一个远端UE对应的第一指示信息可以不同,且保证至少一个远端UE对应的第一指示信息与第一类设备的第一指示信息不同。在本发明实施例中不限定第一指示信息在第一控制信息中所占用的比特数。
可以理解的是,用于调度不同设备类别的控制信息可以使用相同的RNTI加扰,这样,中继UE仅需要根据这一个RNTI来确定搜索空间,减少了搜索空间的确定次数,减少第一控制信息的解扰次数,进而降低了检测PDCCH的复杂度,加快了第一指示信息的确定效率。
(3)在第三种可能的实现方案中,第一信息可以包括第一控制信息的负载大小,通过设定不同负载大小与不同设备类别的映射关系,使得中继UE在对第一控制信息接收成功之后先确定第一控制信息的负载大小,进而确定与该负载大小相对应的设备分类,进而确定该第一控制信息所调度的设备分类。
举例来说,第一控制信息为DCI,网络设备为第一类设备和第二类设备的DCI设定不同负载大小。7个远端UE通过中继UE与网络设备通信,请参见表12,为负载大小与设备标 识的映射关系。其中,M1和M2为大于0的整数,且M1不等于M2。可选的,第一类设备的DCI和第二类设备的DCI是不同的DCI格式,且DCI的负载大小不同。第一类设备的负载大小为与中继UE ID对应的M1比特,第二类设备的负载大小为与至少一个远端UE ID对应的M2比特。
表12 负载大小与设备标识的映射关系
Figure PCTCN2018087215-appb-000014
在网络设备需要发送用于调度中继UE的第一控制信息的情况下,可以按照中继UE ID对应的控制信息的负载大小来生成第一控制信息;同理,在网络设备需要发送用于调度远端UE 5的第一控制信息的情况下,可以按照远端UE5 ID对应的控制信息的负载大小来生成第一控制信息。这样在中继UE检测或接收到该第一控制信息的情况下,可以确定第一控制信息的负载大小,进而确定第一控制信息所调度的设备分类。
表12中第二类设备的DCI的负载大小是相同的。在可选的方案中,第二类设备包含的至少一个远端UE对应的负载大小也可以不同,且保证至少一个远端UE对应的负载大小与第一类设备的负载大小不同。
可选的,实际中可以通过在用于调度remote UE的控制信息的基础上填充0,使得负载大小不相同。或者,通过在用于调度relay UE的控制信息的基础上填充0,使得负载大小不相同。
可选的,若第一控制信息为DCI的情况下,第一控制信息可以设定为与用于调度中继UE的其他控制信息的负载相同,例如,用于调度中继UE的DCI的负载大小与DCI format 0的负载相同;用于调度远端UE的DCI的负载大小与DCI format 1,或DCI format 2A,或者DCI format 2,或者DCI format 1D,或者DCI format 1B,或者DCI format 2B,或者DCI format 2C,或者DCI format 2D的负载大小相同。进一步可选的,中继UE根据其传输模式(transmission mode)确定用于调度远端UE的DCI的负载大小与上述哪种DCI的负载相等,比如,中继UE的传输模式为1时,用于调度远端UE的DCI的负载大小与DCI format 1的负载大小相同。当中继UE的传输模式为3时,用于调度远端UE的DCI的负载大小与DCI format 2A的负载大小相同。其中,DCI format 0,与DCI format 1,或DCI format 2A,或者DCI format 2,或者DCI format 1D,或者DCI format 1B,或者DCI format 2B,或者DCI format 2C,或者DCI format 2D的负载大小不同。
(4)在第四种可能的实现方案中,第一信息包括承载第一控制信息的PDCCH。承载第一控制信息的PDCCH可以用于确定第一控制信息用于调度第一类设备或第二类设备。
举例来说,网络设备为第一类设备和第二类设备分配不同PDCCH来承载第一控制信息。4个远端UE通过中继UE与网络设备通信,请参见表13,为承载第一控制信息的PDCCH与设备标识的映射关系。其中,承载调度第一类设备的第一控制信息是在PDCCH1的位置来发送的;承载调度第二类设备的第一控制信息是在PDCCH0的位置来发送的。
表13 承载第一控制信息的PDCCH与设备标识的映射关系
  PDCCH 0 PDCCH 1 PDCCH 1 PDCCH 1 PDCCH 1
设备标识 中继UE ID 远端UE 1 ID 远端UE 2 ID 远端UE 3 ID 远端UE 4 ID
在网络设备需要发送用于调度中继UE的第一控制信息的情况下,可以在子帧中PDCCH 0的位置来发送第一控制信息;同理,在网络设备需要发送用于调度远端UE 4的第一控制信息的情况下,可以在子帧中PDCCH 1的位置来发送第一控制信息。这样在中继UE检测或接收到该第一控制信息且接收成功的情况下,可以先确定承载该第一控制信息的PDCCH,进而确定第一控制信息所调度的设备分类。
表13中承载第二类设备的第一控制信息的PDCCH是相同的。在可选的方案中,承载调度第二类设备包含的至少一个远端UE的第一控制信息的PDCCH可以不同,且保证与承载调度第一类设备的第一控制信息的PDCCH不同。
在实际中,在一个搜索空间中包含多个候选PDCCH,一部分候选PDCCH用于承载调度中继UE的第一控制信息,另一部分候选PDCCH用于承载调度远端UE的第一控制信息。可选的,所述搜索空间是根据中继UE的RNTI确定的。
一种可能的方案中,在某种聚合等级下所述搜索空间的一个候选PDCCH的索引用m来表示,m=0,1,…,M-1,其中,M为所述搜索空间中候选PDCCH的数量。
则承载调度远端UE的第一控制信息的候选PDCCH为候选PDCCH m1,m1=0,1,…,M1-1,其中M1<M;承载调度中继UE的第一控制信息的候选PDCCH为候选PDCCH m2,m2=M1,M1+1,…,M-1。M1可以在标准协议中规定,或者是网络设备配置的,或者是中继UE自己确定的。在中继UE自己确定的情况下,中继UE需要向网络设备发送指示信息,用于指示M1。
可选的,对于不同的聚合等级,M1可以是不同的。
可选的,M1为M乘以一个比例因子k,0<k<=1。对于不同的聚合等级,该比例因子是相同的。
中继UE若确定承载第一控制信息的PDCCH为候选PDCCH m1时,中继UE确定该PDCCH承载的第一控制信息是调度远端UE的。中继UE若确定承载第一控制信息的PDCCH为候选PDCCH m2时,中继UE确定该PDCCH承载的第一控制信息是调度中继UE的。
另一种可能的方案中,在某种聚合等级下所述搜索空间的一个候选PDCCH的索引用m来表示,m=0,1,…,M-1。其中,第一种情况是M为所述搜索空间中候选PDCCH的数量;或者,第二种情况是

M’为搜索空间中候选PDCCH的数量,N CCE是在一个子帧中的CCE的总数,L是聚合等级。
则承载调度远端UE的第一控制信息的候选PDCCH为满足如下公式的候选PDCCH m:
m mod 2=0(mod表示取模)
以及,承载调度中继UE的第一控制信息的候选PDCCH为满足如下公式的候选PDCCH m:
m mod 2=1
中继UE若确定承载第一控制信息的PDCCH在候选PDCCH m,且m为偶数时,中继UE确定该PDCCH承载的第一控制信息是调度远端UE的;中继UE若确定承载第一控制信息的PDCCH在候选PDCCH m,且m为奇数时,中继UE确定该PDCCH承载的第一控制信息是调度中继UE的。
可选的,承载用于调度不同设备类别的第一控制信息的候选PDCCH是由同一RNTI确定的搜索空间中的,例如,网络设备给中继UE分配的RNTI。
(5)在第五种可能的实现方案中,第一信息可以包括第一控制信息所在的子帧。第一控制信息所在的子帧可以用于确定第一控制信息用于调度第一类设备或第二类设备。
举例来说,网络设备为第一类设备和第二类设备分配不同子帧来发送第一控制信息。4个远端UE通过中继UE与网络设备通信,请参见表14,为第一控制信息所在的子帧与设备标识的映射关系。其中,第一类设备的第一控制信息是在子帧0上发送的,第二类设备的第一控制信息是在子帧1上发送的。
表14 第一控制信息所在的子帧与设备标识的映射关系
  子帧0 子帧1 子帧1 子帧1 子帧1
RNTI 0 中继UE ID 远端UE 1 ID 远端UE 2 ID 远端UE 3 ID 远端UE 4 ID
在网络设备需要发送用于调度中继UE的第一控制信息的情况下,可以在“子帧0”的位置来发送第一控制信息;同理,在网络设备需要发送用于调度远端UE 4的第一控制信息的情况下,可以在“子帧1”的位置来发送第一控制信息。这样在中继UE检测或接收到该第一控制信息的情况下,可以先确定该第一控制信息所在的子帧,进而确定第一控制信息所调度的设备分类。
表14中第二类设备的第一控制信息所在的子帧是相同的。在可选的方案中,第二类设备包含的至少一个远端UE的第一控制信息所在的子帧可以不同,且保证与第一类设备的第一控制信息所在的子帧不同。
又举例来说,传输调度中继UE的第一控制信息的子帧集合与传输调度远端UE的第一控制信息的子帧集合不重叠。比如,一部分子帧集合用于传输调度中继UE的第一控制信息,另一部分子帧集合用于传输调度远端UE的第一控制信息。
一种可能的方案中,一段时间范围内可用于传输控制信息的子帧用Si来表示,i=0,1,…,N-1,其中,N为一段时间范围内可用于传输控制信息的子帧的数量。一段时间范围内可用于传输控制信息的子帧,例如,一个无线帧中的下行子帧,或者,一个无线帧中的非上行子帧(包括下行子帧和特殊子帧)。
则用于传输承载调度远端UE的第一控制信息的PDCCH的子帧集合为Sj,j=0,1,…,J-1,其中,J<N。用于传输承载调度中继UE的第一控制信息的PDCCH的子帧集合为Sj,j=J,J+1,…,N-1。J可以在标准协议中规定,或者是网络设备配置的,或者是预配置的,或者是中继UE自己确定的。在中继UE自己确定的情况下,中继UE需要向网络设备发送指示信息,用于指示J。
可选的,对于不同的TDD UL/DL configuration,J可以是不同的。
可选的,J为N乘以一个比例因子k,0<k<=1。对于不同的TDD UL/DL configuration,该比例因子是相同的。
中继UE若确定第一控制信息在子帧Sj(j=0,1,…,J-1)中时,中继UE确定该PDCCH承载的第一控制信息是调度远端UE的。中继UE若确定第一控制信息在子帧Sj(j=J,J+1,…,N-1)中时,中继UE确定该PDCCH承载的第一控制信息是调度中继UE的。
另一种可能的方案中,一段时间范围内可用于传输控制信息的子帧用Si来表示,i=0,1,…,N-1,其中,N为一段时间范围内可用于传输控制信息的子帧的数量。一段时间范围内可用于传输控制信息的子帧,例如,一个无线帧中的下行子帧,或者,一个无线帧中的非上行子帧(包括下行子帧和特殊子帧)。
则用于传输承载调度远端UE的第一控制信息的PDCCH的子帧集合为满足如下公式的Si:
i mod 2=0(mod表示取模)
用于传输承载调度中继UE的第一控制信息的PDCCH的子帧集合为满足如下公式的Si:
i mod 2=1
中继UE若确定承载第一控制信息在子帧Si,且i为偶数时,中继UE确定该PDCCH承载的第一控制信息是调度远端UE的。中继UE若确定承载第一控制信息在子帧Si,且i为奇数时,中继UE确定该PDCCH承载的第一控制信息是调度中继UE的。
405,中继UE根据第一控制信息传输数据。
其中,在步骤403中继UE确定第一控制信息是用于调度第一类设备的情况下,由于第一类设备为中继UE,则中继UE根据第一控制信息来传输数据。举例来说,第一控制信息所包含的资源信息是用于向第一远端UE发送数据的,则中继UE在该资源信息上向该第一远端UE传输数据;或者,第一控制信息所包含的资源信息是用于接收第二远端UE发送的数据的,则中继UE在该资源信息接收第二远端UE发送的数据。其中第一远端UE或第二远端UE是至少一个远端UE中的任意一个。
可选的,在第一控制信息包含传输数据所使用的参数的情况下,中继UE根据该参数来传输数据。
可选的,在第一控制信息包含传输数据所使用的参数和资源信息的情况下,中继UE根据该参数和资源信息来传输数据。
406,中继UE确定第二信息。
其中,该步骤是可选步骤。在步骤403中继UE确定第一控制信息是用于调度第二类设备的情况下,中继UE确定第二信息,以便于确定所述第一控制信息用于调度目标远端UE,所述目标远端UE为所述第二类设备包括的至少一个第二设备中的一个。
所述第二信息包括以下至少一项:所述第一控制信息包含的第二指示信息、加扰所述第一控制信息的无线网络临时标识、所述第一控制信息的负载大小、承载所述第一控制信息的PDCCH或所述第一控制信息所在的子帧。
这里第二信息包含的每一项参数可以按照步骤402中第一信息所包含的对应参数来确定。需要说明的是,与第一信息的区别是:第二信息中所包含的参数是用于在第二类设备中确定所述第一控制信息所调度的目标远端UE,即目标远端UE是第二类设备包含的至少一个远端UE中的任意一个UE。
407,中继UE确定第一控制信息用于调度目标远端UE,所述目标远端UE为第二类设备包含的至少一个远端UE中的任意一个。
其中,在步骤403中继UE确定第一控制信息是用于调度第二类设备的情况下,中继UE根据第二信息来确定目标远端UE。
接下来对第二信息中可以包括其中几种情况进行举例说明:
(1)在第一种可能的实现方案中,第二信息包括加扰所述第一控制信息的无线网络临时标识和第一控制信息包含的第二指示信息。所述中继UE根据加扰所述第一控制信息的无线网络临时标识和所述第一控制信息包含的第二指示信息,确定所述第一控制信息用于调度目标远端UE。具体的,中继UE根据无线网络临时标识与设备之间的映射关系和第一控制信息包含的第二指示信息与设备之间的映射关系,确定与加扰所述第一控制信息的无线网络临时标识和所述第一控制信息包含的第二指示信息均对应的目标远端UE的标识,并确定所述第 一控制信息用于调度所述远端UE的标识指示的目标远端UE;其中,设备标识包括至少一个远端UE中每个远端UE的标识。
举例来说,第二类设备中每个远端UE的设备标识用identity表示,一种可能的方法是调度第二类设备的第一控制信息中包含的第二指示信息为identity mod n。加扰第一控制信息的RNTI为RNTI i
Figure PCTCN2018087215-appb-000016
RNTI i的值是网络设备配置的。其中,n可以在标准协议中规定,或者是网络设备配置的,或者是预配置的,或者是中继UE自己确定的。在中继UE自己确定的情况下,中继UE需要向网络设备发送指示信息,用于指示n。
假设:n=4。有8个远端UE通过中继UE与网络设备通信。下表15中远端UE的Identity分别为0,1,…,7。这样通过第二指示信息和RNTI可以从多个远端UE中唯一确定出一个目标远端UE。
表15 第二指示信息、RNTI、设备标识的映射关系表
  第二指示信息为0 第二指示信息为1 第二指示信息为2 第二指示信息为3
RNTI 0 Identity=0 Identity=1 Identity=2 Identity=3
RNTI 1 Identity=4 Identity=5 Identity=6 Identity=7
在网络设备需要发送用于调度远端UE identity=5的第一控制信息的情况下,可以按照该远端UE对应的“RNTI 1”来对第一控制信息进行加扰,并在第一控制信息中写入的第二指示信息为1。这样在中继UE检测或接收到该第一控制信息的情况下,可以先确定将第一控制信息接收成功的RNTI,再确定第一控制信息包含的第二指示信息,进而确定出第一控制信息所调度的目标远端UE。
另一种可能的方法是调度第二类设备的第一控制信息中包含的第二指示信息为

加扰的RNTI为RNTI i,i=identity mod n,RNTI i的值是网络设备配置的。其中,n可以在标准协议中规定,或者是网络设备配置的,或者是预配置的,或者是中继UE自己确定的。在中继UE自己确定的情况下,中继UE需要向网络设备发送指示信息,用于指示n。
假设:n=4。有8个远端UE通过中继UE与网络设备通信。下表16中有8个远端UE的Identity分别为0,1,…,7。

  第二指示信息为0 第二指示信息为1
RNTI 0 Identity=0 Identity=4
RNTI 1 Identity=1 Identity=5
RNTI 2 Identity=2 Identity=6

在本发明实施例中,对第二指示信息在第一控制信息中所占用的比特数不做限定。也不限定第二类设备对应的RNTI的数量。这里仅为举例说明,本发明实施例对这一可能的实现方案中的映射关系不做限定。
(2)在第二种可能的实现方案中,第二信息包括加扰所述第一控制信息的无线网络临时标识和所述第一控制信息所在的子帧。中继UE根据加扰所述第一控制信息的无线网络临时标识和所述第一控制信息所在的子帧,确定所述第一控制信息用于调度目标远端UE。具体的,中继UE根据无线网络临时标识与设备标识之间的映射关系和控制信息所在的子帧与设备标识之间的映射关系,确定与加扰第一控制信息的无线网络临时标识和第一控制信息所在的子帧均对应的目标远端UE的标识,并确定所述第一控制信息用于调度所述远端UE的标识指示的目标远端UE;其中,设备标识包括至少一个远端UE中每个远端UE的标识。
举例来说,第二类设备中每个远端UE的设备标识用identity表示。一段时间范围内可用于传输控制信息的子帧用Si来表示,i=0,1,…,N-1,其中,N为一段时间范围内可用于传输控制信息的子帧的数量。一段时间范围内可用于传输控制信息的子帧,例如,一个无线帧中的下行子帧,或者,一个无线帧中的非上行子帧(包括下行子帧和特殊子帧)。
一种可能的方法是第二类设备的第一控制信息所在的子帧集合为满足如下公式的Si。
Si mod n=identity mod n(mod表示取模)
加扰的RNTI为RNTI i

RNTI i的值是网络设备配置的。其中,n可以在标准协议中规定,或者是网络设备配置的,或者预配置的,或者是中继UE自己确定的。在中继UE自己确定的情况下,中继UE需要向网络设备发送指示信息,用于指示n。
可选的,对于不同的TDD UL/DL(Time Division Duplexing_Uplink/Downlink,时分双工上下行)configuration,n可以是不同的。
可选的,n为N乘以一个比例因子k,0<k<=1。对于不同的TDD UL/DL configuration,该比例因子是相同的。
假设:n=4,N=8。有8个远端UE通过中继UE与网络设备通信。下表17中远端UE的Identity分别为0,1,…,7。

可以看出,一个远端UE可以通过两类第一控制信息来调度,具体是通过加扰第一控制信息的RNTI的不同或第一控制信息所在的子帧不同来实现的。
(3)在第三种可能的实现方案中,第二信息包括第一控制信息包含的第二指示信息和所述第一控制信息所在的子帧。所述中继UE根据所述第一控制信息包含的第二指示信息和所述第一控制信息所在的子帧,确定所述第一控制信息用于调度目标远端UE。具体的,中继UE根据指示信息与设备标识之间的映射关系和控制信息所在的子帧与设备标识之间的映射关系,确定与第一控制信息的第二指示信息和第一控制信息所在的子帧均对应的目标远端UE的标识,并确定所述第一控制信息用于调度所述远端UE的标识指示的目标远端UE;其中,设备标识包括至少一个远端UE中每个远端UE的标识。
举例来说,第二类设备中每个远端UE的设备标识用identity表示。一段时间范围内可用于传输控制信息的子帧一个无线帧中的下行子帧用Si来表示,i=0,1,…,N-1,其中,N为一段 时间范围内可用于传输控制信息的子帧一个无线帧中的下行子帧的数量。一段时间范围内可用于传输控制信息的子帧,例如,一个无线帧中的下行子帧,或者,一个无线帧中的非上行子帧(包括下行子帧和特殊子帧)用Si来表示,i=0,1,…,N-1,其中,N为一个无线帧中的下行子帧和特殊子帧的数量之和。
一种可能的方法是第二类设备的第一控制信息所在的子帧集合为满足如下公式的Si。

举例来说,第二类设备中每个远端UE的设备标识用identity表示。在某种聚合等级下一个候选PDCCH的索引用m来表示,m=0,1,…,M-1,其中,M为所述搜索空间中候选PDCCH的数量。

可以看出,一个远端UE可以通过两类第一控制信息来调度,具体是通过加扰第一控制信息的RNTI的不同或第一控制信息所在的子帧不同来实现的。这里仅为举例说明,本发明实施例对这一可能的实现方案中的映射关系不做限定。
在又一种可能的实现方案中,第二信息包括第一控制信息包含的第二指示信息。所述中继UE根据所述第一控制信息包含的第二指示信息,确定所述第一控制信息用于调度目标远端UE。具体的,中继UE根据第一控制信息包含的第二指示信息与设备之间的映射关系,确定与所述第一控制信息包含的第二指示信息对应的目标设备的标识,并确定所述第一控制信息用于调度所述目标设备的标识指示的目标设备。

408,中继UE根据第一控制信息包含的用于传输数据的资源信息确定第二控制信息。
409,中继UE向目标远端UE发送第二控制信息。
410,目标远端UE根据第二控制信息传输数据。
其中,步骤408至步骤410可以参见图2所示实施例中步骤206至步骤208的详细描述,在此不再赘述。
需要说明的是,在如图2、图4所示实施例中,远端UE的设备标识identity可以为远端UE的第二标识在中继UE报告的目标列表中的索引、远端UE的本地标识(Local ID)、远端UE的邻近服务标识(ProSe UE ID)或者远端UE的层2标识(Layer-2 ID);远端UE的第二标识为远端UE的本地标识、远端UE的邻近服务标识或者远端UE的层2标识。
其中,远端UE的设备标识identity可以为远端UE的第二标识在中继UE报告的目标列表中的索引。具体的,中继UE在目标列表中指示了中继UE进行通信的一个或多个目标设备,每个目标设备通过第二标识被识别。例如,表20所示,中继UE在目标列表destinationInfoList中指示了进行侧行链路sidelink通信的一个或多个目标destination,每个目 标destination通过ProSe UE ID被识别,即该目标列表destinationInfoList中包含一个或多个ProSe UE ID,每个远端UE都有一个自己的ProSe UE ID,此时,远端UE的设备标识identity可以为远端UE的第二标识在中继UE报告的目标列表中的索引,即ProSe UE ID 5对应的远端UE的设备标识identity就为0。
表20
各远端UE的第二标识 各远端UE的设备标识identity
ProSe UE ID 5 Index 0
ProSe UE ID 3 Index 1
ProSe UE ID 4 Index 2
又一需要说明的是,图2及图4对应的方法实施例中第一控制信息是调度哪一个设备的方案是由中继UE来确定,为了描述方便,采用了第一信息与中继UE ID映射关系的描述方式,在实际中,中继UE可以不需要根据中继UE ID来确定其对应的第一信息。中继UE可以直接确定与其对应的第一信息,比如,与中继UE对应的第一信息可以是在标准协议中定义的,或者中继UE接收网络设备发送的与其对应的第一信息的指示信息。
又一需要说明的是,在本发明实施例中,中继UE可以在不执行步骤403、404、405的情况下,确定第一控制信息是用于调度至少一个远端UE中的哪个设备,具体实现过程可以参考该实施例中对应步骤的详细描述,在此不再赘述。
在本发明实施例中,中继UE在接收到网络设备发送的第一控制信息之后,能够根据与第一控制信息相关的第一信息来确定该第一控制信息是调度哪一类设备的。以及,若确定是调度包含至少一个远端UE的第二类设备的情况下,可以继续确定出该第一控制信息是用于调度至少一个远端UE中的哪一个UE的。
在另一种可能的系统架构图中,远端UE可以接收网络设备发送的第一控制信息,结合图1而言,远端UE1、远端UE2可以接收网络设备发送的控制面信令,这里的控制面信令包含本发明实施例所涉及的第一控制信息。请参见图5,为本发明实施例提供了一种控制信息的处理方法。如图5所示,在该实施例中,包括第二设备和网络设备,其中,第二设备以远端UE为例,该实施例中远端UE通过中继UE与网络设备进行通信,这里的通信是指通过中继UE向网络设备传输数据。图5中的远端UE可以确定出第一控制信息是否是调度自身设备的。
501,网络设备发送第一控制信息。
其中,第一控制信息是包含了用于传输数据的资源信息。这里的资源信息可以包括资源频域信息、资源时域信息中的至少一项。
可选的,另外一种情况下,第一控制信息包含了传输数据所使用的参数、且不包含传输数据的资源信息。又一情况下,第一控制信息包含了传输数据所使用的参数和传输数据的资源信息。其中,这里提到的传输数据所使用的参数可以包括但不限定于功率参数、调制与编码策略(Modulation and Coding Scheme,MCS)。

对于第一信息可以包括的每一项参数可以参考图2所示实施例中的详细描述,在此不再赘述。需要说明的是,图5所示实施例中第一信息可以包括的参数或参数组合并不因图2所示实施例的第一信息而受到影响。
503,所述远端UE根据第一信息确定所述第一控制信息用于调度所述远端UE。
具体的,由于第一信息包含的参数或参数组合情况较多,这里以其中几种情况为例进行举例,但未被举例说明的参数或参数组合也属于本发明实施例保护的范围。

对于第一参数为负载大小的情况,与远端UE对应的负载大小的目标值为目标负载大小;对于第一参数为承载所述第一控制信息的PDCCH的情况,与远端UE对应的承载所述第一控制信息的PDCCH的目标值为目标PDCCH;对于第一参数为第一控制信息所在的子帧的情况,与远端UE对应的第一控制信息所在的子帧的目标值为目标子帧。

(7)在第七种可能的实现方案中,第一信息包括加扰第一控制信息的无线网络临时标识和承载第一控制信息的PDCCH。远端UE根据加扰第一控制信息的无线网络临时标识和承载第一控制信息的PDCCH,确定第一控制信息用于调度远端UE。
具体实现中,远端UE确定目标无线网络临时标识和目标PDCCH集合,目标PDCCH集合包含至少一个目标PDCCH;远端UE在加扰第一控制信息的无线网络临时标识为目标无线网络临时标识,且承载第一控制信息的PDCCH属于目标PDCCH集合的情况下,确定第一控制信息用于调度远端UE。
可选的,目标无线网络临时标识和目标PDCCH集合是与远端UE相对应的与第一控制信息相关的信息,且该信息可以通过网络设备确定。
504,所述远端UE根据所述第一控制信息传输数据。
其中,在步骤503远端UE确定第一控制信息是用于调度自身设备的情况下,目标远端UE根据第一控制信息来传输数据。举例来说,第一控制信息所包含的资源信息是用于向中继UE发送数据的,则目标远端UE在该资源信息上向该中继UE传输数据;或者,第一控制信息所包含的资源信息是用于接收中继UE发送的数据的,则目标远端UE在该资源信息接收中继UE发送的数据。
可选的,在第一控制信息包含传输数据所使用的参数的情况下,远端UE根据该参数来传输数据。
可选的,在第一控制信息包含传输数据所使用的参数和资源信息的情况下,远端UE根据该参数和资源信息来传输数据。
