为了便于理解,首先介绍本公开涉及的术语。
1、下行链路控制信息(downlink control information,DCI)
下行链路控制信息(downlink control information,DCI)是调度下行链路数据信道或上行链路数据信道的特殊信息集,DCI信息包含了诸如资源块(resource block,RB)分配信息、调制与编码策略 (Modulation and Coding Scheme,MCS)等等若干相关内容。终端只有正确的解码到了DCI信息,才能正确的处理下行链路数据或上行链路数据。
2、无线网络临时标识(radio network temporary identifier,RNTI)
无线网络临时标识(radio network temporary identifier,RNTI)是终端在长期演进(long term evolution,LTE)无线网络内的唯一标识。主要有两类用途:第一用途为用于加扰下行控制信息(downlink control information,DCI),用户设备(user equipment,UE)只有使用正确的RNTI才能对接收到的消息解码。第二用途为基站用于识别UE,UE可以通过发送的无线资源控制(radio resource control,RRC)信息,传输自己专用的RNTI值。
3、智能中继(smart repeater)
智能中继,可以为任意一种至少能定向放大信号的网络设备,或者,具有定向放大信号功能的终端设备。
4、智能超表面(reconfigurable intelligence surface,RIS)
智能超表面RIS,也被称为“可重构智能表面”或者“智能反射表面”。从外表上看,RIS是一张平平无奇的薄板。但是,它可以灵活部署在无线通信传播环境中,并实现对反射或者折射电磁波的频率、相位、极化等特征的操控,从而达到重塑无线信道的目的。具体地说,RIS可以通过预编码技术,将入射到其表面的信号反射到特定的方向,从而增强接收端信号强度,实现对信道的控制。
由于smart repeater和RIS在网络交互时具有类似的特性,因此,本公开中,智能中继,代指smart repeater和RIS。
为了更好的理解本公开实施例公开的一种智能中继的波束指示方法,下面首先对本公开实施例适用的通信***进行描述。
请参见图1,图1为本公开实施例提供的一种通信***的架构示意图。该通信***可包括但不限于一个网络设备、一个智能中继和一个终端设备,图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定,实际应用中可以包括两个或两个以上的网络设备,两个或两个以上的智能中继,两个或两个以上的终端设备。图1所示的通信***以包括一个网络设备11、一个终端设备12和一个智能中继13为例。
需要说明的是,本公开实施例的技术方案可以应用于各种通信***。例如:长期演进(long term evolution,LTE)***、第五代(5th generation,5G)移动通信***、5G新空口(new radio,NR)***,或者其他未来的新型移动通信***等。
本公开实施例中的网络设备11是网络侧的一种用于发射或接收信号的实体。例如,网络设备101可以为演进型基站(evolved NodeB,eNB)、传输点(transmission reception point,TRP)、NR***中的下一代基站(next generation NodeB,gNB)、其他未来移动通信***中的基站或无线保真(wireless fidelity,WiFi)***中的接入节点等。本公开的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本公开实施例提供的网络设备可以是由集中单元(central unit,CU)与分布式单元(distributed unit,DU)组成的,其中,CU也可以称为控制单元(control unit),采用CU-DU的结构可以将网络设备,例如基站的协议层拆分开,部分协议层的功能放在CU集中控制,剩下部分或全部协议层的功能分布在DU中,由CU集中控制DU。
本公开实施例中的终端设备12是用户侧的一种用于接收或发射信号的实体,如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment,UE)、移动台(mobile station,MS)、移动终端设备(mobile terminal,MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本公开的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
本公开实施例中的智能中继13可以为任意一种至少能定向放大信号的网络设备。
可以理解的是,本公开实施例描述的通信***是为了更加清楚的说明本公开实施例的技术方案,并不构成对于本公开实施例提供的技术方案的限定,本领域普通技术人员可知,随着***架构的演变和新业务场景的出现,本公开实施例提供的技术方案对于类似的技术问题,同样适用。
通常,智能中继需要负责两条链路,即服务链路(service link)和馈线链路(feeder link)。因此,需要设计新的DCI格式来支持基站向智能中继移动终端指示波束信息,以完成智能中继和终端设备之间服务链路的波束管理,及智能中继和基站之间的馈线链路的波束管理。下面结合附图对本公开所提供的一种智能中继的波束指示方法及其装置进行详细地介绍。
请参见图2,图2是本公开实施例提供的一种智能中继的波束指示方法的流程示意图,该方法由网络设备执行。如图2所示,该方法可以包括但不限于如下步骤:
步骤201,通过预设的无线网络临时标识RNTI对下行控制信息DCI进行加扰,其中,DCI至少用于指示智能中继待使用的波束的信息。
其中,预设的RNTI,可以为任一约定的用于为智能中继进行波束指示时的加扰方式。比如可以为新的RNTI类型,或者,也可以为复用的已有的RNTI类型,本公开对此不做限定。
另外,智能中继待使用的波束可以为反馈链路对应的波束,或者服务链路对应的波束等。
可选的,波束的信息可以包括:波束的标识(identification,ID),波束的使用时间信息,波束对应的链路,及波束配置的标识等,本公开对此不做限定。
其中,波束的标识可以为任一可以唯一确定波束的信息,其可以为TCI标识,或者参考信号标识等。比如,波束ID,可以通过参考信号来指示,以在DCI中进行波束指示为例,可以在DCI里包含一个参考信号ID用以表示一个波束ID,参考信号ID可以是信道状态信息参考信号资源指示CRI(CSI-RS resource indicator),探测信号资源指示SRI(SRS-resource indicator)或者同步信号块序号SSBI(SS block index)。或者,可以把参考信号ID配置在TCI中,DCI中包含该TCI,TCI中D类准共址(quasico-location,QCL)参数qcl-type-D对应的参考信号ID表示波束ID。上述参考信号可以是RRC配置的一个周期性参考信号,非周期性参考信号或者半静态参考信号。本公开对此不做限定。以下提到的波束ID皆可用本段提到的参考信号来指示,因此提到波束ID时可以等同于CRI或者SRI或者TCI等,以下描述均使用波束ID。
另外,波束的使用时间信息为以下至少一项:波束的起始位置,波束的使用时长以及波束对应的时域调度表格的序号。
其中,波束的起始位置及使用时长等,可以通过时间单元指示,比如,波束的起始位置为接收到DCI指示后的第x个时间单元,或者波束的使用时长为Y个时间单元等等,本公开对此不做限定。其中,时间单元,可以为时隙,微时隙,符号等等,其可以是网络设备指示的也可以是通过协议约定的,本公开对此不做限定。
可选的,波束对应的链路用于指示使用该波束的链路。波束对应的链路,可以通过不同的DCI加扰方式指示,或者也可以在DCI中引入新的比特bit来指示。
比如,DCI通过小区RNTI(C-RNTI)加扰,则表示该DCI指示的波束对应的链路为反馈链路,DCI通过预设的智能中继(SR-RNTI)加扰,则表示该DCI指示的波束对应的链路为服务链路等等。
或者,DCI中新引入的bit取值为1时,表示波束对应的链路为反馈链路,取值为0时,表示对应的链路为服务链路;或者,新引入的bit取值为0时,表示波束对应的链路为服务链路,取值为1时,表示对应的链路为反馈链路,等等,本公开对此不做限定。
其中,波束配置的标识,为网络设备通过RRC向智能中继进行波束配置时的标识。一个波束配置的标识可以对应以下参数组中的一个或多个:一组波束标识、波束循环周期、波束的的起始位置;或者,一个波束标识、波束循环周期、波束的的起始位置;或者,一组波束标识、波束循环周期;或者,一个波束标识、波束循环周期;或者,一组波束标识。从而,DCI通过指示一个波束配置的标识,即可指示以上各组参数中的一个或多个。
步骤202,向智能中继发送加扰后的DCI。本公开中,网络设备向智能中继发送加扰后的DCI后,智能中继可以通过监听信道,并利用相应的RNTI,对DCI进行解码,获取智能中继待使用的波束的信息,并按照波束的信息,在相应的链路上,进行信号的接收和发送。
本公开中,网络设备通过预设的无线网络临时标识RNTI对用于指示智能中继待使用的波束的DCI进行加扰,之后再向智能中继发送加扰后的DCI。由此,通过采用智能中继已知的预设的RNTI对DCI进行加扰来向智能中继进行波束指示,实现智能中继对不同链路的波束的有效管理,保证了智能中继的可靠使用,为扩大服务小区覆盖范围提供了条件。
请参见图3,图3是本公开实施例提供的另一种智能中继的波束指示方法流程示意图。如图3所示,该方法可以由网络设备执行,该方法可以包括但不限于如下步骤:
步骤301,发送无线资源控制RRC消息,其中,RRC中包含至少一个时域调度表格。
其中,时域调度表格中,可以包含很多行,每一行包括一个波束或者一组波束对应的起始时间和持续时长,及对应的索引序号等。本公开对此不作限制。
本公开中,网络设备可以在RRC参数中配置一个或多个时域调度表格,然后,将此RRC消息发送给智能中继。
步骤302,通过预设的无线网络临时标识RNTI对下行控制信息DCI进行加扰,其中,DCI用于指示智能中继待使用的波束的信息。
其中,上述步骤302的具体实现形式,可参照本公开任一实施例的详细描述,此处不再赘述。
需要说明的是,由于网络设备已经通过RRC消息配置了时域调度表格,因此,网络设备可以通过DCI指示与波束的使用时间信息对应的时域调度表格的序号的形式,来向智能中继指示波束的使用时间信息。
比如,网络设备可以将时域调度表格中的某一索引序号,配置在DCI中。智能中继在接受到RRC信息及DCI信息后,即可根据DCI信息中的索引序号,从RRC信息所携带的时域调度表格中,查询并获取波束对应的使用时间信息。
可选的,若网络设备通过RRC消息配置了多个时域调度表格,则网络设备还可以将任一时域调度表格名称及其包含的任一索引序号,配置在DCI中。智能中继在接收到包含此时域调度表格的RRC信息及DCI信息后,即可根据DCI信息中的表格名称,在RRC信息中,确定对应的时域调度表格,并根据DCI信息中的索引序号和此时域调度表格,确定波束对应的使用时间信息。
或者,网络设备还可以在DCI中直接指示波束的使用时间信息。比如,网络设备可以将波束的起始位置及波束的使用时长信息,按照任一固定格式,直接配置在DCI信息中。其中,固定格式可以为:任一波束ID,和其对应的波束的起始位置,及波束的使用时长信息组合等。本公开对此不作限制。当智能中继接收到直用于接指示波束的DCI信息后,即可确定待使用波束ID,并根据任一波束ID与和其对应的波束的起始位置,及波束的使用时长信息组合关系,即可确定任一波束的使用时间信息。
步骤303,向智能中继发送加扰后的DCI。
本实施例中,步骤303的具体实现过程,可参见本公开任一实施例的详细描述,在此不再赘述。
本公开中,网络设备可以在向智能中继发送包含至少一个时域调度表格的无线资源控制RRC消息后,通过预设的无线网络临时标识RNTI对用于指示智能中继待使用的波束的DCI进行加扰,然后再向智能中继发送加扰后的DCI。由此,通过采用智能中继已知的预设的RNTI对DCI进行加扰来向智能中继进行波束指示,实现智能中继对不同链路的波束的有效管理,保证了智能中继的可靠使用,为扩大服务小区覆盖范围提供了条件。
请参见图4,图4是本公开实施例提供的另一种智能中继的波束指示方法流程示意图。如图4所示,该方法可以由网络设备执行,该方法可以包括但不限于如下步骤:
步骤401,根据待使用的波束对应的链路,确定DCI中预设比特的取值。
本公开中,可以用DCI中任一比特位,指示波束所对应的链路。比如,当使用DCI中1bit指示波束对应的链路时,如果波束对应的链路为服务链路,可以确定此比特值为0,如果波束对应的链路为反馈链路,可以确定此比特值为1;或者,如果波束对应的链路为服务链路,可以确定此比特值为1,如果波束对应的链路为反馈链路,可以确定此比特值为0,等等,本公开对此不做限定。
可选的,还可以根据波束对应的链路类型,确定其对应的加扰方式。比如,在待使用的波束对应的链路为反馈链路的情况下,可以确定加扰方式为小区无线网络临时标识C-RNTI,在待使用的波束对应的链路为服务链路的情况下,可以确定加扰方式为智能中继关联的RNTI。之后,网络设备即可利用相应的RNTI,对DCI进行加扰。由此,智能中继即可利用相应的RNTI解码DCI信息,获取相应链路的波束指示信息。
步骤402,通过预设的无线网络临时标识RNTI对下行控制信息DCI进行加扰,其中,DCI至少用于指示智能中继待使用的波束的信息。
其中,上述步骤402的具体实现形式,可参照本公开任一实施例的详细描述,此处不再赘述。
可选的,DCI中还包含用于指示智能中继待使用的波束的频域信息。其中,波束的频域信息,用于指示使用该波束的频域。由此,智能中继即在波束的频域信息指示的频域内,使用该波束。比如,智能中继收到的DCI中指示了一个频域ID,智能中继将信号搬移到该频域ID指示的频率位置上,并使用DCI中指示的波束ID进行收发。
步骤403,向智能中继发送加扰后的DCI。
本实施例中,步骤403的具体实现过程,可参见本公开任一实施例的详细描述,在此不再赘述。
本公开中,网络设备在根据待使用的波束对应的链路,确定DCI中预设比特的取值后,通过预设的无线网络临时标识RNTI对用于指示智能中继待使用的波束的DCI进行加扰,然后再向智能中继发送加扰后的DCI。由此,通过采用智能中继已知的预设的RNTI对DCI进行加扰来向智能中继进行波束指示,实现智能中继对不同链路的波束的有效管理,保证了智能中继的可靠使用,为扩大服务小区覆盖范围提供了条件。
请参见图5,图5是本公开实施例提供的另一种智能中继的波束指示方法流程示意图。如图5所示,该方法可以由智能中继执行,该方法可以包括但不限于如下步骤:
步骤501,接收由预设的无线网络临时标识RNTI加扰后的下行控制信息DCI,其中,DCI至少用于指示智能中继待使用的波束的信息。
其中,预设的RNTI,可以为任一约定的用于为智能中继进行波束指示时的加扰方式。比如可以为新的RNTI类型,或者,也可以为复用的已有的RNTI类型,本公开对此不做限定。
另外,智能中继待使用的波束可以为反馈链路对应的波束,或者服务链路对应的波束等。
可选的,波束的信息可以包括:波束的标识(identification,ID),波束的使用时间信息,波束对应的链路,及波束配置的标识等,本公开对此不做限定。
其中,波束的标识可以为任一可以唯一确定波束的信息,其可以为TCI标识,或者参考信号标识等。比如,波束ID,可以通过参考信号来指示,以在DCI中进行波束指示为例,可以在DCI里包含一个参考信号ID用以表示一个波束ID,参考信号ID可以是信道状态信息参考信号资源标识CRI(CSI-RS resource ID),探测信号资源标识SRI(SRS-resource ID)或者同步信号块序号SSBI(SS block index)。或者,可以把参考信号ID配置在TCI中,DCI中包含该TCI,TCI中D类准共址(quasico-location,QCL)参数qcl-type-D对应的参考信号ID表示波束ID。上述参考信号可以是RRC配置的一个周期性参考信号,非周期性参考信号或者半静态参考信号。本公开对此不做限定。
另外,波束的使用时间信息为以下至少一项:波束的起始位置,波束的使用时长以及波束对应的时域调度表格的序号。
其中,波束的起始位置及使用时长等,可以通过时间单元指示,比如,波束的起始位置为接收到DCI指示后的第x个时间单元,或者波束的使用时长为Y个时间单元等等,本公开对此不做限定。其中,时间单元,可以为时隙,微时隙,符号等等,其可以是网络设备指示的也可以是通过协议约定的,本公开对此不做限定。
可选的,波束对应的链路用于指示使用该波束的链路。波束对应的链路,可以通过不同的DCI加扰方式指示,或者也可以在DCI中引入新的比特bit来指示。
比如,DCI通过小区RNTI(C-RNTI)加扰,则表示该DCI指示的波束对应的链路为反馈链路,DCI通过预设的智能中继(SR-RNTI)加扰,则表示该DCI指示的波束对应的链路为服务链路等等。
或者,DCI中新引入的bit取值为1时,表示波束对应的链路为反馈链路,取值为0时,表示对应的链路为服务链路;或者,新引入的bit取值为0时,表示波束对应的链路为服务链路,取值为1时,表示对应的链路为反馈链路,等等,本公开对此不做限定。
其中,波束配置的标识,为网络设备通过RRC向智能中继进行波束配置时的标识。一个波束配置的标识可以对应以下参数组中的一个或多个:一组波束标识、波束循环周期、波束的的起始位置;或者,一个波束标识、波束循环周期、波束的的起始位置;或者,一组波束标识、波束循环周期;或者,一个波束标识、波束循环周期;或者,一组波束标识。从而,DCI通过指示一个波束配置的标识,即可指示以上各组参数中的一个或多个。
本公开中,网络设备向智能中继发送加扰后的DCI后,智能中继可以通过监听信道,并利用相应的RNTI,对DCI进行解码,获取智能中继待使用的波束的信息,并按照波束的信息,在相应的链路上,进行信号的接收和发送。
本公开中,智能中继通过接收网络设备发送的,由预设的无线网络临时标识RNTI加扰后的下行控制信息DCI,其中,DCI至少用于指示智能中继待使用的波束的信息。由此,通过采用智能中继已知的预设的RNTI对DCI进行加扰来向智能中继进行波束指示,实现智能中继对不同链路的波束的有效管理,保证了智能中继的可靠使用,为扩大服务小区覆盖范围提供了条件。
请参见图6,图6是本公开实施例提供的另一种智能中继的波束指示方法流程示意图。如图6所示, 该方法可以由智能中继执行,该方法可以包括但不限于如下步骤:
步骤601,接收无线资源控制RRC消息,其中,RRC中包含至少一个时域调度表格。
其中,时域调度表格中,可以包含很多行,每一行包括一个波束或者一组波束对应的起始时间和持续时长,及对应的索引序号等。本公开对此不作限制。
本公开中,网络设备可以在RRC参数中配置一个或多个时域调度表格,然后,将此RRC消息发送给智能中继。智能中继可以通过监听信道,接收网络设备发送的无线资源控制RRC消息。
步骤602,接收由预设的无线网络临时标识RNTI加扰后的下行控制信息DCI,其中,DCI至少用于指示智能中继待使用的波束的信息。
其中,上述步骤602的具体实现形式,可参照本公开任一实施例的详细描述,此处不再赘述。
需要说明的是,由于智能中继已经接收网络设备发送的包含时域调度表格的RRC消息,因此,可以通过DCI中指示与波束的使用时间信息对应的时域调度表格的序号,确定波束的使用时间信息。
比如,网络设备可以将时域调度表格中的某一索引序号,配置在DCI中。智能中继在接受到RRC信息及DCI信息后,即可根据DCI信息中的索引序号,从RRC信息所携带的时域调度表格中,查询并获取波束对应的使用时间信息。
可选的,若网络设备通过RRC消息配置了多个时域调度表格,则网络设备还可以将任一时域调度表格名称及其包含的任一索引序号,配置在DCI中。智能中继在接收到包含此时域调度表格的RRC信息及DCI信息后,即可根据DCI信息中的表格名称,在RRC信息中,确定对应的时域调度表格,并根据DCI信息中的索引序号和此时域调度表格,确定波束对应的使用时间信息。
或者,网络设备还可以在DCI中直接指示波束的使用时间信息。比如,网络设备可以将波束的起始位置及波束的使用时长信息,按照任一固定格式,直接配置在DCI信息中。其中,固定格式可以为:任一波束ID,和其对应的波束的起始位置,及波束的使用时长信息组合等。本公开对此不作限制。当智能中继接收到直用于接指示波束的DCI信息后,即可确定待使用波束ID,并根据任一波束ID与和其对应的波束的起始位置,及波束的使用时长信息组合关系,即可确定任一波束的使用时间信息。
可选的,DCI中还可以包含波束对应的链路用于指示使用该波束的链路。波束对应的链路,可以通过不同的DCI加扰方式指示,或者也可以在DCI中引入新的比特bit来指示。
本公开中,智能中继可以在接收网络设备发送的包含至少一个时域调度表格的无线资源控制RRC消息后,再接收由预设的无线网络临时标识RNTI加扰后的下行控制信息DCI。由此,通过采用智能中继已知的预设的RNTI对DCI进行加扰来向智能中继进行波束指示,实现智能中继对不同链路的波束的有效管理,保证了智能中继的可靠使用,为扩大服务小区覆盖范围提供了条件。
请参见图7,图7是本公开实施例提供的另一种智能中继的波束指示方法流程示意图。如图7所示,该方法可以由智能中继执行,该方法可以包括但不限于如下步骤:
步骤701,接收由预设的无线网络临时标识RNTI加扰后的下行控制信息DCI,其中,DCI至少用于指示智能中继待使用的波束的信息。
其中,上述步骤701的具体实现形式,可参照本公开任一实施例的详细描述,此处不再赘述。
可选的,DCI中还包含用于指示智能中继待使用的波束的频域信息。其中,波束的频域信息,用于指示使用该波束的频域。由此,智能中继即在波束的频域信息指示的频域内,使用该波束。比如,智能中继收到的DCI中指示了一个频域ID,智能中继将信号搬移到该频域ID指示的频率位置上,并使用DCI中指示的波束ID进行收发。
步骤702,根据无线网络临时标识RNTI和\或DCI中预设比特的取值,确定待使用的波束对应的链路。
本公开中,智能中继在接收到DCI后,可以根据DCI中预设比特的取值,确定待使用的波束对应的链路。比如,在预设比特的取值为第一数值的情况下,确定待使用的波束对应的链路为反馈链路;在预设比特的取值为第二数值的情况下,确定待使用的波束对应的链路为服务链路。其中,第一数值可以为预设的与反馈链路对应的数值,第二数值可以为预设的与服务链路对应的数值,第一数值和第二数值可以分别为0和1,或者1和0,本公开对此不作限制。
可选的,还可以根据DCI的加扰方式,确定待使用的波束对应的链路。比如,在DCI为由预设的RNTI加扰的情况下,可以确定待使用的波束对应的链路为服务链路,或者,在DCI为由小区C-RNTI加扰的情况下,确定待使用的波束对应的链路为反馈链路。
本公开中,智能中继在接收网络设备发送的由预设的无线网络临时标识RNTI加扰后的下行控制信 息DCI后,再根据DCI中预设比特的取值,确定待使用的波束对应的链路。由此,通过采用智能中继已知的预设的RNTI对DCI进行加扰来向智能中继进行波束指示,实现智能中继对不同链路的波束的有效管理,保证了智能中继的可靠使用,为扩大服务小区覆盖范围提供了条件。
下面结合不同的应用场景,对本公开中的智能中继的波束指示方法中DCI指示的波束的信息的具体内容,进行进一步说明。
举例来说,在动态调度业务,智能中继需要在一个持续时段内使用某个特定的波束,此时,网络设备向智能中继发送的DCI中指示的波束信息,可以包括一个波束ID、波束的使用时间信息等。可以理解的是,DCI中指示的波束的使用时间信息,可以是具体的波束的起始位置,或者还可以为一个时域调度表格的序号,其中,该时域调度表格的序号对应RRC配置的时域调度表格中的一个时间信息。
或者,在动态调度业务,网络设备向智能中继发送的DCI中指示的波束信息也可以为一个波束配置ID,该波束配置ID对应一个RRC配置的一个波束ID和波束的使用时间信息等等,本公开对此不做限定。
另外,在半静态调度业务的场景下,智能中继需要在一段时间内以一定的周期使用某个波束,此时,网络设备向智能中继发送的DCI中指示的波束信息,可以包括一个波束配置ID,其中,该波束配置ID可以对应一个RRC配置的半静态的波束ID及该波束的使用周期。
或者,在半静态调度业务的场景下,网络设备向智能中继发送的DCI中指示的波束信息中,也可以包括一个半静态的波束ID及该半静态的波束ID的使用时间信息等等。可以理解的是,DCI中指示的波束的使用时间信息,可以是具体的波束的起始位置,或者还可以为一个时域调度表格的序号,其中,该时域调度表格的序号对应RRC配置的时域调度表格中的一个时间信息。
再者,在波束循环场景中,网络设备通过DCI指示的波束用于波束扫描,DCI中指示的波束的信息,可以包括波束的ID,可选的,还可以包括波束的重复使用次数。此时,波束的ID,可以为波束配置的标识,或者一组波束的标识,或者一个波束的标识等等。其中,波束配置的标识,可以对应一个RRC配置的非周期的波束ID集合,或者,该波束配置ID可以对应一个RRC配置的半静态的波束ID集合。本公开对此不做限定。另外,波束的重复使用次数可以由波束的时间信息隐性的指示,比如智能中继在时域调度表格序号指示的时间内重复发送该波束。
举例来说,比如终端设备选择智能中继侧波束时,DCI中指示的为一组波束的ID。智能中继可以通过依次或循环发送该一组波束ID分别对应的多个波束,支持终端设备选择一个智能中继通信质量较好的波束。比如,智能中继设备接收到网络设备发送的包含波束配置的标识的DCI后,即可根据波束配置的标识,确定待使用的波束列表,然后按照波束列表再向终端设备循环发送波束。终端设备即可分别对波束列表中各个波束进行检测,以选择一个通信能力较好的波束。其中,发送波束的顺序可以和RRC配置中的波束顺序一致,智能中继在每个时间单元切换波束,时间单元可以是slot,本专利对时间单元的颗粒度不做限制。
又如,DCI中指示的为一个波束的ID,智能中继可以通过重复发送该一个波束ID对应的波束,支持终端设备选择一个自身通信质量较好的波束。比如,在确定智能中继通信能力较好的波束之后,网络设备即可将DCI中的波束配置的标识,配置为只包含此波束的非周期的参考信号集合的ID。或者,在确定智能中继能力较好的波束之后,网络设备即可将DCI中的波束信息确定为该波束ID及其时间信息。智能中继在接收到此DCI信息后,即可向终端设备循环发送此波束。终端设备在智能中继通信能力较好的波束基础上,可以将检测波束分成多个窄的检测波束。然后终端设备可以分别使用每个窄的检测波束,分时与智能中继使用的波束进行通信,以检测每个窄的检测波束所对应的通信能力,从而可以将通信能力较好的窄的检测波束,确定为自身通信能力较好的波束。
下面对智能中继的波束指示方法作进一步说明,本公开中,网络设备可通过以下过程实现智能中继的波束指示:
首先,网络设备通过预设的RNTI加扰DCI后,将此DCI发送给智能中继设备。其中,DCI的类型可以为2-x。智能中继或者具有智能中继功能的终端设备可以监听通过预设的RNTI加扰DCI,在收到该DCI后,即可将该DCI中的待使用的波束的信息应用在反馈链路和/或服务链路上。
可选的,该DCI可以位于终端设备的特殊搜索空间(specific search space)内,即中继设备或者具有智能中继功能的终端设备在终端设备的特殊搜索空间中盲检该DCI。或者,该DCI还可以位于公共搜索空间内,本公开对此不做限定。
具体的,DCI至少要支持动态调度时波束指示的功能,而针对动态调度业务,至少需要波束信息和 波束使用时间信息。具体可通过以下方式实现:
方式一,使用时间信息可以在DCI中指示,比如起始位置,使用的时间长度等时间信息可以在DCI中指示。DCI中至少包含以下项:
1、波束的标识
可以针对一组波束(一个对应于服务链路,一个对应于反馈链路)。
可以分别针对服务链路或者反馈链路,此时可以在DCI中可以新引入1bit来指示是针对反馈链路的还是反馈链路;或者通过RNTI区分,C-RNTI指示反馈链路,预设的RNTI指示服务链路。
2、波束的起始位置和/或波束的使用时长,智能中继在收到该DCI的波束的起始位置所指示的时间单位后开始使用指示的波束,使用时长为波束的使用时长所指示的时间单位。时间单位可以是时隙(slot)或者符号(symbol)。
方式二,可以在RRC参数配置上行和/或下行时域调度表格,比如RRC定义一个时域调度表格,比如开始和持续时间表格(start symbol and the number of consecutive symbols for PDSCH,SLIV),SLIV表格的索引序号可以放在DCI中于波束一起指示,表示波束的使用时间(起始时间,时间长度)。DCI中至少包含以下项:
1、波束的标识
可以针对一组波束(一个对应于服务链路,一个对应于反馈链路)。
可以分别针对服务链路或者反馈链路,此时可以在DCI中可以新引入1bit来指示是针对反馈链路的还是反馈链路;或者通过RNTI区分,C-RNTI指示反馈链路,预设的RNTI指示服务链路。
2、时域调度表格的索引序号
本公开中,DCI还可以支持触发非周期波束的功能。
可选的,在一组波束循环发送,用以支持终端设备选择智能中继的波束场景中,DCI中至少包含以下项:
方式一,DCI中指示波束配置的标识,其中该波束配置可以由RRC配置的,且包含多个波束标识,
方式二,DCI中指示多个波束ID。
在一组波束循环发送,用以支持终端设备选择智能中继的波束场景中,可以优先选择方式一的波束指示方式。
可选的,在一个波束重复发送,用以支持终端设备选择自己的波束场景中,DCI中至少包含以下项:
方式一,DCI中指示波束配置的标识,其中该波束配置可以由RRC配置的,其中仅包含一个波束标识,以及该波束重复发送的次数。
方式二:DCI中直接指示该波束ID,以及该波束的重复发送次数。
在一个波束重复发送,用以支持终端设备选择自己的波束场景中,可以优先选择方式二的波束指示方式。
以上,当智能中继收到波束ID时,按照波束ID顺序使用这些波束,波束使用粒度默认是一个时间单元,比如一个slot/symbol,或者基站指示的其他时间单元。
