Description

波束失败报告发送方法、接收方法、用户设备和网络设备
本申请要求2017年06月9日提交中国专利局、申请号为201710434526.4、发明名称为“一种传输波束失败恢复请求信息的方法及设备”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文件中。仅仅是为了简洁表述,其全部内容不在本申请文件中再原文重复一遍。
技术领域
本发明实施例涉及通信领域,尤其涉及一种波束失败报告发送方法、接收方法、用户设备和网络设备。
背景技术
第五代(5th Generation,5G)移动通信技术(mobile communication technology)是对第四代(the 4Generation,4G)移动通讯技术的延伸。因此,5G通信系统被称为“超4G网络”或“后LTE(Long Term Evolution,长期演进)系统”或者新空口(New Radio,NR)。
5G通信系统中的网络设备(例如,下一代基站(Next Generation Node B,gNB)发送和接收点(Transmission and Reception Point,TRP))可以通过波束成形(Beamforming)技术与用户设备(User Equipment,UE)进行交互。网络设备通常可以形成多个下行链路传输波束(Downlink Transmission Beam或者Downlink transmitting beam,DL Tx Beam),在某一个或者多个DL Tx Beam上向每个DL Tx Beam覆盖范围内的UE发送下行信号。UE可以通过接收波束(Receiving Beam或Rx Reception beam,Rx Beam)或者全向天线进行接收,以获得较大的阵列增益。但是,由于Beamforming技术要求网络设备与UE之间具有关于方向性的要求(如,UE需要在网络设备的下行链路传输波束的覆盖范围内),当UE移动,或者UE与网络设备之间的传输链路遭到遮挡时,会导致UE和网络设备之间原来的DL Tx Beam上的下行链路传输质量下降,当下行链路传输质量下降到某个阈值时,可能会发生下行链路传输波束失败(Downlink Beam Failure,DL Beam Failure)。
因此,UE需要向网络设备上报发生了DL Beam Failure,以便于网络设备重新选择DL Tx Beam。
现有技术方案中,通常UE使用物理随机接入信道(Physical Random Access Channel,PRACH)上报DL Beam Failure,这样需要定义专用的前导码(Preamble)序列(前导码序列通常会占用较多的资源)用于指示下行链路传输波束失败,通过在物理随机接入信道上定义专用的前导码序列会增加额外的资源开销。
发明内容
本发明实施例提供一种波束失败报告发送方法、接收方法、用户设备和网络设备,用以通过较小的资源开销实现UE向网络设备上报进行下行链路传输的下行链路波束发生失败。
第一方面,本发明实施例提供一种波束失败报告发送方法,包括:生成包括第一指示信息和候选波束信息的波束失败报告,候选波束信息用于向网络设备指示UE确定的一个或多个候选下行链路传输波束,UE在物理上行链路控制信道(Physical Uplink Control Channel,PUCCH)的第一资源上向网络设备发送波束失败报告,第一指示信息用于向网络设备指示UE在第一资源上传输的内容为波束失败报告,第一资源用于用户设备发送信道状态信息CSI(Channel State Information)报告和/或波束信息报告(Beam Reporting)。
本发明实施例提供一种波束失败报告发送方法,UE在确定网络设备进行下行链路传输的下行链路传输波束上发生下行链路波束失败之后,通过在物理上行链路控制信道的第一资源上向网络设备发送包括第一指示信息以及候选波束信息的波束失败报告,由于第一资源不仅可以用于发送波束失败报告,还可以用于用户设备发送信道状态信息报告和波束信息报告中的一项或多项,这样在物理上行链路控制信道上的资源有限的情况下,可以将UE用于发送波束失败报告的第一资源与信道状态信息报告和/或波束信息报告共享(也可称之为共享),以实现在第一资源的不同时刻实现在第一资源上发送不同报告的用途,使得发送波束失败报告不再占用物理上行链路控制信道的其他资源,从而通过较小的资源开销实现UE向网络设备上报进行下行链路传输的下行链路波束发生失败,且可以使UE使用更多的物理上行链路控制信道上的其他资源向网络设备传输数据。
结合第一方面,在第一方面的第一种可能的实现方式中,用户设备UE生成波束失败报告之前,本发明实施例提供的方法还包括:UE在检测到网络设备进行下行链路传输的下行链路传输波束发生波束失败的情况下,UE获取网络设备在一个或多个下行链路传输波束中每个下行链路传输波束发送的参考信号的参数;UE根据获取到的每个下行链路传输波束发送的参考信号的参数,将获取到的参考信号的参数中满足第一预设条件的参考信号所在的下行链路传输波束中的一个或多个确定为候选下行链路传输波束。通过UE确定并向网络设备发送候选波束信息,这样便于网络设备确定下一次向用户设备进行下行链路传输时的下行链路传输波束。
结合第一方面或第一方面的第一种可能的实现方式,在第一方面的第二种可能的实现方式中,本发明实施例提供的方法还包括:UE根据获取到的参考信号的参数中满足第一预设条件的参考信号所在的接收波束,确定与一个或多个候选下行链路传输波束中每个下行链路传输波束对应的接收波束。通过确定与候选下行链路传输波束中每个下行链路传输波束对应的接收波束,这样UE可以通过与每个下行链路传输波束对应的接收波束来接收网络设备发送的下行链路传输信息。
结合第一方面至第一方面的第二种可能的实现方式中任一项,在第一方面的第三种可能的实现方式中,用户设备UE生成波束失败报告之前,本发明实施例提供的方法还包括:UE周期性的获取网络设备在一个或多个下行链路传输波束中每个下行链路传输波束发送的参考信号的参数;UE根据每个周期获取到的参考信号的参数,在UE检测到下行链路波束失败后,将最近一个周期获取到的参考信号的参数中满足第一预设条件的参考信号所在的下行链路传输波束中的一个或多个确定为候选下行链路传输波束。通过利用发生波束失败之前最近一个周期获取到的参考 信号的参数中满足第一预设条件的参考信号所在的下行链路传输波束确定候选下行链路传输波束,这样在波束失败后可以避免需要测量参考信号参数来确定候选下行链路传输波束造成的时延。

具体实施方式
传统技术方案中,通常UE使用物理随机接入信道上报DL Beam Failure,这样需要定义专用的前导码(Preamble)序列用于指示波束失败,增加了标准化的工作量,且通过在物理随机接入信道上定义专用的前导码会增加了额外的开销。本申请UE在确定进行下行链路传输的波束上发生波束失败之后,通过在物理上行链路控制信道的第一资源上向网络设备发送包括第一指示信息以及候选波束信息的波束失败报告,由于第一资源不仅可以用于发送波束失败报告,还可以用于用户设备进行信道状态信息报告和波束信息报告中的一项或多项,由于物理上行链路控制信道上的资源是有限的,通过将UE发送波束失败报告的第一资源与信道状态信息报告和/或波束信息报告共享,可以在物理上行链路控制信道上减少额外的开销,且可以使UE使用更多的资源向网络设备传输数据。
图1和图2示出的是可以应用本申请实施例的系统架构的简化示意图。
本发明实施例提供的方法可以应用于无线通信系统的场景中,例如新空口(New Radio,NR)场景、LTE下一代场景、无线局域网(Wireless Local Area Networks,WLAN)场景、蓝牙通信等场景中。为描述方便,本发明实施例以新空 口场景为例进行说明。
如图1所示,在本申请实施例的第一种应用场景下,在NR场景下,该系统架构可以包括:新空口的核心网10,例如,新空口新无线接入技术核心网(New Radio new redio access technology core,NR_newRAT-Core)以及新空口的接入网20。
其中,新空口的接入网20中的功能实体可以为网络设备30,及与新空口的接入网20中的网络设备30连接的一个或多个UE,如图1所示的用户设备40和用户设备70,具体的,用户设备40和用户设备70分别通过链路1与网络设备30连接。
其中,网络设备30具体可以为gNB、新型无线电基站(New radio eNB)、传输点(transmission and reception point,TRP)、宏基站、微基站、高频基站、LTE宏或微eNB、CPE、WLAN接入点(Access Point,AP)、WLAN组所有者(Group owner,GO)等中的任一种或者多种组合。例如,网络设备30可以为一个gNB,由该gNB完成本发明实施例中网络设备所涉及的功能,或者,网络设备30为gNB与TRP的组合,如由gNB完成本发明实施例中网络设备的资源配置功能,由TRP完成本发明实施例中网络设备的发送接收功能,又或者,在双连接(Dual Connectivity)的场景,UE可以同时连接两个基站,因此这两个基站可以统一称为网络设备,再或者,UE可能同时连接多个TRP,因此该多个TRP可以统一称为网络设备,本发明实施例并不以此为限。
UE可以称为终端(terminal),移动台(mobile station),用户单元(subscriber unit),站台(station)等。UE可以为蜂窝电话(cellular phone),个人数字助理(personal digital assistant,简称为PDA),无线调制解调器(modem),无线通信设备,手持设备(handheld),膝上型电脑(laptop computer),无绳电话(cordless phone),无线本地环路(wireless local loop,简称为WLL)台等。当UE应用于M2M方式通信时,UE可以称为M2M终端,具体可以是支持M2M通信的智能电表、智能家电等。UE也可以为平板、智能汽车、传感设备、物联网(Internet Of Things,IOT)设备、用户驻地设备(Customer-premises equipment,CPE)、中继基站、中继终端,和具有移动终端的计算机,也可以是便携式、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,手机、个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站。无线终端也可以称为用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment,UE)。作为一种实例,在本申请实施例中,图1和图2中均以用户设备40和用户设备70是手机为例示出。
在本发明实施例中,UE可以分布于整个网络中,每个UE可以是静态的或移动的。
如图2所示,网络设备30可以通过Beamforming技术(如数字(Digital)Beamforming或者模拟(Analog)Beamforming)来形成多个传输波束或者接收波束,各个波束所覆盖的角度可以相同或者不同,不同覆盖角度的波束可以存在重叠部分,例如,网络设备30可以用覆盖角度较宽的波束发送控制信息,用覆盖角度 较窄的波束发送数据信息。用户设备40可以在其中的一个或者多个波束或者波束集或波束组的覆盖范围内接收网络设备30发送的信息。
用户设备401也可以通过Beamforming技术形成多个接收波束,对应于网络设备30所使用的下行链路传输波束,确定使用某一个或者多个接收波束来接收。为描述方便,本发明实施例中所涉及的波束可以指代单个或者多个波束。
因此,可以将网络设备30的下行链路传输波束和相应的用户设备的接收波束,或者用户设备的上行链路传输波束和相应的网络设备的下行链路接收波束称为一对波束对(Beam Pair),由该Beam Pair形成的传输链路称为波束对链路(Beam Pair Link,BPL)。例如,当图2中的网络设备30使用波束3作为下行链路传输波束时,用户设备40可以确定使用波束6作为相应的接收波束,波束3与波束6形成一对BPL。当网络设备30或者用户设备40的波束符合波束对应(Beam Correspondence)特征时,可以由传输波束或者接收波束确定对应的接收波束或者传输波束。
本发明实施例中的波束Beam可以理解为空间资源,可以指具有能量传输指向性的发送或接收预编码向量。并且,该发送或接收预编码向量能够通过索引信息进行标识。其中,能量传输指向性可以指在一定空间位置内,接收经过该预编码向量进行预编码处理后的信号具有较好的接收功率,如满足接收解调信噪比等;能量传输指向性也可以指通过该预编码向量接收来自不同空间位置发送的相同信号具有不同的接收功率。
可选地,同一通信设备(比如终端设备或网络设备)可以有不同的预编码向量,不同的设备也可以有不同的预编码向量,即对应不同的波束。
针对通信设备的配置或者能力,一个通信设备在同一时刻可以使用多个不同的预编码向量中的一个或者多个,即同时可以形成一个或多个波束。波束的信息可以通过索引信息进行标识。可选地,所述索引信息可以对应配置UE的资源标识(identity,ID),比如,所述索引信息可以对应配置的信道状态信息参考信号(Channel status information Reference Signal,CSI-RS)的ID或者资源,也可以对应配置的上行探测参考信号(Sounding Reference Signal,SRS)的ID或者资源。或者,可选地,所述索引信息也可以是通过波束承载的信号或信道显示或隐式承载的索引信息,比如,所述索引信息可以是通过波束发送的同步信号或者广播信道指示该波束的索引信息。
Beam Pair可以包括发送端的发送波束和接收端的接收波束,或者,也称作上行波束或下行波束。比如,Beam Pair可以包括gNB Tx Beam传输波束或UE Rx beam接收波束,或者,UE Tx beam传输波束或gNB Rx Beam接收波束,其中,传输波束还可以理解为发送波束。
如图3所示,在本申请实施例的第二种应用场景下,该系统架构还可以包括:一个或多个中继设备50及与中继设备50连接的UE,如图2所示的用户设备60。
如图3所示,中继设备50与网络设备30通过链路2建立连接,中继设备50与用户设备60通过链路3建立连接。
需要说明的是,在如图3所示的场景下,本申请中的中继设备50、网络设备30和用户设备是一个相对的概念,例如,相对于网络设备30,与网络设备30连接 的中继设备50也可以作为一种用户设备;相对于用户设备60,与用户设备60连接的中继设备50也可以视为一种网络设备。因此,本领域的技术人员可以理解,本发明实施例所描述的网络设备也可以包含中继设备,本发明实施例所描述用户设备也可以包含中继设备。
如图4所示,图4示出了本发明实施例提供的一种网络设备的结构示意图,如图4所示,该网络设备,包括:至少一个处理器301、收发器302、存储器304以及总线303。其中,收发器302、处理器301以及存储器304通过总线303相互连接;总线303可以是PCI总线或EISA总线等。总线可以分为地址总线、数据总线、控制总线等。为便于表示,图4中仅用一条粗线表示,但并不表示仅有一根总线或一种类型的总线。

为了便于清楚描述本发明实施例的技术方案,在本发明的实施例中,采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分,本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定。
如图6所示,图6示出了本发明实施例提供的一种上报下行链路传输波束失败的传输方法的流程示意图,包括:
S101、用户设备UE生成波束失败报告,波束失败报告包括第一指示信息和候选波束信息,候选波束信息用于向网络设备指示UE确定的一个或多个候选下行链路传输波束。
需要说明的是,本发明实施例中的波束失败报告用于向网络设备指示正在进行下行链路传输的下行链路传输波束上发生波束失败。
可以理解的是,本发明实施例中在步骤S101之前,本发明实施例中的网络设备与用户设备已经建立了连接。此时UE可以与网络设备仍保持连接,或者UE与网络设备断开连接;UE可以为连接状态或者空闲状态。
为描述方便,本发明实施例中以网络设备为gNB、用户设备为手机为例进行说明。需要说明的是,gNB所实现的部分功能可以由TRP实现,例如接收发送系统帧,本发明实施例对此不限制。
可选的,在本发明实施例中的步骤S101之前,本发明实施例提供的方法还包括:
S107、用户设备与网络设备之间确定下行链路传输波束及相应的接收波束。
具体的,步骤S107可以通过以下方式实现:
一种可能的实现方式为:
S1071、UE在初始接入网络设备的过程之前通过UE建立的一个或多个接收波束中每个接收波束接收gNB在一个或多个下行链路传输波束中每个下行链路传输波束上发送的参考信号。
示例性的,该参考信号可以为同步信号块(Synchronization Signal Block,SS block)或者信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)。
S1072、UE确定在每个接收波束上接收的网络设备在每个下行链路传输波束上发送的参考信号的参数。
可选的,参考信号的参数可以为:参考信号接收功率(Reference Signal Receiving Power,RSRP)、参考信号传输质量(Reference Signal Received Quality, RSRQ)和参考信号强度指示(Received Signal Strength Indicator,RSSI)中的一项或多项组合。
需要说明的是,本发明实施例中UE确定在每个接收波束上接收的网络设备在每个下行链路传输波束上发送的RSRP、RSSI或者RSRP是指:网络设备在每个下行链路传输波束上向用户设备的一个接收波束发送一个参考信号,以供用户设备确定出网络设备在每个下行链路传输波束上发送的参考信号的RSRP、RSSI或者RSRP。
因此,网络设备通常发送的参考信号的次数为:下行链路传输波束的数量与接收波束的数量的乘积,例如,在图3中,网络设备需要发送3×4=12次参考信号。例如,用户设备为了获取在波束1上的RSSI,则网络设备需要在波束1上分别向接收波束5、接收波束6和接收波束7发送参考信号,以供UE获取出通过每个接收波束接收到的在波束1上发送的参考信号的RSSI。
S1073、UE根据每个接收波束上接收的网络设备在每个下行链路传输波束上发送的参考信号的参数,确定出满足预设要求的参考信号所在的下行链路传输波束。
S1074、UE将满足预设要求的参考信号所在的下行链路传输波束的信息发送给网络设备。
S1075、网络设备根据接收到的下行链路传输波束的信息,确定向UE进行下行链路传输的波束。
当然,在实际过程中还可以存在除S1071a-S1074a之外的其余方式用于UE确定满足预设要求的参考信号所在的下行链路传输波束,本申请在此不再赘述,本申请仅是示例性的以S1071a-S1074a为例进行说明。
可选的,UE还可以根据参考信号的参数满足预设要求的参考信号从一个或多个接收波束中选择出一个与满足预设要求的参考信号所在的下行链路传输波束对应的接收波束。
如图2所示,以波束3和波束6为例进行说明。其中,波束3为网络设备根据用户设备发送的下行链路传输波束的信息确定的与UE进行下行链路传输的波束,波束6为由用户设备确定的用于接收网络设备在波束3上发送信息的波束,波束3和波束6可以组成一对波束对。
需要说明的是,gNB与UE之间可用的下行链路传输波束和接收波束可以有多个,gNB在一次传输中也可以使用多个下行链路传输波束,本发明实施例并不以此为限。
在另一种可能的实现方式中,UE和gNB可以在建立连接之后确定下行链路传输波束和相应的接收波束,例如,gNB与UE进行链路波束管理过程,如第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)TR38.802V14.0.0中定义的P-1、P-2、P-3过程的一个或者多个。
由于使用下行链路传输波束传输信号和使用接收波束接收信号的方向性较强,因此,当UE与gNB之间的传输链路情况相较前一时刻发生改变时,例如UE移动、UE与gNB之间的链路遭到遮挡等,可能会导致UE接收gNB下行链路传输的质 量下降。例如,如图7所示,当UE相对于确定的波束6和波束3时的位置发生了移动时,移动之前gNB的波束3与UE的波束6对齐,移动后gNB的波束3不再与UE的波束6对齐,因此,会使得UE接收到网络设备在波束3上的发送的信号传输质量可能会严重下降,例如导致较高的误码率或较低的传输速率。当波束3上的信号传输质量低于第四阈值时,UE判断波束3上发生波束失败。
因此,本发明实施例在步骤S101之前,还包括:
S108、UE确定网络设备进行下行链路传输的下行链路传输波束上发生波束失败。
可选的,步骤S108具体可以通过以下步骤中的一项或多项组合方式来实现:
S1081、UE检测到在进行下行链路传输的下行链路传输波束上产生的误码率高于第一阈值时,UE确定在进行下行链路传输的下行链路传输波束上发生波束失败。
或者,
S1082、UE检测到在进行下行链路传输的下行链路传输波束上的传输速率低于第二阈值时,UE确定在进行下行链路传输的下行链路传输波束上发生波束失败。
或者,
S1083、UE检测到在进行下行链路传输的下行链路传输波束上传输的信号的接收功率小于第三阈值时,UE确定在进行下行链路传输的下行链路传输波束上发生波束失败。
或者,
S1084、UE检测到在进行下行链路传输的下行链路传输波束上传输的信号的传输质量小于第四阈值时,UE确定在进行下行链路传输的下行链路传输波束上发生波束失败。
可选的,本发明实施例中的步骤S1081-S1084中的一项或多项可以进行组合,以使得UE确定在进行下行链路传输的波束上发生波束失败,例如,可以通过步骤S1081和S1082来组合以使得UE确定在进行下行链路传输的波束上发生波束失败;例如,可以通过步骤S1081、S1082和S1083来组合以使得UE确定在进行下行链路传输的波束上发生波束失败,通过将两个或两个以上的判断方式进行组合,可以使得UE更加准确的确定是否在进行下行链路传输的波束上发生波束失败。
可选的,本发明实施例中的第一阈值、第二阈值、第三阈值和第四阈值可以由UE根据需要满足的传输质量或者误码率或者接收功率自行设置,也可以由网络设备配置好之后发送给UE,或者默认设置在UE中,本发明实施例对此不进行限定。
可以理解的是,在实际过程中,UE确定网络设备在进行下行链路传输的下行链路上发生波束失败的方式有很多,本申请仅以S1081-S1084为例进行说明,在实际过程中并不局限于S1081-S1084。
S102、UE在物理上行链路控制信道(Physical Uplink Control Channel,PUCCH)的第一资源上向网络设备发送用户设备UE生成波束失败报告,该波束失败报告中的第一指示信息用于向网络设备指示UE在第一资源上传输的内容为波束失败报告,第一资源用于用户设备发送信道状态信息(Channel State Information,CSI) 报告和/或波束信息报告。
可以理解的是,本发明实施例中的波束失败报告也可以称为:波束失败恢复请求信息或者波束失败报告消息,或者下行链路传输波束失败恢复请求消息,或者下行链路失败报告消息等本申请对此不进行限定。本领域的技术人员可以理解,前述的信息或者消息可以为系统的时域和频域上传输的传输块(transport block)。
可以理解的是,本发明实施例中的第一资源可以用于传输波束失败报告和信道状态信息报告(Channel State Information Reporting),或者第一资源可以用于传输波束失败报告和波束信息报告(Beam Reporting);或者第一资源可以用于传输波束失败报告、信道状态信息报告和波束信息报告。
可选的,本发明实施例在步骤S101之前,还包括:
S109、UE确定一个或多个候选下行链路传输波束。
可选的,本发明实施例中的步骤S109可以通过以下方式实现:
S1091a、UE在检测到网络设备进行下行链路传输的下行链路传输波束发生波束失败的情况下,UE获取网络设备在一个或多个下行链路传输波束中每个下行链路传输波束发送的参考信号的参数。
具体的,步骤S1091a的实现方式可以参见上述实施例所描述的UE确定下行链路传输波束的方式,本发明实施例在此不进行赘述。
S1092a、UE根据获取到的每个下行链路传输波束发送的参考信号的参数,将获取到的参考信号的参数中满足第一预设条件的参考信号所在的下行链路传输波束确定为一个或多个候选下行链路传输波束。
可选的,本发明实施例中的候选波束信息用于识别下行链路传输波束,该候选波束信息可以明确地向网络设备指出一个或多个候选下行链路传输波束,也可以间接地向网络设备指出一个或多个候选下行链路传输波束。
示例性的,当候选波束信息明确地指出一个或多个候选下行链路传输波束时,该候选波束信息可以包括一个或多个候选下行链路传输波束中每个候选下行链路传输波束的标识信息,如波束标识Beam ID,或者波束索引Beam Index等,标识信息用于使网络设备唯一确定候选下行链路传输波束。网络设备通过每个候选下行链路传输波束的标识信息可以确定出下一次向UE进行下行链路传输时的每个候选下行链路传输波束。
又一示例,当候选波束信息间接的向网络设备指出一个或多个候选下行链路传输波束时,该候选波束信息可以包括每个候选下行链路传输波束关联的参考信号资源信息、端口信息、序列信息中的两个或两个以上的组合。上述参考信号资源信息、端口信息、序列信息中的两个或两个以上的组合可以唯一对应到相应的参考信号的下行链路传输波束。例如,候选波束信息可以为用于发送相应波束上的参考信号的资源索引,或者序列索引,或者端口号,或者上述信息中的某一组合。这样便于网络设备确定出每个候选下行链路传输波束。
可以理解的是,本发明实施例中的候选波束信息还可以既包括每个候选下行链路传输波束的标识信息,又包括每个候选下行链路传输波束关联的参考信号资源信息、端口信息、序列信息中的两个或两个以上的组合。这样可以使得网络设备更加 精确地确定出每个候选下行链路传输波束。
如图8所示,若UE确定波束2为候选下行链路传输波束,则候选波束信息包括波束2的标识信息。
需要说明的是,本发明实施例中的候选波束信息还可以不携带任何信息,即候选波束信息为空(NULL),这是由于当UE移出网络设备的下行链路传输波束的覆盖范围时或者UE与网络设备之间的传输链路遭到严重遮挡时,UE无法确定任何可用的候选下行链路传输波束,因此,UE向网络设备发送的波束失败报告中包含的候选波束信息为空。
此外,为了更好地接收网络设备在每个候选下行链路传输波束上发送的信息,本发明实施例中还包括:
S1093a、UE根据参考信号的参数中满足第一预设条件的参考信号所在的接收波束,确定与一个或多个候选下行链路传输波束中每个下行链路传输波束对应的接收波束。
如图8所示,UE确定的与波束2对应的接收波束为波束6。
又一方面,本发明实施例中的步骤S109还可以通过以下方式实现:
S1091b、UE在确定进行下行链路传输的波束上发生波束失败之前,周期性的获取网络设备在一个或多个下行链路传输波束中每个下行链路传输波束发送的参考信号的参数。
S1092b、UE根据每个周期获取到的每个下行链路传输波束发送的参考信号的参数,在检测到进行下行链路传输的波束上发生波束失败时,将最近一个周期获取到的参考信号的参数中满足第一预设条件的参考信号所在的下行链路传输波束确定为一个或多个候选下行链路传输波束。
具体的,如图7所示,UE在确定波束3发生波束失败之前,定期维持包含一个或者多个可用于下行链路传输的下行链路传输波束的集合,例如,当UE与网络设备建立连接之后,UE按照预设周期周期性地或者半周期性地测量网络设备在一个或多个下行链路传输波束(例如,如图7中的波束1、波束2、波束3和波束4),可以理解的是,由于每个下行链路传输波束覆盖的方向不同,因此也可以理解为,UE在各个方向上测量网络设备的每个下行链路传输波束上发送的参考信号的参数,如SS block、CSI-RS、CRS、DMRS等,并从确定出的每个下行链路传输波束上发送的参考信号的参数中选择满足第一预设条件的参考信号所在的下行链路传输波束以及接收波束,UE将该下行链路传输波束确定为网络设备可用于下行链路传输的波束,UE可以将最新确定的满足第一预设条件的参考信号所在的下行链路传输波束中的一个或者多个下行链路传输波束确定为网络设备向UE进行下一次传输的候选下行链路传输波束。
需要说明的是,UE也可以全向接收网络设备在各个下行链路传输波束上发送的参考信号。
S103、网络设备在物理上行链路控制信道的第一资源上接收用户设备UE发送的信息。
S104、网络设备第一指示信息确定在物理上行链路控制信道的第一资源上接 收到的信息为波束失败报告。
S105、网络设备根据波束失败报告确定进行下行链路传输的下行链路传输波束上发生波束失败。
S106、网络设备根据候选波束信息确定下一次向UE进行下行链路传输时使用的一个或多个候选下行链路传输波束。
本发明实施例提供一种波束失败报告发送方法,UE在确定网络设备进行下行链路传输的下行链路传输波束上发生下行链路波束失败之后,通过在物理上行链路控制信道的第一资源上向网络设备发送包括第一指示信息以及候选波束信息的波束失败报告,由于第一资源不仅可以用于发送波束失败报告,还可以用于用户设备发送信道状态信息报告和波束信息报告中的一项或多项,这样在物理上行链路控制信道上的资源有限的情况下,可以将UE用于发送波束失败报告的第一资源与信道状态信息报告和/或波束信息报告共享,以实现在第一资源的不同时刻实现在第一资源上发送不同报告的用途,使得发送波束失败报告不再占用物理上行链路控制信道的其他资源,从而通过较小的资源开销实现UE向网络设备上报进行下行链路传输的下行链路波束发生失败,且可以使UE使用更多的物理上行链路控制信道上的其他资源向网络设备传输数据。
本发明实施例中UE可以根据网络设备发送的第一配置信息确定第一资源用于发送波束失败报告、波束信息报告以及信道状态信息报告中的一种或多种后,并利用第一资源中的域的预定值来向网络设备指示在第一资源上发送的信息为波束失败报告还是波束信息报告,还是信道状态信息报告,另一方面,UE还可以根据网络设备发送的第二配置信息确定在哪个时间段上发送波束失败报告,以使得网络设备根据在第一资源上接收到的信息的时间段确定接收到的信息为波束失败报告还是波束信息报告,还是信道状态信息报告。以下将分别结合两种情况介绍:
可选的,如图9所示,在第一种可能的实现方式中,本发明实施例在步骤S102之前,还可以包括:
S110、网络设备向用户设备发送第一配置信息,该第一配置信息用于指示UE使用物理上行链路控制信道的第一资源发送CSI报告和在检测到进行下行链路传输的下行链路传输波束上发生波束失败时发送波束失败报告;或者第一配置信息用于指示UE使用第一资源发送波束信息报告和在检测到进行下行链路传输的下行链路传输波束上发生波束失败时发送波束失败报告;或者,第一配置信息用于指示UE使用第一资源发送波束信息报告、信道状态信息报告和在检测到进行下行链路传输的下行链路传输波束上发生波束失败时发送波束失败报告。
可选的,本发明实施例中网络设备可以通过无线资源控制(Radio Resource Control,RRC)信令、下行控制信息(Downlink Control Information,DCI)或者介质访问控制控制元素(Medium Access Control Control Element,MAC CE)等方式向用户设备配置第一资源。
可以理解的是,本申请中第一资源的配置可以是由网络设备为UE配置的,也可以是由网络设备之外的其余设备例如,第一网络设备为UE配置的,并由网络设 备发送给UE。本申请对此不进行限定。
具体地,第一资源可以由gNB配置给UE,或者,第一资源可以由其他的网络设备配置给UE,并传输给gNB。例如,当UE在第一时刻可以被一个第一gNB配置PUCCH的第一资源,第一gNB可以通过backhaul或者X2接口将该PUCCH的第一资源配置信息传输给一个第二gNB。该配置可以为一个半静态(semi-statical)配置。当UE在连接该第二gNB后检测发生波束失败时,UE可以通过该PUCCH的第一资源向一个第二gNB发送波束失败报告。其配置过程可以通过RRC信令、DCI或者MAC CE等方式实现。为描述方便,本发明实施例仅以gNB配置该资源给UE为例进行说明。
S111、UE接收网络设备发送的第一配置信息。
示例性的,本发明实施例的第一资源可以用于进行信道状态信息报告和发送波束失败报告,或者用于进行波束信息报告和发送波束失败报告,或者用于进行波束信息报告、信道状态信息报告和发送波束失败报告。
S112、UE根据第一配置信息确定在第一资源上发送波束失败报告。
具体地,网络设备可以向UE指示第一资源在PUCCH上的时域/频域配置,或者网络设备向UE指示计算该第一资源在PUCCH上的时域/频域配置的第一信息,以使得UE根据该第一信息计算出UE在PUCCH上可用的第一资源的时域/频域配置。
其中,时域可以为时隙、子帧、迷你子帧、迷你时隙或正交频分复用技术(Orthogonal Frequency Division Multiplexing,OFDM)符号中的至少一种。
其中,频域或频域资源可以为频带、子带、或PRB中的至少一种。
网络设备可以指示该第一资源在一个时间段中的时域/频域配置,一个时间段中的时域/频域配置可以是根据一个起始时刻(所述起始时刻与进行通知的当前时刻之间的时间关系可以被预先规定或预先配置)和一个时间窗。
可选的,时间段可以作为索引在DCI中被指示,网络设备可以预先将时间段与索引之间的映射关系配置为一个索引表格。例如,网络设备在系统信息中广播该索引表格或通过操作、管理与维护(Operations,Administration and Maintenance,OAM)预先配置该索引表格。
该索引表格采用特定的索引1对应于默认时间段中新的时域/频域配置,采用另一个索引2对应于新的时域/频域配置和对应的有效时间段。通过采用广播信令中预先规定的索引关系、或OAM配置并通知给eNB和UE的索引关系,得到新的DCI设计,该DCI可以为group DCI,有一系列比特对应于特定的索引1的配置、或者有一系列比特对应于特定的索引2与索引1的配置组合。
可选的,网络设备可以向UE指示该第一资源的用途为发送CSI报告及发送波束失败报告,或者第一资源的用途为发送CSI报告、发送波束失败报告及发送波束信息报告,或者,第一资源的用途为发送波束失败报告及发送波束信息报告。
在一种可能的实施方式中,当网络设备向UE配置了该第一资源可以用于发送CSI报告和/或波束信息报告时,UE确定该第一资源也可以用于发送波束失败报告。
在又一种可能的实施方式中,当网络设备向UE配置了该第一资源可以用于发 送波束失败报告时,这样UE确定可以利用PUCCH上的第一资源发送CSI报告和/或波束信息报告。
在另一种可能的实施方式中,网络设备对该第一资源的进行分别指定,如在配置该第一资源时,同时指示该第一资源可以用于发送CSI报告和发送波束失败报告。或者,网络设备分别为UE配置用于发送CSI报告的第一子资源和用于发送波束失败报告的第二子资源,且第一子资源和第二子资源同时指向PUCCH上的同一资源(例如,第一资源)。这样UE确定可以利用PUCCH上的第一资源发送波束失败报告。
或者网络设备指示该第一资源可以用于发送波束失败报告和波束信息报告,或者网络设备分别为UE配置用于发送波束信息报告的第三子资源和用于发送波束失败报告的第二子资源,且第三子资源和第二子资源同时指向PUCCH上的同一资源(例如,第一资源)。这样UE确定可以利用PUCCH上的第一资源发送波束失败报告。
具体该第一资源的用途的具体指示过程可以通过指示该第一资源的格式format来实现,或者通过指示该资源的用途索引值来实现,本发明实施例对此不进行限定。
如图10所示,PUCCH可以位于UE的上行链路传输带宽的两侧,一个PUCCH可以占用一个或者多个时隙(slot),其中用于传输波束失败报告的第一资源可以位于PUCCH上的任何可行的时频位置。如图10所示,一种可能的实现方式为,该第一资源可以位于频带的边界,如图10中所示的资源1;在一个PUCCH中可能有多个可用的资源,例如,资源2也可以用于传输波束失败报告。可以利用多个可用的资源进行传输分集。为描述方便,本发明实施例中,以使用资源1传输波束失败报告为例进行说明。
示例性的,结合图7和图10,当UE检测波束3上发生波束失败时,可以暂时停止在第一资源上传输CSI报告或波束信息报告,并且使用资源1作为传输波束失败报告的上行传输资源。
综上所述,本发明实施例中的步骤S102的一种可能的实现方式为:本发明实施例中的第一资源上传输的内容包括第一域,第一指示信息通过取值为第一预定值的第二域来指示,第一域用于指示第一资源当前时刻发送的内容为波束失败报告或信道状态信息报告或波束信息报告,当第一域取第一预定值时,表示第一资源上当前时刻发送的内容为波束失败报告。也即在此种情况下,UE可以利用第一域中的第一预定值向网络设备指示当前时刻UE在PUCCH的第一资源上发送的内容具体是什么。
示例性的,本发明实施例中,当网络设备向UE配置资源1可以用于发送波束失败报告,发送波束信息报告和/或CSI报告后,当UE在资源1上进行上行传输时,可以通过资源1中的用途指示信息来指示资源1上的传输内容具体为波束信息报告、CSI报告及发送波束失败恢复请求信息中的哪一种。一种可能的实施方式为,在资源1的固定位置传输2比特的用途索引来指示资源1的传输内容。如下表1所示:
表1
资源1用途索引域 资源1传输内容
00 波束失败报告
01 波束信息报告
10 CSI报告
11 其他用途
因此,如表1所示,当UE使用资源1用途索引域为00作为波束失败报告时,网络设备检测到第一资源上包括索引域00时,即可确定UE在第一资源传输的内容为波束失败报告。当用途索引域的值为指示波束信息报告或者CSI报告的值时,其资源1传输内容可以参考上述实施例的描述。
例如,当波束失败报告与CSI报告共用资源1时,在现有的CSI报告的传输块中增加一个2个bit的域,当该域中的取值为00时,表示资源1中传输的内容为波束失败报告;当该域中的取值为10时,表示资源1中传输的内容为CSI报告。因此当网络设备接收资源1中的传输内容时,可以先通这个域中的取值来判断资源1的具体内容。
通过增加少量的用途指示信息的比特资源,使UE可以在资源1上传输不同的内容,因而通过较小的资源开销实现了在PUCCH上传输波束失败报告。
需要说明的是,在实际的实施过程中,并不限于上述表2所列举的域及所列举的域的值。
由于在不同的实施方式中,网络设备通过第一配置信息向UE指示在第一资源上传输的内容不同,例如,网络设备通过第一配置信息向UE指示在第一资源上可以传输波束失败报告和CSI报告,或者也可以传输波束失败报告和波束信息报告,或者也可以传输波束失败报告、CSI报告以及波束信息报告,因此为了使网络设备在PUCCH的第一资源上接收到UE发送的信息时能够准确的解析出UE在第一资源传输的是波束失败报告、CSI报告还是波束信息报告,本发明实施例中的步骤S102的另一种可能的实现方式为:本发明实施例中,对CSI报告或者波束信息报告中的一个或多个参数所在的第二域的某一预定值或者预定值的组合值进行特殊定义,使用该预定值或者组合值作为第一指示信息,以向网络设备指示第一资源上传输的信息为波束失败报告,即使用该预定值(A predetermined valure)或者组合值作为前述的第一指示信息。
当网络设备将资源1配置给UE后,UE可以进行周期性地或者非周期性地发送CSI报告,并携带CSI报告参数。
基于现有的3GPP TR38.802V14.0.0,当UE进行CSI报告时,如果进行第一类型反馈(Type I feedback),其CSI报告的参数如表2所示:
表2 CSI报告的参数
Figure PCTCN2017089415-appb-000001
另外,CSI报告的参数中还可以包括预编码类型指示(Precoding Type Indicator,PTI)等其他信道状态信息。
对应于不同的传输模式(Transmission mode),UE可能需要上报不同的CSI参数信息。
可选的,本发明实施例中的第一资源上传输的内容包括至少一个第二域,第一指示信息通过取值为第二预定值的第二域来指示,第二域用于指示第一资源当前时刻发送的内容为UE发送的CSI报告参数中的一个或多个参数或UE发送的波束失败报告,当第二域取第二预定值时,第二域用于向网络设备指示UE当前时刻在所述第一资源发送的内容为波束失败报告,第二预定值为CSI报告参数中的一个参数的取值或预留值,或者,第二预定值可以为CSI报告参数中的多个参数的取值或预留值的组合中的一个;或者,第二域用于指示第一资源当前时刻发送的内容为UE发送的波束信息报告的一个或多个参数或UE发送的波束失败报告,当第二域取第二预定值时,第二域用于指示UE发送的是第一资源当前时刻发送的内容为UE发送的波束失败报告,第二预定值可以为波束信息报告的一个参数的取值或预留值,或者,第二预定值为波束信息报告的多个参数的取值或预留值的组合中的一个。
可选的,CSI报告的参数包括:资源选择指示、秩指示RI、预编码矩阵指示PMI、下行链路信道质量CQI、预编码类型指示PTI、下行链路CSI等中的一个或者多个,可以理解的是,在实际过程中CSI报告还可以包括其他的参数,本申请对此不进行限定,因为无论CSI报告包括哪些参数,本发明实施例均以该参数所对应的第二域中的预定值作为第一指示信息。
可选的,本发明实施例中的波束信息报告的参数包括:参考信号接收功率RSRP、参考信号接收质量RSRQ、接收信号强度指示RSSI等中的一个或者多个。可以理解的是,在实际过程中波束信息报告还可以包括其他的参数, 本申请对此不进行限定,因为无论波束信息报告包括哪些参数,本发明实施例均以该参数所对应的第二域中的预定值作为第一指示信息。
示例性的,第二域的预定值可以为参数的取值或预留值,如参数为5bit,表示该域的取值范围可以为0~31,当表示某个具体参数信息时,对应的取值为0~29中的某一个,则该参数对应的预留值为30和31。则可以使用30或者31来作为第一指示信息。
示例性的,第二域的预定值可以为参数的某个取值,如参数为5bit,表示该域的取值范围可以为0~31,当表示某个具体参数信息时,对应的取值为0~29中的某一个,可以使用0来作为第一指示信息,这种情况下,取值0可以同时代表参数信息和第一指示信息,例如,CSI参数中的CQI=0表示UE在网络设备的范围外,则可以定义这种情况同时代表发生波束失败。
具体的,第一资源上传输的内容包括第一第二域,第一第二域用于指示UE上报的资源选择指示,其中,第一第二域为第一资源包括的至少一个第二域中与CSI报告中的资源选择指示对应的第二域。则第一指示信息为第一第二域中的第二预定值。
例如,当网络设备配置UE的CSI报告需要上报资源选择指示时,UE使用特殊的参考信号资源信息、端口信息、参考信号序列信息或波束信息作为第一指示信息。例如,参考信号资源信息为资源索引值时,UE在第二域中使用某一资源索引值的预留值(reserved value)作为第一指示信息;当端口信息为端口号时,UE在第二域中使用未被定义到具体端口的某一端口号的值作为下行链路传输波束失败指示信息;当参考信号序列信息为参考信号序列时,UE在第二域中使用一特殊定义的序列作为第一指示信息;当波束信息为波束标识时,在第二域中使用一未被定义为具体波束标识的值作为第一指示信息。
具体的,第一资源上传输的内容包括第二第二域,第二第二域用于指示UE上报的秩指示,第二第二域与CSI报告中的秩指示对应,第一指示信息为第二第二域中的第二预定值。
需要说明的是,上述第一预定值为第一域中的任意一个预定值,第二预定值为第二域中的任意一个预定值。
示例性的,当网络设备配置UE的CSI报告需要上报RI时,UE可以使用RI域(也即第二第二域)的第二预定值作为第一指示信息。例如,使用RI域的第二预定值为0作为第一指示信息。可以理解的是,第二预定值可以RI域的多个预定值中的任一个预定值。
可选的,第一资源包括第三第二域,第三第二域用于指示用户设备报告的预编码矩阵指示PMI,第三第二域与CSI报告包括的一个或多个参数中的PMI参数对应,第一指示信息为第三第二域中的第二预定值。
示例性的,当网络设备配置UE的CSI报告需要上报PMI时,可以使用某一PMI域(第三第二域)的第二域预定值作为第一指示信息。例如,使用PMI域的第二域预定值为0作为第一指示信息。可以理解的是,第二域 预定值可以PMI域的多个预定值中的任一个预定值。
可选的,第一资源包括第四第二域,第四第二域用于指示用户设备确定的下行链路信道质量CQI,第四第二域为与CSI报告包括的一个或多个参数中的CQI参数对应。在此种情况下,第一指示信息为第四第二域中的第二预定值。
示例性的,当网络设备配置UE的CSI报告需要上报信道质量指示(Channel Quality Indicator,CQI)时,UE可以使用某一CQI域的第二预定值作为第一指示信息。
例如,当CQI域的长度为5比特时,UE使用CQI域的第二预定值为31作为第一指示信息。或者,使用CQI域中的第二预定值为0作为第一指示信息。
可选的,第一资源包括第五第二域,第五第二域用于指示用户设备报告的预编码类型指示PTI,第五第二域与CSI报告包括的一个或多个参数中的PTI参数对应,UE将第五第二域中的第二预定值作为第一指示信息。
示例性的,当网络设备配置UE的CSI报告需要上报PTI时,UE可以使用某一PTI域的第二预定值作为第一指示信息。例如,使用PTI域的第二预定值为0作为第一指示信息。
可以理解的是,本发明实施例中可以将第一域至至少一个第二域中两个或两个以上的域中的预定值进行组合,并将组合后得到的预定值作为第一指示信息。
可选的,第二预定值由CSI报告的参数中两个或两个以上参数分别对应的第二域中的预定值进行组合得到;或者,第二预定值由波束失败报告的参数中两个或两个以上参数分别对应的第二域中的预定值进行组合得到;或者,第二预定值由波束失败报告的参数和CSI报告的参数中两个或两个以上参数分别对应的第二域中的预定值组合得到的。
示例性的,当网络设备配置UE的CSI报告需要上报如表1所示的CSI参数中的两个或者两个以上的参数时,UE可以使用两个或者两个以上的参数的域的组合值为一个预定值作为网络设备,例如,当UE需要在CSI报告中报告CQI和RI时,可以使用CQI域和RI域的值均为0作为第一指示信息。
可选的,本发明实施例中当UE发送的波束信息报告中包括:参考信号接收功率、参考信号接收质量或接收信号强度指示时,本发明实施例中可以用第一资源包括的第六第二域指示用户设备确定的参考信号接收功率RSRP或参考信号接收质量RSRQ或接收信号强度指示RSSI,因此,本发明实施例中的第一指示信息还可以为第六第二域中的第二预定值,例如,用RSSI或RSRP或RSRQ为0来表示第一指示信息。
需要说明的是,当波束信息报告的参数为包括RSRP、RSRQ、RSSI、CSI报告参数的至少两种时,UE可以使用其中至少两种参数的域为某一组合值作为第一指示信息。
需要说明的是,在实际的实施过程中,并不限于上述所列举的域及所列举的域的预定值。
可选的,本发明实施例中UE可以利用第一资源中除至少一个第二域和第一域之外的其余一个或者多个域携带候选波束信息,候选域为携带第一指示信息的域。
示例性的,如图10所示,UE使用资源1中的除用于指示第一指示信息的域或者其他比特位资源来携带候选波束信息。例如,当使用CQI域的特定值作为第一指示信息时,资源1中剩余的域或者剩余的比特位即可用于携带候选波束信息。
具体的,UE可以使用资源选择指示域、RI域、PMI域、PTI域中的任一个或者多个的域的比特位来携带候选波束信息。又例如,当使用RSRP域的特定值作为下行链路传输波束失败指示信息时,资源1中剩余的比特位即可用于携带候选波束信息。
需要说明的是,本发明实施例中还可以将第一指示信息和候选波束信息利用第一资源的同一域中特殊预定值进行指示,例如将第一指示信息和候选波束信息在第一资源的第一域中的特殊预定值进行指示,或者将第一指示信息和候选波束信息在第二域中的特殊预定值进行指示。此时,该特殊预定值既表明了一个或多个候选下行链路传输波束,又隐含向网络设备指示出发生了波束失败。
需要说明的是,下行链路传输波束失败也可以认为是波束信息报告的一种特殊情况。因此,相应地,当网络设备在PUCCH的资源1的相应域中检测到上述的预定值后,即可判定资源1上传输的为波束失败报告。
通过上述实施方式,可以在不增加资源开销的情况下通过PUCCH向网络设备发送波束报告。
因此,在第一资源包括第一域时,本发明实施例中的步骤S104具体可以通过以下方式实现:
S1041、网络设备确定第一域中包括第一预定值,则确定在第一资源上接收到的用户设备发送的信息为波束失败报告。
在第一资源上传输的内容包括至少一个第二域时,本发明实施例中的步骤S104具体可以通过以下方式实现:
S1042、网络设备确定第二域取值为第二预定值,则确定在第一资源上接收到的用户设备发送的信息为波束失败报告。
具体的,例如,网络设备确定第一第二域中包括第二预定值,则确定在第一资源上接收到的用户设备发送的信息为波束失败报告。
例如,网络设备确定第二第二域中包括第二预定值,则确定在第一资源上接收到的用户设备发送的信息为波束失败报告。
例如,网络设备确定第三第二域中包括第二预定值,则确定在第一资源上接收到的用户设备发送的信息为波束失败报告。
例如,网络设备确定第四第二域中包括第二预定值,则确定第一资源上 接收到的用户设备发送的信息为波束失败报告。
例如,网络设备确定第五第二域中包括第二预定值,则确定第一资源上接收到的用户设备发送的信息为波束失败报告。
例如,网络设备确定第六第二域中包括第二预定值,则确定第一资源上接收到的用户设备发送的信息为波束失败报告。
需要说明的是,本发明实施例中的任意两个或两个以上的第二域中的第二预定值可以相同也可以不相同,例如,第一第二域和第二第二域中的第二预定值可以相同,也可以不相同。
可以理解的是,上述步骤中涉及的第一预定值和第二预定值在实际过程中UE和网络设备之间默认某一个预定值用于指示第一指示信息,这样网络设备在接收到包括某一预定值的域时即可确定下行链路传输的波束上发生波束失败,或者UE和网络设备双方之间协商之后确定某一个预定值用于指示第一指示信息,本发明实施例对此不进行限定。
在第二种可能的实现方式中,如图11所示,本发明实施例在S102之前还包括:
S113、网络设备向UE发送第二配置信息,第二配置信息用于指示UE在特定时间段在物理上行链路控制信道的上使用第一资源发送波束失败报告。
具体的,网络设备向UE发送第二配置信息,第二配置信息用于指示UE每个时间段在物理上行链路控制信道的上使用第一资源的传输的内容,其中,不同时间段UE在物理上行链路控制信道的上使用第一资源传输的内容不同。传输的内容可以为波束失败报告、波束信息报告或者CSI报告。例如,第二配置信息用于指示UE在第一时间段使用第一资源发送波束信息报告,在特定时间段使用第一资源发送波束失败报告;或者第二配置信息用于指示UE在第二时间段使用第一资源发送CSI报告,在特定时间段使用第一资源发送波束失败报告;或者第二配置信息用于指示UE在第一时间段发送波束信息报告,在第二时间段使用第一资源发送CSI报告,在特定时间段使用第一资源发送波束失败报告。
S114、UE接收网络设备发送的第二配置信息。
S115、UE根据第二配置信息确定在PUCCH的第一资源的特定时间段上向网络设备发送波束失败报告。相应的,在如图11所示的场景下,步骤S102具体还可以通过步骤S116具体实现:
S116、UE在PUCCH的第一资源的特定时间段上向网络设备发送波束失败报告。
通过网络设备向UE配置第二配置信息这样实现了PUCCH上不同时间段第一资源的不同用途,增加了第一资源利用的灵活性。
此外,本发明实施例中的步骤S104还可以通过以下方式实施:
S1043、网络设备将特定时间段之后在第一资源上接收到的UE发送的内容确定为波束失败报告,所述特定时间段为网络设备指示UE在第一资源 上发送波束失败报告的时间段。
示例性的,以图10为例,当网络设备配置资源1给UE后,该资源1可以用于UE发送波束信息报告、CSI报告及发送波束失败报告,也可以用资源1发送波束信息报告和波束信息报告,也可以用资源1发送CSI报告及发送波束失败报告。在本发明实施例中,网络设备通过下行信令来指定资源1在一段时间内的具体用途。
例如,在一种可能的实施方案中,在第一时刻,网络设备可以发送第一DCI来指示UE,资源1从UE接收该第一DCI时刻起,用于UE进行波束信息报告;在第二时刻,网络设备发送第二DCI来指示UE,资源1从UE接收该第二DCI时刻起,用于UE进行CSI报告;在第三时刻,网络设备发送第三DCI来指示UE,资源1从UE接收该第三DCI时刻时,用于UE发送波束失败报告。因此,当资源1被网络设备配置用于发送波束失败报告后,若UE检测到波束3上发生波束失败,则可以通过资源1传输波束失败报告,相应地,当网络设备在第三时刻后接收到资源1中的传输内容时,网络设备认为其接收到的内容为波束失败报告。具体地,网络设备可以在相应的DCI中通过资源1用途索引值来指示,具体指示如表2所示,本申请对此不再赘述。
或者,在另一种可能的实施方案中,网络设备向UE发送DCI,资源1从UE接收到该DCI后,可以被波束信息报告、CSI报告及波束失败恢复请求信息的任意两种的组合或者三种所共享。因此,当UE检测到波束3上发生波束失败时,UE可以通过上述实施例所描述的方法在第一资源上发送波束失败报告,例如,在资源1的固定位置传输2比特的用途索引来实现,例如,用于第一资源中的某一个域中的预定值来实现,又例如用资源选择指示来实现。
或者,在又一种可能的实施方案中,网络设备发送DCI来指示UE,该资源可以被以何种方式进行共享。例如,通过上述实施例中的对资源1中的某一域或者某几个域的值进行特殊指定来指示资源1的用途,还是通过上述实施例中的在资源1的固定位置传输2比特的用途索引来指示资源1的用途。
相应地,网络设备得知UE在资源1上传输的具体内容,从而可以正确获取UE传输的波束失败恢复请求信息。
需要说明的是,本发明实施例中的第二配置信息可以在第一配置信息之后由网络设备发送给UE,在此种情况下,则可以省略UE利用第一资源中的第一域中的第一预定值或利用第二域中的第二预定值向网络设备指示第一资源上发送的内容为波束失败报告的过程。
当然,本发明实施例中的网络设备也可以仅向UE发送第一配置信息,也可以仅向UE发送第二配置信息,仅发送第一配置信息和仅发送第二配置信息时,UE在第一资源上向网络设备指示接收到的内容是波束失败报告的方式分别参见上述实施例的描述,本申请对此不再赘述。
需要说明的是,上述主要讲述了如何复用第一资源实现既发送波束失败报告又发送波束信息报告,或者如何复用第一资源实现既发送CSI报告又发送波束失败报告,或者如何复用第一资源既发送CSI报告又发送波束信息报告以及发送波束失败报告的过程,在复用第一资源的情况下,可以避免在PUCCH上引入其他资源从而带来的开销大的问题,但是在实际过程中,由于PUCCH的时延小,本发明实施例中网络设备还可以为UE在PUCCH上配置一个专门用于传输波束失败报告的资源,因此,本发明实施例中在步骤S102之前还包括:
S117、网络设备向UE发送第三配置信息,该第三配置信息用于指示UE在确定网络设备在进行下行链路传输的下行链路传输波束发生失败后,通过PUCCH上的第二资源发送波束失败报告,且该第二资源用于UE专门发送波束失败报告。
S118、UE接收第三配置信息。
S119、UE根据第三配置信息在PUCCH的第二资源上向网络设备发送波束失败报告。
在这种情况下,本发明实施例还包括:
S120、网络设备在PUCCH的第二资源上接收UE发送的波束失败报告,由于UE和网络设备之间已经确定在第二资源上发送波束失败报告,因此,网络设备在第二资源上接收到信息后可以直接确定接收到的内容为波束失败报告,这样避免了网络设备区分在第二资源上接收到的信息为哪一种的过程。
示例性的,如图7所示,当UE检测到波束3上发生波束失败时,UE在资源1上传输波束失败恢复请求信息。因此,相应地,网络设备可以得知UE在资源1上传输的具体内容,从而可以正确获取UE传输的波束失败报告,并确定在进行下行链路传输的下行链路传输波束发生失败以及确定候选波束信息所指示的一个或多个候选下行链路传输波束。
需要说明的是,本发明实施例中的波束失败报告中还包括第二指示信息,用于指示网络设备对下行链路传输波束进行波束训练,以使得UE从训练后的下行链路传输波束中选择满足UE的需求的下行链路传输波束。
本发明实施例中的第二指示信息的大小可以为1bit,例如,第二指示信息为指示符,该指示符为第一指示符或第二指示符,其中,第一指示符用于指示网络设备训练下行链路传输波束,第二指示符用于指示网络设备对下行链路传输波束不训练。
当然,另一种实现方式中,第二指示信息可以与第一资源一个域中的一个比特位关联,这样网络设备和UE双方默认与第二指示信息关联的比特位上存在指示符时,则表示需要对下行链路传输波束训练,网络设备和UE双方默认与第二指示信息关联的比特位上不存在指示符时,则表示需要对下行链路传输波束训练。可以理解的是,与第二指示信息关联的比特位上不存在指示符表示与第二指示信息关联的比特位上为空。
例如,当UE确定候选下行链路传输波束的传输质量不足以满足某一传输场景所要求的传输质量时,或者,当UE确定的候选下行链路传输波束的覆盖范围与后续某一传输场景所要求的覆盖范围不匹配时,UE进一步指示网络设备后续需要对一个或多个候选下行链路传输波束进行相应的波束训练。网络设备最终是否对一个或多个候选下行链路传输波束进行相应的波束训练时将根据该第二指示信息的参数确定。
