Description

一种信道质量信息的上报方法及装置
本申请要求于2017年06月06日提交中国专利局、申请号为201710418246.4、申请名称为“一种信道质量信息的上报方法及装置”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。
技术领域
本申请涉及通信技术领域,尤其涉及一种信道质量信息的上报方法及装置。
背景技术
波束赋形技术是一种基于天线阵列的信号预处理技术,通过调整天线阵列中每个阵元的加权系数产生具有指向性的波束,从而通过较大的天线增益来补偿信号(尤其是高频信号)传播过程中的传播损耗。
在下行信号传输过程中,网络设备发射侧的波束赋形和用户设备接收侧的波束赋形均可能发生动态变化。为了跟踪波束赋形的变化,网络设备通常会为用户设备配置N(N>1)个候选赋形波束,网络设备在N个赋形波束上向用户设备发送信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS),用户设备对N个赋形波束上的CSI-RS进行信道质量测量,根据测量结果得到T(N≥T≥1)个波束质量较优的赋形波束并上报给网络设备。在进行下行信号传输时,网络设备可在用户设备上报的T个波束质量较优的赋形波束下发送下行信号。
在上述方式中,存在如下问题:由于N个赋形波束并不能覆盖用户设备可能移动到的所有方向,因而,用户设备的移动会导致如下问题:用户设备对N个赋形波束下的CSI-RS进行信道质量测量时,N个CSI-RS的信道质量都较差,均无法满足信号传输的需求,从而导致用户设备无法筛选出波束质量较优的赋形波束并上报给网络设备,导致通信链路传输的失败。
综上,现有技术提供的方案中,会由于用户设备的移动而导致用户设备无法筛选出波束质量较优的赋形波束并上报给网络设备,从而导致通信链路传输的失败。
发明内容
本申请提供一种信道质量信息的上报方法及装置,用以解决现有技术中存在的、由于用户设备的移动而导致的通信链路传输失败的问题。
第一方面,本申请实施例提供一种信道质量信息的上报方法,该方法包括如下步骤:用户设备接收网络设备在第一参考信号资源上发送的P1个第一参考信号以及网络设备在第二参考信号资源上发送的P2个第二参考信号,其中,P1≥1,P2≥1;然后,用户设备对第一参考信号和第二参考信号进行信道质量测量,并基于信道质量测量的结果向网络设备上报M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,以及上报M个参考信号资源索引对应的参考信号类型或参考信号资源集合的索引,M≥1。
其中,第一参考信号资源对应了多个赋形波束,其中每个赋形波束的方向不同。网络设备在第一参考信号资源上向用户设备发送P1个第一参考信号,即在P1个不同的波束方 向上向用户设备发送第一参考信号。同样地,第二参考信号资源也对应了多个赋形波束,其中每个赋形波束的方向不同。网络设备在第二参考信号资源上向用户设备发送P2个第二参考信号,即在P2个不同的波束方向上向用户设备发送第二参考信号。
通过上述方法,由于用户设备对网络设备发送的P1个第一参考信号以及P2个第二参考信号进行信道质量测量,根据信道质量测量的结果选择上报M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,并上报M个参考信号资源索引对应的参考信号类型或参考信号资源集合的索引。因而,网络设备可根据用户设备上报的如上信息,确定用户设备从(P1个第一参考信号对应的)P1个候选赋形波束和/或(P2个第二参考信号对应的)P2个候选赋形波束中选择的M个赋形波束具体是哪一个或哪几个赋形波束,进而将M个赋形波束中的一个赋形波束作为该用户设备的服务赋形波束,在后续进行下行传输时,在该服务赋形波束下向用户设备发送下行信号,从而通过较大的天线增益来补偿信号(尤其是高频信号)传播过程中的传播损耗。
此外,在上述方法中,用户设备基于第一参考信号和第二参考信号两种类型的参考信号进行信道质量信息上报,与现有技术中仅基于CSI-RS进行信道质量信息上报的方案相比,当用户设备移动到某类参考信号(第一参考信号或第二参考信号)的覆盖范围之外时,用户设备仍可基于另一类参考信号(第二参考信号或第一参考信号)选择并上报M个波束质量较优的赋形波束。因此,采用上述方法,在用户设备发生移动时,用户设备仍可筛选并上报波束质量较优的赋形波束,从而避免通信链路传输失败。
特别地,当第一参考信号为用户特定的参考信号、第二参考信号为小区特定的参考信号时,由于小区特定的参考信号能够覆盖小区内的所有方向,因而无论用户设备移动到小区内的哪个方向,用户设备均可以从(P2个第二参考信号对应的)P2个候选赋形波束中筛选并上报M个波束质量较优的赋形波束,从而避免通信链路传输失败。
在一种可能的设计中,所述参考信号资源索引对应的信道质量信息包括以下至少一种:
参考信号接收功率(Reference Signal Received Power,RSRP);
参考信号接收质量(Reference Signal Received Quality,RSRQ)。
在一种可能的设计中,用户设备向网络设备上报M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,并上报M个参考信号资源索引对应的参考信号类型或参考信号资源集合的索引,具体可通过如下方式实现:当第一参考信号对应的信道质量与第二参考信号对应的信道质量之差大于等于第一门限值时,用户设备从P1个第一参考信号中选择M个第一参考信号,上报M个第一参考信号资源索引及M个第一参考信号资源索引对应的信道质量信息,并上报M个第一参考信号的参考信号类型或参考信号资源集合的索引;或,当第二参考信号对应的信道质量与第一参考信号对应的信道质量之差大于等于第二门限值时,用户设备从P2个第二参考信号中选择M个第二参考信号,上报M个第二参考信号资源索引及M个第二参考信号资源索引对应的信道质量信息,并上报M个第二参考信号的参考信号类型或参考信号资源集合的索引。
通过上述方法,用户设备仅上报基于一类参考信号的信道质量测量结果,因而可以减小用户设备的上报开销。
此外,在上述方法中,用户设备还可向网络设备上报用户设备的功率控制所基于的参考信号类型或参考信号资源集合的索引。那么,网络设备在获知用户设备的功率控制所基 于的参考信号类型或参考信号资源集合索引后,可进一步对用户设备的发射功率进行控制。
在一种可能的设计中,用户设备向网络设备上报M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,并上报M个参考信号资源索引对应的参考信号类型或参考信号资源集合的索引,具体可通过如下方式实现:用户设备从P1个第一参考信号中选择M1个第一参考信号和从P2个第二参考信号选择M2个第二参考信号,1≤M1≤P1,1≤M2≤P2,M=M1+M2;用户设备向网络设备上报如下信息:M1个第一参考信号资源索引及M1个第一参考信号资源索引对应的信道质量信息;M1个第一参考信号资源索引对应的参考信号类型或参考信号资源集合的索引;M2个第二参考信号资源索引及M2个第二参考信号资源索引对应的信道质量信息;M2个第二参考信号资源索引对应的参考信号类型或参考信号资源集合的索引。
通过上述方法,用户设备可基于网络设备的配置对两种类型的参考信号的信道质量测量结果均进行上报,从而满足网络设备的配置需求。
为了减小用户设备的上报开销,可设置用户设备在上报两种类型的信道质量测量结果时,基于统一的上报格式进行上报。统一两种类型的信道质量测量结果的上报格式的方案包括但不限于如下两种:
方案一
在用户设备对第一参考信号和第二参考信号进行信道质量测量之前,用户设备还可接收网络设备发送的第一通知消息,该第一通知消息用于指示用户设备接收第一参考信号的第一测量时间窗;或,用户设备接收网络设备发送的第二通知消息,该第二通知消息用于指示用户设备接收第二参考信号的第二测量时间窗。
通过上述方法,当网络设备可通过第一通知消息指示用户设备接收第一参考信号的第一测量时间窗时,用户设备可在第一测量时间窗下接收第一参考信号,使得在第一测量时间窗下接收到的P1个第一参考信号的数量与P2个第二参考信号的数量相同或相近,那么此时,第一参考信号资源索引的上报比特数为可以与第二参考信号资源索引的上报比特数相同;当网络设备可通过第二通知消息指示用户设备接收第二参考信号的第二测量时间窗时,用户设备可在第二测量时间窗下接收第二参考信号,使得在第二测量时间窗下接收到的P2个第二参考信号的数量与P1个第一参考信号的数量相同或相近,那么此时,第一参考信号资源索引的上报比特数为可以与第二参考信号资源索引的上报比特数相同。采用方案一来统一第一参考信号资源索引和第二参考信号资源索引的上报比特数,可减小用户设备的上报开销。
方案二
在用户设备对第一参考信号和第二参考信号进行信道质量测量之前,用户设备还可接收网络设备发送的第三通知消息,该第三通知消息用于指示用户设备在对第二参考信号进行信道质量测量时的一个第二参考信号测量子集,第二参考信号测量子集包含P2个第二参考信号中的部分第二参考信号;用户设备对第二参考信号进行信道质量测量,具体包括:用户设备对第二参考信号测量子集进行信道质量测量。
通过上述方法,当第一参考信号为用户特定的参考信号、第二参考信号为小区特定的参考信号时,第一参考信号资源索引的上报比特数通常小于第二参考信号资源索引的上报比特数,因而若要统一第一参考信号资源索引和第二参考信号资源索引的上报比特数,网 络设备可指示用户设备仅对接收到的P2个第二参考信号中的部分第二参考信号进行信道质量测量,从而进行信道质量测量的第二参考信号的数量与进行信道质量测量的第一参考信号的数量相同或相当,那么此时,第二参考信号资源索引的上报比特数为可以与第一参考信号资源索引的上报比特数相同。采用方案二来统一第一参考信号资源索引和第二参考信号资源索引的上报比特数,可减小用户设备的上报开销。
在一种可能的设计中,用户设备还可接收网络设备发送的第四通知消息,该第四通知消息用于指示用户设备在进行功率控制时所基于的参考信号类型或参考信号资源集合的索引。
通过上述方法,第四通知消息可用于用户设备在向网络设备发送上行信号时根据该参考信号类型或参考信号资源集合的索引设置或调整发射功率。
在一种可能的设计中,用户设备还可接收网络设备发送的指示信息,该指示信息用于指示网络设备配置的同位置(Quasi-Co-Location,QCL)假设指示对应的参考信号类型或参考信号资源集合的索引。
其中,QCL假设指示可用来辅助描述用户设备的接收侧波束赋形信息以及用户设备的接收流程。
通过上述方法,当QCL假设指示对应的参考信号类型为用户特定的参考信号时,用户设备在后续接收数据的过程中基于上报的M1个第一参考信号对应的赋形波束进行数据接收,否则用户设备基于上报的M2个第二参考信号对应的赋形波束进行数据接收。
此外,为了节省网络设备对用户设备的QCL假设指示的开销,网络设备发送给用户设备的QCL假设指示中可限定:网络设备发送给用户设备的QCL假设指示所对应的有效时间窗。用户设备在S204中上报的M个赋形波束对中的一个是满足QCL假设的。
在一种可能的设计中,用户设备上报M个参考信号资源索引对应的信道质量信息,具体包括:用户设备根据M个参考信号资源索引对应的信道质量信息,上报L个参考信号资源索引组的信道质量信息,L≥1。
其中,L个参考信号资源索引组中每个参考信号资源索引组包含的参考信号资源索引共同构成M个参考信号资源索引,L个参考信号资源索引组对应的波束组类型为第一类型或第二类型,波束组类型为第一类型的参考信号资源索引组中的每个赋形波束可被用户设备同时接收到,波束组类型为第二类型的参考信号资源索引组中的每个赋形波束不可被用户设备同时接收到。
通过上述方法,用户设备可在上报M个参考信号资源索引对应的信道质量信息时采用分组上报的方式,从而减小M个参考信号资源索引对应的信道质量信息时的资源开销。
此外,在采用上述分组上报的方式时,用户设备还可向网络设备上报L个参考信号资源索引组对应的波束组类型。
第二方面,本申请实施例提供一种信道质量信息的上报方法,该方法包括如下步骤:网络设备在第一参考信号资源上向用户设备发送P1个第一参考信号,并在第二参考信号资源上向用户设备发送P2个第二参考信号,P1≥1,P2≥1,第一参考信号和第二参考信号用于用户设备进行信道质量测量;网络设备接收用户设备根据信道质量测量结果上报的M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,以及M个参考信号资源索引对应的参考信号类型或参考信号资源集合的索引,M≥1。
通过上述方法,由于用户设备对网络设备发送的P1个第一参考信号以及P2个第二参 考信号进行信道质量测量,根据信道质量测量的结果选择上报M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,并上报M个参考信号资源索引对应的参考信号类型或参考信号资源集合的索引。因而,网络设备可根据用户设备上报的如上信息,确定用户设备从(P1个第一参考信号对应的)P1个候选赋形波束和/或(P2个第二参考信号对应的)P2个候选赋形波束中选择的M个赋形波束具体是哪一个或哪几个赋形波束,进而将M个赋形波束中的一个赋形波束作为该用户设备的服务赋形波束,在后续进行下行传输时,在该服务赋形波束下向用户设备发送下行信号,从而通过较大的天线增益来补偿信号(尤其是高频信号)传播过程中的传播损耗。
此外,在上述方法中,用户设备基于第一参考信号和第二参考信号两种类型的参考信号进行信道质量信息上报,与现有技术中仅基于CSI-RS进行信道质量信息上报的方案相比,当用户设备移动到某类参考信号(第一参考信号或第二参考信号)的覆盖范围之外时,用户设备仍可基于另一类参考信号(第二参考信号或第一参考信号)选择并上报M个波束质量较优的赋形波束。因此,采用上述方法,在用户设备发生移动时,用户设备仍可筛选并上报波束质量较优的赋形波束,从而避免通信链路传输失败。
特别地,当第一参考信号为用户特定的参考信号、第二参考信号为小区特定的参考信号时,由于小区特定的参考信号能够覆盖小区内的所有方向,因而无论用户设备移动到小区内的哪个方向,用户设备均可以从(P2个第二参考信号对应的)P2个候选赋形波束中筛选并上报M个波束质量较优的赋形波束,从而避免通信链路传输失败。

在一种可能的设计中,网络设备接收用户设备根据信道质量测量结果上报的M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,以及M个参考信号资源索引对应的参考信号类型或参考信号资源集合的索引,具体可通过如下方式实现:当第一参考信号对应的信道质量与第二参考信号对应的信道质量之差大于第一门限值时,网络设备接收用户设备根据信道质量测量结果上报的M个第一参考信号资源索引及M个第一参考信号资源索引对应的信道质量信息,以及M个第一参考信号资源索引对应的参考信号类型或参考信号资源集合的索引;或,当第二参考信号对应的信道质量与第一参考信号对应的信道质量之差大于第二门限值时,网络设备接收用户设备根据信道质量测量结果上报的M个第二参考信号资源索引及M个第二参考信号资源索引对应的信道质量信息,以及M个第二参考信号资源索引对应的参考信号类型或参考信号资源集合的索引。
通过上述方法,用户设备仅上报基于一类参考信号的信道质量测量结果,因而可以减小用户设备的上报开销。
此外,在上述方法中,网络设备还可接收用户设备上报的、用户设备的功率控制参数所基于的参考信号类型或参考信号资源集合的索引。那么,网络设备在获知用户设备的功率控制所基于的参考信号类型或参考信号资源集合索引后,可进一步对用户设备的发射功率进行控制。

具体实施方式
在无线通信系统中,波束赋形技术是一种基于天线阵列的信号预处理技术,通过调整天线阵列中每个阵元的加权系数产生具有指向性的波束,从而通过较大的天线增益来补偿信号(尤其是高频信号)传播过程中的传播损耗。
对于下行信号的传输,网络设备在具有指向性的赋形波束上向用户设备发送下行信号,这里的“具有指向性的赋形波束”通常通过如下方式获取:网络设备为用户设备配置N(N>1)个候选赋形波束,并在N个赋形波束上向用户设备发送CSI-RS,用户设备对N个赋形波束上的CSI-RS进行信道质量测量,根据测量结果得到T(N≥T≥1)个波束质量较优的赋形波束并上报给网络设备。网络设备将上报的T个赋形波束中的一个赋形波束作为该用户设备的服务赋形波束(即上述“具有指向性的赋形波束”),其余赋形波束作为该用户设备的备选赋形波束。
在上述确定用户设备的服务赋形波束的方式中,由于N个候选赋形波束仅能覆盖小区内的某些方向,因而随着用户设备的移动,用户设备可能会超出此N个赋形波束的覆盖范围。那么,用户设备在对该N个赋形波束下的CSI-RS进行信道质量测量时,N个CSI-RS的波束质量都较差,均无法满足信号传输的需求,从而导致用户设备无法筛选出波束质量较好的赋形波束并上报给网络设备,导致通信链路传输的失败。
为了解决现有技术中存在的、由于用户设备的移动而导致的通信链路传输失败的问题,本申请提供一种信道质量信息的上报方法及装置。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。
下面首先介绍一下本申请的应用场景:在如图1所示的无线通信系统中,在下行传输过程中,网络设备在多个候选赋形波束下向用户设备发送参考信号,用户设备对网络设备发送的参考信号进行信道质量测量,并基于信道质量测量的结果,从多个候选赋形波束中选择一个或多个波束质量较优的赋形波束,并通过上行传输过程将选择的一个或多个赋形波束上报给网络设备。
本申请实施例中的网络设备可以是全球移动通信系统(Global System for Mobile Communications,GSM)或码分多址接入(Code Division Multiple Access,CDMA)中的网络设备(BTS,Base Transceiver Station),也可以是带宽码分多址接入(Wide-band Code Division Multiple Access,WCDMA)中的网络设备(NodeB),还可以是LTE中的演进型网络设备(evolutional Node B,eNB或e-NodeB),本申请实施例中并不限定。
本申请实施例中的用户设备可以是向用户提供语音和/或数据连通性的设备,对应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。用户设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,用户设备可以是移动终端,如移动电话(或称为“蜂窝”电话)和对应移动终端的计算机,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(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。用户设备也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station),移动站(Mobile Station)、 移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)或用户装备(User Equipment),本申请实施例中并不限定。
为了使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施例作进一步地详细描述。
参见图2,为本申请实施例提供的一种信道质量信息的上报方法的流程示意图。
S201:网络设备在第一参考信号资源上向用户设备发送P1个第一参考信号,并在第二参考信号资源上向用户设备发送P2个第二参考信号。
其中,P1≥1,P2≥1。
在S201中,第一参考信号资源对应了多个赋形波束,其中每个赋形波束的方向不同。网络设备在第一参考信号资源上向用户设备发送P1个第一参考信号,即在P1个不同的波束方向上向用户设备发送第一参考信号。同样地,第二参考信号资源也对应了多个赋形波束,其中每个赋形波束的方向不同。网络设备在第二参考信号资源上向用户设备发送P2个第二参考信号,即在P2个不同的波束方向上向用户设备发送第二参考信号。
本申请实施例中,采用波束赋形技术进行传输的参考信号包含小区特定的参考信号和用户特定的参考信号。其中,小区特定的参考信号可覆盖小区内的所有方向,而用户特定的参考信号仅能覆盖小区内的特定方向。即,小区内的所有用户设备或一组用户设备均可接收到小区特定的参考信号,而只有位于小区内特定方向的用户设备才可接收到用户特定的参考信号。示例性地,小区特定的参考信号可以是SS block中的某个信道或信号,如主同步信号(Primary Synchronization Signal,简称:PSS)或辅同步信号(Secondary Synchronization Signal,简称:SSS),用户特定的参考信号可以是CSI-RS或解调参考信号(Demodulation Reference Signal,DMRS),这里不做限定。
在S201中,第一参考信号可以是用户特定的参考信号,第二参考信号可以是小区特定的参考信号。当第一参考信号为用户特定的参考信号、第二参考信号为小区特定的参考信号时,位于小区内特定方向的用户设备可接收到第一参考信号、小区内的所有用户设备或一组用户设备均可接收到第二参考信号。
S202:用户设备对接收到的第一参考信号和第二参考信号进行信道质量测量。
其中,用户设备在对第一参考信号进行信道质量测量时,对接收到的P1个第一参考信号均进行信道质量测量;用户设备在对第二参考信号进行信道质量测量时,对接收到的P2个第二参考信号均进行信道质量测量。
用户设备对P1个第一参考信号进行信道质量测量,相当于用户设备对P1个第一参考信号中的每个第一参考信号对应的候选赋形波束进行波束质量测量,基于对P1个第一参考信号的信道质量测量结果,用户设备可对网络设备发送P1个第一参考信号时所基于的P1个候选赋形波束的波束质量做出判断;同样地,用户设备对P2个第二参考信号进行信道质量测量,相当于用户设备对P2个第二参考信号中的每个第二参考信号对应的候选赋形波束进行波束质量测量,基于对P2个第二参考信号的信道质量测量结果,用户设备可对网络设备发送P2个第二参考信号时所基于的P2个候选赋形波束的波束质量做出判断。
S203:用户设备向网络设备上报M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,并上报M个参考信号资源索引对应的参考信号类型或参考信号资源集 合的索引。其中,M≥1。
其中,信道质量信息包括以下信息中的至少一种:赋形波束的参考信号接收功率;赋形波束的参考信号接收质量。此外,信道质量信息还可以包含信道状态信息(Channel State Information,CSI),比如秩指示(Rank Indication,RI)、信道质量指示(Channel Quality Indication,CQI)和预编码矩阵指示(Precoding Matrix Indication,PMI)等。
用户设备向网络设备上报M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,以及M个参考信号资源索引对应的参考信号类型或参考信号资源集合的索引,即用户设备根据对P1个第一参考信号和P2个第二参考信号的信道质量测量结果,从(P1个第一参考信号对应的)P1个候选赋形波束和(P2个第二参考信号对应的)P2个候选赋形波束中选择了M个波束质量较优的赋形波束并上报给网络设备。
用户设备在选择M个赋形波束时,可以根据P1个第一参考信号的信道质量信息以及P2个第二参考信号的信道质量信息,选择P1个候选赋形波束中波束质量较优的赋形波束和/或P2个(P1个第一参考信号对应的)赋形波束中波束质量较优的赋形波束。比如,若用户设备从P1个候选赋形波束中选择M个赋形波束,且上报的信道质量信息中包含RSRP,那么用户设备可以从P1个候选赋形波束中选择RSRP较大的M个赋形波束。再比如,若用户设备从P1个候选赋形波束和P2个候选赋形波束中选择M个赋形波束,且上报的信道质量信息中包含RSRP,那么用户设备可以从P1个候选赋形波束中选择RSRP较大的M1个赋形波束,再从P2个候选赋形波束中选择RSRP较大的M2个赋形波束,其中,1≤M1≤P1,1≤M2≤P2,M=M1+M2,也就是说,M个赋形波束可看作是M1个赋形波束和M2个赋形波束构成的集合。
S203中,M个参考信号资源索引对应的参考信号类型可以是第一参考信号和/或第二参考信号,M个参考信号资源索引对应的参考信号资源集合的索引可以是第一参考信号资源集合的索引和/或第二参考信号资源集合的索引。以用户设备上报M个参考信号资源索引对应的参考信号类型为例,当M个参考信号资源索引对应的参考信号类型为第一参考信号时,即代表用户设备从P1个候选赋形波束中选择了M个波束质量较优的赋形波束并上报给网络设备;当M个参考信号资源索引对应的参考信号类型为第二参考信号时,即代表用户设备从P2个候选赋形波束中选择了M个波束质量较优的赋形波束并上报给网络设备;当M个参考信号资源索引对应的参考信号类型为第一参考信号和第二参考信号时,即代表用户设备从P1个候选赋形波束中选择了M1个波束质量较优的赋形波束,并从P2个候选赋形波束中选择了M2个波束质量较优的赋形波束,M1+M2=M,然后并将选择的M个赋形波束上报给网络设备。
本申请实施例中,用户设备接收到网络设备发送的P1个第一参考信号和P2个第二参考信号,因而用户设备在从(P1个第一参考信号对应的)P1个候选赋形波束和/或(P2个第二参考信号对应的)P2个候选赋形波束中选择M个赋形波束后,在上报M个参考信号资源索引对应的信道质量信息时,需要通过一种方式向网络设备指示用户设备选择的M个赋形波束具体是哪一个或哪几个赋形波束:网络设备通过用户设备上报的M个参考信号资源索引对应的参考信号类型或参考信号资源集合的索引,可确定该M个赋形波束是从P1个候选赋形波束中选择出来的,还是从P2个候选赋形波束中选择出来的,又或者是从P1个候选赋形波束和P2个候选赋形波束中选择出来的;再通过用户设备上报的M个参考信号资源索引,即可索引到P1个候选赋形波束中的M个赋形波束,或者索引到P2个候选 赋形波束中的M个赋形波束,亦或是索引到P1个候选赋形波束中的M1个赋形波束以及P2个候选赋形波束中的M2个赋形波束,1≤M1≤P1,1≤M2≤P2,M=M1+M2。
比如,若用户设备在S203中向网络设备上报的M个参考信号资源索引对应的参考信号类型为第一参考信号,那么网络设备可确定M个赋形波束是从P1个候选赋形波束中选择出来的;进一步地,网络设备通过用户设备上报的M个参考信号资源索引,即可索引到P1个候选赋形波束中的M个赋形波束。
进一步地,网络设备可根据用户设备上报的M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,选择信道质量较优的一个参考信号,并将该信道质量较优的参考信号对应的赋形波束配置为该用户设备的服务赋形波束。
S203中,用户设备可通过物理上行控制信道(Physical Uplink Control CHannel,PUCCH)或者通过物理上行共享信道(Physical Uplink SharedCHannel,PUSCH)向网络设备上报M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,并上报M个参考信号资源索引对应的参考信号类型或参考信号资源集合的索引。
在图2所示的信道质量信息的上报方法中,由于用户设备对网络设备发送的P1个第一参考信号以及P2个第二参考信号进行信道质量测量,根据信道质量测量的结果选择上报M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,并上报M个参考信号资源索引对应的参考信号类型或参考信号资源集合的索引。因而,网络设备可根据用户设备上报的如上信息,确定用户设备从(P1个第一参考信号对应的)P1个候选赋形波束和/或(P2个第二参考信号对应的)P2个候选赋形波束中选择的M个赋形波束具体是哪一个或哪几个赋形波束,进而将M个赋形波束中的一个赋形波束作为该用户设备的服务赋形波束,在后续进行下行传输时,在该服务赋形波束下向用户设备发送下行信号,从而通过较大的天线增益来补偿信号(尤其是高频信号)传播过程中的传播损耗。
此外,在图2所示方法中,用户设备基于第一参考信号和第二参考信号两种类型的参考信号进行信道质量信息上报,与现有技术中仅基于CSI-RS进行信道质量信息上报的方案相比,当用户设备移动到某类参考信号(第一参考信号或第二参考信号)的覆盖范围之外时,用户设备仍可基于另一类参考信号(第二参考信号或第一参考信号)选择并上报M个波束质量较优的赋形波束。因此,采用图2所示的方法,在用户设备发生移动时,用户设备仍可筛选并上报波束质量较优的赋形波束,从而避免通信链路传输失败。
特别地,当第一参考信号为用户特定的参考信号、第二参考信号为小区特定的参考信号时,由于小区特定的参考信号能够覆盖小区内的所有方向,因而无论用户设备移动到小区内的哪个方向,用户设备均可以从(P2个第二参考信号对应的)P2个候选赋形波束中筛选并上报M个波束质量较优的赋形波束,从而避免通信链路传输失败。
基于以上对本申请实施例中的信道质量信息上报方法的介绍可知,本申请实施例中,用户设备向网络设备上报M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,并上报M个参考信号资源索引对应的参考信号类型或参考信号资源集合的索引的方式有两种:
第一种,当第一参考信号对应的信道质量与第二参考信号对应的信道质量之差大于等于第一门限值时,用户设备从P1个第一参考信号中选择M个第一参考信号,上报M个第一参考信号资源索引及M个第一参考信号资源索引对应的信道质量信息,并上报M个第 一参考信号的参考信号类型或参考信号资源集合的索引。这里,第一门限值为大于或等于0的实数。
或者,当第二参考信号对应的信道质量与第一参考信号对应的信道质量之差大于等于第二门限值时,用户设备从P2个第二参考信号中选择M个第二参考信号,上报M个第二参考信号资源索引及M个第二参考信号资源索引对应的信道质量信息,并上报M个第二参考信号的参考信号类型或参考信号资源集合的索引。这里,第二门限值为大于或等于0的实数。
第二种,用户设备从P1个第一参考信号中选择M1个第一参考信号和从P2个第二参考信号选择M2个第二参考信号,1≤M1≤P1,1≤M2≤P2,M=M1+M2;然后,用户设备向网络设备上报如下信息:M1个第一参考信号资源索引及M1个第一参考信号资源索引对应的信道质量信息;M1个第一参考信号资源索引对应的参考信号类型或参考信号资源集合的索引;M2个第二参考信号资源索引及M2个第二参考信号资源索引对应的信道质量信息;M2个第二参考信号资源索引对应的参考信号类型或参考信号资源集合的索引。
下面对这两种上报方式分别进行详细介绍。
第一种上报方式
在第一种上报方式中,用户设备需从(P1个第一参考信号对应的)P1个候选赋形波束或(P2个第二参考信号对应的)P2个候选赋形波束中选择M个赋形波束,具体可通过如下方式实现:当第一参考信号对应的信道质量与第二参考信号对应的信道质量之差大于第一门限值(比如3dB)时,用户设备从P1个候选赋形波束中选择M个赋形波束;或者,当第二参考信号对应的信道质量与第一参考信号对应的信道质量之差大于第二门限值时,用户设备从P2个候选赋形波束中选择M个赋形波束。
其中,该第一门限值和第二门限值可以根据具体需求灵活配置,第一门限值和第二门限值可以相同,也可以不同。
采用第一种上报方式,用户设备仅上报基于一类参考信号的信道质量测量结果,因而可以减小用户设备的上报开销。
此外,用户设备还可向网络设备上报用户设备的功率控制所基于的参考信号类型或参考信号资源集合索引。那么,网络设备在获知用户设备的功率控制所基于的参考信号类型或参考信号资源集合索引后,可进一步对用户设备的发射功率进行控制。
第二种上报方式
在第二种上报方式中,用户设备需从(P1个第一参考信号对应的)P1个候选赋形波束和(P2个第二参考信号对应的)P2个候选赋形波束中选择M个赋形波束,具体可通过如下方式实现:用户设备根据网络设备的配置,从P1个候选赋形波束中选择M1个赋形波束,并从P2个候选赋形波束中选择M2个赋形波束,其中,1≤M1≤P1,1≤M2≤P2,M=M1+M2。
采用第二种上报方式,用户设备可基于网络设备的配置对两种类型的参考信号的信道质量测量结果均进行上报,从而满足网络设备的配置需求。
在采用第二种上报方式时,由于需要上报两种类型的参考信号的信道质量测量结果,因而为了减小用户设备的上报开销,可设置用户设备在上报两种类型的信道质量测量结果时,基于统一的上报格式进行上报。
一种统一上报格式的具体方式可以是,统一第一参考信号资源索引和第二参考信号资 源索引的上报比特数。
示例性地,假设第一参考信号为用户特定的参考信号、第二参考信号为小区特定的参考信号,那么,第一参考信号支持的最大候选赋形波束数目是固定的,通常为8;而第二参考信号支持的最大候选赋形波束数目是随着第二参考信号的载频动态变化的,通常,当第二参考信号的载频小于6GHz时,第二参考信号支持的最大候选赋形波束数目是8,当第二参考信号的载频大于6GHz时,第二参考信号支持的最大候选赋形波束数目是64。
也就是说,对于第一参考信号来说,当第一参考信号资源索引为3比特时,即可通过该第一参考信号资源索引来索引到8(2 3)个候选赋形波束中的每一个候选赋形波束。对于第二参考信号来说,若第二参考信号的载频小于6GHz,那么当第二参考信号资源索引为3比特时,即可通过该第二参考信号资源索引来索引到8(2 3)个候选赋形波束中的每一个候选赋形波束;若第二参考信号的载频大于6GHz,那么当第二参考信号资源索引为6比特时,即可通过该第二参考信号资源索引来索引到64(2 6)个候选赋形波束中的每一个候选赋形波束。由此可以看出,若第二参考信号的载频大于6GHz,第一参考信号资源索引的上报比特数(3)与第二参考信号资源索引的上报比特数(6)是不同的。
通过如上示例可以发现,若采用第二种上报方式,会出现第一参考信号资源索引的上报比特数和第二参考信号资源索引的上报比特数不同的情况,因此,本申请中,可以通过如下两种方案统一第一参考信号资源索引和第二参考信号资源索引的上报比特数。
方案一
方案一的具体方式如下:网络设备向用户设备发送第一通知消息,第一通知消息用于指示用户设备接收第一参考信号的第一测量时间窗;然后,用户设备在该第一测量时间窗内对接收到的第一参考信号进行信道质量测量;或者,网络设备向用户设备发送第二通知消息,第二通知消息用于指示用户设备接收第二参考信号的第二测量时间窗;然后,用户设备在该第二测量时间窗内对接收到的第二参考信号进行信道质量测量。
当网络设备可通过第一通知消息指示用户设备接收第一参考信号的第一测量时间窗时,用户设备可在第一测量时间窗下接收第一参考信号,使得在第一测量时间窗下接收到的P1个第一参考信号的数量与P2个第二参考信号的数量相同或相近,那么此时,第一参考信号资源索引的上报比特数为可以与第二参考信号资源索引的上报比特数相同,比如,P1=P2=64,那么当第一参考信号资源索引和第二参考信号资源索引均为6比特时,即可通过该第一参考信号资源索引来索引到(P1个第一参考信号对应的)64(2 6)个候选赋形波束中的每一个候选赋形波束,也可通过该第二参考信号资源索引来索引(P2个第二参考信号对应的)到64(2 6)个候选赋形波束中的每一个候选赋形波束。
当网络设备可通过第二通知消息指示用户设备接收第二参考信号的第二测量时间窗时,用户设备可在第二测量时间窗下接收第二参考信号,使得在第二测量时间窗下接收到的P2个第二参考信号的数量与P1个第一参考信号的数量相同或相近,那么此时,第一参考信号资源索引的上报比特数为可以与第二参考信号资源索引的上报比特数相同,比如,P1=P2=8,那么当第一参考信号资源索引和第二参考信号资源索引均为3比特时,即可通过该第一参考信号资源索引来索引到(P1个第一参考信号对应的)8(2 3)个候选赋形波束中的每一个候选赋形波束,也可通过该第二参考信号资源索引来索引到(P2个第二参考信号对应的)8(2 3)个候选赋形波束中的每一个候选赋形波束。
示例性地,若第一参考信号为用户特定的参考信号、第二参考信号为小区特定的参考 信号,且第二参考信号的载频大于6GHz,那么,第一参考信号支持的最大候选赋形波束数目是8个,第二参考信号支持的最大候选赋形波束数目是64个。此时,网络设备可通过第一通知消息指示用户设备接收第一参考信号的第一测量时间窗,用户设备在该第一测量时间窗下对网络设备分8次发送的第一参考信号进行信道质量测量,从而使得8*8=64,那么此时,第一参考信号资源索引的上报比特数为6,第二参考信号资源索引的上报比特数也为6。
采用方案一来统一第一参考信号资源索引和第二参考信号资源索引的上报比特数,可减小用户设备的上报开销。
方案二
方案二的具体方式如下:网络设备向用户设备发送第三通知消息,该第三通知消息用于指示用户设备在对第二参考信号进行信道质量测量时的测量子集,该测量子集包含P2个第二参考信号中的部分第二参考信号;那么,用户设备在对第二参考信号进行信道质量测量时,可仅对测量子集进行信道质量测量。
当第一参考信号为用户特定的参考信号、第二参考信号为小区特定的参考信号时,第一参考信号资源索引的上报比特数通常小于第二参考信号资源索引的上报比特数,因而若要统一第一参考信号资源索引和第二参考信号资源索引的上报比特数,网络设备可指示用户设备仅对接收到的P2个第二参考信号中的部分第二参考信号进行信道质量测量,从而进行信道质量测量的第二参考信号的数量与进行信道质量测量的第一参考信号的数量相同或相当,那么此时,第二参考信号资源索引的上报比特数为可以与第一参考信号资源索引的上报比特数相同,比如为3。
示例性地,若第一参考信号为用户特定的参考信号、第二参考信号为小区特定的参考信号,且第二参考信号的载频大于6GHz,那么,第一参考信号支持的最大候选赋形波束数目是8个,第二参考信号支持的最大候选赋形波束数目是64个。此时网络设备通过第三通知消息指示第二参考信号的测量子集,该测量子集中可包含8个第二参考信号。那么当第一参考信号资源索引和第二参考信号资源索引均为3比特时,即可通过该第一参考信号资源索引来索引到(8个第一参考信号对应的)8(2 3)个候选赋形波束中的每一个候选赋形波束,也可通过该第二参考信号资源索引来索引到(8个第二参考信号的测量子集对应的)8(2 3)个候选赋形波束中的每一个候选赋形波束。
采用方案二来统一第一参考信号资源索引和第二参考信号资源索引的上报比特数,可减小用户设备的上报开销。
在第二种上报方式中,网络设备还可向用户设备发送第四通知消息,该第四通知消息用于指示用户设备进行功率控制时所基于的参考信号类型或参考信号资源集合的索引,从而用于用户设备在向网络设备发送上行信号时根据该参考信号类型或参考信号资源集合的索引设置或调整发射功率。
此外,在第二种上报方式中,网络设备还可向用户设备发送指示信息,该指示信息用于指示网络设备配置的QCL假设指示对应的参考信号类型或参考信号资源集合的索引。
其中,QCL假设指示可用来辅助描述用户设备的接收侧波束赋形信息以及用户设备的接收流程。当QCL假设指示对应的参考信号类型为用户特定的参考信号时,用户设备在后续接收数据的过程中基于上报的M1个第一参考信号对应的赋形波束进行数据接收,否则用户设备基于上报的M2个第二参考信号对应的赋形波束进行数据接收。
其中,QCL假设可包括一些空间特性参数,诸如水平向出发角(Azimuth angle of Departure,AoD)、垂直向出发角(Zenith angle of Departure,ZoD)、水平向角度扩展(Azimuth angle spread of Departure,ASD)、垂直向角度扩展(Zenith angle spread of Departure,ZSD)等出发角相关参数,或者诸如水平向到达角(Azimuth angle of Arrival,AoA)、垂直向出发角(Zenith angle of Arrival,ZoA)、水平向角度扩展(Azimuth angle spread of Arrival,ASA)、垂直向角度扩展(Zenith angle spread of Arrival,ZSA)等到达角相关参数。这些空间特性参数描述了网络设备发送P1个第一参考信号和P2个第二参考信号的天线端口间的空间信道特性,从而可辅助描述用户设备的接收侧波束赋形信息以及用户设备的接收流程。可选地,该QCL假设包括的空间特性参数也可以为除上述参数外的其他参数,本申请实施例中对此不做限定。
此外,为了节省网络设备对用户设备的QCL假设指示的开销,网络设备发送给用户设备的QCL假设指示中可限定:网络设备发送给用户设备的QCL假设指示所对应的有效时间窗。用户设备在S204中上报的M个赋形波束对中的一个是满足QCL假设的。
以上是对本申请实施例中的波束质量信息的两种上报方式的介绍。在采用本申请实施例提供的信道质量信息的上报方法时,可依据实际情况对上述两种上报方式进行选择。
此外,本申请实施例中,用户设备上报M个参考信号资源索引对应的信道质量信息时,可采用分组上报的方式:用户设备根据M个参考信号资源索引对应的信道质量信息,上报L个参考信号资源索引组的信道质量信息,L≥1。
其中,L个参考信号资源索引组中每个参考信号资源索引组包含的参考信号资源索引共同构成M个参考信号资源索引,L个参考信号资源索引组对应的波束组类型为第一类型或第二类型,波束组类型为第一类型的参考信号资源索引组中的每个赋形波束可被用户设备同时接收到,波束组类型为第二类型的参考信号资源索引组中的每个赋形波束不可被用户设备同时接收到。
具体地,当M个参考信号中属于同一个panel的参考信号的信道质量之差的最大值小于第三门限值时,用户设备上报的L个参考信号资源索引组对应的波束组类型为第二类型,L个参考信号资源索引组中每个参考信号资源索引组的RSRP为该参考信号资源索引组包含的所有参考信号的RSRP的平均值;当M个参考信号中属于每个panel的参考信号的最优信道质量之差的最大值小于第四门限值时,用户设备上报的L个参考信号资源索引组对应的波束组类型为第一类型,L个参考信号资源索引组中每个参考信号资源索引组的RSRP为该参考信号资源索引组包含的所有参考信号的RSRP的平均值和/或最大值。
此外,当用户设备上报的L个参考信号资源索引组对应的波束组类型为第一类型时,对于每个参考信号资源索引组,用户设备除了可上报该组包含的所有参考信号的RSRP的最大值以外,还可上报该组中其他参考信号的RSRP与该最大值的差值的步进索引值,以及该步进索引值对应的参考信号的数量。比如,该参考信号资源索引组包含的所有参考信号的RSRP的最大值为-46dB,那么用户设备还可上报如下信息:index=0的参考信号的数量为2、index=1的参考信号的数量为1,index=2的参考信号的数量为3,index=3的参考信号的数量为1。其中,index=0代表该参考信号的RSRP与最大值-46dB的差值为-1dB,index=1代表该参考信号的RSRP与最大值-46dB的差值为-2dB,index=2代表该参考信号的RSRP与最大值-46dB的差值为-3dB,index=3代表该参考信号的RSRP与最大值-46dB 的差值为-4dB。其中,index即为步进索引值,2、1、3、1即为每个步进索引值对应的参考信号的数量。
需要说明的是,用户设备在上报M个参考信号资源索引对应的信道质量信息时,可采用上述将每个参考信号资源索引对应的信道质量信息进行分组上报的方式,也可分别上报M个参考信号资源索引中每个参考信号资源索引对应的信道质量信息。
基于以上实施例,本申请还提供一种信道质量信息的上报装置,该信道质量信息的上报装置可用于执行图2所示的信道质量信息的上报方法中用户设备所执行的操作。参见图3,该信道质量信息的上报装置300包括接收单元301、处理单元302和发送单元303。其中,
接收单元301用于接收网络设备在第一参考信号资源上发送的P1个第一参考信号以及网络设备在第二参考信号资源上发送的P2个第二参考信号,P1≥1,P2≥1。
处理单元302用于对第一参考信号和第二参考信号进行信道质量测量。
发送单元303用于向网络设备上报M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,并上报M个参考信号资源索引对应的参考信号类型或参考信号资源集合的索引,M≥1。

需要说明的是,本申请中对单元的划分是示意性的,仅仅为一种逻辑功能划分,实际实现时可以有另外的划分方式。本申请实施例中的各功能单元可以集成在一个处理单元中,也可以是各个单元单独物理存在,也可以两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现,也可以采用软件功能单元的形式实现。
采用图3所示的信道质量信息的上报装置300,由于处理单元302对网络设备发送的P1个第一参考信号以及P2个第二参考信号进行信道质量测量,发送单元303根据信道质量测量的结果选择上报M个参考信号资源索引及M个参考信号资源索引对应的信道质量信息,并上报M个参考信号资源索引对应的参考信号类型或参考信号资源集合的索引。因而,网络设备可根据信道质量信息的上报装置300上报的如上信息,确定信道质量信息的上报装置300从(P1个第一参考信号对应的)P1个候选赋形波束和/或(P2个第二参考信号对应的)P2个候选赋形波束中选择的M个赋形波束具体是哪一个或哪几个赋形波束,进而将M个赋形波束中的一个赋形波束作为该用户设备的服务赋形波束,在后续进行下行传输时,在该服务赋形波束下向信道质量信息的上报装置300发送下行信号,从而通过较大的天线增益来补偿信号(尤其是高频信号)传播过程中的传播损耗。
此外,信道质量信息的上报装置300基于第一参考信号和第二参考信号两种类型的参考信号进行信道质量信息上报,与现有技术中仅基于CSI-RS进行信道质量信息上报的方案相比,当信道质量信息的上报装置300移动到某类参考信号(第一参考信号或第二参考 信号)的覆盖范围之外时,信道质量信息的上报装置300仍可基于另一类参考信号(第二参考信号或第一参考信号)选择并上报M个波束质量较优的赋形波束。因此,采用信道质量信息的上报装置300,在信道质量信息的上报装置300发生移动时,信道质量信息的上报装置300仍可筛选并上报波束质量较优的赋形波束,从而避免通信链路传输失败。
特别地,当第一参考信号为用户特定的参考信号、第二参考信号为小区特定的参考信号时,由于小区特定的参考信号能够覆盖小区内的所有方向,因而无论信道质量信息的上报装置300移动到小区内的哪个方向,信道质量信息的上报装置300均可以从(P2个第二参考信号对应的)P2个候选赋形波束中筛选并上报M个波束质量较优的赋形波束,从而避免通信链路传输失败。

特别地,当第一参考信号为用户特定的参考信号、第二参考信号为小区特定的参考信号时,由于小区特定的参考信号能够覆盖小区内的所有方向,因而无论用户设备移动到小区内的哪个方向,用户设备均可以从(P2个第二参考信号对应的)P2个候选赋形波束中筛选并上报M个波束质量较优的赋形波束,从而避免通信链路传输失败。
