Description
本申请实施例涉及通信领域,并且更具体地,涉及一种信息指示的方法、网络设备和终端设备。
现有长期演进系统(Long Term Evolution,简称“LTE”)及LTE-A(LTE Advanced)技术主要工作在低频段,由于其频段强穿透性较强,可有用对抗数据传输过程中的路径损耗及阴影衰落,覆盖范围广。因此该频段射频通道与天线阵子之间通常为一一对应的关系,或采用宽波束模拟加权实现射频通道与天线阵子之间的映射关系,从而可认为每个射频通道出来的信号到达接收端时具用相似的信道大尺度特性。
毫米波频段由于其频谱资源丰富,成为5G技术的主要工作频段之一。使用毫米波频段时,由于其频段在数据传输过程中的路径损耗大,抗衰落性能差,通过需要在射频通过与天线阵子之间采用窄波束模拟加权处理,且为了实现小区覆盖、降低实现成本,模拟权值个数往往远大于射频通道个数。同一射频通道在不同时刻采用的模拟权值可动态切换。由于不同的窄波束在传输过程中所经历的信道影响具有较大差别。因此,对于采用不同窄波束模拟权值的射频通道在接收端不能认为其较有相似的信道大尺度特性,即针对不同窄波束模拟加权的射频端口需要分别做信道估计。
网络设备通常基于导频信号的信道测量与反馈实时调度服务用户。因此,导频测量的时效性及准确性直接影响系统的频谱效率和用户体验。但现有LTE及LTE-A技术在进行导频测量时通常假设所有射频通道之间具用相似的信道大尺度特性,联合进行信道测量与估计,现有技术无法实现不同模拟波束的信道测量与上报,从而不支持网络设备基于多个不同模拟波束的多输入多输出(Multiple-Input Multiple-Output,简称“MIMO”)传输,严重影响了网络设备调度的灵活性,从而影响了整个系统的频谱效率及用户体验。

图5B示出了根据本申请实施例的信息指示的方法的再一示意性流程图。
当前,现有RAN1会议已同意CSI获取和波束管理的配置架构,即为一个终端配置一个信道状态信息测量设置(CSI measurement setting),其中一个CSI measurement setting包含一个或多个链路(links);每个links对应一个信道状态信息上报设置(CSI reporting setting)和一个资源设置(Resource setting),其中每个Resource setting包含一个或多个信道状态信息参考信号资源集合(CSI-RS resource set(s)),每个CSI-RS resource set(s)包含一个或多个信道状态信息参考信号资源CSI-RS resource(s)。
也即是说,一个CSI reporting setting会对应一个或多个CSI-RS resource(s),在不同的场景,基于多个CSI-RS resource(s)获取CSI测量及上报内容的需求也有所不同。而现有的LTE-A协议中,针对beamformed CSI-RS测量配置,一个CSI测量配置会包含多个NZP CSI-RS资源配置,但系统默认只从多个NZP CSI-RS资源配置内选择一个NZP CSI-RS资源配置,并基于选取的NZP CSI-RS资源实现CSI上报内容的测量、计算及反馈。这种现有的实现方式不适合新空口(new radio,NR)技术中讨论的基于通用CSI配置架构的针对不同场景下的需求实现。
本发明实施例目的在于为NR提供一套通用的CSI测量或波束管理配置架构实现不同场景下的CSI测量需求。本发明实施例的核心思想是预定义一套CSI测量及反馈的规则,通过一定的方式将规则显式或隐式地通知终端设备,用于终端设备根据所述规则来进行CSI测量。
比如,一种可能的应用场景一是:基于低频段(频率小于6GHz)的CSI测量及反馈
针对传统的低频段的移动通信业务,网络设备可以通过一个或多个CSI-RS资源或者CSI-RS资源集合将导频(等同于本说明书中的参考信号,仅名称不同而已)配置给终端设备,终端设备需要聚合一个或多个CSI-RS资源或者聚合所有的CSI-RS的端口进行CSI测量,并将测量结果反馈给网络设备。
示例性地,假设网络设备为终端设备配置了CSI-RS资源0和CSI-RS资源1(或者配置了CSI-RS资源集合0和CSI-RS资源集合1),其中,每一个CSI-RS资源或CSI-RS资源集合包含两个端口的配置信息,此时,终端设备需要聚合处理CSI-RS资源0和CSI-RS资源1的测量结果,并基于聚合后的信道信息生成CSI反馈信息,以PMI为例进行说明终端设备如何聚合CSI-RS资源0和CSI-RS资源1的测量结果。
A、首先,终端设备分别获取CSI-RS资源0和CSI-RS资源1的信道矩阵,如下所示:
B,终端设备合并CSI-RS资源0和CSI-RS资源1的信道矩阵:
C,终端设备基于合并的H矩阵获取PMI,具体的获取过程请参照现有技术的说明,这里不在赘述。
应理解,在场景一中,终端设备需要聚合所有的CSI-RS资源,并基于聚合后的所有CSI-RS资源反馈CSI信息。
再比如,另一种可能的应用场景二是:基于模拟波束的CSI聚合测量及反馈
在波束管理中,网络设备为终端设备配置了N个模拟波束,终端设备基于配置的N个模拟波束实现后续的CSI测量及反馈。
示例性地,假设网络设备只有两个射频端口,在波束管理中,网络设备为终端设备配置了2个模拟波束,那么2个射频端口与2个模拟波束之间存在4种对应关系,例如,端口1对应波束1,端口1对应波束2,依次类推。网络设备为终端设备配置了两个CSI-RS资源,比如CSI-RS资源0和CSI-RS资源1,每个CSI-RS资源包含两个端口,对应一个模拟波束。终端设备在CSI测量时需要遍历所有的射频端口与模拟波束的所有组合,如下所示:
其中,H1指第一个射频端口承载模拟波束2,第二个射频端口承载模拟波束2时,端终所测量到的收发天线之间的信道矩阵;
H2指第一个射频端口承载模拟波束2,第二个射频端口承载模拟波束3时,端终所测量到的收发天线之间的信道矩阵;指第一个射频端口承载模拟波束3,第二个射频端口承载模拟波束3时,端终
H3所测量到的收发天线之间的信道矩阵;
H4指第一个射频端口承载模拟波束3,第二个射频端口承载模拟波束2时,端终所测量到的收发天线之间的信道矩阵;
终端设备分别计算这四种信道矩阵所对应的信道质量,比如CQI,PMI,RI,RSRP,RSRQ等信息,从中选取最强的信道质量及相应的射频端口和模拟波束的
关联信道反馈给网络设备。其中,射频端口和模拟波束的关联信道的具体指示方式包括由CSI-RS资源索引来指示对应的模拟波束。
再比如,另一种可能的应用场景三是:多传输接收点(Transmission Reception point,TRP)协作传输的聚合测量及反馈
针对多TRP协作传输场景,假设不同的TRP的CSI-RS资源通过多个CSI-RS资源或资源集合配置给终端设备,需要根据终端设备的当前的数据传输模式里选取相应的CSI测量方法。
示例性地,当终端设备选取一个TRP进行数据传输时,则在CSI测量时需要将服务TRP所对应的一个或多个CSI-RS资源用于信道测量,将其他协作TRP所对应的一个或多个CSI-RS资源用于干扰测量;当终端设备选取多个TRP做联合数据传输时,则在CSI测量时需要将多个服务TRP所对应的一个或多个CSI-RS资源用于信道测量,将其他协作TRP所对应的一个或多个CSI-RS资源用于干扰测量。一种具体的实现方式为:在CSI-RS测量配置内配置每个CSI-RS资源或者CSI-RS集合的测量属性,其中,测量属性包括信道测量和干扰测量。终端设备根据每个CSI-RS资源或者CSI-RS资源集合的测量属性实现CSI的测量及反馈。
针对上述提到的三种可能的应用场景,本发明实施例提供一种CSI测量的方法,所述方法包括:
S501,网络设备生成控制信息,所述控制信息包括用于指示多个CSI-RS资源的测量方法;
S502,将所述控制信息发送给终端设备;
S502,终端设备接收所述控制信息,并根据所述指示的多个CSI-RS资源的测量方法,进行相应的测量。
可选地,S501中的控制信息可以携带在链路link的配置消息发送给终端设备,还可以携带在上报设置的配置消息中发送给终端设备,还可以携带在波束管理的配置消息中发送给终端设备,还可以携带在CSI-RS resource的配置消息中发送给终端设备。
可选地,当所述控制信息为第一数值时,用于指示终端设备基于网络设备配置的多个CSI-RS资源的所有端口联合测量CSI并反馈。
可选地,当所述控制信息为第二数值时,用于指示终端设备基于配置的多个CSI-RS资源的所有端口遍历选取最强的射频端口与模拟波束的关联结合测量CSI并反馈。
可选地,当所述控制信息为第三数值时,用于指示终端设备结合每个CSI-RS资源配置的测量属性(比如,信道测量、干扰测量)进行测量CSI并反馈。
示例性地,表5给出了一种具体的实现方式。
表5
在另一种可能的实现方式中,网络设备可以通过隐式的方式来指示多个CSI-RS资源的测量方法。比如,如表6所示,根据终端设备的传输模式与多个CSI-RS资源的测量方法的映射关系信息,终端设备通过获取传输模式信息,进而间接获取测量模式信息。
表6
终端设备的传输模式与终端设备的测量模式的映射关系信息可以由网络设备动态发送给终端设备,也可以预配置或者预存储在终端设备上。在该实现方式下,所述用于指示终端设备测量模式的信息为所述终端设备的传输模式信息。
该传输模式信息可以由网络设备通过信令发送给终端设备,也可以由终端设备自己获取。
图5C示出了根据本申请实施例的信息指示的方法的再一示意性流程图。
当前,现有RAN1会议已同意CSI获取和波束管理的配置架构,即为一个终端配置一个信道状态信息测量设置(CSI measurement setting),其中一个CSI measurement setting包含一个或多个链路(links);每个links对应一个信道状态信息上报设置(CSI reporting setting)和一个资源设置(Resource setting),其中每个Resource setting包含一个或多个信道状态信息参考信号资源集合(CSI-RS resource set(s)),每个CSI-RS resource set(s)包含一个或多个信道状态信息参考信号资源CSI-RS resource(s)。
也即是说,一个CSI reporting setting会对应一个或多个CSI-RS resource(s),在不同的场景,基于多个CSI-RS resource(s)获取CSI测量及上报内容的需求也有所不同。而现有的LTE-A协议中,针对beamformed CSI-RS测量配置,一个CSI测量配置会包含多个NZP CSI-RS资源配置,但系统默认只从多个NZP CSI-RS资源配置内选择一个NZP CSI-RS资源配置,并基于选取的NZP CSI-RS资源实现CSI上报内容的测量、计算及反馈。这种现有的实现方式不适合新空口(new radio,NR)技术中讨论的基于通用CSI配置架构的针对不同场景下的需求实现。
本发明实施例目的在于为NR提供一套通用的CSI测量或波束管理配置架构实现不同场景下的波束测量需求。本发明实施例的核心思想是预定义一套波束测量的规则,通过一定的方式将规则显式或隐式的通知终端设备,用于终端设备根据所述规则来进行波束测量。
比如,一种可能的场景一:网络设备终端设备需求的波束测量
当终端设备处于高速移动时,反馈空间相关性较低的多个波束给网络设备,以支持终端设备高速移动下的鲁棒性传输需求。而当终端设备处于低速移动时,反馈空间相关性较高的多个波束给网络设备,以支持闭环多用户MIMO,从而提升系统的数据传输速率。
再比如,另一种可能的场景二:基于多TRP协作的波束测量
基于多个TRP协作传输的场景中,数据传输方式分为三种方式,包括动态节点选择(动态节点选择是指只选择其中的一个TRP进行数据传输)、联合传输(联合传输是指选择多个TRP进行相同的数据传输)、非相干联合传输(非相干联合传输是指选择多个TRP进行不同的数据传输)。
如果不同TRP的多个CSI-RS资源或者集合配置给终端设备,并且只利用一个TRP进行数据传输,则波束获取的过程如下:
步骤1:终端设备基于多个CSI-RS资源或者集合的测量结果选取最好的服务TRP。
步骤2:基于选定的TRP以及所对应的CSI-RS资源,根据测量结果选取N个上报波束。
如果不同TRP的多个CSI-RS资源或者集合配置给终端设备,利用多个TRP进行数据传输时,对多个TRP所对应的所有CSI-RS资源或者资源集合进行测量并从中选取N个上报波束。
再比如,另一种可能的场景三:初始接入的波束测量
终端设备在初始接入时,网络设备没有任何终端设备的信息,无法指导终端设备如何选择上报波束。因此,需要终端设备自主决策选取N个波束测量上报,或者预定一种规则,例如选取相关性最低的N个波束进行测量并上报。
基于上述三种不同场景的需求,5G NR需要定义一种波束测量以及反馈的规则,该规则可以显示或隐式的方式指示给终端设备。本发明实施例提供一种波束反馈的方法,所述方法包括:
S510,网络设备生成控制信息,所述控制信息包括用于指示终端设备反馈波束的方法;
S512,将所述控制信息发送给终端设备;
S514,终端设备接收所述控制信息,并根据所述指示的反馈波束的方法,进行相应的反馈。
可选地,S501中的控制信息可以携带在测量配置measurement setting消息发送给终端设备,还可以携带在上报设置的配置消息中发送给终端设备,还可以携带在CSI-RS resource setting或者resource set或者resource的配置消息中发送给终端设备。
可选地,当所述控制信息为第一数值时,用于指示终端设备从所有CSI-RS资源配置中选取N个最强的波束进行测量,并上报测量结果,N大于等于1;
可选地,当所述控制信息为第二数值时,用于指示从某一个CSI-RS资源或CSI-RS资源集合内选取N个波束进行测量,并上报测量结果。
可选地,当所述控制信息为第三数值时,用于指示终端设备选取空间相关性强的波束上报。
可选地,当所述控制信息为第四数值时,用于指示终端设备选取空间相关性弱的波束上报。
可选地,当所述控制信息为第五数值时,用于指示终端设备自主决策上报波束的选取方法。
示例性地,表6给出了一种具体的实现方式。
表6
所述取值还可以为类型字段、ID编号、比特位图或者其他字段,并且所述取值没有先后之分以及相互间不存在必然的依赖关系。当表6中的第一列字段为类型时,可以理解为类型一对应从所有CSI-RS资源配置中选取N个最强的波束进行测量,并上报测量结果、类型二对应从某一个CSI-RS资源或CSI-RS资源集合内选取N个波束进行测量,并上报测量结果,依次类推,不再赘述。
除了上述显式的指示方法,还可以通过隐式的方式来指示波束反馈的方法,比如:
网络设备配置终端的传输模式与波束反馈的方法的映射关系,并给映射关系发送给终端设备。当终端获取自身的传输模式后,根据上述映射关系,可以获得波束反馈的方法。如表7所示:
表7
| 终端的传输模式 | 波束反馈的方法 |
| 第一传输模式 | 上报相关性较低的N个最强波束给网络设备 |
| 第二传输模式 | 上报相关性较高的N个最强波束给网络设备 |
其中,终端的传输模式可以为SFBC模式、CL-MIMO模式。
除了上述隐式指示的方法,终端设备还可以自主决策上报的波束。例如:当
前终端设备信道质量较差或处于高速移动时,上报相关性较低的N个最强波束给网络设备;当前终端设备信道质量较好或处于低速移动时,上报相关性较高的N个最强波束给网络设备;其中,具体决策规则可由网络设备通过其他消息指示给终端,或采用预先定义的默认规则。
基于RAN1#88次会议,接收端会对发送端的发送波束进行分组处理(下行时,接收端为终端设备,发送端为网络设备;上行时,接收端为网络设备,发送端为终端设备),上述描述的指示信息可以包括一个或者多个,用于指示组内或者组间或者组内与组间所选波束的特性。该指示信息可以为网络设备配置给UE,同时也可以为UE上报的时候携带该指示信息给网络设备。
