Description

通信方法、终端及网络设备
本申请要求于2017年06月16日提交中国专利局、申请号为201710459702.X、申请名称为“通信方法、终端及网络设备”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中。
技术领域
本申请涉及通信领域,并且更具体地,涉及通信方法、终端及网络设备。
背景技术
波束赋形是一种基于天线阵列的信号预处理技术,波束赋形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,从而能够获得明显的阵列增益。因此,波束赋形技术在扩大覆盖范围、改善边缘吞吐量以及干扰抑止等方面都有很大的优势。
在LTE通信系统中,网络设备可以通过使用波束赋性(beam forming)技术,提升下行传输时的覆盖,但在上行传输的过程中,LTE系统并不支持波束赋性技术,也就是说,终端在上行传输的过程中并不能使用不同的波束发送上行信号。随着技术的发展,为了提升在上行传输时的覆盖,在新无线(New Radio,NR)通信系统中,在终端侧也引入了波束赋性技术,也就是说,终端可以通过波束赋性技术提升下行传输时的覆盖,即通过不同的波束传输上行信号。
然而,在下行传输过程中,终端虽然可以通过不同的波束发送上行信道,但是终端只有特定的场景下,可以确定发送上行信道的波束。因此,亟需一种技术手段,帮助终端在大多数通信场景下确定发送上行信道的波束。

为便于理解下面对本申请中涉及到的一些名词做些说明。
本申请中,名词“网络”和“系统”经常交替使用,但本领域的技术人员可以理解其含义。 用户设备(User Equipment,UE)是一种具有通信功能的终端设备,也可以称为终端,可以包括具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备等。在不同的网络中用户设备可以叫做不同的名称,例如:终端,移动台,用户单元,站台,蜂窝电话,个人数字助理,无线调制解调器,无线通信设备,手持设备,膝上型电脑,无绳电话,无线本地环路台等。为描述方便,本申请中简称为用户设备UE或终端。网络设备可以是基站(base station,BS)、云网络中的无线接入设备或中继站等具有无线收发功能的设备。基站也可称为基站设备,是一种部署在无线接入网用以提供无线通信功能的设备。在不同的无线接入系统中基站的名称可能有所不同,例如在而在通用移动通讯系统(Universal Mobile Telecommunications System,UMTS)网络中基站称为节点B(NodeB),在LTE网络中的基站称为演进的节点B(evolved NodeB,eNB或者eNodeB),在未来5G系统中可以称为收发节点(Transmission Reception Point,TRP)网络节点或g节点B(g-NodeB,gNB)。本发明中的网络设备可以为具有网络设备功能的UE或终端,终端也可以是具有终端功能的网络设备,网络设备或终端设备还可以是具有中继功能的设备。
为了便于理解本申请实施例,下面简单介绍本申请实施例中涉及的空间准共址(Quasi-Co-Location,QCL)以及波束互易性的概念。
首先,本申请实施例中涉及的空间QCL关系是指信号的天线端口对应的信号中具有相同的参数,或者,空间QCL关系指的是终端可以根据一个天线端口的参数确定与所述天线端口具有空间QCL关系的一个天线端口的参数,或者,空间QCL关系指的是两个天线端口具有相同的参数,或者,空间QCL关系指的是两个天线端口具的参数差小于某阈值。其中,该参数可以为时延扩展,多普勒扩展,多普勒频移,平均时延,平均增益,到达角(Angle of arrival,AOA),平均AOA、AOA扩展,离开角(Angle of Departure,AOD),平均离开角AOD、AOD扩展,接收天线空间相关性参数,发送天线空间相关性参数,发送波束,接收波束,资源标识中的至少一个。所述波束包括以下至少一个,预编码,权值序号,波束序号。所述角度可以为不同维度的分解值,或不同维度分解值的组合。所述的天线端口为具有不同天线端口编号的天线端口,和/或具有相同天线端口号在不同时间和/或频率和/或码域资源内进行信息发送或接收的天线端口,和/或具有不同天线端口号在不同时间和/或频率和/或码域资源内进行信息发送或接收的天线端口。所述资源标识包括信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)资源标识,或SRS资源标识,或同步信号/同步信号块的资源标识,或PRACH上传输的前导序列的资源标识、或DMRS的资源标识,用于指示资源上的波束。例如对于下行信号的端口和下行信号的端口之间,或上行信号的端口和上行信号的端口之间的空间QCL关系,可以是两个信号具有相同的AOA或AOD,用于表示具有相同的接收波束或发送波束。又例如对于下行信号和上行信号间或上行信号与下行信号的端口间的QCL关系,可以是两个信号的AOA和AOD具有对应关系,或两个信号的AOD和AOA具有对应关系,即可以利用波束对应性,根据下行接收波束确定上行发送波束,或根据上行发送波束确定下行接收波束。
具有空间QCL关系的端口上传输的信号还可以理解为具有对应的波束,对应的波束包括以下至少之一:相同的接收波束、相同的发送波束、与接收波束对应的发送波束(对 应于有互易的场景)、与发送波束对应的接收波束(对应于有互易的场景)。
具有空间QCL关系的端口上传输的信号还可以理解为使用相同的空间滤波器(spatial filter)接收或发送信号。空间滤波器可以包括至少之一项以下处理过程:预编码,天线端口的权值,天线端口的相位偏转,天线端口的幅度增益。
具有空间QCL关系的端口上传输的信号还可以理解为具有对应的波束对连接(BPL,beam pair link),对应的BPL包括以下至少之一:相同的下行BPL,相同的上行BPL,与下行BPL对应的上行BPL,与上行BPL对应的下行BPL。
其次,波束互易性可以指终端具有建立用于传输上行信道的发送波束与下行信道的接收波束之间对应关系的能力,也就是说,在波束互易性的场景下,终端需要确定上行信道的发送波束时,终端可以基于波束的互易性,根据下行信道的接收波束确定传输上行信道的发送波束。
然而,在无波束互易性的场景下,终端无法基于波束的互易性,根据接收下行信道的接收波束确定上行信道的发送波束。为了解决在无波束互易性的场景下,终端无法确定发送上行信道的发送波束,本申请实施例提供了一种通信方法。
下面结合图2详细描述本申请实施例的通信方法。图2是本申请实施例的通信方法的示意性流程图。图2所示的方法包括:

应理解,上述实施例中网络设备向终端发送的配置信息可以承载于各种信令中,例如,MAC CE信令,RRC信令,DCI,系统消息,或广播消息。也可以是上述各种信令的组合,例如,网络设备可以通过RRC信令为终端配置一个配置信息候选集合,在通过DCI从上述配置信息的集合指示目标配置信息;或网络设备可以通过RRC信令为终端配置一个配置信息候选集合,再通过MAC CE指示终端从上述配置信息候选集合中,当前可以使用的配置信息子集,最后通过DCI指示终端在配置信息子集中使用的目标配置信息。
需要说明的是,网络设备发送的信息包括指示信息和配置信息,指示信息可以包括第一下行指示信息或第二下行指示信息,配置信息包括上述其他需要网络设备配置的配置信息,不同的信息可以有不同的承载方式,本申请实施例对此不作具体限定。可选的,指示信息承载于除DCI以外的信令中时,指示信息还可以携带自身的生效时间和/或失效时间。
例如,第一时间单元为时隙,第二时间单元为时隙,时隙n终端收到配置信息,指示4个时隙后生效,8个时隙后失效,或指示4个时隙后生效,生效后4个时隙失效,则通过配置信息确定的生效时间为在n+4时隙至n+8。
需要说明的是,前文描述的多种方案,可以单独或者结合使用。
