Description

一种信息传输方法及设备 技术领域
本发明实施例涉及通信领域,尤其涉及一种信息传输方法及设备。
背景技术
在长期演进(Long Term Evolution,LTE)系统中,用户设备(User Equipment,UE)可以通过向基站发送的探测参考信号(Sounding Reference Signals,SRS),以便基站根据接收到的SRS进行上行信道质量估计等操作。
另外,随着移动互联网的不断发展,低频的频谱资源已经愈发的紧张,为了满足日益增长的通信速率与容量的需求,第三代合作伙伴计划(The 3rd Generation Partnership Project,3GPP)将频率资源丰富的高频纳入了下一代无线通信系统采用的频谱范围内。但是,与采用低频作为工作频率的无线通信系统相比,采用高频作为工作频率的无线通信系统的传输损耗较大,也就是说,在相同的发射功率下,采用高频作为工作频率的无线通信系统的覆盖范围远低于采用低频作为工作频率的无线通信系统。因此,为了提高采用高频作为工作频率的无线通信系统的覆盖范围,业界引入了波束赋形技术,
综上,在采用高频作为工作频率的无线通信系统中,若UE需要发送SRS,则需要对SRS进行波束赋形处理。但是,由于LTE系统是以低频作为工作频率的,因此在LTE系统中UE发送SRS时,是无需进行波束赋形处理的,也就是说,现有技术并没有对SRS进行波束赋形的方案。

具体实施方式
为了实现对SRS的波束赋形,本发明实施例提供一种信息传输方法,其基本原理是:基站为UE配置包括至少一个第一资源,该第一资源用于UE发送目标信道和/或信号,并通过向UE发送用于指示第一资源与波束的对应关系或用于指示第一资源与第二资源的对应关系的第一指示信息,以便于UE可以根据第一资源和第一指示信息确定发送目标信道和/或信号所需的波束。这样,当目标信道和/或信号为SRS时,UE可以采用确定出的发送目标信道和/或信号所需的波束发送SRS,以实现对SRS的波束赋形。
波束可以用以下至少之一来标识:端口,预编码矩阵,空间特性参数;波束也可以是空间滤波器(spatial filtering)。

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。

图4为本发明实施例提供的一种信息传输方法的流程图,如图4所示,该方法可以 包括:
401、基站为UE配置至少一个第一资源。
其中,第一资源用于UE发送目标信道和/或信号。为了实现对目标信道和/或信号(例如,SRS)的波束赋形,基站可以为UE配置至少一个用于发送目标信道和/或信号的第一资源(例如,时域资源、频域资源、码域资源、天线端口中的一种或多种)。
其中,至少一个第一资源组成了资源组,并且,该资源组可以包括至少一个资源子组。
可选的,同一个资源子组中所有第一资源可以采用相同的频域资源或相同的码域资源。

进一步可选的,基站还可以向UE指示配置的资源组的分组方式,即向UE指示将配置的资源组划分为至少一个资源子组的分组方式。
402、UE获取基站为UE配置的至少一个第一资源。

其中,波束为上行发送波束或下行接收波束或下行发送波束或上行接收波束。在基站为UE配置的资源组的基础上,基站可以向UE发送用于指示资源组中包括的第一资源与波束的对应的关系的第一指示信息。
404、UE接收基站发送第一指示信息。

其中,在UE接收到基站发送的第一指示信息之后,UE可以根据第一指示信息中包含的对应关系,以及配置的资源组中包括的第一资源,确定出发送目标信道和/或信号所需的波束,即上行发送波束。
例如,当对应关系中的波束为上行发送波束时,UE可以直接将与第一资源对应的波束确定为上行发送波束;当对应关系中的波束为下行接收波束时,UE可以先获取到与第一资源对应的下行接收波束,然后根据下行接收波束,利用上下行波束的对应关系确定出上行发送波束;当波束为下行发送波束时,UE可以先根据第一资源和第一资源与波束的对应关系确定出下行发送波束,然后根据下行发送波束,利用上下行波束的对应关系 确定下行接收波束,最后根据下行接收波束,并利用上下行波束的对应关系确定出上行发送波束。
406、UE在第一资源和上行发送波束上发送目标信道和/或信号。
其中,在UE确定出上行发送波束之后,便可以在第一资源以及确定出的上行发送波束上发送目标信道和/或信号,以实现对目标信道和/或信号的波束赋形。

501、基站为UE配置至少一个第一资源。
其中,第一资源用于UE发送目标信道和/或信号。或者,第一资源用于UE接收目标信道和/或信号。
为了实现对目标信道和/或信号(例如,SRS)的波束赋形,基站可以为UE配置至少一个用于发送目标信道和/或信号的第一资源(例如,时域资源、频域资源、码域资源、天线端口中的一种或多种)。
其中,至少一个第一资源组成了资源组,并且,该资源组可以包括至少一个资源子组。
可选的,同一个资源子组中所有第一资源可以采用相同的频域资源或相同的码域资源。
可选的,基站还可以为UE配置资源组的具体使用方式。例如,使用方式可以为:周期性的采用配置的资源组传输目标信道和/或信号;或者,非周期性的采用配置的资源组传输目标信道和/或信号,在接收到基站发送的DCI后,采用配置的资源组传输目标信道和/或信号;或者,半持续(semi-persistent)的采用配置的资源组传输目标信道和/或信号,即在接收到基站发送的DCI或MAC CE之后,周期性的采用配置的资源组传输目标信道和/或信号,并在接收到基站发送的新的DCI或MAC CE之后停止发送。

502、UE获取基站为UE配置的至少一个第一资源。
基站可以通过信令通知UE上述第一资源。
503、基站向UE发送第一指示信息,第一指示信息用于指示第一资源与第二资源的对应关系。
其中,在UE向基站发送目标信道和/或信号之前,UE采用第二资源和相应的波束向基站发送了其他信息;或者在UE向基站发送目标信道和/或信号之前,基站采用第二资源和相应的波束向UE发送了其他信息,也就是说,已知第二资源和波束的对应关系,在此基础上,基站可以通过向UE发送用于指示第一资源与第二资源的对应关系的第一 指示信息,以便UE根据第一指示信息确定在第一资源上发送目标信道和/或信号所需的波束,或确定在第一资源上基站接收目标信道和/或信号所用的波束。
其中,为了能够使得UE可以在发送目标信道和/或信号时实现波束赋形,基站通过第一指示信息向UE指示为UE配置的资源组中第一资源与第二资源的对应关系。该第二资源包括UE在发送目标信道和/或信号之前向基站发送信息所采用的时域资源、频域资源、码域资源、天线端口中的至少一种;或者,第二资源包括UE在发送目标信道和/或信号之前基站向UE发送信息所采用的时域资源、频域资源、码域资源、天线端口中的至少一种。可选的,本发明实施例中涉及到的第二资源可以为用于以下信道和/或信号至少之一传输的资源:SRS、PRACH、PUSCH、PUCCH、上行跟踪信号、上行发现信号、上行波束参考信号、上行移动参考信号、上行解调参考信号、主同步信号、辅同步信号、同步信号块、物理广播信道的解调参考信号、CSI-RS、跟踪参考信号(Tracking reference signal,TRS)、相位跟踪参考信号(phase tracking reference signal,PT-RS)、物理下行控制信道的解调参考信号、物理下行共享信道的解调参考信号。可选的,所述物理下行控制信道可以为控制资源集合(CORESET,control resource set),也可以是承载随机接入响应或系统消息的控制信息的物理下行控制信道。可选的,所述物理下行共享信道可以是承载系统消息的物理下行共享信道。
也就是说,基站可以通过向UE发送已知与波束对应关系的第二资源与第一资源的对应关系,以便UE确定出所需的波束。
在具体实现中,基站可以通过以下不同的方式向UE指示为UE配置的资源组中每个第一资源与第二资源的对应关系。可选的,在以下实施方式中,所述第一资源与第二资源的对应关系包括以下至少之一:目标信道和/或信号的天线端口与所述第二资源上传输的信道和/或信号的天线端口具有准共址QCL关系;目标信道和/或信号采用的发送波束与所述第二资源上传输的信道和/或信号的发送波束相同;目标信道和/或信号采用的发送波束与所述第二资源上传输的信道和/或信号的接收波束对应;目标信道和/或信号采用的空间滤波器与所述第二资源上传输的信道和/或信号的空间滤波器相同
可选的,第二资源的标识和第二资源的关系可以是预定义或基站配置的。例如第二资源用于传输SRS时,第二资源的标识可以是SRI(SRS资源指示,SRS resource indicator)或基站配置或预定义第二资源标识与SRI或SRS资源的对应关系,可以使第二资源的标识对应一部分SRS资源或SRI,降低第二资源指示的开销。又例如第二资源为CSI-RS时,第二资源的标识可以是CRI(CSI-RS资源指示,CSI-RS resource indicator),也可以是基站配置或预定义的第二资源标识与CRI或CSI-RS资源或用户设备上报的CRI的对应关系。例如第二资源标识可以为低开销指示(LOI,low overhead indicator),可以使第二资源的标识对应一部分CSI-RS资源或CRI,降低第二资源指示的开销。
方式一:第一指示信息包括资源子组中每个第一资源与第二资源的对应关系。
其中,可以采用以下方式指示资源子组中每个第一资源与第二资源的对应关系:第一指示信息具体包括资源子组中每个第一资源的标识,以及与每个第一资源的标识对应的第二资源的标识;或者,第一指示信息具体包括用于指示每个第一资源上传输的目标信道和/或信号的天线端口与第二资源上传输的信号的天线端口具有QCL关系的信息;或 者,第一指示信息具体包括:每个第一资源对应的第二资源的标识。
可选的,当第一指示信息包含每个第一资源对应的第二资源的标识时,可以包含一个或多个第二资源的标识。可选的,第二资源的标识的数量与第一资源的数量相同;可选的,第一指示信息所指示的第二资源中每个第二资源与第一资源的对应关系可以是预定义的,例如第一指示信息所指示的第二资源中每个第二资源与第一资源依次对应。
并且,进一步的,在方式一的基础上,第一指示信息还包括每个第一资源与波束的可选范围的对应关系。
方式二:第一指示信息包括每个资源子组与第二资源的对应关系。
可以采用以下方式指示每个资源子组与第二资源的对应关系:第一指示信息具体包括每个资源子组的标识,以及与每个资源子组的标识对应的第二资源的标识;或者,第一指示信息具体包括用于指示每个资源子组的信号的天线端口与第二资源的信号的天线端口具有QCL关系的信息;或者,第一指示信息具体可以包括:每个资源子组对应的第二资源的标识。
其中,基站通过第一指示信息指示同一个资源子组的所有第一资源对应相同的第二资源,也就是说,对于同一个资源子组的所有第一资源,UE均采用同一个发送波束发送目标信道和/或信号,此时,相应的,可以通过预先定义或预先配置的方式,使得对于同一个资源子组的第一资源,基站采用不同的接收波束接收目标信道和/或信号。
方式三:第一指示信息包括每个资源子组与第二资源组的对应关系,第二资源组包括一个或多个第二资源。可以采用以下方式指示资源子组与第二资源组的对应关系:第一指示信息具体包括资源子组的标识,以及与资源子组的标识对应的第二资源组中第二资源的标识;或者,第一指示信息具体包括资源子组的标识,以及与资源子组的标识对应的第二资源组的标识。
方式四:第一指示信息包括与资源子组对应的第二资源组中第二资源的标识;
方式五:第一指示信息包括与资源组对应的第二资源组的标识。
可选的,在方式三至五中,第二资源组中的第二资源数量与资源组中的资源子组的数量相同。
可选的,在方式三至五中,第二资源组中的第二资源与资源组中的资源子组的对应关系可以是预定义的,例如依次对应。
可选的,例如第二资源为SRS资源,又例如第二资源为CSI-RS资源,又例如第一资源为SRS资源中的一个端口,第一资源子组为包含一个或多个SRS端口的SRS资源,第一资源组包含一个或多个SRS资源的SRS资源组。
可选的,第一指示信息的传输方法可以包括,基站可以通过高层信令,如RRC信令或MAC CE信令配置多个候选第二资源组,基站再通过MAC CE或DCI信令指示其中的一个候选第二资源组为所述第二资源组。
进一步可选的,一个或多个候选第二资源组组成一个候选第二资源组的集合,基站通过高层信令,如RRC信令或MAC CE信令,配置一个或多个候选第二资源组的集合, 基站再通过信令,如RRC信令或MAC CE信令指示其中的一个候选第二资源组的集合,基站再通过MAC CE或DCI信令指示所指示的候选第二资源组的集合中的一个候选第二资源组为所述第二资源组。
进一步可选的,同一个候选第二资源组的集合中包含的第二资源组中第二资源的数量相同,不同候选第二资源组的集合中包含的第二资源组中第二资源的数量可以不同。
进一步可选的,UE可以根据第一资源组中的第一资源子组的数量,确定一个候选第二资源组的集合。例如所确定的候选第二资源组的集合中第二资源组中的第二资源的数量等于所述第一资源组中的第一资源子组的数量。在表1中给出了一个可行的实施例,UE根据第一资源组中第一资源子组的数量,确定表中列,即确定候选第二资源组的集合,例如资源组中包含1个第一资源子组,则选择候选第二资源组的集合0,其中候选第二资源组的集合0中每个第二资源组中包含1个第二资源,由于此时第二资源组中仅一个第二资源,所以波束指示可以直接指示第二资源的标识;又例如,例如资源组中包含2个第一资源子组,则选择候选第二资源组的集合1,其中候选第二资源组的集合1中每个第二资源组中包含2个第二资源;又例如,例如资源组中包含4个第一资源子组,则选择候选第二资源组的集合2,其中候选第二资源组的集合2中每个第二资源组中包含4个第二资源,用这种预定义的对应关系可以保证第一资源子组有对应的第二资源。此外,基站通过MAC CE或DCI指示表中的波束指示项,从而确定表中的行,例如MAC CE或DCI中对应的域的比特为”00”,则选择资源组0.需要注意的是,下述表格中行与列仅为示例,可以互换,行和/或列的数量也可以增加或减少,也可以是其他表格中的一部分。下表中的域中的值为二进制的数,也可以用十进制、八进制或十六进制的数来表示。表中MAC CE或DCI中用于指示第一资源和第二资源对应关系的域与第二资源组的标识的对应关系,或MAC CE或DCI中用于指示第一资源和第二资源对应关系的域与第二资源的标识的对应关系可以通过列表(list),公式,一串字符,数组,或者为一段代码等形式体现。表中第一列中第一资源子组的个数也可以为其他数值,这里仅作为示例。

进一步的,以第二资源为SRS资源或CSI-RS资源为例,第一资源子组为SRS资源为例,表格1可以变为以下表格2。其中SRS/CSI-RS资源的标识可以为SRI或CRI,也可以基站配置或预定义SRI或CRI与SRS/CSI-RS资源的标识的对应关系。
下表中的域中的值为二进制的数,也可以用十进制、八进制或十六进制的数来表示。表中MAC CE或DCI中用于指示SRS资源和SRS/CSI-RS资源对应关系的域与SRS/CSI-RS资源组的标识的对应关系,或MAC CE或DCI中用于指示SRS资源和SRS/CSI-RS资源对应关系的域与SRS/CSI-RS资源的标识的对应关系可以通过列表(list),公式,一串字符,数组,或者为一段代码等形式体现。表中第一列中SRS资源的个数也可以为其他数值,这里仅作为示例。

并且,进一步的,在方式二至方式五的基础上,第一指示信息还包括:每个资源子组与波束的可选范围的对应关系。
方式六:第一指示信息包括每个第一资源与第二资源的对应关系。
可以采用以下方式指示每个第一资源与第二资源的对应关系:第一指示信息具体包括每个第一资源的标识,以及与每个第一资源的标识对应的第二资源的标识;或者,第一指示信息具体包括用于指示每个第一资源的信号的天线端口与第二资源的信号的天线端口具有QCL关系的信息;或者,第一指示信息包括与第一资源对应的第二资源的标识。
方式七:第一指示信息包括每个第一资源与第二资源组的对应关系,第二资源组包括至少一个第二资源。
可以采用以下方式指示每个第一资源与第二资源组的对应关系:第一指示信息具体包括每个第一资源的标识,以及与每个第一资源的标识对应的第二资源组中每个第二资源的标识;或者,第一指示信息具体包括每个第一资源的标识,以及与每个第一资源的标识对应的第二资源组的标识;或者,第一指示信息具体包括用于指示每个第一资源的信号的天线端口与第二资源组的信号的天线端口具有QCL关系的信息;或者,第一指示信息具体包括与第一资源对应的第二资源组的标识。
方式八:第一指示信息包括每个第一资源与波束的可选范围的对应关系。
可选的,在上述实施方式一至八中,所述第一指示信息可以承载于相同的信令,也可以承载于不同的信令,例如当第一指示信息承载于不同的信令时,所述第一资源的标识或第一资源子组的标识可以承载于信令1,上述实施方式中第一指示信息中第一资源的标识和第一资源子组的标识以外的信息可以承载于信令2.又例如,当第一信令承载于DCI中,DCI中可以不包含第一资源或第一资源子组或第一资源组的标识;当第一信令承载于MAC CE中时,第一MAC CE中可以包含第一资源或第一资源子组或第一资源组的标识,以及对应的第二资源的标识或第二资源组的标识。可选的,在上述实施方式一至八中,第一指示信息还可用于指示所述用户设备自行选择目标信道和/或信号的发送波束,或与目标信道和/或信号具有QCL关系的信号。
可选的,在上述实施方式一至八中,第一指示信息还可用于指示目标信道和/或信号采用之前使用的第k个发送波束或第一资源对应之前第k次指示的第二资源,k可以为基站配置或预定义的,如k=1或k=2.例如,在方式五中的表1中的MAC CE或DCI中用于指示第一资源和第二资源对应关系的域还可以用于指示所述目标信道和/或信号采用之前使用的第k个发送波束或所述第二资源为之前第k次指示的第二资源,或方式五中的表2中的MAC CE或DCI中用于指示SRS资源和SRS/CSI-RS资源对应关系的域还可以用于指示所述目标信道和/或信号采用之前使用的第k个发送波束,或所述SRS/CSI-RS 资源为之前第k次指示的SRS/CSI-RS资源
可选的,在上述实施方式一至八中,第一指示信息还可用于指示目标信道和/或信号采用的发送波束由UE自行确定或不限定与目标信道和/或信号所使用的天线端口有QCL关系的天线端口。例如,在方式五中的表1中的MAC CE或DCI中用于指示第一资源和第二资源对应关系的域还可以用于指示目标信道和/或信号采用的发送波束由UE自行确定或不限定与目标信道和/或信号所使用的天线端口有QCL关系的天线端口,或方式五中的表2中的MAC CE或DCI中用于指示SRS资源和SRS/CSI-RS资源对应关系的域还可以用于指示目标信道和/或信号采用的发送波束由UE自行确定或或不限定与所述SRS所使用的天线端口有QCL关系的天线端口。
可选的,在上述实施方式一至八中,基站可以发送第三指示信息,用于指示是否有第一指示信息,或第一指示信息中是否包含第二资源的标识,或第二资源组的标识,从而在不需要指示波束时降低信令开销。
可选的,在上述实施方式一至八中,所述第二资源与第三资源或第一资源的时域间隔为预定义的或基站配置的。所述第三资源为传输所述第一指示信息的部分或全部资源。
例如第一指示信息承载于RRC信令或MAC CE信令,或第一指示信息中的第二资源的标识,或第二资源组的标识承载于RRC信令或MAC CE信令,则第三资源可以为该RRC信令或MAC CE信令所在的PDSCH所在的时隙或子帧或符号或迷你时隙,本实施例中以时隙为例。又例如第一指示信息承载于DCI,或第一指示信息中的第二资源的标识,或第二资源组的标识承载于DCI,则第三资源可以为该DCI所在的PDCCH所在的时隙或子帧或符号或迷你时隙,本实施例中以时隙为例。
可选的,若第二资源承载非周期的信号,如非周期的SRS或非周期的CSI-RS,则预定义的该第二资源为发送该非周期信号的资源,第二资源与第三资源或第一资源的时域间隔为该非周期的信号所在的时隙与第三资源或第一资源的时隙的间隔。
可选的,若第二资源承载周期信号或半持续的信号,如周期性或半持续的SRS或CSI-RS,则在所述信号周期性发送的过程中可能基站会通过信令配置不同的波束,因此需要定义第二资源为所对应的周期性发送的信号的某次发送所占用的资源。
具体的,第一指示信息用于指示第二资源上传输的第二信号的资源指示,例如第二信号为SRS或CSI-RS,第二信号的资源指示为SRI或CRI或他们的标识。上述第二资源可以包含于第二资源组,指示方法可以为上述方式一至八中的指示方法。第二资源与第三资源或第一资源的时域间隔为预定义的或基站配置的有以下实施方法:
实施方法1:第二资源可以为第三资源a1个时隙前的倒数第a2次传输的第二信号的资源。例如,所述第三资源为时隙n或所在的时隙为时隙n,则第二资源为n-a1时隙之前倒数第a2次传输的第二信号的资源,如图5-1所示。a1可以为基站配置或预定义的,例如a1=0或a1=1.a2也可以为基站配置或预定义的,例如a2=1.其中a1可以为正值、负值或0,其中a1=0也可以理解为不定义a1,即第二资源可以为第三资源前的倒数第a2次传输的第二信号的资源;
实施方法2:第二资源可以为第三资源a1个时隙前的倒数第a2个不同波束或非QCL的第二信号的资源。例如,所述第三资源为时隙n或所在的时隙为时隙n,则第二资源为n-a1时隙之前倒数第a2个不同波束或非QCL的第二信号的资源,如图5-2所示。不同 波束还可以理解为不同的空间滤波器,或具有非QCL关系。a1可以为基站配置或预定义的,例如a1=0或a1=1.a2也可以为基站配置或预定义的,例如a2=1.其中a1可以为正值、负值或0,其中a1=0也可以理解为不定义a1,即第二资源可以为第三资源前的倒数第a2个不同波束的第二信号的资源.实施方法2相对实施方法1,实施方法1中多个a2值可能对应同一个波束,因此可以降低a2指示的开销;
实施方法3:第二资源可以为第一资源a1个时隙前的倒数第a2次传输的第二信号的资源。例如,所述第一资源所在的时隙为时隙n,则第二资源为n-a1时隙之前倒数第a2次传输的第二信号的资源,如图5-3所示。a1可以为基站配置或预定义的,例如a1=0或a1=1.a2也可以为基站配置或预定义的,例如a2=1.其中a1可以为正值、负值或0,其中a1=0也可以理解为不定义a1,即第二资源可以为第一资源前的倒数第a2次传输的第二信号的资源;
实施方法4:第二资源可以为第一资源a1个时隙前的倒数第a2个不同波束的第二信号的资源。例如,所述第一资源所在的时隙为时隙n,则第二资源为n-a1时隙之前倒数第a2个不同波束或非QCL的第二信号的资源,如图5-4所示。不同波束还可以理解为不同的空间滤波器,或具有非QCL关系。a1可以为基站配置或预定义的,例如a1=0或a1=1.a2也可以为基站配置或预定义的,例如a2=1.其中a1可以为正值、负值或0,其中a1=0也可以理解为不定义a1,即第二资源可以为第一资源前的倒数第a2个不同波束的第二信号的资源。实施方法4相对实施方法3,实施方法3中多个a2值可能对应同一个波束,因此可以降低a2指示的开销。
可选的,在上述实施方式一至八中,所述第一资源与第三资源或第二资源的时域间隔为预定义的或基站配置的。所述第三资源为传输所述第一指示信息的部分或全部资源。例如第一指示信息承载于RRC信令或MAC CE信令,或第一指示信息中的第二资源的标识,或第二资源组的标识承载于RRC信令或MAC CE信令,则第三资源可以为该RRC信令或MAC CE信令所在的PDSCH所在的时隙或子帧或符号或迷你时隙,本实施例中以时隙为例。又例如第一指示信息承载于DCI,或第一指示信息中的第二资源的标识,或第二资源组的标识承载于DCI,则第三资源可以为该DCI所在的PDCCH所在的时隙或子帧或符号或迷你时隙,本实施例中以时隙为例。
可选的,若第一资源承载非周期的目标信道和/或信号,如非周期的SRS或非周期的CSI-RS,则预定义的该第一资源为发送该非周期目标信道和/或信号的资源,第一资源与第三资源或第二资源的时域间隔为该非周期的目标信道和/或信号所在的时隙与第三资源或第二资源的时隙的间隔。
可选的,若第一资源承载周期信号或半持续的目标信道和/或信号,如周期性或半持续的SRS或CSI-RS,则考虑到第一指示信息存在一定的生效时延或模糊时间,因此需要规定第一指示信息具体生效的时间。
具体的,第一指示信息用于指示与第一资源对应的第二资源或第一资源与第二资源的对应关系,例如目标信道和/或信号为SRS。上述第一资源可以包含于第一资源组或第一资源子组,指示方法可以为上述方式一至八中的指示方法。第一资源与第三资源或第二资源的时域间隔为预定义的或基站配置的有以下实施方法:
实施方法1:第一资源可以为第三资源b1个时隙后的第b2次传输的目标信道和/或 信号的资源,或第一指示信息在第三资源b1个时隙后的第b2次传输的目标信道和/或信号开始生效。例如,所述第三资源为时隙n或所在的时隙为时隙n,则第一资源为n+b1时隙之后第b2次传输的目标信道和/或信号的资源,或第一指示信息在n+b1时隙之后第b2次传输的目标信道和/或信号时生效,如图5-5所示。b1可以为基站配置或预定义的,例如b1=0或b1=1。b2也可以为基站配置或预定义的,例如b2=1.其中b1=0也可以理解为不定义b1,即第一资源可以为第三资源后的第b2次传输的目标信道和/或信号的资源,或第一指示信息在第三资源后的第b2次传输的目标信道和/或信号开始生效;
实施方法2:第一资源可以为第二资源b1个时隙后的第b2次传输的目标信道和/或信号的资源,或第一指示信息在第二资源a1个时隙后的第b2次传输的目标信道和/或信号开始生效。例如,所述第二资源为时隙n或所在的时隙为时隙n,则第一资源为n+b1时隙之后第b2次传输的目标信道和/或信号的资源,或第一指示信息在n+b1时隙之后第b2次传输的目标信道和/或信号时生效,如图5-6所示。b1可以为基站配置或预定义的,例如b1=0或b1=1。b2也可以为基站配置或预定义的,例如b2=1.其中b1=0也可以理解为不定义b1,即第一资源可以为第二资源后的第b2次传输的目标信道和/或信号的资源,或第一指示信息在第二资源后的第b2次传输的目标信道和/或信号开始生效。
作为本实施例的另一种实现方法,所述第一指示信息中的用于指示第二资源或第二资源组的信息可以承载于第一DCI。所述第一DCI可以用于触发多于一个频域资源部分上传输目标信道和/或信号,所述频域资源部分可以为载波或带宽部分(BWP,bandwidth part)。BWP可以是基站为UE配置的一段带宽,具有唯一的子载波间隔和CP类型,可以用于数据传输。本实施例中以目标信道和/或信号为SRS为例。此时第一资源或第一资源子组或第一资源组包含多个频域资源部分,可以理解为每个第一资源位于一个频域资源部分,或每个第一资源子组位于一个频域资源部分,或第一资源位于多个频域资源部分。所述频域资源部分中的一些频域资源部分为不进行PUSCH的传输或不进行PUSCH和PUCCH的传输的频域资源部分。此时所述第一指示信息用于指示多个频域资源部分上的波束或对应的第二资源或第二资源组。
具体的,第一DCI中包含一个或多个部分,例如,第一DCI可包括block 1,block 2,…,block C,C为正整数。第一DCI中C个部分中的一个或多个部分可以用于承载第一指示信息中的用于指示第二资源或第二资源组的信息。可选的,若C个部分为第一DCI中的部分比特,则第一DCI中的其他一个或多个部分可以用于承载其他UE的第一指示信息,此时将第一DCI用于指示不同用户设备的SRS传输。此时第一DCI中的C个部分中的一个部分用于指示b1个第二资源以及b2个传输功率控制(TPC,Transmission Power Control)参数,b1>1,b2>1。例如第一DCI中的C个部分中的一个部分包含b1个第二资源的标识,或包含b1个第二资源的一个或多个第二资源组的标识。具体第一DCI中的C个部分中的一个部分(例如可以是第一DCI中的一个block)的比特数以及具体含义有以下方式:
方式一:b2根据b1、载波数以及每个载波内的BWP数目确定,例如b2=b1*载波数*每个载波内的BWP的数目。此时b1个第二资源与b2个TPC的对应关系可以是高层信令如RRC信令或MAC CE信令配置的,或预定义的,例如按照TPC的排序分为b1组, 每组对应1个第二资源,如按顺序对应。从而实现每个资源每个波束都有确定的TPC,进行闭环功率控制调整。此时C=1.
针对这种方式,每个部分(block)对应于一个用户设备,针对该用户设备包含以下比特:
(1)┌log2(b1)┐个bit,其中,┌.┐表示向上取整,基站通过第一DCI的一个部分(block)中的所述┌log2(b1)┐个bit指示该用户设备在所述部分对应的载波内的BWP上使用的第二资源标或第二资源的一个或多个第二资源组的标识;
(2)┌log2(b2)┐个bit,其中,┌.┐表示向上取整,基站通过第一DCI的一个部分(block)中的所述┌log2(b2)┐个bit指示所述用户设备的功控命令,所述功控命令可以是TPC。其中,b1个第二资源与b2个TPC的对应关系可以是高层信令如RRC信令或MAC CE信令配置的,或预定义的。
方式二:b2根据b1确定,例如b2=b1。此时b1个第二资源与b2个TPC的对应关系可以是高层信令如RRC信令或MAC CE信令配置的,或预定义的,例如按照TPC的排序和所指示的第二资源的排序一一对应。从而实现每个波束都有确定的TPC,进行闭环功率控制调整。进一步地,此时C>1,所述第一DCI中的C个部分中每个部分对应一个载波上的BP,例如C可以根据载波数和每个载波内的BWP的数目确定,例如C=载波数*每个载波内的BWP的数目.
针对这种方式,每个部分(block)对应于一个载波上的一个BWP,针对该载波上的一个BWP包含以下比特:
(1)┌log2(b1)┐个bit,其中,┌.┐表示向上取整,基站通过第一DCI的一个部分(block)中的所述┌log2(b1)┐个bit指示载波上的一个BWP内用户设备使用的第二资源标或第二资源的一个或多个第二资源组的标识;
(2)┌log2(b2)┐个bit,其中,┌.┐表示向上取整,基站通过第一DCI的一个部分(block)中的所述┌log2(b2)┐个bit指示一个载波上的一个BWP内用户设备的功控命令,所述功控命令可以是TPC。其中,b1个第二资源与b2个TPC的对应关系可以是高层信令如RRC信令或MAC CE信令配置的,或预定义的。
此时,一个用户设备可以对应于一个或多个部分(block)。也就是说,基站可以通过第一DCI内的一个或多个部分(block)指示一个用户设备使用的第二资源标或第二资源的一个或多个第二资源组的标识。
方式三:b2根据b1和载波数确定,或根据b1和BWP数目确定,例如b2=b1*载波数,或b2=b1*BWP的数目。此时b1个第二资源与b2个TPC的对应关系可以是高层信令如RRC信令或MAC CE信令配置的,或预定义的,例如按照TPC的排序分为b1组,每组对应1个第二资源,如按顺序对应。从而实现每个资源每个波束都有确定的TPC,进行闭环功率控制调整。此时C=1.
针对这种方式,每个部分(block)对应于一个用户设备,针对该用户设备包含以下比特:
(1)┌log2(b1)┐个bit,其中,┌.┐表示向上取整,基站通过第一DCI的一个部分(block)中的所述┌log2(b1)┐个bit指示该用户设备在所述部分(block)对应的载波 内或BWP上使用的第二资源标或第二资源的一个或多个第二资源组的标识;
(2)┌log2(b2)┐个bit,其中,┌.┐表示向上取整,基站通过第一DCI的一个部分(block)中的所述┌log2(b2)┐个bit指示所述用户设备的功控命令,所述功控命令可以是TPC。其中,b1个第二资源与b2个TPC的对应关系可以是高层信令如RRC信令或MAC CE信令配置的,或预定义的。
方式四:b2根据b1确定,例如b2=b1。此时b1个第二资源与b2个TPC的对应关系可以是高层信令如RRC信令或MAC CE信令配置的,或预定义的,例如按照TPC的排序和所指示的第二资源的排序一一对应。从而实现每个波束都有确定的TPC,进行闭环功率控制调整。进一步地,此时C>1,所述第一DCI中的C个部分中每个部分对应一个载波上的BP,例如C可以根据载波数或BWP的数目确定,例如C=载波数,或C=BWP的数目.
针对这种方式,每个部分(block)对应于一个载波上或一个BWP,针对该载波或一个BWP包含以下比特:
(1)┌log2(b1)┐个bit,其中,┌.┐表示向上取整,基站通过第一DCI的一个部分(block)中的所述┌log2(b1)┐个bit指示该载波或者BWP内用户设备使用的第二资源标或第二资源的一个或多个第二资源组的标识;
(2)┌log2(b2)┐个bit,其中,┌.┐表示向上取整,基站通过第一DCI的一个部分(block)中的所述┌log2(b2)┐个bit指示所述载波或者BWP用户设备的功控命令,所述功控命令可以是TPC。其中,b1个第二资源与b2个TPC的对应关系可以是高层信令如RRC信令或MAC CE信令配置的,或预定义的。
此时,一个用户设备可以对应于一个或多个部分(block)。也就是说,基站可以通过第一DCI内的一个或多个部分(block)指示一个用户设备使用的第二资源标或第二资源的一个或多个第二资源组的标识。
可选的,用户设备根据b1、载波数以及每个载波中的BWP数目确定采用实施方法一或实施方法二。例如,当b1*载波数*每个载波内的BWP的数目大于或大于等于L时,采用实施方法一,否则采用实施方法二。其中L为预设或协议规定的或基站配置的,例如基站可通过RRC信令配置L的值。

作为本发明的一种扩展,上述信息传输方法还可以扩展到下行,此时目标信道和/或信号为基站向UE发送的,第一资源为下行传输的资源,此时目标信道和/或信号可以为以下至少之一:主同步信号、辅同步信号、同步信号块、物理广播信道、CSI-RS、跟踪参考信号(Tracking reference signal,TRS)、相位跟踪参考信号(phase tracking reference signal,PT-RS)、解调参考信号(DMRS,Demodulation reference signal)、物理下行控制信道、物理下行共享信道、控制资源集合CORESET。
上述第一指示信息的配置方法用于指示下行传输的目标信道和/或信号时,基站向UE发送第一指示信息,第一指示信息用于指示第一资源与第二资源的对应关系。
其中,在基站向UE发送目标信道和/或信号之前,UE采用第二资源和相应的波束向基站发送了其他信息;或者在基站向UE发送目标信道和/或信号之前,基站采用第二资源和相应的波束向UE发送了其他信息,UE采用相应的接收波束接收了第二资源上传输的信号,也就是说,UE已知第二资源和接收波束的对应关系,在此基础上,基站可以通过向UE发送用于指示第一资源与第二资源的对应关系的第一指示信息,以便UE根据第一指示信息确定在第一资源上UE接收目标信道和/或信号所需的波束,或确定在第一资源上基站发送目标信道和/或信号所用的波束。例如UE根据第一指示信息确定在第一资源上UE接收目标信道和/或信号所需的波束为UE接收第二资源上传输的信号的接收波束,或所述UE感觉第一指示信息确定,目标信道和/或信号传输所使用的天线端口与所述第二资源上传输的信号所使用的天线端口具有QCL关系。具体第一指示信息的传输方法可以为上述任一方式或它们的组合。

其中,在UE接收到基站发送的第一指示信息之后,UE可以根据第一指示信息中包含的对应关系,以及配置的资源组中包括的第一资源,先确定出与第一资源对应的第二资源,然后根据已知的第二资源和波束的对应关系,根据第二资源对应的波束确定目标信道和/或信号的上行发送波束或上行接收波束。
例如,当是UE在第二资源和对应的波束上发送了其他信息时,则已知的是第二资源和上行发送波束的对应关系,此时,可以直接将与第二资源对应的波束确定为目标信道和/或信号的上行发送波束,或直接将与第二资源对应的接收波束确定为目标信道和/或信号的上行接收波束,当是基站在第二资源和对应的波束上发送了其他信息时,则已知的是第二资源和下行接收波束的对应关系,此时,可以根据与第二资源对应的波束,利用上下行波束的对应关系确定出目标信道和/或信号的上行发送波束。可选的,上述波束还可以是空间滤波器,或第二资源上传输的信号的天线端口与目标信道和/或信号的天线端口具有QCL关系。

可选的,若UE判断所述第三信号和/或信道与所述目标信道和/或信号的发送波束或接收波束相同,或UE需要判断所述第三信号和/或信道的天线端口与所述目标信道和/或信号的天线端口具有QCL关系,则UE发送目标信道和/或信号,以及第三信号和/或信道。若UE判断所述第三信号和/或信道与所述目标信道和/或信号的发送波束不相同或接收波束不相同,或UE判断所述第三信号和/或信道的天线端口与所述目标信道和/或信号的天线端口不具有QCL关系,则有以下实施方法:
实施方法一:UE根据预定义的优先级,确定在所述符号上传输目标信道和/或信号与第三信号和/或信道之一。例如所述预定义的优先级可以为PUSCH的优先级低于SRS,PUCCH的优先级高于SRS。此时例如目标信道和/或信号为SRS,第三信号和/或信道为PUSCH,则PUSCH在SRS的符号上不映射,并进行速率匹配。又比如目标信道和/或信号为PUCCH,第三信号和/或信道为SRS,则SRS在PUCCH的符号上不映射。此外,例如还可以定义PUSCH中承载上行控制信息或承载DMRS的符号优先级高于SRS,或PUSCH中前置的DMRS(front-loaded DMRS)的符号优先级高于SRS,PUSCH中额外的DMRS(additional DMRS)的优先级低于或高于SRS。又例如,可以定义承载CSI的PUCCH的优先级低于SRS,例如目标信道和/或信号为PUCCH,第三信号和/或信道为SRS,则PUCCH不映射在SRS的符号上。可选的,可以通过预定义的方式调整PUCCH的符号数、格式、占用频域资源的数量或占用的RB数,使PUCCH不映射在SRS的符号上,且UE可以发送PUCCH。

其中,在UE接收到基站发送的第一指示信息之后,UE可以根据第一指示信息中包含的对应关系,以及配置的资源组中包括的第一资源,先确定出与第一资源对应的第二资源,然后根据已知的第二资源和波束的对应关系,根据第二资源对应的波束确定目标信道和/或信号的下行接收波束。

本发明实施例提供的信息传输方法,基站为UE配置用于传输目标信道和/或信号的至少一个第一资源,并通过向UE发送用于指示第一资源与第二资源的对应关系的第一指示信息,以便于UE可以根据第一资源和第一指示信息确定发送目标信道和/或信号所需的波束。这样,当目标信道和/或信号为SRS时,UE可以采用确定出的发送目标信道和/或信号所需的波束发送SRS,以实现对SRS的波束赋形。
图6为本发明实施例提供的另一种信息传输方法的流程图,如图6所示,该方法可以包括:
601、UE向基站发送能力指示信息。
其中,为了使得基站能够根据UE的波束能力为UE配置资源,UE可以将自身的波束能力上报至基站,具体的,UE可以通过向基站发送能力指示信息,来上报自身的波束能力。
示例性的,UE可以通过消息3(Message 3)和/或上行高层信令将能力指示信息发送至基站。
能力指示信息中包括UE在能力类型中支持的最大波束数,或者,能力指示信息中包括UE在能力类型中支持的最大波束数的量化值。能力类型可以包括波束管理阶段和/或波束的可选范围,另外,能力类型可以是预定义的也可以是基站配置的。
示例性的,当能力类型包括波束管理阶段时,该波束管理阶段可以包括:U-1阶段、U-2阶段和U-3阶段。其中,在U-1阶段,基站可以对UE的不同发送波束进行测量,以支持UE发送波束或基站接收波束的波束选择,在U-2阶段,基站可以对自身不同的接收波束进行测量(此时UE相应的可以在同一个发送波束上向基站发送信号),以支持可能的基站内或基站间的接收波束切换,在U-3阶段,基站可以对自身相同的接收波束进行测量(此时UE相应的可以在不同的发送波束上向基站发送信号),以使得在波束赋形的场景下UE可以改变自身的发送波束。
当能力类型包括波束的可选范围时,该波束(指的是发送波束)的可选范围可以包 括:0度-360度,45度-135度等等。
例如,当能力类型包括波束管理阶段,且采用UE在能力类型中支持的最大波束数上报能力指示信息时,如图7所示,假设UE在U-1阶段支持的最大波束数为4,UE在U-3阶段支持的最大波束数为5,则UE向基站发送的能力指示信息可以包括:在U-1阶段支持的最大波束数为4,在U-3阶段支持的最大波束数为5。
再例如,当能力类型包括波束的可选范围,且采用UE在能力类型中支持的最大波束数的量化值上报能力指示信息时,假设UE在0度-360度支持的最大波束数为16,UE在45度-135度支持的最大波束数为4,且波束数大于等于8且小于16时,对应的量化值为2,波束数为大于等于1且小于8时,对应的量化值为1,则UE向基站发送的能力指示信息可以包括:在0度-360度支持的最大波束数的量化值为2,在45度-135度支持的最大波束数的量化值为1。
602、基站接收UE发送的能力指示信息。
603、基站根据能力指示信息为UE配置资源组。
其中,资源组可以包括至少一个资源子组,资源子组包括至少一个第一资源,第一资源用于UE发送目标信道和/或信号。
在本发明实施例中,第一资源可以包括以下至少一种:时域资源、频域资源、码域资源、天线端口。目标信道和/或信号包括以下至少一种:SRS、PRACH、PUSCH、PUCCH、上行跟踪信号、上行发现信号、上行波束参考信号、上行移动参考信号、上行解调参考信号。
在基站接收到UE发送的能力指示信息之后,基站可以根据UE在不同能力类型中支持的最大波束数或支持的最大波束数的量化值,为UE配置在相应能力类型对应的资源组。其中,原则是:为UE配置的资源组可以划分为的资源子组的数量小于或等于UE在相应的能力类型中的最大波束数。
需要说明的是,步骤603具体描述与本发明另一实施例中步骤401的具体描述类似,对于本发明实施例中步骤603的具体描述,可以参考本发明另一实施例中步骤401的具体描述,本发明实施例在此不再详细赘述。
604、基站向UE发送第二指示信息。
其中,为了实现对资源组的划分,基站还可以向UE发送用于UE将资源组划分为至少一个资源子组的第二指示信息。
605、UE获取基站为UE配置的资源组。
606、UE接收基站发送的第二指示信息。
607、UE根据第二指示信息将资源组划分为至少一个资源子组。
其中,在UE获取到基站配置的资源组,并接收到基站发送的第二指示信息之后,UE可以根据第二指示信息指示的分组方式,将获取到的资源组划分为至少一个资源子组。
608、基站向UE发送第一指示信息,第一指示信息用于指示第一资源与波束的对应关系。
其中,波束可以为上行发送波束,也可以为下行接收波束。为了能够使得UE可以在发送目标信道和/或信号时实现波束赋形,基站通过第一指示信息向UE指示为UE配 置的资源组中每个第一资源与波束的对应关系。
在具体实现中,基站可以通过以下不同的方式向UE指示为UE配置的资源组中每个第一资源与波束的对应关系。
方式一:第一指示信息包括资源子组中每个第一资源的标识,以及与每个第一资源的标识对应的波束的编号。
