本申请主张在2017年8月8日在中国提交的中国专利申请号No.201710672894.2的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及无线通信技术领域，特别涉及一种指示上行传输的方法及装置。
背景技术
相关技术中的第四代(4th-generation，4G)移动通信系统中，主要使用6GHz以下频段作为工作频段，频谱资源紧张现象日趋严重，极大地限制了对高数据速率业务的支持。4G以后的下一代通信系统研究中，将使用6GHz以上的频段作为工作频段。由于高频段具有较为丰富的空闲频率资源，因此可以为数据传输提供更大的吞吐量。第三代合作伙伴计划(3rd generation partnership project，3GPP)已经完成了高频信道建模工作，高频信号的波长短，同低频段相比，能够在同样大小的天线面板上布置更多的天线阵元，利用波束赋形技术形成指向性更强、波瓣更窄的波束。因此，将大规模天线和高频通信相结合，成为未来通信技术的趋势。
移动通信系统中，在使用6GHz以下的频段时，无需采用波束成型技术，网络设备(例如：基站)或用户设备(user equipment，UE)简单地以全向的方式进行传送。而使用6GHz以上的频段时，由于高频段信号的路径损耗较大，若仍以全向方式传输信号，则信号的覆盖范围非常小，因此，须采用波束成型技术，利用方向性波束来传输信号。通常在基站与用户设备初始接入流程之后基站与用户设备之间传输数据之前，进行上行波束训练和下行的波束训练以选择合适的波束进行后续的数据发送。
相关技术中，可以采用探测导频信号来进行上行波束训练，由于每个探测导频信号(Sounding Reference Signal，SRS)(也可称为信道探测参考信号) 资源(即发送SRS的时域资源和频域资源)对应一个UE的发送波束。因此在上行波束训练过程中用户设备每次只能采用一个发送波束在SRS资源上发送SRS信号，这样在完成上行波束训练的过程中时延较大，使得上行波束训练的效率较低。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行详细地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。
在本公开实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更好或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。本文中符号“/”表示关联对象是或者的关系，例如A/B表示A或者B。
本公开实施例中的术语“第一”和“第二”等是用于区别不同对象，而不是用于描述特定顺序。例如，第一配置信息和第二配置信息是用于区别不同配置信息，而不是用于描述不同配置信息的特定顺序。
在本公开的描述中，除非另有说明，“多个”的含义是指两个或两个以上。 例如，多个波束是指两个或两个以上的波束。
本申请提供的技术方案可以应用于各种通信系统，例如，5G通信系统，未来演进系统或者多种通信融合系统等等。可以包括多种应用场景，例如，机器对机器(machine to machine，M2M)、设备到设备(Device to Device，D2D)、宏微通信、增强型移动宽带(enhance mobile broadband，eMBB)、超高可靠性与超低时延通信(ultra reliable&low latency communication，uRLLC)以及海量机器类通信(massive machine type communication，mMTC)等场景。例如：本申请实施例可以应用于与5G通信系统中的网络设备与用户设备之间的通信。
相关技术中，在终端发送上行数据之前，可以采用探测导频信号来进行上行波束训练，在上行波束训练过程中UE每次只能采用一个波束在SRS资源上向网络设备发送SRS信号，这样在完成上行波束训练的过程中需要发送较多次SRS，使得上行波束训练的效率较低。
为了解决上述问题，本公开实施例提供一种指示上行传输的方法，该方法可以生成用于指示为UE配置的SRS资源中的多个部分与多个波束的映射关系的第一指示信息，并将该第一指示信息发送至UE，因此UE在为其分配的SRS资源上发送SRS时，可以根据该第一指示信息选择上述映射关系涉及的多个波束中的至少两个波束，在该SRS资源中与该至少两个波束对应的部分上发送SRS，从而可以实现同时采用至少两个波束传输SRS，减少上行波束训练过程的时延，提高上行波束训练的效率。
进一步的，本公开实施例提供的指示上行传输的方法中，由于可以向UE发送用于为UE配置数据传输资源的第四配置信息，并且可以生成用于指示允许UE同时传输数据的波束的第二指示信息，并向UE发送该第二指示信息，因此在基站需要UE做多流并行传输(即基站需要UE同时采用多个波束向其发送数据)、或者UE需要多流并行传输等情况下，UE可以在基站为其指示的允许同时传输数据的波束中选择至少两个波束在基站为其配置的数据传输资源上传输数据。从而可以在数据传输阶段实现多流并行传输。
需要说明的是，本公开实施例提供的指示上行传输的方法中，网络设备可以为该网络设备的覆盖范围内的多个终端分别配置SRS资源和波束，为了 更加清楚地描述本公开实施例的技术方案，本公开实施例中仅以网络设备为该网络设备的覆盖范围内的一个用户设备配置SRS资源和波束为例进行示例性的描述。
本公开实施例提供的指示上行传输的方法，可以应用于无线通信系统。示例性的，如图1所示的无线通信系统为本公开实施例提供的一种无线通信系统的系统架构示意图。在图1中，该无线通信系统包括用户设备和网络设备。在实际应用中上述用户设备与网络设备之间的连接可以为无线连接。
本公开实施例中的网络设备可以是全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)网络中的基站收发信台(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的NB(NodeB)，还可以是长期演进(Long Term Evolution，LTE)中的eNB或eNodeB(Evolved Node B)。网络设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器。网络设备还可以是5G通信系统中的网络设备或未来演进网络中的网络设备。
示例性的，在本公开实施例中，图1所示的网络设备可以为基站，下面结合图2对本公开实施例中的基站的各个构成部件进行详细的说明。如图2所示，基站可以包括：射频拉远单元(radio remote unit，RRU)、基带处理单元(building base band unit，BBU)和天线，RRU和BBU之间可以用光纤连接，RRU再通过同轴电缆及功分器(或者耦合器)连接至天线，通常，一个BBU可以连接多个RRU。

首先对本公开实施例中可能涉及到的一些概念进行介绍。
SRS：SRS是上行参考信号(也称为上行导频信号)的一种，其是由UE提供给基站用于信道估计的一种已知信号。
SRS资源：通常SRS资源是指SRS所采用的伪随机序列、发送SRS的频域资源、时域资源和码域资源等。本公开实施例中所涉及的SRS资源以发送SRS的频域资源和时域资源为例进行说明。
SRS资源块：本公开实施例中，SRS资源块是指SRS资源的最基本配置单元。即基站为UE配置SRS资源时，至少配置一个SRS资源块。
天线端口：本公开实施例中提到的天线端口是指天线支持的用于传输的逻辑端口，其与物理的天线端口并没有一一对应的关系，而是与参考信号具有一定的对应关系。可以采用某个或某些天线端口用于传输某一类的参考信号，例如，本公开实施例中可以采用多个天线端口传输SRS。
下面对本公开实施例提供的指示上行传输的方法和装置进行示例性的说明。
本公开实施例提供的指示上行传输的方法可以应用于上行波束训练过程和数据发送过程。
需要说明的是，下面在本公开实施例中均以网络设备为基站为例进行示例性的说明。
本公开实施例中，基站为UE配置的SRS资源包括三种不同的情况。其中，第一种情况为：基站为UE配置的SRS资源为多天线端口的SRS资源块；第二种情况为：基站为UE配置的SRS资源为SRS资源集合，该SRS资源集合由多个SRS资源块组成；第三种情况为：基站为UE配置的SRS资源为SRS资源集合，该SRS资源集合由多个SRS资源块组成，其中至少一个SRS资源块为多天线端口的SRS资源块。
由于在上述三种不同情况下本公开实施例提供的指示上行传输的方法的流程有所不同，因此为了更加清楚的说明本公开实施例提供的指示上行传输的方法，下面的实施例中将在上述三种情况下分别进行示例性的说明。
第一种情况：
如图5所示，本公开实施例提供的指示上行传输的方法包括以下步骤S101-S115。
S101、UE向基站发送波束信息；相应的，基站接收该波束信息。
S102、基站根据该波束信息确定UE可用于上行波束训练的波束。
其中，上述可用于上行波束训练的波束为UE的发送波束。
本公开实施例提供的指示上行传输的方法可以应用于多种网络场景。
可选的，该方法可以应用于对称性网络的场景，例如应用于采用时分双工(time division duplexing，TDD)技术的网络；该方法还可以应用于非对称性网络的场景，例如应用于采用频分双工(frequency division duplexing，FDD)技术的网络。
场景1、应用于对称性网络的场景。
基站和UE的接收波束均与发送波束一一对应，例如，UE包括10个发送波束，可以为发送波束1至发送波束10，则UE相应的也包括10个接收波束，可以为接收波束1和接收波束10。
在场景1中，在下行波束训练过程中执行上述S101和S102。示例性的，在下行波束训练过程中，UE接收基站的多个发送波束发送的SRS，在该多个波束中选择至少一个波束，并确定与该基站的发送波束对应的UE的发送波束，将该UE的发送波束的信息反馈给基站。例如，在UE采用UE的接收波束接收基站的发送波束时，UE确定某些接收波束(例如，接收波束1和接收波束2)接收到的SRS的信号质量较好时，UE则认为与接收波束1和接收波束2对应的发送波束1和发送波束2发送SRS时的信号质量也较好，UE可以将该发送波束1和发送波束2的信息(具体的可以为发送波束1的索引和发送波束2的索引)反馈给基站。从而基站可以知道UE的发送波束1和发送波束2发送信号时的信号质量较好，然后可以通过下述S103-S109的方法指示UE基于发送波束1和发送波束2进行上行波束训练。
场景2、应用于非对称性网络的场景。
首先，UE可以将其的发送波束的信息上报给基站，从而基站相应的执行上述S102。例如，基站可以接收UE上报的用于进行上行波束训练的发送波束的信息(例如波束的标识)，以使得基站可以获知用于进行上行波束训练的波束。然后通过下述S103-S109的方法指示UE基于基站指示的UE的发送波束进行上行波束训练。
可选的，波束的标识可以为探测导频信号资源索引(SRS Resource Index，SRI)SRI或信道状态信号导频信号资源索引(Channel status information Reference Signal Resource Index，CRI)。
通常，SRI可以用于指示UE的发送波束，CRI用于指示基站的发送波束，因此一般基站会采用SRI向UE指示UE的发送波束。本公开实施例中，由于在上述场景1中，当基站采用CRI指示基站的发送波束时，UE可以根据基站指示的发送波束确定对应的UE的发送波束，因此在上述场景1中，也可以采用CRI向UE指示UE的发送波束。
需要说明的是，本公开实施例中下面的内容所涉及到的波束均是指UE的发送波束。
S103、基站向UE发送第一配置信息；相应的，UE接收该第一配置信息。
S104、UE根据该第一配置信息，确定基站为其配置的SRS资源。
其中，该第一配置信息用于为UE配置多天线端口的SRS资源块。
可选的，本公开实施例中，基站可以根据接收到的UE发送的波束信息，确定UE可用于上行波束训练的波束，然后基站可以根据UE可用于上行波束训练的波束的个数为UE配置多天线端口的SRS资源块。例如，若基站确定UE可用于上行波束训练的发送波束的个数为2个，则基站可以为UE配置2天线端口的SRS资源块。
S105、基站生成第一指示信息。
S106、基站向UE发送该第一指示信息；相应的，UE接收该第一指示信息。
其中，该第一指示信息用于指示为UE配置的SRS资源中的多个部分与多个波束的映射关系；其中，不同的部分对应不同的波束，该映射关系中的多个波束允许同时用于传输。
需要说明的是，本公开实施例中，SRS资源可以划分为多个部分，基站可以配置多个部分中每个部分与波束的对应关系，也可以配置该多个部分中的一些部分与波束的对应关系。其中，每个部分可以对应一个波束。在本公开的下述实施例中，均是以基站在配置SRS资源中的多个部分与多个波束的映射关系时，为每一个部分均配置了对应的波束为例进行说明的。
在为UE配置的SRS资源为多天线端口的SRS资源块的情况下，为UE配置的SRS资源中的不同部分分别为不同天线端口的资源，因此上述第一指示信息具体可以用于指示SRS资源块对应的多个天线端口与多个波束的映射关系。
示例性的，以基站为UE配置2天线端口的SRS资源块为例，基站可以指示2个波束与2个天线端口的映射关系，假设该两个波束为波束1和波束2，该2个天线端口为天线端口1和天线端口2，则基站可以配置波束1对应天线端口1，波束2对应天线端口2。
可选的，上述映射关系中的波束可以用波束的标识指示，上述映射关系中的天线端口可以用端口标识来指示。
示例性的，可以采用CRI1指示上述示例中的波束1，采用CRI2指示上述示例中的波束2，采用port1指示上述天线端口1，采用port2指示上述天线端口2，则天线端口与波束的映射关系可以如表1所示。
表1
天线端口 波束
port1 CRI1
port2 CRI2
其中，上述为UE配置的资源为多天线端口的SRS资源块，可以理解为将为UE配置的SRS资源块可以映射到多个天线端口。
示例性的，以上述为UE配置的资源为一个2天线端口的SRS资源块为例，假设该两天端口为UE的天线端口1和天线端口2，则将上述SRS资源映射到该天线端口1和天线端口2的SRS资源导频图样可以如图6所示。
S107、UE根据该第一指示信息，在基站为其配置的SRS资源上发送SRS；相应的，基站接收SRS。
本公开实施例中，基站向UE发送该第一指示信息，相应的，UE接收该第一指示信息，然后UE可以在基站为其配置的SRS资源上发送SRS。
其中，上述UE在基站为其配置的SRS资源上发送SRS可以理解为：UE可以在第一指示消息中指示的映射关系中的多个波束中选择至少一个波束，并在该至少一个波束对应的天线端口的资源上发送SRS。
本公开实施例中，当UE在上述映射关系中的多个波束中选择至少两个波束，并在该至少两个波束对应的天线端口的资源上发送SRS时，可以在上行波束训练过程中实现UE用多个波束同时向基站发送SRS，从而可以提高上行波束训练的效率。
S108、基站根据UE发送的SRS，确定目标波束。
S109、基站向UE发送该目标波束的信息；相应的，UE接收目标波束的信息。
示例性的，若上述S108中UE采用了两个波束向基站发送SRS，则基站可以在该两个波束中确定目标波束，并将该目标波束的信息(可以为波束的标识)发送至基站。例如，UE可以在上述至少两个波束中选择发送的SRS的信号质量较好的波束作为目标波束。
其中，上述目标波束即为通过波束训练过程选择的用于传输数据的波束。
本公开实施例中通过上述S101-S109实现上行波束训练的过程之后，在UE发送上行数据时，可以采用该目标波束向UE发送数据。具体的，可以采用该目标波束在基站为UE配置的数据传输资源上发送数据。
可选的，在基站需要UE做多流并行传输(即基站需要UE同时采用多个波束向其发送数据)、或者UE需要多流并行传输等情况下，本公开实施例还包括下述步骤S110-S115，这一过程可以基于上述S103-S106实现，与其他其他步骤无依赖关系。
S110、基站向UE发送第二指示信息；相应的，UE接收该第二指示信息。
S111、UE根据该第二指示信息，确定允许其同时传输数据的波束。
其中，该第二指示信息用于指示允许UE同时传输数据的波束。具体的，第二指示信息具体用于指示上述SRS资源块对应的多个天线端口，以使得UE在接收到该第二指示信息时，可以采用上述映射关系(即基站指示的天线端口与波束的映射关系)确定与该多个天线端口对应的波束为允许同时传输数据的波束。
可选的，该第二指示信息中可以携带该SRS资源块的标识和该SRS资源块对应的多个天线端口的端口标识，以指示该SRS资源块对应的多个天线端口；该第二指示信息中还可以携带该SRS资源块的标识，以指示该SRS资源 块中所有的天线端口。
可选的，上述第二指示信息具体用于指示一个SRS资源块对应的多个天线端口。该第二指示信息中的SRS资源的标识的数量，可以通过网络配置或者预先约定的规则，限定在一个第二指示信息中携带的SRS资源块的标识的数量为一个。
S112、基站向UE发送第四配置信息；相应的，UE接收该第四配置信息。
S113、UE根据该第四配置信息，确定基站为其配置的数据传输资源。
其中，该第四配置信息用于为UE配置数据传输资源。
需要说明的是，本公开实施例不限定上述S110-S111与上述S112-S113的执行顺序，即本公开实施例中，可以先执行上述S110-S111，后执行上述S112-S113；也可以先执行上述S112-S113，后执行上述S110-S111；还可以同时执行上述S110-S111与上述S112-S113。
S114、UE从允许用于同时传输的波束中选择至少两个波束。
S115、UE采用该至少两个波束在基站为其配置的数据传输资源上向基站发送数据；相应的，基站接收数据。
上述S109-S115的过程中，本公开实施例中基站可以向UE发送用于为UE配置数据传输资源的第四配置信息，并且可以生成用于指示允许UE同时传输数据的波束的第二指示信息，并向UE发送该第二指示信息，因此在基站需要UE做多流并行传输(即基站需要UE同时采用多个波束向其发送数据)、或者UE需要多流并行传输等情况下，UE可以在基站为其指示的允许同时传输数据的波束中选择至少两个波束在基站为其配置的数据传输资源上传输数据。
可选的，本公开实施例中的部分方法步骤之间可以合并，例如上述S103和S105可以合并为一个方法步骤，即将上述第一配置信息和上述第一指示信息携带在同一个信息中发送给UE。
第二种情况：
如图7所示，本公开实施例提供的指示上行传输的方法可以包括以下步骤S201-S215。

本公开实施例中，基站向UE发送第二配置信息，相应的，UE接收该第二配置信息，并根据该第二配置信息确定基站为其配置的SRS资源为SRS资源集合，且该SRS资源集合由多个SRS资源块组成。
本公开实施例中，基站可以根据接收到的UE发送的波束信息，确定UE可用于上行波束训练的波束，然后基站可以根据UE可用于上行波束训练的波束的个数为UE配置由多个SRS资源块组成的SRS资源集合。例如，若基站确定UE可用于上行波束训练的波束的个数为2个，则基站可以为UE配置由2个SRS资源块组成的SRS资源集合。
S205、基站生成第一指示信息。
S206、基站向UE发送该第一指示信息；相应的，UE接收该第一指示信息。
其中，该第一指示信息用于指示为UE配置的SRS资源中的多个部分与多个波束的映射关系；其中，不同的部分对应不同的波束，该映射关系中的多个波束允许同时用于传输。
在为UE配置的SRS资源为由多个SRS资源块组成的SRS资源集合的情况下，为UE配置的SRS资源中的不同部分分别为不同SRS资源块，因此上述第一指示信息具体可以用于指示SRS资源集合中的多个SRS资源块与多个波束的映射关系。
示例性的，以基站为UE配置由2个SRS资源块组成的资源集合为例，基站可以指示该2个波束与2个SRS资源块的映射关系，假设该两个波束为波束1和波束2，该2个SRS资源块为SRS资源块1和SRS资源块2，则基站可以配置波束1对应SRS资源块1，波束2对应SRS资源块2。

本公开实施例中，基站向UE发送该第一指示信息，相应的，UE接收该第一指示信息，然后UE可以在基站为其配置的SRS资源上发送SRS。
其中，上述UE在基站为其配置的SRS资源上发送SRS可以理解为：在第一指示消息中指示的映射关系中的多个波束中选择至少一个波束，并在该至少一个波束对应的SRS资源块和/或天线端口的资源上发送SRS。
本公开实施例中，当UE在上述映射关系中的多个波束中选择至少两个波束，并在至少两个波束对应的SRS资源块和/或天线端口的资源上发送SRS时，可以在上行波束训练过程中实现UE用多个波束同时向基站发送SRS，从而可以提高上行波束训练的效率。
S308、基站根据UE发送的SRS，确定目标波束。
S309、基站向UE发送该目标波束的信息；相应的，UE接收目标波束的信息。
对于S308和S309的描述具体可以参见上述关于S108和S109的相关描述，此处不再赘述。
本公开实施例中通过上述S301-S309实现上行波束训练的过程之后，在UE发送上行数据时，可以采用该目标波束向UE发送数据。具体的，可以采用该目标波束在基站为UE配置的数据传输资源上发送数据。

S310、基站向UE发送第二指示信息；相应的，UE接收该第二指示信息。
S311、UE根据该第二指示信息，确定允许其同时传输数据的波束。
其中，该第二指示信息用于指示允许UE同时传输数据的波束。具体的， 第二指示信息具体用于指示SRS资源集合中的SRS资源块和/或SRS资源块对应的天线端口，以使得UE在接收到该第二指示信息时，可以采用上述映射关系(即基站指示的SRS资源集合中的SRS资源块和/或SRS资源块对应的天线端口与多个波束的映射关系)确定与该SRS资源集合中的SRS资源块和/或SRS资源块对应的天线端口对应的波束为允许同时传输数据的波束。
可选的，该第二指示信息中可以携带该SRS资源集合的标识、该SRS资源集合中的多个SRS资源块的标识、以及该多个SRS资源块对应的天线端口的标识，以指示SRS资源集合中的SRS资源块和/或SRS资源块对应的天线端口；该第二指示信息中还可以携带该SRS资源集合的标识，以指示SRS资源集合中的所有SRS资源块以及所有SRS资源块对应的所有天线端口。
示例性的，以基站为UE配置的SRS资源为3个SRS资源块组成的SRS资源集合，且该SRS资源集合中各个部分的映射关系如上述表3和表4所示为例。在基站指示波束CRI1、CRI2、CRI3和CRI4时，基站可以在该第二指示信息中携带S1、S2和S3；也可以在该第二指示信息中携带S1、S2、S3以及port1和port2；还可以通过在该第二指示信息中直接携带该SRS资源集合的标识。
又示例性的，在基站指示上述表3和表4中的波束CRI1、CRI2和CRI3时，基站可以在该第二指示信息中携带S1、S2、S3以及port1；基站还可以在该第二指示信息中携带S1、S2和port1。
可选的，上述第二指示信息具体用于指示一个SRS资源集合中的SRS资源块和/或SRS资源块对应的天线端口。该第二指示信息中的SRS资源集合的标识的数量，可以通过网络配置或者预先约定的规则，限定在一个第二指示信息中携带的SRS资源集合的标识的数量为一个。
S312、基站向UE发送第四配置信息；相应的，UE接收该第四配置信息。
S313、UE根据该第四配置信息，确定基站为其配置的数据传输资源。
其中，该第四配置信息用于为UE配置数据传输资源。
需要说明的是，本公开实施例不限定上述S310-S311与上述S312-S313的执行顺序，即本公开实施例中，可以先执行上述S310-S311，后执行上述S312-S313；也可以先执行上述S312-S313，后执行上述S310-S311；还可以 同时执行上述S310-S311与上述S312-S313。
S314、UE从允许用于同时传输的波束中选择至少两个波束。
S315、UE采用该至少两个波束在基站为其配置的数据传输资源上向基站发送数据；相应的，基站接收数据。
上述S310-S315的过程中，本公开实施例中基站可以向UE发送用于为UE配置数据传输资源的第四配置信息，并且可以生成用于指示允许UE同时传输数据的波束的第二指示信息，并向UE发送该第二指示信息，因此在基站需要UE做多流并行传输(即基站需要UE同时采用多个波束向其发送数据)、或者UE需要多流并行传输等情况下，UE可以在基站为其指示的允许同时传输数据的波束中选择至少两个波束在基站为其配置的数据传输资源上传输数据。
