Description

用于无线通信的电子设备和方法、计算机可读存储介质
本申请要求于2019年1月3日提交中国专利局、申请号为201910004300.X、发明名称为“用于无线通信的电子设备和方法、计算机可读存储介质”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
本申请涉及无线通信技术领域，具体地涉及无线通信系统中的上行波束管理。更具体地，涉及一种用于无线通信的电子设备和方法以及计算机可读存储介质。
背景技术
随着无线通信技术的发展，通信终端比如用户设备(User Equipment，UE)可以具有多个天线面板，每个天线面板可以形成不同空间方向的波束。在一个时间单位内，每一个天线面板仅可以在一个方向上发射波束，但是多个天线面板可以同时发射波束。为此，基站侧可以为UE配置多个探测参考信号(Sounding Reference Signal，SRS)资源集合，以用于上行波束管理的目的。
图1示出了具有4个天线面板的UE的示意图，其中，分别为4个天线面板分配上行波束扫描所需要的SRS资源集合，每一个SRS资源集合中包括N个SRS资源。图2示出了使用图1中所分配的SRS资源集合执行上行波束扫描的示意图，可以看出，在同一个OFDM符号上，4个天线面板分别在4个方向上发射波束。

具体实施方式
在下文中将结合附图对本公开的示范性实施例进行描述。为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。

<第一实施例>
图3示出了根据本申请的一个实施例的用于无线通信的电子设备100的功能模块框图，如图3所示，电子设备100包括：获取单元101，被配置为从基站获取基站为用户设备(UE)配置的用于波束管理的SRS资源集合的信息；以及确定单元102，被配置为根据预定规则确定该信息指示的SRS资源集合所对应的UE的天线面板，其中，预定规则限定用于波束管理的SRS资源集合与UE的天线面板之间的映射关系。
其中，获取单元101和确定单元103可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片、处理器。并且，应该理解，图3中所示的电子设备中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。这同样适用于随后要描述的其他电子设备的示例。
电子设备100例如可以设置在用户设备(UE)侧或者可通信地连接到UE。这里，还应指出，电子设备100可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备100可以工作为用户设备本身，并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储用户设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，基站、其他用户设备等等)间的通信，这里不具体限制收发器的实现形式。这同样适用于随后关于用户设备侧的电子设备的其他配置示例的描述。
在Rel.15的标准中，SRS资源集合与UE的天线面板的关联关系、即哪个天线面板使用哪个SRS资源集合，是UE自己实现的，这种关联信息对于基站而言是未知的。在本实施例中，通过使用预定规则来确定SRS资源集合与UE的天线面板之间的对应关系，可以使得基站也能够获知SRS资源集合与UE的天线面板之间的关联关系，以实现更精确的上行波束管理。
例如，获取单元101可以通过无线资源控制(Radio Resource Control，RRC)信令来获取上述信息。其中，UE可以通过UE能力上报来上报其波束能力，例如所配置的天线面板的信息。基站通过RRC信令为天线面板配置用于波束管理的SRS资源集合。
为了便于理解，图4示出了通过RRC配置来执行SRS发送的示意图，其中，发送周期为20个时隙，偏置为10个时隙。因此，UE使用被配置的SRS资源集合，从接收到RRC配置的时隙之后的10个时隙处开始执行SRS发送。此外，UE还可以在接收到来自基站的用于激活的MAC CE之后，使用被配置的SRS资源执行SRS发送，并且在接收到来自基站的用于去激活的MAC CE之后停止SRS发送，如图5所示，其中，发送周期也是20个时隙。
应该理解，为了节省资源，基站可以为UE配置少于其天线面板个数的数量的SRS资源集合，即，只使用一部分天线面板来发送SRS。为了使得基站能够确定所接收的SRS信号是由UE的哪个天线面板所发送的，本实施例设置了预定规则作为基站的参考。
在一个示例中，预定规则可以包括：具有较小的标识符(ID)的SRS资源集合映射至具有较小的标识符的天线面板。例如，UE具有4个天线 面板(面板0至3)，基站为该UE配置的SRS资源集合分别为SRS资源集合10、SRS资源集合18、SRS资源集合21和SRS资源集合29。根据预定规则，将按照如下方式进行关联(或映射)：SRS资源集合10对应于面板0，SRS资源集合18对应于面板1，SRS资源集合21对应于面板2，SRS资源集合29对应于面板3。
在基站所分配的SRS资源集合的数量少于4的情况下，比如仅分配了2个SRS资源集合，则可以如下进行关联(或映射)：SRS资源集合10对应于面板0，SRS资源集合18对应于面板1，面板2和面板3对应的资源集合为空。
在这种情况下，基站基于该预定规则，可以准确地判断所接收到的SRS信号来自于UE的哪个天线面板。应该理解，以上只是给出了预定规则的一个示例，该示例并不是限制性的，还可以采取其他适当的预定规则。
此外，UE的天线面板的开关状态可以随时间而改变，例如，基站可以通过各种方式来控制UE的各个天线面板的开关。作为一个示例，确定单元102还可以被配置为基于上述SRS资源集合的信息来改变各个天线面板的开关状态。天线面板的开关状态可以是周期性地、半静态地或者非周期地改变的。相应地，SRS资源集合的配置也可以是周期性的、半静态的或者非周期的。
例如，获取单元101可以被配置为周期性地获取所述信息，从而确定单元102根据该信息周期性地改变各个天线面板的开关状态，例如打开或关闭UE的特定天线面板。在前述UE具有四个天线面板的示例中，在所配置的SRS资源集合由4个(10、18、21和29)变为2个(10和18)的情况下，天线面板2和3被关闭。
另外，获取单元101还可以被配置为从基站获取MAC CE来激活或去激活与所述信息指示的SRS资源集合对应的天线面板，该方式被称为半静态方式，可参考图5所示。MAC CE中可包含关于SRS资源集合的ID的信息，UE改变与该ID对应的天线面板的开关状态，比如在当前为开的情况下将该天线面板改变为关，以及在当前为关的情况下将该天线面板改变为开。图6示出了用于激活或去激活天线面板的MAC CE的一个示例，其中包含SRS资源集合的ID以及SRS资源集合所属的部分频 带(Bandwidth Part，BWP)的ID。
或者，确定单元102还可以基于下行控制信息(Downlink Control Information，DCI)来改变与所述信息指示的SRS资源集合对应的天线面板的开关状态，该方式被称为非周期的方式。例如，在UE有4个天线面板的情况下，可以使用DCI中的2比特信息来改变其中一个天线面板的开关状态。
另一方面，也可以由UE自身来控制其天线面板的开关状态。在这种情况下，电子设备100还可以包括发送单元103，用于向基站通知其天线面板的开关状态的改变，如图7所示。例如，发送单元103被配置为在特定天线面板被打开的情况下，向基站发送对于用于波束管理的SRS资源集合的配置请求，以及在特定天线面板被关闭的情况下，向基站发送释放与该特定天线面板对应的SRS资源集合的请求。
其中，这些请求中可以包括与特定天线面板具有映射关系的SRS资源集合的标识符。该标识符例如可以基于存储的SRS资源集合与天线面板的历史对应关系而获得。这些请求可以通过RRC信令发送给基站。
此外，发送单元103还可以被配置为在特定天线面板被打开的情况下，向基站发送激活用于波束管理的SRS资源集合的请求，以及在特定天线面板被关闭的情况下，向基站发送去激活与该特定天线面板对应的SRS资源集合的请求。这些请求可以通过MAC信令来发送。类似地，这些请求中也可以包括与特定天线面板具有映射关系的SRS资源集合的标识符。
根据本申请的该方面，通过使用SRS资源集合的标识符作为指示来通知基站进行SRS资源配置，能够使得基站获知UE针对特定天线面板的开关操作。
综上所述，根据本实施例的电子设备100通过使用预定规则来限定SRS资源集合与UE的天线面板之间的映射关系，使得基站能够以确定的方式获知UE的各个天线面板具体使用了哪个SRS资源集合，实现更加准确和有效的波束管理。
<第二实施例>
图8示出了根据本申请的另一个实施例的电子设备200的功能模块框图，如图8所示，电子设备200包括：生成单元201，被配置为生成为UE配置的用于波束管理的SRS资源集合的信息，其中，该信息指示的SRS资源集合与UE的天线面板之间具有由预定规则限定的映射关系；以及发送单元202，将该信息发送给UE。
其中，生成单元201和发送单元202可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片、处理器。并且，应该理解，图8中所示的电子设备中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。这同样适用于随后要描述的其他电子设备的示例。
电子设备200例如可以设置在基站侧或者可通信地连接到基站。本申请中所述的基站也可以是收发点(Transmit Receive Point，TRP)或者接入点(Access Point,AP)。这里，还应指出，电子设备200可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备200可以工作为基站本身，并且还可以包括诸如存储器、收发器(未示出)等外部设备。存储器可以用于存储基站实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，用户设备、其他基站等等)间的通信，这里不具体限制收发器的实现形式。这同样适用于随后关于基站侧的电子设备其他配置示例的描述。
由于SRS资源集合与UE的天线面板之间具有由预定规则限定的映射关系，因此基站能够根据该预定规则确定每一个SRS资源集合将会与UE的哪个天线面板相关联，从而实现特定于天线面板的波束管理。
预定规则例如包括：具有较小的标识符的SRS资源集合映射至具有较小的标识符的天线面板。具体示例已在第一实施例中给出，在此不再重复。并且，可以理解，预定规则并不限于此，而是可以适当地修改或改变。
在一个示例中，发送单元202可以通过RRC信令来发送所述信息。
如第一实施例中所述，该信息可以用于改变各个天线面板的开关状态。根据时域属性的不同，这种改变可以是周期性的、半静态的或者非周期的。
例如，发送单元202可以周期性地发送所述信息，以实现天线面板 的开关状态的周期性改变。或者，除了RRC信令之外，发送单元202还可以通过MAC CE来指示UE激活或去激活与所述信息指示的SRS资源集合对应的天线面板，以实现对天线面板的开关状态的半静态控制。MAC CE中还可以包括要改变其对应的天线面板的开关状态的SRS资源集合的ID，例如图6所示。
此外，发送单元202还可以通过DCI来指示UE改变与所述信息指示的SRS资源集合对应的天线面板的开关状态。这是一种非周期的控制方式。例如，在UE具有4个天线面板的情况下，可以通过DCI中的2比特信息来指示要改变哪个天线面板的开关状态。
综上所述，根据本申请的电子设备200能够基于基站和UE所共知的预定规则，以确定的方式获知UE的各个天线面板具体使用了哪个SRS资源集合，从而实现更加准确和有效的波束管理。
<第三实施例>
在上下行信道具有波束对称性的情况下比如在时分双工(Time division Duplexing，TDD)系统中，基站也可以通过下行参考信号来进行上行波束管理。如图9所示，基站使用信道状态信息参考信号(Channel state Information Reference Signal，CSI-RS)作为波束扫描的参考信号，UE使用天线面板的两个接收(Rx)波束进行接收，并上报该CSI-RS资源的ID、即CRI。基站接收到上报后，可以获知适当的发射波束。如果基站能够同时获得UE使用哪个天线面板来进行了接收的相关信息，则可以相应地配置用于波束管理的SRS资源集合。
图10示出了根据本实施例的用于无线通信的电子设备300的功能模块框图，如图10所示，该电子设备300包括：确定单元301，被配置为基于预定规则确定与UE的特定天线面板对应的用于波束管理的SRS资源集合，其中，预定规则限定用于波束管理的SRS资源集合与UE的天线面板之间的映射关系；以及发送单元302，被配置为将所确定的SRS资源集合的信息发送给基站。
其中，确定单元301和发送单元302可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片、处理器。电子设备300例如可以设置在用户设备(UE)侧或者可通信地连接到UE。
预定规则例如可以包括：具有较小的标识符的SRS资源集合映射至具有较小的标识符的天线面板。根据该预定规则，确定单元301可以确定与特定天线面板对应的SRS资源集合，并且基站侧也可以根据该预定规则而获知同样的对应关系，从而在接收到该SRS资源集合的信息之后，基站可以确定UE的特定天线面板具体是哪一个。这里，SRS资源集合的信息可以为SRS资源集合的标识符(ID)。当存在多个特定天线面板时，信息中将包含多个SRS资源集合的ID。
在一个示例中，确定单元301可以根据历史配置的SRS资源集合来进行所述确定。历史配置中例如包括基站为UE最近配置的SRS资源集合的ID。
确定单元301还可以被配置为基于下行参考信号的测量结果来确定特定天线面板，并且发送单元302将所确定的特定天线面板对应的SRS资源集合的标识符包括在下行参考信号测量报告中发送给基站。下行参考信号例如为前述CSI-RS信号或同步信号块(Synchronization Signal Block，SSB)。
图11示出了在下行参考信号为CSI-RS的情况下，UE所发送的下行参考信号测量报告的示例的图。其中，前四行为上报的四个发射波束对应的CSI-RS资源的ID、即CRI；第5行至第8行分别为第1行至第4行的CSI-RS资源的参考信号接收功率(Reference Signal Receiving Power，RSRP)；第9行至第12行分别为对第1行至第4行的发射波束接收效果最好的接收波束所在的天线面板所对应的SRS资源集合的标识符。可以看出，对于一个发射波束，可以存在多个最优接收波束且这些波束分别属于不同的天线面板，在这种情况下，要将多个天线面板各自对应的SRS资源集合的ID包括在测量报告中，如图11的第9行和第12行所示。
图11仅示出了下行参考信号测量报告的一个示例，并不是限制性的，报告的形式和内容均可以适当地改变。基站在收到该测量报告后，例如基于后四行的内容通过使用预定规则可以确定对应的天线面板，并基于所确定的天线面板来为UE配置SRS资源集合。
相应地，本实施例还提供了一种基站侧的电子设备400，如图12所示，该电子设备400包括：获取单元401，被配置为从UE获取用于波束 管理的SRS资源集合的信息；以及确定单元402，被配置为基于预定规则确定与所述信息指示的SRS资源集合对应的UE的天线面板，其中，预定规则限定用于波束管理的SRS资源集合与UE的天线面板之间的映射关系。
其中，获取单元401和确定单元402可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片、处理器。
类似地，例如，预定规则可以包括：具有较小的标识符的SRS资源集合映射至具有较小的标识符的天线面板。
上述信息例如包括在UE上报的下行参考信号测量报告中，并且该信息为SRS资源集合的标识符。下行参考信号例如为CSI-RS或者SSB。确定单元402例如可以根据为UE历史配置的SRS资源集合，使用预定规则来确定对应的天线面板。
此外，确定单元402还可以被配置为基于所确定的天线面板来为UE配置SRS资源集合。
综上所述，根据本实施例的电子设备300和400能够基于预定规则来通过SRS资源集合的信息来实现UE与基站之间的关于特定天线面板的信息的传递，进一步实现基于下行参考信号的上行波束管理。
<第四实施例>
在上文的实施方式中描述用于无线通信的电子设备的过程中，显然还公开了一些处理或方法。下文中，在不重复上文中已经讨论的一些细节的情况下给出这些方法的概要，但是应当注意，虽然这些方法在描述用于无线通信的电子设备的过程中公开，但是这些方法不一定采用所描述的那些部件或不一定由那些部件执行。例如，用于无线通信的电子设备的实施方式可以部分地或完全地使用硬件和/或固件来实现，而下面讨论的用于无线通信的方法可以完全由计算机可执行的程序来实现，尽管这些方法也可以采用用于无线通信的电子设备的硬件和/或固件。
图13示出了根据本申请的一个实施例的用于无线通信的方法的流程图，该方法包括：从基站获取基站为UE配置的用于波束管理的SRS资源集合的信息(S11)；以及根据预定规则确定该信息指示的SRS资源 集合所对应的UE的天线面板(S12)，其中，预定规则限定用于波束管理的SRS资源集合与UE的天线面板之间的映射关系。该方法可以在UE侧执行。

在UE侧控制天线面板的开关状态的示例中，在特定天线面板被打开的情况下，向基站发送对于用于波束管理的SRS资源集合的配置请求；以及在特定天线面板被关闭的情况下，向基站发送释放与该特定天线面板对应的SRS资源集合的请求。这些请求可以通过RRC信令发送。
或者，在特定天线面板被打开的情况下，向基站发送激活用于波束管理的SRS资源集合的请求；以及在特定天线面板被关闭的情况下，向基站发送去激活与该特定天线面板对应的SRS资源集合的请求。这些请求可以通过MAC信令发送。
上述请求中可以包括与特定天线面板具有映射关系的SRS资源集合的标识符。
图14示出了根据本申请的另一个实施例的用于无线通信的方法的流程图，该方法包括：生成为UE配置的用于波束管理的SRS资源集合的信息(S21)，其中，该信息指示的SRS资源集合与UE的天线面板之间具有由预定规则限定的映射关系；以及将该信息发送给UE(S22)。该方法可以在基站侧执行。
其中，预定规则可以包括：具有较小的标识符的SRS资源集合映射至具有较小的标识符的天线面板。在步骤S22中可以通过RRC信令来发 送所述信息。在一个示例中，这种发送可以是周期性的。
上述方法还可以包括如下步骤：通过MAC CE来指示UE激活或去激活与所述信息指示的SRS资源集合对应的天线面板；或者通过DCI来指示UE改变与所述信息指示的SRS资源集合对应的天线面板的开关状态。
图15示出了根据本申请的另一个实施例的用于无线通信的方法的流程图，该方法包括：基于预定规则确定与UE的特定天线面板对应的用于波束管理的SRS资源集合(S31)，其中，预定规则限定用于波束管理的SRS资源集合与UE的天线面板之间的映射关系；以及将所确定的SRS资源集合的信息发送给基站(S32)。该方法可以在UE侧执行。
在一个示例中，可以基于下行参考信号的测量结果来确定特定天线面板，并在步骤S32中将所确定的特定天线面板对应的SRS资源集合的标识符包括在下行参考信号测量报告中发送给基站。下行参考信号例如为CSI-RS或SSB。在步骤S31中可以根据历史配置的SRS资源集合来进行所述确定。

[关于基站的应用示例]
(第一应用示例)
图17是示出可以应用本公开内容的技术的eNB或gNB的示意性配置的第一示例的框图。注意，以下的描述以eNB作为示例，但是同样可以应用于gNB。eNB 800包括一个或多个天线810以及基站设备820。基站设备820和每个天线810可以经由RF线缆彼此连接。
天线810中的每一个均包括单个或多个天线元件(诸如包括在多输入多输出(MIMO)天线中的多个天线元件)，并且用于基站设备820发送和接收无线信号。如图17所示，eNB 800可以包括多个天线810。例如，多个天线810可以与eNB 800使用的多个频带兼容。虽然图17示出其中eNB 800包括多个天线810的示例，但是eNB 800也可以包括单个天线810。
