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探测参考信号(Sounding Reference Signal，SRS)资源配置。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
在3GPP Rel.16的标准化过程中，非周期的SRS的波束发射方向是通过无线资源控制(Radio Resource Control，RRC)信令进行配置的。为了增加该信号的波束发射方向的配置灵活性，还可以通过MAC CE信令来针对单个非周期SRS资源更新其波束发射方向。
另外，基站可以为用户设备(User Equipment，UE)配置多个SRS资源集合，每个SRS资源集合可以包括多个SRS资源以及针对这些SRS资源的上行功率控制参数等。

根据本申请的实施例的电子设备和方法，通过针对波束发射方向被第一MAC CE信令更新的第一非周期SRS资源更新其PL RS，能够为该第一非周期SRS资源配置适当的PL RS，从而准确地确定SRS的上行发射功率。
通过以下结合附图对本公开的优选实施例的详细说明，本公开的这些以及其他优点将更加明显。

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。
在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本公开，在附图中仅仅示出了与根据本公开的方案密切相关的设备结构和/或处理步骤，而省略了与本公开关系不大的其他细节。
如前所述，可以通过MAC CE信令来更新某一个非周期SRS资源的波束发射方向。其中，波束发射方向信息是针对单个非周期SRS资源的，例如包括Spatioal Relation或者Spatioal Relation Info，其中包含一个下行参考信号的信息比如信道状态信息参考信号(Channel state Information Reference Signal，CSI-RS)或者同步信号块(Synchronization Signal Block，SSB)的标识符(ID)，或者一个上行参考信号的信息比如另一个SRS资源的ID。
另一方面，SRS资源的上行功率控制的参数比如pathlossReferenceRS、alpha、p0等是以一个SRS资源集合为单位来配置的。例如，pathlossReferenceRS指示一个周期性下行参考信号比如周期性CSI-RSS或SSB，UE通过测量该pathlossReferenceRS的接收功率、即参考信号接收功率(Reference Signal Receiving Power，RSRP)，同时UE已知该pathlossReferenceRS(以下简称“PL RS”)的发送功率，从而可以计算出该波束方向上的信道的上行和下行路径损耗。该路径损耗可用于调整SRS的上行发射功率。
因此，在通过MAC CE更新一个非周期SRS资源的波束发射方向的情况下，可能出现该非周期SRS资源所属的SRS资源集合的PL RS的方向与更新后的波束发射方向例如一致性较差，从而不再适合作为该非周期SRS资源的PL RS。如果此时仍然使用原来的PL RS，则可能无法正确地调整该非周期SRS资源的上行发射功率或者调整的准确度较差。为了便于理解，图1示出了通过MAC CE信令更新SRS资源集合中的一个非周期SRS资源的波束发射方向的示意性示例。其中，SRS资源集合A中包括M个SRS资源，SRS资源1的波束发射方向信息SRS-SpatialRelationInfo由MAC CE信令更新。此时，SRS资源集合A的PL RS可能不再适合于SRS资源1。本实施例提供了针对这种非周期SRS资源重新确定其PL RS的多种方法的示例。
<第一实施例>
图1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1所示，电子设备100包括：第一确定单元101，被配置为确定波束发射方向被第一MAC CE信令更新的第一非周期SRS资源；以及第二确定单元102，被配置为基于第一MAC CE信令中的第一非周期SRS资源的波束发射方向信息或者第二MAC CE信令，重新确定用于第一非周期SRS资源的PL RS。
其中，第一确定单元101和第二确定单元102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1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UE等等)间的通信，这里不具体限制收发器的实现形式。
此外，本文中的第一、第二等序数词仅是为了区分的用途，而不表示任何时间或空间上的顺序或者其他含义。
UE例如从基站接收到第一MAC CE信令，第一确定单元101确定第一MAC CE信令要更新第一非周期SRS资源的波束发射方向。第一MAC CE信令中包括作为更新目标的第一非周期SRS资源的波束发射方向信息，如前所述，该波束发射方向信息可以包括下行参考信号的信息或者上行参考信号的信息。
在本实施例中，第二确定单元102可以基于第一MAC CE信令中的波束发射方向信息来重新确定第一非周期SRS资源的PL RS，这种方式不需要额外的信令；或者，也可以基于基站发送的第二MAC CE信令来重新确定第一非周期SRS资源的PL RS。应该注意，这里虽然描述为第一MAC CE信令和第二MAC CE信令，但是并不是限制性的，第一MAC CE信令和第二MAC CE信令也可以为同一条MAC CE信令。
在一个示例中，第二确定单元102被配置为基于波束发射方向信息中包括的下行参考信号或上行参考信号的信息来重新确定所述PL RS。
例如，在波束发射方向信息中包括下行参考信号的信息比如下行参考信号的ID的情况下，第二确定单元102被配置为将该下行参考信号作为第一非周期SRS资源的PL RS，其中，下行参考信号例如为CSI-RS或者SSB。这样设置的PL RS与第一非周期SRS资源具有良好的方向一致性。另一方面，在波束发射方向信息中包括上行参考信号的信息比如另一个SRS的ID的情况下，第二确定单元102被配置为将该上行参考信号所在的SRS资源集合的PL RS作为第一非周期SRS资源的PL RS。该示例的示意图如图3所示，其中，第一MAC CE更新SRS资源1的波束发射方向。
此外，在波束发射方向信息中包括下行参考信号的信息比如下行参考信号的ID的情况下，第二确定单元102还可以被配置为将与下行参考信号具有QCL_TypeD关系的SSB作为第一非周期SRS资源的PL RS。另一方面，在波束发射方向信息中包括上行参考信号的信息比如另一个SRS的ID的情况下，第二确定单元102还可以被配置为将先前用于接收该上行参考信号的波束方向上的SSB作为第一非周期SRS资源的PL RS。可以将这种方式称为回退(fall back)方式，其示意图如图4所示。
在该示例中，第二确定单元102可以将重新确定的第一非周期SRS资源的PL RS作为第一非周期SRS资源所属的第一SRS资源集合中的其他非周期SRS资源的PL RS，也可以将其他非周期SRS资源的PL RS保持不变。例如，参照图3和图4，可以将SRS资源1的新的PL RS作为SRS资源0和SRS资源2至SRS资源M的PL RS，也可以保持SRS资源0和SRS资源2至SRS资源M的PL RS不变。M为正整数。至于采用哪一种方式，例如可以由基站和UE事先约定好。
可以看出，该示例不产生额外的信令开销，UE基于第一MAC CE信令本身可以确定出第一非周期SRS资源的新的PL RS。
在另一个示例中，基站将通过额外的MAC CE信令来帮助UE确定第一非周期SRS资源的新的PL RS。
在第一非周期SRS资源所在的第一SRS资源集合的PL RS为CSI-RS的情况下，第二确定单元102还被配置为从基站获取第二MAC CE信令，并基于第二MAC CE信令更新第一SRS资源集合的PL RS的传输配置指示(Transmission Configuration Indication，TCI)。具体地，第二MAC CE信令通过更新作为第一SRS资源集合的PL RS的CSI-RS的TCI，改变了该CSI-RS的下行波束发射方向，从而间接改变了第一SRS资源集合的PL RS，以使得改变后的第一SRS资源集合的PL RS能够适合于第一非周期SRS资源。该示例的示意图如图5所示，其中，第一MAC CE更新SRS资源1的波束发射方向。
类似地，第二确定单元102可以将改变后的第一SRS资源集合的PL RS应用于集合中的其他非周期SRS资源，也可以保持其他非周期SRS资源的PL RS不变。具体采用何种配置例如取决于基站与UE之间的事先约定。
在另一个示例中，例如，第一非周期SRS资源属于第一SRS资源集合，但是不同于第一SRS资源集合的第二SRS资源集合的PL RS更适合更新后的第一非周期SRS资源的波束发射方向，从而更适合作为第一非周期SRS资源的PL RS。在这种情况下，第二确定单元102还被配置为从基站获取第二MAC CE信令，该指令用于将第一非周期SRS资源转移到第二SRS资源集合，相应地，第二确定单元102将第二SRS资源集合的PL RS确定为第一非周期SRS资源的PL RS。该示例的示意图如 图6所示。
在该示例中，通过修改第一非周期SRS资源的集合从属关系，在保证SRS资源集合内的PL RS一致性的情况下更新了第一非周期SRS资源的PL RS。
在又一个示例中，例如，在载波聚合(Carrier Aggregation，CA)场景下，RRC信令中存在一个参数pathlossReferenceLinking，用于向UE指示某一个SRS资源集合的PL RS在哪一个服务小区上，一般是SpCell(special cell)和SCell(secondary cell)中之一，其中，SpCell只有一个，SCell可以有多个(例如，最多31个)。在本示例中，对该参数的使用功能进行了扩展，例如可以通过第二MAC CE信令来实现第一非周期SRS资源的PL RS到其他服务小区的链接。其中，第二MAC CE信令中可以包括一个SCell索引(index)，以指示第一非周期SRS资源的PL RS将被链接到对应的SCell。示例性地，第一非周期SRS资源所属的第一SRS资源集合的PL RS在SpCell上，但是在更新了第一非周期SRS资源的波束发射方向后，SpCell上的PL RS不再适用于第一非周期SRS资源，基站将发出第二MAC CE信令以将参数pathlossReferenceLinking调整到某一个SCell上。即，将第一非周期SRS资源的PL RS链接到另一服务小区上。注意，由于上述调整是通过pathlossReferenceLinking来实现的，因此，可以认为将第一SRS资源集合的PL RS链接到了另一服务小区。即，第一SRS资源集合中所有SRS资源的PL RS均链接到了另一服务小区；或者，可以保持第一SRS资源集合中其他SRS资源的PL RS仍在到原来的服务小区上。具体使用哪种方式例如可以由基站和UE事先约定好。
具体地，第一服务小区和第二服务小区均为载波聚合中的服务小区，第一非周期SRS资源属于第一SRS资源集合并且第一SRS资源集合的第一PL RS在第一服务小区上，第二MAC CE信令用于将第一PL RS链接到第二服务小区，其中，第二服务小区上的该第一PL RS更适合更新后的第一非周期SRS资源的波束发射方向，从而更适合作为第一非周期SRS资源的PL RS，第二确定单元102将第二服务小区上的该第一PL RS确定为第一非周期SRS资源的PL RS。该示例的示意图如图7所示，其中，通过第二MAC CE信令将SRS资源1的PL RS链接到第二服务小区，在第二服务小区中，该PL RS例如为SRS资源集合B的PL RS。 取决于基站与UE之间的事先约定，SRS资源集合A中的其他SRS资源的PL RS可以链接到第二服务小区，也可以保持不变。
类似地，在该示例中，通过用MAC CE信令修改第一非周期SRS资源的PL RS的服务小区链接关系，在利用已有信令的基础上更新了第一非周期SRS资源的PL RS。
应该注意，以上只是给出了重新确定波束发射方向被MAC CE信令更新的非周期SRS资源的PL RS的多种方法的示例，但是这并不是限制性的。
此外，在可以采用多种方法来重新确定第一非周期SRS资源的PL RS的情况下，可以为不同的方法设置不同的优先级别。示例性地，第二确定单元102可以按照如下优先顺序来选择用于重新确定第一非周期SRS资源的PL RS的方法：基于第二MAC CE信令确定；基于波束发射方向信息确定。即，在存在第二MAC CE信令的情况下，按照第二MAC CE信令的指示来确定第一非周期SRS资源的PL RS，否则基于波束发射方向信息来进行确定。应该理解，这并不是限制性的，也可以采用相反的优先顺序，或者由UE自行确定采用哪种方法。
另一方面，UE和基站可以约定使用固定的一种方法来确定第一非周期SRS资源的PL RS，例如，从上述多种方法中选择一种方法，并且仅使用这种方法来进行确定。在这种情况下，例如可以选择一种信令开销最小的方法，比如基于波束发射方向信息中包括的上行参考信号或下行参考信号的信息进行确定的方法。
综上所述，根据本实施例的电子设备100通过针对波束发射方向被第一MAC CE信令更新的第一非周期SRS资源更新其PL RS，能够为该第一非周期SRS资源配置适当的PL RS，从而准确地确定SRS的上行发射功率。
<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：第一确定单元201，被配置为针对波束发射方向被第一MAC CE信令更新的第一非周期SRS资源，确 定要用于UE重新确定第一非周期SRS资源的PL RS的方法；以及第二确定单元202，被配置为根据所确定的方法确定要进一步执行的操作。
其中，第一确定单元201和第二确定单元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。
与第一实施例中类似地，第一非周期SRS资源的新的PL RS可以以多种方法确定。
例如，第一确定单元201可以确定采用如下方法：由UE基于波束方向信息中的包括的上行参考信号或下行参考信号的信息来重新确定PL RS。该方法在第一实施例中已经详细描述，在此不再重复。在这种方式中，基站不需要再发送任何其他信令或执行其他操作，因此，第二确定单元202被配置为确定不执行另外的操作。
在另一个示例中，在第一非周期SRS资源所在的第一SRS资源集合的PL RS为CSI-RS的情况下，第一确定单元201可以确定采用如下方法：通过第二MAC CE信令更新该CSI-RS的TCI，以使其适合作为第一非周期SRS资源的PL RS。第二确定单元202被配置为生成并向UE发送包括该TCI的第二MAC CE信令。相应地，UE根据该第二MAC CE信令，将具有更新的TCI的CSI-RS作为第一非周期SRS资源的PL RS。可选地，第一SRS资源集合中的其他非周期SRS资源可以保持原来的PL RS，也可以改变为新的PL RS，这取决于例如基站与UE之间的事先 约定。可以看出，在采用该方法时，基站需要额外生成和发送第二MAC CE信令。
在另一个示例中，假设第一非周期SRS资源属于第一SRS资源集合，不同于第一SRS资源集合的第二SRS资源集合的PL RS适合作为第一非周期SRS资源的PL RS，则第一确定单元202所确定的方法可以包括：通过第二MAC CE信令将第一非周期SRS资源转移到第二SRS资源集合。这样，UE可以将第二SRS资源集合的PL RS确定为第一非周期SRS资源的PL RS。第二确定单元202被配置为生成并向UE发送第二MAC CE信令。
在另一个示例中，假设处于CA场景中，第一服务小区和第二服务小区为载波聚合中的服务小区，且在RRC信令中通过参数pathlossReferenceLinking指示了第一SRS资源集合的第一PL RS在哪一个小区上，比如在第一服务小区上。第一非周期SRS资源属于第一SRS资源集合，在通过第一MAC CE信令更新了第一非周期SRS资源的波束发射方向后，在第一服务小区上的第一PL RS已经不再适合作为第一非周期SRS资源的PL RS，同时，第一PL RS在第二服务小区上时适合作为第一非周期SRS资源的PL RS，则第一确定单元201可以确定采用如下方法：通过第二MAC CE信令将第一PL RS链接到第二服务小区。这样，UE可以将第二服务小区上的第一PL RS确定为第一非周期SRS资源的PL RS。第二确定单元202被配置为生成并向UE发送第二MAC CE信令。可选地，第一SRS资源集合中的其他非周期SRS资源的PL RS可以保持不变，也可以链接到第二服务小区，这取决于例如基站与UE之间的事先约定。
有关以上各个方法的详细细节可参考第一实施例中所述，在此不再重复。注意，与第一实施例中类似地，第一MAC CE信令和第二MAC CE信令也可以为同一条MAC CE信令。
作为一种方式，第一确定单元201可以根据各种因素确定采用多种方法中的一种，并且第二确定单元202可以根据所确定的方法确定要进一步执行的操作。例如，第一确定单元201可以根据如下中的一个或多个确定所述方法：第一MAC CE信令中的波束发射方向信息；各个SRS资源集合的PL RS；信令开销。例如，第一确定单元201可以根据这些因素中的一个或多个确定多种方法的优先顺序，并优先采用排在前面的 方法。
作为另一种方式，第一确定单元201可以固定地采用某一种方法，并且第二确定单元202根据该方法确定要进一步执行的操作。例如，该固定采用的方法具有良好的通用性、较小的信令开销等。例如，第一确定单元201可以固定采用UE基于波束方向信息中包括的上行参考信号或下行参考信号的信息来重新确定PL RS的方法，在这种情况下，甚至可以省略第一确定单元201和第二确定单元201，而在基站和UE侧之间进行约定即可。
综上所述，根据本实施例的电子设备200通过针对波束发射方向被第一MAC CE信令更新的第一非周期SRS资源更新其PL RS，能够为该第一非周期SRS资源配置适当的PL RS，从而准确地确定SRS的上行发射功率。
<第三实施例>
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9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：确定波束发射方向被第一MAC CE信令更新的第一非周期SRS资源(S11)；以及基于第一MAC CE信令中的第一非周期SRS资源的波束发射方向信息或者第二MAC CE信令，重新确定用于第一非周期SRS资源的PL RS(S12)。该方法可以在UE侧执行。
在一个示例中，在步骤S12中，可以基于波束发射方向信息中包括的下行参考信号或上行参考信号的信息来重新确定所述PL RS。在波束发射方向信息中包括下行参考信号的信息的情况下，可以将该下行参考信号作为第一非周期SRS资源的PL RS；在波束发射方向信息中包括上 行参考信号的信息的情况下，可以将上行参考信号所在的SRS资源集合的PL RS作为第一非周期SRS资源的PL RS。或者，在波束发射方向信息中包括下行参考信号的信息的情况下，可以将与下行参考信号具有QCL_TypeD关系的SSB作为第一非周期SRS资源的PL RS；在波束发射方向信息中包括上行参考信号的信息的情况下，可以将先前用于接收上行参考信号的波束方向上的SSB作为第一非周期SRS资源的PL RS。
在另一个示例中，在第一非周期SRS资源所在的第一SRS资源集合的PL RS为CSI-RS的情况下，在步骤S12中包括：从基站获取第二MAC CE信令，并基于第二MAC CE信令更新第一SRS资源集合的PL RS的TCI。
在另一个示例中，第一非周期SRS资源属于第一SRS资源集合，第二MAC CE信令用于将第一非周期SRS资源转移到不同于所述第一SRS资源集合的第二SRS资源集合，步骤S12还包括将第二SRS资源集合的PL RS确定为第一非周期SRS资源的PL RS。
在另一个示例中，针对CA场景，第一非周期SRS资源属于第一SRS资源集合且第一SRS资源集合的第一PL RS在第一服务小区上，第二MAC CE信令用于将第一PL RS链接到第二服务小区，步骤S12还包括将第二服务小区上的第一PL RS确定为第一非周期SRS资源的PL RS，其中，第一服务小区和第二服务小区为载波聚合中的服务小区。
此外，取决于实际配置，在一些示例中，可以将重新确定的第一非周期SRS资源的PL RS作为第一非周期SRS资源所属的集合中的其他非周期SRS资源的PL RS，也可以保持其他非周期SRS资源的PL RS不变。
此外，在步骤S12中，例如可以按照如下优先顺序来选择用于重新确定第一非周期SRS资源的PL RS的方法：基于第二MAC CE信令确定；基于波束发射方向信息确定。应该理解，这并不是限制性的。
图10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：针对波束发射方向被第一MAC CE信令更新的第一非周期SRS资源，确定要用于UE重新确定所述第一非周期SRS资源的PL RS的方法(S21)；以及根据所确定的方法确定要进一步执行的操作(S22)。该方法例如可以在基站侧执行。
UE重新确定所述第一非周期SRS资源的PL RS的方法已经在前文中给出了详细描述，在此不再重复。
此外，在步骤S21中例如可以根据如下中的一个或多个确定所述方法：第一MAC CE信令中的波束发射方向信息；各个SRS资源集合的PL RS；信令开销。
根据本申请的实施例的上述方法通过针对波束发射方向被第一MAC CE信令更新的第一非周期SRS资源更新其PL RS，能够为该第一非周期SRS资源配置适当的PL RS，从而准确地确定SRS的上行发射功率。
注意，上述各个方法可以结合或单独使用，其细节在第一至第二实施例中已经进行了详细描述，在此不再重复。
本公开内容的技术能够应用于各种产品。
例如，电子设备200可以被实现为各种基站。基站可以被实现为任何类型的演进型节点B(eNB)或gNB(5G基站)。eNB例如包括宏eNB和小eNB。小eNB可以为覆盖比宏小区小的小区的eNB，诸如微微eNB、微eNB和家庭(毫微微)eNB。对于gNB也可以由类似的情形。代替地，基站可以被实现为任何其他类型的基站，诸如NodeB和基站收发台(BTS)。基站可以包括：被配置为控制无线通信的主体(也称为基站设备)；以及设置在与主体不同的地方的一个或多个远程无线头端(RRH)。另外，各种类型的用户设备均可以通过暂时地或半持久性地执行基站功能而作为基站工作。
电子设备100可以被实现为各种用户设备。用户设备可以被实现为移动终端(诸如智能电话、平板个人计算机(PC)、笔记本式PC、便携式游戏终端、便携式/加密狗型移动路由器和数字摄像装置)或者车载终端(诸如汽车导航设备)。用户设备还可以被实现为执行机器对机器(M2M)通信的终端(也称为机器类型通信(MTC)终端)。此外，用户设备可以为安装在上述终端中的每个终端上的无线通信模块(诸如包括单个晶片的集成电路模块)。
[关于基站的应用示例]
(第一应用示例)
图11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11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11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。
基站设备820包括控制器821、存储器822、网络接口823以及无线通信接口825。
