具体实施方式
在下文中将结合附图对本发明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发明，在附图中仅仅示出了与根据本发明的方案密切相关的设备结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
图1示出了根据本公开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包括处理单元101，处理单元101被配置为至少从由预先确定的候选时频资源块构成的候选资源集合中选择用于初传和/或重传数据块的时频资源块。
其中，处理单元101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。
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用户设备。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。基站例如可以是eNB或gNB。
作为示例，处理单元101可以被配置为在侧行链路(sidelink)资源 选择模式2的场景下，选择用于初传和/或重传数据块的时频资源块。
在5G NR sidelink通信中，有两种资源选择方式，一种是基站对sidelink资源进行调度，称为资源选择模式1(mode 1)，另一种是UE自主选择资源，称为资源选择模式2(mode 2)。
图2是示出现有技术中的发送方用户设备在侧行链路资源选择模式2下进行时频资源选择的示意图。在下文中结合图2进行的描述中，有时将时频资源简称为资源。
发送方用户设备(简称为TX UE)首先通过资源感知过程，预先确定候选资源集合。如图2所示，在侧行链路资源选择模式2的资源选择过程中，数据包在n时刻触发了资源选择，则TX UE会使用感知窗口[n-T 0,n-T proc,0]期间感知的结果来排除资源。在[n-T 0,n-T proc,0]期间，TX UE会解码收到的来自其他用户设备的侧行链路控制信息(SCI)，通过解码SCI，获得已经被占用资源的信息，从而对这些资源进行排除；TX UE还会测量整个频带的参考信号接收功率(RSRP)强度，如果RSRP强度超过阈值，认为对应的频域资源被其他用户设备占用，从而对这些资源进行排除。完成资源排除之后剩余的资源可以作为可用的候选资源，候选资源的集合为可用的候选资源集合。接下来，TX UE使用随机资源选择机制，在候选资源集合中，选择一个或者多个资源进行传输。例如，TX UE会在候选资源集合中随机选择时域处于[n+T 1,n+T 2]间的资源作为初传和/或重传的资源。例如，如图2所示，TX UE选择用斜线填充的矩形框所表示的资源来作为所选资源。
在图2中，T 0是感知窗口的最大范围门限；T proc,0表示UE解码SCI并进行RSRP测量的处理时间；T 1表示从资源选择触发n到最早的候选资源之间，UE的处理时间；T2表示资源选择窗口的最大范围门限，其需要小于待传输数据块允许的时延大小。
上文中提到的预先确定的候选时频资源块可以是结合图2进行的描述中提及的完成资源排除之后剩余的资源，也可以是根据其他方式预先确定的时频资源块。
在下文中，主要结合侧行链路资源选择模式2的场景来描述从候选资源集合中选择用于初传和/或重传数据块的时频资源块。然而，本领域技术人员可以理解，下文中有关选择用于初传和/或重传数据块的时频资 源块的描述并不限于侧行链路资源选择模式2的场景，而是可以应用于4G或5G或其他通信方式中的、由用户设备来选择用于初传和/或重传数据块的时频资源块的其他场景。
作为示例，处理单元101可以被配置为将包括候选资源集合的资源选择窗口在时间维度上划分成预定数量的子资源选择窗口，以使得每个子资源选择窗口所占有的时间长度基本相同，以及从包括至少一个候选时频资源块的、位于时间上在前的至少一个子资源选择窗口中选择候选时频资源块来作为用于初传的时频资源块。
作为示例，在侧行链路资源选择模式2的场景下，预定数量可以是侧行链路控制信息(SCI)可以指示的时频资源块的个数，即，由SCI指示的可以预留的时频资源块的个数。例如，该预定数量可以是用于初传和重传数据块的次数之和，即用于重传数据块的次数加1。
图3是示出根据本公开实施例的将资源选择窗口在时间维度上划分成预定数量的子资源选择窗口的示例的图。在图3以及下面将要描述的其他附图中，用灰色填充的矩形块表示不可用时频资源块，而用白色填充的矩形块表示可用的候选时频资源块。图3中包括9个候选时频资源块，即候选资源集合中包括9个候选时频资源块。包括图3示出的所有时频资源块的窗口为资源选择窗口。假设预先配置SCI可以指示3个时频资源块，即预定数量Nmax＝3，因此，将图3所示的资源选择窗口在时间维度上划分成3个子资源选择窗口(子资源选择窗口1、子资源选择窗口2以及子资源选择窗口3)，使得每个子资源选择窗口所占有的时间长度基本相同(在图3示出的示例中，每个子资源选择窗口所占有的时间长度为5个时频资源块的时间长度)。在图3示出的示例中，子资源选择窗口1中包括3个候选时频资源块，子资源选择窗口2中包括2个候选时频资源块，以及子资源选择窗口3中包括4个候选时频资源块。
处理单元101可以从子资源选择窗口1中选择候选时频资源块作为用于初传的时频资源块(例如，图3中示出的、子资源选择窗口1中用虚线框起来的时频资源块)，这样可以保证对数据块的初传发生在资源选择窗口的前1/Nmax(1/3)处，从而可以减少初传数据块的时延；另外，例如，处理单元101可以从子资源选择窗口2中选择候选时频资源块作为用于初传的时频资源块，与从子资源选择窗口3中选择候选时频资源块作为用于初传的时频资源块相比，可以减少初传数据块的时延；因此， 根据本公开实施例的电子设备100可以减少初传数据块的时延，从而适用于某些对时延要求较高的服务，例如安全信息通知、车载游戏等服务等等。
本领域技术人员可以理解，图3仅是示例。在其他示例中，候选资源集合中包括的候选时频资源块的数量、预定数量Nmax以及候选时频资源块在资源选择窗口中的位置等均可以不同于图3中示出的示例。
在现有技术的通信方式(例如，侧行链路资源选择模式2)中，通常在候选资源集合中随机选择候选时频资源块来作为用于初传的时频资源块，随机选择可能使所选时频资源块处于资源选择窗口在时间上的后面部分，从而导致初传时延的增加。
然而，在根据本公开实施例的电子设备100中，通过在时间维度上对资源选择窗口进行划分并且在位于时间上在前的子资源选择窗口中选择用于初传的时频资源块，可以减少初传数据块的时延。
作为示例，处理单元101还可以被配置为从资源选择窗口中的在时间上位于用于初传的时频资源块之后的候选时频资源块当中，选择满足预定条件的候选时频资源块作为用于重传的时频资源块。优选地，处理单元101还可以被配置为从资源选择窗口中的在时间上位于紧挨用于初传的时频资源块之后的候选时频资源块当中，选择满足预定条件的候选时频资源块作为用于重传的时频资源块。
例如，在5G NR sidelink通信场景下，有两种资源重传模式：盲重传和基于HARQ-ACK的重传。其中盲重传可以在没有接收到任何反馈信息下，使用预留资源对同一个数据块(例如，传输块(TB))进行重复发送。在基于HARQ-ACK反馈信息的重传方式下，发送方UE在接收到NACK(否定应答)信息后，使用预留的资源进行重传，由于发送方UE需要等待ACK/NACK信息的反馈，因此两次资源传输之间要满足Z＝a+b的时间间隔，其中a表示初始PSSCH(物理侧行链路共享信道)传输结束最后一个符号到对PSSCH进行反馈的PSFCH(物理侧行链路反馈信道)开始传输第一个符号之间的时间间隔，b表示PSFCH的接收时间加上重传的准备时间。
例如，在基于混合自动重传请求确认(HARQ-ACK)重传数据块的情况下，满足预定条件可以指的是存在两次数据的传输间隔至少要满足 Z＝a+b的条件的候选时频资源块来作为用于重传的时频资源块。
例如，在基于盲重传来重传数据块的情况下，满足预定条件可以指的是能在资源选择窗口中成功预留候选时频资源块来作为用于重传的时频资源块。
用于重传的时频资源块可以与用于初传的时频资源块位于同一子资源选择窗口中，也可以位于与用于初传的时频资源块所位于的子资源选择窗口不同的子资源选择窗口中。
例如，在Nmax＝3的情况下，假设在子资源选择窗口1选择出用于初传的时频资源块。并且假设在子资源选择窗口1中存在满足上述预定条件的2个候选时频资源块的情况下，将这2个候选时频资源块作为用于重传的时频资源块。那么，用于初传的时频资源块和用于2次重传的时频资源块均位于子资源选择窗口1中，从而可以减少重传数据块的时延。另外，例如，即使用于重传的时频资源块不位于子资源选择窗口1中而是位于子资源选择窗口2中，与从资源选择窗口3中随机选择出用于重传的时频资源块相比，也可以减少重传数据块的时延。
作为示例，处理单元101可以被配置为：将包括候选资源集合的资源选择窗口划分成预定数量的子资源选择窗口，以使得每个子资源选择窗口中包括的候选时频资源块的数量基本相同，以及在位于时间上最前的子资源选择窗口中选择候选时频资源块作为用于初传的时频资源块。
作为示例，在侧行链路资源选择模式2的场景下，预定数量可以是侧行链路控制信息(SCI)可以指示的时频资源块的个数，即，由SCI指示的可以预留的时频资源块的个数。例如，该预定数量可以是用于初传和重传数据块的次数之和，即用于重传数据块的次数加1。
图4是示出根据本公开实施例的按照候选时频资源块的数量对资源选择窗口进行划分的示例的图。图4中的资源选择窗口与图3中的资源选择窗口相同，这里不再累述。如图4所示，将资源选择窗口划分成3个子资源选择窗口(子资源选择窗口1’、子资源选择窗口2’以及子资源选择窗口3’)，使得每个子资源选择窗口中包括的候选时频资源块的数量相同(在图4示出的示例中，每个子资源选择窗口包括3个候选时频资源块)。
处理单元101从子资源选择窗口1’中选择候选时频资源块作为用于 初传的时频资源块(例如，图4中示出的、子资源选择窗口1’中用虚线框起来的时频资源块)，能够减少初传数据块的时延，从而根据本公开实施例的电子设备100适用于某些对时延要求较高的服务，例如安全信息通知、车载游戏等服务等等。
作为示例，处理单元101还可以被配置为从资源选择窗口中的在时间上位于用于初传的时频资源块之后的候选时频资源块当中，选择满足预定条件的候选时频资源块作为用于重传的时频资源块。优选地，处理单元101还可以被配置为从资源选择窗口中的在时间上位于紧挨用于初传的时频资源块之后的候选时频资源块当中，选择满足预定条件的候选时频资源块作为用于重传的时频资源块。该预定条件与上文中描述的预定条件相同，这里不再累述。用于重传的时频资源块可以与用于初传的时频资源块位于同一子资源选择窗口中，也可以位于与用于初传的时频资源块所位于的子资源选择窗口不同的子资源选择窗口中。例如，在Nmax＝3的情况下，假设在子资源选择窗口1’中存在满足上述预定条件的2个候选时频资源块的情况下，将这2个候选时频资源块作为用于重传的时频资源块。那么，用于初传的时频资源块和用于2次重传的时频资源块均位于子资源选择窗口1’中，从而可以减少重传数据块的时延。另外，例如，即使用于重传的时频资源块不位于子资源选择窗口1’中而是位于子资源选择窗口2’中，与从资源选择窗口3’中随机选择出用于重传的时频资源块相比，也可以减少重传数据块的时延。
作为示例，在Nmax＝3的情况下，每个电子设备从子资源选择窗口1’中选择用于初传的时频资源块、以及在子资源选择窗口2’和子资源选择窗口3’中分别选择用于重传的时频资源块，可以避免不同的电子设备选择资源时的碰撞。
作为示例，除了预先确定的候选时频资源块之外，候选资源集合还包括不同于预先确定的候选时频资源块所在的预先配置的资源池的异常资源池中的一个或多个候选时频资源块，以及资源选择窗口还包括异常资源池中的一个或多个候选时频资源块。
图5是示出根据本公开实施例的资源选择窗口还包括异常资源池中的一个或多个候选时频资源块的示例的图。图5中的用白色填充的9个时频资源块对应于图3和图4中示出的9个候选时频资源块，以及图5中的正常资源池对应于图3和图4中示出的资源选择窗口。图5中的用 黑色填充的3个时频资源块是异常资源池中的可用的候选时频资源块，以及图5中的用灰色填充的时频资源块为不可用的时频资源块。与结合图3和图4描述的示例相比，在图5中，候选资源集合还包括不同于正常资源池的异常资源池中的3个候选时频资源块，以及资源选择窗口还包括异常资源池中的3个候选时频资源块。
异常资源池能够丰富候选资源集合的组成，能够辅助对用于初传和/或重传时频资源块的选择，即能够增加用于初传和/或重传数据块的时频资源块的可选择性；此外，可以根据不同数据服务的特性，定制异常资源池；另外，由于异常资源池中的候选时频资源块在时间上可能位于正常资源池中的候选时频资源块之前，因此，可以进一步减少初传和/或重传数据块的时延。例如，在图5的示例中，将资源选择窗口在时间维度上划分成子资源选择窗口1、子资源选择窗口2以及子资源选择窗口3，使得每个子资源选择窗口所占有的时间长度基本相同(在图5示出的示例中，每个子资源选择窗口所占有的时间长度为5个时频资源块的时间长度)。其中，子资源选择窗口1中包括4个候选时频资源块，子资源选择窗口2中包括3个候选时频资源块，以及子资源选择窗口3中包括5个候选时频资源块。由于图5中以虚线框起来的、位于异常资源池中的候选时频资源块在时间上位于正常资源池中的候选时频资源块之前，因此，选择该候选时频资源作为用于初传的时频资源块可以进一步减少初传的时延。关于图5中的示例中的用于重传的时频资源块的选择，除了资源选择窗口还包括异常资源池中的一个或多个候选时频资源块之外，其他描述均可以参考关于图3的示例的描述，这里不再累述。
图6是示出根据本公开实施例的资源选择窗口还包括异常资源池中的一个或多个候选时频资源块的另一示例的图。图6中示出的正常资源池和异常资源池对应于图5中示出的正常资源池和异常资源池。在图6示出的示例中，将包括异常资源池中的一个或多个候选时频资源块的资源选择窗口按照候选时频资源块的数量划分成3个子资源选择窗口(子资源选择窗口1’、子资源选择窗口2’以及子资源选择窗口3’)，使得每个子资源选择窗口中包括的候选时频资源块的数量相同(在图6示出的示例中，每个子资源选择窗口包括4个候选时频资源块)。
处理单元101可以从子资源选择窗口1’中选择候选时频资源块作为用于初传的时频资源块(例如，图6中示出的、子资源选择窗口1’中用 虚线框起来的时频资源块)，从而可以进一步减少初传数据块的时延。
关于图6中的示例中的用于重传的时频资源块的选择，除了资源选择窗口还包括异常资源池中的一个或多个候选时频资源块之外，其他描述均可以参考关于图4的示例的描述，这里不再累述。
在上文中提及，在基于HARQ-ACK重传数据块的情况下，两次数据传输之间要满足Z＝a+b的时间间隔，也就是说，需要从候选资源集合中选择满足时间间隔Z的时频资源块作为用于重传的时频资源块。然而，这样可能无法满足某些时延要求比较严格的业务的需求。
处理单元101可以被配置为在基于HARQ-ACK重传数据块的两个时频资源块之间，对数据块进行至少一次盲重传，以降低传输时延，从而满足某些时延要求比较严格的业务的需求，另外，在使用盲重传和基于HARQ-ACK的重传结合的混合重传机制中，由于盲重传不需要满足时间间隔Z的要求，因此提高了在相同的时间内传输数据块的次数，由此提高传输数据块的可靠性。
作为示例，处理单元101可以被配置为在基于HARQ-ACK重传数据块的两个时频资源块之间，利用不同于预先确定的候选时频资源块所在的预先配置的资源池的异常资源池中的至少一个候选时频资源块来对数据块进行至少一次盲重传。
如上所述，由于在基于HARQ-ACK重传数据块的两个时频资源块之间对数据块进行至少一次盲重传，因此，能够减少重传的时延并增加传输的可靠性。
此外，由于可以利用异常资源池中的候选时频资源块来进行盲重传，因此，增加了用于盲重传数据块的时频资源块的可选择性。
在上文中提及，在基于HARQ-ACK重传数据块的情况下，两次数据传输之间要满足Z＝a+b的时间间隔，也就是说，需要从候选资源集合中选择满足时间间隔Z的时频资源块作为用于重传的时频资源块。然而，在某些情况下，可能在候选资源集合中找不到可以满足时间间隔Z的时频资源(例如，用于初传的时频资源块和用于重传的时频资源块之间无法满足时间间隔Z，以及/或者用于重传的时频资源块之间无法满足时间间隔Z)。现有技术中规定：如果在候选资源集合中找不到可以满足时间间隔Z的时频资源，可以通过发送方UE的行为自主解决该问题，但是 用于重传的时频资源块必须满足上述时间间隔为Z的要求。然而，现有技术中并没有确认发送方UE的具体行为。在下文中，将描述根据本公开实施例的电子设备100在候选资源集合中找不到可以满足时间间隔Z的时频资源的情况下的具体行为。
作为示例，处理单元101可以被配置为在候选资源集合中不存在满足基于HARQ-ACK重传数据块时的预定重传时间间隔的候选时频资源块的情况下，通过提高参考信号接收功率RSRP的阈值来增加候选资源集合中的候选时频资源块的数量，以从增加后的候选资源集合中选择满足预定重传时间间隔的候选时频资源块来重传数据块，其中，处理单元101可以被配置为在用于预先确定候选时频资源块的资源感知阶段，将具有低于阈值的RSRP的时频资源块作为候选时频资源块包括在候选资源集合中。
例如，预定重传时间间隔为上文中提到的时间间隔Z。
在例如结合图2描述的资源感知阶段，电子设备100通过将候选时频资源块的RSRP测量值与阈值进行比较，将具有低于阈值的RSRP的时频资源块作为候选时频资源块包括在候选资源集合中而将具有高于或等于阈值的RSRP的时频资源块从候选资源集合中排除，由此筛选出候选时频资源块。因此，通过提高RSRP的阈值，可以增加候选资源集合中包括的候选时频资源块的数量，由此可能从增加后的候选资源集合中选择出满足预定重传时间间隔的候选时频资源块。
作为示例，处理单元101可以被配置为在候选资源集合中不存在满足基于HARQ-ACK重传数据块时的预定重传时间间隔的候选时频资源块的情况下，从不同于预先确定的候选时频资源块所在的预先配置的资源池的异常资源池中的至少一个候选时频资源块当中选择满足预定重传时间间隔的候选时频资源块来重传数据块。
异常资源池中的至少一个候选时频资源块增加了可用的候选时频资源块的数量，因此，可能从异常资源池中选择出满足预定重传时间间隔的候选时频资源块。
作为示例，处理单元101可以被配置为在候选资源集合中不存在满足基于HARQ-ACK重传数据块时的预定重传时间间隔的候选时频资源块的情况下，通过在数据传输的控制信息中增加有关重传数据块的方式 的字段来更改重传数据块的方式，其中，字段用于指示基于HARQ-ACK、盲重传以及包括HARQ-ACK和盲重传的混合重传中之一来重传数据块。
例如，在候选资源集合中不存在满足基于HARQ-ACK重传数据块时的预定重传时间间隔的候选时频资源块的情况下，处理单元101可以通过上述有关重传数据块的方式的字段来指示当前重传方式的改变(例如，可以使用两个比特来表示当前重传是基于HARQ-ACK、盲重传还是混合重传)。在候选资源集合中不存在满足基于HARQ-ACK重传数据块时的预定重传时间间隔的候选时频资源块的情况下，通过改变当前重传方式(例如，改变为盲重传或者混合重传)，可以保证正常的数据传输，从而减少传输时延。
作为示例，上述控制信息为SCI。例如，在SCI中增加有关重传数据块的方式的字段来更改重传数据块的方式。
本领域技术人员可以理解，上文中描述的选择用于初传数据块的时频资源块的方案、选择用于重传数据块的时频资源块的方案、在候选资源集合中不存在满足基于HARQ-ACK重传数据块时的预定重传时间间隔的候选时频资源块的情况下来选择用于重传数据块的时频资源块的方案可以独立存在，也可以相互结合。
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7示出了根据本公开的一个实施例的用于无线通信的方法700的流程图。方法700在步骤S702开始。在步骤S704中，至少从由预先确定的候选时频资源块构成的候选资源集合中选择用于初传和/或重传数据块的时频资源块。方法700在步骤S706结束。
该方法例如可以通过上文所描述的电子设备100来执行，其具体细节可参见以上相应位置的描述，在此不再重复。
本公开内容的技术能够应用于各种产品。
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8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8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8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。
控制器821可以为例如CPU或DSP，并且操作基站设备820的较高层的各种功能。例如，控制器821根据由无线通信接口825处理的信号中的数据来生成数据分组，并经由网络接口823来传递所生成的分组。控制器821可以对来自多个基带处理器的数据进行捆绑以生成捆绑分组，并传递所生成的捆绑分组。控制器821可以具有执行如下控制的逻辑功能：该控制诸如为无线资源控制、无线承载控制、移动性管理、接纳控 制和调度。该控制可以结合附近的eNB或核心网节点来执行。存储器822包括RAM和ROM，并且存储由控制器821执行的程序和各种类型的控制数据(诸如终端列表、传输功率数据以及调度数据)。
网络接口823为用于将基站设备820连接至核心网824的通信接口。控制器821可以经由网络接口823而与核心网节点或另外的eNB进行通信。在此情况下，eNB 800与核心网节点或其他eNB可以通过逻辑接口(诸如S1接口和X2接口)而彼此连接。网络接口823还可以为有线通信接口或用于无线回程线路的无线通信接口。如果网络接口823为无线通信接口，则与由无线通信接口825使用的频带相比，网络接口823可以使用较高频带用于无线通信。
无线通信接口825支持任何蜂窝通信方案(诸如长期演进(LTE)和LTE-先进)，并且经由天线810来提供到位于eNB 800的小区中的终端的无线连接。无线通信接口825通常可以包括例如基带(BB)处理器826和RF电路827。BB处理器826可以执行例如编码/解码、调制/解调以及复用/解复用，并且执行层(例如L1、介质访问控制(MAC)、无线链路控制(RLC)和分组数据汇聚协议(PDCP))的各种类型的信号处理。代替控制器821，BB处理器826可以具有上述逻辑功能的一部分或全部。BB处理器826可以为存储通信控制程序的存储器，或者为包括被配置为执行程序的处理器和相关电路的模块。更新程序可以使BB处理器826的功能改变。该模块可以为插入到基站设备820的槽中的卡或刀片。可替代地，该模块也可以为安装在卡或刀片上的芯片。同时，RF电路827可以包括例如混频器、滤波器和放大器，并且经由天线810来传送和接收无线信号。
如图8所示，无线通信接口825可以包括多个BB处理器826。例如，多个BB处理器826可以与eNB 800使用的多个频带兼容。如图8所示，无线通信接口825可以包括多个RF电路827。例如，多个RF电路827可以与多个天线元件兼容。虽然图8示出其中无线通信接口825包括多个BB处理器826和多个RF电路827的示例，但是无线通信接口825也可以包括单个BB处理器826或单个RF电路827。
