Description

传输信号的方法和装置
本申请要求于2017年3月24日提交中国专利局、申请号为201710182587.6、申请名称为“传输信号的方法和装置”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
本申请涉及通信领域,并且更具体地,涉及一种传输信号的方法和装置。
背景技术
在5G新无线接入(New Radio Access,NR)系统的研究阶段(Study Item,SI),提出NR主同步信号(NR-Primary Synchronization Signal,NR-PSS),NR辅同步信号(NR-Secondary Synchronization Signal,NR-SSS)和NR广播信道(NR-Physical Broadcast Channel,NR-PBCH)在一个同步信号块(Synchronization Signal block,SS block)里发送。在单波束和多波束的情况下,NR-PSS、NR-SSS和NR-PBCH都以时分复用(Time Division Multiplexing,TDM)的方式在相邻的符号上发送。一个或多个上述的SS block构成一个同步信号脉冲(SS burst),一个或多个SS burst构成一个同步信号脉冲集(SS burst set),SS burst set周期性地发送。
NR-PSS、NR-SSS和NR-PBCH具有不同的覆盖能力及可靠性,因此可能需要对这些信号进行不同的处理,例如,波束赋形或功率提升等。上述方案会导致各种处理在相邻符号间频繁切换。另外,在上述方案中,每一种信号的搜索时间较长。这些问题都会影响系统的性能。
因此,亟需一种适合NR的同步信号的传输方案,以提升系统的性能。
发明内容
本申请提供一种传输信号的方法和装置,能够提升系统的性能。

在本申请实施例中,在发送同步信号块中的信号时,网络设备将至少一种信号与其他信号在不相邻的符号上发送。也就是说,将至少一种信号与其他信号分离。这样,一方面,在一块集中发送的信号种类减少,每一种信号的搜索时间缩短;另一方面,这种分离发送的方式便于对分离的两部分信号分别进行不同的处理。因此,本申请实施例的技术方案能够提升系统的性能。
在一些可能的实现方式中,发送该多个同步信号块中的信号,包括:
将该每个同步信号块中的至少一种信号与同一同步信号块中的其他信号在不同的时隙上发送。
在一些可能的实现方式中,发送该多个同步信号块中的信号,包括:

PBCH与PSS、SSS分离,在另一个时隙上发送,这样可以对PBCH进行额外的处理,例如功率提升,以增强PBCH的性能。另外,PSS的搜索时间也相比PSS、SSS和PBCH一块连续发送的方式缩短。
在一些可能的实现方式中,一种信号在一个时隙内发送既可以采用连续方式也可以采用非连续方式,多种信号在一个时隙内发送既可以采用交错方式,也可以采用非交错方式。

将该多个同步信号块中的多个该第一同步信号在第一时隙内连续或非连续发送,将该多个同步信号块中的多个该第二同步信号和多个该广播信号在第二时隙和第三时隙内交错发送。
将PSS在一个时隙内连续发送可以缩短终端设备搜索同步信号时间,从而缩短时频同步的时长,减少终端设备的接入时延。将SSS和PBCH交错发送可以把SSS用作PBCH的解调参考信号。
在一些可能的实现方式中,该每个同步信号块中的信号包括该第一同步信号、该第二同步信号、第三同步信号和该广播信号;
发送该多个同步信号块中的信号,包括:

具体实施方式
下面将结合附图,对本申请中的技术方案进行描述。
图1给出了本申请实施例应用的一种网络系统的示意图。如图1所示,网络系统100可以包括网络设备102以及终端设备104、106、108、110、112和114,其中,网络设备与终端设备之间通过无线连接。应理解,图1仅以网络系统包括一个网络设备为例进行说明,但本申请实施例并不限于此,例如,系统还可以包括更多的网络设备;类似地,系统也可以包括更多的终端设备。
本说明书结合终端设备描述了各个实施例。终端设备也可以指用户设备(User Equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)网络中的终端设备等。
作为示例而非限定,在本申请实施例中,该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能首饰等。
本说明书结合网络设备描述了各个实施例。网络设备可以是用于与终端设备通信的设备,该网络设备可以是全球移动通讯(Global System of Mobile communication,GSM)或码分多址(Code Division Multiple Access,CDMA)中的基站(Base Transceiver Station,BTS),也可以是宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统中的基站(NodeB,NB),还可以是长期演进(Long Term Evolution,LTE)系统中的演进型基站(Evolutional Node B,eNB或eNodeB),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,或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等。
另外,在本申请实施例中,网络设备为小区提供服务,终端设备通过该小区使用的传输资源(例如,频域资源,或者说,频谱资源)与网络设备进行通信,该小区可以是网络设备(例如基站)对应的小区,小区可以属于宏基站,也可以属于小小区(small cell)对应的基站,这里的小小区可以包括:城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等,这些小小区具有覆盖范围小、发射功率低的特点,适用于提供高速率的数据传输服务。另外,该小区还可以是超小区(Hypercell)。Hypercell采用用户为中心的无蜂窝无线接入(User Centric No Cell Radio Access,UCNC)技术,即终端设备不再接入某一个固定的物理收发结点(Transmit Reception Point,TRP),而是接入一个包含一组TRP的逻辑实体来获得服务,这种逻辑实体可以称为Hypercell。Hypercell的边界是灵活的,可以根据网络负载、用户分布的变化而变化。Hypercell内的所有TRP对于终端设备都是透明的,终端设备只需要根据Hypercell ID接入,就可以获得Hypercell内TRP的服务,而不再固定与某个TRP连接。
图2示出了目前提出的同步与广播信道的示意图。如图2所示,在每一个SS block里,NR-PSS、NR-SSS和NR-PBCH映射在时间连续的正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号上。多个连续的SS blocks构成一个SS burst,多个SS bursts尽量连续发送。由于每一个SS block均由连续的OFDM符号组成,NR-PSS、NR-SSS和NR-PBCH在时域资源上间隔分布,一方面使得终端设备搜索NR-PSS,做时频符号同步的时间拉长,另一方面也不便于对不同信号进行不同的处理,从而影响系统的性能。
本申请实施例提供了一种适合NR的信号传输方案,能够提升系统的性能。下面对本申请实施例的技术方案进行详细描述。
图3示出了本申请一个实施例的传输信号的方法的示意性流程图。图3中的网络设备可以为图1中的网络设备102;终端设备可以为图1中的终端设备104、106、108、110、112和114中的终端设备。当然,实际系统中,网络设备和终端设备的数量可以不局限于本实施例或其他实施例的举例,以下不再赘述。
310,网络设备生成多个同步信号块,其中,该多个同步信号块中的每个同步信号块包括第一同步信号、第二同步信号和广播信号。
在本申请实施例中,第一同步信号和第二同步信号为通信系统中使用的两种同步信号,例如,第一同步信号可以为NR-PSS,第二同步信号可以为NR-SSS。另外,第一同步信号和第二同步信号可以分别具有目前的PSS和SSS的功能。例如,第一同步信号可以用于确定OFDM符号定时、频率同步、时隙定时和小区组内的小区ID;第二同步信号可以用于确定帧定时、小区组等,但本申请实施例对此并不限定。换句话说,第一同步信号和第二同步信号也可以具有与目前的PSS和SSS不同的功能。另外,第一同步信号和第二同步信号可以采用分别与目前的PSS和SSS相同或不同的序列,本申请实施例对此也不限定。
可选地,第一同步信号和第二同步信号可以采用比目前的PSS和SSS更长的序列。例如,该更长的序列可以是一个长序列,或者是由相同或不同的序列连接形成的序列,这 些相同或不同的序列的长度可以相同或不同。
在本申请的各种实施例中,为了便于描述,以第一同步信号为PSS,第二同步信号为SSS举例说明,但本申请实施例对此并不限定。
在本申请实施例中,广播信号可以具有与目前的PBCH相同或不同的功能,本申请实施例对此也不限定。可选地,广播信号可以携带主要的系统信息,例如主信息块(Master Information Block,MIB)。
在本申请实施例中,同步信号块中的信号可以包括第一同步信号、第二同步信号和广播信号。在一些实施方式中,还可以包括其他信号,例如,另外的同步信号(第三同步信号)、用于传输除了广播信号中传输的系统信息外的其他系统信息的系统信号或者控制信号等。
网络设备分别生成同步信号块中的各种信号,然后通过相应的传输资源发送这些信号。
320,网络设备发送该多个同步信号块中的信号,其中,每个同步信号块中的至少一种信号与同一同步信号块中的其他信号在不相邻的符号上发送。
如上所述,本申请实施例中的同步信号块包括至少三种信号。在发送该同步信号块中的信号时,网络设备将至少一种信号与其他信号在不相邻的符号上发送。也就是说,将至少一种信号与其他信号分离。这样,一方面,在一块集中发送的信号种类减少,每一种信号的搜索时间缩短;另一方面,这种分离发送的方式便于对分离的两部分信号分别进行不同的处理。因此,本申请实施例的技术方案能够提升系统的性能。
可选地,在本申请一个实施例中,可以将同步信号块中的至少一种信号与同一同步信号块中的其他信号在不同的时隙上发送。
具体而言,在本实施例中,将同步信号块中的信号分离到不同的时隙上发送,即,一部分信号在一个时隙上发送,另一部分信号在另一个时隙上发送。
应理解,在本申请各种实施例中,符号和时隙表示传输信号的时域资源的不同粒度的单元,它们可以具有目前通信系统中的含义,也可以具有未来通信系统中的含义。另外,若在未来通信系统中它们的名称发生了改变,它们也可以变换为未来通信系统中的名称。
可选地,在本申请一个实施例中,可以将多个同步信号块中的多个该第一同步信号和多个该第二同步信号在第一时隙内交错发送,将该多个同步信号块中的多个该广播信号在第二时隙上连续或非连续发送。
应理解,本申请各种实施例并不限定相应信号在时隙内发送的方式,例如,一种信号在一个时隙内发送既可以采用连续方式也可以采用非连续方式,多种信号在一个时隙内发送既可以采用交错方式,也可以采用非交错方式。
例如,如图4所示,同步信号块包括PSS、SSS和PBCH,多个同步信号块中的PSS和SSS在时隙i内交错发送,PBCH在时隙j内连续发送。
在图4中,PBCH与PSS、SSS分离,在另一个时隙上发送,这样可以对PBCH进行额外的处理,例如功率提升(power boosting),以增强PBCH的性能。另外,PSS的搜索时间也相比PSS、SSS和PBCH一块连续发送的方式缩短。
一个同步信号块中的PSS、SSS和PBCH可以采用同样的波束发送,不同的同步信号块可以对应不同的波束,但本申请实施例对此并不限定。
应理解,对于图4还可以做一些变换,例如,PBCH也可以在时隙j内非连续发送,PSS和SSS的位置也可以互换等等,这些变换也应作为本申请的实施例。以下为了简洁,对于这些类似的变换不再一一赘述。
可选地,在本申请一个实施例中,可以将多个同步信号块中的多个该第一同步信号和多个该第二同步信号在第一时隙内交错发送,将该多个同步信号块中的多个该广播信号在第二时隙和第三时隙上连续或非连续发送。
例如,如图5所示,多个同步信号块中的PSS和SSS在时隙i内交错发送,PBCH在时隙j和时隙p内连续发送,其中,一个同步信号块的PSS和SSS可以采用宽波束发送,PBCH可以采用两个窄波束发送,以提升PBCH的覆盖能力。
可选地,在本申请一个实施例中,可以将多个同步信号块中的多个该第一同步信号在第一时隙内连续或非连续发送,将该多个同步信号块中的多个该第二同步信号和多个该广播信号在第二时隙和第三时隙内交错发送。
例如,如图6所示,多个同步信号块中的PSS在时隙i内连续发送,SSS和PBCH在时隙j内交错发送。将PSS在一个时隙内连续发送可以缩短终端设备搜索同步信号时间,从而缩短时频同步的时长,减少终端设备的接入时延。将SSS和PBCH交错发送可以把SSS用作PBCH的解调参考信号。
在上述各实施例中,同步信号块包括两种同步信号和广播信号。可选地,根据系统需要,同步信号块还可以包括更多的信号。例如,同步信号块还可以包括第三同步信号、系统信号或者控制信号,下面分别进行说明。
可选地,在本申请一个实施例中,同步信号块中的信号包括该第一同步信号、该第二同步信号、第三同步信号和该广播信号。该第三同步信号可以是根据系统需要新引入的额外的同步信号,该第三同步信号可以具有与该第一同步信号和该第二同步信号不同的功能,还可以与该第一同步信号和该第二同步信号共同实现同步和其他功能。例如,该第三同步信号可用于识别同步信号块时序序号(SS block time index),也可用于识别一个同步信号块配置的多个天线端口,即用于识别多个天线端口对应的多个波束,本申请实施例对该第三同步信号的作用不做限定。在这种情况下,可以将多个同步信号块中的多个该第一同步信号、多个该第二同步信号和多个该第三同步信号在第一时隙内交错发送,将该多个同步信号块中的多个该广播信号在第二时隙上连续或非连续发送。
例如,如图7所示,同步信号块包括PSS、SSS、TSS和PBCH,其中,TSS表示第三同步信号,多个同步信号块中的PSS、SSS和TSS在时隙i内交错发送,PBCH在时隙j内连续发送。
与图4类似,将PBCH分离在另一个时隙上发送,这样可以对PBCH进行额外的处理,例如功率提升(power boosting),以增强PBCH的性能。另外,与图5类似,还可以将PBCH采用多个窄波束发送,以提升PBCH的覆盖能力。
可选地,在本申请一个实施例中,同步信号块中的信号包括该第一同步信号、该第二同步信号、该广播信号和系统信号。在这种情况下,可以将多个同步信号块中的多个该第一同步信号、多个该第二同步信号和多个该广播信号在第一时隙内交错发送,将该多个同步信号块中的多个该系统信号在第二时隙上连续或非连续发送。
在本申请实施例中,广播信号可以携带主要的系统信息,例如MIB;再采用另外的 信号,系统信号,传输其他系统信息。
例如,如图8所示,同步信号块包括PSS、SSS、PBCH和系统信息(system information,SI),其中SI表示其他系统信息,多个同步信号块中的PSS、SSS和PBCH在时隙i内交错发送,SI在时隙j内连续发送,这样可以对SI进行额外的处理。
可选地,在本申请一个实施例中,该同步信号块中的信号包括该第一同步信号、该第二同步信号、该广播信号和控制信号。在这种情况下,可以将多个同步信号块中的多个该第一同步信号、多个该第二同步信号和多个该广播信号在第一时隙内交错发送,将该多个同步信号块中的多个该控制信号在第二时隙上连续或非连续发送。
在本申请实施例中,广播信号可以携带主要的系统信息,例如MIB;再采用另外的信号,控制信号,传输其他系统信息。
例如,如图9所示,同步信号块包括PSS、SSS、PBCH和控制信道(control channel,CCH),其中CCH表示其他系统信息,多个同步信号块中的PSS、SSS和PBCH在时隙i内交错发送,CCH在时隙j内连续发送,这样可以对CCH进行额外的处理。
应理解,本申请实施例并不限定同步信号块中的信号的数量,在同步信号块包括更多的信号的情况下,可以在上述各种实施例的分离方式的基础上进行类推,例如,将一种或多种信号与其他信号分离发送,这也应涵盖在本申请实施例的范围之内。
针对上述各种同步信号块的构造和传输方式,终端设备相应地进行信号接收,即,检测同步信号块中的信号,获取同步信号块中的信号,并进行后续的处理。终端设备的接收与网络设备的发送相对应,因此不再赘述。
以上描述的各种实施例中,同步信号块都包括广播信号,这些实施例的技术方案可以应用于单机(standalone)场景。在Standalone场景中,NR系统直接接入核心网,不需要依附另一系统发送辅助接入信号。在非单机(Non-standalone)场景中,NR系统需要依附于另一系统接入核心网,Non-standalone NR系统最少可只提供空口的相关传输。针对Non-standalone场景,本申请实施例也提供了传输同步信号块中信号的方案,下面进行详细描述。应理解,除以下描述外,下述各实施例还可以参考前述各实施例中的描述,以下为了简洁,不再赘述。
图10示出了本申请另一个实施例的传输信号的方法的示意性流程图。
1010,网络设备生成多个同步信号块,其中,该多个同步信号块中每个同步信号块包括第一同步信号和第二同步信号、且不包括广播信号。
在本申请实施例中,同步信号块中不包括广播信号。这样,同步信号块中的信号数量减少,每一种信号的搜索时间缩短。
由于同步信号块中不包括广播信号,本申请实施例的技术方案可以应用于Non-standalone场景,或双连接的辅基站系统,或载波聚合系统的辅载波上,广播信号可以从被锚上(anchor)的系统或载波上发送,从而节省该系统或载波的开销。
1020,网络设备发送该多个同步信号块中的信号。
网络设备分别生成同步信号块中的各种信号,然后通过相应的传输资源发送这些信号。
可选地,在本申请一个实施例中,可以将该多个同步信号块中的多个该第一同步信号在第一时隙内连续或非连续发送。
在一个时隙内发送多个同步信号块中的多个第一同步信号,这样可以缩短第一同步信号的搜索时间。
可选地,在本申请一个实施例中,可以将该多个同步信号块中的多个该第二同步信号在第二时隙内连续或非连续发送。
也就是说,多个同步信号块中的多个第一同步信号和多个第二同步信号可以分别在两个时隙中发送。
例如,如图11所示,同步信号块包括PSS和SSS,多个同步信号块中的PSS在时隙i内连续发送,SSS在时隙j内连续发送。两个时隙中对应位置的PSS和SSS属于同一个同步信号块。
PSS和SSS也可以分别在两个时隙内非连续发送,例如,如图12所示,多个同步信号块中的PSS在时隙i内非连续发送,SSS在时隙j内非连续发送。两个时隙中对应位置的PSS和SSS属于同一个同步信号块。
上述图11和图12中,同步信号块中的PSS和SSS在两个时隙内发送,这两种同步信号也可以在一个时隙内发送,其中,在一个时隙内发送的方式也有多种。
可选地,在本申请一个实施例中,可以将该多个同步信号块中的多个该第一同步信号和多个该第二同步信号在同一个时隙内交错发送。
例如,如图13所示,多个同步信号块中的PSS和SSS在时隙i内交错发送,相邻的PSS和SSS属于同一个同步信号块。
可选地,在本申请一个实施例中,可以将该多个同步信号块中的多个该第一同步信号在第三时隙内连续发送,将该多个同步信号块中的多个该第二同步信号在该第三时隙内连续发送。
也就是说,多个同步信号块中的多个第一同步信号和多个第二同步信号可以在同一个时隙内分别连续发送。
例如,如图14所示,多个同步信号块中的PSS在时隙i内连续发送,SSS也在时隙i内连续发送。对应位置的PSS和SSS属于同一个同步信号块。
上述图11-14中,PSS都能较集中的发送,这样,终端设备能够较短时间检测到PSS,从而能够缩短时频同步的时间。
以上各实施例中,同步信号块包括两种同步信号,根据系统需要,同步信号块还可以包括更多的同步信号。以下以第三同步信号为例进行说明,在同步信号块包括更多的同步信号的情况下,可以以此类推。
可选地,在本申请一个实施例中,可以将该多个同步信号块中的多个该第一同步信号、多个该第二同步信号和多个该第三同步信号在同一个时隙内交错发送。
例如,如图15所示,多个同步信号块中的PSS、SSS和TSS在时隙i内交错发送,相邻的PSS、SSS和TSS属于同一个同步信号块。
可选地,在本申请一个实施例中,可以将该多个同步信号块中每个同步信号块中的至少一种信号与其他信号在不相邻的符号上发送。
具体而言,本申请实施例可以与前述的将同步信号块中的信号分离发送的实施例相结合,即,在同步信号块包括多种同步信号时,可以将至少一种同步信号与其他同步信号在不相邻的符号上发送。也就是说,将至少一种同步信号与其他同步信号分离,这样可以 缩短该至少一种同步信号的搜索时间。
可选地,在本申请一个实施例中,可以将该多个同步信号块中每个同步信号块中的至少一种信号与其他信号在不同的时隙上发送。
具体而言,在本实施例中,将同步信号块中的多种同步信号分离到不同的时隙上发送,即,一部分同步信号在一个时隙上发送,另一部分同步信号在另一个时隙上发送。
可选地,在本申请一个实施例中,可以将该多个同步信号块中的多个该第一同步信号在第四时隙内连续或非连续发送,将该多个同步信号块中的多个该第二同步信号和多个该第三同步信号在第五时隙内交错发送。
也就是说,可以将一种同步信号在一个时隙内发送,其它同步信号在另一个时隙内发送。
例如,如图16所示,同步信号块包括PSS、SSS和TSS,多个同步信号块中的SSS和TSS在时隙i内交错发送,PSS在时隙j内非连续发送。
在图16中,将PSS单独在一个时隙内发送,也可以将其他同步信号单独在一个时隙内发送。
可选地,在本申请一个实施例中,可以将该多个同步信号块中的多个该第一同步信号和多个该第二同步信号在第六时隙内交错发送,将该多个同步信号块中的多个该第三同步信号在第七时隙内连续或非连续发送。
例如,如图17所示,多个同步信号块中的PSS和SSS在时隙i内交错发送,TSS在时隙j内非连续发送。将TSS单独在一个时隙内发送,便于对TSS进行单独处理。
针对上述各种同步信号块的构造和传输方式,终端设备相应地进行信号接收,即,检测同步信号块中的信号,获取同步信号块中的信号,并进行后续的处理。终端设备的接收与网络设备的发送相对应,因此不再赘述。
应理解,本申请实施例中的具体的例子只是为了帮助本领域技术人员更好地理解本申请实施例,而非限制本申请实施例的范围。
应理解,在本申请的各种实施例中,上述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本申请实施例的实施过程构成任何限定。
上文中详细描述了根据本申请实施例的传输信号的方法,下面将描述根据本申请实施例的传输信号的装置。
图18是根据本申请一个实施例的传输信号的装置的示意图。该装置可以为网络设备。
应理解,该装置可以对应于各方法实施例中的网络设备,可以具有方法中的网络设备的任意功能。
如图18所示,该装置包括处理器1810和收发器1820。
可选地,收发器1820可以称为远端射频单元(remote radio unit,RRU)、收发单元、收发机、或者收发电路等等。收发器1820可以包括至少一个天线和射频单元,收发器1820可以用于射频信号的收发以及射频信号与基带信号的转换。
可选地,该装置可以包括基带单元(baseband unit,BBU),该基带单元包括该处理器1810。该基带单元可以用于进行基带处理,如信道编码,复用,调制,扩频等,以及 对网络设备进行控制。该收发器1820与该基带单元可以是物理上设置在一起,也可以物理上分离设置的,即分布式网络设备。
在一个示例中,基带单元可以由一个或多个单板构成,多个单板可以共同支持单一接入制式的无线接入网,也可以分别支持不同接入制式的无线接入网。基带单元包括处理器1810。处理器1810可以用于控制网络设备执行前述各方法实施例中的相应操作。可选地,基带单元还可以包括存储器,用以存储必要的指令和数据。
