Description

一种波束同步的方法及装置 技术领域
本发明涉及通信技术领域，尤其涉及一种波束同步的方法及装置。
背景技术
未来第五代(the 5th Generation，简称5G)网络技术的发展是多种无线接入技术(radio access technology，简称RAT)的共同组网。为了实现5G的快速部署，5G发展的第一阶段可能是以长期演进(Long term evolution，简称LTE)为主RAT，5G技术为lean RAT(瘦RAT)的方式。控制面数据仅通过LTE技术发送，用户面数据通过5G技术发送，并且可以和LTE进行联合调度。相对LTE技术而言，5G技术工作频段较高，并且有着不同的波形，基于数据传输的多址方式和时延等要求，而且数据传输过程中信号质量也有所不同。
未来5G的一种多RAT共同组网方式下的网络构架如图1所示，一个LTERAT的基站覆盖范围内可以有多个5G RAT的小站。小站可以用于提高数据传输的可靠性，小站与终端(user equipment，简称UE)的通信采用5G技术。
5G系统中的的每个基站(包括5G RAT的小站)的覆盖范围内都会有多个波束(beam)，UE需要和接入的基站之间实现波束同步之后才可以进行数据的发送和接收。
现有技术中实现UE和基站的波束同步的方式为：UE在一段时间内进行波束搜索，波束具体搜索过程是UE对各个波束上接收的同步信号进行相干操作的过程。现有技术中，基站在不同的无线帧通过基站的各波束依次发送同步信号，UE需要尝试在各个时间上接收该同步信号并进行相干操作直至和其中一个波束同步上。假如该基站下有16个波束依次在不同的无线帧发送同步 信号(例如：第一个无线帧发第一个波束的同步信号，第二个无线帧发第二个波束的同步信号，其他同步信号的发送以此类推)，而UE处于第16个波束中，而此时基站刚好在第一个波束上发送信号，那么UE需要依次分别和每一个波束进行相干操作，直至确定自身需要同步的波束。
所以当波束数量较多时，上述波束搜索的方式会导致搜索过程耗时多，导致同步时延增加。
发明内容
本发明提供一种波束同步的方法及装置，本发明所提供的方法和装置解决现有波束同步方式耗时多的问题。
第一方面，提供一种波束同步的方法，应用于终端侧，包括：
终端UE接收包括至少一个波束的基站通过每个波束波束发送的同步信号；其中，该同步信号包含用于区分发送所述同步信号的波束的区别信息；
从接收到的至少一个同步信号中确定信号最强的第一同步信号；
确定所述第一同步信号对应的第一区别信息，根据预设的区别信息与波束的对应关系确定所述第一区别信息对应的波束为所述UE同步的波束。
通过实施第一方面描述的方法，终端可以利用码分，时分，频分接收同步信号，然后在利用每个编码、时刻以及频域资源与波束的对应关系确定UE同步的波束，从而能够有效的缩短UE同步的时长，起到减小同步时延的效果。
第二方面，提供了一种波束同步的方法，应用于基站侧，包括：
包括至少一个波束的基站通过每个波束波束发送同步信号；其中，该同步信号包含用于区分发送所述同步信号的波束的区别信息；使得接收到所述同步信号的终端根据第一同步信号对应的第一区别信息和预设的区别信息与波束的对应关系确定UE同步的波束；所述第一同步信号为所述同步信号中信 号最强的信号。
通过实施第二方面描述的方法，在实现UE的波束同步时，基站利用码分、时分和频分的方式对每个自身的波束在同步信息中标示，而且该同步信息是每个波束对应一个与自身唯一对应的同步信息，所以基站一次性在不同波束上发送同步信号后，终端则可以根据接收到的同步信息确定自身同步的波束。
因为终端侧是对同步信息进行解析得到同步信号以及需要同步的波束，基站侧是采用不同的方式发送同步信号从而让终端确定需要同步的波束，所以基站和终端侧的实现是两个相对应的过程，以下对终端侧的接收和同步信号解析过程进行说明，具体基站侧的发送过程则不再赘述：
基于上述第一方面和第二方面，在一种实现方式中，确定所述第一同步信号对应的第一区别信息，根据预设的区别信息与波束的对应关系确定所述第一区别信息对应的波束为所述UE同步的波束的实现方式可以有多种，具体包括：
第一种方式：当所述区别信息为所述同步信号中携带的波束标识序列；其中，波束与所述波束标识序列一一对应；则从所述第一同步信号中获取第一波束标识序列，并根据预设的波束与波束标识序列的对应关系确定所述第一波束标识序列对应的波束为所述UE同步的波束。
在这种实现方式中，波束标识序列可以同时标示波束和基站两者的信息，该方法还包括：
从预存的波束标识序列与预设编号的对应关系中，确定与所述第一波束标识序列对应的第一编号；其中，每个基站所包括的多个波束分别对应所述预设编号中的不同区段；
确定所述第一编号对应的基站为所述同步的波束对应的基站。
在该实现方式中，将基站的波束统一编号，通过该方式可以在确定波束 后直接通过统一编号的编号原则，则可以直接确定终端同步的波束以及波束对应的基站。所以发送一次同步信号达到确定两个信息的效果，有效的节约资源。
第二种方式：当所述区别信息为基站发送所述同步信号的时刻；其中，波束与基站发送所述同步信号的时刻一一对应；则确定接收所述第一同步信号的第一时刻，并根据预设的波束与时刻的对应关系确定所述第一时刻对应的波束为所述UE同步的波束；
现有技术的方案中，必须一个无线帧发送一个波束的同步信号，如果基站包括多个波束，每个波束对应一个无线帧，对于某一个UE可能需要经过好几个无线帧的时延后才能确定需要同步的波束；而在上述第二方式中基站发送同步信号时是在同一个无线帧、同一个无线帧中的一个子帧或一个符号内所以在时延上相比现有技术有了很大的缩短。
第三种方式：当所述区别信息为接收所述同步信号的频域资源；其中，每一个波束对应一个频域资源；则确定接收所述第一同步信号的第一频域资源，并根据预设的波束与频域资源的对应关系确定所述第一频域资源对应的波束为所述UE同步的波束；
通过这种方式基站可以同时通过多个频域资源一次性将所有波束的同步信号发送给终端，终端通过接收到同步信号的频域去确定需要同步的波束，能够有效的缩短波束同步的时延。
终端在进行同步的时候除了与波束同步以外还需要确定同步的波束对应的基站，所以基于上述波束同步的方式终端确定基站的方式也可以采用频分、码分和时分三种方式，而且确定基站的方式和波束同步方式可以自由组合，只是在波束同步选择某一种具体的实现方式后，如果确定基站的方式与波束同步采用不同的方式，则可以将基站的信息与波束同步信息一起发送给UE； 但是如果波束和基站选择同样的方式进行，则需要发送两次同步信号，其中包括用于波束同步的同步信号和用于确定基站的同步信号；基于上述原理，终端解析同步信号的方式可以是(因为波束同步和确定波束对应基站分别都可以采用三种方式，所以以下对三种方式进行自由组合的具体说明)：
在一种实现方式中，当所述区别信息为所述同步信号中携带的波束标识序列，该方法还包括：

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例所提供的方法应用与基站与终端(UE)进行同步的通信系统中，其中，基站与UE通过某种空口技术相互通信。所述空口技术可包括：现有的2G(如GSM)、3G(如UMTS、WCDMA、TD-SCDMA)、4G(如FDD LTE、TDD LTE)以及未来即将面市的4.5G、5G系统等。基站可包括：LTE通信系统中的eNB、UMTS通信系统中的NodeB和GSM通信系统中的BS(Base Station)。UE即是3G和4G网络中的用户终端，相当于2G网络中的移动台(Mobile Station，MS)，可包括：手机、平板电脑(携带SIM卡)等无线终端，也可以是机器对机器(M2M，Machine to Machine)通信中的无线终端(例如传感器，能远程抄表的仪表)，以及其他移动通信设备。
本发明实施例提供的方案适用于通过多个波束覆盖的网络系统中，终端需要确定同步的波束和基站时，可以利用码分、频分或者时分的方式发送同步信息给终端，从而使得终端根据码分、频分或者时分方式解析到同步信息后，根据该同步信息确定终端需要同步波束和基站，从而减小终端进行波束和基站同步的时延。
下面结合说明书附图对本发明实施例作进一步详细描述。
如图2所示，本发明实施例提供一种波束同步的方法，具体实现包括：
步骤201，UE接收包括至少一个波束的基站通过每个波束(beam)发送的同步信号；其中，该同步信号包含用于区分发送所述同步信号的波束的 区别信息。
步骤202，所述UE从接收到的至少一个同步信号中确定信号最强的第一同步信号。
本发明实施例对UE确定信号最强的第一同步信号的方式不做特别限定，例如可以采用以下两种方式中的任意一种：
a，UE确定每个同步信号的信噪比，将信噪比最高的同步信号为信号最强的第一同步信号；
b，UE将接收到的同步信号与预存的信号进行相干处理，与预存信号相干性最大的同步信号为第一同步信号。
步骤203，确定所述第一同步信号对应的第一区别信息，根据预设的区别信息与波束的对应关系确定所述第一区别信息对应的波束为所述UE同步的波束。
具体实现实例中，终端可以通过时分、码分和频分的方式确定需要同步的波束，则确定所述第一同步信号对应的第一区别信息，根据预设的区别信息与波束的对应关系确定所述第一区别信息对应的波束为所述UE同步的波束的实现方式为以下方式中的任意一种，具体包括：
A，当所述区别信息为接收所述同步信号的频域资源；其中，每一个波束对应一个频域资源；则确定接收所述第一同步信号的第一频域资源，并根据预设的波束与频域资源的对应关系确定所述第一频域资源对应的波束为所述UE同步的波束；或者
B，当所述区别信息为基站发送所述同步信号的时刻；其中，波束与基站发送所述同步信号的时刻一一对应；则确定接收所述第一同步信号的第一时刻，并根据预设的波束与时刻的对应关系确定所述第一时刻对应的波束为所述UE同步的波束；或者
在实施方式B中，当基站在一个无线帧、一个子帧或同一个符号的不同时刻发送所述同步信号时，每个同步信号所占用符号的长度与现有实现不相同，所以在该实施例中每个同步信号所占用的符号长度T’＝T/n，对应的子载波间隔f’＝f*n，快速傅里叶变换(Fast Fourier Transform，FFT)点数N’＝N/n，T为符号长度，f为子载波间隔，N为FFT点数。
C，当所述区别信息为所述同步信号中携带的波束标识序列；其中，波束与所述波束标识序列一一对应；则从所述第一同步信号中获取第一波束标识序列，并根据预设的波束与波束标识序列的对应关系确定所述第一波束标识序列对应的波束为所述UE同步的波束。
可选的，因为一个UE既会收到一个基站下多个波束发送的信号，也会收到别的基站发送的信号。所以在波束同步的过程中：需要确定波束以及该波束对应的基站，所以基于上述波束同步的方式终端确定基站的方式也可以采用频分、码分和时分三种方式，而且确定基站的方式和波束同步方式可以自由组合，只是在波束同步选择某一种具体的实现方式后，如果确定基站的方式与波束同步采用不同的方式，则可以将基站的信息与波束同步信息一起发送给UE；但是如果波束和基站选择同样的方式进行，则需要分别发送两次同步信号(包括用于波束同步的同步信号和用于确定基站的同步信号)，确定同步的波束对应基站的具体实现可以是：
方式一，当所述区别信息为所述同步信号中携带的波束标识序列，则对应的基站同步的方式可以是以下任意一种：
1a，一个波束标识序列同时包括基站同步信息和波束同步信息，具体实现可以是：
从预存的波束标识序列与预设编号的对应关系中，确定与所述第一波束标识序列对应的第一编号；其中，每个基站所包括的多个波束分别对应所述 预设编号中的不同区段；确定所述第一编号对应的基站为所述同步的波束对应的基站。
即将一定范围区域内基站所包括的波束都统一编号，例如：区域内总共有三个基站(基站a、基站b和基站c)每个基站包括四个波束，则对应的四个基站所包括的12个波束的编号可以是1～12，基站a的四个波束依次对应的编号是1～4，基站b的四个波束依次对应的编号是5～8，基站c的四个波束依次对应的编号是9～12。则对应的如果终端通过接收到的波束标识序列得到第一编号为5，则对应的可以确定终端同步的波束和同步波束对应的基站，确定的同步波束对应的基站为基站b，同步的波束为基站b的第一个波束。
1b，单独发送基站同步信号，具体实现可以是：
终端UE接收基站发送的基站同步信号；其中，该基站同步信号中包含用于区分发送该基站同步信号的基站的基站标识序列；
UE从接收到的所述基站同步信号中确定信号最强的第一基站同步信号；
UE确定所述第一基站同步信号中的第一基站标识序列，根据所述第一基站标识序列确定所述同步的波束对应的基站。
1c，确定同步的波束对应基站的方式和确定同步波束采用不同的方式，则一个同步信息可以包含两种区别信息，同步信号中携带的波束标识序列可以区分波束，另一种区别信息可以区分基站。具体实现可以是：
确定接收到所述第一同步信号的第二频域资源，其中，每一个基站对应一个频域资源；则根据预设的基站与频域资源的对应关系确定所述第二频域资源对应的基站为所述同步的波束对应的基站；或者
确定接收到所述第一同步信号的第二时刻，其中，基站与基站发送所述同步信号的时刻一一对应；根据预设的基站与时刻的对应关系确定所述第二时刻对应的基站为所述同步的波束对应的基站。
方式二，当所述区别信息为基站发送所述同步信号的时刻，该方法还包括：
2a，确定同步的波束对应基站的方式和确定同步波束采用不同的方式，则一个同步信息可以包含2种区别信息，接收同步信号时刻可以区分波束，另一种区别信息可以区分同步波束对应的基站，具体实现可以是：
确定接收到所述第一同步信号的第二频域资源，其中，每一个基站对应一个频域资源；则根据预设的基站与频域资源的对应关系确定所述第二频域资源对应的基站为所述同步的波束对应的基站；或者
从所述第一同步信号中获取第二基站标识序列；其中，基站与所述基站标识序列一一对应；并根据预设的基站与基站标识序列的对应关系确定所述第二基站标识序列对应的基站为所述同步的波束对应的基站。
2b，基站同步和波束同步采用相同的方式，具体实现可以是：
UE在一个无线帧、无线帧中的一个子帧或一个符号内的不同时刻接收基站发送的基站同步信号；其中，基站与基站发送同步信号的时刻一一对应；
本实施例中，发送同步信号的时间间隔与现有技术相比进行缩短处理，而且不管是在一个无线帧、一个无线帧中的一个子帧或者是一个符号中发送同步信号都是连续发送的。
UE从接收到的所述基站同步信号中确定信号最强的第二基站同步信号；
UE确定接收到所述第二基站同步信号的第三时刻，根据预设的基站发送同步信号的时刻与基站的对应关系确定所述第三时刻对应的基站为所述同步的波束对应的基站。
方式三，当所述区别信息为接收所述同步信号的频域资源，该方法还包括：
3a，确定同步的波束对应基站的方式和确定同步波束采用不同的方式， 则一个同步信息可以包含2种区别信息，接收同步信号的频域资源可以区分波束，另一种区别信息可以区分基站，具体实现可以是：
从所述第一同步信号中获取第三基站标识序列；其中，基站与所述基站标识序列一一对应；并根据预设的基站与基站标识序列的对应关系确定所述第三基站标识序列对应的基站为所述同步的波束对应的基站；或者
确定接收到所述第一同步信号的第四时刻，其中，基站与基站发送所述同步信号的时刻一一对应；根据预设的基站与基站发送所述同步信号的时刻的对应关系确定所述第四时刻对应的基站为所述同步的波束对应的基站。
3b，基站同步和波束同步采用相同的方式，具体实现可以是：
UE在不同频域资源接收基站发送的基站同步信号；其中，基站与基站发送基站同步信号的频域资源一一对应；
UE从接收到的所述基站同步信号中确定信号最强的第三基站同步信号；
UE确定接收到所述第三基站同步信号的第三频域资源，根据预设的基站与基站发送的基站同步信号的频域资源的对应关系确定所述第三频域资源对应的基站为所述同步的波束对应的基站。
实施例

包括至少一个波束的基站通过每个波束(beam)发送同步信号；其中，该同步信号包含用于区分发送所述同步信号的波束的区别信息；使得接收到所述同步信号的终端根据第一同步信号对应的第一区别信息和预设的区别信息与波束的对应关系确定UE同步的波束；所述第一同步信号为所述同步信号中信号最强的信号。
在具体实现实例中，基站可以通过时分、码分和频分的方式发送用于波束同步的同步信号，然后终端根据接收到同步信号的具体参数(该参数包括 时间、频域或标识信息)确定需要同步的波束，具体实现可以是以下方式中的任意一种：
A，当所述区别信息为发送所述同步信号的频域资源；其中，每一个波束对应一个频域资源；则基站通过不同频域资源发送所述同步信号；或者
B，当所述区别信息为发送所述同步信号的时刻；其中，波束与发送所述同步信号的时刻一一对应；则基站在一个无线帧、一个子帧或一个字符的不同时刻发送所述同步信号；或者
C，当所述区别信息为所述同步信号中携带的波束标识序列；其中，波束与所述波束标识序列一一对应；则基站在不同波束上发送携带不同波束标识序列的同步信号。
可选的，终端在进行同步的时候除了与波束同步以外还需要确定同步的波束对应的基站，所以基于上述波束同步的方式终端确定基站的方式也可以采用频分、码分和时分三种方式，而且基站同步和波束同步方式可以自由组合，只是在波束同步选择某一种具体的实现方式后，如果确定基站的方式选择与波束同步不同的方式，则可以将确定基站的信息与波束同步信息一起发送给UE；但是如果波束同步和确定基站选择同样的方式进行，则需要发送两次同步信号(包括用于波束同步的同步信号和用于确定基站的同步信号)，具体实现可以是：
方式一，波束同步的方式为波束标识序列，则区分的基站的方式可以是：
1a，一个标识序列同时包括基站同步信息和波束同步信息，具体实现可以是：
当所述区别信息为所述同步信号中携带的波束标识序列，其中，所述波束标识序列与预设编号的对应，且每个基站所包括的多个波束分别对应所述预设编号中的不同区段；使得所述终端根据所述第一同步信号对应的第一编 号确定所述同步的波束对应的基站。
1b，单独发送基站同步信号，具体实现可以是：

1c，基站同步和波束同步采用不同的方式，则同步信息可以包含2种区别信息，同步信号中携带的波束标识序列可以区分波束，另一种区别信息可以区分同步波束对应的基站。具体实现可以是：
基站在与自身对应的第一频域资源上发送所述同步信号，其中，基站与基站发送所述同步信号的频域资源一一对应；当所述终端在所述第一频域资源接收到所述同步信号，则根据预设的基站与基站发送所述同步信号的频域资源的对应关系确定所述基站为所述同步的波束对应的基站；或者

3a，基站同步和波束同步采用不同的方式，则同步信息可以包含2种区别信息，发送同步信号的频域资源可以区分波束，另一种区别信息可以区分同步波束对应的基站，具体实现可以是：
基站在所述同步信号中添加用于唯一标示自身的第三基站标识序列；其中，当终端接收到所述第三基站标识序列，则根据预设的基站与基站标识序列的对应关系确定所述第三基站标识序列对应的基站为所述同步的波束对应的基站；或者
