Description

一种发送SSB的方法和相关装置
本申请要求于2021年5月26日提交中国专利局、申请号为202110579119.9、发明名称为“一种发送SSB的方法和相关装置”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
本申请涉及通信技术领域，尤其涉及一种发送同步信号和广播物理信道PBCH块SSB的方法和相关装置。
背景技术
当前的通信系统中，用户设备搜索基站发送的同步信号块(synchronization signal and PBCH block，SSB)进行小区搜索、同步和测量，以接入网络。一般的，基站按照20毫秒的周期发送SSB。但是，在小区轻载、空载的场景中，广播SSB的消息占用过多信道资源(例如8％)。为此，基站也可以按照40/80/160毫秒的周期发送SSB，以降低基站消耗的信道资源。
但是，在独立组网(stand alone，SA)的场景中，用户设备需要采用SSB测量来辅助跟踪参考信号(tracking reference signal，TRS)测量，若基站拉长SSB的周期，可能会产生时偏异常，导致在网的用户设备掉话，或者新用户设备无法入网。

具体实施方式
本申请实施例提供了一种发送同步信号和广播物理信道PBCH块SSB的方法和相关装置，用于通过第一波束的不同的同步周期分别发送全量SSB或同步SSB。
下面结合附图，对本申请的实施例进行描述。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，这仅仅是描述本申请的实施例中对相同属性的对象在描述时所采用的区分方式。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，以便包含一系列单元的过程、方法、系统、产品或设备不必限于那些单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它单元。
本申请实施例的技术方案可以应用于各种数据处理的通信系统，例如码分多址(code division multiple access，CDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single carrier FDMA，SC-FDMA)和其它系统等。术语“系统”可以和“网络”相互替换。CDMA系统可以实现例如通用无线陆地接入(universal terrestrial radio access，UTRA)，CDMA2000等无线技术。UTRA可以包括宽带CDMA(wideband CDMA，WCDMA)技术和其它CDMA变形的技术。CDMA2000可以覆盖过渡标准(interim standard，IS)2000(IS-2000)，IS-95和IS-856标准。TDMA系统可以实现如全球移动通信系统(global system for mobile communication，GSM)等无线技术。OFDMA系统可以实现诸如演进通用无线陆地接入(evolved UTRA，E-UTRA)、 超级移动宽带(ultra mobile broadband，UMB)、IEEE 802.11(Wi-Fi)，IEEE 802.16(WiMAX)，IEEE 802.20，Flash OFDMA等无线技术。UTRA和E-UTRA是UMTS以及UMTS演进版本。3GPP在长期演进(long term evolution，LTE)和基于LTE演进的各种版本是使用E-UTRA的UMTS的新版本。第五代(5 Generation，5G)通信系统、新空口(New Radio，简称“NR”)是正在研究当中的下一代通信系统。此外，所述通信系统还可以适用于面向未来的通信技术，都适用本申请实施例提供的技术方案。本申请实施例描述的系统架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
请参阅图1-1所示，为本申请实施例提供的一种通信系统的组成结构示意图。本申请实施例提供一种通信系统100，包括基站110和用户设备120。
其中，用户设备120可以包括手机、平板电脑、PDA(Personal Digital Assistant，个人数字助理)、POS(Point of Sales，销售终端)、车载电脑等任意终端设备。
以手机为例，图1-2示出的是与本申请实施例提供的终端相关的手机的部分结构的框图。参考图1-2，手机包括：射频(Radio Frequency，RF)电路1110、存储器1120、输入单元1130、显示单元1140、传感器1150、音频电路1160、无线保真(wireless fidelity，WiFi)模块1170、处理器1180、以及电源1190等部件。本领域技术人员可以理解，图1-2中示出的手机结构并不构成对手机的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
在一些可行的实现方式中，基站110可以为5G无线接入网(NG-RAN)中的gNB。如图1-3所示，5G网络架构包括5G接入网(NG-RAN)和5G核心网(5GC)，其中，5G无线接入网包括两种节点：gNB和ng-eNB。
其中，gNB应用向用户设备120提供NR的用户面和控制面的协议终端的节点，并且经由NG接口连接到5GC。ng-eNB应用向用户设备120提供E-UTRA的用户面和控制面的协议终端的节点，并且经由NG接口连接到5GC。由此可知，gNB是独立组网需要用到的，而ng-eNB是为了向下兼容4G网络，为了不同核心网而设置的。
如上图1-3所示，本申请涉及的网元为gNB，gNB中的涉及到如图1-4所示，它们在整体5G网络的功能划分，具体的各功能的内容为现有技术，此处不做赘述。
当前的通信系统中，用户设备120搜索基站110发送的SSB进行小区搜索、同步和测量，以接入网络。一般的，基站110按照20毫秒的周期发送SSB。但是，在小区轻载、空载的场景中，广播SSB的消息占用过多信道资源(例如8％)。为此，基站110也可以按照40/80/160毫秒的周期发送SSB，以降低基站消耗的信道资源。例如，如图1-5所示，在小区轻载、空载的场景中，将原来20毫秒时长的SSB周期拉长到160毫秒。在独立组网(stand alone，SA)的场景中，用户设备120需要采用SSB测量来辅助跟踪参考信号(tracking reference signal，TRS)测量，若基站110拉长SSB的周期，可能会产生时偏异常，导致在网的用户设备120在第二个20毫秒的周期开始掉话，或者新用户设备120无法入网。
前述实施例介绍了本申请提供给的通信系统100，接下来通过实施例1和实施例2介 绍基于该通信系统100执行的通信方法。
实施例1、
请参阅图2-1所示，本申请实施例提供的一种发送SSB的方法主要包括如下步骤：
201、基站确定全量周期，全量周期包括N个同步周期，N为大于等于2的整数。
在本申请实施例中，基站可以设置全量周期，每个全量周期发送一次全量SSB。需要说明的是，一个全量周期包括N个同步周期，其中，每个同步周期为一个同步周期。在一些可行的实现方式中，同步周期的时长为20毫秒，全量周期的时长可以为40/80/160毫秒。
例如，若全量周期为40毫秒，同步周期为20毫秒，那么一个全量周期包括2个(40毫秒/20毫秒)同步周期；若全量周期为80毫秒，同步周期为20毫秒，那么一个全量周期包括4个(80毫秒/20毫秒)同步周期；若全量周期为160毫秒，同步周期为20毫秒，那么一个全量周期包括8个(160毫秒/20毫秒)同步周期。
示例性的，如图2-2所示，全量周期的时长为80毫秒，同步周期的时长为20毫秒，那么全量周期包括4个同步周期，分别为同步周期0/1/2/3。
202、基站确定第一同步周期，第一同步周期为N个同步周期中的一个，第一同步周期用于在第一波束发送全量SSB。
在本申请实施例中，当基站确定了全量周期后，基站可以从N个同步周期中确定与第一波束对应的第一同步周期，该第一同步周期用于通过第一波束发送全量SSB。例如，如图2-2所示，基站可以随机确定同步周期0，作为第一同步周期。在一些可行的实现方式中，基站还可以确定多于一个同步周期，作为第一同步周期。例如，基站确定同步周期0/1/2，或，同步周期0/1/3，或，同步周期0/2/3，或，同步周期1/2/3，或，同步周期0/1，或，同步周期0/2，或，同步周期0/3，或，同步周期1/2，或，同步周期1/3，或，同步周期2/3，作为第一同步周期。
203、基站确定第二同步周期，第二同步周期为N个同步周期中的一个，第二同步周期用于在第一波束发送同步SSB。
在一些可行的实现方式中，当基站确定了第一同步周期后，可以进一步确定第二同步周期，该第二同步周期用于通过第一波束发送同步SSB，其中第二同步周期为N个同步周期中不同于第一同步周期的同步周期。
例如，如图2-2所示，基站可以随机确定同步周期0，作为第一同步周期，那么基站可以进一步确定同步周期1/2/3中的任意1个作为第二同步周期。在一些可行的实现方式中，基站可以确定同步周期1/2/3中的两个分别作为2个同步周期，此处不做限定。在一些可行的实现方式中，基站可以确定同步周期1/2/3分别作为3个同步周期，此处不做限定。
204、基站在第一同步周期通过第一波束发送全量SSB。
在本申请实施例中，当基站确定了第一同步周期后，可以在第一同步周期发送全量SSB。
需要说明的是，如图2-3所示，全量SSB由主同步信号(primary Synchronization Signals，PSS)、辅同步信号(secondary synchronization signals，SSS)、广播物理 信道(physical broadcast channel，PBCH)三部分共同组成。全量SSB在时域上占用4个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，在频域占用240个子载波，编号为0～239。其中，PSS位于符号0的中间127个子载波，SSS位于符号2的中间127个子载波，为了保护PSS和SSS，两端分别有不同的子载波。另外，PBCH位于符号1/3，以及符号2，其中符号1/3上占0～239所有子载波，符号2上占用除去SSS占用子载波及保护SSS的子载波以外的所有子载波。
其中PSS、SSS、PBCH占用不同的符号和占用资源如图2-4所示：协议38.211 Table 7.4.3.1-1。其中，k和l分别表示SSB内的频域索引和时域索引，Set 0表示用户设备假定协议38.211 Table 7.4.3.1-1中的该部分的RE被设置为0。
需要说明的是，PBCH由于承载系统广播消息，用户设备不需要在每个同步周期都检索到，只需要在至少在一个同步周期中检索到即可。
需要说明的是，在第五代移动通信技术(5th generation mobile communication technology，5G)中引入了超大规模天线阵列，其中，毫米波频段天线个数可能高达256。波束赋型在5G的应用可以通过波束赋型使信号能量更加集中增强覆盖，减少用户间及小区间干扰。通过SSB波束扫描，基站和用户设备之间建立一个合适的波束方向对，进行随后的接入及数据传输以及同步。具体的，SSB波束扫描可以如图2-5所示，采用时分的方式在不同时间经由不同的波束发送。在SSB波束扫描的过程中，用户设备选择信号强度最大的波束作为初始波束方向，进行随后的处理。例如，如图2-6所示，用户设备1从波束3接收到的信号强度最大，而用户设备2从波束7接收到的信号强度最大。
当搜索到信号强度最大的波束后，用户设备会在与所选择的SSB的索引相关的时间发送物理随机接入信道(physical random access channel，PRACH)的接入信息。基站通过解析收到的PRACH的接入信息，可以判断终端所处方向并建立初始波束对。
205、基站在第二同步周期通过第一波束发送第一同步SSB。
在本申请实施例中，当基站确定了第二同步周期后，可以在第二同步周期发送同步SSB。具体的，如图2-7所示，基站在同步周期0上通过第一波束发送全量SSB，在同步周期1/2/3通过第一波束发送同步SSB，例如在同步周期1内发送第一同步SSB。需要说明的是，如图2-8所示，同步SSB相比全量SSB，同步SSB包括SSS和PSS，而不包括PBCH。
在一些可行的实现方式中，基站可以同时发送多个波束。为了避免在不同波束同时发送全量SSB，导致在该同步周期的占用过多资源，可以让不同波束上的全量SSB分别在全量周期中不同同步周期中发送。示例性的，可以通过实施例2实现。
实施例2、
请参阅图3-1所示，本申请实施例提供的一种发送SSB的方法，主要包括如下步骤：
301、基站确定全量周期，全量周期包括N个同步周期，N为大于等于2的整数。
请参考步骤201，此处不做赘述。
302、基站确定第一同步周期中发送全量SSB的第一波束，第一同步周期为N个同步周 期中的一个。
举例说明，设现有系统具有多个波束，例如4/8/16个波束，如图3-2所示，以4个波束为例，分别为波束0/1/2/3，基站确定在同步周期0中发送全量SSB的波束0。在一些可行的实现方式中，基站可以从4个波束中随机选择，在此，以选择波束0为例。在本申请实施例中，当基站确定了波束0为第一同步周期中发送全量SSB的第一波束后，为了避免在不同波束同时发送全量SSB，导致在该同步周期的占用过多资源，基站同时确定了波束1/2/3为第一同步周期中发送同步SSB的波束。
303、基站确定第二同步周期中发送全量SSB的第二波束。
在本申请实施例中，如图3-2所示，基站确定在同步周期0中发送全量SSB的波束0后，在第二同步周期中，基站可以从剩余的波束1/2/3中选择一个波束，作为同步周期1的第二波束。另外，为了避免在不同波束同时发送全量SSB，导致在该同步周期的占用过多资源，基站同时确定了波束2/3为第二同步周期中发送同步SSB的波束。同理，基站可以从剩余的波束2/3中选择一个波束，作为同步周期2的第三波束，最后剩余的波束3作为同步周期3的第四波束。
304、基站在第一同步周期通过第一波束发送全量SSB，并在第一同步周期通过第二波束发送第二同步SSB。
在本申请实施例中，当基站确定第一同步周期中发送全量SSB的第一波束后，即可在第一同步周期中通过第一波束发送全量SSB，并在第一同步周期通过第二波束发送第二同步SSB。例如，如图3-2所示，当基站在同步周期0中通过波束0发送全量SSB，为了避免在不同波束同时发送全量SSB，导致在该同步周期的占用过多资源，基站同时在同步周期0中通过波束1/2/3发送同步SSB(即第二同步SSB)。
305、基站在第二同步周期通过第一波束发送第一同步SSB，并在第二同步周期通过第二波束发送全量SSB。
在本申请实施例中，当基站确定了在第二同步周期中发送全量SSB的第二波束后，可以在第二同步周期中通过第二波束发送全量SSB。例如，如图3-2所示，基站在同步周期1上通过第二波束发送全量SSB，在同步周期0/2/3中通过波束0/2/3发送同步SSB。
需要说明的是，同步SSB相比全量SSB，同步SSB包括SSS和PSS，而不包括PBCH。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请并不受所描述的动作顺序的限制，因为依据本申请，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本申请所必须的。
