具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
本申请实施例可应用于各种类型的通信系统。图1为本申请实施例提供的一种应用场景示意图。如图1所示的通信系统，主要包括网络设备11和终端设备12。
其中，1)网络设备11可以是网络侧设备，例如，无线局域网(Wireless Local Area Network，WLAN)的接入点(Access Point,AP)、4G的演进型基站(Evolved Node B，eNB或eNodeB)、下一代通信的基站，如5G的新无线接入技术(New Radio Access Technology，NR)基站(next generation Node B，gNB)或小站、微站，还可以是中继站、发送和接收点 (Transmission and Reception Point，TRP)、路边单元(Road Side Unit,RSU)等。为了区别起见，将4G通信系统的基站称为长期演进(Long Term Evolution，LTE)eNB，5G通信系统的基站称为NR gNB，其中，一些基站既可以支持4G通信系统又可以支持5G通信系统,另外，基站的这些名称仅为了方便区别，并不具有限制意义。
2)终端设备12又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备、具有车与车(vehicle to vehicle，V2V)通信能力的车辆等。常见的终端设备例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
3)“多个”是指两个或两个以上，其它量词与之类似。“和/或”，描述关联对象的对应关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
需要说明的是，图1所示的通信系统中所包含的终端设备12的数量和类型仅仅是一种举例，本申请实施例并不限制于此。例如，还可以包括更多的与网络设备11进行通信的终端设备12，为简明描述，不在附图中一一描述。此外，在如图1所示的通信系统中，尽管示出了网络设备11和终端设备12，但是该通信系统可以并不限于包括网络设备11和终端设备12，例如还可以包括核心网节点或用于承载虚拟化网络功能的设备等，这些对于本领域技术人员而言是显而易见的，在此不一一赘述。
另外，本申请实施例不仅可应用于4G无线通信系统、车对外界(vehicle to everything，V2X)通信系统、设备到设备(Device-to-Device,D2D)通信系统、LTE的后续演化等通信系统，还可应用于下一代无线通信系统，以及还可应用于未来可能出现的其他系统,例如下一代的wifi网络、5G车联网等。其中，下一代无线通信系统可由多种制式的异构网络例如LTE、5G、卫星网络等相互融合而成，从而构成全球无缝覆盖的海、陆、空、天一体化的通信网络。在下一代无线通信系统中，网络设备通常配置有大规模天线阵列，该大规模天线阵列可形成多个波束，为不同的用户提供通信服务。其中，该网络设备可以是卫星，也可以是地面基站。如图2所示是以地面基站为例的大规模波束通信系统的示意图。如图2所示，21表示该大规模波束通信系统中的任意一个小区，以小区21为例，图2示出了小区21内终端发送上行数据的状态和基站22发送下行数据的状态。其中，基站22可配置有一个或多个天线阵列，从而形成多个波束，不同方向的波束可以覆盖到小区中不同位置的终端设备。可以理解的是，在卫星通信系统中，卫星可形成更多的波束，例如，单星可形成1000多个波束。
在终端设备进行初始接入时，终端设备和网络设备需要进行波束扫描，使得终端设备在某一个波束方向上接收到的网络设备的信号质量最好。如图3所示，网络设备31的天线阵列形成8个波束，终端设备32的天线阵列也形成8个波束。终端设备32需要从该8个波束中确定出一个波束，使得该终端设备32在该波束上接收到的网络设备31的信号质量最好。常用的波束扫描方法包括穷搜法和层次搜索法。下面对这两种方法分别进行介绍。
在穷搜法中，网络设备31可以分时的在其8个波束上发送SSB，SSB包括同步信号和广播信息，该同步信号具体包括主同步信号和辅同步信号。该广播信息具体可包括主信息块(Master Information Block，MIB)。MIB可包括SSB的标识信息，例如SSB号。另 外，SSB可用于标识波束，例如，SSB号和波束号(index)之间是一一对应的，不同的波束号对应不同的波束。具体的，网络设备31在不同的波束上分时发送标识信息不同的SSB。如图4所示，网络设备31可以在t1时刻在波束41上发送SSB1，在t2时刻在波束42上发送SSB2，在t3时刻在波束43上发送SSB3，以此类推。此外，网络设备31在其8个波束上分时发送SSB可以是周期性的，例如，当网络设备31在波束48上发送SSB8之后，可以继续在波束41上发送SSB1，以此类推。此处，可以将网络设备31在其8个波束上分时发送一遍相应的SSB的时长记为一个周期T。其中，在同一个周期T内，t1时刻到t8时刻中相邻时刻之间时间间隔可以相同，也可以不同。
在一个周期内，终端设备32可以在其8个波束中选择一个波束，例如，波束51，并在该波束51的方向上监听网络设备在该周期内发送的SSB。若网络设备31在波束44上发送SSB4时，终端设备32在波束51的方向上接收到的信号质量最好，则波束44和波束51是一对最优的波束对。进一步，终端设备根据波束44和波束51进行初始接入。若网络设备31在其8个波束上分时发送一遍相应的SSB之后，终端设备32在波束51的方向上未能接收到信号，或者接收到的信号的质量较差，则终端设备32可以再选一个波束，继续在该波束上监听网络设备发送的SSB，直到能够找到一个波束，使得该终端设备32在该波束上接收到的网络设备31的信号质量最好。可以理解的是，穷搜法的复杂度较高，并且终端设备的初始接入时延较大。
在层次搜索法中，网络设备31和终端设备32先在宽波束上进行波束扫描，并且在宽波束上对准之后，进一步在窄波束上进行扫描并对准。如图5所示，波束1和波束8可记为一级波束，波束2、波束3、波束9和波束10可记为二级波束，波束4、波束5、波束6、波束7、波束11、波束12、波束13、波束14可记为三级波束。其中，一级波束包括二级波束，例如，波束1包括波束2和波束3，波束8包括波束9和波束10。二级波束包括三级波束，例如，波束2包括波束4和波束5，波束3包括波束6和波束7，波束9包括波束11和波束12，波束10包括波束13和波束14。
网络设备31可在某一个一级波束、该一级波束包括的二级波束、以及该二级波束包括的三级波束上分时发送不同标识信息的SSB，例如，网络设备31可以在t1时刻在波束1上发送SSB1，在t2时刻在波束2上发送SSB2，在t3时刻在波束3上发送SSB3，以此类推，在t7时刻在波束7上发送SSB7。另外，网络设备31还可以在波束8、波束8包括的波束9和波束10、以及波束9和波束10分别包括的三级波束上分时发送不同标识信息的SSB，具体如图6所示。此外，网络设备31在t14时刻在波束14上发送SSB14之后，网络设备31还可以继续在波束1上发送SSB1、以及在波束1包括的窄波束上发送相应的SSB。此处，可以将网络设备31在一个一级波束、以及该一级波束包括的二级波束和三级波束上分时发送一遍相应的SSB的时长记为一个周期T。
终端设备32可以先确定其一级波束例如波束52和波束53中的哪个波束可以接收到网络设备31发送的信号。若波束53的方向上可以接收到网络设备31在波束1上发送的信号，则波束53和波束1是一对最优的波束对。
进一步，终端设备32再确定波束53包括的二级波束54和波束55中的哪一个可以接收到网络设备31发送的信号。若波束54的方向上可以接收到网络设备31在波束3上发送的信号，则波束3和波束54是一对最优的波束对。
进一步，终端设备32再确定波束54包括的三级波束56和波束57中的哪一个可以接收到网络设备31发送的信号。若波束56的方向上可以接收到网络设备31在波束6上发送的信号，则波束6和波束56是一对最优的波束对。进一步，终端设备根据波束6和波束56进行初始接入。可以理解的是，层次搜索法的复杂度较低，并且终端设备的初始接入时延较小。
但是在穷搜法和层次搜索法中，网络设备在不同波束上分时发送的SSB，除了SSB的标识信息不同之外，SSB中包括的其他信息是相同的，例如图5所示的波束1包括波束2和波束3，也就是说，波束1和波束2耦合，波束1和波束3耦合。因此，SSB1、SSB2、SSB3携带的同步信号是相同的。另外，SSB1、SSB2、SSB3携带的MIB除了SSB的标识信息不同之外，其他信息都是相同的。也就是说，SSB1、SSB2、SSB3中携带的同步信号和MIB会产生一定的冗余，导致网络设备分时发送的SSB所需的资源开销较大，造成资源浪费的问题。为了解决该问题，本申请实施例提出了一种信息传输方法，该方法可适用于如上所述的层次搜索法。下面结合实施例对该信息传输方法进行详细的描述。
图7为本申请实施例提供的一种信息传输方法流程图。该方法可以适用于如图8所示的通信系统。如图7所示，本实施例所述的信息传输方法包括如下步骤：
S701、接收装置接收发送装置在第一波束上发送的同步信号和小区专用信息，所述小区专用信息包括指示信息，所述指示信息用于指示是否存在波束专用信息。
在本实施例中，接收装置具体可以是终端设备，也可以为芯片。发送装置具体可以是网络设备，该网络设备可以是卫星，也可以是地面基站。第一波束为宽波束，第二波束为窄波束，其中，第一波束包括多个第二波束。
例如，该接收装置为如图8所示的终端设备，该发送装置为如图8所示的网络设备。该网络设备例如可以是卫星，卫星的一个波束或多个波束的覆盖范围可以是一个小区。该网络设备不仅可以给小区中的终端设备提供通信服务，还与核心网设备通信连接。
如图9所示，网络设备和终端设备的波束可划分为两级波束，例如，波束1、波束8、波束52、波束53是一级波束，波束2、波束3、波束9、波束10、波束54和波束55是二级波束。一级波束是宽波束，二级波束是窄波束，宽波束可记为第一波束，窄波束可记为第二波束。一个宽波束包括多个窄波束。
该网络设备可以在第一波束，例如波束1上发送同步信号和小区专用信息。其中，本申请实施例并不限定第一波束的时频资源。该同步信号包括主同步信号和辅同步信号。该小区专用信息具体可以是广播信息(Broadcast Information，BI)。该小区专用信息的功能和如上所述的SSB的功能相同，该小区专用信息的信令结构可以和MIB的信令结构相同，但不限于MIB的信令结构，还可以是其他的信令结构。在本申请实施例中，该小区专用信息包括指示信息，该指示信息用于指示是否存在波束专用信息。例如，该小区专用信息内新增一个比特位，当该比特位的取值为1时，表示存在波束专用信息。当该比特位的取值为0时，表示不存在波束专用信息。
S702、若所述指示信息指示存在波束专用信息，则所述接收装置接收所述发送装置在第二波束上发送的所述第二波束的波束专用信息。
若该小区专用信息中的指示信息指示存在波束专用信息，则如图9所示，该网络设备在第二波束，例如波束1包括的波束2和波束3上分时发送波束专用信息，其中，该网络 设备在波束2上发送的波束专用信息是波束2的波束专用信息，该网络设备在波束3上发送的波束专用信息是波束3的波束专用信息。本申请实施例并不限定第二波束的时频资源。
其中，波束专用信息具体也可以是广播信息，为了将小区专用信息和波束专用信息进行区分，可以将小区专用信息记为BI-0，将波束专用信息记为BI-1。小区专用信息是网络设备在小区级别广播的信息，波束专用信息是网络设备在波束级别广播的信息。也就是说，小区内的终端设备可以接收到该小区专用信息。波束专用信息是波束覆盖范围内的终端设备可以接收到的。如图9所示，假设波束1和波束8的覆盖范围是一个小区，则该网络设备可以在波束1和波束8上分时广播小区专用信息，使得小区内的每个终端设备可以接收到该小区专用信息。当网络设备在波束2上广播波束2的波束专用信息时，波束2覆盖范围内的终端设备可以接收到该波束2的波束专用信息。
另外，网络设备可以周期性广播小区专用信息BI-0，若该BI-0中的指示信息指示存在波束专用信息，则网络设备在宽波束广播小区专用信息BI-0后，继续在该宽波束包括的任意一个窄波束上广播该窄波束的波束专用信息BI-1，此处的逻辑如图10所示。如图9所示，网络设备在t1时刻在波束1上广播同步信号和小区专用信息BI-0，该BI-0中的指示信息指示存在波束专用信息，进一步，网络设备在t2时刻在波束2上广播波束2的波束专用信息BI-1，在t3时刻在波束3上广播波束3的波束专用信息BI-1。t3时刻之后，该网络设备可以继续在波束8上发送同步信号和小区专用信息、以及在波束8包括的二级波束上分时发送波束专用信息。其中，网络设备在一个一级波束、以及该一级波束包括的二级波束分时发送一遍相应的SSB的时长记为一个周期T。
S703、接收装置进行初始接入。
例如，终端设备在波束3的覆盖范围内，终端设备可周期性接收小区专用信息BI-0，并根据该BI-0中的指示信息，确定是否存在波束专用信息，若该指示信息指示存在波束专用信息，则终端设备继续接收波束专用信息BI-1，此处的逻辑如图11所示。例如，终端设备可先确定其一级波束，例如波束52和波束53中的哪个波束可以接收到同步信号和小区专用信息，或者波束52和波束53中的哪个波束上接收到的信号质量最好。若波束53的方向上可以接收到同步信号和小区专用信息，或者波束53的方向上接收到的信号质量最好，则该终端设备进一步确定二级波束，例如波束54和波束55中的哪个波束可以接收到波束3的波束专用信息，或者波束54和波束55中的哪个波束上接收到的信号质量最好。若波束54的方向上可以接收到波束3的波束专用信息，或者，波束54的方向上接收到的信号质量最好，则该终端设备可通过波束54和波束3进行初始接入。
本实施例通过发送装置在第一波束上发送同步信号和小区专用信息，当该小区专用信息包括的指示信息指示存在波束专用信息时，发送装置在该第一波束包括的任意一个第二波束上发送该第二波束的波束专用信息，由于该波束专用信息不包括同步信息和MIB，并且波束专用信息可以标识第二波束，使得发送装置在第一波束以及该第一波束包括的多个第二波束上分时发送的信息的冗余度大大减小，从而减小了发送装置广播信令的资源开销。
在上述实施例的基础上，网络设备和终端设备的波束还可以划分为三级波束，如图12所示，波束1和波束8可记为一级波束，波束2、波束3、波束9和波束10可记为二级波束，波束4、波束5、波束6、波束7、波束11、波束12、波束13、波束14可记为三级波束。其中，一级波束可记为第一波束，二级波束和三级波束可记为第二波束。网络 设备可以在t1时刻在波束1上发送同步信号和BI-0，在波束1包括的二级波束和三级波束上分时发送BI-1。另外，该网络设备还可以在波束1包括的三级波束上发送完相应的BI-1之后，在t8时刻在波束8上发送同步信号和BI-0，并在波束8包括的二级波束和三级波束上分时发送BI-1。
在第一阶段，网络设备和终端设备基于一级波束进行初步的波束对准，例如，波束1和波束53对准。终端设备解调出网络设备在一级波束上发送的同步信号和小区专用信息，并根据该小区专用信息包括的指示信息，确定是否存在波束专用信息，若存在波束专用信息，则在第二阶段，网络设备和终端设备基于二级波束进行较为精准的波束对准，例如，波束3和波束54对准。在第三阶段，网络设备和终端设备基于三级波束进行更为精准的波束对准，例如，波束6和波束56对准。
在本申请实施例中，波束专用信息BI-1具体可包括波束的空间标识(Beam-space-index)、频率标识(Beam-freq-index)、时间标识(Beam-time-index)、波束特征标识(Beam-characteristic)、解调参考信号位置标识(PDSCH DMRS position)、校验信息(Cyclic Redundancy Check，CRC)中的至少一个。其中，波束特征标识用于标识波束的形状、张角、定时提前、极化方式、波束级别中的至少一个，其中，波束级别用于指示该波束为第几层次的波束。其中，空间标识可以占N1个比特，时间标识可以占N2个比特，频率标识可以占N3个比特，波束特征标识可以占M个比特，解调参考信号位置标识可以占1个比特，校验信息可占K个比特。
具体的，网络设备在哪个第二波束上广播BI-1，则该BI-1具体可包括该第二波束的空间标识、频率标识、时间标识、波束特征标识、解调参考信号位置标识、校验信息中的至少一个。其中，该波束特征标识用于标识该第二波束的形状、张角、定时提前、极化方式、波束级别中的至少一个。其中，波束级别用于指示该波束为第几层次或几级的波束，从而适配多层次(例如层次大于或等于2)时的波束扫描。例如，波束2是二级波束，网络设备在波束2上发送的BI-1具体可包括波束2的空间标识、频率标识、时间标识、波束特征标识、解调参考信号位置标识、校验信息中的至少一个。其中，该波束特征标识用于标识波束2的形状、张角、定时提前、极化方式、波束级别(例如二级波束)中的至少一个。在上述实施例的基础上，不同的波束可以工作在相同的频点，如图13所示，4个不同的波束工作在相同的频点。在这种情况下，可以用波束的时间标识(Beam-time-index)对波束进行区分。
但是在一些场景中，例如，在卫星通信系统中，不同的波束也可以工作在不同的频点，如图14所示，在这种情况下，单靠波束的时间标识(Beam-time-index)可能无法对波束进行区分，此时，可以根据波束的时间标识(Beam-time-index)和频率标识(Beam-freq-index)对波束进行区分，例如，波束号＝f(时间标识,频率标识)，f为时间标识和频率标识的函数，此处并不限定f的形式。
在另一些场景中，同时、同频可能会存在不同空间的波束，此时，可以根据波束专用信息中的时间标识(Beam-time-index)和空间标识(Beam-space-index)标识不同的波束。例如，波束号＝f(时间标识,空间标识)，f为时间标识和空间标识的函数，此处并不限定f的形式。例如，波束号＝M*Beam-time-index+Beam-space-index，或者波束号＝Beam-time-index+N*Beam-space-index，再或者波束号＝[Beam-space-index, Beam-time-index]即Beam-space-index为高位，Beam-time-index为低位。
在其他一些场景中，还可以根据波束专用信息中的时间标识(Beam-time-index)、频率标识(Beam-freq-index)和空间标识(Beam-space-index)标识不同的波束。如图15所示，同时、同频存在两个不同空间波束，例如波束2和波束5。此时，波束号＝f(时间标识,空间标识，频率标识)，f为时间标识、空间标识和频率标识的函数。
可以理解的是，小区专用信息中也可包括第一波束的时间标识(Beam-time-index)、频率标识(Beam-freq-index)和空间标识(Beam-space-index)标识中的至少一个，并且该第一波束的波束号可以根据该第一波束的时间标识、频率标识和空间标识中的至少一个来确定。或者，小区专用信息中可以包括该第一波束的波束号。同理，波束专用信息中可以包括第二波束的波束号。
本实施例通过波束的空间标识和频率标识中的至少一个，以及波束的时间标识确定该波束的波束号，从而可以对同时、同频、不同空间存在的多个波束进行区分，实现了下一代更大规模波束通信系统的波束标识方法，提高了对波束的识别精度。
另外，可以理解的是，在上述实施例中，如果小区专用信息BI-0复用NR系统中的MIB格式，则当小区专用信息BI-0中的指示信息指示不存在波束专用信息时，网络设备在宽波束上广播的同步信号和该BI-0相当于NR系统中的SSB。从而使得本申请提供的信息传输方法可以兼容NR协议中的SSB配置方法，如图16所示。
对于终端设备而言，根据波束的空间标识(Beam-space-index)还可以进一步减少波束对准的时延，具体的，波束的空间标识和波束的空间位置一一对应。其中，波束的空间位置可以包括波束相对于网络设备的角度和/或波束中心点的位置信息。当终端设备接收到第二波束的波束专用信息，并且该波束专用信息包括该第二波束的空间标识时，该终端设备可根据该第二波束的空间标识确定该第二波束的空间位置，进一步，根据该第二波束的空间位置和该终端设备的位置信息，调整该终端设备的波束方向，使得该终端设备的波束与该网络设备的第二波束对准。其中，该终端设备的位置信息可以是该终端设备中的定位模块对该终端设备的定位信息。
例如图10所示，网络设备在波束3上广播的波束3的波束专用信息，该波束专用信息包括波束3的空间标识。当终端设备接收到网络设备在波束3上广播的波束3的波束专用信息时，终端设备可从该波束专用信息中解调出波束3的空间标识，并根据波束3的空间标识确定波束3的空间位置。进一步，该终端设备根据该波束3的空间位置和该终端设备的位置信息，调整波束54的方向，使得波束3和波束54对准，如此不仅可以减少终端设备波束对准的时延，同时还可以提高波束对准的准确性。
如图17所示，波束171、波束172和波束173是网络设备的波束，其中，波束171的空间标识＝1，波束172的空间标识＝2，波束173的空间标识＝3。其中，波束的空间标识和波束的空间位置一一对应。终端设备位于波束172的覆盖范围内。终端设备在波束172的覆盖范围内进行初始接入后，若该终端设备需要进行波束切换，则该终端设备可根据该终端设备当前所处的波束的空间标识，例如2，确定当前所处的波束的空间位置。具体的，终端设备可根据两个波束的空间标识来确定这两个波束是否在空间中相临近。例如，空间标识相邻的两个波束在空间中相临近。当终端设备确定该终端设备当前所处的波束的空间标识＝2时，该终端设备可确定空间标识＝1的波束和空间标识＝3的波束是其当前所处的波 束的相邻波束。进一步，根据该终端设备当前所处的波束的空间位置，对该波束的相邻波束进行测量，即该终端设备只需对空间标识＝1和空间标识＝3的波束进行测量，从而减小了终端设备在波束切换时的测量开销，节省了终端设备的能量消耗。
可以理解的是，上述实施例中的部分或全部步骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照上述实施例呈现的不同的顺序来执行，并且有可能并非要执行上述实施例中的全部操作。
