Description

一种信息传输方法、设备及计算机可读存储介质 技术领域
本发明实施例涉及移动通信技术领域，尤其涉及一种信息传输方法、设备及计算机可读存储介质。
背景技术
随着通信技术的发展，第五代移动通信技术(5G，5th Generation)的研究也已经展开。5G的无线接入叫New Radio，简称NR。
目前的NR系统的设计都是针对在授权频谱上独立部署(SA，StandAlone)场景的，在SA场景中，需要承载系统信息。但是，对于免授权频谱使用NR系统的情况，是可能存在独立部署场景和非独立部署(NSA，Non StandAlone)场景两种的。在NSA场景下，携带系统信息的系统消息是通过授权频谱发送，在免授权频谱的载波上，是不需要承载系统信息的。在这种情况下，由于免授权频谱是共享的，那么当同时存在NSA场景和SA场景在免授权频谱上都发送的同步信号块(SSB，Synchronization Signal Block)时，会导致属于NSA场景下发送的SSB，不会指示系统信息的相关信息，从而使得UE在基于该SSB进行频谱搜索实现5G的接入，是没有结果的，反而增加了UE的耗电和信息传输的复杂度，降低了UE的接入效率。
发明内容
为解决上述技术问题，本发明实施例期望提供一种信息传输方法、设备及计算机可读存储介质，能够在5G NR系统中，节省UE的电量，简化信息传输交互，从而提高了UE的接入效率。
本发明实施例的技术方案可以如下实现：

本发明实施例提供了一种信息传输方法、设备及计算机可读存储介质，UE接收系统消息关联信息，由于系统消息关联信息表征同步信号块所在的载波是否与系统消息存在关联关系，因此，该UE是可以根据系统消息关联信息，即当前接收的同步信号块所在的载波是否关联系统消息，以决定对系统信息进行处理时采取的方式，使得UE避免在同步信号块所在的载波与系统消息不存在关联关系时进行的系统信息的接收或者搜索的过程，从而节省UE的电量，还简化信息传输交互，进而提高了UE在接入过程中的接入效率。

具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
在本发明实施例中，由于5G NR中采用的频段相比长期演进(LTE，Long Term Evolution)系统所采用的频段更高，所以会造成无线信号传输的路径损耗变大，导致无线信号的覆盖变小。因此，在5G系统中，通过基站的多天线系统，采用波束成形beamforming技术形成波束beam来提高无线信号的增益，从而弥补无线信号传输中的路径损耗。
在5G NR系统中，公共信道和公共信号均通过多波束扫描的方式覆盖整个小区，以便于小区内的用户设备(UE，User Equipment)能够接收到公共信道和公共信号(例如，关联系统信息的同步信号)。这里，可以在授权频谱上使用NR系统或在免授权频谱使用NR系统。而本发明实施例是在免授权频谱上使用NR系统的背景下实现的信息传输方法。
可以理解的是，上述NR系统应用于免授权频谱可以为2.4GHz，5GHz，37GHz或60GHz的频谱等。
当本发明实施例中的NR系统应用于免授权频谱，且布网场景是独立部署(SA，StandAlone)场景时，用户设备可以通过免授权频谱接入网络。
示例性的，参见图1，其示出了非典型示例的通信系统1的结构示意，通信系统可以由用户设备1-1、1-2和1-3和网络侧设备2组成，用户设备与网络侧设备之间分别通过无线链路进行通信，如图1中的双向箭头所示。在图1中，本发明实施例中的用户设备可以为接入终端、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。这里的用户设备可以是第五代通信(fifth-generation，简称“5G”)网络中的终端设备。
网络侧设备2可以是用于与用户设备通信的设备，这里的网络侧设备可以NR网络中的网络设备，例如5G基站(gNB)。
在本发明实施例中，网络侧设备为小区提供服务，用户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)与网络侧设备进行通信，该小区可以是网络侧设备(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。
基于上述说明内容，提出以下实施例。
实施例一
本发明实施例提供了一种信息传输方法，应用于UE侧，如图2所示，该方法可以包括：
S101、接收系统消息关联信息；系统消息关联信息表征同步信号块所在的载波是否与系统消息存在关联关系。
在本发明实施例中，网络侧设备是可以发送当前同步信号块所在的当前载波是否在当前时刻与系统消息存在关联的指示信息的，即系统消息关联关系，在UE接收到该系统消息关联关系的时候，该UE就可以获知接收 的当前同步信号块此时所在的载波是否存在与系统信息(在系统消息中)相关联的信息了。
需要说明的是，在本发明实施例中，UE与网络侧设备是以公共信号(例如同步信号(SS，synchronization signal))传输的方式实现通信的。在免授权频谱上使用NR系统实现的信号传输时，用户设备可以通过接收网络侧设备发送的同步信号块实现系统消息中系统信息的获取，进而进行网络接入的。
具体来说，在5G NR系统中，同步信号和广播信道，需要通过多波束扫描的方式覆盖整个小区，便于小区内的UE接收。同步信号(SS，synchronization signal)在多波束发送时，通过定义同步信号突发组SS burst set来实现的。一个SS burst set包含一个或者多个SS burst，一个SS burst包含一个或多个同步信号块(SS block，Synchronization Signal block)。一个SS block用于承载一个波束的同步信号和广播信道。因此，一个SS burst set可以包含小区内同步信号快数量SS block number相同个数的波束的同步信号。一个SS block中包含一个符号的主同步信号(PSS，Primary Synchronization Signal)、一个符号的辅同步信号(SSS，Secondary Synchronization Signal))和两个符号的物理广播信道(NR-PBCH，New Radio Access Technology-Physical broadcast channel)。具体的SS block的结构示意图参见图3。除了同步信号和PBCH需要进行多波束扫描，其他的一些公共信息，如剩余最小系统信息(RMSI，Remaining Minimum System Information)，寻呼(paging)消息，也需要通过多波束扫描的方式发送。
这里，同步信号可以由网络侧设备配置给UE；并且SS block用于无线资源管理RRM和移动性测量。
需要说明的是，在本发明实施例中，由于在免授权频谱的载波上进行信息传输时，可能是在SA场景下进行的，也可能是在NSA场景下进行的， 因此，本发明实施例中的系统消息关联信息还可以认为是UE当前接收的同步信号块是在SA场景下传输的，还是在NSA场景下传输的意思。
也就是说，在本发明实施例中，系统消息关联信息包括：同步信号块所在的载波为SA载波，或者，同步信号块所在的载波为NSA载波。
需要说明的是，SA的系统在当前载波上发送同步信号块时，表征该同步信号块所在的当前载波为SA载波，而NSA的系统在当前载波上发送同步信号块时，表征该同步信号块所在的当前载波为NSA载波。本发明实施例中的SA载波和NSA载波的定义是针对当前同步信号块而言的当前时刻的状态的表征，并不是表征当前载波的类型就是固定的SA或NSA的意思，当前载波是随着发送当前同步信号块的系统决定的，是可以在不同的使用场景下表征不同含义的。
本发明实施例不限制系统消息关联信息的承载方式。示例性的，在本发明实施例中，UE接收的系统消息关联信息，是通过PBCH承载的，即通过PBCH承载系统消息关联信息。这样，UE就可以通过解析获取PBCH承载系统消息关联信息了。
需要说明的是，在本发明实施例中，UE在接入NR系统的时候，网络侧设备可以发送同步信号块给UE，以便UE可以通过该同步信号块可以获取到系统信息，进而根据系统信息实现网络接入。
详细地，UE接收第一同步信号块(即当前同步信号块)，获取第一SSB中承载的PBCH，进而获取PBCH承载的系统消息关联信息。
在本发明实施例中，通过PBCH承载系统消息关联信息的方式是不限定的，示例性的，可以采用以下至少一种方式：
(1)、通过PBCH承载的剩余最小系统信息对应的物理下行控制信道资源信息域来承载系统消息关联信息。
(2)、通过PBCH承载的物理资源块栅格偏移信息域中的保留值来承 载系统消息关联信息。
在(1)的实现方式中，网络侧设备是采用PBCH承载的剩余最小系统信息对应的物理下行控制信道资源信息域实现对系统消息关联信息的承载的，因此，UE可以通过解析获取的同步信号块中的剩余最小系统信息对应的物理下行控制信道资源信息域就可以或者系统消息关联信息了。
需要说明的是，对于RMSI来说，在5G NR系统中，对于初始接入的UE，需要定义一个common search space用于接收公共控制信息，例如RMSI。因此，引入了控制资源集(CORESET，Control Resource Set)的概念，用于定义承载控制信息的资源集合，UE在该资源集合中检测NR-PDCCH信道，以获得承载RMSI的NR-PDSCH的调度信息。CORESET的指示信息指示了PDCCH的资源集合信息，CORESET的指示信息通过NR-PBCH中的RMSI-PDCCH-Config控制信息域的承载，以便UE接收RMSI。因此，CORESET的指示信息是承载在RMSI-PDCCH-Config信息域，即剩余最小系统信息对应的物理下行控制信道资源信息域，CORESET的指示信息具体指示Type0-PDCCH common search space的信息，故在本发明实施例中，剩余最小系统信息对应的物理下行控制信道资源信息域可以表示为RMSI-PDCCH-Config信息域，也可以采用可指示出或表征出剩余最小系统信息对应的物理下行控制信道资源信息域的CORESET，即Type0-PDCCH common search space的指示信息来替代。
详细的，网络侧设备是采用RMSI-PDCCH-Config信息域的8比特指示系统消息关联信息的，这样UE就可以在RMSI-PDCCH-Config信息域中的8比特中获取系统消息关联信息了。
在(2)的实现方式中，网络侧设备是采用PBCH承载的物理资源块栅格偏移信息域中的保留值实现对系统消息关联信息的承载的，因此，UE可以通过解析获取的同步信号块中的物理资源块栅格偏移信息域中的保留值 就可以或者系统消息关联信息了。
在本发明实施例中，PBCH承载的物理资源块栅格偏移信息域中的保留值可以表示为PRB grid offset信息域中的保留值，或者表示为k SSB。
需要说明的是，网络侧设备采用物理资源块栅格偏移信息域中的哪个保留值承载系统消息关联信息本发明实施例是可以不作限制的。
优选的，物理资源块栅格偏移信息域中的保留值可以为14或30，理由如下：
在现有的k SSB中，如表1和表2所示，只有k SSB为14或30的为未被占用的保留值，因此，最优的是选择未被占用的保留值来进行新信息(系统消息关联信息)的指示，这样，可以在兼容现有的指示方式的基础上，添加上本发明实施例提出的系统消息关联信息的指示，保证了信息传输方式上的兼容性。其中，表1和表2表征现有技术中的采用RMSI-PDCCH-Config和k SSB联合指示目标SSB对应的sync raster的GSCN参数相比当前SSB对应的sync raster的GSCN参数的偏移情况(即

)的。表1是针对FR(frequency range)1的，表2是针对FR 2的。
表1
Figure PCTCN2018081234-appb-000002
表2
Figure PCTCN2018081234-appb-000003
需要说明的是，在本发明实施例中，还可以采用(1)和(2)两种方式共同指示系统消息关联信息。
S102、根据系统消息关联信息，对系统信息进行处理。
网络侧设备在获取到系统消息关联信息之后，就可以依据系统消息关联信息，获知当前接收的同步信号块中是否指示有系统消息相关信息了，以便UE决定是怎样进行对系统消息的系统信息的处理了。
详细的，UE根据系统消息关联信息，对系统信息进行处理的过程可以包括：S1021-S1022。如下：
S1021、系统消息关联信息表征同步信号块所在的载波与系统消息存在关联关系时，进行系统信息的接收。
S1022、系统消息关联信息表征同步信号块所在的载波与系统消息未存在关联关系时，不通过接收的当前同步信号块来接收系统信息。
在本发明实施例中，系统消息关联信息包括：同步信号块所在的载波为SA载波，或者，同步信号块所在的载波为NSA载波。也就是说，UE获取的系统消息关联信息要么是指示同步信号块所在的当前载波为NSA载波，要么是指示同步信号块所在的当前载波为NSA载波。而针对使用免授权频谱时，在NSA场景下发送的SSB，是不会存在指示系统信息的相关信息的，只有在SA场景下，才会存在指示系统信息的相关信息。也就是说， 当系统消息关联信息包括的是NSA载波时，系统消息关联信息表征同步信号块所在的载波与系统消息未存在关联关系，这时，UE是不通过接收的当前同步信号块来接收系统信息。而当系统消息关联信息包括的是SA载波时，系统消息关联信息表征同步信号块所在的载波与系统消息存在关联关系，这时，UE进行系统信息的接收处理。
可以理解的是，对于使用免授权频谱的SA场景下的UE，通过网络侧设备发送的SSB指示出该SSB属于SA载波还是NSA载波，从而UE可以确定是否通过该SSB中指示的上述信息来继续接收系统消息或者关联系统消息的SSB，避免了当前同步信号块所在载波为NSA载波时，UE还在进行系统消息或系统信息的搜索行为，从而减少了UE接收系统消息的复杂度和耗电量，即UE接收系统消息关联信息，由于系统消息关联信息表征同步信号块所在的载波是否与系统消息存在关联关系，因此，该UE是可以根据系统消息关联信息，即当前接收的同步信号块所在的载波是否关联系统消息，以决定对系统信息进行处理时采取的方式，使得UE避免在同步信号块所在的载波与系统消息不存在关联关系时进行的系统信息的接收或者搜索的过程，从而节省UE的电量，还简化信息传输交互，进而提高了UE在接入过程中的接入效率。
实施例二
基于前述实施例相同的发明构思，本发明实施例提供了一种信息传输方法，应用于网络侧设备中，该方法可以包括：
S201、发送系统消息关联信息至UE，系统消息关联信息表征同步信号块所在的载波是否与系统消息存在关联关系。
在本发明实施例中，网络侧设备是可以获知当前采用的SA场景还是NSA场景的，因此，该网络侧设备就可以获知是SA的系统在当前载波上发送同步信号块(即同步信号块所在的载波是SA载波)，还是NSA的系统 在当前载波上发送同步信号(即同步信号块所在的载波是NSA载波)，于是就网络侧设备可以将同步信号块此时所在的载波是在什么场景下的告知给UE，而由于在SA场景下，同步信号块所在的载波是否与系统消息存在关联关系；NSA场景下，同步信号块所在的载波是否与系统消息你存在关联关系的，因此，网络侧设备就采用系统消息关联信息来表征同步信号块所在的载波是否与系统消息存在关联关系，并将系统消息关联信息发送给UE，便于UE根据系统消息关联信息实现对系统信息的处理。
在本发明的一些实施例中，如图4所示，本发明实施例提供的信息传输方法在S201之前，还可以包括：S202。如下：
S202、将系统消息关联信息承载在PBCH中。
在本发明实施例中，网络侧设备会发送第一SSB(当前同步信号块)至UE，该第一SSB中承载PBCH，网络侧设备是采用PBCH承载系统消息关联信息，以便将系统消息关联信息发送给UE的。
在本发明实施例的一种可能实现的方式中，网络侧设备可以将PBCH承载的剩余最小系统信息对应的物理下行控制信道资源信息域作为系统消息关联信息。
在本发明实施例的另一种可能实现的方式中，网络侧设备可以将PBCH承载的物理资源块栅格偏移信息域中的保留值作为系统消息关联信息。
优选的，物理资源块栅格偏移信息域中的保留值为14或30，本发明实施例可不作限制。
需要说明的是，网络侧设备具体的实现系统消息的承载过程和具体的实现等在实施例一中已经进行了详细的描述，此处不在赘述。
进一步地，示例性的，基于实施例一和实施例二的发明构思下，本发明实施例提供了一种信息传输方法，如图5所示，该方法可以包括：
S301、网络侧设备将系统消息关联信息承载在PBCH中，系统消息关 联信息表征同步信号块所在的载波是否与系统消息存在关联关系。
S302、网络侧设备发送系统消息关联信息至UE。
S303、UE根据系统消息关联信息，对系统信息进行处理。
这里，S301-S303的详细实现过程已在前述的实施例中已经进行了详细的描述，此处不再赘述。
可以理解的是，网络侧设备可以通过PBCH承载系统消息关联信息，由于系统消息关联信息表征同步信号块所在的载波是否与系统消息存在关联关系，使得UE接收到网络侧设备发送的系统消息关联信息时，该UE是可以根据系统消息关联信息，即当前接收的同步信号块所在的载波是否关联系统消息，以决定对系统信息进行处理时采取的方式，使得UE避免在同步信号块所在的载波与系统消息不存在关联关系时进行的系统信息的接收或者搜索的过程，从而节省UE的电量，还简化信息传输交互，进而提高了UE在接入过程中的接入效率。

另外，在本实施例中的各组成部分可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。
所述集成的单元如果以软件功能模块的形式实现并非作为独立的产品进行销售或使用时，可以存储在一个计算机可读取存储介质中，基于这样的理解，本实施例的技术方案本质上或者说对现有技术做出贡献的部分或者该技术方案的全部或部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)或processor(处理器)执行本实施例所述方法的全部或部分步骤。而前述的存储介质包括：磁性随机存取存储器(ferromagnetic random access memory，FRAM)、只读存储器(Read Only Memory，ROM)、可编程只读存储器(Programmable Read-Only Memory，PROM)、可擦除可编程只读存储器(Erasable Programmable Read-Only Memory，EPROM)、电可擦除可编程只读存储器(Electrically  Erasable Programmable Read-Only Memory，EEPROM)、快闪存储器(Flash Memory)、磁表面存储器、光盘、或只读光盘(Compact Disc Read-Only Memory，CD-ROM)等各种可以存储程序代码的介质，本发明实施例不作限制。

可以理解的是，UE接收系统消息关联信息，由于系统消息关联信息表征同步信号块所在的载波是否与系统消息存在关联关系，因此，该UE是可以根据系统消息关联信息，即当前接收的同步信号块所在的载波是否关联系统消息，以决定对系统信息进行处理时采取的方式，使得UE避免在同步信号块所在的载波与系统消息不存在关联关系时进行的系统信息的接收或者搜索的过程，从而节省UE的电量，还简化信息传输交互，进而提高了UE在接入过程中的接入效率。

因此，如图9所示，本发明实施例还提供了一种网络侧设备，包括：第二网络接口23、第二存储器24和第二处理器22。其中，
所述第二网络接口23，用于在与其他外部网元之间进行收发信息过程中，信号和信息的接收和发送。
所述第二存储器24，用于存储能够在第二处理器22上运行的计算机程序。
所述第二处理器22，用于在运行所述计算机程序时，执行网络侧设备所述的信息传输方法的步骤。
需要说明的是，在实际应用时，网络侧设备中的各个组件通过通信总线耦合在一起。可以理解的是，通信总线用于实现这些组件之间的连接通 信。通信总线除包括数据总线之外，还包括电源总线、控制总线和状态信号总线。但是为了清楚说明起见，可将各种总线都称为通信总线。
同样的，在网络侧设备中与UE一样的考虑，网络侧设备中的计算机软件产品可存储在一个存储介质中，此处不再赘述理由。
这样，本发明实施例提供了一种计算机可读存储介质，所述计算机可读存储介质存储有信息传输的程序，所述信息传输的程序被至少一个第二处理器执行实现网络侧设备所述的信息传输方法的步骤。
可以理解的是，网络侧设备可以通过PBCH承载系统消息关联信息，由于系统消息关联信息表征同步信号块所在的载波是否与系统消息存在关联关系，使得UE接收到网络侧设备发送的系统消息关联信息时，该UE是可以根据系统消息关联信息，即当前接收的同步信号块所在的载波是否关联系统消息，以决定对系统信息进行处理时采取的方式，使得UE避免在同步信号块所在的载波与系统消息不存在关联关系时进行的系统信息的接收或者搜索的过程，从而节省UE的电量，还简化信息传输交互，进而提高了UE在接入过程中的接入效率。
以上所述，仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。
工业实用性
UE接收系统消息关联信息，由于系统消息关联信息表征同步信号块所在的载波是否与系统消息存在关联关系，因此，该UE是可以根据系统消息关联信息，即当前接收的同步信号块所在的载波是否关联系统消息，以决定对系统信息进行处理时采取的方式，使得UE避免在同步信号块所在的载波与系统消息不存在关联关系时进行的系统信息的接收或者搜索的过程，从而节省UE的电量，还简化信息传输交互，进而提高了UE在接入过程中的接入效率。
