Description

系统信息发送方法、系统信息接收方法及装置 技术领域
本公开实施例涉及通信技术领域，特别涉及一种系统信息发送方法、系统信息接收方法及装置。
背景技术
在LTE(Long-Term Evolution，长期演进)系统中，基站通过广播的方式向UE(User Equipment，用户设备)发送系统信息(System Information，SI)。系统信息包括UE接入基站时所需使用的信息，比如：下行带宽参数、系统帧号、小区重选信息等。
为了使得UE接收系统信息时能够获得较好的信号质量，在第五代移动通信技术(the 5th generation mobile communication，5G)中，基站通过波束赋形的方式向该小区内的每个UE发送系统信息。其中，5G系统又称新空口系统(new radio，NR)系统。波束赋形是基于天线阵列的信号预处理技术，波束赋形通过调整天线阵列中每个阵元的加权系数产生具有指向性的波束，从而使得位于小区中不同方向上的UE能够以较高的信号强度接收到系统信息。
当基站通过波束赋形的方式向小区内的各个UE发送系统信息时，对于位置和距离相差较大的不同UE，基站可能需要进行多次波束赋形来向这些UE发送系统信息，随着UE数量的增多，基站通过波束赋形发送系统信息的次数增多，基站的工作负荷较重。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
在本文提及的“模块”通常是指存储在存储器中的能够实现某些功能的程序或指令；在本文中提及的“单元”通常是指按照逻辑划分的功能性结构，该“单元”可以由纯硬件实现，或者，软硬件的结合实现。
在本文中提及的“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，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。
请参考图1，其示出了一个实施例提供的移动通信系统的结构示意图。该移动通信系统可以是5G系统，又称NR系统。该移动通信系统包括：接入网设备120和终端140。
接入网设备120可以是基站。例如，基站可以是5G系统中采用集中分布式架构的基站，比如，gNB。当接入网设备120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对接入网设备120的具体实现方式不加以限定。
接入网设备120和终端140通过无线空口建立无线连接。可选地，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口(New Radio，NR)；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
终端140可以是指向用户提供语音和/或数据连通性的设备。终端可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端140可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。例如，订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access  Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户装置(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户终端(User Equipment)。
需要说明的是，在图1所示的移动通信系统中，可以包括多个接入网设备120和/或多个终端140，图1中以示出一个接入网设备120和一个终端140来举例说明，但本实施例对此不作限定。
请参考图2所示的接入网设备140向终端120发送系统信息的示意图。在5G系统中，系统信息被划分成最小化系统信息(Minimum SI)和其它系统信息(Other SI)。
Minimum SI通过周期性广播的形式由接入网设备120发送给终端140。Minimum SI包括终端120接入接入网设备140时需要使用的基本信息，比如：下行小区宽带信息、系统帧号、随机接入参数等，本实施例对此不作限定。
Other SI可以通过波束赋形或周期性广播的形式由接入网设备120发送给终端140，本实施例以接入网设备120将Other SI通过波束赋形发送给终端140来举例说明。Other SI包括除最小化系统信息之外的所有系统信息，比如：小区重选信息、邻小区相关信息等。
在5G系统中，为了保证终端能够以较高的信号质量接收其它系统信息，对于高频段(比如6GHz以上的频段)的数据，接入网设备通常通过多次波束赋形向多个终端发送Other SI，相应地，终端接收接入网设备通过波束赋形发送的Other SI。
在5G系统中，接入网设备120通过上行链路接收终端140发送系统信息请求时，接入网设备120可以在具有不同窗口长度的n个连续的第一SI传输窗口中接收该系统信息请求；在终端140通过下行链路接收接入网设备120发送的系统信息时，终端140可以在具有不同窗口长度的n个连续的第二SI传输窗口中接收该系统信息。不同窗口长度可以是X个符号、Y个时隙、Z个TTI中的至少一种。其中，第一SI传输窗口和第二SI传输窗口是指用于传输SI的时频资源的资源位置。
请参考图3，其示出了一个实施例提供的系统信息传输方法的流程图。本实施例以该系统信息传输方法应用于图1所示的移动通信系统中来举例说明。 该方法包括：
在步骤301中，终端在第一SI传输窗口向接入网设备发送系统信息请求。
本实施例中，至少一个终端通过N个连续的第一SI传输窗口向接入网设备发送的系统信息请求，使得接入网设备根据该系统信息请求向该终端发送Other SI，而无需同时向所有终端发送Other SI，节省了接入网设备的信令资源，N为正整数。其中，系统信息请求用于请求接入网设备向终端发送Other SI。
N个第一SI传输窗口是指N个连续的第一SI传输窗口。可选地，第一SI传输窗口的窗口信息是终端与接入网设备预先协定的，比如在5G通信标准中约定的窗口信息。其中，窗口信息用于指示第一SI传输窗口的窗口长度和/或窗口个数。比如：如图4所示的第一SI传输窗口，该第一SI传输窗口的窗口信息包括：4个第一SI传输窗口，每个第一SI传输窗口的窗口长度为预定大小。
可选地，为了保证终端能够及时接收到Other SI，N个第一SI传输窗口连续，且互不重叠。
对于发送系统信息请求的每个终端来说，终端在N个连续的第一SI传输窗口中的一个窗口向接入网设备发送系统信息请求，比如：终端在N个连续的第一SI传输窗口的第二个第一SI传输窗口(图中窗口2)上发送系统信息请求。
在步骤302中，接入网设备在第一SI传输窗口接收终端发送的系统信息请求。
接入网设备在N个连续的第一SI传输窗口接收至少一个终端发送的系统信息请求。
可选地，接入网设备在单个第一SI传输窗口中接收一个终端发送的系统信息请求，或者，在单个第一SI传输窗口中接收多个终端发送的系统信息请求。
在步骤303中，接入网设备在第二SI传输窗口向终端发送其它系统信息。
接入网设备接收到的第一SI传输窗口中的系统信息请求后，根据第一SI传输窗口和第二SI传输窗口的定时关系，确定出发送Other SI的第二SI传输窗口。
其中，第一SI传输窗口和第二SI传输窗口的定时关系是指：第二SI传输窗口是第一SI传输窗口之后的第M个传输窗口，M的值通常大于或等于第一 SI传输窗口的数量N。其中，第一SI传输窗口之后的第M个传输窗口是指：以接收到系统信息请求的传输窗口为起始传输窗口，在该起始传输窗口之后的第M个传输窗口。换句话说，若接入网设备在第i个SI传输窗口接收到终端的系统信息请求，则接入网设备在第i+M个SI传输窗口中向终端发送Other SI。
可选地，第一SI传输窗口和第二SI传输窗口的定时关系是接入网设备与终端预先协定的，或者，5G通信标准所定义的。
可选地，第二SI传输窗口的窗口信息是接入网设备与终端预先协定的，或者，5G通信标准所定义的。第二SI传输窗口连续，且互不重叠。另外，第二SI传输窗口在第一SI传输窗口之后，第二SI传输窗口与第一SI传输窗口之间可以连续，也可以不连续，本实施例对此不作限定。
示意性的，第一SI传输窗口与第二SI传输窗口如图5所示，第一SI传输窗口为连续的5个SI传输窗口，第二SI传输窗口在第一SI传输窗口之后，且第二SI传输窗口也是连续的5个SI传输窗口。当接入网设备通过第i个SI传输窗口接收到终端发送的系统信息请求时，则通过第i+M个SI传输窗口向终端发送Other SI。
在步骤304中，终端在第二SI传输窗口接收接入网设备发送的其它系统信息。
由于第二SI传输窗口的窗口信息、第一SI传输窗口与第二SI传输窗口之间的定时关系是接入网设备与终端预先协定的。因此，终端在通过第一SI传输窗口发送系统信息请求后，直接通过第一SI传输窗口之后的第M个SI传输窗口接收该Other SI，无需接入网设备发送额外的信令向终端通知第二SI传输窗口的窗口位置，节省了接入网设备的信令资源。
综上所述，本公开实施例提供的系统信息传输方法，通过终端在第一SI传输窗口发送系统信息请求；接入网设备在该SI传输窗口接收该系统信息请求，并根据该系统信息请求在第二SI传输窗口向该终端发送其它系统信息；该终端在该第二SI传输窗口接收该其它系统信息；解决了接入网设备通过多次波束赋形向所有终端发送其它系统信息时，接入网设备的信令负担较大的问题；由于接入网设备只需要向发送了系统请求信息的终端反馈其它系统信息，而无需向所有终端发送其它系统信息，降低了接入网设备的信令负担。
另外，通过接入网设备与终端预先协定第一SI传输窗口的窗口信息、第二SI传输窗口的窗口信息和第一SI传输窗口与第二SI传输窗口之间的定时关 系，使得接入网设备无需向终端额外发送信令，即可保证发送了系统请求信息的终端能够成功接收到其它系统信息，进一步地降低了接入网设备的信令负担。
可选地，步骤301和304可单独实现为终端侧的系统信息接收方法的实施例，步骤302和303可单独实现为接入网设备侧的系统信息发送方法的实施例，本实施例对此不作限定。
基于图3所示的实施例，第一SI传输窗口的窗口信息和第二SI传输窗口的窗口信息是固定不变的。在可选的实施例中，接入网设备可以向终端指示第一SI传输窗口和第二SI传输窗口的窗口信息，此时，第二SI传输窗口的窗口信息是可变的。可选地，接入网设备以系统广播的方式，向终端指示第一SI传输窗口和第二SI传输窗口的窗口信息。
请参考图6，其示出另一个实施例提供的系统信息传输方法的流程图。本实施例以该系统信息传输方法应用于图1所示的移动通信系统中来举例说明。该方法包括：
在步骤601中，接入网设备根据负载和/或终端的业务时延需求，确定第一SI传输窗口和第二SI传输窗口的窗口长度和窗口数量。
当接入网设备根据负载确定第一SI传输窗口的窗口信息和第二SI传输窗口的窗口信息时，接入网设备获取接入网设备当前的负载，比如，该负载用于指示已接入接入网设备的终端数量；根据该负载确定该第一SI传输窗口的窗口信息和第二SI传输窗口的窗口信息。其中，第一SI传输窗口和第二SI传输窗口的窗口长度与负载呈正相关关系；第一SI传输窗口和第二SI传输窗口的连续窗口个数与负载呈正相关关系。也即，负载越重，则第一SI传输窗口的窗口长度越大，连续窗口个数N也越大；负载越轻，则第一SI传输窗口的窗口长度越小，连续窗口个数N也越小。
当接入网设备根据终端的业务时延需求确定第一SI传输窗口的窗口信息和第二SI传输窗口的窗口信息时，接入网设备获取终端的业务类型，根据该业务类型确定时延需求；根据该时延需求确定该第一SI传输窗口的窗口信息和第二SI传输窗口的窗口信息。其中，时延需求越高，则第一SI传输窗口和第二SI传输窗口的窗口长度越短；时延需求越低，则第一SI传输窗口和第二SI传输窗口的窗口长度越长。
在步骤602中，接入网设备通过最小化系统信息向终端发送第一SI传输窗口的窗口长度和窗口数量；和/或，接入网设备通过最小化系统信息向终端发送第二SI传输窗口的窗口长度和窗口数量。
可选地，接入网设备在最小化系统信息中指示第一SI传输窗口的窗口长度和窗口数量和第二SI传输窗口的窗口长度和窗口数量；或者，在最小化系统信息中指示第一SI传输窗口的窗口长度和窗口数量；或者，在一条最小化系统信息中指示第二SI传输窗口的窗口长度和窗口数量，本实施例对此不作限定。
第一SI传输窗口连续且互不重叠；第二SI传输窗口连续且互不重叠，第二SI传输窗口在第一SI传输窗口之后，且第二SI传输窗口与SI传输窗口之间可以连续，也可以不连续，本实施例对此不作限定。
在步骤603中，终端接收接入网设备发送的最小化系统信息。
在步骤604中，终端获取最小化系统信息中的第一SI传输窗口的窗口长度和窗口数量；和/或，终端获取最小化系统信息中的第二SI传输窗口的窗口长度和窗口数量。
在步骤605中，终端在第一SI传输窗口向接入网设备发送系统信息请求。
对于发送系统信息请求的每个终端来说，终端在N个连续的第一SI传输窗口中的一个窗口向接入网设备发送系统信息请求。
在步骤606中，接入网设备在第一SI传输窗口接收终端发送的系统信息请求。
接入网设备在N个连续的第一SI传输窗口接收终端发送的系统信息请求。
在步骤607中，接入网设备在第二SI传输窗口向终端发送其它系统信息。
在步骤608中，终端在第二SI传输窗口接收接入网设备发送的其它系统信息。
由于第一SI传输窗口的窗口信息和第二SI传输窗口的窗口信息是接入网设备确定后发送给终端的、第一SI传输窗口与第二SI传输窗口之间的定时关系是接入网设备与终端预先协定的或5G通信标准所定义的，因此，终端在通过第一SI传输窗口发送系统信息请求后，直接通过第一SI传输窗口之后的第M个SI传输窗口接收Other SI即可，无需接入网设备发送额外的信令通知终端接收该其它系统信息的第二SI传输窗口，节省了接入网设备的信令资源。
综上所述，本公开实施例提供的系统信息传输方法，通过接入网设备根据 负载确定第一传输窗口的窗口长度和窗口数量和第二传输窗口的窗口长度和窗口数量；通过最小化系统信息向终端发送第一SI传输窗口的窗口长度和窗口数量；和/或，第二SI传输窗口的窗口长度和窗口数量；由于第一传输窗口和第二传输窗口的窗口长度与负载数量呈正相关关系；第一传输窗口和第二传输窗口的窗口个数与负载数量呈正相关关系，使得接入网设备在负载较重时，可以以较长的时间间隔向终端发送其它系统信息，降低了接入网设备的信令负担。
另外，通过接入网设备根据业务时延需求确定第一传输窗口的窗口长度和窗口数量和第二传输窗口的窗口长度和窗口数量，通过最小化系统信息向终端发送第一SI传输窗口的窗口长度和窗口数量；和/或，第二SI传输窗口的窗口长度和窗口数量；由于时延需求越高对应的第一SI传输窗口和第二SI传输窗口的窗口长度越短；且时延需求越低对应的第一SI传输窗口和第二SI传输窗口的窗口长度越长，使得接入网设备发送其它系统信息时，可以尽量地满足终端的业务时延需求，保证了接入网设备发送其它系统信息的及时性。
可选地，步骤602、606和607可单独实现为接入网设备侧的系统信息发送方法的实施例，步骤601、603-605和608可单独实现为终端侧的系统信息发送方法的实施例，本实施例对此不作限定。
基于图3和图6所示的实施例，第一SI传输窗与第二SI传输窗口之间的定时关系是预先协定的或5G通信标准所定义的，即该定时关系是固定不变的。在可选的实施例中，接入网设备通过第一传输窗口接收到系统信息请求后，动态配置用于发送Other SI的第二传输窗口，并向终端指示该第二传输窗口的窗口位置，此时，第一SI传输窗与第二SI传输窗口之间的定时关系是动态可变的。可选地，接入网设备可以通过向终端发送下行调度信息，向终端指示第二传输窗口的窗口位置。
请参考图7，其示出了另一个实施例提供的系统信息传输方法的流程图。本实施例以该系统信息传输方法应用于图1所示的移动通信系统中来举例说明。该方法包括：
在步骤701中，终端在第一SI传输窗口向接入网设备发送系统信息请求。
第一SI传输窗口的窗口信息可以是终端与接入网设备预先协定的，此时，请参考步骤301中的相关描述；或者，第一传输窗口窗口信息可以是接入网设 备通过最小化系统信息发送给终端的，此时，请参考步骤601-605中的相关描述。
在步骤702中，接入网设备在第一SI传输窗口接收终端发送的系统信息请求。
本步骤的相关描述参见步骤302或步骤606，本实施例在此不作赘述。
在步骤703中，接入网设备向终端发送下行调度信息，该下行调度信息用于指示第二SI传输窗口是第一SI传输窗口之后的第M个SI传输窗口。
M的值是根据接入网设备的负载确定的，和/或，根据终端的业务时延需求确定的。
当M是根据接入网设备的负载确定的时，接入网设备获取负载数量；根据该负载数量确定M的值。其中，M与负载数量呈正相关关系。
当M是根据终端的业务时延需求确定的时，接入网设备获取发送系统信息请求的终端的业务类型，根据该业务类型确定时延需求；根据该时延需求确定M的值。其中，时延需求越高M的值越大。
可选地，下行调度信息还可以用于指示第K个SI传输窗口，该第K个SI传输窗口是接入网设备接收系统信息请求的第一SI传输窗口之后的第M个SI传输窗口。
在步骤704中，终端接收接入网设备发送下行调度信息。
在步骤705中，接入网设备在下行调度信息指示的第二SI传输窗口向终端发送其它系统信息。
第二SI传输窗口是接入网设备接收到系统信息请求的第一SI传输窗口之后的第M个传输窗口。
在步骤706中，终端在下行调度信息指示的第二SI传输窗口接收接入网设备发送的其它系统信息。
综上所述，本实施例提供的系统信息传输方法，通过接入网设备根据负载确定发送其它系统信息的第二传输窗口，由于负载越重，第一传输窗口之后的第M个传输窗口的M的值越大，因此，当接入网设备的负载较重时，可以延缓向终端发送其它系统信息，降低了接入网设备的信令负担。
另外，通过接入网设备根据发送系统请求信息的终端的业务延时需求，确定发送其它系统信息的第二传输窗口，由于系统延时需求越高，第一传输窗口之后的第M个传输窗口的M的值越小，因此，当发送系统信息请求的业务延 时需求较高时，接入网设备可以及时地向该终端发送其它系统信息，保证了接入网设备发送其它系统信息的及时性。
可选地，步骤701、704、706可单独实现为终端侧的系统信息接收方法的实施例，步骤702、703和705可单独实现为接入网设备侧的系统信息发送方法的实施例，本实施例对此不作限定。
