具体实施方式
针对现有技术中存在的问题，本发明中提出一种适用于中继场景下的系统信息发送方式，主要涉及到基站(gNB)、中继节点以及末端节点之间的交互。
为了使本发明的技术方案更加清楚、明白，以下参照附图并举实施例，对本发明所述方案进行进一步说明。
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，本领域技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
图1为本发明所述系统信息发送方法第一实施例的流程图。如图1所示，包括以下具体实现方式。
在101中，中继节点获取gNB广播的MSI，将MSI转发给所服务的末端节点。
在中继场景下，gNB广播的MSI被中继节点接收到后，如果中继节点支持中继功能，包括但不限于同步源功能，中继节点会对MSI进行转 发，即将MSI转发给所服务的末端节点。
MSI中可进一步携带有OSI调度信息，相应地，末端节点获取OSI调度信息。
在102中，中继节点获取末端节点的按需系统信息需求，向gNB请求按需系统信息。
对于处于非连接态的末端节点来说，在获取到中继节点转发的MSI及OSI调度信息等之后，可根据当前小区已经广播的系统信息，确定是否需要请求所需的其它系统信息，即是否有按需系统信息需求。非连接态可包括空闲态和非激活态等。
如果有按需系统信息需求，则末端节点可通过与中继节点之间的交互，使得中继节点获知末端节点的按需系统信息需求，所述交互可以通过非蜂窝(non-cellular)或蜂窝(cellular)链路进行。
中继节点可对获取到的各末端节点的按需系统信息需求进行汇总，并根据汇总结果，统一向gNB进行请求。
比如，中继节点共获取到了末端节点a和末端节点b两个末端节点的按需系统信息需求，其中，末端节点a所需的按需系统信息为按需系统信息1和按需系统信息2，末端节点b所需的按需系统信息为按需系统信息2和按需系统信息3，那么中继节点则需要向gNB请求按需系统信息1、按需系统信息2和按需系统信息3。
中继节点向gNB请求按需系统信息的方式可包括：
1)中继节点通过随机接入方式向gNB请求按需系统信息；
2)中继节点通过无线资源控制(RRC)专用信令方式向gNB请求按需系统信息。
中继节点可任选上述方式1)或2)来向gNB请求按需系统信息。
在103中，中继节点将gNB下发的按需系统信息发送给对应的末端节点。
gNB可根据中继节点的请求，将末端节点所需的按需系统信息通过中继节点下发给对应的末端节点。
具体地，gNB可通过与中继节点之间的RRC连接将按需系统信息发送给中继节点，进而由中继节点通过与末端节点之间的连接将按需系统信息发送给对应的末端节点。
或者，gNB广播按需系统信息，进而由中继节点以RRC专用信令的方式，经过透明传输，将按需系统信息传输到对应的末端节点。
gNB可按照预定准则确定按需系统信息的下发方式。比如，如果当前的物理广播信道(PBCH)资源剩余率比物理下行共享信道(PDSCH)资源剩余率低，或者末端节点所需的按需系统信息仅是某一中继节点所服务的末端节点所需的，那么则可以采用前一种下发方式，即通过与中继节点之间的RRC连接将按需系统信息发送给中继节点，进而由中继节点通过与末端节点之间的连接将按需系统信息发送给对应的末端节点。再比如，如果末端节点所需的按需系统信息是多个中继节点所服务的末端节点所需的，或者，当前的PBCH资源剩余率大于预定阈值，那么则可采用后一种下发方式，即gNB广播按需系统信息，进而由中继节点以RRC专用信令的方式，经过透明传输，将按需系统信息传输到对应的末端节点。以上准则仅为举例说明，并不用于限制本发明的技术方案。
相应地，中继节点将gNB下发的按需系统信息发送给对应的末端节点的方式可包括：
1)中继节点获取gNB通过与中继节点之间的RRC连接发送来的按需系统信息，并通过中继节点与末端节点之间的连接将按需系统信息发送给对应的末端节点；
2)中继节点将gNB广播的按需系统信息以RRC专用信令的方式，经过中继节点的透明传输，传输到对应的末端节点。
上述实施例中，主要是对末端节点处于非连接态时的情况进行说明，如果末端节点处于连接态，那么中继节点可将获取自gNB的更新后的系统信息发送给处于连接态的末端节点。
可包括以下三种实现方式：
1)中继节点将gNB通过与末端节点之间的RRC连接发送给末端节点的系统信息透明传输给末端节点；
2)中继节点获取gNB通过与中继节点之间的RRC连接发送来的系统信息，并通过中继节点与末端节点之间的连接将系统信息发送给末端节点；
3)中继节点将gNB下发的寻呼消息中继给末端节点，并将gNB广播的系统信息中继给末端节点，以便末端节点根据寻呼消息从系统信息中读取相应的系统信息块。
对于方式3)，需要增强寻呼(paging)机制，将gNB的寻呼消息中继给末端节点，也将系统信息中继给末端节点，这种方式要求末端节点的寻呼时机(paging occasion)和不连续接收周期(DRX cycle)的配置不受中继及其所引入的延迟的影响。
图2为本发明所述系统信息发送方法第二实施例的流程图。如图2所示，包括以下具体实现方式。
在201中，gNB将MSI广播给中继节点，以便中继节点将MSI转发给所服务的末端节点。
在中继场景下，gNB广播的MSI被中继节点接收到后，中继节点会对MSI进行转发，即将MSI转发给所服务的末端节点。
在202中，gNB获取来自中继节点的按需系统信息请求，按需系统信息请求中携带有中继节点从末端节点中获取的按需系统信息需求。
中继节点可对所服务的处于非连接态的末端节点的按需系统信息需求进行汇总，并统一向gNB请求，即向gNB发送按需系统信息请求。
具体地，gNB获取来自中继节点的按需系统信息请求的方式可包括：
1)gNB获取中继节点通过随机接入方式发送来的按需系统信息请求；
2)gNB获取中继节点通过RRC专用信令方式发送来的按需系统信息请求。
根据获取到的按需系统信息请求，gNB即可获知中继节点请求了哪种或哪些按需系统信息。
在203中，gNB将按需系统信息通过中继节点下发给对应的末端节点。
gNB将按需系统信息通过中继节点下发给对应的末端节点的方式可包括：
1)gNB通过与中继节点之间的RRC连接将按需系统信息发送给中继节点，以便中继节点通过与末端节点之间的连接将按需系统信息发送给对应的末端节点；
2)gNB广播按需系统信息，以便中继节点以RRC专用信令的方式，经过透明传输，将按需系统信息传输到对应的末端节点。
gNB可按照预定准则确定按需系统信息的下发方式。比如，如果当前的PBCH资源剩余率比PDSCH资源剩余率低，或者末端节点所需的按需系统信息仅是某一中继节点所服务的末端节点所需的，那么则可以采用前一种下发方式，如果末端节点所需的按需系统信息是多个中继节点所服务的末端节点所需的，或者，当前的PBCH资源剩余率大于预定阈值，那么则可采用后一种下发方式。以上准则仅为举例说明，并不用于限制本发明的技术方案。
另外，gNB还可通过中继节点将更新后的系统信息发送给处于连接态的末端节点。
具体实现方式可包括：
1)gNB通过与末端节点之间的RRC连接将系统信息发送给末端节点，中继节点透明传输系统信息；
2)gNB通过与中继节点之间的RRC连接将系统信息发送给中继节点，以便中继节点通过与末端节点之间的连接将系统信息发送给末端节点；
3)gNB将寻呼消息通过中继节点中继给末端节点，并将广播的系统信息通过中继节点中继给末端节点，以便末端节点根据寻呼消息从系统信息中读取相应的系统信息块。
对于方式3)，需要增强paging机制，将gNB的寻呼消息中继给末端节点，也将系统信息中继给末端节点，这种方式要求末端节点的paging occasion和DRX cycle的配置不受中继及其所引入的延迟的影响。
图3为本发明所述系统信息发送方法第三实施例的流程图。如图3所示，包括以下具体实现方式。
在301中，末端节点通过中继节点获取gNB广播的MSI。
在中继场景下，gNB广播的MSI被中继节点接收到后，中继节点会对MSI进行转发，即将MSI转发给所服务的末端节点。
在302中，末端节点将按需系统信息需求发送给中继节点，以便中继节点向gNB请求按需系统信息。
末端节点处于非连接态且有按需系统信息需求时，可将按需系统信息需求发送给中继节点。非连接态可包括空闲态和非激活态等。
对于处于非连接态的末端节点来说，在获取到中继节点转发的信息后，可根据当前小区已经广播的系统信息，确定是否需要请求所需的其它系统信息，即是否有按需系统信息需求。
如果有按需系统信息需求，则末端节点可通过与中继节点进行交互，将按需系统信息需求发送给中继节点，从而使得中继节点获知末端节点的按需系统信息需求。
中继节点可对获取到的各末端节点的按需系统信息需求进行汇总，并根据汇总结果，统一向gNB进行请求。
在303中，末端节点通过中继节点获取gNB下发的按需系统信息。
末端节点通过中继节点获取gNB下发的按需系统信息的方式可包括：
1)末端节点获取中继节点通过与末端节点之间的连接发送来的按需系统信息，按需系统信息为gNB通过与中继节点之间的RRC连接发送给中继节点的；
2)末端节点获取gNB广播的按需系统信息，中继节点将gNB广播的按需系统信息以RRC专用信令的方式，经过中继节点的透明传输，传 输到末端节点。
另外，对于处于连接态的末端节点来说，还可通过中继节点获取gNB下发的更新后的系统信息。
具体实现方式可包括：
1)末端节点通过与gNB之间的RRC连接获取gNB下发的系统信息，中继节点透明传输系统信息；
2)末端节点获取中继节点通过与末端节点之间的连接发送来的系统信息，系统信息为gNB通过与中继节点之间的RRC连接发送给中继节点的；
3)末端节点通过中继节点的中继获取gNB下发的寻呼消息，并通过中继节点的中继获取gNB广播的系统信息，根据寻呼消息从系统信息中读取相应的系统信息块。
对于方式3)，需要增强paging机制，将gNB的寻呼消息中继给末端节点，也将系统信息中继给末端节点，这种方式要求末端节点的paging occasion和DRX cycle的配置不受中继及其所引入的延迟的影响。
基于上述介绍，图4为本发明所述末端节点、中继节点以及gNB之间的交互方式示意图。
如图4所示，假设中继节点共服务两个末端节点，两个末端节点均处于空闲态。
中继节点接收gNB广播的MSI，可进行透明转发，通过与末端节点之间的连接将MSI传输给末端节点。
末端节点确定自身是否有按需系统信息需求，如果有，则将按需系统信息需求发送给中继节点。
中继节点对获取到的各末端节点的按需系统信息需求进行汇总，根据汇总结果，向gNB发送按需系统信息请求。
gNB将所请求的按需系统信息通过中继节点下发给末端节点。
在上述各实施例中，对各实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其它实施例中的相关描述。
总之，采用上述各方法实施例所述方案，中继节点可获取基站广播的MSI，将MSI转发给所服务的末端节点，并可获取末端节点的按需系统信息需求，向基站请求末端节点所需的按需系统信息，进而将基站下发的按需系统信息发送给对应的末端节点，另外，中继节点还可将基站下发的更新后的系统信息发送给末端节点等，从而解决了中继场景下的系统信息的发送问题。
