5G系统中,考虑到终端功耗等问题,部分系统信息块可以基于终端的请求来发送(on-demand basis)。简单来说,系统信息由多个SIB(或者叫SI message)组成。MIB(主系统信息)在固定的位置和周期进行调度,MIB中含有SIB1等关键SIB的调度信息。SIB1中含有其它所有SIB的调度信息。In the 5G system, in consideration of problems such as terminal power consumption, some system information blocks can be transmitted on an on-demand basis based on the request of the terminal. In simple terms, system information consists of multiple SIBs (or SI messages). The MIB (Master System Information) is scheduled at a fixed location and period, and the MIB contains scheduling information of key SIBs such as SIB1. SIB1 contains scheduling information for all other SIBs.
5G为了支持系统信息按需发送,SIB1中为每个支持订阅的SIB设置了一个bit位,0表示该SIB在下个调度周期内不被调度,1表示该SIB在下个周期会被调度。因此,对应多个支持订阅SIB,会有多个bit指示这些SIB是否会被调度。基于UE的请求,网络开始调度某个支持订阅的SIB,网络则应同时修改SIB1的内容,将该SIB对应的调度信息的bit位置为1。同样,同时调度多个SIB,要将所调度的SIB的调度信息的bit位全置为1。In order to support the system information to be sent on demand, 5G sets a bit for each SIB that supports subscription, and 0 indicates that the SIB is not scheduled in the next scheduling period, and 1 indicates that the SIB will be scheduled in the next cycle. Therefore, corresponding to multiple support subscription SIBs, there will be multiple bits indicating whether these SIBs will be scheduled. Based on the request of the UE, the network starts to schedule a certain SIB that supports the subscription, and the network should modify the content of the SIB1 at the same time, and the bit position of the scheduling information corresponding to the SIB is 1. Similarly, when scheduling multiple SIBs at the same time, the bit bits of the scheduling information of the scheduled SIBs are all set to 1.
LTE系统中,系统信息完全由基站进行广播,系统信息修改时会通过寻呼消息通知终端进行系统信息更新;而5G系统中并没有限定在CU和DU分离的方案中如何实现网络侧与终端侧的系统信息的传递。In the LTE system, the system information is completely broadcast by the base station. When the system information is modified, the terminal is notified by the paging message to update the system information. The 5G system does not limit how the network side and the terminal side are implemented in the CU and DU separation scheme. The transfer of system information.

For the purpose of more clearly describing the method for transmitting the system information provided by the present disclosure, the following is exemplified.
第一例(UE在Msg.或者Msg.3中请求系统信息,CU根据请求准备系统信息)。The first example (the UE requests system information in Msg. or Msg.3, and the CU prepares system information according to the request).
DU收到Msg.1或者Msg.3中的系统信息请求,DU将UE请求的信息通 过F1-AP消息通知CU,比如:通知CU SIB 18被请求,无需提供UE ID信息;CU根据DU的请求,准备相应的SIB18以及SIB18的调度信息,并将之通过F1-AP发给相应的DU;DU根据调度信息把SIB18在广播信道上播报。The DU receives the system information request in Msg.1 or Msg.3, and the DU notifies the CU of the information requested by the UE through the F1-AP message, for example, notifying that the CU SIB 18 is requested, and does not need to provide the UE ID information; the CU according to the request of the DU The scheduling information of the corresponding SIB 18 and the SIB 18 is prepared and sent to the corresponding DU through the F1-AP; the DU broadcasts the SIB 18 on the broadcast channel according to the scheduling information.
第二例(UE在Msg.1或者Msg.3中请求系统信息,CU提前将全套系统信息发给了DU)。The second example (the UE requests system information in Msg.1 or Msg.3, and the CU sends the complete system information to the DU in advance).
假设5G系统中共支持3个订阅SI,设为SIB7、SIB8、SIB9;其调度信息均在SIB1中;而UE的订阅请求为SI B7,SIB8;以及It is assumed that 3 subscription SIs are supported in the 5G system, and are set to SIB7, SIB8, and SIB9; the scheduling information is in SIB1; and the subscription request of the UE is SI B7, SIB8;

The full set of SI includes SIB 7, SIB8, SIB9, and 8 sets of SIB1 that support subscription (the scheduling indication information in 8 sets of SIB1 respectively represents SIB 7) For the scheduling situation of SIB8 and SIB9, the scheduling information is “000” when there is no UE subscription, “111” when all requests are subscribed, and so on by others. The DU broadcasts all non-subscribed SIs according to the scheduling information; and selects SIB1 with scheduling information of 000 for transmission. The DU receives the SI request in the Msg.1 or the Msg.3 of the UE, and requests the SIB7 and the SIB8. The DU broadcasts the stored subscription SIB7 and SIB8 according to the request of the UE, and simultaneously broadcasts the SIB1 with the scheduling indication information of 110. Where "110" indicates that the terminal requests to subscribe to SIB7 and SIB8 without requesting to subscribe to SIB9.
第三例(UE在RRC消息中请求系统信息,CU根据请求准备系统信息)。The third example (the UE requests system information in an RRC message, and the CU prepares system information according to the request).

第四例(UE在RRC消息中请求系统信息,全套系统信息已经保存在DU,CU指示DU发送系统信息)。The fourth example (the UE requests system information in the RRC message, the complete system information has been saved in the DU, and the CU instructs the DU to send the system information).
DU收到来自UE的RRC消息,如:RRC Connection Request或RRC SI request消息,DU将RRC消息通过F1-AP将RRC消息传递的过程传递给CU;CU解析RRC消息,得知UE请求SIB18,CU给相应的DU发送F1-AP消息,指示其广播某SIB18;DU根据之前存储的SIB18的信息和对应的调度信息,将UE请求的SIB18在广播信道上播报。The DU receives an RRC message from the UE, such as an RRC Connection Request or an RRC SI request message, and the DU transmits the RRC message to the CU through the F1-AP. The CU parses the RRC message, and learns that the UE requests the SIB18, the CU.
