Technical field

The present disclosure relates to the field of communications technologies, and in particular, to a method and apparatus for transmitting system information.

Background technique

In an LTE (Long Term Evolution) system, an access network (E-UTRAN) is composed of a plurality of base station eNodeBs, and an eNodeB (base station) and an EPC (Packet Core Network) are connected through an S1 interface, and an eNodeB (base station) passes an X2. Interface connection. In the fifth generation mobile communication 5G system, a central node (CU, Central Unit) is introduced into the access network for centralized control and scheduling, and the function of the radio resource control RRC and the function of the partial layer 2 are in the central node CU, the base station. Other functions are deployed on the distribution node (DU, Distribute Unit). The interface (NG) of the base station and the core network is suspended at the central node CU, and the interface (Xn) between the base stations is also suspended at the central node CU.

In the related art, the network side node is divided into a central node (CU, Central Unit) and a distributed node (DU, Distribute Unit); the user side node is a terminal; the interface between the central node CU and the distribution node DU is called an F1 interface.

Regarding the separation of the CU and the DU on the RAN side of the radio access network, the specific separation manner includes the mode 1 to the mode 8.

Mode 1: Radio Resource Control RRC in CU, Packet Data Convergence Protocol PDCP, Radio Link Control Protocol RLC, Media Access Control Protocol MAC and Physical Layer, Radio Frequency RF in DU.

Mode 2: RRC, PDCP in CU, RLC, MAC and physical layer, RF in DU.

Mode 3: RRC, PDCP, RLC high level in CU, RLC bottom layer, MAC and physical layer, RF in DU.

Mode 4: RRC, PDCP, RLC in CU, MAC and physical layer, RF in DU.

Mode 5: RRC, PDCP, RLC, MAC high level in CU, MAC bottom layer and physical layer, RF in DU.

Mode 8: RRC, PDCP, RLC, MAC and physical layer in CU, RF in DU.

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.

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.

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.

It should be noted that, for a system information block that does not support scheduling, the DU broadcasts all non-subscribed system information blocks according to the scheduling information in the scheduling block, where the scheduling indication information of the non-subscribed system information in each scheduling block is 0. , indicating that the current schedule does not schedule the system information block.

In summary, the foregoing embodiment of the present disclosure is described in detail for the case where the system information block for which the terminal requests the subscription is generated by the central node CU. For the purpose of more clearly describing the method for transmitting the system information provided by the present disclosure, the following is exemplified.

The first example (the UE requests system information in Msg. or Msg.3, and the CU prepares system information according to the request).

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.

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).

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;

In the initial preparation system information phase, the CU prepares a full set of SI and corresponding scheduling information and sends it to the DU. 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.

The third example (the UE requests system information in an RRC message, and the CU prepares system information according to the request).

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, and the CU parses the RRC message to learn that the UE requests the SIB 18. The CU prepares the scheduling information of the corresponding SIB 18 and the SIB 18 according to the request of the DU, and sends the scheduling information to the corresponding DU through the F1-AP; the DU broadcasts the SIB 18 on the broadcast channel according to the scheduling information.

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).

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.
