Detailed Description

For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail below with reference to the accompanying drawings, wherein it is apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The 5G NR system information includes a master information block (MIB, master Information Block) and a series of system information blocks (SIBs, system Information Block). The content included in the system information can be classified into a Minimum SI and a Other SI, in which:

the Minimum SI contains basic information of initial access and obtaining other system information, i.e. it mainly includes MIB and SIB1.

The MIB message contains cell barring status information and physical layer information necessary for acquiring further system messages, such as the configuration of CORESET # 0. MIB messages are carried on BCH channels and broadcast periodically.

The SIB1 message defines the scheduling of other system message blocks on the one hand and contains the messages required for initial access on the other hand. SIB1, also commonly referred to as RMSI (Remaining Minimum SI), is carried on the DL-SCH channel and may be broadcast periodically or in RRC CONNECTED state rrc_connected, the UE is informed through DL-SCH by dedicated signaling.

Other SI covers all system messages that are not broadcast at the Minimum SI, and these SIBs can be sent in several ways:

periodically broadcasting on the DL-SCH;

a UE in RRC IDLE rrc_idle or RRC INACTIVE state rrc_inactive state requests broadcasting;

In the rrc_connected state, it is transmitted to the UE on the DL-SCH channel in a dedicated manner.

The partial Other SI is listed below:

the SIB2 contains cell reselection information, and is mainly related to a serving cell;

SIB3 covers the frequency information of the service cell on one hand, and contains the same-frequency neighbor cell information of the cell reselection on the other hand, and mainly comprises the public frequency parameter of the cell reselection and the special parameter of the cell reselection;

SIB4 covers the message of other NR frequency on one hand, on the other hand, contains the different frequency adjacent cell information of the cell reselection, mainly include the public frequency parameter and specialized parameter of the cell reselection;

the SIB5 contains E-UTRA system frequency information and E-UTRA neighbor cell information of cell reselection, including common frequency parameters of cell reselection and special parameters of cell reselection;

SIB6 contains the main notification information of ETWS (Earthquake and Tsunami Warning System);

the SIB7 contains auxiliary passing information of the ETWS;

SIB8 contains a notification message of CMAS (Commercial Mobile Alert System);

SIB9 contains GPS time and UTC (Coordinated Universal Time) information.

Each cell of the existing 4G and 5G networks broadcasts own cell information for the UE to select the cell for residence and access, and broadcasts neighbor cell information of the cell for the UE to reselect the cell. The access under the mechanism depends on the access information of each cell, the UE firstly acquires the system information of the cell, selects the resident cell according to the configuration in the system information, and then initiates random access by using the random access resource in the system information of the cell. This limits that each cell must transmit system information and that the access of the terminal must be initiated to one cell based on the system information of each cell. Even if a plurality of cells are co-sited or overlapped, each cell also transmits system information, which is not beneficial to energy conservation and emission reduction.

In view of the above technical problems, embodiments of the present application provide an architecture diagram of a system to which a method for a terminal to access a combined system information network is applied.

Example 3 is also applicable to a case where an interface exists between DUs, where a DU where a cell not responsible for transmitting joint system information is located directly transmits cell information to a DU where a cell responsible for transmitting joint system information is located through an inter-DU interface, and the joint system information is generated from the DU.

Cells 1-4 are cells for transmitting joint system information, where Cell 1 transmits joint system information, cell2, cell3, cell4 only transmit synchronization signals, and no system information is transmitted, and as shown in fig. 7, mainly includes:

Step 0: the UE configures or pre-configures a frequency list of cell search, performs cell search on the frequency points, and selects cell1 meeting cell selection conditions for synchronization.

Step 1: cell1 sends joint system information, and UE receives the joint system information from Cell1 to acquire access configuration and synchronization signal information of cells 1-4.

Step 2 (2, 2a,2b,2 c): cells 1-4 periodically send Cell synchronization signals.

Step 3: the UE detects the synchronization signal and selects the cell, specifically detects or measures the cell in the corresponding resource according to the synchronization signal information of a plurality of cells in the combined system information, evaluates each cell based on the parameters in the combined system information and performs cell access sequencing according to the result, and the first sequencing of the cell2 is assumed.

Step 4: the UE initiates an access request on cell2 using the access configuration of cell2 in the joint system information.

Step 5: and the UE receives the access response of the cell2 according to the access response configuration of the cell2 in the joint system information.

Step 6: and establishing control plane and/or user plane connection between the UE and the cell 2.
