It is different from the traditional cellular system in which communication data is received or sent through the base station. The Internet of Vehicles system uses The terminal-to-terminal direct communication method has higher spectrum efficiency and lower transmission delay. Two transmission modes are defined in 3GPP: Mode A and Mode B.

Mode A: The transmission resources of the terminal 120 are allocated by the base station 140 through the downlink, and the terminal 120 transmits data on the side link according to the transmission resources allocated by the base station 140; the base station 140 can allocate a single transmission for the terminal 120 Transmission resources can also be allocated to the terminal 120 for semi-static transmission transmission resources, as shown in FIG. 1.

Mode B: The terminal 120 selects a resource in the resource pool for data transmission. Specifically, the terminal 120 may select transmission resources from the resource pool by means of listening, or select transmission resources from the resource pool by means of random selection.

Fig. 2 shows a flowchart of a method for receiving system information provided by an exemplary embodiment of the present application. In this application, the method is applied to a terminal as an example. The terminal may be a terminal in a car networking system. The method includes:

Step 201: Receive broadcast information in a side-line broadcast channel;

The broadcast information is sent by other terminals. The broadcast information carries system information, which is synchronized by other terminals from a synchronization source. The synchronization source is eNB or gNB.

Among them, the eNB is the access network equipment in the Long-Term Evolution (LTE), and the gNB is the access network equipment in the NR system.

Step 202: Obtain instruction information;

Optionally, the indication information is explicitly carried or implicitly carried by the broadcast information. The indication information is used to indicate the type of system information carried in the broadcast information.

Exemplarily, the indication information is used to indicate that the system information carried in the broadcast information is the first parameter set; or, the indication information is used to indicate that the system information carried in the broadcast information is the second parameter set.

The first parameter set is a parameter set included in the system information provided by the eNB, and the second parameter set is a parameter set included in the system information provided by the NR.

Step 203: Determine the system information carried in the broadcast information according to the instruction information.

The terminal determines, according to the indication information, that the system information carried in the broadcast information is the first parameter set or the second parameter set.

The first parameter set is the system information corresponding to the first type of base station (eNB), and the first parameter set includes: system bandwidth, TDD-UL-DL configuration, direct frame number (DFN), subframe number, At least one item in the area indication information (In coverage indicator);

The second parameter set is system information corresponding to the second type of base station (gNB), and the second parameter set includes: BandWidth Part (BWP) indication information, TDD configuration indication information, DFN, slot number, intra-cell indication At least one item of information (In coverage indicator).

In summary, the method provided in this embodiment determines the system information carried in the broadcast information through the indication information, so that regardless of whether the system information comes from the eNB or gNB, the terminals outside the cell can correctly receive and parse the system information. Furthermore, interference caused by data transmission on downlink subframes by terminals outside the cell is avoided, and the communication quality of the Internet of Vehicles system is improved.

Fig. 3 shows a flowchart of a method for receiving system information provided by an exemplary embodiment of the present application. In this application, the method is applied to a terminal as an example. The terminal may be a terminal in a car networking system. The method includes:

Step 301: Generate broadcast information according to system information;

The terminal obtains the system information synchronously from the synchronization source. The synchronization source is eNB or gNB.

Among them, the TDD-UL-DL configuration is used to determine the information of the time slot or subframe.

The TDD configuration indication information is different from the TDD-UL-DL configuration information in the LTE system. In the LTE system, there are only 7 configurations of TDD-UL-DL, but in the gNB system, considering that it supports flexible time slot configuration, this information can indicate more configuration information. For example, the TDD configuration indication information is used to indicate The cell-specific slot format configuration information is either used to indicate time domain resource information that can be used for side-line transmission, or used to indicate uplink time slot or uplink time domain symbol information, etc.

Bandwidth part information: In the LTE system, the PSBCH includes information used to indicate the system bandwidth. For the gNB system, the bandwidth part is introduced. Therefore, the PSBCH needs to indicate the bandwidth part information.

Step 302: Send the broadcast information in the side-line broadcast channel, and the indication information carried in the broadcast message is used for the receiving terminal to determine the system information carried in the broadcast information.

Fig. 4 is a flowchart of a method for receiving system information provided by an exemplary embodiment of the present application. In this application, the method is applied to a terminal as an example. The terminal may be a terminal in a car networking system. The method includes:

Step 401: The first terminal generates broadcast information according to the system information, and the broadcast information carries the target bit field and system information;

Step 402: The first terminal sends broadcast information in the side-line broadcast channel, and the indication information carried in the broadcast message is used for the receiving terminal to determine the system information carried in the broadcast information;

Step 403: The second terminal receives the broadcast information in the side broadcast channel;

Step 404: The second terminal obtains the target bit field in the broadcast information.

Step 405: When the target bit field is the first value, the second terminal determines that the system information carried in the broadcast information is the first parameter set;

The first parameter set is system information corresponding to the first type of base station (eNB). The first parameter set includes: system bandwidth, TDD-UL-DL configuration, DFN, subframe number, and cell indication information (Indicator) At least one of

Step 406: When the target bit field is the second value, the second terminal determines that the system information carried in the broadcast information is the second parameter set.

In summary, the method provided in this embodiment uses explicit indication information (target bit field) to determine the system information carried in the broadcast information, so that regardless of whether the system information comes from the eNB or gNB, the terminals outside the cell can be correct The system information is received and analyzed, thereby avoiding the interference caused by the terminal outside the cell transmitting data on the downlink subframe, and improving the communication quality of the car networking system.

Fig. 5 is a flowchart of a method for receiving system information provided by an exemplary embodiment of the present application. In this application, the method is applied to a terminal as an example. The terminal may be a terminal in a car networking system. The method includes:

Step 501: The first terminal generates broadcast information according to system information, and the broadcast information carries synchronization information blocks and system information;

The terminal generates broadcast information, and the broadcast information carries system information and a side-line synchronization signal block (SideLink SS/PBCH block, S-SSB). The indication information is the synchronization signal identification number indicated by the SideLink Primary Synchronization Signal (S-PSS) and the SideLink Secondary Synchronization Signal (S-SSS) in the SSB.

Exemplarily, the synchronization signal identification number belonging to the first set is used to indicate that the system information carried in the broadcast information is the first parameter set; or the synchronization signal identification number with the second set is used to indicate that the system information carried in the broadcast information The system information is the second parameter set.

In an example, the first set is: {0,1,...,167}, and the second set is: {168,169,...,335}.

In another example, the first set is: {1,...,167}; the second set is: {170,171,...,335}. This is because in LTE-V2X, when the synchronization source of the terminal comes from the Global Navigation Satellite System (GNSS), the SSID corresponding to the SLSS sent by it is 0. If the synchronization source of the terminal comes from the direct For GNSS-synchronized terminals, the SSID corresponding to the SLSS sent by it is 168 or 169. Therefore, considering that SSIDs 168 and 169 will also be used by LTE-V2X, these two SSIDs need to be excluded from the second subset.

Step 502: The first terminal sends broadcast information in the side-line broadcast channel, and the indication information carried in the broadcast message is used for the receiving terminal to determine the system information carried in the broadcast information;

Step 503: The second terminal receives the broadcast information in the side-line broadcast channel;

Step 504: The second terminal obtains the side-line primary synchronization signal and the side-line secondary synchronization signal from the synchronization signal block where the broadcast information is located;

Step 505: The second terminal determines the synchronization signal identification number according to the side-line primary synchronization signal and the side-line secondary synchronization signal;

Exemplarily, the second terminal determines the synchronization signal identification number according to the following formula:

among them,

Is obtained through the side-line auxiliary synchronization signal,

It is obtained through the main synchronization signal of the side row.

Step 506: When the synchronization signal identification number belongs to the first set, the second terminal determines that the system information carried in the broadcast information is the first parameter set;

Among them, the first set is: {0,1,...,167} or {1,...,167}.

Step 507: When the synchronization signal identification number belongs to the second set, the second terminal determines that the system information carried in the broadcast information is the second parameter set.

Among them, the second set is: {168,169,...,335} or {170,171,...,335}.

In summary, the method provided in this embodiment uses implicit indication information (synchronization signal identification number) to determine the system information carried in the broadcast information, so that regardless of whether the system information comes from an eNB or a gNB, terminals outside the cell can be Correctly receive and analyze the system information, thereby avoiding the interference caused by the terminal outside the cell transmitting data on the downlink subframe, and improving the communication quality of the car networking system.

In a possible implementation based on Figure 2, the terminal receives a side-line synchronization signal (Sidelink Synchronization Signal, SLSS), and the side-line synchronization signal includes a side-line primary synchronization signal (Sidelink Primary Synchronization signal, S-PSS) and a side-line secondary synchronization signal. For a synchronization signal (Sidelink Secondary Synchronization signal, S-SSS), the terminal determines whether the system information carried in the broadcast information is the first parameter set or the second parameter set according to the time domain positions of the S-PSS and the S-SSS. For example, if the time-domain symbols for sending S-PSS and S-SSS are adjacent or differ by one time slot, it can be determined that the system information carried in the broadcast information is the second parameter set, that is, the system information provided by gNB ; If the time-domain symbols for sending S-PSS and S-SSS differ by more than one time-domain symbol, it can be determined that the system information carried in the broadcast information is the first parameter set, that is, the system information provided by the eNB.
