In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

In order to facilitate the understanding of the technical solutions of the embodiments of the present invention, Mode 3 and Mode 4 in the Internet of Vehicles are explained below respectively.

Mode 3: As shown in Figure 1, the transmission resources of the vehicle terminal are allocated by the base station (such as the evolved node (eNB, evolved NodeB) in LTE or the 5G node gNB in the new wireless (NR, New Radio) system), Specifically, the base station sends a control message for indicating Grant resources to the vehicle terminal through a downlink (DL, Down Link); then, the vehicle terminal sends data on the SL according to the resources allocated by the base station. In mode 3, the base station can allocate resources for a single transmission to the vehicle-mounted terminal, and can also allocate resources for semi-static transmission to the terminal.

Mode 4: As shown in Figure 2, the vehicle-mounted terminal adopts the transmission mode of listening + reservation. The vehicle-mounted terminal acquires a set of available transmission resources through listening in the resource pool, and the vehicle-mounted terminal randomly selects a resource from the transmission resource set for data transmission. Because the business in the Internet of Vehicles system has periodic characteristics, the vehicle-mounted terminal usually adopts a semi-static transmission method, that is, after the vehicle-mounted terminal selects a transmission resource, it will continue to use the resource in multiple transmission cycles, thereby reducing resource weight. selection and the probability of resource conflicts. The vehicle-mounted terminal will carry the message of reserving the next transmission resource in the control message of this transmission, so that other terminals can judge whether this resource is reserved and used by the vehicle-mounted terminal by detecting the control message of the vehicle-mounted terminal, so as to reduce The purpose of resource conflicts.

It should be noted that in LTE-V2X, mode 3 is used to indicate that the transmission resources of the vehicle terminal are allocated by the base station, and mode 4 is used to indicate that the transmission resources of the vehicle terminal are independently selected by the terminal. In the new wireless-vehicle networking technology ( In NR-V2X, New Radio-Vehicle-to-Everything), a new transmission mode can be defined, which is not limited in the present invention.

For the mode architecture of the Internet of Vehicles mentioned above, when the terminal performs synchronous transmission on multiple carriers, the high-end equipment in the network usually configures the first carrier set, which includes carriers capable of providing synchronization reference information, and the terminal can use it from The second carrier set is selected from the first carrier set, and the second carrier set includes carriers for multi-carrier synchronous transmission by the terminal. Therefore, the second carrier set can be considered as a subset of the first carrier set, or even the second carrier set The set of carriers may be the same as the first set of carriers. Based on the above relationship between the two carrier sets, it is necessary to configure the first carrier set for the terminal, which is also the effect to be achieved by the technical solution of the embodiment of the present invention.

All the technical solutions of the embodiments of the present invention are not only applicable to the Internet of Vehicles system, but also applicable to other end-to-end communication systems. The terminals in the embodiments of the present invention can be vehicle-mounted terminals, handheld terminals, palmtop computers (PDAs) , Personal Digital Assistant), a wearable terminal, etc., the network in the embodiment of the present invention may be an NR network, an LTE network, and the like.

Referring to FIG. 3, it shows a flow of a method for configuring a synchronous carrier provided by an embodiment of the present invention. This flow can be applied to a terminal in a V2X architecture of the Internet of Vehicles. The method can include:

S301: Acquire a first carrier set based on configuration information; wherein, the first carrier set includes at least one candidate carrier;

S302: Select a synchronization carrier from candidate carriers in the first carrier set.

In the solution shown in Figure 3, it should be noted that the synchronization carrier refers to a carrier capable of carrying synchronization messages, and the synchronization messages can be GNSS-based time synchronization messages and/or frequency synchronization messages; they can also be time synchronization messages based on base stations. A synchronization message and/or a frequency synchronization message; it may also be a terminal-based time synchronization message and/or a frequency synchronization message. The solution shown in FIG. 3 will not be described in detail. The above synchronization information can be used to provide time synchronization information and/or frequency synchronization information for other carriers during multi-carrier transmission, so as to realize synchronous data transmission by multiple carriers.

For the technical solution shown in Figure 3, in a possible implementation manner, the acquiring the first carrier set based on the configuration message includes:

receiving a configuration message sent by the network side device; wherein, the configuration message includes all carriers that the sidelink system can support;

Parsing the configuration message, acquiring all carriers that the sidelink system can support from the configuration message, and using all the carriers as the first set of carriers.

With regard to this implementation method, it should be noted that the network side device may send configuration messages through broadcast messages, RRC-related signals, or control channels. Correspondingly, receiving the configuration message sent by the network-side device may specifically include: receiving a broadcast message, an RRC-related signal or a control channel that carries the configuration message sent by the network-side device.

For example, the network-side device takes a base station as an example. The base station can be preferably an eNB or a gNB. When the terminal is only within the coverage of the base station but does not access the base station, the base station can only pass through The message is transmitted to the terminals in the coverage area by means of broadcasting. Therefore, the base station can carry the configuration message in the broadcast message and transmit it to the terminal. In addition, when the terminal accesses the base station and establishes an RRC connection, the base station can also carry configuration information in an RRC interaction signal and send it to the terminal. After the terminal access is completed, the above configuration information can be transmitted through the control channel.

In addition, the configuration information may also be pre-configured or pre-stored in the terminal. Based on this, in another possible implementation manner, the acquiring the first carrier set based on the configuration information includes: obtaining the first set of carriers by parsing the pre-configured configuration information. All the carriers that the sidelink system can support, and use all the carriers as the first set of carriers.

For the above two implementations, selecting a synchronization carrier from the candidate carriers in the first carrier set includes:

selecting a second set of carriers for multi-carrier transmission from all carriers capable of being supported by the sidelink system;

Select the synchronization carrier from the second set of carriers.

It should be noted that at a certain moment, the terminal does not use all the carriers that the sidelink system can support for multi-carrier transmission. Therefore, when the base station sends all the carriers that the sidelink system can support to the terminal, The terminal can determine the carrier used for multi-carrier transmission from all the carriers, and the number of the carrier is usually at least one, so a second carrier set is formed. It can be understood that the second set of carriers is a subset of the first set of carriers, that is to say, the carriers in the second set of carriers must also be in the first set of carriers. Therefore, when the terminal can use the In the case that all supported carriers perform multi-carrier transmission, the second set of carriers is the same as the first set of carriers.

Moreover, since all the carriers in the second carrier set can perform multi-carrier data transmission, the terminal can select a synchronization carrier from them according to a set selection strategy, for example, select a synchronization carrier from the second carrier set according to the priority order, such as , the carrier with a higher priority in the second carrier set is used as the synchronization carrier; understandably, the specific priority determination method can be based on the priority of the synchronization reference message in the carrier; or the priority of the carrier itself, such as the priority of the main carrier The order is higher than that of the secondary carrier, etc.; or based on the priority order of the service corresponding to each carrier, which will not be described in this embodiment.

Taking the schematic diagram of the carrier set shown in Figure 4 as an example, for example, the maximum number of carriers that the network system can support is 8, which are respectively identified as carrier 1, carrier 2, carrier 3,..., carrier 8; then the A high-end device, such as a base station, can use the above-mentioned set of 8 carriers as the first set of carriers, and send the set of carriers to the terminal through a configuration message, and the terminal can select the first set of carriers in the configuration message. The second carrier set for multi-carrier transmission, for example, the second carrier set includes carrier 1 and carrier 2, and then the terminal can select a synchronization carrier for synchronization reference from the second carrier set according to the priority order, for example, Is carrier 1, or, carrier 2, or, when the two carriers have the same priority order, the synchronous carriers are carrier 1 and carrier 2.

For the technical solution shown in Figure 3, in a possible implementation manner, the acquiring the first carrier set based on the configuration message includes:

receiving a configuration message sent by the network side device; wherein, the configuration message includes a carrier that can be used by a terminal conforming to a preset capability description;

parsing the configuration message, obtaining from the configuration message the carrier that the terminal conforming to the preset capability description can use, and using the carrier that the terminal conforming to the preset capability description can use as the first carrier gather.

With regard to this implementation, it should be noted that the network side device can still send configuration messages through broadcast messages, RRC-related signals, or control channels. For the specific sending process, refer to the aforementioned implementation manners, which will not be repeated here.

In addition, the configuration information may also be pre-configured or pre-stored in the terminal. Based on this, in another possible implementation manner, the acquiring the first carrier set based on the configuration information includes:

Obtain the carriers available to the terminal meeting the preset capability description by parsing the pre-configured configuration message, and use the carriers available to the terminal meeting the preset capability description as the first set of carriers.

For the above two implementations, selecting a synchronization carrier from the candidate carriers in the first carrier set includes:

Selecting a second set of carriers used for multi-carrier transmission from the carriers that can be used by the terminal conforming to the preset capability description;

Select the synchronization carrier from the second set of carriers.

For the above two implementation methods, in the specific implementation process, since the capabilities of each terminal in the same network are different, in order to realize multi-carrier transmission between terminals with different capabilities, it is necessary to use different terminals Carriers that can be used by all, usually use carriers that can be used by terminals with lower capabilities. For example, in the D2D architecture or V2X architecture, some terminals can support the 3GPP standard version Rel-14 or earlier versions, and some terminals can support the 3GPP standard version Rel-15; therefore, the terminals that support the Rel-15 version will support the Rel- When a terminal of version 14 or earlier performs multi-carrier transmission, it needs to use a carrier that can be used by a terminal that supports version 14 or earlier. Therefore, the carrier that can be used by a terminal that meets the preset capability description includes: Carriers that can be used by terminals that support end-to-end communication technologies in 3GPP Release 14 and earlier.

Taking the schematic diagram of carrier set shown in FIG. 5 as an example, for example, the maximum number of carriers supported by the network system is 8, which are respectively identified as carrier 1, carrier 2, carrier 3, ..., carrier 8. The carriers that can be used by terminals supporting the 3GPP protocol Rel-14 version are used as the first carrier set. For example, carrier 1, carrier 2, carrier 3, and carrier 4 are carriers that can be used by Rel-14 terminals, then the first carrier set Including Carrier 1, Carrier 2, Carrier 3, and Carrier 4. Assuming that the terminal in this embodiment supports the 3GPP protocol Rel-15 version, then the terminal can combine the carriers required for multi-carrier transmission, such as carrier 1, carrier 2 and carrier 5, after receiving the first set of carriers through the configuration message. The terminal can detect the synchronization messages on the carrier 1 and the carrier 2 in turn, so as to divide the carrier 1 and the carrier 2 into a second set of carriers, and select a synchronization carrier therefrom.

Based on the same inventive concept as the foregoing technical solution, see FIG. 6 , which shows a flow of a method for configuring a synchronous carrier provided by an embodiment of the present invention. This flow can be applied to network-side devices in the V2X architecture of the Internet of Vehicles. The method can include :

S601: Send a configuration message to the terminal; wherein, the configuration message includes a first set of carriers; the first set of carriers is used for the terminal to select a synchronization carrier.

For the technical solution shown in FIG. 6 , the configuration message may include all carriers that the sidelink system can support, or the carriers that can be used by the terminal conforming to the preset capability description.

For the technical solution shown in Figure 6, in a possible implementation manner, sending the configuration message to the terminal may include:

Sending a configuration message to the terminal through a broadcast message, an RRC-related signal or a control channel.

It can be understood that, for the specific content of this implementation manner, refer to the technical solution shown in FIG. 3 , which will not be repeated here.

Based on the configuration message including the carrier that can be used by the terminal conforming to the preset capability description, in a possible implementation manner, the method further includes:

Based on the set capability description information, select the carrier that can be used by the terminal conforming to the preset capability description from all the carriers that the sidelink system can support.

For example, a network-side device, such as a base station, can obtain the capability description information of terminals in the communication coverage of the base station during the attachment or access process of these terminals, and in order to achieve multi-carrier transmission between terminals with different capabilities , the network side equipment, such as the base station, can select the carrier that can be used by the terminal conforming to the preset capability description from all the carriers that can be supported by the sidelink system. Generally speaking, the carriers that can be used by a terminal conforming to the preset capability description refer to the carriers that can be used by a terminal with a lower capability. Preferably, in the specific implementation process of this embodiment, the carriers that can be used by the terminals conforming to the preset capability description include the carriers that can be used by terminals that support the end-to-end communication technology in 3GPP version 14 and earlier versions. Therefore, the terminal supporting 3GPP release 15 and the terminal supporting 3GPP release 14 and earlier versions can perform multi-carrier transmission.
