Detailed ways

The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

To facilitate understanding of the technical solutions of the embodiments of the present invention, modes 3 and 4 in the Internet of Vehicles are separately explained below.

Mode 3: As shown in FIG. 1 , the transmission resource of the in-vehicle terminal is allocated by a base station (such as an evolved NodeB in LTE or a 5G base station gNB in a new radio (NR, New Radio) system, specifically The base station sends a control message for indicating the Grant resource to the in-vehicle terminal through the downlink (DL, Down Link). Then, the in-vehicle terminal transmits the data on the SL according to the resource allocated by the base station. In mode 3, the base station may allocate a single transmission resource for the vehicle terminal, or may allocate a semi-static transmission resource for the terminal.

Mode 4: As shown in Figure 2, the vehicle terminal adopts a transmission mode of listening and reservation. The vehicle terminal acquires an available transmission resource set by means of interception in the resource pool, and the vehicle terminal randomly selects one resource from the transmission resource set for data transmission. Since the service in the car network system has periodic characteristics, the vehicle terminal usually adopts a semi-static transmission mode, that is, after the vehicle terminal selects one transmission resource, the resource is continuously used in multiple transmission cycles, thereby reducing the resource weight. The probability of selection and resource conflicts. The vehicle terminal carries information for reserving the next transmission resource in the control information of the current transmission, so that other terminals can determine whether the resource is reserved and used by the vehicle terminal by detecting the control information of the vehicle terminal. The purpose of resource conflicts.

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

For the above-mentioned mode architecture of the Internet of Vehicles, when the terminal performs synchronous transmission on multiple carriers, the first carrier set is usually configured by the high-level device in the network, and the set includes a carrier having the capability of providing synchronization reference information, and the terminal can The second carrier set is selected from a set of carriers, and the second carrier set includes a carrier for performing multi-carrier synchronous transmission by the terminal. Therefore, the second carrier set may be regarded as a subset of the first carrier set, or even the second carrier. The set can be the same as the first set of carriers. Based on the relationship between the two sets of carriers, the first carrier set needs to be configured 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 applicable not only to the vehicle networking system, but also to other end-to-end communication systems. The terminal in the embodiment of the present invention may be an in-vehicle terminal, a handheld terminal, or a palmtop computer (PDA). The personal digital assistant, the wearable terminal, and the like, the network in the embodiment of the present invention may be an NR network, an LTE network, or the like.

Referring to FIG. 3, it is a flowchart of a method for configuring a synchronization carrier according to an embodiment of the present invention. The process may be applied to a terminal in a V2X architecture of a vehicle network, and the method may include:

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

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

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

For the technical solution shown in FIG. 3, in a possible implementation, the acquiring the first carrier set based on the configuration information includes:

Receiving configuration information sent by the network side device, where the configuration information includes all carriers that the side-link system can support;

Parsing the configuration information, acquiring all carriers that the side-link system can support from the configuration information, and using the all carriers as the first carrier set.

For the implementation manner, it should be noted that the network side device may send the configuration information by using a broadcast message, an RRC related signaling, or a control channel. Correspondingly, the receiving the configuration information sent by the network side device may include: receiving a broadcast message, an RRC related signaling, or a control channel that is sent by the network side device and carrying the configuration information.

For example, the network side device takes a base station as an example. The base station may preferably be an eNB or a gNB. When the terminal is only in the coverage of the base station but does not access the base station, the base station can only be in the broadcast mode. The terminal within the coverage transmits the message, and therefore, the base station can carry the configuration information in the broadcast message to the terminal for transmission. In addition, in the process of the terminal accessing the base station and establishing the RRC connection, the base station may also send the configuration information to the terminal in the RRC interaction signaling. After the terminal access is completed, the above configuration information can be transmitted through the control channel.

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

For the foregoing two implementation manners, selecting a synchronization carrier from the candidate carriers of the first carrier set includes:

Selecting a second carrier set for performing multi-carrier transmission from all carriers that the side-link system can support;

Selecting the synchronization carrier from the second set of carriers.

It should be noted that, at a certain moment, the terminal does not use the carrier that can be supported by the side-link system to perform multi-carrier transmission. Therefore, when the base station sends all the carriers that the side-link system can support to the terminal, the terminal The carrier for multi-carrier transmission can be determined from all the carriers, and the number of the carriers is usually at least one, so a second carrier set is formed. It can be understood that the second carrier set is a subset of the first carrier set, that is, the carriers in the second carrier set are also necessarily in the first carrier set, and therefore, when the terminal can use the side-link system, In the case where all supported carriers perform multi-carrier transmission, the second carrier set and the first carrier set are the same.

Moreover, since the carriers in the second carrier set are capable of multi-carrier data transmission, the terminal may select the synchronization carrier according to the set selection policy, for example, select the synchronization carrier from the second carrier set according to the priority level. For example, a carrier with a higher priority in the second carrier set is used as the synchronization carrier; it can be understood that the specific priority determination manner may be based on the priority of the synchronization reference information in the carrier; or the priority of the carrier itself, such as the primary carrier. The priority is higher than that of the carrier or the like; or the priority of the service corresponding to each carrier is not described in this embodiment.

Taking the carrier set diagram shown in FIG. 4 as an example, for example, the maximum number of carriers that the network system can support is eight, which are respectively identified as carrier 1, carrier 2, carrier 3, ..., carrier 8; then the high-level device in the network For example, the base station may use the set of the foregoing 8 carriers as the first carrier set, and send the carrier set to the terminal through the configuration information, and the terminal may select, in the first carrier set in the configuration information, The second carrier set of the carrier transmission, for example, the second carrier set includes carrier 1 and carrier 2. Then, the terminal may select a synchronization carrier for synchronization reference from the second carrier set according to the priority level, for example, it may be carrier 1 Or, carrier 2, or when the two carriers have the same priority, the synchronization carrier is carrier 1 and carrier 2.

Receiving configuration information sent by the network side device, where the configuration information includes a carrier that can be used by the terminal that meets the preset capability description;

Parsing the configuration information, obtaining, from the configuration information, a carrier that can be used by the terminal that meets the preset capability description, and using a carrier that can be used by the terminal that meets the preset capability description as the first carrier set.

For the implementation, it should be noted that the network side device can still send the configuration information by using a broadcast message, an RRC related signaling, or a control channel. For the specific sending process, refer to the foregoing implementation manner, and details are not described herein again.

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

The carrier that can be used by the terminal that meets the preset capability description is obtained by parsing the pre-configured configuration information, and the carrier that can be used by the terminal that meets the preset capability description is used as the first carrier set.

Selecting, from the carriers that can be used by the terminal that meets the preset capability description, a second carrier set for performing multi-carrier transmission;

Selecting the synchronization carrier from the second set of carriers.

For the above two implementation manners, in the specific implementation process, since the capabilities of the terminals in the same network are different, if multi-carrier transmission is implemented between the terminals with different capabilities, then it is necessary to adopt different terminals. Carriers that can be used usually use carriers that can be used by lower-capability terminals. For example, in the D2D architecture or the V2X architecture, some terminals can support the 3GPP standard version Rel-14 or the previous version, and some terminals can support the 3GPP standard version Rel-15; therefore, the terminal supporting the Rel-15 version is supporting the Rel- When the terminal of the version 14 or the previous version performs the multi-carrier transmission, the carrier that can be used by the terminal supporting the Rel-14 version or the previous version is required. Therefore, the carrier that can be used by the terminal that meets the preset capability description includes: Carriers that can be used by terminals supporting end-to-end communication technology in 3GPP Release 14 and earlier.

Taking the carrier set diagram shown in FIG. 5 as an example, for example, the maximum number of carriers that the network system can support is eight, which are respectively identified as carrier 1, carrier 2, carrier 3, ..., carrier 8. Supporting a carrier that can be used by a terminal of the 3GPP protocol Rel-14 version as a first carrier set, for example, carrier 1, carrier 2, carrier 3, and carrier 4 are carriers that can be used by the Rel-14 terminal, then the first carrier set Including carrier 1, carrier 2, carrier 3, carrier 4. In the embodiment, the terminal supports the 3GPP protocol Rel-15 version, and the terminal can combine the carrier required for multi-carrier transmission after receiving the first carrier set by using the configuration information, for example, carrier 1, carrier 2, and carrier 5. . The terminal can sequentially detect the synchronization information on carrier 1 and carrier 2, thereby dividing carrier 1 and carrier 2 into a second carrier set, and selecting a synchronization carrier therefrom.

Based on the same inventive concept of the foregoing technical solution, referring to FIG. 6 , a flow of a method for configuring a synchronous carrier according to an embodiment of the present invention is shown, which may be applied to a network side device in a V2X architecture of a vehicle network, and the method may be include:

S601: Send configuration information to the terminal, where the configuration information includes a first carrier set, and the first carrier set is used by the terminal to select a synchronization carrier.

For the technical solution shown in FIG. 6, the configuration information may include all carriers that the side-link system can support, or a carrier that can be used by the terminal that conforms to the preset capability description.

For the technical solution shown in FIG. 6, in a possible implementation manner, sending configuration information to the terminal may include:

The configuration information is sent to the terminal through a broadcast message, an RRC related signaling, or a control channel.

For details, refer to the technical solution shown in FIG. 3 for details of the implementation, and details are not described herein again.

The method further includes: based on the configuration information, the carrier that is used by the terminal that meets the preset capability description, where the method further includes:

And selecting, according to the set capability description information, a carrier that can be used by the terminal that meets the preset capability description from all carriers that can be supported by the side-link system.

For example, a network side device, for example, a base station, may acquire capability description information of the terminals in a process of attaching or accessing a terminal in the communication coverage of the base station, and in order to implement multi-carrier transmission between terminals of different capabilities, the network The side device, for example, the base station, can select a carrier that can be used by the terminal that meets the preset capability description from all the carriers that the sidelink system can support. In general, a carrier that can be used by a terminal that conforms to a preset capability description refers to a carrier that can be used by a less capable terminal. Preferably, in the specific implementation process of the embodiment, the carrier that can be used by the terminal that meets the preset capability description includes a carrier that can be used by a terminal supporting end-to-end communication technology in 3GPP Release 14 and previous versions. Thereby, it is possible to enable a terminal supporting 3GPP Release 15 to perform multi-carrier transmission with a terminal supporting 3GPP Release 14 and earlier.

The terminal in the embodiment of the present invention selects a synchronization carrier from the candidate carriers of the configuration information, thereby implementing a setting scheme for the synchronization carrier when performing multi-carrier transmission in the vehicle networking technology.
