Description

Method and equipment for data transmission

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for data transmission.

Background

In the current D2D (Device-to-Device) communication field, the requirement for consistency of the terminals in communication is high, and there is a need for updating the transmission configuration information due to the characteristics of diverse services and geographical area correlation. However, each terminal may obtain the updated transmission configuration information at different time, so that the configurations used by the terminals are inconsistent, and if the transmission configuration information used by the sending terminal is different from that used by the receiving terminal, the receiving is directly failed.

In the prior art, the PC5 interface is a terminal-to-terminal direct communication interface introduced in the D2D project of 3GPP Rel (release) -12. The adjacent terminals can perform data transmission through a direct link in a short distance range without forwarding through a central node (namely a base station) or information transmission between the terminals through a traditional cellular link.

Taking V2X (vehicle-to-Everything) communication in the D2D communication field as an example, V2X communication mainly includes three contents: V2V (Vechile-to-Vechile, car-to-car): communication between On Board Units (OBUs) On the vehicle; V2I (vehicle-to-Infrastructure, lane network): communication between the vehicle and an RSU (Road side unit); V2P (vehicle-to-Pedestrian): communication between the vehicle and the pedestrian.

For direct communication of the PC5 port, a terminal needs to obtain transmission configuration information from an LTE-V2X (Long Term Evolution-vehicle-to-Everything) communication node, and since a V2X communication node may be located in a different LTE-V2X communication network and the V2X communication node has a fast moving speed, if interconnection and intercommunication among V2X communication nodes are realized, transmission configuration information of cooperative PC5 port communication needs to be configured.

When configuring transmission configuration information for different terminals, for example, configuring transmission configuration information for each terminal through LTE-V2X cloud, it cannot be guaranteed that all terminals are configured at the same time due to differences in time, location, and the like, so that different transmission configuration information currently used by terminals in the same area may occur.

In summary, if the configuration update between the terminals is not synchronous in the prior art, data transmission cannot be performed.

step 101, the terminal determines a configuration version for sending according to a matching result;

and 102, the terminal sends the transmission configuration information corresponding to the determined version.

The terminal carries out matching receiving through the transmission configuration information of the plurality of started versions, then determines the configuration version used for sending according to the matching result, and sends according to the transmission configuration information corresponding to the determined version.

The embodiment of the invention is suitable for all scenes which comprise a plurality of versions of transmission configuration information for transmission, such as V2X transmission.

In an implementation, different versions of the transport configuration information may be configured for each terminal by a configuration function entity (such as the V2X cloud).

The transmission configuration information includes, but is not limited to, one or more of the following:

version information such as a version of a current configuration, a version that can be used, and a part or all of a lowest version that can be used;

enable time, from which this version is used;

valid time information, after which time this version expires;

a list of authorized PLMNs (Public Land Mobile networks);

wireless parameter configuration information related to a geographic location;

service-related information including an authorized service, a service ID (Identification, code), and a correspondence between the service ID and an ID used by a transport layer;

a default transport Layer ID, namely a default destination Layer-2 ID;

the information related to privacy protection may include an original transport Layer ID (source Layer-2 ID) and an IP address that the terminal needs to change autonomous allocation after a period of time.

Optionally, before the terminal performs receiving and matching through the enabled transmission configuration information of multiple versions, after receiving the transmission configuration information of the new configuration, if the transmission configuration information of the new configuration does not include the enabling time, the transmission configuration information of the new configuration is used as the enabled transmission configuration information; or

After receiving the newly configured transmission configuration information, if the newly configured transmission configuration information includes the enabling time, the terminal takes the newly configured transmission configuration information as the enabled transmission configuration information after the enabling time is reached.

Specifically, the terminal determines whether the version of the transmission configuration information is enabled, and after receiving the transmission information of the new configuration, a main terminal determines whether the transmission configuration information of the new configuration includes enabling time, and if the transmission configuration information of the new configuration does not include the enabling time, the transmission configuration information of the new configuration is used as the enabled transmission configuration information to perform data receiving matching; if the transmission configuration information of the new configuration includes the activation time, the transmission configuration information of the new configuration is used as the activated transmission configuration information to perform data receiving matching after the activation time is reached, which is described below.

In a first mode, the terminal receives transmission information of a new configuration without starting time, and the transmission configuration information of the new configuration is used as the started transmission configuration information.

For example, the version information of the new configuration received by the terminal is V5, and V5 does not include the activation time, and at this time, the received transmission configuration information of the version V5 of the new configuration is used as the activated transmission configuration information to perform data reception matching.

And in the second mode, the transmission information of the new configuration received by the terminal comprises the starting time, and after the starting time is up, the transmission configuration information of the new configuration is used as the started transmission configuration information.

For example, the version information of the new configuration received by the terminal is V5, and V5 includes the activation time, and the activation time is 16:00 to 20:00, then within a time period of 16:00 to 20:00, the terminal takes the received transmission configuration information of the version V5 of the new configuration as the activated transmission configuration information, and performs data reception matching.

In implementation, the terminal determines whether the transmission configuration is used as the enabled transmission configuration information according to whether the enabled time exists in the received newly configured transmission configuration information, so as to perform data receiving matching, and the terminal can update the transmission configuration used for data receiving in time according to whether the enabled time exists in the newly configured transmission configuration information, so as to ensure that the resource configuration used by the sending end and the receiving end is equal to the configuration of parameters directly related to sending demodulation and the like, and can successfully receive matching within the same communication range.

Optionally, after receiving the newly configured transmission configuration information, if the newly configured transmission configuration information does not include the activation time, the terminal sends the subsequent N data to be transmitted using the newly configured transmission configuration information; or

After receiving the newly configured transmission configuration information, if the newly configured transmission configuration information includes the enabling time, the terminal sends the subsequent N data to be transmitted by using the newly configured transmission configuration information after the enabling time is reached;

wherein N is a positive integer.

Specifically, after receiving the newly configured transmission configuration information, the terminal determines whether the newly configured transmission configuration information includes an enabling time, and if the newly configured transmission configuration information does not include the enabling time, the terminal uses the newly configured transmission configuration information as the enabled transmission configuration information and sends data to the newly configured transmission configuration information used by N subsequent data to be transmitted; if the transmission configuration information of the new configuration includes the activation time, the transmission configuration information of the new configuration is used as the activated transmission configuration information after the activation time is reached, and the N subsequent data to be transmitted are sent by using the transmission configuration information of the new configuration, which is described below.

In the first mode, the terminal sends the data by using the transmission configuration information with the new configuration when the transmission information with the new configuration received by the terminal does not contain the enabling time.

For example, the version information of the new configuration received by the terminal is V5, and V5 does not include the activation time, at this time, the N data that needs to be transmitted subsequently are sent using the transmission configuration information of the version V5 of the new configuration.

And in the second mode, the transmission information of the new configuration received by the terminal comprises the starting time, and after the starting time is up, the transmission configuration information of the new configuration is used for sending data.

For example, the version information of the new configuration received by the terminal is V5, and V5 includes the activation time, and the activation time is 16:00 to 20:00, then within a time period of 16:00 to 20:00, the transmission configuration information of the version V5 of the new configuration is used to send the N data that need to be transmitted subsequently.

In implementation, the terminal determines whether the transmission configuration is used as the enabled transmission configuration information according to whether the enabled time exists in the received transmission configuration information with the new configuration to send data, and the terminal can update the transmission configuration used when sending data in time according to whether the enabled time exists in the transmission configuration information with the new configuration, so that the resource configuration used by the sending end and the receiving end is equal to the configuration of parameters directly related to sending demodulation and the like, and the matching can be successfully received in the same communication range.

Optionally, the terminal updates the enabled transmission configuration information of multiple versions according to one or more of the following manners:

the terminal deletes the corresponding transmission configuration information when the failure time reaches;

after receiving the newly configured transmission configuration information, the terminal deletes the transmission configuration information of the lowest version which can be used and is lower than the transmission configuration information of the new configuration;

and if the number of the enabled transmission configuration information is equal to the set number, deleting the transmission configuration information with the lowest version after the terminal receives the transmission configuration information with the new configuration.

In the implementation process, the terminal may update the transmission configuration information of the enabled multiple versions, which may be specifically provided in multiple ways, which are described below respectively.

In the first mode, the terminal deletes the transmission configuration information corresponding to the arrival of the expiration time.

In all the transmission configuration information of the terminal, some transmission configuration information includes an enabling time, after the enabling time is reached, the transmission configuration information including the enabling time is used for carrying out data sending and/or receiving matching, but after the enabling time is passed, the enabling time is invalid, namely the invalid time is reached, and at this time, the terminal deletes the transmission configuration information with the invalid time.

For example, the transmission configuration information of the version V2 includes enabling time information, where the enabling time information is 12:00 to 14:00, and before the enabling time, that is, before 12:00, the transmission configuration information of the version V2 is stored in the terminal, but the transmission configuration of the version V2 is not enabled to perform data transmission and/or reception matching on the information; when the starting time is 12:00, the transmission configuration information of the version V2 is the started transmission configuration information, and data is sent and/or received and matched; after the enabling time, i.e. after 14:00, the transmission configuration information of the version V2 passes the enabling time, i.e. the enabling time is expired, and the version V2 is the transmission configuration information at which the expiry time arrives, at which time the terminal deletes the transmission configuration information of the version V2.

And in a second mode, after receiving the transmission configuration information with the new configuration, the terminal deletes the transmission configuration information with the lowest version which is lower than the lowest version which can be used and is indicated in the transmission configuration information with the new configuration.

The new transmission configuration information received by the terminal contains information indicating the lowest version which can be used by the terminal, but the terminal contains a plurality of versions of transmission configuration information, the information is higher than the lowest version which can be used, and the information lower than the lowest version which can be used exists, and the terminal already receives the information of the lowest version which can be used, so that the information lower than the lowest version which can be used in the terminal can not carry out data transmission and/or reception matching, and the terminal deletes the transmission configuration information lower than the lowest version which can be used and indicated in the transmission configuration information which is newly configured;

for example, the information of the new transmission configuration version received by the terminal includes information of the lowest version that can be currently used by the terminal as V3, and at this time, the terminal includes transmission configuration information of multiple versions: version V6, version V5, version V4, version V3, version V2, version V1, and transmission configuration information of version V2 and version V1 is lower than that of version V3, so the terminal deletes transmission configuration information of version V2 and transmission configuration information of version V1.

And in a third mode, if the number of the enabled transmission configuration information is equal to the set number, the terminal deletes the transmission configuration information with the lowest version after receiving the newly configured transmission configuration information.

And after receiving new transmission configuration information, if the received transmission configuration information is the enabled transmission configuration information and the number of the enabled transmission configuration information reaches the upper limit, the terminal deletes the transmission configuration information with the lowest version.

For example, the number of the fixed enabled transmission configuration information set in the terminal is 4, when the new transmission configuration information is the transmission configuration information of version V5 and V5 does not include the enabling time, the received transmission configuration information of version V5 is the enabled transmission configuration information, the terminal currently includes the transmission configuration information of versions V1, V2, V3, V4 and V5, the number of the transmission configuration information is greater than the set fixed number, and the transmission configuration information with the lowest version is the transmission configuration information of version V1, and the transmission configuration information with the lowest version, that is, the transmission configuration information of version V1, is deleted.

In implementation, the terminal updates the stored configuration information and deletes the invalid configuration information according to the received newly configured transmission configuration information, so that all the enabled transmission configuration information in the terminal can be matched with data transmission or/and reception, and the data can be received in time.

In a specific implementation process, if the version used for transmission is lower than the enabled highest version, the related information may be carried in the transmitted data during transmission, so as to notify the peer that the matched version is not the highest version of the transmission segment.

For different carried related information, the specific sending mode is also different, for example, a rollback identifier may be used as the related information or version information may be used as the related information. Described separately below.

The first mode is to adopt a rollback identifier as related information.

Wherein the fallback identification indicates that a version transmitted using the transmission configuration information is lower than the highest version enabled.

In a specific implementation, the terminal may determine whether a fallback identifier exists in the received data, for example, the fallback identifier may be represented by 1, after receiving the data, if the fallback identifier exists in the data, the terminal determines that the sending side performs version fallback, and if the fallback identifier does not exist in the data, the terminal determines that the sending side does not perform version fallback;

the terminal may further perform a judgment according to a specific bit value, for example, if there is rollback, the rollback flag is 1, if there is no rollback, the flag is 0, after the terminal receives the data, the terminal judges to identify the bit value on the rollback bit, if it is 1, it is determined that the sending side performs version rollback, and if it is 0, it is determined that the sending side does not perform version rollback.

Optionally, when the terminal determines to send the used version according to the matching result, for the transmission configuration information of any version, if the terminal successfully receives data after performing reception matching through the transmission configuration information of the version and the data does not include a rollback identifier, adding the version to a first alternative version set;

the terminal selects the lowest version from the first alternative version set as the version used for transmission;

specifically, the terminal has enabled multiple versions of transmission configuration information, performs data reception matching on any version of the transmission configuration information, and after receiving and matching the data successfully, the received data does not carry information of the rollback identifier, and then enters the version used for successfully receiving the data after receiving and matching into the first alternative version set, and then the terminal selects the lowest version in the first alternative version set as the version used for sending the data.

When the transmission configuration information of the versions is used for receiving and matching data, whether the data can be successfully received or not is mainly determined by the transmission configuration information of the version which is started in the terminal and the version configuration information which is used for sending, and if all the started transmission configuration information in the terminal cannot successfully receive and match the data, the terminal takes the highest version as the version which is used for sending;

if the data can be successfully received and the data does not carry the rollback identification, adding the version used when the data is successfully received into the first alternative version set, and selecting the lowest version from the first alternative version set as the version used for sending; if the data can be successfully received but the data carries the rollback identifier, the version used when the data is successfully received will not be added to the first local selection set, but the lowest version is still selected from the first local selection set as the version used for sending.

For example, the enabled version information in the terminal is V1, V2, V3, V4, and V4 is the highest version, V3 is the second highest version, and V1 is the lowest version.

Receiving data by using the enabled 4 versions, and if the data is not successfully received, transmitting the data by using the highest version V4 when transmitting the data;

receiving data by using the enabled 4 versions, and if the version V1 can successfully receive the data and the received data does not carry a rollback identifier, adding the version V1 to a first alternative version set; if the version V2 cannot successfully receive the data, not adding the version V2 to the first alternative version set; if the version V3 can successfully receive the data, but the received data carries a rollback identifier, not adding the version V3 to the first alternative version set; if the version V4 can successfully receive the data and the received data does not carry the rollback identification, adding the version V4 to a first alternative version set, wherein the versions contained in the first alternative version set include version V1 and version V4, and selecting the lowest version V1 from the requisite set as the version for sending use.

In implementation, the terminal performs data receiving matching according to the transmission configuration information of any one version that is started, and determines an appropriate version for data sending according to the version after the matching is successfully received by the transmission configuration information, so that the transmission configuration information corresponding to the version used for sending the data can be updated in time.

Optionally, after the terminal determines the version used for transmission according to the matching result, if the determined version is lower than the enabled highest version, the terminal adds a fallback identifier to the data to be transmitted.

Specifically, the terminal determines the version used for transmission according to the matching result, and if the determined version is lower than the enabled highest version, before transmitting data according to the transmission configuration information corresponding to the determined version, the terminal adds a rollback flag to the data to be transmitted, which indicates that the version currently transmitted by using the transmission configuration information is not the enabled highest version and is lower than the enabled highest version.

For example, the highest version in the terminal 3 is V3, the version used for transmission is determined to be V1 according to the matching result, at this time, the determined version V1 is lower than the highest version V3 in the terminal 3, and when data transmission is performed, a backoff flag is added to data to be transmitted.

In implementation, when the version used for transmission is determined to be lower than the highest version which is enabled, the backspacing identifier is added into the data transmitted by the terminal, and when other terminals receive the data, whether the version in the received data is the highest is determined according to whether the backspacing identifier exists, so that whether the version used for data transmission is updated according to the version is determined, the updating accuracy is ensured, and the final connection failure cannot be caused.

Initially, the V2X configuration function entity (V2X cloud) configures N pieces of version information, such as V1, V2, V3, V4 … … VN, to the terminal. At this time, the terminal has enabled three versions of V1, V2 and V3 for receiving and matching data, wherein V3 is the highest version and V1 is the lowest version. The current highest version of terminal 1 at this time is V1, for terminal 2 is V2, and for terminal 3 is V3.

When receiving the matching information, the terminal receives and matches data according to the descending order of the version, that is, the transmission configuration information of the highest version is used for receiving data first, if the reception is successful, the reception matching of the data packet is displayed to be successful, if the reception is failed, the next new version is used for receiving the data, and the reception matching is performed in sequence until the reception is successful or all the configuration information is failed, in the implementation, the transmission configuration information of the version V3 is used for receiving the data first, then the transmission configuration information of the version V2 is used for receiving the data, and finally the transmission configuration information of the version V3 is used for receiving the data.

In the implementation process, the terminal adjusts the transmission configuration information used by the terminal according to the received transmission configuration information used by other surrounding terminals.

Based on the above, there are many ways to determine the version of the terminal used for transmission, taking data V2X as an example, and various embodiments carrying the fallback identifier are described below from the perspective of the terminal 3.

In the first embodiment, the terminal 1, the terminal 2, and the terminal 3 are not in the direct communication range.

As shown in fig. 2, the communication ranges of the terminals 1, 2, and 3 are indicated by circular areas, and if they do not overlap, they are not in direct communication with each other.

Step 1, initially, the terminal 3 uses the transmission configuration information of the V3 version to carry out V2X transmission;

step 2, the terminal 3 uses the V3 version to perform V2X receiving matching, and does not successfully receive V2X data; the terminal 3 uses the V2 version to carry out V2X receiving matching, and does not successfully receive V2X data; the terminal 3 uses the V1 version to carry out V2X receiving matching, and does not successfully receive V2X data;

and 3, the terminal 3 adjusts and uses the version V2 to carry out V2X data transmission and carries a rollback identifier.

Specifically, the terminal 3 may perform receiving matching through the transmission configuration information with the version V2 and successfully receive data, and the received data does not carry a fallback identifier, and should add the version V2 to the first candidate version set, the first candidate version set includes the version V2, and select a lowest version from the first candidate set to perform data transmission, and at this time, select the transmission configuration information with the version V2 to perform data transmission, because the version V2 is lower than the highest version V3, when data transmission is performed using the transmission configuration information with the version V2, the fallback identifier should be carried in the data, which indicates that the currently used transmission version is not the highest version.

In the third embodiment, the terminal 1 and the terminal 2 can perform direct communication with the terminal 3 respectively.

As shown in fig. 4, the communication ranges of the terminal 1, the terminal 2, and the terminal 3 are indicated by circular areas, and if there is no overlap, the communication ranges are not in direct communication with each other; the presence of overlapping portions indicates that they are within direct communication range.

step 2, the terminal 3 uses the transmission configuration information with the version V3 to receive and match the V2X, and does not successfully receive the V2X data; the terminal 3 uses the transmission configuration information with the version V2 to perform V2X receiving matching, and successfully receives V2X data; the terminal 3 uses the transmission configuration information with the version V1 to perform V2X receiving matching, and successfully receives V2X data;

and step 3, the terminal 3 adjusts and uses the version V1 to send data and carries a rollback identifier.

Specifically, the terminal 3 may perform receiving matching through the transmission configuration information with the version V2 and the version V1 and successfully receive data, and the received data does not carry a fallback identifier, and should add the version V2 and the version V1 to the first candidate version set, the versions included in the first candidate version set have V2 and V1, and select a lowest version from the first candidate set to transmit data, at this time, the transmission configuration information with the version V1 is selected to transmit data, and because the version V1 is lower than the highest version V3, when the transmission configuration information with the version V1 is used to transmit data, the fallback identifier should be carried in the data, which indicates that the currently used transmission version is not the highest version.

Embodiment four, the operation of embodiment three is continued, at which time the terminal 1 moves out of the direct communication range of the terminal 3.

As shown in fig. 5, the communication ranges of the terminal 1, the terminal 2, and the terminal 3 are indicated by circular areas, and if there is no overlap, the communication ranges are not in direct communication with each other; the presence of overlapping portions indicates that they are within direct communication range.

Step 1, the terminal 3 uses the transmission configuration information with the version V1 to send V2X;

step 2, the terminal 3 uses the transmission configuration information with the version V3 to receive and match the V2X, and does not successfully receive the V2X data; the terminal 3 uses the transmission configuration information with the version V2 to perform V2X receiving matching, and successfully receives V2X data; the terminal 3 uses the transmission configuration information with the version V1 to perform V2X receiving matching, and does not successfully receive V2X data;

and step 3, the terminal 3 adjusts the transmission configuration information with the use version of V2 to carry out V2X transmission and carries the rollback identifier.

Specifically, since the fourth embodiment continues with the operation of the third embodiment, in the third embodiment, the terminal 3 determines to use the transmission configuration information with the version V1 to transmit the V2X, so that in the fourth embodiment, the version V1 is used to transmit the V2X, at this time, the terminal 1 has moved out of the communication range of the terminal 3, when the terminal 3 uses the version V1 to perform data reception matching, the terminal cannot receive matching successfully, and the terminal 2 is still within the communication range of the terminal 3, when the terminal 3 uses the version V2 to perform data reception matching, the terminal can receive matching successfully by the version V2, and because the received data does not carry a fallback flag, the version V2 is added to the first candidate set, which only has the version V2, so that the terminal 3 adjusts to use the version V2 to perform data transmission, but the highest version V3 in the terminal 3, the version V2 is lower than the version V3, and a backspacing identifier is added when data transmission is carried out.

In the fifth embodiment, the operation of the fourth embodiment is continued, the terminal 4 moves into the communication range of the terminal 3, the terminal 4 and the terminal 3 can directly communicate with each other, and the terminal 4 uses the transmission configuration information with the version V1 to perform data transmission and carries the rollback identifier.

As shown in fig. 6, the communication ranges of the terminals 1, 2, 3, and 4 are indicated by circular areas, and if there is no overlap, the communication ranges are not in direct communication with each other; the presence of overlapping portions indicates that they are within direct communication range.

Step 1, the terminal 3 uses the transmission configuration information with the version V2 to send V2X;

step 2, the terminal 3 uses the transmission configuration information with the version V3 to receive and match the V2X, and does not successfully receive the V2X data; the terminal 3 uses the transmission configuration information with the version V2 to perform V2X receiving matching, and successfully receives V2X data; the terminal 3 uses the transmission configuration information with the version V1 to perform V2X receiving matching, and successfully receives V2X data;

and step 3, the terminal 3 adjusts the transmission configuration information with the use version of V2 to carry out V2X transmission and carries the rollback identifier.

Specifically, since the fifth embodiment continues with the operation of the fourth embodiment, in the fourth embodiment, the terminal 3 determines to use the transmission configuration information with the version V2 to perform the transmission of V2X, and therefore, in the fourth embodiment, the terminal 3 uses V2 to perform the transmission of V2X, at this time, the terminal 1 has moved out of the communication range of the terminal 3, the terminal 4 has moved into the communication range of the terminal 3, and the terminal 4 uses the transmission configuration information with the version V1 to perform data transmission and carries the fallback identifier; when the terminal 3 performs reception matching of data using version V1, reception matching with the terminal 4 can be successful by version V1, and when the terminal 3 performs reception matching of data using version V2, reception matching can be successful by version V2; however, because the data in the terminal 4 carries the fallback flag, which indicates that the transmission configuration information with the version V1 is not the highest version among the transmission configuration information of the enabled multiple versions in the terminal 4, it is not possible to add the transmission configuration information with the version V1 to the first candidate version set, but the data received through the transmission configuration information with the version V2 does not carry the fallback flag, so that the version V2 is added to the first candidate set, and only the version V2 exists in the first candidate set, so that the terminal 3 may adjust the transmission of data using the version V2, but the highest version in the terminal 3 is V3, and the version V2 is lower than the version V3, and the fallback flag is also added when the data is transmitted.

Sixth embodiment, the operation of fifth embodiment is continued, and the terminal 2 moves out of the communication range of the terminal 3.

As shown in fig. 7, the communication ranges of the terminals 1, 2, 3, and 4 are indicated by circular areas, and if they do not overlap, they are not in direct communication with each other; the presence of overlapping portions indicates that they are within direct communication range.

Step 1, terminal 3 uses transmission configuration information with version V2 to send V2X;

step 2, the terminal 3 uses the transmission configuration information with the version V3 to receive and match the V2X, and does not successfully receive the V2X data; the terminal 3 uses the transmission configuration information with the version V2 to perform V2X receiving matching, and successfully receives V2X data; the terminal 3 uses the transmission configuration information with the version V1 to perform V2X receiving matching, and successfully receives V2X data;

and 3, the terminal 3 adjusts the transmission configuration information with the use version of V3 to carry out V2X transmission without carrying a rollback identifier.

Specifically, the sixth embodiment continues with the operation of the fifth embodiment, where it has been determined in the fifth embodiment that the transmission configuration information with the version V2 is used for sending data, and at this time, the terminal 3 uses the transmission configuration information with the version V3 to perform data receiving matching, and the receiving matching is not successful; the terminal 3 uses the transmission configuration information with the version of V2 to perform data receiving matching, and the terminal 2 with the version of V2 has moved out of the communication range of the terminal 3, so that the receiving matching is not successful; the terminal 3 uses the transmission configuration information with the version V1 to receive and match the data, and receives the message that the matching is successful, but because the terminal 4 carries the rollback identifier, the version V1 cannot be added into the first alternative version set at this time, so the terminal 3 continues to use the current highest version V3 to send the data, and does not carry the rollback identifier.

In the implementation process, the version used for sending of the terminal is adjusted according to the result of the transmission configuration information receiving matching, and meanwhile, the multiple versions started in the terminal are used for receiving data, so that the terminal can obtain configuration updating in time, and direct connection failure caused by untimely terminal updating or inconsistent configuration parameters can be avoided.

And the second mode is to adopt the version information as the related information.

The version information is used for uniquely representing a set of transmission configuration information, and the version information corresponding to different transmission configuration information is different. In actual use, bits of general version information are relatively large, and for convenience of description, the version information is represented by V1, V2.

Optionally, when the terminal determines the version used for transmission according to the matching result, the terminal selects the version with the lowest version from the versions included in all the received data as the version used for transmission.

Specifically, when determining the version to be used for transmission according to the matching result, the terminal may also determine the version according to the versions included in the data received by the terminal, and the terminal may select the lowest version from the versions included in all the received data as the version to be used for transmission.

The terminal can receive data in the same communication range, and the version contained in the received data is the current highest version of the terminal.

In implementation, the terminal determines the version used for transmission according to the version contained in the received data, and can update the transmission configuration information corresponding to the version used for transmission in time according to the received data.

Optionally, after the terminal determines the version used for transmission according to the matching result, the terminal adds the highest version that is enabled by the terminal to the data that needs to be transmitted before transmitting according to the transmission configuration information corresponding to the determined version.

Specifically, if the terminal determines that the version used for transmission is V2 according to the matching result, but the terminal uses the enabled highest version as V3, at this time, the enabled highest version V3 of the terminal is added to the data that needs to be transmitted before the data is transmitted according to the transmission configuration information corresponding to the determined version V2.

In implementation, after the terminal determines the version used for transmission according to the matching result, the terminal adds the highest version enabled by the terminal to the transmitted data before the determined version is used for transmitting the data, so that when other terminals receive the data, the highest version enabled by the terminal can be received, then the version used for transmission can be determined according to the highest version of the terminal in the data, the version used for transmission can be updated according to the highest version enabled in the terminal, and the timeliness and the accuracy of the version used for updating transmission by the terminal are guaranteed.

Based on the above, the following describes various embodiments of carrying version id from the perspective of the terminal 3 by taking V2X as an example.

Example nine: continuing with the operation of embodiment eight, terminal 4 (transmitting using version V1, but carrying its highest version V3) moves into direct communication range with each other by terminal 3.
