in LTE V2X R14/15, the Quality of Service (QoS) parameter information of a Side Link Radio Bearer (SLRB) may specifically include a Packet Priority (PPPP) and/or a Packet Reliability (PPPR).
The Packet Delay Budget (PDB) parameter is obtained by mapping PPPP, and the PPPP parameter includes a Delay requirement of V2X and a service priority parameter. PPPR is a reliability parameter of a service, and is mainly used to determine whether a retransmission technique is enabled.
(2) Existing 5G QoS architecture:
the 5G QoS parameters are identified by a 5G QoS identifier (5QI) and include resource type, priority level, packet delay budget, packet error rate, averaging window, maximum data burst size. Therein, the core network has defined some standardized 5QI parameters, as described in the following table.
Disclosure of Invention
The embodiment of the application provides a data transmission method and a data transmission device, which are used for managing and mapping the QoS (quality of service) parameters special for the 5G V2X service, and through the QoS parameters, a network side and a user equipment side can carry out bearing mapping and transmission parameter processing on a 5G V2X service data packet, so that the flexibility and the overall efficiency of realizing the 5G V2X service by a network are improved.
The data transmission method provided by the embodiment of the application comprises the following steps:
determining QoS parameters special for 5G V2X service which are required to be adopted currently from a QoS parameter table;
and transmitting data according to the QoS parameters.
According to the embodiment of the application, for a 5G V2X service, each V2X service data packet carries a QoS parameter index when data is transmitted, the method provided by the embodiment of the application can determine the corresponding QoS parameter in a preconfigured table according to the QoS parameter index, and by the QoS parameter, a network side and User Equipment (UE) can perform bearing mapping and processing of transmission parameters and the like on the 5G V2X service data packet, so that the flexibility and the overall efficiency of the network for realizing the 5G V2X service are improved.
Optionally, the QoS parameter table is preconfigured to the user equipment UE by one of the following:
standard specification;
signing data;
broadcasting a notification;
dedicated signaling.
Optionally, the QoS parameter table includes a correspondence between QoS parameters specific to 5G V2X traffic and QoS parameter indexes specific to 5G V2X traffic.
The corresponding relationship between the QoS parameters and the QoS parameter indexes may be that one QoS parameter index corresponds to a set of QoS parameters.
Optionally, the QoS parameters specific to the 5GV2X service that need to be adopted currently are determined from the QoS parameter table according to the QoS parameter index.
Optionally, the QoS parameters specific to the 5G V2X service include one or a combination of the following parameters:
a service priority;
a delay parameter, which may have a unit of ms;
block error rate, i.e. reliability, in%;
a payload, which may be in bytes;
data rate, which may be in units of Mbps;
the minimum communication distance may be in meters.
The subsequent UE directly carries the QoS parameter index when sending the data packet, and the UE and the entity at the side of the access network can acquire the corresponding QoS parameter according to the QoS parameter index by the method, thereby carrying out mapping and transmission processing which accord with the QoS requirement on the data packet, wherein the transmission processing comprises processing with different priorities.
Optionally, the method further comprises: and updating the QoS parameter table.
In actual deployment, there are many combinations of V2X service requirements, and the standard can be modified according to actual needs, and a new QoS parameter index and its corresponding QoS parameter can be defined or changed and added. The maximum advantage of the standardized QoS parameter table is that the method is simple, when a data packet is generated by a UE and a service layer of a network side, a proper QoS parameter combination is selected according to the characteristics and requirements of the data packet, and the QoS parameter index of the data packet is carried in the data packet, so that the corresponding QoS parameter can be found through the QoS parameter index when the data packet reaches any layer, and corresponding transmission processing is carried out.
However, the standard specification means that the whole standard field is uniform, and when changes are increased, the former UE of the low release cannot support the subsequent new services, so that the table needs to be updated.
Optionally, the QoS parameter table is updated by one of the following:
updating through operator QoS parameters;
when a terminal is attached to a network, if the terminal inquires that a network side has a latest QoS parameter table, the terminal downloads the latest QoS parameter table from the network side;
updating by broadcasting;
updated by dedicated signaling.
Optionally, the method provided in the embodiment of the present application further includes:
and informing the index of the QoS parameter to a data receiving end.
Since the QoS parameter index may also be directly used during communication between two UEs, or a service initiated by the UE uplink directly uses a configuration process avoiding the prior process, in order to enable the sending end and the receiving end to have the same processing mode for the same QoS parameter, that is, the sending end may also adopt the same processing mode for the QoS parameter, and then some advanced configuration process may be required. For example: the network side can inform the UE in a broadcasting or dedicated signaling pre-configuration mode, and automatically starts a repeating mechanism when the block error rate requirement is higher than a threshold of 99.99 and the delay requirement is lower than 10 ms.
Another embodiment of the present application provides a computing device, which includes a memory and a processor, wherein the memory is configured to store program instructions, and the processor is configured to call the program instructions stored in the memory, and execute, according to an obtained program:

standard specification;
signing data;
broadcasting a notification;
dedicated signaling.
Optionally, the QoS parameter table includes a correspondence between QoS parameters specific to 5G V2X traffic and QoS parameter indexes specific to 5G V2X traffic.
Optionally, the processor determines the QoS parameter specific to the 5G V2X service that needs to be adopted currently from the QoS parameter table according to the QoS parameter index.
Optionally, the QoS parameters specific to the 5G V2X service include one or a combination of the following parameters:
a service priority;
a delay parameter;
block error rate;
a payload;
a data rate;
minimum communication distance.
Optionally, the processor is further configured to:

Optionally, the processor updates the QoS parameter table by one of:
updating through operator QoS parameters;
when the terminal is attached to the network, if the terminal inquires that the network side has the latest QoS parameter table, downloading the latest QoS parameter table from the network side;
updating by broadcasting;
updated by dedicated signaling.
Optionally, the processor is further configured to: and informing the index of the QoS parameter to a data receiving end.
Another embodiment of the present application provides a computer storage medium having stored thereon computer-executable instructions for causing a computer to perform any one of the methods described above.

a determining unit, configured to determine QoS parameters specific to the 5G V2X service that needs to be adopted currently from a QoS parameter table;
and the sending unit is used for transmitting data according to the QoS parameters.
Optionally, the QoS parameter table includes a correspondence between QoS parameters specific to 5G V2X traffic and QoS parameter indexes specific to 5G V2X traffic.
Optionally, the QoS parameters specific to the 5GV2X service that need to be adopted currently are determined from the QoS parameter table according to the QoS parameter index.

Various embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the display sequence of the embodiment of the present application only represents the sequence of the embodiment, and does not represent the merits of the technical solutions provided by the embodiments.
The 5G core network has no concept of Bearer (Bearer), and the QoS parameters issued to the NG-NB of the next generation base station are configured in a manner of stream granularity and adopting a 5G QoS identifier (5QI) mode, and in addition, as the NG-NB of the access network still performs QoS management in a manner of infinite Bearer (RB) granularity, the access network needs to generate the QoS parameters at the RB level for the interaction process between the NG-NB and the UE and between the NG-NB and other wireless access entities. In the vehicle networking LTE V2X of the release 14/15, simplified PPPP and PPPR are adopted as QoS parameter transfer, and various operations of V2X QoS are completed. However, in 5G V2X, there is currently no mature QoS management mechanism. The following embodiments of the present application provide a QoS management and mapping method dedicated to a service of 5G V2X, which can complete mapping and management of all V2X parameters, and improve flexibility and overall efficiency of network configuration.
Example one, the standard specifies.
In order to save signaling overhead and reduce time delay, the simplest definition mode of V2X QoS parameters is directly specified by the standard, and specific parameter configuration is shown in fig. 1.
The QoS parameter table shown in fig. 1 does not include the priority parameter in the embodiment of the present application, but may include the priority parameter in practical applications.
In the first embodiment of the present application, the QoS requirements of a typical V2X service are listed as values of a typical QoS parameter index, but in practical applications, there are more than this combination of V2X service requirements, and a standard may be modified according to actual needs, and a new QoS parameter index and its corresponding QoS parameter may be defined or modified and added.
The standardized QoS parameter table has the advantages that the standardized QoS parameter table is simple, when a data packet is generated by a UE and a service layer at a network side, according to the characteristics and requirements of the data packet, appropriate QoS parameter(s) are selected, and the QoS parameter index of the QoS parameter(s) is carried in the data packet, so that when the data packet reaches any layer, the corresponding QoS parameter can be found through the QoS parameter index, and corresponding transmission processing is carried out.
Embodiment two, notification in advance.
When the change is increased, it may affect that the former UE of the low release cannot support the subsequent new service, so the QoS parameter table needs to be updated in the following manner:
in the first mode, by updating the QoS parameters of the operator, that is, by adopting a subscription data mode, when the UE opens the V2X service, the subscribed operator pre-configures some pre-configured QoS parameter mapping tables into the UE, so that the UE can use these QoS parameter indexes subsequently. When updating is carried out subsequently, the UE can update the QoS parameter index information through an operator, and when the version or software is updated, the UE can support the subsequent new service;
secondly, the UE adopts a pre-downloading mode, when the UE is attached to a network, the UE inquires whether the UE has the latest QoS parameter table, if not, the UE adopts a downloading mode again, and the latest QoS parameter table is obtained from a network side;
in a third way, the network side may broadcast the QoS parameter table so that all V2X UEs obtain the latest QoS parameter table. The broadcast may be in an On demand (On demand) manner, and the UE triggers acquisition as needed to reduce network overhead. For example: the UE finds that the UE does not store any QoS parameter index, and the network supports V2X QoS parameter index broadcasting, so that the UE can enable the network to broadcast the QoS parameter table in a request mode; or the network side broadcasts the latest version number of the QoS parameter table of 6, and the UE finds that the version number stored in the UE is 4, the UE may also request to broadcast the latest version number of the QoS parameter table of 6.
In the fourth mode, when the UE finds that it has no QoS parameter table, or the table version is too old, the UE may request the network through dedicated signaling, and the network sends the latest QoS parameter table to the UE.
Generally, whatever the update mode of the QoS parameter table, an incremental update is required on the previous version, so that it can be ensured that the previous QoS parameter is valid and still works. The length of the QoS parameter index can be defined as 8 bits (256 values) or 16 bits (65536 values), etc., and can be gradually upgraded as the service increases.
Embodiment three, use of QoS parameter indices.
The association between the 5G V2X service and the QoS parameter index is mainly established by the transmission contents, and the transmission requirements are determined according to the transmission contents so as to correspond to the QoS parameter index.
When all data packets sent by the high layer carry QoS parameter indexes along with the packets, all corresponding QoS parameters can be found through the QoS parameter indexes. Generally, when the access network performs mapping of Data packets to Data Radio Bearers (DRBs), the access network may map Data packets with the same or similar QoS requirements to one DRB, for example: mapping all data packets with the QoS parameter index of 4 to one DRB, and mapping all data packets with the QoS parameter index of 8 to another DRB; or, when the data packets corresponding to QoS parameter index 3 and QoS parameter index 5 may both have the requirement of 99.999% block error rate and the requirement of 10ms delay, and the priorities are 5 and 4, respectively, the data packets of the two QoS parameter indexes may both be mapped to one DRB. After the mapping is completed, the relevant parameters of the DRB need to be determined, for example: the DRB of traffic with block error rate requirement 90 or 99 can adopt unacknowledged mode UM transmission, while those with block error rate requirement higher than or equal to 99.999 need to adopt acknowledged mode AM transmission, or UM repeated duplicate transmission.
In addition, resource selection, resource preemption, retransmission and the like related to the physical layer are also distinguished and processed according to different QoS parameters corresponding to the QoS parameter indexes, so that different QoS requirements are met, and the resource utilization efficiency is maximized.
Embodiment four, the way of using QoS parameter index is notified.
Because the QoS parameter index may also be used directly during communication between two UEs, or directly used by a service initiated by a UE uplink, thereby avoiding an advanced configuration process, in order to enable the sending end and the receiving end to have the same processing mode for the same QoS parameter, i.e., the sending end may use the same processing mode for the QoS parameter, and the receiving end may also use the same processing mode, the QoS parameter index needs to be configured in advance.
For example: the network side can inform the UE through broadcasting, special signaling and pre-configuration modes, and when the block error rate requirement is higher than a threshold of 99.99 and the time delay requirement is lower than 10ms, a repeated duplification mechanism is automatically started.
In summary, since the existing V2X QoS management mechanism only has the rank configuration of PPPP and PPPR, the included parameters are relatively few, and the rank is limited, which cannot fully reflect different QoS requirements. Although the existing QoS management mechanism of 5G is more sophisticated in QoS management and mapping, it needs to perform a signaling procedure in advance, and a service with a higher requirement for V2X delay cannot enter into transmission immediately, so the method for providing data transmission according to the embodiment of the present application includes a QoS management mechanism adapted to 5G V2X, see fig. 2, which includes:
s101, determining QoS parameters special for 5G V2X service which are required to be adopted currently from a QoS parameter table;
such as payload, transmission rate, maximum delay parameter, block error rate, data rate, communication distance, etc. in fig. 1.
And S102, transmitting data according to the QoS parameters.
Optionally, the QoS parameter table is preconfigured to the user equipment UE by one of the following:
the standard specification, for example, directly specifies according to the definition mode of the V2X QoS parameter in fig. 1;
when the service changes, it may affect that the UE before the low version cannot support the subsequent newly added service, and the QoS parameter table may be updated or preconfigured according to the method described in the second embodiment, including:
signing data;
broadcasting a notification;
dedicated signaling.
Optionally, the QoS parameter table includes a correspondence between QoS parameters specific to 5G V2X traffic and QoS parameter indexes specific to 5G V2X traffic.
The corresponding relationship between the QoS parameters and the QoS parameter indexes may be that one QoS parameter index corresponds to a set of QoS parameters.
Optionally, the QoS parameters specific to the 5GV2X service that need to be adopted currently are determined from the QoS parameter table according to the QoS parameter index.
Optionally, the QoS parameters specific to the 5G V2X service include one or a combination of the following parameters:
a service priority;
a delay parameter, which may have a unit of ms;
block error rate, i.e. reliability, in%;
a payload, which may be in bytes;
data rate, which may be in units of Mbps;
the minimum communication distance may be in meters.
The subsequent UE directly carries the QoS parameter index when sending the data packet, and the UE and the entity at the side of the access network can acquire the corresponding QoS parameter according to the QoS parameter index by the method, thereby carrying out mapping and transmission processing which accord with the QoS requirement on the data packet, wherein the transmission processing comprises processing with different priorities.
Optionally, the method further comprises: and updating the QoS parameter table.
Optionally, the QoS parameter table is updated by one of the following:
updating through operator QoS parameters;
when a terminal is attached to a network, if the terminal inquires that a network side has a latest QoS parameter table, the terminal downloads the latest QoS parameter table from the network side;
updating by broadcasting;
updated by dedicated signaling.
Optionally, the method provided in the embodiment of the present application further includes:
and informing the index of the QoS parameter to a data receiving end. For example, in the fourth embodiment, because the QoS parameter index may also be directly used during communication between two UEs or directly used by a service initiated by an uplink of the UE, advance configuration is avoided, and it is necessary for the sending end and the receiving end to have the same processing mode for the same QoS parameter, and it is necessary to advance configure the QoS parameter index. For example: the network side can inform the UE in a broadcasting or dedicated signaling pre-configuration mode, and automatically starts a repeated duplification mechanism when the block error rate requirement is higher than a threshold of 99.99 and the time delay requirement is lower than 10 ms.
The data transmission method provided by the embodiment of the application is applicable to both the UE side and the network side.
Correspondingly to the method, an embodiment of the present application further provides an apparatus for data transmission, which is shown in fig. 3 and includes:
a determining unit 11, configured to determine QoS parameters specific to a 5G V2X service that needs to be adopted currently from a QoS parameter table;
a sending unit 12, configured to transmit data according to the QoS parameter.
Optionally, the apparatus may further include an updating unit, configured to update the QoS parameter table by one of:

updated by dedicated signaling.
Optionally, the apparatus may further include a notification unit configured to notify a data receiving end of the index of the QoS parameter.
