Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, fig. 1 is a schematic structural diagram of a V2X system. The V2X system includes a base station 1 and a terminal 2, where the base station 1 may include various macro base stations, micro base stations, relay stations, access points, etc., and the terminal 2 may be various electronic devices such as handheld devices, vehicle-mounted devices, wearable devices, etc., with wireless communication functions, and may be applied to vehicles, infrastructures, etc. The base station 1 and the terminal 2 may be connected through an air interface technology (such as NR UU), and the terminal 2 may be connected through a Sidelink. The sildelink communication mode implements addressing by the source identifier and the target identifier of a Media Access Control (MAC) layer. No pre-connection between terminals 2 is required before transmission.
The V2X use cases are roughly classified into the following four types:
(1) vehicle formation (Vehicles platonic) allows Vehicles to dynamically form a formation for co-travel. All vehicles in the formation obtain information from the command vehicle to manage the formation that allows the vehicles to travel closer together than usual in a coordinated manner, in the same direction, and together.
(2) Extended Sensors (Extended Sensors) allow the exchange of raw or processed data collected through local Sensors or real-time video images between vehicles, Road Side Units (RSUs), pedestrian devices and V2X application servers. The vehicles can enhance the perception capability to the environment, exceed the detection range of the sensors of the vehicles, and have wider and more comprehensive opinions on the local conditions. High data rates are one of its key features.
(3) Advanced Driving (semi-automatic or fully automatic Driving) can be realized. Each vehicle and/or roadside unit shares sensory data obtained from its local sensors with nearby vehicles, allowing the vehicles to synchronize and coordinate their travel trajectories. Each vehicle shares its travel information with its neighboring vehicles.
(4) Remote Driving (Remote Driving) enables a Remote driver or V2X application to operate a Remote vehicle for passengers of the Remote vehicle who cannot drive themselves or are located in a hazardous environment. For situations with limited variation and predictable routes, such as public transportation, cloud computing based driving may be used, with the main requirements being high reliability and low latency.
The concept of group cast was introduced in sildelink, mainly for the above-mentioned use case of vehicular platonic. In the groupcast, the physical layer supports the functions of hybrid automatic Repeat request (HARQ) feedback and hybrid automatic Repeat combining. When the Sidelink HARQ feedback is enabled for groupcast, it is supported to use TX-RX (transmitting terminal-Receiving terminal) distance and/or Reference Signal Receiving Power (RSRP) to decide whether to send HARQ feedback. The HARQ feedback of Groupcast supports two options:
option 1: if the receiving terminal fails to decode the corresponding Transport Block (TB) after decoding the associated Physical Sidelink Control Channel (PSCCH), then HARQ-NACK (non-acknowledgement) is transmitted on the Physical Sidelink Feedback Channel (PSFCH), otherwise no signal is transmitted on the PSFCH.
Option 2: if the receiving terminal successfully decodes the corresponding TB, HARQ-ACK (decoding success) is transmitted on the PSFCH. After decoding the relevant PSCCH targeted for the receiving terminal, HARQ-NACK is transmitted on the PSFCH if the corresponding TB cannot be successfully decoded.
As shown in fig. 2, fig. 2 is a schematic flowchart of a data transmission method provided in an embodiment of the present application, where the data transmission method is applied to an electronic terminal, and the electronic terminal may be the terminal 2 in fig. 1. The specific flow of the data transmission method may be as follows:
101. and receiving service data and corresponding SCI information sent by a sending terminal, wherein the SCI information comprises priority.
In the embodiment of the present application, the sending terminal mayBeing terminal 2 in fig. 1, the electronic terminal may be a receiving terminal. In the V2X service, the QoS parameters may include priority, transmission rate, delay, reliability, security, and the like, and the priority in the QoS parameters is used for handling different communication modes, such as different propagation modes, or communication services with different urgency. When the service data cannot satisfy all the QoS requirements, the service data needs to be processed in a priority order by priority. After the transmitting terminal acquires the Qos parameters, the priority in the Qos parameters passes through the first-level SCI (1)ststage SCI) information, and indication information that a work assumption (work assumption) of the priority has been made is 3 bits. The definition and specific values of the priority in the first level SCI are determined by the RAN2, and the mapping between the priority and Qos parameters is also determined by the RAN 2.
The electronic terminal can send a service request to the core network through the sending terminal, the sending terminal receives service data and corresponding QoS parameters sent by the core network according to the service request, the sending terminal maps the QoS parameters and the priority, and the priority is set in the SCI information so as to send the service data and the corresponding SCI information to the electronic terminal.
102. And acquiring a communication distance threshold corresponding to the priority.
In the embodiment of the application, since the SCI information does not include the communication distance threshold, in order to meet the QoS requirement and improve the efficiency of controlling signaling resources, the priority and the communication distance threshold form a mapping relationship, so that the electronic terminal can obtain the corresponding communication distance threshold according to the priority in the SCI information.
In one embodiment, the priority levels and the communication distance threshold values may form a one-to-one mapping relationship to form a communication distance threshold value table, that is, each priority level in the communication distance threshold value table corresponds to a unique communication distance threshold value. The communication distance threshold value table may be pre-configured to the electronic terminal and the transmitting terminal through a high-level signaling.
For example, a plurality of priorities 000, 001, …, 111 of data are predetermined, and a plurality of communication distance thresholds X1, X2, …, X8 are determined. The multiple priorities 000, 001, …, and 111 may be arranged in order of priority from high to low, that is, the priority 000 is the highest, and the priority 111 is the lowest, and the multiple communication distance thresholds X1, X2, …, and X9 may be arranged in order of numerical value from large to small, that is, the communication distance threshold X1 is the largest, and the communication distance threshold X9 is the smallest. The mapping of the plurality of priorities 000, 001, …, 111 to the plurality of communication distance thresholds X1, X2, …, X9 in a one-to-one correspondence is shown in table 1, that is, the higher the priority is, the larger the corresponding communication distance threshold is, the lower the priority is, and the smaller the corresponding communication distance threshold is.
| Priority level | Communication distance threshold |
| 000 | X1 |
| 001 | X2 |
| 010 | X3 |
| 011 | X4 |
| 100 | |
| 101 | X6 |
| 110 | X7 |
| 111 | X8 |
TABLE 1
It should be noted that, according to different scene requirements, mapping relationships between the multiple priorities and the multiple communication distance thresholds may also be different, an order of the multiple priorities and an order of the multiple communication distance thresholds may be configured by a higher layer, and a mapping relationship between the multiple priorities and the multiple communication distance thresholds may also be configured by a higher layer.
In another embodiment, the priority and the communication distance requirement may form a one-to-one mapping relationship to form a communication distance requirement table, but the communication distance requirement includes at least one communication distance candidate. If the communication distance requirement comprises a communication distance candidate value, the communication distance candidate value is the communication distance threshold value, and if the communication distance requirement comprises a plurality of communication distance candidate values, the electronic terminal determines one communication distance candidate value from the plurality of communication distance candidate values as the communication distance threshold value. The communication distance requirement table may be pre-configured to the electronic terminal and the transmitting terminal through high-level signaling.
Specifically, the obtaining of the communication distance threshold corresponding to the priority information specifically includes:
searching a preset communication distance requirement table, and acquiring a communication distance requirement corresponding to the priority; the communication distance requirement comprises at least one communication distance candidate;
determining the communication distance threshold from the at least one communication distance candidate.
For example, the plurality of priorities 000, 001, …, 111 of the data are predetermined, and a plurality of communication distance candidates a1, a2, …, B1, …, H1, H2, … are determined, and the communication distance candidates having little influence on performance among the plurality of communication distance candidates may be divided into a set of communication distance requirements, such as the communication distance candidates for which a1, a2, a … are a set of communication distance requirements, the communication distance candidates for which B1 is a set of communication distance requirements, and the like. The multiple priorities 000, 001, …, 111 can be arranged in the order of priority from high to low, i.e. the priority 000 is the highest, the priority 111 is the lowest, the multiple groups of communication distance requirements can be arranged in the order of numerical values from large to small, i.e. the overall numerical value of a1, a2, … is the largest, the overall numerical value of H1, H2, … is the smallest, and each numerical value of a1, a2, … is larger than each numerical value of H1, H2, …. The multiple priorities 000, 001, …, and 111 are mapped in one-to-one correspondence with the multiple communication distance requests, as shown in table 2, that is, the higher the priority, the larger the communication distance candidate value in the corresponding communication distance request, and the lower the priority, the smaller the communication distance candidate value in the corresponding communication distance request.
| Priority level | Communication distance requirements |
| 000 | A1、A2、… |
| 001 | B1 |
| 010 | C1、C2、… |
| 011 | D1、D2、… |
| 100 | |
| 101 | F1 |
| 110 | G1、G2、… |
| 111 | H1、H2、… |
TABLE 2
It should be noted that, according to different scene requirements, mapping relationships between multiple priorities and multiple communication distance requirements may also be different, an order of the multiple priorities and an order of the multiple communication distance requirements may be configured through a higher layer, and a mapping relationship between the multiple priorities and the multiple communication distance requirements may also be configured through a higher layer.
After the communication distance requirement corresponding to the priority is obtained, if the communication distance requirement includes a plurality of communication distance candidate values, the communication distance threshold may be determined from the plurality of communication distance candidate values in a plurality of ways. For example, a communication distance candidate value is randomly selected from a plurality of communication distance candidate values as a communication distance threshold, or the communication distance threshold is determined by higher layer signaling, or an index of 2 bits is added to SCI information to determine the communication distance threshold by the index.
Specifically, the determining the communication distance threshold from the at least one communication distance candidate value specifically includes:
and searching a preset index table, and acquiring a communication distance candidate value corresponding to the index from the at least one communication distance candidate value to serve as the communication distance threshold.
For example, the candidate communication distance values in the set of communication distance requirements are a1, a2, A3 and a4, the index corresponding to a1 is set to 00, the index corresponding to a2 is set to 01, the index corresponding to A3 is set to 10, and the index corresponding to a4 is set to 11. The electronic terminal may further determine a communication distance threshold (e.g., a3) based on the index in QoS (e.g., 10).
103. And processing the service data according to the communication distance threshold.
In the embodiment of the present application, the larger the communication distance threshold is, the larger the communication range required by the communication distance is. The electronic equipment carries out different processing on the service data by detecting the communication distance between the electronic equipment and the sending terminal and judging whether the communication distance is within the communication range required by the communication distance.
Specifically, the processing the service data according to the communication distance threshold specifically includes:
detecting a communication distance between the electronic terminal and the sending terminal;
and if the communication distance does not exceed the communication distance threshold, feeding back response information to the sending terminal.
It should be noted that the location information of the transmitting terminal passes through the second-level SCI (2)ndstage SCI), and the electronic terminal calculates the communication distance between the electronic terminal and the sending terminal after acquiring the position information of the sending terminal. If the communication distance between the electronic terminal and the transmitting terminal is less than or equal to the communication distance threshold, the electronic terminal feeds back response information, that is, HARQ feedback, for a Physical downlink Shared Channel (pscch). If the communication distance between the electronic terminal and the transmitting terminal is greater than the communication distance threshold, the electronic terminal will not transmit HARQ feedback for the psch.
Therefore, the data transmission method provided by the application can receive the service data and the corresponding SCI information sent by the sending terminal, obtain the communication distance threshold corresponding to the priority in the SCI information, and process the service data according to the communication distance threshold, so that the value of the communication distance requirement is not set in the SCI information, signaling cost is saved, and the QoS requirement is met.
Referring to fig. 3, it is another schematic flow chart of the data transmission method provided in the embodiment of the present application, where the data transmission method is applied to an electronic terminal, and a specific flow of the data transmission method may be as follows:
201. and receiving service data and corresponding SCI information sent by a sending terminal, wherein the SCI information comprises priority and an index.
For example, the electronic terminal M is a receiving terminal, and the electronic terminal M receives the service data and the corresponding SCI information sent by the sending terminal N, and recognizes that the priority in the SCI information is 101 and the index is 00.
202. Searching a preset communication distance requirement table, and acquiring a communication distance requirement corresponding to the priority; the communication distance requirement includes at least one communication distance candidate.
For example, the preset communication distance requirement table is shown in table 3, and the electronic terminal M may obtain that the communication distance requirement corresponding to the priority 101 includes 2 communication distance candidate values 180 and 200 by looking up the table. In the communication distance requirement table, the priorities are arranged in the order from high to low, the communication distance requirements are arranged in the order from large to small, and the communication distance candidate value in the communication distance requirement corresponding to the high priority is larger than the communication distance candidate value in the communication distance requirement corresponding to the low priority.
| Priority level | Communication distance requirement (rice) |
| 000 | 1000 |
| 001 | 700 |
| 010 | 500 |
| 011 | 400 |
| 100 | 350 |
| 101 | 200、180 |
| 110 | 80 |
| 111 | 50 |
TABLE 3
203. And searching a preset index table, and acquiring a communication distance candidate value corresponding to the index from the at least one communication distance candidate value to serve as the communication distance threshold.
For example, in the index table, the index 00 corresponds to the first data, the index 01 corresponds to the second data, and so on, so that the electronic terminal M queries the index table, and can determine that the index 00 corresponds to the communication distance candidate 200, so as to use the communication distance candidate 200 as the communication distance threshold, that is, the communication distance threshold obtained by the electronic terminal M is 200.
204. And detecting the communication distance between the electronic terminal and the sending terminal.
For example, the electronic terminal M detects that the communication distance between it and the sending terminal N is 150 meters.
205. And if the communication distance does not exceed the communication distance threshold, feeding back response information to the sending terminal.
For example, if the electronic terminal M detects that the communication distance (150 meters) between the electronic terminal M and the transmitting terminal N is smaller than the communication distance threshold (200 meters), the electronic terminal M feeds back corresponding information, that is, HARQ feedback, to the transmitting terminal N.
The embodiment of the application combines the priority and the index to determine the threshold value of the communication distance between the electronic terminal M and the sending terminal N, so as to meet the QoS requirement and save the signaling overhead.
