Description
Technical Field
The invention relates to the technical field of communication, in particular to a communication technology calculation method and device.
Background
Vehicle to evolution (V2X) is a new generation of information communication technology that connects vehicles to Everything, where V represents a Vehicle, X represents any object that interacts information with the Vehicle, and X currently mainly contains vehicles, people, traffic side infrastructure and networks. The information mode of V2X interaction includes: Vehicle-to-Vehicle (V2V), Vehicle-to-road (V2I), Vehicle-to-person (V2P), and Vehicle-to-Network (V2N). In order to satisfy the interaction between a vehicle and various objects, especially the direct communication between two User Equipments (UEs), a direct communication (Sidelink, or translated into a side link, etc.) mode is introduced. The Sidelink communication mode implements addressing by a source identifier and a target identifier of a Media Access Control (MAC) layer. No pre-connection between UEs is required before transmission. Sildelink thus satisfies a more rapid and efficient communication approach. The System Architecture (SA) working group 1(WG1: work group 1) defines the first phase requirements for supporting the enhanced V2X use case in [3GPP TR 22.186], which is roughly divided into four use cases: vehicle Platooning (Vehicles), Extended Sensors (Extended Sensors), Advanced Driving (Advanced Driving), Remote Driving (Remote Driving).
The concept of group cast was introduced in sildelink, mainly for the above-described use case of vehicle formation driving. The physical layer in the groupcast supports the function of Hybrid Automatic repeat request (HARQ) feedback and Hybrid Automatic repeat request combination. When sidelink HARQ feedback is enabled for groupcast, it is supported to use TX-RX (transmit-receive end) distance and/or Reference Signal Received Power (RSRP) to decide whether to send HARQ feedback. In the 3GPP RAN1#97 conference, companies have agreed that for HARQ feedback based on TX-RX distance in groupcast, if TX-RX distance is less than or equal to communication distance requirement (communicative), the UE transmits HARQ feedback for physical downlink Shared Channel (psch). Otherwise, the UE will not transmit HARQ feedback for the psch. And the above-mentioned communication distance requirements can be obtained by decoding the SCI.
Currently 3GPP has confirmed that HARQ feedback (NACK feedback only) for groupcast based on TX-RX distance will be supported. Zone (zone) partitioning is configured based on the actual geographic zone, and the number of zone (zone id) where the transmitting end is located is carried by the SCI. However, for the physical layer, it is difficult to obtain the TX-RX distance without relying on 3 gpp-independent techniques. Global Navigation Satellite Systems (GNSS) perform poorly in tunnels or under the influence of obstacles in cities. Even in the poor case of city centers, GNSS may not be able to maintain accuracy over a large area or in the case of many vehicles. In this case, how to process the position information of the transmitting end that cannot be acquired is a problem to be solved.

The embodiment of the invention provides a communication distance calculation method and device. The application device is integrated in a mobile terminal, and the terminal can be a vehicle-mounted terminal or other equipment.
The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
A communication distance calculation method comprising: storing historical position information of a transmitting terminal; acquiring position loading data according to the historical position information, and loading the position loading data to side link control information; and transmitting the side link control information to a receiving end, and calculating the distance between the transmitting end and the receiving end.
As shown in fig. 1, a specific flow of the communication distance calculation method may be as follows:
101. historical location information of the transmitting end is stored.
For example, the transmitting terminal stores the position information obtained by the global navigation satellite system, and when the GNSS signal is lost and the position information of the transmitting terminal cannot be obtained, the position information stored by the transmitting terminal is used as the historical position information.
102. And acquiring position loading data according to the historical position information, and loading the position loading data to the side link control information.
For example, when a vehicle as a transmitting end runs in a tunnel or on a congested street in a city center, although the GNSS signal is easily lost, the running speed of the vehicle is not high, and particularly, the speed of the vehicle is low on a congested road. At this time, the transmitting end multiplexes the latest historical position information in the stored historical position information, and uses the position information as the position information of the transmitting end at the moment.
When the transmitting end is in a congestion condition, the historical position information multiplexed by the transmitting end is loaded into the second-level sidelink control information as the position loading data of the transmitting end. And when the transmitting terminal cannot normally obtain the position information of the transmitting terminal, calculating the distance between the receiving terminal and the transmitting terminal by taking the position loading data as the position information of the transmitting terminal.
When the vehicle as the receiving end runs on the expressway, the running direction and speed are regular, the transmitting end calculates the position offset, the latest historical position information stored in the transmitting end is corrected according to the calculated position offset, and the corrected position information of the transmitting end is loaded into the second-level side link control information as position loading data.
When the vehicle serving as the transmitting end is in a condition of regular driving direction and speed, the transmitting end can predict the traveling displacement of the vehicle, quantize the displacement to generate the position offset of the transmitting end, and the sum of the position offset of the transmitting end and the latest historical position information is the position information of the transmitting end at the moment.
103. And transmitting the side link control information to a receiving end, and calculating the distance between the transmitting end and the receiving end.
For example, the transmitting end transmits the second-level sidelink control information to the receiving end, the distance between the transmitting end and the receiving end is calculated in the receiving end, the position information of the receiving end can be obtained, the second-level sidelink control information transmitted by the transmitting end is received, the position information of the transmitting end at the moment is obtained from the second-level sidelink control information, and the distance between the two pieces of user equipment is calculated according to the positions of the transmitting end and the receiving end.
A communication distance calculation method comprising: loading historical position information of a transmitting terminal to side link control information, receiving the side link control information, and storing the historical position information; and acquiring the position loading data of the transmitting terminal according to the historical position information, and calculating the distance between the transmitting terminal and the receiving terminal.
As shown in fig. 2, a specific flow of the communication distance calculation method may be as follows:
201. and loading historical position information of a transmitting terminal into side link control information, receiving the side link control information, and storing the historical position information.
For example, the transmitting end transmits the position information obtained by the global navigation satellite system to the receiving end, the receiving end receives and stores the position information transmitted by the transmitting end, when the GNSS signal is lost and the position information of the transmitting end cannot be obtained, the transmitting end does not transmit the position information to the receiving end any more, and the position information of the transmitting end stored before the receiving end is the historical position information of the transmitting end at this time.
The position information of the transmitting terminal is loaded into the second-level side link control information and transmitted to the receiving terminal, and the receiving terminal acquires the position information of the transmitting terminal by receiving the second-level side link control information.
202. And acquiring the position loading data of the transmitting terminal according to the historical position information, and calculating the distance between the transmitting terminal and the receiving terminal.
For example, when a vehicle as a transmitting end runs in a tunnel or on a congested street in a city center, although the GNSS signal is easily lost, the running speed of the vehicle is not high, and particularly, the speed of the vehicle is low on a congested road. At this time, the receiving end multiplexes the latest historical position information in the historical position information of the transmitting end stored by the receiving end, and the position information is used as the position information of the transmitting end at the moment.
The receiving end receives and stores the position information transmitted by the transmitting end each time, and the new position information covers the old position information.
When the vehicle as the receiving end runs on the expressway, the running direction and speed are regular, the transmitting end calculates the position offset and transmits the position offset to the receiving end through the sideline control information. And the receiving end receives the position offset of the transmitting end, and calculates the position loading data of the transmitting end according to the position offset and the historical position information of the transmitting end stored in the receiving end. And when the transmitting terminal cannot normally obtain the position information of the transmitting terminal, calculating the distance between the receiving terminal and the transmitting terminal by taking the position loading data as the position information of the transmitting terminal.
When the vehicle serving as the transmitting end is in a state of regular driving direction and speed, the transmitting end can predict the traveling displacement of the vehicle and quantize the displacement to generate the position offset of the transmitting end. The position offset of the transmitting terminal can be transmitted by the first-stage side link control information and also can be transmitted by the second-stage side link control information.
The receiving end can acquire the own position information of the receiving end, and the stored historical position information of the transmitting end is corrected through the transmitting end offset in the received side link control information, so that the corrected position information of the transmitting end is obtained, and then the distance between the receiving end and the transmitting end is obtained through calculation according to the positions of the transmitting end and the receiving end.
In order to better implement the above method, an embodiment of the present invention may further provide a communication distance calculating apparatus, which may be specifically integrated in a network device, where the network device may be a mobile terminal or the like.
For example, as shown in fig. 3, the communication distance calculation apparatus may include a storage unit 301, an acquisition unit 302, and a transmission unit 303, as follows:
(1) memory cell 301
The storage unit 301 is used for storing historical position information of the transmitting terminal.
For example, the storage unit stores the position information obtained by the transmitting terminal through the global navigation satellite system, and when the GNSS signal is lost and the position information of the transmitting terminal cannot be obtained, the position information stored in the storage unit is the historical position information of the transmitting terminal.
(2) Acquisition unit 302
An obtaining unit 302, configured to obtain location loading data according to the historical location information, and load the location loading data into side link control information.
For example, when the vehicle as the transmitting end travels in a tunnel or on a street congested in a city center, where the traveling speed of the vehicle is not high, especially on a congested road, the speed of the vehicle is low, the obtaining unit multiplexes the last past location information of the transmitting end as location loading data, and loads the location loading data into the second-stage sidelink control information.
When the vehicle serving as the transmitting end runs on the expressway and the running direction and speed of the vehicle are regular, the acquiring unit further comprises a calculating unit for calculating the position offset of the transmitting end and calculating the position loading data according to the position offset and the stored historical position information.
(3) Transmission unit 303
A transmitting unit 303, configured to transmit the sidelink control information to a receiving end.
For example, the transmission unit transmits second-level sidelink control information including location loading data of a transmitting end to a receiving end.
In order to better implement the above method, the embodiment of the present invention may further provide another communication distance calculating apparatus, which may be specifically integrated in a network device, where the network device may be a terminal or the like.
For example, as shown in fig. 4, the communication distance calculation apparatus may include a receiving unit 401, an obtaining unit 402, as follows:
(1) receiving unit 401
A receiving unit 401, configured to receive historical location information of a transmitting end.
For example, the position information of the transmitting end is loaded into the second-level sidelink control information, and the receiving unit receives the second-level sidelink control information transmitted by the transmitting end, that is, the position information of the transmitting end. The receiving end stores the position information of the transmitting end.
(2) Acquisition unit 402
An obtaining unit 402, configured to obtain location loading data of the transmitting end according to the historical location information.
For example, when a vehicle as a transmitting end is congested, the acquisition unit loads the last transmitting end history position information stored in the multiplexing receiving end as position loading data.
When the vehicle serving as the transmitting terminal runs on the expressway and the running direction and speed of the vehicle are regular, the acquisition unit receives the position offset transmitted by the transmitting terminal, and calculates the position loading data of the transmitting terminal according to the position offset and the historical position information of the transmitting terminal stored in the position offset.
Under the condition that the transmitting terminal cannot acquire the position information of the transmitting terminal through the GNSS, the distance from the transmitting terminal to the receiving terminal is calculated through the operation of the transmitting terminal and the receiving terminal in the communication distance calculation method in the embodiment of the invention. The distance from the transmitting end to the receiving end calculated by the scheme can be applied to vehicle formation driving cases in the vehicle wireless communication technology, and the calculated distance from the transmitting end to the receiving end is compared with the communication distance requirement, so that whether HARQ feedback is carried out or not is judged.
In a vehicle formation driving case in the vehicular wireless communication technology, group propagation is introduced, and when HARQ feedback is enabled for the group propagation, the TX-RX (transmitting end-receiving end) distance and/or reference signal received power are/is used for deciding whether to send the HARQ feedback. The group-propagated HARQ feedback supports two options: option 1: if the receiving end UE fails to decode the corresponding Transport Block (TB) after decoding the related Physical Sidelink Control Channel (PSCCH), HARQ-NACK (NACK: non-acknowledgement) is transmitted on a Physical Sidelink Feedback Channel (PSFCH), and the decoding fails. Otherwise no signal is sent on the PSFCH. Option 2: and if the receiving end UE successfully decodes the corresponding TB, transmitting HARQ-ACK (ACK: acknowledgement) on the PSFCH. After decoding the relevant PSCCH targeted to the receiver UE, HARQ-NACK is transmitted on the PSFCH if the corresponding TB cannot be successfully decoded. If the TX-RX distance is less than or equal to a communication distance requirement (communication distance requirement), the UE transmits HARQ feedback for the physical side link shared channel, otherwise, the UE does not transmit the HARQ feedback. And the above-mentioned communication distance requirement can be obtained by decoding SCI (Sidelink control information). The distance between the receiving end and the transmitting end is calculated by the receiving end, and the position information of the transmitting end is carried by the second stage SCI (2nd stage SCI). At this time, the position information of the default transmitting end is available and is transmitted to the receiving end through the second-level SCI for calculation. If the position information of the transmitting terminal cannot be obtained at this time, the communication distance calculation method provided by the embodiment of the invention is suitable for the situation at this time.
Accordingly, an embodiment of the present invention further provides a terminal, as shown in fig. 5, the terminal may include a Radio Frequency (RF) circuit 501, a memory 502 including one or more computer-readable storage media, an input unit 503, a display unit 504, a sensor 505, an audio circuit 506, a Wireless Fidelity (WiFi) module 507, a processor 508 including one or more processing cores, and a power supply 509. Those skilled in the art will appreciate that the terminal structure shown in fig. 5 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components. Wherein:
