detailed description

In order to make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

The communication systems and business scenarios described in the embodiments of this application are intended to more clearly illustrate the technical solutions of the embodiments of this application, and do not constitute a limitation to the technical solutions provided in the embodiments of this application. Those of ordinary skill in the art will know that with the communication system With the evolution of and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

FIG. 1 shows a block diagram of a communication system supporting direct communication provided by an exemplary embodiment of the present application. The communication system may include: an access network 12 and a terminal 13.

The access network 12 includes several access network devices 120. The access network device 120 may be a base station, which is a device deployed in an access network to provide a wireless communication function for a terminal. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, and so on. In systems using different wireless access technologies, the names of devices with base station functions may be different. For example, in LTE systems, they are called eNodeB or eNB; in 5G NR systems, they are called gNodeB or gNB. With the evolution of communication technology, the name "base station" may be described and will change. For convenience, in the embodiments of the present application, the above-mentioned devices providing wireless communication functions for terminals are collectively referred to as access network equipment.

The terminal 13 may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, as well as various forms of terminal (User Equipment, UE), and mobile stations (Mobile Station). Station, MS), terminal (terminal device), etc. For ease of description, the devices mentioned above are collectively referred to as terminals. The access network device 120 and the terminal 13 communicate with each other through a certain air interface technology, such as a Uu interface.

In the embodiment of the present application, the terminal 13 includes: a vehicle 131, other vehicles 132, infrastructure 133 and pedestrians 134.

Vehicle to Vehicle (Vehicle to Vehicle, V2V) refers to the communication between the vehicle 131 and other vehicles 132. The own vehicle sends its own related information to the other vehicle. The related information includes driving speed, geographic location, driving direction and driving Status, etc.

Vehicle to Infrastructure (V2I) refers to the communication between the vehicle 131 and the infrastructure 133. The infrastructure 133 includes all the infrastructure encountered during the driving of the vehicle, including traffic lights, bus stops, buildings, tunnels and other buildings facility.

Vehicle to Pedestrian (V2P) refers to the communication between the vehicle 131 and the pedestrian 134. Pedestrian generally refers to electronic devices with mobile communication capabilities carried by pedestrians, such as mobile phones and wearable devices. Among them, wearable devices include smart bracelets, smart watches, and smart rings.

In the embodiment of this application, the vehicle 131 is referred to as the first terminal, and the other vehicles 14, the infrastructure 133, and the pedestrian 134 are referred to as the second terminal for illustration, but the two can also exchange roles, which is not limited. .

Optionally, both the first terminal and the second terminal are terminals that support direct communication, and the communication system may be an NR system and a subsequent evolution system.

The V2X direct communication in LTE can only support some basic security V2X applications, such as the exchange of basic security messages (BSM-Basic Safety Message) such as CAM (Cooperative Awareness Messages) or DENM (Decentralized Environmental Notification Message). With the recent development of technologies such as autonomous driving, in order to support new V2X services, new requirements have been put forward for the performance of V2X technology. The use of 5G NR (New Radio) technology to support new V2X communication services and scenarios has become an important content. Related technologies have established some new business requirements that need to be met by V2x communication, including vehicle fleet management (Vehicles Platooning), extended sensors, advanced driving (Advanced Driving), and remote driving (remote driving). In general, NR V2X direct communication needs to provide a higher communication rate, shorter communication delay, and more reliable communication quality.

In the discussion of NR V2X, RAN1 decided to support the configuration of some parameters or functions of direct communication through pre-configuration and/or configuration methods, such as the waveform used for direct communication , The time interval between data transmission and the corresponding feedback information transmission, whether to enable HARQ feedback for unicast direct communication, whether to enable HARQ feedback for multicast direct communication, and whether to enable power control for unicast communication, etc. .

In LTE V2X, pre-configuration and/or configuration methods are also supported to configure some parameters of direct communication. "Pre-configuration" refers to: pre-configured in the terminal, when the terminal is outside the coverage of the cellular network base station, it can use the pre-configured direct communication parameters for direct communication; and "configuration" refers to the base station by sending downlink RRC signaling provides direct connection communication parameters to the terminal, which is only valid when the terminal is within the coverage of the cellular network. When the terminal is within the coverage of the cellular network and has both pre-configured and configured two sets of inconsistent direct communication parameters, the terminal preferentially selects the direct communication parameters configured by the base station.

In LTE V2X, it is assumed that the pre-configuration/configuration information of all terminals are the same (guaranteed by the operator in actual operation), and there will be no conflicts with each other.

In NR V2X, the pre-configured/configured direct communication parameters include the need to indicate whether to use HARQ feedback in direct unicast and/or multicast communication, and whether to use the power control function in unicast direct communication. But the same terminal may have multiple unicast and/or multicast services at the same time. For some unicast and multicast services (such as services with high reliability requirements), HARQ feedback may be more advantageous; for other unicast and multicast services (such as relatively high delay requirements), the reliability requirements are relatively low. It may be more advantageous not to perform HARQ feedback. On the other hand, the interference environment of wireless transmission will also affect whether to use HARQ. When the density of the terminal is relatively high and the amount of data is relatively large, the interference between signals may be high, and the reliability of HARQ feedback may not be guaranteed. In this case, HARQ feedback is not required; otherwise, it is more advantageous to use HARQ feedback. For power control, there is a similar situation: when the relative speed between users is relatively high, because the distance between users changes quickly, power control tends not to be applied. Therefore, it is necessary to design a more flexible mechanism to determine whether HARQ feedback is required for a given unicast or multicast service; and whether power control is required for a given unicast service.

In addition, direct unicast communication occurs between two terminals, and direct multicast communication occurs between multiple terminals.

If the pre-configuration/configuration information of the transmitting-side terminal and the receiving-side terminal are inconsistent, the perception of whether to enable HARQ feedback or whether to perform power control is inconsistent, not only will cause the HARQ process or power control to fail, but also incorrect HARQ feedback or power control It will cause data transmission failure or reduced efficiency. Unlike LTE V2X which mainly supports basic car networking services, NR V2X needs to support rich car networking services including autonomous driving. Different terminals mainly target different types of services and their own device capabilities, so they may be configured or pre-configured with different HARQ feedback and power control enabling conditions.

In the embodiments of this application, it supports different unicast and multicast services on the same terminal, which can independently enable or disable HARQ feedback and power control; it also supports pre-configuration/configuration of different terminals to enable HARQ and enable power control .

Fig. 2 shows a flowchart of a method for determining parameters of direct communication provided by an exemplary embodiment of the present application. The method can be applied to the communication system as shown in Fig. 1, and the method includes:

Step 201: The first terminal obtains the first continuous communication parameter;

Step 206: The second terminal sends second signaling to the first terminal, the second signaling carries the third direct communication parameter

Step 207: The first terminal receives second signaling sent by the second terminal, where the second signaling carries the third direct communication parameter;

Wherein, the third direct communication parameter is determined according to the first direct communication parameter and the second direct communication parameter.

Step 208: The first terminal and the second terminal determine the third direct connection communication parameter as an enabled direct connection communication parameter.

In summary, in the method provided in this embodiment, the first terminal and the second terminal negotiate the direct communication parameters required for direct communication, so that the first terminal and the second terminal are configured with different direct communication In the parameter scenario, the two terminals can determine the third direct communication parameter through negotiation, and then use the third direct communication parameter to perform direct communication. This application supports that different unicast and multicast services on the same terminal can independently enable or disable HARQ feedback and power control, and supports pre-configuration/configuration of different enabling HARQ and enable power control on different terminals.

IfEnableHARQEnumerated{enable,disable}; among them, enable represents enabling HARQ feedback, and disable represents disabling HARQ feedback.

For another example, configuring binary parameter identification for unicast or multicast respectively whether to perform HARQ feedback:

IfEnableHARQUnicast Enumerated{enable,disable}; among them, enable represents enabling HARQ feedback for unicast direct communication, and disable represents disabling HARQ feedback for unicast direct communication.

ListQoSHARQ={QoS1Enumerated{enable,disable};

QoS2Enumerated{enable,disable};

…}

In summary, in the method provided in this embodiment, the base station configures the direct communication parameters for different terminals according to the division conditions. The direct communication parameters of all or some terminals are different, so that the terminals in different car networking scenarios can be Use different direct communication parameters.

In an alternative embodiment based on FIG. 3, the above-mentioned dividing conditions are configured with different priorities, and the direct communication parameters configured according to the high priority can cover the direct communication parameters configured according to the low priority. The "override" here includes: retaining the direct communication parameters configured with high priority and deleting the direct communication parameters configured with low priority; or, enabling the direct communication parameters configured with high priority and disabling low priority. Configured direct communication parameters.

In an illustrative example, the first division condition of high priority includes: cell, geographic area, terminal; the second division condition of low priority includes: source address and/or destination address of direct communication, QoS level, and At least one of the priorities.

For example, the base station first configures a set of direct communication parameters for the terminal according to the cell as a dividing condition, and then configures another set of direct communication parameters for the terminal according to the QoS level. Since the priority of the QoS level is higher than the priority of the cell, the latter One set of direct communication parameters will overwrite the previous set of direct communication parameters.

Fig. 4 is a flowchart of a method for determining parameters of direct communication provided by another embodiment of the present application. This method can be executed by the communication system shown in FIG. 1. The method includes:

Step 401: The base station determines the first continuous communication parameter of the first terminal according to the first division condition;

The first division condition includes: at least one of a cell, a geographic area, a terminal, a source address and/or a destination address of direct communication, a QoS level, and a priority.

Step 402: The base station pre-configures and/or configures the first continuous communication parameter to the first terminal;

The base station pre-configures and/or configures the first terminal through downlink control signaling broadcast by the cell (such as a system broadcast message, etc.), or through downlink control signaling dedicated to the first terminal.

Step 403: The first terminal receives the first continuous communication parameter configured by the base station;

Step 404: The base station determines the second direct communication parameter of the second terminal according to the first division condition;

Optionally, the first division condition adopted by the base station for the first terminal and the second terminal may be the same or different. Even if the same first division condition is used, the first direct communication parameter and the second direct communication parameter may be different.

Step 405: The base station preconfigures and/or configures second direct communication parameters for the second terminal;

The base station pre-configures and/or configures the second terminal through downlink control signaling (such as system broadcast messages, etc.) broadcast by the cell, or through downlink control signaling dedicated to the second terminal.

Step 406: The second terminal receives the second direct communication parameter configured by the base station.

During or after the unicast (and/or multicast) establishment of the direct communication, the first terminal and the second terminal need to negotiate and confirm the direct communication parameters of this direct communication. Among them, one of the first terminal and the second terminal is a transmitting-side terminal, and the other is a receiving-side terminal.

For the sender and receiver terminals of unicast direct communication, it is necessary to agree on whether to enable HARQ feedback and/or power control; for the sender and receiver terminals of multicast direct communication, some receivers can be allowed The terminal enables HARQ feedback, and another part of the receiving side terminal disables HARQ feedback.

The access layer (AS-Access Stratum) protocol stack of direct communication is shown in Figure 5. If the establishment process of the direct communication is completed by the non-access layer (that is, a higher layer, such as the application layer), then after the direct communication is established, the sending-side terminal and the receiving-side terminal need to negotiate the direct communication parameters. This process can be initiated by the sending-side terminal or the receiving-side terminal. That is, the first terminal may be a transmitting-side terminal or a receiving-side terminal.

If the establishment process of the direct communication is completed by the access layer, then in the establishment process of the direct communication, the direct communication parameters need to be negotiated between the sending-side terminal and the receiving-side terminal.

Optionally, the first signaling may also be referred to as: first negotiation signaling, or first direct communication parameter negotiation signaling and other names.

Optionally, the first signaling further carries other parameters related to the negotiation process, and the other parameters include: at least one of channel congestion, speed of the first terminal, Qos level, reliability, and priority. At this time, the third direct communication parameter is determined based on the first direct communication parameter, the second direct communication parameter and other parameters.

When the target parameter is a parameter configured as enabled in the first direct communication parameter and the second direct communication parameter, and when the channel congestion is lower than a certain threshold, The target parameter is determined as the third direct communication parameter.

Illustratively, other parameters include: speed, when the target parameter is a parameter configured to be enabled in the first direct communication parameter and the second direct communication parameter, and when the speed is lower than a certain threshold, the target parameter is determined It is the third direct communication parameter.

Illustratively, other parameters include: QoS level. When the target parameter is a parameter configured as enabled in the first direct communication parameter and the second direct communication parameter, and when the QoS level is higher than a certain threshold, the target The parameter is determined as the third direct communication parameter.

Illustratively, other parameters include: reliability. When the target parameter is a parameter configured as enabled in the first direct communication parameter and the second direct communication parameter, and when the reliability is higher than a certain threshold, the target The parameter is determined as the third direct communication parameter.

Illustratively, other parameters include: reliability. When the target parameter is a parameter configured as enabled in the first direct communication parameter and the second direct communication parameter, and the priority is higher than a certain threshold, the target The parameter is determined as the third direct communication parameter.

Optionally, the foregoing thresholds are pre-configured or configured, and the foregoing thresholds may also be predefined by the communication protocol.

Step 414: The base station pre-configures and/or configures the fourth direct communication parameter to the first terminal;

Step 415: The first terminal receives the fourth direct communication parameter configured by the base station according to the second division condition;

Step 416: The first terminal determines the enabled direct communication parameter according to the fourth direct communication parameter.

Step 417: The base station determines the fifth direct communication parameter of the second terminal according to the second division condition;

Even if a different second division condition is adopted, the fourth direct communication parameter and the fifth direct communication parameter need to be the same, so that the first terminal and the second terminal can determine the enabled direct communication parameters without negotiation.

The high-priority division condition can also be used in combination with the low-priority division condition. If the terminal has been configured by the low-priority division condition, the configuration in the high-priority division condition can be overwritten in the low-priority division condition Configuration. For example, a low-priority division condition is used to configure a terminal to not use HARQ feedback, but a high-priority division condition can be used to configure the unicast/multicast communication configuration of a specific source and destination address pair on the terminal To use HARQ feedback for transmission; and other unicast/multicast communications on the terminal that are not configured by the high-priority division condition still do not use HARQ feedback for transmission.
