Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Fig. 1 is a block diagram illustrating a communication system supporting direct communication according to an exemplary embodiment of the present application, where the communication system may include: an access network 12 and a terminal 13.

Several access network devices 120 are included in access network 12. The access network equipment 120 may be a base station, which is a device deployed in an access network to provide wireless communication functions for terminals. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different radio access technologies, the names of devices with base station functionality may differ, for example in LTE systems, called eNodeB or eNB; in the 5G NR system, it is called a gbnodeb or a gNB. The name "base station" may describe, and may vary as communication technology evolves. In this embodiment, the apparatus for providing a wireless communication function for a terminal is collectively referred to as an access network device.

The terminal 13 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem having wireless communication functions, as well as various forms of terminals (UE), Mobile Stations (MS), terminal (terminal device), and the like. For convenience of description, the above-mentioned devices are collectively referred to as a terminal. The access network device 120 and the terminal 13 communicate with each other through some air interface technology, for example, a Uu interface.

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

Vehicle-to-Vehicle (V2V) refers to communication between the Vehicle 131 and another Vehicle 132, and the Vehicle transmits the own Vehicle's own related information including the traveling speed, geographical position, traveling direction, traveling state, and the like to the other Vehicle.

Vehicle to Infrastructure (V2I) refers to communication between the Vehicle 131 and the Infrastructure 133, and the Infrastructure 133 includes all the Infrastructure encountered during the travel of the Vehicle, including building facilities such as traffic lights, bus stations, buildings, and tunnels.

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

In the embodiment of the present application, the vehicle 131 is referred to as a first terminal, and the other vehicle 14, the infrastructure 133, and the pedestrian 134 are referred to as a second terminal for illustration, but the roles of the two may be interchanged, and the present invention is not limited thereto.

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

V2X direct communication in LTE can only support V2X applications with some Basic security aspects, such as exchanging Basic security information (BSM-Basic security messages) like cam (cooperative Awareness messages) or denm (centralized Environmental Notification Message). With the recent development of technologies such as autopilot, new requirements are put on the performance of the V2X technology in order to support new V2X services. Supporting New V2X communication services and scenarios using 5G NR (New Radio) technology has become an important issue. Some new service requirements that V2x communication needs to meet have been established in the related art, including fleet management (Vehicles), Extended Sensors (Extended Sensors), Advanced Driving (Advanced Driving), and remote Driving (remote Driving). Overall, the NR V2X direct communication needs to provide higher communication rate, shorter communication delay, and more reliable communication quality.

In the discussion of NR V2X, RAN1 supports the configuration of some parameters or functions of direct communication by pre-configuration and/or configuration methods, such as: a waveform (waveform) used by the direct communication, a time interval between data transmission and corresponding feedback information transmission, whether to enable HARQ feedback of unicast direct communication, whether to enable HARQ feedback of multicast direct communication, whether to enable power control of unicast communication, and the like.

Configuring some parameters of direct communication using pre-configured and/or configured methods is also supported in LTE V2X. "preconfigured" means: the method comprises the steps that the method is configured in a terminal in advance, and when the terminal is out of the coverage range of a cellular network base station, direct communication can be carried out by using pre-configured direct communication parameters; and "configuring" means: the base station provides the direct connection communication parameters for the terminal by sending downlink RRC signaling, and the direct connection communication parameters are only effective when the terminal is in the coverage range of the cellular network. When the terminal is in the coverage range of the cellular network and has two groups of inconsistent direct-connection communication parameters which are pre-configured and configured, the terminal preferentially selects the direct-connection communication parameters which are configured by the base station.

In LTE V2X, it is assumed that the preconfiguration/configuration information of all terminals is consistent (guaranteed by the operator in actual operation), and no conflict occurs between them.

In NR V2X, the preconfigured/configured direct communication parameters include: it needs to indicate whether HARQ feedback is used in direct connection unicast and/or multicast communication and whether a power control function is used in unicast direct connection communication. But multiple unicast and/or multicast services may exist for the same terminal at the same time. HARQ feedback may be more advantageous for some unicast and multicast services (e.g., services with higher reliability requirements); while it may be more advantageous not to perform HARQ feedback for other unicast and multicast services (e.g., for services with higher latency requirements and lower reliability requirements). On the other hand, the interference environment of wireless transmission also affects whether HARQ is used. When the density of the terminal is high and the data volume is large, the interference between signals is high, the reliability of HARQ feedback may not be ensured, and HARQ feedback does not need to be used; the use of HARQ feedback is more advantageous in the opposite sense. For power control, there are similar situations: when the relative speed between users is high, power control tends to be inapplicable because the distance between users changes rapidly. Therefore, a more flexible mechanism needs to be designed to decide whether HARQ feedback is needed for a given unicast or multicast service; and whether power control is required for a given unicast traffic.

In addition, direct connection unicast communication occurs between two terminals, and direct connection multicast communication occurs between a plurality of terminals.

If the preconfigured/configured information of the sending terminal and the receiving terminal are inconsistent, the HARQ process or power control cannot work for whether HARQ feedback is enabled or whether power control cognition is inconsistent, and the data transmission failure or efficiency reduction is caused by wrong HARQ feedback or power control. Unlike LTE V2X, which primarily supports basic car networking services, NR V2X needs to support rich car networking services including autonomous driving. Different terminals may be configured or preconfigured with different HARQ feedback and power control enabling scenarios because the service types and own device capabilities mainly targeted by the terminals may be different.

In the embodiment of the application, different unicast and multicast services supported on the same terminal can independently enable or disable HARQ feedback and power control; different terminals are also supported to pre-configure/configure different enabled HARQ and enabled power control.

Fig. 2 is a flowchart illustrating a method for determining parameters of direct communication according to an exemplary embodiment of the present application. The method can be applied to a communication system as shown in fig. 1, and comprises the following steps:

step 201, a first terminal acquires a first direct communication parameter;

step 202, a second terminal acquires a second direct connection communication parameter;

step 203, the first terminal sends a first signaling to the second terminal, and the first signaling carries a first direct communication signaling parameter;

step 204, the second terminal receives a first signaling sent by the first terminal;

step 205, the second terminal determines a third direct communication parameter according to the first direct communication parameter and the second direct communication parameter;

step 206, the second terminal sends a second signaling to the first terminal, and the second signaling carries a third direct connection communication parameter

Step 207, the first terminal receives a second signaling sent by the second terminal, and the second signaling carries a third direct connection communication parameter;

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

And 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 direct connection communication parameters required for direct connection communication, so that in a scenario where the first terminal and the second terminal are configured with different direct connection communication parameters, the two terminals can determine a third direct connection communication parameter through a negotiation manner, and then use the third direct connection communication parameter to perform direct connection communication. The method and the device support different unicast and multicast services on the same terminal to independently enable or disable HARQ feedback and power control, and support different enabled HARQ and enabled power control preconfigured/configured on different terminals.

It should be noted that, the above steps 201, 203, 207, and 208 may be implemented separately as a parameter determination method for direct communication on the first terminal side, and the above steps 202, 204, 205, 206, and 208 may be implemented separately as a parameter determination method for direct communication on the second terminal side.

Optionally, when there are two sets of pre-configured and configured first direct communication parameters at the same time, the configured first direct communication parameters are preferentially used.

In an alternative embodiment based on fig. 2, the second direct communication parameters comprise: whether HARQ feedback is enabled, and/or whether power control is enabled;

Optionally, when there are two sets of pre-configured and configured second direct communication parameters at the same time, the configured second direct communication parameters are preferentially used.

In an alternative embodiment based on fig. 2, the first signaling and the second signaling are RRC layer signaling, or MAC layer signaling, or physical layer signaling.

In an alternative embodiment based on fig. 2, the first direct communication parameter and the second direct communication parameter are the same or different direct communication parameters. The method comprises the steps that the base station pre-configures and/or configures direct communication parameters to the terminal.

Fig. 3 is a flowchart illustrating a method for determining parameters of direct communication according to an exemplary embodiment of the present application. The method can be applied to the communication system as shown in fig. 1, and comprises the following steps:

IfEnableHARQ managed { enable, disable }; wherein enable represents enabling the HARQ feedback, and disable represents not enabling the HARQ feedback.

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

IfEnableHARQUnicast Enumerated { enable, disable }; wherein enable represents enabling HARQ feedback for the unicast direct connection message, and disable represents not enabling HARQ feedback for the unicast direct connection message.

IfEnableHARQ multicast managed { enable, disable }; wherein enable represents that the HARQ feedback can be enabled for the multicast direct connection message, and disable represents that the HARQ feedback cannot be enabled for the multicast direct connection message.

Here, the "enabled, disabled" parameter may take one of two values, enabled or disabled.

For another example, configuring a destination address list destaddrenabler HARQ capable of enabling HARQ feedback for the terminal;

DestAddrEnableHARQ＝{Dest1，Dest2，…}；

as another example, the terminal is configured with a list of whether HARQ is enabled or not corresponding to different QoS classes:

ListQoSHARQ＝{QoS1Enumerated{enable,disable}；

QoS2Enumerated{enable,disable}；

…}

step 303, the terminal receives the direct connection communication parameters preconfigured and/or configured by the base station according to the dividing conditions.

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

In an alternative embodiment based on fig. 3, the above-mentioned dividing conditions are configured with different priorities, and the direct connection communication parameters configured according to a high priority may be covered with the direct connection communication parameters configured according to a low priority. "covering" here includes: reserving the direct connection communication parameters configured with high priority, and deleting the direct connection communication parameters configured with low priority; or enabling the direct connection communication parameters configured with high priority and enabling the direct connection communication parameters configured with low priority.

In one illustrative example, the high priority first partitioning condition includes: cell, geographical range, terminal; the second division condition of the low priority includes: at least one of a source and/or destination address, QoS class and priority of the direct communication.

For example, the base station configures a group of direct communication parameters to the terminal according to the cell as a division condition, and then configures another group of direct communication parameters to the terminal according to the QoS class, and since the priority of the QoS class is higher than that of the cell, the latter group of direct communication parameters covers the former group of direct communication parameters.

Fig. 4 is a flowchart of a method for determining parameters of direct communication according to another embodiment of the present application. The method may be performed by the communication system shown in fig. 1. The method comprises the following steps:

step 401, the base station determines a first direct communication parameter of the first terminal according to a first division condition;

the first division condition includes: at least one of a cell, a geographical range, a terminal, a source and/or destination address for direct communication, a QoS level and a priority.

Step 402, the base station pre-configures and/or configures first direct communication parameters to the first terminal;

the base station performs pre-configuration and/or configuration on the first terminal through downlink control signaling (such as system broadcast message) broadcast by the cell or through downlink control signaling dedicated to the first terminal.

Step 403, the first terminal receives a first direct communication parameter configured by the base station;

step 404, the base station determines a second direct communication parameter of the second terminal according to the first division condition;

Alternatively, the first division condition employed by the base station for the first terminal and the second terminal may be the same or different. The first direct communication parameter and the second direct communication parameter may be different even if the same first division condition is employed.

Step 405, the base station pre-configures and/or configures second direct connection communication parameters to a second terminal;

the base station performs pre-configuration and/or configuration on the second terminal through downlink control signaling (such as system broadcast message) broadcast by the cell or through downlink control signaling dedicated to the second terminal.

Step 406, the second terminal receives a second direct communication parameter configured by the base station;

optionally, the configuration processes in steps 401 to 403 and the configuration processes in steps 404 to 406 are independent from each other, and the execution order of the two configuration processes is not limited, and the two configuration processes may be executed simultaneously, or one of the configuration processes may be executed first and then the other configuration process may be executed.

Optionally, the base station in steps 401 to 403 and the base station in steps 404 to 406 are the same base station, or may be two different base stations.

At this time, the first terminal and the second terminal have respective direct communication parameters.

Step 407, the first terminal sends a first signaling to the second terminal, and the first signaling carries a first direct communication signaling parameter;

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 direct communication parameters of the direct communication. One of the first terminal and the second terminal is a transmitting terminal, and the other terminal is a receiving terminal.

For a sending side terminal and a receiving side terminal of unicast direct communication, whether HARQ feedback and/or power control are enabled needs to be agreed; for the terminals on the transmitting side and the terminals on the receiving side of the multicast direct communication, a part of the terminals on the receiving side may be allowed to enable the HARQ feedback, and another part of the terminals on the receiving side may be allowed to disable the HARQ feedback.

The Access Stratum (AS-Access Stratum) protocol stack for direct communication is shown in fig. 5. If the establishment procedure of the direct communication is performed by a non-access stratum (i.e. a higher layer, such as an application layer), after the establishment of the direct communication, the terminal on the transmitting side and the terminal on the receiving side need to negotiate direct communication parameters. The process may be initiated by the terminal on the transmitting side or may be initiated by the terminal on the receiving side. 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, the terminal at the sending side and the terminal at the receiving side need to negotiate the direct communication parameters in the establishment process of the direct communication.

Optionally, the first signaling may also be referred to as: first negotiation signaling, or first direct communication signaling parameter negotiation signaling, etc. The first signaling includes: the first terminal is configured or preconfigured with whether HARQ feedback is enabled and/or whether configuration of power control is enabled.

Step 408, the second terminal receives the first signaling sent by the first terminal;

step 409, the second terminal determines a third direct connection communication parameter according to the first direct connection communication parameter and the second direct connection communication parameter;

and the second terminal determines a third direct communication parameter at least according to the first direct communication parameter and the second direct communication parameter. Optionally, the third direct communication parameter includes: the first direct communication parameter and the second direct communication parameter are both configured to be the same type of enabled (enable) parameter. For example, for unicast direct communication, when both the first direct communication parameter and the second direct communication parameter are set to enable HARQ states, setting the unicast direct communication to enable HARQ states and determining the HARQ states as one of the third direct communication parameters.

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

Illustratively, other parameters include: and determining the target parameter as a third direct connection communication parameter when the target parameter is a parameter configured to be enabled in both the first direct connection communication parameter and the second direct connection communication parameter and the channel congestion condition is lower than a certain threshold value.

Illustratively, other parameters include: and the speed is used for determining the target parameter as a third direct connection communication parameter when the target parameter is a parameter which is configured to be enabled in the first direct connection communication parameter and the second direct connection communication parameter and the speed is lower than a certain threshold value.

Illustratively, other parameters include: and the QoS grade is used for determining the target parameter as a third direct connection communication parameter when the target parameter is a parameter which is configured to be enabled in the first direct connection communication parameter and the second direct connection communication parameter and the QoS grade is higher than a certain threshold value.

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

Illustratively, other parameters include: and reliability, when the target parameter is a parameter configured to be enabled in both the first direct communication parameter and the second direct communication parameter, and when the priority is higher than a certain threshold, determining the target parameter as a third direct communication parameter.

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

Step 410, the second terminal sends a second signaling to the first terminal, and the second signaling carries a third direct connection communication parameter;

step 411, the first terminal receives a second signaling sent by the second terminal, and the second signaling carries a third direct connection communication parameter;

Step 412, the first terminal and the second terminal determine enabled direct communication parameters according to the third direct communication parameters;

step 413, the base station determines a fourth direct communication parameter of the first terminal according to the second division condition;

the second division condition includes: at least one of a cell, a geographical range, a terminal, a source and/or destination address of a direct communication, a QoS level of a direct communication and a priority of a direct communication.

Optionally, the second division condition and the first division condition are different. Optionally, the second division condition has a higher priority than the first division condition. .

Step 414, the base station pre-configures and/or configures fourth direct communication parameters to the first terminal;

step 415, the first terminal receives a fourth direct communication parameter configured by the base station according to the second division condition;

and step 416, the first terminal determines enabled direct connection communication parameters according to the fourth direct connection communication parameters.

The fourth direct communication parameter configured according to the second division condition covers the first direct communication parameter configured according to the first division condition.

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

the second division condition includes: at least one of a cell, a geographical range, a terminal, a source and/or destination address for direct communication, a QoS level and a priority.

Optionally, the second division condition and the first division condition are different. Optionally, the priority of the second division condition is higher than the priority of the second division condition.

Step 418, the base station pre-configures and/or configures fifth direct connection communication parameters to the second terminal;

step 419, the second terminal receives a fifth direct connection communication parameter configured by the base station according to the second division condition;

and step 420, the second terminal determines enabled direct connection communication parameters according to the fifth direct connection communication parameters.

The fifth direct communication parameter configured according to the second division condition will override the second direct communication parameter configured according to the first division condition.

Alternatively, the second division condition adopted by the base station for the first terminal and the second terminal may be the same or different. Even if different second partition conditions are 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 partitioning condition may also be used in combination with the low-priority partitioning condition, and if the terminal has already been configured by the low-priority partitioning condition, the configuration in the high-priority partitioning condition may overwrite the configuration in the low-priority partitioning condition. For example, a low-priority partition condition is used to configure a certain terminal not to use HARQ feedback, but a high-priority partition condition may be used to configure unicast/multicast communication of a certain source and target address pair on the terminal to use HARQ feedback for transmission; while other unicast/multicast communications on the terminal that are not configured by the high priority partitioning condition still do not use HARQ feedback for transmission.

601, the base station determines a fourth direct communication parameter of the first terminal according to the second division condition;

the second division condition includes: at least one of a source address and/or a destination address of the direct communication, a QoS level of the direct communication, and a priority of the direct communication.

For example, the base station configures a fourth direct communication parameter to the first terminal according to a source address and a destination address of the direct communication.

Step 602, the base station pre-configures and/or configures fourth direct communication parameters to the first terminal;

step 603, the first terminal receives a fourth direct communication parameter configured by the base station according to the second division condition;

step 604, the first terminal determines enabled direct communication parameters according to the fourth direct communication parameters.

Step 605, the base station determines a fifth direct communication parameter of the second terminal according to the second division condition;

the second division condition includes: at least one of a source and/or destination address, QoS class and priority of the direct communication.
