[0038] Specifically, embodiments of the present invention provide a communication method, apparatus, base station, and terminal, which solve the problem of how to implement V2X communication in scenarios where Uu-only terminals coexist with other types of terminals.

[0039] First Embodiment

[0040] like Figure 1 As shown, an embodiment of the present invention provides a communication method applied to a first base station, specifically including the following steps:

[0041] S11, obtain the first information related to vehicle networking services.

[0042] Here, the first information is information related to vehicle networking services. In some optional embodiments, the first information may specifically be road safety-related information or terminal security information.

[0043] It should be noted that the first information obtained by the first base station does not need to be forwarded to the core network.

[0044] S12, Based on the first information, determine the target information related to the terminal.

[0045] S13, send the target information according to the interface communication method corresponding to the terminal and / or the type of the target information;

[0046] The interface communication methods include Uu communication and / or direct communication interface PC5 communication.

[0047] Here, terminals that only support Uu communication are called Uu-only terminals, terminals that support both Uu and PC5 communication are called Uu+PC5 terminals, and terminals that only support PC5 communication are called PC5-only terminals.

[0048] In this embodiment, the first base station acquires first information related to vehicle-to-everything (V2X) services, determines target information related to the terminal based on the first information, and then sends the target information according to the interface communication method corresponding to the terminal and / or the type of the target information. Thus, the communication method of this embodiment is applicable to terminals supporting different interface communication methods, enabling V2X communication in scenarios where Uu-only terminals coexist with other types of terminals.

[0049] Optionally, the first information is obtained through at least one of the following methods:

[0050] Acquired through sensing devices;

[0051] Obtained by one or more second base stations adjacent to the first base station;

[0052] Obtained through one or more roadside units (RSUs) within the coverage area of ​​the first base station;

[0053] Obtained through network devices;

[0054] Receive vehicle-to-everything (V2X) information sent by the terminal via the Uu interface;

[0055] Receive V2X information sent by the terminal through the PC5 interface;

[0056] Receive Radio Resource Control (RRC) signaling sent by the terminal.

[0057] It should be noted that the base station can acquire the first information simultaneously through multiple channels mentioned above. Sensing devices include cameras, radar, and various sensors; acquiring the first information through network devices can specifically involve obtaining it from a cloud platform deployed on the network device; RRC signaling can specifically include auxiliary information (assist info) sent by the terminal. Furthermore, the V2X information received by the first base station from the terminal includes at least security information; that is, the first base station can receive security information reported by the terminal through different types of interfaces (Uu interface, PC5 interface).

[0058] Optionally, the V2X information includes at least one of the following:

[0059] Geographic location information;

[0060] The vehicle model information of the first vehicle where the terminal is located;

[0061] The status information of the first vehicle includes one or more of the following: speed, acceleration, angular velocity, and driving direction information;

[0062] Destination information;

[0063] Driving intention information;

[0064] Confidence information regarding the location of the first vehicle.

[0065] Here, vehicle type information may specifically include information such as the length and width of the first vehicle; the status information of the first vehicle can also be understood as the movement status information of the terminal, which may specifically include information such as the terminal's speed (i.e., movement speed), acceleration, angular velocity, and driving direction; driving intention information may specifically include information such as lane change and U-turn.

[0066] Optionally, the RRC signaling includes at least one of the following:

[0067] The terminal's positioning capability information;

[0068] The receiving capability information of the terminal;

[0069] The terminal's service cycle information;

[0070] The service size information of the terminal.

[0071] It should be noted that for terminals that establish an RRC connection with the first base station, a soft handover method is adopted to ensure that the terminal does not experience service interruption during the handover process, which can reduce handover latency.

[0072] Optionally, determining the target information related to the terminal based on the first information includes at least one of the following:

[0073] (1) Based on the first information, determine whether there is a safety hazard in the first vehicle where the terminal is located, and generate warning information if it is determined that there is a safety hazard in the first vehicle, and determine the warning information as the target information.

[0074] It should be noted that the terminal here can be any terminal mentioned in the first information. For example, it can be a terminal on a vehicle that is affected by other vehicles and has a safety hazard, a terminal on a vehicle that causes a safety hazard to other vehicles, or a terminal on a vehicle that is affected by the road and has a safety hazard.

[0075] Here, the first base station supports vehicle-to-vehicle (V2V) communication safety judgment dynamic messages. Based on the first information, when a safety hazard is determined, an early warning message is generated and then sent out through an appropriate port. This can effectively reduce downlink load.

[0076] (2) Based on the first information, determine the effective scope of the first information, and if the effective scope of the first information is determined to be a neighboring cell, determine the security-related message corresponding to the neighboring cell in the first information as the target information, wherein the neighboring cell is the adjacent cell of the cell in the first base station.

[0077] It should be noted that the effective cell corresponding to the first information can be determined based on the scope of the first information and the coverage area of ​​the cell. The effective cell may be the current cell (i.e., the cell within the first base station) or one or more neighboring cells of the current cell. In particular, if the first information is an environmental security message, the effective scope of the first information is directly determined to be the coverage area of ​​the current cell or the current base station (i.e., the first base station).

[0078] Here, if it is determined that the terminal belongs to a user in a neighboring cell, the terminal's relevant information (security-related messages in the first information) needs to be forwarded to the base station of the neighboring cell via X2, based on the terminal's context information.

[0079] For example, the terminal security information received by the first base station through the Uu port can be used to determine whether the terminal belongs to a user in a neighboring cell based on the terminal's mobile context information.

[0080] (3) Based on the V2X information sent by the terminal, determine the neighboring cell that the first vehicle will enter, and determine the security-related message corresponding to the neighboring cell in the first information as the target information.

[0081] It should be noted that the first base station can obtain the predicted handover cell, which is the neighboring cell that the terminal may switch to, based on the V2X information reported by the terminal (including movement trajectory, speed, and acceleration, etc.) through trajectory prediction and fuzzy judgment algorithms. In vehicular network services, the terminal moves with the vehicle, and the predicted handover cell is the neighboring cell that the terminal is located in when the first vehicle will enter.

[0082] It should also be noted that different terminals may have different positioning capabilities when making fuzzy judgments, and different positioning capabilities correspond to different fuzzy judgment thresholds. Under the condition that the threshold is met, the first base station can send the terminal's historical trajectory information, security information, etc., within a certain period of time to the predicted handover cell in advance through the X2 interface.

[0083] (4) The environmental safety messages in the first information are identified as the target information.

[0084] Here, environmental safety messages refer to road safety information related to the environment.

[0085] It should be noted that the first base station needs to store the location information of the terminals camped in the neighboring cells. This is to ensure that the historical trajectory information of the terminal can be used to make more accurate predictions and judgments about the terminal's location, and to determine whether there are any security risks between the terminal and the terminal nodes in the cell.

[0086] In this embodiment, the first base station can determine the effective communication range of the first information based on the first information obtained, and perform corresponding processing based on the port, source and type of the first information obtained to obtain target information (such as early warning information), and then send the target information to the corresponding receiving object, neighboring cell, etc.

[0087] Optionally, determining whether there is a safety hazard in the first vehicle where the terminal is located based on the first information corresponding to the terminal includes:

[0088] Based on the V2X information sent by the terminal, the geographical location information of the terminal is determined;

[0089] Based on the geographical location information, it is determined whether there is a safety hazard in the first vehicle where the terminal is located.

[0090] It should be noted that when determining whether a safety hazard exists, the first base station can make a judgment based on the specific location of each terminal, combined with the terminal's driving direction and road planning. For example, for road sections with a central median, it is not necessary to consider oncoming traffic; similarly, forward collision warnings only need to consider vehicles in the traffic flow ahead of the terminal. Furthermore, when determining a safety hazard, the first base station can also consider factors such as the slipperiness and smoothness of the road surface.

[0091] In this embodiment, the first base station can comprehensively process the terminal security information received from the PC5 interface and the terminal security information received from the Uu interface within the cell to determine whether there is a security risk, so that when a security risk is determined to exist, an early warning message can be generated and sent out.

[0092] Specifically, the first base station can determine whether there is a security risk based on the terminal security information of multiple terminals in the cell received by the Uu interface, and generate early warning information when a security risk is determined to exist, and send the corresponding early warning information out through downlink unicast;

[0093] The first base station can also determine whether there are security risks in the terminals in the cell based on the security information of the neighboring cell terminals received by the X2 interface and the security information of the terminals in the cell received by the Uu / PC5 interface. When a security risk is determined to exist, an early warning message is generated and the corresponding early warning message is sent out through an appropriate port.

[0094] In this embodiment, the first base station receives V2X information through the PC5 port and the Uu port, which can determine whether there are security risks between terminals corresponding to other communication links in the cell besides the PC5 link. It can also forward information about terminals that may pose security risks to terminal nodes outside the cell to neighboring cells through the X2 port.

[0095] In an optional example, terminal A is a Uu-only terminal, terminal B is a Uu-only terminal, terminal C is a PC5-only terminal, and terminal D is a PC5+Uu terminal. When the first base station determines whether there is a security risk, since terminal C and terminal D communicate via PC5, they can determine whether there is a security risk between each other. Therefore, the first base station needs to determine whether there is a security risk among the terminal nodes {A+B,A+C,A+D,B+C,B+D}.

[0096] Optionally, before determining whether there is a safety hazard in the first vehicle where the terminal is located based on the geographical location information, the method further includes:

[0097] The geographical location information of the terminal is corrected based on the first information corresponding to the terminal.

[0098] It should be noted that, in the above embodiments, the process of determining or correcting the terminal's geographical location information can be achieved by obtaining one or more of the following information:

[0099] Obtain the geographic location information from the V2X information reported by the terminal;

[0100] Obtain vehicle model information from the V2X information reported by the terminal, which may specifically include information such as the length and width of the first vehicle;

[0101] Obtain information such as speed, acceleration, angular velocity, and direction of travel from the V2X information reported by the terminal;

[0102] Obtain destination information from the V2X information reported by the terminal;

[0103] Obtain the confidence information of the corresponding location from the V2X information reported by the terminal;

[0104] Obtain driving intent information from the V2X information reported by the terminal, including lane change, U-turn, and other information;

[0105] Obtain the positioning capability information from the RRC signaling reported by the terminal;

[0106] Obtain the reception capability information from the RRC signaling reported by the terminal.

[0107] It should also be noted that the base station can form the context information of the terminal based on the above information; the base station can correct the location information of the terminal based on mobility and location-related information.

[0108] Optionally, sending the target information according to the interface communication method corresponding to the terminal and / or the type of the target information includes at least one of the following:

[0109] (1) When the terminal only supports the Uu communication method, the target information is sent to the terminal in unicast form through the Uu interface.

[0110] Here, the terminal only supports Uu communication mode, that is, the terminal is a Uu only terminal. After receiving the V2X information sent by the Uu only terminal through Uu uplink, the first base station can send security information related to the terminal through Uu downlink unicast.

[0111] (2) If the terminal supports the Uu communication mode and the PC5 communication mode, the target information is sent to the terminal in unicast form through the Uu interface.

[0112] Here, the terminal supports both Uu and PC5 communication modes, meaning it is a Uu+PC5 terminal. After receiving the V2X information broadcast by the Uu+PC5 terminal through the PC5 port (PC5 interface), the first base station can send security information related to the terminal via Uu downlink unicast.

[0113] (3) If the terminal only supports the PC5 communication method, the target information is sent to the terminal in unicast form through the PC5 interface.

[0114] Here, the terminal only supports the PC5 communication method, that is, the terminal is a PC5 only terminal. After receiving the V2X information broadcast by the PC5 only terminal through the PC5 port, the first base station can unicast security information related to the terminal through the PC5 port.

[0115] (4) If the type of the target information is warning information, the target information is sent to the terminal;

[0116] (5) If the type of the target information is a security-related message, the target information is sent to the base station corresponding to the neighboring cell via X2;

[0117] (6) When the type of the target information is an environmental security message, the target information is sent through one or more of the following: System Information Block (SIB), Multimedia Broadcast Multicast Service (MBMS), Multicast Broadcast Single Frequency Network (MBSFN), Single-cell point to multipoint (SC-PTM), and Multimedia Broadcast Service (MBS).

[0118] Here, for environmental safety messages, the first base station can send them out through one or more of SIB, MBMS, MBSFN, SC-PTM, and MBS (for example, the first base station broadcasts instructions to all users in the cell using a Uu SIB message), and can also broadcast environmental safety messages through the PC5 port.

[0119] It should be noted that, on the one hand, considering the mobility of the terminal (topology changes), environmental security messages need to be broadcast periodically within the effective range of the message. On the other hand, considering that such messages do not have high latency requirements, after receiving such messages, the first base station can determine whether to forward them immediately or accumulate them in a window before forwarding them, based on the specific latency requirements and message type. It can also determine different window lengths based on different latency requirements.

[0120] Here, the base station can periodically broadcast target information through the PC5 interface.

[0121] The above embodiments provide mechanisms for sending various types of messages in coexistence scenarios.

[0122] In some embodiments, the method further includes:

[0123] Upon receiving RRC signaling from the terminal, allocate a first scheduling request (SR) resource to the terminal;

[0124] Receive pulse information sent by the terminal on the first SR resource;

[0125] Allocate a first semi-static resource to the terminal.

[0126] In this embodiment, the pulse information sent by the terminal on the first SR resource can trigger the first base station to allocate initial resources to the terminal. Here, the first base station allocates semi-static resources to the terminal. This semi-static resource allocation method can reduce uplink scheduling latency.

[0127] Optionally, allocating the first semi-static resource to the terminal includes:

[0128] Based on the RRC signaling in the first information corresponding to the terminal, determine the service period and service size corresponding to the terminal;

[0129] The resource cycle and resource size of the first semi-static resource are determined based on the service cycle and service size corresponding to the terminal.

[0130] In some alternative embodiments, the first base station can schedule or reschedule semi-static resources for the terminal based on the V2X information reported by the terminal received through the Uu interface and the system load.

[0131] In this embodiment, the service cycle and service size of the terminal can be determined based on the RRC signaling sent by the terminal, and then a first semi-static resource can be allocated to the terminal according to the service cycle and service size. It is understood that when allocating semi-static resources to the terminal, the system load can also be considered for semi-static resource scheduling.

[0132] Optionally, after allocating the first semi-static resource to the terminal, the method further includes at least one of the following:

[0133] If it is detected that M consecutive uplink transmissions on the first semi-static resource are all empty packets, the first semi-static resource is released.

[0134] Based on the correlation between resource-related information and resource cycles, the second semi-static resources are reconfigured for the terminal.

[0135] In this embodiment, during resource allocation, the first base station can determine an appropriate resource cycle for the terminal based on its resource-related information (including mobility-related information, uplink system load, etc.). By controlling the terminal's resource cycle based on its mobility and system load, congestion caused by always-online devices can be controlled, preventing excessive uplink resource consumption.

[0136] Here, we will take the allocation of Uu uplink resources in a Uu-only terminal as an example for explanation:

[0137] After establishing an RRC connection, the Uu-only terminal informs the first base station terminal of its own positioning accuracy, V2X information transmission prediction cycle, and size by sending RRC signaling (which includes the terminal's positioning capability information, service cycle information, service size information, etc.).

[0138] When a Uu-only terminal needs to send V2X information, it triggers such a message by sending a pulse message on the first SR resource allocated by the first base station. After receiving the pulse message sent by the Uu-only terminal through the first SR resource, the first base station can allocate corresponding resources for it according to the previously stored context information of the Uu-only terminal. The Uu-only terminal will prioritize allocating resources for basic V2X security services.

[0139] For Uu-only terminals, it is necessary to reduce latency and system load, including uplink and downlink scheduling latency and handover latency. The first base station can adjust the appropriate semi-persistent scheduling (SPS) resource period for Uu-only terminals based on their moving speed, angular velocity, and smoothed uplink system load.

[0140] It should be noted that when the first base station detects that M consecutive uplink transmissions on the uplink semi-static resources (e.g., the first semi-static resource) allocated to the Uu-only terminal are empty packets, it indicates that the RRC connection status of the Uu-only terminal may have changed. At this time, the first semi-static resource can be released. When the first base station finds that the resource period of the first semi-static resource is inappropriate, it can also reallocate semi-static resources (e.g., the second semi-static resource) to the Uu-only terminal through PDCCH signaling and cancel the previously allocated semi-static resource. When the first base station finds that the uplink load is relatively high for a period of time and needs to reduce the V2X information transmission frequency, it can reallocate resources (e.g., the second semi-static resource) to the Uu through PDCCH and cancel the previously allocated semi-static resource.

[0141] In addition, it should be noted that the candidate resource period values ​​for semi-static resource scheduling need to be consistent with the sidelink (SL), for example: {100ms, 200ms, 300ms, 400ms, 500ms, 600ms, 700ms, 800ms, 900ms, 1000ms}.

[0142] Optionally, the resource-related information includes: uplink system load and / or the terminal's mobility-related information;

[0143] The uplink system load is a smoothed value over a time window.

[0144] The movement-related information includes one or more of velocity (movement speed), acceleration, and angular velocity;

[0145] The correlation between the resource-related information and the resource cycle includes at least one of the following:

[0146] The resource cycle is inversely proportional to the speed of the terminal;

[0147] The resource cycle is inversely proportional to the acceleration of the terminal;

[0148] The resource cycle is inversely proportional to the angular velocity of the terminal;

[0149] The resource cycle is proportional to the uplink system load.

[0150] It should be noted that the heavier the uplink system load, the lower the transmission frequency needs to be, thus requiring a longer resource cycle to be configured.

[0151] Optionally, the method further includes at least one of the following:

[0152] (1) Configure the bearer of V2X heartbeat messages as a Guaranteed Bit Rate (GBR) service;

[0153] (2) Configure the allocation and retention priority (ARP) parameters for the V2X heartbeat message bearer to have only preemption attributes;

[0154] (3) Configure the priority of the QoS Class Identifier (QCI) carried by the V2X heartbeat message as the first priority.

[0155] Here, the first priority is a priority higher than the preset level, that is, the first priority is a higher priority.

[0156] It should be noted that configuring the Quality of Service (QoS) for the V2X heartbeat message bearer as described above, and standardizing the QoS parameters for the V2X heartbeat message service bearer, is to ensure that the uplink V2X security service messages of the Uu-only terminal can be sent normally under any system load. In other words, it ensures that the Uu-only terminal can access the network to establish the corresponding DRB and send information at an appropriate period, especially ensuring that the heartbeat message can be sent out.

[0157] In this embodiment, when the system load is high, access can be guaranteed through the terminal's own high-priority attribute, or by activating the bearer preemption function for admission control. Alternatively, it can preempt resources of low-priority bearers with preemption attributes, thereby ensuring V2X heartbeat services can access. In this way, through bearer configuration, secure V2X services can be accessed and remain online in real time.

[0158] In this embodiment of the invention, for the problem of how to implement V2X communication in the coexistence scenario of Uu only terminals and other types of terminals (i.e., coexistence of PC5 only and Uu only terminals and coexistence of PC5+Uu terminals and Uu only terminals), the invention provides the sending mechanism of various messages in the coexistence scenario, as well as the scheduling and rescheduling method of semi-static resources, so as to achieve low latency and high reliability V2X communication.

[0159] Second Embodiment

[0160] like Figure 2 As shown, an embodiment of the present invention provides a communication method applied to a terminal, specifically including the following steps:

[0161] Step 21: Send V2X information through the interface communication method corresponding to the terminal;

[0162] The interface communication methods include Uu communication and / or PC5 communication.

[0163] It should be noted that different types of terminals can receive environmental security messages broadcast by base stations. Terminals can also filter and process the received information at the terminal application layer based on their own location information to obtain information related to their own security.

[0164] In this embodiment, the terminal can send V2X information through the corresponding interface communication method. The communication method of this embodiment is applicable to terminals that support different interface communication methods, and can realize V2X communication in scenarios where Uu-only terminals coexist with other types of terminals.

[0165] Optionally, the V2X information includes at least one of the following:

[0166] Geographic location information;

[0167] The vehicle model information of the first vehicle where the terminal is located;

[0168] The status information of the first vehicle includes one or more of the following: speed, acceleration, angular velocity, and driving direction information;

[0169] Destination information;

[0170] Driving intention information;

[0171] Confidence information regarding the location of the first vehicle.

[0172] Here, vehicle type information may specifically include information such as the length and width of the first vehicle; the status information of the first vehicle can also be understood as the movement status information of the terminal, which may specifically include information such as the terminal's speed (i.e., movement speed), acceleration, angular velocity, and driving direction; driving intention information may specifically include information such as lane change and U-turn.

[0173] It should be noted that Uu-only terminals need to periodically send V2X information through the Uu interface.

[0174] Optionally, sending V2X information through the interface communication method corresponding to the terminal includes at least one of the following:

[0175] (1) When the terminal only supports the Uu communication method, the V2X information is sent through the Uu interface.

[0176] It should be noted that Uu-only terminals can only send V2X information via Uu uplink. Therefore, it is necessary to ensure that Uu-only terminals can access the network, which can be achieved by configuring bearer QoS parameters on the base station side.

[0177] (2) If the terminal supports the Uu communication method and the PC5 communication method, the V2X information is broadcast through the PC5 interface.

[0178] It should be noted that for Uu+PC5 terminals, in addition to handling the broadcast of V2X information through the PC5 port, it is also necessary to maintain the RRC connection.

[0179] (3) If the terminal only supports the PC5 communication method, the V2X information is broadcast through the PC5 interface.

[0180] It should be noted that for PC5-only terminals, in addition to broadcasting V2X information through the PC5 port, after receiving periodic broadcast messages from the first base station, they also need to trigger a PC5 unicast link request to establish a PC5 unicast link with the first base station and receive security information related to themselves sent by the first base station via PC5 unicast. The first base station receives the unicast link establishment request sent by the PC5-only terminal and establishes a PC5 unicast link with it.

[0181] Optionally, the method further includes:

[0182] If an RRC connection is established with the first base station, an RRC signaling message is sent to the first base station;

[0183] The RRC signaling includes at least one of the following:

[0184] The terminal's positioning capability information;

[0185] The receiving capability information of the terminal;

[0186] The terminal's service cycle information;

[0187] The service size information of the terminal.

[0188] It should be noted that the terminal needs to determine the link with the base station based on its own port access capability type. For Uu-only terminals, the terminal only needs to maintain the RRC connection. After the RRC connection is established, the Uu-only terminal will send an RRC message. This RRC signaling (such as terminal assistant info) needs to include positioning capability information, receiving capability information, etc.

[0189] Optionally, if the terminal only supports Uu communication, the method further includes the following steps before sending V2X information:

[0190] Transmit pulse information on the first SR resource allocated by the first base station.

[0191] Here, the first SR resource can be a dedicated SR resource allocated by the first base station to the terminal. This allows the first base station to immediately associate the dedicated SR resource with the user (i.e., the terminal) upon receiving the pulse information. It should be noted that this first SR resource can be released after the first base station initially allocates resources to the terminal.

[0192] In this embodiment, the terminal can trigger the initial allocation of resources by sending pulse information on the first SR resource allocated by the first base station. After receiving the pulse information sent by the terminal on the first SR resource, the first base station will allocate semi-static resources (e.g., the first semi-static resource) to the terminal.

[0193] Optionally, after the first base station reconfigures the second semi-static resources for the terminal, the method further includes at least one of the following:

[0194] Adjust the packet sending cycle of the terminal application layer and / or discard the access layer service packets of the terminal so that the service cycle of the V2X information is consistent with the resource cycle of the second semi-static resource;

[0195] Adjust the transmission parameters of the terminal's service packets so that the V2X information service packets can be carried by the second semi-static resource;

[0196] The number of times the service packets of the terminal are transmitted is adjusted so that the number of times the service packets of the V2X information are transmitted matches the number of times the second semi-static resource is used.

[0197] It should be noted that Uu-only terminals can adjust the V2X service cycle based on the resource cycle of the semi-static resources allocated by the first base station, so as to ensure that the service cycle of the transmitted V2X information is consistent with the cycle of the allocated semi-static resources (i.e., the second semi-static resources). Specifically, the terminal can adjust the packet transmission cycle of the internal application layer, or it can achieve this through packet loss at the access layer.

[0198] In addition, it should be noted that different types of terminals can receive unicast security information such as vehicle warnings and reminders sent by the first base station in the following ways:

[0199] Uu-only terminals listen for and receive Uu downlink unicast information;

[0200] The Uu+PC5 terminal listens for and receives Uu downlink unicast information;

[0201] PC5-only terminals listen for and receive PC5 unicast-related information.

[0202] In this embodiment of the invention, the terminal can send V2X information through the corresponding interface communication method. The communication method of this embodiment of the invention is applicable to terminals that support different interface communication methods, and can realize V2X communication in scenarios where Uu-only terminals coexist with other types of terminals.
