If the auxiliary information is specifically a partial parameter configuration in the parameter configuration for performing LTE network communication of the LTE-V2X terminal or a parameter configuration for direct communication of the LTE-V2X terminal, the next generation wireless connection - The car network NR-V2X terminal receives auxiliary information transmitted by the Long Term Evolution - Intranet LTE-V2X terminal, comprising: the NR-V2X terminal receiving the slave system message and/or dedicated signaling by the LTE-V2X terminal for performing Part of the parameter configuration obtained and transmitted in the parameter configuration of the LTE network communication; or the NR-V2X terminal receives the direct communication by the LTE-V2X terminal from the system message and/or the dedicated signaling for direct communication Parameter configuration.

In the specific implementation process, in the first and second cases, the auxiliary information is specifically the foregoing auxiliary information, and may be acquired and generated by the LTE-V2X terminal autonomously. For example, the LTE-V2X terminal obtains part of the parameter configuration from the parameter configuration for the LTE network communication of the system message and/or the dedicated signaling broadcast by the LTE base station, and then sends the parameter configuration to the NR-V2X terminal, where the acquired parameter The configuration may include a cell frequency point, a system bandwidth of the cell in which the LTE-V2X terminal camps, or the acquired parameter configuration may include a TDD subframe configuration mode used by the LTE-V2X terminal. For example, the LTE-V2X terminal acquires parameter configuration for direct communication of the LTE-V2X terminal from the dedicated signaling sent by the LTE base station, and stores the obtained parameter configuration for direct communication, when needed. Send to the NR-V2X terminal.

For the above two implementations, a person of ordinary skill in the art may make a selection according to actual needs, which is not specifically limited in the embodiment of the present invention.

After the source of the auxiliary information is explained, after obtaining the auxiliary information from the NR-V2X terminal, how to use the angle to describe the specific implementation process of step 102 is performed. Specifically, the following steps are included:

The NR-V2X terminal determines, according to the auxiliary information, whether the NR-V2X terminal interferes with the LTE network communication by using the second resource pool to perform the direct communication with the LTE-V2X terminal, and if so, the NR- The V2X terminal adjusts the transmission resource pool used for direct communication with the LTE-V2X terminal from the second resource pool to the first resource pool according to the auxiliary information. The second resource pool is a transmission resource pool used by the NR-V2X terminal to perform the direct communication with the LTE-V2X terminal within the communication range of the NR-V2X terminal before receiving the auxiliary information.

In the specific implementation process, when the NR-V2X terminal does not receive the auxiliary information sent by the LTE-V2X terminal, a transmission resource pool is selected from the resource pool list, for example, the second resource pool, and the second resource is utilized. The pool communicates directly with the LTE-V2X terminal. In the embodiment of the present application, the resource pool list includes a resource pool list of all the sending resource pools that the NR-V2X terminal can use, for example, including the sending resource pools A, B, C, D or other sending resource pools. The embodiment of the invention is not specifically limited. The resource pool list is pre-configured for the NR-V2X terminal.

In the embodiment of the present invention, after receiving the auxiliary information sent by the LTE-V2X terminal, the NR-V2X terminal first determines whether the LTE network is caused by the direct communication between the second resource pool and the LTE-V2X terminal. interference. For example, if the frequency band used when the NR-V2X terminal performs direct communication with the LTE-V2X terminal overlaps with the frequency band used when the LTE-V2X terminal performs LTE network communication, it interferes with the LTE network.

In the specific implementation process, if the NR-V2X terminal uses the second resource pool to directly communicate with the LTE-V2X terminal, it may cause interference to the LTE network. The NR-V2X terminal uses the transmission resource pool used for direct communication with the LTE-V2X terminal according to the auxiliary information. The second resource pool is adjusted to the first resource pool.

In the embodiment of the present invention, for the specific implementation process of the foregoing steps, including but not limited to the following three cases, the following three cases are respectively described below.

The first

Receiving, by the NR-V2X terminal, the first auxiliary information sent by the first LTE-V2X terminal, where the first LTE-V2X terminal is in the LTE-V2X terminal in the communication range of the NR-V2X terminal anyone.

In the specific implementation process, the NR-V2X terminal only receives the auxiliary information sent by one LTE-V2X terminal at the first moment, and the auxiliary information includes any one of the three situations of the auxiliary information. In this case, after the NR-V2X terminal receives the auxiliary information sent by the LTE-V2X terminal, the transmission resource pool is determined according to the auxiliary information, and then in the actual implementation process, after receiving the auxiliary information, the short time is received. In addition, other auxiliary information sent by other LTE-V2X terminals is received, so that the parameter information corresponding to the newly determined transmission resource pool conflicts with other auxiliary information, and still interferes with the LTE network communication, thereby requiring NR-V2X. The terminal re-determines the sending resource pool, which inevitably causes system resources to be wasted.

Therefore, in order to prevent the NR-V2X terminal from determining the transmission resource pool immediately after receiving the first auxiliary information sent by the first LTE-V2X terminal, the NR-V2X terminal frequently determines the transmission resource pool, in the embodiment of the present invention. In the middle, a technical solution including the following steps is given:

Determining, by the NR-V2X terminal, whether other auxiliary information sent by other LTE-V2X terminals except the first LTE-V2X terminal is received within a preset time period after the first time; if not, the NR- The V2X terminal adjusts, according to the first auxiliary information, a transmission resource pool used for direct communication with the LTE-V2X terminal from the second resource pool to the first resource. Pool.

In the embodiment of the present invention, the preset time period may specifically be a period in which the NR-V2X terminal needs to send information through the PC-5 interface from receiving the auxiliary information to the NR-V2X terminal, or a time period set according to actual needs. For example, 5 minutes, 8 minutes, 10 minutes, etc., or other preset time periods, those of ordinary skill in the art may set according to actual needs, which are not specifically limited in the embodiment of the present invention.

In a specific implementation process, the preset time period is taken as an example. After the NR-V2X terminal receives the first auxiliary information sent by the first LTE-V2X terminal, the second resource is not immediately adjusted according to the first auxiliary information. Instead of pooling, it is determined whether other auxiliary information transmitted by other LTE-V2X terminals is received within 5 minutes after the first time.

In the embodiment of the present invention, if other auxiliary information sent by other LTE-V2X terminals is not received within the preset time period after the first time, the second resource pool is adjusted according to the first auxiliary information, specifically, Selecting a part of the parameter of the LTE-V2X terminal in the resource pool list to configure a different resource pool as the first resource pool; or configuring the parameter for direct communication from the LTE-V2X terminal or for the NR-V2X terminal The LTE-V2X terminal selects any one of the parameter configurations in the parameter configuration of the direct communication, and configures the resource pool corresponding to any one of the parameter parameters as the first resource pool.

In the embodiment of the present invention, if other auxiliary information sent by other LTE-V2X terminals is received within a preset time period, for example, the second auxiliary information sent by the second LTE-V2X terminal, in this case, The sending resource pool is adjusted from the second resource pool to the first resource pool according to the first auxiliary information and the second auxiliary information.

In the specific implementation process, the first auxiliary information and the second auxiliary information are first The cell frequency of the cell in which the LTE-V2X terminal and the second LTE-V2X terminal reside are, for example, 1920 MHz and 2025 MHz. The resource pool list includes the sending resource pools A, B, and C as an example, and the sending resource pool A corresponds to The frequency point is 1920MHz, the frequency point corresponding to the transmission resource pool B is 2025MHz, and the frequency point corresponding to the transmission resource pool C is 1910MHz. For example, the resource pool whose frequency point is not 1920MHz or 2025MHz is selected from the resource pool list, and will be sent. Resource pool C serves as the first resource pool.

The technical solution provided by the embodiment of the present invention can prevent the NR-V2X terminal from frequently switching the transmission resource pool, thereby achieving the technical effect of improving system resource utilization efficiency.

Second

The NR-V2X terminal receives multiple sets of configuration parameters corresponding to the multiple LTE-V2X terminals sent by multiple LTE-V2X terminals at the same time; each set of configuration parameters of the multiple sets of configuration parameters is each LTE-V2X The terminal corresponds to a partial parameter configuration in a parameter configuration for performing the LTE network communication.

The NR-V2X terminal determines whether there is a resource pool in the resource pool list that is different from at least one parameter in each set of parameter configurations; if present, the NR-V2X terminal configures at least one of the foregoing and each set of parameter configurations Different resource pools serve as the first resource pool.

In a specific implementation process, the NR-V2X terminal receives multiple sets of parameter configurations corresponding to the multiple LTE-V2X terminals sent by multiple LTE-V2X terminals through multiple receiving resource pools at the same time, and the multiple sets of parameter configurations are configured. Each set of parameters is configured for each LTE-V2X terminal to be part of a parameter configuration in a parameter configuration for performing the LTE network communication, such as: in a first set of parameter configurations sent by the first LTE-V2X terminal Partial parameter configuration, part of the parameter configuration of the second set of parameter configurations sent by the second LTE-V2X terminal, the two sets of partial parameters are configured by the cell frequency of the first LTE-V2X terminal and the second LTE-V2X terminal camping cell Example, specific: 1920MHz, 2025MHz.

For example, in the resource pool list, the transmission resource pools A, B, and C are included. The frequency corresponding to the transmission resource pool A is 1920 MHz, the frequency corresponding to the transmission resource pool B is 2025 MHz, and the frequency corresponding to the transmission resource pool C is 1910 MHz. For example, a resource pool whose frequency point is not 1920 MHz or 2025 MHz is selected from the resource pool list, and the resource pool C is sent as the first resource pool.

Certainly, in the embodiment of the present invention, when the LTE-V2X terminal is a TDD-LTE terminal, the first resource pool may be determined from the resource pool list according to the TDD subframe configuration manner, and those skilled in the art may according to actual needs. The selection is not specifically limited in the embodiment of the present invention.

Further, in the embodiment of the present invention, if there is no resource pool in the resource pool list that is different from the at least one parameter in each set of parameter configurations, the method further includes: the NR-V2X terminal is the second sending resource. The pool serves as the first resource pool.

In a specific implementation process, part of the parameter configuration in the first set of parameter configurations sent by the first LTE-V2X terminal, and some parameters in the second set of parameter configurations sent by the second LTE-V2X terminal are configured in the first LTE- The cell frequency points of the V2X terminal and the second LTE-V2X terminal camping cell are taken as an example, specifically: 1920 MHz, 2025 MHz.

The resource pool list includes the sending resource pools A and B as an example. The frequency point corresponding to the sending resource pool A is 1920 MHz, and the frequency corresponding to the sending resource pool B is 2025 MHz. In this case, the frequency point information corresponding to the sending resource pool in the resource pool list is the same as the frequency point corresponding to the multiple sets of partial parameter configurations, and the NR-V2X terminal selects which sending resource pool as the first resource pool, and will be used for LTE. The network communication causes interference. In this case, the second resource pool originally selected is used as the first resource pool, thereby avoiding waste of system resources.

For example, resource pool A corresponds to parameter configuration, and resource pool A is used as the first resource. Source pool. Or in the specific implementation process, the NR-V2X terminal is used for parameter configuration for direct communication with the LTE-V2X terminal, such as: resource pool A (frequency point, system bandwidth, TDD subframe configuration mode...), resource pool B (frequency, system bandwidth, TDD subframe configuration...), resource pool C (frequency, system bandwidth, TDD subframe configuration, etc.), or other information of the resource pool included in the present invention The embodiment is not specifically limited.
