Fig. 1 is a schematic view of a vehicle networking communication system provided in an embodiment of the present application, and as shown in fig. 1, the vehicle networking communication system includes a terminal device, a network device, and a server.

A network device is a device in a wireless network, for example, a Radio Access Network (RAN) node that accesses a terminal to the wireless network. Currently, some examples of RAN nodes are: a gbb, a Transmission Reception Point (TRP), an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved Node B, or home Node B, HNB), a Base Band Unit (BBU), or a wireless fidelity (Wifi) Access Point (AP), etc. In one network structure, a network device may include a Centralized Unit (CU) node, or a Distributed Unit (DU) node, or a RAN device including a CU node and a DU node, which is not limited herein.

Wherein, the terminal equipment: the wireless terminal device may be a wireless terminal device or a wired terminal device, and the wireless terminal device may be a device with a wireless transceiving function, and may be handheld or vehicle-mounted.

The server may be an application server.

The V2X car networking communication system shown in fig. 1 comprises two communication interfaces, a PC5 interface and a Uu interface. The PC5 interface is a direct communication interface between terminal devices, and a direct communication link between terminal devices is also defined as a Sidelink or Sidechain (SL). The Uu interface communication is that the sending terminal device sends the V2X data to the network device through the Uu interface, and sends the data to the server in the V2X through the network device. And after the server processes the V2X data, the data is sent to the network equipment by the server, and is sent to the terminal equipment of the receiver through the network equipment. In the Uu interface communication mode, the network device that forwards the uplink data from the terminal device to the server and the network device that forwards the downlink data sent by the server to the terminal device of the receiving party may be the same network device or different network devices, and may be specifically determined by the server.

The communication system of the internet of vehicles shown in fig. 1 is a communication system supporting a first standard and a second standard.

Illustratively, the difference between the first system and the second system at least includes: waveform parameters, a modulation mode, bandwidth configuration, a wireless frame configuration mode, a resource multiplexing mode and a coding mode.

The communication method proposed by the present application is described in detail below with reference to specific embodiments.

Fig. 2 is a flowchart of a communication method according to an embodiment of the present application, and as shown in fig. 2, the communication method according to the embodiment of the present application includes:

s101, the terminal equipment sends first information to the network equipment.

The first information comprises carrier information and target address information of a first system, and the carrier information and the target address information of the first system have a corresponding relation.

S102, the terminal equipment sends second information to the network equipment.

The second information comprises carrier information and target address information of a second system, and the carrier information and the target address information of the second system have a corresponding relation.

When a terminal device requests a network device to schedule a transmission resource corresponding to an interested service, the terminal device reports its own carrier information and target address information to the network device.

Optionally, when the carrier information and the target address information are updated, the terminal device reports the carrier information and the target address information of the terminal device to the network device again.

Optionally, for all communication types of services, the destination address information is layer 2 destination address information obtained by converting service identification information or service identification by the V2X layer, and for example, the destination address information may be destination ID or destination L2 ID. The communication type includes broadcast, multicast, unicast, etc., and the layer 2 includes PDCP, RLC, MAC, etc.

Optionally, if the service is a broadcast service, the destination address information is service identifier information or layer 2 destination address information obtained by converting the service identifier. If the service is a multicast service, the destination address information is identification information of the group. If the service is a unicast service, the destination address information is identification information of the opposite terminal equipment.

Optionally, the first information and the second information further include communication type information corresponding to the destination address information.

Optionally, the carrier information in this application may be an index of a carrier, or any other information that can uniquely identify a carrier, such as frequency band information of a carrier.

As can be seen from fig. 1, the communication system in the internet of vehicles according to the embodiment of the present application supports a first system and a second system, where carrier information of the first system has a corresponding relationship with target address information, carrier information of the second system has a corresponding relationship with the target address information, and the corresponding relationship between carrier information of the first system and the target address information is different from the corresponding relationship between carrier information of the second system and the target address information.

Exemplarily, assuming that the first system is LTE, table 1 is a corresponding relationship between carrier information and destination address information of the first system, that is, a mapping relationship between a carrier of the first system and a destination address information list (v2 x-destinationinflistor) of the car networking.

As shown in table 1a, the carrier information of the first system includes carrier 1, carrier 2, and carrier 3, and the destination address information includes: destination ID 1, destination ID 2, destination ID3, destination ID 4, destination ID 5, and destination ID 6. The carrier 1 has a correspondence relationship with destination ID 1, destination ID 2, and destination ID3, the carrier 2 has a correspondence relationship with destination ID3, destination ID 4, and destination ID 5, and the carrier 3 has a correspondence relationship with destination ID3, destination ID 5, and destination ID 6.

TABLE 1a correspondence between carrier information and destination address information for a first system

It should be noted that table 1a is only an example of the correspondence between the carrier information of the first system and the destination address information, and optionally, as shown in table 1b, the correspondence between the carrier information of the first system and the destination address information further includes a destination ID corresponding to a carrier list, where one carrier list includes one or more carriers, for example, the destination ID3 of the first system has a correspondence with carrier 1, carrier 2, and carrier 3, and the destination ID 1 of the first system has a correspondence with carrier 1.

Exemplarily, assuming that the second system is NR, table 2a is a corresponding relationship between carrier information and destination address information of the second system, that is, a mapping relationship between carrier and v2 x-destinationinfisti of the second system.

As shown in table 2a, the carrier information of the second system includes carrier 3 and carrier 4, and the destination address information includes: destination ID3, destination ID 7, destination ID8, and destination ID 10. The carrier 3 has a correspondence relationship with destination ID3, destination ID 7, and destination ID8, and the carrier 4 has a correspondence relationship with destination ID8 and destination ID 10.

TABLE 2a correspondence between carrier information and destination address information for the second format

It should be noted that table 2a is only an example of the correspondence between the carrier information of the second system and the destination address information, and optionally, as shown in table 2b, the correspondence between the carrier information of the second system and the destination address information further includes a destination ID corresponding to a carrier list, where one carrier list includes one or more carriers, for example, the destination ID8 of the second system has a correspondence with carrier 3 and carrier 4, and the destination ID 1 of the second system has a correspondence with carrier 1.

Table 2b, correspondence between carrier information of second system and destination address information

As can be seen from tables 1a, 1b, 2a, and 2b, carriers corresponding to the first standard and the second standard may be the same, for example, carrier 3 supports both the first standard and the second standard; the target addresses corresponding to the first system and the second system may also be the same, for example, destination ID3 supports both the first system and the second system.

As can be seen from tables 1a, 1b, 2a, and 2b, the correspondence between the carrier information and the destination address information includes two ways, where way 1 is: one carrier information corresponds to one destination address information list, and one destination address information list includes one or more destination address information, for example, the destination address information list corresponding to the carrier 1 supporting the first system in table 1a is destination ID 1, destination ID 2, and destination ID 3. The mode 2 is as follows: one destination address information corresponds to one carrier information list, one carrier information list includes one or more pieces of carrier information, for example, the carrier information list corresponding to the destination ID3 in table 1b is carrier 1, carrier 2, and carrier 3 supporting the first system, that is, the destination ID3 may be scheduled on any one of carrier 1, carrier 2, and carrier 3 supporting the first system. Optionally, in the mode 2, the carrier information included in the carrier information list corresponding to the destination address information further includes system information corresponding to a carrier, for example, as shown in tables 1b and 2b, the carrier information list corresponding to the destination ID3 includes a carrier 1, a carrier 2, and a carrier 3 supporting the first system, and a carrier 3 supporting the second system.

Therefore, the corresponding relation between the carrier information and the target address information of the first system and the corresponding relation between the carrier information and the target address information of the second system are different, so that the terminal equipment sends the carrier information and the target address information of the first system and the carrier information and the target address information of the second system to the network equipment, the network equipment can be ensured to accurately distinguish the carrier information and the target address information of the first system and the carrier information and the target address information of the second system, and the accurate scheduling of subsequent services is ensured.

In a possible implementation manner, the terminal device includes the carrier information and the target address information of the first system in the first information element IE and sends the carrier information and the target address information of the second system in the second information element IE to the network device. For example, the following program code may represent an IE including carrier information (CarrierFreqCommTx) and destination address information (v2 x-destinationinflist) of the corresponding system:

when the network equipment receives the first IE, the carrier information and the target address information of the first system are obtained from the first IE, and when the network equipment receives the second IE, the carrier information and the target address information of the second system are obtained from the second IE.

The first IE or the second IE may be included in Sideline User Information (SUI) reported by the terminal device to the network device, for example, the first IE is included in a vehicle networking sideline common receive resource request of LTE format (SL-V2X-commtxresource req-LTE) and sent to the network device. The second IE is included in the NR format SL-V2X-CommTxResourceReq-NR sent to the network device.

Optionally, the first IE and the second IE indicate format information corresponding to the carrier, and one possible way is to indicate format information supported by the carrier in the IE through implicit information indication, such as names of different IEs (for example, SL-V2X-commtxresource req-LTE and SL-V2X-commtxresource req-NR); another possible way is by displaying information indication, for example, the specifically supported system information of each carrier in the IE may be indicated by one bit. Therefore, when the network equipment schedules the carrier, the target address information on the carrier corresponding to the first system or the target address information on the carrier corresponding to the second system can be determined according to the system information corresponding to the carrier information.

In a possible implementation manner, the terminal device includes the carrier information and the target address information of the first system and the carrier information and the target address information of the second system in the same information element IE and sends the information element IE to the network device.

Optionally, the first information or the second information may be in the form of a container (container), for example, as shown in the following program code, and the second information may be in the form of SL-V2X-commtxresource req-container-r 16:

optionally, in this embodiment, the system information corresponding to the carrier may be indicated, for example, the system information supported by each carrier is indicated by one bit, so that when the network device schedules the carrier, it may determine to schedule the target address information on the carrier corresponding to the first system or schedule the target address information on the carrier corresponding to the second system according to the system information corresponding to the carrier information.

It should be noted that there is no sequence between S101 and S102, that is, S101 may be executed before S102, or may be executed after S102, or S101 and S102 are executed simultaneously.

According to the method and the device, the terminal equipment carries the carrier information and the target address information corresponding to the first system and the second system in the same IE and sends the carrier information and the target address information to the network equipment, so that air interface overhead can be saved, or the carrier information and the target address information corresponding to the first system and the second system are carried in different IEs and sent to the network equipment, so that the flexibility of sending the carrier information and the target address information corresponding to the first system and the second system can be improved.

Furthermore, the terminal device sends the carrier information and the target address information corresponding to the first system and the second system to the network device, so that the carrier of the first system can be accurately scheduled based on the carrier information and the target address information of the first system when the network device is scheduled at the later stage, and the carrier of the second system can be accurately scheduled based on the carrier information and the target address information of the second system, thereby solving the problem that the network device cannot perform scheduling on the correct carrier, and further improving the communication reliability of the vehicle networking communication system supporting the first system and the second system.

As can be seen from tables 1a and 2a, carrier 3 supports both the first system (e.g., LTE) and the second system (e.g., NR), but the target address information of carrier 3 about the first system and the second system is not exactly the same. Therefore, when the network device schedules carrier 3, it needs to specify whether to schedule the target address information on carrier 3 corresponding to LTE or schedule the target address information on carrier 3 corresponding to NR.

S103, the terminal equipment sends the BSR of the first link to the network equipment.

The BSR includes a target address information index, which is an index of the target address information in the first information or an index of the target address information in the second information.

As shown in fig. 1, the first link is a wireless direct communication link between the terminal device and another terminal device. Alternatively, the wireless direct communication interface between the terminal devices may be defined as a PC5 port.

Note that S103 is executed after S101 and S102.

In an actual service transmission stage, the terminal device sends a Buffer Status Report (Sidelink BSR) of the first link to the network device, and the network device learns, through the BSR, a Buffer amount of a service to be sent by the terminal device at the port PC 5.

The BSR includes a Destination address information index (Destination index), which may be an index of the Destination address information in the first information or an index of the Destination address information in the second information.

As shown in table 1 and table 2, a carrier may correspond to a target address information list, a target address information list may include one or more target address information, and a target address information in a target address information list may have a target address information index corresponding thereto.

In the existing car networking communication system supporting one system, the target address information indexes are numbered according to the sequencing sequence of the target address information, however, when the car networking communication system supports two systems, in order to enable the network device to accurately identify whether the target address information index carried in the BSR reported by the terminal device is of the first system or the second system, the indexes of the target address information of different systems need to be renumbered.

On the basis of the embodiment shown in fig. 2, the following describes in detail how to number the target address information indexes of the target address information included in the first information and the second information in combination with different implementations, and it should be noted that the numbering ways of the target address information indexes related to the embodiments of the present application include, but are not limited to, the following ways.

(1) In the first case, the first Information and the second Information are included in the same Information Element (IE), for example, both the first Information and the second Information are included in SL-V2X-comtxresource req and sent to the network device.

Optionally, the first information or the second information may be in the form of a container (container), for example, when the Uu port is an LTE Uu port, the second information is in the form of container and the first information is included in the same IE; when the Uu port is an NR Uu port, the first information takes the form of a container and the second information is included in the same IE.

In this case, in order to distinguish the first information from the second information in one information unit, the first information and/or the second information may further include system information corresponding to the carrier. For example, the first information includes system information of a first system, and the second information does not include system information of a second system, so that the network device may obtain the first information corresponding to the first system from the information unit, and determine the remaining information as the second information corresponding to the second system. Or the second information includes system information of the second system, and the first information does not include system information of the first system, so that the network device can obtain the second information corresponding to the second system from the information unit, and the remaining information is determined as the first information corresponding to the first system. Or, the first information includes system information of a first system, and the second information includes system information of a second system, so that the network device can obtain, from the information unit, first information corresponding to the first system and second information corresponding to the second system.

A. In the first case, if the number of the destination address information index is numbered directly, the number of the destination address information index includes, but is not limited to, the following three types:

in a first mode, the number of the destination address information index of the destination address information included in the first information and the number of the destination address information index of the destination address information included in the second information are adjacent in sequence.

Illustratively, on the basis of table 1a, the correspondence relationship between the carrier information of the first system, the destination address information, and the destination address information index is shown in table 3, where the numbers of the destination address information indexes of the first system are sequentially numbered according to the arrangement order of the destination address information in the first information, and the sequential numbers may be ascending numbers or descending numbers as in table 3.

Table 3, correspondence between carrier information of first system, destination address information, and destination address information index

Exemplarily, on the basis of the above table 2a, the correspondence relationship between the carrier information of the second system, the destination address information and the destination address information index is shown in table 4, where the numbers of the destination address information indexes of the second system are sequentially arranged according to the arrangement order of the destination address information in the second information. The sequence number may be an ascending sequence number or a descending sequence number as shown in table 4.

Table 4, correspondence between carrier information, destination address information, and destination address information index of the second system

As is apparent from tables 3 and 4 described above, the numbers of the destination address information indexes of the destination address information included in the first information and the numbers of the destination address information indexes of the destination address information included in the second information are adjacent in order, for example, the numbers of the destination address information indexes of the destination address information included in the first information are 1 to 9, and the numbers of the destination address information indexes of the destination address information included in the second information are 10 to 14.

Table 3 and table 4 are merely an example, and optionally, the target address information indexes of the target address information included in the second information may be numbered first, and then the target address information indexes of the target address information included in the first information may be numbered, for example, the target address information indexes of the target address information included in the second information are numbered 1 to 5, and the target address information indexes of the target address information included in the first information are numbered 6 to 14.

Optionally, numbers of destination address information indexes of destination address information included in the first information may be sorted in a descending order, for example, starting from a preset value 100, numbers of destination address information indexes of destination address information included in the first information are sorted in a descending order from 100 to 92, and numbers of destination address information indexes of destination address information included in the second information are sorted in a descending order from 91 to 87. Or, the numbers of the target address information indexes of the target address information included in the second information are sequentially arranged in a descending order from 100 to 96, and the numbers of the target address information indexes of the target address information included in the first information are sequentially arranged in a descending order from 95 to 87.

In a second mode, the number of the destination address information index of the destination address information included in the first information and the number of the destination address information index of the destination address information included in the second information are respectively numbered sequentially, and a difference between a minimum number of the destination address information index of the destination address information included in the first information and a minimum number of the destination address information index of the destination address information included in the second information is equal to M, where M is a positive integer.

As shown in table 3, the numbers of the destination address information indexes of the destination address information included in the first information are sequentially numbered according to the arrangement order of the destination address information included in the first information, and the sequential numbers may be the ascending numbers or the descending numbers as shown in table 3.

In this application, a difference between a minimum number of a target address information index of target address information included in the first information and a minimum number of a target address information index of target address information included in the second information is equal to a positive integer M.

It should be noted that the value of M should ensure that the number of the destination address information index of the first information and the number of the destination address information index of the second information do not overlap. For example, if the number range of the target address information index of the first information is 1 to 10, M should be a positive integer greater than or equal to 10, for example, 10 at the minimum.

For example, assuming that M is 99, on the basis of table 2, the correspondence relationship between the carrier information of the second system, the destination address information, and the destination address information index included in the second information may be as shown in table 5, where numbers of the destination address information indexes of the second system are sequentially arranged according to an arrangement order of the destination address information in the second information. The sequence number may be an ascending sequence number or a descending sequence number as shown in table 5.

Table 5, correspondence between carrier information, destination address information, and destination address information index of the second system

As can be seen from tables 3 and 5 described above, the difference between the minimum number 1 of the target address information index of the target address information included in the first information and the minimum number 100 of the target address information index of the target address information included in the second information is equal to the positive integer M99.

Alternatively, the terminal device may configure the M in different ways, for example, the terminal device is configured by at least one of radio resource control RRC dedicated signaling from the network device, a system broadcast message from the network device, and preset configuration information.

Optionally, the RRC dedicated signaling, the system broadcast message, and the preset configuration information have configuration priorities, for example, the configuration priorities of the RRC dedicated signaling, the system broadcast message, and the preset configuration information are sequentially reduced. Thus, when the terminal device simultaneously obtains the RRC dedicated signaling, the system broadcast message, and the preset configuration information, the value of M may be determined according to the configuration priority among the three, for example, the value of M is determined according to the RRC dedicated signaling. Or, when the terminal device does not obtain the RRC dedicated signaling, the system broadcast message, and the preset configuration information at the same time, the configuration information with the higher priority is used to cover the configuration information with the lower priority, for example, the terminal device receives the system broadcast message from the network device in the 1 st second, and receives the RRC dedicated signaling from the network device in the 1.5 th second, then the terminal device covers the system broadcast message using the RRC dedicated signaling, that is, the terminal device determines the value of M according to the RRC dedicated signaling.

In a third aspect, the number of the destination address information index of the destination address information included in the first information and the number of the destination address information index of the destination address information included in the second information are respectively numbered sequentially, and the minimum number of the destination address information index of the destination address information included in the first information is equal to the minimum number of the destination address information index of the destination address information included in the second information.

As shown in table 3, the numbers of the destination address information indexes of the destination address information included in the first information are sequentially numbered in the order of arrangement of the destination address information included in the first information.

Meanwhile, the numbers of the target address information indexes of the target address information included in the second information are sequentially numbered according to the arrangement order of the target address information included in the second information. And the minimum number of the target address information index of the target address information included in the first information is equal to the minimum number of the target address information index of the target address information included in the second information.

Exemplarily, on the basis of the above table 2a, a correspondence relationship between the carrier information of the second system, the destination address information, and the destination address information index is shown in table 6, where the destination address information indexes of the destination address information included in the second information are sequentially numbered according to the arrangement order of the destination address information included in the second information. And the minimum number 1 of the target address information index of the target address information included in the second information is equal to the minimum number 1 of the target address information index of the target address information included in the first information.

Table 6, correspondence between carrier information, destination address information, and destination address information index of the second system

As can be seen from tables 3 and 6, the number of the destination address information index of the destination address information included in the first information and the number of the destination address information index of the destination address information included in the second information are sequentially numbered from a predetermined value (e.g., 1).

In this embodiment, the number of the destination address information index of the destination address information included in the first information overlaps with the number of the destination address information index of the destination address information included in the second information, for example, destination index 3 may be the destination address information index of destination ID3 in table 3, and the carrier corresponding to destination ID3 is carrier 1, carrier 2, and carrier 3 of the first system; the destination address information index of destination ID8 in table 6 may also be used, and the carriers corresponding to destination ID8 are carrier 3 and carrier 4 of the second system. Thus, when the terminal device reports the destination index 3 in the BSR, the network device cannot determine whether the destination index 3 corresponds to the destination ID3 in the first format or the destination ID8 in the second format, and cannot determine the carrier corresponding to the format corresponding to the destination index 3.

In order to solve the above technical problem, in the embodiment of the present application, the BSR further includes system information corresponding to carriers, for example, the BSR includes a destination index 3 and first system information, so that after receiving the BSR, the network device searches for a destination ID3 corresponding to the destination index 3 from a corresponding relationship between the carrier information and destination address information shown in table 3, where the destination ID3 corresponds to a carrier 1, a carrier 2, and a carrier 3 of the first system, and then the network device may determine that the carrier corresponding to the destination index 3 in the BSR is the carrier 1, the carrier 2, and the carrier 3 of the first system, and a subsequent network device may schedule corresponding resources for the terminal device on any one of the three carriers.

Optionally, in order to save uplink resources, the system information corresponding to the target address information index included in the BSR may be represented by one bit (bit).

B. In the first case, when the number of the destination address information index is determined according to the number range of the destination address information index, the number of the destination address information index includes, but is not limited to, the following three types:

in a first mode, a number range of a destination address information index of the destination address information included in the first information and a number range of a destination address information index of the destination address information included in the second information are sequentially adjacent to each other.

For example, it is assumed that the first information includes target address information having a target address information index number ranging from 1 to 50, and the second information includes target address information having a target address information index number ranging from 51 to 100. The target address information indexes of the target address information included in the first information are numbered within the number range 1 to 50, such as sequential numbers, or are numbered according to a preset number rule. The second information includes target address information indexes of target address information numbered within a number range 51 to 100, such as sequential numbers, or numbers according to a preset numbering rule.

The size of the number range of the destination address information index of the destination address information included in the first information and the size of the number range of the destination address information index of the destination address information included in the second information may be adjusted according to actual needs.

In a second mode, the number of the destination address information index of the destination address information included in the first information and the number of the destination address information index of the destination address information included in the second information are sequentially numbered within respective number ranges, and a difference between a maximum number of the number range of the destination address information index of the destination address information included in the first information and a minimum number of the number range of the destination address information index of the destination address information included in the second information is equal to P, where P is a positive integer.

In this implementation, the difference P between the maximum number of the number range of the target address information index of the target address information included in the first information and the minimum number of the number range of the target address information index of the target address information included in the second information is a positive integer greater than or equal to 1.

Optionally, the size of the number range of the target address information index of the target address information included in the first information may be the same as or different from the size of the number range of the target address information index of the target address information included in the second information, and is specifically determined according to actual needs.

For example, assuming that P is 50, and the number range of the target address information index of the target address information included in the first information is 1 to 50, the number range of the target address information index of the target address information included in the second information is 100 to 140. Thus, the target address information indexes of the target address information included in the first information are sequentially numbered in the number range of 1 to 50, and the target address information indexes of the target address information included in the second information are sequentially numbered in the number range of 100 to 140.

Optionally, the P may be configured by the terminal device through at least one of a radio resource control RRC dedicated signaling from the network device, a system broadcast message from the network device, and preset configuration information. Optionally, the priority of the configuration P of the RRC dedicated signaling, the system broadcast message, and the preset configuration information is sequentially reduced.

In a third aspect, the number of the destination address information index of the destination address information included in the first information and the number of the destination address information index of the destination address information included in the second information are sequentially numbered within respective number ranges, and a minimum number of the number range of the destination address information index of the destination address information included in the first information is equal to a minimum number of the number range of the destination address information index of the destination address information included in the second information. The first information or the second information may further include system information corresponding to the carrier index.

For example, assuming that the number range of the numbers of the destination address information indexes of the destination address information included in the first information is 1 to 50, the number range of the numbers of the destination address information indexes of the destination address information included in the second information is 1 to 100, and the minimum numbers of the number ranges of the numbers of the destination address information indexes of the first information and the second information including the destination address information are equal, for example, both are 1. And the target address information indexes of the target address information included in the first information are sequentially numbered within the number range of 1 to 50, and the target address information indexes of the target address information included in the second information are sequentially numbered within the number range of 1 to 100.

In this way, there is a problem that the same destination address information index corresponds to carriers of two systems in number, and in order to solve the problem, system information corresponding to the carrier is also included in the first information or the second information.

Optionally, in order to save uplink resources, the system information corresponding to the target address information index included in the first information or the second information may be represented by one bit (bit).

In the application, when the first information and the second information are included in the same information unit, the number of the target address information index of the target address information included in the first information and the number of the target address information index of the target address information included in the second information are renumbered in the above manner, so that when the network device receives the target address information index in the BSR sent by the terminal device, the carrier corresponding to the system to which the target address information index corresponds can be accurately determined, and resource scheduling is subsequently performed on the carrier.

(2) In the second case, the first information and the second information are included in different information units.

For example, the first standard corresponding to the first information is LTE, the second standard corresponding to the second information is NR, so that the terminal device may include the first information in SL-V2X-comtxresource req-LTE and transmit the first information to the network device, and include the second information in SL-V2X-comtxresource req-NR and transmit the second information to the network device.

A. In the second case, if the number of the destination address information index is numbered directly, the number of the destination address information index includes, but is not limited to, the following three types:

The specific implementation process of this method can refer to the above tables 3 and 4, and is not described herein again.

In a second mode, the number of the destination address information index of the destination address information included in the first information and the number of the destination address information index of the destination address information included in the second information are respectively numbered sequentially, and a difference between a minimum number of the destination address information index of the destination address information included in the first information and a minimum number of the destination address information index of the destination address information included in the second information is equal to R, where R is a positive integer.

The specific implementation process of this method can be shown in table 3 and table 5, and is not described herein again.

Optionally, the difference R may be configured by the terminal device through at least one of radio resource control RRC dedicated signaling from the network device, a system broadcast message from the network device, and preset configuration information. Optionally, the priority of the configuration R of the RRC dedicated signaling, the system broadcast message, and the preset configuration information is sequentially reduced.

The specific implementation process of this method can be shown in table 3 and table 6, and is not described herein again.

B. In the second case, when the number of the destination address information index is determined according to the number range of the destination address information index, the number of the destination address information index includes, but is not limited to, the following two types:

For a specific implementation process of this method, reference may be made to the first method in the example B of the first case, and details are not described here.

For a specific implementation process of this method, reference may be made to the second method in the example B of the first case, and details are not described here.

In a third mode, the number of the destination address information index of the destination address information included in the first information and the number of the destination address information index of the destination address information included in the second information are sequentially numbered within respective number ranges, and the minimum number of the number range of the destination address information index of the destination address information included in the first information is equal to the minimum number of the number range of the destination address information index of the destination address information included in the second information; the first information or the second information may further include system information corresponding to the carrier index.

For a specific implementation process of this method, reference may be made to the third method in the example B of the first case, and details are not described here.

In this application, when the first information and the second information are included in different information units, the number of the target address information index of the target address information included in the first information and the number of the target address information index of the target address information included in the second information are renumbered in the above manner, so that when the network device receives the target address information index in the BSR sent by the terminal device, the carrier corresponding to the system to which the target address information index corresponds can be accurately determined, and resource scheduling on the carrier subsequently can be realized.

Thus, after receiving the BSR reported by the terminal device, the network device matches the corresponding carrier from the first information or the second information reported by the corresponding terminal device according to the Destination index in the BSR, and subsequent scheduling of the network device is performed on the corresponding carrier of the corresponding system.

For example, it is assumed that the BSR includes a Destination index 2 and a Destination index 7, where the Destination index 2 is an index of a Destination ID 2 in the first information, and as can be seen from table 1, the Destination ID 2 of the first system corresponds to a carrier 1, so that the network device can determine the carrier 1 according to the Destination index 2, and then perform scheduling on the carrier 1 corresponding to the first system. The Destination index 7 is an index of the Destination ID3 in the second information, and as can be seen from table 2, the Destination ID3 of the second system corresponds to the carrier 3, the carrier 3 simultaneously supports the first system and the second system, and the Destination ID3 corresponds to the second information of the second system, so that the network device can determine the carrier 3 of the second system according to the Destination index 7, and then perform subsequent scheduling on the carrier 3 corresponding to the second system.

The target address information index included in the BSR is an index of target address information in first information or an index of target address information in second information, where the first information corresponds to a first system and the second information corresponds to a second system. That is to say, the target address information index in this step includes system information explicitly or implicitly, so that after obtaining the target address information index, the network device can accurately find carrier information corresponding to the system corresponding to the target address information index from the received table 1a or table 2a, thereby avoiding a problem that the network device cannot perform scheduling on a correct carrier due to the fact that the network device cannot acquire the carrier corresponding to the system corresponding to the target address information index in the BSR.

In the communication method provided by the embodiment of the application, the terminal device sends first information comprising carrier information of a first system and target address information to the network device, wherein the carrier information of the first system and the target address information have a corresponding relationship, and sends second information comprising carrier information of a second system and the target address information to the network device, and the carrier information of the second system and the target address information have a corresponding relationship. Then, the terminal device sends a BSR of the first link to the network device, where the BSR includes a target address information index, and the target address information index is an index of target address information in the first information or an index of target address information in the second information. After the terminal equipment sends the carrier information and the target address information of the first system and the carrier information and the target address information of the second system to the network equipment, when the network equipment receives the target address information index in the first link BSR sent by the terminal equipment, the carrier corresponding to the system corresponding to the target address information index can be accurately obtained from the carrier information and the target address information of the first system or the carrier information and the target address information of the second system according to the target address information index, and the problem that the network equipment cannot perform scheduling on correct frequency points is solved, so that the communication reliability of the vehicle networking communication system supporting the first system and the second system is improved.

Fig. 3 is a flowchart of a communication method according to an embodiment of the present application, and as shown in fig. 3, the communication method according to the embodiment of the present application includes:

s201, the terminal device determines a BSR of a first system of a first link.

The BSR of the first system may include at least one first message, and the first message may include an index of target address information, LCG information, and information of Buffer Size (BS).

The information of the size of the cache area has a corresponding relation with the index of the target address information and the LCG information.

S202, the terminal equipment determines the BSR of the second system of the first link.

The BSR of the second system includes at least one second message, where the second message includes an index of target address information, LCG information, and information of buffer size.

The first information and the second information in the embodiment of the present application are named the same as the first information and the second information in the embodiment shown in fig. 2, but are different concepts.

The first link is a direct connection wireless communication link between the terminal device and other terminal devices.

The index of the target address information is one selected from one or more indexes associated with the target address information in the corresponding system. For example, for destination ID3, both the first system and the second system are supported, and when the buffer size BS of the corresponding service in the first system is determined to be reported, one of the associated indexes, destination index1, destination index 4 and destination index 7 in table 3 corresponding to the first system is selected as the destination index in the first information corresponding to the destination ID 3; when the BS reporting the corresponding service in the second system is determined, the associated index destination index 10 is obtained from the table 4 corresponding to the second system and is used as the destination index in the second information corresponding to the termination ID 3.

Optionally, the first standard may be LTE, and the second standard is NR, or the second standard is LTE and the first standard is NR.

In the implementation of the present application, for different systems, corresponding BSRs are different, and it is assumed that fig. 4 is a BSR of a first system, as shown in fig. 4, the BSR of the first system includes one or more first information, where the first information includes an index of target address information, LCG information, and information of a buffer size BS. An index of destination address information corresponds to one or more LCG information, one LCG information corresponds to information of a buffer size BS, and one LCG includes one or more Logical Channels (LCHs). According to the above correspondence, the index of one target address information and one LCG information uniquely determine one buffer size BS, and the BS is the sum of the data amount of the data to be transmitted on all LCHs in the LCG. For example, index1 and LCG 1 of the target address information correspond to one BS 1, and the BS 1 indicates the sum of data volumes of data to be transmitted on all LCHs in LCG 1 of index1 of the target address information; the index 2 and the LCG 2 of the target address information correspond to one BS 2, and the BS 2 indicates the sum of the data amount of the data to be transmitted on all the LCHs in the LCG 2 of the index 2 of the target address information.

Optionally, fig. 4 may also be a BSR of a second system, as shown in fig. 4, the BSR of the second system includes one or more second information, where the second information includes an index of target address information, LCG information, and information of a buffer size BS. An index of target address information corresponds to one or more LCG information, one LCG information corresponds to information of a buffer size BS, and one LCG includes one or more LCHs.

Optionally, if the uplink resource (UL grant) is not sufficient, the BSR may be a truncated BSR (truncated Sidelink BSR), that is, the first information and/or the second information are sorted according to a preset priority, and the first information and/or the second information with a higher priority are/is reported.

It should be noted that there is no sequence between S201 and S202, that is, S201 may be executed before S202, or may be executed after S202, or S201 and S202 are executed simultaneously.

S203, the terminal equipment sends the BSR of the first system and the BSR of the second system to the network equipment.

According to the above S201 and S202, the terminal device determines the BSR of the first system and the BSR of the second system of the first link, and then, the terminal device sends the BSR of the first system and the BSR of the second system of the first link to the network device, so that the network device determines, according to the first information and the second information in the BSR, the data volume to be transmitted in each LCG of each target address information in the corresponding system, and allocates a reasonable scheduling resource to the terminal device on the corresponding carrier of the corresponding system.

In a possible implementation manner, the terminal device includes the BSR of the first system in a first buffer status report Media Access Control layer Control Element (BSR MAC CE) and sends the BSR of the second system in a second BSR MAC CE to the network device. When the network equipment receives a first BSR MAC CE, a BSR of a first system is obtained from the first BSR MAC CE, and when the network equipment receives a second BSR MAC CE, a BSR of a second system is obtained from the second BSR MAC CE.

Optionally, the first BSR MAC CE and the second BSR MAC CE include corresponding system information, and one possible way is to indicate the system information of the BSR MAC CE through implicit information indication, for example, names of different BSR MAC CEs; another possible way is to indicate the system information of the first BSR MAC CE by displaying information indication, for example, indicating the system information of the first BSR MAC CE by a bit in the first BSR MAC CE, and indicating the system information of the second BSR MAC CE by a bit in the second BSR MAC CE. Thus, when the network device allocates the scheduling resource, it may determine whether to allocate the scheduling resource of the first system or allocate the scheduling resource of the second system according to the system information indicated by the first BSR MAC CE and the second BSR MAC CE.

In another possible implementation manner, the terminal device includes the BSR of the first system and the BSR of the second system in the same BSR MAC CE and sends the BSR of the first system and the BSR of the second system to the network device; optionally, the system information corresponding to the BSRs may be indicated at this time, and for example, the system information of each BSR is indicated by one bit, so that when the network device allocates the scheduling resource, it may determine whether to allocate the scheduling resource of the first system or allocate the scheduling resource of the second system according to the system information of the BSRs.

In the embodiment of the application, a terminal device determines a first-system BSR of a first link, where the first-system BSR includes at least one piece of first information, and the first information includes an index of target address information, LCG information of a logical channel group, and information of a buffer size, where the information of the buffer size has a corresponding relationship with the index of the target address information and the LCG information; determining a BSR of a second system of the first link, wherein the BSR of the second system comprises at least one piece of second information, the second information comprises an index of target address information, LCG information and information of the size of a buffer area, and the information of the size of the buffer area and the index of the target address information and the LCG information have a corresponding relation; and then, the terminal equipment sends the BSR of the first system and the BSR of the second system to the network equipment to provide a basis for subsequent resource scheduling of the network equipment.

On the basis of the foregoing embodiment, the following will describe in detail, in combination with different implementation manners, how to sort the first information and the second information in the buffer status report Media Access Control Element (BSR MAC CE) of the BSR, where it is to be noted that the sorting manners of the first information and the second information in the BSR MAC CE of the BSR according to the embodiments of the present application include, but are not limited to, the following several manners.

(1) In a first case, if the BSR of the first system and the BSR of the second system are included in different BSR MAC CEs, the method in the embodiment of the present application further includes:

s2001, the terminal device determines, according to the first preset priority rule, the ranking of the at least one first information in the BSR MAC CE of the BSR of the first system, or determines the ranking of the at least one second information in the BSR MAC CE of the BSR of the second system.

The above S2001 is performed before the above S201.

Specifically, if the BSR of the first system and the BSR of the second system are included in different BSR MAC CEs, for example, the BSR 1 of the first system is included in the BSR MAC CE 1, the BSR 2 of the second system is included in the BSR MAC CE 2, and the BSR 1 of the first system includes one or more pieces of first information, so that when the terminal device reports the BSR 1 to the network device, the first information included in the BSR 1 needs to be sorted, for example, the first information included in the BSR 1 is sorted according to a first preset priority rule. The BSR 2 of the second system includes one or more second information, so that when the terminal device reports the BSR 2 to the network device, the second information included in the BSR 2 needs to be sorted, for example, each second information included in the BSR 2 is sorted according to a first preset priority rule.

Illustratively, the first preset priority rule includes:

the terminal equipment arranges the at least one piece of first information in a descending order according to the priority of the at least one piece of first information, wherein the priority of the first information is the highest priority of a logical channel to be transmitted in LCG (logical channel group) associated with LCG information included in the first information; or, the at least one second message is sorted in descending order according to the at least one second message, wherein the priority of the second message is the highest priority of the logical channels in the LCG associated with the LCG message included in the second message.

Continuing to refer to fig. 4, assume that fig. 4 is BSR 1 of the first system, where the BSR 1 includes 4 pieces of first information, where the first information 1 includes: destination index1, LCG 1 and buffer size 1, and the first information 2 includes: destination index1, LCG 3 and buffer size 2, the first information 3 includes: destination index 2, LCG 2 and buffer size 3, and the first information 4 includes: destination index 2, LCG 3 and buffer size 4. The logical channels to be transmitted by the LCG 1 included in the first information 1 are LCH 1 and LCH 2, the logical channel to be transmitted by the LCG 3 included in the first information 2 is LCH 3, the logical channel to be transmitted by the LCG 2 included in the first information 3 is LCH 4, and the logical channels to be transmitted by the LCG 3 included in the first information 4 are LCH 5 and LCH 6. The priority of LCH 1 in LCG 1 included in the first information 1 is higher than the priority of LCH 2, and therefore, the highest priority of the logical channel to be transmitted with data in LCG 1 associated with the first information 1 is the priority of LCH 1, the priority of LCH 5 in LCG 3 included in the first information 4 is higher than the priority of LCH 6, and therefore, the highest priority of the logical channel to be transmitted with data in LCG associated with the first information 4 is the priority of LCH 5, and the highest priorities of the logical channels in LCGs associated with the LCG information included in the first information are arranged in the order from top to bottom: the priority of LCH 1 of the first information 1, the priority of LCH 4 of the first information 3, the priority of LCH 5 of the first information 4, and the priority of LCH 3 of the first information 2, and further the order obtained for the first information in the BSR MAC CE of the first format is shown in table 7:

TABLE 7 ordering of first information in BSR MAC CE of BSR of first System

First information 1	LCG 1	buffer size 1	destination index 1
				First information 3	LCG 2	buffer size 3	destination index 2
First information 4	LCG 3	buffer size 4	destination index 2
				First information 2	LCG 3	buffer size 2	destination index 1

Similarly, referring to the above-mentioned ordering manner of the first information in the BSR MAC CE of the first system, the ordering of the second information in the BSR MAC CE of the second system may be obtained, which is not described herein again.

Optionally, the Priority of the LCH within the LCG may be represented by a short-range Packet Priority (ProSe Per-Packet Priority, PPPP), a short-range Packet Reliability (ProSe Per-Packet Reliability, PPPR), a PC5 port fifth-generation communication system quality of service identifier (PC5 QoS identifier, PQI), an internet of vehicle communication system quality of service identifier (V2X QoS identifier, VQI), a fifth-generation communication system quality of service identifier (5G QoS identifier, 5QI), a PC5 QoS flow identifier (PC5 QoS flow identifier, PC5 QFI), or a specific Priority associated with the LCH itself, where the smaller the PPPP value is, the higher the Priority is, and the Priority of the PQI, VQI, 5QI or LCH 5 QFI is the Priority of the set of QoS parameters associated therewith (e.e. the Priority of 5 QoS identifier of the 5 broadcast QoS mapping).

Optionally, if the first standard is LTE and the second standard is NR, each LCH in the LCG included in the first information represents a priority according to a PPPP or PPPR value, and each LCH in the LCG included in the second information represents a priority according to a PQI, VQI, 5QI, PC5 QFI, or a priority value associated with the LCH.

After determining the ordering of the first information in the BSR MAC CE of the first system and the ordering of the second information in the BSR MAC CE of the second system according to the above steps, it is further required to determine the ordering of the BSR MAC CE of the first system and the BSR MAC CE of the second system, and the ordering may specifically include the following ordering manners:

in the first mode, the BSR MAC CE of the BSR of the first system is arranged in front of the BSR MAC CE of the BSR of the second system; or the arrangement of the BSR MAC CEs of the BSR of the first system is behind the BSR MAC CEs of the BSR of the second system.

And determining the ordering of the BSR MAC CE of the first system and the BSR MAC CE of the second system according to the priority of the first information with the highest priority in the at least one first information included in the BSR MAC CE of the first system and the priority of the second information with the highest priority in the at least one second information included in the BSR MAC CE of the second system, wherein the priority of the first information is the highest priority of a logical channel to be transmitted with data in an LCG associated with the LCG information included in the first information, and the priority of the second information is the highest priority of a logical channel to be transmitted with data in an LCG associated with the LCG information included in the second information. For example, referring to the method in table 7 above, of at least one first information included in the BSR MAC CE of the BSR of the first standard, the highest priority of the logical channel to be transmitted in the LCG associated with the LCG information included in each first information is used as the priority of each first information; in a similar way, in at least one piece of second information included in the BSR MAC CE of the BSR of the second system, the highest priority of the logical channel to be transmitted in the LCG associated with the LCG information included in each piece of second information is used as the priority of each piece of second information. The BSR MAC CE of the BSR of the first system is assumed to include first information with the highest priority in the at least one first information as first information 1, and the BSR MAC CE of the BSR of the second system is assumed to include second information with the highest priority in the at least one second information as second information 3. At this time, if the priority of the first information 1 is higher than that of the second information 3, the BSR MAC CE of the BSR of the first system is arranged before the BSR MAC CE of the BSR of the second system, and if the priority of the second information 3 is higher than that of the first information 1, the BSR MAC CE of the BSR of the second system is arranged before the BSR MAC CE of the BSR of the first system. If the parameter for representing the priority of the first information 1 and the parameter for representing the priority of the second information 3 are different, the parameter for representing the priority of the first information 1 and the parameter for representing the priority of the second information 3 may be converted into the same parameter and compared.

According to the method of the embodiment of the application, when the BSR of the first system and the BSR of the second system are included in different BSR MAC CEs, at least one first message is determined to be sequenced in the BSR MAC CE of the first system and at least one second message is determined to be sequenced in the BSR MAC CE of the second system, so that the network equipment can preferentially allocate corresponding scheduling resources to the first message with high priority and the second message with high priority according to the sequencing of the first message and the second message reported by the terminal equipment.

(2) In a second case, if the BSR of the first system and the BSR of the second system are included in the same BSR MAC CE, the method in the embodiment of the present application further includes:

s2002, determining, according to a second preset priority rule, an order of the at least one first information and the at least one second information in the BSR MAC CE.

It should be noted that there is no precedence relationship between the above S2001 and S2002, and two technical solutions are parallel.

The above S2002 is performed before the above S202.

Specifically, if the BSR 1 of the first system and the BSR 2 of the second system are included in the same BSR MAC CE, that is, the BSR MAC CE includes at least one first information in the BSR 1, and also includes at least one second information in the BSR 2, when the terminal device reports the first information and the second information to the network device, it needs to determine that each first information and each second information are ordered in the BSR MAC CE, for example, according to a second preset priority rule, each first information and each second information are ordered in the BSR MAC CE.

Illustratively, the second preset priority rule includes the following modes:

in a first mode, at least one first message is arranged before at least one second message; alternatively, the at least one first information is arranged after the at least one second information.

In the second mode, at least one first message is interspersed in at least one second message.

For example, first information of the at least one first information having a priority higher than or equal to the first priority is ranked before the at least one second information, and the at least one second information is ranked before first information of the at least one first information having a priority lower than or equal to the first priority. The first priority is a preset value and can be set according to actual needs. Assuming that the first priority is threshold 2, the first information with a priority higher than threshold 2 in each first information may be ranked first, then all the second information may be ranked, and finally, the first information with a priority lower than threshold 2 in each first information may be ranked.

For another example, the second information having a priority higher than or equal to the second priority in the at least one second information is ranked before the at least one first information, and the at least one first information is ranked before the second information having a priority lower than or equal to the second priority in the at least one second information. Assuming that the second priority is threshold 3, the second information with a priority higher than threshold 3 in each second information may be arranged first, then all the first information may be sorted, and finally the second information with a priority lower than threshold 3 in each second information may be arranged.

Optionally, the first priority and the second priority may be configured according to at least one of RRC dedicated signaling, system broadcast message and preset configuration information sent by the network device, and optionally, the priorities of the first priority and the second priority configured by the RRC dedicated signaling, the system broadcast message and the preset configuration information are sequentially reduced.

Optionally, the priority of the first information or the second information may be characterized by a specific priority associated with PPPP, PPPR, PQI, VQI, 5QI, PC5 QFI, or LCH itself. Optionally, if the first standard is LTE and the second standard is NR, the priority of the first information may be characterized by a PPPP or PPPR value, and the priority of the second information may be characterized by a priority value associated with a PQI, VQI, 5QI, PC5 QFI, or LCH.

In a third mode, the at least one first message and the at least one second message are ordered according to a uniform priority.

Specifically, if the parameter for representing the priority of the first information is different from the parameter for representing the priority of the second information, the parameter for representing the priority of each first information in the at least one first information and the parameter for representing the priority of each second information in the at least one second information are converted into the same parameter. For example, the PPPP value is used to characterize the priority of the first information, and the PQI is used to characterize the priority of the second information, so that the PPPP value characterizing the priority of the first information may be converted into a PQI value, or the PQI value characterizing the priority of the second information may be converted into a PPPP value. And sequencing each first information and each second information according to the converted uniform priority, thereby improving the sequencing accuracy.

Optionally, the unified priority has a mapping relationship with the priority of the at least one first information and the priority of the at least one second information. For example, the terminal device maintains the mapping table, and can find the uniform priority corresponding to the priority of the at least one first information and the uniform priority corresponding to the priority of the at least one second information through the mapping table, so that the terminal device can conveniently sort the first information and the second information according to the uniform priority corresponding to the priority of the first information and the uniform priority corresponding to the priority of the second information, and further improve the sorting efficiency. The mapping table may be configured according to at least one of an RRC dedicated signaling, a system broadcast message and preset configuration information sent by a network device, and optionally, priorities of the configuration mapping tables of the RRC dedicated signaling, the system broadcast message and the preset configuration information are sequentially reduced.

According to the method of the embodiment of the application, when the BSR of the first system and the BSR of the second system are included in the same BSR MAC CE, at least one first message and at least one second message are determined to be sequenced in the BSR MAC CE through the method, so that the network equipment can preferentially allocate corresponding scheduling resources for the first message with high priority and the second message with high priority according to the sequencing of the first message and the second message reported by the terminal equipment.

Fig. 5 is a flowchart of a communication method according to an embodiment of the present application, and as shown in fig. 5, the method according to the embodiment of the present application includes:

s401, the network equipment sends third information to the terminal equipment.

The third information includes carrier information of the first system.

S402, the network equipment sends fourth information to the terminal equipment.

The fourth information includes carrier information of the second system.

According to the embodiment of the application, when the vehicle networking communication system supports the first system and the second system, and the carrier information of the first system is different from the carrier information of the second system, the network equipment needs to synchronize the carrier information of the first system and the carrier information of the second system, which are supported by the network equipment, to the terminal equipment.

Optionally, the carrier information may be a carrier index or frequency point information of a carrier, where the carrier index is an index of a carrier of a first system included in the third information or an index of a carrier of a second system included in the fourth information.

Optionally, the carrier information further includes synchronization and resource configuration information corresponding to each carrier.

Optionally, the third information or the fourth information further includes system information corresponding to the carrier.

Optionally, the network device sends the third information and/or the fourth information to the terminal device through an SIB message or an RRC message.

It should be noted that there is no sequence between S401 and S402, that is, S401 may be executed before S402, or may be executed after S402, or S401 and S402 are executed simultaneously.

Optionally, the carrier information of the first system included in the first information in S101 may be the carrier information of the first system included in the third information in S401, and the carrier information of the second system included in the second information in S102 may be the carrier information of the second system included in the fourth information in S402. Therefore, the above S401 and S402 are executed before the above S101 and S102. For example, the carrier information of the first system included in the third information indicates a carrier index, so that the network device first sends the third information to the terminal device, the terminal device obtains the carrier index of the first system from the third information, then determines the corresponding relationship between the carrier index of the first system and the target address information, and sends the carrier index of the first system and the target address information included in the first information of S101 to the network device. Similarly, the network device sends the carrier information of the second system to the terminal device by including the carrier information of the second system in fourth information, and the carrier information of the second system included in the fourth information indicates a carrier index. The terminal device obtains the carrier index of the second system from the fourth information, determines the corresponding relationship between the carrier index of the second system and the target address information, and sends the carrier index of the second system and the target address information to the network device in the second information included in S102.

S403, the network device sends Downlink Control Information (DCI) to the terminal device, where the DCI includes a carrier index, for example, CIF Information, and the DCI is used to schedule a Control channel of a first link; or the terminal device sends fifth information to the network device, wherein the fifth information comprises a carrier index and target address information, and the carrier index and the target address information have a corresponding relationship; or, the terminal device sends sixth information to the network device, where the sixth information includes the carrier index.

Optionally, in this step, the network device may send DCI to the terminal device, where the DCI is used to schedule a control channel of a first link, and the first link is a direct-connection wireless communication link between the terminal device and another terminal device. The Control Channel may be a Physical link Control Channel (PSCCH) for transmitting link Control information (SCI).

Optionally, in this step, the terminal device may send fifth information to the network device, where the fifth information includes a carrier index and destination address information, and the carrier index and the destination address information have a corresponding relationship. The carrier index included in the fifth information may be an index of a carrier of the first system included in the third information or an index of a carrier of the second system included in the fourth information.

Optionally, this step may also be that the terminal device sends sixth information to the network device, for example, sends a vehicle networking common receiving interested frequency list (v2 x-commrxinterestedfeedfreqlist), where the v2 x-commrxinterestedfeedfreqlist includes carrier indexes, and the terminal device indicates to the network device which carriers are frequency points that the terminal device is interested in receiving by the terminal device through the v2 x-commrxinterestedfeedfreqlist, and the vehicle networking common receiving interested frequency list may be understood by referring to a standard text formulated by the third Generation Partnership Project (3rd Generation Partnership Project, 3 GPP).

In the embodiment of the application, the network device sends third information to the terminal device, where the third information includes carrier information of the first system, and sends fourth information to the terminal device, where the fourth information includes carrier information of the second system. Meanwhile, the network equipment sends DCI to the terminal equipment, wherein the DCI comprises a carrier index and is used for scheduling a control channel of a first link; or the terminal device sends fifth information to the network device, the fifth information includes carrier index and destination address information, the carrier index and the destination address information have corresponding relation, so that the terminal device and the network device synchronize the carrier index and the destination address information; or, the terminal device sends sixth information to the network device, where the sixth information includes a carrier index to indicate, to the network device, the received service carrier information that the terminal device is interested in.

On the basis of the foregoing embodiment, if the carrier information included in the third information and the fourth information indicates a carrier index, the following describes in detail the numbering manners of the carrier index of the first system and the carrier index of the second system with reference to a specific implementation manner.

(1) In the first case, if the third information and the fourth information are included in the same information unit.

The network equipment can include third information and fourth information in the same information unit and send the third information and the fourth information to the terminal equipment, the third information comprises a carrier index of at least one carrier supporting a first system, the fourth information comprises a carrier index of at least one carrier supporting a second system, and when the carrier indexes of different systems are sent in one information unit, the carrier indexes of different systems need to be effectively numbered, so that the terminal equipment can accurately identify the carrier index of the first system and the carrier index of the second system from the same information unit.

Optionally, the third information or the fourth information may be in the form of a container (container), for example, when the Uu port is an LTE Uu port, the fourth information is in the form of container and the third information is included in the same IE; when the Uu port is an NR Uu port, the third information takes the form of a container and the fourth information is included in the same IE.

A. In the first case, if the carrier index numbers are numbered directly, the carrier index numbering scheme includes, but is not limited to, the following three types:

in a first manner, the number of the carrier index of the first system included in the third information and the number of the carrier index of the second system included in the fourth information are adjacent in sequence.

Specifically, refer to the correspondence between the carrier of the first system and the carrier index shown in table 8, where the carrier index of the first system is sequentially numbered in the third information, and the sequential number may be an ascending number or a descending number as in table 8.

Table 8, correspondence between carrier of first system and carrier index

Carrier 1	Index 1
		Carrier 2	Index 2
Carrier 3	Index 3

Referring to the correspondence between the carrier of the second system and the carrier index shown in table 9, the carrier index of the second system is sequentially numbered in the fourth information, and the sequential number may be an ascending number or a descending number as shown in table 9.

Table 9 correspondence between carriers of the second system and carrier indexes

Carrier 3	Index 4
		Carrier wave 5	Index 5

As can be seen from tables 8 and 9, the numbers of the carrier indexes of the first system included in the third information and the numbers of the carrier indexes of the second system included in the fourth information are adjacent in sequence, for example, the numbers of the carrier indexes of the first system included in the third information are 1 to 3, and the numbers of the carrier indexes of the second system included in the fourth information are 4 to 5.

Table 8 and table 9 are merely examples, and optionally, the carrier indexes of the second system included in the fourth information may be numbered first, and then the carrier indexes of the first system included in the third information may be numbered, for example, the carrier indexes of the second system included in the fourth information are numbered 1 to 2, and the carrier indexes of the first system included in the third information are numbered 3 to 5.

Optionally, the numbers of the carrier indexes of the first system included in the third information may also be sorted in a descending order, for example, starting from a preset value 100, the numbers of the carrier indexes of the first system included in the third information are sorted in a descending order from 100 to 98, and the carrier cables of the second system included in the fourth information are sorted in a descending order from 97 to 96. Or, the numbers of the carrier indexes of the second system included in the fourth information are arranged in a descending order from 100 to 99, and then the numbers of the carrier indexes of the first system included in the third information are arranged in a descending order from 98 to 96.

In a second mode, the number of the carrier index of the first system included in the third information and the number of the carrier index of the second system included in the fourth information are respectively numbered sequentially, and a difference between the minimum number of the carrier index of the first system included in the third information and the minimum number of the carrier index of the first system included in the fourth information is equal to K, where K is a positive integer.

As shown in table 8, the numbers of the carrier indexes of the first system included in the third information are sequentially numbered according to the sorting order of the carriers of the first system, and the sequential numbers may be ascending numbers or descending numbers as shown in table 8.

In this application, a difference between the minimum number of the carrier index of the first system included in the third information and the minimum number of the carrier index of the second system included in the fourth information is equal to a positive integer K.

It should be noted that the value of K should ensure that the number of the carrier index of the first system included in the third information and the number of the carrier index of the second system included in the fourth information are not overlapped. For example, if the third information includes the number ranges of the carrier indexes of the first system from 1 to 3, K should be a positive integer greater than or equal to 3, for example, minimum 3.

For example, assuming that K is 10, on the basis of table 9, the number of the carrier index of the second system included in the fourth information of the present application may be as shown in table 10, where the carrier index of the second system is sequentially numbered. The sequence number may be an ascending sequence number or a descending sequence number as shown in table 10.

Table 10 correspondence between carriers of second system and carrier index

Carrier 3	Index 11
		Carrier wave 5	Index 12

As can be seen from tables 8 and 9, the difference between the minimum number 1 of the carrier index of the first system included in the third information and the minimum number 11 of the carrier index of the second system included in the fourth information is equal to a positive integer K equal to 10.

Optionally, the terminal device may configure the K in different ways, for example, the terminal device is configured through at least one of radio resource control RRC dedicated signaling, system broadcast message and preset configuration information sent by the network device.

Optionally, the RRC dedicated signaling, the system broadcast message, and the preset configuration information have configuration priorities, for example, the configuration priorities of the RRC dedicated signaling, the system broadcast message, and the preset configuration information are sequentially reduced. Thus, when the terminal device receives the RRC dedicated signaling, the system broadcast message, and the preset configuration information at the same time, the value of K may be determined according to the configuration priority among the three devices, for example, the value of K is determined according to the RRC dedicated signaling.

In a third manner, the number of the carrier index of the first system included in the third information and the number of the carrier index of the second system included in the fourth information are respectively numbered sequentially, and the minimum number of the carrier index of the first system included in the third information is equal to the minimum number of the carrier index of the second system included in the fourth information, and the DCI, the fifth information, or the sixth information further includes system information corresponding to the carrier index.

As shown in table 8, the third information includes the number sequence number of the carrier index of the first system.

Meanwhile, the fourth information includes the serial number of the carrier index of the second system, and the third information includes the minimum number of the carrier index of the first system and the fourth information includes the minimum number of the carrier index of the second system which are equal.

Exemplarily, the fourth information includes a correspondence between the carrier of the second system and the carrier index, which is shown in table 11, where the numbers of the carrier indexes of the second system included in the fourth information are sequentially numbered in the fourth information, and the minimum number of the carrier index of the second system included in the fourth information is equal to the minimum number of the carrier index of the first system included in the third information, and is, for example, 1.

Table 11, correspondence between carrier of second system and carrier index

Carrier 3	Index 1
		Carrier wave 5	Index 2

As can be seen from tables 8 and 11, the number of the carrier index of the first system included in the third information and the number of the carrier index of the second system included in the fourth information are sequentially numbered from a certain preset value (e.g. 1).

In this manner, the number of the carrier index of the first system included in the third information and the number of the carrier index of the second system included in the fourth information overlap, for example, index1 corresponds to both carrier 1 supporting the first system and carrier 3 supporting the second system. In this way, when the network device transmits the third information and the fourth information to the terminal device, the terminal device cannot determine which carrier corresponds to the index 1.

In order to solve the above technical problem, the third information and the fourth information further include system information corresponding to the carrier, for example, the third information includes system information of the first system, and the fourth information includes system information of the second system.

Optionally, in order to save downlink resources, the system information corresponding to the carrier index may be represented by one bit (bit).

B. In the first case, if the number of the carrier index is determined according to the number range of the carrier index, the numbering manner of the carrier index includes, but is not limited to, the following:

in a first manner, the number range of the carrier index of the first system included in the third information and the number range of the carrier index of the second system included in the fourth information are sequentially adjacent to each other.

For example, it is assumed that the third information includes carrier indexes of the first system in a number range of 1 to 50, and the fourth information includes carrier indexes of the second system in a number range of 51 to 100. The third information includes the numbers of the carrier indexes of the first system, which are numbered in the number range 1 to 50, for example, the numbers are sequentially numbered, or the numbers are numbered according to a preset number rule. The fourth information includes numbers of the carrier indexes of the second system, which are numbered in the number range 51 to 100, for example, sequential numbers, or numbers according to a preset numbering rule.

It should be noted that the number range of the carrier index of the first system included in the third information and the number range of the carrier index of the second system included in the fourth information may be adjusted according to actual needs.

In a second mode, the number of the carrier index of the first system included in the third information and the number of the carrier index of the second system included in the fourth information are sequentially numbered in respective number ranges, and a difference between a maximum number of the number range of the carrier index of the first system included in the third information and a minimum number of the number range of the carrier index of the first system included in the fourth information is equal to Q, where Q is a positive integer.

In this implementation manner, the difference Q between the maximum number in the number range of the carrier index of the first system included in the third information and the minimum number in the number range of the carrier index of the first system included in the fourth information is a positive integer greater than or equal to 1.

Optionally, the size of the number range of the carrier index of the first system included in the third information may be the same as or different from the size of the number range of the carrier index of the first system included in the fourth information, and is specifically determined according to actual needs.

For example, assuming that Q is 50, the third information includes the number ranges 1 to 50 of the carrier indexes of the first system, and the fourth information includes the number ranges 100 to 140 of the carrier indexes of the second system. Thus, the carrier indexes of the first system included in the third information are sequentially numbered in the number range of 1 to 50, and the carrier indexes of the second system included in the fourth information are sequentially numbered in the number range of 100 to 140.

Optionally, Q may be configured by the terminal device through at least one of radio resource control RRC dedicated signaling from the network device, a system broadcast message from the network device, and preset configuration information. Optionally, the priority of the configuration Q of the RRC dedicated signaling, the system broadcast message, and the preset configuration information is sequentially reduced.

Optionally, in order to explicitly indicate that carrier information included in the third information is of the first system, and carrier information included in the fourth information is of the second system, the third information may include system information of the first system, or the fourth information further includes system information corresponding to the carrier.

In a third manner, the number of the carrier index of the first system included in the third information and the number of the carrier index of the second system included in the fourth information are sequentially numbered in respective number ranges, and the minimum number of the number range of the carrier index of the first system included in the third information is equal to the minimum number of the number range of the carrier index of the second system included in the fourth information. The DCI, the fifth information, or the sixth information may further include system information corresponding to the carrier index.

For example, assuming that the number range of the carrier index of the first system included in the third information is 1 to 50, the number range of the carrier index of the second system included in the fourth information is 1 to 100, and the minimum number 1 of the number range of the carrier index of the first system included in the third information and the minimum number 1 of the number range of the carrier index of the second system included in the fourth information are equal. And the carrier indexes of the first system are sequentially numbered within the number range of 1 to 50, and the carrier indexes of the second system are sequentially numbered within the number range of 1 to 100.

In this manner, there is a problem that the same index number corresponds to two carrier indexes, and in order to solve this problem, system information corresponding to the carrier index is further included in the DCI or the fifth information or the sixth information.

In the application, when the third information and the fourth information are included in the same information unit, the number of the carrier index of the first system included in the third information and the number of the carrier index of the second system included in the fourth information are renumbered in the above manner, so that the terminal device and the network device can distinguish the carriers of the first system and the second system accurately, and a foundation is laid for subsequent resource scheduling.

(2) In the second case, if the third information and the fourth information are included in different information units.

The terminal equipment can include the third information and the fourth information in different information units and send the third information and the fourth information to the network equipment, and therefore time-sharing sending of the third information and the fourth information is achieved.

A. In the second case, the carrier indexes of the destination address information included in the third information and the fourth information are numbered in the following three ways:

The specific implementation process of this method can be shown in table 8 and table 9, and is not described herein again.

In a second mode, the number of the carrier index of the first system included in the third information and the number of the carrier index of the second system included in the fourth information are respectively numbered sequentially, and a difference between the minimum number of the carrier index of the first system included in the third information and the minimum number of the carrier index of the second system included in the fourth information is equal to L, where L is a positive integer.

The specific implementation process of this method can be shown in table 8 and table 10, and will not be described herein again.

Optionally, the difference L may be configured by the terminal device through at least one of a radio resource control RRC dedicated signaling from the network device, a system broadcast message from the network device, and preset configuration information. Optionally, the priority of the configuration L of the RRC dedicated signaling, the system broadcast message, and the preset configuration information is sequentially reduced.

The specific implementation process of this method can be shown in table 8 and table 11, and is not described herein again.

B. In the second case, if the number of the carrier index is determined according to the number range of the carrier index, the numbering manner of the carrier index includes, but is not limited to, the following:

For example, it is assumed that the third information includes carrier indexes of the first system in a number range of 1 to 50, and the fourth information includes carrier indexes of the second system in a number range of 51 to 100. The carrier indexes of the first system included in the third information are numbered in the number range 1 to 50, for example, are sequentially numbered, or are numbered according to a preset number rule. The fourth information includes carrier indexes of the second system numbered within a number range 51 to 100, such as sequential numbers, or numbers according to a preset numbering rule.

In a second mode, the number of the carrier index of the first system included in the third information and the number of the carrier index of the second system included in the fourth information are sequentially numbered in respective number ranges, and a difference between a maximum number of the number range of the carrier index of the first system included in the third information and a minimum number of the number range of the carrier index of the second system included in the fourth information is equal to S, where S is a positive integer.

In this implementation manner, the difference S between the maximum number in the number range of the carrier index of the first system included in the third information and the minimum number in the number range of the carrier index of the second system included in the fourth information is a positive integer greater than or equal to 1.

Optionally, the size of the number range of the carrier index of the first system included in the third information may be the same as or different from the size of the number range of the carrier index of the second system included in the fourth information, and is specifically determined according to actual needs.

For example, assuming that S is 50, the third information includes the number ranges 1 to 50 of the carrier indexes of the first system, and the fourth information includes the number ranges 100 to 140 of the carrier indexes of the second system. Thus, the carrier indexes of the first system included in the third information are sequentially numbered in the number range of 1 to 50, and the carrier indexes of the first system included in the fourth information are sequentially numbered in the number range of 100 to 140.

Optionally, the S may be configured by the terminal device through at least one of a radio resource control RRC dedicated signaling from the network device, a system broadcast message from the network device, and preset configuration information.

Wherein, the priority of the configuration S of the RRC dedicated signaling, the system broadcast message and the preset configuration information is reduced in sequence.

In the application, when the third information and the fourth information are included in different information units, the number of the carrier index of the first system included in the third information and the number of the carrier index of the second system included in the fourth information are renumbered in the above manner, so that the terminal device and the network device can distinguish the carriers of the first system and the second system accurately, and a foundation is laid for subsequent resource scheduling.
