The communication method proposed in this application will be described in detail below in conjunction with specific embodiments.

FIG. 2 is a flowchart of a communication method provided by an embodiment of the application. As shown in FIG. 2, the communication method of an embodiment of the application includes:

S101. The terminal device sends the first information to the network device.

The first information includes carrier information of the first standard and target address information, and the carrier information of the first standard has a corresponding relationship with the target address information.

S102: The terminal device sends second information to the network device.

The second information includes carrier information of the second standard and target address information, and the carrier information of the second standard has a corresponding relationship with the target address information.

When the terminal device requests the network device to schedule the transmission resources corresponding to the service of interest, the terminal device first reports its own carrier information and target address information to the network device.

Optionally, when the carrier information and target address information are updated, the terminal device re-reports its own carrier information and target address information to the network device.

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

Optionally, if the foregoing service is a broadcast service, the target address information is the service identification information or the layer 2 target address information obtained by the conversion of the service identification. If the above-mentioned service is a multicast service, the target address information is group identification information. If the foregoing service is a unicast service, the target address information is the identification information of the opposite terminal device.

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

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

It can be seen from FIG. 1 that the car networking communication system involved in the embodiment of the present application supports the first and second standards. The carrier information of the first standard has a corresponding relationship with the target address information, and the carrier information of the second standard has a corresponding relationship with the target address information. The corresponding relationship between the carrier information of the first standard and the target address information is different from the corresponding relationship between the carrier information of the second standard and the target address information.

Exemplarily, assuming that the first standard is LTE, Table 1 shows the correspondence between the carrier information of the first standard and the target address information, that is, the mapping between the carrier of the first standard and the vehicle networking target address information list (v2x-destinationInfoList) relationship.

As shown in Table 1a, the carrier information of the first standard includes carrier 1, carrier 2, and carrier 3. The destination address information includes: destination ID 1, destination ID 2, destination ID 3, destination ID 4, destination ID 5, destination ID 6 . Among them, carrier 1 has a corresponding relationship with destination ID 1, destination ID 2, destination ID 3, carrier 2 has a corresponding relationship with destination ID 3, destination ID 4, destination ID 5, and carrier 3 has a corresponding relationship with destination ID 3, destination ID 5, destination ID 6 has a corresponding relationship.

Table 1a, the correspondence between the carrier information of the first standard and the target address information

It should be noted that Table 1a is only an example of the correspondence between the carrier information of the first standard and the target address information. Optionally, as shown in Table 1b, the correspondence between the carrier information of the first standard and the target address information is also Including a destination ID corresponds to a carrier list, and a carrier list includes one or more carriers. For example, the destination ID3 of the first standard has a corresponding relationship with carrier 1, carrier 2 and carrier 3, and the destination ID 1 of the first standard corresponds to the carrier Carrier 1 has a corresponding relationship.

Exemplarily, assuming that the second standard is NR, Table 2a is the correspondence relationship between the carrier information of the second standard and the destination address information, that is, the mapping relationship between the carrier of the second standard and the v2x-destinationInfoList.

As shown in Table 2a, the carrier information of the second standard includes carrier 3 and carrier 4, and the destination address information includes: destination ID 3, destination ID 7, destination ID 8, destination ID 10. Among them, carrier 3 has a corresponding relationship with destination ID 3, destination ID 7, and destination ID 8, and carrier 4 has a corresponding relationship with destination ID 8 and destination ID 10.

Table 2a, the corresponding relationship between the carrier information of the second standard and the target address information

It should be noted that Table 2a is only an example of the correspondence between the carrier information of the second standard and the target address information. Optionally, as shown in Table 2b, the correspondence between the carrier information of the second standard and the target address information is also Including a destination ID corresponds to a carrier list, and a carrier list includes one or more carriers. For example, the destination ID8 of the second standard has a corresponding relationship with carrier 3 and carrier 4, and the destination ID 1 of the second standard has a corresponding relationship with carrier 1. relationship.

Table 2b, the correspondence between the carrier information of the second standard and the target address information

From Table 1a, Table 1b, Table 2a, and Table 2b, it can be seen that the carriers corresponding to the first and second standards can be the same. For example, carrier 3 supports both the first and second standards; the first and second standards correspond to The destination address can also be the same, for example, destination ID 3 supports both the first standard and the second standard.

From Table 1a, Table 1b, Table 2a and Table 2b, the correspondence between carrier information and target address information includes two ways. Method 1 is: one carrier information corresponds to one target address information list, and one target address information list includes one or Multiple destination address information, for example, the destination address information list corresponding to carrier 1 supporting the first standard in Table 1a is destination ID 1, destination ID 2, destination ID 3. Method 2: One target address information corresponds to one carrier information list, and one carrier information list includes one or more carrier information. For example, the carrier information list corresponding to destination ID 3 in Table 1b is carrier 1 and carrier 2 that support the first standard. And carrier 3, that is, destination ID 3 can be scheduled on any one of carrier 1, carrier 2, and carrier 3 that supports the first standard. Optionally, in method 2, the carrier information included in the carrier information list corresponding to the destination address information also includes the standard information corresponding to the carrier, for example, as shown in Table 1b and Table 2b, the carrier information list corresponding to destination ID 3 includes Carrier 1, carrier 2, and carrier 3 supporting the first standard, and carrier 3 supporting the second standard.

It can be seen from the above that the correspondence between the carrier information of the first system and the target address information is different from the correspondence between the carrier information of the second system and the target address information. Therefore, the terminal device combines the carrier information of the first system with the target address information and the second system. The carrier information and target address information of the standard are sent to the network equipment to ensure that the network equipment can accurately distinguish the carrier information and target address information of the first standard and the carrier information and target address information of the second standard to ensure accurate scheduling of subsequent services.

In a possible implementation manner, the terminal device includes the carrier information of the first standard and the target address information in the first information unit IE and sends to the network device, and includes the carrier information and target address information of the second standard in the second information. The unit IE is sent to the network device. For example, the following program code can represent an IE, which includes carrier information (CarrierFreqCommTx) and destination address information (v2x-DestinationInfolist) of the corresponding standard:

When the network device receives the first IE, it obtains the carrier information of the first standard and the target address information from the first IE. When the network device receives the second IE, it obtains the carrier of the second standard from the second IE. Information and target address information.

The above-mentioned first IE or second IE may be included in the sidelink user information (SUI) reported by the terminal device to the network device. For example, the first IE is included in the LTE standard car networking side chain public receiving resource request ( SL-V2X-CommTxResourceReq-LTE) sent to the network equipment. The second IE is included in the SL-V2X-CommTxResourceReq-NR of the NR standard and sent to the network device.

Optionally, the first IE and the second IE indicate the standard information corresponding to the carrier. One possible way is to indicate by implicit information, such as the names of different IEs, to indicate the standard information supported by the carrier within the IE ( For example, SL-V2X-CommTxResourceReq-LTE and SL-V2X-CommTxResourceReq-NR); another possible way is to indicate through display information, for example, the specific format information supported by each carrier in the IE can be indicated by a bit. Instructions. In this way, when the network device schedules a carrier, it can determine whether it is the target address information on the carrier corresponding to the first standard or the target address information on the carrier corresponding to the second standard according to the standard information corresponding to the carrier information.

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

Optionally, the foregoing first information or second information may be in the form of a container. For example, as shown in the following program code, the second information may be in the form of SL-V2X-CommTxResourceReq-container-r16:

Optionally, in this embodiment, the standard information corresponding to the carrier can be indicated. For example, the standard information supported by each carrier is indicated by a bit, so that when the network device schedules the carrier, it can be based on the standard corresponding to the carrier information. Information to determine whether to schedule the target address information on the carrier corresponding to the first standard or to schedule the target address information on the carrier corresponding to the second standard.

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

In this application, the terminal device carries the carrier information corresponding to the first standard and the second standard and the target address information in the same IE and sends it to the network device. This saves air interface overhead or transfers the carrier information corresponding to the first standard and the second standard. The information and the target address information are carried in different IEs and sent to the network device, which can increase the flexibility of sending carrier information and target address information corresponding to the first and second standards.

Further, the terminal equipment of this application sends the carrier information and target address information corresponding to the first and second standards to the network equipment to ensure that the network equipment can be accurately scheduled based on the carrier information and target address information of the first standard when the network equipment is scheduled later. The carrier of the first standard, based on the carrier information of the second standard and the target address information, accurately schedules the carrier of the second standard, thus solving the problem that network equipment cannot schedule on the correct carrier, thereby improving the support for the first standard and The communication reliability of the second-mode IoV communication system.

It can be seen from Table 1a and Table 2a that carrier 3 supports both the first standard (such as LTE) and the second standard (such as NR), but carrier 3 has different target address information about the first standard and the second standard. Therefore, when the network device schedules carrier 3, it needs to specify whether to schedule target address information on carrier 3 corresponding to LTE or to schedule target address information on carrier 3 corresponding to NR.

S103: The terminal device sends the BSR of the first link to the network device.

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.

As shown in Figure 1, the above-mentioned first link is a wireless direct communication link between a terminal device and other terminal devices. Optionally, the wireless direct communication interface between terminal devices can be defined as a PC5 port.

It should be noted that the above S103 is executed after the above S101 and S102.

In the actual service transmission stage, the terminal device sends the first link buffer status report (Sidelink Buffer Status Report, Sidelink BSR) to the network device, and the network device learns the buffer volume of the service to be sent by the terminal device on the PC5 port through the BSR.

The BSR includes a destination address information index (Destination index), and the destination address information index 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 can correspond to a target address information list, a target address information list can include one or more target address information, and a target address information list can have one target address information. The address information index corresponds to it.

In the existing car networking communication system that supports one format, the target address information index is numbered according to the sort order of the target address information. However, when the car networking communication system supports two formats, in order to enable the network device to accurately identify the terminal device Whether the target address information index carried in the reported BSR is of the first system or the second system, it is necessary to renumber the indexes of the target address information of different systems.

On the basis of the embodiment shown in FIG. 2, the numbering method of the target address information index of the target address information included in the first information and the second information will be described in detail below in combination with different implementations. It should be noted that this The numbering method of the target address information index involved in the application embodiment includes but is not limited to the following methods.

(1) In the first case, the first information and the second information are included in the same information element (Information Element, IE), for example, both the first information and the second information are included in SL-V2X-ComTxResourceReq and sent to the network equipment.

Optionally, the aforementioned first information or second information may be in the form of a container. For example, when the Uu port is an LTE Uu port, the second information is in the form of a container and the first information is included in the same IE: When the Uu port is an NR Uu port, the first information is in 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 and the second information in one information unit, the above-mentioned first information and/or second information may also include standard information corresponding to the carrier wave. For example, the first information includes the standard information of the first standard, but the second information does not include the standard information of the second standard. In this way, the network device can obtain the first information corresponding to the first standard from the information unit, and save the remaining information. The information is determined to be the second information corresponding to the second standard. Alternatively, the second information includes the standard information of the second standard, but the first information does not include the standard information of the first standard, so that the network device can obtain the second information corresponding to the second standard from the information unit, and the remaining information Determine the first information corresponding to the first standard. Or, the first information includes the standard information of the first standard, and the second information includes the standard information of the second standard. In this way, the network device can obtain the first information corresponding to the first standard and the corresponding information corresponding to the second standard from the information unit. Second information.

A. In the first case, if the number of the target address information index is directly numbered, the numbering methods of the target address information index include but are not limited to the following three:

Manner 1: The number of the target address information index of the target address information included in the first information is adjacent to the number of the target address information index of the target address information included in the second information.

Exemplarily, on the basis of the foregoing Table 1a, the corresponding relationship between the carrier information, target address information, and target address information index of the first standard is shown in Table 3, where the number of the target address information index of the first standard is according to the first standard. The sequence of the target address information in a message is numbered sequentially, and the sequence number can be ascending number as shown in Table 3 or descending number.

Table 3 Correspondence between carrier information, target address information, and target address information index of the first standard

Exemplarily, on the basis of the foregoing Table 2a, the correspondence between the carrier information, target address information, and target address information index of the second standard is shown in Table 4, where the number of the target address information index of the second standard is according to the Second, the target address information in the information is arranged in sequence. The sequence number can be ascending number as shown in Table 4, or it can be descending number.

Table 4 Correspondence between carrier information, target address information, and target address information index of the second standard

It can be seen from Table 3 and Table 4 that the number of the target address information index of the target address information included in the first information is adjacent to the number of the target address information index of the target address information included in the second information. For example, the first information includes The number of the target address information index of the target address information is 1 to 9, and the number of the target address information index of the target address information included in the second information is 10 to 14.

Table 3 and Table 4 are just examples. Optionally, the target address information index of the target address information included in the second information may be numbered first, and then the target address information index of the target address information included in the first information may be numbered. For example, the number of the target address information index of the target address information included in the second information is 1 to 5, and the number of the target address information index of the target address information included in the first information is 6 to 14.

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

Manner 2: 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 sequentially numbered, and the first information The difference between the minimum number of the target address information index included in the target address information and the minimum number of the target address information index included in the second information is equal to M, where M is a positive integer.

Continuing to refer to Table 3, the number of the target address information index of the target address information included in the first information is sequentially numbered according to the sequence of the target address information included in the first information, and the sequence number may be an ascending number as shown in Table 3. , Or it can be in descending order.

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

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

Exemplarily, assuming that the foregoing M is 99, on the basis of the foregoing Table 2, the correspondence between the carrier information of the second standard, the target address information, and the target address information index included in the second information may be as shown in Table 5, where: The numbers of the target address information index of the second standard are arranged in order according to the order of the target address information in the second information. The sequence number can be ascending number as shown in Table 5, or it can be descending number.

Table 5. Correspondence between carrier information, target address information, and target address information index of the second standard

It can be seen from Table 3 and Table 5 that 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 Positive integer M=99.

Optionally, the terminal device can configure the above M in different ways, for example, the terminal device controls at least one of RRC dedicated signaling through radio resource control from the network device, system broadcast message from the network device, and preset configuration information To configure.

Optionally, the foregoing RRC dedicated signaling, system broadcast message, and preset configuration information have configuration priorities. For example, the configuration priorities of RRC dedicated signaling, system broadcast messages, and preset configuration information are sequentially reduced. In this way, when the terminal device obtains the RRC dedicated signaling, system broadcast message, and preset configuration information at the same time, the value of M can 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 RRC dedicated signaling, system broadcast messages, and preset configuration information at the same time, the configuration information with higher priority is used to cover the configuration information with lower priority. For example, the terminal device receives the information from the network device in the first second. When the system broadcast message receives the RRC dedicated signaling from the network device in the 1.5 second, the terminal device uses the RRC dedicated signaling to cover the system broadcast message, that is, the terminal device determines the value of M according to the RRC dedicated signaling.

Manner 3: 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 sequentially numbered, and the first information The minimum number of the target address information index of the target address information included in one piece of information is equal to the minimum number of the target address information index of the target address information included in the second information.

Continuing to refer to Table 3, the numbering of the target address information index of the target address information included in the first information is sequentially numbered according to the sequence of the target address information included in the first information.

At the same time, the numbering of the target address information index of the target address information included in the second information is sequentially numbered according to the sequence 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 foregoing Table 2a, the correspondence between the carrier information, target address information, and target address information index of the second standard is shown in Table 6, where the second information includes the target address information of the target address information The index is numbered sequentially according to the sequence of the target 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, target address information, and target address information index of the second standard

As can be seen from Table 3 and Table 6, 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 start from a certain preset value (for example, 1) , And their respective sequence numbers.

In this manner, the number of the target address information index of the target address information included in the first information overlaps with the number of the target address information index of the target address information included in the second information. For example, destination index 3 may be the destination ID in Table 3. The destination address information index of destination ID 3, the carrier corresponding to destination ID 3 is carrier 1, carrier 2, and carrier 3 of the first standard; it can also be the destination address information index of destination ID 8 in Table 6, and the carrier corresponding to destination ID 8 is the first carrier. Two-standard carrier 3 and carrier 4. In this way, 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 ID 3 under the first standard or the destination ID 8 under the second standard, and thus cannot determine the destination index. 3 corresponds to the carrier corresponding to the standard.

In order to solve the above technical problems, the BSR in the embodiment of the present application also includes the standard information corresponding to the carrier. For example, the BSR includes destination index 3 and the first standard information, so that the network device receives the BSR from the information shown in Table 3. In the correspondence relationship between carrier information and destination address information, look for the destination index 3 corresponding to destination ID 3, and destination ID 3 corresponds to carrier 1, carrier 2, and carrier 3 of the first standard, and the network equipment can determine the destination index 3 in the above BSR The corresponding carriers are carrier 1, carrier 2, and carrier 3 of the first standard, and subsequent network equipment can schedule corresponding resources for the terminal equipment on any one of these three carriers.

Optionally, in order to save uplink resources, the standard information corresponding to the target address information index included in the above-mentioned BSR may be represented by one bit.

B. In the first case, if the number of the target address information index is determined according to the number range of the target address information index, the numbering methods of the target address information index include but are not limited to the following three:

Manner 1: The number range of the target address information index of the target address information included in the first information and the number range of the target address information index of the target address information included in the second information are adjacent in order.

Exemplarily, suppose that the number range of the target address information index of the target address information included in the first information is 1 to 50, and the number range of the target address information index of the target address information included in the second information is 51 to 100. Wherein, the target address information index of the target address information included in the first information is numbered in a numbering range of 1 to 50, such as sequential numbers, or numbered according to a preset numbering sequence. The target address information index of the target address information included in the second information is numbered in a number range of 51 to 100, such as sequential numbers, or numbered according to a preset numbering sequence.

It should be noted that the size of the number range of the target address information index of the target address information included in the first information and the size of the number range of the target address information index of the target address information included in the second information can be adjusted according to actual needs.

Manner 2: 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 sequentially numbered within their respective number ranges, And the difference between the largest number in the number range of the target address information index of the target address information included in the first information and the smallest number in the number range of the target address information index of the target address information included in the second information The value is equal to P, which is a positive integer.

In this implementation manner, the difference P between the largest number in the number range of the target address information index of the target address information included in the first information and the smallest number in the number range of the target address information index of the target address information included in the second information, the P 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 and the size of the number range of the target address information index of the target address information included in the second information may be the same or different. The actual needs to be determined.

Exemplarily, assuming that P=50, the number range of the target address information index of the target address information included in the first information is 1 to 50, and the number range of the target address information index of the target address information included in the second information is 100 to 140 . In this way, the target address information index of the target address information included in the first information is sequentially numbered in the numbering range 1 to 50, and the target address information index of the target address information included in the second information is sequentially numbered in the numbering range 100 to 140.

Optionally, the foregoing P 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 P of the foregoing RRC dedicated signaling, system broadcast message, and preset configuration information is sequentially reduced.

Manner 3: 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 sequentially numbered within their respective number ranges, And the smallest number in the number range of the target address information index of the target address information included in the first information is equal to the smallest number in the number range of the target address information index of the target address information included in the second information . The first information or the second information may also include standard information corresponding to the carrier index.

For example, assuming that the number range of the target address information index number of the target address information included in the first information is 1 to 50, the number range of the target address information index number of the target address information included in the second information is 1 to 100, The first information and the second information include the smallest number in the number range of the number range of the target address information index of the target address information, for example, both are 1. And the target address information index of the target address information included in the first information is sequentially numbered in the numbering range 1-50, and the target address information index of the target address information included in the second information is sequentially numbered in the numbering range 1-100.

In this manner, there is a problem that the same target address information index corresponds to two standard carriers in the number. To solve this problem, the standard information corresponding to the carrier is also included in the first information or the second information.

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

In this 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 target address information included in the second information are indexed in the above manner. The number of the target address information index is renumbered, so that when the network device receives the target address information index in the BSR sent by the terminal device, it can accurately determine the carrier corresponding to the system corresponding to the target address information index, and implement subsequent operations on the carrier. Perform resource scheduling.

(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, and the second standard corresponding to the second information is NR. In this way, the terminal device can include the first information in SL-V2X-ComTxResourceReq-LTE and send it to the network device, and send the second The information is included in the SL-V2X-ComTxResourceReq-NR and sent to the network device.

A. In the second case, if the number of the target address information index is directly numbered, the numbering methods of the target address information index include but are not limited to the following three:

For the specific implementation process of this manner, refer to the above Table 3 and Table 4, which will not be repeated here.

Manner 2: 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 sequentially numbered, and the first information The difference between the minimum number of the target address information index of the target address information included in one piece of information and the minimum number of the target address information index of the target address information included in the second information is equal to R, where R is a positive integer .

For the specific implementation process of this manner, refer to the above Table 3 and Table 5, which will not be repeated here.

Optionally, the aforementioned 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, system broadcast message, and preset configuration information is sequentially reduced.

For the specific implementation process of this method, refer to the above Table 3 and Table 6, which will not be repeated here.

B. In the second case, if the number of the target address information index is determined according to the number range of the target address information index, the numbering methods of the target address information index include but are not limited to the following two:

For the specific implementation process of this manner, reference may be made to the first manner under the B example in the first case above, and details are not described herein again.

For the specific implementation process of this manner, refer to the second manner under the example B in the first case above, which is not repeated here. Manner 3: 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 sequentially numbered within their respective number ranges, And the smallest number in the number range of the target address information index of the target address information included in the first information is equal to the smallest number in the number range of the target address information index of the target address information included in the second information The first information or the second information may also include standard information corresponding to the carrier index.

For the specific implementation process of this manner, reference may be made to the third manner under the example B in the first case above, which is not repeated 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 target address information included in the second information are indexed in the above manner. The number of the target address information index is renumbered, so that when the network device receives the target address information index in the BSR sent by the terminal device, it can accurately determine the carrier corresponding to the system corresponding to the target address information index, and implement subsequent operations on the carrier Perform resource scheduling.

In this way, after the network device receives the BSR reported by the terminal device, it 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 the subsequent scheduling of the network device On the corresponding carrier of the standard.

For example, suppose that the BSR includes Destination index 2 and Destination index 7, where Destination index 2 is the index of destination ID 2 in the first message. From Table 1, it can be seen that destination ID 2 of the first standard corresponds to carrier 1, so that the network The device can determine carrier 1 according to the Destination index 2, and then subsequently perform scheduling on carrier 1 corresponding to the first standard. Destination index 7 is the index of the destination ID 3 in the second information. It can be seen from Table 2 that the destination ID 3 of the second standard corresponds to carrier 3, and carrier 3 supports both the first standard and the second standard, and destination ID 3 corresponds to It is the second information of the second standard. In this way, the network device can determine the carrier 3 of the second standard according to the Destination index 7, and then subsequently perform scheduling on the carrier 3 corresponding to the second standard.

The target address information index included in the BSR is the index of the target address information in the first information or the index of the target address information in the second information, and the first information corresponds to the first standard, and the second information corresponds to the second standard. In other words, the target address information index in this step includes the standard information explicitly or implicitly, so that after the network device obtains the target address information index, it can accurately find the target from the received table 1a or table 2a. The address information index corresponds to the carrier information corresponding to the system, thereby avoiding the problem that the network device cannot learn the carrier corresponding to the system corresponding to the target address information index in the BSR, and the network device cannot perform scheduling on the correct carrier.

In the communication method provided by the embodiments of the present application, the terminal device sends first information including carrier information of the first standard and target address information to the network device, and the carrier information of the first standard has a corresponding relationship with the target address information, and sends it to the network The device sends second information including carrier information of the second standard and target address information, and the carrier information of the second standard has a corresponding relationship with the target address information. Next, the terminal device sends the BSR of the first link to the network device. The BSR includes a target address information index. The target address information index is the index of the target address information in the first message or the index of the target address information in the second message. index. It is ensured that after the terminal device sends the carrier information and target address information of the first standard and the carrier information and target address information of the second standard to the network device, when the network device receives the target address in the first link BSR sent by the terminal device After the information is indexed, the carrier information corresponding to the target address information index can be accurately obtained from the carrier information and target address information of the first standard or the carrier information and target address information of the second standard according to the target address information index, which solves the problem of network equipment. The problem of not being able to perform scheduling on the correct frequency, thereby improving the communication reliability of the car networking communication system supporting the first and second standards.

FIG. 3 is a flowchart of a communication method provided by an embodiment of this application. As shown in FIG. 3, the communication method of an embodiment of this application includes:

S201: The terminal device determines the BSR of the first standard of the first link.

The BSR of the first standard may include at least one piece of first information, and the first information may include an index of target address information, LCG information, and buffer size (BS) information.

Wherein, the information about the size of the buffer area has a corresponding relationship with the index of the target address information and the LCG information.

S202: The terminal device determines the BSR of the second standard of the first link.

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

It should be noted that although the first information and the second information of the embodiment of the present application are named the same as the first information and the second information of the embodiment shown in FIG. 2, they are different concepts.

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

The index of the target address information is to select one from one or more indexes associated with the target address information under the corresponding standard. For example, for destination ID 3, both the first standard and the second standard are supported. When the buffer size BS of the corresponding service under the first standard is determined to be reported, the associated index destination index 1, in Table 3 corresponding to the first standard is determined. Select one of destination index 4 and destination index 7 as the destination ID 3 corresponds to the destination index in the first information; when it is determined to report the BS corresponding to the service under the second standard, the associated index destination is obtained from Table 4 corresponding to the second standard Index 10 as the destination ID 3 corresponds to the destination index in the second information.

Optionally, the above-mentioned 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 this application, for different standards, the corresponding BSRs are different. Assume that Figure 4 is a BSR of the first standard. As shown in Figure 4, the BSR of the first standard includes one or more first information. Including the target address information index and LCG information, buffer size BS information. 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 logical channels (Logical Channel, LCH). According to the above corresponding relationship, it can be known that an index of target address information and an LCG information uniquely determine a buffer size BS, and the BS is the sum of the data volume of data to be transmitted on all LCHs in the LCG. For example, the index 1 of the target address information and the LCG 1 correspond to a BS 1. The BS 1 indicates the total amount of data to be transmitted on all LCHs in the LCG 1 of the index 1 of the target address information; the index 2 and LCG 2 of the target address information Corresponding to a BS 2, the BS 2 indicates the total amount of data to be transmitted on all LCHs in the LCG 2 of the index 2 of the target address information.

Optionally, FIG. 4 may also be a BSR of the second standard. As shown in FIG. 4, the BSR of the second standard includes one or more second information. The second information includes the index of the target address information and the LCG information, cache Zone size BS information. 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 insufficient, 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 reporting priority is lower. High first information and/or second information.

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

S203: The terminal device sends the BSR of the first standard and the BSR of the second standard to the network device.

According to the above S201 and S202, the terminal device determines the BSR of the first mode and the BSR of the second mode of the first link, and then, the terminal device sends the BSR of the first mode and the BSR of the second mode of the first link to the network device. BSR enables the network equipment to determine the amount of data to be transmitted in each LCG of each target address information in the corresponding standard according to the first information and the second information in the BSR, and allocate a reasonable amount of data to the terminal equipment on the corresponding carrier of the corresponding standard Scheduling resources.

In a possible implementation manner, the terminal device includes the BSR of the first standard in the first buffer status report media access control layer control element (BSR Media Access Control Element, BSR MAC CE) and sends it to the network device. The BSR of the second standard is included in the second BSR, MAC, CE and sent to the network device. When the network device receives the first BSR MAC CE, it obtains the BSR of the first standard from the first BSR MAC CE. When the network device receives the second BSR MAC CE, it obtains the second BSR from the second BSR MAC CE. Standard BSR.

Optionally, the first BSR MAC CE and the second BSR MAC CE include corresponding standard information. One possible way is to indicate by implicit information, such as the names of different BSR MAC CEs to indicate the standard information of the BSR MAC CE. ; Another possible way is to indicate by displaying information, such as a bit in the first BSR MAC CE to indicate the standard information of the first BSR MAC CE, and a bit in the second BSR MAC CE to indicate the second BSR MAC CE standard information. In this way, when the network device allocates scheduling resources, it can determine whether to allocate the scheduling resources of the first standard or the scheduling resources of the second standard according to the standard 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 standard and the BSR of the second standard in the same BSR MAC CE and sends to the network device; optionally, this time can indicate the standard corresponding to the BSR Information, for example, the standard information of each BSR is indicated by a bit, so that when the network device allocates scheduling resources, it can determine whether to allocate the scheduling resources of the first standard or the scheduling resources of the second standard according to the BSR standard information .

In the embodiment of the present application, the terminal device determines the BSR of the first standard of the first link. The BSR of the first standard includes at least one piece of first information. The first information includes the index of target address information, logical channel group LCG information, Information about the size of the buffer area, where the information about the buffer area size has a corresponding relationship with the index of the target address information and the LCG information; and determines the BSR of the second mode of the first link, and the BSR of the second mode includes at least one second The second information includes the index of the target address information, LCG information, and information about the size of the buffer area, where the information about the buffer area size has a corresponding relationship with the index of the target address information and the LCG information; then, the terminal device sends to the network device The BSR of the first mode and the BSR of the second mode provide the basis for subsequent resource scheduling of network equipment.

On the basis of the above-mentioned embodiment, the following combines different implementations to report the first information and the second information in the BSR buffer status, the sorting method in the BSR Media Access Control Element (BSR MAC CE) To make a detailed introduction, it should be noted that the ordering manner of the first information and the second information in the BSR MAC CE of the BSR involved in the embodiment of the present application includes but is not limited to the following methods.

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

S2001. The terminal device determines the order of at least one piece of first information in the BSR MAC CE of the BSR of the first standard according to the first preset priority rule, or determines that the at least one piece of second information is in the BSR MAC CE of the BSR of the second standard Sorting in CE.

The above S2001 is executed before the above S201.

Specifically, if the BSR of the first standard and the BSR of the second standard are included in different BSR MAC CEs, for example, the BSR 1 of the first standard is included in the BSR MAC CE 1, and the BSR 2 of the second standard is included in the BSR MAC CE. In 2, the BSR 1 of the first standard includes one or more pieces of first information, so 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, according to the first preset It is assumed that the priority rule ranks the first information included in the BSR1. The BSR 2 of the second standard includes one or more second information, so 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, according to the first preset priority rule Sort each second information included in the BSR 2.

Exemplarily, the foregoing first preset priority rule includes:

The terminal device arranges the at least one piece of first information in descending order according to the priority of the at least one piece of first information, where the priority of the first piece of information is the highest priority of the logical channel to be transmitted in the LCG associated with the LCG information included in the first piece of information Or, according to the at least one second information, arrange the at least one second information in descending order, where the priority of the second information is the highest priority of the logical channel in the LCG associated with the LCG information included in the second information.

Continuing to refer to Figure 4, suppose Figure 4 is the BSR 1 of the first standard. The BSR 1 includes 4 pieces of first information. The first information 1 includes: destination index 1, LCG 1 and buffer size 1, and first information 2. Including: destination index 1, LCG 3 and buffer size 2. The first information 3 includes destination index 2, LCG 2 and buffer size 3. The first information 4 includes destination index 2, LCG 3, and buffer size 4. The first information 1 includes the LCG 1 and the logical channels to be transmitted including the LCH 1 and LCH 2, the first information 2 includes the LCG 3 and the logical channels to be transmitted including the LCH 3, and the first information 3 includes The logical channel included in the LCG 2 with data to be transmitted is LCH 4, and the logical channel included in the LCG 3 included in the first information 4 is LCH 5 and LCH 6. Among them, the priority of LCH 1 in the LCG 1 included in the first information 1 is higher than the priority of LCH 2, therefore, the highest priority of the logical channel to be transmitted in the LCG 1 associated with the first information 1 including the LCG information is The priority of LCH 1, the priority of LCH 5 in the LCG 3 included in the first information 4 is higher than the priority of LCH 6, therefore, the first information 4 includes the highest logical channel for data transmission in the LCG associated with the LCG information The priority is the priority of LCH 5, and the highest priority of the logical channels in the LCG associated with the LCG information included in each first information, from highest to bottom, is: the priority of LCH 1 of the first information, The priority of the LCH 4 of the first message 3, the priority of the LCH 5 of the first message 4, and the priority of the LCH 3 of the first message 2 are then obtained for the first message in the BSR MAC CE of the BSR of the first standard The sorting is shown in Table 7:

Table 7, the order of the first information in the BSR MAC CE of the BSR of the first standard

第一信息1First message 1	LCG 1LCG 1	buffer size 1buffer size 1	destination index 1destination index 1
第一信息3First message 3	LCG 2LCG 2	buffer size 3buffer size 3	destination index 2destination index 2
第一信息4First message 4	LCG 3LCG 3	buffer size 4buffer size 4	destination index 2destination index 2
第一信息2First message 2	LCG 3LCG 3	buffer size 2buffer size 2	destination index 1destination index 1

In the same way, referring to the ordering manner of the first information in the BSR MAC CE of the BSR of the first standard, the ordering of the second information in the BSR MAC CE of the BSR of the second standard can be obtained, which will not be repeated here.

Optionally, the priority of the LCH in the above LCG can be based on the ProSe Per-Packet Priority (PPPP), ProSe Per-Packet Reliability (PPPR), and the fifth generation of the PC5 port. Communication system service quality identifier (PC5QoS identifier, PQI), car networking communication system service quality identifier (V2X QoS identifier, VQI), fifth-generation communication system service quality identifier (5G QoS identifier, 5QI), PC5QoS flow identifier (PC5QoS flow identity) , PC5QFI) or the specific priority associated with the LCH itself. The smaller the PPPP value, the higher the priority. The priority of PQI, VQI, 5QI or PC5QFI is the priority parameter in a group of associated QoS parameters (such as The priority level parameter in the QoS characteristics obtained by the 5QI mapping identifies the priority of the 5QI).

Optionally, if the first standard is LTE and the second standard is NR, each LCH in the LCG included in the first information indicates the priority according to the PPPP or PPPR value, and each LCH in the LCG included in the second information is based on the PQI, The priority value associated with VQI, 5QI, PC5QFI or LCH characterizes the priority.

After determining the order of the first information in the BSR MAC CE of the BSR of the first standard and the order of the second information in the BSR MAC CE of the BSR of the second standard according to the above steps, it is also necessary to determine the BSR of the BSR of the first standard The ordering of MAC CE and BSR MAC CE of BSR of the second standard may specifically include the following ordering methods:

Method 1: The BSR MAC CE of the BSR of the first standard is arranged before the BSR MAC CE of the BSR of the second standard; or the BSR MAC CE of the BSR of the first standard is arranged after the BSR MAC CE of the BSR of the second standard .

Manner 2: According to the BSR MAC CE of the BSR of the first standard, the priority of the first information with the highest priority among the at least one first information included, and the BSR MAC CE of the BSR of the second standard includes at least one second information The priority of the second information with the highest priority determines the order of the BSR MAC CE of the BSR of the first standard and the BSR MAC CE of the BSR of the second standard. The priority of the first information is related to the LCG information included in the first information. The associated LCG has the highest priority of the logical channel for data to be transmitted, and the priority of the second information is the highest priority of the logical channel for the data to be transmitted in the LCG associated with the LCG information included in the second information. For example, referring to the method involved in Table 7 above, among at least one piece of first information included in the BSR MAC CE of the BSR of the first standard, the LCG information included in each first information is associated with the logical channel for data transmission in the LCG The highest priority of each first information is used as the priority of each first information; in the same way, among the at least one second information included in the BSR MAC CE of the BSR of the second standard, the LCG information included in each second information is associated with the LCG The highest priority of the logical channel with data to be transmitted is taken as the priority of each second information. Assume that the BSR MAC CE of the BSR of the first standard includes at least one piece of first information with the highest priority among the first information 1. Assume that the BSR MAC CE of the BSR of the second standard includes at least one piece of the second information with the highest priority. The second information is the second information 3. At this time, if the priority of the first message 1 is higher than the priority of the second message 3, the BSR MAC CE of the BSR of the first standard is arranged before the BSR MAC CE of the BSR of the second standard. If the priority is higher than the priority of the first message 1, the BSR MAC CE of the BSR of the second standard is arranged before the BSR MAC CE of the BSR of the first standard. It should be noted that if the parameter used to characterize the priority of the first information 1 and the parameter used to characterize the priority of the second information 3 are different, the parameter used to characterize the priority of the first information 1 can be combined with The parameters used to characterize the priority of the second information 3 are converted into the same parameter and then compared.

In the method of the embodiment of this application, when the BSR of the first standard and the BSR of the second standard are included in different BSR MAC CEs, it is determined by the above method that at least one piece of first information is sorted in the BSR MAC CE of the BSR of the first standard And and at least one piece of second information is sorted in the BSR MAC CE of the BSR of the second standard, so that the network device can sort the first information and the second information reported by the terminal device into the first information and priority with higher priority The second information with a higher level is preferentially allocated to corresponding scheduling resources.

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

S2002: Determine the order of at least one piece of first information and at least one piece of second information in BSR MAC CE according to the second preset priority rule.

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

The above S2002 is executed before the above S202.

Specifically, if the BSR 1 of the first standard and the BSR 2 of the second standard are included in the same BSR MAC CE, that is, the BSR MAC CE includes at least one piece of first information in the BSR 1, and also includes the information in the BSR 2. At least one piece of second information. 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 sorted in the BSR MAC CE, for example, according to the second preset priority rule , It is determined that each first information and each second information are sorted in the BSR MAC CE.

Exemplarily, the foregoing second preset priority rule includes the following methods:

Manner 1: At least one piece of first information is arranged before the at least one piece of second information; or, at least one piece of first information is arranged after the at least one piece of second information.

Manner 2: At least one piece of first information is interspersed with at least one piece of second information.

For example, ranking first information with a priority higher than or equal to the first priority in at least one first information before at least one second information, and ranking at least one second information with a lower priority or equal to at least one first information Before the first message of 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 priority higher than threshold 2 in each first information can be sorted first, and then all the second information is sorted, and finally, the priority of each first information is lower than threshold 2 The first information.

For another example, the second information with 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 lower than the priority in the at least one second information Or before the second message with the second priority. Assuming that the second priority is threshold 3, the second information with priority higher than threshold 3 in each second information can be sorted first, then all the first information, and finally the second information with priority lower than threshold 3 Second information.

Optionally, the foregoing first priority and 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. Optionally, the foregoing RRC dedicated signaling , The priority of the first priority and the second priority of the configuration of 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 PPPP, PPPR, PQI, VQI, 5QI, PC5QFI, or specific priority associated with the LCH itself. Optionally, if the first standard is LTE and the second standard is NR, the priority of the first information can be characterized by the parameter PPPP or PPPR value, and the priority of the second information can be characterized by the parameters PQI, VQI, 5QI, PC5QFI or Characterization of the priority value associated with LCH.

Manner 3: At least one piece of first information and at least one piece of second information are sorted according to a uniform priority.

Specifically, if the parameter used to characterize the priority of the first information is different from the parameter used to characterize the priority of the second information, at least one parameter of the priority of each first information in the first information will be characterized, and The parameter representing the priority of each second information in the at least one second information is 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. In this way, the PPPP value used to characterize the priority of the first information can be converted into a PQI value, or use The PQI value representing the priority of the second information is converted into a PPPP value. According to the unified priority after conversion, each first information and each second information are sorted, thereby improving the accuracy of sorting.

Optionally, there is a mapping relationship between the unified priority and the priority of at least one piece of first information and the priority of at least one piece of second information. For example, the terminal device maintains the above-mentioned mapping table. Through the mapping table, the unified priority corresponding to the priority of at least one first information and the unified priority corresponding to the priority of at least one second information can be found, which is convenient for the terminal device according to each priority. The unified priority corresponding to the priority of the first information and the unified priority corresponding to the priority of each second information are used to sort the first information and the second information, thereby improving the sorting efficiency. The above mapping table may be configured according to at least one of the RRC dedicated signaling, system broadcast message, and preset configuration information sent by the network device. Optionally, the configuration of the above RRC dedicated signaling, system broadcast message, and preset configuration information The priority of the mapping table decreases sequentially.

In the method of the embodiment of this application, when the BSR of the first standard and the BSR of the second standard are included in the same BSR MAC CE, it is determined by the above method that at least one piece of first information and at least one piece of second information are ranked in the BSR MAC CE , So that the network device can preferentially allocate corresponding scheduling resources to the first information with high priority and the second information with high priority according to the order of the first information and the second information reported by the terminal device.

It should be noted that there is no sequence between S401 and S402, that is, S401 can be executed before S402, or 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 It is the carrier information of the second standard 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 standard included in the above third information indicates the carrier index. In this way, the network device first sends the third information to the terminal device, and the terminal device obtains the carrier index of the first standard from the third information, and then, The corresponding relationship between the carrier index of the first standard and the target address information is determined, and the carrier index and target address information of the first standard are included in the first information of S101 and sent to the network device. In the same way, the network device first includes the carrier information of the second standard in the fourth information and sends it to the terminal device. The carrier information of the second standard included in the fourth information indicates the carrier index. The terminal device obtains the carrier index of the second standard from the fourth information, determines the correspondence between the carrier index of the second standard and the target address information, and includes the carrier index of the second standard and the target address information in the first step of S102. The second information is sent to the network device.

The first link is a direct wireless communication link between the terminal device and other terminal devices. road. The control channel may be a Physical Sidelink Control Channel (PSCCH), and the control channel is used to transmit link control information (Sidelink Control information, SCI).

Optionally, in this step, the terminal device may send fifth information to the network device. The fifth information includes carrier index and target address information, and the carrier index has a corresponding relationship with the target address information. The carrier index included in the fifth information may be the index of the carrier of the first standard included in the third information or the index of the carrier of the second standard included in the fourth information.

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 numbering method of the carrier index of the first standard and the carrier index of the second standard will be combined with specific implementation methods. Give a detailed introduction.

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

The network device of the present application may include the third information and the fourth information in the same information unit and send it to the terminal device, and the third information includes the carrier index of at least one carrier supporting the first standard, and the fourth information includes supporting the second standard The carrier index of at least one carrier of the system. When the carrier indexes of different standards are sent in one information unit, the carrier indexes of different standards need to be numbered effectively, so that the terminal device can accurately identify the first standard from the same information unit. The carrier index and the carrier index of the second standard.

Optionally, the foregoing third information or fourth information may be in the form of a container. For example, when the Uu port is an LTE Uu port, the fourth information is in the form of a container and the third information is included in the same IE: When the Uu port is an NR Uu port, the third information is in the form of a container and the fourth information is included in the same IE.

A. In the first case, if the number of the carrier index is directly numbered, the numbering method of the carrier index includes but is not limited to the following three:

Manner 1: The number of the carrier index of the first standard included in the third information is adjacent to the number of the carrier index of the second standard included in the fourth information.

Specifically, referring to the correspondence between the carriers of the first standard and the carrier indexes shown in Table 8 above, the carrier indexes of the first standard are sequentially numbered in the third information, and the sequential numbers may be ascending numbers as shown in Table 8. It can also be in descending order.

Table 8. Correspondence between the carrier of the first standard and the carrier index

载波1Carrier 1	Index 1Index 1
载波2Carrier 2	Index 2Index 2

Carrier 3

Index 3

Refer to the correspondence between the carrier of the second standard and the carrier index shown in Table 9 above, where the carrier index of the second standard is numbered sequentially in the fourth information, and the sequence number can be an ascending number as shown in Table 9, or it can be Number in descending order.

Table 9, Correspondence between the carrier of the second standard and the carrier index

载波3Carrier 3	Index 4Index 4
载波5Carrier 5	Index 5Index 5

It can be seen from Table 8 and Table 9 that the number of the carrier index of the first standard included in the third information is adjacent to the number of the carrier index of the second standard included in the fourth information, for example, the first standard included in the third information The carrier index numbers of is 1 to 3, and the fourth information includes the numbers 4 to 5 of the carrier index of the second standard.

Table 8 and Table 9 are just examples. Optionally, the carrier index of the second system included in the fourth information may be numbered first, and then the carrier index of the first system included in the third information may be numbered, for example, The carrier indexes of the second standard included in the fourth information are numbered 1 to 2, and the carrier indexes of the first standard included in the third information are numbered 3 to 5.

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

Manner 2: The number of the carrier index of the first standard included in the third information and the number of the carrier index of the second standard included in the fourth information are sequentially numbered, and the third information includes the The difference between the smallest number of the carrier index of the first standard and the smallest number of the carrier index of the first standard included in the fourth information is equal to K, where K is a positive integer.

Continuing to refer to Table 8, the carrier index numbers of the first standard included in the third information are numbered sequentially according to the sort order of the carriers of the first standard. The order number can be ascending or descending as shown in Table 8. Numbering.

In this application, the difference between the smallest number of the carrier index of the first standard included in the third information and the smallest number of the carrier index of the second standard 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 standard included in the third information and the number of the carrier index of the second standard included in the fourth information do not overlap. For example, if the number range of the carrier index of the first standard included in the third information is 1 to 3, the above K should be a positive integer greater than or equal to 3, for example, the minimum is 3.

Exemplarily, assuming that the above K is 10, on the basis of the above Table 9, the number of the carrier index of the second standard included in the fourth information of the present application may be as shown in Table 10, where the sequence number of the carrier index of the second standard . The sequence number can be ascending or descending as shown in Table 10.

Table 10 Correspondence between the carrier of the second standard and the carrier index

载波3Carrier 3	Index 11Index 11
载波5Carrier 5	Index 12Index 12

It can be seen from Table 8 and Table 9 that the difference between the smallest number 1 of the carrier index of the first system included in the third information and the smallest number 11 of the carrier index of the second system included in the fourth information is equal to a positive integer K= 10.

Optionally, the terminal device can configure the above K in different ways, for example, the terminal device configures it through at least one of radio resource control RRC dedicated signaling, system broadcast messages, and preset configuration information sent by the network device.

Optionally, the foregoing RRC dedicated signaling, system broadcast message, and preset configuration information have configuration priorities. For example, the configuration priorities of RRC dedicated signaling, system broadcast messages, and preset configuration information are sequentially reduced. In this way, when the terminal device receives RRC dedicated signaling, system broadcast message, and preset configuration information at the same time, it can determine the value of K according to the configuration priority among the three, for example, determine the value of K according to RRC dedicated signaling. value.

Manner 3: The number of the carrier index of the first standard included in the third information and the number of the carrier index of the second standard included in the fourth information are sequentially numbered, and the third information includes The smallest number of the carrier index of the first standard is equal to the smallest number of the carrier index of the second standard included in the fourth information, and the DCI or the fifth information or the sixth information further includes the carrier index The corresponding standard information.

Continuing to refer to Table 8, the third information includes the serial number of the carrier index of the first standard.

At the same time, the fourth information includes the serial number of the carrier index of the second standard, and the smallest number of the carrier index of the first standard included in the third information is equal to the smallest number of the carrier index of the second standard included in the fourth information.

Exemplarily, the correspondence between the carrier of the second standard and the carrier index included in the fourth information is shown in Table 11, where the number of the carrier index of the second standard included in the fourth information is numbered sequentially in the fourth information, and The smallest number of the carrier index of the second standard included in the fourth information and the smallest number of the carrier index of the first standard included in the third information are equal, for example, both are 1.

Table 11. Correspondence between the carrier of the second standard and the carrier index

载波3Carrier 3	Index 1Index 1
载波5Carrier 5	Index 2Index 2

It can be seen from Table 8 and Table 11 that the carrier index numbers of the first system included in the third information and the carrier index numbers of the second system included in the fourth information both start from a certain preset value (for example, 1), and each Sequence label.

In this manner, the number of the carrier index of the first standard included in the third information overlaps with the number of the carrier index of the second standard included in the fourth information. For example, index 1 corresponds to both carrier 1 supporting the first standard and Support carrier 3 of the second standard. In this way, when the network device sends the aforementioned third information and fourth information to the terminal device, the terminal device cannot determine which carrier the index1 corresponds to.

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

Optionally, in order to save downlink resources, the system information corresponding to the above-mentioned carrier index may be represented by one 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 of the carrier index includes but is not limited to the following:

Manner 1: The number range of the carrier index of the first standard included in the third information is adjacent to the number range of the carrier index of the second standard included in the fourth information.

Exemplarily, it is assumed that the number range of the carrier index of the first standard included in the third information is 1 to 50, and the number range of the carrier index of the second standard included in the fourth information is 51 to 100.
