Hereinafter, in conjunction with specific embodiments, the method for determining the corresponding priority level of the priority level in the first priority classification in the second priority classification is described.

Embodiment 1: The first device combines the number N of priority levels included in the first priority classification and the number of priority levels included in the second priority classification according to the first priority level The quantitative relationship between the numbers M determines the corresponding priority level of the first priority level in the second priority class.

Embodiment 1-1: If the N is greater than the M, the result obtained by dividing the first priority level by K and rounding is determined as the first priority level in the second priority classification The corresponding priority level of, where the K is the ratio of the N to the M.

As an embodiment, if the first priority classification includes priority levels 1 to N, and the second priority classification includes priority levels 1 to M, the priority levels of the priority levels 1 to N may be The result obtained by dividing the rank by K and rounding up is determined as the corresponding priority rank in the second priority classification.

For example, if the N is 16, the priority levels are 1-16, the M is 8, and the priority levels are 1 to 8, then the first priority level X in the first priority classification is The corresponding priority level in the second priority classification is the result of X/2 rounded up.

For another example, if the N is 16, the priority levels are 1-16, the M is 2, and the priority levels are 1 to 2, then the first priority level X in the first priority classification The corresponding priority level in the second priority classification is the result of rounding up X/8.

As another embodiment, if the first priority classification includes priority levels 0 to N-1 and the second priority classification includes priority levels 0 to M-1, the priority levels 0 to The result obtained by dividing the priority level in N-1 by K and rounding down is determined as the corresponding priority level in the second priority classification.

For example, if the N is 16, the priority levels are 0-15, the M is 8, and the priority levels are 0-7, then the first priority level X in the first priority classification is The corresponding priority level in the second priority classification is the result of X/2 rounded down.

For another example, if the N is 16, the priority levels are 0-15, the M is 2, and the priority levels are 0-1, then the first priority level X in the first priority classification The corresponding priority level in the second priority classification is the result of rounding down X/8.

Embodiment 1-2: If the N is less than the M, the result obtained by multiplying the first priority level by P and subtracting Q is determined that the first priority level is in the second priority level The corresponding priority level in the classification, where P is the ratio of the M to the N, and the Q is an integer less than P.

For example, if the N is 8, the priority levels are 1-8, the M is 16, and the priority levels are 1-16, then the first priority level X in the first priority classification is The corresponding priority level in the second priority classification is 2X or 2X-1;

For another example, if the N is 2, the priority levels are 1-2, the M is 16, and the priority levels are 1-16, then the first priority level X in the first priority classification is The corresponding priority level in the second priority classification is 8X-Q, where the Q is an integer less than 8, for example, 0 or 7, etc.

In some embodiments, if the first priority classification includes priority levels 0 to N-1, and the second priority classification includes priority levels 0 to M-1, in this embodiment 1-2, The first device may determine that the result obtained by adding one to the first priority level, multiplying it by P, and then subtracting Q as the corresponding priority of the first priority level in the second priority classification Grade, where P is K is the ratio of M to N, and Q is an integer smaller than P.

For example, if the N is 8, the priority levels are 0-7, the M is 16, and the priority levels are 0-15, then the first priority level X in the first priority classification is The corresponding priority level in the second priority classification is 2(X+1) or 2(X+1)-1;

For another example, if the N is 2, the priority levels are 0-1, the M is 16, and the priority levels are 0-15, then the first priority level X in the first priority classification is The corresponding priority level in the second priority classification is 8(X+1) or 8(X+1)-1.

It should be understood that in the embodiment of the present application, the N, M are only used to indicate the number of priority levels, and the embodiment of the present application does not specifically limit the way of expressing the priority levels in the priority classification. For example, the priority levels can be 1 to N to represent N priority levels, or 0 to N-1 can be used to represent the N priority levels, or other methods can be used to represent the N priority levels. The embodiments of this application do not limit this.

It should be noted that the method of determining the corresponding priority level according to the relationship between the number of priority levels included in the two priority classifications in the first embodiment is mainly based on this representation from 1 to N, when the priority classification When the priority level in is used in other ways, you can first convert the value of the priority level into the priority level order in the priority classification, the priority level order can be 1 to N, and then according to the priority level The calculation can be performed in sequence in combination with the calculation method in Embodiment 1. If the M priority levels of the second priority classification are not expressed in the form of 1 to M, after obtaining the corresponding priority level according to the calculation method in Embodiment 1, the corresponding priority level can be understood It is the priority level sequence, and the priority level of the priority level sequence in the second priority classification is further determined as the target corresponding priority level of the first priority level.

For example, the first priority classification includes 4 priority levels, namely 1, 3, 5, and 7, the order of priority levels from high to low is 1, 3, 5, 7, and the second priority classification includes 8 priority levels, respectively 0-7, when determining the corresponding priority level of priority level 3 in the first priority classification in the second priority classification, you can first convert the priority level 3 to priority The priority level order is 2, and then according to embodiment 1-2, the corresponding priority level is determined to be 3 or 4. Since the second priority classification starts from 0, the corresponding priority level 3 or 4 can be understood as priority The order of levels 3 and 4 can further determine the third and fourth highest priority levels in the second priority category, that is, priority level 2 or 3 is the corresponding priority level of priority level 3.

It should be understood that, in the embodiment of the present application, the order of the first priority level in the N priority levels is the same as the order of the corresponding priority level in the N corresponding priority levels, where The N corresponding priority levels are corresponding priority levels of the N priority levels in the second priority classification. That is, the priority order of the N priority levels in the first priority classification is the same as the priority order of the N corresponding priority levels.

For example, if the first priority classification includes priority level 1 and priority level 2, and priority level 1 is higher than priority level 2, the priority level 1 and priority level 2 are corresponding to the priority in the second priority level The levels are respectively corresponding priority level 1 and corresponding priority level 2, where the priority level corresponding to priority level 1 is higher than or equal to the corresponding priority level 2.

Embodiment 2: The first device may determine the corresponding priority level of the first priority level in the second priority level according to the first priority level in combination with the first mapping relationship, and The first mapping relationship is the corresponding relationship between the N priority levels and the M priority levels.

Optionally, in some embodiments, if N is greater than M, in the first mapping relationship, one priority level in the second priority category may correspond to at least one priority level in the first priority category grade.

Optionally, in other embodiments, if M is greater than N, in the first mapping relationship, one priority level in the first priority classification may correspond to at least one priority in the second priority classification Level rating.

Optionally, the first mapping relationship may be configured by a network device, or may also be configured by another terminal, or may also be predefined.

Embodiment 3: The first device determines the corresponding priority level of the first priority level in the second priority classification according to the QoS upper-layer indicator PQI associated with the radio bearer of the first link.

In some embodiments, the priority level indicated by the PQI is the same as the range of the priority level included in the second priority classification. In this case, it can be based on the radio bearer associated with the first link. The QoS upper layer indicates the PQI, and determines the corresponding priority level of the first priority level in the second priority class. For example, the priority level indicated by the PQI may be set as the first priority level in the The corresponding priority level in the second priority classification.

Embodiment 4: Determine the corresponding priority level of the first priority level in the second priority classification according to the instruction information of the second device, and the instruction information is used to indicate that the first priority level is in the The corresponding priority level in the second priority category.

In some embodiments, the second device may be a network device, and the network device may configure the first device to correspond to the first priority level in the second priority classification through the instruction information Priority level, for example, the network device may authorize the first device to configure the corresponding priority information through the resources of the first link, and the indication information may be included in the resources of the first link In the authorized configuration information, or, the network device may also configure the first device with the corresponding priority level of the first priority level in the second priority category through other downlink information or downlink signaling. This application The embodiment does not limit this.

In other embodiments, the second device may be a terminal device, denoted as a second terminal, and the second terminal may configure the first device with instruction information that the first priority level is in the second The corresponding priority level in the priority classification. For example, the second terminal may authorize the first device to configure the corresponding priority information through the resources of the first link, and the indication information may be included in all In the configuration information of the resource authorization of the first link, or, the second terminal may also configure the first device with other sideline information or sideline signaling to configure the first priority level in the second The corresponding priority level in the priority classification is not limited in the embodiment of the present application.

It should be understood that the above embodiments are described by taking the priority level of one link corresponding to the priority classification of another link as an example. In other embodiments, the priority of the two links may also be The levels all correspond to the third priority category. For example, it is possible to determine the corresponding priority of the first priority level of the first link in the third priority category, and determine that the second priority level of the second link is in the The corresponding priorities in the third priority classification are further compared with the corresponding priorities of the first priority class and the second priority class in the third priority classification to determine the first link and the The priority transmission link in the second link.

For example, the first priority classification includes 4 priority levels, the second priority classification includes 6 priority levels, and the priority of the first priority classification and the second priority classification may be The class level corresponds to the third priority class. The third priority class can include A priority classes, where A can be a common multiple of the number of priority classes included in the first priority class and the second priority class. For example, A is 12, where the corresponding priority levels of the first priority classification and the second priority classification in the third priority classification can be determined with reference to the related description of Embodiment 1. , I won’t repeat it here. Suppose that the priority level X in the first priority classification corresponds to the priority level 3X in the third priority classification, and the priority level Y in the second priority classification corresponds to the third priority classification If the priority level 2Y in the middle, the first device can compare the corresponding priority levels 3X and 2Y to determine the priority of the first link and the second link.

Therefore, in the embodiment of the present application, the first device can map the priority levels of the two links to a unified priority classification when the link communication of two different networks conflicts, which can be further based on the unified priority classification. Priority classification for priority comparison is beneficial to improve the accuracy of priority judgment, thereby ensuring the priority transmission of links with high priority.
