Technical Field

The present application relates to the field of wireless communications, and in particular, to the technical field of controlling user equipment to perform duplicate transmission.

In addition, in order to make the embodiments of the present application easier to understand, the main concepts referred to in the present specification are further explained as follows.

Reliability requirements of the target service: proSe Per-packet reliability, PPPR, i.e. near field communication single packet reliability requirements, different PPPR values represent different reliability requirements.

First configuration parameters: also referred to as "first configuration", in this embodiment of the present application, the first configuration parameter includes a correspondence between a first index, such as a reliability requirement of the target service, a channel busy rate, and whether to copy and transmit data of the target service, that is, whether to copy and transmit the data of the target service may be determined according to the first configuration parameter and the first index.

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The technical scheme of the application can be applied to various terminal-to-terminal communication systems, such as the Internet of vehicles and the like.

The scene architecture applied in the embodiments of the present application is described below.

As mentioned above, the internet of vehicles technology (V2X) was standardized in 3GPP Rel-14, defining two transmission modes: mode 3 and mode 4.

Specifically, for mode 3, as shown in fig. 1, the transmission resources of the vehicle-mounted terminal are allocated by the base station, and the vehicle-mounted terminal transmits data on the side link according to the resources allocated by the base station; the base station may allocate resources for single transmission to the terminal, or may allocate resources for semi-static transmission to the terminal.

Specifically, for mode 4, as shown in fig. 2, the vehicle terminal adopts a transmission method of interception (transmission) +reservation (reservation). The vehicle-mounted terminal acquires an available transmission resource set in a resource pool in a interception mode, and the terminal randomly selects one resource from the set to transmit data.

Because the service in the internet of vehicles system has a periodic characteristic, the terminal generally adopts a semi-static transmission mode, that is, after the terminal selects one transmission resource, the resource is continuously used in a plurality of transmission periods, so that the probability of resource reselection and resource conflict is reduced.

The terminal can carry the information of the reserved secondary transmission resources in the control information of the current transmission, so that other terminals can judge whether the resources are reserved and used by the user or not by detecting the control information of the user, and the purpose of reducing resource conflict is achieved.

In addition, the embodiments of the present application apply to carrier aggregation.

Specifically, for carrier aggregation (carrier aggregation, CA), the scheme supporting data duplicate transmission (data duplicate) utilizes the duplicate data function of PDCP, so that duplicate PDCP PDUs are respectively transmitted to two RLC entities (two different logical channels), and finally the duplicate PDCP PDUs can be transmitted on different physical layer aggregated carriers, thereby achieving frequency diversity gain to improve data transmission reliability. A specific protocol structure is shown in fig. 3.

The first embodiment of the invention relates to a method for controlling user equipment to perform copy transmission in a communication system. Fig. 4 is a flow chart of a method of controlling user equipment for duplicate transmission in the communication system. The method comprises the following steps:

in step 401, the user equipment obtains a first indicator including a reliability requirement of the target service and a first configuration, where the first configuration includes a first correspondence between the reliability requirement of the target service and whether to perform copy transmission.

In step 402, it is determined whether the user equipment performs copy transmission on the data of the target service according to the acquired first index and the first configuration.

The manner in which the target business reliability requirements are represented and configured can vary, to name a few.

Example 1: and presetting a reliability requirement threshold (namely a first threshold), and when the reliability requirement of the target service is higher than or equal to the threshold (namely an index representing the reliability requirement of the target service is higher than or equal to the first threshold), carrying out data copying and transmission by the user equipment. Or if the first index is lower than or equal to the first threshold, determining that the user equipment performs copy transmission on the data of the target service. The indexes representing the target service reliability requirement can be bit error rate, block error rate, correct transmission probability and the like.

Example 2: the first configuration may be set in connection with a channel busy rate Channel Busy Ratio (CBR) of the communication system.

In one embodiment, the first configuration may be changed when the CBR changes. For example, the current configuration of a certain user equipment is configured to perform data copy transmission, and when CBR changes, the network side changes the current configuration of the user equipment to not perform data copy transmission.

In one embodiment, a table (i.e., a second correspondence is configured that includes a correspondence of channel busy rate versus whether duplicate transmissions are made). In step 402, the ue queries the second correspondence according to the channel busy rate value measured by the ue, and determines whether to copy and transmit the data of the target service according to the query result.

In one embodiment, a threshold (i.e., a second threshold) is configured, and in step 402, if the channel busy rate value measured by the ue itself is lower than or equal to the second threshold, the data of the target service is duplicated and transmitted.

The carrier and CBR values in some embodiments of embodiment 2 are specifically described below.

Specifically, in some implementations of the present application, the CBR value includes a CBR value of at least one carrier.

Further, in step 402, the maximum or minimum CRB value of the at least one carrier is compared with a second threshold.

The significance of this is that when a carrier comprises a plurality of resource pools, each having a corresponding CBR, it is necessary to determine which resource pool of which carrier is specifically used corresponds to the channel busy rate and to compare with a second threshold, in which case the principle of specifically choosing the channel resource rate, in other words, the specific value of the CBR value for comparison with the second threshold, is required to be defined.

That is, in some implementations of the present application, there are multiple resource pools in one carrier, each corresponding to one CBR value, and when comparing the CBR value with the second threshold, either the maximum value of the multiple CBR values corresponding to the multiple resource pools may be compared with the second threshold or the minimum value thereof may be compared with the second threshold.

In addition, in one embodiment, the at least one carrier is at least one carrier corresponding to the target service. In this case, the CBR value comes from the carrier corresponding to the target traffic. Alternatively, the at least one carrier may be at least one carrier corresponding to a logical channel carrying the duplicated data. In this case, the CBR value comes from the carrier corresponding to the logical channel carrying the duplicate data.

When the target service corresponds to a plurality of carriers or the logical channel carrying the copy data corresponds to a plurality of carriers, the CBR value is the maximum value or the minimum value of CBR in the plurality of carriers.

In general, in some embodiments of the present application, when determining whether to copy data of a target service based on a CBR value, first, the CRB value may be from a carrier corresponding to the target service or a carrier corresponding to a logical channel carrying the copied data. Second, the maximum value of the CBR values corresponding to the plurality of resource pools may be compared with the second threshold, or the minimum value thereof may be compared with the second threshold.

The method has the advantages that the copying and transmitting modes of the data of the target service are more flexible, the system resources are utilized more fully and reasonably, and the data of the target service meeting the reliability requirement is better ensured to be copied and transmitted as timely as possible.

Example 3: the first configuration set according to different reliability requirements may be different according to the priority PPPP (prose per packet priority) of the target traffic.

In one embodiment, a table (i.e., a third correspondence relationship, including a correspondence relationship between a channel busy rate and whether to perform copy transmission) is configured, in step 402, the ue queries the third correspondence relationship according to the priority of the target service measured by the ue, and determines whether to perform copy transmission on the data of the target service according to the query result.

In one embodiment, a threshold (i.e., a third threshold) is configured, and in step 402, if the priority value of the target service measured by the ue itself is lower than or equal to the third threshold, the data of the target service is duplicated and transmitted.

In one embodiment, the configuration includes a set, and in step 402, if the priority value of the target service measured by the ue itself belongs to the set, the data of the target service is duplicated and transmitted.

In one embodiment, a mapping relationship between PPPP and carrier is configured, and in step 402, if the ue determines that the priority value of the target service is mapped to more than one carrier according to the priority value and the mapping relationship of the target service measured by the ue, the data of the target service is duplicated and transmitted. In one embodiment, the user equipment determines a carrier wave capable of copying and transmitting the data of the target service according to the priority value and the mapping relation of the target service.

When the configuration may be different according to the priority PPPP of the target service, the mapping relationship between the logical channel and the carrier of the duplicate data may be further configured.

In one embodiment, for different PPPPs, the mapping relationship of the original data and the duplicate data with the carrier is configured, e.g., for PPPP1, the original data and the duplicate data are placed on carriers a and B, respectively.

In one embodiment, for different PPPPs, the mapping relationship between the logical channels and the carriers is configured separately, for example, for PPPP1, mapped onto logical channels I and II, and I and II are placed onto carriers a and B, respectively, to configure the mapping relationship between the logical channels and the carriers that duplicate the data.

Example 4: determining whether to copy the data of the target service and determining whether to transmit the copied copy of the data of the target service according to the reliability requirement and the channel busy rate, respectively.

Specifically, in embodiment 4, the first correspondence relationship includes: a correspondence between the reliability requirement and whether to perform the copy processing in the copy transmission;

accordingly, whether the target business data is copied or not is determined according to the first index and the first corresponding relation. Specifically, the first correspondence includes a fourth threshold, and if the reliability requirement is greater than or equal to the fourth threshold, it is determined that the user equipment performs copy processing on the data of the target service.

Optionally, in some embodiments of the present application, it may also be configured to: and if the reliability requirement is lower than or equal to the fourth threshold, determining that the user equipment performs copy processing on the data of the target service.

The configuration parameters of the reliability requirements can be flexibly set because, although the reliability requirements can currently have 8 levels, denoted by 1-8, where 8 denotes the highest reliability requirement. However, embodiments of the present application are not limited to this case, and in some embodiments, for example, there may be more levels, or the highest reliability requirement is denoted by 1, and so on. Therefore, in this case, the specific configuration or configuration parameters are not limited to the above-described specific embodiments.

In addition, the first indicator further includes a channel busy rate of the communication system;

accordingly, the first configuration further comprises: a fourth correspondence between channel busy rate and whether or not transmission processing in duplicate transmission is performed. In other words, whether to transmit a copy of the target traffic data that has been copied is determined according to the channel busy rate in the first index and the fourth correspondence.

Specifically, the fourth correspondence includes a fifth threshold, and if the channel busy rate of the user equipment is lower than or equal to the fifth threshold, it is determined to perform transmission processing on the copy of the target service data that has been copied.

Specifically, referring to fig. 5, the following steps are included in example 4:

step 501: and acquiring a first index and first configuration information.

Specifically, the first index includes both the reliability requirement and the channel busy rate.

Correspondingly, the first configuration information comprises a first corresponding relation and a fourth corresponding relation.

Wherein the first correspondence relationship includes: the correspondence between the reliability requirement and whether or not to perform the copy processing in the copy transmission. Specifically, the first correspondence includes a fourth threshold, and according to the configuration of embodiment 4, if the reliability requirement is greater than, or equal to, the fourth threshold, it is determined that the user equipment performs the copy processing on the data of the target service.

Wherein the fourth correspondence relationship includes: correspondence between channel busy rate and whether or not transmission processing in duplicate transmission is performed. Specifically, the fourth correspondence includes a fifth threshold, and according to the configuration of embodiment 4, if the channel busy rate of the user equipment is lower than or equal to the fifth threshold, it is determined to perform transmission processing on the copy of the target service data that has been copied.

Step 502: and determining whether to perform the copying processing of the target service data according to the reliability requirement in the first index and the first corresponding relation.

Specifically, the first correspondence includes a fourth threshold, if the reliability requirement is greater than or equal to the fourth threshold, it is determined that the user equipment performs the copy processing on the data of the target service, and step 503 is executed, otherwise, the flow ends.

Step 503: and the user equipment performs copying processing on the data of the target service.

Step 504: and determining whether to transmit the copied target business data copy or not according to the channel busy rate in the first index and the fourth corresponding relation.

Specifically, the fourth correspondence includes a fifth threshold, if the channel busy rate of the ue is lower than or equal to the fifth threshold, it is determined that the copy of the target service data that has been copied is transmitted, and step 505 is executed, otherwise, the process ends.

Step 505: and transmitting the copied target business data.

In embodiment 4, the characteristic that the real-time change of the channel busy rate is frequent and the reliability requirement of the target service is a relatively static value is considered, in this case, if the determination and copying of the data of the target service is restarted directly under the condition that the channel busy rate meets the threshold requirement, it is possible that the channel busy rate has changed before the copying and transmission of the data of the target service is completed, and it is possible that the copied copy is no longer suitable for transmission. Therefore, the innovation in embodiment 4 proposes an improved way to determine whether to copy according to the reliability requirement, and if the reliability requirement is met, directly copy; in addition, whether the copied copy is suitable for being transmitted currently is determined according to the channel busy rate, if the channel busy rate requirement is met, the copy is directly transmitted, if the current channel is busy, the copied copy can be buffered first, and when the channel busy rate meets the requirement again, the copy is transmitted.

The advantage of this is that: the method ensures that the copying and transmitting modes of the data of the target service are more flexible, fully and reasonably utilizes the system resources, and better ensures that the data of the target service meeting the reliability requirement is copied and transmitted as timely as possible.

Example 5: determining whether to copy the data of the target service according to the reliability requirement, determining whether to reselect the carrier carrying the copied data of the target service according to the channel busy rate, and transmitting the copy of the target service on the determined carrier.

Specifically, in embodiment 5, the first correspondence relationship includes: a correspondence between the reliability requirement and whether to perform the copy processing in the copy transmission;

It is noted above that there may be other levels or representations of the level of reliability requirements, in which case the specific configuration or configuration parameters are not limited to the specific embodiments, and are not described here.

accordingly, the first configuration further comprises: a fifth correspondence relationship between the channel busy rate and whether or not transmission processing in duplicate transmission is performed. And determining whether to reselect the carrier wave carrying the duplicated copies of the target service data according to the channel busy rate in the first index and the fifth corresponding relation, and transmitting the copies of the target service data on the determined carrier wave.

Specifically, the fifth correspondence includes a sixth threshold, and if the channel busy rate of the ue is higher than or equal to the sixth threshold, it is determined to reselect a carrier carrying the duplicate of the replicated target service data, and transmit the duplicate of the replicated target service data on the reselected carrier.

Specifically, referring to fig. 7, the following steps are included in example 5:

step 701: and acquiring a first index and first configuration information.

Correspondingly, the first configuration information comprises a first corresponding relation and a fifth corresponding relation.

Wherein the first correspondence relationship includes: the correspondence between the reliability requirement and whether or not to perform the copy processing in the copy transmission. Specifically, the first correspondence includes a fourth threshold, and according to the configuration of embodiment 5, if the reliability requirement is greater than, or equal to, the fourth threshold, it is determined that the user equipment performs the copy processing on the data of the target service.

Wherein the fifth correspondence relationship includes: correspondence between channel busy rate and whether or not transmission processing in duplicate transmission is performed. Specifically, the fifth correspondence includes a sixth threshold, and according to the configuration of embodiment 5, if the channel busy rate of the user equipment is higher than or equal to the sixth threshold, it is determined to reselect a carrier carrying the duplicate of the replicated target traffic data, and transmit the duplicate of the replicated target traffic data on the reselected carrier.

Step 702: and determining whether to perform the copying processing of the target service data according to the reliability requirement in the first index and the first corresponding relation.

Specifically, the first correspondence includes a fourth threshold, if the reliability requirement is greater than or equal to the fourth threshold, it is determined that the user equipment performs the copy processing on the data of the target service, and step 703 is executed, otherwise, the flow ends.

Step 703: and the user equipment performs copying processing on the data of the target service.

Step 704: and determining whether to reselect the carrier carrying the duplicated copies of the target service data according to the channel busy rate in the first index and the fifth corresponding relation.

Specifically, the fifth correspondence includes a sixth threshold, if the channel busy rate of the user equipment is higher than or equal to the sixth threshold, it is determined to reselect the carrier carrying the duplicate of the replicated target service data, and step 706 is performed, otherwise step 705 is performed.

Step 705: and transmitting the copied target service data copy on the original carrier.

Step 706: and carrying out carrier reselection on the carrier carrying the copied target service data copy.

Specifically, when carrier reselection is performed, a carrier with the lowest channel busy rate may be selected from the first carrier set corresponding to the current target service data, and the duplicate copy of the copied target service data is transmitted. And if the K carriers are needed for copying and transmitting the data, selecting the carrier with the lowest busy rate of the K channels from the first carrier set. The low channel busy rate indicates that the occupancy rate of transmission resources on the carrier is low, the channel is not congested, and the interference of the copy of the target service data transmitted on the carrier is smaller, so that better transmission performance can be obtained. There are many other ways of reselection of the carrier, such as priority, etc., and are not described in detail herein.

Step 707: and transmitting the copied target service data copy through the reselected carrier.

In embodiment 5, it is considered that this carrier resource is indicated to be very congested when the channel busy rate is above a predetermined threshold, e.g. the sixth threshold in the above embodiment. In this case, even if a copy of the duplicated target service data is transmitted on this carrier, a large transmission collision may result. In view of this situation, the inventor of the present application proposes that carrier reselection can be performed based on actual situations, and that a carrier that is not congested (i.e., a carrier with a low channel busy rate) is selected for more efficient and guaranteed data transmission.

The 5 embodiments are described above, but the present application is not limited to these 5 embodiments. And these 5 embodiments can be implemented independently, or the various setting conditions in the 5 embodiments can be combined in any way to embody the reliability requirement. In one embodiment, one or more combination conditions of bit error rate, CBR and PPPP may be included in the setting, and when a certain combination condition is met, the data of the target service is (or is not) duplicated for transmission. In one embodiment, the reliability requirement is a specific combination of configuration of CBR and PPPP, and when the reliability requirement of the combination is met, the data of the target service is duplicated for transmission, where the specific combination may be set according to actual needs, e.g. CBR is lower than or equal to a threshold and PPPP is lower than or equal to another threshold, CBR is lower than or equal to a threshold and PPPP is mapped to more than one carrier, CBR is in a predetermined range and PPPP belongs to a predetermined set, etc.

The second embodiment of the invention relates to equipment for controlling user equipment to perform copy transmission in a communication system. The apparatus includes:

the acquisition unit is used for acquiring a first index containing the reliability requirement of the target service and a first configuration, wherein the first configuration contains a first corresponding relation between the reliability requirement of the target service and whether copy transmission is performed or not. In one embodiment, the configuration may be stored in a memory of the user device and the control unit may be a processor or logic control circuit.

And the control unit is used for determining whether the user equipment copies and transmits the data of the target service according to the first index and the first configuration.

Example 6: a reliability requirement threshold (namely a first threshold) is preset in the first configuration, the control unit judges, and when the reliability requirement of the target service is higher than or equal to the threshold (namely an index representing the reliability requirement of the target service is higher than or equal to the first threshold), data copying and transmission are carried out; and when the reliability requirement of the target service is lower than or equal to the threshold (namely, the index representing the reliability requirement of the target service is higher than or equal to the first threshold), the data replication transmission is not performed. The indexes representing the target service reliability requirement can be bit error rate, block error rate, correct transmission probability and the like.

Example 7: the first configuration may incorporate CBR settings of the system.

In one embodiment, the configuration may be changed when the CBR changes. For example, the current configuration of a certain user equipment is not subjected to data copying transmission, and when the CBR is changed, the network side changes the current configuration of the user equipment to be subjected to data copying transmission.

In one embodiment, a table (i.e., a second correspondence is configured that includes a correspondence of channel busy rate versus whether duplicate transmissions are made). And the control unit queries a second corresponding relation according to the channel busy rate value measured by the user equipment, and determines whether to copy and transmit the data of the target service according to the query result.

In one embodiment, a threshold (i.e. a second threshold) is configured, and the control unit determines that if the channel busy rate value measured by the user equipment is lower than or equal to the second threshold, the data of the target service is duplicated and transmitted.

The carrier and CBR values in some embodiments of embodiment 7 are specifically described below.

Further, the control unit compares the CRB value of the at least one carrier with a second threshold at a maximum or minimum value.

The significance of this is that when a carrier comprises a plurality of resource pools, each having a corresponding CBR, the control unit needs to determine which resource pool of which carrier is specifically used corresponds to the channel busy rate compared to the second threshold, in which case the principle of specifically choosing the channel resource rate, in other words, the specific value of the CBR value for comparison with the second threshold, needs to be defined.

In other words, in some implementations of the present application, there are multiple resource pools in one carrier, each corresponding to one CBR value, and the control unit may use a maximum value of the CBR values corresponding to the multiple resource pools to compare with the second threshold, or use a minimum value of the CBR values to compare with the second threshold when comparing the CBR values with the second threshold.

In addition, in one embodiment, the at least one carrier is at least one carrier corresponding to the target service. In this case, the CBR value comes from the carrier corresponding to the target traffic.

Alternatively, the at least one carrier may be at least one carrier corresponding to a logical channel carrying the duplicated data. In this case, the CBR value comes from the carrier corresponding to the logical channel carrying the duplicate data.

In general, in some embodiments of the present application, when the control unit determines whether to copy and transmit the data of the target service based on the CBR value, first, the CRB value may be from a carrier corresponding to the target service or from a carrier corresponding to a logical channel carrying the copied data. Second, the control unit may compare the maximum value of the CBR values corresponding to the resource pools with the second threshold, or may compare the minimum value of the CBR values with the second threshold. The method has the advantages that the copying and transmitting modes of the data of the target service are more flexible, the system resources are utilized more fully and reasonably, and the data of the target service meeting the reliability requirement is better ensured to be copied and transmitted as timely as possible.

Example 8: the first configuration set according to different reliability requirements may be different according to different priorities PPPP of the target service.

In one embodiment, a table (i.e., a third corresponding relationship, which includes a corresponding relationship between the priority of the target service and whether to perform copy transmission) is configured, and the control unit queries the third corresponding relationship according to the priority of the target service measured by the user equipment, and determines whether to perform copy transmission on the data of the target service according to the query result.

In one embodiment, a threshold (i.e. a third threshold) is configured, and the control unit determines that if the priority value of the target service measured by the user equipment is lower than or equal to the third threshold, the data of the target service is duplicated and transmitted.

In one embodiment, the configuration includes a set, and the control unit determines that if the priority value of the target service measured by the user equipment itself belongs to the set, the data of the target service is duplicated and transmitted.

In one embodiment, a mapping relationship between PPPP and carrier is configured, and the control unit determines that if the user equipment determines that the priority value of the target service is mapped to more than one carrier according to the priority value and the mapping relationship of the target service measured by the user equipment, the data of the target service is duplicated and transmitted. In one embodiment, the user equipment determines a carrier that can copy and transmit data of the target service according to the priority value of the target service and the mapping relationship.

In one embodiment, the apparatus may further include a mapping relationship configuration unit configured to configure a mapping relationship between the logical channel and the carrier of the duplicate data. The mapping relation configuration unit has a plurality of configuration methods, for example, for the priorities of different target services, the mapping relation between the original data and the copy data and the carrier is configured; for another example, for different priorities of the target services, mapping relationships between the logical channels and the carriers are respectively configured.

Example 9: determining whether to copy the data of the target service and determining whether to transmit the copied copy of the data of the target service according to the reliability requirement and the channel busy rate, respectively.

Specifically, in embodiment 9, the first index includes a reliability requirement, and a channel busy rate. The first configuration includes a first correspondence and a fourth correspondence.

Wherein the first correspondence relationship includes: a correspondence between the reliability requirement and whether to perform the copy processing in the copy transmission; specifically, the first correspondence includes a fourth threshold, and if the reliability requirement is greater than or equal to the fourth threshold, it is determined that the user equipment performs copy processing on the data of the target service.

Wherein the fourth correspondence relationship includes: the corresponding relation between the channel busy rate and whether to perform the transmission processing in the duplication transmission; specifically, the fourth correspondence includes a fifth threshold, and if the reliability requirement is greater than or equal to the fourth threshold, it is determined that the user equipment performs copy processing on the data of the target service.

And the control unit is further used for determining whether to perform the copying processing of the target service data according to the reliability requirement in the first index and the first corresponding relation. Specifically, if the reliability requirement is greater than or equal to the fourth threshold, determining that the user equipment performs copy processing on the data of the target service.

Optionally, the control unit is further configured to determine whether to perform transmission processing on the copy of the target service data that has been copied according to the channel busy rate in the first index and the fourth correspondence. Specifically, if the channel busy rate of the user equipment is lower than or equal to a fifth threshold, it is determined to transmit a copy of the target traffic data that has been copied.

In embodiment 9, too, the characteristic that the real-time change of the channel busy rate is frequent and the reliability requirement of the target service is a relatively static value is considered, in this case, if the determination and duplication of the data of the target service is restarted directly in the case that the channel busy rate reaches the threshold requirement, it is possible that the channel busy rate has changed before the duplication and transmission of the data of the target service is not completed yet, and it is possible that the duplicated copy is no longer suitable for transmission. Therefore, in embodiment 8, whether to copy is determined according to the reliability requirement, and if the reliability requirement is satisfied, the copy is directly performed; in addition, whether the copied copy is suitable for being transmitted currently is determined according to the channel busy rate, if the channel busy rate requirement is met, the copy is directly transmitted, if the current channel is busy, the copied copy can be buffered first, and when the channel busy rate meets the requirement again, the copy is transmitted.

Example 10: determining whether to copy the data of the target service according to the reliability requirement, determining whether to reselect the carrier wave carrying the copied data of the target service according to the channel busy rate, and transmitting the copied data of the target service on the determined carrier wave.

Specifically, in embodiment 10, the first indicator includes a reliability requirement, and a channel busy rate. The first configuration includes a first correspondence and a fifth correspondence.

And if the channel busy rate of the user equipment is higher than or equal to the sixth threshold, determining to reselect the carrier carrying the copied copy of the target service data, and transmitting the copied copy of the target service data on the reselected carrier.

Optionally, the control unit is further configured to determine, according to the channel busy rate in the first indicator and the fifth correspondence, whether to perform carrier reselection on a carrier carrying the replicated copy of the target service data. Specifically, if the channel busy rate of the user equipment is higher than or equal to the sixth threshold, it is determined to reselect a carrier carrying the duplicate of the replicated target traffic data, and transmit the duplicate of the replicated target traffic data on the reselected carrier.

Specifically, as described above, when carrier reselection is performed, a carrier with the lowest channel busy rate may be selected from the first carrier set corresponding to the current target service data, and a copy of the copied target service data is transmitted. And if the K carriers are needed for copying and transmitting the data, selecting the carrier with the lowest busy rate of the K channels from the first carrier set. The low channel busy rate indicates that the occupancy rate of transmission resources on the carrier is low, the channel is not congested, and the interference of the copy of the target service data transmitted on the carrier is smaller, so that better transmission performance can be obtained. There are many other ways of reselection of the carrier, such as priority, etc., and are not described in detail herein.

In embodiment 10, it is considered that this carrier resource is indicated to be very congested when the channel busy rate is above a predetermined threshold, e.g. the sixth threshold in the above-described embodiment. In this case, even if a copy of the duplicated target service data is transmitted on this carrier, a large transmission collision may result. In view of this situation, the inventor of the present application proposes that carrier reselection can be performed based on actual situations, and that a carrier that is not congested (i.e., a carrier with a low channel busy rate) is selected for more efficient and guaranteed data transmission.
