Detailed Description

The present invention will be described in further detail with reference to the drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

The embodiment of the invention discloses a logic channel priority processing method and a logic channel priority processing device, which can be applied to a terminal for supporting at least two system parameter sets, wherein the terminal can be a mobile terminal with a wireless communication function; after the terminal establishes a connection with one cell, at least one data radio bearer may be established, and each data radio bearer may map at least one Logical Channel (LC).

Here, the system parameter set may include at least one of the following parameters: priority of each logical channel mapped to a system parameter set, discontinuous reception (Discontinuous Reception, DRX,) configuration information, hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) configuration information, uplink scheduling request (Scheduling Request, SR) resources, etc.; in practical implementation, the parameter configuration of the system parameter set may be default or configured to the terminal by signaling by the network side, such as the base station.

In an alternative example, after receiving an uplink resource (UL grant) schedule, the terminal uses the received uplink resource based on parameters in a system parameter set; for example, when a certain system parameter set includes DRX configuration information, after receiving uplink resource scheduling, the terminal may process data using the received uplink resource according to the DRX configuration information.

In another optional example, when a Transmission time interval (Transmission TIME INTERVAL, TTI) or a subframe is received, a plurality of uplink resource schedules are received, and the plurality of uplink resources respectively correspond to different system parameter sets, the plurality of uplink resources are used based on the set priority or priority sequence of each system parameter set; for example, the terminal receives two uplink resources in one TTI, which are respectively denoted as uplink resource 1 and uplink resource 2, where uplink resource 1 corresponds to system parameter set 1, uplink resource 2 corresponds to system parameter set 2, and priority of system parameter set 2 is higher than that of system parameter set 1, and at this time, the terminal may process data according to uplink resource 2 first, and then process data according to uplink resource 1.

The following embodiments are presented based on the terminal, the system parameter set, the logical channel, and the like presented above.

First embodiment

Fig. 1 shows a flowchart of a logical channel priority processing method according to an embodiment of the present invention, as shown in fig. 1, where the flowchart includes:

step 101: the priority or priority order of the respective system parameter sets is set.

Here, the priority or priority order of each system parameter set may be preset, and the priority order of each system parameter set is used to represent the priority level between each system parameter set; illustratively, the priority of each system parameter set may be represented by a positive integer, the lower the value of the priority of each system parameter set, which indicates the higher the priority of each system parameter set; or the lower the value of the priority of each system parameter set, the lower the priority of each system parameter set.

Obviously, the priority level between the respective system parameter sets may be determined according to the priority levels or the priority order of the respective system parameter sets, for example, three system parameter sets supported by the terminal are denoted as n1, n2, and n3, respectively, and in one example, n1, n2, and n3 may be sequentially arranged as n2, n3, and n1 in order of priority levels from high to low.

Step 102: and sequentially carrying out logic channel priority processing according to the priority or priority sequence of each system parameter set.

It can be seen that, according to the logic channel priority processing method of the first embodiment of the present invention, logic channel priority processing can be sequentially performed according to the priority or priority sequence of each system parameter set, and since each system parameter set can correspond to one type of communication service, the priority or priority sequence of the system parameter set can be used to characterize the communication requirement (such as a delay requirement) of each type of communication service, so that when logic channel priority processing is performed according to the priority or priority sequence of each system parameter set, the terminal can adapt to different requirements of different services when processing uplink data in a wireless environment supporting multiple system parameter sets.

For example, before the logic channel priority processing is sequentially performed according to the priority or priority order of each system parameter set, when at least two logic channels are mapped to one system parameter set, the priority or priority order of each logic channel mapped to the system parameter set may be set; that is, if at least two logical channels are mapped to the jth system parameter set, the priority or priority order of the respective logical channels mapped to the jth system parameter set may be set, j being greater than or equal to 1.

In one example, where two logical channels mapped to the jth system parameter set are denoted as A1 and A2, respectively, the priorities of A1 and A2, or the order of priority of A1 and A2, may be set.

Here, the priority order of each logical channel mapped to the corresponding system parameter set is used to represent the priority level between each logical channel according to a similar manner of setting the priority or priority order of each system parameter set; illustratively, the priority of each logical channel may be represented by a positive integer, the lower the value of the priority of each logical channel, indicating the higher the priority of each logical channel; or the lower the value of the priority of each logical channel, the lower the priority of each logical channel.

It should be noted that, the priority or priority order of each logical channel mapped to the corresponding system parameter set is independent from the priority or priority order of each system parameter set.

Accordingly, the logic channel priority processing is sequentially performed according to the priority or priority sequence of each system parameter set, which may include

When at least two logical channels are mapped to one system parameter set, according to the priority or priority sequence of each logical channel mapped to the corresponding system parameter set, sequentially carrying out the priority processing of the logical channels of the corresponding system parameter set;

when only one logical channel is mapped to one system parameter set, logical channel priority processing of the corresponding system parameter set is performed.

That is, when at least two logical channels are mapped to the jth system parameter set, uplink data of each logical channel mapped to the jth system parameter set may be processed according to the priority or priority order of each logical channel mapped to the jth system parameter set; when only one logical channel is mapped to the jth system parameter set, uplink data mapped to the logical channel of the jth system parameter set is processed.

It can be seen that in the implementation of the present invention, the uplink data processing mode can be flexibly determined according to the number of logical channels mapped to each system parameter set; in addition, when at least two logical channels are mapped to one system parameter set, uplink data can be processed according to the priority or priority order of each logical channel mapped to the corresponding system parameter set, in this way, the processing mode of the uplink data is in accordance with the priority of the logical channel, and when the priority or priority order of each logical channel mapped to the corresponding system parameter set is determined according to the actual service requirement, the processing mode of the uplink data can meet the actual service requirement.

Illustratively, before sequentially performing the logical channel priority processing according to the priority or the priority order of the respective system parameter sets, the method further includes:

Each logical channel maintains a logical channel multiplexing factor, which can be noted as a variable Bj; the variable Bj has an initial value of 0, and the variable Bj is used to represent the data amount that is allowed to be processed preferentially on the corresponding logical channel. Here, the variable Bj is independent of the system parameter set corresponding to the logical channel, and the variable Bj is the same for the same logical channel mapped to a different system parameter set.

The variable Bj is exemplarily described below with reference to a token bucket algorithm (Token bucket algorithm) of the LTE system.

In the LTE system, the token bucket algorithm is always applied to the terminal to process uplink data, and when in implementation, each logical channel is configured with the following parameters: priority (priority), priority rate (Prioritized Bit Rate, PBR) and duration parameter (Bucket Size Duration, BSD), the capacity of the token bucket is PBR multiplied by BSD, the terminal maintains a logical channel multiplexing factor, i.e. variable Bj, for each logical channel, which changes in each TTI;

Fig. 2 shows a schematic diagram of a change in a value of a variable Bj of a logical channel in an LTE system, and in fig. 2, UL grant indicates an uplink scheduling grant resource, it can be seen that the value of the variable Bj increases PBR by TTI in each TTI; when the token bucket algorithm is adopted for data processing, new tokens are increased, and old tokens are consumed due to the processed data; the process of uplink data processing using the token bucket algorithm may be referred to as a logical channel priority process, in which, if uplink resources are available, the logical channel processes the uplink data in a priority order and token bucket.

Here, the LCP procedure may include: firstly, using uplink resources according to a priority order for a logic channel with a variable Bj larger than 0; secondly, subtracting the data quantity of the current processed uplink data of the corresponding logic channel from the value of the variable Bj for each logic channel using the uplink resource to obtain an updated variable Bj, wherein the processed data quantity represents the data quantity of the current processed uplink data of the corresponding logic channel in FIG. 2; thirdly, if the uplink resources are remained, using the uplink resources by all the logic channels according to the priority order; it should be noted that the logical channels with the same priority will be treated equally.

In the embodiment of the invention, the PBR and the BSD are configured for each logic channel, the value of the variable Bj is maintained for the logic channel, the increment can be carried out in each TTI, the increment is the same in each increment, and the value of the variable Bj does not exceed the capacity of the token bucket.

Accordingly, the processing of the logical channel priorities of the corresponding system parameter sets according to the priorities or the priority orders of the respective logical channels mapped to the corresponding system parameter sets sequentially includes:

in each logic channel mapped to a corresponding system parameter set, if the number of logic channels with the variable Bj larger than 0 is larger than 1, sequentially processing uplink data of each logic channel with the variable Bj larger than 0 according to the data quantity represented by the variable Bj of each logic channel with the variable Bj larger than 0 and the priority of each logic channel with the variable Bj larger than 0 from high to low;

in each logic channel mapped to a corresponding system parameter set, if the number of logic channels with the variable Bj being greater than 0 is equal to 1, processing uplink data of the logic channels with the variable Bj being greater than 0 according to the data quantity represented by the variable Bj;

And in each logic channel mapped to the corresponding system parameter set, if the number of logic channels with the variable Bj larger than 0 is equal to 0, sequentially processing uplink data of each logic channel mapped to the corresponding system parameter set according to the order of priority of each logic channel mapped to the corresponding system parameter set from high to low.

That is, when uplink data is processed using each logical channel mapped to a corresponding system parameter set, flexible processing of the uplink data can be achieved according to the number of logical channels whose variable Bj is greater than 0.

Optionally, when the number of logical channels whose variable Bj is greater than 0 is greater than 1, sequentially processing uplink data of each logical channel whose variable Bj is greater than 0 according to the data amount represented by the variable Bj of each logical channel whose variable Bj is greater than 0 and in the order of priority of each logical channel whose variable Bj is greater than 0 from high to low, including:

Sequentially marking each logic channel with the variable Bj greater than 0 as a1 st logic channel to a K logic channel according to the order of the priority of each logic channel with the variable Bj greater than 0 from high to low, wherein K is greater than 1; for example, three logical channels with a variable Bj greater than 0 are denoted as A3, A4, and A5, respectively, and the three logical channels A3, A4, and A5 may be arranged in order of priority from high to low: a4, A3, and A5, then logical channel A4 is the 1 st logical channel, logical channel A3 is the 2 nd logical channel, and logical channel A5 is the 3 rd logical channel.

When the uplink data of the kth logic channel is processed, if the data amount of the uplink data of the kth logic channel is smaller than or equal to the data amount represented by the variable Bj of the kth logic channel, processing all the uplink data of the kth logic channel, and then, if the kth+1 logic channel exists, processing the uplink data of the kth+1 logic channel; if the data quantity of the uplink data of the kth logic channel is larger than the data quantity represented by the variable Bj of the kth logic channel, dividing the uplink data of the kth logic channel into priority processing data and residual data, processing the priority processing data of the kth logic channel, and after each logic channel with the variable Bj larger than 0 completes one time of uplink data processing, if the kth logic channel has available residual resources, processing the residual data of the kth logic channel; wherein the data amount of the priority processing data of the kth logical channel is equal to the data amount represented by the variable Bj of the kth logical channel.

For example, for the kth logical channel, if the data amount of the uplink data of the kth logical channel is C1, the data amount represented by the variable Bj of the kth logical channel is C2, and C1 is greater than C2, the uplink data of the kth logical channel is divided into priority processing data and remaining data, the data amount of the priority processing data is C2, and the data amount of the remaining data is C1-C2; at this time, it is necessary to process the uplink data once on each logical channel according to the order from the 1 st logical channel to the K logical channel, wherein the uplink data of the K logical channel is the priority processing data described above, and after the 1 st logical channel to the K logical channel have processed the uplink data once, the remaining data of the K logical channel is processed.

It should be noted that, in the 1 st to the K th logical channels, if the data amount of the uplink data of at least two logical channels is greater than the variable Bj of the corresponding logical channel, the uplink data may be processed on the corresponding logical channels according to the order of the priority of each logical channel for processing the remaining data from high to low after the 1 st to the K th logical channels have processed the uplink data once.

For example, when K is taken as 5, if the data amount of the uplink data of the 2 nd logical channel is greater than the variable Bj of the 2 nd logical channel and the data amount of the uplink data of the 3 rd logical channel is greater than the variable Bj of the 3 rd logical channel, after all of the 1 st logical channel to the K logical channel process the uplink data once, the 2 nd logical channel and the 3 rd logical channel are adopted to process the remaining data in the order of the priority of the 2 nd logical channel and the 3 rd logical channel from high to low.

Optionally, when the logical channel with the variable Bj greater than 0 is equal to 1, if the data size of the uplink data of the logical channel with the variable Bj greater than 0 is smaller than or equal to the data size represented by the variable Bj of the corresponding logical channel, directly processing the uplink data of the logical channel with the variable Bj greater than 0;

If the data size of the uplink data of the logical channel with the variable Bj being greater than 0 is greater than the data size represented by the variable Bj of the corresponding logical channel, in an alternative embodiment, the uplink data of the logical channel with the variable Bj being greater than 0 is divided into priority processing data and residual data, the priority processing data of the logical channel with the variable Bj being greater than 0 is processed, and then if the logical channel with the variable Bj being greater than 0 has available residual resources, the residual data of the logical channel with the variable Bj being greater than 0 is processed; wherein, the data volume of the preferential processing data of the logic channel with the variable Bj larger than 0 is equal to the data volume represented by the variable Bj of the logic channel with the variable Bj larger than 0; in an alternative embodiment, all of the upstream data of the logical channels with variable Bj greater than 0 may be processed directly.

For example, when the logical channel with the variable Bj greater than 0 is equal to 1, the logical channel with the variable Bj greater than 0 is denoted as a logical channel A6, the data amount of the uplink data of the logical channel A6 is denoted as C3, and the data amount represented by the variable Bj set in the logical channel A6 is denoted as C4; if C3 is less than or equal to C4, the uplink data of the logic channel A6 can be processed directly; if C3 is greater than C4, the priority processing data for logical channel A6 may be processed first, followed by the remaining data for logical channel A6.

In actual implementation, for each logical channel with variable Bj greater than 0, after each uplink data processing, variable Bj is updated, and the data amount represented by the updated variable Bj is: the difference value obtained by subtracting the data quantity of the uplink data processed by the corresponding logic channel from the data quantity represented by the variable Bj before updating.

For example, a logical channel with a variable Bj greater than 0 is denoted as a logical channel A7, the data amount represented by the variable Bj before update is denoted as C5 for the logical channel A7, the data amount of the uplink data currently processed by the logical channel A7 is denoted as C6, and the data amount represented by the variable Bj after update is denoted as C5-C6.

Specifically, when the priority processing of the logic channels of the corresponding system parameter set is sequentially performed according to the priority or the priority order of each logic channel mapped to the corresponding system parameter set, when at least two logic channels with the same priority or priority order exist in each logic channel mapped to the corresponding system parameter set, the uplink data is processed by adopting a preset public flat policy for the uplink data of each logic channel with the same priority or priority order.

Optionally, the preset fairness policy may be: the uplink data of each logic channel with the same priority or priority order is processed randomly, or a part of the uplink data of each logic channel with the same priority or priority order is processed each time.

In practical implementation, the uplink data corresponding to each system parameter set may include uplink data of a logical channel that is not mapped to the corresponding system parameter set, for example, the uplink data corresponding to the jth system parameter set includes uplink data of a logical channel a10, but the logical channel a10 is not mapped to the jth system parameter set, for which the following two ways may be used for data processing:

In the first mode, after the uplink data of each logical channel mapped to the corresponding system parameter set is processed, the uplink data of the logical channel not mapped to the corresponding system parameter set is processed; that is, the logical channels that are not mapped to the corresponding system parameter set are treated as the logical channels with the lowest priority.

In the second mode, after the next uplink resource mapped to the corresponding logical channel of the mth system parameter set is acquired, the corresponding uplink data is processed.

Here, the uplink resources of each system parameter set represent authorized resources that may be used to process uplink data, and the embodiment of the present invention does not limit the types of uplink resources.

Second embodiment

In order to further embody the object of the present invention, further illustration is made on the basis of the first embodiment of the present invention.

In this embodiment, the terminal establishes a connection with the cell 1, three data radio bearers established by the terminal and the cell 1 are RB3, RB4 and RB5, respectively, and table 1 shows the parameter configurations of these several data radio bearers.

Data radio bearer	Corresponding LC	Bj	Bucket size
				RB3	LC1	Bj1	Bucket size 1
RB4	LC2	Bj2	Bucket size 2
				RB5	LC3	Bj3	Bucket size 3

In table 1, LC2 and LC3 respectively represent three logical channels, bj1, bj2 and Bj3 respectively represent three different variables Bj of the logical channel setting, socket size represents token Bucket capacity, socket size1, socket size2 and socket size3 respectively represent three different token Bucket capacities corresponding to the three logical channels, and it can be seen that each data radio bearer in table 1 corresponds to one logical channel.

The terminal supports three system parameter sets, which are respectively denoted as N1, N2 and N3, and are arranged as N1, N2 and N3 in order of priority from high to low, and table 2 shows a priority setting manner of LC in each system parameter set.

In addition, in order to represent the priority levels of the respective logical channels mapped to each system parameter set, the absolute priority levels of the logical channels shown in table 3 may be set instead of the priority order setting method shown in table 2, and in table 3, if the absolute priority levels of the logical channels are smaller for one system parameter set, it is indicated that the priority levels of the logical channels are higher,

TABLE 3 Table 3

The following describes the uplink data processing procedure of the second embodiment of the present invention by referring to fig. 3-1 to 3-8, in which the rectangular frame filled with dots corresponds to N1, the rectangular frame filled with oblique lines corresponds to N2, the rectangular frame filled with vertical lines corresponds to N3, and the positions (heights) where the characters Bj1, bj2, and Bj3 are located represent the data amounts represented by the current variables Bj1, bj2, and Bj3, respectively.

At time T1, the data buffers of the three data radio bearers are shown in fig. 3-1, and in fig. 3-1, character 1 in the rectangular frame represents uplink data mapped to LC1 of N1 and is denoted as data 1; the character 2-1 in the rectangular frame represents the priority processing data of the uplink data mapped to LC2 of N1, denoted as data 2-1, and the character 2-2 in the rectangular frame represents the remaining data of the uplink data mapped to LC2 of N1, denoted as data 2-2; character 3 in the rectangular frame represents the uplink data of LC3 mapped to N1, denoted as data 3; character 4 in the rectangular frame represents the uplink data of LC2 mapped to N2, denoted as data 4; character 5 in the rectangular box represents the uplink data of LC3 mapped to N2, denoted as data 5; character 6 in the rectangular frame represents the upstream data of LC1 mapped to N2, denoted as data 6; character 7 in the rectangular frame represents the upstream data of LC3 mapped to N3, denoted as data 7; character 8 in the rectangular frame represents the uplink data of LC1 mapped to N3, denoted as data 8; the character 9 in the rectangular box represents the upstream data of LC2 mapped to N3, denoted as data 9. In fig. 3-2 to 3-8, the meaning of the characters within the rectangular frame is the same as in fig. 3-1.

In fig. 3-1, LCG2 and LCG3 represent three different logical channel groups, respectively, where LC1 corresponds to LCG1, LC2 corresponds to LCG2, LC3 corresponds to LCG3, and in fig. 3-2, 3-3, 3-5 and 3-6, LCG1, LCG2 and LCG3 have the same meaning as in fig. 3-1.

In fig. 3-1, the amount of data currently represented by Bj1 is equal to the amount of data 1, the amount of data 2-2 is equal to the amount of data currently represented by Bj2, and the amount of data 3 is smaller than the amount of data currently represented by Bj 3.

At time T2, the terminal receives the uplink resource corresponding to N1, the uplink resource corresponding to N2, and the uplink resource corresponding to N3 in the cell 1, where the terminal may process the uplink data according to the priority of the system parameter set, and the following steps are performed:

1) Firstly, processing N1 data with highest priority, and sequentially processing uplink data mapped to logic channels LC1, LC2 and LC3 of N1 according to the order from high to low of LC in N1, wherein the data 1 and the data 3 can be processed at one time, and the uplink data mapped to the logic channel LC2 of N1 is larger than the current data quantity represented by Bj2, so that data 2-2 is processed firstly; after all three logical channels mapped to N1 are processed once for uplink data, a schematic diagram of the data buffers of the data radio bearer is shown in fig. 3-2.

Here, after the uplink data processing is performed on each of the three logical channels mapped to N1, the values of Bj1, bj2, and Bj3 need to be updated, and the updating method has been described in the first embodiment of the present invention; in fig. 3-2, the values of Bj1 and Bj2 are 0 (the data amounts currently represented by Bj1 and Bj2 are 0), and the data amount represented by Bj3 is smaller than the data amount of data 5; it can be seen that at this point, data 2-2 has not been processed.

2) Data 2-2 is processed using logical channel LC2, where a schematic diagram of the data buffers of the data radio bearer is shown in fig. 3-3.

After the data 2-2 is processed by adopting the logic channel LC2, the data 5 can be divided into two parts according to the current data quantity represented by Bj3, wherein one part is the preferential processing data of LC3 and the other part is the residual data of LC 3; in fig. 3-3, character 5-1 in the rectangular frame represents the priority processing data of LC3, denoted as data 5-1, and the data amount is the data amount currently represented by Bj 3; character 5-2 within the rectangular box represents the remaining data of LC 3.

Fig. 3-4 show the order of processing data using uplink resources on N1, and in fig. 3-4, N1-UL grant indicates uplink resources used on N1, it can be seen that the order of processing data using uplink resources on N1 is: data 1, data 2-1, data 3, data 2-2.

3) At this time, according to the priority order of the three system parameter sets, the uplink data on N2 needs to be processed; specifically, since the data amounts represented by Bj corresponding to LC1 and LC2 are all 0, and the data amount represented by Bj corresponding to LC3 (i.e., bj 3) is greater than 0, it is necessary to process data 5-1 first, and after the processing of data 5-1 is completed, a schematic diagram of the data buffer of the data radio bearer is shown in fig. 3-5.

4) At this time, data 4, data 5-2 and data 6 are sequentially processed in order of priority of each logical channel mapped to N2 from high to low, and after the processing is completed, the schematic diagrams of the data buffers of the data radio bearers are shown in fig. 3-6.

5) And finally, processing uplink data on the N3, specifically, sequentially processing the data 7, the data 8 and the data 9 according to the order of the priority of each logic channel in the N3 from high to low, wherein after the processing is finished, a data buffer area of the data wireless bearing is empty.

Fig. 3 to 8 show the order of processing data using uplink resources on N3, and in fig. 3 to 8, N3-UL grant indicates uplink resources used on N3, it can be seen that the order of processing data using uplink resources on N3 is: data 7, data 8 and data 9.

In the above embodiment, if the priorities of multiple LCs in the same system parameter set are the same, the LC data with the same priority is processed fairly, for example, according to the first embodiment of the present invention, the data processing process of the LCs with the same priority may be performed,

If there are only two LCs mapped into a certain system parameter set, then data that is not mapped into an LC of the corresponding system parameter set cannot be processed (can be processed after waiting for the next acquisition of the uplink resources of the system parameter set), or is processed when the priority is lowest.

Third embodiment

In a third embodiment of the present invention, several implementations of sequentially performing the logical channel priority processing according to the priorities or the priority orders of the respective system parameter sets are exemplarily described.

Here, the respective system parameter sets may be sequentially written as 1 st to M-th system parameter sets in order of priority of the respective system parameter sets from high to low, with M being greater than 1.

Optionally, the processing of logical channel priority is sequentially performed according to the priority or the priority sequence of each system parameter set, including:

When the M-th system parameter set has remained uplink resources after all the logic channels mapped to the M-th system parameter set process respective uplink data, if the m+1th system parameter set has data, processing additional data by using the remained uplink resources of the M-th system parameter set, wherein the additional data comprises: uplink data of at least one logical channel mapped to the (m+1) -th system parameter set;

Processing the remaining uplink data of the (m+1) th system parameter set by adopting the uplink resource of the (m+1) th system parameter set, wherein the remaining uplink data of the (m+1) th system parameter set is as follows: and removing the data after the additional data from the uplink data of each logic channel mapped to the (m+1) th system parameter set.

Further, when at least two logical channels are mapped to the (m+1) -th system parameter set, selecting at least one logical channel from all the logical channels mapped to the (m+1) -th system parameter set according to the order of the priority of the logical channels from high to low, wherein the total data volume of uplink data of the selected logical channel is smaller than or equal to the data volume of remaining uplink resources of the (m) -th system parameter set, which allows processing;

And processing the uplink data of the selected logical channel by using the residual uplink resources of the mth system parameter set.

That is, after all the logical channels mapped to the mth system parameter set have processed the respective uplink data, if the mth system parameter set still has remaining uplink resources, the data on the (m+1) th system parameter set can be processed by using the remaining uplink resources, so that the utilization efficiency of the uplink resources of the mth system parameter set can be improved.

after all logic channels mapped to the ith system parameter set process respective uplink data, when the ith system parameter set still has residual uplink resources, processing filling (padding) data by using the residual uplink resources of the ith system parameter set, wherein the value range of i is 1 to M; therefore, when each system parameter set has residual uplink resources, uplink data of other system parameter sets are not processed, and as each system parameter set can be set according to actual service requirements, the processing mode of the uplink data can be more in line with the actual service requirements and can meet different requirements of different services.

Here, the data size of the padding data is the data size allowed to be processed by the remaining uplink resources of the ith system parameter set, and the embodiment of the present invention does not limit the generation manner of the padding data.

When the total data quantity of the uplink data of each logic channel mapped to the mth system parameter set is larger than the allowable processing data quantity of the uplink resource of the mth system parameter set and the uplink resource of the mth system parameter set is used up, processing the remaining uplink data of the mth system parameter set after the next acquisition of the uplink resource of the mth system parameter set; or when the uplink resources of the (m+1) th system parameter set exist, adopting the uplink resources of the (m+1) th system parameter set to process the residual uplink data of the (m) th system parameter set; wherein, the remaining uplink data of the mth system parameter set is: when the uplink resource of the mth system parameter set is used up, the unprocessed data in the uplink data of each logic channel mapped to the mth system parameter set, and the value range of M is 1 to M.

That is, if there is data in the mth system parameter set after the use of the uplink resource of the mth system parameter set is completed, in one embodiment, the processing of the remaining uplink data of the mth system parameter set may be performed in the next acquisition of the uplink resource of the mth system parameter set, so that it may be ensured that the uplink data of each system parameter set may only be processed by using the corresponding system parameter set; in another embodiment, the remaining uplink data of the (m+1) -th system parameter set may be processed by using the uplink resource of the (m+1) -th system parameter set, so that the processing efficiency of the data of the system parameter set with higher priority may be ensured.

For the implementation manner of processing the remaining uplink data of the mth system parameter set by using the uplink resource of the mth+1th system parameter set, in one implementation manner, after processing the remaining uplink data of the mth system parameter set by using the uplink resource of the mth+1th system parameter set, the uplink data mapped to each logic channel of the mth+1th system parameter set may be processed by using the uplink resource of the mth+1th system parameter set; in another embodiment, the uplink data mapped to each logical channel of the (m+1) -th system parameter set may be processed using the uplink resources of the (m+1) -th system parameter set before the remaining uplink data of the (m) -th system parameter set are processed using the uplink resources of the (m+1) -th system parameter set.
