Description

CCE allocation method, device, network equipment and storage medium

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a CCE allocation method, a CCE allocation device, network equipment and a storage medium.

Background

In the fifth generation mobile communication technology (english: 5th Generation Mobile Communication Technology, abbreviated as 5G) system, a control channel element (english: control Channel Element, abbreviated as CCE) resource is used on a physical layer downlink control channel (english: physical Downlink Control Channel, abbreviated as PDCCH), control information for scheduling downlink grants of a physical layer downlink shared channel (english: physical Uplink Shared Channel, abbreviated as PDSCH) is transmitted, and control information for scheduling uplink grants of a physical layer uplink shared channel (english: physical Uplink Shared Channel, abbreviated as PUSCH) is transmitted.

In the multi-user scheduling scenario, CCE resources need to be allocated in order to reduce the cases where CCE resources are exclusively used by grant information in a certain direction.

In the related art, CCEs are allocated for uplink users and downlink according to a preset ratio, that is, a fixed number of CCEs are used for uplink and downlink.

However, the above approach does not refer to specific requirements for upstream and downstream. If the number of users in a certain direction is large, more CCEs are needed, but the CCE allocation failure can be caused due to fixed proportion; in the direction of less users, many idle CCEs can be used, so that CCE resource waste is caused. Therefore, the above approach cannot achieve CCE rational allocation.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the description of the present application, it should be noted that, unless explicitly stated and limited otherwise, the term "connected" should be interpreted broadly, and for example, it may be directly connected, or it may be indirectly connected through an intermediate medium, or it may be communication between two devices. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.

And using CCE resources on the PDCCH in the 5G system, transmitting control information for scheduling downlink grant of the PDSCH, and transmitting control information for scheduling uplink grant of the PUSCH.

In some embodiments, the ratio of the downlink CCEs is adjusted by calculating the uplink CCE usage rate within a period of time, and when the uplink CCE usage rate is greater than the uplink high threshold, the ratio of the downlink CCEs is adjusted down, so as to dynamically adjust the ratio of the uplink CCEs to the downlink CCEs.

However, the demands of uplink and downlink on CCEs are dynamically changed, and even according to the historical CCE utilization, the current CCE demand may not be satisfied, for example, the base station side wants to schedule a large number of uplink users, but the historical uplink grant CCE utilization is low, the ratio of CCEs of the uplink grant is small, and the scheduling of the uplink users may not be satisfied. Therefore, although this method realizes dynamic CCE allocation, the allocation method is not reasonable.

In view of this, an embodiment of the present application proposes a CCE allocation method, apparatus, network device, and storage medium, where the method includes: determining the expected CCE number of each uplink user and the expected CCE number of each downlink user in a target TTI; determining the expected CCE quantity of each uplink user based on the channel quality indication of each uplink user; determining the expected CCE quantity of each downlink user based on the channel quality indication of each downlink user; determining a target CCE number based on a sum of an uplink expected total number and a downlink expected total number; wherein, the uplink expected total number is the sum of expected CCE numbers of all uplink users, and the downlink expected total number is the sum of expected CCE numbers of all downlink users; and performing CCE allocation based on a comparison result between the target CCE number and the number of available CCEs of the current TTI.

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems with reference to the drawings and specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

Fig. 1 is a flow chart of a first CCE allocation method provided in an embodiment of the present application, as shown in fig. 1, including the following steps:

step S101: and determining the expected CCE number of each uplink user and the expected CCE number of each downlink user in the target TTI.

In this embodiment, the target TTI may be each TTI, or any TTI in each period (a period may include multiple TTIs), or the next TTI when determining CCE allocation imbalance, etc., and may be specifically set according to practical applications.

And determining all uplink users and all downlink users needing to be scheduled in the target TTI.

For example, through a scheduling module, a Round Robin (r) algorithm, an orthogonal fair scheduling (Proportional Fail, PF) algorithm, or other common scheduling algorithm of a base station medium access control (Medium Access Control, MAC) layer is used to schedule multiple users, so as to achieve fairness of user scheduling and quality of service (QoS, quality of Service) of the users, and output uplink users and downlink users to be scheduled in a target TTI.

In this embodiment, for each uplink user that needs to be scheduled, the corresponding expected CCE number (i.e., the number of CCEs required by the uplink user) is determined based on the channel quality indication of the uplink user; for each downlink user needing to be scheduled, determining a corresponding expected CCE number (namely the required CCE number) based on the channel quality indication of the downlink user; thereby taking into account the needs of all users that need to be scheduled.

Step S102: the target CCE number is determined based on a sum of the uplink expected total number and the downlink expected total number.

Wherein the uplink expected total number is the sum of expected CCE numbers of all uplink users, and the downlink expected total number is the sum of expected CCE numbers of all downlink users.

In this embodiment, all uplink users are integrated to obtain the expected total number of uplink (the total number of CCEs required by the uplink users) in the TTI; and integrating all downlink users to obtain the expected total number (the total number of CCEs required by the downlink users) of the downlink in the TTI.

Illustratively, the expected total number of uplinksWherein, CCE_NUM _i The expected CCE number of the ith uplink user is equal to or more than 1 and equal to or less than n, and n is the total number of the uplink users;

total number of downlink expectationsWherein, CCE_NUM _j The expected CCE quantity of the jth downlink user is more than or equal to 1 and less than or equal to m, and m is the total number of the downlink users;

target CCE number all_exp_cce_num=ul_all_exp_cce_num+dl_all_exp_cce_num.

Step S103: and performing CCE allocation based on a comparison result between the target CCE number and the number of available CCEs of the current TTI.

In some alternative embodiments, the number of available CCEs for the current TTI may be determined by, but not limited to, the following:

In practice, different numbers of PDCCHs under orthogonal frequency division multiplexing (English: orthogonal Frequency Division Multiplexing, abbreviated OFDM) symbols correspond to different CCE total numbers. At a bandwidth of 100MHZ, the total number of CCEs can be found as shown in table 1:

TABLE 1

PDCCH symbol number	Total number of CCEs
		1	45
2	90
		3	135

Table 1 is merely an example, and the present embodiment does not specifically limit the total number of CCEs.

In the implementation, the common scheduling information also needs CCE resources, CCE is allocated to the common scheduling information, and the rest of the common scheduling information can be allocated to uplink and downlink users;

based on this, the present embodiment determines the difference between the total number of CCEs and the number of common scheduling CCEs of the current TTI as the number of available CCEs, which are available CCEs for uplink and downlink users, and only those CCEs participate in subsequent uplink and downlink allocation.

The embodiment does not specifically limit the above-mentioned common scheduling messages, such as system information block1 (english: system Information Block, abbreviated SIB 1), other system messages (english: other System Information, abbreviated Other SI), paging (english: paging) messages, random access reply (english: random Access Response, abbreviated RAR) messages, contention resolution (english: contention Resolution, abbreviated CR) messages, common control channel (english: common Control Channel, abbreviated CCCH), and the like.

In some alternative embodiments, the step S102 may be implemented by, but not limited to, the following ways:

In this embodiment, the expected CCE number of each uplink/downlink user may be determined directly based on the channel quality indication; the expected number of CCEs for each uplink/downlink user may also be determined in combination with the weight values.

In some alternative embodiments, determining the desired number of CCEs for each uplink user based on the channel quality indication for each uplink user at the target TTI may be accomplished by, but is not limited to, the following:

based on a third preset corresponding relation, determining the number of CCEs corresponding to channel quality indication (English: channel Quality Indicator, abbreviated as CQI) of any uplink user as the expected number of CCEs of the uplink user;

based on the channel quality indication for each downlink user at the target TTI, determining the desired number of CCEs for each downlink user may be accomplished by, but is not limited to, the following:

In the implementation, if the channel quality indication is larger, the channel quality is better, and in order to reduce the waste of CCE resources, the transmission requirement can be met by using fewer CCEs; if the channel quality indication is smaller, the channel quality is worse, more CCEs need to be allocated to bear the control information of single authorization so as to ensure effective transmission;

Based on this, a third preset corresponding relation is provided in this embodiment, where the third preset corresponding relation includes a correspondence between a channel quality indication and the number of CCEs, and the larger the channel quality indication is, the smaller the number of CCEs is;

and determining the quantity of CCEs corresponding to the channel quality indication of the uplink/downlink user as the expected quantity of the CCEs of the uplink/downlink user, so that the expected quantity of the CCEs accurately reflects the CCE requirements of the corresponding user.

The third preset correspondence may be shown in table 2:

Wherein, Z1-Z15 are gradually decreased in whole, i.e. Z1 is more than Z2 and more than … … is more than Z14 and more than Z15; alternatively, there may be some CCEs that are adjacent to each other in the same number, for example, z1=z2 > z3=z4 … … > z14=z15, and the present embodiment is not limited thereto.

The above table 2 is merely illustrative, and the third preset correspondence relationship is not specifically limited in this embodiment.

Fig. 2 is a flow chart of a second CCE allocation method provided in an embodiment of the present application, where, as shown in fig. 2, the method includes the following steps:

step S201: and determining the expected CCE number of each uplink user and the expected CCE number of each downlink user in the target TTI.

Step S202: the target CCE number is determined based on a sum of the uplink expected total number and the downlink expected total number.

The specific implementation manner of the steps S201 to S202 may refer to the above embodiment, and will not be described herein.

Step S203: and if the target CCE number is smaller than or equal to the available CCE number, allocating the CCE with the corresponding expected CCE number for each uplink user, and allocating the CCE with the corresponding expected CCE number for each downlink user.

In the implementation, if the number of the target CCEs is smaller than or equal to the number of the available CCEs, the large probability of the available CCEs is indicated to be capable of meeting the CCE requirements of all uplink and downlink users;

based on this, in this embodiment, CCEs of a desired number of CCEs are allocated to each uplink user, and CCEs of a desired number of CCEs are allocated to each downlink user.

The embodiment does not specifically limit the specific allocation manner, and is exemplary:

firstly, distributing CCEs with the corresponding expected CCE number to each uplink user, and distributing CCEs with the corresponding expected CCE number to the downlink user after the uplink user CCE is distributed;

or firstly, distributing the CCEs with the corresponding expected CCE number for each downlink user, and then distributing the CCEs with the corresponding expected CCE number for the uplink user after the downlink user CCE distribution is completed.

Fig. 3 is a flow chart of a third CCE allocation method provided in an embodiment of the present application, where, as shown in fig. 3, the method includes the following steps:

step S301: and determining the expected CCE number of each uplink user and the expected CCE number of each downlink user in the target TTI.

Step S302: the target CCE number is determined based on a sum of the uplink expected total number and the downlink expected total number.

The specific implementation manner of the steps S301 to S302 may refer to the above embodiment, and will not be described herein.

Step S303: and if the target CCE number is greater than the available CCE number, determining a weight value corresponding to each uplink user and determining a weight value corresponding to each downlink user.

In the implementation, if the number of the target CCEs is greater than the number of the available CCEs, the available CCEs cannot meet the CCE requirements of all uplink and downlink users; weight information of uplink and downlink scheduling needs to be considered, and CCEs are selectively allocated to uplink and downlink users;

based on this, the present embodiment needs to determine the weight value corresponding to each uplink user and the weight value corresponding to each downlink user for performing the subsequent weighting calculation.

Step S304: based on the weight values corresponding to all uplink users, carrying out weighted calculation on the expected CCE numbers of all uplink users to obtain the uplink weighted expected total number; and carrying out weighted calculation on the expected CCE quantity of all the downlink users based on the weight values corresponding to all the downlink users to obtain the downlink weighted expected total number.

As described above, if the target CCE number is greater than the number of available CCEs, it is indicated that the available CCEs cannot meet CCE requirements of all uplink and downlink users; the number of expected CCEs is adjusted by considering the weight information of uplink and downlink scheduling, namely the uplink weighted expected total number and the downlink weighted expected total number are the numbers after weight adjustment, so that CCEs are selectively allocated to uplink and downlink users based on the weight information of uplink and downlink scheduling;

based on this, in this embodiment, after determining the weight value corresponding to each uplink user and the weight value corresponding to each downlink user, the number of expected CCEs of all uplink users needs to be weighted based on the weight values corresponding to all uplink users, so as to obtain an uplink weighted expected total number; and carrying out weighted calculation on the expected CCE quantity of all the downlink users based on the weight values corresponding to all the downlink users to obtain the downlink weighted expected total number.

Step S305: and determining a first uplink quantity and a first downlink quantity based on the uplink weighted expected total number, the downlink weighted expected total number and the quantity of the available CCEs.

The uplink weighted expected total number is a weighted adjustment of the expected CCE number of the uplink user, and the downlink weighted expected total number is a weighted adjustment of the expected CCE number of the downlink user; it is also necessary to refer to the number of available CCEs to determine a first uplink number defining uplink allocations and a first downlink number defining downlink allocations.

Step S306: and performing CCE allocation based on the first uplink number or the first downlink number.

As described above, the first uplink number defines uplink allocation, and the first downlink number defines downlink allocation; based on the first uplink number or the first downlink number, allocation limitation is performed on one direction, and CCEs are allocated to uplink and downlink users more selectively by combining weight information of uplink and downlink scheduling.

In some optional embodiments, the determining the weight value corresponding to each uplink user may be implemented by, but not limited to, the following manner:

based on a first preset corresponding relation, determining a weight value corresponding to the service type of any uplink user as the weight value corresponding to the uplink user;

the first preset corresponding relation comprises the correspondence between the uplink service type and the weight value, and the higher the priority of the uplink service type is, the larger the corresponding weight value is.

In some optional embodiments, the above determination of the weight value corresponding to each downlink and uplink user may be implemented by, but not limited to, the following ways:

based on a second preset corresponding relation, determining a weight value corresponding to the service type of any downlink user as the weight value corresponding to the downlink user;

the second preset corresponding relation comprises the correspondence between the downlink service type and the weight value, and the higher the priority of the downlink service type is, the larger the corresponding weight value is.

Because the priorities of different service types are different, CCEs need to be allocated for the corresponding uplink users/downlink users preferentially aiming at the service type with high priority, so that the normal operation of the service is ensured.

Based on this, the embodiment sets a first preset corresponding relation between the uplink service type and the weight value, and the higher the priority of the uplink service type is, the larger the corresponding weight value is;

and determining a weight value corresponding to the service type of the uplink user as the weight value corresponding to the uplink user based on the first preset corresponding relation, so that the weight value accurately reflects the service importance degree of the corresponding user, and then selectively distributing CCE (control channel element) for the uplink user and the downlink user.

The first preset correspondence may be shown in table 3:

TABLE 3 Table 3

Because the uplink and downlink services are different, the embodiment also sets a second preset corresponding relation between the downlink service type and the weight value, and the higher the priority of the downlink service type is, the larger the corresponding weight value is;

and determining a weight value corresponding to the service type of the downlink user as the weight value corresponding to the downlink user based on the second preset corresponding relation, so that the weight value accurately reflects the service importance degree of the corresponding user, and then selectively distributing CCE (control channel element) for the uplink and downlink users.

The second preset correspondence may be shown in table 4:

TABLE 4 Table 4

		Novel RRC control plane data transfer	Y3

New transmission of voice data	Y6
		……	……

Tables 3 and 4 are merely illustrative, and in practice, other service types may be involved, and the service types may correspond to other weight values, etc., which is not specifically limited in this embodiment.

In some optional embodiments, the weight values in the first preset corresponding relationship and the second preset corresponding relationship are both greater than or equal to 1, so as to facilitate subsequent calculation.

In some alternative embodiments, the step S305 may be implemented by, but not limited to, the following ways:

By way of example only, and not by way of limitation, target weighted expected total all_exp_cce_with_weight=ul_all_exp cce_num_with_weight+dl_all_exp_cce_num_wit h_weight; wherein ul_all_exp_cce_num_with_weight is an uplink weighted expected total number, dl_all_exp_cce_num_with_weight is a downlink weighted expected total number;

first uplink proportion ul_cce_ratio=ul_all_exp_cce_num_with_weight/all_exp_cce_with_weight; the ul_all_exp_cce_num_with_weight is the uplink weighting expected total number, and all_exp_cce_with_weight is the target weighting expected total number;

first uplink data Or (F)>

Where FREE CCE NUM is the number of available CCEs, UL CCE RATIO is the first uplink scale,for the rounding up operation, ++>Is a round-down operation.

First downlink quantity dl_cce_num=free_cce_num-ul_cce_num; where FREE CCE NUM is the number of available CCEs and UL CCE NUM is the first uplink number.

determining a ratio between the downlink weighted expected total number and the target weighted expected total number as a first downlink proportion;

performing rounding calculation on the product between the number of the available CCEs and the first downlink proportion to obtain the first downlink number;

and determining the difference between the number of available CCEs and the first downlink number as the first uplink number.

In the implementation, the downlink occupation ratio (the ratio between the downlink weighted expected total number and the target weighted expected total number is determined to be the downlink occupation ratio) can be calculated first; further, the product between the number of available CCEs and the downlink occupation proportion is rounded, so that a first downlink number is obtained; the difference between the number of available CCEs and the first downlink number is determined as the first uplink number, and the specific calculation process may refer to the above embodiment, which is not described herein.

Fig. 4 is a flow chart of a fourth CCE allocation method provided in an embodiment of the present application, where, as shown in fig. 4, the method includes the following steps:

Step S401: and determining the expected CCE number of each uplink user and the expected CCE number of each downlink user in the target TTI.

Step S402: the target CCE number is determined based on a sum of the uplink expected total number and the downlink expected total number.

Step S403: and if the target CCE number is greater than the available CCE number, determining a weight value corresponding to each uplink user and determining a weight value corresponding to each downlink user.

Step S404: based on the weight values corresponding to all uplink users, carrying out weighted calculation on the expected CCE numbers of all uplink users to obtain the uplink weighted expected total number; and carrying out weighted calculation on the expected CCE quantity of all the downlink users based on the weight values corresponding to all the downlink users to obtain the downlink weighted expected total number.

Step S405: and determining a first uplink quantity and a first downlink quantity based on the uplink weighted expected total number, the downlink weighted expected total number and the quantity of the available CCEs.

The specific implementation manner of steps S401 to S405 may refer to the above embodiment, and will not be described herein.

Step S406: a first difference between the uplink weighted expected total and the uplink expected total and a second difference between the downlink weighted expected total and the downlink expected total are determined.

Because the embodiment is based on the uplink weighted expected total number and the downlink weighted expected total number, the influence of the weight is introduced into the determined uplink first downlink number, and sometimes the phenomenon that the CCE allocated by one party exceeds the requirement due to the overlarge influence of the weight, and the CCE may not be allocated enough in the other direction, so that the CCE allocation is unbalanced can occur.

Based on this, the present embodiment determines a first difference between the uplink weighted expected total number and the uplink expected total number, the difference reflecting the influence of the uplink weight; determining a second difference between the downlink weighted expected total and the downlink expected total, the difference reflecting the effect of the weight in the downlink direction;

based on the two differences, it can be determined which weights affect the overweight, so that the allocation restriction is made based on the number of allocations of the weights affecting the overweight party.

Step S407: and if the first difference value is smaller than or equal to the second difference value, distributing CCE to the first target downlink user according to the order of the priority of the service types of the downlink user from high to low.

The number of CCEs allocated to the first target downlink user is smaller than or equal to the first downlink number, and the first target downlink user is a part or all of downlink users.

As described above, the first difference reflects the influence of the weight in the uplink direction, and the second difference reflects the influence of the weight in the downlink direction;

if the first difference is smaller than or equal to the second difference, indicating that the influence of the downlink weight is larger, performing CCE allocation restriction on the downlink direction based on the first downlink quantity, namely, the quantity of CCEs allocated for the downlink user is smaller than or equal to the first downlink quantity.

For example, since the target CCE number is greater than the available CCE number, the available CCEs cannot meet CCE requirements of all uplink and downlink users, and there may be downlink users without CCE resources in the downlink direction;

in order to ensure normal transmission of the service with high priority, the downlink users are ordered from high to low according to the priority of the service types, and CCEs are allocated to the downlink users in order, namely, the downlink users with high priority of the service types are allocated with CCEs first, if the downlink users are not allocated with CCEs, but the number of the CCEs allocated to the downlink users reaches the first downlink number, the CCEs are not allocated to the downlink users with low priority of the service types.

The first target downlink user is a downlink user capable of distributing CCE under the limitation of a first downlink data, and if CCE can be distributed to all downlink users, the first target downlink user is a full downlink user; if CCE cannot be allocated to all downlink users, the first target downlink user is the downlink user with partial service type priority higher.

Step S408: and allocating CCEs to the first target uplink user according to the order of the priority of the service types of the uplink user from high to low.

The first target uplink user is a part or all of the uplink users.

if the first difference is smaller than or equal to the second difference, the influence of the weight in the downlink direction is larger, and the CCE allocation limitation is not performed on the uplink direction, namely, the number of the CCEs allocated for the uplink user can exceed the first uplink number, and after the CCEs are allocated for the downlink user, all the rest CCEs can be allocated for the uplink user.

For example, since the target CCE number is greater than the available CCE number, the available CCEs cannot meet CCE requirements of all uplink and downlink users, and then there may be uplink users without CCE resources in the uplink direction;

In order to ensure normal transmission of the service with high priority, the embodiment sorts the uplink users according to the priority of the service types from high to low, and allocates CCEs to the uplink users according to the order, namely allocates CCEs to the uplink users with high priority of the service types first, and if there are uplink users without CCEs allocated, but no CCE resource exists, does not allocate CCEs to the uplink users with low priority of the service types.

The first target uplink user is an uplink user capable of distributing CCE under the rest CCE quantity, and if CCE can be distributed to all uplink users, the first target uplink user is all uplink users; if CCE cannot be allocated to all uplink users, the first target uplink user is the uplink user with higher priority of partial service types.

Fig. 5 is a flow chart of a fifth CCE allocation method provided in an embodiment of the present application, where, as shown in fig. 5, the method includes the following steps:

step S501: and determining the expected CCE number of each uplink user and the expected CCE number of each downlink user in the target TTI.

Step S502: the target CCE number is determined based on a sum of the uplink expected total number and the downlink expected total number.

Step S503: and if the target CCE number is greater than the available CCE number, determining a weight value corresponding to each uplink user and determining a weight value corresponding to each downlink user.

Step S504: based on the weight values corresponding to all uplink users, carrying out weighted calculation on the expected CCE numbers of all uplink users to obtain the uplink weighted expected total number; and carrying out weighted calculation on the expected CCE quantity of all the downlink users based on the weight values corresponding to all the downlink users to obtain the downlink weighted expected total number.

Step S505: and determining a first uplink quantity and a first downlink quantity based on the uplink weighted expected total number, the downlink weighted expected total number and the quantity of the available CCEs.

Step S506: a first difference between the uplink weighted expected total and the uplink expected total and a second difference between the downlink weighted expected total and the downlink expected total are determined.

The specific implementation manner of steps S501 to S506 may refer to the above embodiment, and will not be described herein.

Step S507: and if the first difference value is larger than the second difference value, distributing CCE to the second target uplink user according to the order of the priority of the service types of the uplink user from high to low.

The number of CCEs allocated to the second target uplink user is smaller than or equal to the first uplink number, and the second target uplink user is a part or all of the uplink users.

if the first difference is greater than the second difference, the uplink weight is larger, and the uplink CCE is allocated and limited based on the first uplink data, namely the number of CCEs allocated for the uplink user is smaller than or equal to the first uplink data.

In order to ensure normal transmission of the service with high priority, the embodiment sorts the uplink users according to the priority of the service types from high to low, and allocates CCEs to the uplink users according to the order, namely allocates CCEs to the uplink users with high priority of the service types first, and if there are uplink users without CCEs allocated to the uplink users, the number of CCEs allocated to the uplink users reaches the first uplink number, then CCEs will not be allocated to the uplink users with low priority of the service types.

The second target uplink user is an uplink user capable of distributing CCE under the limitation of the first uplink number, and if CCE can be distributed to all uplink users, the second target uplink user is all uplink users; if CCE cannot be allocated to all uplink users, the second target uplink user is the uplink user with higher priority of partial service types.

Step S508: and allocating CCE for the second target downlink user according to the order of the priority of the service types of the downlink users from high to low.

Wherein the second target downlink user is a part or all of the downlink users.

If the first difference is larger than the second difference, the influence of the uplink weight is larger, and the downlink CCE allocation is not limited, namely the number of the CCEs allocated for the downlink user can exceed the first downlink number, and after the CCEs are allocated for the uplink user, all the rest CCEs can be allocated for the downlink user.

in order to ensure normal transmission of the service with high priority, the downlink users are ordered from high to low according to the priority of the service types, and CCEs are allocated to the downlink users in order, namely, the downlink users with high priority of the service types are allocated with CCEs first, and if the downlink users have no CCEs and have no CCE resource, the downlink users with low priority of the service types are not allocated with CCEs.

The second target downlink user is a downlink user capable of distributing CCE under the rest CCE quantity, and if CCE can be distributed to all downlink users, the second target downlink user is a full downlink user; if CCE can not be allocated to all downlink users, the second target downlink user is the downlink user with higher priority of partial service type.

Fig. 6 is a flowchart of a sixth CCE allocation method provided in an embodiment of the present application, where, as shown in fig. 6, the method includes the following steps:

step S601: and determining the expected CCE number of each uplink user and the expected CCE number of each downlink user in the target TTI.

Step S602: the target CCE number is determined based on a sum of the uplink expected total number and the downlink expected total number.

Step S603: and if the target CCE number is larger than the available CCE number, determining the ratio between the uplink expected total number and the target CCE number as a second uplink proportion.

If the number of the target CCEs is larger than the number of the available CCEs, the available CCEs cannot meet the CCE requirements of all uplink and downlink users; in this embodiment, regardless of which direction weight has a larger influence, uplink and downlink CCEs are allocated directly according to the ratio of the uplink expected total number to the downlink expected total number;

illustratively, a second uplink proportion, i.e. the proportion of CCEs allocated uplink, is determined according to the ratio between the desired total number of uplink and the target number of CCEs.

Step S604: and carrying out rounding calculation on the product between the number of the available CCEs and the second uplink proportion to obtain a second uplink number.

In this embodiment, after determining the proportion of CCEs allocated in the uplink, the second uplink number, that is, the number of CCEs allocated in the uplink, is determined based on the number of available CCEs.

Step S605: and determining the difference between the number of the available CCEs and the second uplink number as a second downlink number.

In this embodiment, after determining the number of CCEs allocated in the uplink, the second downlink number is further determined based on the number of available CCEs, that is, the number of CCEs allocated in the downlink.

Step S606: and performing CCE allocation based on the second uplink quantity and the second downlink quantity.

In implementation, for the case that the number of target CCEs is greater than the number of available CCEs, in addition to allocating CCEs to uplink and downlink users according to the order of the priority of the service types of the uplink and downlink users from high to low, a priority threshold may be set, and when the number of the allocated CCEs is greater than or equal to the priority threshold, the number of the allocated CCEs is equal to the expected number of CCEs; when the number of CCEs allocated is smaller than the priority threshold, the number of CCEs allocated is smaller than the expected number of CCEs.
