Description

Method and device for CCE resource allocation in communication system

This application claims the national priority of the Chinese patent application with application number 201110024464.2 right.

technical field

The present invention relates to the communication field, in particular to a method and equipment for CCE resource allocation in a communication system.

Background technique

The control channel element (CCE) of the physical downlink control channel (PDCCH) is a resource used for uplink and downlink. When a user equipment (UE) is scheduled for downlink or uplink, the system must allocate CCE resources for it, and in this The data of the PDCCH is transmitted on the CCE resource. Once the CCE resource is occupied by a certain UE, other UEs cannot use it.

At present, most systems use static uplink/downlink CCE resource allocation, and use a first-come-first-served (FCFS) algorithm to solve the problem of CCE conflicts. The most direct solution to the PDCCH dynamic allocation algorithm is to calculate the UE-specific search space, and allocate CCEs to the UE-specific search space first in a first-come-first-served strategy, otherwise, in the case of conflicts, allocate CCEs to the common search space.

Specifically, for the FCFS algorithm, it calculates the UE-specific search space according to the predetermined aggregation level of the user equipment (determined based on the TLA2.1 algorithm). If there are still some positions available within this UE-specific search space, a simple solution is taken: ie, choose by the highest CCE index. The same procedure also applies to the common search space if there is no location available within the UE-specific search space. Finally, if the common search space has also been fully allocated, the UE will not be allocated any CCE resources, and then proceeds to process the next user equipment.

Figure 1 shows a diagram of the result of allocating PDCCH CCEs according to the FCFS algorithm. The shown system bandwidth is 20MHz, CFI=1, the total number of CCE resources in subframe 0 is 21, and a total of 6 UEs need to be scheduled. Using the FCFS algorithm, UE3 and UE6 are blocked, so the utilization rate of CCE resources is 33.3%, and the scheduling rate of UE is 66.7%. The utilization rate of CCE resources is not ideal.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

Fig. 2 shows a flowchart of a method for CCE resource allocation in a communication system according to one aspect of the present invention. Wherein, the communication system includes: k user equipments, for example, user equipment 11, user equipment 12, ... user equipment 1k; and a resource allocation device. The communication system includes but is not limited to: an LTE system and the like.

Specifically, in step S01, the resource allocation device determines a predetermined number of multiple user equipments to be allocated to which CCE resources need to be allocated based on the priority of each user equipment. For example, the priority of user equipment 11 is 1; the priority of user equipment 12 is 1.5; ... the priority of user equipment 1k is 1.8, thus, the resource allocation device is based on user equipment 11, user equipment 12, ...the priority of the user equipment 1k, select a predetermined number of them, for example, i, the user equipment with the highest priority as the user equipment to be allocated, for example, respectively recorded as: UE1, UE2.... .. UEi.

Next, in step S02 , the resource allocation device marks each available CCE resource of each user equipment to be allocated based on the respective user radio network identifier (C-RNTI) and aggregation level of the plurality of user equipments to be allocated. For example, the physical downlink control channel (PDCCH) of the communication system has 21 CCE resources for allocation, represented by CCE0 to CCE20 respectively, so that the resource allocation device is based on the C-RNTI and aggregation level of the user equipment UE1 to be allocated (that is, AL), for example, is 2, marking the CCE resources available to the user equipment UE1, for example, starting from CCE2 to the end of CCE13; for another example, the resource allocation device is based on the C-RNTI and aggregation level of the user equipment UE2 to be allocated, For example, it is 4, marking the CCE resources available to the user equipment UE2, for example, starting from CCE2 to ending with CCE9.

Next, in step S03, the resource allocation device calculates the allocation of CCE resources available to each user equipment to be allocated to CCE resources available to other user equipment to be allocated based on the respective available CCE resources, aggregation level and priority of each user equipment to be allocated degree of influence. For example, based on the CCE resources available to the user equipment UE1, for example, from CCE2 to CCE13, the aggregation level, such as 2, and the priority, the resource allocation device calculates if it occupies CCE2 and CCE3, it is available to other user equipment to be allocated. The impact degree of CCE resource allocation is 14. If it occupies CCE4 and CCE5, the impact degree of CCE resource allocation available to other user equipments to be allocated is 13. If it occupies CCE12 and CCE13, it will affect other user equipments to be allocated. Available CCE resource allocations are affected by a degree of 13 and so on.

Next, in step S04, the resource allocation device allocates CCE resources one by one for the plurality of user equipments to be allocated based on the degree of influence and priority. For example, among the user equipments UE1, UE2...UEi to be allocated, the user equipment UE1 has the highest priority, then the resource allocation device first assigns other user equipment UE2. . . . The degree of influence of UEi, among its available CCE resources, allocate the CCE resource with the least degree of influence to UE1, for example, CCE10 and CCE11. Next, arrange the second user equipment to be allocated in descending order of priority, for example: user equipment UE2, then the resource allocation device first bases on the calculated CCE resources available to user equipment UE2 (for example, CCE8 to CCE15) to other The degree of influence of user equipment UE1, UE3...UEi, allocate CCE resources with the least degree of influence to user equipment UE2, such as: CCE8 and CCE9, so that CCEs are allocated to i user equipment to be allocated one by one based on priority resource.

Fig. 3 shows a flowchart of a method for CCE resource allocation in a communication system according to another aspect of the present invention.

Specifically, in step S01', the resource allocation device determines a predetermined number of multiple user equipments to be allocated that need to be allocated CCE resources based on the priority of each user equipment. For example, based on the priorities of user equipment 11, user equipment 12, ... user equipment 1k, the resource allocation device selects a predetermined number, for example, 6, user equipment with the highest priority as user equipment to be allocated , for example, respectively denoted as: UE1, UE2, UE3, UE4, UE5, UE6.

Next, in step S02', the resource allocation device arranges the CCE resources in the horizontal direction, arranges the user equipments to be allocated in the vertical direction according to the priority, and based on the respective C-RNTI and The aggregation level marks each available CCE resource of each user equipment to be allocated to form a CCE resource marking matrix. For example, the physical downlink control channel (PDCCH) of the communication system has 21 CCE resources, respectively marked as CCE0, CCE1, ... CCE20; the aggregation level _AL1 of the user equipment UE1 to be allocated is 2, and the resources The allocation device marks its available CCE resources based on the C-RNTI and aggregation level of the user equipment UE1, for example: CCE4 to CCE15; the aggregation level AL ₂ of the user equipment UE2 to be allocated is 2, and the resource allocation device is based on the C-RNTI of the user equipment UE2. - RNTI and aggregation level mark its available CCE resources, for example: CCE6 to CCE17; the aggregation level AL ₃ of the user equipment UE3 to be allocated is 4, and the resource allocation device marks its availability based on the C-RNTI and aggregation level of the user equipment UE3 CCE resources, for example: CCE2 to CCE9; the aggregation level AL ₄ of the user equipment UE4 to be allocated is 2, and the resource allocation device marks its available CCE resources based on the C-RNTI and aggregation level of the user equipment UE4, for example: CCE8 to CCE19; the aggregation level AL ₅ of the user equipment UE5 to be allocated is 1, and the resource allocation equipment marks its available CCE resources based on the C-RNTI and aggregation level of the user equipment UE5, for example: CCE12 to CCE17; the user equipment to be allocated The aggregation level _AL6 of UE6 is 4, and the resource allocation device marks its available CCE resources based on the C-RNTI and aggregation level of UE6, for example: CCE6 to CCE13, thus, the formed CCE resource marking matrix is shown in Figure 4 Show.

Next, in step S031, the resource allocation device calculates the intermediate value BULB_aux _i,j based on the CCE resource marking matrix according to the following formula:

BULB_aux _{i, j} = w(AL _i ) · AL _{i, j} · (row _max -i+1) (1)

Wherein, i is the row index in the CCE resource marking matrix,

j is the column index in the CCE resource tag matrix,

AL _{i, j} is the tag value of row i and column j in the CCE resource tag matrix,

w(AL _i ) is the first predetermined weight factor of the user equipment arranged in the i-th row,

row _max is the maximum row index.

As a preferred manner, the first predetermined weight factor w(AL _i ) is inversely proportional to the aggregation level AL _i of the user equipment in the i-th row. For example, for user equipment UE1, its aggregation level AL _i =2, the first predetermined weight factor w(AL ₁ ), for example: 0.6, for user equipment UE3, its aggregation level AL _i =4, the first predetermined weight factor w (AL ₃ ), for example: 0.4, for user equipment UE5, its aggregation level AL _i =1, the first predetermined weight factor w(AL ₅ ), for example: 1; in addition, if there is a user equipment with an aggregation level of 8 , its first predetermined weight factor is, for example, 0.2. Therefore, the resource allocation device calculates the intermediate value of the available CCE resource CCE4 of the user equipment UE1 according to the formula (1) based on the CCE resource marking matrix:

BUBL_aux _1,4 = w(AL _i )·AL _1,4 ·(6−1+1)=0.6*2*6=7.2.

For another example, for the user equipment UE3, the resource allocation device calculates the median value of its available CCE resource CCE2 according to the formula (1) based on the CCE resource marking matrix:

BUBL_aux _3,4 = w(AL ₃ )·AL _3,4 ·(6−3+1)=0.4·4·4=6.4.

Similarly, the resource allocation device can calculate the respective intermediate values of the available CCE resources CCE5 to CCE15 of the user equipment UE1, and the respective intermediate values of the available CCE resources of the user equipment UE2 to UE6. The intermediate values are shown in FIG. Explain one by one.

Next, in step S032, the resource allocation device calculates the degree of influence of the CCE resources available to each user equipment to be allocated on the CCE resources available to other user equipments to be allocated based on the intermediate values according to the following formula:

${\mathrm{<span\; class="notranslate">\; BULB</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; j</span>}}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; BULB</span>}<span\; class="notranslate">\; \_</span>{\mathrm{<span\; class="notranslate">\; aux</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; j</span>}}$

Wherein, w_up is a second predetermined weight factor, for example, 0.1.

For example, the resource allocation device calculates the degree of influence of the CCE resource CCE4 on the respective available CCE resources of the user equipment UE2 to UE6 based on the median value of the available CCE resource CCE4 of the user equipment UE1 according to formula (2):

BULB _1,4 = BULB_aux _1,4

+max(BULB_aux _{2, 4} , BULB_aux _{3, 4} , .., BULB_aux _{6, 4} )

＝ 7.2+6.4

= 13.6

Based on the same method as above, the resource allocation device can calculate one by one the degree of influence of the available CCE resources CCE5 to CCE15 of the user equipment UE1 on the respective available CCE resources of the user equipment UE2 to UE6, and the impact of the available CCE resources of the user equipment UE2 to UE6 on other CCE resources. The influence degrees of the available CCE resources of the user equipment are shown in FIG. 6 , and will not be described one by one here.

Next, in step S033, the resource allocation device calculates the average value of the influence degree of the CCE resource group available to each user equipment based on the aggregation level and the degree of influence according to the following formula:

$\mathrm{<span\; class="notranslate">\; BULB</span>}<span\; class="notranslate">\; \_</span>{\mathrm{<span\; class="notranslate">\; mean</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; j</span>}}^{\mathrm{<span\; class="notranslate">\; l</span>}}<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; AL</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; =</span>\frac{\underset{\mathrm{<span\; class="notranslate">\; j</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; start</span>}<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; AL</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; l</span>}<span\; class="notranslate">\; )</span>}{\overset{\mathrm{<span\; class="notranslate">\; end</span>}<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; AL</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; l</span>}<span\; class="notranslate">\; )</span>}{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}}{\mathrm{<span\; class="notranslate">\; BULE</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; j</span>}}}{\mathrm{<span\; class="notranslate">\; end</span>}<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; AL</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; l</span>}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; start</span>}<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; AL</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; l</span>}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; +</span>\mathrm{<span\; class="notranslate">\; 1</span>}}<span\; class="notranslate">\; ,</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 3</span>}<span\; class="notranslate">\; )</span>$

Among them, start(AL _i , l) is the starting position of the CCE resource in the lth CCE resource group available to the user equipment arranged in the i-th row, and end(AL _i , l) is available to the user equipment arranged in the i-th row The end position of the CCE resource in the lth CCE resource group of .

For example, the resource allocation device calculates the average influence degree of CCE resource group 1 (that is, CCE2 to CCE5) based on the aggregation level and influence degree of the user equipment UE3 according to formula (3):

$\mathrm{BUBl}\_{\mathrm{mean}}_{\mathrm{3,4}}^l\left({\mathrm{AL}}_3\right)=\frac{\underset{j=\mathrm{start}({\mathrm{AL}}_3,l)}{\overset{\mathrm{end}({\mathrm{AL}}_3,l)}{\mathrm{\&Sigma;}}}{\mathrm{BUBL}}_{3,j}}{\mathrm{end}({\mathrm{AL}}_3,l)-\mathrm{start}({\mathrm{AL}}_3,l)+1}=\frac{\underset{j=2}{\overset{j=5}{\mathrm{\&Sigma;}}}{\mathrm{BULB}}_{3,j}}{5-2+1}=6.05;$ Based on the same method as above, the resource allocation device can calculate the average influence degree of the CCE resource group 2 (that is, CCE6 to CCE9) of the user equipment UE3, and the influence degrees of the respective CCE resource groups of the user equipment UE1, UE2, UE4 to UE6 The average value and the average value of each degree of influence are specifically shown in Figure 7, and will not be described in detail here.

Next, in step S04', the resource allocation device allocates CCE resources one by one for the plurality of user equipments to be allocated based on the average value of influence degree and priority. For example, the resource allocation device sequentially allocates CCE resources for user equipment UE1, user equipment UE2, user equipment UE3, user equipment UE4, user equipment UE5, and user equipment UE6 based on priorities. Among them, for the user equipment UE1, the resource allocation device selects the available CCE resources from the one with the smallest average value of the influence degree, for example: CCE10-CCE11; for the user equipment UE2, the resource allocation device selects the available CCE resources from the one with the smallest average value The available CCE resources are, for example: CCE12-CCE13; for the user equipment UE3, the resource allocation device selects the available CCE resources from the one with the smallest average influence degree, for example: CCE2-CCE5; for the user equipment UE4, the resource allocation device Select the available CCE resource from the one with the smallest average value of its influence degree, for example: CCE18-CCE19; for the user equipment UE5, the resource allocation device selects the available CCE resource from the one with the smallest average value of its influence degree, for example: CCE16 ; For user equipment UE6, the resource allocation device selects available CCE resources from the one with the smallest average value of influence degree, for example: CCE6-CCE9; CCE resource allocation is shown in FIG. 8 . Apparently, among the 21 CCE resources for allocation of PDCCH, 15 of them are allocated to user equipments UE1 to UE6, the allocation rate of CCE resources of PDCCH is as high as 71.4%, and all 6 user equipments to be allocated have obtained CCE resources. The CCE resource scheduling rate of the device is as high as 100%.

FIG. 9 shows a schematic diagram of a device for CCE resource allocation in a communication system according to one aspect of the present invention. Wherein, the resource allocation device includes: determining means 11 , marking means 12 , calculating means 13 , and allocating means 14 .

Specifically, the determining module 11 determines a predetermined number of multiple user equipments to be allocated that need to be allocated CCE resources based on the priority of each user equipment. For example, the priority of user equipment 11 is 1; the priority of user equipment 12 is 1.5; ... the priority of user equipment 1k is 1.8, thus, the determining means 11 is based on user equipment 11, user equipment 12, ...the priority of the user equipment 1k, select a predetermined number of them, for example, i, the user equipment with the highest priority as the user equipment to be allocated, for example, respectively recorded as: UE1, UE2.... .. UEi.

Next, the marking means 12 marks the respective available CCE resources of each of the user equipments to be allocated based on the respective user radio network identifiers (C-RNTIs) and aggregation levels of the plurality of user equipments to be allocated. For example, the physical downlink control channel (PDCCH) of the communication system has 21 CCE resources available for allocation, which are represented by CCE0 to CCE20 respectively. Therefore, the marking device 12 is based on the C-RNTI and aggregation level of the user equipment UE1 to be allocated (that is, AL), for example, is 2, marking the CCE resources available to the user equipment UE1, for example, starting from CCE2 to the end of CCE13; for another example, the marking device 12 is based on the C-RNTI and aggregation level of the user equipment UE2 to be allocated, For example, it is 4, marking the CCE resources available to the user equipment UE2, for example, starting from CCE2 to ending with CCE9.

Next, the calculating means 13 calculates the influence degree of the CCE resources available for each user equipment to be allocated on the allocation of CCE resources available to other user equipments to be allocated based on the respective available CCE resources, aggregation level and priority of each user equipment to be allocated. For example, based on the CCE resources available to the user equipment UE1, for example, from CCE2 to CCE13, the aggregation level, for example, 2, and the priority, the calculation means 13 calculates if it occupies CCE2 and CCE3, it is available to other user equipment to be allocated The degree of influence of CCE resource allocation is 14. If it occupies CCE4 and CCE5, the degree of influence on the allocation of CCE resources available to other user equipments to be allocated is 13. If it occupies CCE12 and CCE13, it will affect other user equipments to be allocated. Available CCE resource allocations are affected by a degree of 13 and so on.

Next, the allocating module 14 allocates CCE resources to the plurality of user equipments to be allocated one by one based on the degree of influence and the priority. For example, among the user equipments UE1, UE2... UEi to be allocated, the priority of the user equipment UE1 is the highest, then the allocating means 14 first assigns other user equipment UE2. . . . The degree of influence of UEi, among its available CCE resources, allocate the CCE resource with the least degree of influence to UE1, for example, CCE10 and CCE11. Next, arrange the second user equipment to be allocated in descending order of priority, for example: user equipment UE2, then the allocating means 14 first bases on the calculated CCE resources available to user equipment UE2 (for example, CCE8 to CCE15) to other The degree of influence of user equipment UE1, UE3...UEi, allocate CCE resources with the least degree of influence to user equipment UE2, such as: CCE8 and CCE9, so that CCEs are allocated to i user equipment to be allocated one by one based on priority resource.

Fig. 10 shows a schematic diagram of a device for CCE resource allocation in a communication system according to another aspect of the present invention. Wherein, the resource allocation device includes: determining means 11 , marking means 12 , calculating means 13 , and allocating means 14 ;

Specifically, the determining module 11 determines a predetermined number of multiple user equipments to be allocated that need to be allocated CCE resources based on the priority of each user equipment. For example, based on the priorities of user equipment 11, user equipment 12, ... user equipment 1k, determining means 11 selects a predetermined number of them, for example, 6 user equipments with the highest priority as the user equipment to be allocated , for example, respectively denoted as: UE1, UE2, UE3, UE4, UE5, UE6.

Next, the marking unit 12 arranges the CCE resources in the horizontal direction, arranges the user equipments to be allocated in the vertical direction according to the priority, and marks each of the multiple user equipments to be allocated based on the respective C-RNTI and aggregation level of the multiple user equipments to be allocated. CCE resources available to user equipments are allocated to form a CCE resource marking matrix. For example, the physical downlink control channel (PDCCH) of the communication system has 21 CCE resources, respectively marked as CCE0, CCE1, ... CCE20; the aggregation level _AL1 of the user equipment UE1 to be allocated is 2, marked Apparatus 12 marks available CCE resources based on the C-RNTI and aggregation level of user equipment UE1, for example: CCE4 to CCE15; the aggregation level AL ₂ of user equipment UE2 to be allocated is 2, and marking means 12 is based on the C-RNTI of user equipment UE2. - RNTI and aggregation level mark its available CCE resources, for example: CCE6 to CCE17; the aggregation level AL ₃ of the user equipment UE3 to be allocated is 4, and the marking device 12 marks its availability based on the C-RNTI and aggregation level of the user equipment UE3 CCE resources, for example: CCE2 to CCE9; the aggregation level AL4 of the user equipment UE4 to be allocated is ₂ , and the marking means 12 marks the available CCE resources based on the C-RNTI and aggregation level of the user equipment UE4, for example: CCE8 to CCE19; the aggregation level _AL5 of the user equipment UE5 to be allocated is 1, and the marking device 12 marks its available CCE resources based on the C-RNTI and the aggregation level of the user equipment UE5, for example: CCE12 to CCE17; the user equipment to be allocated The aggregation level _AL6 of UE6 is 4, and the marking device 12 marks its available CCE resources based on the C-RNTI and aggregation level of the user equipment UE6, for example: CCE6 to CCE13, thus, the formed CCE resource marking matrix is shown in Figure 4 Show.

Next, the first calculation unit 131 calculates the intermediate value BULB_aux _i,j based on the CCE resource label matrix according to the following formula:

BULB_aux _{i, j} = w(AL _i ) · AL _{i, j} · (row _max -i+1) (1)

Wherein, i is the row index in the CCE resource marking matrix,

j is the column index in the CCE resource tag matrix,

AL _{i, j} is the tag value of row i and column j in the CCE resource tag matrix,

w(AL _i ) is the first predetermined weight factor of the user equipment arranged in the i-th row,

row _max is the maximum row index.

As a preferred manner, the first predetermined weight factor w(AL _i ) is inversely proportional to the aggregation level AL _i of the user equipment in the i-th row. For example, for user equipment UE1, its aggregation level AL _i =2, the first predetermined weight factor w(AL ₁ ), for example: 0.6, for user equipment UE3, its aggregation level AL _i =4, the first predetermined weight factor w (AL ₃ ), for example: 0.4, for user equipment UE5, its aggregation level AL _i =1, the first predetermined weight factor w(AL ₅ ), for example: 1; in addition, if the aggregation level of a user equipment is 8 , its first predetermined weight factor is, for example, 0.2. Therefore, the first calculation unit 131 calculates the median value of the available CCE resource CCE4 of the user equipment UE1 according to the formula (1) based on the CCE resource marking matrix:

BULB_aux _1,4 = w(AL ₁ )·AL _1,4 ·(6-1+1)

=0.6*2*6;

=7.2

Similarly, the first calculation unit 131 can calculate the respective intermediate values of the available CCE resources CCE5 to CCE15 of the user equipment UE1, and the respective intermediate values of the available CCE resources of the user equipment UE2 to UE6. The intermediate values are shown in FIG. 5, where I won't explain them one by one.

Next, the second calculation unit 132 calculates the degree of influence of the CCE resources available to each user equipment to be allocated on the CCE resources available to other user equipment to be allocated based on the intermediate values according to the following formula:

${\mathrm{<span\; class="notranslate">\; BULB</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; j</span>}}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; BULB</span>}<span\; class="notranslate">\; \_</span>{\mathrm{<span\; class="notranslate">\; aux</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; j</span>}}$

Wherein, w_up is a second predetermined weight factor, for example, 0.1.

For example, the second calculation unit 132 calculates the degree of influence of the CCE resource CCE4 on the respective available CCE resources of the user equipment UE2 to UE6 based on the median value of the CCE resource CCE4 available to the user equipment UE1 according to formula (2):

BULB _{1, 4} = BULB_aux _{1, 4}

+max(BULB_aux _{2, 4} BULB_aux _{3, 4} , ..BULB_aux _{6, 4} ),

＝7.2+6.4

=13.6

Based on the same method as above, the second calculation unit 132 can calculate the degree of influence of the available CCE resources CCE5 to CCE15 of the user equipment UE1 on the respective available CCE resources of the user equipment UE2 to UE6, and the respective available CCE resources of the user equipment UE2 to UE6 The degree of impact of the resources on the available CCE resources of other user equipments is shown in FIG. 6 , and will not be described here one by one.

Next, the third calculation unit 133 calculates the average value of the influence degree of the CCE resource group available to each user equipment based on the aggregation level and the influence degree according to the following formula:

$\mathrm{<span\; class="notranslate">\; BULB</span>}<span\; class="notranslate">\; \_</span>{\mathrm{<span\; class="notranslate">\; mean</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; j</span>}}^{\mathrm{<span\; class="notranslate">\; l</span>}}<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; AL</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; =</span>\frac{\underset{\mathrm{<span\; class="notranslate">\; j</span>}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; start</span>}<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; AL</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; l</span>}<span\; class="notranslate">\; )</span>}{\overset{\mathrm{<span\; class="notranslate">\; end</span>}<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; AL</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; l</span>}<span\; class="notranslate">\; )</span>}{\mathrm{<span\; class="notranslate">\; \&Sigma;</span>}}}{\mathrm{<span\; class="notranslate">\; BULE</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; j</span>}}}{\mathrm{<span\; class="notranslate">\; end</span>}<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; AL</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; l</span>}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; start</span>}<span\; class="notranslate">\; (</span>{\mathrm{<span\; class="notranslate">\; AL</span>}}_{\mathrm{<span\; class="notranslate">\; i</span>}}<span\; class="notranslate">\; ,</span>\mathrm{<span\; class="notranslate">\; l</span>}<span\; class="notranslate">\; )</span><span\; class="notranslate">\; +</span>\mathrm{<span\; class="notranslate">\; 1</span>}}<span\; class="notranslate">\; ,</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; -</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 3</span>}<span\; class="notranslate">\; )</span>$

Among them, start(AL _i , l) is the starting position of the CCE resource in the lth CCE resource group available to the user equipment arranged in the i-th row, and end(AL _i , l) is available to the user equipment arranged in the i-th row The end position of the CCE resource in the lth CCE resource group of .

For example, the third calculation unit 133 calculates the average value of the influence degree of CCE resource group 1 (that is, CCE2 to CCE5) based on the aggregation level and influence degree of the user equipment UE3 according to formula (3):

$\mathrm{BUBl}\_{\mathrm{mean}}_{\mathrm{3,4}}^l\left({\mathrm{AL}}_3\right)=\frac{\underset{j=\mathrm{start}({\mathrm{AL}}_3,l)}{\overset{\mathrm{end}({\mathrm{AL}}_3,l)}{\mathrm{\&Sigma;}}}{\mathrm{BUBL}}_{3,j}}{\mathrm{end}({\mathrm{AL}}_3,l)-\mathrm{start}({\mathrm{AL}}_3,l)+1}=\frac{\underset{j=2}{\overset{j=5}{\mathrm{\&Sigma;}}}{\mathrm{BULB}}_{3,j}}{5-2+1}=6.05;$ The third calculation unit 133 can calculate the average influence degree of the user equipment UE3 CCE resource group 2 (that is, CCE6 to CCE9) and the influence degree of the respective CCE resource groups of the user equipment UE1, UE2, UE4 to UE6 based on the same method as above The average value and the average value of each degree of influence are specifically shown in Figure 7, and will not be described in detail here.

Next, the allocating module 14 allocates CCE resources to the plurality of user equipments to be allocated one by one based on the average value of the influence degree and the priority. For example, the allocating means 14 sequentially allocates CCE resources for user equipment UE1, user equipment UE2, user equipment UE3, user equipment UE4, user equipment UE5, and user equipment UE6 based on priorities. Among them, for the user equipment UE1, the allocating means 14 selects the available CCE resources from the one with the smallest average value of the degree of influence, for example: CCE10-CCE11; for the user equipment UE2, the allocator 14 selects the resource from the one with the smallest average value The available CCE resources are, for example: CCE12-CCE13; for the user equipment UE3, the allocation means 14 selects the available CCE resources from the one with the smallest average influence degree, such as: CCE2-CCE5; for the user equipment UE4, the allocation means 14 Select the available CCE resource from the one with the smallest average value of its influence degree, for example: CCE18-CCE19; for the user equipment UE5, the allocation means 14 selects the available CCE resource from the one with the smallest average value of its influence degree, for example: CCE16 ; For the user equipment UE6, the allocating means 14 selects the available CCE resource from the one with the smallest average influence degree, for example: CCE6-CCE9; CCE resource allocation is shown in FIG. 8 . Apparently, among the 21 allocated CCE resources of PDCCH, 15 of them are allocated to user equipments UE1 to UE6, the allocation rate of CCE resources of PDCCH is as high as 71.4%, and all 6 user equipments to be allocated have obtained CCE resources. The CCE resource scheduling rate of the device is as high as 100%.
