Step 110：The current UE of each PUCCH subsystem based on acquisition number, it is determined that appointing
When the current UE of one PUCCH subsystem of meaning number is more than default threshold value, judge above-mentioned any one
Individual PUCCH subsystems are in higher load condition.
For example：Continue to use the example above, PUCCH subsystems 1, PUCCH subsystems 2 and PUCCH
The predetermined threshold value of system 3 is 10；
PUCCH subsystems 1 are from shared resource pond, the current UE of the PUCCH subsystems 1 of acquisition
Number be 5, the current UE of PUCCH subsystems 2 number is 15, PUCCH subsystems 3
Current UE number is 5；
PUCCH subsystems 1 are according to the current UE of each PUCCH subsystem of acquisition number, really
When the number (15) for determining the current UE of PUCCH subsystems 2 is more than default threshold value (10),
Judge that PUCCH subsystems 2 are in higher load condition.
Step 120：The RB level business and UE currently carried from any one above-mentioned PUCCH subsystem
Selected part business in level business, distribution in addition to any one above-mentioned PUCCH subsystem other are every
One PUCCH subsystem is handled.
Specifically, when performing step 120, it can use but be not limited to following steps：
First, from shared resource pond, the UE that any one above-mentioned PUCCH subsystem is currently carried is obtained
The number and the number of RB grades of business of level business.
Then, the number and UE of the RB level business currently carried from any one above-mentioned PUCCH subsystem
In the number of level business, the number of UE level business to be allocated and the number of RB level business to be allocated are determined
Mesh.
Finally, the principle based on mean allocation, according to above-mentioned UE level business to be allocated number and treat point
The number for the RB level business matched somebody with somebody, the RB level industry that any one above-mentioned PUCCH subsystem is currently carried
Business and UE grade business, distribution extremely in addition to any one above-mentioned PUCCH subsystem other each
PUCCH subsystems carry out corresponding business processing, and (wherein, distribution is part RB grades of service identification and portion
Divide UE grades of service identifications).Wherein, the principle of above-mentioned mean allocation is：Each PUCCH after distribution
The number of the RB level business of subsystem carrying is substantially suitable, and the carrying of each PUCCH subsystem
The number of UE grades of business is substantially suitable.
Further, due to handle UE grades of business when, it is necessary to use the processing of corresponding RB grades of business
As a result, so, in order to ensure handle each UE grades of business when, can get corresponding RB
The result of level business, it is determined that receiving the RB level business that the distribution of other PUCCH subsystems comes
, it is necessary to first be sequentially completed distribution to the processing of local RB level business during with UE grades of business, and will processing
The results of all RB grades of business preserve to shared resource pond, then it is determined that each PUCCH is sub
When system completes the processing of all RB level business, distribution is sequentially completed to local UE level business
Processing, and ACK and CQI in corresponding UE grades of service processing result is reported into corresponding cell respectively
High level.Wherein, each PUCCH subsystem of above-mentioned determination completes the place of all RB level business
During reason, it can use but be not limited in the following manner：It is determined that each PUCCH being stored in shared resource pond
When the flag bit of subsystem puts 1, judge that each PUCCH subsystem completes all RB level industry
The processing of business.
Preferably, in order to ensure the current RB level business of itself do not postpone, it is necessary to first processing currently itself
RB grades of business, it is determined that when the current RB levels business processing of itself is completed, then other PUCCH are handled successively
Subsystem is distributed to local RB level business.
Specifically, the RB level business that the distribution of other PUCCH subsystems comes is handled successively, and will processing
The result of all RB grades of business when preserving to shared resource pond, can use but be not limited to following step
Suddenly：
First, the RB level service identifications carried in each RB grades of business come based on distribution, successively
Corresponding RB grades of service parameter is obtained from above-mentioned shared resource pond.
Then, each RB grades of service parameter based on acquisition, completes the processing of corresponding RB grades of business.
Finally, each RB grades of service identification is corresponded to respectively, and corresponding RB grades of service processing result is protected
Deposit to above-mentioned shared resource pond, wherein, above-mentioned RB grades of service processing result can be but not limited to：Despreading
As a result.
Preferably, in order to ensure handle each UE grades of business when, can from shared resource pond,
The result of corresponding RB grades of business is got, it is necessary to it is determined that each PUCCH subsystem is complete
Into after the processing of all RB level business, then UE grades of business are handled successively.
Preferably, in order to ensure the current UE level business of itself do not postpone, it is necessary to first processing currently itself
UE grades of business, it is determined that when the current UE levels business processing of itself is completed, then other PUCCH are handled successively
Subsystem is distributed to local UE level business.
Specifically, processing is distributed to local UE level business successively, and respectively by corresponding UE grades of industry
ACK and CQI is when reporting to the high level of corresponding cell in business result, can use but be not limited to
Lower step：
First, the UE level service identifications carried in each UE grades of business come based on distribution, according to
The mapping relations of default UE grades of service identification and RB grades of service identifications, successively from above-mentioned shared resource pond
In, the corresponding RB grades of service processing result of corresponding RB grades of service identification is obtained, and obtain corresponding
UE grades of service parameters.
Then, each RB grades of service processing result and corresponding UE grades of business ginseng of acquisition are based respectively on
Number, completes the processing of corresponding UE grades of business.
Finally, based on the cell ID carried in each UE grades of business, respectively by corresponding UE grades of industry
ACK and CQI in business result report to the high level of corresponding cell.
For example：Continue to use the example above, PUCCH subsystems 1 determine PUCCH subsystems 2 in high negative
After lotus state, from shared resource pond, the UE that each the PUCCH subsystem got is currently carried
The level number of business and the number of RB grades of business are respectively：
The number for the RB level business that PUCCH subsystems 1 are currently carried is 10, the UE currently carried
The number of level business is 15；
The number for the RB level business that PUCCH subsystems 2 are currently carried is 25 (corresponding RB grades of industry
Business is designated 1-RB grades of business 25 of RB grades of business), the number of the UE level business currently carried is 45
Individual (corresponding UE grades of service identification is 1-UE grades of business 45 of UE grades of business)；
The number for the RB level business that PUCCH subsystems 3 are currently carried is 10, the UE currently carried
The number of level business is 15.
PUCCH subsystems 1 determine that the number of RB level business to be allocated is (corresponding RB grades for 10
Service identification is 16-RB grades of business 25 of RB grades of business), and the number of UE level business to be allocated is
20 (corresponding UE grades of service identification is 26-UE grades of business 45 of UE grades of business).
Principle of the PUCCH subsystems 1 based on mean allocation, by 10 RB level traffic assignments to be allocated
5 are given itself, (i.e. by corresponding RB grades of service identification：16-RB grades of business 20 of RB grades of business, point
Dispensing itself), PUCCH subsystems 3 are given in distribution 5, (i.e. by corresponding RB grades of service identification：RB
Level 21-RB grades of business 25 of business, distribute to PUCCH subsystems 3) so that each PUCCH
The number for the RB level business that system is currently carried is identical (being 15), and by 20 UE to be allocated
Level traffic assignments 10 are to itself (i.e. by corresponding UE grades of service identification：UE grades of 26-UE grades of business
Business 35 distributes to itself), distribution 10 is to PUCCH subsystems 3 (i.e. by corresponding UE grades of business
Mark：36-UE grades of business 45 of UE grades of business distribute to PUCCH subsystems 3) so that each
The number for the UE level business that PUCCH subsystems are currently carried is identical (being 20).
Because RB grades of business of each subsystem processes are identical with the method for UE grades of business, below only with
Illustrated exemplified by PUCCH subsystems 1.
PUCCH subsystems 1 are come after the processing of the current RB level business of itself is completed based on distribution
Each RB grades of service identification (16-RB grades of business 20 of RB grades of business), successively from shared resource pond
It is middle to obtain corresponding RB grades of service parameter, and each RB grades of service parameter based on acquisition, complete phase
The processing for the RB level business answered, and each RB grades of service identification (RB grades of business 16 are corresponded to respectively
- RB grades of business 20), corresponding RB grades of business despread result is preserved to shared resource pond and (now, will
1) flag bit 1 for the PUCCH subsystems 1 being stored in shared resource pond is put.
PUCCH subsystems 1 determine to be stored in the flag bit 1 of PUCCH subsystems 1 in shared resource pond,
After the flag bit 2 of PUCCH subsystems 2 and the flag bit 3 of PUCCH subsystems 3 put 1, continue
The current UE level business of itself of processing, it is determined that completing after the currently processing of the UE level business of itself, is based on
Each UE grades of service identification (26-UE grades of business 35 of UE grades of business) come is distributed, successively from altogether
Enjoy and corresponding despread result is obtained in resource pool, and UE grades of service parameters, and each based on acquisition
UE grades of service parameters and corresponding result, complete the processing of corresponding UE grades of business, and correspondingly
Cell ID 2 (corresponding cell is cell 2), respectively by the ACK in corresponding UE grades of service processing result
The high level of cell 2 is reported to CQI.Wherein, PUCCH subsystems 1 (corresponding cell is cell 1)
, also can be by the ACK in corresponding UE grades of service processing result after the processing for completing the UE level business of itself
The high level of cell 1 is reported to CQI.
