Content, so will not be described in detail herein.
The number of second radio frames can be one, or multiple, number of the embodiment of the present invention to the second radio frames
Amount is not particularly limited.Situation when wherein the number of the second radio frames is one includes：At least one second radio frames is the
A upper radio frames for one radio frames, at least one second radio frames be the first radio frames before at least two radio frames the
The most radio frames of CCE numbers in one subframe needed for failed scheduling user, at least one second radio frames is first wireless
Scheduling needs to be dispatched user's still scarce CCE numbers at most wireless in first subframe of at least two radio frames before frame
Frame, etc..
It is used for the Physical Downlink Control Channel for transmitting user-specific information in first subframe of at least one the second radio frames
PDCCH control channel unit CCE usage records include：First subframe of each radio frames at least one second radio frames
In the middle CCE numbers used in successful dispatch user, at least one second radio frames in the first subframe of each radio frames
Dispatched in CCE numbers needed for failed scheduling user, at least one second radio frames in the first subframe of each radio frames
Need to be dispatched in user's still scarce CCE numbers, at least one second radio frames in the first subframe of each radio frames not into
Number of work(scheduling user, etc., the embodiment of the present invention is not particularly limited.
Step 120：According in first subframe of the CCE usage records and first radio frames be for sending out
The CCE numbers that the PDCCH of common control information is distributed are sent, determine to be used to send out in first subframe of first radio frames
Send the CCE total numbers needed for PDCCH.
Wherein, step 120 can include：Step 121, step 122 and step 123.
Step 121：It is determined that being for sending user-specific information in first subframe of the first current radio frames
CCE numbers required for PDCCH.
According to the physical downlink control channel PDCCH for being used to transmit user-specific information in the first subframe of the second radio frames
Control channel unit CCE usage records, it is determined that being for sending user in first subframe of the first current radio frames
CCE numbers required for the PDCCH of proprietary information.Wherein, the quantity of the second radio frames is different, it is determined that the first current radio frames
The first subframe in CCE numbers required for PDCCH for sending user-specific information method it is different.
It is for sending user-specific letter in the first subframe of the first radio frames when the quantity of the second radio frames is one
CCE numbers required for the PDCCH of breath are：
NCCEest=NCCEfail+NCCEspec；
Wherein, NCCEspecFor in the first subframe of the second radio frames used in successful dispatch user CCE numbers；
NCCEfailFor the CCE numbers or the first of the second radio frames needed for failed scheduling user in the first subframe of the second radio frames
Scheduling needs to be dispatched in user's still scarce CCE numbers, the first subframe of the second radio frames in subframe dispatches user institute not successfully
The CCE numbers needed with dispatched in the first subframe of the second radio frames need to be dispatched user's still scarce CCE numbers can with identical,
Can be different.
For example, the CCE numbers and second according to needed for failed scheduling user in the first subframe of the second radio frames are wireless
CCE numbers in first subframe of frame needed for failed scheduling user are determined in first subframe of the first current radio frames
For the CCE numbers required for the PDCCH for sending user-specific information：Dispatched not successfully in first subframe of the second radio frames
CCE numbers needed for user are that the CCE numbers used in successful dispatch user are in 12, the first subframe of the second radio frames
36, then be for the CCE numbers required for the PDCCH for sending user-specific information in first subframe of the first radio frames
12+36=48.
For example, needing to be dispatched user's still scarce CCE numbers and second according to scheduling in the first subframe of the second radio frames
CCE numbers in first subframe of radio frames needed for failed scheduling user determine first son of the first current radio frames
It is the CCE numbers required for the PDCCH for sending user-specific information in frame：Institute is dispatched in first subframe of the second radio frames
Need to be dispatched user's still scarce CCE numbers be in 8, the first subframe of the second radio frames used in successful dispatch user CCE
Number is 36, then is the CCE required for the PDCCH for sending user-specific information in first subframe of the first radio frames
Number is 8+36=44.
It is for sending user-specific in the first subframe of the first radio frames when the quantity of the second radio frames is more than one
CCE numbers required for the PDCCH of information are：
Wherein,For CCE needed for failed scheduling user in the first subframe of the second radio frames
The average value of number (or scheduling needs to be dispatched user's still scarce CCE numbers in the first subframe of the second radio frames),For in the first subframe of the second radio frames used in successful dispatch user CCE numbers average value.
For example, at least one described second radio frames include the 3rd radio frames and the 4th radio frames before the first radio frames,
CCE numbers wherein in the first subframe of the 3rd radio frames needed for failed scheduling user are 12, the first son of the 4th radio frames
CCE numbers in frame needed for failed scheduling user are to be made by successful dispatch user in 20, the first subframe of the 3rd radio frames
CCE numbers are 32, and the CCE numbers used in successful dispatch user are 24 in the first subframe of the 4th radio frames, then the
It is for the CCE numbers required for the PDCCH for sending user-specific information in first subframe of one radio frames：[(12+
20)/2]+[(32+24)/2]=44.
Step 122：It is determined that being the PDCCH for sending common control information in the first subframe of the first current radio frames
The CCE numbers distributed.
In first subframe of the first radio frames for for send CCE numbers that the PDCCH of common control information distributed by
It is the polymerization grade and the first radio frames for the PDCCH that sends common control information in first subframe of the first radio frames
Number in first subframe by the PDCCH for sending common control information is determined.For example, the first subframe of the first radio frames
In for the number of PDCCH for sending common control information be 2, be public for sending in the first subframe of the first radio frames
The PDCCH of control information polymerization grade is 8, then can determine that in the first subframe of the first radio frames to be for sending public control
The CCE numbers that the PDCCH of information is distributed are 2*8=16.
Because system has periodically to the scheduling of a part of common signal channel and information, therefore need in some subframes hair
The PDCCH for sending common control information is sent, need not then be sent for sending common control information in some subframes
PDCCH.In order that the demand for the PDCCH for sending common control information can be met by obtaining all subframes, in the embodiment of the present invention
In, it is determined that the method for sending the CCE numbers that the PDCCH of common control information is distributed, can also be：According to current public
The number of channel and common signal channel PDCCH polymerization grade determine what is distributed for sending the PDCCH of common control information
CCE numbers.For example, the number of current common channel is 1, and the polymerization grade 8 of the PDCCH on common signal channel, then can determine that is used for
The CCE numbers that the PDCCH of transmission common control information is distributed are 1*8=8.
Step 123：Determine to be used to send the CCE total numbers needed for PDCCH in the first subframe of the first radio frames.
The CCE total numbers being used in first subframe of the first radio frames needed for sending PDCCH are equal to the institute of the first radio frames
State in the first subframe as the CCE numbers required for the PDCCH for sending user-specific information and presently described first radio frames
First subframe in for the sum for sending the CCE numbers that the PDCCH of common control information is distributed.For example, the first nothing
CCE numbers in first subframe of line frame required for PDCCH for sending user-specific information are 44, the first radio frames
To be 8 for sending the CCE numbers that the PDCCH of common control information is distributed in first subframe, then the first radio frames are can determine that
The first subframe in the CCE total numbers that are used to send needed for PDCCH be 44+8=52.
It should be noted that step 121 can be performed before step 122, it can also perform after step 122, also
It can perform simultaneously, the embodiment of the present invention is not particularly limited to the order of step 121 and step 122.
PDCCH is located in preceding 1~3 OFDM symbol of subframe, the symbol numbers that PDCCH takes in a scheduling subframe
Indicated by CFI, CFI is bigger, the symbolic number that PDCCH takes is more, subframe can be used for the CCE of distribution resource more, i.e. CFI
Determine the assignable CCE numbers of PDCCH of the first subframe of first radio frames.Therefore can be by adjusting the big of CFI
It is small to realize the adjustment to the assignable CCE numbers of PDCCH of the first subframe of the first radio frames.
Step 130：Compare is used to send the CCE total numbers and first needed for PDCCH in the first subframe of the first radio frames
The assignable CCE numbers of PDCCH of first subframe of radio frames.
Specifically, determining the assignable CCE numbers of PDCCH of the first subframe of the first radio frames according to CFI value, then
Comparing is used for the first subframe for sending the CCE total numbers needed for PDCCH and the first radio frames in the first subframe of the first radio frames
The assignable CCE numbers of PDCCH magnitude relationship.If the CCE total numbers are more than the first subframe of first radio frames
The assignable CCE numbers of PDCCH, then perform step 140；If the CCE total numbers are less than the first of first radio frames
The assignable CCE numbers of PDCCH of subframe, then perform step 150；If the CCE total numbers are equal to first radio frames
The assignable CCE numbers of PDCCH of first subframe, then do not adjust CFI.
Step 140：Increase CFI, and it is integer that CFI, which meets 1≤CFI≤3, CFI,.
For example, the CCE total numbers being used in the first subframe of the first radio frames needed for sending PDCCH are 30, current CFI=
1, the assignable CCE numbers of PDCCH of the first subframe of corresponding first radio frames are N1, and 30>N1, it is therefore desirable to increase
CFI, untill the assignable CCE numbers of the PDCCH for meeting the first subframe that CCE total numbers are not more than the first radio frames, and
Meet：1≤CFI≤3, CFI is integer.
Step 150：Reduce CFI, and it is integer that CFI, which meets 1≤CFI≤3, CFI,.
For example, the CCE total numbers being used in the first subframe of the first radio frames needed for sending PDCCH are 60, current CFI=
3, the assignable CCE numbers of PDCCH of the first subframe of corresponding first radio frames are N2, and 60<N2, it is therefore desirable to reduce
CFI, untill meeting PDCCH assignable CCE number of the CCE total numbers not less than the first subframe of the first radio frames, and
CFI is met：1≤CFI≤3, CFI is integer.
It should be noted that above-mentioned steps 150 are not to realize the necessary step of the embodiment of the present invention, step 150 is intended only as
A kind of optional scheme of the embodiment of the present invention, is to the further perfect of the embodiment of the present invention.
Such scheme is wireless according to the CCE usage records of the second radio frames before the first current radio frames and first
For for sending the CCE numbers that the PDCCH of common control information is distributed in first subframe of frame, it is determined that current first is wireless
It is used to send the CCE total numbers needed for PDCCH in first subframe of frame, then according to the first of the first radio frames determined the son
It is used for the assignable CCE numbers of PDCCH for sending the first subframe of CCE total numbers and the first radio frames needed for PDCCH in frame
Magnitude relationship CFI is entered Mobile state adjustment so that the CCE quantity of the first subframe of the first radio frames can either meet user's need
Ask and be unlikely to excessive, improve PDCCH resource utilization；Meanwhile, such scheme determines that PDCCH is accounted for different from prior art
The mode of symbolic number, the algorithm of the above method is simpler, and operating process is more quick, it is thus possible to effectively reduce system
Operating pressure, improve signal transacting efficiency.Solve symbolic number unreasonable distribution that PDCCH in the prior art takes, no
Accurate the problem of, improve LTE system performance.
Optionally, before above-mentioned steps 150 are performed, methods described also includes：It is determined that the CFI values corresponding the after reducing
The assignable CCE numbers of PDCCH of first subframe of one radio frames are not less than in the first subframe of first radio frames and are used for
Send the CCE total numbers needed for PDCCH.
For example, the CCE total numbers being used in the first subframe of the first radio frames needed for sending PDCCH are 30, current CFI=
3, the assignable CCE numbers of PDCCH of the first subframe of corresponding first radio frames are N4, and 30<N4, it is therefore desirable to reduce
CFI.But if it is wireless that the assignable CCE quantity corresponding to CFI values (being assumed to be q) after kth time reduction is more than described first
Be used to sending CCE total numbers needed for PDCCH in first subframe of frame, and kth reduce for+1 time after CFI values (being assumed to be q-1)
Corresponding assignable CCE quantity in the first subframe of first radio frames less than being used to send the CCE needed for PDCCH
Total number, then do not do+1 adjustment of kth, regard the CFI values (q) after kth time adjustment as final CFI values.
By the manner, CFI can be avoided to be adjusted into endless loop, further improve the symbolic number for determining that PDCCH takes
Method, improve dynamic adjustment CFI precision, further improve PDCCH resource utilization, improve signal transacting effect
Rate.
Optionally, after step 130 is performed, before step 140, methods described also includes：
Step 160：It is determined that meet the second radio frames of constraints in the presence of at least one, the constraints is described the
The number of failed scheduling user is more than predetermined threshold value in first subframe of two radio frames.

In art scheme, the number of failed scheduling user is more than only in the first subframe that there are at least one second radio frames
Step 140 is just performed during predetermined threshold value, increases CFI；, whereas if being dispatched not successfully in the first subframe of all second radio frames
The number of user can not then adjust CFI no more than predetermined threshold value, be evaded with this because of only a few UE caused by accidentalia
Receive the risk that CFI adjustment caused by PDCCH unsuccessfully enters does not meet UE actual demands.
For example, predetermined threshold value=1, if in the first subframe of the second radio frames the number of failed scheduling user for 1 or
Person 0, then do not perform step 140.
Optionally, after step 130 is performed, before step 150, methods described also includes：
Step 170：It is determined that being adjusted not successfully in the first subframe of each radio frames at least one described second radio frames
The number of degree user is not more than predetermined threshold value.
Failed scheduling user in first subframe of each radio frames only at least one described second radio frames
Number be not more than predetermined threshold value in the case of, just perform step 150；Appoint if existed at least one described second radio frames
The number of failed scheduling user is more than predetermined threshold value in first subframe of one radio frames, then can not perform step 150.Protected with this
The assignable CCE numbers of PDCCH for demonstrate,proving the first subframe of the first radio frames disclosure satisfy that all UE demand.
For example, predetermined threshold value=2, if in the first subframe of at least one radio frames at least one second radio frames
The number of failed scheduling user is more than 2, then does not perform step 150.
By the manner, the method for determining the symbolic number that PDCCH takes can be further improved, dynamic adjustment CFI is improved
Precision so that the CCE quantity of the first subframe of the first radio frames can either meet user's request and be unlikely to excessive again, enter one
Step improves PDCCH resource utilization, improves the efficiency of signal transacting.

The assignable CCE numbers of PDCCH after, methods described also includes：
If the CCE total numbers are less than the assignable CCE numbers of PDCCH of the first subframe of first radio frames,
Determine whether to adjust not successfully in the first subframe that whether at least there are a radio frames at least one described second radio frames
The number for spending user is more than predetermined threshold value；
If it has, then increase CFI, and it is integer that CFI, which meets 1≤CFI≤3, CFI,.
For example, predetermined threshold value=3, if the CCE total numbers are less than the PDCCH of the first subframe of first radio frames
Assignable CCE numbers, but exist at least one described second radio frames and adjusted not successfully in the first subframe of 1 radio frames
The number for spending user is more than predetermined threshold value 3, then increases CFI, and CFI is met：1≤CFI≤3, CFI is integer.

Step 150 is not performed then.Only it is less than the assignable CCE of PDCCH of the first subframe of first radio frames in CCE total numbers
Step 150 is just performed when number and the product of scale factor.It can be distributed with the PDCCH of this first subframe for ensureing the first radio frames
CCE numbers can be more well-to-do, it is to avoid due to accidentally access UE cause the PDCCH of the first subframe of the first radio frames to distribute
The not enough risk of CCE numbers, and avoid CFI from being adjusted into endless loop.
For example, the CCE total numbers being used in the first subframe of the first radio frames determined needed for sending PDCCH are 100,
The assignable CCE numbers of PDCCH of first subframe of the first radio frames are N3=88, and scale factor is 0.9, due to 100>N3*
0.9=79.2, the CCE total numbers for being unsatisfactory in the first subframe of the first radio frames being used for needed for sending PDCCH are less than the first nothing
