Background technology
In Long Term Evolution (LTE, Long Term Evolution) system, subscriber equipment (UE, User Equipment)
Before receiving or sending business datum, need to know that evolution base station (eNB, Evolved NodeB) is allocated to this subscriber equipment
Downlink Control Information (DCI, Downlink Control Information), this DCI passes through Physical Downlink Control Channel
(PDCCH, Physical Downlink Control channel) carries.The size of each PDCCH be referred to as being polymerized rank (AL,
Aggregation Level), Channel Elements (CCE, Control Channel can be controlled by 1,2,4 or 8 continuous print
Element) it is polymerized.
UE is known by the configuration of transmission mode oneself to be needed to detect which two kinds of DCI format (a kind of normal format, one time
Backspace formula), but UE does not knows to carry the polymerization rank of the PDCCH of the DCI being sent to oneself, does not knows that carrying is sent to oneself yet
The CCE original position of PDCCH of DCI, then UE goes to do search volume the blindest by the length of two kinds of already known DCI
Detection, if UE detects cyclic redundancy check (CRC), (CRC, Cyclic Redundancy Check) is with the wireless network of oneself
Temporary identifier (RNTI, Radio Network Temporary Identifier) scrambles, then UE is known that this DCI is
Issue oneself, the most just obtained all fields of corresponding DCI format, such as modulation system, thus solve further in DCI
Hold.Here it is so-called " blind Detecting " process.UE finds the possible CCE position of its PDCCH of carrying and is referred to as search volume.Search sky
Between can be divided into public search space (CSS, Common search space) and user equipment specific search volume (USS or DSS,
UE-specific/Dedicated search space), CSS issues one group of UE (such as DCI 3/3A) or all UE for carrying
Common control information, USS issues the DCI information of some UE for carrying.For the DCI of different forms at different skies
Search between.
Present DCI has ten several forms, for the DCI of a kind of length (size), then UE can a blind Detecting out,
If the size of two kinds of form DCI is the same, then will not increasing blind Detecting number of times, if there being the DCI of different length, then needing many
Secondary blind Detecting.In the 8th version (Rel-8), CSS needs blind Detecting DCI format 1C and DCI format 0/1A/3/3A
(size of the DCI of these 4 kinds of forms is identical), namely needs the DCI of two kinds of size of blind Detecting.In DSS, due to DCI
Format1/1B/1D/2/2A will not occur simultaneously, after the transmission mode of UE determines, and only meeting blind check one of which form, because of
And in DSS, need the one in blind Detecting rollback form and format 1/1B/1D/2/2A, also it is two kinds of size of blind check
DCI.The maximum blind Detecting of Rel-8 is 44 times.Adding two kinds of new form 2C and 4 in Rel-10,2C passes through transmission mode
Distinguishing, will not increase blind Detecting number of times, format4 is then a kind of new for up multiple-input and multiple-output (UL MIMO) lattice
Formula, has new size, because it transmits at DSS, therefore for using the blind Detecting number of times in its DSS space of UE of UL MIMO to increase
Add 16 times.
It was found by the inventors of the present invention that in the prior art, the DCI of the upper carrying of PDCCH is limited, if increased on PDCCH

Detailed description of the invention
In the prior art, PDCCH to be strengthened, namely some DCI of multiple-bearer on PDCCH, can be by compression DCI
Form realizes, but the method for compression DCI format adds the kind of format size, and then causes the increasing of blind Detecting number of times
Add.
The embodiment of the present invention provide a kind of analytic method controlling information, can while not increasing blind Detecting number of times,
Enhance again Physical Downlink Control Channel (PDCCH).The embodiment of the present invention also provides for corresponding terminal.Carry out individually below in detail
Explanation.
Refering to Fig. 1, an embodiment of the analytic method of the control information that the embodiment of the present invention provides includes:
101, obtaining the numbering of the PDCCH place resource of carrying DCI, described resource is the carrier of PDCCH.
Downlink Control Information (DCI) is carried by Physical Downlink Control Channel (PDCCH), and PDCCH is carried on again
In the resources such as subframe, subcarrier, code word；
The resource at PDCCH place at least includes the subframe of time domain, the subcarrier of frequency domain and the code word in spatial domain；
A fixed number is had, as the numbering of subframe is 0～9 in a radio frames, a money in each resource
In the block of source, the numbering of (Resource Block, RB) subcarrier is 1～12, and the numbering of code word is 1 and 2.
102, use the numbering of the resource obtained that delivery parameter is carried out delivery calculating.
Delivery parameter can be terminal itself intrinsic, it is also possible to be that base station notifies to terminal；
By described numbering, delivery parameter is carried out delivery calculating, by formulae express be: the numbering mod delivery parameter of resource；
As when delivery parameter is 2, with subframe number to 2 deliverys, as when subframe number is 8, to 2 deliverys, it is simply that 8mod2, remainder
It is 0；Certainly delivery parameter can also be other numerical value, as proper to several deliverys, depends on the change of each field parameter of DCI
Change, if the Parameters variation of each field of DCI is relatively big, need information in greater detail, then the DCI format of few compression of trying one's best, as
Taking 5 deliverys, the subframe of the multiple of only 5 is just by compressed format, remaining subframe normal format etc..
Stability due to main plot, it is considered to use normal DCI format on main plot；Secondary cell is due to the most deactivated
And activation, it may be considered that use compression DCI format.
103, the remainder calculated according to delivery, it is judged that the form of the DCI of carrying in the resource that described resource number is corresponding.
In a resource, as in a subframe, except rollback form, base station only issues the DCI of a kind of form, described
The form of DCI in addition to rollback form, also include normal format and save bit format, say, that the DCI that base station issues except
Rollback form, another can only be the one in normal format or saving bit format, the DCI's of described saving bit format
The length length less than the DCI of normal format, on described PDCCH, the DCI of carrying includes the DCI saving bit format；
In a step 102, the remainder calculated by described delivery, judge the form of DCI in described resource, work as delivery
When the remainder calculated is the first numerical value, the form of described DCI is normal format；The remainder calculated when delivery is not the first numerical value
Time, the form of described DCI is for saving bit format.
Such as, subframe number is to 2 deliverys, and when delivery remainder is 0, the form of the form of described DCI is normal format, when
When remainder is not 0, the form of described DCI is for saving bit format, and such terminal just can be numbered by the odd even of subframe and be sentenced
DCI in disconnected subframe is any form.
Described saving bit format includes compressed format, difference scheme and saving field format；
The described remainder calculated by described delivery, it is judged that the form of the DCI in described resource specifically includes:
When the remainder that delivery calculates is second value, the DCI that DCI is compressed format of described saving bit format is poor
One in the DCI of cellular or the DCI of saving field format；
When the remainder that delivery calculates is third value, the DCI of described saving bit format is for removing and described second number
After the DCI of the saving bit format that value is corresponding, remain two kinds of one saved in bit format；
The remainder calculated when delivery is not second and during third value, and the DCI of described saving bit format is for removing and institute
State remaining one after the DCI of the second value saving bit format corresponding with third value；
Can understand by following example: when delivery parameter is 4, and resource number is 4, remainder is 0, can specify that this
DCI is normal format；When resource number is 5, and remainder is 1, it is stipulated that this DCI is compressed format；When resource number is 6, and remainder is
2, it is stipulated that this DCI is difference scheme；When resource number is 7, and remainder is 3, it is stipulated that this DCI is for saving field format；It is herein
Citing, the concrete form being actually the most corresponding to delivery remainder does not limits.
104, the DCI length using the normal format judged or saving bit format carries out blind Detecting to PDCCH, obtains
Each field of described DCI.
The length using the DCI of normal format or saving bit format carries out blind Detecting to PDCCH, because removing in each resource
Rollback form only has the DCI of a kind of form, so blind Detecting number of times will not be increased, saves the length of the DCI of bit format
It is less than the length of the DCI of normal format, so can accommodate more DCI on PDCCH.
The process using DCI length to carry out blind Detecting includes: use the length of DCI to mate with DCI format, every kind
The length of the form of DCI is substantially all and differs, and the DCI of every kind of form can have a corresponding field list；By CRC school
Test, after confirming that DCI is intended for self, parsed each field of DCI by mapping table.Blind Detecting is exemplified below
Process:
The a length of 44bits of DCI, the form matching DCI according to the length of DCI is format 0, intercept 44bits from
One CCE starts to take 44bits, intercepts the rear 16bits in this 44bits, does CRC check, and only this 16bits is strictly CRC
Field and this crc field cell identifier (RNTI) of this UE scramble, and CRC check just can success；CRC check just can success
After, in 44bits, front 28bits is then corresponding in turn to different fields by tandem, the possible 5bits of some field, some field
Possible 1bit, comes in order；Understanding to the field of DCI see the field list of DCI format 0, such as table 1:
The field list of DCI format 0
Wherein,Represent UL system bandwidth, the Resource Block specially comprised (RB, resource block) number.Redundancy
Bit refers to, when up system bandwidth is not more than paired descending system bandwidth, in order to make DCI format 0
Consistent with the information bit of DCI format 1A, needing to increase redundant information bits, such as upstream and downstream bandwidth is all 20MHz
Time, DCI format 0 needs to increase by 1 bit.
The field of other DCI constitutes substantially similar with DCI format0, but the span of some field and bit number
Can be varied from.
Described saving bit format includes compressed format, difference scheme and saving field format；
The blind detection process being directed to save bit format is similar with the blind detection process of above-mentioned normal format；Illustrate below
Illustrate:
When DCI is compressed format, a length of 10bits of DCI, goes the format match with DCI with 10bits, works as coupling
Go up formatX, then after next intercepting, 8bits carries out CRC check, and after verifying successfully, front 2bits is then depended on by tandem
The field that secondary correspondence is different, uses the mapping form of compression to carry out resolving the word compressed of the DCI obtaining described compressed format
Section, the described field compressed and un-compressed field constitute each field of described DCI；The DCI of compressed format, in field
Not not reducing, simply length diminishes, such as a field in compressed format DCI, and a length of when normal format
32bits, the length when compressed format may only have 10bits；
When DCI is difference scheme, a length of 9bits of DCI, goes the format match with DCI with 9bits, when matching
FormatY, then after next intercepting, 8bits carries out CRC check, and after verifying successfully, front 1bits then presses tandem successively
Corresponding different field, the numerical value that the DCI of described difference scheme is represented by difference field and the DCI of the last normal format
The reference value of respective field calculate, restore the DCI original value in described field of difference scheme, described by difference field
The difference that numerical value is described original value and reference value represented；Such as: when being 1 by the numerical value of the expression of difference field, recently
When the reference value of the respective field of the DCI of normal format is 33, then former to field of difference scheme can be calculated
Initial value is 34；The DCI of difference scheme, relative to normal format DCI, field does not reduce, but length diminishes, such as difference
A field in form DCI, a length of 5bits when normal format, the numerical value of 0-31 can be represented, such as, represent 23,
In difference scheme, this value may change little, as 22 or 24, if 1bit transmission difference value-1 or 1 the most permissible, so
This field of difference scheme DCI just decreases 4bits than normal format, and terminal then can be reduced according to differential principle in turn
Go out original value；The DCI's of the described numerical value that the DCI of described difference scheme is represented by difference field and the last normal format
The reference value of respective field also includes before calculating: the reference value of the DCI of storage normal format；
When DCI for save bit format time, a length of 8bits of DCI, go the format match with DCI with 8bits, when
Next mixed formatZ, then after intercepting, 8bits carries out CRC check, after verify successfully, discovery field above all by
Save, then the field that the DCI of described saving field format is saved uses the corresponding word of the DCI of the last normal format
The history value of section is as the field of the DCI of described saving field format；Be given in this example is in addition to the field of verification, other
Field is all saved, if in addition to the field of verification, only part field is saved, then the part field being saved uses
The history value of the respective field of the DCI of normal format before as the field of the DCI of described saving field format, described recently
The history value of the respective field of the DCI of normal format and be not saved field and constitute each field of described DCI.
The formatX of corresponding compressed format in above-mentioned example, the formatY of corresponding difference scheme and corresponding saving bit lattice
The formatZ of formula is intended to the new form of definition；X, Y, Z simply citing, does not limit concrete form form of presentation.
The DCI of terminal normal format to be used or save the DCI of bit format, must be obtained by blind Detecting
All fields of described DCI.
The embodiment of the present invention uses the numbering of the PDCCH place resource obtaining carrying DCI, it is judged that the money that resource number is corresponding
The form of the DCI of carrying on source, the form of DCI includes normal format and saves bit format, saving the length of the DCI of bit format
The degree length less than the DCI of normal format；Use the length pair of the DCI of the normal format judged or saving bit format
PDCCH carries out blind Detecting, obtains each field of described DCI.Compared with prior art, the control letter that the embodiment of the present invention provides
It is little, because removing in each resource in base station that the analytic method of breath saves the length of the DCI of the bit format length than the DCI of normal format
Rollback form only issues the DCI of a kind of form, so not increasing the kind of DCI length, it is achieved that do not increasing blind Detecting
While number of times, enhance again Physical Downlink Control Channel.
Alternatively, on the basis of above-described embodiment, also include after step 101: receive the delivery parameter that base station issues.
Refering to Fig. 2, another embodiment of the analytic method of the control information that the embodiment of the present invention provides includes:
201, receiving the information that base station sends, the information acquisition sent according to base station specifies the DCI format in resource to be joint
Saving the DCI of bit format, described resource is the carrier of PDCCH.
The DCI having which kind of form in which resource can be notified terminal by base station transmitting order to lower levels, and nothing can be passed through in base station
Line resources control (RRC, Radio Resource Control) signals terminal carrying and saves the resource mark of bit format DCI
Which know, such as 12 subcarriers, it is possible to use 4bits mark specifically subcarrier.Can also be base station pass through 1bit RRC letter
Whether the DCI that is sent in specific resources of order is the instruction information of the DCI saving bit format, as received this on 1 work song frame
RRC signaling is to represent when 1 that its DCI is the DCI saving bit format.
The mark of resource can be specified by receiving the DCI place of the saving bit format that base station sends；According to described finger
The mark determining resource obtains the DCI specifying the DCI format in resource to be saving bit format.
Whether the form at the DCI specified in resource that can also send by receiving base station is the finger saving bit format
Show information；During according to described instruction information for being, it is thus achieved that specifying the DCI format in resource is to save the DCI of bit format.
202, the length using the DCI of described saving bit format carries out blind Detecting to PDCCH, obtains each of described DCI
Individual field.
When in the resource of the described mark instruction received, the DCI of carrying is the DCI saving bit format, or when described finger
When showing information for being, represent that specifying the DCI of carrying in resource be the DCI saving bit format, use and save bit format
The length of DCI carries out blind Detecting to PDCCH, because only having the DCI of a kind of form except rollback form in each resource, so not
Can increase blind Detecting number of times, the length of the DCI saving bit format is less than the length of the DCI of normal format, so at PDCCH
On can accommodate more DCI.
Described saving bit format includes compressed format, difference scheme and saving field format；
It is directed to the blind detection process class of the blind detection process saving bit format and the format0 in above-described embodiment
Seemingly；Citing below illustrates:
When DCI is compressed format, a length of 10bits of DCI, goes the format match with DCI with 10bits, works as coupling
Go up formatX, then after next intercepting, 8bits carries out CRC check, and after verifying successfully, front 2bits is then depended on by tandem
The field that secondary correspondence is different, uses the mapping form of compression to carry out resolving the word compressed of the DCI obtaining described compressed format
Section, the described field compressed and un-compressed field constitute each field of described DCI；The DCI of compressed format, in field
Not not reducing, simply length diminishes, such as a field in compressed format DCI, and a length of when normal format
32bits, the length when compressed format may only have 10bits；
When DCI is difference scheme, a length of 9bits of DCI, goes the format match with DCI with 9bits, when matching
FormatY, then after next intercepting, 8bits carries out CRC check, and after verifying successfully, front 1bits then presses tandem successively
Corresponding different field, the numerical value that the DCI of described difference scheme is represented by difference field and the DCI of the last normal format
The reference value of respective field calculate, restore the DCI original value in described field of difference scheme, described by difference field
The difference that numerical value is described original value and reference value represented；Such as: when being 1 by the numerical value of the expression of difference field, recently
When the reference value of the respective field of the DCI of normal format is 33, then former to field of difference scheme can be calculated
Initial value is 34；The DCI of difference scheme, relative to normal format DCI, field does not reduce, but length diminishes, such as difference
A field in form DCI, a length of 5bits when normal format, the numerical value of 0-31 can be represented, such as, represent 23,
In difference scheme, this value may change little, as 22 or 24, if 1bit transmission difference value-1 or 1 the most permissible, so
This field of difference scheme DCI just decreases 4bits than normal format, and terminal then can be reduced according to differential principle in turn
Go out original value；The DCI's of the described numerical value that the DCI of described difference scheme is represented by difference field and the last normal format
The reference value of respective field also includes before calculating: the reference value of the DCI of storage normal format；
When DCI for save bit format time, a length of 8bits of DCI, go the format match with DCI with 8bits, when
Next mixed formatZ, then after intercepting, 8bits carries out CRC check, after verify successfully, discovery field above all by
Save, then the field that the DCI of described saving field format is saved uses the corresponding word of the DCI of the last normal format
The history value of section is as the field of the DCI of described saving field format；Be given in this example is in addition to the field of verification, other
Field is all saved, if in addition to the field of verification, only part field is saved, then the part field being saved uses
The history value of the respective field of the DCI of normal format before as the field of the DCI of described saving field format, described recently
The history value of the respective field of the DCI of normal format and be not saved field and constitute each field of described DCI.
The formatX of corresponding compressed format in above-mentioned example, the formatY of corresponding difference scheme and corresponding saving bit lattice
The formatZ of formula is intended to the new form of definition；X, Y, Z simply citing, does not limit concrete form form of presentation.
The DCI of terminal normal format to be used or save the DCI of bit format, must be obtained by blind Detecting
All fields of described DCI.
203, specifying in resource when described instruction information is no, using the length of normal format DCI that PDCCH is carried out
Blind Detecting, each field obtaining described DCI uses.
When described instruction information is no, illustrate that the form of DCI is normal format, such as DCI a length of of normal format
32bits, that is done blind Detecting according to the length of this 32bits, first intercepts 16bits and carry out CRC check, when CRC check becomes
Other 16bits, after knowing that this DCI is destined to the DCI of oneself, are corresponding in turn to different fields according to sequencing by merit.
The embodiment of the present invention uses and receives the information that base station sends, and specifies in resource according to the information acquisition that base station sends
DCI format is to save the DCI of bit format, and described resource is the carrier of PDCCH；Use the DCI's of described saving bit format
Length carries out blind Detecting to PDCCH, and each field obtaining described DCI uses.Compared with prior art, the present invention implements
The length of the DCI of the analytic method saving bit format of the control information that example the provides length than the DCI of normal format is little, Yin Ji
The DCI of a kind of form is only issued except rollback form, so not increasing the kind of DCI length in each resource of standing, it is achieved that
While not increasing blind Detecting number of times, enhance again Physical Downlink Control Channel (PDCCH).
Alternatively, on the basis of above-described embodiment, also include after step 201: receive described saving bit format
The cycle that DCI occurs.As the cycle be 3 time, in 1 work song frame carrying is save bit format DCI, 4 work song frames and 7 work song frames
Carrying is also the DCI saving bit format.
