Background technology
At Long Term Evolution (LTE, Long Term Evolution) in system, subscriber equipment (UE, User Equipment) before reception or transmission business datum, need to know that evolution base station (eNB, Evolved NodeB) configuration is to the Downlink Control Information (DCI, Downlink Control Information) of this subscriber equipment, this DCI is by Physical Downlink Control Channel (PDCCH, Physical Downlink Control channel) carrying.The size of each PDCCH is called polymerization rank (AL, Aggregation Level), can be polymerized by 1,2,4 or 8 continuous control channel unit (CCE, Control Channel Element).
UE knows oneself to need to detect which two kinds of DCI form (a kind of normal format by the configuration of transmission mode, a kind of rollback form), but UE does not know to carry the polymerization rank of the PDCCH of the DCI that sends to oneself, do not know to carry the CCE original position of the PDCCH of the DCI that sends to oneself yet, so UE goes blind Detecting is one by one done in the search volume with the length of two kinds of DCI that known, if UE detects cyclic redundancy check (CRC) (CRC, Cyclic Redundancy Check) be the radio network temporary identifier (RNTI that uses oneself, Radio Network Temporary Identifier) scrambling, UE just knows that this DCI issues oneself so, all fields of corresponding DCI form have also just been obtained, as modulation system, thereby further solve the DCI content.Process that Here it is so-called " blind Detecting ".The possible CCE position that UE seeks its PDCCH of carrying is called the search volume.The search volume 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 is used for the common control information that one group of UE (as DCI 3/3A) or all UE are issued in carrying, and USS is used for the DCI information that some UE are issued in carrying.DCI for different forms searches in different spaces.
Present DCI has tens kinds of forms, for the DCI of a kind of length (size), UE can a blind Detecting out, if the size of two kinds of form DCI is the same, can not increase the blind Detecting number of times, if the DCI of different length is arranged, need repeatedly 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, because DCI format1/1B/1D/2/2A can not occur simultaneously, after the transmission mode of UE was determined, a meeting blind check is a kind of form wherein, thereby need a kind of in blind Detecting rollback form and format 1/1B/1D/2/2A in DSS, be also the DCI of two kinds of size of blind check.The maximum blind Detecting of Rel-8 is 44 times.Two kinds of new form 2C and 4 have been increased in Rel-10,2C distinguishes by transmission mode, can not increase the blind Detecting number of times, format4 is a kind of new up multiple-input and multiple-output (UL MIMO) form that is used for, have new size, because of it in DSS transmission, therefore increase by 16 times for the blind Detecting number of times in its DSS of the UE that uses UL MIMO space.
The present inventor's discovery, in the prior art, the DCI of the upper carrying of PDCCH is limited, if increase the DCI quantity of the upper carrying of PDCCH, can increase the kind of format size, and then cause the increase of blind Detecting number of times.

Embodiment
In the prior art, strengthen PDCCH, namely many some DCI of carrying on PDCCH, can realize by compression DCI form, but the method for compression DCI form has increased the kind of format size, and then has caused the increase of blind Detecting number of times.
The embodiment of the present invention provides a kind of analytic method of control information, can when not increasing the blind Detecting number of times, strengthen again Physical Downlink Control Channel (PDCCH).The embodiment of the present invention also provides corresponding terminal.Below be elaborated respectively.
Consult Fig. 1, an embodiment of the analytic method of the control information that the embodiment of the present invention provides comprises:
101, obtain the numbering of the PDCCH place resource of carrying DCI, described resource is the carrier of PDCCH.
Downlink Control Information (DCI) carries by Physical Downlink Control Channel (PDCCH), and PDCCH is carried on again on the resources such as subframe, subcarrier, code word;
The resource at PDCCH place comprises the subframe of time domain at least, the subcarrier of frequency domain and the code word in spatial domain;
A fixed number is arranged on each resource, is 0～9 as the numbering of subframe in a radio frames, and the numbering of (Resource Block, RB) subcarrier is 1～12 in a Resource Block, and the numbering of code word is 1 and 2.
102, use the numbering of the resource of obtaining to carry out delivery calculating to the delivery parameter.
The delivery parameter can be that terminal itself is intrinsic, can be also that the base station is notified to terminal;
With described numbering, the delivery parameter is carried out delivery and calculate, with formulae express be: the numbering mod delivery parameter of resource; As when the delivery parameter is 2, to 2 deliverys, be 8 o'clock as the group frame number with the subframe numbering, to 2 deliverys, be exactly 8mod2, remainder is 0; Certainly the delivery parameter also can be other numerical value, as proper to several deliverys, depend on the variation of each field parameter of DCI, if the parameter of each field of DCI changes greatly, need more detailed information, as far as possible less with the DCI form that compresses, as get 5 deliverys, only have the subframe of 5 multiple just to use compressed format, all the other subframes are with normal format etc.
Due to the stability of main plot, consider to use normal DCI form on the main plot; Compression DCI form can be considered to use due to often deactivated and activation in auxiliary residential quarter.
103, according to the remainder of delivery calculating, judge the form of the DCI that carries on resource corresponding to described resource number.
On a resource, as on a subframe, except the rollback form, the base station only issues a kind of DCI of form, and the form of described DCI is except the rollback form, also comprise normal format and save bit format, that is to say, the DCI that the base station issues is except the rollback form, and another can only be normal format or save a kind of in bit format, the length of the DCI of described saving bit format is less than the length of the DCI of normal format, and the DCI of the upper carrying of described PDCCH comprises the DCI that saves bit format;
In step 102, by the remainder that described delivery calculates, judge the form of the DCI on described resource, when the remainder of delivery calculating was the first numerical value, the form of described DCI was normal format; When the remainder of delivery calculating was not the first numerical value, the form of described DCI was for saving bit format.
For example, subframe is numbered to 2 deliverys, when the delivery remainder is 0, the form of the form of described DCI is normal format, when remainder was not 0, the form of described DCI was for saving bit format, and terminal just can number to judge what form the DCI on subframe has been by the odd even of subframe like this.
Described saving bit format comprises compressed format, difference scheme and saving field format;
The described remainder that calculates by described delivery judges that the form of the DCI on described resource specifically comprises:
When the remainder that calculates when delivery was second value, the DCI of described saving bit format was the DCI of compressed format, the DCI of difference scheme or save a kind of in the DCI of field format;
When the remainder that calculates when delivery was third value, the DCI of described saving bit format was after removing the DCI of the saving bit format corresponding with described second value, remain a kind of in two kinds of saving bit format;
The remainder that calculates when delivery is not second and during third value, the DCI of described saving bit format be remove after the DCI of the saving bit format corresponding with described second value and third value remaining a kind of;
Can understand by following example: when the delivery parameter is 4, resource number is 4 o'clock, and remainder is 0, can stipulate that this DCI is normal format; When resource number is 5, remainder is 1, stipulates that this DCI is compressed format; When resource number is 6, remainder is 2, stipulates that this DCI is difference scheme; When resource number is 7, remainder is 3, stipulates that this DCI is for saving field format; Herein just for example, be in fact what time corresponding concrete form is not done restriction to the delivery remainder.
104, use the normal format of judging or the DCI length of saving bit format to carry out blind Detecting to PDCCH, obtain each field of described DCI.
Use the length of the DCI of normal format or saving bit format to carry out blind Detecting to PDCCH, because only have a kind of DCI of form on each resource except the rollback form, so can not increase the blind Detecting number of times, the length of saving the DCI of bit format is less than the length of the DCI of normal format, can hold more DCI like this on PDCCH.
The process of using DCI length to carry out blind Detecting comprises: use length and the DCI form of DCI to mate, the length of the form of every kind of DCI is basically not identical, and the DCI of every kind of form can have the field list of a correspondence; By CRC check, after confirming that DCI issues self, parse each field of DCI by mapping table.The below illustrates the process of blind Detecting:
The length of DCI is 44bits, the form that mates upper DCI according to the length of DCI is format 0, intercepting 44bits gets 44bits since a CCE, intercept the rear 16bits in this 44bits, do CRC check, to only have this 16bits be crc field and this crc field really with cell identifier (RNTI) scrambling of this UE, and CRC check just can be successful; CRC check just can be successfully after, in 44bits before 28bits by front and back order corresponding different field successively, some field may 5bits, some field may 1bit, comes in order; Can consult the field list of DCI format 0 to the understanding of the field of DCI, as table 1:
The field list of DCI format 0
Wherein,
Expression UL system bandwidth is specially Resource Block (RB, the resource block) number that comprises.Redundant bit refers to, when up system bandwidth is not more than with it the descending system bandwidth of pairing, in order to make DCI format 0 consistent with the information bit of DCI format 1A, need to increase redundant information bits, when for example upstream and downstream bandwidth all was 20MHz, DCI format 0 needed to increase by 1 bit.
The field of other DCI consists of with DCI format0 substantially similar, but the span of some field and bit number can change to some extent.
Described saving bit format comprises compressed format, difference scheme and saving field format;
The blind detection process that is directed to the blind detection process of saving bit format and above-mentioned normal format is similar; The below describes for example:
When DCI is compressed format, the length of DCI is 10bits, go format match with DCI with 10bits, when coupling has gone up formatX, so next after the intercepting, 8bits carries out CRC check, and after verification succeeds, front 2bits is by front and back order corresponding different field successively, use the mapping form of compressing to resolve the compressed field of the DCI that obtains described compressed format, described compressed field and not compressed field consist of each field of described DCI; The DCI of compressed format does not reduce on field, and just length has diminished, and as a field in compressed format DCI, the length when normal format is 32bits, and the length when compressed format may only have 10bits;
When DCI is difference scheme, the length of DCI is 9bits, go format match with DCI with 9bits, when coupling has gone up formatY, so next after the intercepting, 8bits carries out CRC check, after verification succeeds, front 1bits is by front and back order corresponding different field successively, the fiducial value of the respective field of the numerical value that the DCI of described difference scheme is represented by the difference field and the DCI of the last normal format is done calculating, restore the DCI of difference scheme at the original value of described field, the described numerical value that is represented by the difference field is the difference of described original value and fiducial value; For example: when being 1 by the numerical value of the expression of difference field, the fiducial value of the respective field of the DCI of the last normal format is 33 o'clock, and the original value to field that can calculate so difference scheme is 34; The DCI of difference scheme is with respect to normal format DCI, do not reduce on field, but length has diminished, as a field in difference scheme DCI, length when normal format is 5bits, the numerical value that can represent 0-31, for example represent 23, in difference scheme, this value may change not quite, as is 22 or 24, as long as 1bit transmits difference value-1 or 1 just passable, this field of difference scheme DCI has just reduced 4bits than normal format like this, and terminal can restore original value conversely according to differential principle; The fiducial value of the respective field of the numerical value that described DCI with described difference scheme is represented by the difference field and the DCI of the last normal format also comprises before doing and calculating: the fiducial value of the DCI of storage normal format;
When DCI is when saving bit format, the length of DCI is 8bits, go format match with DCI with 8bits, when coupling has gone up formatZ, so next after the intercepting, 8bits carries out CRC check, after verification succeeds, find that the field of front has all been saved, the history value of the respective field of the DCI of the last normal format of field use that the DCI of so described saving field format is saved is as the field of the DCI of described saving field format; What provide in this example is except the field of verification, other fields have all been saved, if except the field of verification, only have the part field to be saved, the history value of the respective field of the DCI of the normal format before the part field of being saved so adopts is as the field of the DCI of described saving field format, the history value of the respective field of the DCI of described the last normal format and each field of being saved field and consist of described DCI.
The formatX of corresponding compressed format in above-mentioned example, the formatY of corresponding difference scheme and the corresponding formatZ that saves bit format are the new forms that will define; X, Y, Z just for example, do not limit concrete form form of presentation.
No matter terminal will use the DCI of normal format still to save the DCI of bit format, must obtain by blind Detecting all fields of described DCI.
The embodiment of the present invention adopts the numbering of the PDCCH place resource obtain carrying DCI, judge the form of the DCI that carries on resource corresponding to resource number, the form of DCI comprises normal format and saving bit format, and the length of the DCI of saving bit format is less than the length of the DCI of normal format; The length of the DCI of the normal format that use is judged or saving bit format is carried out blind Detecting to PDCCH, obtains each field of described DCI.Compared with prior art, the length of the DCI of the Length Ratio normal format of the DCI of the analytic method saving bit format of the control information that the embodiment of the present invention provides is little, because only issue a kind of DCI of form on each resource of base station except the rollback form, so do not increase the kind of DCI length, realized having strengthened again Physical Downlink Control Channel when not increasing the blind Detecting number of times.
Alternatively, on the basis of above-described embodiment, also comprise after step 101: receive the delivery parameter that the base station issues.
Consult Fig. 2, another embodiment of the analytic method of the control information that the embodiment of the present invention provides comprises:
201, receive the information that the base station sends, for saving the DCI of bit format, described resource is the carrier of PDCCH according to the DCI form on the information acquisition allocated resource of base station transmission.
There is the DCI of which kind of form can be by base station transmitting order to lower levels notification terminal on which resource, (RRC can be controlled by Radio Resource in the base station, Radio Resource Control) resource identification of bit format DCI is saved in the carrying of signaling terminal, as 12 subcarriers, can use specifically which subcarrier of 4bits sign.Whether the DCI that the RRC signaling that can be also the base station by 1bit is sent on specific resources is the indication information of saving the DCI of bit format, is to represent that its DCI was for saving the DCI of bit format at 1 o'clock as receive this RRC signaling on 1 work song frame.
The sign of DCI place allocated resource that can be by receiving saving bit format that the base station sends; According to the DCI of the DCI form on the sign acquisition allocated resource of described allocated resource for the saving bit format.
Can whether be also the indication information of saving bit format by the form that receives the DCI on allocated resource that the base station sends; When being, obtain DCI form on allocated resource for saving the DCI of bit format according to described indication information.
202, use the length of the DCI of described saving bit format to carry out blind Detecting to PDCCH, obtain each field of described DCI.
The DCI that carries on the resource of the described sign indication that receives is for saving the DCI of bit format, or when described indication information when being, being illustrated in the DCI that carries on allocated resource is the DCI that saves bit format, use the length of the DCI that saves bit format to carry out blind Detecting to PDCCH, because only have a kind of DCI of form on each resource except the rollback form, so can not increase the blind Detecting number of times, the length of saving the DCI of bit format is less than the length of the DCI of normal format, can hold more DCI like this on PDCCH.
Described saving bit format comprises compressed format, difference scheme and saving field format;
The blind detection process that is directed to the blind detection process of saving bit format and the format0 in above-described embodiment is similar; The below describes for example:
When DCI is compressed format, the length of DCI is 10bits, go format match with DCI with 10bits, when coupling has gone up formatX, so next after the intercepting, 8bits carries out CRC check, and after verification succeeds, front 2bits is by front and back order corresponding different field successively, use the mapping form of compressing to resolve the compressed field of the DCI that obtains described compressed format, described compressed field and not compressed field consist of each field of described DCI; The DCI of compressed format does not reduce on field, and just length has diminished, and as a field in compressed format DCI, the length when normal format is 32bits, and the length when compressed format may only have 10bits;
When DCI is difference scheme, the length of DCI is 9bits, go format match with DCI with 9bits, when coupling has gone up formatY, so next after the intercepting, 8bits carries out CRC check, after verification succeeds, front 1bits is by front and back order corresponding different field successively, the fiducial value of the respective field of the numerical value that the DCI of described difference scheme is represented by the difference field and the DCI of the last normal format is done calculating, restore the DCI of difference scheme at the original value of described field, the described numerical value that is represented by the difference field is the difference of described original value and fiducial value; For example: when being 1 by the numerical value of the expression of difference field, the fiducial value of the respective field of the DCI of the last normal format is 33 o'clock, and the original value to field that can calculate so difference scheme is 34; The DCI of difference scheme is with respect to normal format DCI, do not reduce on field, but length has diminished, as a field in difference scheme DCI, length when normal format is 5bits, the numerical value that can represent 0-31, for example represent 23, in difference scheme, this value may change not quite, as is 22 or 24, as long as 1bit transmits difference value-1 or 1 just passable, this field of difference scheme DCI has just reduced 4bits than normal format like this, and terminal can restore original value conversely according to differential principle; The fiducial value of the respective field of the numerical value that described DCI with described difference scheme is represented by the difference field and the DCI of the last normal format also comprises before doing and calculating: the fiducial value of the DCI of storage normal format;
When DCI is when saving bit format, the length of DCI is 8bits, go format match with DCI with 8bits, when coupling has gone up formatZ, so next after the intercepting, 8bits carries out CRC check, after verification succeeds, find that the field of front has all been saved, the history value of the respective field of the DCI of the last normal format of field use that the DCI of so described saving field format is saved is as the field of the DCI of described saving field format; What provide in this example is except the field of verification, other fields have all been saved, if except the field of verification, only have the part field to be saved, the history value of the respective field of the DCI of the normal format before the part field of being saved so adopts is as the field of the DCI of described saving field format, the history value of the respective field of the DCI of described the last normal format and each field of being saved field and consist of described DCI.
The formatX of corresponding compressed format in above-mentioned example, the formatY of corresponding difference scheme and the corresponding formatZ that saves bit format are the new forms that will define; X, Y, Z just for example, do not limit concrete form form of presentation.
No matter terminal will use the DCI of normal format still to save the DCI of bit format, must obtain by blind Detecting all fields of described DCI.
203, when described indication information when being no on allocated resource, use the length of normal format DCI to carry out blind Detecting to PDCCH, each field that obtains described DCI is used.
When described indication information is noly to be, the form that DCI is described is normal format, length as the DCI of normal format is 32bits, that length according to this 32bits is done blind Detecting, at first intercept 16bits and carry out CRC check, when CRC check success, know that this DCI is after sending to the DCI of oneself, with other 16bits according to sequencing corresponding different field successively.
The embodiment of the present invention adopts the information that the base station sends that receives, and for saving the DCI of bit format, described resource is the carrier of PDCCH according to the DCI form on the information acquisition allocated resource of base station transmission; Use the length of the DCI of described saving bit format to carry out blind Detecting to PDCCH, each field that obtains described DCI is used.Compared with prior art, the length of the DCI of the Length Ratio normal format of the DCI of the analytic method saving bit format of the control information that the embodiment of the present invention provides is little, because only issue a kind of DCI of form on each resource of base station except the rollback form, so do not increase the kind of DCI length, realized when not increasing the blind Detecting number of times, strengthened again Physical Downlink Control Channel (PDCCH).
Alternatively, on the basis of above-described embodiment, also comprise after step 201: the cycle that receives the DCI appearance of described saving bit format.As the cycle be 3 o'clock, that carry in 1 work song frame is the DCI that saves bit format, 4 work song frames and the carrying of 7 work song frames be also the DCI that saves bit format.
