Description
Technical field
The Downlink Control Information optimized the present invention relates to a kind of pair of uplink hybrid automatic repeat request (UL HARQ) is real
Existing method, belongs to wireless communication technology field.
Background technique
Currently, forth generation cell mobile communication systems (IMT-advanced) have become the mobile communication technology of mainstream
One of.In cell mobile communication systems, forward error correction (FEC) coding techniques and automatic repeat request (ARQ) etc. are generallyd use
Method carries out Error Control, so that it is guaranteed that service quality.In the prior art, ARQ and FEC are used in mixed way mostly, i.e., it is so-called
Hybrid automatic repeat-request (HARQ) mechanism.In HARQ mechanism, the number retransmitted is reduced using FEC, is reduced the bit error rate, is made
Guarantee the quality of packet data transmission with the re-transmission of ARQ and CRC check.With the rapid development to highly reliable business demand,
HARQ has become a key technology in cell mobile communication systems, and has obtained in-depth study.
It is anti-about downlink (Downlink) and the HARQ of uplink (Uplink) in current LTE/LTE-A protocol specification
Infeed mechanism is respectively:
1) HARQ feedback of downlink is the ascending control information (UCI) by various formats come what is fed back, wherein Format
3 can support the disposable feedback of more member carriers (most 2 transmission blocks on each member carrier)；And ascending control information was both
It can be carried in PUCCH (physical uplink control channel), can also be uploaded at PUSCH (Physical Uplink Shared Channel)
It send.
2) HARQ feedback of uplink has 2 kinds of mechanism at present:
Synchronous non-self-adapting mechanism, corresponding PHICH mode: if it is ACK, it is believed that PUSCH transmission block is sent successfully, but
Information still retains；If it is NACK, then a RTT (Round-Trip Time, two-way time) trigger afterwards it is synchronous it is non-from
It adapts to retransmit, it may be assumed that retransmission time is fixed and corresponding running time-frequency resource, modulation and coding strategy are also all constant.
Synchronous self-adapting mechanism, corresponding 0/4 mode of DCI: if on the same Transmission Time Interval, user equipment was both
It receives PHICH and receives DCI 0/4 again, then PHICH can be ignored, whether the transmission block of last time sends successful by DCI 0/4
NDI (new data instruction) indicate.If NDI is not inverted, illustrate that data do not receive successfully, this is one adaptive
The uplink authorization of re-transmission: although requiring retransmission time to still need to meet RTT multiple proportion relative to first time transmission, when corresponding
Frequency resource, modulation and coding strategy or redundancy versions should all be subject to the Downlink Control Information；If NDI is inverted,
Illustrate that this is the scheduling of a new data, also recessiveness illustrates that last transmitting is successfully received, and user equipment can be removed
The background information of secondary transmission block.
If to support 32 member carriers under carrier aggregation scene, the current 3GPP specification under cross-carrier scheduling
Following problem is potentially present of in uplink HARQ feedback mechanism.
The problem of PHICH mode:
1) PHICH is only supported at control domain, it is not possible to be extended to data field, therefore the resource of PHICH is a bottleneck；
2) single user's equipment needs to occupy multiple PHICH group, and the number of PHICH group is that a system is matched
Value is set, it is related with the bandwidth of carrier wave, it is more valuable；
3) collision probability of increasing with member carrier number, PHICH resource can skyrocket.
The problem of 0/4 mode of DCI:
1) only when user equipment is there are in the case where uplink scheduling demand (new data or adaptive retransmission), this recessiveness
HARQ feedback mode could be used；And the case where for new data, it not can guarantee the ACK/NACK of last upstream data
Meet the requirement of HARQ time；
2) DCI 0/4 is to realize uplink authorization in itself, and recessive HARQ feedback indicative function is a by-product
Product, therefore it is required that it to do excessive non-own job requirement also not-so-practical.
In the prior art, after user equipment receives the ACK that PHICH mode is expressed, it is not known that this ACK's is " true
It is false ", it to lean on same Transmission Time Interval or subsequent transmission time interval and whether there is the uplink authorization of corresponding HARQ instance treatment process
Information/Downlink Control Information further confirms that, so sometimes resulting in user equipment does some meaningless blind examinations.Such as: it uses
That family equipment receives is a true ACK, and does not have the scheduling of new data on the Transmission Time Interval, if user equipment knows
These information, then blind examination DCI 0/4 no longer can be removed in the specific search space the corresponding UE of the member carrier, especially
Maximum blind examination number of the DCI 4 on a member carrier is 16, and lower 32 member carriers of extreme case are also this means that 32*16
=512 blind examinations.
Summary of the invention
In view of the deficiencies of the prior art, technical problem to be solved by the present invention lies in provide a kind of optimization ascending HARQ

Specific embodiment
Technology contents of the invention are described in further detail combined with specific embodiments below.
The invention proposes a kind of new realization sides Downlink Control Information (Downlink Control Information)
Method, for solving the problems, such as that user equipment uplink HARQ feedback mechanism is potentially present of some under cross-carrier scheduling.These problems tool
Body is described as follows:
In the specific search space the corresponding UE of the main member carrier of user equipment, Downlink Control Information is needed to meet uplink
Under the premise of HARQ sequential relationship, for each uplink active member carrier wave of user equipment, indicate that it belongs to following situations
In it is any:
Situation one: there are the adaptive of the scheduling authorization of new upstream data or the last upstream data on the member carrier
Authorization should be retransmitted；
Situation two: not having the scheduling authorization of new upstream data on the member carrier, and if desired retransmits upstream data
It is the mode using non-adaptive re-transmission；
If belonging to situation one, need further to indicate the more bright of corresponding uplink authorization information/Downlink Control Information
Really or the smaller polymerization grade information of range is accelerated blind so that user equipment does not have to traverse all candidate PDCCH/EPDCCH
Inspection process is to realize more efficient uplink authorization information/Downlink Control Information blind examination；
If belonging to situation two, need disposably to carry the ACK/ of all transmission blocks on all this member carriers
Nack message realizes the function of similar " block ACK ", to improve the execution efficiency of HARQ feedback.
In order to meet above-mentioned requirement, the present invention is provided at least two individual cells in Downlink Control Information, respectively
It is named as CC_Feedback_List and TB_Feedback_List.Letter is controlled for the downlink with above-mentioned two individual cells
Breath is claimed in the present invention with DCI X (X refers to and the current defined unduplicated number of format, such as 5 or 6 numbers) generation.The downlink
Control information DCI X only emits on the specific search space the corresponding UE of main member carrier, uses C-RNTI disturbing as its CRC
Code.
In DCI X, the data type of cell CC_Feedback_List is bit map, and the number of bit (bit) takes
The uplink member carrier number being certainly scheduled in the user equipment, the sequence of bit indicate the index of these uplink member carriers
(index).Here, the bit in CC_Feedback_List, subsequent referred to as CC bit.In the uplink tune of the member carrier
It spends on Transmission Time Interval, both there is no new data dispatching requirement, also use non-adaptive retransmission scheme simultaneously for retransmitting, that
The correspondence bit of the member carrier is set to " 1 ".Other situations are set to " 0 ", are set to expressed by " 0 " and are meant that: carrying in the member
On the uplink scheduling Transmission Time Interval of wave, there are uplink authorization information/Downlink Control Information, the DCI may be one from
The re-transmission of adaptation is also likely to be new data.
On the other hand, the data type of cell TB_Feedback_List is also bit map, and the number of bit depends on
The transmission block number sent in the scheduled all uplink member carriers of the user equipment；Each member carrier correspond at least one,
Most 2 transmission blocks.The sequence of bit indicates the index (index) of these transmission blocks.Here, in TB_Feedback_List
Bit, subsequent referred to as TB bit.Wherein, the index calculation of transmission block is as follows on i-th (i is positive integer) a member carrier:
TB1-index=m+2n；
TB2-index=m+2n+1 (if spatial reuse)；
Wherein, m, n respectively indicate the member carrier number of single transmission block and double transmission in (i-1) a member carrier of front
The member carrier number of block；
It is corresponding for the transmission block (ACK) being properly received if its corresponding CC bit is " 1 " for TB bit
TB bit is set to " 1 "；Otherwise (NACK) is set to " 0 ".
For TB bit, illustrate the anti-of the member carrier uplink HARQ feedback mechanism if being " 0 " if its corresponding CC bit
Feedforward information is expressed by the uplink authorization information/Downlink Control Information (DCI0/4) being located on the same Transmission Time Interval, because
This is not necessarily to repeat to indicate on corresponding TB bit；In this case, these bit are utilized to accelerate on corresponding member carrier
The blind examination of uplink authorization information/Downlink Control Information, one of specific implementation are to further reduce or indicate the polymerization of the DCI
Grade (range)；It is specifically defined referring to Tables 1 and 2.
Under 1 PDCCH of table in DCI X transmission block bit assignment rule explanation
Under 2 EPDCCH of table in DCI X transmission block bit assignment rule explanation
Below with reference to specific Application Scenarios-Example, use process to above-mentioned new Downlink Control Information DCI X and its
Technical characterstic is illustrated.
In order to simplify the relationship of HARQ timing, all member carriers are assumed to FDD, or the main member of at least user equipment
Carrier wave is that the PUSCH of FDD and all secondary member carriers is dispatched by main member carrier, the timing of ascending HARQs all in this way
Relationship can follow the sequential relationship in the case of FDD:
Assuming that user equipment 1 has polymerize the PUSCH of 8 uplink member carriers on subframe i, wherein based on member carrier 0
Member carrier, other member carriers are secondary member carrier.Wherein, 0/ member carrier of member carrier, 1/ member carrier 2 supports space
Be multiplexed (i.e. double transmission blocks), in addition 3/ member carrier of member carrier, 4/ member carrier, 5/ member carrier, 6/ member carrier 7 this 5 at
Member's carrier wave is single transmission block, that is to say, that user equipment transmits 11 uplink transmission blocks altogether on subframe i.
According to HARQ sequential relationship, user equipment 1 is known on subframe i+4 should can be in member carrier 0 (main plot)
The specific search space UE search DCI X.Then, user equipment 1 is according to the size=of the C-RNTI and DCI X of oneself
19bits carrys out blind examination DCI X.
After obtaining DCI X, it is assumed that
A) CC_Feedback_List=0 0011011 obtained；Then illustrate 0/ member carrier 1/ of member carrier
Have new data or adaptive retransmission on 2/ member carrier 5 of member carrier, it is specifically any, need further to distinguish blind examination this three
Search space corresponding to a member carrier defines；There is no new data scheduling and adaptive weight on remaining 4 member carrier
It passes, therefore does not just have to blind examination DCI 0/4 again on search space corresponding to this 4 member carriers；
B) TB_Feedback_List=00 01 11 11001 is obtained；Assuming that Downlink Control Information is all carried on
On PDCCH, then the corresponding uplink authorization information of 0/ member carrier of member carrier, 1/ member carrier, 2/ member carrier 5/downlink control is believed
The polymerization grade of breath is respectively 1,2,8,1/4, therefore, behind only need to distinguish blind examination by these specific polymerization grades respectively
DCI 0/4；3/ member carrier of member carrier, 4/ member carrier 7 is to be properly received in remaining 4 member carrier, due to not counting newly
According to scheduling, there is no need to blind examination DCI 0/4；And member carrier 6 is NACK, so non-adaptive sync retransmission is directly triggered,
Without blind examination DCI 0/4.
From above-described embodiment as can be seen that can indicate some user equipment using DCI X mechanism provided by the present invention
Behavior on each active member carrier wave, such as: whether there is new data or adaptive retransmission, if again without new data and
Retransmitting is also non-adaptive re-transmission.If it is there are the member carriers of new data scheduling or adaptive retransmission, then further instruction
More accurate uplink authorization information/Downlink Control Information (i.e. DCI0/4) polymerization grade, to realize more efficient blind examination；If
It, can be disposable as ascending control information if being the member carrier of no new data and re-transmission and non-adaptive re-transmission
Carry the ACK/NACK information of all transmission blocks on all this member carriers.
If not using DCI X mechanism provided by the present invention, the expense increaseing accordingly is as follows:
1) it needs to emit 11 PHICH, in order to avoid the resource contention of this 11 PHICH, needs to dispatch 11 with caution
The transmission block resource allocation of PUSCH；
2) user equipment needs to press all possible polymerization grade on the corresponding specific search space UE of 8 member carriers
Blind examination DCI 0/4.
It should be noted that Downlink Control Information structure provided by above-mentioned DCI X mechanism looks like elongated structure, but
User equipment blind examination is not influenced in fact, because can determine its length in advance for user equipment；Such as: certain user
Equipment has polymerize 8 member carriers on subframe i, wherein 3 member carriers support spatial reuse (i.e. double transmission blocks), in addition 5
A is single transmission block, then the length of DCI X is (8*1+3*2+5*1)=19bits.In the event of length and existing C-RNTI
Scramble Downlink Control Information it is the same in the case where, can be evaded by arranging a kind of bit padding rule.
In addition, resource distribution type and PRB pair number and corresponding scene (case) type for EPDCCH,
This is all known before doing Downlink Control Information blind examination for user equipment, therefore user equipment can be according to transmission block ratio
Special value realizes more small-scale blind examination.
Compared with prior art, Downlink Control Information implementation method provided by the present invention is more than in member carrier number
5 and in the case where supporting cross-carrier scheduling, the feedback that can effectively solve PHICH collision, improve UL HARQ ACK/NACK
The blind examination efficiency of efficiency and Downlink Control Information.
The Downlink Control Information implementation method of optimization ascending HARQ provided by the present invention has been carried out specifically above
It is bright.For those of ordinary skill in the art, it is done under the premise of without departing substantially from true spirit any aobvious
And the change being clear to, the infringement for all weighing composition to the invention patent, corresponding legal liabilities will be undertaken.
