Description
Technical field
The present invention relates to the technology of communication system, particularly to mandate and the HARQ transmission method of a kind of PUSCH.
Background technology
At Release10(Rel-10) in, introduce carrier aggregation concept with support broader bandwidth transmission, i.e. two or more
Carrier wave is grouped together in together, to support the transmission more than 20MHz of the LTE-A transmission bandwidth.TDD for the carrier aggregation of Rel-10
Scene, (intra-band) scene in a band support, this frequency range (band) is the spendable nothing that International Telecommunication Union determines
Line resource frequency spectrum resource, produces serious interference if using different up-downgoing proportionings can make during up and descending transmitting-receiving, because of
Each member carrier (component carrier) of this polymerization uses identical TDD up-downgoing proportioning, as it is shown in figure 1, up-downgoing
Sub-frame configuration is as shown in table 1.In Rel-10, in order to reduce the interference to control channel of the isomery scene, introduce intersection carrier wave
The control channel of scheduling concepts, i.e. a carrier wave can be by another carriers carry, by before Downlink Control Information (DCI)
Adding 3bit carrier wave instructions field (CIF) and distinguish the carrier wave being scheduled, as in figure 2 it is shown, CC0 is scheduling carrier wave, CC1 and CC2 is quilt
Scheduling carrier wave, the PUSCH on CC0 scheduling CC1 and CC2 carrier wave.In Release11, it is introduced into (inter-band) between frequency range carry
Ripple is polymerized, to reach the more flexible utilization of resources.
Table 1
In Rel-8/9/10, a part of resource of PHICH channel occupancy PDCCH, as it is shown on figure 3, may in Rel-11
Introduce and strengthen PHICH(i.e. e-PHICH) channel, this channel is placed in PDSCH region.
In Rel-11 carrier aggregation, different frequency range may use different up-downgoing proportionings.When different frequency range uses
During different up-downgoing proportioning, it is possible that the scene that sub-frame of uplink conflicts with descending sub frame, as shown in oval in Fig. 4.
This situation can affect the scheduling of intersection carrier wave, and the HARQ of PDSCH and PUSCH, it is therefore desirable to amendment is to adapt to new field
Scape.Also defining the concept of Cell in Rel-10, each Cell comprises a descending CC and the up CC being optionally connected.
In Rel-8/9/10, having 0-6 totally seven kinds of subframe proportionings for TDD, wherein for sub-frame configuration 0 and 6, it is up
Transmission Loop Round Trip Time (RTT, round-trip time) is not 10ms.For other 5ms switching cycles configuration (configuration 1 and 2) and
10ms switching cycle configuration (configuration 3,4,5), the RTT time is all 10ms.What wherein RTT referred to sends out from a PUSCH transmission
Begin, send, to next time, the time interval that this PUSCH retransmits.
When PUSCH is carried out uplink authorization, need to notify UE by descending sub frame.And when intersecting carrier dispatching, when
When scheduling Cell is non-10ms RTT, if certain conflict subframe is sub-frame of uplink at scheduling Cell, then be positioned on scheduling Cell should
Conflict subframe cannot send the uplink authorization of the Cell that is scheduled.When being mixed with 10ms RTT and non-10msRTT in configuration simultaneously,
The HARQ process of PUSCH does not has specification.
Specifically, a HARQ process refers to that base station scheduling carries out a data transfer, then to receiving ACK/NACK letter
Breath, HARQ process number refers to concurrent HARQ number.
In a HARQ process, after once transmission sends, need a length of RTT waited could determine to transmit next time
It is transmission new data, is also by the re-transmission of legacy data.During this period of time, eNB/UE certainly can not stop transmission and in vain
Wait.Therefore, it is necessary to initiate other parallel HARQ processes, to make full use of time-domain resource.

Detailed description of the invention
For making the purpose of the present invention, technological means and advantage clearer, below in conjunction with accompanying drawing the present invention done into
One step describes in detail.
When Rel-11 intersects carrier dispatching, when proportioning has 0 or 6, owing to the time of RTT changes to enter PUSCH
Journey has an impact, and when the present invention provides TDD difference band different ratio, the HARQ of the PUSCH of RTT non-10ms intersection carrier dispatching enters
Journey designs.In the present invention the Cell of carrying scheduling authorization being called dispatching Cell, scheduling authorization transmits on other Cell
Cell is referred to as the Cell that is scheduled.
When being different up-downgoing proportioning combinations for scheduling Cell and the Cell that is scheduled separately below, provide the present invention's
PUSCH authorizes and HARQ transmission method.Simple for describing, in the example shown, above for scheduling Cell, below for being scheduled
Cell。
(1) scheduling Cell is RTT 10ms, and the Cell that is scheduled is the non-10ms of RTT, in other words, on the TDD of scheduling Cell
Descending proportioning is any one in configuration 1～5, and the TDD uplink-downlink configuration of the Cell that is scheduled is configuration 0 or 6
Combining for this uplink-downlink configuration, the present invention provides three kinds of PUSCH and authorizes and HARQ transmission method, separately below
Introduce.
Method (1):
For the non conflicting subframe of the Cell that is scheduled, by process and the timing relationship of corresponding process of scheduling Cell, adjusting
The PUSCH carrying out these non conflicting subframes on degree Cell authorizes and HARQ transmission；
For the conflict subframe of the Cell that is scheduled, redefine PUSCH HARQ process and timing relationship thereof, and ensure right
PUSCH HARQ process RTT in each definition is 10ms；According to the process redefined and timing relationship, on scheduling Cell
The PUSCH carrying out these conflict subframes authorizes and HARQ transmission.
In the manner described above, for non conflicting subframe, its process is identical with the Cell that is scheduled with timing relationship, the most accordingly
The RTT mono-of process is set to 10ms.For conflict subframe, the RTT of each process is also designed as 10ms.Visible, according to this method,
The RTT of each PUSCH HARQ process is 10ms such that it is able to ensure that the mandate of PUSCH and HARQ transmission are normally carried out.
By scheduling Cell be configuration 1, the Cell that is scheduled for configuration 0 as a example by, as it is shown in figure 5, give configuration the showing of 0 correspondence
There are HARQ process and timing relationship, the existing HARQ process of configuration 1 correspondence and timing relationship thereof and the carrier dispatching pair that intersects
HARQ process and timing relationship thereof in the present invention answered.Wherein, the descending sub frame of some point represents under corresponding configuration, this descending son
Frame cannot be used for transmitting PHICH；Other descending sub frames represent under corresponding configuration, and this descending sub frame may be used for transmitting PHICH
And uplink authorization；1, the numerals such as 2,3,4 and a, b represent PUSCH HARQ process numbering (represent it is to illustrate 1 with a, b here, 2 etc.
The design philosophy of digitized representation process, can essentially sort together), the Pn such as P1, P2, P3, P4, Pa, Pb represents process n
PHICH position, the Gn such as G1, G2, G3, G4, Ga, Gb represents the uplink authorization position of process n.As Fig. 5 is given in next two columns
Intersect shown in the new process of carrier dispatching and timing relationship thereof, in this process and timing relationship, for non conflicting subframe, i.e. son
Frame 2,3,7,8, its process and timing relationship are identical with process and the timing relationship of identical subframe in scheduling Cell, utilize in the drawings
N, Pn and Gn represent；For conflict subframe, i.e. subframe 4 and subframe 9, redefined process, utilize in the drawings a, b, Pa, Pb,
Ga, Gb represent, specifically, uplink authorization corresponding to the process of subframe 4 in subframe 0, corresponding PHICH in the subframe 0 of next frame,
The uplink authorization that the process of subframe 9 is corresponding in the subframe 5 of next frame, utilizes arrow table at subframe 5, corresponding PHICH in Figure 5
Show.From above-mentioned Fig. 5, for intersecting carrier dispatching, non conflicting subframe definition 4 HARQ processes, conflict subframe definition 2
Individual HARQ process, includes altogether 6 HARQ processes.
In Figure 5, for subframe 4, its uplink authorization and PHICH are in subframe 0, and subframe 0 is to use in configuration 1
In the transmission uplink authorization of PUSCH and PHICH, say, that the most corresponding according to the timing relationship PUSCH of definition
PHICH subframe, for this situation, utilizes DCI to authorize and triggers re-transmission or use the e-PHICH triggering being positioned on PDSCH to retransmit.
Fig. 6 give scheduling Cell be configuration 2, the Cell that is scheduled intersect carrier dispatching corresponding new when being configuration 0
PUSCH HARQ process and timing relationship schematic diagram.As shown in Figure 6, for non conflicting subframe, still entering according to scheduling Cell
Journey and timing relationship are carried out；For conflict subframe, except subframe 4 arranges identical with Fig. 5 with the HARQ process of 9 and timing relationship thereof
Outward, the newest corresponding new PUSCH HARQ process of definition subframe 3, i.e. process d, the uplink authorization of its correspondence and HARQ transmission
In subframe 9, the newly corresponding new PUSCH HARQ process of definition subframe 8, i.e. process c, the uplink authorization of its correspondence and
HARQ transmission is in subframe 4.Wherein, process and timing relationship for clearly showing that conflict subframe are arranged, by right to subframe 4 and subframe 9
The timing relationship answered utilizes new timing and authorizes the arrow line below form to represent, by subframe 3 and the timing of subframe 8 correspondence
Relation utilizes the arrow line between configuration 2 and configuration 0 to represent.From above-mentioned, for intersecting carrier dispatching, define 6 altogether
Process.As hereinbefore, in the process of definition, cannot be used in the subframe position that (i.e. PHICH) is corresponding passing when PUSCH retransmits
During defeated PHICH, utilize DCI to authorize and trigger re-transmission or use the e-PHICH triggering being positioned on PDSCH to retransmit.
Fig. 7 and Fig. 8 sets forth be scheduled Cell for configuration 6 scheduling Cell be configuration 1, the Cell that is scheduled be configuration 6
Scheduling Cell is process and the timing relationship schematic diagram of configuration 2.Concrete meaning is same as described above, the most just repeats no more.Above-mentioned
About the timing relationship design of conflict subframe in Fig. 5～Fig. 8, it is only an example, it would however also be possible to employ other timing relationship, but
Ensure that the RTT of corresponding process is 10ms, simultaneously need to follow PUSCH HARQ process and the general standard of timing relationship setting,
Such as: the time interval of n to Pn/Gn and Pn/Gn to n is greater than or equal to 4 subframes, shorten between twice PUSCH transmission as far as possible
Time interval.
Method (2):
For the PUSCH of the Cell non conflicting subframe that is scheduled, according to the PUSCH HARQ process of scheduling Cell and each
The timing relationship of HARQ process, carries out mandate and the HARQ transmission of the PUSCH of corresponding subframe on scheduling Cell；
For the PUSCH of the Cell conflict subframe that is scheduled, close this conflict subframe, say, that not scheduling conflict subframe.
This method (2) is simple, little on specification impact, but the cell ascending resource that is scheduled is limited, and utilization rate is low.
Fig. 9 for by scheduling Cell be configuration 1, be scheduled Cell for configuration 0 as a example by according to method (2) carry out intersect carrier wave adjust
PUSCH HARQ process and timing relationship schematic diagram during the transmission spent.
Method (3):
According to PUSCH HARQ process and the timing relationship of each HARQ process of the Cell that is scheduled, on scheduling Cell
Carry out being scheduled the mandate of PUSCH on Cell and HARQ transmission.It is to say, by the timing of the Cell that is scheduled, adjust corresponding
Transmitting mandate and the PHICH of PUSCH on the Cell that is scheduled on degree Cell, process is constant.This method is simple, it is not necessary to define new
Process, ascending resource can make full use of, but the subframe sending uplink authorization is likely not to have corresponding PHICH resource.
Figure 10 for by scheduling Cell be configuration 1, be scheduled Cell for configuration 0 as a example by according to method (3) carry out intersect carrier wave
PUSCH HARQ process and timing relationship schematic diagram during the transmission dispatched.
(2) scheduling Cell be the non-10ms of RTT, the Cell that is scheduled be RTT 10ms, in other words, scheduling Cell TDD on
Descending proportioning is configuration 0 or 6, and the TDD uplink-downlink configuration of the Cell that is scheduled is any one in configuration 1～5
Combining for this uplink-downlink configuration, the present invention provides two kinds of PUSCH and authorizes and HARQ transmission method, separately below
Introduce.
Method (1):
With reference to the timing of scheduling Cell, define new PUSCH HARQ process.Specifically, according to scheduling Cell in adjusted
Degree Cell is all the timing relationship of each sub-frame of uplink of sub-frame of uplink, arranges in the Cell that is scheduled PUSCH HARQ on sub-frame of uplink
Process and the timing relationship of corresponding process, and according to the timing relationship of this setting, the Cell that carries out being scheduled on scheduling Cell is each
The mandate of individual sub-frame of uplink PUSCH and HARQ transmission.Wherein, HARQ process on arbitrary sub-frame of uplink in the Cell that is scheduled of setting
Timing relationship, with scheduling Cell on identical sub-frame of uplink the timing relationship of HARQ process identical.Here timed-shutoff means
Time of n to Pn/Gn, do not include the time interval of Pn/Gn to n.When defining new process, as it was previously stated, need to follow
The general standard that PUSCH HARQ process and timing relationship are arranged, such as: the time interval of n to Pn/Gn and Pn/Gn to n wants big
In or equal to 4 subframes.
By scheduling Cell be configuration 0, be scheduled Cell for configuration 1 as a example by, as shown in figure 11, last group form represent new
The PUSCH HARQ process of definition and corresponding timing relationship thereof.Time interval in view of Pn/Gn to n is greater than or equal to 4
Individual subframe, and shorten the time interval between retransmitting, in 5 processes that have been scheduled defined in Cell (if only definition 4 is entered as far as possible
Journey, then the re-transmission of process 2 is positioned at subframe 3, and is only separated by 2 subframes between this re-transmission and last PHICH, undesirable).Its
In, for the process of each new definition, this process and the time interval of its PHICH are and identical subframe corresponding in scheduling Cell
Time interval is identical, say, that the time of n to Pn/Gn is identical.And the time interval for Pn/Gn to n can be with scheduling
Difference in Cell.Such as, for the HARQ process 2 of new definition, be positioned in the subframe 3 of the first radio frames, its timing relationship P1 and
G1 is identical with mandate and the PHICH position of HARQ process in scheduling Cell subframe 2, is i.e. positioned in the subframe 0 of the second radio frames.?
After transferring the data of 5 processes, at each sub-frame of uplink following closely, it is used for successively retransmitting (or new data transmission) definition
5 process data.Based on this, the re-transmission (or new data) of HARQ process 2 is positioned in the subframe 7 of the second radio frames, with scheduling
In Cell, the re-transmission position of HARQ process 2 is different.For the HARQ process 2 of this re-transmission, identical with its position in scheduling Cell
Subframe is the subframe 7 of the second radio frames, and what this subframe 7 carried is the data of HARQ process 3, therefore, and weight on the Cell that is scheduled
The PHICH of HARQ process 2 correspondence passed and uplink authorization, it should with PHICH and the uplink authorization dispatching HARQ process 3 on Cell
Position is identical, is i.e. positioned in the subframe 1 of the 3rd radio frames.For each subframe follow-up, determine each process according to above-mentioned rule
Re-transmission and PHICH, the position of uplink authorization.
