In advance with the data transmission interval time among the UE, be defined as and the identical numerical value of data transmission interval time in the base station.
In specific implementation process, if UE successfully receives data by HS-DSCH, and have ready conditions and feed back (such as: uplink synchronous etc.), then UE sends ACK message by HS-SICH.
If ACK message is received in the base station, then stop to send control signaling and data.
In specific implementation process, UE can also successfully not receive data, and has ready conditions when feeding back, and sends NACK message by HS-SICH to the base station.
UE can also select whether to send ACK message and/or NACK message according to concrete needs.
Wherein, can further include before the step 500:
The base station sends control signaling for the first time by HS-SCCH, after the control signaling sends, according to signaling and data transmission interval time, sends data by HS-DSCH.
In the present embodiment, data re-transmitting number of times and signaling are retransmitted number of times can comprise the number of times that sends for the first time, also can not comprise the number of times that sends for the first time.
Present embodiment can be applied under the enhancing CELL-FACH state of TDD system, utilizes the downlink data transmission of public H-RNTI, perhaps the downlink data transmission under the situation of dedicated H-RNTI and UE uplink loss.
In specific implementation process, utilize the mode of the control signaling bear data re-transmission number of times information among the HS-SCCH to have two kinds:
Mode one: do not change the channel architecture of HS-SCCH, remapped in each territory on the HS-SCCH.
This mode has been cancelled the mapping of HARQ process ID, redundancy versions RV, new data indication NDI, and the vacant 7bits (suspense is the S territory) that comes out is remapped, and wherein the S territory mode of hinting obliquely at again is divided into two kinds of schemes again:
Scheme 1:S territory is hinted obliquely at again and is data re-transmitting number of times (as N, N 〉=1), and the retransmission sequence number of the data of control signaling correspondence, be that retransmission sequence number is (as RSN (retransmission sequence number), and the time interval between adjacent twice HS-DSCH transmission, i.e. data transmission interval time n RSN 〉=0),
HS-DSCH(n
HS-DSCH〉=0, be unit with TTI (Transmission Time Interval)), UE can derive redundancy versions RV by RSN like this, perhaps adopts the predefined mode UE redundancy versions RV that gives advance notice.
Scheme 2:S territory hint obliquely at again for remaining data re-transmission number of times (as N_surplus, N_surplus 〉=1, N_surplus=N-RSN), and the time interval between adjacent twice HS-DSCH transmission be data transmission interval time n
HS-DSCH(n
HS-DSCH〉=U is a unit with TTI), scheme can only adopt the predefined mode UE redundancy versions RV that gives advance notice like this;
Wherein, also can there be other multiple indicating modes in the time interval in above-mentioned two kinds of schemes between adjacent twice HS-DSCH transmission except by the HS-SCCH indication, as adopting when the RRC connection is set up by high-level signaling notice or predefined mode etc.
Mode after remapping in each territory on the HS-SCCH, as shown in table 2,
| The content of beared information | Original mapping mode | This enforcement mapping mode | |
| The indication of TFRI resource | Time-slot code channel distributes | Time slot bitmap=5bits, StartCode=4bits, EndCode=4bits; | Time slot bitmap=5bits; Utilize EndCode (4bits) to indicate initial code channel, utilize StartCode (4bits) to indicate initial code channel, StartCode＞EndCode; |
| Modulation system | 1bit：0-QPSK，1-16-QAM； | ||
| The transmission block size | 6bits: index value; | ||
| HARQ information | HARQ ID | 3bits: span 0-7, concurrent process mostly is 8 most on the transmission channel | The mode that this part 7bits remaps has two kinds of schemes, depends on the difference of subscheme, and redundancy versions RV can |
| Incremental redundancy version | 3bits: indication r, s, b parameter |
| The new data indication | 1bit: indication is new data or data retransmission | To derive, perhaps adopt predefined mode by RSN | |
| HCSN | 3bits: the block error rate BLER that is used to add up the HS-SCCH channel in the power control system process | ||
| H-RNTI | UE ID indicates | 16bits: the affiliated UE of sign control signaling | |
| SS | The uplink synchronous command word | 2bits: be used to keep the HS-SICH uplink synchronous | |
| TPC | The uplink power control command word | 2bits: the closed-loop power control that is used for HS-SICH |
Table 2
This structure that does not change HS-SCCH, the mode that is remapped in each territory on the HS-SCCH, because the transformat of HS-SCCH and the HS-SCCH transformat in the background technology are consistent, avoid UE that the transformat of multiple HS-SCCH channel is carried out the blind Detecting operation.
After UE receives HS-SCCH after pass-through mode 1 changes according to original transformat, by the StartCode＞EndCode among the TFRI, judgement is the control signaling of repeated retransmission mechanism, EndCode is interpreted as the initial code channel of data re-transmission resource, StartCode is interpreted as retransmitting the termination code channel of resource, in conjunction with time slot allocation information, on relevant code track, receive the data of (N-RSN or N_surplus) inferior repeated retransmission continuously.
Mode two: change the channel architecture of HS-SCCH, optimize the control signaling of HS-SCCH carrying.
Defined the channel architecture of a kind of new HS-SCCH in this mode, as shown in table 3,
| Resource allocation indication (time slot, code channel information) | MCS | TBS Index | N | RSN | n HS-DSCH | HCSN | UE ID |
| Or N_surplus |
Table 3
This mode reduces the bit number of beared information on the HS-SCCH channel, as time-slot code channel resource allocation information, TB Size Index, thereby can save the control expense, control signaling on the channel architecture of new HS-SCCH has: the time interval between iterative transfer times N, retransmission sequence number RSN (or remaining iterative transfer times N_surplus), the adjacent twice HS-DSCH transmission, i.e. data transmission interval time n
HS-DSCH(is unit with TTI), HCSN (the circulation sequence number of HS-SCCH), UE ID, conversion (a kind of mode that table 3 is just realized, the modification of other a lot of HS-SCCH structures in addition) can be carried out according to concrete needs in the position at the bit number in each territory and mapping place thereof.Certainly, data transmission interval time n
HS-DSCHCan in HS-SCCH, not indicate yet, can adopt other modes to indicate, such as adopting when the RRC connection is set up by high-level signaling notice or predefined mode etc.
As shown in Figure 6, in the embodiment of the invention HSDPA shared channel timing relationship schematic diagram, signaling and data transmission interval time be less than data transmission interval time, the data re-transmitting times N, signaling repeats to send number of times M, and data re-transmitting number of times and signaling are retransmitted number of times and comprised the number of times that sends for the first time.
Certainly, signaling and data transmission interval time also can be more than or equal to data transmission interval time.
The base station sends control signaling by HS-SCCH as required, through n
HS-SCCH, promptly after signaling and the data transmission interval time, at T1 constantly, send data by HS-DSCH.
T2 is that the moment that sends data, (to send data for the first time was benchmark constantly to TN constantly, determine according to the data break time), T2 ' to the TN ' moment be moment that possible send control signaling (definite) according to signaling and data break time and data break time.
The base station selects (M-1) individual moment to send control signaling (N-1) the individual moment from T2 ' to TN '.
As shown in Figure 7, the embodiment of the invention adopts the special shape of HS-SCCH to comprise the following steps: as the method that retransmits sign
Wherein, data re-transmitting number of times and signaling are retransmitted the number of times that number of times comprises that send the first time.
Wherein because data re-transmitting number of times and signaling are retransmitted number of times and are comprised the number of times that sends for the first time in the present embodiment, so the base station follow-up (M-1) individual moment carry out HS-SCCH repeat send.
What step 704, UE judged the HS-SCCH carrying is the control signaling of traditional approach, then carries out the HSDPA operation in the conventional mode.
Wherein, can further include between step 702 and the step 703:
Whether UE received identical control information before continuing to judge by the data re-transmission number of times information in the control signaling, if then UE only need follow the control information that receives for the first time and receives; Otherwise, receive according to the current control information that receives.
