Step 301, base station (eNode B) send uplink resource assignment signaling (UL Grant) to mobile terminal (UE).
Wherein UL Grant carries the positional information and the modulation system etc. that send upstream data.
Step 302, UE send data according to the information of the UL Grant receiving in particular moment, and particular moment is that eNode B issues 4 TTI moment after UL Grant here.
Step 303, eNode B successfully receive the data that UE sends, and pass through PHICH channel to UE feeding back ACK.
Wherein, step 303 need to have two preconditions, and (1) issues the ACK moment at eNode B to UE and do not dispatch new data; (2) ACK that this time eNode B issues is not the ACK of UE to the last retransmission feedback of UE.
Particularly, if owing to issuing the ACK moment at eNode B to UE, eNode B dispatches new data, stipulate according to agreement, send new data to base station at 4TTI moment UE, the ACK issuing to UE at 8TTI moment eNode B, can be thought the feedback information for new data by UE, so precondition (1) is set, for guaranteeing that the ACK issuing to UE at 8TTI moment eNode B is the feedback of data retransmission during for likely demodulation mistake of UE here; In addition, if because UE has reached maximum times, eNode B is to this last retransmission feedback ACK, even if UE is by ACK demodulation mistake like this, UE can not resend data to eNode B, and precondition (2) is therefore set here.
The PHICH information that step 304, UE send eNode B is carried out demodulation, when ACK is demodulated into NACK by UE, is receiving that 4 TTI moment that eNode B sends after ACK resend data to eNode B.
Under two preconditions in step 303, after step 303 finishes, in prior art, eNode B can think and completed the feedback to all reception data, even at this moment UE demodulation mistake in step 304, resend data to eNode B, eNode B can not send feedback information to these data, and is originally implemented in the rear execution step 305 of step 304.
Step 305, in step 303 eNode B to UE send the ACK moment through 8 TTI, eNode B sends for the ACK that resends data in step 304, so that UE carries out demodulation again to this ACK by PHICH channel to UE again.
By above-mentioned steps, eNode B sends ACK for same data twice to UE, is demodulated to power to promote UE.
ENode B successfully receives the data that UE sends, to UE feeding back ACK, now UE is likely demodulated into NACK by the ACK of eNode B feedback, the present embodiment by the time that eNode B issues ACK to UE through 8 TTI again to UE send on the ACK of data, thereby promote UE and be demodulated to power, the correctness that guarantees critical workflow signaling, the method for this enforcement is specially adapted to guarantee the scene of PHICH accuracy, such as the signalings such as access, switching are paid.
Fig. 4 is the flow chart of the fault-tolerance approach embodiment tetra-of PHICH channel transmission information of the present invention, and the present embodiment uses the technical scheme of embodiment tri-, this scheme is applied to user and accesses scene, and as shown in Figure 4, the method for the present embodiment can comprise:
Step 401, eNode B send UL Grant to UE.
Step 402, UE send RRC Connection Request(MSG3 to eNode B).
Step 403, eNode B correctly receive information, by PHICH feeding back ACK.
The ACK of eNode B feedback is demodulated into NACK by step 404, UE, and UE thinks that eNodeB does not receive MSG3, can retransmit MSG3 to eNode B.
Step 405, eNode B again to UE are issuing ACK through 8 TTI by PHICH for the first time after UE feeding back ACK.
In prior art, if UE receives the ACK of eNode B for the MSG3 feedback of its transmission, ACK is demodulated into NACK, UE thinks that eNode B does not receive MSG3, it can resend MSG3, and eNode B sends RRC Connection Setup(MSG4 to UE after UE feeding back ACK), now due to UE think eNode B do not receive MSG3 UE receive MSG4 and can't process, but repeat to send MSG3, can cause user's access failure, the present embodiment again to UE is issuing ACK through 8 TTI by PHICH for the first time by eNode B after UE feeding back ACK, even if ACK is demodulated into NACK by UE so for the first time, the probability that the second demodulation is correct also can increase greatly, thereby realize the success rate that promotes access process, guarantee the correctness of critical workflow signaling, and reduce the Message Time Delay in access procedure.
