The embodiment of the invention discloses the data receive method under a kind of repeat ACK/NACK mechanism, this method utilizes pre-configured repeating feedback mechanism RRT Timer to carry out Data Receiving.
Described repeating feedback mechanism RRT Timer is configured to: the time of the last feeding back ACK/NACK of conventional RRT+ and the difference of the time of feeding back ACK/NACK first.
Corresponding different systems, the concrete configuration of above-mentioned RRT Timer are also different, are that example describes with LTE TDD system and LTE FDD system below:
1, at LTE TDD system
The frame structure of LTE TDD system as shown in Figure 2, each radio frames is made of two fields (Half-frame), each field length is 5ms, form by 5 subframes (Subframe), each subframe lengths is 1ms, subframe 1 and subframe 6 comprise three special time slots (DwPTS, GP and UpPTS) in a radio frames, and other subframes all have two normal time slots to constitute, and each normal time slot is 0.5ms.
LTE TDD system definition 7 kinds of uplink-downlink configuration modes (label is respectively 0-6) as shown in table 1:
Table 1
Wherein: D represents descending, and U represents up, and S represents to comprise the subframe of special time slot.
And which sub-frame of uplink feedback is LTE TDD system also stipulated the data of which descending sub frame transmission in, and the corresponding relation of regulation sub-frame of uplink and descending sub frame is as shown in table 2:
Table 2
Wherein: TBD is To Be Decide, promptly represents character to be determined.
As shown in table 2, subframe 2 is a sub-frame of uplink, its corresponding descending sub frame is the 8th, 7,6,4 subframe before this subframe 2, means that the downlink transfer of the 8th, 7,6,4 subframe before this subframe 2 (also i.e. subframe 4,5,6,8 in the previous radio frames of this subframe place radio frames) is all fed back in this subframe 2.
When the conventional RRT Timer of configuration, need to consider the interval between downlink data sending time slots and the ascending time slot that sends feedback, that is: the descending sub frame of transmission data and the current interval that is used for these data are carried out the sub-frame of uplink that ACK/NACK feeds back.
Suppose: the downlink data transmission time is t1 (generally being fixed as 1ms), the descending sub frame of transmission data and the current t2 that is spaced apart that is used for these data are carried out sub-frame of uplink that ACK/NACK feeds back, and the time delay that network side carries out data processing is t3, then:
Conventional RRT Timer=t1+t2+t3.
The embodiment of the invention determines to send the number of repetition of ACK/NACK feedback under repeat ACK/NACK feedback mechanism, and then determines to repeat to send the time of ACK/NACK feedback cost.And represent to repeat to send time of ACK/NACK feedback cost with the moment of last transmission ACK/NACK feedback and the difference in the moment that sends the ACK/NACK feedback first.
The difference of supposing this last ACK/NACK of the transmission moment of feeding back and moment that sends the ACK/NACK feedback first is t4, then repeating feedback mechanism RRT Timer=RRT Timer+t4, that is: repeating feedback mechanism RRT Timer=t1+t2+t3+t4.
The number of repetition that sends the ACK/NACK feedback is by the high level configuration, and its numerical value can be 2,4,6 or reserved (retention).
For example: when number of repetition is 4, and feedback is in the 3rd subframe for the first time, and feedback is in the 4th subframe for the second time, and the 3rd feedback is in the 5th subframe, the 4th feedback when the 6th subframe, the conventional RRT+3 of the conventional RRT+6-3=of repeating feedback mechanism RRTTimer=.

In the LTE FDD system, the downlink data transmission time generally is fixed as 1ms, and UE handles time of downlink data and eNB and handles feedback and also organize the time of data retransmission to be 3ms, and UE sends the time of conventional ACK/NACK feedback and is fixed as 1ms.Therefore, conventional RRT Timer is configured to 8m.
Consider the influence of repeat ACK/NACK feedback, repeating feedback mechanism RRT Timer is configured to: the time of the last feeding back ACK/NACK of 8ms+ and the difference of the time of feeding back ACK/NACK first.
No matter need to prove, still be LTE TDD system for LTE FDD system, comprises in repeat ACK/NACK feedback because conflict and the feedback of cancellation.
The specific implementation process of present embodiment may further comprise the steps as shown in Figure 3:
Step S31, UE receive the downlink data from network side, and carry out timing.
Step S32, judge whether timing arrives repeating feedback mechanism RRT Timer, if enter step S33; Otherwise, return step S32;
Step S33-step S34, monitor PDCCH, and judge whether to have descending control command at this UE, if, then enter step S35, otherwise, step S333 returned;
Step S35, obtain this descending control command, and according to this descending control command downlink data receiving.
After obtaining descending control command, according to the downlink data of demodulates information eNB such as frequency resource position in this descending control command and MCS transmission.
The embodiment of the invention has taken into full account the time delay that repeat ACK/the NACK feedback causes, RTT timer is reconfigured, thereby make UE can determine to monitor the opportunity of PDCCH, avoided too early monitoring PDCCH and cause power resource waste, reach purpose of power saving.
In addition, under UE configuration DRX situation, can guarantee normally carrying out of network side traffic control so that UE can in time monitor PDCCH when network side is dispatched.
