Step 706:ENB is received after rear NACK message, and the data are resend to the trunking；Step 707:Trunking receives the data of the UE from repeated link, and can decode the data；Step 708:The decoded data are sent to UE by trunking.
Wherein, in this embodiment, step 703 and step 704 in no particular order order, can also carry out simultaneously, using the present embodiment order as preferred embodiment.
Wherein, UE extends the time of itself state of activation after the message including DRX command 1 is received, and intercepts whether PDCCH has data transmission, that is, after DRX command 1 are received, according to the DRX command 1, the time of the UE states of activation can be extended, can also first resting state for a period of time, state of activation is being reentered, in any way, its purpose is all untill listening to the head biography instructions of the data on PDCCH.Its concrete implementation process refers to Fig. 8 to Figure 11.
As shown in figure 8, being a kind of schematic diagram of the time of extension UE states of activation in the embodiment of the present invention；In the Fig. 8, UE is during onduration, receive after the message that trunking sends the orders of DRX command 1, then extend the time of active states, show (Decoded PDCCH for new transmation) until listening to the head biography ability purports of the data on PDCCH channels.
Also referring to Fig. 9, a kind of exemplary application map of the time to extend UE states of activation in the embodiment of the present invention；As shown in Figure 9, trunking sends the message of DRX command 1 to UE, UE is during onduration, trunking is received to send after the message of DRX command 1, start timer timerA, and extend the time of active states all in active states before timer A time-out, pass instruction until listening to the head of the data on PDCCH channels（That is, UE thinks that packet can be issued within (0, timer A) this period to Decoded PDCCH for new transmission.If timer A timer expiries or after UE receives packet, UE enters resting state.Wherein timer timerA span may be configured as 15 subframes.In LTE system, 1 subframe=lms, then 15 subframes=15ms.Can be so that timer A duration scope be limited in（0,15ms) in the range of.
As shown in Figure 10, be another extension UE states of activation in the embodiment of the present invention time schematic diagram；In the Figure 10, UE is during onduration, receive trunking to send after the message for carrying the orders of DRX command 1, UE is first just according to needing (re-transmission time of such as repeated link) to enter resting state, after sleeping（The time can be one or several RTT times, be controlled by timer timerB) active states are entered back into, pass instruction until listening to the head of the data on PDCCH.
Figure 11 is also referred to, is another application of the time of extension UE states of activation in the embodiment of the present invention
Instance graph；As shown in figure 11, when trunking to UE sends the message of DRX command 1, UE is received after the message of f ' J DRX command 1, start timer timerB, and the front and rear startup timer A in timer B ultrasound, and all in active states during timer A, that is, extend the time of active states, instruction is passed until listening to the head of the data on PDCCH channels（Decoded PDCCH for new transmation ).That is, i.e. UE thinks that packet can be reached within (timer B, timer Β+timer A) this period.When timer A timer expiries or UE receive packet, UE enters resting state.Wherein, timer timerA span may be configured as 5 subframes, and timer timer B span may be configured as 10 subframes.In LTE system, 1 subframe=lms then can make timer A duration be set to 5ms, timerB duration is set to 10ms.In fact, timer A and timer B duration value can be（Lms, 100ms) in the range of, it is preferred that duration scope can be（Lms, 18ms).
The situation of time based on above-mentioned extension UE states of activation, in embodiments of the present invention, assuming that the frame structure introduced in long evolving system after trunking is as shown in figure 12, in the Figure 12, dotted line with arrow represents other data or signaling transmitted by the frame structure, and the present embodiment is no longer described in detail.The detailed process of the communication means of this in the embodiment of the present invention includes：
1st, eNB sends packet, but the packet loading error occurring in the 0th subframe to Relay；
2nd, trunking feeds back non-acknowledgement message NACK in the 4th subframe to eNB;
3rd, trunking sends the message of DRX command 1 in the 6th subframe to UE；UE is received after the message, performs the associative operation of the message of DRX command 1：
A kind of situation is：UE is received after the message of DRX command 1, starts timer（Timer) A, and all in active states before timer A time-out.When timer A time-out/when UE receives packet, UE enters resting state.Wherein, the span of timerA duration can be（Lms, 100ms), span preferably is（Lms, 18ms), timerA duration is for example taken as 18ms (i.e. 18 subframes）, i.e., carry out data transmission within the 18ms after receiving the message of DRX command 1.
Another situation is：When trunking is to the message of UE transmission DRX command 1, UE is received
After the message of DRX command 1, start timer B, and in timer B ultrasound after start timer A, and during timer A be in active states.When timer A time-out/when UE receives packet, UE enters resting state.Wherein, timerA duration may be configured as 10ms (10 subframes）, timer B duration may be configured as 8ms (8 subframes）, i.e., 8ms to the 18ms after the message of DRX command 1 is received
Within carry out data transmission.
4th, eNB retransmits the packet in the 0th subframe of the second frame；
5th, trunking is received after the packet, and the packet is sent to UE in the 6th subframe of the second frame.As shown in A points in Figure 12.
