Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to a kind of realization discontinuous receiving method and device.
Background technology
At LTE (Long Term Evolution, Long Term Evolution) in the system, for the energy of saving UE (portable terminal), the time that increases the UE standby, introduced DRX (Discontinuous Reception, discontinuous reception) mechanism: promptly be in connection status following time at UE, the control channel of discontinuous monitoring eNB (base station), but the monitoring control channel that is interrupted, its process is as shown in Figure 1; Time period of On duration (monitor period) expression UE monitoring control channel wherein, during the radio-frequency channel open and monitoring control channel continuously; And outside the On duration At All Other Times, UE is in the Sleep state, its radio frequency link will be closed, to reach purpose of power saving; And (Cycle) periodically appears in On Duration, and the concrete cycle is realized by the eNB configuration.
For specific implementation DRX operation, LTE has designed multiple timer:
Inactivity Timer (non-activationary time timer): when receiving the control signaling of HARQ (mixing automatic repeat requests) initial transmission during On duration, UE opens this timer, before this timer expiry, the continuous monitoring control channel of UE; If before Inactivity Timer is overtime, UE receives the control signaling of HARQ initial transmission, will stop and restart Inactivity Timer;
RTT Timer (Round-Trip Time, two-way time timer): be only applicable to DL (down link); When UE receives the control signaling of HARQ re-transmission, open this timer; Still decoding is unsuccessful if the data in the corresponding HARQ instance process are after preceding HARQ transmission, and then behind RTT Timer timer expiry, UE opens Retransmission Timer; If the data in the corresponding HARQ instance process are decoded successfully in preceding HARQ transmission back, then behind RTT Timer timer expiry, UE does not start Retransmission Timer;
Retransmission Timer (retransmission timer): during Retransmission Timer, the UE monitoring control channel is waited for the re-transmission of corresponding HARQ instance process;
The correlation exemplary plot that comprises the DRX course of work of above-mentioned timer and each timer is an example with two processes as shown in Figure 2:
Process 1: t1 during on duration constantly, eNB has dispatched the initial transmission at process 1, UE opens Inactivity Timer and to deserved RTT Timer1; Because the decoding of the initial transmission of Process 1 is unsuccessful, after RTT Timer was overtime, UE had opened Retransmission Timer1;
In the t3 moment before Retransmission timer1 is overtime, UE has received the re-transmission at Process 1, then stop Retransmission Timer1, and open RTT Timer1; After RTT Timer1 was overtime, UE started Retransmission Timer1 equally;
In the t5 moment before Retransmission Timer1 is overtime, eNB has continued to dispatch the re-transmission of Process 1, so Retransmission Timer1 is terminated, starts RTT Timer1 simultaneously.
Before RTT Timer1 was overtime, UE was to the success of the data decode among the Process 1, so to the eNB feeding back ACK, after RTT Timer1 is overtime, do not restart Retransmission Timer1.
In the process 2:t2 moment, eNB has dispatched the initial transmission at Process 2, and Inactivity Timer is restarted, and opens the RTT Timer2 at Process 2 simultaneously; After RTT Timer2 was overtime, the success because the initial transmission of Process 2 is not decoded was so UE opens Retransmission Timer2;
In the t4 moment before Retransmission Timer2 is overtime, eNB has dispatched the re-transmission of Process 2, so UE stops Retransmission Timer2, opens RTT Timer2;
Before RTT Timer2 was overtime, UE was to the success of the data decode among the Process 2, so to the eNB feeding back ACK, after RTT Timer2 is overtime, do not restart Retransmission Timer2 simultaneously.
From the course of work of above-mentioned DRX as can be seen, Retransmission Timer is that each HARQ Process among the UE is provided with separately; And in the DRX course of work, a plurality of Process just need a plurality of Retransmission Timer, and this not only can cause the complexity of UE when equipment is realized, and causes also more complicated of the DRX course of work.

Embodiment
Basic thought of the present invention is on the basis of LTE DRX mechanism, has reduced the quantity of timer in the DRX operating process, on the basis that does not influence systematic function, has simplified system's implementation complexity, has obtained power saving effect preferably simultaneously.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The embodiment of the invention 1 provides a kind of method that realizes discontinuous reception, and as shown in Figure 3, this method comprises:
Step 301: default retransmission timer;
Concrete, Retransmission Timer with a plurality of HARQ Process correspondences is reduced to one in the present embodiment, promptly in each UE, preset a Retransmission Timer, and be applied to the HARQ Process that all transmit during DRX;
Step 302: in discontinuous receiving course, adopt the described default a plurality of processes of retransmission timer retransfer scheduling;
Present embodiment is compared with existing scheme, receiving that corresponding RTT Timer starts at after certain process re-transmission control signaling, and DRX Retransmission Timer does not restart; Promptly before RetransmissionTimer is overtime, retransmit at the scheduling of certain process, do not stop RetransmissionTimer if receive eNB; And as the data of other processes after preceding once transmission decoding failure, restart above-mentioned Retransmission Timer; Wherein, the termination of Retransmission Timer is always because this timer expiry;
For example, UE receive that eNB sends retransmit the control signaling at a certain HARQ process after, RTT Timer that should process is started; Still if decoding is unsuccessful after preceding HARQ transmission and to the data in should process, then behind described RTT Timer timer expiry, start RetransmissionTimer, this Retransmission Timer is unique retransmission timer of setting among the UE; And before Retransmission Timer is overtime,, do not stop RetransmissionTimer if receive the re-transmission of eNB scheduling; The reason of termination that it should be noted that the Timer of Retransmission described in the present embodiment is always because this timer expiry; If UE receives the re-transmission control signaling at other process again, its corresponding RTT Timer starts, and when the data in this process still decoding is unsuccessful after preceding HARQ transmission, then behind described RTT Timer timer expiry, current described Retransmission Timer is not overtime, then restart aforementioned Retransmission Timer, and be not to start new Retransmission Timer; Be that a plurality of processes all adopt same Retransmission Timer to carry out retransfer scheduling;
In addition, on above-mentioned basis of simplifying timer, in order further to improve the power saving performance of UE, the give chapter and verse quantity of the retransfer scheduling received during the Retransmission Timer of present embodiment determines whether premature termination Retransmission Timer; If Retransmission Timer is premature termination on the basis that does not influence systematic function, promptly shortened its operating time, thereby can effectively improve the power saving performance of UE; Concrete, be example in the following manner:
(1) when system's initial setting up, the quantity of the retransfer scheduling of receiving during the Retransmission Timer is 0;
(2) when Retransmission Timer started or restarts, the quantity of the retransfer scheduling of receiving during the Retransmission Timer added 1;
When (3) receiving retransfer scheduling during Retransmission Timer, the quantity of the retransfer scheduling of receiving during the Retransmission Timer subtracts 1;
In addition, when the quantity of the retransfer scheduling of receiving during the Retransmission Timer is 0, stop Retransmission Timer;
For example, UE receive that eNB sends retransmit the control signaling at a certain HARQ process after, RTT Timer that should process is started; And if unsuccessful to the data in should process in preceding HARQ transmission back decoding, then behind described RTT Timer timer expiry, start RetransmissionTimer; At this moment, meeting above-mentioned (2) bar rule, is 1 after the quantity of the retransfer scheduling of receiving during the Retransmission Timer adds 1; And when eNB has dispatched the re-transmission of described process once more, meet above-mentioned (3) bar rule this moment, be 0 after the quantity of the retransfer scheduling of receiving during the Retransmission Timer subtracts 1, and Retransmission Timer stop when the quantity of the retransfer scheduling of receiving during the Retransmission Timer is 0;
Simultaneously before above-mentioned Retransmission Timer startup back is overtime, there is other process to be retransmitted scheduling, and the success of not decoding of the data in its process of the overtime back of the RTT Timer of this other process correspondence, then restart Retransmission Timer, meet above-mentioned regular (2) bar this moment, is 1 after the quantity of the retransfer scheduling of receiving during the Retransmission Timer adds 1; And dispatched described other process once more when retransmitting as eNB, meet above-mentioned (3) bar rule this moment, be 0 after the quantity of the retransfer scheduling of receiving during the RetransmissionTimer subtracts 1, and Retransmission Timer stop when the quantity of the retransfer scheduling of receiving during the Retransmission Timer is 0; The retransfer scheduling of a plurality of processes by that analogy, present embodiment repeats no more.
The have particular application as example of method in DRX with the foregoing description is elaborated below, and shown in the embodiment of the invention 2, accompanying drawing 4, this method comprises:
T1 during on duration constantly, receive the initial transmission of process 1 of eNB scheduling after, start Inactivity Timer and RTT Timer1; At t2 constantly since RTT Timer1 is overtime and Process 1 in the data success of not decoding, start the Retransmission Timer of unique setting;
In the t3 moment before Retransmission Timer is overtime, eNB has dispatched the initial transmission of Process 2, and UE restarts Inactivity Timer, and starts RTT Timer2;
T4 before Retransmission Timer is overtime constantly, eNB has dispatched the re-transmission of Process 1, UE restarts RTT Timer1, therefore Process2 also retransmits adopting this Retransmission Timer to wait for the time, so the time do not restart and do not stop Retransmission Timer yet;
At t5 constantly, because RTT Timer2 is overtime, and the success of not decoding of the data among the Process 2, so Retransmission Timer is restarted;
Restart the t6 moment of back before overtime at Retransmission Timer, eNB has dispatched the re-transmission of Process 2, and UE is restarted RTT Timer2; This moment is not overtime because of Retransmission Timer, so it does not stop;
Restart the t7 moment of back before overtime at Retransmission Timer, the success of not decoding of the data among the overtime and Process 1 of RTT Timer1 is so Retransmission Timer is restarted once more;
At Retransmission Timer by the t8 before overtime after restarting once more constantly, eNB has dispatched the re-transmission of Process 1, and UE restarts RTT Timer1, does not also stop Retransmission Timer but do not restart;
Before RTT Timer2 was overtime, UE was to the success of the data decode among the Process 2, and feeding back ACK then; But after RTT Timer2 is overtime, retransmit because of Process1 is adopting this Retransmission Timer to wait for, and Retransmission Timer is not overtime, so it does not restart; At t9 constantly, Retransmission Timer stops owing to overtime; And before RTT Timer1 was overtime, UE was to the success of the data decode among the Process 1, and feeding back ACK, after RTT Timer1 is overtime, also need not to restart Retransmission Timer.
The embodiment of the invention 3: in order further to improve the power saving performance of UE, introduce variable P, be used for writing down the quantity of the retransfer scheduling of receiving during the Retransmission Timer, and determine whether premature termination Retransmission Timer according to the P value:
(1) when system's initial setting up, P=0;
(2) when Retransmission Timer starts or restarts, P=P+1;
When (3) during Retransmission Timer, receiving retransfer scheduling, P=P-1;
In addition, when P=0, stop Retransmission Timer.
Introduce behind the P the course of work as shown in Figure 5:
T1 during on duration constantly, receive the initial transmission of process 1 of eNB scheduling after, start Inactivity Timer and RTT Timer1; This moment, P was initialized as 0;
At t2 constantly since RTT Timer1 is overtime and Process 1 in the data success of not decoding, start the Retransmission Timer of unique setting; Meet above-mentioned (2) bar rule, P=1 this moment;
In the t3 moment before Retransmission Timer is overtime, eNB has dispatched the initial transmission of Process 2, and UE restarts Inactivity Timer, and starts RTT Timer2;
At t4 constantly, eNB has dispatched the re-transmission of Process 1, and UE starts RTT Timer1; Meet above-mentioned (3) bar rule P=0 this moment, and Retransmission Timer is terminated when P=0;
At t5 constantly, because RTT Timer2 is overtime, and the success of not decoding of the data among the Process 2, Retransmission Timer is restarted; Meet above-mentioned (2) bar rule, P=1 this moment;
At t6 constantly, eNB has dispatched the re-transmission of Process 2, and UE starts RTT Timer2; Meet above-mentioned (3) bar rule P=0 this moment, and Retransmission Timer is terminated when P=0;
In the t7 success of not decoding of the data among the overtime and Process 1 of RTT Timer1 constantly, Retransmission Timer is restarted; Meet above-mentioned (2) bar rule P=1 this moment;
At t8 constantly, eNB has dispatched the re-transmission of Process 1, and UE restarts RTT Timer1; Meet above-mentioned (3) bar rule P=0 this moment, and Retransmission Timer is terminated when P=0;
Then before RTT Timer2 is overtime, UE is to the success of the data decode among the Process 2, this moment P=0 then Retransmission Timer still stop; At t9 constantly, promptly RTT Timer1 overtime before, UE is to the success of the data decode among the Process 1, and feeding back ACK, then after RTT Timer1 is overtime ,=still equal 0, then Retransmission Timer also still stops, and need not to restart.
As can be seen, adopt the method for the invention described above embodiment, on the basis of LTE DRX mechanism, the Retransmission Timer of a plurality of HARQ Process correspondences is reduced to one, promptly each UE is provided with a Retransmission Timer; By the quantity of retransmission timer in the minimizing DRX operating process, thereby on the basis that does not influence systematic function, simplified system's implementation complexity; Simultaneously come premature termination RetransmissionTimer, thereby obtained power saving effect preferably according to the quantity of the retransfer scheduling of receiving during the Retransmission Timer.
