Description

Starting method, user equipment, base station and the system of DRX mode

Technical field

The present invention relates to the communications fields, in particular to a kind of discontinuous reception (Discontinuous Reception, referred to as DRX) mode starting method, user equipment, base station and system.

Background technique

In long term evolution (Long Term Evolution, referred to as LTE) system, for user equipment (User Equipment, referred to as UE) power saving, define DRX mode.In the drx mode, UE need not each subframe carry out under physics Row control channel (Physical Downlink Control Channel, referred to as PDCCH) blind Detecting receives electricity to close Road provides condition.

In the drx mode, active period (Active Time) and inactive phase (Non-active Time) alternately exist, UE It leaves Active Time and enters Non-active Time.In the drx mode, it is only necessary to during Active Time by UE Carry out PDCCH blind Detecting.Active Time is configured according to evolved base station (Evolved Node B, referred to as eNodeB) DRX parameter and determine the case where traffic scheduling.Fig. 1 is the signal according to the DRX scene without business of the relevant technologies Figure, in Fig. 1, A point is " Start/Restart onDuration Timer(starts/restart onDuration Timer) " Point, B point are " onDuration Timer expires(onDuration Timer time-out) " point.As shown in Figure 1, Active Time is started by the period, during Non-active Time is entered when not having business transmission, and is needed until next cycle During Active Time can be reentered.

In the related art, DRX configuration parameter be base station wireless heterogeneous networks (Radio Resource Control, Referred to as RRC) it is sent to UE's in connection reconfiguration message.DRX configuration parameter includes: (onDuration Timer), drx- Inactivity Timer and drx-Retransmission Timer etc..It is one or more fixed when having in these timers When device at runtime, it is believed that during UE is in the Active Time of DRX mode.

Fig. 2 is according to the schematic diagram of the DRX scene for having business of the relevant technologies, and in Fig. 2, A and B are identical as Fig. 1, C/E Indicate that " Found a PDCCH, then Start/Restart InactivityTimer(has found PDCCH, starts or restarts InactivityTimer) ", D is SR send(SR transmission), F is InactivityTimer expires (InactivityTimer time-out).

As shown in Fig. 2, onDuration Timer is the timer periodically started, drx-Inactivity Timer is The timer started when new business scheduling is received, drx-Retransmission Timer is to receive down mixing and weighing automatically The timer for passing request (Hybrid Automatic Repeat Request, referred to as HARQ) retransfer scheduling and being arranged.Separately Outside, when UE sends scheduling request (Scheduling Request, referred to as SR) to base station requests uplink authorization (UL Grant) Afterwards, and before SR Pending does not cancel, it is believed that during UE is in Active Time.When being possible to receive uplink retransmission When authorization and uplink automatic repeat request buffer area (HARQ Buffer) non-empty, also think that UE is in the Active Time phase Between.During also having specific Active Time in the random access procedure.

In the related art, based on DRX described above definition and DRX configuration distributing mode, it is understood that there may be base station and UE The opportunity for starting DRX mode is different, when base station does not enter into DRX mode and UE enters DRX mode, it is understood that there may be UE does not go to examine The PDCCH scheduling that base station issues is surveyed, traffic scheduling loss and subsequent exception are caused.

For example, base station can specify UE and have received what base station issued when message is completed in the RRC reconfiguration for receiving UE RRC reallocation message then starts to start DRX mode.And UE (carries DRX to match receiving the RRC reallocation message that base station issues Set) when start DRX mode immediately.

Fig. 3 be according to the RRC reconstitution process and DRX mode of the relevant technologies start scene schematic diagram, in Fig. 3, A, B and Fig. 1 is identical, and C, E and D are identical as Fig. 2, and F/G is super for Inactivity Timer expires(Inactivity Timer When), H/J is reconfigured for RRC reconfiguration complete send(RRC and is completed message sending), I/K RRC Reconfiguration complete HARQ retransmission(RRC reconfigures the HARQ re-transmission for completing message), L is RRC reconfiguration received and start DRX mode(RRC reconfiguration message receives and starts DRX mould Formula).

Under this application scenarios above and strategy, as shown in figure 3, UE receives RRC reallocation message at the L moment, open immediately DRX mode is moved, during by chance entering onDuration Timer, this onDuration Timer only has 10 milliseconds, connects , UE takes uplink authorization DCI0(Downlink Control Informaion format0, referred to as DCI0 in C point), and H point to base station status report and RRC reconfiguration complete message, H point send HARQ failure, then I point HARQ retransmit at Function, HARQ maximum number of times of transmission is that 2 and Inactivity Timer only has 10 milliseconds, then UE advances to DRX mould after I point During the Non-active Time of formula.However, UE also needs to receive the state report of base station to confirm that base station has received at this time Message is completed in RRC reconfiguration.

Scene as above after base station receives RRC reconfiguration completion message, sends corresponding state report, UE to UE in base station side But it is received during coming into DRX Non-active without going.Alternatively, base station receive RRC reconfiguration complete message when immediately Start DRX mode, configures 256 milliseconds of the period according to DRX, base station, which will wait more than 230 milliseconds, can enter onDuration During Timer and status report is to UE.Then, (timer is 60 millis to the status report messages time-out of UE waiting base station Second), message retransmission process (rlc layer repeating transmission) is completed in triggering RRC reconfiguration, and UE is authorized in the transmission SR request of D point and awarded in E point Power then sends RRC reconfiguration in J point and completes message, possible J point HARQ sends successfully or HARQ fail after it is heavy in K point HARQ Successfully (HARQ maximum number of times of transmission is 2) is sent out, in any case, enters the Non-active Time of DRX mode again in K point UE Period.If issuing state report after message is completed in the RRC reconfiguration that base station receives the transmission of J point, UE be possible between J to K when Between in do not receive success or state report has been fallen in after K point;Or base station does not exist according to DRX cycle and parameter determination During Active Time, not status report.

The state report for completing message is reconfigured for RRC since UE is not received still, UE wait state report time-out, then Secondary triggering RRC reconfiguration completes message sending process, (omitting in schematic diagram 3) repeated as above.The number that transfinites is retransmitted when reaching RLC When, UE will initiate RRC reconstruction process.

See from example above, since UE and base station are starting the out of season of DRX mode for the first time, cause UE cannot and When receive that base station issues complete the state report of message for RRC reconfiguration, completed to cause UE and repeat to send RRC reconfiguration Message and lead to unnecessary power consumption, or even cause RLC re-transmission transfinite and RRC rebuild.
