Specific embodiment
DRX is described below, concept as " idle (idle) state ", " connection (connected) state " is from wireless
For resources control (Radio Resource Control, RRC) layer angle；In simple terms, when UE is completed in some cell
After resident, then the UE is claimed to enter " Idle state ".If the UE is subsequent and random access procedure is completed, the UE is claimed to enter
" connected state ".Either Idle state or connected state, UE will monitor always downlink PDCCH subframe, check whether to come from
The information of serving cell.The problem of appearing not to is done so, however reality is many times, UE is not to carry out with network always
The interaction of effective information, will not always execute upload or downloading service, and when call will not have always the transmission of voice data.
Most of time, UE and network are not data interactions, if this when of UE also goes lasting monitoring PDCCH subframe,
It is clearly very power-consuming.Thus, under the premise of guaranteeing that data can be transmitted effectively, it is necessary to design a kind of machine for saving UE electricity
System, this mechanism are just called DRX.
This mechanism of DRX can allow UE periodically to enter sleep state (sleep mode) sometimes, not go to supervise
When listening PDCCH subframe, and need to monitor, then (wake up) is waken up from sleep state, can thus UE be made to reach province
The purpose of electricity.Although having a certain impact in this way to the time delay of data transmission, but if this time delay has no effect on user experience,
Power consumption so even more important in view of UE, it is meaningful for executing DRX.
One typical DRX cycle is as shown in Figure 1, this period of mark " duration (On Duration) " is UE
The time of downlink PDCCH subframe is monitored, inner in " duration ", UE is in wake-up states.Identify " DRX sleeping time
In this period of (Opportunity for DRX) ", UE for power saving, enter sleep without monitor PDCCH subframe when
Between.It can be seen that, the time for DRX sleep is longer, and the power consumption of UE is lower, but corresponding business from this Fig. 1
The time delay of transmission also can and then increase.
Such a scene is considered below: 0 work song frame is the last one subframe of wakeup time OnDuration, at this time
Network side just has the data of a larger byte to need to issue UE, these data can not all have been sent in 0 work song frame.If
It will not go to receive from any of net side again then UE will enter DRX sleep state in 1 work song frame according to the DRX cycle of Fig. 1
Downlink PDSCH data.Network side can only also terminate until DRX cycle, and when next OnDuration moment arrives, and continue
The data without having passed are sent to UE.Although this treatment mechanism is without mistake, it is apparent that increasing the processing delay of entire business.
In order to avoid the appearance of such case, drx-Inactivity timer as shown in Figure 2 is increased in DRX mechanism.If DRX
Inactivity timer (DRX-InactivityTimer) is currently running, even if then originally configuration the OnDuration time
Through terminating, UE is there is still a need for monitoring downlink PDCCH subframe is continued, until DRX InactivityTimer time-out.Increase DRX-
After InactivityTimer mechanism, it is clear that the processing delay of data can be reduced.
The effect that Fig. 2 describes DRX-InactivityTimer is processing delay in order to reduce data, but if DRX-
The duration of InactivityTimer is arranged too long, and timer is overtime not yet after the data of network layer have been sent, then UE
It also have to continue to monitor downlink subframe, can not timely enter sleep state.In order to quickly allow UE to enter sleep shape as far as possible
State, system introduce a MAC Control Element DRX command relevant to DRX.Do not have up and down when network side detects
When row data can pass, media can be sent to the UE and intervene control layer (Media Access Control, MAC) protocol data list
First (Protocol Data Unit, PDU) carries a DRX command control unit in this PDU.When UE receives this
After DRX control unit, OnDurationTimer and DRX-InactivityTimer will be stopped, entering DRX as soon as possible.
A DRX cycle is equal to the summation of UE wakeup time (ON-duration) and sleeping time in Fig. 1.In LTE,
Short cycle (short DRX cycle) or long period (long can be respectively configured to UE according to different business scenarios in system
DRX cycle).Such as when carrying out VOIP business, the usual 20ms of audio coder & decoder (codec) sends a VOIP packet, then
Configured length is the DRX short cycle of 20ms, and the longer quiet period during voice communication, so that it may configure DRX long period.Such as
Fruit is configured with short cycle and long period, and DRXShortCycleTimer timer expiry simultaneously, then UE will enter a vice-minister
DRX cycle opens DRXShortCycleTimer after DRX-InactivityTimer is overtime.
Parameter relevant to DRX is described below, as follows:
OnDurationTimer: the parameter indicate in a DRX cycle, UE wake up after online hours.With PDCCH
Number of sub-frames is basic unit, for example psf6 indicates when a length of 6 PDCCH subframes of UE on-line monitoring.When UE meets DRX cycle
When condition, OnDurationTimer will be entered.
DRX-InactivityTimer: the parameter indicates after UE is successfully decoded to a downlink PDCCH, it is also necessary to
Continue to monitor how many a PDCCH subframes.Equally using PDCCH number of sub-frames as basic unit, for example, psf80 indicate UE also need after
80 downlink PDCCH subframes of continuous monitoring just can enter sleep state.When showing new upstream or downstream transmission in PDCCH subframe
Start the timer, stops the timer when receiving Go-To-Sleep CE.
DRX-RetransmissionTimer: this parameter is used in the scene that downlink retransmits.It is used due to downlink HARQ
It is asynchronous retransmission, therefore when UE and uncertain eNB can issue re-transmission data, but UE is also impossible under unconfined waiting
It goes, UE also needs power saving after all, it is also necessary to enter sleep state, so this retransmission timer is to indicate UE to receive expectation
Downlink retransmitted data, the maximum PDCCH number of sub-frames for needing continuously to monitor.Equally using PDCCH number of sub-frames as basic unit,
For example psf8 indicates UE to receive downlink retransmitted data, it is also necessary to continue waiting for most 8 downlinks PDCCH subframes.Work as HARQ
Start the retransmission timer when not being decoded into function there are also data in RTT timer expiry and downlink HARQ caching, when receiving
When PDCCH subframe shows that the process there are data to transmit or currently belong to DL-SPS subframe, stop the timer.HARQ RTT timing
Device is once time-out means that UE can start to receive the re-transmission data of the side eNB, if there are no overtime, eNB for RTT timer
Re-transmission data will not be issued.
DRXStartOffset parameter, this parameter are meant that DRX cycle is such as period since which subframe
It is 10 subframes, then the range of DRXStartOffset is exactly 0~9；And if the period is 20 subframes,
The range of DRXStartOffset is exactly 0~19, the gapOffset in somewhat similar measurement GAP
LongDRX-CycleStartOffset: this parameter can indicate simultaneously longDRX-Cycle and
This two layers of meaning of DRXStartOffset, as unit of subframe.For example long period selects sf1280, offset selection 0.But it needs to infuse
Meaning, if net side also provided short cycle (ShortDrx-Cycle) parameter simultaneously, long period must be arranged to short
The integral multiple in period.For example short cycle configuration is sf64 (64 subframes), then long period cannot configure sf80, because 80
Aliquant 64.
ShortDRX-Cycle: this parameter indicates the short cycle duration that DRX is used, and as unit of subframe, sf5 indicates short
Cycle duration (time containing on-duration) is 5 subframes.
DRXShortCycleTimer: the expression of this parameter continues how many a subframes in short cycle and does not receive PDCCH
Enter long period.If value is 2, then it represents that continue (2 × shortDRX-Cycle) a subframe and PDCCH is not successfully decoded
Enter long period.
That is: parameter relevant to timer is all and relevant to the period to be all as unit of PDCCH subframe
As unit of subframe.
Discontinuous reception mechanism allows UE to periodically enter sleep state, does not go to monitor PDCCH subframe, only is needing to supervise
It is just waken up from sleep when listening, thus achievees the purpose that power saving.Now VoLTE business DRX relevant configured parameter is as follows in net:
| Timer Timer | Parameter value |
| DRX long period (LongDrxCycle) | SF40 |
| Duration timer (OnDurationTimer) | PSF8 |
| DRX inactivity timer (DRX-InactivityTimer) | PSF4 |
| DRX waits the timer (DRXReTxTimer) for retransmitting data | PSF4 |
Wherein SF indicates subframe, and SF40 indicates 40 subframes；PSF indicates PDCCH subframe, and PSF4 indicates 4 PDCCH
Frame.
After VoLTE business opens discontinuous reception (Discontinuous Reception, DRX) mechanism, human hair of the present invention
Show following uplink packet loss problem:
Terminal (User Equipment, UE) reporting buffer status report (Buffer Status Report, BSR) it
Afterwards, subsequent base stations send scheduling UE Physical Downlink Control Channel (Physical Downlink Control Channel,
PDCCH) subframe moment UE enters DRX dormant period, at the same time, the base station of certain producers not when UE enters activated state again
The UE is dispatched, UE ascending packet data convergence protocol (Packet Data Convergence Protocol, PDCP) is caused to be lost
It abandons timer (discard timer) time-out and abandons packet, it is 100 milliseconds (ms) that PDCP, which abandons the timing length of timer setting, at present
To 300ms, PDCP abandons timer will occur actively to abandon packet in timing time-out.
The reason of above-mentioned uplink abandoning packet problem occurs occur mainly two o'clock:
Reason one, agreement are not directed to uplink synchronous HARQ situation design DRX mechanism.As shown in table 1 below, it is exercised on LTE
With synchronous HARQ, re-transmission can be it is adaptive, be also possible to it is non-adaptive.Consider that UE just enters suspend mode after sending BSR
The scene of phase, when base station BS R decoding failure and when non-adaptive ascending resource and random access resource collide or base station
When BSR is successfully decoded, it is confirmation character that base station, which can only use synchronous self-adapting HARQ to retransmit through PHICH feedback,
(Acknowledgement, ACK) and cannot feed back at once PDCCH instruction because UE is now in dormant period and cannot monitor
PDCCH.Agreement it is not perfect, cause uplink synchronous HARQ re-transmission cannot proceed normally.
Reason two, it can be seen that, the base station of some producers does not enter activated state (next in UE from existing net problem
During Duration) after to UE send BSR carry out subsequent processing, i.e., do not issue UL Grant corresponding with BSR.Meanwhile
SS later does not initiate SR again, until retxBSR-Timer time-out (now net default setting is 320ms at present).And
Already it has been more than PDCP discard timer (now net configuration 100ms~300ms) when retxBSR-Timer time-out, therefore has led
Uplink has been caused to abandon packet problem.
Table 1: uplink synchronous HARQ operation (UL synchronous HARQ Operation)
In reason two, UE it is subsequent again initiate scheduling request (Scheduling Request, SR) until
The reason of retxBSR-Timer time-out is: being described according to agreement, there are three types of BSR: 1, routine BSR (Regular BSR)；2,
Periodical BSR (Periodic BSR)；3, BSR (Padding BSR) is filled.In 3 kinds of BSR, only routine BSR will send and not have
When there are enough ascending resources, scheduling request can be just triggered.In general, there are three types of the case where triggering routine BSR: 1) when UE is slow
When rushing area buffer as sky, and thering are data to enter buffer；2) when buffer non-empty, and the data of high priority enter
When buffer；3) when retxBSR-Timer time-out causes to retransmit BSR.
According to the triggering mode description of Regular BSR in existing protocol, the buffer area UE be not it is empty and during this period in UE
It is likely to no high-priority data and enters buffer, therefore UE can only be until retxBSR-Timer overtime (more than 320ms)
Scheduling request can be triggered, and when retxBSR-Timer time-out has already been more than PDCP discard timer (now net configuration
100ms~300ms), therefore result in uplink and abandon packet problem.
The technical solution of the present invention is further elaborated in the following with reference to the drawings and specific embodiments.
The present embodiment proposes a kind of lower ascending transmission method of DRX configuration, and this method is realized applied to terminal, this method
Function can realize that certain program code can be stored in memory by the processor caller code in terminal
In, it is seen then that the terminal includes at least processor and memory.
Fig. 3 is the implementation process schematic diagram of the ascending transmission method under DRX of embodiment of the present invention configuration, as shown in figure 3, should
Method includes:
After step S301, UE send MAC PDU to base station, starting timer starts timing；
Here, the MAC PDU includes at least one of: BSR MAC Control Element (Control Element, CE)；
Upstream data.That is, the MAC PDU perhaps only can include upstream data or both having included only to include BSR MAC CE
BSR MAC CE includes upstream data again.
Here, " rear " in after UE sends MAC PDU to base station can refer to P time of day, such as subframe, a meter
Shi Danwei is usually millisecond or subframe.Certain those skilled in the art can also open according to determination at the time of sending MAC PDU
At the time of dynamic timer, such as at the time of by being determined as starting timer at the time of sending MAC PDU, alternatively, MAC will be sent
At the time of plus P time of day of delay or in advance, P time of day is as dynamic timer at the time of PDU, when P is equal to 0, i.e.,
At the time of by being determined as starting timer at the time of sending MAC PDU.
Step S302, in the timer timing length, the UE monitors PDCCH subframe.
Step S303, if receiving PDCCH new biography/retransmission instruction of base station in the PDCCH subframe monitored, UE is carried out
Trigger data new biography/re-transmission.
In other examples, timer can have different types, such as timer can be fixed duration timing
Device or endless timer, wherein fixed duration timer is that timing length is fixed periodic timer,
Endless timer refers to that timing length is not fixed, i.e. the period of timer does not immobilize, when some condition meets
It waits, timer will terminate；In other words, endless timer is actually a kind of timer of cycle dynamics, below according to
The type of timer is discussed respectively:
In other examples, the timing length of the timer is fixed duration, the method also includes: described
In timer timing length, if receiving PDCCH new biography/retransmission instruction of base station in the PDCCH subframe monitored, the UE after
It is continuous to monitor physical downlink control channel PDCCH subframe；After the timer expired, no longer monitoring PDCCH.
Here, timer is fixed duration timer 1: during timer operation, UE needs persistently to monitor PDCCH
Frame；In the range of timer 1, if UE receives PDCCH new biography/retransmission instruction, continue to monitor PDCCH until timer 1
Timing termination, and the PDCCH new biography/retransmission instruction is responded, UE carries out new biography/re-transmission of trigger data.Fixed duration timing
After 1 time-out of device, if being not received by PDCCH new biography/retransmission instruction, UE monitors PDCCH without continuing.
In other examples, the timer is DRX inactivity timer；In DRX inactivity timer timing
In length, the UE monitors PDCCH subframe, after DRX inactivity timer time-out, monitors PDCCH without continuing.
Here, which can be multiplexed DRX inactivity timer (DRX-InactivityTimer), in the timer
During operation, UE monitors PDCCH subframe, after the timer expiry, monitors PDCCH without continuing；
In other examples, the timing duration of the timer is shorter than the timing duration that PDCP abandons timer；Institute
State method further include:
If the UE does not receive always PDCCH new biography/re-transmission of base station transmission in the timing length of the timer
Instruction then triggers BSR retransmission request, and the BSR retransmission request is for requesting ascending resource in order to retransmit the MAC PDU.
Here, the timing length of timer is shorter than the fixation duration timer 3 of PDCP discard timer: starting timing
Device 3, if UE has sent uplink MAC PDU but do not receive base station transmission always during fixed duration timer 3 is run
PDCCH new biography/retransmission instruction then triggers BSR request, and request ascending resource is for retransmitting the MAC PDU.If monitored
PDCCH new biography/retransmission instruction that base station is received in PDCCH subframe, then respond the PDCCH new biography/retransmission instruction, and UE is carried out
Trigger data (data) new biography/re-transmission；In timing range, UE is not if the PDCCH new biography/retransmission instruction for receiving base station
It needs to continue to monitor PDCCH subframe.
In other examples, the timer is no limit timer, the method also includes: if monitor
PDCCH new biography/retransmission instruction of base station is received in PDCCH subframe, then endless timer timing termination, described in response
PDCCH new biography/retransmission instruction, UE carry out trigger data new biography/re-transmission.
Here, start endless timer, UE needs persistently to monitor PDCCH subframe, if connect in the PDCCH subframe monitored
PDCCH new biography/retransmission instruction of base station is received, then endless timer timing terminates, and responds the PDCCH new biography/weight
Instruction is passed, UE carries out triggering data new biography/re-transmission；UE needs persistently to monitor PDCCH subframe until the PDCCH for receiving base station is new
Biography/retransmission instruction.
The present embodiment proposes a kind of lower ascending transmission method of DRX configuration, and this method is realized applied to terminal, this method
Function can realize that certain program code can be stored in memory by the processor caller code in terminal
In, it is seen then that the terminal includes at least processor and memory.
Fig. 4 is the implementation process schematic diagram of the ascending transmission method under DRX of embodiment of the present invention configuration, as shown in figure 4, should
Method includes:
After step S401, UE send MAC PDU to base station, starting first timer starts timing；The first timer
When it is a length of from the UE send MAC PDU at the time of to PHICH corresponding with the moment feedback moment duration；
Here, the starting first timer starts timing, comprising: UE determine itself to base station send MAC PDU when
Carving was the first moment, starts the first timer at first moment and starts timing；Determination is corresponding with first moment
The PHICH feedback moment be the second moment, the first timer timing described in second moment terminates.The duration of the timer
To the duration PHICH corresponding with the moment feedback moment at the time of to send MAC PDU from UE.It is run in the timer
Period, UE are not listening to PDCCH.
Step S402, after the first timer time-out, the UE continues to monitor adjacent N number of PDCCH after time-out
Subframe；The N is the integer more than or equal to 1；
Step S403, if receiving PDCCH new biography/retransmission instruction in adjacent N number of PDCCH subframe, without continuing
PDCCH and the response PDCCH new biography/retransmission instruction are monitored, trigger data new biography/re-transmission is carried out.
In other examples, the method also includes:
Terminal UE sends MAC PDU to base station, starts second timer, and the timing length of the second timer is shorter than
PDCP abandons timer；Outside the timing length of the first timer and in the timing length of the second timer, such as
UE described in fruit does not receive always PDCCH new biography/retransmission instruction of base station transmission, then triggers Buffer Status Report BSR re-transmission and ask
It asks, the BSR retransmission request is for requesting ascending resource in order to retransmit the MAC PDU.
Here, the second timer is fixed duration timer 3, i.e. the timing length of timer is shorter than PDCP
discard timer。
In other examples, the method also includes: after first timer time-out, if the UE passes through
PHICH receives the negative confirmation character (Negative Acknowledgement, NACK) of base station feedback, then the UE is not necessarily to
Continue to monitor PDCCH.
In other examples, the method also includes:
Step S11, after the first timer time-out, if the UE only passes through PHICH and receives base station feedback
ACK and not when adjacent N number of PDCCH subframe receives PDCCH new biography/retransmission instruction, the UE starts fixed duration
Timer.
Here, the fixed duration timer is multiplexed DRX uplink retransmission timer.Fixed duration timer can be above-mentioned
Timer 1.
Step S12, in the fixed duration timer timing length, the UE monitors Physical Downlink Control Channel
PDCCH subframe；
Step S13, if in the fixed duration timer timing length, if received in the PDCCH subframe monitored
PDCCH new biography/retransmission instruction of base station, then respond the PDCCH new biography/retransmission instruction, and UE carries out trigger data new biography/weight
It passes.
Here, in the fixed duration timer timing length, if receiving base station in the PDCCH subframe monitored
PDCCH new biography/retransmission instruction, the UE continue to monitor physical downlink control channel PDCCH subframe；In the timer expired
Afterwards, PDCCH is no longer monitored.
In other examples, the N is the integer more than or equal to 2, the method also includes:
If the UE after a time out after adjacent i-th of PDCCH subframe receive PDCCH new biography/retransmission instruction,
UE no longer monitor described i-th after a PDCCH subframe of residue (N-i), and the UE responds the PDCCH new biography/re-transmission
Instruction, the UE carry out trigger data new biography/re-transmission, wherein i is the integer more than or equal to 1 and less than or equal to (N-1)；
If the UE after a time out after adjacent i-th of PDCCH subframe be not received by PDCCH new biography/re-transmission and refer to
Show, then UE continues to monitor (i+1) a PDCCH subframe.
The embodiment of the present invention provides the ascending transmission method under a kind of DRX configuration, this method comprises:
The case where for being configured with DRX, UE is after some uplink synchronous HARQ process has sent uplink MAC PDU, starting
Preset timer.Preset timer can be following one of four or combined use:
A) fixed duration timer 1: during timer operation, UE needs persistently to monitor PDCCH subframe；In timer
In the range of 1, if UE receives PDCCH new biography/retransmission instruction, continue to monitor PDCCH until 1 timing termination of timer, and
PDCCH new biography/the retransmission instruction is responded, UE carries out new biography/re-transmission of trigger data.After fixed 1 time-out of duration timer, such as
Fruit is not received by PDCCH new biography/retransmission instruction, and UE monitors PDCCH without continuing.Fixed duration timer 1 can be multiplexed existing
There is DRX-InactivityTimer.
B): during timer 2 operation, UE is without monitoring PDCCH instruction.The length of timer 2 is to send the uplink
To the duration between PHICH corresponding with the moment feedback at the time of MAC PDU.Divide three kinds of situations to discuss below: 1) this is fixed
When device time-out after, UE needs to monitor N number of such as 1 PDCCH subframe, i.e., identical subframe is fed back with PHICH, if UE is in the son
Frame receives PDCCH new biography/retransmission instruction, without continue to monitor PDCCH and and respond the PDCCH new biography/retransmission instruction,
UE carries out triggering data new biography/re-transmission；2) after the timer expiry, if UE receives the NACK of base station feedback by PHICH,
Then without continuing to monitor PDCCH.3) if it is new only not receive PDCCH by the ACK that PHICH receives base station feedback by UE
When biography/retransmission instruction, start fixed duration timer 4, during fixed duration timer 4 is run, UE needs lasting monitor
PDCCH subframe, existing DRX-ULRetransmissionTimer can be multiplexed by returning to the fixed duration timer 4 of situation a).
Here, during timer 2 operation, UE is without monitoring PHICH.After timer expiry, UE needs to monitor 1
PDCCH subframe.In the PDCCH subframe, UE needs to read the PHICH information (i.e. NACK or ACK) of base station feedback simultaneously.This reality
It applies in example, when asynchronous HARQ can monitor multiple PDCCH subframes；When synchronous HACQ, multiple PDCCH subframes can be monitored, certainly
1 can also be only monitored, in other examples, circulation is monitored, and first adjacent PDCCH subframe has been supervised after time-out
Hear PDCCH new biography/retransmission instruction, then there is no need to monitor second PDCCH subframe, if first adjacent after time-out
PDCCH subframe does not listen to PDCCH new biography/retransmission instruction, then needs to monitor second PDCCH subframe, until N number of.
C) endless timer: starting endless timer, UE need persistently to monitor PDCCH subframe, if monitor
PDCCH new biography/retransmission instruction of base station is received in PDCCH subframe, then endless timer timing terminates, and described in response
PDCCH new biography/retransmission instruction, UE carry out triggering data new biography/re-transmission；UE needs persistently to monitor PDCCH subframe until receiving
PDCCH new biography/retransmission instruction of base station；
D) duration is shorter than the fixation duration timer 3 of PDCP discard timer: starting timer 3, in timing range
Interior, UE needs persistently to monitor PDCCH subframe；If UE has sent uplink MAC PDU but during fixed duration timer 3 is run
PDCCH new biography/the retransmission instruction for not receiving base station transmission always inside then triggers BSR request, and request ascending resource is for retransmitting institute
State MAC PDU.If receiving PDCCH new biography/retransmission instruction of base station in the PDCCH subframe monitored, the PDCCH is responded
New biography/retransmission instruction, UE carry out triggering data new biography/re-transmission；
Here, the MAC PDU perhaps only can include upstream data or both having included only to include BSR MAC CE
BSR MAC CE includes upstream data again.
Embodiment one: situation is used in combination in timer 2 and timer 3
UE starts timer 2 and retransmission timer 3 after sending BSR.It is shown in Figure 5, it is transported in timer 2
Between the departure date, UE is without monitoring PDCCH.UE monitors 1 PDCCH subframe after timer 2 time-out, but UE is not in the subframe
Have and receive new biography/retransmission instruction that base station issues, therefore UE opens timer 4, monitors PDCCH instruction for continuing.Directly
It is all not received by 4 time-out UE of timer and retransmits new biography instruction, therefore UE enters dormant period.At the same time, it is transported in timer 3
Between the departure date, UE is not received by PDCCH new biography/retransmission instruction always, therefore after 3 time-out of timer, UE trigger SR request with
Request repeat resource.
Increase the method for event triggering BSR a kind of in technical solution provided in this embodiment: if UE has sent uplink MAC
PDU, but before duration is shorter than the fixation duration timer expiry of PDCP discard timer, do not receive base station transmission always
PDCCH new biography/retransmission instruction, then trigger BSR retransmission request.For uplink synchronous HARQ situation in the case of DRX, UE needs are being sent out
It send and monitors PDCCH in PHICH subframe corresponding to the MAC PDU moment, to receive base station re-transmission/new biography instruction.
Compared with prior art, the present embodiment can effectively solve DRX open in the case of, UE send upstream data after but into
Enter dormant period and then uplink packet loss problem caused by the scheduling of base station cannot be received in time.
In the case where existing net VoLTE business opens DRX, after UE reporting buffer status report (BSR), some base stations are simultaneously
Uplink authorization (UL grant) corresponding with BSR is not issued, and UE is retransmitting timer (retxBSR-Timer) time-out of BSR
It is preceding also not initiate scheduling request (SR).Since the duration of retxBSR-Timer is longer than PDCP packet loss timer (PDCP discard
Timer duration), therefore the problem of will lead to UE packet loss.In this regard, the present embodiment proposes following roadmap: UE is sent out to base station
After sending MAC PDU, start a timer；
The timer can be multiplexed DRX inactivity timer (DRX-InactivityTimer), in the timer runtime
Between, UE monitors PDCCH subframe, after the timer expiry, monitors PDCCH without continuing；Alternatively,
The timer when it is a length of from UE send MAC PDU at the time of to PHICH corresponding with the moment feedback moment it
Between duration.During timer operation, UE is not listening to PDCCH.After the timer expiry, UE needs to monitor 1 PDCCH
Subframe feeds back identical subframe with PHICH.If UE receives PDCCH new biography/retransmission instruction in the subframe or UE passes through
PHICH receives the NACK of base station feedback, then without continuing to monitor PDCCH.If UE, which only passes through PHICH, receives base station feedback
ACK and when not receiving PDCCH new biography/retransmission instruction, starting duration is equal to DRX uplink retransmission timer (DRX-
ULRetransmissionTimer) the timer of duration, during timer operation, UE needs persistently to monitor PDCCH
Frame；Alternatively,
The timer is no limit timer, and during timer operation, UE needs persistently to monitor PDCCH until connecing
Receive PDCCH new biography/retransmission instruction of base station；Alternatively,
The timer duration is shorter than PDCP discard timer, after the timer expiry, if non-As-received always
PDCCH new biography/the retransmission instruction stood then triggers BSR request.
After the present embodiment requires UE to send MAC PDU to base station, starting duration is shorter than determining for PDCP discard timer
When device, after the timer expiry, if not receiving PDCCH new biography/retransmission instruction of base station always, trigger BSR request, keep away
Exempt from because continue not receive base station UL grant caused by packet loss problem.
In the present embodiment, after (1) UE sends MAC PDU to base station, starting duration is shorter than PDCP discard timer's
Timer, if not receiving PDCCH new biography/retransmission instruction of base station always, triggers BSR request after the timer expiry；
(2) UE monitors PDCCH on sending PHICH subframe corresponding to the MAC PDU moment.
