Description

Timer maintaining method and equipment in carrier aggregation system

Technical field

The present invention relates to wireless communication field, relate in particular to timer maintaining method and equipment in a kind of carrier aggregation system.

Background technology

In the mobile communication system based on shared channel, such as in Long Term Evolution (LTE) system, the transmission of up-downgoing data is responsible for control by base station dispatcher, when scheduler is determined certain terminal of scheduling (UE), what will send or receive data on resource by physical layer control channel (Physical control channel, PDCCH) notification terminal.Terminal monitoring PDCCH when comprising the schedule information of oneself in PDCCH being detected, will complete according to the indication of base station transmission or the reception of data.Under state of activation, owing to terminal uncertain base station when it being dispatched, therefore a kind of common mode of operation is that terminal is monitored PDCCH continuously, is scheduled judging whether.This working method in the situation that the terminal data amount large, may frequently be dispatched and can be obtained higher efficient.Yet for some business, it is irregular that packet reaches the time, may not have for a long time data to arrive, in this case, if terminal monitoring control channel continuously still can increase its power consumption undoubtedly.In order to solve the power consumption problem, the LTE system has adopted discontinuous reception (Discontinuous reception, DRX) mode of operation, under this mode of operation, and the discontinuous monitoring of terminal PDCCH, thus can reach the purpose of economize on electricity.

The basic principle of DRX mechanism as shown in Figure 1.Wherein monitor the period time period of (On duration) expression UE monitoring control channel, open the radio-frequency channel of UE therebetween, and continuous monitoring control channel; Remove outside On duration At All Other Times, UE is in sleep (Sleep) state, and its radio frequency link will be closed, and monitoring control channel no longer is to reach the purpose of power saving.On Duration periodically occurs, and the concrete cycle is by base station (eNB) Configuration.

The DRX mechanism of LTE has been considered the arrival mode of data service, i.e. the arrival of packet happens suddenly, and can be understood as, in case there is packet to arrive, can arrive continuously more grouping within a short period of time so.Arrive characteristics in order to adapt to this business, LTE DRX process has adopted multiple timer, and combines with mixed automatic retransfer request (HARQ) process, to reaching better electricity saving performance.

The relevant timer of DRX comprises lasting timer (OnDurationTimer), discontinuous reception short cycle timer (DrxShortCycleTimer), the inactive timer of discontinuous reception (Drx-InactivatityTimer), mixed automatic retransfer request (HARQ) timer two-way time (RTTTimer) and the discontinuous reception retransmission timer (Drx-RetransmissionTimer) monitored, and is specific as follows:

Periodically the wake up timer of monitoring control channel of OnDurationTimer:UE, as shown in Figure 1.The length of this timer is controlled (RRC) signal deployment by Radio Resource, and take PDCCH subframe (psf) number as unit, minimum value is psf1, and maximum occurrences is psf200.

DrxShortCycleTimer: for the characteristics that better coordinate data service to arrive, the LTE system allows configuration two kinds of DRX cycles (cycle): long period (long cycle) and short period (short cycle).The onDurationTimer of two kinds of cycle is identical, but the time of sleep is different.In short cycle, the sleep time is relatively shorter, UE can be quickly monitoring control channel again.Long cycle must configure, and is the initial condition of DRX process; Short cycle is optional.DrxShortCycleTimer is provided with the time of adopting short cycle to continue, and after DrxShortCycleTimer is overtime, UE will use Long cycle.DrxShortCycleTimer is by the RRC signal deployment, and long measure is the number of short cycle, and span is 1 to 16.

Drx-InactivatityTimer: after having configured DRX, open this timer when allowing to receive in the time (Active Time) of monitoring control channel the control signal of HARQ initial transmission as UE, before this timer expiry, the continuous monitoring control channel of UE.If before Drx-InactivatityTimer is overtime, UE receives the dispatch of HARQ initial transmission, will restart Drx-InactivatityTimer.This timer length is by the RRC signal deployment, and take PDCCH subframe (psf) number as unit, minimum value is psf1, and maximum occurrences is psf2560;

HARQ RTT Timer: be only applicable to down link (DL), make UE might be before retransmit arriving next time monitoring control channel not, reach better power savings.If UE has received the control signal of HARQ transmission (initial transmission or re-transmission), will open this timer.If the decoding after front HARQ transmission of the data in the corresponding HARQ instance process is unsuccessful, UE feeds back negative response (NACK), and after HARQRTT Timer was overtime, UE started Drx-RetransmissionTimer.If the data in the corresponding HARQ instance process are successfully decoded after front HARQ transmission, UE feeds back affirmative acknowledgement (ACK), and after HARQRTT Timer timer expiry, UE does not start Drx-RetransmissionTimer.If current only have HARQ RTT Timer to move, UE is monitoring control channel not.

Drx-RetransmissionTimer: be only applicable to DL.At Drx-RetransmissionTimer therebetween, UE monitors control signal, waits for the retransfer scheduling of corresponding HARQ instance process.This timer length is by the RRC signal deployment, and take PDCCH subframe (psf) number as unit, minimum value is psf1, and maximum occurrences is psf33;

From foregoing description, onDurationTimer, the drx-InactivityTimer in the relevant timer of DRX and the timing length of drx-RetransmissionTimer are based on PDCCH number of sub-frames statistics.For time division duplex (TDD) system, the PDCCH subframe refers to descending sub frame, comprises the descending pilot frequency time slot (DwPTS) in special subframe.The method of adding up the timing length of timer based on the PDCCH number of sub-frames is: at first determine up-downgoing (UL/DL) configuration that current area adopts, subframe when in then this UL/DL being configured, timer starts is as initial subframe, termination subframe when determining timer expiry according to the PDCCH number of sub-frames in this UL/DL configuration, making from initial subframe the number that (comprises initial subframe and stop subframe) the PDCCH subframe that comprises within the time period that stops subframe is described PDCCH number of sub-frames; After initial subframe and termination subframe were determined, the timing length of timer had also just been determined.

Fig. 2 has provided the course of work and the correlation of the relevant timer of above-mentioned DRX.At on duration t1 therebetween constantly, eNB has dispatched the initial transmission for process (process) 1, so UE opens Drx-InactivatityTimer and corresponding HARQ RTT Timer1.Because the initial transmission decoding of Process 1 is unsuccessful, after HARQ RTT Timer was overtime, UE had opened Drx-RetransmissionTimer1.

In the t2 moment, eNB has dispatched the initial transmission for Process 2, and Drx-InactivatityTimer is restarted, and opens simultaneously the HARQ RTT Timer2 for Process 2.

In the t3 moment before Drx-RetransmissionTimer1 is overtime, UE has received the re-transmission for Process 1, then stop Drx-RetransmissionTimer1, and open HARQ RTT Timer1.

After HARQ RTT Timer2 is overtime, because the initial transmission of Process 2 does not have successfully decoded, so UE opens Drx-RetransmissionTimer2.In the t4 moment before Drx-RetransmissionTimer2 is overtime, eNB has dispatched the re-transmission of Process 2, so UE stops Drx-RetransmissionTimer2, opens HARQ RTT Timer2.

In the t5 moment before Drx-RetransmissionTimer1 is overtime, eNB has continued to dispatch the re-transmission of Process1, so Drx-RetransmissionTimer1 is terminated, starts simultaneously HARQ RTT Timer1.Before HARQ RTT Timer2 was overtime, UE was to the success of the data decode in Process 2, so to the eNB feeding back ACK, after HARQ RTT Timer2 is overtime, also do not restart Drx-RetransmissionTimer2 simultaneously.Equally, before HARQ RTT Timer1 was overtime, UE was to the success of the data decode in Process1, so to the eNB feeding back ACK, after HARQ RTT Timer1 is overtime, also do not restart Drx-RetransmissionTimer1.

Can find out in OnDurationTimer, Drx-RetransmissionTimer and Drx-InactivatityTimer, have any one timer to move by said process, UE is with monitoring control channel.

The time of UE monitoring control channel is called again activationary time (Active Time).Active Time also has other factors to affect except the impact that is subjected to DRX timer in the LTE system, and in LTE version 8 (Rel-8), the Active Time of UE comprises the following time:

The first, onDurationTimer or drx-InactivityTimer or drx-RetransmissionTimer or media access control competition solve the time of timer (mac-ContentionResolutionTimer) operation;

The second, UE sends the rear time of waiting for base station scheduling of uplink scheduling request (Scheduling Request, SR);

The 3rd, UE monitors the time for uplink synchronous adaptive retransmission dispatch;

The 4th, UE sends the rear time of waiting for accidental access response of random access lead code (preamble).

The peak rate of long-term evolution upgrading (LTE Advanced, LTE-A) system improves a lot than LTE, requires to reach descending 1Gbps, up 500Mbps.Simultaneously, there are good compatibility in LTE-A system requirements and LTE system.Based on improve peak rate, with LTE system compatible and the needs that take full advantage of frequency spectrum resource, the LTE-A system has introduced carrier aggregation (CA) technology.

Carrier aggregation technology is that terminal can be worked on a plurality of residential quarters simultaneously, and a residential quarter comprises a pair of UL/DL member carrier (Component Carrier, CC), rather than only has the pattern of a cover carrier wave in LTE system and wireless communication system before.Each member carrier can be continuously in the system of carrier aggregation, can be also discrete, and the bandwidth between each member carrier can be identical or different, and in order to keep the system compatible with LTE, the maximum bandwidth limit of each member carrier is 20MHz.It is generally acknowledged that at present the residential quarter number maximum number that terminal can polymerization is 5.In addition, LTE-A also classifies to the residential quarter of carrier aggregation, is divided into main plot (Primary Cell, PCell) and auxiliary residential quarter (Secondary Cell, SCell), wherein: only have a residential quarter to be defined as PCell in the residential quarter of UE polymerization; Other residential quarter except PCell of UE polymerization all is called SCell.

PCell by base station selected and by the RRC signal deployment to terminal, the PCell of different terminals can be different.No matter PCell or SCell, each residential quarter has independently HARQ entity, safeguards a series of independently processes.

LTE-A version 10 (R10) adopts public (common) DRX mechanism, and namely the Active Time of all residential quarters (cell) is identical, safeguards angle understanding namely from the relevant timer of DRX:

OnDurationTimer and drx-InactivityTimer safeguard on any one cell of i.e. terminal polymerization, initial transmission is arranged based on UE, start so the drx-InactivityTimer of UE; Drx-RetransmissionTimer and HARQ RTT Timer processed-based are safeguarded.

In R8/9/10, physical layer standard for TDD system definition following seven kinds of UL/DL configuration, as shown in table 1 below, wherein D represents the DL subframe, U represents the UL subframe, S represents the special subframe of TDD system.

Table 1

In the R11 system, adjacent frequency band can be shared or use to the CA terminal of LTE-A with other system (such as the LTE system), such as shown in Figure 3, the polymerization of LTE-A terminal three residential quarter: Celll, Cell2 and Cell3.Wherein Cell1 uses identical frequency band (Band) 1 with Cell2, and Cell3 uses Band2.Intersect for fear of the up-downgoing of TDD system and disturb, Band1 should use the TDD UL/DL configuration that can coexist with 3G/LTE TDD BandA, and the TDD configuration that what is called can coexist refers to the configuration that does not have the UL/DL intersection to disturb, for the LTE system, what refer to is exactly identical TDD UL/DL configuration.Band2 should use the TDD UL/DL configuration that can coexist with 3G/LTE TDD Band B.If Band A is different with the TDD UL/DL configuration that Band B uses, the TDD UL/DL configuration of Band1 and Band2 use is just not identical yet so.

In realizing process of the present invention, the inventor finds to exist in prior art following technical problem:

In R11, if different TDD UL/DL configurations is supported in the residential quarter of terminal polymerization, UL/DL according to different districts configures so, the timing length of the relevant timer (comprising onDurationTimer, drx-InactivityTimer and drx-RetransmissionTimer) of the DRX take the PDCCH number of sub-frames as the length statistical unit of statistics may be inconsistent on absolute time, and then the overtime moment of the relevant timer of DRX is not identical yet.Be exemplified below, if onDurationTimer length is got psf4, cell1 is different with the TDD UL/DL configuration on cell2, adopt respectively TDD UL/DL configuration 0 and configuration 1, the timing length of the onDurationTimer that configuration is determined respectively according to the UL/DL on cell1 and cell2 so is inconsistent on absolute time, the timing length of adding up the onDurationTimer that obtains according to the configuration of the UL/DL on cell1 is 8ms, be 6ms and configure according to the UL/DL on cell2 the timing length of adding up the onDurationTimer that obtains, as shown in Figure 4.

As seen, when supporting different TDD UL/DL configurations in the residential quarter of terminal polymerization, unique time-out time of determining the relevant timer of the DRX take the PDCCH number of sub-frames as the length statistical unit how, and then safeguard the DRX timer of be correlated with according to this time-out time, be to need at present the problem of solution.

Example 6: choose and trigger the TDD up/down row configuration that use residential quarter that timer starts.This mode is applicable to the relevant timer of DRX of based on data transmission, such as inactive timer (InactivatityTimer), retransmission timer (RetransmissionTimer) etc.Here, for InactivatityTimer, the base station is after the initial transmission dispatch of terminal transmission for a certain residential quarter, with the residential quarter of this residential quarter as triggering InactivatityTimer startup; For RetransmissionTimer, when the base station does not still receive the ACK message that terminal sends after the HARQ RTT Timer that starts for a certain residential quarter is overtime, with this residential quarter as the residential quarter of triggering RetransmissionTimer and starting.

Above-mentioned up/down row configuration selection rule of not making an appointment with terminal can be for random selection rule etc.

better, in order to keep the consistency of terminal and base station, even terminal is determined the timing length of the relevant timer of same DRX according to identical TDD up/down row configuration with the base station, do not configure selection rule with the up/down row that terminal is made an appointment in the base station basis, choose a kind of TDD up/down row configuration from the TDD up/down row configuration that use these a plurality of residential quarters after, the identification information of the part or all of residential quarter of the TDD up/down row configuration that the number information that the base station can configure the TDD up/down row of choosing or use are chosen configures to terminal, the TDD up/down row configuration of using when terminal is chosen at according to the information that receives the timing length of determining the relevant timer of corresponding DRX.

Concrete, RRC signaling or MAC signaling can pass through in the base station, and the identification information with the part or all of residential quarter of the number information of the TDD up/down row configuration chosen or the TDD up/down row configuration that use is chosen configures to terminal.

In this method, the relevant timer of described DRX comprises: one or combination in any in OnDurationTimer, InactivatityTimer, RetransmissionTimer.The base station is that the TDD up/down row configuration that the different relevant timers of DRX is chosen can be identical or different.

In step 61, the base station determine the relevant timer of described DRX timing length method can for: the subframe when in the TDD up/down row configuration of choosing, timer starts is as initial subframe, according to the timer length information for the relevant timer configuration of DRX, termination subframe when determining the relevant timer expiry of DRX in this TDD up/down row configuration makes from initial subframe the number that (comprises initial subframe and stop subframe) the PDCCH subframe that comprises within the time period that stops subframe equal described timer length; The moment that stops the subframe arrival is the overtime moment of the relevant timer of DRX.Initial subframe and stop subframe and determine after, the absolute timing length of the relevant timer of DRX also just determined, i.e. the absolute timing length of the relevant timer of DRX=(terminator frame number-initial subframe numbering) * 1ms.

In step 62, the relevant timer of described DRX is safeguarded according to the overtime moment of determining in the base station, can be in the time period before the relevant timer of DRX starts rear, overtime moment arrival, if the event that does not trigger the relevant timer restart of this DRX or close occurs, safeguard all the time that the relevant timer of this DRX is in running status.

The present invention will be described with specific embodiment for the below:

The present invention has provided a kind of all or part of residential quarter of terminal polymerization and has used under different TDD UL/DL configuring conditions, the method in the overtime moment of the relevant timer of each DRX take PDCCH subframe (DwPTS that comprises special subframe) number as the length statistical unit of how to confirm.

The core concept of this method is namely: can only configure to add up the overtime moment of the relevant timer of certain DRX take PDCCH number of sub-frames (DwPTS that comprises special subframe) as the length statistical unit according to a kind of TDD UL/DL.The relevant timer of each DRX can be respectively with reference to different TDD UL/DL configurations.

Described DRX timer comprises onDurationTimer, drx-InactivatityTimer and drx-RetransmissionTimer.

The principle of TDD UL/DL configuration of determining overtime moment institute's reference of the relevant timer of each DRX has following several:

The first, base station and terminal are used the TDD UL/DL reference configuration of acquiescence.

Need base station and terminal to make an appointment under this principle and use same mode to determine acquiescence TDD UL/DL reference configuration, specifically can determine in the following manner the TDD UL/DL configuration of acquiescence:

Configure with reference to the TDD UL/DL on main plot (PCell).

The TDD up/down row configuration that use residential quarter corresponding to the cell number that reference base station and terminal are made an appointment.

Reference base station is the TDD UL/DL configuration on the minimum residential quarter of radio frames PDCCH number of sub-frames in all residential quarters of terminal configuration or configuration and activation.

Reference base station is the TDD UL/DL configuration on the residential quarter that in all residential quarters of terminal configuration or configuration and activation, in radio frames, the DCCCH number of sub-frames is maximum.

Reference base station is the TDD UL/DL configuration on the timer Abstime that obtains according to PDCCH number of sub-frames statistics in all residential quarters of terminal configuration or configuration and activation the longest residential quarter.

Reference base station is the TDD UL/DL configuration on the timer Abstime that obtains according to PDCCH number of sub-frames statistics in all residential quarters of terminal configuration or configuration and activation the shortest residential quarter.

Base station and terminal acquiescence are used certain TDD UL/DL configuration (not relating to the residential quarter).

For the DRX timer of based on data transmission start, such as drx-InactivityTimer, drx-RetransmissionTimer can configure with reference to the TDD up/down row that use the residential quarter of triggering the timer startup.

The second, terminal is the timer selection reference cell or numbers with reference to TDD UL/DL configuration, such as random selection, then by RRC signaling or MAC CE informing base station.

Should be noted that if terminal is selected same residential quarter or same TDD UL/DL configuration all the time for the relevant timer of each DRX, need not to distinguish timer when configuring reference cell in signaling so.

The 3rd, the base station is terminal configuration timer length reference cell by RRC signaling or MAC CE or directly configures TDD UL/DL configuration numbering.

The base station should be noted that if for all timers configure identical timer length reference cell or TDD UL/DL configuration numbering all the time, need not to distinguish timer when need not so to distinguish the configuration reference cell in signaling.

In addition, above-mentioned the most typical definite mode of just having listed the DRX timer length statistical-reference TDD UL/DL configuration of determining take the PDCCH number of sub-frames as the length statistical unit is not got rid of alternate manner, will not enumerate here.

If the base station has been terminal configuration three cell are called SCell1 and SCell2 and PCell, three cell all are in state of activation.The TDD UL/DL configuration that each cell is corresponding is respectively TDD UL/DL configuration 0, TDD UL/DL configuration 1 and TDD UL/DL configuration 2.OnDurationTimer, drx-InactivatityTimer and drx-RetransmissionTimer length are all got 5 PDCCH subframes, and HARQ RTT timer gets 10ms.Based on above-mentioned hypothesis, embodiments of the invention are as follows:

Embodiment one: the PDCCH number of sub-frames is that the relevant timer length of the DRX of length statistical unit is determined all with reference to PCell.

As shown in Fig. 7 A, establish t0 constantly, starting terminal onDurationTimer, onDurationTimer length is 5 PDCCH subframes, according to the statistics of the PDCCH subframe on PCell, onDurationTimer will be overtime after t0+5ms.Be about to overtime subframe at onDurationTimer, terminal is received the dispatch for the upper process S11 initial transmission of Sell1, starting terminal drx-InactivityTimer and for the HARQ RTT Timer of process S11.Drx-InactivityTimer length is 5 PDCCH subframes, according to the upper PDCCH subframe statistics of PCell, drx-InactivityTimer will be overtime after t0+10ms, but at t0+9ms, terminal is received the scheduling for the upper process S21 initial transmission of SCell2, according to commonDRX, need to restart this drx-InactivityTimer and startup this moment for the HARQ RTTTimer of process S21.at the HARQ of process S11 RTT Timer run duration, terminal does not successfully receive the packet of the upper process S11 of SCell1, terminal need to start the drx-RetransmissionTimer for this process, add up according to the PDCCH subframe on PCell, the drx-RetransmissionTimer of process S11 will be overtime after t0+21ms, before the drx-RetransmissionTimer of S11 is not overtime (t0+20ms), terminal has been received the retransfer scheduling signaling for S11, the drx-RetransmissionTimer that stop process S11 this moment starts the HARQ RTT timer for process S11 simultaneously.

The above describes as an example of the upper process S11 of SCell1 example and describes, and is similar to the S21 process.

Embodiment two: the PDCCH number of sub-frames is the minimum residential quarter of the interior PDCCH number of sub-frames of one of all residential quarter radio frames that the DRX timer length of length statistical unit determines all to be referenced as terminal configuration or configuration and activation.

Compare embodiment 1, the present embodiment need to increase by a step, namely need at first to judge the base station be in all residential quarters of terminal configuration or configuration and activation in the radio frames of one of which residential quarter the PDCCH number of sub-frames minimum, then in the DRX process, onDurationTimer, Drx-InactivityTimer and drx-RetransmissionTimer just need to add up timer length with the PDCCH subframe in this cell.

Hypotheses condition according to all embodiment of this patent, PDCCH subframe through judgement SCell1 is minimum, therefore in the present embodiment, in the DRX process, onDurationTimer, Drx-InactivityTimer and drx-RetransmissionTimer just need to be with the statistics of the PDCCH number of sub-frames in SCell1 timer length, rather than with the PDCCH number of sub-frames on PCell, Here it is and unique difference part of embodiment 1.

Embodiment three: the PDCCH number of sub-frames is the maximum residential quarter of the interior PDCCH number of sub-frames of one of all residential quarter radio frames that the DRX timer length of length statistical unit determines all to be referenced as terminal configuration or configuration and activation.

Similar to Example 2, compare embodiment 1, the present embodiment need to increase by a step, namely need at first to judge the base station be in all residential quarters of terminal configuration or configuration and activation in the radio frames of one of which residential quarter the PDCCH number of sub-frames maximum, then in the DRX process, onDurationTimer, Drx-InactivityTimer and drx-RetransmissionTimer just need to add up timer length with the PDCCH subframe in this cell.

According to the hypotheses condition of all embodiment of this patent, maximum through the PDCCH subframe of judgement PCell.Therefore in the present embodiment, in the DRX process, onDurationTimer, Drx-InactivityTimer and drx-RetransmissionTimer just need to add up timer length with the PDCCH number of sub-frames in PCell, so concrete DRX process and the embodiment 1 of the present embodiment are just the same.Here no longer repeat.

Embodiment four: the PDCCH number of sub-frames is that the DRX timer length of length statistical unit determines that equal reference base station is the longest residential quarter of timer Abstime that obtains according to PDCCH number of sub-frames statistics in all residential quarters of terminal configuration or configuration and activation.

As shown in Fig. 7 B, if t0 constantly, starting terminal onDurationTimer, onDurationTimer length is 5 PDCCH subframes, count from the onDurationTimer Startup time, according to 5 PDCCH subframe statistics, the absolute time of the onDurationTimer operation on SCell1 is the longest, therefore onDurationTimer is according to the statistics of the PDCCH subframe on SCell1, and onDurationTimer will be overtime after t0+11ms.Be about to overtime subframe at onDurationTimer, terminal is received the dispatch for the upper process S11 initial transmission of Sell1, starting terminal drx-InactivityTimer and for the HARQ RTT Timer of process S11.Drx-InactivityTimer length is 5 PDCCH subframes, count from the drx-InactivityTimer Startup time, according to 5 PDCCH subframe statistics, or the absolute time of the operation of the drx-InactivityTimer on SCell1 is the longest, therefore drx-InactivityTimer length is according to the upper PDCCH subframe statistics of SCell1, drx-InactivityTimer will be overtime after t0+16ms, but at t0+9ms, terminal is received the scheduling for the upper process S21 initial transmission of SCell2, according to commonDRX, need to restart this drx-InactivityTimer and startup this moment for the HARQ RTTTimer of process S21.at the HARQ of process S11 RTT Timer run duration, terminal does not successfully receive the packet of the upper process S11 of SCell1, terminal need to start the drx-RetransmissionTimer for this process, count from the drx-RetransmissionTimer Startup time, according to 5 PDCCH subframe statistics, or the absolute time of the operation of the drx-RetransmissionTimer on SCell1 is the longest, therefore add up according to the PDCCH subframe on SCell1, the drx-RetransmissionTimer of process S11 will be overtime after t0+21ms, before the drx-RetransmissionTimer of S11 is not overtime (t0+20ms), terminal has been received the retransfer scheduling signaling for S11, the drx-RetransmissionTimer that stop process S11 this moment starts the HARQ RTT timer for process S11 simultaneously.

Embodiment five: the PDCCH number of sub-frames is that the DRX timer length of length statistical unit determines that equal reference base station is the shortest residential quarter of timer Abstime that obtains according to PDCCH number of sub-frames statistics in all residential quarters of terminal configuration or configuration and activation.

Similar to Example 4, the length statistical-reference residential quarter of each DRX timer will be from counting from this timer Startup time here for unique difference, according to 4 PDCCH subframe statistics, the absolute time of the timer operation on which SCell is the longest, just selects which residential quarter as a reference.Hypotheses condition according to all embodiment of this patent, according to above-mentioned reference cell selection principle, in the present embodiment, in the DRX process, onDurationTimer, Drx-InactivityTimer and drx-RetransmissionTimer can select PCell as a reference.

If adopt the RRC signaling, form can be as follows:

Timer	The reference cell numbering
		onDurationTimer	PCell
drx-InactivityTimer	The cell number of SCell1
		drx-RetransmissionTimer	The cell number of SCell2

If adopt MAC CE mode, form can as shown in Fig. 7 C, should be noted that needing to introduce new LCID identifies this MAC CE.Wherein:
