Description

The time-division multiplex communication method and system of multiple radiotechnics when terminal coexistence

Technical field

The present invention relates to the communication for coordination of multiple radiotechnics when terminal coexistence; Relate in particular to a kind of use Long Term Evolution (LTE; Long Term Evolution) module of technology is stored in same terminal (User Equipment, collaborative communication method in the time of UE) and system with the module of using other radiotechnicss.

Background technology

Along with the development of radiotechnics, increasing radiotechnics begins to be widely used, especially in order to satisfy the multiple communication requirement of terminal client, in same intelligent terminal, with using two or more different radiotechnics simultaneously.

Like Fig. 1 is a kind of sketch map of terminal, has used three kinds of radiotechnicss among the S100 of terminal, is to use the LTE module S101 of LTE technology respectively; Use the WLAN module S102 of WLAN (WLAN, the wireless local area networks) technology of IEEE Std 802.11 regulation and stipulations, i.e. wireless lan station (WLAN STA); Use the bluetooth module S103 of bluetooth (Bluetooth) radiotechnics of IEEE Std 802.15 regulation and stipulations, these three modules also can be called LTE subset, WLAN subset and bluetooth subset respectively.Three modules respectively and separately pairing opposite equip. of radiotechnics are carried out radio communication, and wherein LTE module S101 and LTE base station (E-UTRANNodeB, eNB are also referred to as evolved base station) S104 carries out radio communication through air interface; WLAN module S102 and another WLAN STA equipment S105 carry out radio communication through air interface; Bluetooth module S103 and another bluetooth equipment S106 carry out radio communication through air interface.

Among Fig. 1; Link to each other through the interface (inter-radiointerface) between the radiotechnics of terminal inner between three modules; Link to each other through the first interface L101 such as between LTE module S101 and the WLAN module S102, link to each other through the second interface L102 between LTE module S101 and the bluetooth module S103; Link to each other through the 3rd interface L103 between WLAN module S102 and the bluetooth module S103; Perhaps, three modules are controlled by a public control module S107.

In the same terminal during the multiple different radiotechnics of configuration; Seeing that terminal volume is too little; Certainly will mean in the terminal that is designed with two kinds or two or more radiotechnics simultaneously; Use the space length between the module (being also referred to as radio module) of this two or more radiotechnics to be separated by very near; Such as several centimetres, also promptly the space isolation between the employed antenna port of this two or more radiotechnics can't design enough big, thereby if cause when the interval between the employed frequency of various radiotechnicss in the same terminal is big inadequately; Because outer (Out of bandemission), spurious emissions (Spurious emissions) and the receiver revealed of band blocks reasons such as (Blocking); When one of them radio module was launched, with the reception of disturbing another radio module, vice versa.And this interference can't can influence the communication quality of each radio module through existing filter elimination.In the literary composition above-mentioned interference is referred to as " coexistence is disturbed in the equipment ".

Use other radio modules of other radiotechnicss of use of Long Term Evolution (LTE) technology

With terminal S100 shown in Figure 1 is example; WLAN and Bluetooth use " industry, science and medical treatment (Industrial Scientific and Medical; be called for short ISM) " frequency band (2.4GHz～2.5GHz); Wherein WLAN uses the 2.4GHz～2.4835GHz frequency range in the ISM frequency band, and Bluetooth uses the 2.4GHz～2.497GHz frequency range in the ISM frequency band.The ISM frequency band just in time with the frequency band 40 of LTE (upstream band (the Band7 UP:2.5GHz～2.57GHz) adjacent, as shown in Figure 2 of Band40:2.3GHz～2.4GHz) and frequency band 7.If therefore LTE module S101 uses TDD (Time Division Duplex; Time division duplex) pattern and use Band40; And the interval between the operating frequency of the operating frequency of LTE module S101 and WLAN module S102, bluetooth module S103 is hour, between LTE module S101 and WLAN module S102, the bluetooth module S103 with mutual interference mutually.If LTE module S101 uses FDD (Frequency Division Duplex; FDD) pattern and use Band7; As shown in Figure 2; Because downstream bands and the ISM frequency band a good distance off of LTE Band7, so the up emission of WLAN module S102/ bluetooth module S103 do not disturb the descending reception of LTE module S101, but owing to upstream band and the ISM frequency band of LTEBand7 adjoins; Interval between the operating frequency of the operating frequency of LTE module S101 and WLAN module S102/ bluetooth module S103 hour, the up emission of LTE module S101 will be disturbed the descending just receipts of WLAN module S102/ bluetooth module S103.

The existence of " coexistence is disturbed in the equipment " can reduce the radio module both sides' that interfere with each other communication quality; With the example that is applied as shown in Figure 3; Intelligent terminal S302 disposes LTE module and WLAN module; Wherein the LTE module is communicated by letter with LTE base station S301 through the first air interface L301, and the WLAN module is through the second air interface L302 and WLAN AP (Access Point, access point) communication; The working frequency points of LTE module is 2.390GHz, and it is last that the WLAN module is operated in WLAN channel (channel) 12.412GHz.Work as synchronization; The LTE module is carried out descending reception and simultaneously the WLAN module is just in time when WLAN AP sends data, and the descending reception of LTE module is disturbed by the WLAN module, and vice versa; Promptly; When the WLAN module receives the data of WLAN AP, can be carried out the LTE module of up transmission simultaneously and disturbed, finally influenced user's business experience.

More than analyze visiblely, when multiple different radiotechnics coexisted as in the equipment, the communication quality that will reduce this multiple different radiotechnics was disturbed in coexistence in the equipment, influences user's communications experience.And along with the continuous lifting of requirements of mobile subscribers; The market demand and the application prospect of the multiple different radiotechnics of configuration are increasing in same terminal; Therefore must seek the effective measures reduction even avoid coexistence interference in the equipment, guarantee the business experience that the mobile subscriber is good.

Embodiment

For making the object of the invention, technical scheme and advantage clearer, hereinafter will combine accompanying drawing that embodiments of the invention are elaborated.Need to prove that under the situation of not conflicting, embodiment among the application and the characteristic among the embodiment be combination in any each other.

In the literary composition, module is a logical concept, is meant the logic module of using the technological software and hardware structure of LTE like the LTE module, and the WLAN module is meant the logic module of the software and hardware structure that uses the WLAN technology.When actual physics was realized, disparate modules also can be realized on same chip or hardware.

For reducing the power consumption at terminal, discontinuous reception (DiscontinuousReception, DRX) mechanism have been adopted in the LTE standard.DRX mechanism is to stipulate like this:

LTE base station (also abbreviating the base station as) is LTE block configuration DRX, specifically comprises being configured to down parameter duration timer (onDurationTimer); The non-Active Timer of DRX (drx-InactivityTimer); Medium access control competition solves timer (mac-ContentionResolutionTimer); DRX retransmission timer (drx-RetransmissionTimer); DRX cycle (DRX-cycle) etc.; Above-mentioned all base stations are the value that corresponding parameter is put in the equal assignment of UE configuration parameter, are meant configuration length of timer (Wen Zhongru does not have specified otherwise, herewith explains) like the configuration timer.

As shown in Figure 4; Open from an onDurationTimer; Timing definition between onDurationTimer opens next time is a DRX cycle; Be that DRX cycle is the summation in running time (or claim timing, duration promptly as shown in Figure 4) with the potential DRX transmission time as shown in Figure 4 of onDurationTimer.

DRX parameter according to base station configuration; UE carries out discrete Data Receiving and/or transmission; Take into account the needs of the professional transmission of power consumption and UE of UE, the professional data amount transmitted and the scheduling of base station actual according to UE, UE carries out that non-continuous data receives and/or the time of transmission is uncertain.As shown in Figure 5 is the discontinuous transmission time sketch map of a kind of possible DRX, in this sketch map, in the DRX cycle; There are three discontinuous transmission times; The wherein discontinuous transmission time 501 is the duration, and in the transmission time, also has two discontinuous transmission times at potential DRX; Be discontinuous transmission time 502 and discontinuous transmission time 503, possibly comprise in following six kinds of times any one or a few in the discontinuous transmission time of potential DRX in the transmission time:

1, after drx-InactivityTimer running time: UE receives that the upstream or downstream of base station are first and passes scheduling; The follow-up possibility of proceeding transfer of data is bigger; UE need keep a period of time (drx-InactivityTimer) that the base station is monitored, and prepares to receive the follow-up scheduling in base station;

2, drx-RetransmissionTimer running time: the equipment of this timer is in order to guarantee the descending re-transmission of UE.Because HARQ (Hybrid Automatic Repeat Request; The down mixing self-retransmission request) characteristics of process; UE is meeting Loop Round Trip Time timer of HARQ process initiation (RTT timer) for receiving downlink data after receiving downlink data dispatching; If UE does not successfully decode to received data before RTT timer is overtime, start drx-RetransmissionTimer with regard to needs and wait for that base station scheduling retransmits.

3, mac-ContentionResolutionTimer running time: this process is by the Msg3 (Message3 of random access procedure; Message three) send triggering, after UE inserts at random, sends Msg3; Need to wait for the response of base station answer Msg4 (Message4, message four).

4, uplink scheduling request (Scheduling Request, SR) send the time that base station in response is waited in the back: SR is used for before the UE uplink data sending, and dispatch it the request base station.After having sent SR, UE need wait for the response of base station, waits for that promptly the base station is that the mandate of UE dispatching uplink is to send upstream data.

5, the uplink retransmission stand-by period: in the upstream data process of transmitting, UE possibly not receive the successful respond of base station because data are sent failure, and uplink retransmission is carried out in the scheduling that needs to wait for the base station.

6, non-competingly insert the downlink data stand-by period at random: the non-competing access at random obtained uplink synchronous in order to trigger UE usually, then can downlink data receiving, and after non-competing random process was accomplished, UE waited for that the descending scheduling of base station is with downlink data receiving.

It is thus clear that; Because the discontinuous transmission time in a DRX cycle is uncertain; The time of reception and/or transmission that is the LTE data is uncertain; When LTE and other radiotechnicss coexist as in the same terminal and operating frequency near the time, inevitably will make LTE and other radiotechnicss possibly carry out the reception and/or the transmission of data at synchronization, can mutual interference mutually between the transmission/receiver module of LTE and other radiotechnicss thereby cause.

First embodiment

There is the problem of mutual interference mutually to coexisting as LTE module and at least a other radio modules in the terminal; Present embodiment is based on DRX mechanism; Propose a kind of LTE module and and this LTE module between other radio modules of exist disturbing carry out the method for time-division multiplex communication, comprising:

Step 1, LTE module are reported the time division multiplexing information of said LTE module and said other radio modules to the LTE base station;

After step 2, LTE base station receive said time division multiplexing information, send to the LTE module for LTE block configuration DRX parameter and with said DRX parameter;

In this step, after LTE received the base station time division multiplexing information, the time division multiplexing configuration that can make a strategic decision earlier and confirm LTE module and other radio modules was configured to terminal configuration DRX parameter according to said time division multiplexing again;

Time division multiplexing configuration can be in the following configuration mode a kind of:

First kind: multiplexing cycle of configuring time division, and LTE transmission time and at least one in the transmission time of non-LTE, the said time division multiplexing cycle equals LTE transmission time and non-LTE transmission time sum;

Second kind: multiplexing cycle of configuring time division and flexible transmission time; And guarantee the LTE transmission time and guarantee at least one in the transmission time of non-LTE that the said time division multiplexing cycle equals to guarantee LTE transmission time, flexible transmission time and guarantees non-LTE transmission time sum.

The LTE base station is that the DRX parameter of terminal configuration comprises: duration timer, the non-Active Timer of DRX, DRX retransmission timer, DRX cycle and DRX opening time deviant.

If what adopted the LTE base station is first kind of time division multiplexing configuration, be configured to terminal configuration DRX parameter according to this time division multiplexing, comprising:

The configuration DRX cycle is the time division multiplexing cycle;

The duration of configuration DRX duration timer is the duration that is less than or equal to the LTE transmission time;

The duration of the non-Active Timer of configuration DRX and the duration of DRX retransmission timer are the duration less than the LTE transmission time.

If what adopted the LTE base station is second kind of time division multiplexing configuration, be configured to terminal configuration DRX parameter according to this time division multiplexing, comprising:

The configuration DRX cycle is the time division multiplexing cycle;

The duration of configuration DRX duration timer is to be less than or equal to the duration that guarantees the LTE transmission time;

The duration of the non-Active Timer of configuration DRX and the duration of DRX retransmission timer are less than the duration that guarantees the LTE transmission time.

Can dispose according to current mode for other DRX parameters such as DRX opening time deviant.

Correspondingly, when dispatch the terminal according to the configuration of said time division multiplexing and DRX parameter the LTE base station, comprising:

As adopt the configuration of first kind of time division multiplexing, the LTE base station is at LTE dispatch terminal in the transmission time; Further, can also comprise: no longer carry out head in first duration of LTE base station before the LTE transmission time finishes and pass scheduling, the duration of the non-Active Timer of DRX that this first duration equals to dispose.

As adopt the configuration of second kind of time division multiplexing, the LTE base station is guaranteeing LTE in the transmission time, perhaps at the maximum LTE that guarantees LTE transmission time and flexible transmission time formation dispatch terminal in the transmission time; Further; Can also comprise: the LTE base station is before the assurance LTE transmission time finishes; Perhaps no longer carry out head in first duration before the maximum LTE transmission time that guarantees LTE transmission time and flexible transmission time formation finishes and pass scheduling, the duration of the non-Active Timer of DRX that this first duration equals to dispose.

Step 3, the LTE module is confirmed the DRX activationary time according to the scheduling of said DRX parameter and said LTE base station;

In a DRX cycle; The DRX activationary time that the LTE module is confirmed comprises the running time of duration timer; When in non-Active Timer of DRX and DRX retransmission timer, having at least one timer to open, also comprise the running time of the said timer of unlatching; Perhaps

In a DRX cycle; The DRX activationary time that the LTE module is confirmed comprises the running time of duration timer; When in the non-Active Timer of DRX, DRX retransmission timer and medium access control competition solution timer, having at least one timer to open, also comprise the running time of the said timer of unlatching.

Can overlap the running time of above-mentioned one or more timers.

Compared with prior art; The DRX activationary time of present embodiment comprises no longer that the uplink scheduling request sends that the time of base station in response is waited in the back, uplink retransmission stand-by period and non-competing is inserted the downlink data stand-by period at random; Alternatively; Do not comprise the running time that medium access control competition solves timer, therefore can reduce the uncertainty of DRX activationary time, help the normal transfer of data of WLAN module.

Step 4, LTE module are carried out transfer of data in the DRX activationary time, other radio modules carry out transfer of data in non-DRX activationary time.

Wherein:

The LTE module is carried out transfer of data in the DRX activationary time, comprising:

The LTE module is only sent one or more in the following information in the DRX activationary time: up feedback reference signal (SRS), channel quality indication (CQI) information (CQI), pre-coding matrix indication information (PMI) and rank indication information (RI);

The LTE module stops to send the uplink scheduling request in non-DRX activationary time;

The LTE module the access at random that the switching of indicating except the base station causes, stops to initiate random access procedure in non-DRX activationary time.

After the DRX activationary time finished, the LTE module can notify other radio modules can begin transfer of data through mutual interface or control module.

The LTE module of present embodiment stops to send the uplink scheduling request and except the access at random that the switching of base station indication causes, stops to initiate random access procedure in non-DRX activationary time.Prior art does not have this restriction, and the uncertainty that can reduce the DRX activationary time so is set, and helps the normal transfer of data of WLAN module.

Table 1

The LTE module can know that WLAN carries out the time of transfer of data and the time division multiplexing information of needs according to interface between the disparate modules as shown in Figure 1 or control module, report the LTE module the LTE base station under the resident LTE Serving cell.

After said time division multiplexing information was received in S602, base station, the time division multiplexing configuration of LTE module and other radio modules was confirmed in decision-making, is configured to LTE block configuration DRX parameter according to the time division multiplexing of confirming again;

Corresponding to S601, if said time division multiplexing information is that UE need carry out the time division multiplexing information transmitted, then the base station can be confirmed the time division multiplexing configuration of LTE and WLAN according to the carrier policy decision-making, according to said time division multiplexing configuration the DRX parameter is configured again; Wherein, carrier policy as can be LTE module institute transport service quality of service requirement (Quality of Service, QoS); The LTE systematic function; Agreement that operator under operator and other radio modules reaches or the like, perhaps

If said time division multiplexing information is the information of other radiotechnicss of coexistence in the UE equipment and/or the business information of other radiotechnicss; Then the base station is according to said time division multiplexing information; Confirm that in conjunction with carrier policy and/or the decision-making of agreement regulation the time division multiplexing of LTE and WLAN disposes, according to said time division multiplexing configuration the DRX parameter is configured again; Perhaps

If the time assignment information that said time division multiplexing information is LTE and WLAN; Then the base station is with reference to said time assignment information; Further can also be according to carrier policy, final decision is confirmed the time division multiplexing configuration of LTE and WLAN, according to said time division multiplexing configuration the DRX parameter is configured again.

Said time division multiplexing information is received in the base station; After LTE block configuration DRX parameter; Before cancellation time division multiplexing transmission, promptly at T2 as shown in Figure 6 in the time period, make a strategic decision according to institute in the base station, the time division multiplexing of the LTE that confirms and WLAN disposes and the DRX parameter is dispatched the LTE module;

The LTE module is confirmed the DRX activationary time according to the DRX parameter of configuration and the scheduling of base station; The LTE module is carried out transfer of data in the DRX activationary time; And the WLAN module is carried out transfer of data in non-DRX activationary time, and said non-DRX activationary time is meant in the DRX cycle the remaining time except that the DRX activationary time.

In the time period T1 and T3 that do not start the time division multiplexing transmission, base station and LTE module are according to existing DRX mechanism works.

Because coexistence is disturbed and is had sudden and noncontinuity in the equipment; Such as a UE who disposes LTE module and WLAN module, have only when the WLAN module is opened, just can there be interference between LTE module and the WLAN module; In case and the WLAN module is closed, coexistence is disturbed and also will not existed.Therefore, disturb when not existing when UE judges coexistence, the LTE module just do not need again and other radio modules between carry out time division multiplexing and transmitted, can informing base station cancellation time division multiplexing transmit, concrete:

S603, UE are through the transmission of LTE module notice eNB cancellation time division multiplexing;

UE can know whether WLAN closes through interface between the disparate modules as shown in Figure 1 or control module S107, closes such as UE judgement WLAN module, then through the transmission of LTE module notice eNB cancellation time division multiplexing.

After eNB is notified, when scheduling LTE module, do not need the time division multiplexing information of considering that again UE reports among the step S601, promptly the base station only need be according to the DRX parameter scheduling LTE module that is disposed.Perhaps, preferred, base station execution in step S604.

S604, base station are LTE block configuration DRX parameter, need not consider when this disposes the DRX parameter that coexistence is disturbed in the UE, for example, can be configured to carry out the preceding DRX configuration of time division multiplexing transmission, or other DRX that do not consider that coexistence is disturbed in the UE dispose in the prior art.

Based on Fig. 6, can adopt the time division multiplexing configuration of following two kinds of concrete LTE and WLAN, respectively like Fig. 7 and shown in Figure 10.

Below based on the configuration of each time division multiplexing, when the coexistence of present embodiment LTE and other radio modules be described, the DRX configuration and the scheduling behavior of base station, and the interior LTE module of UE and other radio modules carry out the method that time division multiplexing is transmitted.

First kind of time division multiplexing configuration

Sudden and the aperiodicity of professional transmission is not considered in the configuration of this kind time division multiplexing, for specific transactions, in a period of time, can obtain demand average time of professional transmission according to class of business and characteristic.In a period of time, be to guarantee LTE modular service transmission quality, LTE business data packet is sent and is accomplished to the maximum time of next LTE business datum between beginning to send at interval, can be used as the maximum in non-LTE transmission time; For guaranteeing WLAN modular service transmission quality, a WLAN business data packet is sent the maximum time interval that is accomplished between the next WLAN business datum packet start transmission, can be used as the maximum in LTE transmission time.

Time for a kind of LTE and WLAN shown in Figure 7 is distributed (being multiplexing configuration of time-division) sketch map, and wherein, LTE transmission time and WLAN transmission time have constituted a time division multiplexing cycle.

After the time division multiplexing information of LTE module and WLAN module of S601 report is received in the base station, can be according to the strategy of operator, decision-making confirms to adopt the time distribution (time division multiplexing that is LTE and WLAN disposes) of LTE as shown in Figure 7 and WLAN.

The base station according to time of LTE as shown in Figure 7 and WLAN distribute, be LTE block configuration DRX.The base station is that the DRX parameter of LTE block configuration comprises: duration timer, the non-Active Timer of DRX, DRX retransmission timer, DRX cycle and DRX opening time deviant (drxStartOffset).

When the base station was distributed in the above-mentioned DRX parameter of configuration according to time of LTE as shown in Figure 7 and WLAN, concrete configuration was shown in the S802 of Fig. 8:

1, the configuration DRX cycle is time division multiplexing cycle as shown in Figure 7 (T801 → T804);

2, configuration DRX duration timer duration (being the duration) is less than or equal to the LTE transmission time shown in the S801.

3, the duration of configuration non-Active Timer of DRX and DRX retransmission timer is the duration less than the LTE transmission time.

The base station is according to the DRX parameter that time distributes and S802 the disposed scheduling LTE module of LTE shown in the S801 and WLAN.Specifically comprise: the base station is only in (the scheduling LTE module of time period T801 → T803 as shown in Figure 8 and time period T804 → T806) of LTE in the transmission time.

After the LTE module receives the first biography scheduling of upstream or downstream of base station; The follow-up possibility of proceeding transfer of data is bigger; To start drx-InactivityTimer; Keep a period of time (running time of drx-InactivityTimer) that the base station is monitored, prepare to receive the follow-up scheduling in base station.Therefore during base station scheduling LTE module; Can be according to LTE transmission time and the drx-InactivityTimer duration that is disposed; The drx-InactivityTimer that starts after the last first biography scheduling of assurance can move in the transmission time at LTE and finish; Be no longer to carry out head in first duration of LTE base station before the LTE transmission time finishes to pass scheduling, the duration of the non-Active Timer of DRX that this first duration equals to dispose.Thereby guarantee the transmission time of WLAN.

Base station and LTE module can be confirmed the time started and the DRX duration timer opening time in LTE transmission time according to formula (1) respectively:

[(SFN*10)+subframe?number]modulo(DRX-Cycle)＝drxStartOffset(1)

Wherein SFN (System Frame Number) is a radio frame number, and subframe number is a subframe numbers, and modulo representes modulo operation, and DRX-Cycle is a DRX cycle, and drxStartOffset is a DRX opening time deviant.

The LTE module is judged startup DRX duration timer when some subframes of some radio frames are satisfied with formula (1), also is the time started in LTE transmission time shown in Figure 8.

The LTE module is confirmed the DRX activationary time according to the DRX configuration of S802 and the scheduling of base station; Particularly; The DRX activationary time comprises the running time of duration timer (onDurationTimer); When the non-Active Timer of DRX (drx-InactivityTimer) starts, also comprise the running time of the non-Active Timer of DRX (drx-InactivityTimer).

The opening time of DRX retransmission timer (drx-RetransmissionTimer) is uncertain; Therefore might take the transmission time of WLAN, but consider that the re-transmission of data is small probability events with respect to the first biography of data; In addition; Wlan system possesses certain error correcting capability, and therefore when the downlink data of small probability retransmitted generation, the DRX activationary time can further include the running time of DRX retransmission timer (drx-RetransmissionTimer).

Further; If any run duration in above-mentioned two or three timers; UE has initiated the access at random of competition, and during all timer expiries, competition process does not also finish; Be that medium access control competition solves timer (mac-ContentionResolutionTimer) also in operation, saidly insert successfully at random guaranteeing.Mac-ContentionResolutionTimer might take the transmission time of WLAN running time; But consider that above-mentioned incident is a small probability event; In addition; Wlan system possesses certain error correcting capability, so the DRX activationary time can also comprise mac-ContentionResolutionTimer running time, also can not comprise.

The LTE module is according to said definite DRX activationary time; In the DRX activationary time, carry out transfer of data, specifically comprise, the LTE module is only monitored Physical Downlink Control Channel (PhysicalDownlink Control Channel in activationary time; PDCCH), according to the scheduling transceive data of PDCCH; The LTE module is only sent information such as SRS/CQI/PMI/PI in activationary time; The LTE module stops to send SR at non-activationary time; The LTE module the access at random that the switching of indicating except the base station causes, stops to initiate random access procedure in non-activationary time.

The WLAN module is carried out transfer of data according to the work start-up time and the knocking-off time (or run duration) of LTE module or control module notice in non-DRX activationary time.

Fig. 7 is a time distribution sketch map of not considering LTE and WLAN under the sudden and aperiodicity condition of professional transmission; And the practical business transmission has sudden and aperiodicity; In time period as shown in Figure 9; The most of the time service throughput is illustrated average throughput all, and in the time, then has a burst throughput at T901 → T902.Burst characteristic in view of business shown in Figure 9; Figure 10 example time of another kind of LTE and WLAN distribute sketch map; Shown in time of LTE and WLAN distribute in the sketch map; Guarantee LTE transmission time, flexible transmission time and guarantee that the WLAN transmission time constituted a time division multiplexing cycle, wherein guarantee the LTE transmission time and guarantee that the WLAN transmission time can be used to guarantee average throughput as shown in Figure 9, and when LTE or WLAN business burst; The flexible transmission time can be configured to the transmission time of LTE or WLAN neatly, to guarantee the transmission of burst service data.Shown in figure 10; If the flexible transmission time is configured to the LTE transmission time; Guarantee that then LTE transmission time and flexible transmission time have constituted the maximum LTE transmission time; Otherwise,, guarantee that then WLAN transmission time and flexible transmission time have constituted the maximum WLAN transmission time if the flexible transmission time is configured to the WLAN transmission time.

The LTE module of S601 report and the time division multiplexing information of WLAN module are received in the base station, further strategy according to operator, as the time distribution (being the time division multiplexing configuration of LTE and WLAN) of making a strategic decision and confirming LTE shown in figure 10 and WLAN.The base station was distributed according to the time of LTE shown in figure 10 and WLAN, was LTE block configuration DRX parameter.

The base station is that the DRX parameter of LTE block configuration comprises: duration timer; The non-Active Timer of DRX; The DRX retransmission timer; DRX cycle and DRX opening time deviant (drxStartOffset).

The base station according to time of LTE shown in figure 10 and WLAN when being distributed in the above-mentioned DRX parameter of configuration, concrete configuration is shown in the S1102 of Figure 11:

1, the configuration DRX cycle is time division multiplexing cycle shown in figure 10 (T1101 → T1104);

2, configuration DRX duration timer duration (being the duration) is less than or equal to the assurance LTE transmission time shown in S1101.

The base station is according to the DRX that time distributes and S1102 the disposed scheduling LTE module of LTE shown in the S1101 and WLAN.Specifically comprise:

The base station guarantee the LTE transmission time (in the time period T1101 shown in figure 11 → T1102), perhaps, guaranteeing that the maximum LTE of LTE transmission time with flexible transmission time formation dispatches the LTE module in the transmission time, as when burst transfers of data is arranged.

After the LTE module receives the first biography scheduling of upstream or downstream of base station; The follow-up possibility of proceeding transfer of data is bigger; To start drx-InactivityTimer; Keep a period of time (running time of drx-InactivityTimer) that the base station is monitored, prepare to receive the follow-up scheduling in base station.Therefore during base station scheduling LTE module; According to guaranteeing LTE transmission time and the drx-InactivityTimer duration that is disposed; The drx-InactivityTimer that starts after the last first biography scheduling of assurance can move in the transmission time at maximum LTE and finish; That is: before the assurance LTE transmission time finishes; Perhaps no longer carry out head in first duration before the maximum LTE transmission time that guarantees LTE transmission time and flexible transmission time formation finishes and pass scheduling, the duration of the non-Active Timer of DRX that this first duration equals to dispose.Thereby guarantee the transmission time of WLAN.

The LTE module is confirmed the DRX activationary time according to the scheduling of the DRX of S1102 configuration and base station, and concrete DRX activationary time comprises duration timer (onDurationTimer) running time; When the non-Active Timer of DRX (drx-InactivityTimer) moves, also comprise the running time of the non-Active Timer of DRX (drx-InactivityTimer).

When DRX retransmission timer (drx-RetransmissionTimer) moves, can also comprise the running time of DRX retransmission timer (drx-RetransmissionTimer).

If any run duration in above-mentioned two or three timers; The LTE module has been initiated the access at random of competition; And during three timer expiries, competition process does not also finish, i.e. medium access control competition solves timer (mac-ContentionResolutionTimer) also in operation; The DRX activationary time also comprises mac-ContentionResolutionTimer running time, saidly inserts successfully at random guaranteeing.

The LTE module is carried out transfer of data in the DRX activationary time, specifically comprise: the LTE module is only monitored PDCCH in activationary time, according to the scheduling transceive data of PDCCH; The LTE module is only sent control informations such as SRS/CQI/PMI/PI in activationary time; The LTE module stops to send SR at non-activationary time; The LTE module the access at random that the switching of indicating except the base station causes, stops to initiate random access procedure in non-activationary time.

The WLAN module is carried out transfer of data according to said definite DRX activationary time in non-DRX activationary time.
