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, particularly relate to a kind of use Long Term Evolution (LTE, Long Term Evolution) module of technology and collaborative communication method when using the module of other radiotechnicss to be stored in same terminal (User Equipment, UE) and system.

Background technology

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

As the schematic diagram that Fig. 1 is a kind of terminal, employing three kinds of radiotechnicss in terminal S100, is the LTE module S101 using LTE technology respectively; Use the WLAN module S102 of WLAN (wireless local area network) (WLAN, the wireless local area networks) technology of IEEE Std 802.11 regulation and stipulation, i.e. wireless LAN station (WLAN STA); Use the bluetooth module S103 of bluetooth (Bluetooth) radiotechnics of IEEE Std 802.15 regulation and stipulation, these three modules also can be called LTE subset, WLAN subset and bluetooth subset.Three modules carry out radio communication with the opposite equip. corresponding to respective radiotechnics respectively, and wherein LTE module S101 and LTE base station (E-UTRANNodeB, eNB, also referred to as evolved base station) S104 carries out radio communication by air interface; WLAN module S102 and another WLAN STA equipment S105 carries out radio communication by air interface; Bluetooth module S103 and another bluetooth equipment S106 carries out radio communication by air interface.

In Fig. 1, be connected by the interface (inter-radiointerface) between the radiotechnics of terminal inner between three modules, such as be connected by first interface L101 between LTE module S101 with WLAN module S102, be connected by the second interface L102 between LTE module S101 with bluetooth module S103; Be connected by the 3rd interface L103 between WLAN module S102 with bluetooth module S103; Or three modules are controlled by a public control module S107.

In same terminal during the multiple different radiotechnics of configuration, in view of terminal volume is too little, certainly will mean be designed with two kinds or two or more radiotechnicss simultaneously terminal in, the space length between the module of this two or more radiotechnics (also referred to as radio module) is used to be separated by very near, such as several centimetres, also it is enough large that the space isolation namely between the antenna port that uses of this two or more radiotechnics cannot design, if thus when causing the interval between the frequency that the various radiotechnicss in same terminal use large not, due to band outward leakage (Out of bandemission), spurious emissions (Spurious emissions) and receiver block reasons such as (Blocking), when one of them radio module is launched, by the reception of another radio module of interference, vice versa.And this interference cannot be eliminated by existing filter, can affect the communication quality of each radio module.In literary composition, above-mentioned interference is referred to as " in equipment mutual interference ".

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

For the terminal S100 shown in Fig. 1, 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 ISM frequency band, and Bluetooth uses the 2.4GHz ~ 2.497GHz frequency range in ISM frequency band.ISM frequency band is just in time adjacent with the upstream band (Band7 UP:2.5GHz ~ 2.57GHz) of frequency band 7 with the frequency band 40 (Band40:2.3GHz ~ 2.4GHz) of LTE, as shown in Figure 2.If therefore LTE module S101 uses TDD (Time Division Duplex, time division duplex) pattern and use Band40, and when the interval between the operating frequency of the operating frequency of LTE module S101 and WLAN module S102, bluetooth module S103 is less, will mutually disturb between LTE module S101 and WLAN module S102, bluetooth module S103.If LTE module S101 uses FDD (Frequency Division Duplex, Frequency Division Duplexing (FDD)) pattern and use Band7, as shown in Figure 2, due to downstream bands and the ISM frequency band a good distance off of LTE Band7, therefore the downlink reception of LTE module S101 is not disturbed in the up transmitting of WLAN module S102/ bluetooth module S103, but because the upstream band of LTEBand7 and ISM frequency band adjoin, when interval between the operating frequency and the operating frequency of WLAN module S102/ bluetooth module S103 of LTE module S101 is less, the up transmitting of LTE module S101 is by descending just receipts of interference WLAN module S102/ bluetooth module S103.

The existence of " in equipment mutual interference " can reduce the communication quality of the radio module both sides interfered with each other, to be applied as example shown in Fig. 3, intelligent terminal S302 is configured with LTE module and WLAN module, wherein LTE module is communicated with LTE base station S301 by the first air interface L301, WLAN module is by the second air interface L302 and WLAN AP (Access Point, access point) communication, the working frequency points of LTE module is 2.390GHz, and WLAN module is operated on WLAN channel (channel) 12.412GHz.Work as synchronization, LTE module carries out downlink reception and simultaneously WLAN module just in time sends data to WLAN AP time, the downlink reception of LTE module is disturbed by WLAN module, vice versa, namely, when WLAN module receives the data of WLAN AP, can be disturbed by the LTE module of carrying out up transmission simultaneously, finally affect the business experience of user.

More than analyze visible, when multiple different radiotechnics coexists in equipment, in equipment, mutual interference is by reducing the communication quality of this multiple different radiotechnics, affects the communication experiences of user.And along with the continuous lifting of requirements of mobile subscribers, in same terminal, configure multiple different radiotechnics the market demand and application prospect are increasing, therefore must seek effective measures reduction and even avoid mutual interference in equipment, guarantee the business experience that mobile subscriber is good.

Embodiment

For making the object, technical solutions and advantages of the present invention clearly understand, hereinafter will be described in detail to embodiments of the invention by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.

Wen Zhong, module is a logical concept, and as LTE module refers to the logic module of the software and hardware structure using LTE technology, WLAN module refers to the logic module of the software and hardware structure using WLAN technology.When actual physics realizes, disparate modules also can realize on same chip or hardware.

For reducing the power consumption of terminal, in LTE standard, have employed discontinuous reception (DiscontinuousReception, DRX) mechanism.DRX mechanism specifies like this:

LTE base station (also referred to as base station) is LTE module configuration DRX, specifically comprises and is configured to lower parameter, duration timer (onDurationTimer); DRX inactivity timer (drx-InactivityTimer); Medium education contention resolved timer (mac-ContentionResolutionTimer); DRX retransmission timer (drx-RetransmissionTimer), DRX cycle (DRX-cycle) etc., above-mentioned all base stations are that UE configuration parameter all assigns the value of putting corresponding parameter, the duration (in literary composition if no special instructions, herewith explaining) of configuration timer is referred to as configured timer.

As shown in Figure 4, open from an onDurationTimer, timing definition between onDurationTimer unlatching is next time a DRX cycle, namely DRX cycle is the running time (or claiming timing, i.e. duration as shown in Figure 4) of onDurationTimer and the summation in potential DRX transmission time as shown in Figure 4.

According to the DRX parameter of base station configuration, UE carries out discrete data receiver and/or transmission, take into account the power consumption of UE and the needs of UE business transmission, according to the business transmitted data amount of UE reality and the scheduling of base station, the time that UE carries out non-continuous data reception and/or transmission is uncertain.A kind of possible DRX discontinuous transmission time diagram as shown in Figure 5, in this schematic diagram, in a DRX cycle, there are three discontinuous transmission times, wherein the discontinuous transmission time 501 is the duration, and within the potential DRX transmission time, also there are two discontinuous transmission times, i.e. discontinuous transmission time 502 and the discontinuous transmission time 503, the discontinuous transmission time within the potential DRX transmission time may comprise in following six kinds of times any one or a few:

1, after the upstream or downstream head that drx-InactivityTimer running time: UE receives base station passes scheduling, the follow-up possibility proceeding transfer of data is larger, UE needs to keep a period of time (drx-InactivityTimer) to monitor base station, prepares to receive the follow-up scheduling in base station;

2, drx-RetransmissionTimer running time: the equipment of this timer is the descending re-transmission in order to ensure UE.Due to HARQ (Hybrid Automatic Repeat Request, down mixing self-retransmission request) feature of process, UE can for receiving HARQ process initiation Loop Round Trip Time timer (RTT timer) of downlink data after receiving downlink data dispatching, if UE does not successfully decode to received data before RTT timer time-out, just need to start drx-RetransmissionTimer 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 and trigger, when UE carries out Stochastic accessing, after sending Msg3, need to wait for that the response of Msg4 (Message4, message four) is replied in base station.

4, uplink scheduling request (Scheduling Request, SR) waits for the time of base station in response after sending: SR is used for before UE uplink data sending, and request base station is dispatched it.After sending SR, UE needs the response waiting for base station, namely waits for that base station is that the mandate of UE dispatching uplink is to send upstream data.

5, the uplink retransmission stand-by period: in upstream data process of transmitting, UE may send due to data the successful respond unsuccessfully not receiving base station, needs to wait for that uplink retransmission is carried out in the scheduling of base station.

6, the non-competing Stochastic accessing downlink data stand-by period: non-competing Stochastic accessing generally for and triggers UE and obtain uplink synchronous, then can downlink data receiving, and after non-competing random process completes, UE waits for that the descending scheduling of base station is with downlink data receiving.

Visible, because the discontinuous transmission time in a DRX cycle is uncertain, namely the reception of LTE data and/or the time of transmission uncertain, when LTE and other radiotechnicss to coexist in same terminal and operating frequency close to time, the reception and/or the transmission that inevitably will LTE and other radiotechnicss be made at synchronization may to carry out data, thus cause mutually disturbing between the transmission/reception module of LTE and other radiotechnicss.

Step 3, LTE module determines DRX activationary time according to the scheduling of described DRX parameter and described LTE base station;

In a DRX cycle, the DRX activationary time that LTE module is determined comprises the running time of duration timer, when having at least one timer to open in DRX inactivity timer and DRX retransmission timer, also comprise the running time of the described timer of unlatching; Or

In a DRX cycle, the DRX activationary time that LTE module is determined comprises the running time of duration timer, when having at least one timer to open in DRX inactivity timer, DRX retransmission timer and medium education contention resolved timer, also comprise the running time of the described timer of unlatching.

The running time of above-mentioned one or more timer can overlap.

Compared with prior art, the DRX activationary time of the present embodiment no longer comprise wait for base station in response after uplink scheduling request sends time, uplink retransmission stand-by period and non-competing Stochastic accessing downlink data stand-by period, alternatively, do not comprise the running time of medium education contention resolved timer, therefore can reduce the uncertainty of DRX activationary time, be conducive to the normal transfer of data of WLAN module.

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

Wherein:

If described time division multiplexing information is the time devided modulation information of LTE and WLAN, then base station is with reference to described time devided modulation information, further can also according to carrier policy, final decision determines the time division multiplexing configuration of LTE and WLAN, then is configured DRX parameter according to described time division multiplexing configuration.

Base station receives described time division multiplexing information, after LTE module configuration DRX parameter, before cancellation time multiplexed transmission, namely within the T2 time period as shown in Figure 6, the time division multiplexing configuration of LTE and the WLAN that base station is determined according to institute's decision-making and DRX parameter scheduling LTE module;

LTE module determines DRX activationary time according to the DRX parameter of configuration and the scheduling of base station, LTE module carries out transfer of data in DRX activationary time, and WLAN module carries out transfer of data in non-DRX activationary time, described non-DRX activationary time to refer in DRX cycle the remaining time except DRX activationary time.

In time period T1 and T3 not starting time multiplexed transmission, base station and LTE module work according to existing DRX mechanism.

Because mutual interference in equipment has sudden and noncontinuity, such as one is configured with the UE of LTE module and WLAN module, only has when WLAN module is opened, just can there is interference between LTE module and WLAN module, and once WLAN module is closed, mutual interference will not exist yet.Therefore, when UE judges that mutual interference does not exist, LTE module carries out time multiplexed transmission with regard to not needing between other radio modules again, can cancel time multiplexed transmission by informing base station, concrete:

S603, UE cancel time multiplexed transmission by LTE module notice eNB;

By the interface between disparate modules as shown in Figure 1 or control module S107, UE can know whether WLAN closes, such as UE judges that WLAN module is closed, then cancel time multiplexed transmission by LTE module notice eNB.

After eNB is notified, do not need the time division multiplexing information considering that in step S601, UE reports again when dispatching LTE module, namely base station only needs according to configured DRX parameter scheduling LTE module.Or preferably, base station performs step S604.

S604, base station are LTE module configuration DRX parameter, this time do not need to consider mutual interference in UE during configuration DRX parameter, such as, can be configured to the DRX before carrying out time multiplexed transmission and configure, or in prior art, other do not consider the DRX configuration of mutual interference in UE.

Based on Fig. 6, the time division multiplexing of following two kinds of concrete LTE and WLAN can be adopted to configure, respectively as illustrated in fig. 7 and fig. 10.

Configure based on each time division multiplexing below, when illustrating that the present embodiment LTE and other radio modules coexist, the DRX configuration of base station and scheduling behavior, and in UE, LTE module and other radio modules carry out the method for time multiplexed transmission.

The first time division multiplexing configures

Sudden and the aperiodicity that business is transmitted is not considered in this kind of time division multiplexing configuration, for specific transactions, within a period of time, according to class of business and characteristic, can obtain demand average time of business transmission.In such as a period of time, be ensure LTE module service transmission quality, LTE business data packet be sent completely next LTE business datum start to send between maximum time interval, can as the maximum of non-LTE transmission time; For ensureing WLAN module service transmission quality, WLAN business data packet be sent completely next WLAN business data packet start to send between maximum time interval, can as the maximum of LTE transmission time.

Figure 7 shows that time devided modulation (the i.e. time division multiplexing configuration) schematic diagram of a kind of LTE and WLAN, wherein, LTE transmission time and WLAN transmission time constitute a time division multiplexing cycle.

After base station receives the LTE module of S601 report and the time division multiplexing information of WLAN module, can according to the strategy of operator, the time devided modulation (i.e. the time division multiplexing configuration of LTE and WLAN) adopting LTE and WLAN is as shown in Figure 7 determined in decision-making.

Base station according to the time devided modulation of LTE and WLAN as shown in Figure 7, be LTE module configuration DRX.Base station is that the DRX parameter of LTE module configuration comprises: duration timer, DRX inactivity timer, DRX retransmission timer, DRX cycle and DRX opening time deviant (drxStartOffset).

Base station is according to the time devided modulation of LTE and WLAN as shown in Figure 7 when configuring above-mentioned DRX parameter, and concrete configuration is as shown in the S802 of Fig. 8:

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

2, configure DRX duration timer duration (i.e. duration) and be less than or equal to the LTE transmission time shown in S801.

3, the duration configuring DRX inactivity timer and DRX retransmission timer is the duration being less than the LTE transmission time.

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

After LTE module receives the upstream or downstream head biography scheduling of base station, the follow-up possibility proceeding transfer of data is larger, drx-InactivityTimer will be started, keep a period of time (running time of drx-InactivityTimer) to monitor base station, prepare to receive the follow-up scheduling in base station.Therefore during base station scheduling LTE module, can according to LTE transmission time and the drx-InactivityTimer configured duration, the drx-InactivityTimer started after ensureing last first biography scheduling can run complete within the LTE transmission time, namely no longer carry out head in first duration of LTE base station before the LTE transmission time terminates and pass scheduling, this first duration equals the duration of the DRX inactivity timer configured.Thus guarantee the transmission time of WLAN.

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

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

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

LTE module starts DRX duration timer when judging that some subframes of some radio frames are satisfied with formula (1), is also the time started of the LTE transmission time shown in Fig. 8.

LTE module determines DRX activationary time according to the DRX configuration of S802 and the scheduling of base station, particularly, DRX activationary time comprises the running time of duration timer (onDurationTimer), when DRX inactivity timer (drx-InactivityTimer) starts, also comprise the running time of DRX inactivity timer (drx-InactivityTimer).

The opening time of DRX retransmission timer (drx-RetransmissionTimer) is uncertain, therefore the transmission time of WLAN is likely taken, but consider relative to data head biography, the re-transmission of data is small probability events, in addition, wlan system possesses certain error correcting capability, and therefore when there being the downlink data of small probability to retransmit generation, DRX activationary time can further include the running time of DRX retransmission timer (drx-RetransmissionTimer).

Further, if any one run duration in two or three timers above-mentioned, UE has initiated the Stochastic accessing competed, and during all timer expiries, competition process does not also terminate, namely medium education contention resolved timer (mac-ContentionResolutionTimer) is also in operation, to guarantee the success of described Stochastic accessing.Mac-ContentionResolutionTimer likely takies the transmission time of WLAN running time, but consider that above-mentioned event is small probability event, in addition, wlan system possesses certain error correcting capability, therefore DRX activationary time can also comprise mac-ContentionResolutionTimer running time, also can not comprise.

LTE module is according to the described DRX activationary time determined, transfer of data is carried out in DRX activationary time, specifically comprise, LTE module only monitors Physical Downlink Control Channel (PhysicalDownlink Control Channel in activationary time, PDCCH), according to the scheduling transceiving data of PDCCH; LTE module only sends the information such as SRS/CQI/PMI/PI in activationary time; LTE module stops sending SR at inactivation time; LTE module, in inactivation time, except the Stochastic accessing that causes of switching of base station instruction, stops initiating random access procedure.

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

Fig. 7 is the time devided modulation schematic diagram of LTE and the WLAN under the sudden and aperiodicity condition not considering that business is transmitted, and practical business transmission has sudden and aperiodicity, in time period as shown in Figure 9, the throughput of most of the time business is all illustrated average throughput, and within T901 → T902 time, then have a burst throughput.In view of the burst characteristic of business shown in Fig. 9, Figure 10 illustrates the time devided modulation schematic diagram of another kind of LTE and WLAN, in the time devided modulation schematic diagram of shown LTE and WLAN, ensure LTE transmission time, flexible transmission time and ensure that the WLAN transmission time constitutes a time division multiplexing cycle, wherein ensure the LTE transmission time and ensure the average throughput that the WLAN transmission time may be used for ensureing as shown in Figure 9, and when LTE or WLAN business burst, the flexible transmission time can be configured to transmission time of LTE or WLAN neatly, to guarantee the transmission of burst service data.As shown in Figure 10, if the flexible transmission time is configured to the LTE transmission time, then ensure that LTE transmission time and flexible transmission time constitute the maximum LTE transmission time, otherwise, if the flexible transmission time is configured to the WLAN transmission time, then ensure that WLAN transmission time and flexible transmission time constitute the maximum WLAN transmission time.

Base station receives the LTE module of S601 report and the time division multiplexing information of WLAN module, further according to the strategy of operator, as the time devided modulation (i.e. the time division multiplexing configuration of LTE and WLAN) of LTE and WLAN is as shown in Figure 10 determined in decision-making.Base station, according to the time devided modulation of LTE and WLAN as shown in Figure 10, is LTE module configuration DRX parameter.

2, configuration DRX duration timer duration (i.e. duration) is less than or equal to the guarantee LTE transmission time as shown in S1101.

The DRX that the time devided modulation of LTE and the WLAN of base station according to S1101 and S1102 configure dispatches LTE module.Specifically comprise:

Base station in guarantee LTE transmission time (time period T1101 → T1102 as shown in figure 11), or, ensureing to dispatch LTE module, as when there being burst transfers of data in the maximum LTE transmission time that LTE transmission time and flexible transmission time are formed.

After LTE module receives the upstream or downstream head biography scheduling of base station, the follow-up possibility proceeding transfer of data is larger, drx-InactivityTimer will be started, keep a period of time (running time of drx-InactivityTimer) to monitor base station, prepare to receive the follow-up scheduling in base station.Therefore during base station scheduling LTE module, according to the drx-InactivityTimer duration ensureing the LTE transmission time and configure, the drx-InactivityTimer started after ensureing last first biography scheduling can run complete within the maximum LTE transmission time, that is: before the guarantee LTE transmission time terminates, or no longer carry out head in the first duration before the maximum LTE transmission time that guarantee LTE transmission time and flexible transmission time are formed terminates and pass scheduling, this first duration equals the duration of the DRX inactivity timer configured.Thus guarantee the transmission time of WLAN.
