Description
Technical field
The present invention relates to the communication of multiple radiotechnics when terminal coexistence; Relate in particular to a kind of (LTE that drills for a long time; Long Term Evolution) technology coexists as same terminal (UserEquipment, the time-division multiplex communication method and system in the time of UE) with 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 the LTE (upstream band (Band7UP: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.

In step S403; When UE confirms the data transmit-receive time (also can be called the LTE transmission time) of LTE for the coexistence time assignment information of this UE according to base station configuration; Can confirm the zero hour of the data transmit-receive time of LTE according to formula (2), the data transmit-receive time of LTE is kept the T_LTE duration.
[(SFN*10)+and subframe number] modulo (Tp)=(Toffset) modulo (Tp) formula (2)
Wherein, SFN (System Frame Number) is the System Frame Number of LTE, and subframe number is the subframe numbers of LTE, and modulo representes modulo operation.
After UE had confirmed the LTE data transmit-receive time, the time period between the data transmit-receive time of LTE finishes to begin to data transmit-receive time of LTE next time was the data transmit-receive time (also can be called the non-LTE transmission time) of other radiotechnicss.UE is according to the data transmit-receive time of the LTE that confirms and the data transmit-receive time of other radiotechnicss; Coordinate the data transmit-receive of LTE module and other radio modules; Promptly carry out the data transmit-receive of LTE, carry out the data transmit-receive of other radio modules in the data transmit-receive time of other radiotechnicss in the data transmit-receive time of LTE.This coordination can be accomplished by the control module shown in Fig. 1.
After having disposed coexistence time allocation of parameters, the LTE transfer of data of UE is only dispatched in the base station in the transmission time at LTE.Particularly; The base station can be according to coexistence time allocation periods and coexistence time migration; By confirming that with the terminal the identical mode zero hour of the data transmit-receive time of LTE confirms the zero hour in LTE transmission time, the LTE transfer of data of the LTE dispatch terminal in the transmission time that begins in this zero hour.
Carry out the data transmit-receive of LTE in the data transmit-receive time of LTE, specifically comprise:
1) (Physical DownlinkControl Channel PDCCH), stops to monitor PDCCH at non-LTE in the transmission time only to monitor Physical Downlink Control Channel in the transmission time at LTE;
2) only in LTE scheduling transceive data according to the base station in the transmission time, stop transceive data in the transmission time at non-LTE;
3) only send dispatch request (Scheduling Request) in the transmission time, stop to send dispatch request in the transmission time at non-LTE at LTE;
4) only LTE transmitting channel quality indication (CQI) information in the transmission time (Channel QualityIndicator, CQI), pre-coding matrix indication information (Precoding Matrix Index; PMI); Rank indication information (Rank Indicator, RI) and up feedback reference signal (Sounding ReferenceSymbols; SRS) etc. uplink information stops to send CQI/PMI/RI/SRS at non-LTE in the transmission time.
6) only measure in the transmission time, stop in the transmission time measuring at non-LTE at LTE.
The behavior of above data transmit-receive is specifically accomplished by the LTE module.
The 3rd embodiment
Fig. 4 is the time-division multiplex communication method flow diagram of not considering under the professional sudden and aperiodicity condition of transmitting; And the practical business transmission has sudden and aperiodicity; In time period as shown in Figure 6; The most of the time service throughput is illustrated average throughput all, and in the time, then has a burst throughput at T601 → T602.In view of the burst characteristic of business shown in Figure 6, shown in Figure 7 is the flow chart of the time-division multiplex communication method between another LTE module of present embodiment and other radio modules, and idiographic flow is:
S701, UE are to the time division multiplexing information of LTE base station report LTE and other radiotechnicss, same S401;
After said time division multiplexing information is received in S702, LTE base station; The coexistence time assignment information of UE configuration is confirmed as in decision-making; Comprising many group coexistence time allocation of parameters; Wherein one group coexistence of LTE base station activation time allocation of parameters, and will organize coexistence time allocation of parameters more and activate wherein that the indication information of one group of coexistence time allocation of parameters sends to UE;
Different is with S402, considers professional suddenly, and the base station can be the many groups of UE configuration coexistence time allocation of parameters.Such as, as shown in Figure 8, the base station is that UE has disposed two kinds of coexistence time methods of salary distribution, is respectively:
First kind of coexistence time method of salary distribution, corresponding coexistence time allocation of parameters be first group of coexistence time allocation of parameters (Tp1, Toffset1, T_LTE1/T_non_LTE1);
Second kind of coexistence time method of salary distribution, corresponding coexistence time allocation of parameters be second group of coexistence time allocation of parameters (Tp2, Toffset2, T_LTE2/T_non_LTE2).
When two groups of coexistence time allocation of parameters that the base station will dispose are notified UE, can carry the indication information of wherein a kind of time allocation of parameters that coexists of activation.This indication information can be to be specifically designed to the explicit indication information that indication activates any coexistence time allocation of parameters.Also can be the agreement agreement, acquiescence activates a certain group (as first group) coexistence time allocation of parameters of configuration, and what adopted this moment is the indication information of implicit expression, and the sequence number of the time allocation of parameters that promptly coexists is simultaneously as this indication information.
The LTE module is dispatched at the LTE that confirms according to the one group of coexistence time allocation of parameters that activates in the base station in the transmission time, with first embodiment.
S703, UE receive and preserve many groups of coexistence time allocation of parameters of base station configuration; Activate one group of coexistence time allocation of parameters according to indication information; Confirm the data transmit-receive time of LTE and the data transmit-receive time of other radiotechnicss according to this group coexistence time allocation of parameters; Carry out the data transmit-receive of LTE in the data transmit-receive time of LTE, carry out the data transmit-receive of other radiotechnicss, concrete same S403 in the data transmit-receive time of other radiotechnicss.
S704, base station be according to professional time-varying characteristics, needs to change current coexistence time during the method for salary distribution, activates another group coexistence time allocation of parameters, and send the instruction that activates this another group coexistence time allocation of parameters to UE;
Such as, the base station hopes to change into second kind of coexistence time method of salary distribution from first kind of coexistence time method of salary distribution, and base station notice UE activates second group of coexistence time allocation of parameters.Preferably, first group of coexistence of base station deexcitation simultaneously time allocation of parameters, perhaps, and according to the agreement agreement, after second group of coexistence of base station activation time allocation of parameters, the automatic deexcitation of first group of coexistence time assignment information.
After activating second group of coexistence time allocation of parameters, UE is dispatched at the LTE that confirms according to second group of coexistence time allocation of parameters in the base station in the transmission time LTE transfer of data.
S705, UE are according to the one group of coexistence time allocation of parameters that activates before the instruction deexcitation of base station; Activate another group coexistence time allocation of parameters then; Confirm LTE and other radiotechnics data transmit-receive times according to this another group coexistence time assignment information, and carry out corresponding data transmit-receive.
According to the time-division multiplex communication method between LTE shown in Figure 7 and other radiotechnicss; Base station and UE can change the data transmit-receive time of LTE and other radiotechnicss neatly according to traffic performance, thereby guarantee the communication quality of LTE module and other radio module high-qualitys.
Because coexistence is disturbed and is had sudden and noncontinuity in the equipment; Such as a UE who disposes LTE module and Bluetooth module; Have only when the Bluetooth module is opened; Just can have interference between LTE module and the Bluetooth module, in case and the Bluetooth 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 the time division multiplexing transmission, for cancelling the flow process of time-division multiplex communication, can be applied to above-mentioned each embodiment like Fig. 9, concrete steps are following:
S901, UE notice LTE base station coexistence interference eliminated;
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.
Definite message that S902, base station feedback cancellation (or claiming to discharge) coexistence time distribute;
After S903, UE receive the affirmation message of base station feedback, stop the time division multiplexing transmission of LTE and other radiotechnicss, by communicating by letter of each module of existing techniques in realizing and base station.
UE can delete the coexistence time assignment configuration of configuration before this.
