Description

Interference avoidance method, system and mobile device

Technical field

The present invention relates to the communications field, in particular to a kind of interference avoidance method, system and mobile device.

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 kinds even two or more different radiotechnics simultaneously.

Like Fig. 1 is a kind of sketch map that uses the terminal equipment of three kinds of radiotechnicss simultaneously; In this terminal equipment S100; Three kinds of radiotechnicss have been used in design, are to use the subset 101 (or claiming submodule) of Long Term Evolution (LTE, Long Term Evolution) technology respectively; Use the subset 102 of WLAN (WLAN, the Wireless Local AreaNetworks) technology of IEEE Std 802.11 regulation and stipulations, i.e. wireless lan station (WLAN STA); Use the subset 103 of bluetooth (Bluetooth) radiotechnics of IEEE Std 802.15 regulation and stipulations.Three subsets of terminal equipment the S100 respectively and separately pairing opposite equip. of radiotechnics carry out radio communication, and wherein S101 and S104LTE eNB (E-UTRANNodeB, evolved base station) carry out radio communication through air interface; Another WLAN STA equipment of S102 and S105 carries out radio communication through air interface; Another Bluetooth equipment of S103 and S106 carries out radio communication through air interface.

Among Fig. 1, S101, S102 links to each other through the interface (inter-radiointerface) between the radiotechnics between three subsets of S103, links to each other through L101 such as between S101 and the S102, links to each other through L102 between S101 and the S103; Link to each other through L103 between S102 and the S103, perhaps three subsets are controlled by a public control appliance S107.

The multiple different radiotechnics of configuration in the same terminal equipment, however in view of the terminal equipment volume too little, certainly will mean to be designed with simultaneously in two kinds even the two or more radiotechnics terminal equipment; Use the space length between the subset of different radiotechnicss to be separated by very near; Such as several centimetres, also promptly use enough big that space isolation between the employed antenna port of each subset of different radiotechnicss can't design, thereby cause: if when each radiotechnics in the same terminal equipment is used adjacent frequency band; Because outer reveal (the Out of band emission) of band; Spurious emissions (Spuriousemissions), receiver blocks reasons such as (Blocking), when one of them radio technology modules is launched; With the reception of disturbing another radio technology modules; Vice versa, and this interference can't eliminate through existing filter again, thereby influence the communication quality of each radio technology modules.

With terminal equipment S100 shown in Figure 1 is example; WLAN and Bluetooth use " industry, science and medical treatment (IndustrialScientific 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.Therefore if S101 uses TDD (Time Division Duplex, time division duplex) pattern and uses Band40, so between S101 and S102, the S103 with mutual interference mutually.If 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 descending reception of S101 is not disturbed in the up emission of S102/S103; But owing to upstream band and the ISM frequency band of LTE Band7 adjoins, so the up emission of S101 will disturb the descending of S102/S103 just to receive.

Phase mutual interference meeting between the subset of use different radio power technology reduces this radio-based electronic devices both sides' communication quality; With the example that is applied as shown in Figure 3; S302 is an intelligent terminal, disposes LTE subset that uses the LTE technology and the bluetooth subset that uses the Bluetooth technology, and wherein the LTE subset is communicated by letter with LTE base station S301 through air interface L301; The bluetooth subset is communicated by letter with the opposite end bluetooth earphone through air interface L302; The working frequency points of LTE subset is 2.390GHz, and the bluetooth subset is worked with the frequency hopping mode between 2.402GHz～2.410GHz, works as synchronization; The LTE subset carries out descending reception and simultaneously the bluetooth subset is just in time when the opposite end bluetooth earphone sends data, and the descending reception of LTE subset is disturbed by the bluetooth subset.And the data that the bluetooth subset is sent to the opposite end bluetooth earphone to be descending receptions from the LTE subset obtain; Because the interference of bluetooth subset causes LTE subset downlink data receiving efficiency lowly to influence the efficient of bluetooth subset to opposite end bluetooth earphone transmission data conversely again, finally influences user's business experience.Vice versa, i.e. the up transmission of LTE subset disturbs the reception of bluetooth subset also can influence two communication links of L301 and L302 simultaneously, finally influences user's business experience.

More than analyze visible, when different radiotechnicss is communicated by letter in same terminal equipment simultaneously, between these radiotechnicss with the phase mutual interference, thereby reduce the communication quality of these radiotechnicss, influence 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 equipment; Therefore the business experience that the mobile subscriber is good is guaranteed in the phase mutual interference in the time of must seeking the effective measures reduction even avoid different radiotechnicss in same terminal equipment, to communicate by letter.

When in same terminal equipment, communicating by letter simultaneously to radiotechnicss different in the correlation technique; Between these radiotechnicss with the phase mutual interference; Thereby reduce the communication quality of these radiotechnicss, influence the problem that user's communications is experienced, do not propose effective solution at present as yet.

Notify first subset to begin to disturb the indication information of avoiding;

Sign is guaranteed the information of speech business quality.

Wherein, suppose that radio frames of first subset comprises 10 sub-frame, the example of sub-frame configuration bitmap is like " 01,100,011,000,000,111,010 0000000100 ".This sub-frame configuration bitmap has write down the distribution condition that each subframe in the radio frames of per 3 first subsets is kept for first subset and second subset.A sub-frame of correspondence position in the corresponding radio frames of each (bit) expression in the bitmap of sub-frame configuration wherein; First subframe of from left to right representing per 3 radio frames first frames successively; Second sub-frame of first frame ... The 9th sub-frame of the 3rd frame, the tenth sub-frame of the 3rd frame.During distribution condition that the physical record subframe is reserved, can be provided with 1 for this place, position subframe of expression is to distribute to the subframe of first subset, 0 for this place, position subframe of expression be to distribute to the subframe of second subset.

In implementation process, first subset carries out the signal transmission according to subframe configuration information on the subframe of keeping for first subset, stop signal transmission on the subframe of keeping for second subset.Difference according to subframe configuration information; The technological means that adopts is also incomplete same, for example, and state one; When the subframe configuration information is the sub-frame configuration bitmap index of sub-frame of uplink and descending sub frame configuration bitmap or correspondence; The time deviation of the first subset basis and opposite equip. agreement is carried out the signal transmission on the subframe of keeping for first subset, stop signal transmission on the subframe of keeping for second subset.Wherein, time deviation refers to the time difference between the zero-time of a radio frames of zero-time and second subset of a radio frames of first subset.Comprise following operations:

If time deviation is the radio frames of the first subset SFN#0 and the time deviation between second subset; Then first subset is in the P that satisfies a SFN%P=0 radio frames; In corresponding sub-frame configuration bitmap, keep for and carry out the signal transmission on the subframe of first subset, in corresponding sub-frame configuration bitmap, keep for stop signal transmission on the subframe of second subset;

When if time deviation is radio frames and the time deviation between second subset of the first subset SFN#X; Then first subset is in the P that satisfies a SFN%P=X radio frames; In corresponding sub-frame configuration bitmap, keep for and carry out the signal transmission on the subframe of first subset, in corresponding sub-frame configuration bitmap, keep for stop signal transmission on the subframe of second subset.

Wherein, P=L/N, L are the length of sub-frame configuration bitmap, and N is the length of the first subset radio frames, i.e. sub-frame of uplink that radio frames comprised of first subset and descending sub frame number.

Again for example; State two; When the subframe configuration information is sub-frame of uplink configuration bitmap (or corresponding sub-frame of uplink configuration bit index of the picture) or descending sub frame configuration bitmap (or corresponding descending sub frame configuration bit index of the picture); First subset is known complete sub-frame configuration bitmap according to institute sub-frame of uplink configuration bitmap or descending sub frame configuration bitmap and HARQ sequential, the time deviation of the first subset basis and opposite equip. agreement; In the complete sub-frame configuration bitmap of correspondence, keep on the subframe of first subset and carry out the signal transmission, in the complete sub-frame configuration bitmap of correspondence, keep for stop signal transmission on the subframe of second subset.Comprise following operation:

If time deviation is the radio frames of the first subset SFN#0 and the time deviation between second subset; Then first subset is in the P that satisfies a SFN%P=0 radio frames; In the complete sub-frame configuration bitmap of correspondence, keep on the subframe of first subset and carry out the signal transmission, in the complete sub-frame configuration bitmap of correspondence, keep for stop signal transmission on the subframe of second subset;

Wherein, P=L/N, L are the length of sub-frame of uplink configuration bitmap or descending sub frame configuration bitmap, N be up configuration bitmap or descending sub frame configuration bitmap the number of sub-frame of uplink or descending sub frame in the corresponding TDD uplink-downlink configuration.

Again for example; State three, when the subframe configuration information is when notifying first subset to begin to disturb the indication information of avoiding, first subset is according to receiving the sub-frame configuration bitmap that reports opposite equip. before the subframe configuration information; The perhaps sub-frame configuration bitmap of basis and opposite equip. agreement; The time deviation of the first subset basis and opposite equip. agreement is carried out the signal transmission on the subframe of keeping for first subset, stop signal transmission on the subframe of keeping for second subset.Comprise following operations:

If first subset reports opposite equip.; Or first subset and opposite equip. agreement be that sub-frame of uplink disposes bitmap with descending sub frame; And time deviation is the radio frames of the first subset SFN#0 and the time deviation between second subset; Then first subset is in the P that satisfies a SFN%P=0 radio frames; In corresponding sub-frame configuration bitmap, keep for and carry out the signal transmission on the subframe of first subset, in corresponding sub-frame configuration bitmap, keep for stop signal transmission on the subframe of second subset; Wherein, P=L/N, L are the length of sub-frame configuration bitmap, and N is the length of the first subset radio frames, i.e. sub-frame of uplink that radio frames comprised of first subset and descending sub frame number.

If first subset reports opposite equip.; Or first subset and opposite equip. agreement be that sub-frame of uplink disposes bitmap with descending sub frame; And when time deviation is radio frames and the time deviation between second subset of the first subset SFN#X; Then first subset is in the P that satisfies a SFN%P=X radio frames; In corresponding sub-frame configuration bitmap, keep for and carry out the signal transmission on the subframe of first subset, in corresponding sub-frame configuration bitmap, keep for stop signal transmission on the subframe of second subset.Wherein, P=L/N, L are the length of sub-frame of uplink and descending sub frame configuration bitmap, and N is the length of the first subset radio frames, i.e. sub-frame of uplink that radio frames comprised of first subset and descending sub frame number.

If first subset reports opposite equip.; Or first subset and opposite equip. agreement be sub-frame of uplink configuration bitmap or descending sub frame configuration bitmap; And time deviation is the radio frames of the first subset SFN#0 and the time deviation between second subset; Then first subset is at first according to sub-frame of uplink configuration bitmap or descending sub frame configuration bitmap; Know complete sub-frame configuration bitmap with the HARQ sequential; Then in the P that satisfies a SFN%P=0 radio frames, in the complete sub-frame configuration bitmap of correspondence, keep on the subframe of first subset and carry out the signal transmission, in the complete sub-frame configuration bitmap of correspondence, keep for stop signal transmission on the subframe of second subset; Wherein, P=L/N, L are the length of sub-frame of uplink configuration bitmap or descending sub frame configuration bitmap, N be sub-frame of uplink configuration bitmap or descending sub frame configuration bitmap the number of sub-frame of uplink or descending sub frame in the corresponding TDD uplink-downlink configuration.

If first subset reports opposite equip.; Or first subset and opposite equip. agreement be sub-frame of uplink configuration bitmap or descending sub frame configuration bitmap; And when time deviation is radio frames and the time deviation between second subset of the first subset SFN#X; Then first subset is at first according to sub-frame of uplink configuration bitmap or descending sub frame configuration bitmap; Know complete sub-frame configuration bitmap with the HARQ sequential; Then in the P that satisfies a SFN%P=X radio frames, in the complete sub-frame configuration bitmap of correspondence, keep on the subframe of first subset and carry out the signal transmission, in the complete sub-frame configuration bitmap of correspondence, keep for stop signal transmission on the subframe of second subset; Wherein, P=L/N, L are the length of sub-frame of uplink configuration bitmap or descending sub frame configuration bitmap, N be up configuration bitmap or descending sub frame configuration bitmap the number of sub-frame of uplink or descending sub frame in the corresponding TDD uplink-downlink configuration.

Again for example; State four; When the subframe configuration information is guaranteed the information of speech business quality for characterizing; First subset carries out the signal transmission on opposite equip. disposes to the up semi-persistent scheduling subframe of first subset and/or descending semi-persistent scheduling subframe, stop signal transmission on opposite equip. disposes to the up semi-persistent scheduling SPS subframe of first subset and/or other subframes outside the descending SPS subframe.Wherein, Sign guarantees that the information of speech business quality comprises: terminal equipment and opposite equip. agreement; Up/descending SPS subframe of calculating gained according to up/descending SPS configuration information is to keep for the subframe of first subset, and other subframes are to keep for the subframe of second subset.

In one embodiment; If with LTE subset and Bluetooth subset is example; When first subset is the LTE subset; When second subset is the Bluetooth subset, keep for the subframe of LTE subset need satisfy LTE HARQ sequential, and/or keep for the subframe of Bluetooth subset need satisfy LTE HARQ sequential.

Wherein, Preferably; When the time deviation information is not specified the zero-time of specific LTE radio frames and after this radio frames zero-time; And between this radio frames zero-time during the zero-time of a Tesco window of the minimum Bluetooth equipment of time deviation, disturb avoid request message be between LTE subset and the Bluetooth subset time deviation information and computing time employed LTE radio frames during deviation information SFN #X.

Wherein, preferred, it is one of following that time deviation information can comprise:

When the Bluetooth subset is main equipment; Time deviation between adjustment of Bluetooth subset and the LTE subset; Make that time deviation between the two is the value in the least interference time deviation interval; Perhaps the Bluetooth subset is a slave unit, and the time deviation between Bluetooth subset and the LTE subset is the value in the least interference time deviation interval, the time deviation information that this moment, the LTE subset reported;

When the Bluetooth subset is a slave unit, perhaps the Bluetooth subset is a main equipment, but the Bluetooth subset is not adjusted and the LTE subset between time deviation, the time deviation information that this moment, the LTE subset reported.

Above-mentioned time deviation refers to after the initial moment of the radio frames of LTE subset SPN#X, and the time difference between the zero-time of a Tesco window of the minimum Bluetooth subset of time deviation between this initial moment.

During enforcement; If also dispose the 3rd subset of employing the 3rd radiotechnics or the 4th subset of the 4th radiotechnics or the like in the mobile device; Can disturb setting and the adjusting of avoiding to each subset in the mobile device successively; For example, adopt said method preferentially first subset and second subset to be disturbed and avoid regulating, and then first subset and the 3rd subset disturbed avoid adjusting; Interference avoidance process method between its processing method and first subset and second subset is similar, does not do at this and gives unnecessary details.Interference avoidance process method between the 4th subset or other subsets also adopts similar processing mode.

Need to prove that the transmission of signal described in the embodiment of the invention like no specified otherwise, comprises that signal receives and sends, the signal of mentioning in the embodiment of the invention comprises various data and control information.

The embodiment of the invention is technological (such as WLAN with LTE and ISM relevant radio; When Bluetooth) coexisting as in the same terminal equipment is example; Especially coexisting as in the same terminal equipment with LTE and Bluetooth is example; Interference avoidance method when embodiment of the invention different radio technology co-existence is described; The interference avoidance method that need to prove the embodiment of the invention is applicable to solution LTE and other radiotechnicss too, the interference when perhaps Bluetooth and other radiotechnicss coexist as in the same terminal equipment.

When two kinds of radiotechnicss of LTE and Bluetooth coexist as in the same terminal equipment; The typical case, application scenarios is as shown in Figure 3 the most widely; The bluetooth subset transmitting audio data among the S302 wherein; The bluetooth subset receives the LTE subset from LTE eNB (S301) speech data sends to bluetooth earphone (S303), sends to the LTE subset to the speech data that receives from bluetooth earphone (S303), sends to LTE eNB (S301) by the LTE subset via L301 then.Between LTE subset and the LTE eNB (S301), except transmitting above-mentioned speech data, can also transmit other non-speech datas, as the file transport service (File Transfer Protocol, FTP), mail etc.

Bluetooth uses SCO (Synchronous Connection-Oriented is synchronously towards connecting) link or eSCO link transmission speech data.SCO or eSCO link transmission data have cyclophysis on time-domain, be example with the data packet format EV3 of Bluetooth protocol specification defined, and when using the eSCO link transmission, the data transmit-receive window sequential of eSCO EV3 is as shown in Figure 5.Fig. 5 with Bluetooth as main equipment (Master); There are 6 Bluetooth time slots (slot) to be example in the data eSCO transmitting-receiving window (Tesco window); Have 3 transmission/receiving slots to (Tx/Rxinstance) in the eSCO transmitting-receiving window; Each slot duration 0.625ms (millisecond), therefore a Tesco window duration is 3.75ms.When the Bluetooth main equipment sends data to opposite end slave unit (Slave); A packet can only send and receive the response data from Slave at 3 Tx/Rx instance in the eSCO transmitting-receiving window; If all send failure at these 3 Tx/Rx instance; This packet can be dropped, and what promptly transmit in each Tesco window of Bluetooth all is different data.

No matter LTE adopts fdd mode or tdd mode; All adopt radio frames (frame) structure in 10ms cycle; Especially for tdd mode; For satisfying different uplink and downlink timeslot allocation ratios, have 7 kinds of different TDD uplink-downlink configuration at present, and the design of 7 kinds of TDD uplink-downlink configuration can guarantee all to repeat with the 10ms wireless frame period.Like Fig. 6 is the sequential chart of TDD uplink-downlink configuration 1; Wherein comprise descending pilot frequency time slot (Downlink Pilot Time Slot in the special subframe; DwPTS), protection at interval (Guard Period, GP), uplink pilot time slot (Uplink Pilot Time Slot; What UpPTS), can look in embodiments of the present invention is descending sub frame.

Through analyzing the cyclophysis of Bluetooth SCO or eSCO link sequential; And the cyclophysis of LTE radio frame transmission; Can find to adopt SCO or eSCO to carry out voice data transmission when the Bluetooth subset of same terminal equipment; And also carry out speech data in this while LTE subset; When perhaps speech data was with other non-speech data transmission, the Data Receiving of Bluetooth receiving slot (Rx) was disturbed in the emission of LTE sub-frame of uplink, otherwise perhaps the transmission of the data of Bluetooth sending time slots (Tx) disturbs the disturbed condition of the Data Receiving of LTE descending sub frame to have cycle repeatability.Sequential with the data transmit-receive window sequential of the eSCO EV3 of Bluetooth shown in Figure 5 and LTE TDD uplink-downlink configuration 1 shown in Figure 6 is an example; As shown in Figure 7; When the initial moment of the initial moment and LTE TDD uplink-downlink configuration 1 one radio frames of a Tesco window of Bluetooth subset aligns, provided the disturbed condition between LTE and the Bluetooth (being called for short BT) like Fig. 8.Among Fig. 8; LTE all on/descending sub frame all is in data to be sent out/receipts state (embodiment of the invention is claimed full load condition); Data of Bluetooth subset only wrap in the Tesco window and receive/send out once; And the Tx/Rx instance that the Bluetooth subset at first selects all can not produce between the LTE subset and Bluetooth subset in the Tesco window interference carries out data and sends out/receive; If there is not such Tx/Rx instance; The Tx/Rx instance that then selects the Bluetooth subset can not disturb LTE subset downlink data to receive carries out data and sends out/receive, if there is not such Tx/Rx instance, then selects first Tx/Rx instance (working mechanism of Bluetooth main equipment).

Among Fig. 8; Disturbed condition between LTE subset and the Bluetooth subset is every to be repeated at a distance from the 30ms cycle; Similarly, under other LTE TDD uplink-downlink configuration situation, the disturbed condition between LTE subset and the Bluetooth subset also is to repeat in every separated 30ms cycle.Interference between LTE subset and the Bluetooth subset has periodicity and repeats characteristic; And for other radiotechnicss; Such as land wireless access technology (Universal Terrestrial Radio Access; UTRA), also have fixing wireless frame period, therefore and the interference that has between the radiotechnics of fixed cycle send window such as Bluetooth also have cycle repeatability.Based on above-mentioned discovery; The embodiment of the invention proposes in a kind of same terminal equipment; When the different radio power technology is communicated by letter simultaneously, avoid the method for the interference between the different radiotechnics, wherein; At least dispose the equipment one (being first subset mentioned above) that adopts radiotechnics one (being first radiotechnics mentioned above) in the terminal equipment; Adopt the equipment two (being second subset mentioned above) of radiotechnics two (being second radiotechnics mentioned above), equipment one communicates with the same opposite equip. (describe for convenient, be called equipment three below) of radiotechnics one that adopts; Equipment two communicates with the same opposite equip. (describe for convenient, be called equipment four below) of radiotechnics two that adopts.The method flow diagram of the method that provides for the embodiment of the invention like Fig. 9, idiographic flow is:

Need explanation, S903 and the S904 sequencing that has no time.

Interference when coexisting as in the same terminal equipment with LTE subset (equipment one) and Bluetooth subset (equipment two) below is an example, lifts embodiment and specifies method provided by the invention.Wherein, the opposite equip. of communicating by letter with equipment one is LTE eNB, and the opposite end communication equipment of communicating by letter with equipment two is for using the bluetooth earphone of Bluetooth technology.

LTE belongs to different radiotechnicss with Bluetooth; LTE subset and Bluetooth subset in the same terminal equipment have system time separately; Wherein the system time of LTE subset is by the opposite equip. LTE eNB decision of communication with it; And the system time of Bluetooth subset depends on the role of this Bluetooth subset when communication, if this Bluetooth subset is a main equipment; Then system time is determined by this Bluetooth subset, otherwise is determined by the opposite end communication equipment.When LTE subset and Bluetooth subset coexist as in the same terminal equipment; Interference between LTE and the Bluetooth has characteristic of cycle repetition; Seeing that different time deviation between the system time of the system time of LTE subset and Bluetooth subset, LTE and the Bluetooth interference characteristic in one-period is different.

Like Figure 10 is the time deviation graph of a relation of Bluetooth eSCO EV3 and LTE TDD uplink-downlink configuration 1; In embodiments of the present invention, the time difference between the zero-time of the Tesco window of the zero-time of the radio frames of definition LTE and Bluetooth is " time deviation (time offset) ".Under the different time deviation, LTE is different with the disturbed condition between the Bluetooth between LTE and the Bluetooth.For a kind of specific LTE TDD uplink-downlink configuration; The embodiment of the invention is defined in again in all time deviations; Make the minimum time deviation of interference between pairing LTE and the Bluetooth be " least interference time deviation "; Form one is depicted as under 7 kinds of LTE TDD uplink-downlink configuration, LTE all on/descending sub frame all is in data sends out/the receipts state least interference time deviation when the Bluetooth subset is main equipment in the terminal equipment.

Form one

Embodiment one

LTE and Bluetooth are under the different time deviation; LTE is different with the disturbed condition between the Bluetooth; When the Bluetooth subset in the terminal equipment is main equipment; The system time of Bluetooth is provided with by the Bluetooth main equipment, so the Bluetooth subset can adjust the time deviation between itself and the LTE subset, under this time deviation; Can promptly adjust this time deviation and be " least interference time deviation " so that the interference between LTE subset and the Bluetooth subset is minimum.Then according to LTE and the disturbance state of Bluetooth under " least interference time deviation "; Design LTE sub-frame configuration bitmap; In LTE sub-frame configuration bitmap, the part subframe is configured to keep for LTE to carry out the signal transmission, and the residue sub-frame configuration is carried out the signal transmission for keeping for Bluetooth.

Minimum time deviation with under the various TDD uplink-downlink configuration shown in the form one is an example, according to the disturbance state between LTE and the Bluetooth in each minimum time deviation interval, and design LTE sub-frame configuration bitmap.Figure 11 for LTETDD uplink-downlink configuration 1 and Bluetooth when the least interference time deviation is 0.875ms; One is disturbed the disturbance state figure (interference between LTE and the Bluetooth repeated with the 30ms cycle) in the repetition period; In 3 LTE radio frames shown in Figure 11, the #7 of first LTE radio frames, two sub-frame of uplink of #8 have disturbed the S1001Rx time slot of Bluetooth; And the #2 of the 3rd LTE radio frames, two sub-frame of uplink of #3 have disturbed the S1002Rx time slot of Bluetooth.Disturbance state design LTE sub-frame configuration bitmap according to Figure 11; The #7 of first radio frames shown in the figure; The #2 of #8 sub-frame of uplink and the 3rd radio frames, #3 sub-frame of uplink dispose to Bluetooth and carry out signal transmission, HARQ (the Hybrid Automatic RepeatRequest in order to satisfy the LTE system call simultaneously; Mix automatic repeat requests) sequential; Also dispose the descending sub frame with above-mentioned four the pairing HARQ of satisfying sequential of sub-frame of uplink to Bluetooth accordingly and carry out the signal transmission, remaining in addition all sub-frame configuration are carried out the signal transmission to LTE, and concrete LTE sub-frame configuration bitmap designs as follows:

0100100110 0100101001 0011001001

In the above sub-frame configuration bitmap, each representes a sub-frame, and one has 30 sub-frame, corresponding 3 LTE radio frames.Wherein the corresponding sub-frame configuration of " 1 " expression is used to Bluetooth, and the corresponding sub-frame configuration of " 0 " expression is used to LTE, can certainly carry out opposite expression.

Adopt above method; Can design and obtain under the various LTETDD uplink-downlink configuration; LTE sub-frame configuration bitmap under the different least interference time deviations; Thereby UE and eNB can arrange the least interference time deviation shown in (perhaps claiming the protocol specification standardization) form two and the LTE sub-frame configuration bitmap table of comparisons in view of the above, and wherein least interference time deviation index is optional agreement content.

Form two

According to the least interference time deviation shown in the form two and the LTE sub-frame configuration bitmap table of comparisons, according to the method flow diagram that the inventive method as shown in Figure 9 avoids interference, the concrete grammar that LTE and Bluetooth avoid interference is:

Step 1, LTE subset send to disturb to eNB avoids solicited message.

When the time deviation information of form two is decided to be LTE System Frame Number (System Frame Number approximately; SFN) be after the initial moment and this initial moment of 0 radio frames; And during the time difference between the zero-time of the Tescowindow of the Bluetooth that this initial moment time deviation is minimum; Then disturbing and avoiding solicited message is the time deviation information between LTE subset and the Bluetooth subset, perhaps LTE sub-frame configuration bitmap, wherein time deviation information specifically can for:

A), time deviation; Perhaps

Above-mentioned time deviation all is meant after the initial moment of the radio frames of LTE SFN#0, this initial moment and and this initial moment between time difference between the zero-time of a Tesco window of the minimum Bluetooth of time deviation.

When the Bluetooth subset in the terminal is main equipment; The Bluetooth subset can adjust and the LTE subset between time deviation (adjustment and LTE SFN#0 radio frames between time deviation); Make that time deviation between the two is the value in the least interference time deviation interval shown in the form two; Perhaps slave unit in the Bluetooth subset in the terminal; And the time deviation between Bluetooth subset and the LTE subset (and the time deviation between the LTE SFN#0 radio frames) just in time is the value in the least interference time deviation interval shown in the form two; Then the LTE subset reports above-mentioned time deviation information A), perhaps the LTE subset reports corresponding LTE sub-frame configuration bitmap after according to time deviation enquiry form two.

When the Bluetooth subset in the terminal is slave unit; Though perhaps the Bluetooth subset in the terminal is a main equipment; But the Bluetooth main equipment is not adjusted and the LTE subset between time deviation; Then the time deviation between Bluetooth subset and the LTE subset (and the time deviation between the LTE SFN#0 radio frames) might be in the least interference time deviation interval shown in the form two, and then the LTE subset reports above-mentioned time deviation information B).

When the time deviation information that relates in the form two is not stipulated the zero-time of concrete which LTE radio frames and after this radio frames zero-time; And between this radio frames zero-time during the zero-time of the Tesco window of the minimum Bluetooth of time deviation, disturb avoid solicited message be between LTE subset and the Bluetooth subset time deviation information and computing time employed LTE radio frames during deviation information SFN #X.Time deviation information specifically can be above-mentioned A) or B); The time deviation here is meant after initial moment of radio frames of LTE SFN#X, this initial moment and and this initial moment between time difference between the zero-time of a Tesco window of the minimum Bluetooth of time deviation.

Step 2, LTE subset receive the subframe configuration information that eNB sends to this LTE subset, dispose the sub-frame allocation information of keeping for the LTE subset and keeping for the Bluetooth subset in the subframe configuration information.

ENB receives after interference that the LTE subset sends avoids solicited message, according to the agreement of form two, disposes above-mentioned subframe configuration information.Concrete; Avoiding solicited message when the interference that receives is the time deviation information A between LTE subset and the Bluetooth subset) time; ENB further can be according to the service conditions of current LTE subset according to the agreement of form two, and subframe configuration information is confirmed in decision-making.As; The work at present of LTE subset is TDD uplink-downlink configuration 0 time; The time deviation information that the LTE subset reports is least interference time deviation index 1; Then the eNB enquiry form two, can confirm that subframe configuration information is a LTE sub-frame configuration bitmap " 1,001,100,000 1,000,010,011 0000010000 " in the form two.Perhaps further; After eNB is known LTE sub-frame configuration bitmap according to the Query Result of form two; The sub-frame configuration bitmap of considering form two is agreement under the full load condition spare at supposition LTE, and the non-full load of the traffic load of current UE, eNB can adjust on the basis of form two Query Results and confirm subframe configuration information; Reducing the number of sub frames of keeping for the Bluetooth subset, is " 0,000,000,000 1,000,010,011 0000010000 " such as adjusted subframe configuration information.In the above-mentioned subframe configuration information, " 1 " for keeping for the subframe of Bluetooth subset, " 0 " is for keeping for the subframe of LTE subset.Keep for the subframe of LTE subset need satisfy LTE HARQ sequential, and/or keep for the subframe of Bluetooth subset need satisfy LTE HARQ sequential.

Concrete; Avoiding solicited message when the interference that receives is the time deviation information B between LTE subset and the Bluetooth subset) time; ENB is according to the TDD uplink-downlink configuration of current LTE; With reference to each LTE sub-frame configuration bitmap that form two under this TDD uplink-downlink configuration is arranged, confirm subframe configuration information.Such as, considering that LTE subframe bitmap that form two is arranged is the sub-frame configuration that LTE and Bluetooth disturb hour, eNB increases the number of sub frames of keeping for the Bluetooth subset on the basis of certain LTE subframe bitmap that form two is arranged.Equally, in determined subframe configuration information, keep for the subframe of LTE subset need satisfy LTE HARQ sequential, and/or keep for the subframe of Bluetooth subset need satisfy the LTEHARQ sequential.

Concrete; When the interference that receives avoids solicited message to be LTE sub-frame configuration bitmap; ENB is according to the LTE sub-frame configuration bitmap that is reported; Further can be according to the service conditions of current LTE subset, subframe configuration information is confirmed in decision-making, concrete behavior be the time deviation information A between LTE subset and the Bluetooth subset with avoiding solicited message when the interference of reception) time behavior.

The above-mentioned subframe configuration information that eNB confirms decision-making sends to the LTE subset.Need to prove; The subframe configuration information of confirming when eNB decision-making and LTE subset are identical according to the table look-up LTE sub-frame configuration bitmap of gained of least interference time deviation or least interference time deviation index in S801; When the LTE sub-frame configuration bitmap that is perhaps reported with the LTE subset was identical, in this process, the subframe configuration information that eNB sends to the LTE subset can only be that notice LTE subset begins to disturb the indication information of avoiding; The subsequent implementation example is herewith explained, repeats no more.

Need to prove in addition; During subframe configuration information that the above-mentioned decision-making of eNB notice LTE subset is confirmed; If described subframe configuration information is enquiry form two determined subframe configuration informations, during practical implementation, UE and eNB are when agreement or title standardized tabular two; Can also encode to each the LTE sub-frame configuration bitmap under each TDD uplink-downlink configuration; Promptly set up the index information of each LTE sub-frame configuration bitmap, such as for three LTE sub-frame configuration bitmaps in the TDD uplink-downlink configuration 0 shown in the form two, can set up the index information shown in the form three:

Form three

LTE sub-frame configuration bitmap index	LTE sub-frame configuration bitmap
		0	1001100000 1000010011 0000010000
1	1000010011 0000010000 1001100000
		2	0000010000 1001100000 1000010011

Thereby the above-mentioned subframe configuration information of eNB notice UE can be the index information of LTE sub-frame configuration bitmap, and the subsequent implementation example is herewith explained, repeats no more.

If perhaps eNB receives after interference that the LTE subset sends avoids solicited message, judge that only there is speech business in current LTE subset; Or judge that the LTE subset promptly exists speech business to have other non-voice service again, but the eNB decision-making confirms only need guarantee the quality of service of speech business, and eNB has disposed up semi-persistent scheduling (the Semi-Persistent Scheduling of special transmitting voice service for the LTE subset; SPS) information and/or descending SPS information; ENB can not be LTE subset configuration LTE sub-frame configuration bitmap, and eNB sends to UE and characterizes the information of guaranteeing the speech business quality, and this sign guarantees that the information implication of speech business quality does; UE and eNB agreement; Up/descending SPS subframe according to up/descending SPS information calculations gained is to keep for the subframe of LTE subset, and other subframes are to keep for the subframe of Bluetooth subset, and subsequent implementation does not for example have specified otherwise; Herewith explanation is repeated no more.

Step 3, LTE subset carry out the signal transmission according to the subframe configuration information that step 2 received on the subframe of keeping for the LTE subset, keeping for stop signal transmission on the subframe of Bluetooth.

Concrete; Time deviation information in form two is decided to be LTE System Frame Number (System Frame Number approximately; SFN) be after the initial moment and this initial moment of 0 radio frames; And during the time difference between the zero-time of the Tesco window of the Bluetooth that this initial moment time deviation is minimum (summary is the time deviation of LTE SFN#0 radio frames and Bluetooth); Then the LTE subset is in the P that satisfies a SFN%P=0 radio frames, in corresponding subframe configuration information, keeps on the subframe of LTE subset and carries out the signal transmission, in corresponding subframe configuration information, keeps for stop signal transmission on the subframe of Bluetooth; P=L/10 wherein, L is that subframe configuration information is the length of LTE sub-frame configuration bitmap.Accordingly, eNB keeps in the corresponding subframe configuration information on the subframe of Bluetooth to stop the scheduling to the LTE subset in the P that satisfies a SFN%P=0 radio frames.

Such as in the present embodiment, when LTE sub-frame configuration bitmap that eNB disposed during for " 1,001,100,000 10000100110000010000 ", then the LTE subset is in per three radio frames that SFN%3=0 begins; Stop at and carry out the signal transmission on the subframe that is designated " 1 " in the LTE sub-frame configuration bitmap, in the present embodiment, first subframe of the radio frames of the corresponding SFN%3=0 of leftmost bit in " 1,001,100,000 10000100110000010000 "; Such as the #0 of LTE subset at SFN#0, #3, #4; The #0 of SFN#1, #5, #8; Stop signal transmission on the #5 subframe of #9 and SFN#2.

Concrete; When the time deviation information of form two is not stipulated the zero-time of concrete which LTE radio frames and after this radio frames zero-time; And between this radio frames zero-time during the zero-time of the Tesco window of the minimum Bluetooth of time deviation (summary is the time deviation of LTE SFN#X and Bluetooth); Then the LTE subset is in the P that satisfies a SFN%P=X radio frames; In corresponding subframe configuration information, keep for and carry out the signal transmission on the subframe of LTE subset; In corresponding subframe configuration information, keep for stop signal transmission on the subframe of Bluetooth, P=L/10 wherein, L is that subframe configuration information is the length of LTE sub-frame configuration bitmap.

Concrete; If the received subframe configuration information of LTE subset is guaranteed the information of speech business quality for sign; Then the LTE subset carries out the signal transmission on the up SPS subframe of eNB configuration and/or descending SPS subframe, and the LTE subset stops at except that the up SPS subframe of eNB configuration and/or the transmission of the signal on other subframes the descending SPS subframe.

Step 4, Bluetooth subset carry out the signal transmission according to the subframe configuration information that step 2 received on the subframe of keeping for the Bluetooth subset, stop signal transmission on the subframe of keeping for the LTE subset.

Concrete; When the time deviation information of form two is decided to be LTE System Frame Number (System Frame Number approximately; SFN) be after the initial moment and this initial moment of 0 radio frames; And during the time difference between the zero-time of the Tesco window of the Bluetooth that this initial moment time deviation is minimum, then the LTE subset is confirmed the subframe of in the P that satisfies a SFN%P=0 radio frames, keeping for LTE and/or keeping for Bluetooth according to subframe configuration information; P=L/10 wherein, L is that subframe configuration information is the length of LTE sub-frame configuration bitmap.The Bluetooth subset is perhaps kept for LTE through common controlling equipment S107 acquisition through the interface between each subset as shown in Figure 1 and/or is kept for the sub-frame information of Bluetooth; On the subframe of keeping for the Bluetooth subset, carry out the signal transmission, stop at the signal transmission on the LTE subframe of keeping for LTE.

Such as in the present embodiment, the Bluetooth subset is at the #1 of corresponding LTE SFN#0, #5, #6, #7, #8, #9, the #1 of SFN#1, #2, #3, #4, #6, the #0 of #7 and SFN#2, #1, #2, #3, #4, #6, #7, #8, stop signal transmission on the #9 subframe.

Concrete; When the time deviation information of form two is not stipulated the zero-time of concrete which LTE radio frames and after this radio frames zero-time; And between this radio frames zero-time during the zero-time of the Tesco window of the minimum Bluetooth of time deviation; Then the LTE subset is according to subframe configuration information; Confirm the subframe in the P that satisfies a SFN%P=X radio frames, keeping for LTE and/or keep for Bluetooth, P=L/10 wherein, L is that subframe configuration information is the length of LTE sub-frame configuration bitmap.The Bluetooth subset carries out the signal transmission on the subframe of keeping for the Bluetooth subset, stop at the signal transmission on the LTE subframe of keeping for LTE.

Concrete, if the received subframe configuration information of LTE subset is to characterize the information of guaranteeing the speech business quality, then the Bluetooth subset stops at the signal transmission on up SPS subframe and/or the descending SPS subframe.

Embodiment two

In view of the Bluetooth subset in the terminal equipment generally can exist as main equipment; Therefore on the basis of embodiment one; What UE and eNB arranged; Or claim that the standardized least interference time deviation of protocol specification and the LTE sub-frame configuration bitmap table of comparisons can also be optimized for the content shown in the form four, i.e. every kind of LTETDD uplink-downlink configuration a kind of least interference time deviation and pairing LTE sub-frame configuration bitmap in the standardized tabular two only.

Form four

According to the least interference time deviation shown in the form four and the LTE sub-frame configuration bitmap table of comparisons, according to method flow diagram shown in Figure 9, the concrete steps that present embodiment LTE and Bluetooth avoid interference are:

Step 1, LTE subset send to disturb to eNB avoids solicited message, and disturbing and avoiding solicited message is the indication of notice eNB configuration subframe configuration information.

Step 2, LTE subset receive the subframe configuration information that eNB sends to this LTE subset, dispose the sub-frame allocation information of keeping for the LTE subset and keeping for the Bluetooth subset in the subframe configuration information.ENB is according to current TDD uplink-downlink configuration; Enquiry form four is confirmed LTE sub-frame configuration bitmap; Further; ENB can combine the service conditions of current LTE subset simultaneously according to Query Result, and subframe configuration information is confirmed in decision-making, and the subframe configuration information of confirming decision-making sends to the LTE subset.

Step 3, LTE subset carry out the signal transmission according to the subframe configuration information that step 2 received on the subframe of keeping for the LTE subset, keeping for stop signal transmission on the subframe of Bluetooth.Concrete behavior is with the description of present embodiment one step 3.

Step 4, Bluetooth subset carry out the signal transmission according to the subframe configuration information that step 2 received on the subframe of keeping for the Bluetooth subset, keeping for stop signal transmission on the subframe of LTE.Concrete behavior is with the description of present embodiment one step 4.

Embodiment three

Least interference time deviation shown in the form two and the standardized LTE sub-frame configuration bitmap lengths of the LTE sub-frame configuration bitmap table of comparisons are that 30ms disturbs the repetition period among the embodiment one; In view of in the LTE sub-frame configuration bitmap; Keep for the subframe of LTE subset need satisfy LTE HARQ sequential; And/or the subframe of keeping for the Bluetooth subset need satisfy LTE HARQ sequential; LTE sub-frame configuration bitmap can be simplified; The i.e. configuration of reservations bitmap of sub-frame of uplink or descending sub frame in the standardization TDD uplink-downlink configuration only, LTE subset and eNB are derived according to the configuration of reservations bitmap of standardized sub-frame of uplink or descending sub frame and HARQ sequential and are confirmed complete LTE sub-frame configuration bitmap.Form five has provided the configuration of reservations bitmap of 30ms sub-frame of uplink in the interference repetition period on the basis of form two.

Form five

According to the least interference time deviation shown in the form five and the LTE sub-frame of uplink configuration bitmap table of comparisons, according to method flow diagram shown in Figure 9, the concrete steps that present embodiment LTE and Bluetooth avoid interference are:

Step 1, with embodiment one.

Step 2, LTE subset receive the sub-frame of uplink configuration information that eNB sends to this LTE subset, dispose the sub-frame of uplink assignment information of keeping for the LTE subset and keeping for the Bluetooth subset in the sub-frame of uplink configuration information.

This step implementation process need to prove that with embodiment one what present embodiment was inquired about is form five.

Step 3, LTE subset carry out the signal transmission according to the sub-frame of uplink configuration information that step 2 received on the subframe of keeping for the LTE subset, keeping for stop signal transmission on the subframe of Bluetooth.

The LTE subset is known the pairing descending sub frame assignment information of this sub-frame of uplink assignment information according to sub-frame of uplink configuration information and the derivation of HARQ sequential that S802 received; Thereby obtain the subframe configuration information in the 30ms cycle; According to the subframe configuration information of deriving; The LTE subset carries out the signal transmission on the subframe of keeping for the LTE subset, stop at the signal transmission on the subframe of keeping for Bluetooth.

Concrete; When the time deviation information of form two is decided to be LTE System Frame Number (System Frame Number approximately; SFN) be after the initial moment and this initial moment of 0 radio frames; And during the time difference between the zero-time of the Tesco window of the Bluetooth that this initial moment time deviation is minimum, then the LTE subset is kept in corresponding subframe configuration information and is carried out signal on the subframe of LTE and transmit in the P that satisfies a SFN%P=0 radio frames; In corresponding subframe configuration information, keep for stop signal transmission on the subframe of Bluetooth; P=L/N wherein, L are the length of form five sub-frame of uplink configuration bitmap, N for this sub-frame of uplink dispose bitmap the number of " U " subframe in the corresponding TDD uplink-downlink configuration.Accordingly, eNB keeps in the corresponding subframe configuration information on the subframe of Bluetooth to stop the scheduling to the LTE subset in the P that satisfies a SFN%P=0 radio frames.

In present embodiment; When sub-frame of uplink that eNB disposed configuration bitmap during for " 011,000 000,011 000000 "; UE is according to this sub-frame configuration bitmap and HARQ sequential relationship; The subframe configuration information " 10,011,000,001,000,010,011 0000010000 " in 30ms cycle is known in derivation, and then the LTE subset, stops at and carries out the signal transmission on the subframe that is designated " 1 " in the LTE sub-frame configuration bitmap in per three radio frames that SFN%3=0 begins at LTE subset then.

Concrete; When the time deviation information of form two is not stipulated the zero-time of concrete which LTE radio frames and after this radio frames zero-time; And between this radio frames zero-time during the zero-time of the Tesco window of the minimum Bluetooth of time deviation; Then the LTE subset is in the P that satisfies a SFN%P=X radio frames, keeps for stop signal transmission, wherein P=L/N on the subframe of Bluetooth in the corresponding subframe configuration information; L is the length of form five sub-frame of uplink configurations bitmap, N for this sub-frame of uplink dispose bitmap the number of " U " subframe in the corresponding TDD uplink-downlink configuration.

Step 4, Bluetooth subset are being kept for stop signal transmission on the subframe of LTE according to the sub-frame of uplink configuration information that step 2 received.

The LTE subset is known the pairing descending sub frame configuration information of this sub-frame of uplink configuration information according to sub-frame of uplink configuration information and the derivation of HARQ sequential that step 2 received; Thereby obtain the subframe configuration information in the 30ms cycle; According to subframe configuration information, stop at the signal transmission on the subframe of keeping for LTE.

The similar step 3 of the implementation of present embodiment repeats no more.

Embodiment four

Among embodiment one and the embodiment two; The LTE subset reports the sub-frame configuration bitmap of eNB; Being the LTE subset calculates the sub-frame configuration bitmap of gained according to the disturbed condition between LTE subset and the Bluetooth subset, or the sub-frame configuration bitmap that obtains according to enquiry form two or form four, in the sub-frame configuration bitmap; Keep for the subframe of LTE subset need satisfy the HARQ sequential, and/or keep for the subframe of Bluetooth subset need satisfy the HARQ sequential.In the present embodiment, the LTE subset reports the sub-frame configuration bitmap of eNB for writing down the LTE subset is disturbed the subframe position of Bluetooth subset by Bluetooth interference and/or LTE subset sub-frame configuration bitmap.After eNB receives that record LTE subset is disturbed by Bluetooth and/or the LTE subset disturbs the sub-frame configuration bitmap of subframe position of Bluetooth subset; According to the scheduling strategy of HARQ sequential and eNB, confirm the subframe configuration information of configuration to the LTE subset.Wherein the LTE subset record LTE subset that reports eNB is disturbed by Bluetooth and/or the LTE subset disturbs the sub-frame configuration bitmap of the subframe position of Bluetooth subset; Can be the LTE subset calculates gained according to the disturbed condition between LTE subset and the Bluetooth equipment, also can be that make an appointment with the eNB sub-frame configuration bitmap of (or claiming consensus standardization) of LTE subset inquiry UE contrasts the form gained.Form six is the Bluetooth sequential configuration hypothesis according to the embodiment of the invention, and least interference time deviation and record LTE subset are by a kind of table of comparisons between the sub-frame configuration bitmap (being called for short interfering subframe configuration bitmap) of the subframe position of Bluetooth interference and/or LTE subset interference Bluetooth subset under each the TDD uplink-downlink configuration that provides.

Form six

According to the table of comparisons shown in the form six, according to method flow diagram shown in Figure 9, the concrete steps that present embodiment LTE and Bluetooth avoid interference are:

Step 1, LTE subset are sent to disturb to eNB and are avoided solicited message, disturb avoid solicited message can for:

1) the time deviation information between LTE subset and the Bluetooth subset;

2) interfering subframe configuration bitmap;

3) indication of notice eNB configuration subframe configuration information;

Concrete, be 1 if solicited message is avoided in the interference that the LTE subset reports) or 2), its behavior is with embodiment one; If it is 3 that solicited message is avoided in the interference that the LTE subset reports), its behavior is with embodiment two.

Concrete; If it is 1 that solicited message is avoided in the interference that eNB receives) or 3); Then can know interfering subframe configuration bitmap behind the eNB enquiry form six; ENB further can be according to the service conditions and the HAQR sequential of LTE subset according to the interfering subframe configuration bitmap of inquiry gained, and decision-making confirms to dispose the subframe configuration information of giving the LTE subset.If it is 2 that solicited message is avoided in the interference that eNB receives) time, eNB further can be according to the service conditions and the HARQ sequential of current LTE subset according to the interfering subframe configuration bitmap that reports, and subframe configuration information is confirmed in decision-making.

In the subframe configuration information, keep for the subframe of LTE subset need satisfy LTE HARQ sequential, and/or keep for the subframe of Bluetooth subset need satisfy LTE HARQ sequential.

Embodiment five

In the present embodiment, UE and eNB do not arrange the least interference time deviation and the LTE sub-frame configuration bitmap table of comparisons, and according to method flow diagram shown in Figure 9, the concrete grammar that present embodiment LTE and Bluetooth avoid interference is:

Step 1, LTE subset send to disturb to eNB avoids solicited message.

Interference avoids solicited message to comprise:

Time deviation;

Bluetooth sequential configuration information: comprise that Bluetooth is the information of Master or Slave; The mode of operation information of Bluetooth (comprise that mode of operation is SCO, perhaps mode of operation is eSCO), Bluetooth is at the timeslot number of the next transmitting-receiving of mode of operation window.

ENB receives after interference that the LTE subset sends avoids solicited message; The TDD uplink-downlink configuration current according to LTE; The current scheduling strategy of eNB to this LTE subset; Avoid solicited message (being the time sequence information of Bluetooth) with the interference that the LTE subset reports, calculate the disturbance state of disturbing between interior LTE subset of repetition period and the Bluetooth subset.Concrete, eNB is in Tx slot if judgement scheduling LTE subset carries out the D/S time slot B luetooth of Data Receiving when calculating, and then this D/S time slot is disturbed; If carrying out the U time slot B luetooth of data transmission, scheduling LTE subset is in Rx slot, then this U time slot interference Bluetooth.

ENB is according to the scheduling strategy of disturbance state and current eNB; Configuration sends to the subframe configuration information of this LTE subset; Subframe configuration information can be the LTE sub-frame configuration bitmap of similar embodiment one, embodiment two, perhaps the LTE sub-frame of uplink of similar embodiment three configuration bitmap or LTE descending sub frame configuration bitmap.Keep for the subframe of LTE subset need satisfy LTE HARQ sequential, and/or keep for the subframe of Bluetooth subset need satisfy LTE HARQ sequential.The subframe configuration information that eNB confirms decision-making sends to the LTE subset.

If perhaps eNB receives after interference that the LTE subset sends avoids solicited message, judge that only there is speech business in current LTE subset; Or judge that the LTE subset promptly exists speech business to have other non-voice service again; But the eNB decision-making confirms only need guarantee the quality of service of speech business; And eNB has disposed the up SPS information and/or the descending SPS information of special transmitting voice service for the LTE subset; ENB is not LTE subset configuration LTE sub-frame configuration bitmap/LTE sub-frame of uplink configuration bitmap/LTE descending sub frame configuration bitmap; ENB sends to UE and characterizes the information of guaranteeing the speech business quality, and this sign guarantees that the information implication of speech business quality does, UE and eNB agreement; Up/descending SPS subframe according to up/descending SPS information calculations gained is to keep for the subframe of LTE subset, and other subframes are to keep for the subframe of Bluetooth subset.

Step 3, LTE subset carry out the signal transmission according to the subframe configuration information that step 2 received on the subframe of keeping for the LTE subset, stop signal transmission on the subframe of keeping for the Bluetooth subset.

Concrete, if the received subframe configuration information of LTE subset is a LTE sub-frame configuration bitmap, then concrete implementation is with embodiment one step 3; If the received subframe configuration information of LTE subset is LTE sub-frame of uplink configuration bitmap or LTE descending sub frame configuration bitmap, then concrete implementation is with embodiment three; If the received subframe configuration information of LTE subset is to characterize the information of guaranteeing the speech business quality, then the LTE subset stops at up SPS subframe and/or the transmission of the signal on other subframes the descending SPS subframe except that the eNB configuration.

Concrete, if the received subframe configuration information of LTE subset is a LTE sub-frame configuration bitmap, then concrete implementation is with embodiment one step 3; If the received subframe configuration information of LTE subset is LTE sub-frame of uplink configuration bitmap or LTE descending sub frame configuration bitmap, then concrete implementation is with embodiment three; If the received subframe configuration information of LTE subset is to characterize the information of guaranteeing the speech business quality, then the Bluetooth subset stops at the signal transmission on up SPS subframe and/or the descending SPS subframe.

Need to prove that in the embodiment of the invention, all LTE sub-frame configuration bitmap lengths are 30ms for example; In the practical application, according to different demands, LTE sub-frame configuration bitmap lengths does not limit 30ms; Such as if consider the complete HARQ sequential repetition period under the different TDD uplink-downlink configuration situation; TDD uplink-downlink configuration 1 time, the complete HARQ sequential repetition period is 20ms, LTE sub-frame configuration bitmap lengths can be 60ms.

Method through various embodiments of the present invention; When on the LTE subset is being kept for the subframe of LTE subset, carrying out the signal transmission; The transmission of Bluetooth subset stop signal, vice versa, can effectively avoid the interference between LTE subset and the Bluetooth subset.

First subset 1201 also is used on the subframe of keeping for first subset 1201, carrying out the signal transmission;

Second subset 1202 is used on the subframe of keeping for second subset 1202, carrying out the signal transmission.

In one embodiment; First subset 1201 can also be used for when the subframe configuration information is the sub-frame configuration bitmap index of sub-frame of uplink and descending sub frame configuration bitmap or correspondence; According to the time deviation of opposite equip. agreement; On the subframe of keeping for first subset, carry out the signal transmission, stop signal transmission on the subframe of keeping for second subset; Wherein, time deviation refers to the time difference between the zero-time of a radio frames of zero-time and second subset of a radio frames of first subset.
