Specific embodiment

It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood The application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, not For limiting the application.

Referenced herein " embodiment " is it is meant that a particular feature, structure, or characteristic described can wrap in conjunction with the embodiments It is contained at least one embodiment of the application.Each position in the description occur the phrase might not each mean it is identical Embodiment, nor the independent or alternative embodiment with other embodiments mutual exclusion.Those skilled in the art explicitly and Implicitly understand, embodiment described herein can be combined with other embodiments.

The signal transmit-receive method of WLAN provided by the present application and Bluetooth coexistence can be applied to application ring as shown in Figure 1 In border.Wherein, which includes the wireless access points of terminal device and WLAN, wherein the number of terminal device Amount can be two, respectively first terminal equipment and second terminal equipment, and first terminal equipment has SOC system, the SOC system It is integrated with bluetooth (BT) and WLAN (WLAN)；Bluetooth in the SOC system of second terminal equipment and first terminal equipment Module can establish communication connection, and the WLAN module in wireless access points and the SOC system can establish communication connection.Wherein, Wireless access points are but are not limited to wireless router, and two terminal devices can be PC, smart phone, plate electricity Brain, vehicle-mounted computer, personal digital assistant, portable wearable device etc..

It should be noted that the application, which is directed to WLAN and bluetooth, uses this feelings of identical wireless simulation RF circuit Condition, such as the two can be integrated in the same SOC system, and the solution is to bluetooths in this case and WLAN how to coexist by the application The problem of, the signal transmit-receive method of the WLAN and Bluetooth coexistence that provide also are based on this.Just because of being directed to WLAN and indigo plant Tooth is integrated into same SOC chip, thus determines that the operating condition of WLAN and bluetooth is limited；Generally for save at This, the two needs to be multiplexed the same simulation RF circuit, it is contemplated that avoids the two from interfering with each other, usually makes indigo plant using PTA moderator Tooth and WLAN time-sharing work, but WLAN and the communication efficiency of bluetooth are lower.The application precisely in order to balance cost, mutual interference with And the interactional factor such as WLAN and the communication efficiency of bluetooth, propose the signal transmitting and receiving side of a kind of WLAN and Bluetooth coexistence Method.

In one embodiment, as shown in Fig. 2, the signal transmit-receive method of a kind of WLAN and Bluetooth coexistence are provided, with this Method is applied to be illustrated for the SOC system of the first terminal equipment in Fig. 1, comprising the following steps:

S202 detects that bluetooth sends signal.

Wherein, bluetooth sends signal and refers to Bluetooth signal to be sent, and similarly, WLAN mentioned below sends signal Refer to WLAN signal to be sent, Bluetooth received signals refer to that Bluetooth signal to be received, WLAN receive signal and refer to WLAN signal to be received.

S204 obtains WLAN working frequency range bandwidth；Bluetooth and WLAN are multiplexed a wireless receiving and dispatching channel.

WLAN working frequency range bandwidth refers to the band bandwidth occupied and its range specifically covered when WLAN communication, really Determine this feature and is conducive to subsequent bluetooth frequency hopping operation.

In addition, wireless receiving and dispatching channel is referred to transmission-receiving function, such as it can individually send wireless transmission bluetooth and send Signal, individually send wireless transmission WLAN send signal, individually receive Bluetooth received signals, individually receive WLAN receive signal, Bluetooth is sent simultaneously to send signal and WLAN transmission signal while receiving Bluetooth received signals and WLAN reception signal while sending out It send bluetooth to send signal and receive WLAN reception signal and receive Bluetooth received signals simultaneously and send WLAN and sends signal Data link.

It should be noted that it is to define that the technical solution of the application is that bluetooth and WLAN, which are multiplexed a wireless receiving and dispatching channel, Identical wireless simulation RF circuit is used based on WLAN and bluetooth, the two can be integrated in the same SOC system in practical operation On system.

S206 sends signal to bluetooth and carries out frequency hopping, makes in its frequency hopping to the coverage area of WLAN working frequency range bandwidth.

In view of being broadband signal due to WLAN, bluetooth is narrow band signal, and the bandwidth as WLAN communication occupies is 20MHZ/ 40MHZ, and Bluetooth communication has only taken up 1MHZ bandwidth, then can then cover 20/40 frequency of bluetooth in the bandwidth of WLAN Road, when bluetooth realizes frequency hopping communications in 20/40 channel, then the communication channel of bluetooth is can all to be covered by WLAN 's.It is that the signal energy of bluetooth only concentrates in 1MHZ bandwidth when bluetooth and WLAN signal exist simultaneously, and the signal energy of WLAN Amount is then dispersed in 20MHZ/40MHZ bandwidth, and the very big chance of the signal-to-noise ratio of bluetooth still can satisfy requirement at this time；And WLAN It is spread spectrum communication, when signal only has the frequency of part to be interfered, signal-to-noise ratio is also to have very big chance to can satisfy requirement 's.

Based on this, in some embodiments, signal is sent to bluetooth and carries out frequency hopping, makes its frequency hopping to WLAN working frequency range band It can be achieved on transmission and bluetooth while bluetooth sends signal and WLAN transmission signal in wide coverage area and send signal Individually sending for signal is sent with WLAN.Detection, transmission of traditional bluetooth and WLAN in wireless receiving and dispatching channel need to rely on PTA moderator, timesharing transmission easily cause loss of data, have seriously affected data throughput and communication efficiency；And in the present embodiment In, the state of bluetooth and WLAN while processing detection and transmission can be made, effectively increase communication efficiency.

S208, the bluetooth after frequency hopping is sent by the first passage mode in wireless receiving and dispatching channel send signal；First passage Mode is the mode for allowing bluetooth and WLAN to send simultaneously.

Based on step S202-S206, can construct to obtain the first passage mould in wireless receiving and dispatching channel in some embodiments Formula sends while to realize bluetooth and WLAN or individually sends.In the present embodiment, the of the wireless receiving and dispatching channel One channel pattern sends signal for individually sending bluetooth；The mode of the first passage mode in specific building wireless receiving and dispatching channel can To be a variety of, as long as can satisfy following several points requirements.

First under the premise of meeting WLAN frequency fixing communication, bluetooth is sent into signal and carries out frequency hopping, makes its frequency hopping to WLAN In the coverage area of working frequency range bandwidth；In addition, every interference when in order to reduce and avoid bluetooth and WLAN while sending, needs In a certain range by the energy ratio control of the two, the specific energy ratio can be configured according to the actual situation.

The feasibility analysis of scheme is as follows: according to bluetooth and the spectral characteristic of WLAN it is found that the energy due to bluetooth is concentrated, WLAN power dissipation, then WLAN is smaller to the interference of bluetooth, bluetooth can keep enough signal-to-noise ratio to realize normal send；And Since WLAN has used spread spectrum Anti-Jamming Technique, only fraction frequency spectrum is interfered, is not interfered largely, because This, overall, the interference that WLAN is subject to be also it is lesser, do not influence normally to send.Certainly, also need bluetooth and Than system under a certain range, bluetooth can be solved and the problem of WLAN is sent jointly in the energy control of WLAN in this way.

It should be pointed out that unless what bluetooth and WLAN were needed while being sent there are particularly important signal, or both Semaphore is very intensive, when belonging to big data transmission, just needs arbitral agreement coordinating bluetooth and WLAN to carry out timesharing use, generally When signal and data transmission are not very intensive, preferable communication efficiency can reach using the method sent simultaneously.

In the above embodiment of the present invention, executing subject can be the SOC system of first terminal equipment in Fig. 1, specific above-mentioned each The executing subject of a step can be at least one comprising modules in SOC system, can specifically carry out according to the actual situation selection and Change.

In the WLAN of above-described embodiment and the signal transmit-receive method of Bluetooth coexistence, one is multiplexed wirelessly based on bluetooth and WLAN Transceiver channel by after detecting that bluetooth sends signal, obtaining WLAN working frequency range bandwidth, and sends signal to bluetooth and carries out Frequency hopping makes in its frequency hopping to the coverage area of WLAN working frequency range bandwidth, so by the permission bluetooth in wireless receiving and dispatching channel and The mode that WLAN is sent simultaneously sends the bluetooth transmission signal after frequency hopping, so that the bluetooth after frequency hopping sends signal without waiting for i.e. It can send at any time, effectively increase data throughput and communication efficiency.

In some embodiments, Fig. 3 is referred to, the signal transmit-receive method of the WLAN and Bluetooth coexistence further include:

S203, if also detecting that WLAN sends signal while detecting that bluetooth sends signal；

S207, the bluetooth after frequency hopping is sent by the first passage mode in wireless receiving and dispatching channel sends signal and WLAN is sent The mixed signal of signal.

In the present embodiment, the first passage mode in the wireless receiving and dispatching channel is used to while sending bluetooth send signal and WLAN Send signal；The time that signal and WLAN transmission signal are sent simultaneously is sent in order to save bluetooth, improves transmitting efficiency simultaneously, this Bluetooth is sent after signal is mixed with WLAN transmission signal and is sent by place, and specific mixed media, the hardware of use or software are equal It can be chosen according to the actual situation.

In a specific embodiment, the indigo plant after frequency hopping is sent above by the first passage mode in wireless receiving and dispatching channel The step of tooth transmission signal and WLAN send the mixed signal of signal specifically includes: the bluetooth after frequency hopping is sent signal and WLAN It sends signal to be overlapped by setting power proportions, obtains mixed signal；It is sent out by the first passage mode in wireless receiving and dispatching channel Send mixed signal.

Wherein, signal and WLAN transmission signal progress power control, power distribution are sent to the bluetooth after frequency hopping and folded Add operation can realize that the specific power proportions that set can guarantee that WLAN and bluetooth are with higher by Signal averaging module On the basis of communication efficiency, set according to the actual situation.

It accordingly, is that can satisfy the two together in the case that the power distribution of the WLAN in mixed signal and bluetooth is proper When the condition that sends.Specifically, the setting power proportions can according to the bluetooth after frequency hopping send signal communication speed and/or Communication reliability and WLAN send the communication speed of signal and/or communication reliability determines.

In some embodiments, above-mentioned steps S206 is specifically included: obtaining the first digital mixing signal, the first digital mixing Signal is determined according to WLAN working frequency range bandwidth；Bluetooth is sent signal to be mixed with the first digital mixing signal, with this reality Signal now is sent to bluetooth and carries out frequency hopping, is made in its frequency hopping to the coverage area of WLAN working frequency range bandwidth.

In the present embodiment, in order to meet WLAN frequency fixing communication (at this point, the centre frequency of RF is fixed) and bluetooth frequency hopping The requirement of communication, bluetooth can realize the coverage area of frequency hopping to WLAN working frequency range bandwidth by a digital mixing module Effect.The digital mixing module can determine the first digital mixing signal according to WLAN working frequency range bandwidth；Specifically, first number Word mixed frequency signal can determine that known bluetooth herein is jumped by bluetooth digital processing module according to known Bluetooth Frequency Hopping Sequence Frequency sequence is obtained by the negotiations such as bluetooth standard protocol and WLAN working frequency range bandwidth.

Based on this, digital mixing module is can be used in the frequency hopping of bluetooth rather than the phaselocked loop of analog circuit is assisted realizing, Persistently switch to reduce phase lock loop locks frequency.This method compared with general PTA arbitration or other arbitration negotiation mechanisms, It is easy to control and convenient for practice, bluetooth and the efficient communication bandwidth of WLAN is improved greatly.

In some embodiments, above-mentioned the step of being mixed bluetooth transmission signal with the first digital mixing signal, packet It includes: the locking frequency of analog phase-locked look is set according to WLAN working frequency range bandwidth；Keep the locking frequency of analog phase-locked look constant, Bluetooth signal is sent by analog phase-locked look to be mixed with the first digital mixing signal.

I.e. when realizing the frequency hopping operation of bluetooth, the locking frequency of analog phase-locked look can be set according to WLAN channel And remain unchanged, it is mixed by the way that bluetooth is sent signal with the first digital mixing signal to achieve the purpose that bluetooth frequency hopping； This method is easily controllable, and practice is easy, and improves the communication efficiency and efficient communication bandwidth of bluetooth and WLAN.

In some embodiments, the signal transmit-receive method of the WLAN and Bluetooth coexistence further include: WLAN works if detecting Band bandwidth changes, it is determined that the first new digital mixing signal；By the first new digital mixing signal, bluetooth is sent out In the coverage area of WLAN working frequency range bandwidth of the number of the delivering letters frequency hopping to after changing.

In this way, the WLAN and the signal transmit-receive method of Bluetooth coexistence can be carried out according to the service condition of first terminal equipment The adaptive frequency hopping of bluetooth and the adjustment of working frequency range；It is rear to open this specifically for example, if first setting the WLAN function of this equipment Equipment bluetooth, then bluetooth needs the Bluetooth communication connecting according to its adaptive frequency hopping rule with this equipment, and bluetooth is made to send letter Number in frequency hopping to the coverage area of WLAN working frequency range bandwidth；Similarly, rear to open this if first setting this equipment Bluetooth function Equipment WLAN, bluetooth is also required to the adaptive frequency hopping rule using bluetooth in time, so that the bluetooth that this equipment is sent sends signal In equal frequency hopping to WLAN working frequency range bandwidth coverage；And when the coverage area of WLAN working frequency range bandwidth changes, The hopping position of bluetooth also should be followed in time, changes and be adjusted.The method achieve the adaptivitys of bluetooth frequency hopping rule, mention The feasibility and practicability of high above-mentioned WLAN and the signal transmit-receive method of Bluetooth coexistence, utilization rate are high.

In some embodiments, the signal transmit-receive method of the WLAN and Bluetooth coexistence further include: if detecting bluetooth hair While the number of delivering letters, also detect that WLAN receives signal；Start preset arbitration mechanism；Arbitration mechanism is for leading to wireless receiving and dispatching The current channel pattern switching in road is second channel mode or third channel mode；Second channel mode is that bluetooth is allowed to receive and dispatch The mode for forbidding WLAN to receive and dispatch, third channel mode are that WLAN is allowed to receive and dispatch the mode for forbidding bluetooth to receive and dispatch；If arbitration mechanism Arbitration result is second channel mode, sends bluetooth by the second channel mode in wireless receiving and dispatching channel and sends signal；If arbitration The arbitration result of mechanism is third channel mode, receives WLAN by the third channel mode in wireless receiving and dispatching channel and receives signal.

In further embodiments, the signal transmit-receive method of the WLAN and Bluetooth coexistence further include: if being detected simultaneously by indigo plant Tooth receives signal and WLAN sends signal, starts preset arbitration mechanism；If the arbitration result of arbitration mechanism is second channel mould Formula receives Bluetooth received signals by the second channel mode in wireless receiving and dispatching channel；If the arbitration result of arbitration mechanism is third Channel pattern sends WLAN by the third channel mode in wireless receiving and dispatching channel and sends signal.

In the above two embodiments, above-mentioned wireless receiving and dispatching channel passes through second channel mode, third channel mode, with Realize that bluetooth is individually received and dispatched and WLAN is individually received and dispatched；Second channel mode, third channel mode compare first passage mode, need Start preset arbitration mechanism, when which can be used existing arbitration mechanism to realize WLAN and Bluetooth coexistence The situation that one hair one is received.

In some embodiments, the signal transmit-receive method of the WLAN and Bluetooth coexistence further include: be in wireless receiving and dispatching channel In the state of fourth lane mode, if being detected simultaneously by Bluetooth received signals and WLAN reception signal, Bluetooth received signals are extremely Bluetooth signal in the coverage area of WLAN working frequency range bandwidth；Bluetooth is received by the fourth lane mode in wireless receiving and dispatching channel It receives signal and WLAN receives signal；Fourth lane mode is to allow bluetooth and WLAN received mode simultaneously.

In further embodiments, the signal transmit-receive method of the WLAN and Bluetooth coexistence further include: in wireless receiving and dispatching channel In the state of above-mentioned fourth lane mode, if detecting Bluetooth received signals, but WLAN is not detected and receives signal；Then lead to The fourth lane mode for crossing wireless receiving and dispatching channel receives Bluetooth received signals.

The signal transmit-receive method of the WLAN and Bluetooth coexistence in yet other embodiments, further include: in wireless receiving and dispatching channel In the state of above-mentioned fourth lane mode, if detecting, WLAN receives signal, but Bluetooth signal is not detected；Then pass through nothing The fourth lane mode of line transceiver channel receives WLAN and receives signal.

In the present embodiment, above-mentioned wireless receiving and dispatching channel receives while realizing bluetooth and WLAN by fourth lane mode. Wherein, Bluetooth received signals are the signal in the coverage area of WLAN working frequency range bandwidth, so that Bluetooth received signals frequency conversion Into the input requirements of bluetooth digital processing module, bluetooth digital processing module can be facilitated to handle；Specific concept feasible Property is analyzed as follows:

Firstly, since the energy proportion of aerial bluetooth and WLAN be it is unknown, when skyborne bluetooth and WLAN occur In the case where being unknown, time-sharing method needs continuous timesharing switching to attempt to receive bluetooth and WLAN, in this way it is possible to be switched to WLAN is reached when bluetooth receives, and is switched to bluetooth when WLAN is received and is reached, it is therefore more likely that occur that data packet do not receive asks Topic.This programme is not in bluetooth and WLAN signal to be received by allowing while receiving bluetooth and WLAN signal to be received Simultaneously when reaching, all data packets can be received, and when bluetooth and WLAN communication data are not very big, the two is different When to reach be Great possibility, be based on above content, can embody this programme allows while receiving bluetooth and WLAN is had Superiority, this method effectively improves the data throughput and communication efficiency of bluetooth and WLAN in signal receive process.

In addition, when bluetooth and WLAN arrive simultaneously, no matter using receiving simultaneously or timesharing reception, signal all can be by Interference, i.e., no matter which kind of receives mode, and signal is interfered and is all inevitable.Specifically for example, no matter using which kind of reception It will appear obstruction interference when mode, bluetooth and WLAN signal coexist, i.e., big signal will cover small signal to hinder small signal It receives；If when so that the energy of bluetooth and WLAN being carried out while being received under certain ratio, the two is can but according to this method With what is normally demodulated；Only when bluetooth and more greatly different WLAN energy distribution, although the very big signal of energy can be normal Demodulation, but the very small signal of energy malfunctions heavily disturbed and then reception, and this method can be by optimizing and monitoring this Energy allocation proportion, to minimize bluetooth and obstruction interference that when WLAN signal coexists occurs.It is transmitted in signal and data When being not very intensive, preferable communication efficiency can achieve with method of reseptance simultaneously.

To sum up, second channel mode, third channel mode are compared unlike first passage mode, fourth lane mode, Need to start preset arbitration mechanism, which can be used existing arbitration mechanism to be suitable for WLAN and bluetooth The situation that a hair one is received when coexisting.

It should be noted that WLAN and bluetooth can be realized simultaneously or be divided by the fourth lane mode in wireless receiving and dispatching channel It does not receive or detect individually, individually hair can also be realized simultaneously or separately by the first passage mode in wireless receiving and dispatching channel It send.Only when needing bluetooth and WLAN mono- receives another transmission, just need which is negotiated using default arbitration mechanism It first comes into force or comes into force at once, which, which cannot come into force or be delayed, comes into force, and other states can use arbitration mechanism as needed.This Sample then simplifies traditional PTA arbitration mechanism, but also bluetooth and WLAN have more efficient communication times.

In conjunction with above content it is found that the above embodiments of the present application propose WLAN and Bluetooth coexistence signal transmit-receive method, Using the rule for capableing of adaptive frequency hopping with roomy and bluetooth of WLAN communication, so that the frequency point of its frequency hopping is fallen when Bluetooth communication In the coverage area for entering WLAN working frequency range bandwidth, while Frequency mixing processing is carried out before and after Bluetooth modulation demodulation.In this way, mould The frequency of quasi- phaselocked loop may be locked in the coverage area center of WLAN working frequency range bandwidth, without because of bluetooth frequency hopping and WLAN and indigo plant Tooth frequency point is different and ceaselessly switches.Simultaneously can make WLAN and bluetooth and meanwhile receive energy be suitble to signal (Bluetooth signal is narrow Band signal, energy comparison are concentrated, and WLAN signal is broadband signal, blue under maximum probability situation when the two signal occurs simultaneously Tooth and WLAN may be implemented normally to demodulate)；In addition, only needing the energy of reasonable distribution bluetooth and WLAN signal and being superimposed the two Transmission while signal can be thus achieved in mixing, without complicated control scheduling strategy, so that it may improve WLAN and Bluetooth coexistence When signal transmitting and receiving problem, ideal effect can be easily reached in conjunction with the PTA resolving strategy of protocol layer.

What above-described embodiment scheme had has the beneficial effect that:

1, WLAN and bluetooth equipment can be received simultaneously and be sent simultaneously, and bluetooth and WLAN obtain more efficient communications Time effectively increases data throughput and communication efficiency；
