Fig. 2 has explained orally the example of the wireless communication system 290 of supporting a plurality of subscriber equipmenies.In Fig. 2, reference number 292A refers to cellular cell to 292G, and reference number 298A refers to base station (BS) or is the B node to 298G, and reference number 296A refers to 296J and inserts subscriber's installation (also being called subscriber's installation (UE)).The cellular cell scale can have nothing in common with each other.Any algorithm and method in various algorithms and the method can be used to the transmission in the dispatching system 290.System 290 provides communication for several cellular cells 292A to 292G, and each in these cellular cells is served to 298G by relevant base station 298A respectively.
A key property of communication network is for transmission of electric signals between these network nodes wired or wireless medium to be selected.In the situation of cable network, adopt and on certain distance, propagate the guidance electromagnetic waveforms of carrying the message traffic such as the tangible physical medium of copper cash, concentric cable, fiber optic cables etc.Cable network is the traditional form of communication network and for the interconnected of fixed network element or for batch data shifts, possibly be dominant.For example, fiber optic cables often are preferred transmission mediums for continent or the batch data transmission between the continent etc. are used, for example striden at the earth's surface in the very high-throughput transmission on the long distance between the catenet hub.
On the other hand, in many situations, if when network element be move and when having dynamic connectivity or the network architecture be that wireless network is preferred under the situation about forming with self-organization (ad hoc) rather than fixing topology.Wireless network uses the electromagnetic wave in the frequency bands such as radio frequency, microwave, infrared, optical frequency to adopt invisible physical medium with non-guidance communication mode.Wireless network be fixed with spider lines and compare the unique promotion user mobility and the quick advantage of field deployment.Yet, mutual coordination and the cooperation using radio transmission need between the network user, carry out significant initiatively resource management and compatible spectrum utilization carried out high level.
For example, popular radio network technique comprises bluetooth (BT) and wireless lan (wlan).As the wired interconnected replacement between the local component, bluetooth is a kind of realization very short distance that is widely used, the wireless communication protocol of the individual territory net (PAN) on the coverage of several meters radiuses normally.In one example, bluetooth can be used to connect personal computer, PDA(Personal Digital Assistant), mobile phone, wireless headset etc.Alternatively, adopt such as WiFi or the more generally procotol of IEEE 802.11 wireless protocols families etc. and the connection between phone and the laptop computer, WLAN can be used to devices interconnect nearby together for commercial and consumer applications is used.
It is that the user shares identical radio frequency band through the identical geographic area of being everlasting and transmits that of radio network technique considers.Therefore, common-channel interference is must be by the problem of active management.For example, bluetooth all can be used near no license industry, science and medical treatment (ISM) radio bands of the identical center 2.4GHz frequency with wlan system.In one example, in order to practice thrift cost, mobile device can be shared the common antenna that inserts these two kinds of wireless technologys.In order to support to carry out simultaneously user's scene of BT and WLAN operation, just require to have the coexistence algorithm.Therefore, need the coexistence algorithm to come to be the wireless device arbitration bluetooth of coexistence and the use between the WLAN access technology.
In order between the wireless protocols of coexistence, to mediate, in one example, coexistence mechanism is used.Coexistence mechanism can be a collaboration type perhaps, and wherein information is shared between communication parties, perhaps can be non-collaboration type, and wherein information is not shared.The coexistence mechanism of a collaboration type is called as packet traffic arbitration (PTA).PTA uses medium Access Control (MAC) layer to carry out traffic control usually.
In current wireless practice, packet traffic arbitration (PTA) agreement is used to realize the coexistence between different access technologies.In one example, PTA can realize through 2,3 or 4 wireline interfaces between BT in the wireless device and the WLAN electronic chip.Every kind of access technology is made channel request to individual packets, and this request is had optional priority indication.In one example, the moderator between BT access technology and the WLAN technology is operated in medium Access Control (MAC) layer.
PTA makes decision to being obtained to insert by whom when the contention channel request simultaneously of two kinds of access technologies.This mechanism can prevent between these technology for some conflict of emission traffic but not prevent to receive the conflict between the traffic.Conflict is the conflict when two or more data sources attempted on same media, to transmit in the identical time.
For example, PTA is implemented as hardware interface and the arbitration agreement between inherent WLAN module of subscriber equipment and the bluetooth module usually.In one example, WLAN module and bluetooth module comprise integrated circuit (IC).PTA generally includes at least three signals:
BT_ACTIVE-is asserted to reach to transmit and lasts
BT_STATUS-indication priority and transmission direction
Can the TX_CONFIRM-indication be transmitted in next time slot and proceeded
FREQ (can choose wantonly)-indication frequency state
PTA supposes that generally WLAN module (for example, WLAN IC) is the arbitrator.Although PTA is feasible coexistence agreement, it still has some limitations.For example, PTA requires three signals, and it is not extendible easily, and it is not contained such as other wireless standards such as LTE or WiMax.PTA is point-to-point agreement, and it can not be upgraded with the communication between two above subscriber equipmenies in the back-up system.
The disclosure comprises the improvement to the PTA agreement.Be called enhancement mode PTA (ePTA) through improved agreement.For higher user satisfaction is provided, ePTA there are some requirements.In one aspect, outer I/O (I/O) interface of MIN (being preferably one) sheet is preferable.For example, the Parallel Digital interface of ePTA can be used to the BT-WLAN integration on the sheet.On the other hand, bigger information transmission is desirable.For example, more bits should be assigned to radio activity, priority level, emission/accepting state, frame synchronization and frame and utilize state etc.This does not comprise that RF shares control bit (for example, LNA gain, power amplifier setting, TX/RX switching controls), because electrification reset (PoR) control is safeguarded by the BT/WLAN module.On the other hand, for request or signal priority and Yan Shiji should be low latency (for example, below 10 microseconds) and have the response time flexibly.In one aspect, the alternative existing P TA agreement of ePTA and do not have functional loss or base requirement when stricter.Other desirable attributes comprise (multi-drop) ability of drawing (for example, BT, WLAN and LTE/WiMax) more, when one or more subscriber equipment dormancy functional, avoid with equipment from dormancy, wake up and electricity consumption low.
Fig. 3 has explained orally the example of ePTA system.What illustrate is three example apparatus, has its oneself reference clock separately.In one aspect, reference clock is used to the communication of these equipment rooms synchronously.These three equipment are interconnected through the ePTA bus, this ePTA bus be single line share draw data bus more.The ePTA bus is always drawn high by all devices, but is driven low to transmit.Reference clock need enliven for the equipment that communicates actively.In one aspect, reference clock need not be balanced or frequency is identical, because the ePTA bus is by over-sampling.In one example, do not use S.C. serial bus interface (SSBI), because it is point-to-point synchronous protocol.
Fig. 4 has explained orally the example of the physical interface that is used for the ePTA system.In one example, select to have the good auto-correlation and the scrambled code of their cross correlation.In one aspect, scrambled code is used to device identification, initial synchronisation, data albefaction and collision detection.In one example, transmission starts from sync byte (with hexadecimal format 0xFF scrambling) and stops byte (without the hexadecimal format 0xFF of scrambling) finally.Can obtain conflict via the priority facility of being assigned (for example, back off time) avoids.When two equipment are on same tube core, then replace and use directly (for example, inside) connection.
Fig. 5 has explained orally the example of the signal time line of two subscriber equipmenies.In one example, first equipment is gone ahead of the rest after initial synchronisation, and second equipment is accepted synchronization character on time.
Fig. 6 has explained orally the example of the signal time line of three subscriber equipmenies.In this example, all devices is attempted to communicate by letter and all devices all fails to accept the synchronization character of other equipment first in the identical time after synchronously.
In one aspect, the agreement that is used for exchanges data depends on the access technology that each equipment is using.In one example; For bluetooth (BT), whether binary signal indication BT is active, 3 bit signals indication BT priority state; Another binary signal indication emission/accepting state, and another status signal is indicated various other state variables such as frequency etc.In another example, (for example, WiFi), status signal is indicated the permission state of interface for WLAN.In another example; For LTE/WiMax; " frame synchronization (Frame_sync) " signal can be used for synchronously by other access technologies; It is just to be used or can to supply BT or WLAN to use that " frame uses (Frame_Used) " signal can be used to indicate current LTE/WiMax frame, and whether the permission signal can be used to indicate access to be granted.In one example, bluetooth equipment requires have good time base to control so that realize good effectiveness to " frame synchronization " signal termination.This can be through making when low this bluetooth equipment catch " frame synchronization " if clock, " frame synchronization " bit is set then interrupt software is reached subsequently in initial request.
Fig. 7 has explained orally use ePTA agreement and has been used as being used for the example that substitutes that packet traffic is arbitrated the PTA agreement of (PTA).In one aspect, existing PTA signaling is replaced by 5 ePTA clearing houses.Be BT time slot time base shown in Fig. 7, BT_ACTIVE (BT is active) signal, BT_STATUS (BT state) signal, FREQ state (frequency state) signal and TX_CONFIRM (TX affirmation) signal.
Fig. 8 has explained orally the example flow diagram of enhancement mode packet traffic arbitration.In frame 810, excited users equipment.In one example, subscriber equipment is a bluetooth equipment.In one example, through asserting that the BT_ACTIVE signal is high this subscriber equipment that activates.Follow after frame 810, in frame 820, pass on priority state.In one example, this priority state is the priority state of subscriber equipment.In one example, this priority state is conveyed to second subscriber equipment, base station, network controller, explorer etc.The tabulation that it will be understood by those skilled in the art that the take over party of this priority state is not to be comprehensive or exclusive, and can comprise other take over partys and do not influence the scope of the present disclosure or spirit.
