Description

A kind of channel detection method of unauthorized frequency range and network element device

Technical field

The present invention relates to communication technical field, be specifically related to a kind of channel detection method and network element device of unauthorized frequency range.

Background technology

Along with the sharply increase of message volume, third generation partner program (the 3rd GenerationPartnership Project, be called for short 3GPP) authorize frequency range to seem more and more to be not enough to provide higher network capacity, and then, how under the help of authorizing frequency range, to use unauthorized frequency range, what become current 3GPP discusses one of problem, and unauthorized frequency range is as 2.4GHz and 5GHz frequency range.Current mainly WiFi, bluetooth, radar, the systems such as medical treatment are in use.For authorizing the access technology of frequency range design, as Long Term Evolution (LongTerm Evolution, be called for short LTE) very high to the requirement of frequency range efficiency and Consumer's Experience optimization, be not suitable for using in unauthorized frequency range, and carrier aggregation (Carrier Aggregation is called for short CA) function makes that LTE technology department is deployed on unauthorized frequency range and becomes possibility.Therefore, 3GPP proposes the concept that LTE assists access technology (LTE Assisted Access is called for short LAA), authorizes the help of frequency range to use unauthorized frequency range by LTE.Wherein, unauthorized frequency range can have two kinds of working methods, and one is supplementary descending (Supplemental Downlink is called for short SDL), is exactly that frequency range is only used in downlink transfer, by carrier aggregation technology; Another kind is time division duplex (Time Division Duplex is called for short TDD) pattern, may be used for downstream transmission, can use logical by doubly-linked (Dual Connectivity is called for short DC), also can independently use.

The existing access technology used in unauthorized frequency range, as WiFi, has more weak antijamming capability.In order to avoid interference, rule is avoided in a lot of interference of WiFi system, as Carrier Sense Multiple Access/collision detection method (Carrier Sense Multiple Access/Collision Detection, be called for short CSMA/CA), its general principle is access point (the Access Point of WiFi, be called for short AP) or terminal transmission signaling or data before, AP or terminal whether is had in sending/receiving signaling or data around first Monitor detection, if had, then continue to monitor, do not have until listen to.If no, then generate a random number as back off time, in this back off time, if signaling or transfer of data do not detected, so after back off time terminates, AP or terminal can start to send signaling or data.As shown in Figure 1.

And LTE network ensure that interference level owing to there being good orthogonality, so the downstream transmission of base station and terminal need not consider whether have base station or terminal transmitting around.If whether have other equipment around also not considering when LTE uses in unauthorized frequency range in the unauthorized frequency range of use, so great interference will be brought to WiFi equipment.As long as because LTE has business just to transmit, without any monitoring rule, so WiFi equipment just cannot be transmitted when LTE has business to transmit, can only wait until that LTE business is transmitted, just can channel clear be detected, just can transmit.

So LTE is when using unauthorized frequency range, one of topmost key point guarantees that LAA can coexist with existing access technology (such as WiFi) on fair friendly basis, and then the mechanism proposing listem-before-talk (Listen Before Talk is called for short LBT) carrys out collision free.

Based on equipment (the Frame based equipment of frame, be called for short FBE) LBT mechanism as shown in Figure 2, wherein channel idle assessment (Clear Channel Assessment, be called for short CCA) periodically repeat detection time, if channel idle detected detection time at CCA, then busy channel.After Channel holding time, have idle (idle) time, in the idle time, sending point does not send signal and data, is convenient to other sending point and seizes channel.After the idle time, occur again CCA detection time, if channel busy detected, then not busy channel, until again detect channel when the CCA in next cycle occurs detection time.

If the CCA based on the LBT of frame structure between operator cannot stagger detection time, if that is the LBT time of A with B operator identical, as shown in Figure 3.The LAA community of A operator and the LAA community of B operator all detect channel idle, so after the LBT time terminates, there are data in both simultaneously, collision will be produced like this, wherein, base station is comprised respectively in the LAA community of A operator and the LAA community of B operator, and the terminal in this base station range.

If but the CCA time of operator stagger, and periodically to repeat, then under easily making certain situation, the LAA community busy channel always of A operator, and the LAA community of B operator takies less than channel always, thus bring time delay and unfairness.As shown in Figure 4, because channel is detected above in the community of operator 1, so channel idle then busy channel detected, and channel always detects in operator 2 below, and now channel has been taken by operator 1, so operator 2 seizes for a long time less than channel, bring comparatively long time delay and unfairness.

The LBT mechanism that the present invention mainly introduces based on FBE requires on basis, realizes the Channel Detection of unauthorized frequency range.

Based on above-mentioned introduction, embodiments provide a kind of channel detection method of unauthorized frequency range.Refer to Fig. 5 a, the schematic flow sheet of the channel detection method of the unauthorized frequency range that Fig. 5 a provides for the embodiment of the present invention; As shown in Figure 5 a, a kind of channel detection method of unauthorized frequency range, can comprise:

501, whether network element device to detect in the period at destination channel free time assessment CCA the channel detecting unauthorized frequency range idle, the above-mentioned target CCA detection period is contained in CCA window detection time, above-mentioned CCA window detection time at least comprises N number of CCA and detects the period, and at least two different operators use above-mentioned N number of CCA to detect CCA different in the period and detect the period;

Under said network element equipment works in operator LAA community, can be base station or terminal, wherein, terminal be in base station range.

Wherein, CCA window detection time is specifically included in the CCA sense cycle of the frame structure of FBE, and CCA sense cycle includes CCA window detection time further, in CCA window detection time, include N number of CCA detect the period, in a CCA sense cycle, an operator only uses a CCA detection period in CCA window detection time to carry out Channel Detection, and to guarantee that in CCA window detection time at least two different operators use different CCA to detect the period, wherein, above-mentioned N be more than or equal to 2 positive integer.

Be understandable that, in a CCA sense cycle, comprise CCA detection window and Channel holding time and (idle) time free time.Therefore, after CCA detection window, also has Channel holding time and idle (idle) time.

It should be noted that if operator uses second CCA to detect the period, if so channel idle detected, from the 3rd CCA detects the period, transmit data, start busy channel.

502, when channel idle being detected, said network element equipment carries out transfer of data based on above-mentioned idle channel.

Above-mentioned data are transmitted in a frame format, specifically comprise signaling or data payload.

The embodiment of the present invention belongs to dynamic LBT mechanism by providing a kind of CCA section detection time, wherein, include N number of CCA in CCA window detection time and detect the period, the different CCA that different operators can use N number of CCA to detect in the period detects the period, and then network element device under operator LAA community then can detect the period whether detect channel idle by based target CCA, stagger from detection time, between the LAA community of minimizing different operators or the LAA community of operator is to the collision detection between WIFI, and the target CCA detection period that each operator uses in CCA window detection time is dynamic, that is different target CCA can be used in each CCA window detection time to detect the period, guarantee that the network element device be operated under the LAA community of different operators has fair Channel Detection probability, fair co-existence between the LAA community realizing different operators.

Be understandable that, in the above-described embodiments, the target CCA that operator uses in CCA window detection time detects the period can be pre-configured, and then as shown in Figure 5 b, another embodiment of the present invention additionally provides a kind of collocation method, can comprise:

511, in channel idle assessment CCA window detection time, configure N number of CCA and detect the period;

Wherein, above-mentioned N be more than or equal to 2 positive integer.

512, detect in the period at above-mentioned N number of CCA, detect the period at least two different operators configure different CCA.

The collocation method that Fig. 5 b provides can artificially be configured according to collocation strategy, this collocation strategy specifically arranges CCA window detection time in based on the CCA sense cycle of FBE frame structure, and in each CCA window detection time, configure N number of CCA detection period, then detect in the period at this N number of CCA and detect the period for different operators configures different CCA, wherein, in CCA window detection time, at least there is the CCA of two different operators to detect the period different, thus operator is staggered on detection time.

Further, when detecting the period to operator configuration CCA, detect in the period at above-mentioned N number of CCA, detect the period at least two different operators configure different CCA, and the CCA detection period that any one above-mentioned operator configures in continuous N above-mentioned CCA window detection time is not identical.Detect the period based on this collocation strategy configuration CCA, the CCA of certain operator can not be caused to detect the period always front, channel idle detected always, busy channel always, and the CCA of other operator detects the period always rear, can't detect channel idle always, always can not busy channel.

For example, as shown in Figure 6 a, the schematic diagram of CCA window detection time that provides for the embodiment of the present invention of Fig. 6 a; In Fig. 6 a, for 5 CCA sense cycle, be respectively A1, A2, A3, A4 and A5, each CCA sense cycle comprises CCA window detection time, therefore, 5 CCA sense cycle one have 5 CCA windows detection time, are respectively B1, B2, B3, B4 and B5, comprise 5 CCA in each CCA window detection time and detect the period, be respectively 1,2,3,4 and 5 according to its sequence of positions.Need now to detect the period for operator 1, operator 2 and operator 3 distribute target CCA in continuous 3 CCA windows detection time, wherein, it is 1 in the sequence of positions of CCA window detection time 1, CCA window detection time 2 and CCA window detection time 3 that the CCA of operator 1 detects the period, 2 and 3, recalculate in the sequence of positions of CCA window detection time 4, CCA window detection time 5 and CCA window detection time 6 (not marking in Fig. 6 a), be respectively 1,2 and 3, the like; Equally, it is 2 in the sequence of positions of CCA window detection time 1, CCA window detection time 2 and CCA window detection time 3 that the CCA of operator 2 detects the period, 3 and 1, recalculate in the sequence of positions of CCA window detection time 4, CCA window detection time 5 and CCA window detection time 6 (not marking in Fig. 6 a), be respectively 2,3 and 1, the like; It is 3 in the sequence of positions of CCA window detection time 1, CCA window detection time 2 and CCA window detection time 3 that the CCA of operator 3 detects the period, 1 and 2, recalculate in the sequence of positions of CCA window detection time 4, CCA window detection time 5 and CCA window detection time 6 (not marking in Fig. 6 a), be respectively 3,1 and 2, the like.

Wherein, the CCA of the operator 1 after configuration, operator 2 and operator 3 detects the period as shown in Figure 6 b, wherein, the CCA of each operator detects the sequencing of period in change, the CCA of certain operator can not be caused to detect the period always front, and channel idle detected always, can busy channel always, and other operator CCA detect the period rearward always, can't detect channel idle always, always can not busy channel situation occur.

It should be noted that, except above-mentioned collocation strategy, the present invention can also adopt other collocation strategy to be configured, and regardless of which kind of collocation strategy, as long as realize technique effect of the present invention, all belongs to protection scope of the present invention.

Also it should be noted that, relevant information is related at above-mentioned collocation strategy, comprise CCA sense cycle, CCA window detection time in this CCA sense cycle, each CCA CCA that window comprises detection time detect the period and detection period of the target CCA in CCA window detection time of distributing for operator, these information can be referred to as Channel Detection configuration information.Wherein, can Channel Detection configuration information be embedded in base station ic with a kind of collocation strategy or protocol mode, and then base station is when detecting that data need transmission, then can complete Channel Detection according to the target CCA detection period configured in above-mentioned collocation strategy, and when monitoring channel idle, carry out transfer of data based on the channel detected.

Certainly, to the Channel Detection configuration information be embedded in base station ic carries out rewriting operation with collocation strategy or protocol mode, such as, along with the increase of operator, when needing again for the operator configuration CCA detection period, then rewriting operation can also be carried out.

Due to above-mentioned, Channel Detection configuration information is embedded in base station ic with collocation strategy or protocol mode, therefore, configuration information can be sent to the terminal in its coverage by base station, so that terminal is when carrying out transfer of data, adopts the target CCA configured to detect the period and carrying out Channel Detection.

Therefore, on above-mentioned collocation method basis, in the present invention's enforceable mode, said network element equipment is specially base station, then detect in the period at destination channel free time assessment CCA the channel whether before the free time detecting unauthorized frequency range at network element device, also comprise step:

When detecting that data need transmission, above-mentioned base station is retrieved as from above-mentioned CCA window detection time the target CCA that the operator belonging to above-mentioned base station distributes and detects the period, operator belonging to above-mentioned base station uses different CCA to detect the period in continuous N above-mentioned CCA window detection time, and above-mentioned M is less than or equal to above-mentioned N.

Can find out, when detecting that in base station data need to transmit, whether the target CCA that the operator that can be adopted as its correspondence configures detects period detection channel idle, because the CCA detection period of each operator in continuous N CCA window detection time is not identical, thus the CCA of certain base station can not be caused to detect the period always front, channel idle detected always, busy channel always, and the CCA of base station under other operator or terminal detects the period always rear, can't detect channel idle always, always can not busy channel.

In corresponding above-described embodiment, network element device is the situation of base station, when network element device is terminal, in another enforceable mode of the present invention, said network element equipment detects in the period at destination channel free time assessment CCA the channel detecting unauthorized frequency range and whether comprises step before the free time:

S1, above-mentioned terminal receive the first Channel Detection configuration information that base station sends, and above-mentioned first Channel Detection configuration information at least comprises the detection period of the target CCA at above-mentioned CCA window detection time that CCA sense cycle and the operator for above-mentioned base station belonging to distribute;

S2, when detect data need transmission time, what above-mentioned terminal operator be retrieved as belonging to above-mentioned terminal from above-mentioned first Channel Detection configuration information distributed detects the period at the above-mentioned target CCA of above-mentioned CCA window detection time, operator belonging to above-mentioned terminal uses different CCA to detect the period in continuous N above-mentioned CCA window detection time, and above-mentioned M is less than or equal to above-mentioned N.

Be understandable that, for terminal, receive the first Channel Detection configuration information that base station sends, from the first Channel Detection configuration information, obtain target CCA detect the period, when detecting that data need transmission, whether idlely this target CCA is utilized to detect period detection channel.Thus can stagger detection time with the base station under other operator or terminal, reduce the collision detection between operator LAA community and between operator LAA community and WIFI.

Above-mentioned from describing the channel detection method unauthorized frequency range for operator configuration target CCA detects the angle of period in advance, network element device is detected the angle of period below from CCA window selection detection time CCA, introduce the channel detection method in unauthorized frequency range further.

Be appreciated that, in order to provide better Consumer's Experience to user, can by the CCA sense cycle in above-mentioned Channel Detection configuration information, CCA window detection time in this CCA sense cycle, and each CCA CCA detection period that detection time, window comprised, be embedded in base station ic with a kind of collocation strategy or protocol mode, be not that the period is detected at CCA window detection time configuration target CCA by operator in advance, therefore, when needing transmission data in base station, need the first select target CCA detection period from CCA window detection time, whether based target CCA detection period detection channel is idle again.

Due to above-mentioned, Channel Detection configuration information is embedded in base station ic with collocation strategy or protocol mode, therefore, configuration information can be sent to the terminal in its coverage by base station, so that terminal is when carrying out transfer of data, from CCA window detection time, select target CCA detect the period, whether based target CCA detects period detection channel idle.

Certainly, not identical in order to realize the CCA detection period of each operator in continuous N CCA window detection time, thus the CCA of certain operator can not be caused to detect the period always front, channel idle detected always, busy channel always, and the CCA of other operator detects the period always rear, can't detect channel idle always, always can not busy channel.Base station or terminal are when unrestricted choice target CCA from CCA window detection time detects the period, can with reference to above-mentioned collocation strategy (not repeating them here), namely each base station or terminal select different CCA to detect the period respectively in continuous N CCA window detection time.

Therefore, in another enforceable mode of the present invention, if said network element equipment is specially base station, then detects in the period at destination channel free time assessment CCA the channel whether before the free time detecting unauthorized frequency range at network element device, also comprise step:

When detecting that data need transmission, the period is detected from above-mentioned CCA window selection detection time target CCA in above-mentioned base station, and above-mentioned base station selects different CCA to detect the period in continuous N above-mentioned CCA window detection time, and above-mentioned M is less than or equal to above-mentioned N.

Correspondingly, when said network element equipment is terminal, in other enforceable modes of the present invention, detect in the period at destination channel free time assessment CCA the channel detecting unauthorized frequency range at said network element equipment and whether comprise step before the free time:

S3, above-mentioned terminal receive the second channel detection configuration information that base station sends, and above-mentioned second channel detects configuration information and at least comprises CCA sense cycle, CCA window detection time in above-mentioned CCA sense cycle, the above-mentioned CCA CCA detection period that detection time, window comprised;

S4, when detecting that data need transmission, above-mentioned terminal detects the period from above-mentioned CCA window selection detection time target CCA, and above-mentioned terminal selects different CCA to detect the period in continuous N above-mentioned CCA window detection time, and above-mentioned M is less than or equal to above-mentioned N.

Be understandable that, for terminal, receive the second channel detection configuration information that base station sends, detect configuration information according to second channel, from CCA window detection time, select target CCA detects the period.

Refer to Fig. 7, another embodiment of the present invention additionally provides a kind of channel detection method of unauthorized frequency range, can comprise:

701, whether network element device to detect at the CCA of the first channel idle assessment CCA sense cycle the channel detecting unauthorized frequency range in the period idle;

Wherein, said network element equipment can be base station or terminal,

702, when channel idle not detected, said network element equipment determines whether detection number of times channel idle not detected meets pre-set threshold value;

703, when above-mentioned detection number of times meets above-mentioned pre-set threshold value, an above-mentioned CCA sense cycle is replaced by the 2nd CCA sense cycle by said network element equipment, and whether detect at the CCA of above-mentioned 2nd CCA sense cycle the channel detecting above-mentioned unauthorized frequency range in the period idle, above-mentioned 2nd CCA sense cycle is less than an above-mentioned CCA sense cycle;

704, when channel idle being detected, said network element equipment carries out transfer of data based on above-mentioned idle channel.

The LBT mechanism that a kind of CCA sense cycle is variable is provided in the embodiment of the present invention, wherein, whether the network element device under operator LAA community first adopts a CCA sense cycle idle to the channel detected under unauthorized frequency range, when a certain network element device does not detect that the detection number of times of channel idle meets pre-set threshold value, this network element device can change a CCA sense cycle into the 2nd CCA sense cycle, and then whether the channel adopting the 2nd CCA sense cycle again to detect under unauthorized frequency range is idle, because the 2nd CCA sense cycle is less than a CCA sense cycle, namely by shortening the cycle of Channel Detection, thus improve the number of times of Channel Detection, for network element device provides fair detection probability, fair co-existence between the LAA community realizing different operators, and the network element device that can't detect idle channel is after changing CCA sense cycle, namely can stagger detection time with the CCA of other network element device on CCA detection time, between minimizing operator LAA community and operator LAA community is to the collision detection of WIFI.

Alternatively, above-mentioned pre-set threshold value for the positive integer being more than or equal to 2, can specifically depend on that traffic carrying capacity or business are to the susceptibility of time delay, and such as traffic carrying capacity is large or business is strong to delay sensitive, then pre-set threshold value is less; Otherwise pre-set threshold value can be larger.Pre-set threshold value can adopt semi-static mode to configure.

If pre-set threshold value is 2, that is continuous when utilizing for 2 times a CCA sense cycle to can't detect idle channel, be just replaced with the 2nd CCA sense cycle, to shorten sense cycle.

Alternatively, an above-mentioned CCA sense cycle can be the multiple of the 2nd CCA sense cycle, such as more than 2 times or 2 times.

Be understandable that, a CCA sense cycle, a CCA sense cycle can not detected that the Channel Detection configuration information such as detection number of times and the 2nd CCA sense cycle of channel idle is embedded in base station ic with a kind of collocation strategy or protocol mode continuously equally.Wherein, the continuous of a CCA sense cycle does not detect that the detection number of times of channel idle is above-mentioned pre-set threshold value.

Therefore, corresponding to base station side, in some enforceable modes of the present invention, a kind of channel detection method of unauthorized frequency range can comprise: whether the channel detecting unauthorized frequency range in the period is detected at the CCA of the first channel idle assessment CCA sense cycle in base station idle; When channel idle not detected, above-mentioned base station determines whether detection number of times channel idle not detected meets pre-set threshold value; When above-mentioned detection number of times meets above-mentioned pre-set threshold value, an above-mentioned CCA sense cycle is replaced by the 2nd CCA sense cycle by above-mentioned base station, and whether detect at the CCA of above-mentioned 2nd CCA sense cycle the channel detecting above-mentioned unauthorized frequency range in the period idle, above-mentioned 2nd CCA sense cycle is less than an above-mentioned CCA sense cycle; When channel idle being detected, transfer of data is carried out based on above-mentioned idle channel in above-mentioned base station.

For end side, need to obtain the 3rd Channel Detection configuration information, the detection number of times that the 3rd Channel Detection configuration information comprises an above-mentioned CCA sense cycle, a CCA sense cycle does not detect channel idle continuously and the 2nd CCA sense cycle from base station.Therefore, in other enforceable modes of the present invention, detect at the CCA of the first channel idle assessment CCA sense cycle the channel detecting unauthorized frequency range in the period at said network element equipment and whether comprise step before the free time: above-mentioned terminal receives the 3rd Channel Detection configuration information that base station sends.

For example, as shown in Figure 8 a, operator 1 adopts CCA sense cycle T _l(T _l=10ms) CCA detect the period detect channel whether idle, channel idle detected, and send data for continuous 4 times.Operator 2 is a T in N continuous=3 _lin detect channel busy, next from the 4th sense cycle by T _lbe replaced with T _s(T _s=2ms), at ensuing 5th T _sin, this CCA detects the period and just in the time in free time (idle) of operator 1, then detects channel idle, and send data, and by T _sbe replaced with T _l.

Be understandable that, above-mentioned 3rd Channel Detection configuration information can also comprise the detection number of times that the 2nd CCA sense cycle does not detect channel idle continuously, when employing the 2nd CCA sense cycle does not detect that the detection number of times of idle channel meets the detection number of times that the 2nd CCA sense cycle provided in configuration information does not detect channel idle continuously, then the 2nd CCA sense cycle is transformed into a CCA sense cycle, or, the 2nd CCA sense cycle can also be replaced with the 3rd less CCA sense cycle.

It should be noted that, the limit that CCA sense cycle shortens is exactly that the CCA equaled in the cycle in CCA sense cycle detects the period.

When CCA sense cycle equals the CCA detection period, being in fact exactly become the existing LBT based on LBE mechanism, namely when channel busy being detected, selecting random number N=1, continue to detect, as long as channel idle, then a busy channel detected always.

Wherein, the LBT based on LBE is machine-processed as follows shown in Fig. 8 b: the LBT mechanism based on LBE is aperiodic, as long as there are data to need transmission, then trigger CCA and detects, if the CCA detection free time, then and horse transmitting data; If channel busy detected, then get a random number N, the span of N is 1 span arriving q, q is 4 to 32.Fig. 9 display be the situation of q=16, at this moment, when channel idle being detected, the maximum holding time of channel is (13/32) * q=6.5ms.Then after 6.5ms, taking window to compete (extended CCA) mechanism, is namely also random value N, the scope of N is 1 to 16, if value is 8, then represents and detect in the period at ensuing continuous print CCA, each CCA detects the period will detect channel, if channel idle detected, then N-1, if channel busy detected, then N is constant, when N is 0, send signaling or data.

Therefore, the limit that CCA sense cycle shortens detects the period for equaling CCA, in fact just becomes the mechanism of the LBT based on LBE of random number N=1.That is detect in the period at ensuing CCA, as long as once CCA detects the free time, then horse transmitting data.
