Description
Technical field
The present invention relates to the communications field, particularly relate to a kind of unlicensed spectrum channel detection method and device.
Background technology
Along with the sharply increase of message volume, 3GPP (3rdGenerationPartnershipProject, third generation partner program are called for short 3GPP) authorizes frequency spectrum to seem and is more and more not enough to provide higher network capacity.In order to improve the utilization of frequency spectrum resource further, 3GPP is just discussing how under the help of authorizing frequency spectrum, to use unlicensed spectrum, as 2.4GHz and 5GHz frequency range.The systems such as the current mainly WiFi of these unlicensed spectrum (WirelessFidelity, Wireless Fidelity are called for short WiFi), bluetooth, radar and medical treatment are in use.In general, for authorizing the access technology of frequency range design, as LTE (LongTermEvolution, Long Term Evolution, be called for short LTE) be not suitable for using in unauthorized frequency range, because the requirement that LTE access technology is optimized spectrum efficiency and Consumer's Experience is very high.But carrier aggregation function allows and LTE is deployed in unlicensed spectrum becomes possibility.3GPP proposes the concept of LAA (LTEAssistedAccess, the auxiliary access of Long Term Evolution, is called for short LAA), authorizes the help of frequency spectrum to use unlicensed spectrum by LTE.And unlicensed spectrum can have two kinds of working methods, one is supplementary descending (SDL, SupplementalDownlink), is exactly that this frequency range is only used in downlink transfer; Another kind is TDD (TimeDivisionDuplexing, time division duplex are called for short TDD) pattern, comprises downstream transmission.Supplementing descending this situation can only be use by carrier aggregation technology.And tdd mode can use by DC (DualConnectivity), also can independently use.Be illustrated in fig. 1 shown below.
Compare WiFi, the LTE being operated in unlicensed spectrum has the ability to provide higher spectrum efficiency and larger coverage effect, allows data traffic authorize seamless switching between frequency spectrum and unlicensed spectrum based on same core net simultaneously.Concerning user, this means better broadband experience, higher speed, better stability and mobile facility.
The existing access technology used in unlicensed spectrum, such as WiFi, has more weak antijamming capability.In order to avoid interference, rule is avoided in a lot of interference of WiFi system, as CSMA/CA (CarrierSenseMultipleAccess/CollisionDetection, i.e. csma/collision detection method are called for short CSMA/CA).The general principle of this method is the AP (AccessPoint of WiFi, access point, be called for short AP) or terminal transmission signaling or data before, want whether have AP or terminal around first Monitor detection in sending/receiving signaling or data, 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.
And owing to there being good orthogonality to ensure that interference level in LTE network, so the downstream transmission of base station and user need not consider whether have base station or user transmitting around.If whether have other equipment around also not considering when LTE uses in unlicensed spectrum in use unlicensed spectrum, 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.
In order to the use unlicensed spectrum making the operator of LTE communication system orderly, be currently suggested a kind of LBT based on FBE mechanism, operation principle is: CCA (ClearChannelAssessment, be called for short CCA, channel idle detects) time cycle property repeats, if detect within the CCA time, channel is idle condition, then busy channel, after Channel holding time, there is a free time, at one's leisure, sending point does not send signal and data, is convenient to other sending point and seizes channel.After at one's leisure, occur again the CCA time, if detect, channel is busy condition, then not busy channel, until again detect channel when the next CCA time occurs.
But current scheme Problems existing is: if the CCA time of Liang Ge operator stagger, and periodically repeat, then there will be the LAA community busy channel always of an operator, and the LAA community of another operator seizes the situation less than channel all the time, thus causing each operator cannot fair play channel, data transmission delay increases.

S201, in listening period section, monitor the channel status of unlicensed spectrum channel, wherein, the cycle of monitoring is the period 1.
Concrete, LTE communication system can by the mode of carrier aggregation, unlicensed spectrum is distributed to designated cell, when base station in community and terminal utilize unlicensed spectrum channel (up channel or down channel) to transmit data (data comprise control signal and data service), first need the right to use of competing unlicensed spectrum channel, then could utilize unlicensed spectrum channel transmission data.The network equipment pre-sets listening period section, and listening period section is the time interval of certain length, and the cycle of monitoring is the period 1, and namely the appearance cycle of listening period section is the period 1, and the duration of two namely adjacent listening period sections is the period 1.When the network equipment has data to need to transmit, when listening period section arrives, monitor the channel status of unlicensed spectrum channel, channel status is divided into busy condition and idle condition, busy condition represents that unlicensed spectrum channel is by other hold facilities, now can not in unlicensed spectrum channel data; Idle condition represents unlicensed spectrum channel not by other hold facilities, now can in unlicensed spectrum channel data.Wherein, the network equipment is in the process monitoring unlicensed spectrum channel, and the frequency range of unlicensed spectrum channel can be preassigned frequency range, such as, specify the working frequency range of unauthorized frequency range as unauthorized frequency range of certain limit according to the bandwidth of community.
The network equipment is when determining that unlicensed spectrum channel is idle condition, take unlicensed spectrum channel certain time length, then discharge unlicensed spectrum channel certain time length, the network equipment transmits data in channel occupancy duration, in channel idle duration, do not transmit data.In embodiments of the present invention, the channel occupancy duration under the period 1 is called the first channel occupancy duration, and the channel idle duration under the period 1 is called the first channel idle duration; Channel occupancy duration under second round is called that second channel takies duration, and the channel idle duration under second round is second channel free time length.
S202, when a N continuous period 1, to listen to described unlicensed spectrum channel be busy condition, be second round by the period modulation of monitoring; Wherein, the described period 1 is greater than described second round, N >=2 and be integer.
Concrete, it is busy condition that the network equipment listens to unlicensed spectrum channel according to the period 1 in N number of listening period section, and N number of listening period section is continuous print listening period section, N >=2 and be integer.Such as: the network equipment is when according to the period 1, to listen to unauthorized band channels in listening period section be busy condition, and counter adds 1; The network equipment is when according to the period 1, to listen to unlicensed spectrum channel in listening period section be idle condition, timer resets, when the count value of counter reaches N, period 1 will be adjusted to second round, the appearance cycle of namely now monitoring is second round, namely the appearance cycle of listening period section is second round, and the period 1 is greater than second round.
Exemplary, period 1 is 4ms, second round is 2ms, N is 3, be that the number of times of busy condition reaches 3 times when listening to unlicensed spectrum channel continuously in listening period section according to the period 1, the period 1 of listening period section 4ms is adjusted to 2ms, and continuous representation multiple listening period section meets adjacent relation.By the adjustment in the appearance cycle of listening period section, the network equipment adopts higher frequency in listening period section, monitor the channel status of unlicensed spectrum channel, improve with this chance that network equipment competes unlicensed spectrum channel, meet the requirement competing unlicensed spectrum channel fairness between different operators.

See Fig. 3, be another schematic flow sheet of a kind of unlicensed spectrum channel detection method that the embodiment of the present invention provides, in embodiments of the present invention, the executive agent of unlicensed spectrum channel detection method can be base station, also can be terminal, hereinafter referred to as the network equipment, described method comprises:
S301, determine the value of N according to the data volume size of data to be transmitted and/or delay requirement; Wherein, described data volume waiting for transmission is larger and/or delay requirement is higher, then N is less.
Concrete, the network equipment obtains data volume size and/or the delay requirement of data to be transmitted, the value of N is determined according to the data volume size of data to be transmitted and/or delay requirement, the data volume size of N and data to be transmitted and/or delay requirement are negative correlation, namely the data volume of quantity to be transmitted is larger and/or delay requirement is higher (namely time delay is less), N is less, and the data volume of data to be transmitted is less and/or delay requirement is lower, and N is larger.Negative correlation comprises geometric ratio and reduces relation or equal difference minimizing relation, and the present invention is not restricted.
Such as, when the data volume size of data to be transmitted is 2M, arranging N is 5; When the data volume size of data to be transmitted is 1M, arranging N is 10.
Again such as, the delay requirement of data to be transmitted is for being not more than 2ms, and arranging N is 5; The delay requirement of data to be transmitted is for being not more than 5ms, and arranging N is 10.
Again such as, the data volume size of data to be transmitted is 2M, and delay requirement is for being not more than 2ms, and arranging N is 5; The data volume size of data to be transmitted is 1M, and delay requirement is for being not more than 5ms, and arranging N is 10.
Optionally, the method that the network equipment arranges N can also be: the network equipment is that N configures multiple candidate value, according to semi-static mode from multiple candidate value select target candidate value as the value of N.
Concrete, the network equipment obtains the dispatching cycle of semi-static mode, from the multiple candidate values preset, select a target candidate value as N according to dispatching cycle, wherein, from multiple candidate value, select target candidate value can be selected according to arrangement sequencing.
Such as, the cycle of semi-persistent scheduling is 2 hours, the network equipment for N configures multiple candidate value is in advance: 10,8,6,4, and the network equipment selected a candidate value as target candidate value every 2 hours from multiple candidate value, and the mode of selection can adopt the selection that circulates in order.
Optionally, the described period 1 is the integral multiple of described second round.
Such as, the period 1 is 2 times of second round, and the period 1 is 4ms, and second round is 2ms.
S302, in listening period section, monitor the channel status of unlicensed spectrum channel, wherein, the cycle of monitoring is the period 1.
Concrete, period 1 is appearance cycle of listening period section, listening period section is the time interval of preset duration, and the network equipment monitors the channel status of unlicensed spectrum channel according to the period 1 in listening period section, and the state of unlicensed spectrum channel is divided into idle condition and busy condition.The method of the channel status of network equipment identification unlicensed spectrum channel can be: the initial time t1 and the finish time t2 that determine current listening period section, the network equipment measures the t1 moment to the received power in the t2 moment, if when received power is greater than predetermined power value, determine that in current listening period section, unlicensed spectrum channel is busy condition; If when received power is not more than predetermined power value, determine that in current listening period section, unlicensed spectrum channel is idle condition.
S303, when a N continuous period 1, to listen to described unlicensed spectrum channel be busy condition, be second round by the period modulation of monitoring; Wherein, the described period 1 is greater than described second round, N >=2 and be integer.
Concrete, the network equipment listens to unlicensed spectrum channel in listening period section when being busy condition, and count value adds 1, and the network equipment listens to unlicensed spectrum channel in listening period section when being idle condition, and count value resets.When a N continuous period 1, to listen to unlicensed spectrum channel be busy condition, the network equipment will be adjusted to second round the period 1, N be more than or equal to 2 integer.
Exemplary, the initial value of counter is 0, N=3, it is busy condition that the network equipment listens to unlicensed spectrum channel for the 1st time according to the period 1, counter adds 1, and to obtain current count value be 1, it is idle condition that the network equipment listens to unlicensed spectrum channel for the 2nd time according to the period 1, timer resets and obtains current count value is 0, it is busy condition that the network equipment continuously listens to unlicensed spectrum channel at the 3rd time to the 5th according to the period 1, then to listen to unlicensed spectrum channel be continuously the number of times of busy condition is 3, reach 3, the period 1 of listening period section is adjusted to second round by the network equipment.
S304, according to when to listen to unlicensed spectrum channel described second round in listening period section be idle condition, take described unlicensed spectrum channel.
Concrete, the network equipment is according to when to listen to unlicensed spectrum channel second round in listening period section be idle condition, take unlicensed spectrum channel, two kinds of situations are divided into after the duration taking unlicensed spectrum channel terminates, for to enable a new listening period section after preset duration again, another kind of for enable new listening period section immediately.
S305, to determine that according to the first channel occupancy duration corresponding to described period 1 and the first channel idle duration second round, corresponding second channel took duration and second channel free time length.
Concrete, according to the first channel occupancy duration corresponding to period 1 and the first channel idle duration, the network equipment determines that the second channel under second round takies duration and second channel free time length.Wherein, determine that the method that second channel takies duration and second channel free time length can be: second channel takies duration and equals the first channel occupancy duration, and second channel free time length equals the first channel idle duration; Or second channel takies duration and is less than the first channel occupancy duration, and second channel free time length is less than the first channel idle duration, and the finish time of second channel free time length be no more than next adjacent period 1 under the initial time of listening period section.Because second channel takies before duration is positioned at second channel free time length, the finish time that therefore second channel takies duration be also no more than next adjacent period 1 under the initial time of listening period section.Preferably, finish time of second channel free time length coincides with the initial time of the listening period section under next adjacent period 1, and the finish time that second channel takies duration coincides with the initial time of second channel free time length.
Such as, see Fig. 4, when being idle condition for listening to unlicensed spectrum channel in the listening period section under second round of the embodiment of the present invention, second channel takies the method for adjustment of duration and second channel free time length, wherein, CCA represents listening period section, channeloccupancytime represents channel occupancy duration, idle represents channel idle duration, Opt.1 represents the detection sequential chart of the unlicensed spectrum channel of certain community of the first operator, Opt.2 represents the sequential chart of the unlicensed spectrum Channel Detection of certain community of the second operator, Opt.2othercell represents the sequential chart of the unlicensed spectrum Channel Detection of another community of the second operator.In Fig. 4, the listening period section of the first operator and the second operator does not overlap, and the listening period section on each community of same operator overlaps, and the first operator and the second operator are according to period 1 T
lthe channel status of unlicensed spectrum channel is monitored in listening period section, can find out, it is idle condition that first operator listens to unlicensed spectrum channel in first listening period section, unlicensed spectrum channel, after experience first channel occupancy duration and the first channel idle duration, starts the monitoring in the 2nd listening period section.When second operator monitors the channel status of unlicensed spectrum channel according to the period 1 in first listening period section, first listening period section is positioned at the first channel occupancy duration of the first operator, therefore the unlicensed spectrum channel that the second operator listens to is busy condition, because the relative position of the listening period section of the first operator and the second operator is fixing, therefore the first operator always can compete unlicensed spectrum channel, second operator but always cannot compete unlicensed spectrum channel, causes the two competition unfair.The N that second operator is arranged is 3, second operator is when according to the period 1, to listen to unlicensed spectrum channel be first busy condition, counter adds 1, it is the number of times of busy condition when reaching 3 that second operator listens to unlicensed spectrum channel continuously, and the second operator is by the period 1 T of listening period section
lbe adjusted to T second round
s, second round is less than the period 1.
Second operator is according to continuing the state monitoring unlicensed spectrum channel second round in listening period section, it is busy condition that second operator listens to unlicensed spectrum channel in the 4th listening period section, in the 5th listening period section, listen to unlicensed spectrum channel is idle condition, determine that the second channel under second round takies duration and second channel free time length, wherein, second channel takies duration and equals the first channel occupancy duration, and second channel free time length equals the first channel idle duration.
Again such as, see Fig. 5, for according to when to listen to unlicensed spectrum channel second round be idle condition, second channel takies the method for adjustment of duration and second channel free time length, it is idle condition that second operator listens to unlicensed spectrum channel in the 5th listening period section, obtain the listening period section under next adjacent period 1, because the unlicensed spectrum Channel Detection of each community is synchronously carried out, second operator is the appearance situation of the listening period section occurred the repetition period with period 1 according to self, determine and the listening period section under the adjacent next period 1 of the listening period section of the 5th under second round, namely the 4th listening period section under the period 1 in other communities is next adjacent listening period section, the finish time of second channel free time length is no more than the initial time of the 4th listening period section in other communities, and the finish time that second channel takies duration is also no more than the initial time of the 4th listening period section in other communities.The initial time being preferably the listening period section under period 1 adjacent with next finish time of second channel free time length overlaps, while second channel finish time of taking duration overlap with the initial time of second channel free time length.
Be understandable that, the cycle of the listening period section of the first operator and the second operator, the duration of listening period section, the first channel occupancy duration and the first channel idle duration can be equal, also can be unequal, in Fig. 4 and Fig. 5 for convenience of explanation, above-mentioned parameter value is all got equal, and operators different during practical application, when arranging above-mentioned parameter value, can be arranged as required.
It should be noted that, second operator is when N continuous listens to unlicensed spectrum channel a second round, again the second round of listening period section can be adjusted to the value less period 3, wherein under the period 3 N can be equal with the N under second round in the embodiment of the present invention, second round can be the integral multiple of period 3, or arrange N under the period 3 and period 3 according to communication system requirements, the present invention is not restricted.
S306, at the end of described second channel takies duration or described second channel free time length, described second round is adjusted to the described period 1.
Concrete, when taking unlicensed spectrum channel, when only configuration second channel takies duration, terminate to be will be adjusted to the period 1 when second channel takies duration second round; Or when taking unlicensed spectrum channel, when configuration second channel takies duration and second channel free time length, and second channel free time length is positioned at after second channel takies duration, at the end of second channel free time length, the second round of listening period section is adjusted to the period 1 by the network equipment, the channel status of unlicensed spectrum channel is monitored in network equipment continuation in listening period section according to the period 1, namely continue to perform S301.
Described period 1, described first channel occupancy duration, described first channel idle duration, the value of described N, described second round, described second channel are taken duration and described second channel free time length by RRC signaling to terminal by S307, base station, to make described terminal according to the value of described period 1, described N and the state detecting up channel described second round, and take according to described first channel occupancy duration, described first channel idle duration, described second channel the holding time that duration and described second channel free time length control up channel.Be understandable that, when base station is by above-mentioned parameter notification terminal, also can pass through other signalings or message informing terminal, the present invention is not restricted.
Concrete, in LTE communication system, the detection of down channel in base stations being in charge community, terminal is responsible for the detection of intra-cell uplink channel, and cell operation is in unlicensed spectrum.Period 1, the first channel occupancy duration, the first channel idle duration, the value of N, second round, second channel are taken duration and second channel free time length by RRC (RadioResourceControl by base station, wireless heterogeneous networks, being called for short RRC) signaling is to terminal, terminal monitors the state of up channel according to the value of period 1, N and second round, and takies according to the first Channel holding time, the first channel idle duration, second channel the holding time that duration and second channel free time length control up channel.
Detailed process can be: terminal monitors the channel status of up channel according to the period 1 in listening period section, when up channel is idle condition, the holding time of up channel is the first channel occupancy duration, the free time of up channel is the first channel idle duration, terminal is when a N continuous period 1, to listen to unlicensed spectrum channel be idle condition, period 1 will be adjusted to second round, terminal monitors the channel status of up channel according to second round in listening period section, when listening to up channel and being idle condition, take up channel, and determine that the holding time of up channel is that second channel takies duration, the free time length of up channel is second channel free time length, at the end of second channel takies duration or second channel free time length, the period 1 will be adjusted to second round.
