Detailed description of the invention

Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to limit Determine the present invention.

The present invention provides the method for pre-emptively of a kind of unauthorized carrier wave.

Schematic flow sheet with reference to method for pre-emptively one embodiment that Fig. 1, Fig. 1 are the unauthorized carrier wave of the present invention.

In one embodiment, the method for pre-emptively of this unauthorized carrier wave includes:

Step S10, configuration is preset unauthorized carrier wave up and is taken attribute, descending takies attribute；

In the use of unauthorized carrier wave, need to avoid exceeding clear channel assessment (CCA) (Clear Channel Assessment, is called for short CCA) thresholding time be simultaneously used in unauthorized carrier wave existing website and be currently in use Unauthorized carrier wave, be otherwise likely to result between system interfering with each other.So awarding for non-in some areas Power carrier wave compulsive requirement supports listem-before-talk (Listen before Talk is called for short LBT) function, i.e. makes Before certain unauthorized carrier wave, need to first carry out CCA, non-award if it find that there is equipment to be currently in use this Power carrier wave, or the signal energy of detection is more than CCA thresholding, then postpone to access.If it find that channel is empty Spare time, or the signal energy of detection is less than CCA thresholding, then take this unauthorized carrier wave.

In the present embodiment, before execution CCA uses unauthorized carrier wave, it is pre-configured with default unauthorized Carrier wave up takies attribute, descending takies attribute, and wherein, it can be the most non-for presetting unauthorized carrier wave Authorize carrier wave, it is possible to for candidate can multiple unauthorized carrier wave.Configuration to presetting unauthorized carrier wave can It is not according to up-downgoing service conditions, frequency range distribution situation, geographical location circumstances, time slot distribution situation etc. Take attribute with unauthorized carrier wave collocating uplink, descending take attribute, seize for follow-up and use.

Step S20, based on configuration up take attribute and descending takies attribute, to default unauthorized load Ripple carries out seizing of up-link carrier and descending carrier.

Take for different unauthorized carrier wave collocating uplinks attribute, descending take attribute after, can be based on joining That puts up take attribute and descending takies attribute, and default unauthorized carrier wave carries out up-link carrier and descending Seizing of carrier wave.As when up-link carrier seized by needs, up the unauthorized of attribute can be taken being configured to Carrier wave performs CCA, to seize up-link carrier in the up unauthorized carrier wave taking attribute；At needs When seizing descending carrier, CCA can be performed in being configured to the descending unauthorized carrier wave taking attribute, with The descending unauthorized carrier wave taking attribute seizes descending carrier.

The present embodiment by different unauthorized carrier waves up is taken attribute, the descending attribute that takies carries out district Distribution is put, and based on different unauthorized carrier waves up can take attribute, descending take on attribute independent carries out Row, the seizing of descending carrier, not only reduce robbing of up in different unauthorized carrier waves, descending carrier Account for scope, and up, the descending carrier of unauthorized carrier wave will not be made to carry out, between seizing, impact of vying each other, Improve to rob in unauthorized carrier wave simultaneously and account for the probability that up, descending carrier carries out data transmission, Achieve seizing of up in unauthorized carrier wave, descending carrier more efficiently.

Further, in other embodiments, above-mentioned steps S10 may include that

In the present embodiment, when there being the available unauthorized carrier wave of N number of candidate, can be to N number of unauthorized carrier wave It is grouped, selects M1 unauthorized carrier wave as uplink carrier group, select M2 unauthorized carrier wave to make For downstream carrier group, wherein, the M1 in uplink carrier group unauthorized carrier wave with in downstream carrier group Do not intersect mutually between M2 unauthorized carrier wave.And M1 carrier wave in described uplink carrier group is used for Transmitting uplink data；M2 carrier wave in described downstream carrier group is used for downlink data transmission.On the most described M1 carrier wave in row carrier wave set is seized as up-link carrier, to carry out transmitting uplink data for follow-up；Described M2 carrier wave in downstream carrier group is seized as descending carrier, to carry out downlink data transmission for follow-up.

Further, also a up-downgoing carrier wave set can be configured in default some unauthorized carrier wave, on this M3 in downstream carrier group unauthorized carrier wave can carry out dynamic according to the change of up-downgoing business Configuration, M3 carrier wave in described up-downgoing carrier wave set be both available for follow-up seize carry out for up-link carrier on Row data are transmitted, it is possible to seize as descending carrier for follow-up to carry out downlink data transmission.

Further, in order to strengthen the motility that unauthorized carrier wave is seized, some unauthorized carrier waves are being divided After uplink carrier group, downstream carrier group, also can be to the time slot configuration of the carrier wave in described uplink carrier group Preset descending time slot, the time slot configuration of the carrier wave in described downstream carrier group is preset ascending time slot.Due to M1 carrier wave in described uplink carrier group is only capable of seizing as up-link carrier for follow-up to carry out upstream data Transmission, and M1 carrier wave in described uplink carrier group cannot be used brief for assisting to transmit some The default descending auxiliary signal of data dispatch, therefore, by the carrier wave in described uplink carrier group time Descending time slot is preset in gap configuration, can use the carrier wave being in default descending time slot in described uplink carrier group Carry out presetting the transmission of descending auxiliary signal.Same, it is possible to by described downstream carrier group The time slot configuration of carrier wave presets ascending time slot, can use described downstream carrier group is in default up time The carrier wave of gap carries out presetting the transmission of up auxiliary signal.

In the present embodiment, unauthorized carrier wave up is taken attribute, the descending attribute that takies can be by base station eNB Configuring, after having configured, by up taking attribute, the descending configuration information such as attribute that takies sends Notify, to UE, to enter one to user equipment (UE), such as eNB by the packet configuration information of some unauthorized carrier waves Step ground, eNB also can notify to adjacent base station and/or other non-LTE system packet configuration information, as Wi-Fi system etc., it is also possible to packet configuration information is notified to adjacent base station and/or other non-LTE by UE System.

Further, above-mentioned steps S20 may include that

Carrier wave in described uplink carrier group is carried out clear channel assessment (CCA), by low in described uplink carrier group In preset channel assessment thresholding or to be in the carrier wave of channel clear as up-link carrier and up to this Carrier wave is seized；Carrier wave in described downstream carrier group is carried out clear channel assessment (CCA), by described descending Less than preset channel assessment thresholding or be in the carrier wave of channel clear as descending carrier in carrier wave set, And this descending carrier is seized.

In the present embodiment, after the packet configuration completing some unauthorized carrier waves, eNB and/or UE exist M1 carrier wave in described uplink carrier group, the enterprising line space of M2 carrier wave in described downstream carrier group are not busy Channel estimating i.e. performs CCA to seize up-link carrier, descending carrier, to carry out upstream data, lower line number According to transmission.

Specifically, when seizing up-link carrier, typically by UE configuration information based on eNB described up M1 carrier wave enterprising line space channel assessment in carrier wave set i.e. performs CCA, by described uplink carrier group In less than preset channel assessment thresholding or be in the carrier wave of channel clear as up-link carrier, and to this Up-link carrier is seized, for the transmission of UE upward signal.Performed CCA by UE, be conducive to solving The certainly hidden node problem of UE periphery.Also can be performed CCA by eNB to carry out the resource of up-link carrier and seize, It is subsequently used for the scheduling that upward signal sends.When seizing descending carrier, typically by eNB based on configuration information CCA is performed on M2 carrier wave in described downstream carrier group, pre-by described downstream carrier group is less than If channel assessment threshold or be in the carrier wave of channel clear as descending carrier, and to this descending carrier Seize, for the transmission of eNB downstream signal.Performed CCA by eNB, advantageously account for eNB The hidden node problem of periphery, is also beneficial to eNB and quickly performs taking and dispatching of described unauthorized carrier wave. Also the resource that eNB execution CCA can be assisted to carry out descending carrier by UE is seized, and is subsequently used for downstream signal The scheduling sent.UE auxiliary CCA is conducive to UE to find the concealed nodes of periphery, thus is prevented effectively from The interference problem that concealed nodes is possible.

M3 in up-downgoing carrier wave set unauthorized carrier wave is seized, in one embodiment, eNB Can the uplink/downlink attribute of M3 carrier wave in semi-static or dynamic configuration described up-downgoing carrier wave set, eNB And/or UE performs CCA based on configuration information, in up-downgoing carrier wave set on described on M3 carrier wave Downstream carrier group assesses thresholding less than preset channel or is in the carrier wave of channel clear as uplink/downlink Carrier wave, sends for uplink/downlink signal after seizing.The preempt-mode of this uplink/downlink carrier wave is simple, up and down Row is coordinated convenient.In another embodiment, eNB and UE can perform CCA respectively, and currently When not having up transmission demand, UE can not perform CCA；When currently without descending transmission demand, eNB CCA can not be performed.If eNB finds that the unauthorized carrier wave in described up-downgoing carrier wave set is idle, but UE Discovery is busy or UE is currently without up transmission demand, then can take as descending carrier to carry out downstream signal Send；If UE finds that unauthorized carrier wave in described up-downgoing carrier wave set is idle, but eNB find busy or Person eNB currently without descending transmission demand, then takies as up-link carrier to carry out upward signal transmission；When When UE and eNB all finds the unauthorized carrier wave free time in described up-downgoing carrier wave set, described up-downgoing carries It can be following several ways that carrier occupancy in ripple group selects:

1, determine that uplink/downlink takies time slot and takies duration based on eNB scheduling.Can dispatch the most descending Take or the most up take；

2, in the unauthorized carrier occupancy phase in up-downgoing carrier wave set this described, under acquiescence first configuration Row take time slot/subframe, eNB schedule information further determine that this take total duration, up-downgoing each accounts for Duration and up-downgoing point switching time.For simplifying complexity, it is also possible to be pre-configured with in following parameter One or more: fixing always takies duration, the fixing allocation ratio of time up and down, up-downgoing switching Time point etc.；

3, it is pre-configured with eNB and UE to find when up-downgoing can use simultaneously, is used only for descending taking；

If 4 when now having the cyclical signal that upstream priority is higher to need to send, then acquiescence is this time the most up Take, or non-awarding of being assigned as in described up-downgoing carrier wave set of the time slots priority at upward cycle signal place The ascending time slot of power carrier wave；In like manner, if now there being the cyclical signal that descending priority is higher to need to send Time, then acquiescence is the most descending takies, or the time slots priority at downstream cycle signal place is assigned as on described The descending time slot of the unauthorized carrier wave in downstream carrier group.

Further, in order to strengthen the motility that unauthorized carrier wave is seized, some unauthorized carrier waves are being divided After uplink carrier group, downstream carrier group, also pre-to the time slot configuration of the carrier wave in described uplink carrier group If descending time slot, the time slot configuration of the carrier wave in described downstream carrier group is preset ascending time slot.So, M1 carrier wave in described uplink carrier group can not only be seized as up-link carrier for follow-up to carry out upper line number According to scheduling, it is possible to use the carrier wave being in default descending time slot in described uplink carrier group is default to transmit Descending auxiliary signal, wherein, in described uplink carrier group, the default descending time slot of configuration is generally configured to week The descending time slot resource of phase property, and descending time slot resource will not be occupied for ascending time slot, utilizes and sets in advance The default descending auxiliary signal of the carrier-wave transmission of row time slot is generally used for descending community and finds signal and/or reserve The transmission of signal etc., finds that signal may be used for carrier wave/community and finds and measure, and preserved signal can assist UE carrier occupancy is reserved.Same, M2 carrier wave in described downstream carrier group can not only be robbed for follow-up Account for as descending carrier to carry out downlink data dispatching, it is possible to use described downstream carrier group is in default The carrier wave of ascending time slot transmits default up auxiliary signal, wherein, configuration in described downstream carrier group Default ascending time slot is generally configured to periodic ascending time slot resource, and ascending time slot resource will not be occupied With for descending time slot.Such as in described downstream carrier group, configuration section presets ascending time slot, utilizes described The carrier wave being in default ascending time slot in downstream carrier group measures the default up auxiliary such as signal to send SRS Signal, eNB obtains channel information based on channel reciprocity, and the scheduling of auxiliary downstream data channel sends.

Further, in other embodiments, above-mentioned steps S10 may include that

In the present embodiment, the unauthorized carrier wave of each candidate is configured by time slot, configure each non-award The time slot of power carrier wave includes ascending time slot, descending time slot and/or uplink and downlink timeslot.Line number in needs transmission According to time, the unauthorized carrier wave being in ascending time slot is carried out clear channel assessment (CCA), ascending time slot will be in Unauthorized carrier wave assesses thresholding less than preset channel or is in the carrier wave of channel clear as up load Ripple, and this up-link carrier is seized carry out transmitting uplink data；When needs transmission downlink data, The unauthorized carrier wave being in descending time slot is carried out clear channel assessment (CCA), the unauthorized of descending time slot will be in Less than preset channel assessment thresholding or be in the carrier wave of channel clear as descending carrier in carrier wave, and This descending carrier is seized and carries out downlink data transmission.Wherein, it is in the non-of uplink and downlink timeslot to award Power carrier wave both can be preempted as up-link carrier, it is possible to is preempted as descending carrier.

Further, can also continue to be divided into the ascending time slot of each unauthorized carrier wave up gap in short-term and Up long time slot, wherein, the duration of up gap in short-term is less than up long time slot, is in up gap in short-term Unauthorized carrier wave is used for transmitting uplink control information；It is in the unauthorized carrier wave of up long time slot for transmitting Uplink user data；The descending time slot of each unauthorized carrier wave is divided into descending gap in short-term and descending long time Gap, wherein, the duration of descending gap in short-term is less than descending long time slot, is in the unauthorized load of descending gap in short-term Ripple is used for transmitting Downlink Control Information；It is in the unauthorized carrier wave of descending long time slot for transmitting downlink user Data.

Further, above-mentioned steps S20 can also include:

When needs transmission uplink user data, the unauthorized carrier wave being in up long time slot is carried out the free time Channel estimating, will be in the unauthorized carrier wave of up long time slot less than preset channel assessment thresholding or is in The unauthorized carrier wave of channel clear is as up-link carrier, and seizes this up-link carrier；When needing During down user data to be transmitted, the unauthorized carrier wave being in descending long time slot is carried out clear channel assessment (CCA), To be in the unauthorized carrier wave of descending long time slot less than preset channel assessment thresholding or be in channel idle shape The unauthorized carrier wave of state is as descending carrier, and seizes this descending carrier.

When needs transmitting uplink control information, using be in up gap in short-term unauthorized carrier wave as up Carrier wave, and this up-link carrier is seized；When needs transmission Downlink Control Information, will be in descending The unauthorized carrier wave of gap is as descending carrier in short-term, and seizes this descending carrier.

Specifically, it is provided with a unauthorized carrier wave A, eNB and configures described unauthorized carrier wave A when comprising up Gap T_{_UL}, descending time slot T_{_DL}And uplink and downlink timeslot T_{_UL_DL}.Further, ascending time slot T_{_UL}Divide For up gap T in short-term_{_UL_1}With up long time slot T_{_UL_2}, descending time slot T_{_DL}It is divided into descending gap in short-term T_{_DL_1}With descending long time slot T_{_DL_2}。T_{_UL_1}And T_{_UL_2}Separate configurations, T_{_DL_1}And T_{_DL_2}Independently join Put.Ascending time slot T_{_UL}It is only used for upward signal to send, descending time slot T_{_DL}It is only used for downstream signal to send, T_{_UL_DL}Can be used for uplink and downlink signal to send.

T_{_UL_1}For up gap in short-term, it is used for the necessary the most various control signal of ascending control information and/or reference The transmission of signal.T_{_UL_1}It is configurable to 0, does not the most configure described up gap in short-term.Such as, allowing Configure the scene of short control information (short control signalling is called for short SCS), according to SCS requirement The time less than 5% that only takes up within the 50ms observation period for T_{_UL_1}.In one embodiment, Described up gap T in short-term_{_UL_1}CCA can not be performed and i.e. send the upward signal of necessity, can be timely The important the most various control signal of ascending control information and/or reference signal etc. are timely transmitted to eNB, carry Rise systematic function.Described up gap T in short-term_{_UL_1}The cycle that is generally configured to occurs.In another embodiment In, CCA can be performed and take the carrier wave transmission for ascending control information, only take up up gap in short-term every time T_{_UL_1}.Typically performed CCA by UE, seize up gap T in short-term_{_UL_1}.ENB can assist UE to hold Row CCA, assists UE to solve the hidden node problem in up transmission signal.

Same, T_{_DL_1}For descending gap in short-term, it is used for the necessary the most various control signal of Downlink Control Information And/or the transmission of reference signal.T_{_DL_1}It is configurable to 0, does not the most configure described descending gap in short-term.Such as, Allowing the scene of configuration SCS, only taking up less than 5% within the 50ms observation period according to what SCS required Time for T_{_DL_1}.In one embodiment, described descending gap T in short-term_{_DL_1}Can not perform CCA i.e. sends the downstream signal of necessity, can be timely the important the most various control of Downlink Control Information Signal and/or reference signal etc. are timely transmitted to UE, promote systematic function.Described descending gap T in short-term_{_DL_1} The cycle that is generally configured to occurs.In another embodiment, CCA can be performed and take carrier wave for descending The transmission of control information, only takes up descending gap T in short-term every time_{_DL_1}.Typically performed CCA by eNB, rob Account for descending gap T in short-term_{_DL_1}.UE can assist eNB to perform CCA, assists eNB to solve descending transmission Hidden node problem in signal.

Above-mentioned T_{_UL_1}And T_{_DL_1}Time slot, can be separately configured T_{_UL_1}Time slot, for ascending control information Transmission, does not has descending T_{_UL_1}Time slot configuration demand；Or T can be separately configured_{_DL_1}Time slot, under being used for Row control information is transmitted, and does not has descending T_{_DL_1}Time slot configuration demand, such as transmission is under community finds Row finds signal.T_{_UL_2}And T_{_DL_2}Time slot is respectively used to the transmission of uplink and downlink user data, typically Take duration continuously more than T_{_UL_1}And T_{_DL_1}Time slot.T_{_UL_2}And T_{_DL_2}The relation of time slot has the most several The mode of kind:

1、T_{_UL_2}And T_{_DL_2}Time slot is arranged in nonoverlapping time period independently of one another, each independently takies. Such as eNB performs CCA and takies T_{_DL_2}Time slot, UE performs CCA and takies T_{_UL_2}Time slot.So join Put more flexible, it is not necessary to process T_{_UL_2}And T_{_DL_2}Rapport between time slot.

2、T_{_UL_2}And T_{_DL_2}The frame structure of the continuous binding configuration of time slot, the frame structure such as configured is: T_{_UL_2}Time slot adds T_{_DL_2}Time slot；Or T_{_DL_2}Time slot adds T_{_UL_2}Time slot.Generally preferably use LTE Tdd frame structure.Further, for improving the utilization rate of unauthorized carrier resource, can be with configuration section Predetermined ascending time slot reconfigures as descending, or the predetermined descending time slot of configuration section reconfigures as up. ENB and/or UE seizes respectively according to the uplink and downlink timeslot of configuration, is in the unauthorized carrier wave of ascending time slot Will not seize as descending carrier, the unauthorized carrier wave being in descending time slot will not be seized as up-link carrier.

If T_{_UL_1}Time slot and T_{_UL_2}Have coincidence between time slot, then configuration uses T_{_UL_2}Time slot.For T_{_UL_1}This time of time slot needs the signal of transmission to have following several candidate processes mode:

(1)、T_{_UL_1}The signal of this needs transmission of time slot can be at T_{_UL_2}Slot transmission, as far as possible Do not interrupt this T_{_UL_1}Time slot needs the signal of transmission, improves described T_{_UL_1}Time slot needs to transmit signal Reliability.

(2) this T, is interrupted_{_UL_1}This time of time slot needs the signal of transmission.Because T_{_UL_2}Time slot also needs Transmit the uplink user data originally needing transmission, if transmit T simultaneously_{_UL_1}The signal of time slot, can be right T_{_UL_2}The uplink user data transmission of time slot produces impact, the impact of such as resource overhead.

ENB explicitly or implicitly notifies that UE uses which kind of mode above-mentioned to transmit, and such UE is according to eNB's Configuration mode carries out upward signal transmission, and eNB processes, based on configuration mode reception, the up letter that UE sends Number.

Same, if T_{_DL_1}Time slot and T_{_DL_2}Have coincidence between time slot, then configuration uses T_{_DL_2}Time slot. For T_{_DL_1}This time of time slot needs the signal of transmission to have following several candidate processes mode:

(1)、T_{_DL_1}The signal of this needs transmission of time slot can be at T_{_DL_2}Slot transmission, as far as possible Do not interrupt this T_{_DL_1}Time slot needs the signal of transmission, improves described T_{_DL_1}Time slot needs to transmit signal Reliability.

(2) this T, is interrupted_{_DL_1}This time of time slot needs the signal of transmission.Because T_{_DL_2}Time slot also needs Transmit the down user data originally needing transmission, if transmit T simultaneously_{_DL_1}The signal of time slot, can be right T_{_DL_2}The down user data transmission of time slot produces impact, the impact of such as resource overhead.

ENB explicitly or implicitly notifies that UE uses which kind of mode above-mentioned to transmit, and such eNB is according to configuration side Formula carries out downstream signal transmission, and UE processes, based on eNB configuration mode reception, the downstream signal that eNB sends.

If T_{_UL_1}Time slot and T_{_DL_2}Coincidence is had, for T between time slot_{_UL_1}This needs transmission of time slot Signal have following several candidate processes mode:

(1), configuration uses T_{_DL_2}Time slot, interrupts this T_{_UL_1}This time of time slot needs the signal of transmission. Because general T_{_UL_1}The signal of slot transmission is ascending control information such as measuring reference signals etc., terminal certain Transmission, it is also possible to utilize the historical information of last time, or utilize the signal measurement of the transmission of next time.And can To make full use of T_{_DL_2}The more down user data of slot transmission.

(2), general T_{_DL_2}Time slot duration is more than T_{_UL_1}Time slot.Configuration uses T_{_DL_2}Time slot, but with Time reserve T_{_DL_2}Part-time in time slot is used for T_{_UL_1}Time slot.General T_{_UL_1}Time slot position is according in advance If period position be arranged in T_{_DL_2}In time slot, simultaneously need to configuration UE and eNB up-downgoing switching Time.This mode does not affect T_{_UL_1}The signal of slot transmission, it is provided that more multi-configuration T_{_DL_2}Slot transmission Chance.

If T_{_DL_1}Time slot and T_{_UL_2}Coincidence is had, for T between time slot_{_DL_1}This needs transmission of time slot Signal have following several candidate processes mode:

(1), configuration uses T_{_UL_2}Time slot, interrupts this T_{_DL_1}This time of time slot needs the signal of transmission. Because general T_{_DL_1}The signal of slot transmission is Downlink Control Information such as measuring reference signals etc., terminal certain Transmission, it is also possible to utilize the historical information of last time, or utilize the signal measurement of the transmission of next time.And can To make full use of T_{_UL_2}The more uplink user data of slot transmission.

(2), general T_{_UL_2}Time slot duration is more than T_{_DL_1}Time slot.Configuration uses T_{_UL_2}Time slot, but with Time reserve T_{_DL_2}Part-time in time slot is used for T_{_DL_1}Time slot.General T_{_DL_1}Time slot position is according in advance If period position be arranged in T_{_UL_2}In time slot, simultaneously need to configuration UE and eNB up-downgoing switching Time.This mode does not affect T_{_DL_1}The signal of slot transmission, it is provided that more multi-configuration T_{_UL_2}Slot transmission Chance.

It should be noted that preferred disposition T in the present embodiment_{_DL_2}Time slot and T_{_UL_1}Time slot is misaligned, excellent Arrangement T_{_UL_2}Time slot and T_{_DL_1}Time slot is misaligned, thus reduces the impact between different time-gap, reduces real Existing complexity.Above-mentioned each time slot configuration can be readjusted join based on the change of up-downgoing business demand Put, and notified UE by eNB.

Further, eNB and/or UE according to the time slot distribution structure being pre-configured with as configuration up time Gap, descending time slot and up gap in short-term, up long time slot, descending gap in short-term, descending long time slot, perform CCA, carries out up-link carrier, the seizing of descending carrier.The unauthorized carrier wave being in ascending time slot only understands quilt Take as up-link carrier, and for transmitting uplink data；The unauthorized carrier wave being in descending time slot only understands quilt Take as descending carrier, and for downlink data transmission.If the unauthorized carrier wave of the ascending time slot of configuration does not has Having occupied for up-link carrier, eNB and/or UE also will not take this ascending time slot into descending time slot； In like manner, if the unauthorized carrier wave of the descending time slot of configuration does not has occupied for descending carrier, eNB and/or UE Also this descending time slot will not be taken as descending time slot.Such as, ascending time slot, descending time slot configuration time Gap structure is, total duration 10ms, front 5ms keep for descending time slot, rear 5ms to keep for up.If it is front 5ms does not has occupied for descending carrier, then this time the 0-5ms blank of structure of time slot is not take up, only 6-10ms can be preempted as up-link carrier.

For T_{_DL_2}Time slot, is typically performed CCA by eNB and intercepts and seize.If eNB performs CCA Discovery is in T_{_DL_2}The unauthorized carrier wave of time slot meets CCA thresholding, then take as descending carrier, and use In downlink data transmission.ENB can configure UE auxiliary and perform T_{_DL_2}The CCA detection of time slot, auxiliary ENB determines whether to take this T_{_DL_2}Time slot.If this T_{_DL_2}Time slot CCA detection finds unavailable, ENB will not be configured to T_{_UL_2}Time slot perform CCA and intercept and seize as the descending time slot that takies, but Can be at next T_{_DL_2}Time slot attempts carrying out CCA and unauthorized carrier wave is seized, for downlink data transmission.

For T_{_UL_2}Time slot, is typically performed CCA by UE and intercepts and seize.If UE performs CCA Discovery is in T_{_UL_2}The unauthorized carrier wave of time slot meets CCA thresholding, then take as up-link carrier, and use In transmitting uplink data.System can configure eNB auxiliary and perform T_{_UL_2}The CCA detection of time slot, auxiliary Help and determine whether to take this T_{_UL_2}Time slot.If this T_{_UL_2}Time slot CCA detection finds unavailable, UE will not be set to T prewired_{_DL_2}Time slot perform CCA and intercept and seize as the up time slot that takies, and It is can be at next T_{_UL_2}Time slot attempts carrying out CCA and unauthorized carrier wave is seized, and passes for upstream data Defeated.

Further, if T_{_DL_1}Or T_{_UL_1}Time slot configuration is at certain T_{_DL_2}Time slot, can be only fitted to T_{_DL_2}Time slot position is attempted CCA and performs to seize；Or do not enforcing CCA and/or allowing to send out Send the region of SCS, do not perform CCA, directly take as T_{_DL_1}Or T_{_UL_1}Time slot, and send T_{_DL_1} Or T_{_UL_1}The signal that time slot is sent.If T_{_DL_1}Or T_{_UL_1}Time slot configuration is at certain T_{_UL_2}Time slot, Can be only fitted to T_{_UL_2}Time slot position is attempted CCA and performs to seize；Or do not enforcing CCA And/or allow to send the region of SCS, do not perform CCA, directly take as T_{_DL_1}Or T_{_UL_1}Time slot, And send T_{_DL_1}Or T_{_UL_1}The signal that time slot is sent.Especially at T_{_UL_2}/T_{_DL_2}Time slot is not seized into Merit and blank time, it is impossible to seize again as T_{_DL_2}/T_{_UL_2}Time slot, but can configure and seize as T_{_DL_1}Or T_{_UL_1}Time slot.

By said method, preferentially seize T_{_UL_1}And/or T_{_DL_1}Time slot, may be used for T_{_DL_1}Time slot and / or T_{_DL_1}The uplink and downlink sent in time slot control the most various short control information of information and/or reference signal passes Defeated.For ensureing promptness and the reliability that this kind of signal transmits, thus promote systematic function.

Further, in other embodiments, above-mentioned steps S10 may include that

Descending time slot i.e. LTE descending sub frame structure based on configuration, configures unauthorized carrier wave at descending sub frame The control channel domain of structure performs CCA, carries out data transmission at data field.Control territory symbolic number how much may be used With the control territory symbolic number configuration authorizing carrier wave based on described unauthorized carrier wave, to reduce the complexity of configuration Degree.The control territory carrier number such as configured and authorize carrier wave is identical, or fixed phase difference n, n ∈ {1,2,3,4}.Or it is N number of for controlling territory symbolic number described in fixed configurations, N ∈ { 1,2,3,4}.

Further, K subframe, configuration only first in K subframe are taken continuously for configuration The control territory of subframe performs CCA and seizes, if taking successfully, sends data at this K subframe scheduling, if Vacant success, then the time slot after K subframe performs CCA again and seizes；Or it is arranged in described K In individual subframe 1,2 ..., k subframe being seized, if seizing successfully in subframe 1, taking K subframe continuously, If subframe 1 is seized unsuccessful, it tries seize in subframe 2, if seizing successfully, take follow-up continuously K-1 subframe (or taking follow-up K subframe the most continuously), the like.The first preempt-mode above-mentioned Reduce complexity, but it is relatively low to seize probability；The second preempt-mode takies chance and increases, but complexity Higher.

Or, ascending time slot i.e. LTE sub-frame of uplink structure based on configuration, configure unauthorized carrier wave described Last OFDM symbol of sub-frame of uplink structure performs CCA.Further, configuration is accounted for continuously By K subframe, configuration only last OFDM in the previous subframe of first subframe in K subframe Semiology analysis CCA seizes, if taking successfully, sends data at follow-up K subframe scheduling, if vacant Success, then the time slot after K subframe performs CCA again and seizes；Or it is arranged in described K subframe In 1,2 ..., last OFDM symbol of the previous subframe of k subframe is seized, if robbing in subframe 1 Account for and take K subframe the most continuously, if subframe 1 is seized unsuccessful, it tries seize in subframe 2, If seizing successfully, taking follow-up K-1 subframe (or taking follow-up K subframe the most continuously) continuously, depending on Secondary analogize.Above-mentioned first kind of way reduces complexity, but it is relatively low to seize probability；The second way takies Chance increases, but complexity is higher.

Further, in other embodiments, above-mentioned steps S10 may include that

L the subframe that configuration takies continuously, it is descending sub frame that at least a part of which seizes successful first subframe. After first subframe is seized successfully, dynamically indicate the uplink and downlink timeslot configuration information of its follow-up L subframe.Excellent Selection of land, this instruction information is by described first descending sub frame carrying of described unauthorized carrier wave.
