If it should be noted that do not conflict, each feature in the embodiment of the present invention and embodiment can phase Combine mutually, all within protection scope of the present invention.Although in addition, show logical order in flow charts, But in some cases, shown or described step can be performed with the order being different from herein.

Also, it should be noted the embodiment in the embodiment of the present invention is merely to illustrate proposed by the invention non-award The scheduling using method of power frequency.In illustrated embodiment of the present invention, all so that LTE system to use unauthorized frequency As a example by the cell of rate, by disposing low power base station node, (Low Power Node is called for short these cells For LPN) realize, but it is not limiting as the applicable model of the scheduling using method of the unlicensed frequencies that the present invention proposes Farmland, it is possible to understand that, the scheme that the embodiment of the present invention proposes is possible not only to be applicable to LTE system other classes The cell of type, such as macrocell；Can be applicable to use all types of little of other traditional wireless communication technology District, such as UMTS etc..

Unlicensed frequencies need not authorize and just any wireless communication technology can be used freely to make by any focal pointe With therefore relative to authorizing for frequency, when using unlicensed frequencies, it is impossible to guarantee any time, any The all available free unlicensed frequencies resource in place can be used, it is contemplated that this characteristic, the unlicensed frequencies in the present embodiment Scheduling using method be applicable to multicarrier scene, unlicensed frequencies uses as a kind of resource carrier wave, i.e. makees For the second carrier wave or the referred to as auxiliary carrier wave of user equipment (UE), at first carrier or the referred to as main carrier of user equipment On the basis of provide extra frequency resource for user equipment.The present embodiment medium frequency and carrier wave are identical concepts, It is used interchangeably.

In the present embodiment, user equipment has initially set up wireless heterogeneous networks with the first base station in some cell (Radio Resource Control, referred to as RRC) connects, and this cell is controlled by the first base station, this cell The carrier wave being used is the first carrier (main carrier) of user equipment, and this cell is the first little of user equipment District (main plot, Pcell), first carrier is for authorizing frequency.For first carrier, user equipment is using the Establish RRC in the cell of one carrier wave to be connected until user equipment disconnects and the first base station with the first base station Till first carrier changed by RRC connection or user equipment, when there being data transmission to need, user equipment The some or all of Radio Resource on this first carrier can be monopolized with the first base station for transmitting each other Need the data of transmission.When the first base station is according to service needed, the load condition of the first cell, carrier policy Etc. one or more of factor, being determined as user equipment when increasing extra frequency resource, the first base station is passed through First cell is user device configuration the second cell (secondary cell, Scell), and the carrier wave that the second cell uses is the Nd carrier (auxiliary carrier wave), the second carrier wave is unlicensed frequencies.Second cell can be controlled by the first base station, or Person also by the second base station control, or can be controlled by the first base station and the second base station collaboration, the first base station and the By interactive interfacing information between the two between two base stations.

Fig. 7 is a kind of network topology schematic diagram according to this law embodiment, and in the figure 7, M-eNB is grand base Stand, use and authorize frequency F1 to deploy a macrocell cell1.L-eNB1 and L-eNB2 is low power nodes, All support unlicensed frequencies F2, use unlicensed frequencies F2 can realize that cell2, cell3's in figure is little respectively District covers, and L-eNB1, L-eNB2 are all connected with there being interface between M-eNB, such as respectively by Fig. 7 Shown Line1, Line2 realizes being connected with M-eNB.Connect additionally, Fig. 7 is also deployed with two WLAN Access point (Access Point, referred to as AP), AP1 and AP2, both of which support unlicensed frequencies F2, can To use unlicensed frequencies F2 to realize the covering in filled ellipse region, figure midpoint.In Fig. 7, L-eNB1 and AP1 Mutually in the overlay area of the other side, L-eNB1 and AP1 can mutually listen to the other side.Here, mutually supervise Hear the other side, refer to that the radio frequency transmissions of L-eNB1 can be received by the RF Receiving Device of AP1, or Person refers to that the radio frequency transmissions of L-eNB1 can be received and received by the RF Receiving Device of AP1 Signal strength signal intensity/the signal quality of L-eNB1 is better than preset value, and vice versa.

Fig. 8 is another kind of network topology schematic diagram according to embodiments of the present invention, in Fig. 8, L-eNB1 and L-eNB2 is low power nodes, has all both supported to authorize frequency F1, has supported again unlicensed frequencies F2, make respectively With the MPS process authorizing frequency F1 to achieve cell3 and cell1 in figure, unlicensed frequencies F2 is used to achieve The MPS process of cell4 and cell2 in Fig. 8.Equally, Fig. 8 is also deployed with two WLAN AP, AP1 And AP2, both of which supports unlicensed frequencies F2, it is possible to use unlicensed frequencies F2 realizes that figure midpoint is filled ellipse The covering in circle region.In Fig. 8, L-eNB1 and AP1 mutually in the overlay area of the other side, L-eNB1 and AP1 can mutually listen to the other side.

Unlicensed frequencies without authorize just can freely use, therefore in same place, the same time, there may be More than one equipment attempts to use same unlicensed frequencies, and these equipment may use identical or different wireless The communication technology, belongs to the identical or different owner, for ensure unlicensed frequencies among these devices efficient, Fair use, how a lot of countries, area be to using unlicensed frequencies to propose control requirement, such as in Europe, The areas such as Japan, any equipment is wanted to use unlicensed frequencies, it is necessary to perform first to monitor to use (Listen afterwards Before Talk, referred to as LBT) operation, i.e. before initiating data transmission, first pass through clear channel assessment (CCA) (Clear Channel Assessment, referred to as CCA) detects channel busy, i.e. whether detection channel is by it His user uses, and in the case of determining that channel is not used by other users, just carries out data transmission.This In, channel and frequency or carrier wave are identical concepts, are used interchangeably.

As a example by Europe, ETSI (European Telecommunications Standards Institute, referred to as ETSI) just formulate unified use for unlicensed frequencies and required (control requirement), The equipment using unlicensed frequencies needs to perform LBT operation, concrete, performs LBT operation (LBT here Realized by performing CCA) use the equipment of unlicensed frequencies can be divided into following two, hold based on frame structure The equipment (Frame Based Equipment, referred to as FBE) of row LBT and perform LBT's based on load Equipment (Load Based Equipment, referred to as LBE).

FBE monitors with anchor-frame cycle and uses unlicensed frequencies, and equipment is enterprising at a unauthorized channel During row transmission (transmissions), it is necessary to whether first passing through the energy measuring to channel, to assess channel idle (CCA detection), if detecting that on channel energy exceedes the thresholding of regulation, then it is assumed that channel is by it Its hold facility, this equipment is not transmitted in the next anchor-frame cycle on this channel；It otherwise is considered as Channel idle, this equipment can directly be transmitted on this channel.The anchor-frame cycle includes Channel holding time (Channel Occupancy Time) and free time (Idle Period), wherein free time caudal end Part-time is clear channel assessment (CCA) (CCA) time, and the such as CCA time is 20us.Fig. 9 is according to this A kind of time diagram of the FBE of inventive embodiments, as a example by Fig. 9, the anchor-frame cycle 910 includes channel Holding time 911 and free time 912, and the last part time of free time 912 is that idle channel is commented Estimate the time 913.Assume that a device A occupies a unauthorized channel X at Channel holding time 911, at channel After holding time 911 terminates, device A must stop at the transmission on channel X, stops the time of transmission extremely It is free time 912 less.If device A also needs to carry out on channel X after Channel holding time 911 Transmission, then device A is when at least stopping at the CCA before free time 912 end transmitted on channel X Interior carrying out CCA detection to channel X, if testing result is channel idle, then device A is ensuing The transmission of Channel holding time 921 duration can be carried out on channel X, otherwise such as in the anchor-frame cycle 920 Really testing result is that channel is taken by miscellaneous equipment, then in the anchor-frame cycle 920 under connecing for the device A Channel X is not transmitted.The parameters such as concrete Channel holding time and free time are all required by control Concrete regulation.

Being different from FBE, LBE does not triggers with the anchor-frame cycle to monitor and uses unlicensed frequencies, but industry Business or demand trigger to monitor and use unlicensed frequencies, and Figure 10 is the one of LBE according to embodiments of the present invention Plant time diagram, as a example by Figure 10, need at a unauthorized channel when equipment has business or demand to trigger On when being transmitted, it is necessary to first carry out 1010 clear channel assessment (CCA)s or the idle letter of clear channel assessment (CCA)+extension Road is assessed, and whether including equipment first passes through the energy measuring to channel, to assess channel idle (CCA detection), If be detected that the energy on channel is not above the thresholding of regulation, then it is assumed that channel idle, this equipment can be straight It is connected on and be transmitted on this channel；If detecting that on channel energy exceedes the thresholding of regulation, then it is assumed that channel Taken by miscellaneous equipment, equipment proceed on this unauthorized channel extension the free time arrive first detection (Extended CCA, referred to as ECCA), if ECCA detects that energy on channel exceedes the door of regulation Limit, then it is assumed that channel is taken by miscellaneous equipment, and this equipment is not transmitted on this channel, otherwise just recognizes For channel idle, this equipment can directly be transmitted on this channel, and this equipment is transmitted on this channel When a length of 1020 Channel holding times.After 1020 Channel holding times terminate, if equipment wishes to continue to In this unauthorized channel, equipment needs again to perform this unauthorized channel 1030 extension idle channels Assessment, if extension clear channel assessment (CCA) detection channel idle, this equipment just can hold over this unauthorized channel and enter Row transmission, a length of when taking " 1040 Channel holding time ".Wherein, equipment is extended idle channel every time The time span of assessment, such as the 1010th, 1030, can be identical or different, each busy channel of equipment Time span, such as the 1020th, 1040, can be identical or different, concrete time span by equipment according to The correlation formula that control requires is calculated.

With the fast development of Mobile Communication Industry, intelligent terminal occurs on a large scale, and these flood tide intelligent terminals Application varied again, therefore the mobile communication process in future can exist flood tide periodically or burst little Data transfers, transmits these flood tides user's when conventional mobile communications technology needs to expand to unlicensed frequencies During flood tide small data, it is necessary to consider the scheduling using method of unlicensed frequencies with caution, to avoid different operators Interfering when using unlicensed frequencies between conventional mobile communications technology, and avoid conventional mobile communications Use the interference between wireless communication technology in technology and unlicensed frequencies again, and ensure unlicensed frequencies in difference Use efficient, fair between technology, different system, heterogeneous networks.

In view of this, the embodiment of the present invention also proposes the scheduling using method of a kind of unlicensed frequencies.First, The present embodiment makes based on the scheduling of the unlicensed frequencies that three kinds of concrete grammar implementing procedure figure explanation present invention propose Use method.In three kinds of concrete grammar implementing procedure figures, the first cell that user equipment controls in the first base station is (main Cell, Pcell) upper establish RRC with the first base station and be connected, the first base station has been user device configuration second Second cell (secondary cell, Scell) of base station control.Wherein, the first cell uses first carrier, and first carries Ripple is for authorizing frequency, and the second cell uses the second carrier wave, and the second carrier wave is unlicensed frequencies.First base station and Two base stations are identical or different.

Figure 11 is the first method implementing procedure of unlicensed frequencies scheduling using method according to embodiments of the present invention Figure, according to first method implementing procedure figure, unlicensed frequencies scheduling using method includes:

Step S1102, the first base station is UE configuration UE specific semi-persistent scheduling chance；UE receives and protects Deposit the semi-persistent scheduling chance configuration that the first base station sends.

First base station is that the UE specific semi-persistent scheduling chance of UE configuration can include semi-persistent scheduling chance Cycle or semi-persistent scheduling subframe bitmap parameter, can also include that semi-persistent scheduling identifies, and semi-persistent scheduling can make Mixed automatic retransfer (Hybrid Automatic Repeat reQuest, referred to as HARQ) process, from Dynamic deactivation semi-persistent scheduling chance timer or counter, semi-persistent scheduling chance cycle starting point biasing etc. is joined One or more of number.

Wherein, when the first base station and the second base station are different base stations, the first base station is mutual with the second base station After consulting the above-mentioned parameter of semi-persistent scheduling chance again by the first base station be UE configuration described consult alternately half Static scheduling chance configures.Parameter is consulted by interactive interfacing between the two in first base station and the second base station.

UE specific semi-persistent scheduling chance configures, refer to the configuration of this semi-persistent scheduling chance be special configuration to This UE's, the first base station can be respectively configured special half quiet of each UE for each UE accessing this base station State dispatcher can configure.First base station sends semi-static tune to each UE one to one respectively by RRC information Degree chance configuration.

First base station is after UE is configured with semi-persistent scheduling chance, and it is inactive for arranging this semi-persistent scheduling chance State, base station is before activating the configuration of semi-persistent scheduling chance, not in the semi-persistent scheduling chance being configured Each dispatcher can go up with semi-persistent scheduling mark scheduling UE.

Wherein, it is considered to unauthorized carrier wave needs competition to use, and considers further that because variations causes simultaneously The factors such as data re-transmission, in order to ensure the quality of service (Quality of Service, referred to as QoS) of business, First base station is in the semi-persistent scheduling chance configuration of UE configuration, can configure the semi-persistent scheduling chance cycle little In equal to small data business burst measurement period.For FBE, owing to equipment can not be in each anchor-frame cycle Unlicensed frequencies is arrived in competition, equally in order to ensure the QoS of business, can configure the semi-persistent scheduling chance cycle little In equal to the FBE anchor-frame cycle.

Step S1104, the first base station notice UE activates semi-persistent scheduling chance；UE receives the first base station and sends out The semi-persistent scheduling chance activation notification sending.Activation notification includes the downstream assigned information that downlink transfer uses, Or including the uplink authorization information that uplink uses.

Semi-persistent scheduling chance is activated by the access link notice UE between UE and the first cell in first base station, By physical layer down control channel, (Physical Downlink Control Channel is called for short activation notification For PDCCH) carrying.Activation notification includes that (Downlink assignment is called for short downstream assigned information For DL assignment) or uplink authorization information (Uplink grant, referred to as UL grant), DL assignment Or UL grant includes (the Physical Resource of the Physical Resource Block for descending/uplink of distribution Block, referred to as PRB), modulating-coding grade, the resource parameters such as HARQ process.

Wherein, when the first base station and the second base station are different base stations, the first base station and the second base station are assisted alternately After business, the first base station notice UE is activated semi-persistent scheduling chance.

Step S1106, sender is in semi-persistent scheduling chance activationary time, in idle channel detection time inspection Survey the channel status of unlicensed frequencies, if channel idle, then each in ensuing Channel holding time Dispatcher meeting, directly can be in each dispatcher by the resource of downstream assigned in activation notification/uplink authorization instruction Recipient sends data；If channel busy, then not in each dispatcher meeting in ensuing Channel holding time Send data to recipient.

Recipient is in semi-persistent scheduling chance activationary time, in each dispatcher meeting directly in activation notification Data are received in the resource of downstream assigned/uplink authorization instruction；

Or recipient is in semi-persistent scheduling chance activationary time, unauthorized in idle channel detection time detecting The channel status of frequency, if channel idle, then each dispatcher meeting in ensuing Channel holding time, Data are received in the resource that directly downstream assigned/uplink authorization indicates in activation notification, if channel busy, then Notify sender.

Semi-persistent scheduling chance activationary time, refers in step S1104, base station activation semi-persistent scheduling chance Until the time that this semi-persistent scheduling chance is deactivated.Base station can be deactivated by PDCCH notice UE Semi-persistent scheduling chance alive, or, in step S1102, the configuration of semi-persistent scheduling chance comprises automatically to deactivate Live semi-persistent scheduling chance timer or during counter, start when semi-persistent scheduling chance is activated timer or Counter, when the timer times out or at the end of rolling counters forward, it is believed that semi-persistent scheduling chance is deactivated.

In this step, for downlink transfer, sender refers to the second base station, and recipient refers to user equipment (UE)； For uplink, sender refers to user equipment, and recipient refers to the second base station.Particularly, recipient exists When judging channel busy, notifying sender, for downlink transfer, user equipment (recipient) passes through it with first Access link between base station notifies that the first BTS channel does, and is then notified that the second BTS channel does by the first base station (sender).For uplink, the second base station (recipient) first notifies that the first BTS channel does, then First base station is by the access link notifying user equipment channel busy between itself and user equipment (sender).Send out After the side of sending receives the notice of recipient's channel busy, not in each dispatcher meeting in ensuing Channel holding time Send data to recipient.

In this step, sender/recipient is in semi-persistent scheduling chance activationary time, in idle channel detection The channel status of time detecting unlicensed frequencies, for FBE, sender/recipient is in semi-persistent scheduling chance In activationary time, according to the configuration of FBE, at the letter of each idle channel detection time detecting unlicensed frequencies Road state.For LBE, sender, in semi-persistent scheduling chance activationary time, needs transmission when there being data When, (idle channel here detects according to concrete channel status, may refer to initiate idle channel detection CCA, or CCA+ECCA), when being detected as channel idle, then in ensuing Channel holding time Each dispatcher meeting, directly by the resource of downstream assigned in activation notification/uplink authorization instruction in each dispatcher Data can be sent to recipient, after Channel holding time terminates, if sender still has data to transmission, then Sender initiates idle channel detection (this refers to ECCA detection) again.It should be noted that for FBE, FBE relevant parameter, such as anchor-frame cycle, Channel holding time, free time etc., base station and UE are permissible Require to determine according to related control, and mutually notify；Equally, for LBE, Channel holding time is calculated, The clear channel assessment (CCA) time, the relevant parameter of extension clear channel assessment (CCA) time, base station and UE can be according to phases Close control to require to determine, and mutually notify.

In the embodiment of the present invention in first method implementing procedure figure, step S1104 and S1106 implement except above Method, can also be implemented by following another embodiment, comprising:

For downlink transfer, when sender (the second base station) has data to send demand on unlicensed frequencies, The channel status of idle channel detection time detecting unlicensed frequencies, if channel idle, then notifies recipient (UE) activating semi-persistent scheduling chance, by the first base station, sender the second base station notifies that recipient swashs here Semi-persistent scheduling chance alive, sender (the second base station) each scheduling in ensuing Channel holding time Chance, directly can send data to recipient by the resource of downstream assigned instruction in activation notification in each dispatcher. After recipient receives activation notification, each dispatcher meeting in Channel holding time, directly with in activation notification Downstream assigned instruction resource each dispatcher can on receive data；Or after recipient receives activation notification, If before receiving activation notification, passed through idle channel detection to judge channel busy, or logical receiving activation Judge channel busy by idle channel detection after knowing, then notify sender.At the end of this Channel holding time, Sender and recipient think that semi-persistent scheduling chance is deactivated.

For uplink, when sender (UE) has data to send demand on unlicensed frequencies, in the free time The channel status of Channel Detection Time detection unlicensed frequencies, if channel idle, then request recipient (second Base station) activate semi-persistent scheduling chance, sender (UE) is by the first base station requests recipient (the here Two base stations) activate semi-persistent scheduling chance, sender (the second base station) notifies recipient (UE) by the first base station Activate semi-persistent scheduling chance；Or the second base station according to receiving activate request before or after idle channel By the first base station, detection, if channel idle, notifies that sender (UE) activates semi-persistent scheduling chance, Otherwise do not notify that sender (UE) activates semi-persistent scheduling chance.After sender (UE) receives activation notification, Each dispatcher meeting in ensuing Channel holding time, directly with uplink authorization instruction in activation notification Resource each dispatcher can on send data.Recipient (the second base station) is directly awarded by up in activation notification Power instruction resource each dispatcher can on receive data.At the end of this Channel holding time, sender and Recipient thinks that semi-persistent scheduling chance is deactivated.

Use the unlicensed frequencies scheduling using method of above-mentioned first method implementing procedure figure, it is possible to achieve non- Authorize in frequency noiseless, efficiently, fair transmission flood tide small data, and can effectively reduce flood tide decimal According to the mandate frequency that causes of transmission on the expense of PDCCH scheduling.

Figure 12 is the second method implementing procedure of unlicensed frequencies scheduling using method according to embodiments of the present invention Figure, according to second method implementing procedure figure, the method that unlicensed frequencies scheduling uses includes:

Step S1202, the first base station is all UE configuration public semi-static of cell residing in the first cell Dispatcher meeting；The UE residing in the first cell receives and preserves the semi-persistent scheduling chance that the first base station sends.

First base station is that the public semi-persistent scheduling chance of cell of all UE configuration residing in the first cell can To include semi-persistent scheduling chance cycle or semi-persistent scheduling subframe bitmap parameter, semi-persistent scheduling can also be included Spendable HARQ process, deactivates in the parameter such as semi-persistent scheduling chance timer or counter automatically One or all, the scheduling mark monitoring the public semi-persistent scheduling notice in activation cell for UE can also be included Knowing, i.e. activating scheduling identification, certainly, this activates scheduling identification and also can provide according to consensus standard Scheduling identification.

Wherein, when the first base station and the second base station are different base stations, the first base station is mutual with the second base station Consult semi-persistent scheduling chance above-mentioned parameter after again by first base station configuration described consult alternately semi-static Dispatcher can configure.Parameter is consulted by interactive interfacing between the two in first base station and the second base station.

The public semi-persistent scheduling chance of cell, refers to that the configuration of this semi-persistent scheduling chance is resident to this cell All UE can use.RRC information, such as broadcast cell can be passed through in first base station Public semi-persistent scheduling chance；Or the first base station can be by being sent to the RRC of each UE one to one Specific messages notifies the public semi-persistent scheduling chance of each UE cell.

After each UE accesses the first base station, the first base station is each UE configuration semi-persistent scheduling mark, respectively The semi-persistent scheduling mark of individual UE is different.

Wherein, it is considered to unauthorized carrier wave needs competition to use, and considers further that because variations causes simultaneously The factors such as data re-transmission, in order to ensure the QoS of business, the public semi-persistent scheduling machine of the first base station configuration cell During meeting, the semi-persistent scheduling chance cycle can be configured less than or equal to various small data business burst measurement periods.Right In FBE, owing to equipment can not compete unlicensed frequencies in each anchor-frame cycle, equally in order to ensure industry The QoS of business, can configure the semi-persistent scheduling chance cycle less than or equal to the FBE anchor-frame cycle.

Step S1204, the first base station notifies that one or more UE activates semi-persistent scheduling chance；This or Multiple UE receive the semi-persistent scheduling chance activation notification that the first base station sends.Activation notification include one or The semi-persistent scheduling mark of multiple UE, this activation notification can also include be respectively allocated to a UE or The downstream assigned information that in multiple UE, each UE downlink transfer uses, or include being respectively allocated to one The uplink authorization information that in UE or multiple UE, each UE uplink uses.

First base station is according to the service conditions of each UE, it is judged that have one or more UE to need to use half quiet When state dispatcher can transmit data, notify one or more by the access link between UE and the first cell UE activates semi-persistent scheduling chance.Activation notification is carried by PDCCH, when activating a UE, activates Notice includes that the semi-persistent scheduling of this UE identifies and distributes to the semi-persistent scheduling machine of this UE The DL assignment that can use or UL grant.When activating multiple UE, activation notification includes this The semi-persistent scheduling of multiple UE identifies and is respectively allocated to the semi-persistent scheduling chance use of the plurality of UE DL assignment or UL grant.

Access each UE of the first base station and can go with activation scheduling identification that the PDCCH of the first base station is public to be searched The activation notification that the first base station sends is monitored in rope space.In activation notification, the semi-persistent scheduling mark of UE indicates One or more UE, after receiving activation notification, activate semi-persistent scheduling configuration.

Step S1206, sender is in semi-persistent scheduling chance activationary time, in idle channel detection time inspection Survey the channel status of unlicensed frequencies, if channel idle, then each in ensuing Channel holding time Dispatcher meeting, directly can be in each dispatcher by the resource of downstream assigned in activation notification/uplink authorization instruction Recipient sends data；If channel busy, then not in each dispatcher meeting in ensuing Channel holding time Send data to recipient.

In this step, for downlink transfer, sender refers to the second base station, and recipient refers to step S1204 One or more of UE.Second base station is in semi-persistent scheduling chance activationary time, in idle channel detection The channel status of time detecting unlicensed frequencies, if channel idle, then in ensuing Channel holding time Each dispatcher meeting, directly with activation notification is distributed to one or more UE downstream assigned indicate money Source can send data to one or more UE in each dispatcher；If channel busy, then at ensuing channel Data can not sent to one or more UE in each dispatcher in holding time.One or more UE are half In static scheduling chance activationary time, in each dispatcher meeting, directly in activation notification, distribute to a UE Or receive data in the resource of the downstream assigned instruction of multiple UE；Or one or more UE are at semi-static tune In degree chance activationary time, at the channel status of idle channel detection time detecting unlicensed frequencies, if channel Free time, then each dispatcher meeting in ensuing Channel holding time, directly distributes in activation notification One or more UE downstream assigned instruction resource each dispatcher can on receive data, if channel busy, One or more UE (recipient) notify the first BTS channel by the access link between itself and the first base station Busy, then the first base station is notified that the second BTS channel does (sender).Second base station receives recipient's channel After busy notice, in ensuing Channel holding time, data can not sent to recipient in each dispatcher.

In this step, for uplink, sender refers to one or more of step S1204 UE, connects Debit refers to the second base station.One or more UE are in semi-persistent scheduling chance activationary time, at idle channel The channel status of detection time detecting unlicensed frequencies, if channel idle, then when ensuing channel occupancy Each interior dispatcher meeting, is directly indicated by the uplink authorization distributing to one or more UE in activation notification Resource each dispatcher can to second base station send data；If channel busy, then account at ensuing channel Data can not sent in each dispatcher to the second base station within the time.Second base station is swashed in semi-persistent scheduling chance In live time, in each dispatcher meeting, directly in activation notification, distribute to the up of one or more UE award Data are received in the resource of power instruction；Or, the second base station is in semi-persistent scheduling chance activationary time, at sky The channel status of idle channel detection time detecting unlicensed frequencies, if channel idle, then at ensuing channel Each dispatcher meeting in holding time, directly distributes to the up of one or more UE in activation notification and awards The resource of power instruction each dispatcher can on receive data, if channel busy, the second base station (recipient) first Notifying that the first BTS channel does, then the first base station is by between itself and one or more UE (sender) Access link notifies one or more UE channel busy.One or more UE receive the notice of recipient's channel busy After, in ensuing Channel holding time, data can not sent to recipient in each dispatcher.

The definition of semi-persistent scheduling chance activationary time in this step, sender/recipient is at semi-persistent scheduling machine In meeting activationary time, in the explanation of the channel status of idle channel detection time detecting unlicensed frequencies, same to step S1106.If no special instructions, follow-up specification herewith illustrates.

In second method implementing procedure figure in the embodiment of the present invention, step S1204 and S1206, except more than Outside implementation, it would however also be possible to employ the another kind of implementation described in first method implementing procedure is implemented, right In uplink, with the description of replacement step S1104 and the technical characteristic of S1106, and for downlink transfer, When sender (the second base station) oriented one or more UE on unlicensed frequencies send the demand of data, The channel status of idle channel detection time detecting unlicensed frequencies, if channel idle, then notifies recipient ( Individual or multiple) activate semi-persistent scheduling chance, sender the second base station notifies recipient by the first base station here Activating semi-persistent scheduling chance, activation notification includes each of respectively one UE or multiple UE distribution The downstream assigned information that UE downlink transfer uses, and the semi-persistent scheduling mark of one or more UE. Sender (the second base station) each dispatcher meeting in ensuing Channel holding time, directly logical with activating The resource of the downstream assigned instruction distributing to one or more UE in knowing can send to recipient in each dispatcher Data.

Access each UE of the first base station and can go with activation scheduling identification that the PDCCH of the first base station is public to be searched The activation notification that the first base station sends is monitored in rope space.In activation notification, the semi-persistent scheduling mark of UE indicates One or more UE, after receiving activation notification, activate semi-persistent scheduling configuration.Recipient is (one or more UE), after receiving activation notification, each dispatcher meeting in Channel holding time, directly with in activation notification Distribute to one or more UE downstream assigned instruction resource each dispatcher can on receive data；Or After recipient (one or more UE) receives activation notification, if passed through before receiving activation notification Idle channel detection judges channel busy, or judges channel by idle channel detection after receiving activation notification Busy, then notify sender.At the end of this Channel holding time, sender and recipient think semi-persistent scheduling Chance is deactivated.

Use the unlicensed frequencies scheduling using method of second method implementing procedure figure in the embodiment of the present invention, permissible Realize noiseless on unlicensed frequencies, efficiently, fair transmission flood tide small data, and pass through PDCCH The activation notification of carrying disposably activates one or more UE having data transfer demands, can be in first method Implementing procedure technical, effectively reduces in the mandate frequency that the transmission of flood tide small data causes further The expense of PDCCH scheduling.

Figure 13 is the third method implementing procedure of unlicensed frequencies scheduling using method according to embodiments of the present invention Figure, third method implementing procedure figure is applicable to the downlink data transmission to UE transmission data for the base station.According to the 3rd Method implementing procedure figure, unlicensed frequencies scheduling using method includes:

Step S1302, the first base station is all UE configuration public semi-static of cell residing in the first cell Dispatcher meeting；The UE residing in the first cell receives and preserves the semi-persistent scheduling chance that the first base station sends.

This step specific explanations is with step S1202.

Step S1304, the second base station needs when one or more UE send data transmission, and the first base station leads to Know that one or more UE activates semi-persistent scheduling chance；One or more UE receive half that the first base station sends Static scheduling chance activation notification.Activation notification includes one or more downstream assigned letter that downlink transfer uses Breath.

First base station is according to the service conditions of each UE, it is judged that need to use semi-persistent scheduling chance to one or During person multiple UE transmission data, notify one or more by the access link between UE and the first cell UE activates semi-persistent scheduling chance.Activation notification is carried by PDCCH, activation notification comprises this or The semi-persistent scheduling mark of multiple UE and one or more downstream assigned information.

Step S1306, sender (the second base station) is in semi-persistent scheduling chance activationary time, at free time letter The channel status of road detection time detecting unlicensed frequencies, if channel idle, then at ensuing channel occupancy Each dispatcher meeting in time, directly by the resource of one or more downstream assigned instruction in activation notification respectively Individual dispatcher can send data to one or more UE；If channel busy, then when ensuing channel occupancy Interior each dispatcher can to one or more UE send data.

Recipient (one or more UE) is in semi-persistent scheduling chance activationary time, in each dispatcher meeting Directly receive data in the resource of each downstream assigned in activation notification；Or recipient is at semi-persistent scheduling In chance activationary time, at the channel status of idle channel detection time detecting unlicensed frequencies, if channel is empty Spare time, then each dispatcher meeting in ensuing Channel holding time, directly under each in activation notification Row assign instruction resource on receive data, if channel busy, then notify sender (first notify the first base station, Again the first base station is notified the second base station).

Here, if a dispatcher meeting, the second base station needs to send data, then the second base to multiple UE Stand and send data to multiple UE respectively by the resource of downstream assigned instructions different in multiple downstream assigned respectively. Here, can go up in different dispatcher, can be by the resource of instruction in different downstream assigned to same UE Send data.

Here one or more UE are in semi-persistent scheduling chance activationary time, can directly exist in each dispatcher Data are received, if received data is destined to this in the resource of each downstream assigned in activation notification The data of UE are then processed, and otherwise abandon.Concrete, UE can be judged whether by the scrambling mode of data It is destined to the data of oneself.

Or,

Sender (the second base station) is in semi-persistent scheduling chance activationary time, in idle channel detection time inspection Survey the channel status of unlicensed frequencies, if channel idle, then each in ensuing Channel holding time Dispatcher meeting, with one of scheduling control information instruction activation notification of the PDCCH of the first base station carrying or Multiple downstream assigned use relation corresponding with one or more UE, and directly use pass to tie up to down according to correspondence Row is assigned and is sent data to corresponding UE in the resource of instruction；If channel busy, then account at ensuing channel Data can not sent in each dispatcher to one or more UE within the time.

Recipient (one or more UE) receives PDCCH scheduling control information, if PDCCH control The UE that information processed instruction receives this information uses one of them downstream assigned, then UE is directly descending at one Assign and in the resource of instruction, receive data.Or, recipient (one or more UE) is at semi-persistent scheduling machine In meeting activationary time, at the channel status of idle channel detection time detecting unlicensed frequencies, if channel idle, One or more UE receive PDCCH scheduling control information, if the instruction of PDCCH control information receives The UE of this information uses one of them downstream assigned, then UE is directly in the resource of a downstream assigned instruction Upper reception data.If channel busy, one or more UE notify sender (first notify the first base station, then by First base station notifies the second base station).

Here, if a dispatcher meeting, the second base station needs to send data, then the second base to multiple UE Stand with the multiple UE of PDCCH scheduling control information instruction uses which downstream assigned in activation notification respectively. Here, can go up in different dispatcher, different downstream assigned can be indicated with PDCCH scheduling control information Send data to same UE.

In third method implementing procedure figure of the present invention, step S1304 and S1306, in addition to above implementation, Also the another kind of implementation described in similar second method implementing procedure can be used to replace.Concrete second When base station oriented one or more UE on unlicensed frequencies send the demand of data, when idle channel detects Between the channel status of detection unlicensed frequencies, if channel idle, then notify that one or more UE activates half quiet State dispatcher meeting, by the first base station, the second base station notifies that one or more UE activates semi-persistent scheduling machine here Meeting, comprises one or more downstream assigned information in activation notification, and one or more UE's is semi-static Scheduling identification.Each dispatcher meeting in ensuing Channel holding time of second base station, directly logical with activating The resource of one or more downstream assigned instruction in knowing can send data to one or more UE in each dispatcher.

Access each UE of the first base station and can go with activation scheduling identification that the PDCCH of the first base station is public to be searched The activation notification that the first base station sends is monitored in rope space.In activation notification, the semi-persistent scheduling mark of UE indicates One or more UE, after receiving activation notification, activate semi-persistent scheduling configuration.One or more UE receive After activation notification, each dispatcher meeting in Channel holding time, directly one or more in activation notification Data are received in the resource of downstream assigned instruction；Or after one or more UE receive activation notification, if Pass through idle channel detection before receiving activation notification and judge channel busy, or after receiving activation notification Judge channel busy by idle channel detection, then notify sender.At the end of this Channel holding time, send Side and recipient think that semi-persistent scheduling chance is deactivated.

Or, above-mentioned replacement step also can be, the second base station is oriented one or more on unlicensed frequencies When UE sends the demand of data, at the channel status of idle channel detection time detecting unlicensed frequencies, if Channel idle, then notify that one or more UE activates semi-persistent scheduling chance, and the second base station passes through first here Base station notifies that one or more UE activates semi-persistent scheduling chance, comprises one or more descending in activation notification Assignment information, and the semi-persistent scheduling mark of one or more UE.Second base station is at ensuing channel Each dispatcher meeting in holding time, is swashed by the scheduling control information instruction of the PDCCH carrying of the first base station One or more of notice of living downstream assigned use relation corresponding with one or more UE, and direct basis Corresponding use is closed in the resource tying up to downstream assigned instruction to corresponding UE transmission data.

Access each UE of the first base station and can go with activation scheduling identification that the PDCCH of the first base station is public to be searched The activation notification that the first base station sends is monitored in rope space.In activation notification, the semi-persistent scheduling mark of UE indicates One or more UE, after receiving activation notification, activate semi-persistent scheduling configuration.One or more UE receive After activation notification, each dispatcher meeting in Channel holding time, if receiving PDCCH control information And the UE of this control information instruction this information of reception uses one of them downstream assigned, then UE is directly one Data are received in the resource of individual downstream assigned instruction.Or after one or more UE receive activation notification, if Passed through idle channel detection before receiving activation notification, judged channel busy, or receive activation notification it Judge channel busy by idle channel detection afterwards, then notify sender.At the end of this Channel holding time, send out The side of sending and recipient think that semi-persistent scheduling chance is deactivated.

Use the unlicensed frequencies scheduling using method of third method implementing procedure figure of the present invention, it is possible to achieve non- Authorize in frequency noiseless, efficiently, fair transmission flood tide small data, and by swashing that PDCCH carries Notice of living is disposable activates one or more UE having data transfer demands, can be at first method implementing procedure Technical, reduce further effectively what PDCCH in the mandates frequency that the transmission of flood tide small data causes dispatched Expense.Meanwhile, in the 3rd implementation, the resource of a downstream assigned can be by different UE not Same dispatcher can go up shares use, can improve again the service efficiency of resource further.

According to above-mentioned specific implementation method, illustrate the unauthorized frequency of the present invention below in conjunction with drawings and Examples Rate dispatches using method.

Embodiment one

Figure 14 is the scheduling using method flow chart of the unauthorized carrier wave of according to embodiments of the present invention, embodiment One uses UE1 under its coverage for the unlicensed frequencies F2 with L-eNB1 in accompanying drawing 7, under UE2 transmission Row data instance, what first method of the present invention was described is embodied as example.In the present embodiment, all of UE is Possess multi-carrier capability, including following implementation process:

Step S1402, UE1, UE2 set up RRC with M-eNB on the cell1 that M-eNB controls and are connected.

UE1 and UE2 and M-eNB set up after RRC is connected access M-eNB, and M-eNB is according to business Need, the load condition of cell1, one or more of factor such as carrier policy, such as UE1 and UE2 Business transmission demand improve, M-eNB be UE1 and UE2 configuration cell2, now cell1 be UE1 and The main plot of UE2, cell2 is the secondary cell of UE1 and UE2, and cell2 uses unlicensed frequencies F2.

Step S1404, M-eNB sends to UE1 and UE2 and is respectively descending the half of UE1 and UE2 configuration Static scheduling chance configures.

M-eNB is by the access link between UE1 and UE2, by RRC specific messages, such as RRC Reconfiguration message (RRCConnectionReconfiguration) sends configuration to UE1 and UE2 respectively.

Figure 15 is that M-eNB is the semi-persistent scheduling machine of UE1 and UE2 configuration in one according to embodiments of the present invention Can configuration schematic diagram.In the present embodiment, cell2 and UE1, UE2 use unlicensed frequencies F2 when, based on FBE performs LBT, and the frame sequential of FBE is as shown in Figure 15.In the present embodiment, M-eNB is UE1/UE2 The semi-persistent scheduling chance configuration of configuration configures in a periodic fashion, and configuration includes the semi-persistent scheduling chance cycle, Semi-persistent scheduling chance cycle starting point biases, the semi-persistent scheduling mark of UE1/UE2.M-eNB is at Figure 15 The middle T1 moment sends above-mentioned configuration to UE1/UE2.In the present embodiment, M-eNB is UE1, and UE2 configures It in the semi-persistent scheduling chance cycle of identical point length, is configured with different semi-persistent scheduling chance cycle starting points Biasing.In the present embodiment, the semi-persistent scheduling chance cycle of configuration is equal to the FBE frame period, in actual application, The frame period that the semi-persistent scheduling chance cycle is not equal to FBE, such as configuration semi-persistent scheduling can be configured completely The frame period less than FBE for the chance cycle.

It should be noted that M-eNB is before UE sends semi-persistent scheduling configuration, if L-eNB1 has independence In the radio resource control unit of M-eN, M-eNB needs the connection between by M-eNB and L-eNB1 Line1, consults to be allocated to the semi-persistent scheduling configuration parameter of UE, i.e. 1404-1 institute in Figure 14 with L-eNB1 Show.

UE1 and UE2 receives and preserves semi-persistent scheduling configuration, in this step, after receiving configuration, UE1 Can be according to semi-persistent scheduling chance cycle (being designated as: CYCLE) and semi-persistent scheduling chance cycle with UE2 Starting point biasing (being designated as: CYCLE-OFFSET) is calculated the moment of all semi-persistent scheduling chances, As shown in black round dot in figure, concrete computational methods can be [SFN*10+SUBFRAME] %CYCLE=CYCLE-OFFSET%CYCLE, SFN is system here Frame number, SUBFRAM is subframe numbers, and % represents modulo operation, calculated SFN and SUBFRAME It is the moment of semi-persistent scheduling chance.In this step, if it is quiet not configure half in the configuration of semi-persistent scheduling chance State dispatcher can cycle starting point bias, then UE1 and UE2 receives and preserve semi-persistent scheduling configuration, after waiting After continued access receives activation semi-persistent scheduling chance configuration order, then calculate the moment of each semi-persistent scheduling chance.

Step S1406, M-eNB notifies UE1, and UE2 activates the configuration of semi-persistent scheduling chance.

M-eNB needs by L-eNB1 to UE1, and when UE2 sends data, M-eNB uses M-eNB With UE1, the access link between UE2, use activation notification the notice UE1, UE2 being carried by PDCCH Activate semi-persistent scheduling chance configuration (T2 moment in Figure 15).Activation notification can be to use UE1, UE2 Cell1 is respectively allocated Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (the Cell Radio Network obtaining Temporary Identifier, C-RNTI) scramble represents the PDCCH that activation semi-persistent scheduling chance configures The signaling of upper transmission, it is also possible to be used in step S1404 the UE1 of distribution, the semi-persistent scheduling of UE2 Representing of mark scrambling activates the signaling sending on the PDCCH that semi-persistent scheduling chance configures.

Comprise in activation notification that M-eNB distributed sends downlink data for L-eNB1 to UE1, UE2 DL assignment。

If step S1404, the configuration of semi-persistent scheduling chance does not configures semi-persistent scheduling chance cycle starting point Biasing, then in this step, after UE1, UE2 receive activation notification, according to semi-persistent scheduling chance cycle (note For: CYCLE) and when receiving activation notification frame number (being designated as: SFN-a) and subframe numbers (be designated as: SUBFRAME-a), being calculated the moment of each semi-persistent scheduling chance, computational methods can be SFN*10+SUBFRAME=[(10*SFN-a+SUBFRAME-a)+N*CYCLE] %10240, here SFN is System Frame Number, and SUBFRAM is subframe numbers, and % represents modulo operation, the integer more than 0 for the N, meter SFN and SUBFRAME obtaining is the moment of semi-persistent scheduling chance, such as shade round dot in Figure 15 Shown in.

It should be noted that the computational methods of another kind of semi-persistent scheduling chance, the present embodiment are merely just described In subsequent step, all explanations as a example by the semi-persistent scheduling chance that step S1404 is calculated.

It should be noted that M-eNB is before UE sends activation notification, if L-eNB1 has independent of M-eN Radio resource control unit, then M-eNB needs the connection Line1 between by M-eNB and L-eNB1, Consult to send the opportunity of activation notification with L-eNB1, in Figure 14 shown in step S1406-1.

Step S1408, CCA detects；

The CCA detection time (figure of first free time after M-eNB sends activation notification for the L-eNB1 15CCA1) CCA detection is carried out to F2, F2 channel idle detected.

Optionally, when the CCA of first free time after receiving activation notification for UE1 and UE2 detects Between (Figure 15 CCA1) CCA detection is carried out to F2.In the present embodiment, it is assumed that the AP1 near UE1 this When taking F2, therefore UE1 detects channel busy, and UE2 is because away from AP1, letter therefore detected Road is idle.

Step S1410, UE1 notifies M-eNB channel busy.

UE1 is by the access link notice M-eNB channel busy between itself and M-eNB1.M-eNB receives After the notice of channel busy, if L-eNB1 has the radio resource control unit independent of M-eN, then M-eNB Need the connection Line1 between by M-eNB and L-eNB1, notify L-eNB1 channel busy.

Step S1412, L-eNB1 sends data in the T3 moment to UE2；

The resource that L-eNB1 directly utilizes the downstream assigned instruction distributing to UE2 in activation notification is sent out to UE2 Send data, the semi-persistent scheduling mark scrambling of data UE2.In the present embodiment configuration, semi-persistent scheduling machine Cycle can be equal to FBE frame period, therefore only one of which semi-persistent scheduling chance in a Channel holding time, If having multiple semi-persistent scheduling chance in Channel holding time of configuration in actual application, then L-eNB1 is at this All direct activation notification is repeatedly distributed in semi-persistent scheduling chance the resource of the downstream assigned instruction of UE2 Send data to UE2.

Step S1414, CCA detects；

The CCA detection time F2 of second free time after M-eNB sends activation notification for the L-eNB1 Carry out CCA detection (Figure 15 CCA2), F2 channel idle detected.

Optionally, when the CCA of first free time after receiving activation notification for UE1 and UE2 detects Between F2 carry out CCA detection (Figure 15 CCA2), channel idle all detected.

Step S1416, L-eNB1 sends data in the T4/T5 moment to UE1/UE2；

L-eNB1 directly utilize activation notification is distributed to UE1/UE2 downstream assigned instruction resource to UE1/UE2 sends data, the semi-persistent scheduling mark scrambling of data UE1/UE2.

Step S1418, M-eNB notifies UE1, and UE2 deactivates the configuration of semi-persistent scheduling chance.

M-eNB judges to be no longer necessary to by L-eNB1 to UE1, and when UE2 sends data, M-eNB uses Access link between M-eNB and UE1, UE2, uses the deactivation notice notice being carried by PDCCH UE1, UE2 deactivate semi-persistent scheduling chance configuration (T6 moment in Figure 15).Deactivating notice can be Using UE1, UE2 is respectively allocated Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (the Cell Radio obtaining on cell1 Network Temporary Identifier, C-RNTI) expression that scrambles deactivates the configuration of semi-persistent scheduling chance PDCCH on the signaling that sends, it is also possible to be used in step S1404 the UE1 of distribution, the half of UE2 Representing of static scheduling mark scrambling deactivates the signaling sending on the PDCCH that semi-persistent scheduling chance configures.

It should be noted that M-eNB to UE send deactivate notice before, if L-eNB1 have independent of The radio resource control unit of M-eN, then M-eNB needs the connection between by M-eNB and L-eNB1 Line1, notice L-eNB1 semi-persistent scheduling chance configuration is deactivated, in Figure 14 shown in step S1418-1.

Embodiment two
