Hereinafter, will the uplink scheduling side in the communication network of authorized frequency bands and unlicensed band is supported be described
Method.Here, uplink subframe can include PUSCH.For example, it can be wrapped by the uplink subframe of uplink license scheduling
Include PUSCH.Uplink license can be classified as single uplink license and the license of more uplinks.Single uplink license
Can be for dispatching the license of the uplink of single uplink subframe (for example, PUSCH).More uplinks are permitted
For dispatching the license of the uplink of multiple uplink subframes (for example, PUSCH).
Dispatching method based on the license of single uplink can be as follows.
Figure 13 is the sequence chart of the first embodiment for the method for showing to send for scheduling uplink in a communication network,
And Figure 14 is the concept map of the first embodiment for the subframe for showing scheduling in a communication network.
With reference to Figure 13 and 14, base station can be the base station shown in Fig. 1 to Fig. 4, and terminal may be coupled to base station.Base
Standing can support cellular communication (for example, LTE, LTE-A, LAA, eLAA for defining in the 3 gpp standards with each in terminal
Deng) and operated in unlicensed band and authorized frequency bands.Also, each in base station and terminal can be with showing in Fig. 5
Communication node 500 it is same or similar.
Single uplink license (S1300) can be configured in base station.For example, when receiving request uplink scheduling from terminal
Message when, the license of single uplink can be configured in base station.Single uplink license can be included in the parameter described in table 4
It is at least one.Also, single uplink license can also include parameter and the parameter described in table 4.
[table 4]
Base station can send the down link control information (DCI) (S1310) permitted including single uplink.It can pass through
At least one of PDCCH and enhanced PDCCH (EPDCCH) send DCI.DCI including the license of single uplink can lead to
Subframe #n is crossed to send, and single uplink license can be with the transmission of scheduling subframe # (n+l).N can be equal to or greater than zero
Integer.L can be preset in base station and terminal.It base station can be by higher level signaling (for example, RRC signaling) to terminal notification
1.L can be equal to or greater than 4 integer.For example, the single uplink license sent by subframe #0 can be with scheduling subframe #4
Transmission, and sent by subframe #1 single uplink license can be with the transmission of scheduling subframe #5.
Terminal can obtain DCI, and can identify and be included in by monitoring (or detection) PDCCH and EPDCCH
Single uplink license (S1320) in DCI.Terminal can be identified based on the parameter in single uplink license is included in
The transmission of subframe # (n+l) is scheduled, and subframe # (n+ are configured based on being included in the parameter in the license of single uplink
l).Subframe # (n+l) can be sent to base station (S1330) by terminal.For example, terminal can will be by being received by subframe #0
The subframe #4 of single uplink license scheduling is sent to base station, and will be permitted by the single uplink received by subframe #1
The subframe #5 of scheduling is sent to base station.
Base station can be based on being included in single uplink license (for example, being permitted via the subframe #n single uplinks sent
Can) in parameter from terminal receive subframe # (n+l).For example, base station can be based on being included on the list sent by subframe #0
Parameter in line link license receives subframe #4 from terminal, and can be based on being included in single uplink for being sent by subframe #1
Parameter in link license receives subframe #5 from terminal.
Meanwhile pre-setting the sending time of uplink license and the uplink by uplink license scheduling
In the case of interval between the sending time of subframe, the transmission of uplink license can be in preset interval with one-to-one
Mode and the transmission of uplink subframe match.When using from carrier wave scheduling scheme, uplink license transmission and
It can be by same carrier wave (that is, identical in TDD communication networks by the transmission of the uplink subframe of uplink license scheduling
Carrier wave) or pairs of carrier wave (that is, a pair of of carrier wave in FDD communication networks) perform.When using cross-carrier scheduling scheme,
The carrier wave of uplink license is sent by it and can be different from the uplink dispatched by its transmission by uplink license
The carrier wave of subframe.Cross-carrier scheduling scheme can be used in the communication network for supporting carrier aggregation.
In the FDD communication networks for supporting authorized frequency bands, due to downlink carrier and uplink carrier separate configuration,
So the transmission of uplink license can match with the transmission of uplink subframe in a manner of one-to-one.Also, it is propping up
It holds in the TDD communication networks of authorized frequency bands, has pre-defined " UL-DL sub-frame configurations " due to being based on table 1, uplink is permitted
Can transmission can match in a manner of one-to-one with the transmission of uplink subframe.
On the other hand, in the communication network for supporting unlicensed band, due to channel use it is uncertain, variable upper
Line link-downlink subframe configurations etc., sending for uplink license can be with the uplink by uplink license scheduling
The transmission of way frame dynamically matches.When use is from carrier wave scheduling scheme in the communication network for supporting unlicensed band,
Variable uplink-downlink sub-frame configuration may be difficult.For example, if the quantity of downlink subframe is less than packet
Include the quantity of the uplink subframe in the subframe burst (or radio frames) of multiple subframes, then it may the conventional uplink of limitation
The use of dispatching method.
Next, by the dispatching method permitted based on more uplinks is described.Can be based on from carrier wave scheduling scheme or
Cross-carrier scheduling scheme performs following dispatching method.

A uplink subframe, three downlink subframes and a special subframe.Base station can be generated for scheduling uplink
More uplinks license of frame #4 to #6, and permitted by subframe #0 to send more uplinks of generation.
Meanwhile in multiple uplink subframes by the license scheduling of more uplinks, the first uplink in time domain
Subframe can be referred to as " starting uplink subframe ".For example, uplink subframe #4 can start uplink subframe.
In multiple uplink subframes by the license scheduling of more uplinks, the last one uplink subframe in time domain can be claimed
For " terminating uplink subframe ".For example, uplink subframe #6 can terminate uplink subframe.
More uplink licenses can be classified as " more uplink license types 1 " and " more uplink license types
2”。
1) more uplink license types 1
It, can be with each in the multiple uplink subframes of configuration schedules when using more uplink license types 1
More uplink licenses.For example, may be configured to more uplinks license A of scheduling uplink subframe #4, can be configured
More uplinks for scheduling uplink subframe #5 permit B and may be configured to scheduling uplink subframe #6's
More uplinks permit C.In this case, each in more uplink license A, B and C can be included in different
In DCI.For example, more uplinks license A can be included in the first DCI, more uplinks license B can be included in the
In two DCI, and more uplinks license C can be included in the 3rd DCI.Also, in more uplink license A, B and C
Each can be scrambled (), and by identical based on identical radio network temporary identifier (RNTI)
Subframe #0 is sent.
2) more uplink license types 2
It, can be with more uplinks of the multiple uplink subframes of configuration schedules when using more uplink license types 2
License.More uplink licenses can include a public field and multiple independent fields.For example, the license of more uplinks can be with
Including being used for the public field of uplink subframe #4 to #6, for the independent field A of uplink subframe #4, for uplink
The independent field B of the way frame #5 and independent field C for uplink subframe #6.
Public field can be included at least one parameter being used in conjunction in multiple uplink subframes.It is for example, public
Field can include the resource block assignment information for uplink subframe #4 to #6, MCS, transmission power control (TPC) order
Deng.Independent field can be configured for each in multiple uplink subframes and can be including for multiple uplinks
The different parameters of each in way frame.For example, individually each in field A, B and C can include HARQ process numbers,
RV, NDI etc..
Dispatching method based on above-mentioned subframe structure (for example, subframe structure shown in Figure 15) can be as follows.
Figure 16 is the sequence chart of the second embodiment for the method for showing to send for scheduling uplink in a communication network.
With reference to figure 16, base station can be the base station shown in Fig. 1 to 4, and terminal may be coupled to base station.Base station and end
Each in end can support cellular communication (for example, LTE, LTE-A, LAA, eLAA for defining in the 3 gpp standards etc.) and
It is operated in unlicensed band and authorized frequency bands.Also, each in base station and terminal can be with the communication section that is shown in Fig. 5
Point 500 is same or similar.
Base station can be permitted to terminal notification more by higher level signaling (for example, RRC signaling) by more uplinks
The scheduling (S1600) of the transmission of a uplink subframe.Under specific circumstances (for example, the quantity when uplink subframe is more than
During the quantity of downlink subframe), the scheduling that the uplink based on the license of more uplinks is sent may be necessary, and
Therefore such case can be directed to and perform step S1600.
Also, base station can be by higher level signaling (for example, RRC signaling) to the more uplink license types of terminal notification
(for example, Class1 or type 2) can be permitted maximum quantity of uplink subframe of scheduling etc. by more uplinks.It can be by
The maximum quantity of the uplink subframe of more uplink license scheduling can be referred to as " MSF”。MSFIt may be greater than or be equal to
Zero integer.For example, MSFCan be 4.
Terminal can identify that the transmission of multiple uplink subframes is by more by higher level signaling (for example, RRC signaling)
Uplink permits to dispatch.In this case, terminal can activate the more uplinks for dispatching multiple uplink subframes
The receive capabilities of road license.Also, terminal can identify that more uplinks are permitted by higher level signaling (for example, RRC signaling)
Type (for example, Class1 or type 2), MSFDeng.
Meanwhile if uplink is required to send, terminal can send request scheduling to the uplink of base station to base station
The message (S1610) that road is sent.It is supported mostly for asking the message of scheduling that uplink is sent that can include instruction terminal
The indicator of line link license, more uplink license types etc..When the scheduling sent from terminal request uplink, base station
Can (S1620) be permitted with collocating uplink link.In the case where terminal supports more uplink licenses, base station may be configured to
Dispatch more uplinks license of multiple uplink subframes.Also, base station can determine the type of more uplink licenses.
In this case, base station can determine the type that more uplinks are permitted according to the request of terminal.
M can be equal to or less than by the quantity of the uplink subframe of more uplinks license schedulingSF.By more uplinks
The uplink subframe of license scheduling can be the continuous uplink subframe in time domain.For example, on continuous shown in Figure 15
Uplink subframe #2 to #7 can permit to dispatch by more uplinks.
More uplink licenses can be including at least one parameter described in table 4 and table 5.Also, more uplinks are permitted
It can also include the parameter described in call parameter and table 4 and table 5.
[table 5]
In fig.15, when using " more uplink license types 1 ", it may be configured to scheduling uplink subframe #4
More uplinks license A, and more uplinks license A can be included in the parameter described in table 4 and table 5 at least one
It is a.More uplinks license B of scheduling uplink subframe #5 is may be configured to, and more uplinks license B can be wrapped
Include at least one of parameter described in table 4 and table 5.It may be configured to more uplinks of scheduling uplink subframe #6
C is permitted on road, and more uplinks license C can be including at least one of parameter described in table 4 and table 5.
In fig.15, when using " more uplink license types 2 ", can be configured including public field and it is multiple individually
More uplinks license of field.Public field can include it is in the parameter described in table 4 and table 5, by UL subframe
At least one parameter that frame #4 to #6 is used in conjunction with.Each in independent field can be including the parameter described in table 4 and table 5
In the middle, for the different parameters of each in uplink subframe #4 to #6.It may be configured to uplink subframe #4
Independent field A, may be configured to the independent field B of uplink subframe #5, and may be configured to UL subframe
The independent field C of frame #6.For example, HARQ process numbers, RV, NDI, k, i, length letter in parameter described in table 4 and table 5
At least one of breath, channel access relevant information and SRS indexes can be included in each in independent field A, B and C
In.In the parameter listed in table 4 and table 5, the rest parameter (example in addition at least one parameter that independent field includes
Such as, MCS, resource block assignment information, TPC command etc.) public field can be included in.It is included in more uplink licenses
The type of public field and the parameter in independent field is not limited to above-mentioned example, and can be configured differently.
It then, will be in description mostly when using " more uplink license types 1 " or " more uplink license types 2 "
The embodiment of line link license.
■ HARQ process numbers
When using more uplink license types 1, HARQ process numbers can be included in more uplink licenses.
In Figure 15, the HARQ process numbers of uplink subframe #4 can be included in more uplink license A, uplink subframe #5
HARQ process numbers can be included in more uplinks license B, and the HARQ process numbers of uplink subframe #6 can be with
It is included in more uplink license C.Therefore, terminal can be based respectively on more uplink license A, B and C to identify uplink
The HARQ process numbers of link subframe #4 to #6.
Alternatively, it is possible to by more uplinks permit A be only sent in by more uplinks license scheduling it is multiple on
The HARQ process numbers of beginning uplink subframe (for example, uplink subframe #4) in uplink subframe, and in residue
The HARQ process numbers of uplink subframe (for example, uplink subframe #5 and #6) can not be permitted by corresponding uplink
(for example, more uplinks permit B and C) is sent.In this case, terminal can permit A to know based on more uplinks
The HARQ process numbers of other uplink subframe #4, and use beginning uplink subframe (for example, uplink subframe #4)
HARQ process numbers derive the HARQ process numbers of remaining uplink subframe (for example, uplink subframe #5 and #6).
HARQ process numbers can increase according to the increase of UL subframe frame number, and work as and permitted by more uplinks
When the HARQ process numbers for the uplink subframe #4 that A is obtained are x, the HARQ process numbers that can derive uplink subframe #5 are (x
+ 1), and can derive uplink subframe #6 HARQ process numbers be (x+2).In this case, terminal can use table
I described in 5 derives HARQ process numbers.When the maximum value of HARQ process numbers is y, terminal can use " x mod (complementation fortune
Calculating) y " determines the HARQ process numbers of uplink subframe #4, using " (x+1) mod y " determine uplink subframe #5's
HARQ process numbers, and " (x+2) mod y " is used to determine the HARQ process numbers of uplink subframe #6.Here, y can be
It is preset in base station and terminal.For example, base station can be by higher level signaling (for example, RRC signaling) to terminal notification y, and y can
To be 16.
Alternatively, it is possible to by more uplinks permit A come be sent in by more uplinks license scheduling it is multiple on
The actual value of the HARQ process numbers of beginning uplink subframe (for example, uplink subframe #4) in uplink subframe, and
And (for example, more uplinks permit B and C) can be permitted to send to starting UL subframe by corresponding more uplinks
Offset (hereinafter referred to as " the H of the HARQ process numbers of frame (for example, uplink subframe #4)off”).In this case,
Terminal can use HoffWith the uplink subframe by multiple uplink subframes of more uplinks license scheduling
The HARQ process numbers of (for example, uplink subframe #4) derive remaining subframe (for example, uplink subframe #5 and #6)
HARQ process numbers.Here, HoffCan be set to 0,1,2 ..., NSF-1。
As the H that the HARQ process numbers of uplink subframe #4 include for x and more uplinks license BoffIt, can when being 1
To derive the HARQ process numbers of uplink subframe #5 as (x+1).When the HARQ subframe numbers of uplink subframe #4 are x and more
The H that uplink license C includesoffWhen being 2, the HARQ process numbers that can derive uplink subframe #6 are (x+2).It is another
Aspect, when the maximum value of HARQ process numbers is y, terminal can use " x mod y " determine uplink subframe #4's
HARQ process numbers use " (x+Hoff(that is, 1)) mod y " determine the HARQ process numbers of uplink subframe #5, and use
“(x+Hoff(that is, 2)) mod y " determine the HARQ process numbers of uplink subframe #6.
When using more uplink license types 2, HARQ process numbers can be included in the list of more uplink licenses
In only field.In fig.15, the HARQ process numbers of uplink subframe #4 can be included in the independent of more uplink licenses
In field A, the HARQ process numbers of uplink subframe #5 can be included in the independent field B of more uplink licenses, and
And the HARQ process numbers of uplink subframe #6 can be included in the independent field C of more uplink licenses.Therefore, terminal
Independent field A, B and C can be based respectively on to identify the HARQ process numbers of uplink subframe #4 to #6.
Permit to dispatch by more uplinks alternatively, it is possible to only send by the independent field A that more uplinks are permitted
Multiple uplink subframes in beginning uplink subframe (for example, uplink subframe #4) HARQ process numbers, and
And the HARQ process numbers of remaining uplink subframe (for example, uplink subframe #5 and #6) can not pass through corresponding independent word
Section (for example, individually field B and C) is sent.In this case, terminal can permit A to identify based on more uplinks
The HARQ process numbers of uplink subframe #4, and use the HARQ for starting uplink subframe (for example, uplink subframe #4)
Process number derives the HARQ process numbers of remaining uplink subframe (for example, uplink subframe #5 and #6).
HARQ process numbers can increase according to the increase of UL subframe frame number, and work as and permitted by more uplinks
Independent field A (or public field) obtain uplink subframe #4 HARQ process numbers be x when, uplink can be derived
The HARQ process numbers of subframe #5 are (x+1), and the HARQ process numbers that can derive uplink subframe #6 are (x+2).Meanwhile
When the maximum value of HARQ process numbers is y, terminal can use " x mod y " to determine the HARQ processes of uplink subframe #4
Number, determine the HARQ process numbers of uplink subframe #5 using " (x+1) mod y ", and " (x+2) mod y " is used to determine
The HARQ process numbers of uplink subframe #6.
Alternatively, it is possible to it is sent by independent field A (or public field) that more uplinks are permitted by more uplinks
The beginning uplink subframe (for example, uplink subframe #4) in multiple uplink subframes that link license is dispatched
The actual value of HARQ process numbers, and can be permitted by more uplinks corresponding independent field (for example, individually field A,
B and C) come send to start uplink subframe (for example, uplink subframe #4) HARQ process numbers offset (hereinafter
It is referred to as " Hoff”)。
In this case, terminal can use HoffWith multiple uplink subframes by the license scheduling of more uplinks
The HARQ process numbers of beginning uplink subframe (for example, uplink subframe #4) in the middle derive remaining subframe (on for example,
Uplink subframe #5 and #6) HARQ process numbers.Here, HoffCan be set to 0,1,2 ..., NSF-1。
When the HARQ process numbers of uplink subframe #4 are x and the H that is included in independent field BoffIt, can be with when being 1
The HARQ process numbers for deriving uplink subframe #5 are (x+1).When the HARQ subframe numbers of uplink subframe #4 for x and are wrapped
Include the H in independent field CoffWhen being 2, the HARQ process numbers that can derive uplink subframe #6 are (x+2).On the other hand,
When the maximum value of HARQ process numbers is y, terminal can use " x mod y " determine the HARQ processes of uplink subframe #4
Number, use " (x+Hoff(that is, 1)) mod y " determine the HARQ process numbers of uplink subframe #5, and use " (x+Hoff
(that is, 2)) mod y " determine the HARQ process numbers of uplink subframe #6.
Based on said program, base station can be to terminal notification HARQ process numbers, and terminal can be more based on being included in
Information in uplink license identifies HARQ process numbers.
■RV
When using more uplink license types 1, RV can be included in more uplink licenses.In fig.15,
RV can be included in each of more uplink license A, B and C.Therefore, terminal can be based respectively on more uplinks
A, B and C is permitted to identify the RV of uplink subframe #4 to #6.
When using more uplink license types 2, RV can be included in the license of more uplinks public field or
In independent field.In fig.15, when in uplink subframe #4 to #6 use identical RV when, corresponding RV can by including
In the public field of more uplinks license.Therefore, terminal can be identified based on public field for uplink subframe #
4 to #6 RV.Alternatively, when using different RV in each uplink subframe #4 to #6, for UL subframe
The RV of frame #4 can be included in independent field A, can be included in independent field for the RV of uplink subframe #5
B, and can be included in independent field C for the RV of uplink subframe #6.Therefore, terminal can be based respectively on individually
Field A, B and C identify the RV of uplink subframe #4 to #6.
Alternatively, it is possible to RV is derived based on NDI.In this case, RV can be not included in more uplinks
In license.For example, RV variation sequence can be it is predefined, when NDI be " 0 " when can according to predefined variation sequence come
RV is set, and RV can be initialized as to initial value (for example, " 0 ") when NDI is " 1 ".It is in predefined variation sequence "
In the case of 0 → 2 → 1 ", once more uplinks license (or independent field) of the NDI including being arranged to " 0 " is received,
The RV of uplink subframe can be then set as to 2, and if more uplinks license of the NDI including being arranged to " 0 "
(or independent field) is received twice, then can be set as the RV of uplink subframe " 1 ".
In the case where using more uplink license types 1, when more uplinks license A includes being arranged to " 1 "
During NDI, the RV of uplink subframe #4 can be set as initial value (for example, " 0 ") by terminal.When more uplinks permit B packets
When including the NDI for being arranged to " 0 ", the RV of uplink subframe #5 can be set as " 2 " by terminal.When more uplinks permit C
During NDI including being arranged to " 0 ", the RV of uplink subframe #6 can be set as " 2 " by terminal.
In the case where using more uplink license types 2, when independent field A includes being arranged to " 1 " NDI when,
The RV of uplink subframe #4 can be set as initial value (for example, " 0 ") by terminal.When independent field B includes being arranged to " 0 "
NDI when, the RV of uplink subframe #5 can be set as by terminal " 2 ".When independent field C includes being arranged to " 0 " NDI
When, the RV of uplink subframe #6 can be set as by terminal " 2 ".
Based on said program, base station can be to terminal notification RV, and terminal can be based on being included in more uplinks
Information in license identifies RV.
■NSF
NSFIt can indicate the quantity of the uplink subframe by the license scheduling of more uplinks.NSFIt can be set to low
In MSF。
When using more uplink license types 1, NSFIt can be included in more uplink licenses.In fig.15,
NSFIt can be included in each in more uplink license A, B and C.Alternatively, due to being directed to uplink subframe #
4 to #6 are configured identical NSF, so NSFIt can be only included in more uplink license A.Alternatively, NSFIt can not
It is included in each in more uplink license A, B and C.In this case, NSFCan in base station and terminal quilt
It is default.When using more uplink license types 2, NSFIt can be included in the public field of more uplink licenses.
In Figure 15, NSFIt can be included in the public field of more uplinks license of scheduling uplink subframe #4 to #6.
It can be based on HARQ process numbers and NDI rather than NSFTo derive by the UL subframe of more uplinks license scheduling
The quantity of frame.In this case, NSFIt can be not included in the license of more uplinks.
For example, it can be derived based on effective HARQ process numbers by the uplink subframe of more uplinks license scheduling
Quantity.In fig.15, when the HARQ process numbers of uplink subframe #4 are x, the HARQ process numbers of uplink subframe #5 are
(x+1), when the HARQ process numbers of uplink subframe #6 are (x+2), the HARQ process numbers of uplink subframe #7 are x, uplink
The HARQ process numbers of link subframe #4 can be identical with the HARQ process numbers of uplink subframe #7.That is, work as MSFFor 4 simultaneously
And NSFWhen being 3, more uplink licenses can include the field of the HARQ process numbers of instruction uplink subframe #7.In this feelings
Under condition, the HARQ process numbers of uplink subframe #7 can be configured in the uplink subframe #4 to #6 with before by base station
The HARQ process numbers (for example, x, (x+1) or (x+2)) of one uplink subframe are identical.
When exist with identical HARQ process numbers multiple uplink subframes when, terminal can will have identical HARQ into
The first uplink subframe in time domain in multiple uplink subframes of journey number is determined as efficient uplink subframe.Cause
This, the uplink subframe #4 before uplink subframe #7 can be determined as efficient uplink subframe by terminal.Terminal can
To determine that uplink subframe #4 to #6 is permitted to dispatch and uplink subframe #7 is not by more uplinks by more uplinks
Permit to dispatch in road.In this case, since the efficient uplink subframe determined based on HARQ process numbers is uplink
Subframe #4 to #6, so terminal can determine more uplink license 3 uplink subframes of scheduling.
Alternatively, it is possible to it is derived based on HARQ process numbers and NDI by the uplink of more uplinks license scheduling
The quantity of subframe.That is, it is further contemplated that NDI permits the uplink subframe dispatched to derive by more uplinks
Quantity.
In the examples described above, it can identify and be removed on first in multiple uplink subframes with identical HARQ process numbers
The NDI of at least one uplink subframe except uplink subframe.Terminal can determine the NDI's for including being arranged to " 0 "
Uplink subframe is permitted to dispatch by more uplinks, and determines the uplink subframe for including being arranged to the NDI of " 1 "
Do not permit to dispatch by more uplinks.For example, when the NDI for being used for uplink subframe #7 is arranged to " 0 ", terminal can be with
Determine that uplink subframe #7 permits to dispatch by more uplinks.Therefore, terminal can determine more uplink license scheduling 4
Uplink subframe.Alternatively, if the NDI for uplink subframe #7 is arranged to " 1 ", terminal can determine
Uplink subframe #7 does not permit to dispatch by more uplinks.Therefore, terminal can determine more uplink license 3 uplinks of scheduling
Link subframe.
Based on said program, base station can be permitted the number of the uplink subframe of scheduling to terminal notification by more uplinks
Amount, and terminal can be identified based on the information in more uplink licenses is included in by the license scheduling of more uplinks
The quantity of uplink subframe.
■ l, k, i
L can represent the sending time of more uplink licenses and in multiple uplinks by the license scheduling of more uplinks
Interval between the sending time of the first uplink subframe (for example, starting uplink subframe) in way frame.L can be with
It is equal to or greater than zero integer.For example, l can be set to 4.
L can be sent to terminal in step S1600 via higher level signaling (for example, RRC signaling).Alternatively,
When using more uplink license types 1,1 can be included in more uplink licenses.In fig.15, l can distinguish
It is included in each in more uplink license A, B and C.Alternatively, due to being directed to uplink subframe #4 to #6
Identical 1 is configured, so 1 can be included in multiple uplink subframes for being dispatched by the license of more uplinks
In the more uplinks license A for starting uplink subframe (for example, uplink subframe #4).Permit when using more uplinks
During type 2, l can be included in the public field of more uplink licenses.In fig.15, l can be included in for
In the public field of more uplinks license of uplink subframe #4 to #6.
Meanwhile it can usually be permitted by the more uplinks sent by subframe #n come scheduling uplink subframe # (n+l)
To # (n+l+ (NSF- 1) transmission).However, due to network environment (for example, subframe structure etc.), uplink subframe #'s (n+l)
Sending may not permit to dispatch by the more uplinks sent by subframe #n.For example, by the license of more uplinks to
The scheduling of uplink subframe may be delayed by k.
In this case, k can indicate that dispatch delay deviates.When sending more uplinks licenses by subframe #n, k
It can indicate subframe # (n+l) and the practical offset started between uplink subframe (for example, subframe # (n+l+k)).Namely
It says, k can be the dispatch delay offset from subframe # (n+l).K may be greater than or null integer.The maximum value of k may
It can be restricted.For example, the maximum value of k can be 8 or 16.
When using more uplink license types 1, k can be included in more uplink licenses.In fig.15, k
It can be respectively included in each in more uplink license A, B and C.Alternatively, due to being directed to UL subframe
Frame #4 to #6 sets identical k, so k can be included in for by multiple UL subframes of more uplinks license scheduling
In more uplinks license A of beginning uplink subframe (for example, uplink subframe #4) in frame.When using more uplinks
During link license type 2, k can be included in the public field of more uplink licenses.In fig.15, k can by including
In the public field permitted for more uplinks of uplink subframe #4 to #6.
Meanwhile can the time using the license of more uplinks dynamically be set based on above-mentioned k.
Figure 17 is the concept map of the 3rd embodiment for the subframe for showing the scheduling in communication network.
With reference to figure 17, in unlicensed band, radio frames can include 10 subframes.For example, radio frames can include six
A uplink subframe, three downlink subframes and a special subframe.Base station can send more uplinks by subframe #0
Link permits to send with the uplink of scheduling subframe #5 and #6.P (that is, 1+k) can indicate permitting to adjust by more uplinks
Beginnings uplink subframe in multiple uplink subframes of degree with by its send the subframe of more uplinks licenses it
Between interval.P can changeably be set.If l is fixed value, P can be indicated by l and k.For example, as l=4, P can
With by l=4 and k=1 instructions.Alternatively, if l is variable value, P can be represented by l.That is, l can be set
It is 5.
Meanwhile i can indicate the index of each in the uplink subframe by the license scheduling of more uplinks.I can
To be arranged to 0,1 ..., NSF-1.For example, in the uplink subframe by the license scheduling of more uplinks, for the
The i of one uplink subframe (for example, starting uplink subframe) can be set to " 0 ", for the second uplink subframe
I can be set to " 1 ", and " N is can be set to for the i of last uplink subframeSF-1”。
When using more uplink license types 1, i can be included in more uplink licenses.In fig.15, i
It can be included in each in more uplink license A, B and C.For example, more uplink license A can include being set
The i of " 0 " is set to, more uplink license B can include being arranged to the i of " 0 ", and more uplinks license C can include
It is arranged to the i of " 0 ".Alternatively, i can be not included in each during more uplinks permit A, B and C.At this
In the case of kind, terminal can derive i according to ordering of sub-frames.
When using more uplink license types 2, i can be included in the independent field of more uplink licenses.
In fig.15, i can be included in each in independent field A, B and C of more uplink licenses.For example, independent word
Section A can include being arranged to the i of " 0 ", and independent field B can include being arranged to the i of " 1 ", and individually field C can be wrapped
Include the i for being arranged to " 2 ".
Meanwhile base station can using l, k and i come indicate by more uplinks permit (alternatively, public field, individually
Field) scheduling subframe numbers, and terminal can using l, k and i come identify by more uplinks license scheduling subframe numbers (or
Person, public field, independent field).In fig.15, when using more uplink license types 1, more uplink license A can
With include being arranged to the k of " 0 " and be arranged to " 0 " i (alternatively, be arranged to the l of " 4 ", be arranged to " 0 " k and
Be arranged to the i of " 0 "), more uplinks license B can include being arranged to the k of " 1 " and be arranged to " 0 " i (alternatively,
It is arranged to the l of " 4 ", be arranged to the k of " 1 " and is arranged to the i of " 0 "), and more uplinks license C can include
It is arranged to the k of " 2 " and is arranged to the i of " 0 " (alternatively, being arranged to the l of " 4 ", being arranged to the k of " 2 " and be set
I for " 0 ").In this case, based on l, k and i, terminal can identify that uplink subframe #4 permits A by more uplinks
Scheduling, uplink subframe #5 are dispatched, and uplink subframe #6 permits C by more uplinks by more uplinks license B
Scheduling.
In fig.15, when using more uplink license types 2, public field can include being arranged to the k of " 0 "
(alternatively, being arranged to " 4 " l and be arranged to the k of " 0 "), independent field A can include being arranged to the i of " 0 ", independent word
Section B can include being arranged to the l of " 1 ", and individually field C can include being arranged to the l of " 2 ".In this case, base
In l, k and i, terminal can identify that uplink subframe #4 is dispatched by public field and independent field A, uplink subframe #5 by
Public field and independent field B scheduling, and uplink subframe #6 is dispatched by public field and independent field C.Alternatively,
Each in independent field A, B and C can not include i.In this case, terminal can derive i according to ordering of sub-frames, and
And it is identified by the uplink subframe of each independent field scheduling based on l, k and the i of derivation.
That is, when sending more uplinks licenses by subframe #n, can permit adjust by more uplinks
The subframe # (n+l+k+i) of degree.If radio frames include 10 subframes, terminal can be known based on " n+l+k+i mod 10 "
Not by the subframe of more uplinks license scheduling.
Based on said program, base station can be to terminal notification l, k and i, and terminal can be based on being included in uplink
Road license in l, k and i come determine will by more uplinks permit dispatch subframe numbers.
■ length informations
It can changeably be set by the length of the uplink subframe of more uplinks license scheduling.For example, uplink
The length of way frame can changeably be set to perform channel access process.
Permit when by more uplinks come when dispatching multiple uplink subframes, length information includes multiple UL subframes
The starting position of beginning uplink subframe in frame and the end position for terminating uplink subframe, and can include multiple
The starting position of each and end position in uplink subframe.
Uplink subframe opens indicating in the multiple uplink subframes dispatched by the license of more uplinks
Beginning position can be referred to as " length type with the length information of at least one of the end position of end uplink subframe
1”.Indicate by more uplinks license scheduling multiple uplink subframes in each uplink subframe starting position and
The length information of at least one of end position can be referred to as " length type 2 ".

Based on said program, base station can be permitted the length of the uplink subframe of scheduling to terminal notification by more uplinks
Information is spent, and terminal can be permitted to adjust to identify based on the information being included in more uplink licenses by more uplinks
The length information of the uplink subframe of degree.
■ channel access relevant informations
When receiving more uplink licenses, terminal can be in the hair by more uplinks license scheduling uplink subframe
Before sending channel (or time slot) state is identified by performing channel access process.Channel access process can be LBT processes.Such as
Fruit channel status is confirmed as idle state, then terminal can be sent by the uplink subframe of more uplinks license scheduling.
On the other hand, if channel status is confirmed as busy state, terminal can not be sent by the license scheduling of more uplinks
Uplink subframe.
Channel access relevant information can include at least one of the following:Indicate whether the finger of execution channel access process
Show symbol (hereinafter referred to as " access indicator "), channel access procedural type (for example, Class1 or type 2) and channel
The run time of access procedure.
Access indicator can be classified as " access indicator type 1 " and " access indicator type 2 ".Access indicator
Class1 may indicate whether to perform channel access process in uplink subframe is started.Access indicator type 2 can indicate
Whether channel access process is performed in each in uplink subframe.
In fig.15, when using more uplink license types 1 and access indicator type 1, indicator type 1 is accessed
It can be included in each in more uplink license A, B and C.Since identical access indicator type 1 is set
When in uplink subframe #4 to #6, therefore only it can include accessing indicator type 1 in more uplinks license A.
Alternatively, when using more uplink license types 1 and access indicator type 2, for UL subframe
The access indicator type 2 of frame #4 can be included in more uplink license A, and the access for uplink subframe #5 refers to
Show that symbol type 2 can be included in more uplink license B, and for the access indicator type of uplink subframe #6
2 can be included in more uplink license C.When identical access indicator type 2 is arranged on uplink subframe #4
During into #6, only it can include accessing indicator type 2 in more uplinks license A.In this case, terminal can be with base
Determine whether in uplink subframe #4 to #6 in being included in the access indicator type 2 in more uplink license A
Perform channel access process.
In fig.15, when using more uplink license types 2 and access indicator type 1, indicator type 1 is accessed
It can be included in the public field of more uplinks license of scheduling uplink subframe #4 to #6.
Alternatively, when using more uplink license types 2 and access indicator type 2, for UL subframe
The access indicator type 2 of frame #4 can be included in independent field A, for the access indicator class of uplink subframe #5
Type 2 can be included in independent field B, and for uplink subframe #6 access indicator type 2 can by including
In independent field C.When identical access indicator type 2 is arranged in uplink subframe #4 to #6, access instruction
Symbol type 2 can be included in public field.
Meanwhile when base station and terminal are preconfigured to be the channel access process performed for sending uplink subframe
When, channel access relevant information can not include access indicator.Alternatively, it is possible to the length letter based on uplink subframe
Breath derives access indicator.In this case, channel access relevant information can not include access indicator.For example, work as root
When " 00 " is indicated in table 6 according to the starting position of each in length type 1 and length type 2, terminal can determine not hold
Row channel access process.When the starting position of each in length type 1 and length type 2 indicated in table 6 " 01 ",
During one in " 10 " and " 11 ", terminal can determine that channel access process will be performed.When according to length type 1 and length type
When the end position of each in 2 indicates " 0 " in table 7, terminal can determine not performing channel access process.When according to length
When the end position of each in degree Class1 and length type 2 indicates " 1 " in table 7, terminal can determine that channel will be performed
Access procedure.
Channel access procedural type can be classified as " channel access procedural type 1 " and " channel access procedural type 2 ".
When using channel access procedural type 1, terminal can randomly choose backoff counter, and if channel in competition window
State during the backoff counter corresponding period with being determined to be in idle state, then terminal can send uplink
Subframe.Alternatively, if channel status is true during " with backoff counter+delay duration corresponding period "
It is set to and is in idle condition, then terminal can sends uplink subframe.It is preferential that contention window size can be based on channel access
Grade determines.For example, base station can determine contention window size based on table 8.CWminIt can indicate that given channel access is preferential
The minimum value of competition window in grade sequence, and CWmaxIt can indicate competition window in given channel access priority most
Big value.
[table 8]
Channel access priority | CWmin | CWmax |
1 | 3 | 7 |
2 | 7 | 15 |
3 | 15 | 1023 |
4 | 15 | 1023 |
When using channel access procedural type 2, terminal can identify channel shape during specific time period (such as 25 μ s)
State, and if channel status is the free time, send uplink subframe.Alternatively, terminal can be corresponding to " when specific
Channel status is identified during the period of section (for example, 25 μ s)+additional time ", and if channel status is the free time, can be sent out
Serve uplink subframe.
In fig.15, when using more uplink license types 1, for the channel access process of uplink subframe #4
Type (for example, Class1 or type 2) can be included in more uplink license A, for the channel of uplink subframe #5
Access procedure type (for example, Class1 or type 2) can be included in more uplink license B, and UL subframe
The channel access procedural type (for example, Class1 or type 2) of frame #6 can be included in more uplink license C.Work as uplink
When channel access procedural type in link subframe #4 to #6 is arranged to identical, channel access procedural type is (for example, Class1
Or type 2) more uplink license A can be only included in.In this case, terminal can be based on being included in more uplinks
Link permits the channel access procedural type (for example, Class1 or type 2) in A to perform to send uplink subframe #4
To the channel access process of #6.
In fig.15, when using the channel access in more uplink license types 2 and uplink subframe #4 to #6
When procedural type is arranged to identical, channel access procedural type (for example, Class1 or type 2) can be included in scheduling
In the public field of more uplinks license of uplink subframe #4 to #6.Alternatively, when using more uplink permission class
Type 2 and when being arranged differently than channel access procedural type in each uplink subframe #4 to #6, for UL subframe
The channel access procedural type (for example, Class1 or type 2) of frame #4 can be included in independent field A, for uplink
The channel access procedural type (for example, Class1 or type 2) of subframe #5 can be included in independent field B, and for
The channel access procedural type (for example, Class1 or type 2) of uplink subframe #6 can be included in independent field C.
Meanwhile can channel access procedural type be derived based on the length information of uplink subframe.In this case,
Channel access relevant information can not include channel access procedural type.For example, when according in length type 1 and length type 2
The starting position of each when " 01 " or " 10 " is indicated in table 6, terminal can determine to use channel access procedural type 2.
When the starting position of each in length type 1 and length type 2 indicates " 11 " in table 6, terminal can determine
Use channel access procedural type 1.When the end position of each in length type 1 and length type 2 refers in table 7
When showing " 1 ", terminal can determine to use channel access procedural type 1.
The run time of channel access process can be set with table 9 based on following.In table 9, current uplink way
Frame can be by the uplink subframe of more uplinks license (or independent field) scheduling.
[table 9]
Value | Description |
00 | The symbol #0 of time slot #0 in uplink subframe is started |
01 | The symbol #6 of time slot #1 in the previous subframe for starting uplink subframe |
10 | The symbol #0 of time slot #0 in current uplink subframe |
11 | The symbol #6 of time slot #1 in the previous subframe of current uplink subframe |
In fig.15, when using more uplink license types 1, channel access process in uplink subframe #4
Run time can be included in more uplinks license A, during the operation of the channel access process in uplink subframe #5
Between can be included in more uplinks license B, and the run time of the channel access process in uplink subframe #6
It can be included in more uplink license C.Alternatively, when the channel access process in uplink subframe #4 to #6
Run time be identical, the run time of channel access process can be only included in more uplinks license A.At this
In the case of kind, terminal can be performed based on the run time for the channel access process being included in more uplink license A
Channel access process in uplink subframe #4 to #6.
In fig.15, when using more uplink license types 2 and the channel in uplink subframe #4 to #6 connects
When entering the run time of process and being arranged to identical, the run time of channel access process can be only included in more uplinks
In the public field of license.Alternatively, when using in more uplink license types 2 and uplink subframe #4 to #6
When the run time of channel access process is set differently, for the channel access process of uplink subframe #4 operation when
Between can be included in independent field A, the run time for the channel access process of uplink subframe #5 can be wrapped
It includes in independent field B, and the run time for the channel access process of uplink subframe #6 can be included in list
In only field C.
Meanwhile the run time of channel access process can be derived based on the length information of uplink subframe.This
In the case of, channel access relevant information can not include the run time of channel access process.For example, when according to length type 1
Starting position when one in " 01 ", " 10 " and " 11 " is indicated in table 6, terminal can determine the operation of channel access process
Time is the symbol #0 for starting the time slot #0 in uplink subframe.When the starting position according to length type 2 indicates in table 6
" 01 ", " 10 " and " 11 " and in one when, terminal can determine that the run time of channel access process is current uplink way
The symbol #0 of time slot #0 in frame.
Based on said program, base station can be to terminal notification channel access relevant information, and terminal can be identified and be wrapped
Include the channel access relevant information in the license of more uplinks.
■ SRS indexes
SRS indexes can indicate wherein to send in multiple uplink subframes by the license scheduling of more uplinks
At least one uplink subframe of SRS.It for example, can be based on multiple uplink subframes by the license scheduling of more uplinks
The first uplink subframe (for example, start uplink subframe) in the middle sets SRS indexes.For example, table 10 can be based on
To set the SRS indexes of the uplink subframe #4 to #6 shown in Figure 15.
[table 10]
SRS indexes | Subframe numbers |
00 | #4 |
01 | #5 |
10 | #6 |
11 | Retain |
When SRS indexes include " 00 ", " 01 " and " 10 ", terminal can be by each in uplink subframe #4 to #6
A transmission SRS.Alternatively, if SRS indexes only include " 01 ", terminal can send SRS by uplink subframe #5,
And cannot SRS be sent by uplink subframe #4 and #6.
Also, in the license of more uplinks, SRS request and SRS indexes can be configured as independent field (hereinafter
It is referred to as " SRS fields ").When SRS is asked to send in uplink subframe, SRS fields can be included in more uplinks
In the license of road.If SRS is not asked to send in uplink subframe, SRS fields can be not included in more uplinks
In license.
When using more uplink license types 1, SRS indexes (or SRS fields) can be included in more uplinks
Permit in each in A, B and C.For example, when sending SRS in uplink subframe #4, it is arranged to the SRS ropes of " 00 "
Drawing can be included in more uplink license A, and when not sending SRS in uplink subframe #4, SRS indexes can
To be not included in more uplinks permit A.When sending SRS in uplink subframe #5, it is arranged to the SRS of " 01 "
Index can be included in more uplink license B, and when not sending SRS in uplink subframe #5, SRS indexes
It can be not included in more uplinks permit B.When sending SRS in uplink subframe #6, it is arranged to " 10 "
SRS indexes can be included in more uplink license C, and when not sending SRS in uplink subframe #6, SRS
Index can be not included in more uplinks permit C.
When using more uplink license types 2, SRS indexes (or SRS fields) can be included in dispatching uplink chain
In the public field of more uplinks license of way frame #4 to #6.Alternatively, SRS indexes (or SRS fields) can be wrapped
It includes in each in the independent field permitted in more uplinks.For example, when sending SRS in uplink subframe #4,
Being arranged to the SRS indexes of " 00 " can be included in independent field A, and works as and do not sent in uplink subframe #4
During SRS, SRS indexes can be not included in independent field A.When sending SRS in uplink subframe #5, it is arranged to
The SRS indexes of " 01 " can be included in independent field B, and when not sending SRS in uplink subframe #5, SRS
Index can be not included in independent field B.When sending SRS in uplink subframe #6, it is arranged to the SRS of " 10 "
Index can be included in independent field C, and when not sending SRS in uplink subframe #6, and SRS indexes can not
It is included in independent field C.
Based on said program, base station can be to terminal notification SRS indexes, and terminal can identify and be included in more uplinks
SRS indexes in link license.
Meanwhile base station can generate the DCI permitted including more uplinks.More uplinks can be permitted based on RNTI
It is scrambled.And the form of the DCI including the license of more uplinks can be 0A, 0B, 4A or 4B.
When using more uplink license types 1, can generate for each in multiple more uplink licenses
DCI.In fig.15, it can generate for the DCI of more uplinks license A, can generate for more uplinks license B's
DCI, and can generate for the DCI of more uplinks license C.Can based on public RNTI generate DCI in each (or
More uplink license A, B and C of person).
When using more uplink license types 2, can generate for public field single DCI and be included in it is more
Independent field in uplink license.In figure 16, can generate including public field, independent field A, independent field B and
The single DCI of independent field C.
Base station can send DCI (S1630) by PDCCH/EPDCCH.Terminal can pass through monitoring (or detection) PDCCH/
EPDCCH obtains more uplink licenses (S1640) to receive DCI from the DCI received.Here, terminal can be based on
RNTI obtains DCI (that is, more uplinks are permitted).In fig.15, when using more uplink license types 1, terminal can be with
It is obtained using identical RNTI and permits A, B and C for the more uplinks of each in uplink subframe #4 to #6.It can replace
Ground is changed, when using more uplink license types 2, terminal can obtain more uplinks for uplink subframe #4 to #6
Permit (that is, public field and independent field A, B and C) in road.
Meanwhile when the receive capabilities for activating more uplink licenses, terminal can receive more uplink licenses.At this
In the case of kind, terminal can not perform the reception operation of conventional uplink license (for example, single uplink license).
Terminal can send (S1650) based on the information being included in more uplink licenses to perform uplink.
In fig.15, terminal can be confirmed that the transmission of uplink subframe #4 to #6 is permitted to dispatch by more uplinks.Terminal can be with base
It is confirmed whether to perform channel access in the channel access relevant information or length information that are included in more uplink licenses
Process.When performing channel access process before uplink subframe #4 to #6 is sent, terminal can be based on channel access phase
Information, length information etc. are closed to identify run time and channel access procedural type.
Terminal can be performed at the run time of channel access process based on the channel access procedural type identified
Channel access process.For example, terminal can be in symbol #0 (or the uplink subframe #3 of the time slot #0 of uplink subframe #4
The symbol #6 of time slot #1) in perform channel access process, and when channel status is determined to be in idle state, then terminal can
To send uplink subframe #4 to #6.I.e., it is possible to perform UL subframe in the case of no additional channel access procedure
The transmission of frame #5 and #6.
Alternatively, terminal can be in symbol #0 (or the uplink subframe #3 of the time slot #0 of uplink subframe #4
Time slot #1 symbol #6) in perform channel access process, and when channel status is determined to be in idle state, terminal
Uplink subframe #4 can be sent.Terminal can be in symbol #0 (or the uplinks of the time slot #0 of uplink subframe #5
The symbol #6 of the time slot #1 of subframe #4) in perform channel access process, and when channel status is determined to be in idle state
When, terminal can send uplink subframe #5.Terminal can be in the symbol #0 (on or of the time slot #0 of uplink subframe #6
The symbol #6 of the time slot #1 of uplink subframe #5) in perform channel access process, and when channel status is determined to be in sky
During not busy state, terminal can send uplink subframe #6.It that is, can be each in uplink subframe #4 to #6
A middle execution channel access process.
When determining that channel status is in idle condition or performs uplink in the case of no channel access process
During transmission, terminal can be with collocating uplink link subframe.Specifically, during terminal can be permitted based on more uplinks are included in
NSF, at least one of l, k and i identify the subframe numbers sent for uplink.In fig.15, terminal can be by subframe #4
It is determined as uplink subframe to #6.Terminal can identify use based on the length information in more uplink licenses is included in
