Quasi- HetNet) framework, to achieve the purpose that carry out unified resource configuration to the terminal in macrocell and picocell coverage area, such as
It is V-HetNet configuration diagram shown in Fig. 2.
From figure 2 it can be seen that macro base station and micro-base station colocation site, colocation site described here refer to where macro base station
Site on increase high directionality antenna sets (such as array antenna group or electromagnetic horn), the high directionality antenna sets and macro base station are logical
Optical fiber interconnections are crossed, which forms the covering to Microcell by way of Beam synthesis, micro- specifically to undertake
The function of base station, by the beam position, beam angle, the angle of declination, transmission power that adjust each antenna in high directionality antenna sets
Deng can easily change the size and location of Microcell.
Under V-HetNet framework, between macro base station and micro-base station can shared baseband system, realize channel between the two
Information and data information it is shared, and the backhaul of high speed high capacity may be implemented in the mode of macro base station and micro-base station colocation site
(backhaul) mechanism；For the terminal in Microcell, macro base station and micro-base station can reach the terminal simultaneously, thus can be by
Macro base station completes the United Dispatching of resource.
The embodiment of the present invention proposes a kind of transmission plan of new downgoing control signal, based on macro base under V-HetNet framework
It stands and the characteristic of micro-base station colocation site, it is unified in macrocell and picocell coverage area using the resource in a carrier wave
Terminal carries out resource distribution, is used for transmission the macro terminal and pico terminal being located in Microcell and macrocell juncture area
The resource of downgoing control signal keeps orthogonal, and the terminal being located in Microcell and macrocell juncture area is mainly controlled with macro base station
Terminal under terminal and micro-base station under system mainly control is used for transmission the resource of downgoing control signal and also keeps orthogonal, it can be ensured that
The downgoing control signal transmission process of terminal is smaller by inter-cell interference；Further, since the downlink of all terminals controls letter
It number is all transmitted in the same carrier wave, avoids the wasting of resources caused by terminal quantity difference in different zones.
It should be noted that being provided in the embodiment of the present invention to the terminal being located in Microcell and macrocell coverage area
The equipment of source configuration can be with macro base station, and the component being also possible in macro base station, the embodiment of the present invention is referred to as Resource Scheduler.
In the scheme of the embodiment of the present invention, Resource Scheduler marks off first area, second area shown in Fig. 1 and third
The mode in region includes but is not limited to static division mode and two kinds of dynamic division mode.
The static division mode refers to: according to fixed partition mode uniquely mark off first area, second area and
Third region, hereafter, the division in these three regions no longer change.The static division mode is using the first fixed threshold
Value, second threshold and third threshold value mark off changeless first area, second area and third region.
The dynamic division mode refers to: can be according to terminal distribution situation (i.e. the location information of terminal), mobile management
Demand, communication quality demand and channel status etc. divide condition, negotiate to determine first area, second by macro base station and micro-base station
Region and third region.The dynamic division mode using can dynamic change first threshold, second threshold and third threshold
Value marks off first area, second area and third region.
For example, in network busy hour, it is crowded in hot spot region, it is possible to increase first threshold expands the range in third region,
The load for mitigating macro base station provides network service for the biggish business demand amount of hot zones by Microcell；In network idle,
First threshold can be reduced, the range in third region is reduced, in extreme circumstances, or even micro-base station, whole region can also be closed
All it is managed collectively by macro base station.
Resource Scheduler can be fully transparent to terminal for the division of first area, second area and third region, eventually
End is without knowing locating region itself.
The present invention program is described in detail below by specific embodiment.
Embodiment one:
As shown in figure 3, for the transmission method signal of the downgoing control signal based on V-HetNet in the embodiment of the present invention one
Figure, the method mainly comprise the steps that
Step 101: Resource Scheduler determines a carrier wave for bearing downlink control signal.
The resource of downgoing control signal is used for transmission in the scheme of the present embodiment, between macro base station and micro-base station and terminal
The same carrier wave, therefore, can set for bearing downlink control signal a carrier wave physical resource complete or collected works as M, resource
The physical source distributing of the M to the terminal in macro base station and micro-base station coverage area, is used under terminal transmission by scheduler
Row control signal.
Step 102: the part resource in the carrier wave is determined as the macro terminal positioned at second area by Resource Scheduler
Carry out the resource of downgoing control signal transmission.
Resource Scheduler can be referred to as M_Bm for resource collection determined by the macro terminal positioned at second area.
Step 103: another part resource in the carrier wave is determined as the pico positioned at second area by Resource Scheduler
The resource of terminal progress downgoing control signal transmission.
Resource Scheduler can be referred to as M_Bp for resource collection determined by the pico terminal positioned at second area, in order to drop
Low level area interference suffered by the terminal of second area, it is desirable that M_Bm and M_Bp are orthogonal.
Step 104: Resource Scheduler be determined as from the surplus resources in the carrier wave terminal positioned at first area into
The resource of row downgoing control signal transmission.
Resource Scheduler is after configuring resource positioned at the terminal of second area, and remaining resource, which refers in M, removes (M_Bm+
M_Bp the resource after), resource set of the Resource Scheduler in the resource of M-M_Bm-M_Bp to be configured positioned at the terminal of first area
Conjunction can be referred to as M_A, at this point, M_A is orthogonal with M_Bm and M_Bp respectively.
Step 105: Resource Scheduler be determined as from the surplus resources in the carrier wave terminal positioned at third region into
The resource of row downgoing control signal transmission.
Surplus resources involved in this step 105 refer in M the resource after removing (M_Bm+M_Bp), Resource Scheduler
Can be in the resource of M-M_Bm-M_Bp to configure resource positioned at the terminal in first area and third region, Resource Scheduler is position
The resource collection that terminal in third region configures can be referred to as M_C, at this point, M_C is orthogonal with M_Bm and M_Bp respectively, but M_A
Relationship between M_C is simultaneously not fixed, and is allowed M_A and M_C to be multiplexed completely or M_A and M_C fractional reuse, be may also allow for M_A
Orthogonal with M_C, the present embodiment does not limit the relationship between M_A and M_C, this is because being located at first area and third area
The area interference of the terminal in domain to each other is smaller, therefore recoverable resources carries out the transmission of downgoing control signal.
By taking the present embodiment is applied in LTE-A as an example, a carrier wave for bearing downlink control signal is 20MHz,
In step 102 and step 103, Resource Scheduler can be according to the quantity for being currently located at second area macro terminal and pico terminal
And/or active state, orthogonal M_Bm is determined respectively from 20MHz for the macro terminal and pico terminal positioned at second area
And M_Bp；In step 104 and step 105, Resource Scheduler from remaining resource (i.e. 20MHz-M_Bm-M_Bp) for positioned at
The terminal of first area and the terminal in third region determine M_A and M_C.
Match at this point, completing the resource for carrying out downgoing control signal to the terminal in macro base station and micro-base station coverage area
It sets, wherein configuration result
In the scheme of above step 102 to step 105, Resource Scheduler is that the resource that the terminal in each region configures can be with
It is one section of continuous resource, is also possible to discrete resource, the resource available resource set description of distribution.
It should be noted that step 102 in the present embodiment to step 105 execution sequencing and be not fixed, it is a kind of
Feasible sequence are as follows: first to configure orthogonal resource M_A and M_ positioned at the macro terminal of the terminal of first area and second area
After Bm, then to configure resource M_Bp positioned at the pico terminal of second area from remaining M-M_A-M_Bm, finally again from M-M_
For positioned at the terminal in third region configuration resource M_C in Bp-M_Bm.Certainly, the present embodiment be also not necessarily limited to it is other execute sequence,
It no longer enumerates one by one herein.
Step 106: the corresponding terminal of resource notification that Resource Scheduler will determine for each terminal, it is desirable that terminal is according to reception
To notification message receive downgoing control signal from corresponding resource.
Since the terminal in macro base station and micro-base station coverage area may change constantly, for example, have new terminal into
Enter first area, or the terminal positioned at first area is moved to second area etc. originally, therefore, above step 102 to step
106 can be repeated continuously execution, it is ensured that dry when terminal transmission downgoing control signal in macro base station and micro-base station coverage area
It disturbs smaller.
Step 107: Resource Scheduler instruction macro base station and micro-base station are according to determining resource to residing in itself terminal
Carry out the transmission of downgoing control signal.
One scheme through the embodiment of the present invention is respectively positioned at first area and second area on the same carrier wave
Terminal configures orthogonal resource, configures orthogonal resource for the terminal positioned at second area and third region, while for positioned at the
The macro terminal and pico terminal in two regions also configure orthogonal resource, can effectively reduce terminal positioned at second area into
The inter-cell interference that row downgoing control signal is subject to when transmitting；Simultaneously as only using one in the scheme of the embodiment of the present invention
Carrier wave, it is less to the usage amount of resource, even if terminal quantity is reduced in region, the serious wasting of resources will not be caused, even
When being located at all macro terminals of terminal or pico terminal of second area, due to for positioned at the terminal distribution of second area
Resource be a carrier wave part resource, the wasting of resources is also serious.In addition, resouce controller is being not necessarily to additional signaling
In the case where expense, so that it may which even adjustment makes for positioned at each region the resource for being located at terminal distribution in each region to dynamic in real time
The resource of interior terminal distribution preferably meets the actual demand of terminal.
Preferably, it is assumed that positioned at all pico terminals of the terminal of second area, the pico for being now placed in second area is whole
The transmission process of downgoing control signal between end and the pico terminal in third region will not interfere, positioned at second area
Terminal can be located at third region terminal multiplexing resource, meanwhile, positioned at third region terminal be located at first area end
End can also be with multiplexed resource, therefore, and the terminal positioned at third region can occupy the resource of entire carrier wave to carry out downlink control letter
Number transmission；To be orthogonal with the resource for the terminal distribution positioned at second area positioned at the resource of the terminal distribution of first area,
Ensure that the terminal for being located at second area is small in the inter-cell interference be subject to when downgoing control signal transmission.
Preferably, by taking the embodiment of the present invention is applied in LTE system as an example, in the frame structure of LTE system, preceding 2 OFDM
(Orthogonal Frequency Division Multiplexing, orthogonal frequency division multiplexing) symbol is used for transmission downlink control
Signal, rear 12 OFDM symbols are used for transmission data-signal.Assuming that the step 102 and step 105 in embodiment one are resource tune
Spending device is the process that the terminal in each region configures frequency domain resource, then corresponds in the time domain, positioned at the macro terminal of second area
It can be multiplexed identical OFDM symbol completely with pico terminal, as shown in Fig. 4 (A)；Positioned at the macro terminal and pico of second area
Terminal can also fractional reuse OFDM symbol, as shown in Fig. 4 (B)；Macro terminal and pico terminal positioned at second area can also make
With orthogonal OFDM symbol, as shown in Fig. 4 (C).In addition to this, the embodiment of the present invention is not also to positioned at first area and third area
Corresponding whether be multiplexed in the time domain of the frequency domain resource of the terminal distribution in domain is defined.
Other than the description that the scheme come by taking the frame structure of LTE system as an example above to the embodiment of the present invention carries out, this hair
Bright embodiment can also apply the frame structure of UMB (Ultrawide Mobile Band, Ultra Mobile Broadband) system of 3GPP2,
1.25MHz is specially separated in the bandwidth of 5M is used for transmission control signal.The embodiment of the present invention is not to being used for transmission downlink control
Used frame structure limits when signal, as long as the resource for being used for transmission downgoing control signal is the side with the embodiment of the present invention
Case determines.

Downgoing control signal and PHICH (Physical Hybrid Automatic Repeat-reQuest Indicator
Channel, entity hybrid automatic repeat request indication channel) on downgoing control signal, carry out PDCCH on downlink control
When the transmission of signal, the scheme of embodiment one can be used to carry out the transmission of downgoing control signal；Similar, on carrying out PHICH
Downgoing control signal (such as ACK/NACK) transmission when, it is possible to use the scheme of embodiment one carries out the biography of downgoing control signal
It is defeated.
Preferably due to which the position of PHICH can be indicated by the downgoing control signal in PDCCH, according to this characteristic, only
The terminal that be located at second area has determined the position of PHICH by the downgoing control signal in PDCCH, even if being located at the secondth area
The marco terminal and pico terminal in domain without using orthogonal resource come transmit the downgoing control signal on PHICH (or even multiplexing phase
Same running time-frequency resource), the downgoing control signal on the PHICH received can also correctly be parsed, be avoided due to cell
Between interference lead to not be properly received, parse the problem of downgoing control signal.
Following example two to transmit the downgoing control signal on downgoing control signal and PHICH on PDCCH for example,
The scheme of the embodiment of the present invention one is described in detail.
Embodiment two:
In the scheme of the embodiment of the present invention two, according to embodiment one step 101 to step 106 scheme, for everybody
It is configured to the resource of the downgoing control signal on transmission PDCCH in the terminal in region, later, Resource Scheduler indicates macro again
Base station and micro-base station carry out the transmission of the downgoing control signal on PDCCH according to determining resource to the terminal for residing in itself.
Due to including DCI (Downlink Control Information, downlink in the downgoing control signal on PDCCH
Control information), and carried in DCI format 0 (DCI format 0) in the group number (group number) and group of PHICH just
It hands over sequence number (orthogonal sequence index within the group), is notified when terminal in Resource Scheduler
After receiving DCI in resource, the orthogonal sequence number in the group number and group of PHICH can be therefrom identified, for any two terminal
The DCI received, wherein it is different for having at least one parameter in orthogonal sequence number in the group number and group that carry, it may be assumed that
The orthogonal sequence number in PHICH group that the two terminals receive the group number difference of PHICH or the two terminals receive
Orthogonal sequence number in the group number and group of the PHICH that different or the two terminals receive is all different.At this point, the group of PHICH
Number and group in orthogonal sequence number can the unique identification PHICH, therefore, no matter terminal is received on PHICH by which kind of resource
Downgoing control signal (as the macro terminal and pico terminal multiplexing resource that are located at second area receive the downlink on PHICH
Control signal) when, all using the orthogonal sequence number in the group number and group of the PHICH carried in DCI on the PHICH received
Downgoing control signal correctly parsed.
This is because: the macro terminal and pico terminal that are located at second area receive itself and are stayed in multiplexed resource
The interference that will receive the downgoing control signal that other base stations are sent when the downgoing control signal that the base station stayed is sent simultaneously, leads to end
End can not correctly parse the downgoing control signal received.Using the scheme of the present embodiment two, due in V-HetNet framework
The synchronism of macro base station and micro-base station between identical site, base station is secure, therefore, if what each terminal received
Orthogonal sequence number in the group number and group of PHICH is not exactly the same (in the group number and group of the PHICH that i.e. each terminal receives just
Hand over sequence number orthogonal), it will be able to guarantee that terminal is effective for the decoding of the downgoing control signal (such as ACK/NACK) on PHICH
Property, at this point, terminal is not influenced for the decoding of the downgoing control signal on PHICH by inter-cell interference.
Two scheme through the embodiment of the present invention, the downlink that need to be only carried out on PDCCH according to the scheme of embodiment one control
The transmission of signal, and then the downgoing control signal on PHICH can be carried out according to the parameter that the DCI on PDCCH is carried correct
Parsing, relative to the scheme of embodiment one, the scheme of the embodiment of the present invention two be can be applied to for the downlink control on PHICH
When the transmission of signal, the case where macro terminal and pico terminal multiplexing resource (including the whole money of multiplexing part resource or multiplexing
Source), if resource used in macro terminal and pico terminal is orthogonal, macro terminal and pico terminal are in transmission PHICH
On downgoing control signal when will not generate interference problem, but this mode for using orthogonal resource can make radio resource by compared with
It mostly occupies, therefore, using the scheme of the embodiment of the present invention two, the money that macro terminal and pico terminal use can be indifferent to
Whether source is orthogonal or multiplexing can also save radio resource the macro terminal and pico terminal multiplexing resource the case where；Together
When, due to marco and pico colocation site, in the case where not introducing overhead, the present embodiment two also may be implemented
Scheme.
In order to preferably mitigate macro base station load, the terminal for being located at second area can be all considered as pico terminal, applied
In V-HetNet framework, the terminal for being located at second area can be referred to as vpico terminal.In the scheme of above-described embodiment two
In, not to cell ID used by the macro terminal and vpico terminal positioned at second area for being located at first area
(cell id) is limited, and can be used positioned at the macro terminal of first area and positioned at second area vpico terminal identical
Different cell id can also be used in cell id.
Preferably, it is assumed that the macro terminal positioned at first area and the vpico terminal positioned at second area are using different
The cell id of cell id, i.e. macro terminal and vpico terminal are orthogonal, then when macro base station and micro-base station are under resident terminal
It, can be according to the cell id couple of macro terminal and vpico terminal when sending out downgoing control signal (such as ACK/NACK) on PHICH
ACK/NACK is scrambled (scramble) operation accordingly.In the case, even if receiving each terminal multiplexing of ACK/NACK
Identical running time-frequency resource, and the orthogonal sequence number in the group number and group of the PHICH in the DCI received is identical, due to macro end
End is orthogonal with the cell id of vpico terminal Scrambling Operation, is still able to guarantee the decoding validity that terminal is directed to ACK/NACK.
