Specific implementation mode
It, will be with reference to the appended attached drawing for constituting a present invention part in the specific descriptions of following preferred embodiment.Institute
Attached attached drawing, which has been illustrated by way of example, can realize specific embodiment.Exemplary embodiment is not intended to
Limit all embodiments according to the present invention.It is appreciated that without departing from the scope of the present invention, other can be utilized
Embodiment can also carry out structural or logicality modification.Therefore, it is below specific descriptions and it is unrestricted, and this
The range of invention is defined by the claims appended hereto.
First, the purpose that resource allocation information transmission is carried out to realize the present invention between the base station of heterogeneous network, needs
Multiple base stations in heterogeneous network are divided into two groups, one of which base station receives the resource allocation information that another group of base station is sent out.
For the sake of being described below conveniently, receiving resource allocation information is known as first base station group below, resource allocation information will be sent
Be known as the second group of base stations.Specific grouping strategy can carry out different selections according to actual network structure.It is most typical,
It can be grouped by base station type, i.e., the macro base station in network is divided into one group, micro-base station is divided into another group.It must be pointed out
It is that it is not influence the realization of the present invention that first base station group or the second group of base stations are assigned in what type of base station；I.e. no matter
Either micro-base station all can serve as to receive or send a side of resource allocation information macro base station.
Attached drawing 1 shows that typical isomerism network structure, i.e., the macrocell of one eNB cover the Microcell of multiple RRH,
To constitute a heterogeneous network covered mutually.Without loss of generality, it is first base station group that can divide macro base station eNB,
All micro-base station RRH (RRH1 to RRH3) are divided into the second group of base stations.(as described above, on the contrary, being the by multiple RRH point
One group of base stations, the method for being equally applicable the present invention by an eNB points for the second group of base stations.)
One of embodiment according to the present invention, first, each RRH in the second group of base stations are respective ePDCCH points
With resource, the eNB that is then sent to resource information used in respective ePDCCH by first message in first base station group；So
Afterwards, the eNB in first base station group has known all RRH in the second group of base stations according to all these first messages received
Resource used in ePDCCH；Finally, eNB carries out the resource allocation of its ePDCCH according to these known information, the distribution
Principle is to make on eNB that resource used in ePDCCH is different from resource used in ePDCCH and all RRH.In this way, logical
The transmission for carrying out ePDCCH using different resources respectively on two groups of base stations is crossed, the ePDCCH on eNB can be made to transmit not
Serious inter-cell interference is generated as to the ePDCCH channels on RRH, to realize the purpose of the present invention.As described above,
The role for exchanging eNB and RRH is equally possible.At this point, its ePDCCH resources used are sent to respectively by eNB by first message
A RRH, and each RRH distributes respective ePDCCH resources accordingly so that respective ePDCCH resources are used with ePDCCH on eNB
Resource differ.It should be noted that in this case, the resource used on the ePDCCH of each RRH is likely to be that
This is identical.However, since the transmission power of micro-base station RRH is generally smaller, i.e. between each Microcell where RRH
Inter-cell interference is far below the inter-cell interference between macrocell and Microcell, therefore the interference problem between micro-base station RRH is simultaneously
It is not serious, being remarkably decreased for channel quality will not be actually caused, there is no need to specially separate ePDCCH resources on RRH.This
The advantages of sample designs is interacted without further message between RRH, under the premise of not influencing performance, saves signaling overheads.
Attached drawing 2 show carried out according to the present invention it is after cooperation resource allocation results, it can be seen that ePDCCH on eNB
It is separated from each other with resource used in the ePDCCH on RRH, there is no mutually overlapping mutually, so as to which ensure will not be same
Serious inter-cell interference is generated in one frequency.
According to another embodiment of the invention, with above-described embodiment difference lies in：Each RRH of second group of base stations
It is sending except first message, is also sending second message respectively, which is used to indicate the respective reference powers of these RRH
Threshold information, this reference power threshold information gives the interfering signal power upper limit that can bear at these RRH, i.e., dry
When disturbing signal no more than the thresholding, the interference caused by the RRH can be received.And correspondingly, eNB in first base station group
According to first message and second message, resource used in ePDCCH on each RRH had both been known, also known each RRH institutes
Receptible maximum interference power, therefore different equipping rules can be used when eNB carries out ePDCCH configurations, it both can be with
In an embodiment as above, the distribution resource different from the ePDCCH on each RRH；Can also use on some RRH
The identical resources of ePDCCH, but the reference power thresholding that transmission power is not more than the RRH is configured simultaneously, so that it is guaranteed that even if using
Same resource will not significantly interfere the channel of the RRH.Obviously, the configuration of this embodiment is more flexible, especially suitable
It is more for base station number, the situation of channel resource deficiency.Ibid an embodiment is identical, and the realization of the present embodiment also relies on essence
Really know that resource used in ePDCCH on each RRH, such eNB just can determine that the reference power thresholding that should use which RRH
Information is configured.So crucial place of the invention is that and carries out information exchange to resource used in ePDCCH.
Preferably, resource used in ePDCCH can be described with bandwidth and position in the present invention.Go out as shown in Fig. 2
, RRH can by shared by respective ePDCCH bandwidth and position eNB is informed by first message, and eNB is then selected accordingly
The ePDCCH of oneself is distributed in one section of bandwidth not being occupied and position.The advantages of this design is that information is intuitively accurate.
Another kind preferably describes resource used in ePDCCH with a bitmap (bitmap), is referred to as here
For the first bitmap.Each bit in the first bitmap then represents a resource block in system bandwidth, that is to say, that the
The bit number of one bitmap is determined by system bandwidth.And the set on some bit has just represented corresponding resource block accordingly
It is used.Therefore the corresponding bit of resource block used in its ePDCCH can be carried out set by each RRH, then by set
The first bitmap afterwards is sent to eNB by first message；And eNB then from either with or without by the bit of any one RRH institutes set
In selected, that is, never selected in the resource block used in any one RRH, distribute to oneself
ePDCCH.The advantages of this design is that algorithm realizes simple and convenient.
The transmission of first message in the present invention can be realized by arbitrary inter-base station interface, such as can be specifically designed
New interface or special purpose interface, can also be to be to provide more preferably using the benefit of existing X2 interface using existing X2 interface
Downward compatibility, only several new message formats need to be designed in existing X2 interface.
The present invention can also realize the newer function of dynamic, specifically, if some RRH in the second group of base stations needs more
Resource used in its new ePDCCH can send change message to the eNB in first base station group, be contained in the change message
Used resource information after the ePDCCH changes of the RRH, and eNB then reconfigures its ePDCCH accordingly so that on eNB
Resource after the resource and the RRH that ePDCCH is used are changed also differs.It is opened in order to avoid frequently changing the additional signaling brought
Pin can configure a change cycle parameter, i.e., only allow once to be changed in one change period.
