First, brief description is applicable to a typical scene of the present invention.Under this typical scene, constitute a homogeneous network by multiple base station, include but not limited to the small cell cluster of high-density deployment.Each base station in this network is connected with same common control equipment, this common control equipment can be can with the various equipment of base station communication, such as OAM equipment or an independent macro base station.This common control equipment can carry out Signalling exchange by each base station in corresponding signaling interface and homogeneous network, such as, when common control equipment is macro base station, X2 interface can be used to carry out Signalling exchange.Subscriber equipment in homogenous networks in each base station is divided into again two groups, and one group is normal users, is not namely subject to the part user disturbed between neighbor cell, typical in Cell Center User; Another group is victim user, is namely subject to the part user disturbed between neighbor cell, typical in Cell Edge User.
According to the first step of carrying out the method for resource distribution of the present invention, be carry out initialized configuration by above-mentioned common control equipment, namely each base station receives the ICIC initializes configuration information issued from this common control equipment, and this information is sent by the first message.In order to realize object of the present invention, at least need to comprise the configuration information in following 3 in this message:
The pattern of 1.ICIC configuration.Which namely, for each base station, need sub-frame configuration to become ICIC subframe.When carrying out initial configuration, common control equipment can according to predefined rule, or according to the configuration of operating personnel, or according to various modes such as network traffic conditions at that time, determine how many sub-frame configuration should be become ICIC subframe, and determine the distribution of these ICIC subframes further, then the subframe numbers being defined as ICIC subframe is sent to each base station respectively by above-mentioned first message.Preferably, can represent the distribution of ICIC subframe with the first bitmap, namely each bit of the first bitmap represents a subframe respectively, and the set on any bit position on the first bitmap just represents that the subframe corresponding to this bit is confirmed as ICIC subframe; Such as, in LTE system, we can represent the circulation of 40 period of sub-frame with the bitmap of 40, such representation can save the expense of signaling.
The pattern of 1.FFR configuration.Namely, for each base station, need which frequency range on the frequency band of ICIC subframe to be configured to public part, which frequency range is configured to quadrature component; Wherein so-called public part represents these frequency ranges is that adjacent community can use, main to normal users use in above-mentioned community, quadrature component is then that neighbor cell uses respectively, mutually different, these quadrature components are mainly for victim user in above-mentioned community, the frequency band used due to these victim user can not use by neighbor cell, therefore can effectively avoid this part user to be subject to the impact of presence of intercell interference.Preferably, the distribution of FFR frequency band can be represented with the second bitmap, namely each bit of the second bitmap represents the one group of Resource Block (resource block is called for short RB) on the frequency band of ICIC subframe, and the set on any bit position on the second bitmap just represents that group RB corresponding to this bit is configured to quadrature component.Such as, in LTE system, for the frequency band of a 10MHz bandwidth, one has 110 RB, and 5 RB are divided into one group, 22 groups altogether, so can represent the configuration of this bandwidth with the bitmap of 22, same, such representation can save the expense of signaling.
3. activate the information in the moment of above-mentioned configuration.This information is for notifying that each base station starts to activate above-mentioned configuration on a certain particular point in time.This particular point in time can be expressed by various possible mode, such as, directly provide the moment of activation, or provides some specific subframe numbers, represents to activate above-mentioned configuration from this subframe.

Concrete, first, in the first message that above-mentioned first step receives, except aforesaid information, further comprises the information of to carry out the report of ICIC subframe utilization rate for configuring each base station to this common control equipment.Typically, this information can be that informing base station was reported with the specific cycle, or certain predefined event of informing base station can trigger this report.
Next, complete in base station after the 3rd step activates the work of configuration, start to carry out the 4th step, namely each base station is that all user device configuration two in this community overlap limited measurement parameter, wherein, this two covers parameter corresponds respectively to ICIC subframe and other subframe.The object configuring this two covers parameter carries out limited measurement for each subscriber equipment respectively to these two kinds of subframes; Therefore, as preferred scheme, the limited measurement parameter about Radio Link Management (radio link management is called for short RLM), RRM (radio resourcemanagement is called for short RRM) and channel status instruction (channel state indication is called for short CSI) at least will be comprised in parameter, like this can limited measurement mechanism under good compatible existing protocol.
Then subscriber equipment will carry out limited measurement to ICIC subframe and other subframes respectively according to this two covers parameter, and obtain after measurement two covers channel qualities instruction (Channelquality indicator is called for short CQI) are sent to base station.So five steps is exactly base station receive all subscriber equipmenies send this two cover CQI.It is pointed out that the limited measurement also supporting sub-band levels when subscriber equipment carries out limited measurement.Like this, the CQI obtained just can include the CQI in all relevant subbands; That is, for ICIC subframe, the CQI of the subband belonging to FFR part can be obtained, and for other subframes, then can obtain the CQI of all subbands within the scope of channel.Above-mentioned CQI will be used to the scheduling of resource (channel-awared scheduling) of channel-aware.
5th step, base station is according to the transmission cycle of aforementioned definitions, or specific time triggered, sends the report of ICIC subframe service condition, be i.e. have how many Resource Block to be serve victim user in the ICIC subframe of this configuration to common control equipment.
Finally, base station receives the second message sent from this common control equipment, wherein comprises this common control equipment according to the ICIC pattern after pre-defined rule adjustment and the configuration information of FFR pattern, so just achieves the function of dynamic conditioning of the present invention.Concrete, predetermined regulation rule can be, if when the utilization rate of the ICIC subframe that base station uses is less than the first thresholding, the frequency band reducing ICIC subframe belongs to the Resource Block of quadrature component, utilization rate mentioned here is exactly the ratio that the Resource Block of serving victim user in the 5th step takies in whole ICIC subframe.When utilization rate is lower, illustrate that disturbed condition is not serious, only need less orthogonal frequency resources just can meet the sequence needs of victim user, therefore can reduce quadrature component, increase public part, improve the frequency usage efficiency of system.Similar, if when the utilization rate of the ICIC subframe of base station use is greater than the second thresholding, the frequency band of increase ICIC subframe belongs to the Resource Block of quadrature component.When utilization rate is higher, illustrates that disturbed condition is comparatively serious, need more orthogonal frequency resources just can meet the sequence needs of victim user, therefore can increase quadrature component, reduce public part, ensure the normal work of subscriber equipment.
Figure 2 illustrate according to another embodiment of the invention, in this embodiment,
Give a kind of specific ICIC configuration mode, for the situation that presence of intercell interference is extremely serious.In this case, interference between neighbor cell strongly, to such an extent as to had influence on the normal transmission of Physical Downlink Control Channel (physical downlink control channel is called for short PDCCH), because PDCCH needs to carry out encoding and transmitting in whole bandwidth range, so can interact between the common transmission part of neighbor cell, thus cause normally working.Therefore a kind of special ICIC pattern is devised, namely in a series of ICIC subframe, some specific subframes are selected, it is special that these specific subframes are configured to specific base station, that is, for these specific subframes, except above-mentioned specific base station can use, outside other adjacent base stations all keep mourning in silence in these specific sub-frame, do not make any downlink, above-mentioned specific base station would not be interfered with like this.And for this certain base station, because this specific sub-frame is configured to, it is special, and all RB therefore in whole subframe channel should be configured to quadrature component, thus use by this certain base station.As shown in Figure 2, the adjacent base station of Cell1 is Cell2 to Cell7, subframe numbers 5,6, the subframe of 7 is configured to ICIC subframe, wherein, for Cell1, subframe 5 is its special specific sub-frame, and all RB of whole frequency band are configured to the quadrature component of Cell1, corresponding for Cell2 to Cell7, just need to keep mourning in silence in subframe 5.Same, above-mentioned configuration information is also sent to each base station by aforementioned first message from common control equipment, equally also can carry out dynamic conditioning according to aforesaid method.
