GBR_CEU
S103, indicate the OC frequency bandwidth and the position of this sub-district of integrated information and state reference value adjustment in advance according to the adjacent area high interference;
HIPIGBRThr1, HIPIGBRThr2 satisfy first, second status threshold values of state for the whole GBR of expression this sub-district CEU; HIPIGBRThr1 representes that the whole GBR of this sub-district CEU satisfies state first status threshold values preferably, the state reference value T when this sub-district
GBR_CEUDuring＞HIPIGBRThr1, it is better that the whole GBR that representes the CEU of this sub-district satisfies state, and promptly the OC frequency band of this sub-district enough satisfies the demand of CEU; HIPIGBRThr2 representes that the whole GBR of this sub-district CEU satisfies the second relatively poor status threshold values of state, the state reference value T when this sub-district
GBR_CEUDuring＜HIPIGBRThr2, it is relatively poor that the whole GBR that representes the CEU of this sub-district satisfies state, and promptly the OC frequency band of this sub-district is not enough to satisfy the demand of CEU;
Definite principle of HIPIGBRThr1, two threshold values of HIPIGBRThr2 is following: for each sub-district; When the triggering of each adjustment OC frequency band arrives constantly, satisfy the state reference value T of state according to the whole GBR of the CEU of this sub-district of method statistic described in the step S102

ThresholdNeibHIPI is the threshold value that the adjacent area high interference is indicated integrated information in advance, is illustrated on the subband adjacent area high interference and indicates integrated information to be higher than this thresholding in advance, and then high interference will be caused to this sub-district in the adjacent area on this subband;
Concrete, for the LTE system up-link, HIPIGBRThr1 is HIIGBRThr1, and HIPIGBRThr2 is HIIGBRThr2, and ThresholdNeibHIPI is ThresholdNeibHii;
S104, generate the preparatory indication information of high interference of this sub-district and send to each adjacent area according to the adjusted OC frequency bandwidth in this sub-district and position.
The position of OC frequency band promptly is meant OC frequency band shared resource location in system bandwidth;
For the LTE system up-link, the preparatory indication information of high interference is the HII indication information, and for the LTE system down link, the preparatory indication information of high interference is a RNTP information.
Is the scheme that example specifies the embodiment of the invention below in conjunction with accompanying drawing with the HII information of the up link of LTE system.
The method of adjustment of a kind of HII indication information that the embodiment of the invention provides, as shown in Figure 2, specifically comprise:
S201, UE (subscriber equipment) access network, the UE type is confirmed in the base station;
Base station side RRC (Radio Resource Control; Radio Resource control) layer is divided the starting type that inserts UE according to the A3 trigger event; MAC (Media Access Control, medium access control) layer of GBR according to UE satisfies state and can readjust the UE type;
The UE type is divided into CCU (Cell Center User; Cell Center User) and CEU; CCU and CEU can be by the Serving cell of UE measurement and report and the RSRP of adjacent sub-district (Reference Signal Received Power; Reference Signal Received Power) or RSRQ (Reference Signal Received Quality, Reference Signal Received Quality) differentiate, the MAC layer can also satisfy the adjustment that state carries out the UE type according to the GBR of UE;
Each sub-district is handled as follows:
S202, base station obtain OC, IC (Inner Cell, the center of housing estate zone) frequency band of current time sub-district, and the initial indication information of the HII of definite sub-district;
Suppose that each base station is covered by M1 sub-district; Then the whole system bandwidth is divided into M1 frequency band; And guarantee that each frequency band is not overlapping and mutually orthogonal; The initial OC frequency band of representing M1 sub-district respectively, the initial OC frequency band non-overlapping copies of all sub-districts under the base station then, the system bandwidth outside each cell initial OC frequency band is its initial IC frequency band; To each sub-district, its Neighboring Cell List is by the decision of the rrc layer of base station side, and the adjacent area should be chosen and this area interference those adjacent areas greater than certain thresholding, specifically can consider and factors such as the distance of this sub-district and antenna direction; Because the sub-district of existence and local area OC band overlapping in the Neighboring Cell List, so the suggestion rrc layer is given cell configuration with this sub-district identical initial OC, the IC frequency band less with the interference of this sub-district;
When initial, the base station is the initial OC of cell allocation, IC frequency band, and OC, IC band information that the HII indication information is used for identifying cells are set, and sends to the adjacent area; The base station is provided with the bit map of HII indication, and HII is designated as 1 frequency band and representes the OC frequency band, and HII is designated as 0 frequency band and representes the IC frequency band;
In the subsequent process, OC, the IC band information of the HII indication information acquisition sub-district of base station generation are constantly triggered according to last one in the base station;
S203, arrive predetermined this sub-district of adjustment OC frequency band triggering constantly, judge whether to obtain adjacent area HII integrated information, judged result when being, execution in step S205, judged result when denying, execution in step S204;
Set the triggering moment of initial this sub-district of adjustment OC frequency band; The long renewal of the processing window of follow-up fixed interval triggered constantly, and fixing processing window is long generally greater than the time of delay of X2 interface, sets as required simultaneously; It is long too small to handle window; It is serious that then interface signaling frequently causes the X2 interface load alternately, if it is long excessive to handle window, then the renewal of the HII indication information of sub-district can be untimely;
S204, the OC that keeps this sub-district, IC frequency band are constant, and the HII indication information when the HII indication information triggers as this is constantly triggered in last one of this sub-district;
When triggering for the first time, if do not obtain adjacent area HII integrated information, the HII indication information of this sub-district when the HII indication information when initial triggers as this;
The whole GBR of S205, acquisition expression this sub-district CEU satisfies the state reference value of state;
Be specially: a, add up this sub-district and when last one triggers, be carved into this and trigger the actual flow of all CEU constantly;
B, basis
The whole GBR that obtains expression this sub-district CEU satisfies the state reference value T of state

Wherein, R
iThe actual flow of representing i CEU; GBR
iAll professional GBR summations of representing i CEU; N
CEUThe sum of representing CEU in this sub-district; Wi representes the service priority weight of i CEU, generally gets the highest priority of logical channels of this UE priority.
S206, according to the OC frequency bandwidth and the position of this sub-district of adjacent area HII integrated information and state reference value adjustment;
S207, generate the HII indication information of this sub-district, and each specifies adjacent area with the HII information of this sub-district sends to this sub-district according to the adjusted OC frequency bandwidth in this sub-district and position;
S208, when needs transmission data, dispatch according to the HII indication information of this sub-district;
Constantly promptly in each transmitting uplink data; Dispatch according to the HII indication information of this sub-district the base station; CEU only dispatches on HII is designated as 1 OC resource; CCU is designated as at HII on 0 the IC resource and dispatches, if the OC resource has residue, CCU also can dispatch on remaining OC resource;
S209, arrival HII information processing are constantly; Weighted sum is carried out to the HII information of the adjacent area on each subband that receives in the base station, obtains the adjacent area HII integrated information
on each subband
Wherein, the initial treatment that the moment that receives the HII information of all adjacent areas to this sub-district first is decided to be this sub-district HII information constantly, the long update processing of the processing window of follow-up fixed interval is constantly; Processing window length in this step and the triggering processing window length constantly among the step S203 can be the same or different;
Arrive when handling constantly; The HII information of the adjacent area on each subband is carried out weighted sum to be handled; Wherein the interference of the weights of each adjacent area reflection adjacent area and this sub-district is big or small; Thereby obtain the HII integrated information of the adjacent area on each subband, the reference quantity of the interference that the adjacent area that the HII integrated information of each subband is illustrated in this sub-district on this subband will produce this sub-district;
Wherein, the execution of step S209 can not limit the execution sequence of step S209 in embodiments of the present invention in any time between step S201～S208.
Wherein among the step S206 according to the OC frequency bandwidth and the position of this sub-district of adjacent area HII integrated information and state reference value adjustment; Main adjustment strategy is: when the whole GBR of this sub-district CEU satisfies state when better; Represent the OC frequency band of this sub-district enough to satisfy the demand of CEU, then can the OC frequency band of this sub-district be dwindled; When the whole GBR of this sub-district CEU satisfies state when relatively poor; Represent the OC frequency band of this sub-district to be not enough to satisfy the demand of CEU; Then can the OC frequency band of this sub-district be enlarged, satisfying the demand of CEU, simultaneously to the OC frequency band dwindle with expansion process in; Need consider the disturbance regime that adjacent sub-district will produce this sub-district, promptly need consider the adjacent area HII integrated information on each subband.
For down link, then the base station is provided with OC, the IC band information of RNTP message identification sub-district, and sends to the adjacent area; The base station is provided with the bit map of RNTP indication, and RNTP is designated as 1 frequency band and representes the OC frequency band, and RNTP is designated as 0 frequency band and representes the IC frequency band, and processing procedure and HII information process are similar; And in step S208, then in each downlink data transmission constantly, dispatch according to the RNTP information of this sub-district the base station.
