The present embodiment is applicable to distribute in the process of PCI into the member carrier in polymerization carrier wave.The executive agent of the present embodiment can be for example base station.
The carrier wave that carries out transfer of data, in the time of UE access network, is determined in base station in the present embodiment, is above-mentioned allocation of carriers PCI; In the time that the carrier wave of transfer of data is carried out in increase, be above-mentioned allocation of carriers PCI; In the time that the carrier wave of transfer of data is carried out in minimizing, discharge the PCI of above-mentioned carrier wave, the PCI dischargeing can distribute to other carrier wave of other base station, in the time dischargeing the PCI of carrier wave and be again activated, the different PCI that can distribute and originally discharge.Carry out the carrier wave of transfer of data in increase after, UE can obtain CRS (public reference signal, Common Reference Signal) by newly assigned PCI and carry out data demodulates and measurement.Each step in the present embodiment can be used separately or be used in combination with other step.So just can not have the carrier wave of transfer of data still to take the situation of a PCI.Thereby the problem that has solved distributable PCI lazy weight and aggravate PCI conflict.
Fig. 2 is the schematic diagram that the embodiment of the present invention is distributed PCI.The method of the distribution PCI that the present embodiment provides comprises:
Step 201, in the time of UE access network, determines the carrier wave that carries out transfer of data, is above-mentioned allocation of carriers PCI; And/or
Step 202, in the time that the carrier wave of transfer of data is carried out in increase, is above-mentioned allocation of carriers PCI; And/or

The present embodiment is applicable to distribute in the process of PCI into the member carrier in polymerization carrier wave.The executive agent of the present embodiment can be for example base station.
The carrier wave that carries out transfer of data, in the time of UE access network, is determined in base station in the present embodiment, is above-mentioned allocation of carriers PCI; In the time that the carrier wave of transfer of data is carried out in increase, be above-mentioned allocation of carriers PCI; In the time that the carrier wave of transfer of data is carried out in minimizing, discharge the PCI of above-mentioned carrier wave, the PCI dischargeing can distribute to other carrier wave of other base station, in the time dischargeing the PCI of carrier wave and be again activated, the different PCI that can distribute and originally discharge.
In distributing PCI, can be dominated by base station, such as get rid of the PCI that neighbor base station has used from PCI set to be selected, then select PCI, and associated with the carrier wave that carries out transfer of data; Or select PCI from PCI set to be selected, and associated with the carrier wave that carries out transfer of data, if there is PCI conflict, reselect and association, until there is not PCI conflict; Also can be leading by operation management maintain OAM system, such as, base station sends and distributes request to operation management maintain OAM system, and the PCI of reception OAM system feedback is also associated with the carrier wave that carries out transfer of data, and at this moment the PCI of OAM system assignment is just pass in base station.
In two kinds of methods of salary distribution of being dominated by base station, base station all needs to select PCI, in selecting PCI, can select independently PCI, such as when the UE access network, define two carrier waves and will carry out transfer of data, be respectively so them and distribute 0 and 2, or 2 and 8, for another example in the time that UE increases carrier wave, the carrier wave of an original transfer of data, PCI is 0, now for this allocation of carriers PCI increasing is 1 or 9; Or select the identical PCI of PCI that another carrier wave that carries out transfer of data uses with self, such as carrier wave or another definite carrier wave of legacy data transmission, PCI is 0, also distributes 0 for new carrier wave now; Or the be separated by PCI of special value of the PCI that selects the carrier wave that carries out transfer of data with self another to use, such as carrier wave or another definite carrier wave that legacy data transmits, PCI is 0, also distributes 0+n for new carrier wave now, n is arbitrary integer; Or select another carrier wave that carries out transfer of data uses with self PCI phase PCI on the same group, every 30 of 504 PCI are one group and have been divided into 17 groups, and they are respectively 0-29,30-59 ..., 480-504.Such as carrier wave or another definite carrier wave of legacy data transmission, PCI is 1, and this PCI is in first group, also distributes the PCI in first group for new carrier wave now, i.e. 0-29; Or select another carrier wave that carries out transfer of data uses with self PCI phase on the same group but not identical PCI, such as carrier wave or another definite carrier wave of legacy data transmission, PCI is 1, this PCI is in first group, now for new carrier wave also distributes the PCI that is different from 1 in first group, 0,2-29.
In the PCI having used in eliminating base station, can receive that UE reports, the PCI having been used by neighbor base station being detected by UE, and delete from PCI set to be selected, such as, UE finds that adjacent cell is being used PCI 3, this information is sent to base station, and just delete 3 after receiving from the PCI set to be selected of oneself base station; Or base station itself is provided with a receiver, near the signal of base station transmitting receiving, and parse PCI, from PCI set to be selected, delete.Each step in the present embodiment can be used separately or be used in combination with other step.
So just can not have the carrier wave of transfer of data still to take the situation of a PCI.Thereby solve the problem of distributable PCI lazy weight aggravation PCI conflict, reduce the possibility of PCI conflict, thereby reach the effect of good interference randomization, the present invention selects another carrier wave that carries out transfer of data uses with self PCI mutually on the same group but not identical PCI, further three cubes of CM values of reduction in addition.
