Description

The method of power division, base station, subscriber equipment and system
Technical field
The present invention relates to the communications field, particularly the method for power division, base station, subscriber equipment and system.
Background technology
In a wireless communication system, when carrying out downlink transfer, UE (UserEquipment, subscriber equipment) can the CQI (ChannelQualityIndication of real-time measurement downlink transfer, channel quality indicates), and returning to base station residing for it by recording the CQI result obtained, the effect of downlink transfer according to the CQI of UE for this UE Resources allocation is to carry out downlink transfer, can be improved in base station.
Meanwhile, in a wireless communication system, in order to avoid the signal of the Base Transmitter of neighbor cell is to the interference of UE and the channel quality improving this community, usually can distribute downlink transmission power.Currently used downlink transmission power allocative decision is the power grade of the UE division downlink transfer in community, carry out using specific power grade when downlink data sends for each UE, such as concrete can be when base station at a time needs to send downlink data to the UE being in cell edge, then current descending power is set to high power, high power is used to send downlink data to this UE, when at a time needing to send downlink data to the UE being in center of housing estate, then current descending power is set to low-power, low-power is used to send downlink data to this UE.
Particularly, Figure 1 shows that when using current downlink transmission power allocative decision, the resource allocation conditions of two neighbor cells in certain period and frequency resource.Wherein, system comprises two adjacent community cell1 and cell2, and each community comprises two UE, is respectively high power UE (UE h 1, UE h 2) and low-power UE (UE l 1, UE l 2).Wherein, subscript represents the community belonging to UE, subscript represents power grade, the bandwidth that downlink transfer is carried out in the base station of each community is divided into three sub-bands, high power resource representation moment shown in the figure uses high power to carry out downlink data transmission to high power UE, and low-power resource representation moment shown in the figure uses low-power to carry out downlink data transmission to low-power UE.
But inventor is realizing finding in process of the present invention that prior art exists following defect:
Situation as shown in Figure 1, at the 1st moment UE h 1be subject to the high power interference of neighbor cell cell2, at the 8th moment UE h 1be subject to the low-power interference of neighbor cell cell2, at these two moment UE h 1all can measure the CQI of current time and return to network side, but, UE h 1return CQI to network side and have certain time-delay, network side can not know the CQI in the 8th moment in time the 8th moment, therefore still can adopt the 1st moment UE in this moment h 1cQI resource is dispatched, but there occurs acute variation the 8th moment relative to the downlink transmission power in the 1st moment in fact due to neighbor cell cell2, cause the CQI in the CQI in the 1st moment and the 8th moment to there occurs larger change, at this moment network side cannot be UE timely h 1select optimum modulation coding mode and Resource Allocation Formula according to the CQI of reality, thus have influence on UE gulp down tolerance.
Therefore, adopt existing downlink transmission power distribution method, may due to the acute variation of the downlink transmission power of neighbor cell, larger fluctuation is produced to the CQI result that UE measurement obtains, and instant CQI can not be obtained due to time delay network side, when CQI fluctuation is larger, the scheduling result of network side to UE can be had influence on, good Resourse Distribute effect and throughput can not be produced.
