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 wireless communication system; When carrying out downlink transfer, CQI (the Channel Quality Indication of the measurement downlink transfer that UE (User Equipment, subscriber equipment) can be real-time; The channel quality indication); And will record the CQI result who obtains and return to its residing base station, the base station can according to the CQI of UE for this UE Resources allocation to carry out downlink transfer, improve the effect of downlink transfer.
Simultaneously, in wireless communication system, to the interference of UE with improve the channel quality of this sub-district, can distribute downlink transmission power usually for fear of the signal of the base station of neighbor cell.The downlink transmission power allocative decision that is adopted at present is that the UE in the sub-district divides the power grade of downlink transfer; Carry out using when downlink data sends specific power grade to each UE; For example concrete can be at a time need be when the UE that is in cell edge sends downlink data when the base station; Then current descending power is set to high power, uses high power to send downlink data to this UE, need be when the UE that is in center of housing estate sends downlink data when at a time; Then current descending power is set to low-power, uses low-power to send downlink data to this UE.
Particularly, shown in Figure 1 under the situation of using present downlink transmission power allocative decision, the resource allocation conditions of two neighbor cells on certain period and the frequency resource.Wherein, comprise two adjacent sub-district cell1 and cell2 in the system, each sub-district 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 is represented the sub-district under the UE; Subscript is represented power grade; The bandwidth that downlink transfer is carried out in the base station of each sub-district is divided into three sub-frequency bands, and the high power resource representation moment shown in the figure uses high power to carry out downlink data transmission to high power UE, and the low-power resource representation moment shown in the figure uses low-power to carry out downlink data transmission to low-power UE.
But the inventor finds that in realizing process of the present invention there is following defective in prior art:
Situation as shown in Figure 1 is at the 1st moment UE H 1The high power that receives neighbor cell cell2 disturbs, at the 8th moment UE H 1The low-power that receives neighbor cell cell2 is disturbed, at these two moment UE H 1All can measure and return to network side the CQI of current time, still, UE H 1Return CQI to network side and have certain time-delay, network side can not in time be known the CQI in the 8th moment the 8th moment, therefore still can adopt the 1st moment UE in this moment H 1CQI resource is dispatched; But in fact since neighbor cell cell2 with respect to the downlink transmission power in the 1st moment acute variation has taken place the 8th moment; Cause the CQI and the CQI in the 8th moment in the 1st moment that bigger change has taken place, at this moment network side can't be UE timely H 1CQI according to reality selects optimum modulation coding mode and Resource Allocation Formula, thereby has influence on the tolerance that gulps down of UE.
Therefore; Adopt existing downlink transmission power distribution method, may be owing to the acute variation of the downlink transmission power of neighbor cell, the CQI result that UE is measured produces bigger fluctuation; And because the time delay network side can not obtain instant CQI; When the CQI fluctuation is big, can have influence on the scheduling result of network side to UE, can not produce resource allocation effect preferably and throughput.

Further; Before the power grade of confirming each descending sub frame in the cycle that is provided with; Can confirm the power grade of downlink transfer in the current area Cell1 earlier; Promptly the required power of using of each descending sub frame in the Cell1 is carried out power grade and divide, concrete, comprise following three kinds of methods at least:
Method one: the UE in the Cell1 of sub-district is divided into different UE set; And the downlink transmission power of sub-district Cell1 is divided into the different power grade according to above-mentioned different UE set, make a kind of power grade of downlink transmission power of each UE set respective cell Cell1;
Wherein, the UE in the Cell1 of sub-district is being divided into the UE set of different capacity grade, the concrete division that can carry out the UE set of different capacity grade according to following one or more methods:
A, obtain the channel quality of the UE in the Cell1 of sub-district, the UE of channel quality in different preset channel mass ranges is divided into different UE set;
B, obtain the interference strength that the UE in the Cell1 of sub-district receives, the UE of interference strength in different preset range is divided into different UE set;
C, obtain UE receives in the Cell1 of sub-district the available signal and the ratio of interference signal, the UE of this ratio in the preset ratio range of difference is divided into different UE gathers;
D, the throughput when obtaining the downlink data of the descending power transmission of each grade of UE reception use in the Cell1 of sub-district; Calculate the throughput that UE improves when receiving the downlink data of a downlink transmission power grade transmission of every raising, be divided into the UE set of different capacity grade according to the UE of throughput in different preset throughput scope that improves;
For example, in the present embodiment, when the throughput of the UE in the Cell1 of sub-district when receiving the signal that high power sends surpasses throughput when using low-power to send and reach preset threshold values, then this UE is divided in the high power UE set;
E, obtain UE residing position in the Cell1 of sub-district in the Cell1 of sub-district, the UE in the Cell1 of sub-district is divided into different UE set according to the residing position of UE.For example, the UE that will be in Cell1 center, sub-district is divided into low-power UE set, and the UE commonly used that will be in cell edge is divided into high power UE set.
Method two:, confirm the power grade of downlink transfer in the current area Cell1 according to the disturbed condition information between current area and the neighbor cell;
For example, as shown in Figure 5, sub-district Cell1 produces bigger interference to the UE of sub-district Cell2, need comprise the power grade of lower downlink transfer so in the Cell1 of sub-district; As shown in Figure 6, sub-district Cell2 produces bigger interference to the UE of sub-district Cell1, need comprise the power grade of higher downlink transfer so in the Cell1 of sub-district;
Method three: the numerical value set (the numerical value set of the power grade of stipulating in the prior art standard for example) according to preset power grade is divided into the different power grade with the power of downlink transfer in the current area.
For example, before dividing the downlink transmission power grade for the sub-district, preset standard, the numerical value set of a power grade of definition in standard is if the set of values of the power grade of standard definition is combined into S E, the power grade of downlink transmission power is S in the current area so EOr S EA sub-set.

The overall channel capacity of b, the overall channel capacity of obtaining high power UE set and low-power UE set, and the ratio of the overall channel capacity of gathering according to the overall channel capacity of high power UE set and low-power UE are confirmed the ratio of high power subframe and low-power subframe;
C, according to the disturbed condition information between current area and the neighbor cell, confirm the ratio of high power subframe and low-power subframe;
For example, as shown in Figure 5, sub-district Cell1 produces bigger interference to the UE of sub-district Cell2, need use the less high power subframe and the ratio of low-power subframe so; As shown in Figure 6, sub-district Cell2 produces bigger interference to the UE of sub-district Cell1, need use the bigger high power subframe and the ratio of low-power subframe so;
