Description

The transmission of channel quality measurement indication signaling and method of reseptance
Technical field
The present invention relates to wireless communication technology field, the transmission and the method for reseptance of channel quality measurement indication signaling in particularly a kind of wireless communication system.
Background technology
In wireless communication system, the base station is meant the equipment that service is provided for terminal, and the base station communicates by Uplink/Downlink and terminal, and descending or forward direction is meant that the base station arrives the direction of terminal, and is up or oppositely be meant the direction of terminal to base station.A plurality of terminals can send data by up link to the base station simultaneously, also can receive data simultaneously from the base station by down link.
Adopt in the data transmission system of base station scheduling control, the scheduling of all resources of system distributes to be undertaken by the base station usually, for example, the resource situation that can use when resource allocation conditions when downlink transfer is carried out in the base station and terminal are carried out uplink etc., these are all distributed by base station scheduling.
In ofdm system, when base station and different terminals carry out downlink data transmission in the same sub-district,, therefore can avoid disturbing in the sub-district because these down links are orthogonal.Yet the down link between the different districts may not be a quadrature, so each terminal all may be subjected to the descending interference from other neighbor cell base station, i.e. presence of intercell interference.
The reduction presence of intercell interference is an important goal of cellular system design to the influence of systematic function, if the serious interference of minizone, then the transmittability of power system capacity, particularly Cell Edge User be can reduce, and then the covering power of system and the performance of terminal influenced.In order to overcome presence of intercell interference, can adopt fractional frequency reuse technology (FractionalFrequency Reuse abbreviates FFR as), give corresponding terminal with other resource allocation of different sub carrier power stage, to reduce presence of intercell interference intensity.
Fig. 1 is frequency resource allocation mode and each frequency partition (Frequency Partition, the schematic diagram of transmission power limit situation FP) of adjacent three sectors.The cardinal principle of FFR is:
At first, available frequency resources is divided into the individual FP of N (N is the integer greater than zero), supposes N=4, be about to available frequency resources and be divided into [FP 1, FP 2, FP 3, FP 4].Wherein, FP 2, FP 3, FP 4Frequency re-use factor be 3 (they are Reuse3, are also referred to as Reuse1/3), FP 2, FP 3, FP 4In frequency resource allocation give sector in three adjacent sectors, and this frequency resource can not be used in other two sectors or need to adopt the method for the subcarrier transmitting power that limits this frequency resource to use this frequency resource; FP 1Frequency re-use factor is 1 (being Reuse1), and three adjacent sectors can use this frequency resource.
Then, each terminal is by measuring the channel quality (for example, the average signal of each FP and interference and noise ratio SINR, or the interference measure of each FP) of each FP, arrives the base station to the channel quality information of the individual FP of base station feedback M (M 〉=1).
At last, the base station is the terminal distribution resource according to the channel quality information situation of the FP of terminal to report.
When a plurality of terminals all report the channel quality information of identical FP, because the resource-constrained of FP, some terminals can not be assigned with the resource of this FP, and then the channel quality information of these terminals on other FP need be known in the base station, could be the resource on other FP that are fit to of these terminal distribution.
