Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of receiving/transmission method and device of resource metric.
Background technology
In wireless communication system, base station refers to the equipment that service is provided for terminal, and base station communicates by Uplink/Downlink and terminal, and descending or forward direction refers to that base station arrives the direction of terminal, up or oppositely refer to the direction of terminal to base station.A plurality of terminals can send data by up link to base station simultaneously, also can receive data from base station by down link simultaneously.
Adopt in the data transmission system of base station scheduling control, the dispatching distribution of all resources of system is undertaken by base station usually, for example, the resource situation that can use when resource allocation conditions when downlink transfer is carried out in base station and terminal are carried out uplink etc., these are all distributed by base station scheduling.
At OFDM (Orthogonal Frequency Division Multiplexing, orthogonal frequency division multiplexi) in system, when in same community, base station and different terminals carry out downlink data transmission, because these down links are orthogonal, therefore can avoid disturbing in community.Yet the down link between different districts may not be quadrature, so each terminal may be subject 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 on the impact of systematic function, if the serious interference of minizone, 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 affected.In order to overcome presence of intercell interference, can adopt AFR (Adaptive Frequency Reuse, adaptive frequency reuse) scheme, the different sub-band resource is distributed to terminal, to reduce presence of intercell interference intensity.
As shown in Figure 1, be the schematic diagram of the transmission power limit situation of the frequency resource allocation mode of adjacent sectors and each FP (Frequency Partition, frequency partition).The cardinal principle of AFR scheme is:
At first, available frequency resources is divided into to N FP, N is greater than zero integer, supposes N=7, is about to available frequency resources and is divided into [FP

Then, a RM (Resource Metric, resource metric), i.e. [RM are distributed for each FP in base station

iThe CQI (Channel Quality Information, channel quality information) of the maximum individual FP of M (M is more than or equal to 1) is to base station, and the resource distribution is carried out according to the CQI situation of the FP of terminal to report in base station.
Finally, the base station self adaptation is adjusted the size of each FP, the transmitting power of each FP sub-carriers and the RM value of each FP, and notifies all terminals in this sector.Yet, if base station all sends to terminal by the RM of all FP at every turn, can obviously increase the expense of system.
