The invention discloses a method and a device for allocating member carrier waves. The method comprises steps of calculating and acquiring carrier wave selection?parameters when a user uses the member carrier waves, sending the carrier wave selection?parameters to a corresponding base station, allocating member carrier waves according to the acquired carrier wave selection?parameters by each base station and sending data to the user in the allocated member carrier waves. According to the method and the device for allocating member carrier waves, each base station can dynamically allocate member carrier waves according to the carrier wave selection?parameters when each user uses each member carrier wave, interference of the member carrier wave on the adjacent base station is reduced in the condition of high frequency band use, the problem of low frequency reuse?efficiency when frequency domain interference in a heterogeneous network is avoided through member carrier wave selection in the prior art is solved, and effects of high frequency band reuse?efficiency and high working efficiency of allocated carrier waves when frequency domain interference is avoided in the heterogeneous network are realized.
Description
technical field [0001] The present invention relates to the field of communications, in particular to a method and device for allocating component carriers. Background technique [0002] The heterogeneous network is mainly realized by improving the topology of the network. It is composed of high-power macro base stations planned by the network and low-power nodes with autonomous placement characteristics under its coverage. Among them, low-power nodes include femtocells, picocells, and relay stations. Through these low-power nodes, hotspot area coverage, base station business offload, and base station split gain can be achieved. Although the heterogeneous network can optimize the performance of the system, due to the different power and coverage of different types of base stations in the heterogeneous network, and the independent placement of low-power nodes, the interference of control channels and traffic channels between different base stations is very prominent. Therefo...
