Embodiment Construction

[0047]An embodiment of the present invention provides a subcarrier allocation method, which is used to improve the utilization efficiency of a micro base station in a heterogeneous communication network. Embodiments of the present invention also provide related devices, which will be described respectively below.

[0048] For a schematic diagram of the basic architecture of a heterogeneous communication network, please refer to figure 1 , different from the traditional homogeneous communication network, each cell of the heterogeneous communication network includes a macro base station and multiple micro base stations. have a discussion. The entire heterogeneous communication network includes S base stations. Wherein, each base station of the heterogeneous communication network is configured to include M subcarriers, and the entire heterogeneous communication network includes S×M subcarriers. And in the S base stations, the frequency band ranges of the mth subcarriers of all...

Abstract

The invention discloses a subcarrier distribution method used for improving the throughput of a heterogeneous communication network. The method comprises that each base station determines the channel coefficient of each subcarrier to each subscriber; the data transmission speed of each subcarrier to each subscriber is determined according to the channel coefficient; and subcarriers of the S base stations are distributed to the N subscribers according to the data transmission speed. The invention also provides a related subcarrier distribution device and the base station.

Description

technical field [0001] The present invention relates to the communication field, in particular to a subcarrier allocation method, a related device and a base station. Background technique [0002] Heterogeneous communication network is a new type of network structure different from the traditional network architecture. It deploys various types of low-power and low-processing micro-cell base stations (hereinafter referred to as macro-cell base stations) in the coverage area of ​​traditional macro-cell base stations (hereinafter referred to as macro-cell base stations). Referred to as micro base station), it is used to eliminate the coverage "blind area" and "busy area" of traditional macro base station, which can greatly improve the coverage area and the spectral efficiency of the unit area in theory. [0003] Throughput refers to the amount of data transmitted by the communication network per unit time. Under the premise of a certain structure of the communication network, t...
