Communication resource allocation method, system, terminal and network side apparatus

Abstract

The embodiment of the invention provides a communication resource allocation method, a communication resource allocation system, a terminal and a network side apparatus. The communication resource allocation method comprises the following steps that: terminal equipment measures a current signal-to-leakage-and-noise ratio, a user packet to which the terminal equipment currently belongs can be determined through the current signal-to-leakage-and-noise ratio; when the user packet to which the terminal equipment currently belongs is a community center user packet, the terminal equipment receives information corresponding to a center user transmission band assigned by the network side apparatus, and is accessed to the center user transmission band, and performs uplink transmission on the center user transmission band through using transmitting power which is determined by a predetermined power control mode; and when the user packet to which the terminal equipment currently belongs is a community edge user packet, the terminal equipment receives information corresponding to an edge user transmission band assigned by the network side apparatus, and is accessed to the edge user transmission band, and performs uplink transmission on the edge user transmission band through using a transmitting power maximum allowable value. With the communication resource allocation method, the system, the terminal and the network side apparatus of the invention adopted, the suppression of co-channel interference can be realized in a heterogeneous network.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a communication resource allocation method, system, terminal and network side equipment. Background technique [0002] In the uplink of a wireless communication system, since users of different base stations share frequency bands, there is a phenomenon of co-frequency interference, that is, base stations deployed on the same frequency will interfere with each other, and any base station will receive signals from access The uplink interference of users in other cells, especially for users at the coverage edge of one cell or multiple cells, the uplink transmit power used is relatively large, so the resulting inter-cell interference is more serious. [0003] The current network is mainly divided into homogeneous network and heterogeneous network; heterogeneous network architecture refers to the deployment of one or more micro cell base stations with low transm...

Problems solved by technology

[0005] However, in a heterogeneous network, due to the denser deployment of cells in a heterogeneous network, the distance between a user and the interfered cell is closer, and the uplink interference problem in a heterogeneous network is more serious than in a traditional homogeneous network

In a heterogeneous network, since some micro cells with low power and small coverage may be randomly distributed inside the macro base station, if a user located at the edge of the macro cell increases the transmission power, since there is a micro cell coverage nearby, it will affect the micro cell The uplink user signal received in the medium produces obvious interference, which affects the user performance within the coverage area of ​​the micro cell

It can be seen that the method of suppressing co-channel interference by controlling the uplink power used in the existing homogeneous network is not suitable for heterogeneous networks, so a co-channel interference suitable for both homogeneous and heterogeneous networks is provided Suppression schemes, realizing co-channel interference suppression in communication networks has become an urgent problem to be solved by those skilled in the art
