摘要
The present invention relates to the field of communications, and in particular to a method and apparatus of uplink interference coordination in a heterogeneous network. The method includes: monitoring uplink channel quality of terminal equipment; acquiring an uplink almost blank subframe when uplink interference appears, with terminal equipment in a Macro cell in the uplink almost blank subframe transmitting at reduced transmission power or no transmission power; and scheduling the terminal equipment subjected to uplink interference on the uplink almost blank subframe to perform uplink communication. With the embodiments of the present invention, interference brought by the uplink data transmission of the terminal equipment of the Macro cell to the uplink reception of the terminal equipment of the Pico cell may be avoided, thereby ensuring the uplink channel quality of the terminal equipment in the Pico cell.
