Signal transmission method and system for transmitting signal by using interference control method and/or transmission power control method

摘要

Provided are a signal transmission method and a network apparatus to control interference in a radio communication network. A terminal may transmit to the network apparatus, signal quality information associated with a radio channel formed between the terminal and a corresponding base station. The corresponding base station may output a signal received by the plurality of terminals, based on the signal quality information.

主权项

1. A terminal comprising:
a receiver configured to receive a main signal transmitted from a corresponding base station, and receive interference signals transmitted from interference base stations, the interference signals being processed based on an interference control scheme; and a signal quality information generation unit configured to generate signal quality information to be transmitted to the corresponding base station and the interference base station, the signal quality information enabling the interference base stations to control phases of the transmitted interference signals to have a same phase when received by the receiver.
