Abstract
The present description relates to a method for controlling uplink power in a distributed multi-node system, comprising the following steps: receiving reference signals from a plurality of antenna nodes containing at least one antenna; estimating average propagation loss on the basis of the receiving power of the reference signals received from the plurality of antenna nodes; receiving, via a downlink control channel, noise and interference (NI) information from a base station which contains the plurality of antenna nodes; and determining uplink transmission power using the estimated average propagation loss and the received noise and interference information.
