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.read more

User terminal, radio base station and radio communication method
TL;DR: In this article, a radio base station non-orthogonal-multiplex downlink signals for a plurality of user terminals over a given radio resource, a user terminal having received the downlink signal for the plurality of users decodes the signal and reports a judgement result as to whether or not the signal has been successfully received.
