Abstract:
An electronic device is provided. The electronic device includes a RFIC to convert data transmitted from the a communication processor into a RF signal and output the RF signal, and an antenna configured to receive the RF signal and radiate an electromagnetic field, the communication processor is configured to receive, from a BS, a reference signal for identifying a state of a downlink channel between the electronic device and the BS through the antenna and the RFIC, based on the reference signal and association information between the downlink channel and an uplink channel and between the electronic device and the BS, identify the uplink channel, based on the identified uplink channel, identify a precoder for the uplink channel, based on the identified precoder, precode uplink data and a DMRS, and transmit a signal based on the precoded data to the BS using at least some of the RFIC and the antenna.
