Abstract
The present invention relates to a wireless communication system. A method for a terminal reporting channel state information in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: receiving, from a second cell interfering with communication between a first cell and the terminal, a second precoding matrix indicator (PMI) determined based on the interference; and transmitting, to the first cell, the second PMI and a channel quality indicator (CQI).
Claims14
A method of reporting a channel state information (CSI) by a user equipment in a wireless communication system, the method comprising:
- receiving, from a 2nd cell causing interference to communication between a 1st cell and the user equipment, a 2nd PMI (precoding matrix indicator) determined based on the interference;
- and
- transmitting the 2nd PMI and a CQI (channel quality indicator) to the 1st cell.
A user equipment for reporting a channel state information (CSI) in a wireless communication system, a user equipment comprising:
- a radio frequency (RF) unit;
- and
- a processor,
- wherein the processor is configured:
- to receive, from a 2nd cell causing interference to communication between a 1st cell and the user equipment, a 2nd PMI (precoding matrix indicator) determined based on the interference,
- to transmit the 2nd PMI and a CQI (channel quality indicator) to the 1st cell.
