Method for transmitting and receiving control information in a wireless communication system, and apparatus for same

摘要

Disclosed are a method for transmitting and receiving control information in a wireless communication system, and an apparatus for same. A method for transmitting control information by a base station in a wireless communication system according to the present invention comprises the steps of: performing a precoding process by applying different precoding matrix indices to control information for each terminal among predetermined precoding matrices; and transmitting, to each terminal, the precoded control information to which different precoding matrix indices are applied for each terminal, wherein said control information is multiplexed and transmitted via a plurality of antennas.

主权项

1. A method for transmitting control information by a base station to a number of user equipment (UE) in a wireless communication system, the method comprising:
precoding control information by applying different precoding matrix indices to the control information per each UE from among predetermined precoding matrices; and transmitting, to each UE through a beamformed Physical Downlink Control CHannel (bfPDCCH), the precoded control information to which the different precoding matrix indices are applied for each UE, wherein the control information is multiplexed and transmitted via a plurality of antennas, and wherein the precoding matrix indices applied to the control information are implicitly signaled to each UE for blinding decoding of the precoded control information by using a previous Physical Downlink Shared CHannel (PDSCH) transmission.
