METHOD AND DEVICE FOR DETERMINING REFERENCE SIGNAL ANTENNA PORT FOR DOWNLINK CONTROL CHANNEL IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a method of transmitting a downlink control channel including one or more control channel elements to a terminal by a base station in a wireless communication system. In particular, the method includes: allocating an antenna port of a demodulation-reference signal (DM-RS) to the one or more control channel elements that configure the downlink control channel; and transmitting the downlink control channel to the terminal by using the DM-RS of the allocated antenna port, wherein the antenna port of the DM-RS is determined on the basis of the number of control channel elements per resource block.

1. A method for transmitting a downlink control channel comprised of at least one control channel element to a user equipment (UE) at a base station in a wireless communication system, the method comprising:
allocating an antenna port for a demodulation reference signal (DM-RS) to the at least one control channel element; and transmitting the downlink control channel to the UE using the DM-RS of the antenna port, wherein the antenna port is determined based on a number of control channel elements per resource block.
