METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING CONTROL CHANNEL IN WIRELESS COMMUNICATION SYSTEM

摘要

A control channel transmission/reception method and an apparatus for transmitting/receiving control channels using a resource allocation scheme applicable regardless of reference signal transmission or whether the reference signal is transmitted in distributed transmission mode or localized transmission mode are provided. The control channel transmission method includes mapping a Demodulation Reference Signal (DMRS) to Resource Elements (REs) of a Resource Block (RB) for transmitting a control channel, mapping the control channel to the REs numbered with numbers of predetermined number of Resource Element Groups (REGs) in a frequency-first ascending order cyclically, with the exception of the REs to which the DMRS is mapped, and transmitting the DMRS and the control channel.

1. A method for transmitting a plurality of control information by a base station in a wireless communication system, the method comprising:
mapping a reference signal for demodulating the plurality of control information to first resource elements (REs) of a resource block (RB); mapping the plurality of control information to second REs except the first REs carrying the reference signal; and transmitting the reference signal via the first REs and the plurality of control information via the second REs; wherein the second REs are associated with cyclical index in an order of frequency-first.
