Method and apparatus for transmitting uplink control signal in wireless cellular communication system

A method of receiving reference signal by a terminal in a wireless communication system, the method comprising:

• receiving, from a base station, a message configuring a channel state information reference signal (CSI-RS) resource;
• determining a resource for a CSI-RS based on the message, the resource including at least one reference signal (RS) group;
• and
• receiving, from the base station, the CSI-RS on the determined resource,
• wherein each of the at least one RS group includes two resource elements (REs) adjacent on a frequency axis.

A terminal of receiving reference signal in a wireless communication system, the terminal comprising:

• a transceiver configured to transmit and receive signals;
• and
• a controller configured to:
• receive, from a base station, a message configuring a channel state information reference signal (CSI-RS) resource,
• determine a resource for a CSI-RS based on the message, the resource including at least one reference signal (RS) group, and
• receive, from the base station, the CSI-RS on the determined resource,
• wherein each of the at least one RS group includes two resource elements (REs) adjacent on a frequency axis.

A method of transmitting reference signal by a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, a message configuring a channel state information reference signal (CSI-RS) resource;
• identifying a resource for a CSI-RS based on the message, the resource including at least one reference signal (RS) group;
• and
• transmitting, to the terminal, the CSI-RS on the determined resource,
• wherein each of the at least one RS group includes two resource elements (REs) adjacent on a frequency axis.
