Abstract
Methods and apparatus are provided for transmitting a reference signal by a base station in a mobile communication system. The method includes generating, at the base station, information for a non zero transmission power reference signal including at least one resource element; generating, at the base station, bitmap information indicating a zero transmission power reference signal; and transmitting, at the base station, the information for the non zero transmission power reference signal and the bitmap information to a terminal.

A method for transmitting a reference signal by a base station in a mobile communication system, the method comprising:
- generating, at the base station, information on a non zero transmission power reference signal including at least one resource element;
- generating, at the base station, bitmap information on a zero transmission power reference signal, wherein the bitmap information indicates one of predefined patterns of resource elements for the zero transmission power reference signal;
- and
- transmitting, at the base station, the information on the non zero transmission power reference signal and the bitmap information to a terminal.
A base station for transmitting reference signals in a mobile communication system, the base station comprising:
- a transceiver;
- and
- a controller configured to:
- generate information on a non zero transmission power reference signal including at least one resource element,
- generate bitmap information on a zero transmission power reference, wherein the bitmap information indicates one of predefined patterns of resource elements for the zero transmission power reference signal, and
- control the transceiver to transmit the information on the non zero transmission power reference signal and the bitmap information to a terminal.
A method for processing a reference signal transmitted by a base station in a mobile communication system, the method comprising:
- receiving, at a terminal, information on a non zero transmission power reference signal, from the base station, wherein the reference signal includes at least one resource element;
- receiving a bitmap information on a zero transmission power reference signal, wherein the bitmap information indicates one of predefined patterns of resource elements for the zero transmission power reference signal;
- and
- processing the non zero transmission power reference signal and the zero transmission power reference signal according to the information on the non zero transmission power reference signal and the bitmap information.
A terminal for processing a reference signal transmitted by a base station in a mobile communication system, the terminal comprising:
- a transceiver;
- and
- a controller configured to:
- control the transceiver to receive information on a non zero transmission power reference signal comprising at least one resource element and to receive bitmap information on a zero transmission power reference signal, wherein the bitmap information indicates one of predefined patterns of resource elements for the zero transmission power reference signal, and
- process the non zero transmission power reference signal and the zero transmission power reference signal according to the information on the non zero transmission power reference signal and the bitmap information.
