Abstract
Methods and apparatus are provided for transmitting processing reference signals in a mobile communication system. A base station determines a reference signal pattern comprising at least one resource element, generates a bitmap indicator indicating whether zero transmission power is assigned to the at least one resource element of the reference signal pattern, and transmits the reference signal pattern and the bitmap indicator to a terminal. The terminal receives the reference signal pattern and the bitmap indicator, and processes a reference signal extracted according to the reference signal pattern and the bitmap indicator.
Claims20
A method for transmitting at least one reference signal of a base station in a mobile communication system, comprising the steps of:
- determining, at the base station, a non-zero transmission power reference signal configuration among a first plurality of reference signal configurations, wherein the non-zero transmission power reference signal configuration comprises at least one resource element;
- generating, at the base station, a bitmap indicator indicating a zero transmission power reference signal configuration among a second plurality of reference signal configurations;
- and
- transmitting information for the non-zero transmission power reference signal configuration and the bitmap indicator from the base station to a terminal.
A base station for transmitting at least one reference signal in a mobile communication system, comprising:
- a reference signal determiner that determines a non-zero transmission power reference signal configuration among a first plurality of reference signal configurations, wherein the non-zero transmission power reference signal configuration comprises at least one resource element;
- a reference signal muting determiner configured to generate a bitmap indicator indicating a zero transmission power reference signal configuration among a second plurality of reference signal configurations;
- and
- a transceiver configured to transmit information for the non-zero transmission power reference signal configuration and the bitmap indicator to a terminal.
A method for processing at least one reference signal transmitted by a base station in a mobile communication system, comprising the steps of:
- receiving, at a terminal, information for a non-zero transmission power reference signal configuration among a first plurality of reference signal configurations from the base station, wherein the non-zero transmission power reference signal configuration comprises at least one resource element;
- receiving a bitmap indicator indicating a zero transmission power reference signal configuration among a second plurality of reference signal configurations;
- and
- processing the at least one reference signal extracted according to information for the non-zero transmission power reference signal configuration and the bitmap indicator.
A terminal for processing at least one reference signal transmitted by a base station in a mobile communication system, comprising:
- a transceiver configured to communicate signals with the base station;
- and
- a controller configured to control the transceiver to receive information for a non-zero transmission power reference signal configuration among a first plurality of reference signal configurations, wherein the non-zero transmission power reference signal configuration comprises at least one resource element, and a bitmap indicator indicating a zero transmission power reference signal configuration among a second plurality of reference signal configurations, and to process the at least one reference signal extracted according to the information for the non-zero transmission power reference signal configuration and the bitmap indicator.
