Abstract
A stochastic channel state information transmission/reception method and apparatus is provided for use in a multiuser radio communication system. The signal method of transmitting and receiving signals in a terminal in a mobile communication system according to the present disclosure includes receiving a reference signal transmitted by a base station, estimating channel information based on the reference signal, predicting a channel estimation error based on the channel information, generating feedback information based on the channel estimation error, and transmitting feedback information to the base station.
Claims20
A method for communication by a terminal in a mobile communication system, the method comprising:
- identifying first information on a resource for channel feedback information;
- receiving, from a base station, a first reference signal based on the first information;
- identifying second information on a channel based on the first reference signal;
- and
- transmitting, to the base station, channel feedback information based on the first information and the second information.
A method for communication by a base station in a mobile communication system, the method comprising:
- identifying first information on a resource for channel feedback information;
- transmitting, to a terminal, a first reference signal based on the first information;
- and
- receiving, from the terminal, channel feedback information based on the first information and second information on a channel, the second information being identified based on the first reference signal.
A terminal for communication in a mobile communication system, the terminal comprising:
- a transceiver configured to transmit and receive at least one signal;
- and
- a controller electrically coupled with the transceiver and configured to:
- identify first information on a resource for channel feedback information,
- receive, from a base station, a first reference signal based on the first information,
- identify second information on a channel based on the first reference signal, and
- transmit, to the base station, channel feedback information based on the first information and the second information.
A base station for communication in a mobile communication system, the base station comprising:
- a transceiver configured to transmit and receive at least one signal;
- and
- a controller electrically coupled with the transceiver and configured to:
- identify first information on a resource for channel feedback information,
- transmit, to a terminal, a first reference signal based on the first information, and
- receive, from the terminal, channel feedback information based on the first information and second information on a channel, the second information being identified based on the first reference signal.
