Abstract
Methods and apparatus are provided for transmission and reception of common channel information in a mobile communication system using multi-antenna-based beamforming. A number of beams to be used for transmission to a terminal is determined at a base station. The common channel information is generated corresponding to the number of beams. The common channel information is transmitted from the base station to the terminal through one of the beams.
Claims20
A method for transmission of common channel information in a base station of a mobile communication system using multi-antenna-based beamforming, the method comprising the steps of:
- determining a number of beams to be used for transmission to a terminal;
- generating the common channel information corresponding to the number of beams;
- and
- transmitting the common channel information through one of the beams.
A method for receiving common channel information at a terminal in a mobile communication system using multi-antenna-based beamforming, the method comprising the steps of:
- receiving the common channel information transmitted by a base station;
- acquiring frame timing based on the common channel information;
- and
- processing a signal transmitted by the base station based on the frame timing,
- wherein the common channel information is generated based on a number of beams used by the base station, and the common channel information is transmitted through one of the beams.
A base station for transmitting common channel information in a mobile communication system using multi-antenna-based beamforming, the base station comprising:
- a transceiver configured to transmit and receive signals to and from a terminal;
- and
- a controller configured to determine a number of beams to be used for transmission to a terminal, generate the common channel information corresponding to the number of beams, and control the transceiver to transmit the common channel information through one of the beams.
A terminal for receiving common channel information in a mobile communication system using multi-antenna-based beamforming, the terminal comprising:
- a transceiver configured to transmit and receive signals to and from a base station;
- and
- a controller configured to control receiving the common channel information transmitted by a base station, acquire frame timing based on the common channel information, and process a signal transmitted by the base station based on the frame timing,
- wherein the common channel information is generated based on a number of beams used by the base station, and the common channel information is transmitted through one of the beams.
