Abstract
Methods and apparatuses for transmitting and receiving a signal in a mobile communication system are provided. The method for receiving a signal at a User Equipment (UE) in the mobile communication system includes receiving, from a Base Station (BS), configuration information indicating whether a Broadcasting Channel (BCH) and a Synchronization Channel (SCH) are allocated in at least one subband; receiving, from the BS, a downlink control channel; and receiving, from the BS, a downlink data channel, based on the configuration information and the downlink control channel.
Claims16
A method for receiving a signal at a terminal in a mobile communication system, the method comprising:
- receiving, from a base station, configuration information indicating whether a broadcasting channel (BCH) for transmitting system information and a synchronization channel (SCH) for transmitting synchronization information are allocated in at least one subband;
- receiving, from the base station, control information on a downlink control channel;
- and
- receiving, from the base station, downlink data on a downlink data channel of a subband among the at least one subband based on the control information, the downlink data channel of the subband being identified based on the configuration information.
A method for transmitting a signal at a base station in a mobile communication system, the method comprising:
- transmitting, to a terminal, configuration information indicating whether a broadcasting channel (BCH) for transmitting system information and a synchronization channel (SCH) for transmitting synchronization information are allocated in at least one subband;
- transmitting, to the terminal, control information on a downlink control channel;
- and
- transmitting, to the terminal, downlink data on a downlink data channel of a subband among the at least one subband;
- based on the control information, the downlink data channel of the subband being identified based on the configuration information.
A terminal of a mobile communication system, the terminal comprising:
- a transceiver which transmits and receives signals to and from a base station;
- and
- a control unit configured to receive, from a base station, configuration information indicating whether a broadcasting channel (BCH) for transmitting system information and a synchronization channel (SCH) for transmitting synchronization information are allocated in at least one subband, to receive, from the base station, control information on a downlink control channel, and to receive downlink data on a downlink data channel of a subband among the at least one subband based on the control information, the downlink data channel of the subband being identified based on the configuration information.
A base station of a mobile communication system, the base station comprising:
- a transceiver which transmits and receives signals to and from a terminal;
- and
- a control unit configured to transmit, to a terminal, configuration information indicating whether a broadcasting channel (BCH) for transmitting system information and a synchronization channel (SCH) for transmitting synchronization information are allocated in at least one subband, to transmit, to the terminal, control information on a downlink control channel to the terminal, and to transmit, to the terminal, downlink data on a downlink data channel of a subband among the at least one subband based on the control information, the downlink data channel of the subband being identified based on based on the configuration information and the control information.
