Abstract
Methods and apparatuses for adapting a bandwidth of a terminal in a wireless communication system are provided. The method includes transmitting, to a base station (BS), information about bandwidth adaptation capability of the terminal, receiving, from the BS, a bandwidth adaptation command for requesting adaptation to a bandwidth corresponding to the bandwidth adaptation capability of the terminal, and adapting the bandwidth of the terminal in at least one symbol location in a unit time period of a subframe, based on the received bandwidth adaptation command.
Claims19
A method, performed by a terminal, of adapting a bandwidth for transmitting and receiving signals, the method comprising:
- transmitting, to a base station (BS), information about bandwidth adaptation capability of the terminal;
- receiving, from the BS, a bandwidth adaptation command for requesting adaptation to a bandwidth corresponding to the bandwidth adaptation capability of the terminal;
- and
- adapting the bandwidth of the terminal in at least one symbol location in a unit time period of a subframe based on the bandwidth adaptation command.
A method, performed by a base station (BS), of adapting a bandwidth for transmitting and receiving signals to and from a terminal, the method comprising:
- receiving information about bandwidth adaptation capability of the terminal;
- determining a bandwidth corresponding to the bandwidth adaptation capability of the terminal based on the information about the bandwidth adaptation capability of the terminal;
- and
- transmitting, to the terminal, a bandwidth adaptation command for requesting adaptation to the bandwidth determined by the BS.
A terminal for adapting a bandwidth for transmitting and receiving signals, the terminal comprising:
- a transceiver configured to:
- transmit, to a base station (BS), information about bandwidth adaptation capability of the terminal, and
- receive, from the BS, a bandwidth adaptation command for requesting adaptation to a bandwidth corresponding to the bandwidth adaptation capability of the terminal;
- a memory configured to store the information about the bandwidth adaptation capability of the terminal;
- and
- at least one processor configured to adapt the bandwidth of the terminal in at least one symbol location in a unit time period of a subframe based on the bandwidth adaptation command.
A base station (BS) for adapting a bandwidth for transmitting and receiving signals to and from a terminal, the BS comprising:
- a transceiver configured to receive information about bandwidth adaptation capability of the terminal;
- a memory configured to store the information about the bandwidth adaptation capability of the terminal;
- and
- at least one processor configured to determine a bandwidth corresponding to the bandwidth adaptation capability of the terminal based on the information about the bandwidth adaptation capability of the terminal,
- wherein the transceiver is further configured to transmit, to the terminal, a bandwidth adaptation command for requesting adaptation to the bandwidth determined by the BS.
