Abstract
The present invention proposes a method for preventing, when two types of subframes (first subframe and second subframe) exist in a wireless communication system, a high version terminal from performing unnecessary operation for the second subframe. Through the present invention, the high version terminal skips unnecessary operation, resulting in reduction of unnecessary power consumption.
Claims8
A method of operation of a terminal in a wireless communication system, the method comprising:
- receiving, at the terminal, system information including information associated with a sub-frame configuration of multimedia broadcast multicast service single frequency network (MBSFN) sub-frame;
- receiving, at the terminal, information on configuration of a transmission mode of the terminal, the transmission mode including one of a first transmission mode and a second transmission mode;
- identifying whether to detect a physical downlink control channel (PDCCH) in a first sub-frame of the MBSFN sub-frame based on the transmission mode of the terminal;
- if the transmission mode of the terminal is the first transmission mode, detecting at the terminal the PDCCH in a first sub-frame of the MBSFN sub-frame and a second sub-frame of non-MBSFN sub-frame for the terminal;
- and
- if the transmission mode of the terminal is the second transmission mode, detecting at the terminal the PDCCH in the second sub-frame of the non-MBSFN sub-frame.
A terminal for decoding a subframe in a wireless communication system, the terminal comprising:
- a transceiver for transmitting and receiving signals;
- and
- a controller coupled to the transceiver, the controller being configured to control the terminal to:
- receive system information including information associated with a sub-frame configuration of multimedia broadcast multicast service single frequency network (MBSFN) sub-frame,
- receive information on configuration of a transmission mode of the terminal, the transmission mode including one of a first transmission mode and a second transmission mode,
- identify whether to detect a physical downlink control channel (PDCCH) in a first sub-frame of the MBSFN sub-frame based on the transmission mode of the terminal,
- if the transmission mode of the terminal is the first transmission mode, detect the PDCCH in a first sub-frame of the MBSFN sub-frame and a second sub-frame of non-MBSFN sub-frame for the terminal, and
- if the transmission mode of the terminal is the second transmission mode, detect the PDCCH in the second sub-frame of the non-MBSFN sub-frame.
