Abstract

A method and base station in a wireless communication system are provided. The method includes transmitting, to a terminal, system information including information associated with a sub-frame configuration of multimedia broadcast multicast service single frequency network (MBSFN) sub-frames, identifying whether the transmission mode of the terminal is a first transmission mode or a second transmission mode, transmitting, to the terminal, dedicated message including configuration information of the identified transmission mode of the terminal, transmitting, to the terminal, control information in a physical downlink control channel (PDCCH) and data in a physical downlink shared channel (PDSCH) in a first sub-frame of the MBSFN sub-frames, if the terminal is configured in the first transmission mode, and transmitting, to the terminal, the control information in the PDCCH and the data in the PDSCH in a second sub-frame of a non-MBSFN sub-frames, if the terminal is configured in the second transmission mode.

Claims

1. A method by 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 a multimedia broadcast multicast service single frequency network (MBSFN) sub-frame;

receiving, at the terminal, a dedicated message including information on a configuration of a transmission mode of the terminal;

detecting a physical downlink control channel (PDCCH) in a sub-frame of a non-MBSFN sub-frame and decoding a physical downlink shared channel (PDSCH) in the sub-frame of the non-MBSFN sub-frame;

identifying whether the transmission mode of the terminal is a first transmission mode based on the received information on the configuration of the transmission mode of the terminal; and

if the transmission mode of the terminal is identified as the first transmission mode, detecting a PDCCH in a sub-frame of the MBSFN sub-frame.

2. The method of claim 1, further comprising:

decoding a PDSCH in the sub-frame of the MBSFN sub-frame if the transmission mode of the terminal is identified as the first transmission mode.

3. The method of claim 1, further comprising:

if the transmission mode of the terminal is not identified as the first transmission mode, skipping detection of the PDCCH in the MBSFN sub-frame.

4. The method of claim 1, wherein the dedicated message is included in a radio resource control (RRC) message.

5. The method of claim 1,

wherein the terminal supports receiving the PDSCH over the MBSFN sub-frame, if the terminal is configured in the first transmission mode.

6. The method of claim 1,

wherein the first transmission mode supports Rel-10, and wherein the Rel-10 allows transmitting the PDSCH in the MBSFN sub-fame.

7. The method of claim 1,

wherein the first transmission mode is a mode wherein the PDSCH over the MBSFN subframe is supported, and

wherein a second transmission mode is a mode wherein the PDSCH over the MBSFN subframe is not supported.

8. A terminal in a wireless communication system, the terminal comprising:

a transceiver for transmitting and receiving signals; and

a controller configured to;

receive, via the transceiver, system information including information associated with a sub-frame configuration of a multimedia broadcast multicast service single frequency network (MBSFN) sub-frame,

receive, via the transceiver, a dedicated message including information on a configuration of a transmission mode of the terminal,

detect a physical downlink control channel (PDCCH) in a sub-frame of a non-MBSFN sub-frame and decoding a physical downlink shared channel (PDSCH) in the sub-frame of the non-MBSFN sub-frame,

identify whether the transmission mode of the terminal is a first transmission mode based on the received information on the configuration of the transmission mode of the terminal, and

if the transmission mode of the terminal is identified as the first transmission mode, detect a PDCCH in a sub-frame of the MBSFN sub-frame.

9. The terminal of claim 8, wherein the transceiver is further configured to decode a PDSCH in the sub-frame of the MBSFN sub-frame if the transmission mode of the terminal is identified as the first transmission mode.

10. The terminal of claim 8, wherein the controller is further configured to:

skip, if the transmission mode of the terminal is not identified as the first transmission mode, detection of the PDCCH in the MBSFN sub-frame.

11. The terminal of claim 8, wherein the dedicated message is included in a radio resource control (RRC) message.

12. The terminal of claim 8, wherein the terminal supports receiving the PDSCH over the MBSFN sub-frame, if the terminal is configured in the first transmission mode.

13. The terminal of claim 8,

wherein the first transmission mode supports Rel-10, and

wherein the Rel-10 allows transmitting the PDSCH in the MBSFN sub-fame.

14. The terminal of claim 8,

wherein the first transmission mode is a mode wherein the PDSCH over the MBSFN subframe is supported, and

wherein a second transmission mode is a mode wherein PDSCH over the MBSFN subframe is not supported.
