Method and apparatus for supporting transmission efficiency in a wireless communication system

1. A method for supporting transmission efficiency in a wireless communication system, the method comprising:

transmitting, by a user equipment (UE), capability information including a Quality of Service (QoS) requirement to an eNodeB (eNB);

receiving, by the UE, message type indicator index (MTII) information indicating a behavior type of the UE,

wherein the MTII information is received in response to the QoS requirement from the eNB, and

wherein the behavior type includes first information on whether a channel state information (CSI) measurement is enabled, second information on whether a hybrid automatic repeat request (HARQ) is set, third information on whether an automatic adaptation for a modulation coding scheme (MCS) is enabled, fourth information on whether a boosting for the MCS is enabled, and fifth information on whether a power boosting for the power control is enabled; and

performing, by the UE, adaptive measurement, data process, and power control according to the MTII information.

2. The method of claim 1 , wherein the MTII information indicates one of a plurality of candidate behavior types that are predefined or are defined by a RRC message.

3. The method of claim 1 , wherein the MTII information is received in a Downlink Control Information (DCI) on a control channel, the MTII information including an indicator indicating the behavior type.

4. The method of claim 1 , wherein the MTII information is obtained from a radio network temporary identifier (RNTI) by which a control channel is detected, the RNTI indicating the behavior type.

5. The method of claim 1 , wherein the MTII information includes a HARQ process ID that corresponds to the behavior type.

6. The method of claim 1 , wherein the MTII information includes a set of enhanced Physical Downlink Control Channels (ePDCCHs) that corresponds to the behavior type.

7. The method of claim 1 , wherein the MTII information includes an aggregation level (AL) that corresponds to the behavior type.

8. The method of claim 1 , wherein the MTII information includes a Resource Block (RB) index, or a set of subframes that corresponds to the behavior type.

9. The method of claim 1 , wherein the MTII information is received by a Semi-Persistent Scheduling (SPS) configuration.

10. A wireless device that supports transmission efficiency in a wireless communication system, the wireless device comprising:

a radio frequency (RF) unit that receives and transmits a radio signal; and

a processor operatively coupled with the RF unit, that:

controls the RF unit to transmit capability information including a Quality of Service (QoS) requirement to an eNodeB (eNB);

controls the RF unit to receive message type indicator index (MTII) information indicating a behavior type of the UE,

wherein the MTII information is received in response to the QoS requirement from the eNB, and

wherein the behavior type includes first information on whether a channel state information (CSI) measurement is enabled, second information on whether a hybrid automatic repeat request (HARQ) is set, third information on whether an automatic adaptation for a modulation coding scheme (MCS) is enabled, fourth information on whether a boosting for the MCS is enabled, and fifth information on whether a power boosting for the power control is enabled; and

performs adaptive measurement, data process, and power control according to the MTII information.

11. A method for supporting transmission efficiency in a wireless communication system, the method comprising:

receiving, by a non-legacy user equipment (UE), a monitoring configuration frame from an eNodeB (eNB), wherein the monitoring configuration frame includes information on a cell radio network temporary identifier (C-RNTI) of a legacy UE for detecting the legacy UE;

overhearing, by the non-legacy UE, data and control which are transmitted to the legacy UE based on the information on the C-RNTI; and

transmitting, by the non-legacy UE, a response frame to the eNB, wherein the response frame includes acknowledge (ACK) information on the data and the control and the C-RNTI which is overheard successfully.

12. The method of claim 1 , wherein the MTII information is generated by the eNB based on the QoS requirement, and wherein the capability information further includes a battery power requirement, processing power requirement, and buffer size requirement.
