  "abstract": "A method for and apparatus for supporting transmission efficiency in a wireless communication system is provided. A wireless device determines a message type based on information, the message type indicating a plurality of transmission types; and performs adaptive measurement, data process, and power control according to the message type. Herein the information indicates one of the plurality of candidate message types that are predefined or are defined by a RRC message.",
  "claims": [
    "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."

  "description_excerpt": "This application is a 35 USC §371 National Stage entry of International Application No. PCT/KR2013/011575 filed on Dec. 13, 2013, and claims priority to U.S. Provisional Application No. 61/737,103 filed on Dec. 14, 2012, all of which are hereby incorporated by reference in their entireties as if fully set forth herein.\n\nThe present invention relates to wireless communications, and more particularly, to a method and apparatus for supporting transmission efficiency in a wireless communication system consisting of multiple carriers over single frequency or multiple frequencies.\n\n3rd generation partnership project (3GPP) long term evolution (LTE) is an improved version of a universal mobile telecommunication system (UMTS) and a 3GPP release 8. The 3GPP LTE uses orthogonal frequency division multiple access (OFDMA) in a downlink, and uses single carrier-frequency division multiple access (SC-FDMA) in an uplink. The 3GPP LTE employs multiple input multiple output (MIMO) having up to four antennas. In recent years, there is an ongoing discussion on 3GPP LTE-advanced (LTE-A) that is an evolution of the 3GPP LTE.\n\nThe commercialization of the 3GPP LTE (A) system is being recently accelerated. The LTE systems are spread more quickly as respond to users demand for services that may support higher quality and higher capacity while ensuring mobility, as well as voice services. The LTE system provides for low transmission delay, high transmission rate and system capacity, and enhanced coverage.",
