Method and apparatus for transmitting and receiving data
The prevent invention relates to a method and apparatus for transmitting and receiving data. The method for receiving control data by a terminal can include the steps of: a terminal receiving redundant information on a first control channel from a base station; the terminal receiving a first subframe from the base station and first blind decoding being performed on the first subframe in order to monitor the first control channel; the terminal receiving a second subframe from the base station and second blind decoding being performed on the second subframe on the basis of the redundant information and the first blind decoding information in order to monitor a second control channel.
1. A method of receiving a downlink control channel in a wireless communication system, the method performed by a user equipment (UE) and comprising:
receiving a radio resource control (RRC) signal including first information from a base station (BS); and
performing blind decoding in a plurality of downlink sub-frames over which downlink control information (DCI) is repeated,
wherein the first information indicates a repetition number of the DCI over the plurality of downlink sub-frames,
wherein the DCI includes second information related to a repetition number of a physical uplink shared channel (PUSCH), and
wherein the DCI further includes a modulation and coding scheme (MCS) field indicating a MCS index value of a maximum of 10 for the UE.
2. The method of claim 1 , further comprising transmitting the PUSCH repeated over a plurality of uplink subframes based on the second information.
3. The method of claim 1 , wherein performing the blind decoding comprises:
performing first blind decoding on a first downlink sub-frame among the plurality of downlink sub-frames; and
performing second blind decoding on a second downlink sub-frame among the plurality of downlink sub-frames.
4. The method of claim 3 , further comprising determining a control channel element (CCE) aggregation level for transmitting a downlink control channel,
wherein the second blind decoding is performed based on the CCE aggregation level.
5. The method of claim 3 , further comprising determining a first control channel element (CCE) region in the first downlink sub-frame,
wherein the second blind decoding is performed on a second CCE region of the second downlink sub-frame, the second CCE region indicating a same resource allocation region as the first CCE region.
6. A user equipment (UE) receiving a downlink control channel in a wireless communication system, the UE comprising:
a radio frequency (RF) unit configured to receive information; and
a processor configured to:
receive a radio resource control (RRC) signal including first information from a base station (BS); and
perform blind decoding in a plurality of downlink sub-frames over which downlink control information (DCI) is repeated,
wherein the first information indicates a repetition number of the DCI over the plurality of downlink sub-frames,
wherein the DCI includes second information related to a repetition number of a physical uplink shared channel (PUSCH), and
wherein the DCI further includes a modulation and coding scheme (MCS) field indicating a MCS index value of a maximum of 10 for the UE.
7. The UE of claim 6 , wherein the processor is further configured to transmit the PUSCH repeated over a plurality of uplink subframes based on the second information.
8. The UE of claim 6 , wherein performing the blind decoding comprises:
performing first blind decoding on a first downlink sub-frame among the plurality of downlink sub-frames; and
performing second blind decoding on a second downlink sub-frame among the plurality of downlink sub-frames.
9. The UE of claim 6 , wherein:
the processor is further configured to determine a control channel element (CCE) aggregation level for transmitting the downlink control channels; and
the second blind decoding is performed based on the CCE aggregation level.
10. The UE of claim 6 , wherein:
the processor is further configured to determine a first control channel element (CCE) region in the first downlink sub-frame; and
the second blind decoding is performed on a second CCE region of the second downlink sub-frame, the second CCE region indicating a same resource allocation region as the first CCE region.
