METHOD AND TERMINAL FOR RECEIVING BUNDLE OF EPDCCHS
First Claim
1. A method of receiving an enhanced physical downlink control channel (EPDCCH) by a user equipment (UE), the method comprising:
- determining a first search space for receiving an EPDCCH on a first subframe among N subframes when an EPDCCH bundle in which the same EPDCCH is repeated on the N subframes is to be received;
determining a second search space for receiving the EPDCCH on a second subframe among the N subframes, each of the first and second search spaces being determined based on a number of EPDCCH candidates, and the number of EPDCCH candidates being determined according to any one of a first case (case
1), a second case (case
2) and a third case (case
3) classified on the basis of a DCI format and whether a cyclic prefix (CP) being used is a normal CP or an extended CP; and
decoding the EPDCCH in the second search space of the second subframe when cases for determining the first search space and the second search space are the same.

Abstract
One disclosure of the present specification provides a method for receiving EPDCCH by an MTC device. The method comprises: a step for determining a first search space and a second search space for receiving EPDCCH on a first subframe and a second subframe, respectively, from among N-number of subframes, if a bundle of EPDCCHs in which the same EPDCCH is repeated on the N-number of subframes should be received, wherein each of the first and second search spaces is determined on the basis of the number of EPDCCH candidates, and determined by any one of a first case, a second case and a third case classified on the basis of a DCI format and whether a CP being used is a normal CP or an extended CP; and a step for decoding the EPDCCH in the second search space if the cases for determining the first search space and the second search space are the same.

10. A user equipment (UE) for receiving an enhanced physical downlink control channel (EPDCCH), the UE comprising:
-
a radio frequency (RF) unit; and a processor to determine a first search space for receiving an EPDCCH on a first subframe among N subframes when an EPDCCH bundle in which the same EPDCCH is repeated on the N subframes is tobe received through the RF unit, to decode the first subframe in the first search space, to determine a second search space for receiving the EPDCCH on a second subframe among the N subframes, and to decode the second subframe in the second search space, wherein the first and second search spaces are determined based on a number of EPDCCH candidates, the EPDCCH candidates are determined according to any one of a first case (case
1), a second case (case
2) and a third case (case
3), andthe processor decodes the second subframe when cases for the first search space and the second search space are the same. - View Dependent Claims (11, 12, 13)
