Wireless communication method, enhanced Node B and user equipment
View Patent ↗A communication apparatus includes circuitry which, in operation, maps one or more repetitions of control information in a search space region, and a transmitter which, in operation, transmits the one or more repetitions of the control information. The search space region includes a first plurality of sub-regions of different lengths for a largest repetition number of the control information, and a second plurality of sub-regions of different lengths for a second-largest repetition number of the control information. An interval of subframes to which the first plurality of sub-regions are mapped is greater than an interval of subframes to which the second plurality of sub-regions are mapped.

The communication method according to claim 5 , wherein the first plurality of sub-regions are determined based on the largest repetition number of the control information, and the second plurality of sub-regions are determined based on the second-largest repetition number of the control information.
7. The communication method according to claim 5 , wherein the first plurality of sub-regions for the largest repetition number of the control information are mapped to a same starting subframe, and the second plurality of sub-regions for the second-largest repetition number of the control information are mapped to a same starting subframe.
8. The communication method according to claim 5 , wherein the search space region is determined based on physical layer signaling.
9. A communication apparatus comprising:
a receiver which, in operation, receives one or more repetitions of control information in a search space region,
wherein the search space region includes a first plurality of sub-regions of different lengths for a largest repetition number of the control information,

wherein an interval of subframes to which the first plurality of sub-regions are mapped is greater than an interval of subframes to which the second plurality of sub-regions are mapped; and
circuitry which, in operation, demodulates the one or more repetitions of the control information.
10. The communication apparatus according to claim 9 , wherein the first plurality of sub-regions are determined based on the largest repetition number of the control information, and the second plurality of sub-regions are determined based on the second-largest repetition number of the control information.
11. The communication apparatus according to claim 9 , wherein the first plurality of sub-regions for the largest repetition number of the control information are mapped to a same starting subframe, and the second plurality of sub-regions for the second-largest repetition number of the control information are mapped to a same starting subframe.
