Abstract:
1. A transmission method comprising: configuring a first search space according to a first search space configuration rule or configuring a second search space according to a second search space configuration rule, wherein the first search space configuration rule defines a number of first decoding region candidates corresponding to first control channel element (CCE) aggregation levels, and the second search space configuration rule defines a number of second decoding region candidates corresponding to second CCE aggregation levels, wherein the second CCE aggregation levels overlap with the first CCE aggregation levels and include at least one aggregation level smaller than any of the first CCE aggregation levels; mapping downlink control information on one of a plurality of decoding region candidates included in the first search space or on one of a plurality of decoding region candidates included in the second search space, each decoding region candidate being composed of a CCE or a plurality of aggregated CCEs with one of the firsst or second CCE aggregation levels defined by the first or second search space configuration rules, transmitting a signal including the mapped down link control signal.
